Special cutter for digital forming machine

Abstract

The invention discloses a cutter and particularly relates to a special cutter for a digital forming machine. The special cutter comprises a cylindrical cutter shank, a cutter body and a cutter bit cutting part, wherein the cutter shank is connected with the cutter body; the cutter bit cutting part is arranged at the front end of the cutter body; the cutter shank, the cutter body and the cutter bit cutting part are integrated into a whole; the cutter bit cutting part is provided with a plurality of cutting edges; and the diameter of each cutting edge is larger than that of a cylinder of the cutter body. The cutter has the advantages that the quality of foam cutting surface is ensured, the characteristics of the digital forming machine of lost foam are favorably met, the cutting machining efficiency is greatly increased, and the cutting machining quality is greatly improved.

Description

technical field [0001] The invention relates to a cutter, in particular to a special cutter for a lost foam digital forming machine. Background technique [0002] At present, most of the lost foam manufacturing equipment of many enterprises use equipment from the 1980s and 1990s. The design of the equipment has serious defects, which are far from meeting the process requirements. Domestic large-scale metal parts adopt foam lost foam manufacturing blanks, which often require manual cutting and bonding. From processing plastic foam, manual bonding models to buried sand lost foam casting, the manufacturing cycle is long and there are many links. It is difficult to control the manufacturing quality, and higher cost. [0003] In view of the urgent need for development of complex metal parts, mold manufacturing technology and equipment, especially in the automobile, shipbuilding, machinery and other enterprises facing the need to speed up new product development and single-piece...
