Method for preventing metal materials from being scratched on tube wall in tubular annealing furnace

Abstract

The invention discloses a method for preventing metal materials from being scratched on a tube wall in a tubular annealing furnace. The method comprises the following steps that S1, a roll of strip-shaped metal material is taken, namely a metal strip body; a motor I, a rotating column, a first rotating cylinder, a first connecting column, a second connecting column, a third connecting column, a first fixing column, a polishing and rotating column I and a polishing and rotating column II are used in cooperation, burrs on the metal strip body are reduced, and the situation that the metal strip body jumps up and down is avoided; a second connecting plate can move up and down by rotating a second rotating disc, the metal strip body is adjusted to be bent upwards, bending deformation of materials in a furnace tube can be effectively reduced, the probability that the surfaces of the materials are scratched is reduced, and the second connecting plate can move left and right by rotating a third rotating disc. The position of the metal strip body entering the furnace tube is adjusted according to the scratched position, and the problem that the metal strip body is scratched due to the limitation of the inner diameter of the furnace tube is solved.

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a method for preventing metal materials from being scratched on tube walls in a tube annealing furnace. Background technique [0002] At present, the metal processing market (CNC processing, etc.) has an increasing demand for metal profiles in order to improve processing efficiency, save costs, and reduce losses. ) requirements are getting higher and higher, which puts forward higher requirements for the control of metal materials in the process of processing. Annealing is an indispensable link. The quality of annealing is related to the surface quality, hardness stability and profile of stainless steel profiles The size of the residual stress. [0003] Normal tubular annealing generally consists of a feeding part, a cleaning part, an annealing furnace heating part, an annealing furnace cooling part, and a material receiving part. The furnace tubes in the annealing furna...

Problems solved by technology

[0005] The metal bar body is a long material, which is annealed as a whole, and can be rotated independently through the set rotating tube, driving the second connecting tube to slide in the front and rear directions inside the chute three, and can be bent according to the actual situation of the metal bar body. Targeted alignment of the area, the alignment here refers to the alignment process in the horizontal direction, and it is convenient to replace and maintain a single rotating tube, through the first driving motor, the third rotating rod, the The two rotating rods and the second tension wheel are used in conjunction to make the metal strip body move towards the direction close to the metal strip guide box, and the normal operation of the tension mechanism as a whole can be realized through a first driving motor, avoiding the occurrence of multiple motor installations It is not convenient to maintain the same force on the outer surface of the metal strip body;
