Numerical control automatic looping welding device

Abstract

The invention relates to a numerical control automatic looping welding device. The numerical control automatic looping welding device is characterized in that a wire is pressed into a ring shape through an arc pressing wheel assembly, the wire is pushed and cut off towards one side of a cut-off tool through a pushing block, an outer ring is clamped through a clamp after looping and cutting off, the ring-shaped wire is grabbed and translated to a V-shaped groove, and openings in the two ends of the ring-shaped wire enter and are aligned along the V-shaped groove; after alignment, the wire is pressed to a first electrode holder through a second electrode holder to form clamping, then the ring-shaped wire is loosened by the clamp, the two ends of the ring-shaped wire are tightly pressed by a lower electrode holder and an upper electrode holder through contraction of a lifting rod, and finally welding is conducted through electric heating, so that the staggered ring-shaped wire is successfully welded, and the welding effect is improved; a lower electrode tip and an upper electrode tip are fixed through screws and are convenient to disassemble and replace, and the effects of microcomputer programming, automatic straightening, automatic looping, automatic welding and automatic workpiece storage are finally achieved; and compared with the prior art, the numerical control automatic looping welding device has the advantages of being stable, reliable, high in automation degree and the like.

Description

technical field [0001] The invention relates to the field of material forming equipment, in particular to a numerically controlled automatic loop welding device. Background technique [0002] As a commonly used metal wire forming equipment, the ring forming machine is widely used in many fields such as hardware, home appliances, kitchen, and dust removal. Among the various circle making machines currently used in the market, the body basically includes a straightening mechanism, a transmission mechanism, and a forming mechanism. The body is equipped with a digital control system and is connected with the digital control system to control the circumference of the processing circle. The servo motor, the stepping motor used to control the diameter of the processing circle connected with the digital control system, the servo motor drives the transmission mechanism, and the stepping motor drives the forming mechanism, which can make the circumference and diameter of the processin...

AI Technical Summary

Problems solved by technology

[0003] However, the circle welding machine still has the following defects and deficiencies in the application process: after the metal wire is processed into a 360-degree circle, the two ends of the metal wire incision are easily staggered, and it is easy to fail to weld the two ends of the metal wire opening, which leads to the failure of the metal wire to form A full circle; after the metal wire is processed into a 360-degree circle, automatic welding cannot be realized
