A rebar height adjustment device for submerged arc stud welding

Abstract

The invention discloses a rebar height adjustment device for submerged arc stud welding. The rebar height adjustment device comprises a submerged arc stud welding welding gun and a height adjustment box, wherein the submerged arc stud welding welding gun is provided with a height adjustment sliding block; a rebar clamping device is mounted at the front end of the welding gun and comprises a pressure spring, a pressure adjustment block, an insulating spacer, a chuck screw, the height adjustment sliding block and a rebar chuck; the pressure spring, the pressure adjustment block, and the insulating spacer are sequentially connected with the front end of the welding gun; a gland nut is mounted on the chuck screw in a spiral manner; the height adjustment sliding block can be adjusted in a length telescopic manner to drive up-down displacement of the rebar chuck so as to enable the clamped rebar to move up and down; the depth of the cavity of the height adjustment box is greater than the height of a submerged arc stud welding soldering flux box, and the difference value between the depth and the height is equal to the rebar stretching length required by the welding technology. With adoption of the rebar height adjustment device, the step of adjusting the rebar stretching length is simplified, the process of adjusting the rebar hoisting height is eliminated, and the submerged arc stud welding welding efficiency is remarkably improved.

Description

technical field [0001] The invention relates to the field of welding auxiliary tools, in particular to a steel bar height adjusting device for submerged arc stud welding. Background technique [0002] Submerged arc stud welding is a new type of welding method for T-shaped welding of embedded parts. It is a welding method that combines submerged arc welding and stud welding. It has both efficient and fast stud welding and submerged arc welding safety. With beautiful features, it is widely used in the welding of embedded parts in steel structure buildings. The automatic welding procedure of submerged arc stud welding is: press the switch—start the arc—lift up—ignite the main arc—welding time is up—insert the steel bar into the molten pool—turn off the arc, and end. The specific operation steps are: use the welding torch to clamp the steel bar, adjust the appropriate extension length and lifting height of the steel bar, put the support plate under the welding torch on the flux...

AI Technical Summary

Problems solved by technology

Due to the size error of the steel bar blanking, the length of each steel bar is inconsistent. Therefore, it is necessary to adjust the extension length and lifting height of the steel bar according to the above method before each welding. This method requires the cooperation of two people, one with the welding torch and the other with a ruler. To measure, it often requires multiple adjustments and measurements to meet the requirements, which is cumbersome and extremely inefficient
