Symmetrical S-shaped flanging die

Abstract

The invention discloses a symmetrical S-shaped flanging die, which comprises an upper die plate, a left convex die, a right convex die and a concave die, wherein the upper die seat is symmetrically provided with a left moving groove and a right moving groove, the left convex die is movably arranged in the left moving groove by a shaft 1, the right convex die is movably arranged in the right moving groove by a shaft 2, the concave die is provided with a left forming groove and a right forming groove, the left side wall of the left forming groove is an inclined edge which is provided with an upper narrow part and a lower wide part, the right side wall of the left forming groove is an inclined edge which is provided with an upper wide part and a lower narrow part, the left side wall and the right side wall of the left forming groove are connected by a semicircular bottom edge, the right forming groove structure and the left forming groove are in a mirror symmetrical way, the left forming groove is matched with the left convex die, and the right forming groove is matched with the right convex die. The symmetrical S-shaped flanging die has the advantage that the S-shaped bending and forming can be completed in a one-time way, and the two times of material return are not needed, so the processing efficiency is high, and the processing performance is high.

Description

technical field [0001] The invention relates to the technical field of cold stamping processing, in particular to a symmetrical S-shaped crimping die. Background technique [0002] The conventional working procedure of the S-shaped hemming workpiece requires two steps, that is, the first bending and forming, and then the second bending and forming. The two processes need to accurately place the workpiece in place, and need to return the material twice, so not only the processing efficiency is low, but also the problem that the deflection or movement of the workpiece is prone to cause the unevenness of the final formed workpiece. Therefore need to design and develop a kind of composite mold that can carry out one-shot forming to the workpiece of S-shaped hemming structure, to overcome the above-mentioned problems. Contents of the invention [0003] The purpose of the present invention is to provide a symmetrical S-shaped crimping die, which can complete the bending and for...

Problems solved by technology

The two processes need to accurately place the workpiece in place, and need to return the material twice, so not only the processing efficiency is low, but also it is easy to cause the workpiece to be skewed or moved, resulting in unevenness after the final forming of the workpiece
