Synchronous copying winding device for plastic forming for socket of spigot-and-socket pipe

Abstract

The invention relates to the technical field of forming for plastic layers of pipelines, and provides a synchronous copying winding device for plastic forming for a socket of a spigot-and-socket pipe.The synchronous copying winding device for plastic forming for the socket of the spigot-and-socket pipe comprises a movable press-fit mechanism and a fixed-point press-fit mechanism, wherein the movable press-fit mechanism comprises a guide rail arranged in a manner of being parallel to the central shaft of a pipe body; a movable frame capable of moving along the guide rail is arranged on the guide rail; the movable frame is provided with a liftable press roll frame; a rotatable movable press roll is arranged on the press roll frame; the movable press roll is provided with a copying press surface fitted with the outer contour of the socket of the pipe body; the fixed-point press-fit mechanism comprises a fixed frame, and a liftable press roll frame is arranged on the fixed frame; and a pipe body press roll is arranged on the press roll frame. By this, according to the synchronous copying winding device for plastic forming for the socket of the spigot-and-socket pipe, through the fixed-point press-fit mechanism and the movable press-fit mechanism, a protective layer is formed at an equal-diameter part and a socket part of the outer wall of the pipe body separately.

Description

technical field [0001] The invention belongs to the technical field of pipe plastic layer forming, and in particular relates to a profiling synchronous winding device for plastic forming of a socket of a socket. Background technique [0002] Forming a plastic layer such as polyethylene or polyurethane on the outside of the pipe is considered the best way to prevent corrosion. [0003] For ordinary pipes (equal-diameter pipes) with regular shapes, winding protection is easy to achieve. However, for unequal-diameter pipes such as socket pipes (such as the structure disclosed in CN201820747877.0 patent), due to the presence of equal-diameter parts and unequal-diameter parts (such as the socket part of socket pipes), the existing equipment The pressure roller can only press the regular position of the tube body. The lamination of the plastic layer cannot be realized for the socket part with complex convex-concave structure. [0004] Therefore, the existing equipment cannot re...

AI Technical Summary

Problems solved by technology

However, for unequal-diameter pipes such as socket pipes (such as the structure disclosed in CN201820747877.0 patent), due to the presence of equal-diameter parts and unequal-diameter parts (such as the socket part of socket pipes), the existing equipment The pressing roller can only press the regular position of the tube body

For socket parts with complex convex and concave structures, it is impossible to press the plastic layer

[0004] Therefore, the existing equipment cannot realize the winding protection of unequal-diameter pipes, and can only be sprayed for protection, which has a low protection level and poor effect

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
