A traction type seam welding machine

Abstract

The invention relates to a traction type rolling welding machine, which comprises a master disc, a welding table reducing mechanism, an expanding mechanism, a welding mechanism, a traction disc chuck and a traction trolley, wherein the traction disc chuck keeps synchronous rotation with the master disc under the transmission of transmission square steel while clamping longitudinal bars of a steel reinforcement cage to make axial motion under the driving of the traction trolley. The traction disc chuck keeps synchronous rotation with the master disc under the transmission of the transmission square steel while dragging the longitudinal bars of the steel reinforcement cage to make axial motion under the driving of the traction trolley, so the bar twisting of the steel reinforcement cage can be avoided.

Description

technical field

[0001] The invention relates to a concrete product production machine, in particular to a rolling welding machine for making reinforced concrete pipe reinforcement cages. Background technique

[0002] At present, automatic variable diameter roll welding machines are widely used in China to make steel cages. The automatic variable-diameter roll welding machine pushes out the steel bars in the bar-piercing pipe through the bar-pushing mechanism to form longitudinal bars. The rib-pushing disc and the main disc are connected by a connecting cylinder to achieve synchronous rotation. However, due to manufacturing errors, the rib-pushing disc and the main disc cannot actually rotate accurately and synchronously. Muscle phenomenon. Contents of the invention

[0003] The object of the present invention is to provide a traction type seam welding machine, which can be used to make a reinforcement cage, and the reinforcement cage will not have twisted tendons. [00...
