Embodiment Construction

[0014] One side of the blade part of the blade steel plate of the double composite blade manufactured by the present invention is blade steel, and the other side is blade steel. Blade steel is a steel with high strength, high hardness, good toughness, and good anti-rust performance. Steel with good rust performance and excellent comprehensive mechanical properties, especially steel with hardness HRC≥55 after quenching, such as high-quality carbon structural steel with a carbon content greater than 0.6%, carbon tool steel, alloy tool steel, spring steel, bearings Steel, etc., are also useful for unique, secretive special blade steel. Blade steel can be selected ordinary carbon steel for use, and for anti-rust and attractive in appearance, blade steel also can be selected stainless steel for use. The cutting tool steel plate of the double compound blade for the cutting tool can be various combinations of the above-mentioned blade steel plates and blade steel plates.

Abstract

The process of making double composite steel plate for cutting tool includes the following steps: taking one large cutter body steel plate and one small cutter edge steel plate in the same length, shaving one slot in the cutter body steel plate and embedding the cutter edge steel plate in the slot, heating to the eutectic temperature and forging and welding in a forging machine in the thickness deformation of 48-52 %, heating to 1100-1200 deg.c and rolling in a rolling mill for welding in the deformation rate of 70-90 %, heat treatment, rolling and fixing, and splitting along the central line to obtain two double composite steel plates for cutting tool. The present invention has high compounding strength, stable product quality, low product cost, and may be used in producing shears and planer tool.

Description

technical field [0001] The invention relates to a composite cutting tool steel plate for making a cutting tool, in particular to a method for manufacturing a cutting tool steel plate with double composite blades for making a cutting tool. Background technique [0002] A cutting tool is a tool used to cut or chop something. The blade has a knife body, the knife body has a connected blade body and a blade, and the knife body can be connected with a knife handle. The blade is used to realize the cutting or chopping function of the cutting tool, and the blade body is used to fix the blade and determine the shape of the blade body. According to the function of the blade and the blade, the steel of the blade should have higher strength, higher hardness, better toughness, and excellent anti-rust performance, so that the blade of the blade is sharp, non-collapsing, and rust-free. Part of the steel can be made of ordinary carbon steel. In order to prevent rust and look beautiful, t...
