Round tube welding device

Abstract

The invention discloses a round tube welding device and belongs to the field of machining equipment. The round tube welding device comprises a main support, a round tube containing mechanism and a welding mechanism. The round tube containing mechanism is horizontally arranged on one side above the main support. The welding mechanism is vertically arranged on one side of the round tube containing mechanism. The round tube containing mechanism comprises a containing support, a rotary motor, round tube fixing boards, a horizontally-moving hydraulic cylinder and tube bearing mechanisms. The rotary motor is horizontally arranged on one side of the containing support. The horizontally-moving hydraulic cylinder is horizontally arranged on the other side of the containing support. The two round tube fixing boards are vertically and symmetrically arranged. Multiple round tube clamping mechanisms are symmetrically arranged on the round tube fixing boards in the radial direction. The tube bearing mechanisms are vertically and symmetrically arranged at the portion, between the two round tube fixing boards, of the main support. The welding mechanism comprises a welding support, a horizontally-moving rod, horizontally-moving sleeves, lifting sleeves and round tube welding guns. The round tube welding device is simple in structure, round tubes can be rapidly and efficiently welded, round tube welding efficiency and quality are improved, and the production requirement is met.

[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, round pipes are widely used in our production and life. Round pipes can be used in pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry and special purposes. During the use of round pipes, round pipes need to be The two ends of the pipe are welded with flanges respectively, so that multiple round pipes can be connected by flanges, which can meet the needs of use. In the welding process of traditional round pipes, the joint between the flange and the round pipe is usually manually made. Welding, and then weld the gap between the flange and the round pipe. During the welding process, the round pipe needs to be rotated according to the welding progress. The work efficiency of the workers is low, the work intensity is high, and it is difficult to meet the requirements of large quantities. For round pipe welding, the existing round pipe welding device has a complex structure and troublesome operation. During the welding process of the round pipe, it is difficult for the round pipe placement mechanism to firmly fix the round pipes of various sizes and specifications, and it is difficult to ensure that the round pipe can be welded according to the welding process. It needs to rotate at a constant speed, and the existing welding mechanism is difficult to adjust conveniently according to the size specification of the round pipe and the welding needs. During the welding process, the welding mechanism can only weld the two sides of the round pipe in turn, which is difficult Welding both sides of the round pipe synchronously, the welding efficiency is low and cannot meet the needs of production and use
