Multi-angle side punching die and method for automobile framework part

Abstract

The invention relates to a multi-angle side punching die for an automobile framework part. The die comprises an upper die body and a lower die body, a profiling positioning block is fixed to the lowerdie body, and two movable side pressing blocks and a reset assembly are arranged on the lower die body in a sliding connection manner. A profiling pressure plate and two side cutters are arranged onthe upper die body. Multiple first hydraulic cylinders and multiple mounting grooves are arranged on the lower surfaces of the movable side pressing blocks, side punching puncher pins are arranged atthe output ends of the first hydraulic cylinders, and multiple open holes are formed in the side surfaces of the movable side pressing blocks. Multiple second hydraulic cylinders are arranged in the lower die body, cylinder bodies of the first hydraulic cylinders communicate with cylinder bodies of the second hydraulic cylinders through oil pipes, and a reset piece is arranged on the lower die body. The overall structure is simple and quite compact, the aim of multi-angle synchronous side punching can be achieved, meanwhile, the overall size is very small, the number of the first hydraulic cylinders and the punching directions of the first hydraulic cylinders are very easy to adjust, the upper die body does not need to be additionally and excessively changed no matter how many holes are punched, the applicability of the die is extremely high, and the overall cost is low.

Description

technical field [0001] The invention relates to the technical field of processing dies for automobile skeleton parts, and more specifically, to a multi-angle side punching die and method for automobile skeleton parts. Background technique [0002] Depending on the shape design of automobile skeleton parts, side punching at multiple angles is often required. At present, most of the methods used are to use multiple sets of side cutters with corresponding side punching slider components to carry out side punching processing respectively or use multiple Repeated side punching process, the punching flexibility of the two methods is poor, the overall mold unit volume is relatively large, the complex structure makes the layout design difficult, debugging is very inconvenient, and the former method needs synchronous side punching The more holes there are, the more difficult it is to debug, and the adjustment is also very inconvenient.
