Method for manufacturing compact flat vertical chain ring

Abstract

The invention relates to a method for producing compact plat chain upright ring used in scrape plate transmitter, wherein it comprises making the chain steel into rod, heating rod to 630-730Deg. C, feeding rod into chain weaver, bending into chain ring, feeding rod into welding machine, removing burr, putting it above the mould of compressor, inserting the corn blank into the chain ring, functioning. The invention can improve mechanical property and reduce cost.

Description

technical field [0001] The invention relates to a manufacturing method of a compact flat chain vertical ring which is often used in scraper conveyors. Background technique [0002] As the main component of the scraper conveyor, the chain is also a wearing part, and the consumption is very large. Due to the wide distribution of thin coal seams, abundant reserves and diverse geological conditions in my country, the thickness of coal seams is generally 0.5 to 2.3 m, of which thinner coal seams of 1.2 to 2.3 m occupy a larger proportion of coal fields in my country. Constrained by the space, it is necessary to design a high-yield, high-efficiency and high-reliability working face scraper conveyor equipment that meets the requirements of the coal mining process in thin coal seams with a height of 1.2-2.3m. [0003] In order to adapt to the changes of the scraper conveyor, it is necessary to design and use a compact flat chain to strengthen the mechanical properties of the chain,...

AI Technical Summary

Problems solved by technology

[0008] 1. When the forged ring is manufactured, the heating temperature of the raw material is high and the surface is oxidized, and the oxide is pressed into the surface of the chain ring during die forging, which will easily cause forging defects on the surface of the chain ring and affect the mechanical properties;

[0009] 2. The heating temperature of the blank before forging is inconsistent, and it is difficult to control the initial forging and final forging temperature, resulting in inconsistent pitch size of the chain links, which affects the comprehensive mechanical properties of the chain;

[0010] 3. The energy consumption of the forged ring is more than three times that of the pressed ring;

[0012] 5. The raw materials for forging rings are 1.5 times that of pressed rings, and the working hours are 4 times that of pressed rings, and the manufacturing cost is high
