Rotary cutting and roll forging machine

Abstract

The invention discloses a rotary cutting and roll forging machine, which comprises a main rotary cutting and roll forging roll and an auxiliary rotary cutting and roll forging roll, wherein the outer side of the main rotary cutting and roll forging roll is provided with a main loose roll; the outer side of the auxiliary rotary cutting and roll forging roll is provided with an auxiliary loose roll; the axis of the main loose roll is parallel to the axis of the main rotary cutting and roll forging roll; the main loose roll is in rolling friction contact with the main rotary cutting and roll forging roll; the axis of the auxiliary loose roll is parallel to the axis of the auxiliary rotary cutting and roll forging roll; the auxiliary loose roll is in rolling friction contact with the auxiliary rotary cutting and roll forging roll; a plane where the axis of the main loose roll and the axis of the main rotary cutting and roll forging roll are positioned is superposed with a plane where flexural deflection force is applied to the main rotary cutting and roll forging roll; a plane where the axis of the auxiliary loose roll and the axis of the auxiliary rotary cutting and roll forging rollis superposed with a plane where flexural deflection force is applied to the auxiliary rotary cutting and roll forging roll; the rigidity of the main loose roll is higher than that of the main rotarycutting and roll forging roll; and the rigidity of the auxiliary loose roll is higher than that of the auxiliary rotary cutting and roll forging roll. According to the invention, the service life of the main rotary cutting and roll forging roll and the auxiliary rotary cutting and roll forging roll is prolonged by 5 times.

Description

Technical field [0001] The invention relates to a grinding ball production device, in particular to a rotary cutting and rolling forging machine that uses heated round steel to continuously produce steel grinding balls. Background technique [0002] It is an indisputable fact that the production of steel grinding balls with rotary cutting and rolling forging machines has high productivity and good benefits. However, the prior art peeling and roll forging machines still have the phenomenon of main peeling, roll forging rolls and auxiliary peeling, and roll forging rolls are easily fatigued and damaged, resulting in main peeling, roll forging rolls and auxiliary peeling, roll forging The roller has short service life and frequent replacement, which relatively affects the further improvement of production efficiency, and the production cost is relatively high. The main rotary cutting, rolling forging rolls and auxiliary rotary cutting, rolling forging rolls are continuously cuttin...
