Abstract
The utility model provides a plasma cutting nozzle. The plasma cutting nozzle comprises a nozzle lower body and a nozzle upper body. The nozzle lower body is of a barrel-shaped structure, wherein the two ends of the barrel-shaped structure are opened. The nozzle upper body is of a cone structure, the cone structure is composed of an outer conical surface and an inner conical surface, the inner diameter of the bottom end of the cone structure is same as the inner diameter of the nozzle lower body, the bottom end of the cone structure is connected with one end of the nozzle lower body, an airflow outlet is formed in the top end of the cone structure, and the inner conical surface is a curved surface. A bus of a cone inside the airflow outlet is changed to a curve, so that the speed and the direction of airflow are not greatly changed at the intersection point of the cone and the outlet, the direction of the airflow gradually changes along the outline of the nozzle, therefore, transition is stable, plasma beams are stably concentrated, the quality of the plasma beams is improved, plasma cutting quality is improved, the service life of easily-damaged parts is prolonged, and the plasma cutting nozzle can be widely applied to a plasma cutting system.
Description
Technical field
The utility model relates to a kind of plasma cutting part, particularly, relates to a kind of plastic cutting burner.
Background technology
The plasma cutting utilizes the heat of high-temperature plasma electric arc to make metal local melting and the evaporation of workpiece incision, and borrows the isoionic momentum of high speed to get rid of motlten metal to form a kind of processing method of otch.Plasma cutting system mainly is comprised of feeder, power supply and burning torch, plasma cutting tool has that cutting thickness is large, cutting flexibly, clamping workpiece is simple and can cutting curve etc. advantage, can be widely used in the cutting of all metal materials and Fei Jin bits material.
In the outlet of the nozzle of existing plasma cutting system, one section taper seat is arranged; outer surface also has one section taper seat; plasma (orifice) gas and protection gas flow from circular cone is export-oriented; at the intersection airflow direction, be changed significantly; the speed of air-flow and the sudden change of direction can cause the uncertainty of beam-plasma, affect the stability of beam-plasma, have reduced the quality of plasma cutting; shortened the life-span of consumable accessory, as depicted in figs. 1 and 2.
Therefore, research and develop a kind of novel plastic cutting burner and seem particularly necessary.
The utility model content
