Abstract

The invention provides a flanging and bending device. According to the flanging and bending device, a plurality of grooves matched with material pressing plates are arranged in the left end of the bottom face of a seat from front to back, each material pressing plate is installed in one groove, a plurality of combined grooves are arranged in the left end of the top face of the base seat from front to back, each combined groove communicates with one groove, each position-limiting bolt is installed in one combined groove, a first arc-shaped groove communicating with all the multiple grooves is arranged in the middle of the bottom face of the base seat, one reset mechanism is installed in each first cylindrical groove, and each reset mechanism abuts against the right end of a rolling shaft mechanism after penetrating through a guide sleeve. The flanging and bending device is simple in structure, convenient to operate and extremely small in use space, is not limited by the flanging length and the flanging amount, avoids the disadvantage of side integral wedge large space occupation and simplifies a process form of flanging with negative angles.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, in particular to a flanging and bending device. Background technique [0002] In the process of designing and manufacturing stamping dies for automobile body panels, most of the parts have rollovers. We usually use rollover mechanisms or non-standard mechanisms to realize the work content of rollovers, but when the length of the rollover is too large ( This problem focuses on "Ji"-shaped parts and inverted "U"-shaped parts), the non-standard mechanism has a large span, resulting in unstable force, easy wear of the guide plate, and the most important thing is that it occupies a lot of space and wastes costs and resources. phenomenon, and when the amount of flanging is too large, it is not easy to control the springback and curling of the workpiece after flanging, which brings great troubles to subsequent debugging. Contents of the invention [0003] In view of this, the present invention ...
