AI Technical Summary

Technical Problem

Existing seamless steel pipe cutting equipment suffers from severe smoke and dust pollution, molten slag splashing, and low cutting accuracy. Furthermore, it lacks effective enclosure protection and positioning structures, making it difficult to meet the requirements for efficient, clean, and high-precision cutting.

Method used

The system employs a closed top and bottom cover structure, along with a positioning seat and a smoke and slag removal system, to achieve the separation of smoke and molten slag. The elastic positioning structure ensures the stable positioning of the steel pipe, forming a fully enclosed cutting cavity.

Benefits of technology

It effectively blocks arc light, high-temperature splashes and smoke leakage, enables the classified collection of smoke and slag, improves cutting accuracy and operational safety, and ensures the stability and cleanliness of the cutting process.

Abstract

This invention relates to the field of plasma cutting technology, specifically to a high-efficiency cutting device and method for seamless steel pipes. The device includes a worktable with a rotating chuck on one side and multiple conveyor seats on the other. A slag discharge port is provided on the worktable, with a horizontal moving component and a vertical moving component on one side of the port. A plasma cutter is mounted on a vertical frame. A top cover is located at the lower end of the plasma cutter, and a bottom cover is located below the steel pipe. The top cover has a smoke exhaust pipe, and the bottom cover has a slag discharge channel at its bottom. Bottom positioning seats are located on both sides of the bottom cover, and top positioning seats are located on both sides of the top cover. This invention achieves separation of smoke and slag through the closed bottom and top covers. Combined with the bottom and top positioning seats, it solves the problems of smoke leakage, slag splashing, and unstable steel pipe positioning, thus improving cutting accuracy and environmental friendliness.
