Abstract

In the market, stamping machine tools are required to have high productivity and good processing quality. The J72-45D punch is a 45-ton automatic punch. The sliding Table of the punch has a width of 1 meter. It is driven by a coaxial double main cam mechanism in working condition. It can realize synchronous processing of twelve jobs. Therefore, the design and processing of the main cam is particularly important. The original technology employed in the processing of the main cam is to process a single cam by a coordinate grinder. It has been difficult to eliminate the phase error of the two cams when they are assembled on the mandrel after the grinding. In the following experiment, by changing the processing technology, the two cams are assembled on the mandrel with complete processing, so as to correct the error and deliver better performance.
