Pipe expanding machine capable of carrying out clamping

Abstract

The invention relates to a pipe expanding machine capable of carrying out clamping. The pipe expanding machine capable of carrying out the clamping comprises a machine frame and a power distribution control box, wherein a pipe expanding and carrying device is arranged on the machine frame, the pipe expanding and carrying device comprises a material carrying pipe expanding device, the lower part ofthe material carrying pipe expanding device is connected with a material carrying rotating shaft, and the material carrying rotating shaft is connected to a pipe expanding rotating motor; and the material carrying pipe expanding device comprises a material carrying rotating base, material carrying fixing sliding blocks are arranged on the material carrying rotating base through material carryingfixing bolts, pipe expanding movable arc blocks are uniformly arranged on the material carrying rotating base, each pipe expanding movable arc block comprises a fan-shaped block and an arc-shaped column plate, wherein the fan-shaped blocks of pipe expanding moving grooves are matched with the material carrying fixing sliding block, and the arc-shaped column plates are arranged on the outer sides of the fan-shaped blocks; and the lower part of the arc-shaped column plates are matched with a pipe expanding and pulling device. The adopted pipe expanding and carrying device is matched with the pipe expanding and pulling device to realize the expansion of a pipe opening, the pipe expanding and carrying device is used for expanding the pipe sleeving the pipe expanding movable arc blocks throughexpansion of the plurality of rotating pipe expanding movable arc blocks, the pipe can be prevented from being deviated from the center of the pipe in the whole pipe expanding process, and the pipe after pipe expanding can be prevented from being clamped.

Description

[0001] Original application number: 2017107259218 [0002] Applicant of the original case: Dongguan Ronggong Automation Technology Co., Ltd. [0003] Date of original filing: August 22, 2017 [0004] Original application name: an automatic pipe expanding machine. technical field [0005] The invention relates to the field of pipe processing equipment, in particular to a pipe expander capable of clamping. Background technique [0006] During the layout of the pipeline, if the pipeline is not long enough and needs to be butted, the usual method is to use a direct joint to connect two straight pipes to each other, and then weld them to death after the butt joint is completed, but the stress at the weld is relatively concentrated. Welds are prone to weld cracking, which causes leakage. Therefore, in order to reduce the number of welds, the existing method is to expand one of the pipes, insert the other pipe into the expanded pipe, and then Butt welding is performed, compared ...

Problems solved by technology

[0007] Most of the existing pipeline expansion is manually operated, and the extrusion of the expansion head is used to realize the expansion of the pipeline. The manual operation is inefficient and time-consuming. Therefore, some automatic expansion equipment has appeared. The existing expansion equipment Most of them fix the product, and then push the expansion head into the pipe hole through the pushing device to realize pipe expansion. However, there are big problems in the existing pipe expansion equipment, and it is easy to cause the expansion head to be separated from the pipe during the insertion process. If the pipe is not concentric, it will lead to eccentricity of the pipe head after pipe expansion, and there will also be a situation where the pipe expansion is stuck
