Description
Technical field
The present invention relates to welding technology field more particularly to a kind of plasma (orifice) gas planing systems for cement roller gouge.
Background technology
Plasma arc welding (PAW) refers to using the high-energy density line of plasma arc as the fusion welding method of welding heat source.Electricity
For arc after three kinds of mechanical compression effect, thermo-squeezing effect, pinch effect pinch effects, energy height concentrates on diameter very
In small arc column, the gas in arc column is ionized into plasma, therefore referred to as plasma arc.When nozzle diameter is smaller, gas
Body flow is larger and when increasing electric current, the speed that flame passes are sprayed from nozzle is very high, has a prodigious impact force, it is this it is equal from
Subarc is known as " harsh arc ", is mainly used for cutting metal.Conversely, when if arc-plasma current is smaller, impact force is smaller, Gai Dengli
Subarc is known as " flexible arc ", is mainly used for welding.Plasma gouge, refer to high temperature, high-speed flow plasma gas plane machine spray
When being sprayed at mouth, if having electric current to pass through between electrode and workpiece in nozzle, which will form high-temperature plasma electric arc,
The heat of electric arc makes local melting and the evaporation of the metal works of nozzle face, under the drive of high speed plasma air-flow, melting
Metal is excluded, and this processing method is known as plasma gouge.Cement roller press is the milling equipment of manufacture of cement.Cement rolled
The roller of machine situations such as roll surface will produce pit, bonding, abrasion in use, it is therefore desirable to which roller gouge and repair
It is multiple.When nozzle passes through the pit of roll surface, pit does not need to gouge, will wave if the pit of roll surface is more
Take big energy；Pit can make electrode elongated at a distance from workpiece simultaneously, to cause electric arc unstable, increase the several of current interruption
Rate.And if roll surface bonds sundries, the electric currents between electrode and workpiece such as cement and just will disconnect, to cause current interruption.Due to
Roller is rotation during by gouge, if cannot find in time after nozzle current interruption, it is also necessary to be inverted to roller, with determination
Roller stops the position of gouge.If nozzle is stopped, then when to nozzle again striking, since gouge striking is to voltage, gas
That presses is more demanding, therefore the time expended is more.

Promoting the circulation of qi is dug, the range information for being used to acquire nozzle and roll surface apart from detection module, and the arc-striking module is used to be gouge mould
Block striking, the current or voltage adjustment module are used to be converted into using for gouge module and arc-striking module by extraneous alternating current
Direct current, and the size of the current or voltage of circuit where adjusting gouge module and arc-striking module, gas supplying module are used for
Air source is provided to gouge module and arc-striking module, gouge module, apart from detection module, arc-striking module, electric current or the regulation of electrical circuit mould
Block, gas supplying module and control module are electrically connected, and reference distance value is arranged in control module, will be collected apart from detection module
Nozzle and roll surface distance signal transmission to control module, control module generates the distance signal acquired apart from detection module
Real-time range value, when real-time range value be more than reference distance value when, control module by control current or voltage adjust module with
And gas supplying module carries out current interruption to gouge module, makes gouge module from service, and arc-striking module is made to work；When in real time away from
When being less than or equal to reference distance value from value, control module starts gouge module, and is gouge module striking by arc-striking module,
Gouge module is set to generate high-temperature plasma electric arc, to carry out gouge to the roll surface of roller.
Advantageous effect：The plasma (orifice) gas planing system for cement roller gouge of the present invention includes gouge module, distance detection
Module, arc-striking module, current or voltage adjustment module, gas supplying module, control module.When detecting spray apart from detection module
When mouth and the real-time range value of cement roller surface are more than the reference distance value of control module, control module closes gouge module, draws
Arc module is in starting state, while control module is also turn off the first air compressor of gas supplying module, to stop being
Gouge module supplies, to reduce the consumption of electric energy and compressed gas；When detecting nozzle and cement roller apart from detection module
When the real-time range value on surface is less than or equal to the reference distance value of control module, control module starts gouge module and the first sky
Air compressor, since arc-striking module is constantly in starting state, under the action of the high-temperature plasma air-flow that arc-striking module generates, greatly
The big difficulty for reducing cement roller surface and generating electric arc with electrode is promoted so as to enable gouge system non-stop run
