Abstract
The present invention relates to automotive floor panel part production technology field, the manufacturing process of a kind of automobile front floor secondary drawing；It includes drawing top die, a drawing lower punch and the first blank holder being located on a drawing lower punch；Secondary drawing top die, secondary drawing lower punch and the second blank holder being located on secondary drawing lower punch；It is characterized in that: one time drawing top die correspondence treats that the highest point of drawing part is provided with capaciting material groove.The present invention uses above-mentioned design, reserves processing leeway, and develops secondary drawing mould, carry out secondary drawing in a drawing, solves drawing and moulding mould of tradition, the problem that large scale, deep-drawing are existed part cracking.
Description
Technical field
The present invention relates to automotive floor panel part production technology field, the manufacturing process of a kind of automobile front floor secondary drawing.
Background technology
At present, there is cracking risk and cannot effectively optimize in automotive floor panel part in a drawing die, the problem that there is easily cracking at the especially sharp-pointed fillet of large-scale deep-drawing part.
Summary of the invention
It is an object of the invention to, it is provided that a kind of secondary drawing technique for large-scale deep-draw plates such as large-scale deep-drawing punching parts especially automobile front floors, to overcome the problem that there is easily cracking at the especially sharp-pointed fillet of large-scale deep-drawing part.
In order to achieve the above object, the present invention is achieved in that
A kind of die assembly for automobile front floor secondary drawing, it includes drawing top die, a drawing lower punch and the first blank holder being located on a drawing lower punch；Secondary drawing top die, secondary drawing lower punch and the second blank holder being located on secondary drawing lower punch；It is characterized in that: one time drawing top die correspondence treats that the highest point of drawing part is provided with capaciting material groove.
A kind of secondary drawing method for manufacturing automobile front floor；It is characterized in that: it includes:
Step one, use cae analysis software analysis parts modeling to be punched, the highest point after a drawing top die correspondence forming parts arranges capaciting material groove；
Step 2, with drawing top die, a drawing lower punch and the first blank holder of being located on a drawing lower punch material carried out drawing operation for the first time；
Whether step 3, post-job material of drawing of inspection form reserved clout heap；
Step 4, with secondary drawing top die, secondary drawing lower punch and the second blank holder of being located on secondary drawing lower punch material carried out second time drawing operation.
The present invention uses above-mentioned design, reserves processing leeway, and develops secondary drawing mould, carry out secondary drawing in a drawing, solves drawing and moulding mould of tradition, the problem that large scale, deep-drawing are existed part cracking.
Accompanying drawing explanation
Fig. 1 is the structural representation of top die of the present invention.
Fig. 2 is the structural representation of secondary top of the present invention die.
Detailed description of the invention
The present invention is further illustrated below by way of specific embodiment.
As shown in Figure 1 and Figure 2, a kind of die assembly for automobile front floor secondary drawing, it includes 1, drawing lower punch of a drawing top die and the first blank holder being located on a drawing lower punch；Secondary drawing top die 2, secondary drawing lower punch and the second blank holder being located on secondary drawing lower punch；It is characterized in that: one time drawing top die 1 correspondence treats that the highest point of drawing part is provided with capaciting material groove 3.
A kind of secondary drawing method for manufacturing automobile front floor；It is characterized in that: it includes:
Step one, use cae analysis software analysis parts modeling to be punched, the highest point after a drawing top die correspondence forming parts arranges capaciting material groove；
Step 2, with drawing top die, a drawing lower punch and the first blank holder of being located on a drawing lower punch material carried out drawing operation for the first time；
Whether step 3, post-job material of drawing of inspection form reserved clout heap；
Step 4, with secondary drawing top die, secondary drawing lower punch and the second blank holder of being located on secondary drawing lower punch material carried out second time drawing operation.
The present invention uses above-mentioned design, reserves processing leeway, and develops secondary drawing mould, carry out secondary drawing in a drawing, solves drawing and moulding mould of tradition, the problem that large scale, deep-drawing are existed part cracking.
