[0003] The prior art has developed some bending devices for vehicle sheet metal processing, for example, the Chinese patent with publication number "CN218134188U" discloses a bending device for sheet metal processing. Compared with the existing auxiliary device for sheet metal processing bending, the bending device for sheet metal processing is equipped with anti-slip soft pads. The design of anti-slip soft pads can increase the stability of sheet metal during bending, reduce the probability of sheet metal falling off during bending, and solve the problem that the existing bending device for sheet metal processing often increases the difficulty of workers during processing due to insufficient stability during processing of sheet metal.

Therefore, the thick sheet metal cannot be effectively processed. UTILITY MODEL CONTENTS

[0005] In view of the problems mentioned in the background technology, the utility model aims to provide a bending device for vehicle sheet metal processing to solve the problem of bending of vehicle sheet metal processing.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] First, the worker needs to effectively place the vehicle sheet metal parts to be processed onto the upper end of the bending body. When placing them, the worker needs to align the two sides of the vehicle sheet metal with the inner side of the limiting plate. Then, the worker can start the hydraulic cylinder. After starting, the output shaft of the hydraulic cylinder will push the upper pressure plate. In this way, the upper pressure plate will clamp the vehicle sheet metal placed on the upper end of the bending body to prevent the sheet metal from shifting during bending. When the upper pressure plate moves down, the rectangular openings on both sides inside the upper pressure plate will slide on the outer ring of the limiting plate. Finally, the worker will start the electric push rod to push the push plate, which will push the vehicle sheet metal. In this way, the vehicle sheet metal will be bent under the pressure, which can effectively play the bending role.

[0017] Secondly, the movable plate hinged to one side of the upper pressure plate will be pushed to effectively bend and form, improving the speed of forming and providing a better working environment for the staff. When the upper pressure plate moves up and down, the springs and telescopic rods fixedly installed around the lower pressure plate will retract, providing a better limiting effect for the upper pressure plate. The positioning rod fixedly installed on the outer ring of the electric push rod can effectively prevent the electric push rod from deviating when pushed, and effectively fix the electric push rod inside the rectangular groove.
