Manufacturing technology of novel moving blades of crusher

Abstract

The invention discloses a manufacturing technology of novel moving blades of a crusher. According to the technical scheme, the manufacturing technology is characterized by comprising steps as follows: cutting a profile into a plurality of moving blades along patterns, placing the moving blades on a machine tool for laser quenching, transferring the moving blades to a grinding machine for finish grinding, cooling the moving blades and the like. Surfaces of the moving blades can be heated and self-cooled at the high speed with the laser surface quenching technology, temperatures of the surfaces of the moving blades and heat penetration depths can be effectively controlled through control on the laser scanning speed and the laser power, and the heat affected zone is small and quenching stress and deformation are very small due to the high laser heating speed. The laser quenchingtechnology is short in period, the production efficiency is high, the technological process can be controlled by a computer easily, the automation degree is high, and the technology can be applied to a production line.

Description

【Technical Field】 [0001] The invention belongs to the field of mechanical processing, and relates to a manufacturing process of a new type of crushing motorized knife, in particular to a laser surface quenching process of a new type of crushing motorized knife. 【Background technique】 [0002] Since the advent of lasers in the 1960s, laser technology, as a high-tech that has attracted worldwide attention, has been widely used in various industries. In recent years, laser surface treatment technology has not only developed rapidly in research and development, but also has made considerable progress in industrial applications, becoming a very active emerging field of surface engineering. Laser surface treatment can not only change the microstructure of the substrate surface material through laser quenching and surface fusion, but also change the chemical composition and microstructure of the substrate surface at the same time through laser cladding, vapor deposition and alloying.

AI Technical Summary

Problems solved by technology

[0003] Laser quenching technology has not been really applied to the moving knife of the crusher at present. The existing method of heat treatment for the moving knife of the crusher is usually to carry out overall or partial large-area heating on the moving knife or adopt high-frequency quenching treatment. The heating time is long and the dynamic The knife is prone to deformation, and some manufacturers also use focused laser spot to irradiate the surface or cutting edge of the moving knife, which can easily cause melting and cause the moving knife to not work normally.
