Problems solved by technology

[0002] In the existing watch case blank production process, due to the traditional operating habits of the existing process, only the plate with straight-line blanking is processed, which cannot deal with plates with special sizes and specifications, and the remaining corners are large, resulting in a lot of waste. In view of the above problems , the present invention provides a new stamping process, due to the reduction in the number of blanking processes, low cost, improved production efficiency; improved material utilization, reduced corner waste, and good economic benefits due to the high price of watch case materials

Abstract

The invention relates to a watchcase blank manufacturing technology, and belongs to the technical field of watch manufacturing technologies. The circumferential-shaped arrangement is adopted, blank 1 and blank 3 are longitudinally arranged, blank 2 and blank 4 are transversely arranged, and second specification lump materials are placed on a punching die positioning plate and are machined in sequence; or the blank 1 is stamped first and then is horizontally rotated by 180 degrees, the blank 3 is stamped, lump materials are horizontally rotated by 90 degrees, the blank 2 is stamped, rotating by 180 degrees is achieved again, and the blank 4 is stamped. The material utilization rate is improved, corner waste materials are reduced, and due to the fact that watchcase materials are high in cost, good economic benefits can be achieved.
