Quick energy-saving gas soft nitriding method for automobile tire mould

Abstract

The invention relates to a quick energy-saving gas soft nitriding method for an automobile tire mould. The surface nanometer treatment is that: a common shotblast machine is provided with a set of pressurizing system, and a tire mould workpiece arranged in a charging tray of the shotblast machine with the pressurizing system is subjected to the surface nanometer treatment by a pressurizing shot blasting method; and the quick energy-saving gas soft nitriding method mainly comprises the placement of the workpiece, strong nitriding treatment, diffusion treatment and temperature reduction treatment; in a novel process of pre surface shot blasting nanometer and soft nitriding, because five hours of nitriding time is reduced to achieve the same soft nitriding effect, a great deal of energy consumption is reduced in each nitriding, and obvious economic benefit, social benefit and environmental protection benefit are generated; and the method has the advantages of shortening nitriding cycle and saving energy.

Description

technical field [0001] The invention relates to a fast and energy-saving gas nitrocarburizing method for an automobile tire mould. Background technique [0002] Energy conservation and emission reduction are the basic requirements for fully implementing the scientific outlook on development and promoting sound and rapid economic development. my country is currently facing the prominent contradictions of rapid economic and social development, population growth and resource and environmental constraints. At present, the ecological damage and environmental pollution in our country have reached the limit that the natural ecological environment can bear. In order to make the economic growth sustainable and alleviate the huge environmental pressure, it is necessary to promote economic growth in an environmentally friendly way. Energy conservation and emission reduction is to prevent pollution from the source, reduce resource consumption most effectively, and not discharge waste, ...

AI Technical Summary

Problems solved by technology

Slight wear and deterioration of surface morphology will cause mold failure. In addition, rubber and vulcanization residues are easy to accumulate in the patterns and grooves of the mold, which will affect the surface shape of the tire. Therefore, it must be disassembled and cleaned frequently, thus affecting Production efficiency of tire molds, increasing production costs

At present, steel tire molds mainly use gas nitriding for surface strengthening. This method has the disadvantages of long nitriding process cycle, high energy consumption, and high exhaust gas emissions.
