Process for manufacturing fluted disc for roll crusher

Abstract

Disclosed is a process for manufacturing a fluted disc for a roll crusher. The fluted disc is cast with three different materials. Firstly, an inner core of the fluted disc is cast with ZG 40Cr (chromium) metal materials by a mould and comprises an inner hoop, an outer hoop, ribs and teeth; secondly, the inner core of the fluted disc is placed in the middle of the mould, and outer materials A of the fluted disc are cast in the teeth and the outer hoop of the inner core of the fluted disc by a centrifugal casting method; thirdly, outer materials B are also cast in the ribs and the inner hoop of the fluted disc by the centrifugal casting method, wherein the outer materials B are ZGQ235 metal materials; and fourthly, after the casting procedures are completed, a casting is demolded, heat treatment is performed after a die forging is performed at a temperature, and then the finished special fluted disc for the crusher can be manufactured. The manufacturing process is low in production cost and short in production period, the labor intensity of workers is reduced, and the fluted disc for the roll crusher produced by the process is high in strength, long in service life and can be used for crushing various blocky materials.

Description

technical field [0001] The invention relates to a manufacturing process of a toothed disc of a roller crusher, in particular to a manufacturing process of a toothed disc installed on a roller crusher, and belongs to the technical field of mechanical component manufacturing. Background technique [0002] Roller crusher, especially super large multi-stage roller crusher is a kind of mechanical equipment specially used for crushing bulk coal, coke, silicate, clay, limestone, ore, ceramics, gypsum and other materials. The rollers used in the roller crusher are composed of several metal toothed discs with teeth. The manufacturing technology of the toothed disc is directly related to the quality issues such as the impact strength, hardness and wear resistance of the crusher roller. The existing toothed discs of crushers are generally casted by traditional methods through molds. The preparation process is unreasonable, the production cost is high, the labor intensity of the operat...

AI Technical Summary

Problems solved by technology

The existing toothed discs of crushers are generally casted by traditional methods through molds. The preparation process is unreasonable, the production cost is high, the labor intensity of the operators is high, the production cycle is long, and the produced toothed discs are not strong enough and wear-resistant. Performance and impact resistance are poor. In the long-term impact and grinding work with hard materials, the tooth disc is very easy to be damaged. Frequent replacement of the tooth disc will not only increase the production cost and economic burden of the enterprise, but also often stop the machine for repairing the rollers. Maintenance will also greatly affect the production efficiency of enterprises and bring certain economic losses to users.
