Embodiment Construction

[0051] In the following description, various embodiments of nozzles are described which have at least one liquid inflow channel (referred to here as coolant inflow channel) and at least one liquid return channel (here referred to as coolant return channel), in particular There are exactly one each and exactly two each. But the present invention is not limited to this. There may be a greater number of liquid inflow slots and liquid return slots, and / or the number of liquid inflow slots and liquid return slots may be different.

[0052] figure 1 The plasma torch head 1 shown in FIG. 1 receives an electrode 7 with an electrode receptacle 6 in the present case via a thread (not shown). The electrodes 7 are designed as planar electrodes. Air or oxygen, for example, can be used as plasma gas (PG) for the plasma gun. The nozzle 4 is received by a substantially cylindrical nozzle holder 5 . A nozzle cover 2 fixed to the plasma torch head 1 via threads (not shown) fixes the nozzle...

Abstract

A nozzle for a liquid-cooled plasma torch, comprising a nozzle bore for the exit of a plasma gas jet at a nozzle tip, a first portion, the outer surface of which is substantially cylindrical, and a second portion adjacent thereto towards the nozzle tip, the outer surface of which tapers substantially conically towards the nozzle tip, wherein at least one liquid supply groove and / or at least one liquid return groove is / are provided and extend over the second portion in the outer surface of the nozzle (4) towards the nozzle tip, and wherein the liquid supply groove or at least one of the liquid supply grooves and / or a liquid return groove or at least one of the liquid return grooves also extends / extend over part of the first portion, and there is in the first portion at least one groove which communicates with the liquid supply groove or at least one of the liquid supply grooves or with the liquid return groove or at least one of the liquid return grooves.

Description

technical field [0001] The invention relates to a nozzle for a liquid-cooled plasma torch and a plasma torch head with the nozzle. Background technique [0002] The highly heated, electrically conductive gas is called a plasma, and it includes positive and negative ions, electrons, and excited and neutral atoms and molecules. [0003] Various gases are used as plasma gas, for example monoatomic argon and / or diatomic gases hydrogen, nitrogen, oxygen or air. These gases are ionized and dissociated by the energy of the arc. The arc converging through the nozzle is called the plasma jet. [0004] The parameters of the plasma jet can be greatly influenced by the shaping of the nozzle and electrodes. These plasma beam parameters are, for example, beam diameter, temperature, energy density and gas flow rate. [0005] In plasma cutting, for example, the plasma is constricted by a gas-cooled or water-cooled nozzle. From this it is possible to reach up to 2×10 6 w / cm 2 energy d...
