A semi-automatic butt joint machine for manufacturing tee pipes

Abstract

The invention discloses a semi-automatic butt joint machine for manufacturing a three-way pipeline. The semi-automatic butt joint machine comprises a vertical plate seat, a horizontal plate seat, an interface fixing frame, pushing mechanisms, clamping mechanisms, binding lantern rings, a manual butt joint mechanism, a conveying mechanism, an inner repair welding device, a cutter and an outer repair welding device; one side of the vertical plate seat is provided with the horizontal plate seat arranged perpendicularly to the vertical plate seat, and two pipelines required to be connected throughbutt joint are respectively a vertical pipe and a horizontal pipe; the top side of the interface fixing frame is provided with the cutter, and one end of one pushing mechanism is provided with the inner repair welding device internally; one side of the binding lantern ring close to the vertical pipe is provided with the outer repair welding device; and all the bottom ends of the interface fixingframe, the pushing mechanisms and the clamping mechanisms are fixed to the top side of the vertical plate seat, and all the bottom ends of the binding lantern rings, the conveying mechanism and the manual butt joint mechanism are fixed to the top side of the horizontal plate seat. The semi-automatic butt joint machine is rational in structure, and facilitates guarantee of precision; repair weldingfor the interface joints of the pipelines can be performed, and the semi-automatic butt joint machine facilitates guarantee of the perpendicularity of three-way pipelines during butt joint; and the occurrence of deviation is reduced.

Description

technical field [0001] The invention belongs to the technical field of pipe-making machinery and equipment, in particular to a semi-automatic butt joint machine for manufacturing three-way pipes. Background technique [0002] Tee pipe fittings have a wide range of applications in the chemical and electric power industries. Generally, the manufacturing process of tee pipe fittings is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the tee, and to synchronously center it through the two horizontal side cylinders of the hydraulic press. The tube is extruded by movement, the volume of the tube becomes smaller after being squeezed, and the pressure of the liquid in the tube increases as the volume of the tube becomes smaller. Under the double action of the liquid pressure in the tube billet, it flows along the inner cavity of the mold and expands the branch pipe. However, in the actual operation process, due to the limitation of the...

Problems solved by technology

[0003] Temporary manufacturing of the required tee pipes during the operation basically cannot fully meet the necessary tee pipe manufacturing specifications, so when the tee pipe is temporarily installed on the job site, two mutually perpendicular supports are generally used to align the horizontal pipe and the tee pipe. The two pipes of the vertical pipe are positioned on the same plane, and then they are close to each other to achieve the purpose of connecting the horizontal pipe to the vertical pipe. Generally, the verticality of the two pipelines is observed by the naked eye of the workers. During the installation process, the pipeline needs to be adjusted manually. The process is cumbersome, and its technical standards are difficult to ensure the verticality of the two pipelines on the same horizontal plane, which affects the final installation. Existing During the docking process, the equipment generally uses machines to move the vertical pipes to complete the docking directly. The process is relatively hasty and it is not easy to ensure accuracy. If the docking process is fast, it is difficult to guarantee that there will be no deviation. It will lead to greater deviations in the installation of the flanges in the later stage, and then workers are required to rework, which is a waste of time; and in the prior art, after the pipes are butt-jointed, the joints are generally repaired manually, which wastes manpower and time, especially After the pipes are butted, there are still problems in the interior of the pipes that it is impossible to clean the part where the horizontal pipe extends into the vertical pipe and cannot repair the internal seam.
