Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a positioning device for continuous stamping dies. Background Technology
[0002] The basic principle of progressive stamping dies is to continuously stamp and form metal sheets using a punch press to manufacture products. It consists of an upper die and a lower die. The upper die is fixed to the top of the punch press, and the lower die is fixed to the bottom. Under the action of the punch press, the upper and lower dies close together, and the metal sheet is stamped and stretched by the die to ultimately become a product of the desired shape.
[0003] Since existing continuous stamping dies lack an effective positioning structure, the accurate position of the lower die during installation cannot be guaranteed. Manually moving the lower die for position adjustment is time-consuming and labor-intensive, increasing the workload of workers. Therefore, a continuous stamping die positioning device is needed to solve the above problems. Utility Model Content

[0015] 1. This continuous stamping die positioning device is equipped with a positioning clamping assembly. By rotating the No. 1 handle, the No. 1 screw can be effectively rotated, thereby enabling the strip lifting plate and the boss to move downwards along the vertical direction of the No. 1 screw. During the downward movement of the strip lifting plate, the L-shaped positioning plate and the lower die can be driven to descend synchronously through the U-shaped connecting frame. The descent of the lower die stops when it descends between the two positioning guide bars and is directly above the positioning boss.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 A continuous stamping die positioning device includes a base plate 1 for mounting a lower die. The upper surface of the base plate 1 has grooves 101 at both ends. The bottom surface of the grooves 101 has strip grooves 102 on both sides. The base plate 1 is provided with a positioning clamping assembly 5 through the strip grooves 102. The upper surface of the base plate 1 has positioning protrusions 3 at the middle of both sides. The lower die has positioning holes that cooperate with the positioning protrusions 3.
[0025] The positioning and clamping assembly 5 includes a strip lifting plate 501, a boss 502 and an L-shaped positioning plate 506. The strip lifting plate 501 is located below the base plate 1, the boss 502 is located at the center of the upper surface of the strip lifting plate 501, and there are two L-shaped positioning plates 506, which are respectively located in two grooves 101.
[0026] The positioning and clamping assembly 5 includes a first screw 503, a U-shaped connecting frame 505, and a second screw 507. The strip-shaped lifting plate 501 and the boss 502 are threadedly connected to the first screw 503. The upper end of the first screw 503 is rotatably connected to the base plate 1 via a bearing. A first handle 504 is provided at the lower end of the first screw 503. Two U-shaped connecting frames 505 are provided, each slidably mounted on both ends of the upper surface of the strip-shaped lifting plate 501. The upper end passes through the strip groove 102 and is connected to two L-shaped positioning plates 506 respectively. By rotating the first handle 504, the first screw 503 can be effectively rotated, thereby enabling the strip lifting plate 501 and the boss 502 to move up and down along the vertical direction of the first screw 503. During the upward movement of the strip lifting plate 501, the L-shaped positioning plate 506 can be lifted by the U-shaped connecting frame 505. During the downward movement of the strip lifting plate 501, the L-shaped positioning plate 506 can be lowered into the groove 101 by the U-shaped connecting frame 505.
[0027] The second screw 507 is rotatably mounted on the front of the boss 502. A second handle 509 is located at the end of the second screw 507 away from the boss 502. A connecting seat 508 is threaded onto the second screw 507. Push-pull rods 510 are rotatably connected to both sides of the connecting seat 508 via limit shafts. The end of the push-pull rod 510 away from the connecting seat 508 is rotatably connected to the U-shaped connecting frame 505. The push-pull rods 510 are rotatably connected to both sides of the connecting seat 508 via limit shafts. The end of the pull rod 510 away from the connecting seat 508 is rotatably connected to the U-shaped connecting frame 505. By rotating the second handle 509, the second screw 507 can be effectively rotated, which can make the connecting seat 508 move back and forth along the second screw 507. When the connecting seat 508 moves forward, the two L-shaped positioning plates 506 can be pushed away from each other by the push-pull rod 510. When the connecting seat 508 moves backward, the two L-shaped positioning plates 506 can be pulled closer to each other by the push-pull rod 510.
[0028] The base plate 1 has positioning guide strips 2 on both sides of its upper surface and outside the positioning protrusions 3. The upper inner side of the positioning guide strip 2 is arc-shaped and the height of the positioning guide strip 2 is higher than the height of the positioning protrusions 3. The positioning guide strip 2 can effectively limit and guide the lower mold. When the lower mold is between the two positioning guide strips 2, the front and rear positions of the lower mold are accurate.
[0029] Among them, the bottom surface of the base plate 1 is provided with limit guide rods 4 at both ends, and the strip lifting plate 501 is provided with through holes at both ends. The lower end of the limit guide rod 4 passes through the through holes and slides with the strip lifting plate 501. By providing the limit guide rod 4, the strip lifting plate 501 can be effectively limited and guided.
[0030] The working principle is as follows: Initially, the distance between the two L-shaped positioning plates 506 is adjusted so that the two L-shaped positioning plates 506 are in a lifted state, with the height of the L-shaped positioning plates 506 being higher than the height of the positioning guide strips 2. Then, the lower mold is placed on the two L-shaped positioning plates 506. By rotating the first handle 504, the first screw 503 can be effectively rotated, thereby enabling the strip lifting plate 501 and the boss 502 to move downwards in the vertical direction along the first screw 503. During the downward movement of the strip lifting plate 501, the L-shaped positioning plates 506 and the lower mold can be driven to descend synchronously through the U-shaped connecting frame 505. The descent of the lower mold stops when it descends between the two positioning guide strips 2 and is directly above the positioning boss 3. The positioning guide strips 2 can effectively limit and guide the lower mold, ensuring accurate front and rear positions of the lower mold when it is between the two positioning guide strips 2.
[0031] Furthermore, after the front and rear positions of the lower mold are adjusted, rotating the second handle 509 can effectively drive the second screw 507 to rotate, allowing the connecting seat 508 to move backward along the second screw 507. During the backward movement of the connecting seat 508, the two L-shaped positioning plates 506 can be pulled closer to each other by the push-pull rod 510, further clamping the lower mold and ensuring that the left and right positions of the lower mold are correct. Finally, rotating the first handle 504 adjusts the clamped and centered lower mold to continue moving downward, and the positioning protrusion 3 can be inserted into the positioning hole of the lower mold to ensure the accurate position of the lower mold. The overall operation is simple, time-saving and labor-saving.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
