Forming device and method for seam heat treatment of high-frequency straight seam welded steel pipe

Abstract

A forming device and method for seam heat treatment of high-frequency straight seam welded steel pipes, belonging to the technical field of high-frequency straight seam welded steel pipe processing, in order to solve the problem that when the forming device transports steel pipes, multiple driving structures are usually required to drive at the same time, which is easy In the case of excess power, and the problem of increasing the cost of use, the invention includes a base shell, a base shell, and a feeding and conveying assembly fixedly installed at both ends of the top surface of the base shell and a feeding and unloading conveyor assembly respectively, and the middle part of the top surface of the base shell The welding scraping assembly and the water-cooling cooling assembly are respectively installed, a water storage tank is fixedly installed at one end of the inner cavity of the base shell, and a motor is fixedly installed on the bottom surface of the other end of the inner cavity of the base shell. The present invention realizes that one motor can simultaneously complete multiple The driving effect is convenient to use, and the problem of excess power of the motor is avoided, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of high-frequency straight seam welded steel pipe processing, in particular to a forming device and method for heat treatment of a high frequency straight seam welded steel pipe weld seam. Background technique [0002] High frequency straight seam welded steel pipes can be divided into straight seam high frequency resistance welded steel pipes and straight seam high frequency induction welded steel pipes according to different high frequency welding processes. The forming process generally adopts roll bending cold forming. High-frequency straight seam welded steel pipes are generally produced in small diameters, generally below 660mm or 26 inches in outer diameter. Its characteristics are: fast welding speed, for example, for steel pipes with an outer diameter of less than 1 inch, the maximum welding speed can reach 200 m / min. [0003] In the document CN201610160088.2, a combined device for extrusion formi...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a forming device and method for seam heat treatment of high-frequency straight seam welded steel pipes. This device is used to work, thereby solving the above-mentioned background. In actual use, steel pipes need transmission mechanisms such as motors to move them The ones that are conveyed before are first extruded by the forming device, and then welded to the gap of the steel pipe by the welding head. Usually, water cooling is required for cooling treatment. However, when water cooling is performed, an external water pump is usually required to pump the water out. And it requires manpower to continuously add water, which not only increases the cost of use, but also consumes manpower, and only using the forming device to transport the steel pipe forward will easily cause excess power of the motor, resulting in waste of resources and inconvenient use.
