Welding device and welding method for socket and spigot joint of winding pipe

Abstract

The invention discloses a welding device and welding method for a socket and spigot joint of a winding pipe. The device comprises a movable base and a welding device body arranged on the movable base;the welding device body comprises a heating plate device, a welding device main frame, a pipe material clamping device and a pipe fitting installing device; the heating plate device is arranged on the middle portion of the welding device main frame; the pipe material clamping device and the pipe fitting installing device are installed on the two sides of the heating plate device correspondingly;the movable base comprises sliding wheels arranged at the bottom of the welding device main frame and main frame moving guide rails in sliding connection with the sliding wheels; the main frame movingguide rails are arranged on the two side edges of the base in parallel; and the welding device body can move as a whole. According to the welding method, application is convenient, the product performance is reliable, and the welding connection quality between the winding pipe and an injection molding socket and spigot joint pipe fitting is guaranteed. The problems that during operation of a traditional welding device, frequent disassembling is needed, the center alignment difficulty is large, human power consumption for heating plate taking and assembling is large, and a large-caliber pipe material cannot be moved easily are solved.

Description

technical field [0001] The invention belongs to the technical field of winding pipe processing, and in particular relates to a welding device and a welding method for a winding pipe socket joint. Background technique [0002] The polyethylene structural wall winding pipe has the advantages of corrosion resistance, low frictional resistance, wear resistance, etc., has high ring stiffness, deep buried, and good overall molding process, high seam tensile strength and corrosion resistance, and longer life; With a variety of reliable and convenient connection. This kind of pipe has become a hot spot for investment in plastic drainage and sewage pipes. At present, there are A-type pipes, B-type pipes, and inner rib-reinforced spiral corrugated pipes for polyethylene structural wall winding pipes. In the connection of this type of composite pipe, the joint pipe fitting and its connection structure with the pipe are very important. [0003] Due to the forming process of the wound...
