Rotating electrode of seam welder for welding concrete pile reinforcement cages with different cross sections

Abstract

The invention relates to a rotating electrode of a seam welder for welding concrete pile reinforcement cages with different cross sections, which comprises a fixed electrode arranged on a conductive central shaft and a rotating disc arranged at the outer side of the fixed electrode, wherein the rotating disc is provided with an adjusting sliding seat; the adjusting sliding seat is provided with an adjusting sliding plate; the adjusting sliding seat is provided with an adjusting screw rod for adjusting the position of the sliding plate; the adjusting sliding plate is provided with a positioning shaft; a welding arm is connected with the adjusting sliding plate through the positioning shaft; the outer side of the welding arm is connected with a support bar through a positioning pin; and the end part of the outer side of the welding arm is provided with a balance. The rotating electrode of a seam welder for welding concrete pile reinforcement cages with different cross sections can be used for manufacturing reinforcement cages with various odd-shaped cross sections; in work, reinforcement cages with corresponding cross sections can be manufactured by simply replacing the fixed electrode with fixed electrodes with corresponding cross sections and replacing corresponding traction discs and reinforcement guide discs; and the structure has the advantages of simple structure, low failure rate, firm welding and high universality.

Description

technical field [0001] The invention relates to a welding rotary electrode of a seam welding machine, in particular to a seam welding machine rotating electrode used for welding the steel bar skeleton of concrete piles with different cross-sections. Background technique [0002] With the extensive use and popularization of prestressed concrete pipe piles, people have a deeper and more comprehensive understanding of the performance of pipe piles. Although tubular piles have excellent comprehensive performance, certain shortcomings have also been exposed. Some fields have begun to try precast concrete piles with non-circular cross-sections. Such as square cross-section piles, rectangular cross-section piles, trapezoidal cross-section piles, etc., and the steel skeletons used in these cross-section piles are also square, rectangular or trapezoidal cross-sections. The steel skeletons of this cross-section are more difficult to manufacture. At present, in the existing technology...

AI Technical Summary

Problems solved by technology

At present, in the existing technology, only square-section skeletons can be made by seam welding machines, and there are problems such as low production efficiency, high failure rate, and poor welding effect. Other skeletons with special-shaped cross-sections can only be completed by hand, which seriously restricts The development and application of special-shaped concrete piles
