Online heating distortion correcting device, system and method for profile

Abstract

The invention discloses an online heating distortion correcting device for a profile, comprising a straightening cylinder; the straightening cylinder is connected with a tension control system, a main hydraulic pump station and a cooling system; one side of the strengthening cylinder is provided with a stretching head device, and one side of the stretching head device is provided with a twisting head device; the twisting head device is connected with an auxiliary hydraulic pump station; the stretching head device and the twisting head device are provided with same temperature measuring systems; a negative water cooled cable of the stretching head device is connected with a heating power supply, and a positive water cooled cable of the twisting head device is connected with the heating power supply through a conducting busbar; two ends of the profile are directly and electrically heated, distortion correction begins after two ends of the profile are heated to the set temperature, and the profile is rapidly and efficiently heated through the closed loop control of an infrared temperature measurement and temperature control system to the power supply; due to the control for the tension of a hydraulic system, the constant output of a stretching force is ensured, and stretching by using a constant stretching force is realized; and the twisting angle is precisely controlled, the problem that the online heating insulation distortion correction of the profile is difficult in the distortion process is solved, the degree of automation is high, the distortion correcting quality is improved, and the distortion correcting efficiency is increased.

Description

Technical field [0001] The invention belongs to the technical field of metal profile straightening methods, and in particular relates to an on-line heating torsion straightening device, system and method for metal profiles. Background technique [0002] At present, for the processing of profiles, after the cold drawing operation, many profiles have serious distortion problems, and the traditional method is to manually twist and straighten the profiles by the operator. This method is difficult to work, labor intensive, and low production efficiency. Summary of the invention [0003] In order to overcome the above shortcomings of the prior art, the purpose of the present invention is to provide an on-line heating torsion correction device, system and method for profiles, which solves the technical problems of high labor intensity and low production efficiency in traditional manual work. Features of high qualification rate and high control accuracy. [0004] In order to achieve the a...
