Abstract

The invention relates to the technical field of machining, in particular to a material breaking device of a punching machine for round steel workpieces. The material breaking device of the punching machine comprises a base and an upper die cavity arranged above the base, an adjusting seat and a lower die cavity with an inner circular tool are arranged on the base, and the lower die cavity is fixed on the base through locking bolts. A tool is arranged in the upper die cavity. The material breaking device of the punching machine is simple in structure, convenient to operate, high in machining precision, and not prone to causing deformation of workpieces, and when mass processing is carried out, work efficiency can be effectively improved, and labor intensity of workers can be reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a punch cutting device for round steel workpieces. Background technique [0002] With the wide use of round steel materials such as cylindrical pins and rotating shafts in aviation, aerospace, defense and other fields, the technical requirements for machining them are getting higher and higher, especially for the positioning length and dimensional consistency of cylindrical pins and rotating shafts , Processing surface smoothness, etc. have special requirements. The existing technology mostly adopts the cutting machine processing method. Although the round steel has a simple structure, due to the influence of rigidity, self-weight, cutting force, cutting heat, clamping force, centrifugal force and other factors, the cutting machine is not only low in processing accuracy, but also prone to Bamboo shape, triangular shape, conical shape, bending and other mechanical d...
