Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, specifically to a stamping mold for metal connectors. Background Technology
[0002] In fields such as machinery manufacturing, automotive industry, and construction engineering, metal connectors are crucial basic components for fixing, transmitting, or positioning between parts. Their demand is enormous, and they have stringent requirements for dimensional accuracy and structural strength. Currently, the processing of metal connectors mostly employs step-by-step stamping or cutting methods. Traditional step-by-step stamping requires multiple machines to complete punching, forming, bending, and cutting processes separately. This not only results in high equipment investment costs but also leads to low production efficiency due to material transfer between processes. Furthermore, multiple positioning operations can easily generate cumulative errors, making it difficult to guarantee product consistency.
[0003] Based on the above, this utility model proposes a stamping die for metal connectors, which can effectively solve the above problems. Utility Model Content

[0023] A metal connector stamping die includes an upper die assembly and a lower die assembly, wherein:
[0024] The upper mold assembly includes an upper mold base 1, a punch fixing plate 2, and an upper template 3 connected sequentially from top to bottom; the punch fixing plate 2 is fixedly connected from left to right to a plurality of punches that penetrate the upper template 3, including a punch for positioning holes 4, a punch for connecting holes 5, a punch for separating holes 6, a forming punch 7, a bending punch 8, and a cutting punch 9.
[0025] The lower mold assembly includes a lower mold base 10. A base plate 11 is fixedly connected to both sides of the bottom of the lower mold base 10. A first concave mold plate 12 and a second concave mold plate 13 are fixedly connected to the top of the lower mold base 10 from left to right. The first concave mold plate 12 has a positioning punch 14 for the punch positioning punch 4 to pass through, a connecting punch 15, a separating punch 16, and a forming punch 17. The front and rear sides of the second concave mold plate 13 have inclined surfaces 18 that are adapted to the bending punch 8, and the second concave mold plate 13 has a cutting punch 19 for the cutting punch 9 to pass through.
[0026] This invention achieves integrated processing of metal connectors through the cooperation of the upper and lower mold components. The processes of punching positioning holes, punching connecting holes, punching separating holes, forming, bending, and cutting are completed sequentially from left to right. This eliminates the need for multiple mold changes, significantly improving the stamping efficiency of metal connectors while ensuring the positional accuracy between each process and enhancing the stability of product quality.
[0027] Furthermore, in another embodiment, guide plates 20 are fixedly connected to the front and rear sides of the first concave template 12, and positioning components 22 for positioning the feed distance of the steel strip 21 are fixedly connected to the guide plates 20.
[0028] By setting the guide plate 20, the feeding direction of the steel strip 21 can be guided, preventing the steel strip from deviating during the stamping process. The positioning component 22 can accurately position the feeding distance of the steel strip 21, ensuring that the feeding amount of the steel strip is consistent in each stamping.
[0029] Furthermore, in another embodiment, the positioning component 22 includes a bracket 221 fixedly connected to the first concave template 12, a bolt 222 passing through the upper part of the bracket 221, the threaded rod of the bolt 222 passing through the guide plate 20 and fixedly connected to the positioning block 223, and a spring 224 sleeved on the outside of the threaded rod of the bolt 222, the two ends of the spring 224 being fixedly connected to the bracket 221 and the positioning block 223 respectively.
[0030] By setting the positioning component 22, the positioning block 223 of the positioning component 22 can be embedded in the positioning holes (stamped by the punching positioning hole punch 4) on both sides of the steel strip 21 under the action of the spring 224, ensuring that the position of the steel strip 21 is accurate each time it is fed in the mold, ensuring the accuracy of the stamping process and the stability of the product quality, and avoiding processing errors and defects caused by deviations in the feeding position of the steel strip.
[0031] Furthermore, in another embodiment, the lower mold base 10 has a plurality of waste material drop holes 23 that are directly opposite to the positioning punch hole 14, the connecting punch hole 15, the separating punch hole 16, the forming punch hole 17 and the cutting punch hole 19.
[0032] By setting the waste discharge hole 23, the waste generated during the stamping process can be discharged in a timely manner.
[0033] Furthermore, in another embodiment, guide rods 24 are fixedly connected to the four corners of the upper mold base 1, and guide sleeves 25 that cooperate with the guide rods 24 are fixedly connected to the four corners of the lower mold base 10.
[0034] The guide rods 24 at the four corners of the upper die holder 1 are connected to the guide sleeves 25 at the four corners of the lower die holder 10, providing precise guidance for the relative movement of the upper and lower die assemblies. This ensures that the upper and lower die assemblies always maintain the correct relative position during the stamping process, improving the stability and safety of the device operation.
[0035] Furthermore, in another embodiment, limit posts 26 are fixedly connected to the front and rear sides of the upper mold base 1, respectively.
[0036] By setting the limit post 26, the downward distance of the upper mold assembly can be limited, preventing the upper mold assembly from descending excessively and causing damage to the mold.
