Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically a stamping die with high material utilization rate. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] Existing stamping dies are used for continuous mass production. The layout of the stamping die must be based on the size of the material to maximize material utilization. However, while achieving high utilization, the space between the components will be reduced. Therefore, during continuous production, the material may be stretched and deformed, resulting in increased material damage. To address this, we propose a stamping die with high material utilization.

[0014] 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.

[0015] Please see Figures 1-3 This utility model provides a technical solution: a stamping die with high material utilization rate, including a working plate 1, a support platform 2 fixedly installed at the bottom of the working plate 1, a lower fixed die body 3 fixedly installed at the top of the working plate 1, a stamping mechanism 4 for stamping is provided at the top of the working plate 1 and at the position corresponding to the lower fixed die body 3, a uniform feeding mechanism 5 for stable material conveying is fixedly connected to the top of the working plate 1 and on both sides of the lower fixed die body 3, and a stamping position positioning mechanism 6 is provided on the stamping mechanism 4 to prevent excessive material pulling and displacement.

[0016] The lower fixed mold body 3 and the stamping mechanism 4 work together to stamp and form the material. The uniform feeding mechanism 5 then drives the material forward evenly and makes full contact with the stamped material to move it forward, preventing the stamped material from breaking due to the presence of holes. The stamping position positioning mechanism 6, which is set after the scrap is pulled, can prevent the material from being misaligned with the stamping mechanism 4 due to excessive pulling.

[0017] Please see Figure 1 and Figure 2 The stamping mechanism 4 includes a fixed frame 7, a first drive cylinder 8, an upper stamping die body 9, a limiting sleeve 10, and a limiting rod 11. The first drive cylinder 8 is fixedly installed on the top of the fixed frame 7. The output end of the first drive cylinder 8 is fixedly connected to the upper stamping die body 9. Multiple sets of limiting sleeves 10 are fixedly installed on the top of the fixed frame 7. The limiting rod 11 is fixedly installed inside the limiting sleeve 10. The bottom of the limiting rod 11 is fixedly connected to the upper stamping die body 9.

[0018] When it is necessary to stamp the material, the first drive cylinder 8 drives the upper stamping die body 9 to descend and contact the lower fixed die body 3 to stamp the material. When the upper stamping die body 9 descends, it can be limited by the limiting sleeve 10 and the limiting rod 11 to ensure that the upper stamping die body 9 and the lower fixed die body 3 are fully coordinated.

[0019] Please see Figures 1-3 The uniform feeding mechanism 5 includes a fixed plate 15, an active conveying roller 16, a driven conveying roller 17, and a drive motor 18. Two sets of fixed plates 15 are fixedly installed on the top of the working plate 1 and on both sides of the working plate 1. The active conveying roller 16 and the driven conveying roller 17 are rotatably connected between the fixed plates 15. The drive motor 18 is fixedly installed on the fixed plate 15 on one side of the working plate 1. The output end of the drive motor 18 is fixedly connected to the active conveying roller 16. The uniform feeding mechanism 5 also includes a first sprocket 19, a second sprocket 20, and a connecting chain 21. One end of the two sets of active conveying rollers 16 is fixedly connected to the first sprocket 19 and the second sprocket 20, respectively. The connecting chain 21 is provided on the outside of the first sprocket 19 and the second sprocket 20.

[0020] The material to be stamped can be placed between the active conveyor roller 16 and the driven conveyor roller 17. Then, the drive motor 18 drives the active conveyor roller 16 to rotate, so that the active conveyor roller 16 and the driven conveyor roller 17 can make full contact with the material and pull the material forward. The active conveyor roller 16 connected to the drive motor 18 can drive another set of second sprockets 20 and another set of active conveyor rollers 16 to rotate through the first sprocket 19 and the connecting chain 21, so as to complete the uniform feeding of the material.

[0021] Please see Figures 1-3 The stamping position positioning mechanism 6 includes a second drive cylinder 12, a hidden groove 13, and a positioning ring 14. A hidden groove 13 is provided on one side of the bottom of the upper stamping die body 9. A second drive cylinder 12 is fixedly installed on the top of the upper stamping die body 9 at the position corresponding to the hidden groove 13. The output end of the second drive cylinder 12 is fixedly connected to the positioning ring 14. The curvature of the positioning ring 14 is the same as the curvature of the side of the forming material inside the lower fixed die body 3.

[0022] After the upper stamping die body 9 and the lower fixed die body 3 separate from each other, the uniform feeding mechanism 5 operates, and then the second drive cylinder 12 drives the positioning ring 14 away from the interior of the hidden groove 13. This allows the positioning ring 14 to contact the scrap side after the hole is opened, preventing the scrap from being pulled and causing excessive pulling of subsequent materials, thus ensuring more accurate subsequent stamping positions.

[0023] Please see Figure 1 and Figure 2The top of the working plate 1 and both sides of the lower fixed mold body 3 are provided with a guide protection block 22 with one side arc-shaped. The guide protection block 22 with one side arc-shaped can prevent the material from being scratched when it is loose and pulled.

[0024] In use, firstly, the lower fixed mold body 3 and the stamping mechanism 4 cooperate to stamp the material. Then, the uniform feeding mechanism 5 drives the material forward evenly and ensures complete contact with the stamped material, preventing breakage due to holes. After the scrap is pulled, the stamping position positioning mechanism 6 prevents misalignment between the material and the stamping mechanism 4 due to excessive pulling. When stamping is required, the first drive cylinder 8 lowers the upper stamping mold body 9 to contact the lower fixed mold body 3 for material stamping. During the descent of the upper stamping mold body 9, the limiting sleeve 10 and the limiting rod 11 provide limiting, ensuring complete cooperation between the upper stamping mold body 9 and the lower fixed mold body 3 for stamping. The material can be placed between the active conveying roller 16 and the driven conveying roller 17. Then, the drive motor 18 drives the active conveying roller 16 to rotate, so that the active conveying roller 16 and the driven conveying roller 17 can fully contact the material and pull the material forward. The active conveying roller 16 connected to the drive motor 18 can drive another set of second sprockets 20 and another set of active conveying rollers 16 to rotate through the first sprocket 19 and the connecting chain 21. This can complete the uniform feeding of the material. After the upper stamping die body 9 and the lower fixed die body 3 are separated, the uniform feeding mechanism 5 operates. Then, the second drive cylinder 12 drives the positioning ring 14 away from the inside of the hidden groove 13. This allows the positioning ring 14 to contact the scrap side after the hole is opened, preventing the scrap from being pulled and causing excessive pulling of subsequent materials, and ensuring more accurate subsequent stamping positions.

[0025] 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.
