Abstract

The invention relates to welding devices, in particular to a spiral welding device of a conic electric pole reinforcement cage seam welder. The spiral welding device comprises a longitudinal reinforcement fixing device, a welding device body and a circumferential reinforcement fixing device. The circumferential reinforcement fixing device and the welding device body rotate around the longitudinal reinforcement fixing device. Circumferential reinforcements are welded to longitudinal reinforcements in a wound mode through the welding device body. The welding device body comprises a welding electrode and a pressure mechanism. The pressure mechanism exerts constant pressure to the welding electrode, so that constant pressure of a welding point is kept by the welding electrode. According to the spiral welding device of the conic electric pole reinforcement cage seam welder, the longitudinal reinforcements do not rotate, the circumferential reinforcements are welded in the wound mode, it is guaranteed that the longitudinal reinforcements are not twisted, high noise generated by rotation of the longitudinal reinforcements is avoided as well, the welding speed can be increased by over two times, it can be guaranteed that pressure of the welding electrode is constant all the time along with change of the diameter of a reinforcement cage in the welding process, and therefore welding quality is guaranteed.

Description

technical field

[0001] The invention relates to a welding device, in particular to a rotary welding device for a tapered electric pole reinforcement cage roll welding machine. Background technique

[0002] The tapered electric pole reinforcement cage is surrounded by multiple longitudinal steel bars to form a cone, and then the circular steel bars are welded to the longitudinal steel bars in a spiral manner. At present, the production of the tapered electric pole reinforcement cages is almost all done by hand. The production efficiency is low and the production cost is low. High, quality is difficult to guarantee, and some seam welding machines are used to produce steel cages, but the existing seam welding machines are difficult to be popularized on a large scale due to the shortcomings of low production efficiency, complicated operation, small adaptable range, and high noise.
