Problems solved by technology

However, during the sealing process of hot-melt butt welding, excess plastic melt will form on the inner and outer walls of the pipe and adhere to the inner and outer surfaces of the pipe due to external force extrusion, thereby affecting the outer diameter of the pipe and the appearance quality. During the installation process, it is impossible to carry out socket electrofusion welding with electrothermal fusion connection pipe fittings, such as direct, elbow, tee, etc., so the pipe must be repaired after the thermal fusion butt welding sealing treatment to ensure the interface size and Appearance Quality
[0003] The existing device for repairing and processing edges of steel-plastic composite water supply pipes uses a special fixture to fix the steel-plastic composite water supply pipes. The processing tool is fixedly installed on the spindle box of a similar cutting machine tool, and the axial displacement tool is moved through the axial movement of the carriage. Carry out rotary cutting to achieve the purpose of repairing the nozzle, that is, when repairing and processing the edge of the steel-plastic composite water supply pipe, the cutting tool is positioned on the center line of the composite pipe. Since the diameter of the steel-plastic composite water supply pipe varies from 50 mm to 800 mm, The larger the pipe diameter, the greater the non-concentricity, commonly known as the greater the ellipticity, which will cause damage when repairing the edge of the steel-plastic composite water supply pipe, and even require rework and repair; at the same time, the fixed machine tool type steel-plastic composite water supply pipe The device for repairing and processing the edge occupies a fixed space, and the processing efficiency is low

Embodiment 1

[0015] like figure 2 As shown, the existing equipment for repairing and processing the edge of the original large-diameter steel-plastic composite water supply pipe uses a special fixture to fix the steel-plastic composite water supply pipe, and the processing tool is fixedly installed on the spindle box of a similar cutting machine tool, that is: repair and process steel-plastic composite water supply pipes. The edge of the composite water supply pipe is positioned on the center line of the composite pipe. Since the diameter of the steel-plastic composite water supply pipe varies from 50 mm to 800 mm, the larger the pipe diameter, the greater the misalignment, commonly known as the greater the ellipticity, resulting in When the edge of the steel-plastic composite water supply pipe is repaired and processed, damage will occur, and even rework is required; at the same time, the fixed machine tool type device for repairing and processing the edge of the steel-plastic composite w...

Abstract

The invention provides a trimming device for an end face of a large-diameter steel-plastic composite water feeding pipe. The trimming device for the steel-plastic composite pipe comprises a rotary cutting tool, a surface positioning ball, an end face positioning baffle, a rotary cutting tool locking device, a high-speed motor, a handle and a trimming device assembly; the trimming device is positioned by the outer surface of the pipe so that the trimming quality is guaranteed; and meanwhile, a special field is not occupied and the edge of the steel-plastic composite pipe is movably trimmed, and the trimming device can be widely applied to the field of water supply and sewerage works.

Description

technical field [0001] The invention relates to the field of large-diameter steel-plastic composite water supply pipe processing equipment, which is mainly used in a device for repairing and processing edges after the end surface of the steel-plastic composite water supply pipe is sealed. Background technique [0002] After the steel-plastic composite water supply pipe is cut to length, the section of the pipe will expose the steel skeleton layer. In order to ensure that the exposed steel skeleton layer will not be corroded by the conveying medium during the water supply process and ensure the service life of the pipe, the cut section of the pipe must be sealed. Treatment, that is, the plastic sealing ring is welded to the cut section of the pipe by hot-melt butt welding, and the welded plastic sealing ring achieves the purpose of protecting the steel skeleton layer. However, during the sealing process of hot-melt butt welding, excess plastic melt will form on the inner and...
