Problems solved by technology

The current feeding rollers are made of heat-resistant steel with a smooth surface. Whether manual feeding or automatic feeding is used, the feeding speed will be affected during the feeding process.
And as the use time increases, the surface smoothness will become larger and larger, making the heat treatment efficiency lower

Abstract

The invention provides a heat treatment feeding roller bar. The heat treatment feeding roller bar comprises a cylindrical roller face and a friction increasing coating sprayed on the roller face, the cylindrical roller face is square hatching knurling and comprises double-walking-direction grooves and square protruding blocks, 45-degree included angles are formed between the walking directions of the grooves and the axial direction of the roller bar, included angles formed between the grooves in different directions are 90 degrees, one diagonal line of each square protruding block is parallel to the axial direction of the roller bar, the other diagonal line of each square protruding block is perpendicular to the axial direction of the roller bar, paint used in the friction increasing coating are WC-TiC-Co cemented carbide powder, and the spraying method is heat spraying. According to the heat treatment feeding roller bar, the shortcoming that in the prior art, the feeding speed is low due to slipping caused by small friction force is overcome by increasing the surface friction force of the roller bar, and the feeding efficiency is improved.

Description

technical field [0001] The invention relates to a rod, in particular to a feed rod used in a heat treatment feed device. Background technique [0002] The feed roller is a common component in the roller table assembly line. The use of the roller can make the blank flow process smoother and ensure the smooth progress of the heat treatment process. The current feeding rollers are all made of heat-resistant steel with a smooth surface. Whether manual feeding or automatic feeding is used, the feeding speed will be affected during the feeding process. And as the length of use increases, the surface smoothness will become greater and greater, making the heat treatment efficiency lower. [0003] At present, thermal spraying technology has been widely used. Thermal spraying processes include flame spraying, oxygen-ethylene flame spraying welding, high-velocity flame spraying, arc spraying, plasma spraying, atmospheric plasma spraying, low-pressure plasma spraying, etc. The base ma...
