A kind of common and conllinear panoramic skylight top cover manufacturing process
The invention belongs to the technical fields of automobile industry Cold Press Working, and in particular to a kind of common skylight and panoramic skylight
Top cover sharing die, and the mode of mixed production.
Top cover outside plate is as vehicle exterior cladding element, and Forming Quality directly affects vehicle presentation quality, assembling quality, with people
Increase to configuration of automobiles diversified demand need to produce common skylight and panoramic skylight top cover simultaneously with a vehicle.
Fig. 1 is common skylight version top cover part drawing, this top cover is three-box car form, and front and rear portions moulding is relatively easy, but day
Window area shape is more complex, and conventional molding process needs four procedures to complete.
Fig. 2 is common skylight version top cover, and the detailed enlarged drawing in skylight opening region, in Fig. 2,2.1 be skylight epistome, and there are negative
Angle indent moulding, 2.2 be skylight opening left and right sides position, turns over whole face there are inside negative angle, 2.3 for after skylight opening along position, inwardly
There is negative angle and turn over whole moulding in flange moulding, skylight opening border, moulding process is that drawing → deburring → flange → rollover is whole.
It at four peripheral angle of top cover outside plate, since fillet is small, can not be settled at one go by drawing, need to do drawing processing,
Thus the full process complete scheme of traditional handicraft, as shown in figure 3, being drawing → skylight opening deburring surrounding shaping → straight flange of skylight opening
Surrounding deburring → whole the punching of skylight opening rollover.
Fig. 4 be panoramic skylight version top cover part drawing, 4.1 be the moulding of skylight opening region, relative to common skylight version top cover compared with
Simply, there is no negative angles to turn over whole moulding, and traditional handicraft can be completed by three sequences, and process program is illustrated in figure 5 drawing → skylight
The mouth deburring surrounding shaping → straight flange punching of skylight opening.
Traditionally scheme, common skylight and panoramic skylight top cover need 7 molds, mould development, maintenance cost altogether
Height, and due to two kinds of independent mold developings of skylight top cover, when production, individually can only more be changed the mold according to two kind products
Tool production, increases mold conversion time, and the production capacity for influencing automatic production line is promoted.At high cost, low efficiency, influences product competition
Summary of the invention
The prior art, because of no skylight top cover, is not related to skylight area for having skylight and can accomplish to share without skylight top cover
Domain bonding relation, the compensation of the face A are actually not required to consider compensation rate inconsistence problems to have based on skylight board top cover.
Panoramic skylight and common skylight drawing, which share, need to solve the compensation of the face A and skylight matching problem, due to the A of two kinds of products
Face skylight springback compensation, center of gravity, matching relationship are entirely different, by carrying out a large amount of simulations point to matching relationship and parts quality
Analysis increases priority control line, and big scuttle rebound compensation amount is found out in sunykatuib analysis, final to realize that drawing die shares.
A kind of common and conllinear panoramic skylight top cover manufacturing process, which is:
Common skylight and panoramic skylight top cover sharing die, and mixed production；
First step: louver portion, which uses to repair, turns over integration mold design structure, realizes that one sequence of deburring shaping forms, but by
The problems such as to turn over insert intensity poor in repairing, while also needing to overcome flange lateral force, Yi Lamao.In order to solve the above problem, take with
(1) product optimization: increasing insert intensity, guarantees that punch-die insert thickness is not less than 8mm by product optimization.
(2) promote mold material: quenching technical improves and increases mold spare part, and quenching technical is Cr12MoV integral quenching.
Cr12MoV integral quenching is optimized for by former as cast condition 7CrSiMnMoV surface hardening.
(3) flange punch-die is mutually tossed about with deburring cavity plate, eliminates internal stress.
The second step: common skylight top cover: modifying skylight opening region, and when panoramic skylight only carries out surrounding whole
Shape, skylight opening region carry out mechanism switching (this switching belongs to the prior art), are equivalent to production without skylight board top cover.
The third step: common skylight top cover: turn over to skylight opening region whole, molds final products shape, this process
Panoramic skylight top cover is without action.
The fourth step: panoramic skylight top cover: repair turning over, molds final products to skylight opening region, the common day of this sequence
Window top cover is not required to action.
As shown in fig. 6, drawing → repair that window of overturning the heavens → surrounding shaping → skylight opening turns on one's side whole punching or skylight opening is repaired and turns over punching
Sharing of die when drawing repairs window of overturning the heavens and is only used for common skylight, is switched to no skylight when producing panoramic skylight, and four
Sharing of die when all shapings, turn on one's side whole punching of skylight opening are only used for common skylight, and skylight opening, which is repaired, to be turned over punching and be only used for panoramic skylight；
Above scheme realizes mold and is reduced to 4 sequences, but when the different top covers of production, there is still a need for output to cut for third sequence mold
Common skylight top cover third sequence is mounted on third platform press, and panoramic skylight third sequence is mounted on the 4th press, raw
When producing common skylight, the 4th press is set as motionless, and head part sucker rises, and is equivalent to idle station bracket, produces panoramic skylight
When, third platform press is set as motionless, is equivalent to idle station.
It when the outside grip of the 4th press, while needing to grab big skylight opening waste material to production line line tail, 10 is arranged altogether
Sucker, as shown in fig. 7, the first sucker 7.1 therein and the second sucker 7.2, when producing common skylight, no product is adsorbable,
In gas leakage state, product can not be picked up, for this purpose, increase throttle valve in the gas circuit of the first sucker 7.1 and the second sucker 7.2,
The first sucker 7.1 and the second sucker 7.2 are locked when producing common skylight version top cover.
Beneficial effects of the present invention:
Common skylight and panoramic skylight top cover sharing die, and mixed production；Mold is reduced to 4 sequences, mould development, dimension
Protect it is at low cost, and due to two kinds of skylight top cover molds share, shorten mold conversion time, improve automatic production line
