Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel pipes, and more specifically to post-processing equipment and a processing process for cold-rolled stainless steel pipes. Background Art

[0002] "Cold rolling" is a metal processing process. During the cold rolling process, the metal material is rolled under the pressure of the roller at room temperature to reduce its thickness, make the surface smoother and flatter, and improve the mechanical and physical properties of the material.

[0003] Cold-rolled stainless steel pipe is a stainless steel pipe made by cold rolling process. Cold rolling process is a process for processing metal materials at room temperature. It mainly uses cold extrusion or cold drawing to make the material obtain the desired shape and size during plastic deformation. For stainless steel pipes, cold rolling process can significantly improve the precision, surface finish and mechanical properties of the pipe. Stainless steel pipe itself has excellent corrosion resistance. After cold rolling treatment, a dense oxide film is formed on its surface, which further enhances the corrosion resistance. After cold rolling of stainless steel pipe, it is convenient for subsequent cutting, bending, welding and other processing operations on stainless steel pipe.

[0004] After cold rolling, stainless steel pipes need to be cut. When cutting stainless steel, the existing cutting machine will produce violent vibrations, which can easily cause the stainless steel pipe to resonate, resulting in poor cutting effect, and the cut surface is prone to deformation, unevenness or burrs. After cutting, the cut surface needs to be polished. In view of this, we propose a post-processing equipment and processing process for cold rolled stainless steel pipes. Summary of the invention

After the stainless steel pipe is clamped and tightened, the plug column is inserted into the corresponding plug hole on the circumferential outer wall of the fixed cover, so that the rotating plate is fixed to the circumferential outer wall of the fixed cover and stops moving, thereby ensuring that the stainless steel pipe can be clamped and fixed by the clamping assembly when being cut, reducing the resonance with the cutting disk, improving the cutting effect, and further solving the problem that resonance is easily generated when cutting the stainless steel pipe, resulting in poor cutting effect.

There are four clamping plates (304), two of which form a group and are symmetrically distributed on both side walls of the clamping sleeve (303). The side walls of the clamping plates (304) are arc-shaped curved surface structures.

10. The processing technology of the cold-rolled stainless steel pipe post-processing equipment according to claim 9, characterized in that: The following steps are involved: S1, unloading, inserting the stainless steel tube from the inner cavity of the round tube (407), passing through the inner cavity of the clamping sleeve (303) through the round hole (302), until being inserted into another set of corresponding clamping components (3); S2, clamping, by pushing the push plate (310), driving the rotating plate (309) to rotate along the circumferential outer wall of the clamping sleeve (303), causing the arc plate (307) to slide inside the arc groove (305), further driving the lever (308) to push the clamping plate (304) to clamp the stainless steel pipe. After the stainless steel pipe is clamped and tightened, the plug post (312) is inserted into the corresponding plug hole (315) on the circumferential outer wall of the fixed cover (301), so that the rotating plate (309) is fixed to the circumferential outer wall of the fixed cover (301), and stops moving; S3, cutting, the rotation of the motor 1 (102) drives the pulley 1 (103) to rotate, and further drives the pulley 2 (105) to rotate through the synchronous belt (104), and the pulley 2 (105) drives the rotating shaft (106) to rotate, so that the cutting disk (107) rotates at a high speed, and then the rotation of the motor 2 (401) drives the screw rod (402) to rotate, and the screw rod (402) drives the slider (406) to move forward, and further drives the stainless steel tube in the inner cavity of the round tube (407) to move forward until it is cut by the cutting disk (107); S4, grinding. When the stainless steel pipe is cut, the gear (409) is in contact with the rack (410) and meshed with each other. When the round pipe (407) moves forward, the gear (409) is driven to rotate and move forward along the top surface of the rack (410). The gear (409) drives the round pipe (407) and the clamping assembly (3) to rotate, further causing the cut stainless steel pipe to rotate. The stainless steel pipe moves from the side wall of the cutting disc (107) to the side wall of the grinding disc (108) for grinding. The high-speed rotating grinding disc (108) cooperates with the rotating stainless steel pipe to grind the cut surface of the stainless steel pipe to be smoother and flatter.
