A flame cutting device

Abstract

The invention provides a three-gun flame cutting device at least comprising a first flame cutting gun head, a second flame cutting gun head and a third flame cutting gun head. The first flame cutting gun head is arranged on the next working position of the second flame cutting gun head; the third flame cutting gun head is located on the previous working position of the second flame cutting gun head. The cutter enables the preheating flame area and the cutting speed to be adjusted according to the material and the thickness of steel plates, thereby realizing portable multifunctional intermittent cutting. The risk of cutting crack of the steel is controlled and the technology and equipment guarantee is provided for stable production of high quality products.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a three-gun flame cutting device. Background technique [0002] With the rapid development of wide and thick plate production technology at home and abroad, the quality risk of fire-cut cracking of high-quality, high-strength special products such as wear-resistant steel, high-strength steel, die steel, high-carbon steel and high-alloy steel, such steel usually has Due to the high carbon equivalent and strong crack sensitivity, the steel plate is prone to cracking when it is cut by flame, especially in winter and rainy seasons. In order to ensure the stable production of such products, the development of innovative fire-cutting equipment and its process technology is particularly urgent. [0003] figure 1 As a typical traditional manual flame cutting machine, the flame cutting machine only has a flame cutting gun head, which can realize the cutting of steel plat...

AI Technical Summary

Problems solved by technology

This type of flame cutting machine can only cut the steel plate to a fixed length, and cannot realize the preheating and postheating functions of the easy-to-crack steel plate, and the product is prone to cracking after cutting

[0004] In actual production, it is often encountered that if the easy-to-crack steel plate is preheated before flame cutting, this will inevitably cause excessive energy consumption, and the high temperature of the entire steel plate cannot be used for normal portable operation and cutting. At the same time, it is necessary to invest in a new special preheating device. Cause problems such as high production costs

[0005] In order to overcome the above problems, it is necessary for multiple people to use special equipment to preheat the easy-to-crack steel plate simultaneously before and after the flame cutting, which will cause a great waste of manpower and financial resources. Heat, the precise control of temperature and the accuracy of its position will have a certain impact, which will directly affect the uniformity of steel plate properties
