Background
At present, the steel bar pole skeleton in the pole industry is formed by roll welding, and a product company is also provided with four roll welding machines, but the problems of high labor intensity, low production efficiency and high labor cost still exist.

⑴ In the welding process of the electric pole framework, the straightened steel bars and the straight steel bars are required to be integrally and reversely transported to a welding platform, and operators drag and sort the steel bars forcefully one by one, so that the steel bars are distributed and penetrated in sequence. Because the reinforcing steel bars in each bundle are all mutually crossed and arranged in disorder, and each electric pole needs 3-4 reinforcing steel bars with different lengths, the platform reinforcing steel bars are placed in disorder, time and labor are consumed during sorting, and potential safety hazards exist.
⑵ Because the warping of the end part of the straight bar steel bar after hot cutting affects the bar threading, the bar threading is needed after the head of each bar is cut by a hydraulic clamp. 13.5 tons of steel bars are consumed per class, two operators need to sort more than 6 tons of steel bars per person, each person penetrates the steel bars 405 times (the class yield is calculated according to 45 pieces), the labor intensity is high, a large amount of time is occupied, and the production efficiency is severely restricted.
2. The labor amount is large, and the labor cost is high.
In order to reduce the production cost, 14.98 meters of steel bars for welding a 15-meter electric pole framework are cut off and blanking after 14 coils of steel bars are straightened by cold drawing, so that 1 person needs to be arranged for straightening the steel bars. Therefore, 4 operators (1 straightener, 2 cloth bars, penetrating bars and 1 welder) are required for taking the 15-meter electric pole framework singly, and the labor cost is high.
