Embodiment 1

[0014] The preparation process of the heavy-duty scraper conveyor sprocket includes the following steps:

[0015] a. Integral casting of the sprocket; the sprocket blank obtained by casting is in parts by weight: S, 5-15 parts, C, 10-20 parts, Mn, 5-15 parts, Si, 3-8 parts, Co, 5-8 parts, Cu, 5-10 parts, Ti, 3-8 parts and P, 5-10 parts;

[0016] b. Heat treatment: annealing, quenching, high-temperature tempering and high-frequency quenching of chain sockets are performed sequentially on the cast sprocket blanks to obtain finished products;

[0017] In step a, the sprocket blank obtained by casting contains: S, 10 parts, C, 15 parts, Mn, 10 parts, Si, 6 parts, Co, 7 parts, Cu, 8 parts, Ti, 6 parts and P, 8 copies;

[0018] Annealing refers to heating the sprocket to 860-900°C at a rate of 100-130°C / h and keeping it warm for 12-18 hours, then cooling to 300-400°C with the furnace and then air-cooling to room temperature.

Abstract

The invention discloses a preparation technology of a chain wheel of a heavy scraper conveyer. The preparation technology of the chain wheel of the heavy scraper conveyer is characterized by comprising the following steps that a, inblock casting of the chain wheel is performed, wherein a chain wheel blank obtained through casting comprises, by weight, 5-15 parts of S, 10-20 parts of C, 5-15 partsof Mn, 3-8 parts of Si, 5-8 parts of Co, 5-10 parts of Cu, 3-8 parts of Ti and 5-10 parts of P; and b, heat treatment is performed, specifically, the chain wheel blank obtained through casting is subjected to annealing, quenching, high-temperature tempering and chain nest high-frequency quenching in sequence so as to obtain a finished product. According to the preparation technology of the chain wheel of the heavy scraper conveyer, by changing the material of the chain wheel of the heavy scraper conveyer and changing a heat treatment technology in a matched mode, all the performance of the chain wheel is optimized through the comprehensive measures, and the defects that the tooth surfaces are seriously abraded, edge curling is prone to occurring, and the service time is relatively short are overcome.

Description

technical field [0001] The invention relates to the field of manufacturing mechanical parts, in particular to a preparation process for a sprocket of a heavy-duty scraper conveyor. Background technique [0002] The sprocket of the present invention is the main part of the heavy-duty scraper conveyor transmission equipment, including sprocket teeth and sprocket body. The sprocket is installed on the transmission shaft to drive the chain to rotate. During the process, it is subjected to huge alternating loads and impact loads, resulting in broken teeth and severe wear or failure of the chain nest. [0003] Regardless of the material and preparation process of the existing sprockets, there are basically defects such as poor welding performance, easy wear, broken teeth, curling, low production efficiency, and high manufacturing cost, so they cannot meet market needs. Contents of the invention [0004] The purpose of the present invention is to provide a heavy-duty scraper con...
