Description

Automobile storage battery bracket flanging mechanism Technical Field The utility model relates to the technical field of automobile part manufacturing and production, in particular to a flanging mechanism of an automobile storage battery bracket. Background As shown in fig. 1, the three sides of the battery carrier of the vehicle are negative angles and ribs, and in particular, have a pair of opposite negative angles, as shown by negative angles one 1 and two 2 in fig. 1. On a general flanging die, the negative angle I1 and the negative angle II 2 cannot be flanged in sequence, and because the product is a pair of relative negative angles, the workpiece cannot be taken well along the up-down direction and the left-right direction of the die. The product not only has a pair of opposite negative angles, but also has ribs on the side edges, so if the product is to be taken along the front-back direction of the die, the convex hull on the upper surface of the product and the interference positions of the ribs need to be processed separately, but the accuracy and the stability of the product are challenged greatly. In addition to the problem of taking parts caused by the relative negative angle problem, the negative angles one 1 and three 3 or the negative angles two and three 3 cannot be turned up, and as the same problem of taking parts is faced by the two or three, a three-sequence turning-up die is needed in principle, so that the time and the labor are consumed, and the cost is increased.
