The invention discloses a forming system and technology for an automobile support. The forming system comprises a blanking device, a stretching module, a blanking module and a punching device. The blanking device is used for stamping the plate into a blank required for forming and processing the bracket; the stretching module is used for stretching the blanked blank for multiple times, so that the middle part of the blank is stretched out of a forming part; during stretching, the height of the forming part is greater than that of the required supporting part; meanwhile, the side fillets of the forming parts are reduced in sequence until the fillets are the same as the fillets corresponding to the required supporting parts; the blanking module is suitable for blanking the upper part of the forming part and the side part of the blank, so that the forming part is blanked into the required supporting part; the punching device is suitable for punching the positioning hole and the mounting hole in the blanked blank, and the forming process is carried out through the forming system. The method has the beneficial effects that through multi-step stretching, the forming difficulty of the supporting part in the support can be effectively reduced, and the quality of the formed supporting part can be effectively improved.
Description
technical field [0001] The application relates to the field of auto parts processing, in particular to a molding system for an auto bracket. Background technique [0002] The car bracket is an important part of the car frame, especially the bracket of the car chassis suspension. As a connecting piece between the car frame and the axle, it mainly plays the role of transmitting force or moment. [0003] Such as figure 1 As shown, it is an existing bracket 100 for suspension of an automobile chassis, on which a support portion 110 is provided. The height H of the support portion 110 is generally above 60 mm, and the chamfer R at the bottom of the support portion 110 is generally 8.5 mm. For the processing of the support part 110, the traditional method is basically to directly lock the blanking size to directly stretch and punch out the opening 1100, which can save materials to the greatest extent and make the product, but direct stretching will cause As the height increases,...
