Description

Technical Field

[0001] The utility model relates to the technical field of gear grinding machines, and particularly relates to a numerical control gear grinding machine for broaching punches. Background Art

[0002] The broaching punch is mainly used for the hole processing of various plastic thin materials and paper products with a thickness of 0.02 - 1.0 mm, such as drawstring garbage bags, various packaging bags (food, flowers, clothing, etc.), agricultural cultivation mulch films and other products. The diameter of the broaching punch is determined according to the size of the processed hole shape, and the front end is serrated to facilitate piercing and cutting the material.

[0003] The traditional front-end broaching process of the broaching punch is divided into two processes. First, the tooth shape is processed, and then the tooth end edge is processed. The traditional edge processing uses manual grinding, which has low efficiency, unstable yield rate, and is prone to processing defects such as broaching damage, asymmetric edge, and incomplete processing, resulting in scrap products, increasing production costs, and reducing production efficiency. To solve these problems, a general-purpose machining center or a numerical control tool grinding equipment can be used. Due to its multi-degree-of-freedom and high-precision characteristics, it can finely grind the edge to meet the processing requirements. However, the replacement of tooling, grinding wheels, calibration and debugging, etc. are relatively complex operations and have certain requirements for the skills of operators; moreover, the equipment is expensive, resulting in increased production costs.
