Heat treatment equipment for welding seam of numerical control steel weldment

Abstract

The invention discloses heat treatment equipment for a welding seam of a numerical control steel weldment. The heat treatment equipment comprises a walking track, a controller glidingly arranged on the walking track and an adjusting beam connected onto the controller, wherein a heater and a temperature sensor which are aligned to the welding seam are arranged on the adjusting beam; and the heater and the temperature sensor are both connected with the controller. According to the heat treatment equipment, the temperature sensor is used for acquiring the instant temperature of a heating region and sending a temperature signal to a programmable logic controller, and the programmable logic controller is used for controlling a step motor to accurately control the walking speed of the controller so as to control heat input of the heater, enable the microcosmic crystalline phase structure of weld metal to realize an ideal phase change structure in an ideal temperature environment, guarantee the comprehensive mechanical performance of the weld metal, and effectively guarantee the safety performance of structure members.

Description

technical field [0001] The invention relates to the field of weld seam heat treatment of steel structure weldments, in particular to a numerically controlled weldment seam heat treatment equipment for steel structure weldments. Background technique [0002] Welding manufacturing is the basic method of steel structure connection. At present, the domestic structural parts manufacturing process generally uses manual hand-held flame heaters to preheat the weld seam or uses electric heating plates to preheat the post-treatment methods. The advantage of this method is that it does not Restricted by the component type, it has certain flexibility and scope of application, but it has high requirements for the operator, who needs to have high professional theoretical knowledge and rich practical experience, and has the disadvantages of high labor intensity and low efficiency. . For overcoming the deficiency of above-mentioned technical process, thus draw task of the present invention...
