In machine and making a process of metallic spare parts, spend to the cleanness of the spare parts have very high demand, because this is right,the spare parts undertakes storing, treatment and constructional fundamental condition. Now, a variety of cleaning means can satisfy pair of cleanness to spend the diversification demand with quality, this are made in the car, aviation project, electron and auxiliary material supply the expression in waiting for essential industry to must be highlighted particularly. The impurity of the generation in production process and pollution can affect the quality of the spare parts, function and service life, increase manufacturing cost and percent defective thereby. Because manufacturing part is more and more cabinet, more and more complex, this makes the spare parts cleans the job to make the important segment in product quality catenary. Now, a variety of cleaning means can satisfy pair of cleanness to spend the diversification demand with quality. Cleaning the main method that at present industrial spare parts cleans the method is so called " wet and chemical craft " , although use liquid medium,undertake cleaning. Clean the effect to rise, use toward contact a few additional physical method. Now, choose medium of ability in swimming or solvent medium, use innovation, clean a system custom-builtly for the user, can have satisfied the requirement that all sorts of industry spare partses clean. To choose the method that clean correctly, general need considers the following factor: The type of contaminant and degree; The material of the spare parts is qualitative; The geometrical appearance of the spare parts; To the requirement of finishing quality and used pretreatment technology; Produce cycle and yield; The cleanness that needs to achieve spends grade and follow-up working procedure to be opposite the requirement that cleans a spare parts. The choice cleans craft and medium suitably to be in wet and chemical craft, the effect that clean basically depends on the solvency that cleans medium. What often use at present is Shui Jiqing lotion and dissolvent. The efficiency that clean is main also be decided by cleans medium suitably at whether choosing, experience makes clear, choose to clean medium to will affect the stability of final quality, cost and craft badly erroneously. Water radical cleans an agent most agree with the spare parts that cleans emulsion pollution. Gush drenchs clean the large part that basically is used at cleaning to have bigger even face, also can use at directional clean, if clean a certain hole only. The spare parts of appearance of intricate to having geometry, be like blind aperture or groove, basically use immersion craft to clean, to improve the result that clean, the spare parts often undertakes in clear washing trough whirly or whirligig. High-pressured shedding is cleaned, also say efflux is cleaned, combine application with immersion craft normally, special apply to clean blind aperture and screw (graph 1) . The EcoCFlex of company of Rr Ecoclean of ü of graph 1 D cleans a system to be able to finish a variety of cleaning craft. Of forehead among it is efflux clear washing trough, can see high-pressured unit should be cleaned from the back by abrade cream or polishing creams when contaminative spare parts, or when the spare parts that cleans aperture having blind and intricate geometry appearance, to the requirement that clean will be highest, can use ultrasonic to clean craft to help right now undertake machinery is cleaned, especially the impurity of stickiness. What vapour degreasing basically applies to surface of purify spare parts is smeary with grease, stem from environment and the reason that health protects, use steam defatted craft should preferential the plan that chooses closed circuit equipment, can reduce solvent vapour so to all round atmospheric is discharged. Use dry-clean (blowy) the law is OK low cost ground undertakes handling to the spare parts, this kind of method often is used at purify fragment impurity or dry spare parts. Except afore-mentioned clean craft beyond, still have a few special work skill purify the pollution of special kind, satisfy special requirement. For example: CO2 gush snow is cleaned, can well of shape of film of surface of purify spare parts or the impurity of solid state, do not have remain almost. Craft of dry ice eject uses glacial pill and not be liquid state CO2 serves as clean medium. Clean in plasma in, use different reaction gas to come purify the layer of organic contaminant. Carbolic hydrogen cleans systematic environmental protection the carbolic hydrogen that Rr Ecoclean of ü of efficient Germany D makes cleans a system to have very tall production efficiency already special environmental protection, the production of OK and contented user asks. The Luo Lan production company of city of Zhu Sai of American horse Sa devotes oneself to axial circle and tigidity / flexible axial production, use a variety of data (carbolic steel, stainless steel or aluminium) produce a variety of size (10 ～ 178mm) high accuracy spare parts. These spare partses, contain the part of carbolic steel material of black oxide especially, right clean spent demand is very high. Pass long-term comparison, luo Lan chose the carbolic hydrogen that makes by Rr Ecoclean of German D ü to clean a system. This system includes immersion type to clean, efflux is ejective clean and vacuum evaporates go grease, this process is OK will discharge fall almost for 0. Subsequently, luo Lan company installed the small-sized 80C spare parts of company of D ü Rr to clean a system. Equipment grows only 3. 5m, wide 1.
3m, operation personnel needs to put the part only clean basket, the machine expects with respect to can automatic fluctuation, the spare parts can be being cleaned the room is automatic clean. Luo Lan uses over all dimension to clean basket for provide for oneself of 180mm of × of 230mm × 480mm, every clean basket to be able to install 200 ～ probably 250 axle sleeve or axis, or 3000 smaller parts. Normal circumstance falls to be able to clean 60 basket everyday. The metre of this kind of new cleaning machine is 7min, need only former the time of the half, one times faster than cleaning a method traditionally. Although craft asks pair of product quality are very captious, but even so, this system still can spare parts surface even the oil of blind Kong Zhong is cleaned clean. The industrial hardware rinsing equipment on rinsing equipment market and system divide configuration of single accent and much speech type, can serve as clean a line continuously. All equipment can combine application with the robot. If equipment of single accent system is deployed a few additional clean a function, be cleaned like ultrasonic or high-pressured shedding is cleaned, the machinery that can realize place to need better cleans the effect. Same, in close dry program also can be set in working antrum, if vacuum is dry. A of much antrum system prominent dominant position is Gao Tun says ability, because be in different clear washing trough,can clean a few batches of spare partses at the same time (graph 2) . Company of Rr Ecoclean of ü of graph 2 D is produced from small-sized sheet antrum rinsing equipment goes to what much antrum cleans a system all sorts of device, be an user any cleaning the problem offers system of corresponding solution belt conveyer to apply in gush to drench normally in filter cloth cleaning device, its structure should suit treat the geometrical external form that cleans a spare parts. The pace is entered continuous carrying a system is a kind of solution that can achieve Yan Ke to clean the task, normally application is cleaned at high-pressured shedding as directional as high pressure in cleaning the technology that combines. In production of big batch car, often use this kind of plan to clean the component of engine and transmission system. Clean the task to be finished better, often choose a robot. Below most circumstance, be called " the robot is unit " device is being cleaned through manipulator the spare parts conveys in the process. The robot also can deserve to have nozzle, spray gun or other tool (if be used at purify burr) , clean the job specificly in order to finish. Reduce the loss of medium to reduce power comsumption as far as possible, advanced wet and chemical clean a system to often use closed circuit design, make clean medium to pass inside system of buy type distill is used circularly. Through choosing technology program and the component configuration that choose high quality seriously, can be below the premise that accords with safe, health and environmental protection standard, make sure first-rate cleans quality, raise utilization rate of equipment and installations and reduce cost. Can optimize cost structure so, avoid the generation of reject, increase the competitive capacity of the enterprise. CNC Milling
