Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a quick-change device for stamping dies. Background Technology

[0002] Automotive parts processing is a crucial part of automobile manufacturing, involving the transformation of raw materials into parts that meet design specifications using various processing technologies (such as cutting, stamping, forging, casting, and welding). These parts include engine components, transmission systems, body structural components, and suspension systems. Stamping dies are used in the stamping stage. Stamping dies are important tools for metal processing, primarily used in stamping presses to form, shear, and punch metal sheets. They typically consist of a die holder, upper die, lower die, guide pillars, clamping devices, punches, and dies. They are made of high-strength materials and undergo heat treatment to improve durability and pressure resistance. During the stamping process, dies need to be changed according to different production requirements.

[0003] During mold replacement and installation, it is necessary to ensure that the upper and lower molds are accurately aligned on the stamping machine. However, current operations usually rely on manual support and adjustment, which not only consumes a lot of physical strength but also increases the workload of operators. Furthermore, prolonged manual support can easily lead to mold misalignment, which in turn affects stamping accuracy and product quality. At the same time, manual adjustment is inefficient and may lead to extended replacement time, affecting the overall operating efficiency of the production line.

[0004] Therefore, this utility model provides a quick-change device for stamping dies to solve the above problems. Utility Model Content

[0026] 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.

[0027] This utility model provides a quick-change device for stamping dies, such as... Figures 1-5 As shown, a quick-change device for stamping dies includes an upper plate 1, a support plate 2 fixedly connected to the upper surface of the upper plate 1, a through groove opened on one side of the support plate 2, a support assembly rotatably connected inside the through groove, and guide assemblies fixedly connected to both sides of the lower surface of the upper plate 1.

[0028] The support assembly includes a positive and negative threaded rod 3. Both ends and the middle of the outer surface of the positive and negative threaded rod 3 are rotatably connected to the inside of the through groove. Both sides of the outer surface of the positive and negative threaded rod 3 are threaded with moving blocks 4. The lower surface of the moving blocks 4 is fixedly connected with a cylinder 5. The bottom end of the cylinder 5 is fixedly connected with a mounting plate 6. The upper die base 13 is placed above the mounting plate 6. The cylinder 5 is activated to drive the mounting plate 6 to move upward, so that the upper part of the upper die base 13 is in contact with the lower surface of the upper plate 1. Then the positive and negative threaded rod 3 is rotated to make the upper die base 13 in the correct position, realizing the alignment of the position. There is no need for manual support and adjustment, which reduces the physical consumption of operators and reduces their workload. It can also effectively avoid the misalignment of the upper die base 13 during the fixing process, which can effectively ensure the stamping accuracy and product quality. At the same time, it can be aligned and installed at one time, which can ensure the efficiency of installation and thus ensure the overall operating efficiency of the production line.

[0029] The guide assembly includes a vertical plate 7, the upper surface of which is fixedly connected to one side of the lower surface of the upper plate 1. The lower surface of the vertical plate 7 is hinged to an inclined plate 8. The lower surface of the inclined plate 8 has a groove, and a roller 9 is rotatably connected inside the groove. A spring 10 is fixedly connected to the upper surface of the inclined plate 8. When the cylinder 5 drives the plate 6 to move upward, if the upper mold base 13 is offset, it can be moved to the middle of the two vertical plates 7 under the guidance of the inclined plate 8 and the roller 9 to achieve front-to-back alignment, so as to ensure that the upper mold base 13 and the upper plate 1 can effectively fit together. The spring 10 is a rigid steel spring, which can generate a certain amount of vibration when the upper mold base 13 moves, so as to facilitate the upper mold base 13 to move effectively to the middle.

[0030] A through hole is provided on one side of the vertical plate 7. A connecting bolt 11 is inserted into the through hole. A nut 12 is threaded to one end of the outer surface of the connecting bolt 11. An upper mold base 13 is sleeved on the middle of the outer surface of the connecting bolt 11. The lower surface of the upper mold base 13 overlaps the upper surface of the mounting plate 6. When the upper mold base 13 is in a suitable position, the connecting bolt 11 is passed through the vertical plate 7 and the upper mold base 13 in sequence, and then the nut 12 is threaded to connect, so as to facilitate the fixing of the upper mold base 13.

[0031] A hydraulic rod 14 is fixedly connected to the edge of the lower surface of the upper plate 1. The bottom end of the outer surface of the hydraulic rod 14 is fixedly connected to the base 15. The upper plate 1 is moved down by the hydraulic rod 14, so that the upper mold base 13 and the lower mold base 18 can be closed.

[0032] A slot is provided in the middle of the upper surface of the base 15. A locking block 16 is engaged inside the slot. Limiting blocks 17 are fixedly connected to both sides of the outer surface of the locking block 16. A lower mold base 18 is fixedly connected to the upper surface of the locking block 16. The upper surface of the lower mold base 18 corresponds to the lower surface of the upper mold base 13. The locking block 16 engages with the slot to connect the lower mold base 18 to the base 15. The limiting blocks 17 prevent the lower mold base 18 from rotating on its own.

[0033] Working steps: First, place the upper mold base 13 above the mounting plate 6, start the cylinder 5 to drive the mounting plate 6 to move upward. Next, if the upper mold base 13 is offset, it can be moved to the middle of the two vertical plates 7 under the guidance of the inclined plate 8 and the roller 9, so that the upper part of the upper mold base 13 is in contact with the lower surface of the upper plate 1. Then rotate the positive and negative threaded rod 3 to make the upper mold base 13 in the living position to achieve alignment. Next, use the connecting bolt 11 to pass through the vertical plate 7 and the upper mold base 13 in sequence, and then thread the nut 12 to fix the upper mold base 13. Finally, the locking block 16 is engaged into the slot to connect the lower mold base 18 to the machine base 15. The limiting block 17 prevents the lower mold base 18 from rotating on its own, thus realizing the installation of the lower mold base 18.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
