Description
Technical field
The utility model belongs to rubber seal punching techniques field, more specifically to a kind of four holes of filter
Sealing ring punching tool.
Background technique
Filter is the important component for automobile filtering system, primarily serves the effect of impurity screening or gas, than
More typical automobile filter has: air cleaner, air-conditioning filter cleaner, oil filter and fuel filter, every kind of filter
The impurity of corresponding filtering all difference, but it was substantially the impurity of air filtering or class of liquids.Filter is in engine
It is primarily served in system and filters out objectionable impurities, reduce the abrasion of engine components, extend the effect of these component service lifes, filtered
The structure of each component will influence whether the service performance of filter in clear device.
Wherein, oil filter is located in engine lubrication system, its upstream is lubricating oil pump, and downstream is needed in engine
Each components to be lubricated.With moving components such as pistons in automobile engine, these machines are reduced using engine lubricating oil
The frictional resistance of tool component, with anti-wear, to keep engine motor oil cleaning protection engine, oil filter is played to Guan Chong
It acts on.Engine part can be worn in operation generates metal fillings grain, when supplementing machine oil, can also enter tiny dirt from oil filler
Sand, the abrasion of the parts such as these metal fillings grains and dirt sand meeting acceleration motor inside crankshaft, bearing, cylinder sleeve and piston, in addition, machine oil
Because chemical change generates clay shape organic matter under engine operation process high temperature state, these clay shape organic matters can be clung
Moving parts increase resistance, are effective protection engine, it is necessary to filter out these mechanical admixtures and greasy filth by oil filter.
Fuel filter is the work of fuel filter on the pipeline being connected between fuel pump and throttle valve body oil inlet
With mainly filtering the iron oxide that is contained in fuel oil, the structure of fuel filter is that have stainless steel in an aluminum hull and one
Bracket composition, forms on bracket equipped with the high-efficient filter scraps of paper, filter paper is at cosmos, to increase circulation area.And sealing ring is
Important composition component in above-mentioned all kinds of filters, the sealing ring of the utility model are the weights for controlling oil stream amount in filter
The rubber accessory wanted, main function oil will be flowed into filter by four holes of sealing ring side, to guarantee in filter
Oil mass, therefore just on sealing ring hole size require it is relatively high.
Due to being influenced by sealing ring special construction, can not be incited somebody to action during sealing ring sulfidization molding in currently available technology
Above-mentioned hole directly processes, and otherwise will cause the sealing ring after vulcanizing can not be demoulded.It is in the prior art usually close
The hole (semicircle orifice) of half is first processed during seal sulfidization molding, is opened again by means of auxiliary mould after then demoulding
Hole.At present in industry, the country can efficiently produce above-mentioned sealing ring, but compare shortcoming in punching this part, and foreign countries are logical
It crosses more advanced equipment to be punched out, cost is relatively high, and domestic mainly by manually carrying out rushing for a Kong Yikong, punching
Inefficiency, qualification rate it is relatively low, often punching is inclined.
Therefore, the punching efficiency and punching precision of above-mentioned filter sealing ring are improved, reduction rejection rate just has important
Meaning.
