Abstract
The invention relates to the manufacturing process field of automobile floor components, in particular to a secondary drawing manufacturing process for a front automobile floor. A mold assembly comprises an upper concave mold for primary drawing, a lower convex mold for primary drawing, a first blank holder arranged on the lower convex mold for primary drawing, an upper concave mold for secondary drawing, a lower convex mold for secondary drawing, and a second blank holder arranged on the lower convex mold for secondary drawing, wherein the upper concave mold for primary drawing is provided with an accommodating tank corresponding to the highest places of the components to be drawn. The mold assembly adopts the design, and sets aside a processing room in the primary drawing; and the secondary drawing molds are developed for the secondary drawing to solve the rupture problem of the large-size and deep-drawing components in traditional once drawing molds.
Description
Technical field
The present invention relates to automotive floor panel part production technology field, be specially a kind of manufacturing process 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, and the especially sharp-pointed fillet of large-scale deep-drawing part place exists the easily problem of cracking.
Summary of the invention
The object of the invention is to, a kind of secondary drawing technique for large-scale deep-draw plates such as large-scale deep-drawing punching parts especially automobile front floor is provided, to overcome the especially sharp-pointed fillet of large-scale deep-drawing part place, have the problem of easy cracking.
In order to achieve the above object, the present invention is achieved in that
For a die assembly for automobile front floor secondary drawing, it comprises once draws with top die, once draws with bottom punch and be located at the first blank holder once drawing with on the punch of bottom; Top die for secondary drawing, secondary drawing is with bottom punch and be located at the second blank holder on the punch of bottom for secondary drawing; It is characterized in that: once draw with the highest point of top die correspondence part to be drawn and be provided with capaciting material groove.
A kind of secondary drawing method for the manufacture of automobile front floor; It is characterized in that: it comprises:
Step 1, use cae analysis software analysis parts modeling to be punched, arrange capaciting material groove at the highest point once drawing with after top die correspondence forming parts;
Step 2, use are once drawn with top die, are once drawn with bottom punch and be located at the first blank holder once drawing with on the punch of bottom material is drawn to operation for the first time;
Step 3, inspection are once drawn post-job material and whether are formed reserved clout heap;
Step 4, with top die, secondary drawing for secondary drawing with bottom punch be located at secondary drawing, with the second blank holder on the punch of bottom, material drawn to operation for the second time.
The present invention adopts above-mentioned design, reserves processing leeway, and develop secondary drawing mould in once drawing, and carries out secondary drawing, solves a drawing and moulding mould of tradition, large scale, deep-drawing is existed to the problem of part cracking.
Accompanying drawing explanation
Fig. 1 is the structural representation of a top die of the present invention.
Fig. 2 is the structural representation of secondary of the present invention top die.
The specific embodiment
By specific embodiment, further illustrate the present invention below.
As shown in Figure 1 and Figure 2, a kind of die assembly for automobile front floor secondary drawing, it comprises once draws with top die 1, once draws with bottom punch and be located at the first blank holder once drawing with on the punch of bottom; Top die 2 for secondary drawing, secondary drawing is with bottom punch and be located at the second blank holder on the punch of bottom for secondary drawing; It is characterized in that: once draw with the highest point of top die 1 correspondence part to be drawn and be provided with capaciting material groove 3.
A kind of secondary drawing method for the manufacture of automobile front floor; It is characterized in that: it comprises:
Step 1, use cae analysis software analysis parts modeling to be punched, arrange capaciting material groove at the highest point once drawing with after top die correspondence forming parts;
Step 2, use are once drawn with top die, are once drawn with bottom punch and be located at the first blank holder once drawing with on the punch of bottom material is drawn to operation for the first time;
Step 3, inspection are once drawn post-job material and whether are formed reserved clout heap;
Step 4, with top die, secondary drawing for secondary drawing with bottom punch be located at secondary drawing, with the second blank holder on the punch of bottom, material drawn to operation for the second time.
The present invention adopts above-mentioned design, reserves processing leeway, and develop secondary drawing mould in once drawing, and carries out secondary drawing, solves a drawing and moulding mould of tradition, large scale, deep-drawing is existed to the problem of part cracking.
