Manufacturing method of sugarcane press roll

Abstract

The invention belongs to the technical field of roll shaft manufacture, and provides a manufacturing method of a sugarcane press roll. The sugarcane press roll comprises a roll shell and a roll shaft, the roll shell is tightly fixed on the roll shaft through shrink fit and clearance fit, the roll shell comprises roll teeth, a shell body and a support frame, the shell body of the roll shell is formed by conducting roll forming on a steel plate, the annular support frame is welded to the interior of an inner cavity of the shell body to form a roll shell inner hole, the roll teeth are welded to the outer side face of the shell body, machining is conducted on the roll teeth and the roll shell inner hole, and the roll shaft is sleeved with the roll shell in a shrink fit mode through the roll shell inner hole. According to the manufacturing method of the sugarcane press roll, the prominent problems that for traditional roll shell manufacture, a large number of raw materials are needed, the manufacturing time is long, the processing cost is high, the service life is short, the maintenance is difficult, and the maintenance cost is high are solved; the sugarcane press roll which is short in processing period and low in processing cost is provided for sugar enterprises.

Description

technical field

[0001] The invention belongs to the technical field of roller shaft manufacture, in particular to a method for manufacturing sugarcane press rollers. Background technique

[0002] The sugarcane press machine is used in sugar industry enterprises to extract juice from sugarcane and realize the mechanical equipment of solid-liquid separation. There are multiple rollers on the sugarcane press machine. The rollers include a forged steel mandrel and a cylindrical roller shell cast by pig iron. Several V-shaped teeth are evenly distributed along the circumference of the roller shell, and the V-shaped teeth of adjacent rollers mesh correspondingly. For the processing of press roll shells in the sugarcane sugar industry in my country and the world, the casting blanks are all sand casting and vertical casting.

[0003] The basic process of the pressure roller on the sugarcane press is: casting roll shell - machining of the inner hole of the roll shell - rolling shaft...
