The residual water treatment facilities of a kind of soldering turret
Technical field
The utility model is used for automobile making automated production field, particularly relates to the residual water treatment facilities of a kind of soldering turret.
Background technology
In automobile body-in-white welding process, generate heat due to the big current of welding during welding gun work, therefore the whole course of work needs constantly to lead to recirculated cooling water to soldering turret.When electrode cap changed by needs, although cut off water inlet road, water has stopped flowing, but has water to remain in inside welding gun.Tearing open before cap just must to the residual water process of the inside, otherwise the moment that the residual water of the inside will be dismantled at electrode cap is spouting.Water flows out and production environment is deteriorated, and equipment around more gets rusty easily and service life shortens, and has electricity consumption potential safety hazard.
Analyze existing water treatment mode on the market, mainly containing two kinds: one is before electrode cap changed by needs, cuts off water inlet, and leads to gases at high pressure on water inlet road, is all blown out from water return outlet by the residual water inside water route by high pressure gas; Another kind is before electrode cap changed by needs, cuts off water inlet, produces negative pressure simultaneously, residual water is remained on inside welding gun on backwater road.The former through the air blowing of long period, by residual water process all for the inside totally, need could have a strong impact on productive temp, reduces production capacity.In addition, the high pressure gas blown into can enter the cooling water recirculation system of factory, if when exhaust has some setbacks, may there be a large amount of bubbles in water route, causes flowing water to be interrupted, thus affects the cooling of welding gun and then affect welding quality.Although the latter makes moderate progress, change electrode cap process water route and cut off, the production not meeting present main engine plants main flow is arranged, and also has potential safety hazard.
Even a lot of factories welding gun does not have residual water treatment when changing electrode, directly allows water spray, collects, be easy to a soldering turret surrounding environment and do very wet with a bucket.So not only easily cause the equipment of surrounding to get rusty because of contact water, and production environment is become very poor.
Based on above defect, the utility model is intended to solve changes the splashing of electrode cap residual water, the residual water better in process welding gun, and keeps circulation waterway continuous in whole replacing electrode cap process, reduction potential safety hazard.
