Description

Technical Field

[0001] The utility model belongs to the technical field of plasma cutting equipment, and in particular relates to a plasma cutting gun. Background Art

[0002] Plasma cutting gun is a processing method that uses the heat of high-temperature plasma arc to partially melt the metal at the cut of the workpiece, and uses the momentum of high-speed plasma to discharge the molten metal to form a cutting seam. It is widely used due to its advantages such as fast cutting speed, high cutting accuracy, and easy setting of cutting conditions.

[0003] In the past, the conductor wire of plasma cutting guns was generally made of copper wire. However, the price of pure copper is relatively high, which makes the cost of plasma cutting guns relatively high. In addition, the density of pure copper is large, which makes it heavy to drag the cable during cutting, especially when hand-held cutting, which affects the cutting efficiency. Utility Model Content

[0004] In order to overcome the above technical problems, the utility model provides a plasma cutting gun, which reduces the production cost and improves the convenience of cutting.

[0005] The utility model adopts the following technical solutions:

[0006] A plasma cutting gun comprises a grip, wherein the front end of the grip is connected to a gun head, and the rear end of the grip is connected to a cable connected to a chassis, wherein the interior of the cable comprises a high-pressure air pipe and a negative electrode wire, wherein the wire in the negative electrode wire has two layers, the inner layer is an aluminum wire core, and the outer layer is a copper wrapping layer.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] In the utility model, the conductor wire in the cable adopts a structure of an outer layer of copper and an inner layer of aluminum. The copper-clad aluminum wire has the composite characteristics of copper's conductivity and aluminum's low density. While ensuring the conductive performance, the cost is lower than that of copper wire, which can reduce production costs and reduce the overall weight of the plasma cutting gun. It is more convenient to drag and move during cutting work, thereby improving welding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. Unless otherwise specified, the raw materials and equipment used can be purchased from the market or are commonly used in the art. The methods in the embodiments are conventional methods in the art unless otherwise specified. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0013] A plasma cutting gun comprises a handle 2, the front end of which is connected to a gun head 1, the gun head 1 comprises a porcelain mouth, a nozzle, a flow divider and an electrode, the handle 2 is provided with a switch, the rear end of which is connected to a cable 3 connected to a chassis and an air source, the interior of the cable 3 comprises a high-pressure air pipe and a negative electrode conductor 4, the wire in the negative electrode conductor 4 comprises an inner and outer layer, the inner layer is an aluminum wire core, and the outer layer is a copper sheathing layer.

[0014] A plasma cutting gun, when used:

[0015] The use process of the device is no different from that of the existing plasma cutting gun. First, correctly connect the cable 3 of the cutting gun, and then perform the cutting work. The negative electrode wire 4 with an outer layer of copper and an inner layer of aluminum effectively reduces the cost of the argon arc welding gun, and the negative electrode wire 4 is lighter in weight, making it easier to drag and move the cable 3, thereby improving welding efficiency.

[0016] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the above embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
