Pipe opening shaping device for high-pressure oil pipes

Abstract

The invention discloses a pipe opening shaping device for high-pressure oil pipes, and mainly relates to the technical field of pipeline shaping devices. The pipe opening shaping device comprises a pipe feeding unit, a pipe receiving unit, a first shaping unit, a second shaping unit and a control unit, wherein the pipe feeding unit is arranged at the rear side of the pipe receiving unit; and the first shaping unit and the second shaping unit are separately arranged at two ends of the pipe receiving unit in a sliding manner. According to the pipe opening shaping device for the high-pressure oil pipes, the pipe receiving unit is provided with a plurality of U-shaped grooves and a pipe receiving column to be matched with a sleeve with notches, and a plurality of high-pressure oil pipes can be received at a time, so that it is guaranteed that the pipe receiving column and the sleeve rotate in a staggered manner without pipe leakage, it is guaranteed that the pipes are sequentially discharged during discharging, and it is guaranteed that all the shaped high-pressure oil pipes stably fall and do not impact one another; and the first shaping unit and the second shaping unit are matched with electric heating plates and heat conducting rods through conical rods, so that two ports of the plurality of high-pressure oil pipes can be subjected to hot extrusion shaping synchronously, and rebounding is avoided after shaping.

Description

technical field [0001] The invention relates to a pipeline shaping device, in particular to a high-pressure oil pipe mouth shaping device. Background technique [0002] The high-pressure oil pipe is an integral part of the high-pressure oil circuit. It is required that the high-pressure oil pipe itself needs to withstand a certain oil pressure and have a certain fatigue strength to ensure the sealing requirements of the high-pressure oil circuit. In the high-pressure oil circuit, due to the high pressure, there will often be leakage at the connection between the high-pressure oil pipe and the pipe joint. Once the two are not in place, leakage will inevitably occur under high pressure. For the sake of sealing requirements, the high-pressure oil pipe will be in use. Previously, the pipe joints were press-fitted on both ends of the high-pressure oil pipe to complete the crimping of the high-pressure oil pipe. However, in general, the high-pressure oil pipe, especially the rubbe...
