Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware processing technology, and in particular to a precision hardware stamping die. Background Technology
[0002] Metal stamping is a process that uses a press and molds to deform or break sheet metal or irregularly shaped profiles such as stainless steel and iron to achieve a certain shape and size. This process is mainly used to plastically deform raw materials such as metal sheets and strips to obtain metal products of the required shape and size.
[0003] A search revealed that patent document CN215090027U discloses a precision metal stamping die. This die is driven by a motor to rotate a gear, which in turn causes the toothed part to move laterally relative to the connecting plate, thus moving the fixed plate and separating it from the lower die. Another lower die is then inserted. The motor then drives the output end to rotate in the opposite direction, causing the gear to rotate and again causing the toothed part to move laterally relative to the connecting plate, bringing the fixed plate into contact with and fixing the lower die. This allows for easy replacement of the lower die in a precision metal stamping die, avoiding the need for different stamping equipment for different metals, reducing production costs, and making the die more convenient and flexible to use.
[0004] The above-mentioned method still has some drawbacks in actual use. After the two motors drive the two sets of sliding rods and the fixed plate to move relative to each other, the two sides of the lower mold are clamped. However, the limitation of the front and rear position cannot be met. Therefore, the pressure generated by the upper mold of the press during the stamping process can easily cause the lower mold to move back and forth under long-term action. Utility Model Content

By setting bolts, the sliding sleeves are fixed on the guide tubes, thereby fixing the position of the shaft.
[0009] Preferably, the rotating mechanism includes four arc-shaped rods, a shaft is rotatably connected to the outer wall of the sliding sleeve, one end of two shafts is fixedly connected to the same rotating rod, a pressing block is fixedly connected to the outer wall of the rotating rod, the bottom of the four rotating rods is fixedly connected to the top of the four arc-shaped rods respectively, a bearing is fixedly sleeved on the outer wall of the shaft, and the outer ring of the bearing is fixedly connected to the outer wall of the sliding sleeve to assist the shaft in stable rotation.
[0010] Preferably, the top of the press is provided with a sliding hole, the inner wall of which is slidably connected to the outer wall of the output end of the first cylinder. The first cylinder drives the upper die to move down to press the raw material in the upper die.
[0011] Preferably, the bottom of the bolt is slidably connected to the inner wall of the limiting hole.
[0012] Preferably, the rectangular plate is located between the four arc-shaped rods, and the rectangular plate drives the four arc-shaped rods to rotate.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Depend on Figures 1-4 As shown, a precision metal stamping die is disclosed, including a press 1. A first cylinder 2 is fixedly connected to the top of the press 1. A sliding hole is opened on the top of the press 1. The inner wall of the sliding hole is slidably connected to the outer wall of the output end of the first cylinder 2. An upper die 3 is fixedly connected to the bottom of the output end of the first cylinder 2. The operation of the first cylinder 2 drives the upper die 3 to move down and contact the lower die 5 to realize the stamping process.
[0023] The press 1 has a hollow worktable 4 fixedly connected inside. The top of the worktable 4 is fixedly connected to a lower mold 5, which supports the lower mold 5. The press 1 also has a second cylinder 6 fixedly connected inside. The top of the output end of the second cylinder 6 is fixedly connected to a rectangular plate 7, which drives the rectangular plate 7 to move up and down. The top of the worktable 4 has four sliding grooves 8.
[0024] The sliding groove 8 is equipped with an adjustment mechanism, which includes eight sliding sleeves 11. Two guide tubes 9 are fixedly connected to the inner walls of the four sliding grooves 8. Multiple limiting holes 10 are evenly opened on the outer walls of the guide tubes 9. The outer walls of the eight guide tubes 9 are slidably connected to the inner walls of the eight sliding sleeves 11 respectively. The guide tubes 9 assist the sliding sleeves 11 in linear movement. The outer walls of the sliding sleeves 11 are provided with threaded holes. Bolts 12 are threadedly connected to the inner walls of the threaded holes. The bottom of the bolts 12 is slidably connected to the inner walls of the limiting holes 10. The bolts 12 fix the position between the sliding sleeves 11 and the guide tubes 9, and the fixed position of the sliding sleeves 11 can be adjusted through the multiple limiting holes 10.
[0025] The slide 8 is equipped with a rotating mechanism, which includes four arc-shaped rods 16. The outer wall of the slide sleeve 11 is rotatably connected to a shaft 13. One end of each shaft 13 is fixedly connected to the same rotating rod 14. The rotating rod 14 rotates through the shaft 13 and moves through the slide sleeve 11. The outer wall of the rotating rod 14 is fixedly connected to an extrusion block 15. The four extrusion blocks 15 are pressed against the outer wall of the lower mold 5 to limit the sides and front and back of the lower mold 5, ensuring its stability and facilitating replacement. The bottom of the four rotating rods 14 is fixedly connected to the top of the four arc-shaped rods 16 respectively. The rectangular plate 7 is located between the four arc-shaped rods 16.
[0026] Working principle: When the lower mold 5 is limited, the second cylinder 6 rotates, causing the rectangular plate 7 to move downward. After moving downward, the rectangular plate 7 contacts the outer wall of the four arc rods 16. The rectangular plate 7 continues to move downward, causing the four arc rods 16 to rotate outward. The outward rotation of the four arc rods 16 causes the four rotating rods 14 to rotate inward through multiple shafts 13. The rotation of the four rotating rods 14 causes the four extrusion blocks 15 to press against the outer wall of the lower mold 5, thus fixing the position of the lower mold 5. At the same time, when fixing the position of lower molds 5 of different sizes, the bolts 12 on the sliding sleeve 11 are rotated so that its bottom slides out of the limiting hole 10, releasing the position fixation between the sliding sleeve 11 and the guide tube 9. The sliding sleeve 11 moves on the guide tube 9, adjusting the position of the rotating rods 14 and changing the distance between them and the lower mold 5, so as to facilitate the position fixation of lower molds 5 of different sizes and increase applicability.
