AI Technical Summary

Technical Problem

During the hot expansion process of steel pipes, the clamping position is prone to slipping in the high temperature environment, causing the steel pipe to shake and affecting the hot expansion effect.

Method used

The design incorporates a combination of a clamping mechanism, a cooling mechanism, and a bottom support mechanism. The clamping mechanism provides clamping force through a bidirectional screw slide rail and an inner slide block, while the cooling mechanism sprays liquid to cool the pipes. The bottom support mechanism provides soft support to prevent slippage at the clamping position due to high temperatures. The cooling mechanism uses stirring fan blades to agitate the mixture of coolant and hard nanoparticles, increasing friction. The bottom support mechanism adjusts its height via a hydraulic rod to accommodate steel pipes of different diameters.

Benefits of technology

This effectively prevents slippage at high temperatures in the clamping position, ensuring that the steel pipe does not shake during traction and improving the thermal expansion effect.

Abstract

This utility model discloses a steel pipe heat expansion clamp to prevent swaying, comprising a base, an electric slide rail, a slider, and a base plate. The electric slide rail is fixed to the inner wall of the top of the base, the slider is movably connected to the electric slide rail, and the base plate is fixedly connected to the outer wall of the top of the slider. It also includes: a clamping mechanism fixedly connected to the outer wall of the top of the base plate for clamping one end of the steel pipe and providing a suction effect; a cooling mechanism fixedly connected to the outside of the clamping mechanism for spraying liquid to cool the clamped outer wall of the steel pipe; and a bottom support mechanism fixedly connected to the outer wall of the top of the base plate and conforming to the bottom outer wall of the steel pipe for providing soft support to the bottom of the steel pipe. This steel pipe heat expansion clamp to prevent swaying can avoid slippage at high temperatures at the clamping position, further preventing the steel pipe from swaying during traction.
