Description

Technical Field

[0001] The utility model relates to the field of stamping dies, in particular to a novel stamping die. Background Art

[0002] A stamping die is a die used for metal stamping processing, also known as a blanking die or a pressing die. Stamping is a processing technology that presses a metal sheet into a specific shape by applying force, and is commonly used in manufacturing products such as automobile parts, electronic device casings, and furniture. Therefore, a novel stamping die is proposed.

[0003] When the existing stamping dies are in use, most of them cannot effectively disassemble the dies quickly. Therefore, when an enterprise's production line needs to switch to other products, it takes a certain amount of time to replace the dies, which to a certain extent affects the work efficiency. At the same time, when the current stamping dies are in use, it may cause a problem of slight deviation during stamping, which may cause a certain quality loss to the products. Therefore, there is an urgent need for technical improvement now. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a novel stamping die is proposed. By setting a rotating block, rotating the rotating block, the rotating block drives the rotating shaft to rotate, the rotating shaft drives the fixed clamping plate to rotate, the fixed clamping plate is aligned and inserted into the installation groove and rotated, so as to fix the upper die. Then, secondary fixation is carried out through the clamping column. When the upper die moves, the slider moves on the rod body of the limiting rod to limit the upper die. Therefore, during stamping, the upper die and the lower die can be better aligned, reducing the production defective rate. At the same time, the upper die and the lower die can be quickly replaced, effectively reducing the time wasted in replacing the die when changing products.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

Thus, through the rotation of the threaded rod 12, the connecting rod 5 is driven to move, so that the connecting rod 5 drives the stabilizing rod 17 to move, and the stabilizing rod 17 is inserted into the stabilizing hole 27 of the lower die 3 to fix the lower die 3. Then rotate the rotating block 24, so that the rotating block 24 drives the rotating shaft 26 to rotate, so that the rotating shaft 26 drives the fixing clamping plate 13 to rotate, so that the fixing clamping plate 13 is aligned and inserted into the inside of the installation groove 22 and rotated, so as to fix the upper die 23. Then, it is secondarily fixed through the clamping column 20. Then, the limiting rod 11 passes through the supporting plate 7 and the slider 21 and is inserted into the hole 18. Then, the plate is placed on the upper end of the lower die 3. Then, start the stamping cylinder 8, and the stamping cylinder 8 drives the upper die 23 to move through the mounting block 19, so as to perform stamping work on it. When the upper die 23 moves, the slider 21 moves on the rod body of the limiting rod 11 to limit the upper die 23. Thus, during stamping, the upper die 23 and the lower die 3 can be better aligned, so as to reduce the production rejection rate.
