Technical Field

The invention relates to the technical field of vehicle door edge covering, in particular to a stamping edge covering mechanism.

Background

In the design of a conventional vehicle door edge covering die, the condition that edge covering is needed at a windowsill is often met, but because the structural space of a windowsill assembly of a vehicle door is very small, when edge covering is carried out by using a conventional rotary edge covering mechanism, interference is generated on pre-edge covering and final edge covering, and the vehicle door cannot be stamped and covered at one time. At this time, equipment and stations are required to be added independently to edge the windowsill assembly, but this undoubtedly causes reduction of production efficiency, excessive occupation of space in a factory and improvement of production cost.

Because the vertical interval of the first driving part and the edge covering pulley is smaller than the vertical interval of the second driving part and the edge covering pressing block, when the die is closed, the first driving part can be firstly contacted with the edge covering pulley and drives the edge covering pulley and the edge covering pressing block to linearly displace towards a product to be covered with the edge, and in the process, the edge covering pressing block can be contacted with the turned edge of the product to be covered with the edge and can push the turned edge to turn over the product to complete the pre-covering of the product to be covered with the edge. And then, the second driving part can be in contact with the edge covering press block and drives the edge covering press block to vertically displace relative to the edge covering pulley so as to vertically compress the turned edge after pre-edge covering and further finish final edge covering.

The pre-edging action and the final edging action of the stamping and edging mechanism are carried out in two steps, the pre-edging action is linear displacement of the edging pulley and the edging press block in a set direction, compared with the rotary edging in the background technology, the linear displacement can relatively easily enter a windowsill assembly with narrow space, and the edging press block can complete the final edging by matching with the acting force of a second driving part, so that the stamping and edging can be completed at one time.

Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

The terms "first," "second," and the like, herein are used for convenience in describing two or more structures or components that are identical or similar in structure and/or function and do not denote any particular limitation in order and/or importance.

Referring to fig. 1-2, fig. 1 is a schematic structural diagram of an embodiment of a stamping and taping mechanism provided in the present invention, and fig. 2 is a schematic structural diagram of a taping pulley, a taping press block, and a return reset component.

As shown in fig. 1 and 2, the invention provides a stamping and taping mechanism, which comprises an upper die 1, a lower die 2, a taping pulley 3 and a taping press block 4, wherein the taping pulley 3 is connected with the lower die 2 in a sliding manner in a set direction, the taping press block 4 is connected with the taping pulley 3 in a sliding manner in a vertical direction, an elastic piece 32 is arranged between the taping press block 4 and the taping pulley 3 and used for positioning the position of the taping press block 4 relative to the taping pulley 3 in a normal state, and an included angle is formed between the set direction and the vertical direction; the upper die 1 is further provided with a first driving part 11 and a second driving part 12, the vertical distance between the first driving part 11 and the edge covering pulley 3 is smaller than the vertical distance between the second driving part 12 and the edge covering press block 4, the first driving part 11 is used for driving the edge covering pulley 3 and the edge covering press block 4 to be close to a product A to be covered with edge, pre-covering is completed through the edge covering press block 4, and the second driving part 12 is used for driving the edge covering press block 4 to perform vertical displacement so as to complete final edge covering.

In an initial state, the upper die 1 and the lower die 2 can be in a separated state, a product a to be covered can be placed on the lower die 2, and then the upper die 1 can be controlled to vertically displace towards the lower die 2 so as to carry out die assembly.

Because the vertical distance between the first driving part 11 and the edge covering pulley 3 is smaller than the vertical distance between the second driving part 12 and the edge covering press block 4, when the die is closed, the first driving part 11 can be firstly contacted with the edge covering pulley 3 and drives the edge covering pulley 3 and the edge covering press block 4 to linearly displace towards the product A to be covered, and in the process, the edge covering press block 4 can be contacted with the turned edge (not marked in the figure) of the product A to be covered and can push the turned edge to turn over, so that the pre-covering of the product A to be covered is completed. Then, the second driving part 12 may contact with the hemming pressing block 4 and drive the hemming pressing block 4 to vertically displace relative to the hemming trolley 3 to vertically press the hemmed after the pre-hemming, thereby completing the final hemming.

The pre-binding action and the final binding action of the stamping binding mechanism provided by the invention are carried out in two steps, the pre-binding action is taken as the linear displacement of the binding pulley 3 and the binding press block 4 in the set direction, compared with the rotary binding in the background technology, the linear displacement described above can be relatively easily incorporated into a window sill assembly having a small space, which, in conjunction with fig. 1, may generally include an inner panel assembly a1 and an outer panel assembly a2, after the taping compact 4 has entered the gap between the inner panel assembly a1 and the outer panel assembly a2, and then the edge covering press block 4 can complete the final edge covering of the outer plate assembly A2 by matching with the acting force of the second driving part 12, therefore, the stamping and edge covering can be completed at one time, equipment and stations do not need to be added independently, the production efficiency is high, the occupation of the space in a factory building can be reduced, and the production cost can be greatly reduced.

It should be noted that, although the press hemming mechanism provided by the present invention is designed primarily for hemming a relatively narrow space member such as a sill assembly, this does not mean that the press hemming mechanism can be used only for hemming a member such as a sill assembly, and it can be used for hemming other members or other portions of a vehicle door.

It should be noted that the upper die 1 and the lower die 2 have other configurations in addition to the hemming trolley 3, the hemming press 4, the first driving member 11, the second driving member 12, and the like, but these configurations are not particularly relevant to the core invention of the present invention, and therefore, they will not be described in detail, and they can be understood with reference to the related art.

The aforementioned elastic member 32 may directly interact with the edge-covering compact 4. Or, the installation seat 5 may be further included, the edge covering press block 4 may be fixed to the installation seat 5, two ends of the elastic member 32 may respectively act on the installation seat 5 and the edge covering pulley 3, and at this time, the elastic member 32 may indirectly act on the edge covering press block 4 through the installation seat 5. When the second driving member 12 acts on the hemming press block 4 to enable the hemming press block 4 to move vertically downwards, the deformation amount of the elastic member 32 can be increased to accumulate energy, and when the acting force of the second driving member 12 disappears, the energy accumulated by the elastic member 32 can be released to drive the hemming press block 4 to return to the mounting position under the normal state (when the second driving member 12 does not act).

The deformation of the elastic element 32 may be a tensile deformation or a compressive deformation, depending on the installation position of the elastic element 32, and in the solution of the figures, the deformation of the elastic element 32 may be a compressive deformation. The elastic member 32 may be different in kind for different deformation forms, for example, the elastic member 32 may be a tensile string, a linear spring, or the like when the deformation is tensile, and the elastic member 32 may be an elastic block, a linear spring, or the like when the deformation is compressive.

Further, a limiting part 6 can be further included, the limiting part 6 can be installed on one of the installation seat 5 and the taping pulley 3 and can act with the other of the installation seat 5 and the taping pulley 3 to limit the distance of the installation seat 5 relatively far away from the taping pulley 3 in the vertical direction, and a limiting connection relation between the installation seat 5 and the taping pulley 3 can be established to avoid the vertical separation of the installation seat 5 and the taping pulley 3.

In a specific scheme, the mounting seat 5 can be provided with a stepped hole 51, and the stepped hole 51 can comprise a large-diameter hole section and a small-diameter hole section along the direction close to the edge-wrapping pulley 3, and a stepped surface can be formed between the large-diameter hole section and the small-diameter hole section; the limiting part 6 can comprise a rod part and a head part, the radial size of the head part is larger than that of the rod part, the rod part can penetrate through the small-diameter hole section and is connected with the edge covering pulley 3 in an assembling state, the head part can be located in the large-diameter hole section, and the radial size of the head part can be larger than that of the small-diameter hole section. So set up, the head can be in vertical with the step face and support to prescribe a limit to mount pad 5 in the vertical relative maximum distance away from bordure smooth car 3.

The types of the limiting parts 6 comprising the rod parts and the head parts can be selected more, for example, the limiting parts 6 can be bolts, the rod parts can be provided with external threads, and then can be in threaded connection with the edge-covered pulley 3, or the rod parts can not be provided with external threads, and at the moment, the rod parts and the edge-covered pulley 3 can be fixed in a welding mode and the like.

In addition, the limiting structure composed of the limiting component 6 including the rod part and the head part and the stepped hole 51 can limit the vertical displacement of the mounting seat 5, and the rod part and the small-diameter hole can also limit the displacement direction of the mounting seat 5 through matching, so as to guide the vertical sliding of the mounting seat 5 relative to the taping pulley 3.

It should be noted that the above-mentioned position-limiting component 6 including the rod part and the head part is only an exemplary illustration of the specific structure of the position-limiting component 6 according to the embodiment of the present invention, and the position-limiting component 6 may also take other structural forms, for example, a position-limiting stopper or the like provided on the edge-covering pulley 3, if the function is satisfied; in addition, the limiting component 6 including the rod part and the head part is also integrated with a guiding function, and in practical application, the guiding function can be separated independently, and a special guiding component is further arranged, which is also an available option.

Aiming at the limiting part 6 comprising the rod part and the head part, the elastic part 32 can be a spring, the spring can be sleeved outside the rod part, and two ends of the spring can respectively abut against the edge-covering pulley 3 and the mounting seat 5. Therefore, the rod part can also play a role of a spring column for limiting the radial movement of the spring, and the stability of the spring in the using process is favorably ensured.

Further, the edge covering pulley 3 may further include an installation groove 31, the rod of the position limiting member 6 may be connected to a bottom wall of the installation groove 31, and at least a portion of the elastic member 32 may be located in the installation groove 31. So set up, mounting groove 31 forms a hidden structure, and the elastic component 32 that sets up in mounting groove 31 exposes only locally at most, and in the use, the elastic component 32 receives external destruction or the possibility of disturbing littleer, and life and stability all can improve.

With continued reference to fig. 1, at least one of the two surfaces of the mounting block 5 that slide relative to the tipping block 3 may be provided with a wear plate 33 to increase wear resistance. The material of the wear plate 33 is not limited herein, and may be determined according to actual needs.

In the process of die assembly, the upper die 1 needs to move vertically downwards, and the displacement form is the same as that required by final edge covering of the edge covering pressing block 4, so that the second driving part 12 only needs to adopt a structural member, such as a column, a pressing block and the like, which can vertically contact with the edge covering pressing block 4 and drive the edge covering pressing block 4 to move.

For the relative sliding of the hemming trolley 3 and the lower die 2, the aforesaid set direction may be a direction perpendicular to the vertical direction, in which case the hemming trolley 3 slides in a horizontal plane, or the aforesaid set direction may form an angle different from 90 degrees with the vertical direction, in which case the hemming trolley 3 slides in an inclined plane (inclined with respect to the horizontal plane).

Since the displacement direction of the upper die 1 during the die assembly process is not consistent with the sliding direction of the taping pulley 3, at least one of the two surfaces where the first driving member 11 and the taping pulley 3 interact may further be provided with a guide portion that can convert the downward displacement generated by the upper die 1 into the displacement of the taping pulley 3 in a set direction.

For convenience of description, the guide portion provided to the first driving member 11 may be referred to as a first guide portion 111, and the guide portion provided to the hemming block 3 may be referred to as a second guide portion 34.

Still taking fig. 1 as a viewing angle, at least the lower end of the first guiding portion 111 may be provided with a first inclined surface portion 111a forming a non-90-degree included angle with the vertical direction, at least the upper end of the second guiding portion 34 may be provided with a second inclined surface portion 341 forming a non-90-degree included angle with the vertical direction, and the first inclined surface portion 111a and the second inclined surface portion 341 cooperate to convert the driving force generated by the first driving component 11 in the vertical direction into the driving force in the set direction, so as to drive the hemming trolley 3 to displace in the set direction.

Both the two guide parts need to bear sliding friction, so both the two guide parts can be made of wear-resistant materials with higher hardness to meet the requirements of long-term use.

As mentioned above, the set direction may also form an angle different from 90 degrees with the vertical direction, and at this time, the sliding of the taping pulley 3 relative to the lower die 2 under the action of the first driving part 11 may have a certain gradient. If the gradient is a downward gradient (relatively downward displacement while moving towards the product A to be covered), the friction force of the covering pulley 3 when moving towards the product A to be covered can be reduced; if this gradient is an upward gradient (which is displaced relatively upward while being displaced toward the product a to be covered), then, when the force of the first driving member 11 disappears, the gravity of the covering sled 3 itself can assist the sliding of the covering sled 3 with respect to the lower mold 2 to perform the resetting.

The sliding fit structure between the hemming trolley 3 and the lower die 2 is not limited herein as long as the use requirement can be met.

Further, as shown in fig. 2, a return unit 7 may be further included, which may interact with the hemming trolley 3 to return the hemming trolley 3 when the force of the first driving unit 11 is removed. The return stroke reset component 7 can be a cylinder, an oil cylinder and other components, and can also be a spring and an elastic block. Tensile cords and the like.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
