A rotary cutting and beveling machine

Abstract

The invention discloses a rotary cutting beveling machine. The rotary cutting beveling machine includes two automatic feeding copying tool posts, a telescopic transmission device, a telescopic guide track and a pushing rod mechanism, and the telescopic transmission device is installed on the telescopic guide track; the telescopic transmission device includes a sprocket-wheel case and a track trolley chain, the track trolley chain is formed by hinging a plurality of track trolleys end to end, the two automatic feeding copying tool posts are fixed to two of the track trolleys, a cutting tool isinstalled on one of the tool posts, and a beveling tool is installed on the other tool post; and the telescopic guide track includes a guide track body, a locking chain, a spring and a tensioning assembly. The rotary cutting beveling machine can meet the cutting beveling of all pipes of different diameters, completely realize cold cutting, and is extremely wide in use, all parts are connected by aquick tension mechanism, and disassembly and installation are convenient.

Description

technical field [0001] The invention relates to pipe cutting and beveling for petroleum, chemical industry, natural gas and other industries, in particular to a rotary cutting and beveling machine. Background technique [0002] With the demand for pipeline installation in various fields, higher requirements are put forward for the quality of pipeline installation. Pipeline installation mainly involves two major processes of cutting and welding. There are currently two cutting methods on the market, one is high temperature cutting; the other is cold cutting. Cutting; high-temperature cutting leads to material changes and shape changes of the pipe directly affect the subsequent welding quality; while cold cutting can meet the cutting and beveling in different environments, ensuring the subsequent welding quality, but the cold cutting tool currently on the market is a It is a split-type cutting and beveling machine, and the other is a pipe climbing machine; due to structural li...

[0002] With the demand for pipeline installation in various fields, higher requirements are put forward for the quality of pipeline installation. Pipeline installation mainly involves two major processes of cutting and welding. There are currently two cutting methods on the market, one is high temperature cutting; the other is cold cutting. Cutting; high-temperature cutting leads to material changes and shape changes of the pipe directly affect the subsequent welding quality; while cold cutting can meet the cutting and beveling in different environments and ensure the subsequent welding quality, but the cold cutting tool currently on the market is a It is a split-type cutting and beveling machine, and the other is a pipe climbing machine; due to structural limitations, the former needs to develop a series of matching customized products to cut pipes with different diameters, which cannot meet market demand; while the latter pipe climbing machine although It can meet the cutting of different pipe diameters, but it uses high-speed rotating blades to cut, which is prone to open flames, and it is difficult to meet the requirements of the environment without open flames
