Abstract

The invention discloses a side flanging die for an outer board of a rear cover of a car. A flanging line of the side flange of the outer board of the rear cover of the car is a curved line. The side flanging die comprises an upper die body and a lower die body. A side flanging driving mechanism is disposed on the bottom of the upper die body. A side flanging die insert is fixedly connected with the end of the side flanging driving mechanism. A punch return mechanism body and a side flanging punch insert are disposed on the surface of the lower die body. The side flanging punch insert is fixed onto the punch return mechanism body. A side flanging movable swaging core is disposed in the groove of the side flanging punch insert. By the technical scheme, the state of swaging can be guaranteed in the process of side flanging, the wrinkle of the side flanging can be eliminated. The side flanging die is compact in structure, space-saving, low in cost, convenient in processing and debugging, and simplifies the die structure.

Description

technical field [0001] The invention belongs to the technical field of pressure processing equipment, and relates to a mold structure for plate forming processing, and more specifically, the invention relates to a side flanging mold for an outer panel of an automobile rear cover. Background technique [0002] The shape of the outer panel of the rear cover of some models has a negative angle in the direction of the vehicle body, which requires side flanging of the outer panel of the rear cover. At the same time, due to the shape of the vehicle body, the flange line is an arc, such as figure 1 and figure 2 shown. [0003] The flanging structure of the side flanging mold of the automobile back cover outer plate in the prior art is as image 3 As shown, the structure includes a rollover driving mechanism 2, a rollover die insert 3, a punch return mechanism body 5, and a rollover punch insert 9; the rollover die insert 3 is fixed on the rollover The side drive mechanism 2; th...
