As shown in fig. 1 to 5, the apparatus 100 for cutting off a stem of an aluminum die-cast part includes a frame 10, a base 70 fixed to the frame, a movable plate 20 driven by a cylinder 202, a lower cutter 32, an upper cutter 31, an inclined slide plate 40, and a robot (not shown).

The manipulator grips the material handles of the workpiece to grasp the workpiece and then place it on the base 70, and grips the material handles all the time during the cutting process of the material handles to position the workpiece on the base 70.

The movable plate 20 is located above the base and movably connected to the frame, and is driven by the cylinder to move up and down relative to the base. The base 70 is fixedly provided with a lower cutter 32, and the movable plate 20 is fixedly provided with an upper cutter 31. When the movable plate moves downwards relative to the base, the lower cutter 32 acts on the lower surface of the material handle, the upper cutter 31 acts on the upper surface of the material handle, and the two cutters are extruded to clamp the material handle.

The inclined slide plate 40 is inclined from the top to the bottom, and the upper end thereof is abutted against the rear side of the base 70, and the center of gravity of the main body of the workpiece is located above the inclined slide plate for automatically lowering the processed workpiece to the next process.

In addition, the lower side of the movable plate is provided with an elastic pressing plate, the elastic pressing plate is used for pressing above the main body of the workpiece, the function of further fixing the workpiece is achieved, and meanwhile, a reverse force is given to the main body of the workpiece in the process that the movable plate is lifted through elastic force, and the machined workpiece is helped to fall along the inclined sliding plate 40.

When the movable plate moves downwards, the upper cutter 31 presses downwards to engage with the lower cutter 31 to bite the root of the material handle d1 on the front side of the workpiece d, and the elastic pressing plate 21 presses above the workpiece d. After the material handle d1 is cut off, the fixing point on the front side of the workpiece d is released, the upper tool 31 and the elastic pressing plate 21 move up along with the movable plate 20, and the main body of the workpiece slides down from the inclined slide plate 40 under the action of its own weight.

Preferably, the upper cutter 31 is mounted on the front side of the movable plate 20, and the elastic pressing plate 21 is mounted on the rear side of the movable plate 20.

It should be understood that the upper tool 31 and the lower tool 32 jointly bite into the root of the shank d1 on the front side of the workpiece d, and then the workpiece d is preliminarily fixed, and then the elastic pressing plate 21 is pressed above the workpiece d, thereby positioning the workpiece d in the four directions of up, down, front, and rear.

As shown in fig. 6, the elastic pressing plate 21 includes a flexible pressing plate a1, a guiding column a2 and a spring a3, the flexible pressing plate a1 is movable relative to the movable plate 20 through the guiding column a2, and the spring a3 is sleeved on the guiding column a 2; after the material handle d1 is cut off, when the movable plate 20 moves upwards, the compressed spring a3 is released on the flexible pressing plate a1, and the flexible pressing plate a1 has a momentary downward force on the workpiece d, so that the workpiece d slides downwards towards the inclined sliding plate 40.

The flexible pressure plate a1 is contacted with the workpiece d, so that the surface of the workpiece d is not damaged; when the flexible pressure plate a1 is pressed down, the spring a3 is compressed; when the movable plate 20 moves upwards, the spring a3 is charged and released instantaneously, and a downward force is applied to the workpiece d through the flexible pressing plate a1, so that the workpiece d slides downwards along the inclined sliding plate 40.

The lower surface a0 of flexible platen a1 is shaped to conform to the contour of the upper surface of workpiece d. So as to better press over the workpiece d.

The lower cutter 32 includes a lower base b1 and a blunt edge b2 protruding from a side of the lower base b1, and the upper cutter 31 includes an upper base c1 and a sharp edge c2 protruding from a side of the upper base c 1.

The upper surface of the lower base b1 can be used as a resting surface of the material handle d1, so that the stability of the workpiece d is facilitated; the cooperation of the blunt edge b2 with the sharp edge c2 cuts the slug d 1.

As shown in fig. 1 and 2, the cutting device for the aluminum die-casting part material handle further comprises a laser sensor 50, wherein the laser sensor 50 is arranged beside the base and emits a detection light Y to the base to detect whether the base is empty or not. Meanwhile, the laser sensor is communicated with a controller for controlling the operation of the manipulator, the detection information can be sent to the controller, and the controller receives signals and gives corresponding instructions to control the movement of the manipulator.

As shown in fig. 4, the upper end of the inclined slideway is provided with a support frame, and the support frame 41 comprises an inclined support surface 42 matched with the bottom of the workpiece d. The bottom of the workpiece d can be seated on the inclined supporting surface 42 of the supporting frame, and when the flexible pressing plate a1 is released; the inclined support surface 42 does not prevent the workpiece d from sliding down from the inclined slide plate 40 by its own weight.

The apparatus for cutting out the aluminum die cast piece shank d1 further includes a conveyor belt 60 that interfaces with the inclined slide plate 40. The conveyor belt 60 conveys the workpiece with the material handle d1 cut off to the next processing link.

As shown in fig. 1 and 2, the frame 10 includes a lower plate 205 fixed to the base and an upper plate 201 erected above the lower plate 205, a guide column 203 is disposed between the lower plate and the upper plate, and the movable plate 20 moves up and down along the guide column 203.

Further, the cylinder 202 for driving the movable plate is fixed on the upper base plate, and the lower end of the movable shaft 1 of the cylinder penetrates through the upper base plate and is connected with the movable plate so as to drive the movable plate to move. The movable plate 20 is provided with a guide hole for the guide post to pass through, and a movable guide sleeve K is arranged on the guide hole to guide the movement of the movable plate.

In other embodiments, a blocking rod can be movably arranged on the outer side of the workpiece. When the manipulator places the work piece on the base, the stop lever butts against the outside of work piece to further play the positioning action to its front side. When the material handle is cut off and the movable plate is lifted, the blocking rod leaves the outer side of the workpiece so as to remove the blocking of the workpiece body which falls in advance.

The movement of the blocking rod can be driven by a motor or a lever cylinder. The motor or the lever cylinder is controlled by a control circuit in the controller, and can be coordinated and matched with the mechanical arm and the movable plate through reasonable programming to finish the operation of the whole process of feeding, cutting and blanking.

In the description of the present invention, it is also to be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "coupled" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The above detailed description of the apparatus for cutting off an aluminum die-cast part stem provided by the present invention is provided, and the principle and the embodiment of the present invention are explained herein by using specific examples, and the above description of the embodiments is only used to help understanding the present invention and the core idea. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
