Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to a stamping and flanging mold with an automatic material pushing mechanism. Background Art

[0002] At present, in the production process of small manual line stamping flanging dies, the operator uses a magnetic clamp to adsorb the blank and place it in the flanging die. After the upper slider of the press moves downward to complete the flanging of the blank, the worker uses a magnetic clamp to adsorb the flanging-completed parts from the die and place them in the tool, thus completing one stamping cycle and starting the next stamping cycle.

[0003] When flanging is performed using a normal stamping and flanging die, the blank is stamped and the part is contained inside the stamping die, requiring the operator to use a magnetic clamp to remove it. If the stamping material is aluminum, copper or other materials, an open clamp is required to remove the material, and the clamping part of the part requires an avoidance groove to be opened on the corresponding surface to ensure that the clamp can remove the material smoothly. Although this solves the problem of material removal, the avoidance groove position is likely to form an indentation on the surface of the part during the stamping process, affecting the quality of the part. At the same time, in the process of clamping the part, it is easy for the part to fall off due to the collision with the die or unstable clamping.

[0004] In addition, since the feeding and retrieving processes are all done manually, not only is the production efficiency low, but there are certain risks for operators, so there is a lot of room for improvement. Summary of the invention
