When machine adopts wetly when cutting processing technology, owing to have water smoke in the module that connects material in the process, to splash everywhere for preventing these water smokes, the module that connects material plays the function that waterproof is splashed.Add man-hour wet cutting, the sweep-up pipe installing hole of the module afterbody that connects material is blocked with plug, prevent that water smoke is emitted to working space.
Add the sewage water filtration recycling module that water circulation in man-hour module comprises that water distributor and processing back produce wet cutting.Wherein water distributor is to import to cut point to the cooling water of high pressure, and water jet is full of the internal diameter of whole tubing, and sewage water filtration recycling module is the sewage collecting that produces in the process, filters through filter.
Whole water cycle process is: water distributor imports to cut point to clean high-pressure cooling water; The sewage that produces in the process collects through each collector pipe; Be pooled to sewage filter device and filter, be transported to cut point through water distributor again after pressurizeing through water pump through the clean water that removes solid residue and greasy dirt in the decontaminated water behind the multistage filtering.Thereby the realization water circulation use reduces the sewage discharge in the process, energy-conserving and environment-protective.
In the cut, the cooling water effect of importing: 1. when cut, cool off tubing.2. removing chip.Motlten metal and metallic vapour are in the deposition of tube surfaces, and the cooling water of importing can produce the very thin moisture film of one deck at surface of the work, drop on the surface that the particle on the film cools off and can't be bonded in workpiece very soon.The auxiliary gases at high pressure coaxial with laser beam blow out cutting area to the chip of cooling, and chip is pooled to sewage filter device together in company with current and filters.Centrifugal pump in the utility model pressurizes to cooling water, can play the effect of removing chip better.
The water distributor of laser cutting machine, the process introducing water under high pressure that is used for Laser Processing microtubules diameter pipes cools off fast, prevents the excessive calcination of tubing, reduces the pollution in the cutting process.Used water supply installation, it is unstable to have overcome the existing water system water supply of water supply, and structure is not compact, and entire equipment takes up space greatly, the drawback that equipment cost is high, having supplies water stablizes, compact conformation, entire equipment takes up space little, the advantage that equipment cost is low.
The utility model proposes is applicable to the miniature tubing Laser Processing of thin-walled; Can simultaneously compatible driedly cut and wet and cut the device of two kinds of processing technologys; And between two kinds of processing technologys, switch simple and conveniently, do not need other equipment and device, moreover cooling water can recycle; Practice thrift production cost, obtained better technical effect.
