Description

A kind of minicar front column inside panel processing knife edge die
Technical field
The present invention relates to minicar member process technology, particularly a kind of minicar front column inside panel processing knife edge die.
 
Background technology
It is the A00 level car in the A type car that minicar refers generally to, and this axletree distance is between 2 meters to 2.2 meters (the part vehicle is outside this scope) generally, and engine displacement is generally less than 1 liter.
The minicar front column is meant that minicar driver's cabin the place ahead supports the support member of driver's cabin ceiling, and this support member is made up of the support column inside panel inboard with being fixed on support column and several parts of exterior skin in the outside.
Existing a kind of minicar front column inside panel member, its structure is as shown in Figure 1, for the slightly recurvate integral body in two ends is tabular strip (when relating to the narration of direction when in this specification member being detailed; The actual installation state is direction reference when using with product members; Be meant that such as the forward edge of member the member actual installation is positioned at the edge position of the place ahead one side after good), its forward edge has the flange 1 of outside turnover, and flange the first half also has protruding forward journal stirrup 2; Posterior edges has the flanging 3 that cross section, folding back is " z " font; Its inside is disposed with fixedly circular hole 6 of handle that 5, two of spraying coating process circular holes that 4, one in a line hole is used to spray are used for fixing handle from top to bottom; Two blocked holes 7 that are used for fixing self, and a square hole 8 that is used for fixing inside gadget; On the flanging of posterior edges, also have two welding locating holes 9.
Existing minicar front column inside panel generally adopts the plate of irony, obtains through drawing just behind the one-step forming through Punching Technology repeatedly again.It adds man-hour, needs to adopt modes such as vertical trimming and rotation product angle vertical trimming, adds and need adopt multiple clamping man-hour and change positioning reference.So just increase technological requirement, prolonged the production cycle, increased positioning difficulty, so just limited class's output of product.Also need multiple clamping simultaneously, cause positioning reference inconsistent and increased percent defective, be difficult to guarantee to produce in batches.
So there are defectives such as processing step is complicated, the production cycle is long, and qualification rate is low in existing minicar front column inside panel process technology.
 
Summary of the invention
Deficiency to above-mentioned prior art; The technical problem that the present invention will solve is: how a kind of minicar front column inside panel processing knife edge die is provided, and this knife edge die one-step punching can process many places planform on the inside panel, improves working (machining) efficiency; Simultaneously can realize a kind of minicar front column inside panel processing method based on this knife edge die; This method has been simplified processing step, has improved working (machining) efficiency, has improved the product passing rate of processing simultaneously.
In order to solve the problems of the technologies described above, adopted following technical scheme among the present invention:
A kind of minicar front column inside panel processing knife edge die; Comprise counterdie and patrix; The periphery of said counterdie is provided with several guide pillars that is used to lead straight up; The guide pillar lower end also is arranged with and is used for patrix spacing limited block when descending; The counterdie upper surface middle part is provided with down the cutter piece, and the following cutter piece outer surface type shape and the second semi-finished product inner surface of component match, and the position at the middle part of part and two ends has and is used for die-cut cavity between corresponding two members of following cutter piece upper surface; The position of following cutter piece upper surface counterpart member spraying coating process circular hole is provided with spraying coating process circular hole blanking groove, and the position that following cutter piece upper surface counterpart member is positioned at second blocked hole of below is provided with second die-cut blanking groove of blocked hole; The middle part in the dual-side portion of said counterdie upper surface corresponding two members outside and the position at two ends also are respectively arranged with the drive block that upper surface is the smooth plane that slopes inwardly; The periphery of said patrix lower surface is provided with the guide pin bushing that is used for cooperating with guide pillar guiding; Middle part, said patrix lower end is provided with eccentric swage; The eccentric swage lower surface type shape and the second semi-finished product inner surface of component match; The eccentric swage upper end is connected with patrix elasticity; The patrix lower end also has the upper slitter piece that is provided with straight down; Said upper slitter piece comprises that being used for correspondence cuts away the first upper slitter piece of the unnecessary blank of upper end position between two members, is used for the 3rd upper slitter piece that correspondence is cut away the second upper slitter piece of the unnecessary blank of medium position between two members and is used to cut away the unnecessary blank of lower end position between two members; The said first upper slitter piece, the second upper slitter piece and the 3rd upper slitter piece all run through the eccentric swage setting slidably; Also vertically run through slidably in the eccentric swage of said patrix lower end and be provided with spraying coating process circular hole drift; Said spraying coating process circular hole drift on the following cutter piece the blanking groove setting of spraying coating process circular hole and be used to punch out member spraying coating process circular hole, also vertically run through being provided with second blocked hole drift in the eccentric swage of said patrix lower end slidably, said second blocked hole drift on the cutter piece down the die-cut blanking groove setting of second blocked hole and be used to punch out second blocked hole of member lower end; The middle part in corresponding two members outside, said patrix below and six positions at two ends also are respectively arranged with the side cutting mechanism; Said side cutting mechanism comprises that a upper end is fixed on the patrix, and what the lower end had a low slid plane, inboard high outside hangs the contract take-up housing, hangs slidably on the said slid plane of hanging the contract take-up housing and is connected to a side cutting knife piece; Side cutting knife piece lower outside have be used for counterdie on the face that is slidingly matched that is slidingly fitted of drive block upper end clinoplain, inboard, side cutting knife piece lower end has the cutter head that partly is provided with over against the member respective outer.
