Embodiment Construction

[0048]Flame cutting of steel (also called oxygen cutting) is to use gas flame (hereinafter referred to as preheating flame) to heat the surface of steel to the ignition point and form an activated state, and then send high-purity, high-flow cutting oxygen to make the steel The iron in the oxygen atmosphere burns to generate iron oxide slag and releases a lot of heat at the same time. With the help of these combustion heat and slag, the lower layer of steel and the front edge of the cut are continuously heated to reach the ignition point until the bottom of the workpiece. At the same time, the momentum of the cutting oxygen flow blows off the slag, thereby forming an incision to cut the steel. Therefore, from a macro perspective, oxygen cutting is a processing method that combines the chemical process of burning iron in steel (in a broad sense, metal) in high-purity oxygen and the physical process of removing slag by cutting oxygen flow.

Abstract

The invention discloses a cutting device which comprises a cutting gun body and a cutting nozzle. The cutting nozzle comprises a cutting nozzle core and a cutting nozzle sleeve. The cutting nozzle core comprises a nozzle core body, a cutting oxygen passage, a first boss, a first preheating hole, a second preheating hole and a preheating tank. The cutting nozzle sleeve comprises a nozzle core fitting hole, the cutting nozzle core is fitted in the cutting nozzle sleeve, and the cutting nozzle core and the cutting nozzle sleeve serve as a whole to be fitted in the cutting gun body. The cutting gun body comprises a gas pipe, a preheating oxygen pipe and a cutting oxygen pipe. The cutting oxygen pipe is communicated with the cutting oxygen passage of the cutting nozzle core. The cutting device has the advantages that the flame is concentrated, the cutting speed is quick, the section is smooth and clean, the kerf is narrow, and steel is reduced. In addition, the cutting device is energy-saving, free of dark smoke during cutting, environment-friendly and low in noise.

Description

[0001] This application is a divisional application of the patent application whose application number is 201010533327.7 and the invention name is cutting device. technical field [0002] The invention relates to a cutting device, in particular to a flame cutting device for cutting workpieces, which can be used for billet segmentation, pipe cutting, stainless steel cutting, etc. produced in iron and steel plants, and belongs to the category of cutting tools. Background technique [0003] Currently, workpiece cutting tools include plasma cutting devices, laser cutting devices and flame cutting devices. Flame cutting device is a kind of cutting equipment that uses gas with oxygen or gasoline with oxygen to cut metal materials. Compared with laser cutting, flame cutting device is far inferior to laser cutting machine in terms of cutting speed accuracy and cutting material types, but in cutting Both thickness and cutting cost are far superior to laser cutting machines. Compared...
