Abstract

The invention relates to a novel blanking and cutter connecting process. A cutter connecting opening is designed on an arc line of a product R to ensure that the function of a straight plane of the product is complete; the problems of re-cutting, differential cutting and segment difference easily existing in the machining edge of a part are solved, the knife edge is designed to be in an irregular shape, waste can be effectively prevented from jumping out of the lower die, and the safe and efficient production environment is guaranteed; about 0.05 mm of materials are cut off from the R arc line of an original product to form the arc-shaped notch, burrs generated by repeated cutting or sharp corners generated by incomplete cutting at the cutter connecting position are avoided, and the reject ratio of the product caused by too large burrs is reduced.

Description

Technical field [0001] The present invention relates to the field of automatic machining technology, more particularly, to a new type of punching and cutting knife process. Background [0002] In the existing blanking process, if you want to process a rounded rectangular part, for different processing areas, usually use multiple punching knives for processing, and at the junction of two different blanking knives, due to the defects of the process or the aging of the blanking knife, there are usually burrs of the scraper, which seriously affects the use experience, the specific problems are as follows: [0003] as Figure 1 As shown: for the blanking of a rounded rectangular part, the knife connection position is designed on the straight surface of the processed part, due to the difference in the error of the two knives and the accumulation of errors in the process of the knife, this knife connection method will appear on the straight surface of the product parts processing section...
