Multi-station punching machine

Abstract

The invention relates to a multi-station punching machine. The multi-station punching machine comprises a punching machine frame, a power input mechanism and a plurality of punching mechanisms, the punching mechanisms are arranged on the punching machine frame and are in mutual meshing transmission through gears, the power input mechanism is in transmission connection with one punching mechanism,the punching mechanisms conduct different punching machining on workpieces to be machined, each punching mechanism comprises a crankshaft, a connecting rod and an adjusting assembly, a gear is arranged on each crankshaft, each connecting rod is in transmission connection with the corresponding crankshaft, each adjusting assembly is connected to the lower portion of the corresponding connecting rod, and an upper die is connected to the lower portion of each adjusting assembly. Through driving of the single power input mechanism and meshing transmission of the gears among the multiple punching mechanisms, simultaneous operation work of multiple stations is achieved, a product is bent multiple times, the machining efficiency is improved, the occupied space is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of punching machines, in particular to a multi-station punching machine. Background technique [0002] The existing stamping process is generally a set of molds corresponding to a stamping process. For some workpieces, such as iron boxes, metal sheets are formed through multiple processes such as punching, bending, flanging, etc. Each process requires a set of stamping dies. , or replace different stamping dies on the same punching machine, or need multiple punching machines to complete stamping in turn. There are many stamping processes, molds, and equipment occupied. At the same time, the transfer between various processes needs to be adjusted by the height of the stamping die. , It is difficult to ensure that the processing point of the stamping die is at the same position, so the production efficiency is low and the processing cost is high, and the stability of product quality during processing is poor. ...
