Description
Technical field
The utility model relates to a kind of vacuum pump sealed cover, particularly relates to a kind of vehicle-mounted vacuum pump sealed cover.
Background technique
Diesel engine and gasoline direct injection engine need be installed vacuum pump and provide vacuum source, meet vacuum boosting braking system requirement.In automobile engine system, vacuum pump is the cavity that a diameter is larger, and inside has a middle part that the diaphragm of push rod (or piston) is housed, and cavity is divided into two parts, a part communicates with air, and another part is connected with engine air inlet tube by pipeline.It sucks this principle of air when utilizing engine operation, causes the side vacuum of pump, relative to the pressure difference of opposite side normal air pressure, utilize this pressure difference to strengthen retrothrust.Fitted tightly by special fastening piece between vacuum seal cover plate and booster, form airtight cavity.Require very high to vacuum pump inside tightness in the process producing pressure difference, and tightness need to be ensured by the sealed cover of excellent planar degree to a great extent.Sealed cover itself needs special profile to agree with vacuum pump in addition, and therefore boundary dimension required precision is very high.
It is jagged that current vacuum pump cover plate stamps out blank surface band, must reach impulse-free robustness requirement required for vacuum pump cover plate by deburring operation, now adopts vibrations polishing or shot blast more.The shortcoming of existing technique is apparent: vibrations polishing time is long, and useful load is little.Environmental pollution is large, especially noise pollution, and product has the risk of mutually colliding with and wounding in addition; Shot blasting equipment has high input, and environmental pollution is large, and especially minute dusts pollutes.
Therefore, those skilled in the art is devoted to exploitation vehicle-mounted vacuum pump sealed cover new process and new product.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of vehicle-mounted vacuum pump novel seal cover plate.
For achieving the above object, cover plate of the present utility model is only completed by punching press on raw-material basis, the same with general stamping part in the fabrication process, there is collapse edged surface and burr face, but with beading feature in impact briquetting, do not need extra deburring operation, final product does not have burr and with beading.Concrete technological scheme of the present utility model is as follows:
A kind of vehicle-mounted vacuum pump sealed cover, comprise two sides, towards the outer side surface of the inner side surface of vacuum pump cavity and reverse vacuum pump cavity when being mounted on vacuum pump respectively, sealed cover thickness is 1 ~ 5mm, inner side surface is parallel with outer side surface, the planeness of inner side surface is less than 0.05mm, and outer side surface edge is with beading.
Preferably, the width of beading is 0 ~ 0.15mm, and the degree of depth of beading is 0 ~ 1mm.
Preferably, the mark of outer side surface in sealed cover is provided with and distinguishes, mark is located on outer side surface.Be designated one of the letter, numeral, symbol or any combination that stamp out.
Preferably, sealed cover has chamfering near the edge of outer side surface, and chamfering extends from the inside side of the outward edge of beading, and chamfer surface is plane or cambered surface.
The beneficial effects of the utility model are: remove punching burr by the external appearance characteristic changing product with more efficient, product plane degree is high, steady quality, and operation simplifies, and has obvious economic benefit.Beading feature is completed by special embossing die punching press, and product appearance is regular.In the process that beading is formed, the orthopaedic component of mould inside can synchronous working, the planeness optimization of product is improved, guarantees good quality of product.Therefore, beading feature effectively can meet the requirement of quality of product and manufacturing efficiency two aspect.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Accompanying drawing explanation
Fig. 1 is the sealed cover schematic shapes of the utility model preferred embodiment;
Fig. 2 is the sealed cover blank schematic cross-section of the utility model preferred embodiment;
Fig. 3 is the sealed cover finished product schematic cross-section of the utility model preferred embodiment.
Embodiment
The technological means realized to make the utility model, creation characteristic, reach function be easy to understand understand, below in conjunction with concrete schematic diagram, set forth the utility model further.
Can sealed cover be one of whole vehicle-mounted vacuum pump critical component that run well.When its planeness can not can badly influence sealing effect with Ontology Matching.Prior art adopts punching production sealed cover, then carries out deburring and polishing, wastes time and energy.
The utility model adopts explained hereafter unlike the prior art to go out the sealed cover of special shape.Fig. 1 is the schematic shapes of the present embodiment sealed cover.Sealed cover thickness is 1 ~ 5mm, and inner side surface is parallel with outer side surface, and the planeness of inner side surface is less than 0.05mm, and outer side surface edge is with beading.Towards the face of vacuum pump cavity when inner side surface refers to and is arranged on vacuum pump.The reverse vacuum pump cavity of another side of sealed cover, is called outer side surface.
Produce this sealed cover, first from raw material upper punch pressure cover plate blank, Fig. 2 is the edge cross-section schematic diagram of this kind of cover plate blank, and during punching press, face that is direct and punch. contact is the inner side surface 2 of cover plate, and another side is the outer side surface 1 of cover plate.The outer side surface band jagged 3 of cover plate blank, outer side surface edge stands the pressure vertical with inner side surface, and the while that burr 3 being removed, edge sink, and forms beading 4, as shown in Figure 3.The width of beading 4 is 0 ~ 0.15mm, and the degree of depth of beading 4 is 0 ~ 1mm.Sealed cover edge also can simultaneously by the pressure almost parallel with interior outer side surface, and make to have chamfering 5 near sealed cover outer side surface 1 periphery like this, chamfering 5 extends from the inside side 2 of the outward edge of beading 4.Chamfer surface is plane or cambered surface.
In order to distinguish inner side surface and outer side surface better, the mark of outer side surface in sealed cover is provided with and distinguishes, mark is located on outer side surface.Be designated one of the letter, numeral, symbol or above-mentioned combination in any that stamp out.
The present embodiment adopts special process to produce sealed cover, provides a kind of sealed cover had with beading.In beading forming process, the burr produced during punching press is eliminated, and due to the shaping feature in mould, the planeness of part can suboptimization again.Beading feature effectively can meet the requirement of quality of product and manufacturing efficiency two aspect.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
