Portable Tube or Bar End-Facing Unit

Abstract

The invention relates to the field of a portable pipe or rod processing device, and specifically discloses a portable pipe or rod end surface processing device, which includes a body for carrying various components; The clamping assembly of the bar; the cutting assembly arranged on the body for cutting the end face of the pipe or bar; the first drive assembly arranged on the body to drive one of the cutting assembly or the clamping assembly to rotate; arranged on the body, A second drive assembly for driving one of the cutting assembly or the clamping assembly toward and away from each other, capable of providing a substantially stable interaction between the cutting assembly and the clamping assembly as the cutting assembly and the clamping assembly move toward each other Forced flexible feed unit. The invention prolongs the service life of the cutting assembly, improves the processing efficiency by setting the flexible feeding unit, and the end surface of the workpiece after processing is regular and the pass rate is high.

Description

technical field [0001] The invention belongs to the field of pipe or bar cutting processing, and in particular relates to a portable pipe or bar end surface processing device. Background technique [0002] Liquid and gas pipelines are widely used in petroleum, chemical, power generation, pharmaceutical and other industrial fields. In production applications, pipeline reconnection is often required during early laying of pipelines, mid-term process optimization, and post-aging maintenance. Since the transmission medium has an important impact on production safety and the environment, the sealing and reliability of pipeline connections are particularly important. In order to improve the connection performance of the pipeline, it is usually necessary to chip or trim the end face of the pipeline to meet the requirements of the installation process. Confined to the laying, replacement and maintenance of pipelines, it is often at the production site, rather than in the machining...

AI Technical Summary

Problems solved by technology

The feed of the tool is realized by manually rotating the nut, so the force exerted by the tool on the end surface of the pipe is unstable and fluctuates greatly, resulting in instability of the real-time cutting amount; the instability of the real-time cutting amount will cause the following consequences: 1. When the real-time cutting amount is too much, the tool is easily stuck, which affects the processing efficiency, and what is more, the tool is damaged; 2. The wide fluctuation of the real-time cutting amount leads to short tool life; 3. The wide fluctuation of the real-time cutting amount also leads to The tool has a large jump relative to the central axis of the pipe, and the end face of the processed pipe is irregular, poor in sealing performance, and low in pass rate
