Description
Technical field
The present invention relates to technical field of automobile parts, relate in particular to that a kind of auto parts and components useThe manufacture method of rubber wick.
Background technology
Along with the development of China's automobile industry grows, at the beginning of domestic automobile manufactures in 20112,000 ten thousand of step statistics, account for No. 1 in the world. For meeting the market requirement, meet its people'sDesire to purchase and requirement, Ge great main engine plants are numerous and confused releases fashionable, safety and comfort, price is suitableIn, the new model of environmental protection and energy saving, Ge great main engine plants are more and more higher to supplier's requirement simultaneously,Selection has availability, constant product quality, and technology and equipment advanced person, the supply of material is timely,Serve, how the low matching system of including in of price, tackle the annual 5%-15% of Ge great main engine plants notWith the price reduction index of degree, opportunity, pressure and challenge deposit concerning automobile component part supply business.Eliminate for the market not being growing more intense, meet the requirement of Ge great main engine plants, supplier is notDisconnected improve internal control, recruitment has the professional of professional knowledge and professional ability, and expansion is groundStudy carefully development teams, update backward technique and technology, eliminate and fall behind production equipment, makeError-proofing tool, training employee, improves employee's operation technical ability and quality mind, and internal economies digsDive, reduce production costs, enhance productivity, stabilized product quality, for development of automobile is madeContribute and occupy a tiny space. Automobile Design mainly contains four large classes, wherein in engine and chassisMany points of parts are rubber hose, in these point of part, it important work to rubber hoseWith. Engine has air-conditioning system and cooling system, the connection of air-conditioning system and cooling system aroundPosition is to be connected by rubber tube; The power steering system of chassis portion is unified brake system also by rubberPipe connects. Because these rubber product majorities belong to high-voltage product, its product structure design is commonAdopt the braider braiding that two-layer braiding and tension are large, traditional handicraft in the past generally adopts steelCore mold, as the core of sebific duct, can only adopt horizontal vulcanizer if adopt steel core to manufacture sebific ductSulfuration, and horizontal vulcanizer length is the longest namely 20 meters both at home and abroad, that is to say every glue20 meters of the effective lengths of pipe. Because hose manufacturing process flow process has determined that rubber wick is repeatedlyIn use procedure, will shorten gradually, its hose manufacturing process flow process is as follows: sizing material banburying--fuse--interior glue is extruded, and----outer glue is extruded, and--warehouse-in is checked in sulfuration--depoling--in braiding to manufacture preparation. Sebific duct systemMake and need just can complete through multiple working procedure, rubber wick will after the Reusability of multiple working procedureShorten gradually, if short rice rubber wick cannot be connected as one, increase fuse length,Short rice fuse can only be scrapped processing. The external diameter of rubber wick is the internal diameter of sebific duct namely, rubber coreSub-outside dimension directly affects the internal diameter size of sebific duct, and short rice fuse is extruded with outer glue and squeezed at interior glueWhile going out, size fluctuation is large, and size is difficult to control, and has indirectly affected the internal diameter size of sebific duct andFinished product quality, if fuse is short, fuse radical is more, sebific duct stub bar is more, wasteLarger, cost is higher, there is no competitiveness in the same industry.
