Abstract
The utility model relates to a component of a plasma cutting device, in particular to a plasma cutting electrode, eliminates the constriction resistance and the gap resistance existing inside the present plasma cutting electrode and improves radiating effect and conductivity of the electrode. The technic proposal is that the plasma cutting electrode comprises an electrode housing, a hydrocooling outer casing and an electrode core, and is characterized in that the hydrocooling outer casing is a silver prismatical monomer of a hole cut on the axle center, wherein, the inside of the axle center hole has an electrode core which is hafnium filament. The hafnium filament and the hydrocooling outer casing, and the hydrocooling outer casing and the electrode housing are both connected by fusion and braze welding. The utility model is mainly applied in a plurality of plasma cutting devices.
Description
One, technical field
The utility model relates to the parts of plasma cutting machines, particularly the plasma cutting electrode.
Two, background technology
The cutting torch electrode of plasma cutting machines, it is a kind of attrition component, from the equipment of external introduction, its plasma cutting electrode must be bought as annex, and cost is very high, by being dissected, state's external electrode finds, its water cooling overcoat adopts copper Unionpay to close the shroud ring overcoat, and this water cooling overcoat is that copper sheathing seat, silver-colored body and hafnium filament core three cooperate composition with the axis body mechanical compaction, when heavy current is passed through, there are two bed boundary contact resistances and gap thermal resistance, make radiating effect and conductive effect not good enough.
Three, summary of the invention
The utility model technical issues that need to address are: cancel outside copper sheathing seat, eliminate inner two bed boundary contact resistances of plasma cutting electrode and gap thermal resistance, improved electrode radiating effect and electric conductivity.Technical solution is: the plasma cutting electrode, comprise electrode shell, water cooling overcoat, electrode cores, it is characterized in that: the water cooling overcoat is the silver column monomer of axle center perforate, electrode cores is arranged in the axle center hole, electrode cores is a hafnium filament, and hafnium filament all adopts the soldering fusion to be connected with water cooling overcoat, water cooling overcoat with electrode shell.The beneficial effects of the utility model are: owing to adopt the water cooling overcoat instead of copper Unionpay of pure white silver-colored column monomer structure to close shroud ring water cooling overcoat, make the heat-sinking capability and the conductive capability of water cooling overcoat better, and adopt the soldering fusion process that electrode shell, water cooling overcoat, electrode cores are become one, not only eliminate the gap thermal resistance, further improved the heat-sinking capability of water cooling overcoat.And, do not have the contact resistance of electrode self because of contactless gap, promptly eliminated the thermal source of self-resistance thermosetting, the temperature rise when having reduced electrode work.And because hafnium filament runs through the water cooling overcoat, guaranteed the end cooling of hafnium filament, and prolonged the service life of hafnium filament.
Four, appended drawings is the utility model structural representation
Five, the specific embodiment
With reference to accompanying drawing, the plasma cutting electrode, the pure white silvery of water cooling overcoat 2 usefulness is done, column monomer for the axle center perforate, wire electrode core 3 is arranged in the axle center hole, electrode cores 3 is a hafnium filament, and hafnium filament runs through water cooling overcoat 2, and hafnium filament all adopts the soldering fusion to be connected with water cooling overcoat 2, water cooling overcoat 2 with electrode shell 1.During electrode work, inner cooling water can more effectively reduce hafnium filament residing temperature when cutting, prolongs the service life of electrode.Be mainly used in multiple plasma cutting machines.
Claims (3)
1, a kind of plasma cutting electrode comprises electrode shell, water cooling overcoat, electrode cores, it is characterized in that: the water cooling overcoat is the silver column monomer of axle center perforate, and electrode cores is arranged in the axle center hole.
2, plasma cutting electrode according to claim 1, it is characterized in that: electrode cores is a hafnium filament, runs through the water cooling overcoat.
