In this embodiment, the push rod 5 is vertically disposed above the guide groove 10, the front side of the lower end of the push rod 5 is provided with a first inclined plane 50, and the rear side of the top of the main slider 3 is provided with a second inclined plane 310 opposite to the first inclined plane 50; when the push rod 5 is pushed from top to bottom, the second inclined surface 310 slides relative to the first inclined surface 50 and pushes the main slider 3 to slide from the initial position to the end position.
The slide operation module in the present invention includes a slide portion 41 and an operation portion 42. The sliding portion 41 is disposed in the sliding hole of the main slider 3 and can slide along the forming direction of the sliding hole, in this embodiment, the forming direction of the sliding hole is perpendicular to the horizontal plane (i.e. perpendicular to the x-y plane shown in the figure), and the upper end of the sliding portion 41 extends out of the sliding hole; the operation portion 42 is connected to the upper end of the sliding portion 41 and protrudes outside the sliding hole.
The movable block 2 is disposed above the die plate 1 in the present invention, and is used to push the sliding portion 41 sliding to the final position downward. Specifically, the push rod 5 pushes the main slider 3 from the initial position to the end position, and in this process, the sliding operation module moves synchronously with the main slider 3, and the main slider 3 that has reached the end position stops sliding, and the movable press block 2 pushes the sliding portion 41 to slide downward.
As shown in fig. 6 and 7, when the sliding portion 41 slides downward under the pressure of the movable pressing block 2, the operating portion 42 moves downward synchronously with the sliding portion 41, so as to process and shape a workpiece to be processed between the die plate 1 and the movable pressing block 2, and in this embodiment, the workpiece to be processed is a sheet-shaped plate 8.
In the invention, after the operation part 42 finishes processing the sheet material 8, the sliding part 41 needs to drive the operation part 42 to automatically reset, and the guide floating block 6 in the invention is the sliding part 41 for jacking up and moving downwards, and the guide floating block 6 is positioned below the guide groove 10; more specifically, the guide slider 6 is positioned below the slide portion 41 in the slide hole of the main slider 3 slid to the end position. When the sliding part 41 drives the operating part 42 to move downwards, the lower end of the sliding part 41 is abutted to the upper surface of the guide floating block 6 and pushes the guide floating block 6 to move downwards synchronously, and after the operating part 42 finishes the processing and forming of the plate 8, the guide floating block 6 automatically rebounds upwards and resets the sliding part 41.
The bottom plate 7 is disposed below the die plate 1, and is provided with a first through hole (not shown) for guiding the slider 6 to move up and down. In some embodiments, the female mold plate 1 and the base plate 7 may be integrally formed.
Referring to fig. 3 and 5, the bottom of the guide slider 6 is provided with a first elastic member 91 that is pushed up, and in the specific implementation, the first elastic member 91 may be a mechanism such as a spring that can apply elastic force to the outside. When the first elastic member 91 lifts the guide slider 6 upward, the upper surface of the guide slider 6 and the upper surface of the bottom plate 7 are on the same plane and together form a slide path on which the main slider 3 slides. The guide slider 6, which is a part of the slide way, has a guide function at this time to ensure smooth sliding of the main slider 3 in the guide groove 10.
In some embodiments of the present invention, the bottom plate 7 may not be provided, and a track for sliding the main slider 3 may be formed between both sides of the sliding direction of the main slider 3 and the side walls of the guide groove 10, and the guide slider 6 may be used only for resetting the sliding portion 41 without a guide function.
In the embodiment shown in the drawings, the bottom of the guide slider 6 is formed with a boss 60 extending outward, and when the first elastic member 91 lifts up the guide slider 6, the boss 60 abuts against the lower surface of the bottom plate 7. The design can ensure that the upper surface of the guide floating block 6 is exactly in the same plane with the upper surface of the bottom plate 7 when the guide floating block 6 moves upwards, and can prevent the guide floating block 6 from excessively moving upwards under the pushing of the first elastic piece 91 to influence the normal operation of the whole device.
In this embodiment, the movable pressing block 2 is provided with a second through hole (not labeled in the figure) through which the push rod 5 vertically passes, and the push rod 5 passes through the second through hole and then is matched with the main sliding block 3, and in this embodiment, the moving direction of the movable pressing block 2 is consistent with the moving direction of the push rod 5. It will be appreciated that in other embodiments of the invention, the movable mass 2 may be provided separately from the push rod 5 and even the direction of movement may be inconsistent.
After the operation part 4 finishes the processing and forming of the plate 8, the main sliding block 3 also needs to be reset from the end position to the initial position, and in the specific implementation process of the invention, in order to realize the reset of the main sliding block 3, the main sliding block 3 is connected with a second elastic piece (not shown in the figure) for automatically rebounding from the end position to the initial position of the main sliding block 3; in the specific implementation process, the second elastic member may be a tension spring disposed between the main slider 3 and the end sidewall of the guide slot 10 at the initial position, or a compression spring disposed between the main slider 3 and the end sidewall of the guide slot 10 at the final position, which may be other structures capable of realizing the same function.
Referring to fig. 2 and 4, a relief groove 20 is formed at the bottom of the movable pressing block 2, wherein the relief groove 20 is formed by recessing upward from the bottom of the movable pressing block 2, and when the push rod 5 pushes the main sliding block 3 to move from the initial position to the end position, the upper end of the sliding portion 41 enters the relief groove 20. In some embodiments of the present invention, when the push rod 5 slides down and pushes the main slider 3 to slide, the movable pressing block 2 also moves down at the same time, so that the setting of the yielding groove 20 can effectively prevent the movable pressing block 2 from contacting with the sliding portion 41 before the main slider 3 reaches the end position, thereby ensuring that the movable pressing block 2 applies a force to the sliding portion 41 only after the main slider 3 reaches the end position. Of course, in other embodiments of the invention, the bottom of the movable press block 2 may be free of the relief groove 20, and it is also possible to increase the distance between the movable press block 2 and the cavity plate 1 appropriately.
As shown in fig. 4, 6, 8, 9 and 10, a forming table 40 (the forming table 40 is not shown in fig. 3, 5 and 7) that cooperates with the operation portion 42 to form the plate 8 is provided between the die plate 1 and the movable pressing block 2 in the present embodiment.
In particular, in this embodiment, the forming table 40 is a pair of opposite bosses fixed on the die plate 1, the operating portion 42 is a square bar with a shape matching with a space shape between the pair of bosses, and when the operating portion 42 moves downward, the plate 8 disposed on the two bosses is bent under the cooperation of the bosses and the square bar, so as to implement forming of a specific shape, in particular, in this embodiment, the formed plate 8 forms a square tubular structure, and as shown in fig. 10, two upwardly bent side walls 81 and 82 of the square tubular structure are formed by the operating portion 42 and the forming table 40.
It should be appreciated that the sheet material 8 shown in this embodiment is only a portion of the product to be processed, often the product to be processed has a three-dimensional spatial structure, and the sheet material 8 shown is generally located on the side of the product to be processed. In addition, the specific structures of the operation portion 42 and the forming table 40 shown in the present embodiment are only examples, and in other embodiments of the present invention, the shape structures of the operation portion 42 and the forming table 40 may be determined according to the requirements of the user, and the operation portion 42 may be used for implementing other processing technologies such as punching besides bending and forming of the plate 8.
The stamping die device of the invention can also be provided with other mechanisms for completing the processing and forming of the whole product to be processed, and the specific structure can refer to the existing design and is not excessively shown and described herein; the core of the present invention is the structure in which the main slider 3 slides in cooperation with the sliding portion 41 and the structure related thereto.
In the specific implementation process of the invention, when the movable pressing block 2 applies force to the sliding part 41, in order to make the plate 8 be rapidly punched and formed, the top of the movable pressing block 2 is connected with a third elastic piece for the sliding part 41 in the sliding hole of the main sliding block 3 sliding to the end position to move downwards. In some embodiments, the third elastic member 92 may be a spring or other mechanism capable of exerting an elastic force.
For a better understanding of the present invention, the following description will be made with reference to the embodiments shown in the drawings, in which the operation of the stamping die apparatus of the present invention is described in detail:
after the press die device starts to run, the push rod 5 moves downwards to push the main slider 3 to slide from the initial position of the guide groove 10 to the end position, and the lower end of the sliding part 41 in the sliding hole of the main slider 3 at the end position abuts against the upper surface of the guide slider 6. In some implementations, when the push rod 5 moves downward, the movable pressing block 2 may also draw toward the cavity plate 1 at the same time.
After the main slider 3 reaches the end position, the movable pressing block 2 moves downward to abut against the upper surface of the sliding portion 41 and drive the sliding portion 41 to move downward in synchronization with the guide slider 6 until the operation portion 42 completes the processing and forming of the plate 8. In this embodiment, specifically, after the main slider 3 reaches the end position, the third elastic member 92 releases the elastic force to drive the movable pressing block 2 to move downward, thereby indirectly pushing the sliding portion 41 to slide downward in the sliding hole forming direction, and the operating portion 42 moves synchronously with the sliding portion 41 to realize the processing and forming of the plate 8. In some embodiments of the present invention, the third elastic member 92 releases the elastic force after the main slider 3 reaches the end position, and the movement of the movable platen 2 is performed by other external forces before the third elastic member 92 releases the elastic force.
After the plate 8 is processed and molded, the movable pressing block 2 moves upwards, and the first elastic piece 91 jacks up the guide floating block 6 and the sliding part 41; the push rod 5 moves upwards, and the main sliding block 3 moves from the end position to the initial position; after the main slider 3 and the sliding portion 41 are reset, the operation portion 42 on the sliding portion 41 can be separated from the plate 8 to complete the core pulling operation. In the specific implementation process, the reset sequence of the main sliding block 3 and the sliding part 41 can be adjusted according to the requirement of a user; specifically, in practical designs, the main slider 3 and the sliding portion 41 may be reset synchronously, or the main slider 3 resets the sliding portion 41 first and then resets, or the slider 32 resets the main slider 3 times first and then resets.
It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.
The above list of detailed descriptions is only specific to practical embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments or modifications that do not depart from the spirit of the present invention should be included in the scope of the present invention.
