Method for manufacturing super-flat compact type chain vertical ring

Abstract

The present invention relates to a method for manufacturing a super-flat compact chain vertical ring that is used for a scrape-plate conveyor, which is characterized in that the method comprises the following steps: chain steel is made into a material rod, and then the material rod is arranged on the chain braiding tire of the working table of a press machine to be bent into a chain ring with a large V-shaped port, and then the large V-shaped port of the chain ring is arranged inside a closing tire of the working table of the press machine to be pressed into a small V-shaped port; the braided chain ring is undertaken the welding procedures, and after the fur is removed, the chain ring is arranged on the tire tool of the working table of the press machine; a core tire is inserted into the curved formed chain ring and is arranged on a specially-made tire tool that guarantees the arc the chain ring after being pressed; pressure is applied on the core tire to be pressed to the required degree of the process; a part of the pressed flat planes is milled on a miller so as to reach the required size. The method of the present invention guarantees the consistence of the utilization stress of the vertical ring and the flat ring, thereby favoring the improvement of the mechanical performance, and having remarkable energy conservation effect, and not only reducing the manufacturing cost, but also improving the production efficiency, and the mechanical performance and the utilization effect of the chain ring are better than the forged ring.

Description

technical field [0001] The invention relates to a manufacturing method of a super flat and compact chain vertical ring which is mostly used in scraper conveyors. Background technique [0002] As the main component of the scraper conveyor, the chain is also a vulnerable part, and the consumption is very large. Due to the wide distribution of thin coal seams, abundant reserves, and various geological conditions in my country, the thickness of coal seams is generally 0.5-2.3m, and a considerable part of them is below 1.2m. Constrained by space, it is necessary to design a scraper conveyor equipment with a structure that meets the coal mining process requirements for thinner coal seams below 1.2m, with high yield, high efficiency and high reliability. In order to adapt to changes in scraper conveyors, it is necessary to design super compact flat chains. Using large-sized super-compact flat chains instead of small-sized standard chains can increase the mechanical properties of t...

AI Technical Summary

Problems solved by technology

[0007] 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;

[0008] 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;

[0009] 3. The energy consumption of the forged ring is high;

[0010] 4. Forging rings use more raw materials, longer working hours and high manufacturing costs
