Description
Technical Field
The utility model relates to a plasma electrode cutting torch belongs to plasma cutting nozzle technical field.
Background
The plasma electrode cutting nozzle is an important component of a plasma cutting machine and plays an important role in the cutting quality of a workpiece.
The existing plasma electrode cutting nozzle is to process an electrode hole at the center of the end face of an electrode, the diameter of the electrode hole is smaller than that of a hafnium wire to be loaded, the hafnium wire and the electrode hole form interference fit, because the outer diameter of the hafnium wire is larger than the aperture of the electrode hole, the hafnium wire is difficult to install, for example, a specific tool is needed to press the hafnium wire into the electrode hole directly during specific installation, or the plasma electrode cutting nozzle and the hafnium wire are welded into a whole by brazing, because the outer diameter of the hafnium wire is larger than the aperture of the electrode hole of the electrode cutting nozzle, the two modes can cause low production efficiency, the quality of the pressed product is unstable, the service life of the product is influenced, the product needs to be replaced within 3 to 4 hours generally, therefore, the processing cost of the plasma electrode cutting nozzle is high, the processing efficiency is low, and the improvement of the processing efficiency and the service life of the products through technical improvement is urgently needed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses not enough to prior art exists provides a simple structure, and processing is convenient, and the processing cost is low, and machining efficiency is high, and the stable plasma electrode cutting torch of processing product.
The utility model provides an above-mentioned technical problem's technical scheme as follows: a plasma electrode cutting nozzle comprises an electrode cutting nozzle body and a hafnium wire installed on the electrode cutting nozzle body, wherein an electrode hole is formed in the free end of the electrode cutting nozzle body, the outer diameter of the electrode hole is larger than that of the hafnium wire, a gap is formed between the hafnium wire and the electrode hole, brazing filler metal is filled in the gap, and the hafnium wire is installed in the electrode hole in a brazing mode through a welding tool; the welding tool comprises an electrode chuck and a power supply, the electrode chuck is connected with the power supply through a circuit, and the electrode chuck clamps the electrode cutting torch body and performs electric heating on the hafnium wire and welding on the electrode cutting torch body.
The utility model has the advantages that: the external diameter of hafnium silk is less than the aperture in electrode hole, the installation and the location of the hafnium silk of being convenient for, and the brazing filler metal of also being convenient for simultaneously fills in between the gap of hafnium silk and electrode hole, and the brazing filler metal between hafnium silk and the electrode hole is convenient for weld the frock and welds between hafnium silk and the electrode cutting torch. In a word, the utility model discloses hafnium silk simple to operate is swift, and the location is stable, and the welding is simple between hafnium silk and the electrode cutting torch, and machining efficiency is high, and the processing cost is low, and the product quality after the processing is stable, has prolonged the life of product.
On the basis of the technical scheme, the utility model discloses can also do following improvement.
Further, the electrode hole is arranged in the center of the free end face of the electrode cutting torch body.
Adopt the beneficial effect of above-mentioned further scheme to be, the installation of hafnium silk is put at the central point of electrode cutting torch, the operation of the follow-up plasma electrode cutting torch of being convenient for.

Detailed Description
The principles and features of the present invention are described below in conjunction with examples, which are set forth only to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1 and 2, a plasma electrode cutting nozzle comprises an electrode cutting nozzle body 2 and a hafnium wire 1 mounted on the electrode cutting nozzle body, wherein an electrode hole 3 is formed in a free end of the electrode cutting nozzle body, an outer diameter of the electrode hole 3 is larger than an outer diameter of the hafnium wire 1, a gap is formed between the hafnium wire and the electrode hole, brazing filler metal is filled in the gap, and the hafnium wire is mounted in the electrode hole through brazing by a welding tool; welding frock includes electrode holder 5 and power 4, electrode holder 5 through the circuit with power 4 is connected, electrode holder 5 is cliied electrode cutting torch body ohmic heating is right the hafnium silk with the electrode cutting torch body welds.
The electrode hole 3 is arranged at the center of the free end surface of the electrode cutting torch body. The hafnium wire is arranged at the central position of the electrode cutting nozzle, so that the subsequent plasma electrode cutting nozzle operation is facilitated.
The working process is as follows: the method comprises the steps of firstly drilling a hole in the center of the free end face of a plasma electrode cutting nozzle, enabling the aperture of a drilled electrode hole to be larger than the outer diameter of a welding wire to be filled, namely a hafnium wire, then filling the hafnium wire into the electrode hole, enabling a gap to exist between the hafnium wire and the electrode hole, then filling brazing filler metal for welding into the gap between the hafnium wire and the electrode hole, then clamping an electrode chuck 3 of a welding tool to the electrode cutting nozzle 2, starting a power supply of the welding tool, and conducting heating, so that the hafnium wire and the electrode cutting nozzle are welded into a whole. Because the external diameter of hafnium silk is less than the aperture in electrode hole, so can with electrode cutting nozzle welding stability and efficient through the hafnium silk after the brazing, the welding yield is high, the long service life of product.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
