Automatic continuous annealing equipment for steel pipes

Abstract

The invention relates to automatic continuous annealing equipment for steel pipes. The equipment includes a machine seat and a workbench arranged on the machine seat. A heating device, a sample conveying device and an electric control device are disposed on the workbench. The electric control device is used for controlling operation of the heating device and the sample conveying device. The sample conveying device comprises a feeding disc, a receiving disc and a heating frame arranged therebetween. The heating frame is arranged right ahead the heating device, and is a cylindrical structure with round grooves arranged on the edge. The main shaft of the heating frame is in connection with a belt wheel through a synchronous belt, and the belt wheel is driven to rotate by a motor. In the invention, the heating frame matching the steel pipes in terms of pipe diameter and shape is arranged, and is connected to the belt wheel through the synchronous belt, so that the heating frame can rotate under driving of the servo motor, thus realizing automatic feeding and discharging, as well as automatic propelling and pullback of the steel pipes. Therefore, the processing time of each steel pipe is ensured, and the qualified rate of products is guaranteed.

Description

technical field [0001] The invention relates to an annealing device, in particular to an automatic continuous annealing device for steel pipes. Background technique [0002] Annealing is a heat treatment process for metals, which refers to slowly heating the metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. The purpose of annealing is to reduce hardness and improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust organization, and eliminate organizational defects. During the processing of the steel pipe, one end of the steel pipe needs to be annealed to reduce the hardness and meet the needs of subsequent processing. At present, since the existing automatic annealing equipment is not designed and manufactured for the annealing process of the steel pipe, it cannot meet the needs of the annealing process of the steel pipe. Therefore, at present, t...

AI Technical Summary

Problems solved by technology

At present, because the existing automatic annealing equipment is not designed and manufactured for the steel pipe annealing process, it cannot meet the needs of the steel pipe annealing process

Therefore, at present, in the annealing treatment of steel pipes, manual operations are often relied on. On the one hand, the degree of automation is low, the production efficiency is low, and the labor intensity of workers is high; relationship, it is difficult to guarantee the pass rate of the product
