Tool for cutting dry ice and cutterhead provided with same

Abstract

The invention provides a tool for cutting dry ice. The tool comprises a tool body. A front tool face, a back tool face and a cutting edge are formed on the tool body. The geometrical parameters of thetool comprise five mark angles: front angle gamma0, back angle alpha0, tool cutting edge inclination lambdas, tool cutting edge angle Kr and end cutting edge angle Kr', and the front angle gamma0 is5-20 degrees and the back angle alpha0 is 5-20 degrees; by selecting reasonable front angle gamma0 and back angle alpha0, the tool for cutting dry ice has a good cutting property, and meanwhile, the risk of tipping of the tool is reduced, the service life of the tool is prolonged, and therefore, the cost of tool loss is reduced. The invention also provides a cutterhead provided with the tool. Stress of the cutterhead cutting dry ice is dispersed to three cutting areas and the cost of tool loss is reduced, so that the cost of dry ice cleaning is further lowered.

Description

technical field [0001] The invention relates to the field of dry ice processing, in particular to a cutter for cutting dry ice and a cutter head equipped with the cutter. Background technique [0002] Dry ice has sublimation characteristics and low temperature characteristics, and can be used in deburring of injection molded parts, mold cleaning and other fields. During deburring or cleaning, dry ice is required in powder form. In order to slow down the sublimation of dry ice, the finished product of dry ice is generally in the form of blocks, so it is necessary to obtain powdered dry ice by cutting dry ice blocks. In the traditional cutting process, the chip will be discarded as waste; in the dry ice cutting process, the chip, that is, the powdered dry ice obtained by cutting, will be the final product. The size and uniformity of the particle size of the powdered dry ice are used to judge the cutting quality. in accordance with. [0003] Dry ice is a difficult-to-machine...

AI Technical Summary

Problems solved by technology

However, the traditional tools used for cutting dry ice have larger rake angles and rear angles, and sharper cutting edges, which may lead to bending stress at the cutting edge, and at the same time make the cutting edge less strong, and the risk of tool chipping is greater; in general, , the tip of the cutting tool is the part with the most difficult working conditions, the cutting force is more concentrated at the tip, and the tip is the place with the highest cutting speed on the cutting edge, which is easy to wear
