Double-layer die changing system of door cover edge-wrapping press

Abstract

The invention belongs to the technical field of double-layer die changing, and particularly relates to a double-layer die changing system of a door cover edge-wrapping press. The double-layer die changing system comprises a frame fixing device, an electrical control system and a hydraulic pump station, wherein a die lifting device is installed in the frame fixing device, the die lifting device isconnected with the hydraulic pump station, the frame fixing device is connected with four die storage location devices, and the four die storage location devices are correspondingly positioned on theupper left, the lower left, the upper right and the lower right portions of the frame fixing device. The two die storage location devices on the left side are symmetrical to the two die storage location devices on the right side, the die storage location devices are connected with die backing plates, a backing plate storage location device is connected to the left side of the frame fixing device,the backing plate storage location device is positioned between the upper and lower die storage location devices on the left side, a longitudinal push-pull device is connected below the frame fixing device, and the frame fixing device is connected with a transition device connected with the press.

Description

technical field [0001] The invention belongs to the technical field of double-layer mold change, and in particular relates to a double-layer mold change system of a door cover edge wrapping press. Background technique [0002] The four doors and two covers of the car include the left and right front doors, rear doors, engine cover and trunk cover (back door), which are important parts of the car body assembly; The inner and outer panels of the door or the front and rear covers of the car are bonded together by bending. Generally, the car door cover edge wrapping press is equipped with one or two sets of molds, each pair of molds is composed of upper and lower molds, and the molds are placed on the mold changing platform. Since the molds of the hemming press are relatively heavy, generally weighing up to 12-16 tons, it is necessary to equip the press with an automatic or manual mold changing device. Moreover, in order to make full use of the press, it is necessary for the p...

Problems solved by technology

Judging from the actual situation on site, generally, the die change mechanism equipped with one press can automatically change four sets of dies. Add more stations near the press to store molds, so that the space around the press is completely occupied by the mold changing mechanism, and there is no space to store enough material racks, which affects the efficiency of pressing parts and reduces the production cycle. With the increase of stations, the moving distance of the mold becomes longer, and the mold change time also becomes longer, which seriously affects the efficiency of mold change

How to configure more molds for a single press in a limited space without prolonging the mold change time and improving the efficiency of mold change is a major problem faced by the existing automatic mold change mechanism
