Abstract
The invention discloses the shaping punching compression technology of upwards flanging bore on a kind of floor for sedan car part, comprise the following steps: 1) drawing: drawing modeling is carried out to plate, form boss; 2) punching: stamp out bottom outlet at described boss end face; 3) shaping downwards; 4) trimming: complete trimming with downward trimming on same set of mould.The moulding process of flanging bore is become downward shaping by upper overturning by drawing modeling by the present invention, shaping terrace die and holding pad are at patrix, correcting die is at counterdie, because correcting die is fixed structure, thus make mould structure replace traditional counterdie bascule by lower die fixing structure, fixing lower die structure can with other trimming structure composite, overturning process can be compounded on same set of mould with other trimming operation complete, compare with traditional handicraft and decrease one set of die, make mould structure Compound Degree high, thus improve production efficiency, reduce production cost.
Description
Technical field
The present invention relates to rapid metallic prototyping technique, refer to the shaping punching compression technology of upwards flanging bore on a kind of floor for sedan car part particularly.
Background technology
Sheet Metal Forming Technology is widely used in auto manufacturing, many coverings in body in white and interior panels are all utilize mould to be stamped to form on forcing press, usually, complicated part generally all needs just to realize forming parts through multiple working procedures such as drawing modeling, trimming, flange, shapings.Floor part shape structure on body in white is comparatively complicated, and the aperture on the part of floor often can be designed to the architectural feature to upper overturning (relative to pressing direction).Upwards the conventional molding process of flanging bore comprises the following steps: 1) first process on plane plate and treat flange bottom outlet; 2) trimming; 3) to upper overturning; 4) trimming.Due to reasons in structure, in this flanging bore tradition forming process, flange die is at patrix, flanging die and holding pad are at counterdie, because holding pad is movable part, so lower mould is not fixing, and trimming class mould requires that counterdie needs to make fixed part, so carry out driving row into the operation of upper overturning and trimming operation score to bottom outlet, therefore, the overturning process of this technique and trimming operation can not be carried out in one set of die, need independent hole flanging mold, there is inefficiency, and the shortcoming that production cost is high.
Summary of the invention
Object of the present invention is exactly the shaping punching compression technology that will provide upwards flanging bore on a kind of floor for sedan car part, this process increases mould Compound Degree, decreases diel quantity, improve operating efficiency.
For achieving the above object, the technical solution used in the present invention is: the shaping punching compression technology of upwards flanging bore on a kind of floor for sedan car part, comprises the following steps:
1) drawing: carry out drawing modeling to plate, forms boss;
2) punching: stamp out bottom outlet at described boss end face;
3) shaping downwards: downward shaping is carried out to the boss after above-mentioned punching, shaping terrace die and holding pad are at upper mould, correcting die is at lower mould, it is recessed that middle part is protruded in periphery, shaping terrace die bottom surface, recessed middle part, correcting die end face periphery is protruded, in the middle part of correcting die end face, the matching form of the shape of projection and the periphery projection of shaping terrace die bottom surface closes, when starting shaping, in the middle part of correcting die end face, projection is against in bottom outlet along bottom surface, the periphery projection of shaping terrace die bottom surface is against bottom outlet outer end face, and punching press forms upwards flanging bore;
4) trimming: complete trimming with downward shaping step on same set of mould.
The present invention is directed to the automated production of the large-scale covering stamping parts of car, by drawing modeling, the moulding process of flanging bore is become downward shaping by upper overturning, shaping terrace die and holding pad are at patrix, correcting die is at counterdie, because correcting die is fixed structure, thus make mould structure replace traditional counterdie bascule by lower die fixing structure, fixing lower die structure can with other trimming structure composite, trimming can be compounded on same set of mould with other trimming operation complete, adopt this forming method, compare with traditional handicraft and decrease one set of die, make mould structure Compound Degree high, thus improve productive temp and efficiency, reduce production cost.
Further, described step 3) in, in cylindric vertical protrusion in the middle part of described correcting die end face, in cylindric vertically recessed in the middle part of described shaping terrace die bottom surface.
Further, described step 1) in, the round boss of described boss to be section be isosceles trapezoid, described boss sidewall drafting angle α is 25 ° ~ 35 °, and the height of described boss is higher than flanging bore height to be formed 1 ~ 3mm.
Accompanying drawing explanation
Fig. 1 is the drawing modeling operation schematic diagram to upper overturning circular hole shaping punching compression technology on a kind of floor for sedan car part.
Fig. 2 is the bottom outlet manufacturing procedure schematic diagram to upper overturning circular hole shaping punching compression technology on a kind of floor for sedan car part.
Fig. 3 be on a kind of floor for sedan car part to upper overturning circular hole shaping punching compression technology downward trimming schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, is convenient to more clearly understand the present invention, but they do not form restriction to the present invention.
To a shaping punching compression technology for upper overturning circular hole on floor for sedan car part, comprise the steps:
Step 1), as shown in Figure 1, first with drawing die plate is placed on forcing press and carries out drawing modeling: do a round boss 1 large compared with flanging bore in the position of flange circular hole 2 to be processed, the section of this boss 1 is isosceles trapezoid, boss 1 sidewall drafting angle α preferably 25 ° ~ 35 °, more preferably 30 °, to guarantee that drawing and moulding does not ftracture; Boss 1 end face exceeds h than the height of flange circular hole 2 to be processed, and h is 1 ~ 3mm preferably, more preferably 1mm, to guarantee that rear operation can shaping downwards.
Then, carry out step 2), as shown in Figure 2, stamp out circular bottom outlet 3 with forcing press in described boss 1 end face centre.
Then, carry out step 3), as shown in Figure 3, forcing press carries out downward shaping to the boss 1 after above-mentioned punching, shaping terrace die 5 and holding pad 6 are at upper mould, correcting die 4 is at lower mould, middle part is protruded in cylindric vertically recessed in periphery, shaping terrace die 5 bottom surface, recessed middle part, correcting die 4 end face periphery is cylindric vertical protrusion, in the middle part of correcting die 4 end face, the matching form of the shape of projection and the periphery projection of shaping terrace die 5 bottom surface closes, when starting shaping, in the middle part of correcting die 4 end face, projection is against in bottom outlet 3 along bottom surface, the periphery projection of shaping terrace die 5 bottom surface is against bottom outlet 3 outer end face, in downward reforming process, holding pad 6 is under the driving of flexible member, move downward, part is pushed down with correcting die 4, then, shaping terrace die 5 is under the driving of forcing press, move downward, together with correcting die 4, round boss 1 is shaped to upper overturning circular hole 2 downwards, and trimming is completed on this same set of shaping mould, obtain final products.
