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...

Examples

Embodiment 1

[0034] Such as Figure 1-5 As shown, the method for preventing metal material from scratching the tube wall in the tube annealing furnace comprises the following steps:

[0035] Step 1: Take a roll of strip-shaped metal material, which is the metal strip body 12;

[0036] Step 2: Pass the metal bar body 12 through the inside of the first ring encoder 13 into the annealing device, and control the first ring encoder 13 to slide on the upper surface of the first support base 1 through the bar-shaped groove 1, so that the metal bar body 12 Pass through the first limit stop post 14 to the position between the first tension wheel 66 and the second tension wheel 68, start the first drive motor 8, and drive the third rotating rod 70 to rotate, the outer surface of the third rotating rod 70 The socketed gear four is engaged with the gear three socketed on the outer surface of the second rotating rod 67 near the rear end, thereby driving the second rotating rod 67 to rotate, and then d...
