Abstract
The invention relates to a trimming method for an automobile beam part. During the drawing process for the automobile beam part, a lug boss is processed on a drawing convex mould; the position of the lug boss is corresponding to the to-be-trimmed position of the automobile beam part; and the vertical trimming for the automobile beam part is realized by the relative motion between the drawing convex mould and a drawing concave mould.
Description
Technical field
The present invention relates to a kind of trimming method of automobile beam piece.
Background technology
Along with the develop rapidly of auto industry, increasingly high for the product quality requirement of automobile beam piece.In the prior art, during the processing automobile beam piece, adopt the side trimming method of wedge deburring.
Summary of the invention
The object of the invention is to provide a kind of trimming method of automobile beam piece, combines with drawing operation, adopts the method for upright deburring, effectively reduces die cost.
Realize the technical scheme of the object of the invention:
A kind of trimming method of automobile beam piece is characterized in that: in the drawing operation of automobile beam piece, be processed with boss on the punch drawing, the position of this boss needs trim position corresponding with the automobile beam piece; Through drawing protruding film and the relative motion of drawing die, realize the upright deburring of automobile beam piece.
Match with the boss on drawing punch, be processed with depression on the die drawing.
During deburring, punch and the cutting edge height that draws die are drawn in corresponding adjustment.
Draw punch and draw between the die gap even.
After the upright deburring, again the automobile beam piece is carried out flanging and restriking.
The beneficial effect that the present invention has:
The present invention is processed with boss drawing on the punch, through drawing protruding film and the relative motion of drawing die, realize the upright deburring of automobile beam piece; Deburring combines with drawing operation, thereby avoids adopting the wedge deburring, practices thrift 2 cover wedges; Save die cost, reduce die cost.
Description of drawings
Fig. 1 is for realizing the mould structure sketch map of the inventive method;
Fig. 2 draws the position view that boss is set on the punch.
The specific embodiment
As shown in Figure 1, in the drawing operation of automobile beam piece, be processed with boss 2 on the punch 1 drawing, as shown in Figure 2, the position 3 that is provided with of this boss needs trim position corresponding with the automobile beam piece; Match with the boss on drawing punch, be processed with depression on the die drawing, draw punch and draw and keep the gap even between the die.
During deburring, punch and the cutting edge height that draws die are drawn in corresponding adjustment.Through drawing protruding film and the relative motion of drawing die, realize the upright deburring of automobile beam piece.For automobile beam piece deburring face and the material limit of punch cutting edge, can adopt upright trimming method provided by the present invention greater than ± 30 degree.
After the upright deburring, can carry out flanging and restriking to the automobile beam piece more as required, turn down boss and flatten, thereby guarantee that the product profile is consistent with product data.
Claims (5)
