Technical field
The present invention relates to plasma cutting technique field, specifically a kind of non-high frequency plasma cutting gun.
Background technology
In existing non-high frequency plasma cutting gun, due to piston rod and electrode contact section be subjected to prolonged high temperature,
Easy deformation of feeling like jelly.
In addition, now generally using the mounting means of integral type to non-high frequency plasma cutting gun, i.e. piston rod can only be from work
The top of plug cavity enters in piston cavity and down installed, and result in the chi of one end (i.e. bottom) that piston rod is connected with electrode
It is very little to beat the size of piston inside cavity, otherwise have influence on installation and the function of the structure of insulating materials and miscellaneous part.
The content of the invention
Increase the mechanical strength of piston rod head it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of,
Original piston rod is reduced due to seizure of piston failure caused by deformation, non-high frequency for the practical difficulty that accessory can not be changed etc. from
Sub- cutting gun.
In order to achieve the above object, the invention provides a kind of non-high frequency plasma cutting gun, including electrode, piston cavity
And piston rod, the piston rod is flexibly connected in piston cavity, and the electrode is assemblied in the bottom of the piston rod, the piston
The bottom outer circumferential of bar forms one and encloses boss.The piston rod is used for connection electrode, and the electrode is plasma electrode, piston
Bar is arranged on the center of whole pipette tips as energy source pathway.The piston cavity is the main part of cutting gun, for forming work
The up and down space of stopper rod.
Preferably, the bottom of described piston cavity forms one and encloses groove, and the groove matches with the boss to be agreed with,
Contact surface is formed between the recessed deep gouge and boss.The groove is used cooperatively with boss so that between piston rod and piston cavity
That agrees with is more preferable, moves more smooth.
Preferably, form one in the bottom of the piston rod and enclose escape.
Preferably, the height h of described boss is 1-2.5mm；
The depth d of described deep gouge is 1-2.5mm；
The external diameter of described piston rod bottom is 8-9.5mm.
Preferably, the head of described piston rod is arranged ring installation.The piston ring is located at the head of piston rod, makees
For the support member of piston rod.
Preferably, described piston ring is connected with the piston rod for interference fit.
Preferably, described piston ring is to be threadedly coupled with the piston rod.
Preferably, the head of described piston ring forms one and encloses step, is arranged piston ring and baffle ring successively on the step.
Preferably, the bottom of described piston rod forms blind hole, and the blind hole has internal thread；
External screw thread is formed on the electrode；
The electrode is to be threadedly coupled with piston rod.
The invention also provides a kind of assembly method of non-high frequency plasma cutting gun, the assembly method utilizes above-mentioned
Non- high frequency plasma cutting gun, comprises the following steps：
Step a. piston rods are fitted into the piston cavity from the bottom of piston cavity；
Step b. piston rings are fitted at the top of piston cavity in the piston movement cavity, and are arranged installed in described
The head of piston rod；
Step c. springs are fitted at the top of piston cavity in the piston cavity, and are set in the piston rod
Head；
Step d. piston caps are arranged on the head of the piston cavity.
The beneficial effects of the invention are as follows, stretch out in the bottom of the piston rod of piston cavity have it is bigger than like product straight
Footpath, with higher intensity, will not be deformed by after external impacts and cutting heating because of bottom, reduce due to mechanical damage band
Come piston rod bottom deformation and have influence on electrode large assembly, while avoiding due to cumulative errors and insulating materials Zona transformans
The size come is inconsistent, solves other products and relies on the problem of electrode or insulating materials are to complete positioning.By piston rod head
Size is promoted to 8-9.5mm by original 6-7mm (diameter of screw thread is M5), it is to avoid hold because the threaded walls of original piston rod are thin
Piston rod head deformation caused by easily or sliding tooth；Due to equivalent to the wall thickness for adding piston rod end, it is to avoid due to falling
The deformation brought etc. mechanical damage；Material softening after being generated heat due to long-time cutting is avoided to cause interrupted above and below piston and burn
Pipette tips.The assembly method changes compared to conventional traditional technology mode that integral type installation is down carried out by piston cavity top
Enter for split type assembling mode, piston rod is fitted into piston cavity from the bottom of piston cavity, increasing can be met
The requirement of the size of the end of the piston rod of connection electrode.One-piece piston bar can only be installed from top to bottom, result in piston rod
Head sizes can not be excessive, otherwise has influence on installation and the function of the structure of insulating materials and miscellaneous part, and it is newly-designed from
Under the piston rod head larger that can make of mounting means up, meet the demand of actual use.
