Welding and forming device of concrete hollow square pile reinforcing cage

Abstract

The invention discloses a welding and forming device of a concrete hollow square pile reinforcing cage, which comprises an electrode profile modeling, an electrode welding arm, an electrode wheel assembly, a cam, a gear driving mechanism and the like, wherein the electrode welding arm is arranged on a main machine turnplate and can swing around a fixed point of the main machine turnplate; the electrode assembly is arranged on a rotating shaft of the electrode welding arm; the cam is arranged on the main machine turnplate; when a main machine rotates, the cam is driven by an inner gear driving mechanism to rotate; the cam is used as a profiling element of the motion track of an electrode wheel; the electrode profile modeling (an insulated material covered at a non-work part) is fixed on an engine seat of the main machine; the electrode profile modeling, the electrode wheel and the cam are in a non-radial mechanical connection; the motion track of the electrode wheel is limited between the cam and the electrode profile modeling; and the electrode wheel can accurately coincide with all points of the electrode profile modeling. The invention thoroughly solves the difficult problems of the welding and the forming of the square pile reinforcing cage distributed by any longitudinal ribs. The device has the remarkable characteristics of novelty, simpleness, reliability, stable welding quality and small loss of welding point strength.

Description

technical field [0001] The invention relates to resistance welding equipment, in particular to welding and forming equipment for concrete hollow square pile reinforcement cages, which can realize long-cage welding of any longitudinal reinforcement and circumferential reinforcement nodes on a square cross-sectional shape. Background technique [0002] Concrete hollow square piles and concrete circular square piles have different cross-sectional shapes and are suitable for different occasions, but the production process and process are basically the same. , traction mechanism, etc., when working, connect the upsetting longitudinal rib with the traction mechanism, the welding part of the longitudinal rib is closely attached to the electrode master, and the ring rib is introduced from the material plate through the welding arm, and the main machine and the material plate are in the same direction Rotate, while wrapping the ring bar around the welding part of the longitudinal bar...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to learn from the welding technology of the existing circular steel cage welding and forming equipment, overcome the defect that it cannot weld the square pile steel cage, and provide a kind of advanced technology for the welding and forming of the square pile steel cage, which is novel in concept, simple in structure, and capable of welding. Ensure that all corresponding points of the welding wheel and the electrode master form are kept equidistant during the welding process of the square pile reinforcement cage, so as to ensure stable welding pressure and reliable welding quality
