Description

Technical Field

[0001] The utility model relates to the technical field of fender processing, in particular to a stamping die for fender processing. Background Art

[0002] With the continuous development of the automobile industry, the processing technology of fenders is also constantly improving. The fender is the part above the tire, between the door, hood and bumper, also known as the fender, which can be divided into front fenders and rear fenders. Its function is to use fluid mechanics to reduce the drag coefficient and make the car run more smoothly. In the processing of the fender, a stamping die is needed.

[0003] The utility model with publication number CN219648484U provides a stamping die for automobile side panel processing, including a support plate, a driving assembly, a support rod, an adjusting block, a telescopic member, an elastic component, an adjusting assembly, a placement seat and a pressing block. When the side panel is stamped, the side panel is placed on the placement seat, and the installed adjusting assembly drives the adjusting block connected thereto to move, and the adjusting block drives the side panel placed on the placement seat to move to one side of the punch, and the installed driving assembly drives the transmission assembly to operate, and the transmission assembly drives the connecting plate on one side to move toward the side close to the side panel. During this process, the installed pressing plate first contacts the side panel, and as the connecting plate continues to be pressed down, the elastic component generates elastic force to make the pressing plate press the side panel, thereby improving the stability of the side panel during stamping. After the stamping is completed, the transmission assembly drives the punch away from the side panel, and through cooperation with the adjusting assembly, drives the side panel away from the punch, which is convenient for removing and replacing the side panel, thereby improving the practicality of the device.

[0004] When in use, it is inconvenient to position the fender and it is difficult to place the fender in a correct stamping position, which results in low loading efficiency of the fender and affects the stamping efficiency.
