Device for simultaneously flanging front side, left side and right side of automobile front fender

Abstract

The invention discloses a device for simultaneously flanging the front side, the left side and the right side of an automobile front fender. The device comprises a top plate, a bottom plate, a bottomdie, supporting columns, a hydraulic cylinder, a three-stage telescopic rod, a pressing plate, a left plate overturning mechanism, a front plate overturning mechanism, a right plate overturning mechanism, a rotating seat and a connecting rod. The top plate is arranged above the bottom plate in parallel, four supporting columns are symmetrically fixed between the top plate and the bottom plate, anda fender flanging device is driven by a hydraulic cylinder to press downwards. The left plate overturning mechanism, the front plate overturning mechanism and the right plate overturning mechanism are turned over under the guide action of the connecting rods, and the front surface, the left side and the right side of the fender are flanged, so that the traditional processing procedures are reduced, and the processing cost is reduced. Meanwhile, through the elastic stretching and retracting among a first-stage barrel, a second-stage barrel and an ejector rod, the pressing plate makes contact with the fender to be pressed down and fixed firstly, then the front plate overturning mechanism is pressed down and overturned to overturn the front side, and finally the left plate overturning mechanism and the right plate overturning mechanism press down and flange the two sides of the fender, and the hierarchical operation stabilizes the plate overturn.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a device for simultaneously flanging the front, left and right sides of an automobile front fender. Background technique [0002] The fender is the outer panel of the car body that covers the wheels. It is named because the shape and position of the part on the old car body resembles a bird's wing. According to the installation position, it is divided into a front fender and a rear fender. The front fender is installed on the front At the wheel, it is necessary to ensure the maximum limit space when the front wheel rotates and jumps, so the designer will use the "wheel jump diagram" to verify whether the design size of the fender is appropriate according to the selected tire model size. [0003] When producing molds for fenders, generally manufacturers will avoid completing the work of front flanging and simultaneous left and right side flanging in the same sequence. ...

AI Technical Summary

Problems solved by technology

[0003] When producing molds for fenders, general manufacturers will avoid completing the work of front flanging and simultaneous left and right side flanging in the same sequence. Consider that the simultaneous flanging of the front and left and right sides must exist, but the technology for simultaneous flanging is not mature enough
