Steel pipe circular weld mechanism

Abstract

The invention discloses a steel pipe circular weld mechanism and belongs to the field of steel pipe machining mechanical equipment. The steel pipe circular weld mechanism comprises a horizontal moving support, a rotation motor, a steel pipe holding plate, a lifting motor and a steel pipe welding gun, wherein a plurality of universal wheels with brakes are evenly arranged on the lower side of the horizontal moving support; the round steel pipe holding plate is horizontally and rotatably connected on the upper side of the horizontal moving support; a plurality of steel pipe clamping mechanisms are symmetrically arranged on the steel pipe holding plate in the radial direction; a lifting guide rod and a lifting screw rod are vertically arranged on one side of the upper portion of the horizontal moving support correspondingly; a lifting support can go up and down along the lifting guide rod; hold-down nuts are connected on an adjustment screw rod on the upper side and the lower side of a fixation plate in a threaded mode; a horizontal moving sleeve is horizontally arranged at the upper end of the adjustment screw rod; and the steel pipe welding gun can move horizontally along the horizontal moving sleeve. The steel pipe circular weld mechanism is reasonable in structural design and capable of vertically and firmly fixing steel pipes and conducting circular welding on the steel pipes conveniently and efficiently, and meets the requirements for machining and using.

[0002] Welding is a manufacturing process and technology for joining metal or other thermoplastic materials by means of heating, high temperature or high pressure. According to the specific welding process, welding can be subdivided into gas welding, resistance welding, arc welding, induction welding and laser welding, etc. Special welding, steel pipes are widely used in our production and life. Steel pipes can be used in pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry and special purposes. During the use of cylinder pipes, both ends of steel pipes need to be The flanges are welded separately, so that multiple steel pipes can be connected by flanges to meet the needs of use. In the welding process of traditional steel pipes, the flanges and steel pipes are generally spot welded manually, and then the French steel pipes are welded together. The gap between the flange and the steel pipe is welded. During the welding process, the steel pipe needs to be rotated according to the welding progress. The work efficiency of the workers is low and the work intensity is high. It is difficult to meet the welding of large quantities of steel pipes. The existing steel pipe welding The structure of the device is complicated and the operation is troublesome. During the welding process of steel pipes, it is difficult for the steel pipe placement mechanism to firmly fix steel pipes of various sizes and specifications, and it is difficult to ensure that the steel pipes can rotate at a uniform speed according to the welding requirements. The welding efficiency is low and cannot meet production needs
