Abstract

The invention belongs to the field of mechanical blade design, and relates to a 7CrSiMnMoV steel netting blade and a manufacturing method thereof, the adopted die steel raw material is 7CrSiMnMoV steel, the 7CrSiMnMoV steel netting blade has the advantages of being good in obdurability, greatly prolonging the service life of the netting blade and being small in steel quenching deformation, the requirement of the netting blade for surface precision is met, and due to the fact that the netting blade belongs to a consumption piece, the purchase demand is large, the processing cost is high, and the production and purchase cost of enterprises is effectively saved.

Description

Technical field [0001] The present invention belongs to the field of mechanical blade design, involving a 7crSimnmov steel pulling blade and a manufacturing method thereof. Background technique [0002] The pull-on blade is installed on a metal pull-up machine. It is a necessary cutting tool for the production of metal distribution products. The blade specification variety, and the heat treatment is difficult. As the demand for the spreading product is increased year by year, the amount of the blade also increases year by year. The scaled blade processing object is mainly a metal plate, and the thin edge is elongate. Due to the particularity of processing, the blade requires both high hardness, strong toughness, wear resistance, and a certain thermal hardness, but also high anti-fatigue breakability, especially for the use of performance requirements. The market is existing with a brushed blade product. The material is mostly H13 steel. The disadvantage is to form a mesh carbide,...
