Steel pipe installing and expanding equipment with high-temperature heating and remodeling functions

Abstract

The invention discloses steel pipe installing and expanding equipment with high-temperature heating and remodeling functions. The equipment comprises a base. The base is provided with a baffle, a transition rail, a rotating clamping device, a guide rail and a telescopic cylinder in sequence from left to right. A sliding block is movably connected to the guide rail. One end of the sliding block is connected with the output end of the telescopic cylinder. A number one motor is fixedly connected to the sliding block. An output shaft of the number one motor is connected with an expansion die through a coupler. A steel pipe is fixedly connected to the rotating clamping device and a clamping plate. The number one motor and the telescopic cylinder are matched to enable the expansion die to rotate while advancing, and the expansion speed of the steel pipe is increased; similarly, the phenomenon that the expansion die gets stuck in the steel pipe is avoided, the steel pipe rotates reversely under driving of a number two motor, and a spray gun is matched, so that the part, to be expanded, of the steel pipe is heated, the crystal structure in the part, to be expanded, of the steel pipe is changed, expanding is easier, and burst of the steel pipe is avoided.

Description

technical field [0001] The invention relates to a tube expansion device, in particular to a tube expansion device for installing a steel pipe with the function of heating and reshaping at a high temperature. Background technique [0002] At present, some steel pipe processing and production enterprises, when connecting large-diameter pipes and small-diameter pipes, usually expand the mouth of the small-diameter pipe end to the pipe diameter of the large-diameter pipe, and complete the transition connection from the large-diameter pipe through welding. In the existing steel pipe expansion device, its structure is complex, the labor intensity is high, time-saving and labor-saving, and the work efficiency is low, which affects the production efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a steel pipe installation expansion equipment with high-temperature heating and reshaping function, so as to solve the problems raised in th...
