Abstract
The invention discloses a method for pressing inner skins of front pillars. The method is implemented through the steps of drawing the shape of a product in place by one step with a drawing die, then, carrying out punching and edge cutting and trimming on the product by using an edge cutting die and a cutting-off die, so that processing on the shape and all holes and edges of the product can be completed just through three steps. Therefore, the method disclosed by the invention solves the problems in the prior art, improves the utilization ratio of materials, shortens the procedures, and reduces the times of product rotating and clamping and the number of production equipment; and multiple procedures are completed through one time clamping operation, thereby simplifying the processing step, improving the processing efficiency, reducing the manpower cost, and guaranteeing the product quality and the product stability.
Description
Technical field
The present invention relates to minicar member process technology, particularly a kind of method for pressing inner skins of front pillars of minicar.
Background technology
It is A00 level car in the A type car that minicar refers generally to, and this axletree is apart from generally between 2 meters to 2.2 meters (the part vehicle is outside this scope), and engine displacement is generally less than 1 liter.
Front pillar of mini car refers to that minicar driver's cabin the place ahead supports the support member of cab ceiling, and this support member is by support column and be fixed on the inside panel of support column inboard and several parts of exterior skin in the outside consist of.
Existing a kind of front column inner skin of miniature vehicle member, its structure 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 in detail member being described in detail, the actual installation state is direction reference when using with product members, refer to 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, flange the first half also has the forward journal stirrup 2 of projection, posterior edges has the flanging 3 that folding rear cross section is " z " font, its inside is disposed with a line hole 4 from top to bottom, a spraying coating process circular hole 5 that is used for spraying, two are used for fixedly 6, two blocked holes 7 that are used for fixing self of circular hole of fixing handle of shaking hands; On the flanging of posterior edges, also have two welding locating holes 9.
Existing front column inner skin of miniature vehicle 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 the modes such as vertical trimming and rotation angles of product vertical trimming, adds and need to adopt multiple clamping man-hour and change positioning datum.So just increase technological requirement, prolonged the production cycle, increased positioning difficulty, so just limited class's output of product.Also need simultaneously multiple clamping, cause positioning datum inconsistent and increased percent defective, be difficult to guarantee batch production.
Therefore there are the defectives such as processing step is complicated, the production cycle is long, and qualification rate is low in existing inner skin processing method of front pillar of mini car.
