Referring to fig. 9 to 10, the water tank may be formed by bending and welding a cross-shaped plate (or a plate 900 to be processed). The bottom of the sink (i.e. the bottom plate 910) is generally provided with a drain hole 912, and the drain hole 912 can be a round hole, a square hole or a hole with other shapes; it should be understood that after the drain hole 912 is formed, it is generally punched to make the peripheral area of the drain hole 912 depressed so that the drain hole 912 is at the lowest position of the sink for easy drainage. A flow guide line 911 can be further processed at the bottom of the water tank, one end of the flow guide line 911 is connected with the side wall of the water tank (generally connected to the corner of the water tank), and the other end is communicated with a water discharge hole 912; it will be appreciated that when the drain hole 912 is in the middle region of the sink, four flow guide lines 911 are generally formed, generally in an X-shape, and when the drain hole 912 is in the edge region of the sink, two flow guide lines 911 are generally formed, generally in a V-shape; the guide line 911 is lower than the surrounding area, and the water in the water tank actively flows to the guide line 911 and then flows into the drain hole 912 from the guide line 911, so the guide line 911 is provided to guide the flow direction of the water flow in the water tank, drain the water conveniently, and keep dry when the water tank is not used.

The base 100 is a basic carrier for installing and fixing the components of the device, is a conceptual object, and can be any object, such as an object formed by combining one or more components of a metal table, a stone table, a wood table, a support, a supporting plate, a supporting frame, a ground and the like, and plays a role in fixing and supporting.

The track structure 200 is provided with a structure that can be slidably connected to other objects, such as one or more sliding grooves or a track bar, and a combination thereof. The bending lower die 300 is provided with a structure corresponding to the rail structure 200 and capable of being slidably connected to another object, so as to be slidably connected to the rail structure 200. The first mode is that the sliding connection is convenient to disassemble and assemble, so that different bending lower dies 300 can be replaced according to actual requirements, and water tanks of different types can be processed conveniently; and the sliding connection structure plays a certain limiting and positioning role, so that after the lower bending die 300 is installed on the sliding rail structure 200, the first bending groove 310 (or the second bending groove 320, the third bending groove, etc.) of the lower bending die 300 can always be aligned with the bending knife 400, so that the bending knife 400 correctly extends into the first bending groove 310 when moving downwards, and other parts of the lower bending die 300 are prevented from being touched when the bending knife 400 moves downwards, so that danger is generated, or equipment is damaged. It is to be understood that the first bending groove 310 (and the second bending groove 320) may be a V-shaped groove, a U-shaped groove, a Z-shaped groove, or the like. It should be understood that the slide rail structure 200 includes not only the structure for sliding connection with other objects, but also the base for carrying the structure and other objects, and the base acts like the base 100 and is a basic carrier.

The bending blade 400 is coupled to the base 100, typically in a sliding manner, and is drivingly coupled to a driving member, which is driven by the driving member, such that the bending blade 400 moves up and down to move away from or toward the first bending slot 310. It should be understood that the distance that the bending knife 400 moves downwards and the downward pressing force can be controlled by a program, for example, when a cross-shaped plate (or a plate to be processed) is bent to form a water tank cube, the bending degree is large, so that the distance that the bending knife 400 moves downwards is large, the depth of the bending knife extending into the first bending groove 310 is deep, and the cross-shaped plate can be bent more; when the guide line 911 is processed, the bending degree is small (even a certain indentation is needed), so the downward moving distance of the bending knife 400 is small, and the distance extending into the first bending groove 310 is short, so that the bending degree of the plate 900 to be processed is small; therefore, different parts of the water tank can be processed by switching different programs.

The lifting member 500 is provided, and the lifting member 500 lifts up one end of the lower bending die 300 to make the upper end surface of the lower bending die 300 in an inclined state, so when the board 900 to be processed is placed on the lower bending die 300, one end of the board 900 to be processed (generally, the drain hole 912 is provided therein) is located at a higher position, and when the bending knife 400 is close to the first bending groove 310 of the lower bending die 300, although both ends of the bending knife 400 move down by the same distance, one end of the bending knife 400 is deeper into the lower bending die 300 than the other end of the bending knife 400, so that one end of the board 900 to be processed is pressed into the first bending groove 310 by the bending knife 400 and is pressed into a deeper position (the indentation is deeper or the bending degree is greater), and similarly, the other end of the board 900 to be processed is pressed to a shallower position, so that a board can be formed along the direction of the diversion line 911 The larger the sinking degree of the guide line 911 is (or the deeper the groove depth of the groove of the guide line 911 is), the guide line 911 facilitates the water flow to flow into the drain hole 912 along the guide line 911, so that the water tank can completely drain the water, the dryness of the water tank is maintained, and the breeding of bacteria in a humid environment is effectively inhibited; so be provided with lifting piece 500, need not process water conservancy diversion line 911 through other equipment, can process on original basin bending equipment, and the water conservancy diversion of the water conservancy diversion line 911 of processing is effectual. It should be understood that after the bending device finishes machining the diversion line 911, the lifting member 500 is removed, and the plate 900 to be machined can be bent continuously, so that the sink side plate 920 on the plate 900 to be machined is erected to form a sink side wall (or can be further bent to form a sink side plate 930).

Referring to fig. 4 to 8, in some embodiments of the present invention, the present invention further includes a positioning element 600, a lower end of the positioning element 600 is connected to the sliding rail structure 200, and an upper end of the positioning element 600 is used for inserting into a water drainage hole 912 of the sink.

Because the diversion line 911 generally extends from the drain hole 912 to the sink sidewall; the positioning element 600 is arranged, the positioning element 600 is connected with the slide rail structure 200, the center of the positioning element 600 and the first bending groove 310 on the bending lower die 300 are ensured to be on the same straight line (so that the guide line 911 can pass through the center of the drain hole 912), and when the guide line 911 is processed, the drain hole 912 on the plate to be processed is sleeved at the upper end of the positioning element 600, so that a certain positioning and fixing effect can be achieved, and the positioning of the water tank is facilitated; moreover, when the drain hole 912 is a circular hole and the upper end of the positioning member 600 is cylindrical, after a current-guiding line 911 is processed, the next current-guiding line 911 can be processed continuously only by rotating the plate to be processed around the positioning member 600 and rotating the plate to be processed to a proper angle, so that a plurality of current-guiding lines 911 can be processed in sequence conveniently, and the production and processing of the water tank are facilitated. It should be understood that the side edge of the upper end of the positioning column is generally provided with a round corner or a chamfer, so that the plate 900 to be processed can be conveniently sleeved in. It should be understood that the lower end of the positioning member 600 and the sliding rail structure 200 may be fixedly connected, and once positioning is performed, the water tank can be directly processed, which is simple and convenient; the positioning member 600 can be detachably or slidably connected, so as to facilitate the assembly, disassembly and replacement of the positioning member 600, facilitate the replacement of positioning members 600 with different sizes to adapt to the processing of sinks with different specifications (for example, different sizes of the drain holes 912), or detach the positioning member 600 when the flow guide line 911 is not processed, and leave the space on the slide rail structure 200 for other processing operations.

Referring to fig. 4 to 10, in some embodiments of the present invention, the present invention further includes a limiting member 700, one end of the limiting member 700 abuts against the lifting member 500 or the bending lower die 300, and the other end of the limiting member 700 abuts against the positioning member 600.

Referring to fig. 9 and 10, after the drain hole 912 is formed, it is generally punched to make the peripheral area of the drain hole 912 depressed (forming a depressed area), so that the drain hole 912 is at the lowest position of the sink for draining water. Therefore, when the guide line 911 is processed, the other end of the guide line 911 needs to be communicated into the sunken area, so that water can smoothly flow into the drain hole 912, and preferably, the other end of the guide line 911 cannot be directly communicated with the drain hole 912 (i.e., the other end of the guide line 911 needs to be away from the drain hole 912 and cannot be directly communicated together), thereby preventing the guide line 911 from extending into the sunken area, and the bending deformation of the guide line 911 has a certain influence on the stamping step. The positioning member 600 is spaced apart from the lower bending die 300 (or the bending blade 400) by a predetermined distance, which is constant when the punching specification is unchanged. Therefore, by providing the limiting member 700, one end of the limiting member 700 abuts against the lifting member 500 (or directly abuts against the bending lower die 300), and the positioning member 600 abuts against the other end of the limiting member 700, so that the positioning member 600 is positioned at a correct distance, and the processed guide line 911 is just communicated to the sinking region and does not extend excessively. It should be understood that the length of the limiting member 700 and the stamping specification are corresponding, and when the stamping specification is changed, the processing can be continued by changing the limiting member 700 with the corresponding length.

Referring to fig. 4, 5 and 6, in some embodiments of the present invention, the lower end of the positioning member 600 is slidably connected to the sliding rail structure 200.

The lower end of the positioning member 600 is slidably connected to the sliding rail structure 200, so that the positioning member 600 can be conveniently slidably positioned, the positioning member 600 can be conveniently disassembled and replaced, the positioning member 600 with different sizes can be conveniently replaced to adapt to the processing of water tanks with different specifications (such as different sizes of the water drain holes 912), or the positioning member 600 can be disassembled when the flow guide line 911 is not processed, and the space on the sliding rail structure 200 is left for other processing operations. The sliding connection plays a certain role in limiting and fixing, so that the positioning element 600 is firmly connected after being assembled, and cannot be easily loosened and separated from the sliding rail structure 200, and particularly cannot be easily dragged by the plate 900 to be processed during processing.

Referring to fig. 4, 5 and 6, in some embodiments of the invention, the lower end of the limiting member 700 is slidably connected to the sliding rail structure 200.

The slide block and the first slide rail are arranged, so that the left and right positions of the rear positioning can be conveniently adjusted, and the plates 900 to be processed with different sizes or positions can be positioned.

Referring to fig. 1 and 2, in some embodiments of the present invention, a second slide rail is further included, the first slide rail and the second slide rail being slidably connected, the second slide rail being connected to the base 100.

Set up the second slide rail, be convenient for adjust the front and back position of back location, when curb plate 920 width (or basin degree of depth, height) difference, adjust.

Referring to fig. 4 to 8, a method for processing a water tank according to an embodiment of the present invention includes the steps of: lifting, namely inserting a lifting piece 500 below one end of the lower bending die 300 to enable the lifting piece 500 to be located between the lower bending die 300 and the sliding rail structure 200 and lift one end of the lower bending die 300; and bending, namely placing the plate 900 to be processed on the lower bending die 300, enabling the processing area of the drain hole 912 of the plate 900 to be processed to be at a higher position, and moving the bending knife 400 to the lower bending die 300 to bend the plate 900 to be processed.

Referring to the above, one end of the lower bending die 300 is lifted upwards through the lifting step, so that the upper end surface of the lower bending die 300 is in an inclined state, so that in the bending step, one end of the to-be-processed plate 900 (generally, the drain hole 912 is disposed therein) is located at a higher position, and when the bending knife 400 is close to the first bending groove 310 of the lower bending die 300, both ends of the bending knife 400 are moved downwards by the same distance, but one end of the bending knife 400 is deeper into the lower bending die 300 than the other end of the bending knife 400, so that one end of the to-be-processed plate 900 is pressed into the first bending groove 310 by the bending knife 400 and is pressed into a deeper position (the indentation is deeper or the bending degree is greater), and similarly, the degree of pressing the other end of the to-be-processed plate 900 is shallower, so that a diversion line 911 with a greater sinking degree (or a deeper groove of the diversion line 911 groove) along the diversion line 911 direction can be formed, the water flow can conveniently flow into the drain hole 912 along the guide line 911 by the guide line 911, so that the water tank can completely empty the water, the dryness of the water tank is kept, and the breeding of bacteria in a humid environment is effectively inhibited. Therefore, the guide line 911 does not need to be processed by other equipment through the lifting step, the water can be processed on the original water tank bending equipment, and the guide effect of the processed guide line 911 is good. It should be understood that after the bending step, the lifting member 500 is removed, and the bending device can be used to bend the plate 900 to be processed again, so that the trough side plate 920 on the plate 900 to be processed is erected to form a trough side wall (and can be further bent to form a trough side plate 930). It should be understood that the processed area of the drainage hole 912 of the board 900 to be processed is generally cut to form the drainage hole 912, and in a special case, the drainage hole 912 is not processed and is the processed area. It should be understood that the processing area of the drain hole 912 of the plate material 900 to be processed is located at a higher position, and the higher position is relative to the area of the plate material 900 to be processed between the bending blade and the lower bending die. It should be understood that, in the bending step, the distance that the bending knife 400 moves downwards and the downward pressing force can be controlled by a program, for example, when the cross-shaped plate (or the plate to be processed) is bent to form the water tank cube, the bending degree is large, so that the distance that the bending knife 400 moves downwards is large, the depth of the bending knife extending into the first bending groove 310 is deep, and the cross-shaped plate can be bent more; when the guide line 911 is processed, the bending degree is small (even a certain indentation is needed), so the downward movement distance of the bending knife 400 is small, and the distance extending into the first bending groove 310 is short, so that the bending degree of the plate 900 to be processed is small.

Referring to fig. 4 to 8, in some embodiments of the present invention, a positioning step is further included, in the positioning step, the positioning element 600 is placed on the slide rail structure 200, so that the positioning element 600 is placed on a side close to one end of the bending lower die 300, and in the bending step, the drainage hole 912 of the plate material 900 to be processed is sleeved on the positioning element 600.

Because the diversion line 911 generally extends from the drain hole 912 to the sink sidewall; in the bending step, the drain hole 912 on the plate to be processed is sleeved on the upper end of the positioning element 600, so that a certain positioning and fixing effect can be achieved, and the positioning element 600 is convenient to position the water tank; moreover, when the drain hole 912 is a circular hole and the upper end of the positioning member 600 is cylindrical, after a current-guiding line 911 is processed, the next current-guiding line 911 can be processed continuously only by rotating the plate to be processed around the positioning member 600 and rotating the plate to be processed to a proper angle, so that a plurality of current-guiding lines 911 can be processed in sequence conveniently, and the production and processing of the water tank are facilitated. It should be understood that the side edge of the upper end of the positioning column is generally provided with a round corner or a chamfer, so that the plate 900 to be processed can be conveniently sleeved in. It should be understood that after the lifting step, one end of the bending lower die 300 is higher and the other end is lower, and the positioning member 600 is placed at a side near the higher end of the bending lower die 300. It should be understood that the lower end of the positioning member 600 and the sliding rail structure 200 may be fixedly connected, and once positioning is performed, the water tank can be directly processed, which is simple and convenient; the positioning member 600 can be detachably or slidably connected, so as to facilitate the assembly, disassembly and replacement of the positioning member 600, facilitate the replacement of positioning members 600 with different sizes to adapt to the processing of sinks with different specifications (for example, different sizes of the drain holes 912), or detach the positioning member 600 when the flow guide line 911 is not processed, and leave the space on the slide rail structure 200 for other processing operations. It should be understood that one end of the guide line 911 is generally connected to the four corners of the water tank, so the guide line 911 is positioned such that the vertices of the missing four corners of the sheet material 900 to be processed are aligned with the first bending groove 310.

Referring to fig. 4 to 10, in some embodiments of the invention, in the positioning step, the limiting member 700 is placed on the sliding rail structure 200, such that one end of the limiting member 700 abuts against the lifting member 500 and the positioning member 600 abuts against the other end of the limiting member 700.

Referring to fig. 9 and 10, after the drain hole 912 is formed, it is generally punched to make the peripheral area of the drain hole 912 depressed (forming a depressed area), so that the drain hole 912 is at the lowest position of the sink for draining water. Therefore, when the guide line 911 is processed, the other end of the guide line 911 needs to be communicated into the sunken area, so that water can smoothly flow into the drain hole 912, and preferably, the other end of the guide line 911 cannot be directly communicated with the drain hole 912 (i.e., the other end of the guide line 911 needs to be away from the drain hole 912 and cannot be directly communicated together), thereby preventing the guide line 911 from extending into the sunken area, and the bending deformation of the guide line 911 has a certain influence on the stamping step. The positioning member 600 is spaced apart from the lower bending die 300 (or the bending blade 400) by a predetermined distance, which is constant when the punching specification is unchanged. Therefore, by disposing the limiting member 700 in the positioning step, one end of the limiting member 700 abuts against the lifting member 500, and the positioning member 600 abuts against the other end of the limiting member 700, so that the positioning member 600 is positioned at a correct distance, and the processed guide line 911 is just communicated to the sinking region and does not extend excessively. It should be understood that the length of the limiting member 700 and the stamping specification are corresponding, and when the stamping specification is changed, the processing can be continued by changing the limiting member 700 with the corresponding length.

Referring to fig. 4 to 10, in some embodiments of the present invention, a punching step is further included, in which the periphery of the drain hole 912 on the prefabricated plate material is punched such that the periphery of the drain hole 912 is depressed.

Through the stamping step, the drain hole 912 is located at the lowest part of the water tank, which facilitates drainage.

Referring to fig. 4 to 10, in some embodiments of the present invention, in the bending step, the lifting member 500 is removed, the joint between the side plate 920 and the bottom plate 910 of the plate material 900 to be processed is placed under the bending knife 400, and the bending knife 400 moves toward the bending lower die 300 to bend the plate material 900 to be processed.

The water tank is further bent to erect the side plate 920 of the water tank.

Referring to fig. 4 to 10, in some embodiments of the present invention, in the bending step, the lifting member 500 is removed, a joint between the side plate 930 and the side plate 920 of the plate material 900 to be processed is placed under the bending knife 400, and the bending knife 400 moves toward the bending lower die 300 to bend the plate material 900 to be processed.

The processing water tank is further bent, and the edge plate 930 of the water tank is processed.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
