AI Technical Summary

Technical Problem

Existing technologies suffer from low efficiency in filling and emptying quartz sand when connecting large quantities of irregularly shaped pipes, and precise filling of curved sections on long pipes is difficult to achieve, leading to increased pipe collapse.

Method used

A pipe bending device was designed, comprising a base plate, a large bending wheel, a bending handle, a quartz sand loading and unloading mechanism, and a quartz sand shaping and heating component. Through the cooperation of a telescopic sleeve rod and a fixing frame, the device enables precise filling and rapid pouring of quartz sand, and utilizes a thermally conductive silicone sleeve and a thermally conductive quartz sand layer to provide anti-collapse deformation support.

Benefits of technology

It enables precise filling and rapid emptying of quartz sand at the bends of irregularly shaped pipes, reducing pipe collapse and improving bending efficiency and effectiveness.

Abstract

This invention discloses a pipe bending device for irregularly shaped connecting pipes, comprising: a base plate, on which a large bending wheel is provided, the upper end of which is connected to a small bending wheel via a bending handle and clamps and restricts the pipe body to be bent; and a quartz sand loading and unloading mechanism, including a loading and unloading component and a quartz sand shaping and heating component. The loading and unloading component is configured with a telescopic sleeve rod, a fixing frame, a material support box, a material pushing magnetic plate, a movable rod, and a positioning and pushing plate to accurately move the thermally conductive silicone sleeve to the part to be bent and to facilitate subsequent rapid loading and unloading. The quartz sand shaping and heating component is configured with a heating wire, a graphene thermally conductive paper sleeve, a thermally conductive silicone sleeve, a temperature control switch, and a quartz sand thermally conductive layer to heat the part of the pipe body to be bent. The quartz sand thermally conductive layer inside the thermally conductive silicone sleeve provides anti-collapse deformation support for the pipe body to be bent, reducing the degree of pipe collapse at the bend of the irregularly shaped connecting pipe.
