Abstract

The invention mainly solves a rod wire cold shear blade laser manufacturing structure and a manufacturing flow and a method. The gradient cladding is performed for a cobalt base alloy material under a shear blade shear surface stress point, and the cladding quantity of the cobalt base alloy is gradually reduced according to a shear force transfer descending path, so that the blade life is prolonged, and the cost consumption is reduced. In order to reduce deformation generated by laser cladding, the removing quantity of a working layer surface of the laser clad cobalt base material is reduced, so that the blade function is realized, and the manufacturing cost is reduced; and in the shear blade laser cladding process, a shear blade is fixed on a platform manufactured by gray cast iron for dispersing heat and stress generated in the machining process to effectively limit deformation and reduce subsequent machining difficulty.

Description

technical field [0001] The invention mainly solves the laser manufacturing structure, manufacturing process and method of bar wire cold shearing blades. Background technique [0002] Scissors are an essential part of metal shearing equipment for various steel production lines in iron and steel enterprises. They are generally made of steel containing precious alloy elements such as Cr, Mo, W, etc. The overall manufacturing cost is very expensive, and the consumption is large. The quality of the blade directly affects the quantity, quality and production efficiency of the products produced. The traditional bar wire shear blade is made of high-quality tool steel and alloy die steel through complex heat treatment and machining processes. Due to the high impact force, pressure and high temperature, the shear blade is required to have the characteristics of high strength, high hardness, high toughness, and high hardenability. Although the above-mentioned high-quality and high-co...
