Abstract
The invention relates to a scraper blade of a scraper conveyer for a coal mine and a manufacturing process, in particular to a nonmetal scraper blade of the scraper conveyer for the coal mine and the manufacturing process. At present, the scraper blade of the scraper conveyer for the coal mine is of an integral structure made of low alloy steel. The manufacturing process sequentially comprises the following steps of die forging forming, machining and heat treating, wherein the used material is generally 40Mn2 or 27SiMn. The nonmetal scraper blade of the scraper conveyer for the coal mine is formed by nonmetal materials and a metal insert bush. According to the nonmetal scraper blade of the scraper conveyer for the coal mine and the manufacturing process, a metal scraper blade is improved to be the nonmetal scraper blade, the production process is changed to be casting instead of original forging, the process is simplified, the weight and the production cycle of parts are greatly reduced, and the installing load of the scraper conveyer for the coal mine is greatly reduced.
Description
Technical field
The present invention relates to non-metallic material alternative metals field of material technology, specifically a kind of scraper conveyor for coal mines non-metal scraper plate and manufacturing process.
Background technology
At present, scraper conveyor for coal mines scraper plate is the integral structure of low-alloy steel, and its manufacturing process is: die-forging forming → machinework → heat treatment, uses material to be generally 40Mn2 or 27SiMn.Scraper conveyor for coal mines non-metal scraper plate of the present invention is by non-metallic material and metal is bushing forms.In the present invention, cockscomb is improved to nonmetallic, and production technology adds machinework by original forging has changed casting into and form, work simplification and significantly reduce pts wt and production cycle, and greatly reduce the installation load of scraper conveyor for coal mines.
Summary of the invention
The object of this invention is to provide a kind of scraper conveyor for coal mines non-metal scraper plate and manufacturing process, replace traditional scraper conveyor for coal mines low-alloy steel scraper plate and manufacturing process.Simplify production technology and significantly reduce part substance and production cycle, and greatly reducing the installation load of scraper conveyor for coal mines.
The technical solution adopted in the present invention is: the non-metallic material adopted in the present invention is 81% is urethane raw, its composition is: 30-50%TDI-toluene diisocyanate, 50-70%PTMEG-carbowax (tetramethylene), 18% is medical material, its composition is: 6-methyl-2,4 two degree of (methyl mercapto) phenylenes-1,3 diamines, 1% lubricating additive, its composition is: molybdenum disulphide refers to the mineral compound that chemical formula is MOS2.
The manufacturing process of its non-metal scraper plate is as follows:
1, non-metallic material is allocated according to aforementioned proportion;
2, be preset in aluminum alloy scraper plate mould by bushing for metal;
3, by clamping for the upper and lower mould of aluminum alloy scraper plate mould;
4, non-metallic material is heated to molten condition, heating-up temperature is at 350 ~ 300 DEG C;
5, casting non-metal scraper plate, pouring temperature is at 250 ~ 300 DEG C;
6, the demoulding after cooling, hardening time is that the manufacture of 2 hours non-metal scraper plates completes.
The invention has the beneficial effects as follows: 1. simplify production technology, shorten the manufacturing cycle.2. substitute low-alloy steel with non-metal, significantly reduce scraper plate weight.3. the significantly reduction of scraper plate substance, makes the installation load of scraper conveyor for coal mines obtain and declines to a great extent.
