Description
Technical field：
The utility model is related to cold welding machine technical fields.
Background technology：
Precise cold soldering equipment is widely used in mechanical processing and maintenance work, using charging capacitor, with 10-3~10-1Second
Period, 10-6~10-5Second ultra-short Time electric discharge, make electrode material and the transient heating of workpiece contact site to 8000~
It 10000 degrees Celsius, to make wlding spread infiltration to base material, forms diffusion layer and realizes high strength bond, metal, casting can be repaired
The surface defects such as crackle, pit, abrasion, scuffing, stomata, the trachoma on surface.
For precise cold soldering equipment since discharge time is extremely short compared with the inter-spike intervals time next time, heat can pass through workpiece base
Body is spread, and working position not will produce heat aggregation, therefore the advantage for having heat-affected zone small；But it was operated continuously for a long time
Still inevitably will appear the case where workpiece bulk temperature rises in journey, this can reduce the efficiency of processing stand heat diffusion,
And then because material crystals institutional framework change caused by before and after working position physical property difference, to the consistency of performance of workpiece
It adversely affects.
Gas shield often is done using argon gas when processing is compared with active metal at present, but corresponding argon gas protects equipment
Do not have the temperature control capability to workpiece.Increase traditional compressor refrigeration system to be then intended to protect for cold welding machine gas
Device increases liquid channel system, and complicated and weight is big, and applicability is poor.
Invention content：
In consideration of it, it is necessary for the gas shielded device that precise cold soldering equipment designs a set of temperature controllable, gas shielded is made to fill
The control that can be achieved at the same time to work pieces process point actual temperature is set, and the gas to match is provided and protects electrode.
Have the gas shielded precision cold welding system of intermittent demagnetization cooling device, including：Cooling piston cylinder assembly and cold welding
Electrode assembly.
Wherein, cooling piston cylinder assembly includes cooling piston cylinder, magnetic cold core, magnetic cold core driving coil group, cold end piston, heat

When work, cold end piston carries out reciprocating action with hot junction piston in cooling piston cylinder, while magnetic cold core drives line
Circle group is put with switching electric drive magnetic cold core, is absorbed heat, and detailed process is：
Original state, cold end piston and hot junction piston are in the inner end of its respective stroke, at magnetic cold core driving coil group
In non-power status；
The check valve of process step one, cold end piston rest, the end motion to outside its stroke of hot junction piston, air admission hole connection is opened
It opens and is passed through dielectric gas into cooling piston cylinder, while the energization of magnetic cold core driving coil makes magnetic cold core to the medium by magnetic cold core
Gas heat release；
Process step two, cold end piston rest, the end motion into its stroke of hot junction piston, the check valve of thermal exhaust hole connection
It opens, the dielectric gas to heat up by magnetic cold core heat release in step 1 in cylinder is discharged by thermal exhaust hole, and passes through outer blowpipe chamber
The horn mouth at top slows down to form the outer layer air mass of package solder joint；

Gas heat absorption；
Process step four, hot junction piston rest, cold end piston think end motion in its stroke, the check valve of cold exhaust hole connection
It opens, the dielectric gas to cool down because magnetic cold core absorbs heat in step 3 in cylinder is discharged by cold exhaust hole, and passes through interior blowpipe chamber
The convergence mouth at top accelerates to form the internal layer air-flow of impact workpiece solder joint.
In above-mentioned flow, because internal layer air-flow due to being in direct contact less and workpiece of outer layer air mass and workpiece be in direct contact compared with
More, to make workpiece integrally tend to cooling trend, offsetting the heating that cold welding itself is brought influences；Outer layer air mass makes full use of simultaneously
The dielectric gas of heating enhances gas shielded effect, does not cause to waste when using dielectric gas such as argon gas；It only needs to magnetic cold core
The current strength of driving coil makes control, so that it may with change magnetic cold core heat release, caloric receptivity, to by outer layer air mass with it is interior
The temperature change of layer air-flow controls workpiece temperature.
In above-mentioned steps one, the dielectric gas after being heated by magnetic cold core energization heat release has substantially been detached from magnetic cold core
Contact, thus in the case that using small volume cooling piston cylinder and cold welding power cycles it is longer, can only carry out brief energization,
Slow down its power process by inductive effect later, is maintained to step 3 without lasting energization, therefore the design can be direct
It connects into the welding current control circuit of cold welding machine, control circuit is not separately provided.
Preferably, to prevent magnetic cold core from pushing displacement to make by air-flow during piston action, the design should also include magnetic
Cold core trip bolt passes through cooling piston cylinder casing wall to be connect with magnetic cold core, and magnetic cold core is fixed on cold by magnetic cold core trip bolt
