Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figure 1-3 The embodiments of this utility model include: A self-adjusting stamping and forming die includes the following structure: an upper die assembly 1, a driving wedge 2, a lower die assembly 3, a lifting and forming block 4, a forming limit seat 5, a sliding seat 6, a sliding space 7, a sliding block 8, a forming punch assembly 9, and a forming die assembly 10.

[0018] The pressure plate is movably connected to the bottom surface of the upper mold assembly via the first elastic element, and the drive wedge is fixedly connected to the bottom of the upper mold assembly.

[0019] In some embodiments of this application, the upper mold module includes an upper template, and a pad is fixedly connected to the bottom surface of the upper template. The driving wedge is fixedly connected to the upper template or the pad.

[0020] In some embodiments of this application, a stop plate is also provided on the top surface of the pressure plate.

[0021] The lower mold assembly is equipped with a material support block to lift the product (material strip) 11 for easy movement. The lifting and shaping block is vertically mounted on one side of the lower mold assembly via a second elastic element. Under the elastic force of the second elastic element, the lifting and shaping block moves upward to reset, thereby lifting the product (material strip). The shaping limit seat is fixedly mounted on the other side of the lower mold assembly. The sliding seat is movably mounted between the lifting and shaping block and the shaping limit seat. One end of the sliding seat is movably connected to the shaping limit seat via a third elastic element 12, so that the sliding seat approaches or contacts the lifting and shaping block under the elastic force of the third elastic element to complete the reset.

[0022] The sliding seat is provided with a sliding space. The sliding block is movably connected to the sliding space through the fourth elastic element 13, so that the sliding block moves and resets in the direction of the shaping and limiting seat under the elastic force of the fourth elastic element. The sliding block near the shaping and limiting seat is provided with a guide slope that contacts the driving wedge, so that the sliding block moves in the direction of lifting the shaping block under the action of the driving wedge.

[0023] A forming die assembly is fixedly connected in the sliding space near the lifting forming block, and a forming relief groove 17 is provided at the bottom of the forming die assembly. A forming punch assembly is fixedly connected on the sliding block facing the forming die, so that the forming punch assembly cooperates with the forming die assembly under the action of the driving wedge and the sliding block to stamp and form the product (material strip).

[0024] In some embodiments of this application, the lower mold module is provided with guide plates 14 that are movably connected to both sides of the sliding seat, and the sliding space is provided with guide plates that are movably connected to both sides of the sliding block. The guide plates can guide the movement of the sliding seat and the sliding block, thereby improving the stability of the movement.

[0025] In some embodiments of this application, a sliding guide plate is provided on the guide slope that contacts the slope of the driving wedge, and an anti-side guide plate is provided on the shaping and limiting seat that is slidably connected to the side wall of the driving wedge.

[0026] In some embodiments of this application, a shaping drive block 15 is fixedly connected to the sliding block, and a shaping drive guide groove 16 is inclinedly provided on the drive wedge. The outer end of the shaping drive block is movably connected to the shaping drive guide groove. When the third elastic element is insufficient or fails, the shaping drive block will drive the sliding block to move outward under the action of the drive wedge to ensure the reset of the sliding block.

[0027] In some embodiments of this application, the top of the lifting and shaping block, the top of the sliding seat near the lifting and shaping block, and the top of the shaping die are provided with contour positioning grooves that cooperate with the product (strip).

[0028] In some embodiments of this application, the shaping die assembly includes a shaping die module, a punching and slotting tool, and a shaping slot, wherein the punching and slotting tool and the shaping slot are disposed on the shaping die module.

[0029] In some embodiments of this application, the shaping punch assembly includes a shaping insert, a punching punch, and a shaping punch body. The punching punch and the shaping punch body are disposed on the shaping insert. The punching punch cooperates with the punching groove to punch the strip, and the shaping groove cooperates with the shaping punch body to shape the strip.

[0030] In some embodiments of this application, the first elastic element, the second elastic element, the third elastic element, and the fourth elastic element can all be nitrogen springs.

[0031] During mold closing, the strip moves along the support block to the target position. At this time, the lifting and shaping block remains in a lifted state under the action of the second elastic element. The upper mold assembly presses down to drive the support block and the product (strip) to descend synchronously, so that the product (strip) is pressed tightly on the lifting and shaping block. The upper mold assembly continues to press down to drive the product (strip) and the lifting and shaping block to descend. At the same time, the drive wedge gradually inserts between the sliding block and the sliding seat, so that while pushing the sliding seat to compress the third elastic element and move towards the shaping limit seat, it pushes the sliding block to move towards the lifting and shaping block. This allows the shaping punch assembly and the shaping die assembly to move relatively closer and cooperate to punch and shape the product (strip). At this time, the concave (convex) structure on the product (strip) is located in the shaping relief groove.

[0032] When the mold opens, the upper mold assembly drives the pressure plate and the drive wedge to rise. The drive wedge gradually rises until it disengages from the sliding block. Under the action of the third elastic element, the sliding seat moves and resets in the direction of lifting the forming block, so that the concave (convex) structure on the product disengages from the forming relief groove. At the same time, under the action of the fourth elastic element, the sliding block drives the forming punch assembly to move and reset in the direction away from the forming die assembly. At this time, the material support seat also drives the product (material strip) to rise under the action of its own spring, thereby realizing the complete separation of the product (material strip) from the entire mold and preventing interference.

[0033] The beneficial effects of this self-adjusting stamping and forming die are as follows: through the synchronous movement of structures such as sliding seats and sliding blocks, the precise coordination between the forming punch assembly and the forming die assembly can be achieved, which not only improves the efficiency of stamping and forming, but also avoids interference between the strip and the die, greatly improving the accuracy and effectiveness of stamping and forming, and increasing the yield of products.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
