Abstract
The invention discloses a side flanging and punch withdrawing and separating structure for stamping die of automotive covering part. The side flanging and punch withdrawing and separating structure comprises an upper die body, a lower die body, a side flanging mechanism, an actuator on the punch withdrawing mechanism, and a punch withdrawing mechanism; the end part of the side flanging mechanism is provided with a side flanging cavity insert; the side flanging cavity insert tightly presses or loosens the product arranged on the punch withdrawing mechanism in the punching direction of the sideflanging in a side flanging way; the horizontal projection of the side flanging in the punching direction and the horizontal direction in which the punch withdrawing mechanism moves have an angle; andthe included angle is ranging from 30 degrees to 65 degrees. The structure has the beneficial effects that the projection of the side flanging mechanism and the punch withdrawing mechanism in the horizontal surface is separated as the specified angle, the length of the punch withdrawing mechanism is shortened, the side flanging mechanism and the punch withdrawing mechanism are compact, the spaceis saved, the structure is simplified, the cost is reduced and the processing and debugging are convenient.
Description
Technical field
What the present invention relates to is the diel of automobile panel, particularly be the side flanging and the punch withdrawing separate type of stamping die of automotive covering part.
Background technology
Automobile panel is made up of numerous products in the prior art, each product all need by draw, operation such as trimming and piercing die and flanging and restriking finishes.Each operation needs a mold to realize separately.
As shown in Figure 1, be to save die cost, the side flanging at the vertical flange of most of product P direction and Q direction transitional region place is everlasting and is made on the operation, and Here it is so-called " just top-cross cutter flange ".For guarantee side flanging mechanism flange finish after product can take out smoothly, conventional processing method has three kinds:
First kind is: as shown in Figure 2, press side flanging Q direction design punch withdrawing mechanism, the punch withdrawing mechanism of prior art and the structure of side flanging mechanism comprise: go up mould body 7; Following mould body 9; Last mould body 7 bottom surfaces are provided with driver 30 in side flanging mechanism and the punch withdrawing mechanism; Following mould body 9 inclined-planes are provided with mobile punch withdrawing mechanism.
Described side flanging mechanism comprises: be installed in driver 20 in the side flanging mechanism on mould body 7 bottom surfaces, on the inclined-plane that is pressed in side flanging mechanism slide block 4 one sides that in the side flanging mechanism slide in driver 20 bottom surfaces, side flanging mechanism slide block 4 opposite sides are equipped with side flanging die plate insert 3; Between driver 20 in the side flanging mechanism and side flanging mechanism slide block 4, be provided with the elastic device (figure does not show) that driving side flange body slide block 4 resets.Side flanging mechanism makes 3 pairs of products 1 of side flanging die plate insert finish the punching press side flanging along with last mould body 7 moves up and down.
As shown in Figure 2; on the driver 30 wedge guide plate 6 is being installed in the described punch withdrawing mechanism; this wedge guide plate 6 is along with last mould body 7 also moves up and down; the wedge guide plate 6 ' that the wedge guide plate 6 that moves up and down promotes in the punch withdrawing mechanism moves in the horizontal direction, and punch withdrawing mechanism is being moved as horizontal direction on the mould body 9 down.
Described punch withdrawing mechanism comprises: in mould body 9 inclined-plane upper supports down mobile punch withdrawing mechanism body 8 is arranged, be provided with wedge guide plate 6 ' in punch withdrawing mechanism body 8 one sides, punch withdrawing mechanism body 8 opposite sides are provided with punch insert 2; At the spring 5 that is provided with elastic reset down between mould body 9 and the punch withdrawing mechanism body 8, spring 5 one ends are arranged on down on the mould body 9 groove medial surfaces, and spring 5 other ends withstand on the punch withdrawing mechanism body 8.
Above-mentioned punch withdrawing mechanism and side flanging mechanism are arranged on same vertical upper-lower position, promptly so-called " primary and secondary Wedge mechanism ".
The shortcoming of above-mentioned so-called " primary and secondary Wedge mechanism " is: because the side flanging structure vertically itself is having certain-length, return and remove the punch part only greater than after the side flanging vertical structure length, the product 1 of processed side flanging could take out.Therefore, return and to remove bigger than side flanging structure that punch partly need do, above-mentioned prior art structure takes up room bigger, can't use for occasions with limited space.
Second kind is: do the rotating cam structure, its shortcoming is that design is complicated, and the margin of tolerance of permission is little, has improved manufacturing cost, and processing, debugging be difficulty comparatively.
The third is: vertical flange and side flanging are arranged in the different operations realize, its shortcoming is to need the extra mold that increases, and has improved die cost.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology; providing a kind of makes the projection in horizontal plane of side flanging mechanism and punch withdrawing mechanism be separated into set angle; dwindle punch withdrawing mechanism length; make side flanging mechanism and punch withdrawing mechanism structure compactness; saving takes up room, and makes things convenient for the side flanging and the punch withdrawing isolating construction of the stamping die of automotive covering part of processing and debugging.
The technical scheme that solves the problems of the technologies described above is: a kind of side flanging of stamping die of automotive covering part and punch withdrawing isolating construction, and described side flanging and punch withdrawing isolating construction comprise: go up mould body; Following mould body; Last mould body bottom surface is provided with driver in side flanging mechanism and the punch withdrawing mechanism; Following mould body is provided with punch withdrawing mechanism; Driver drives punch withdrawing mechanism and is moving as horizontal direction on the mould body down in the described punch withdrawing mechanism along with last mould body moves up and down, be provided with the side flanging die plate insert in side flanging mechanism end, the side flanging die plate insert move along with side flanging mechanism and along the side flanging pressing direction to being arranged on product side flanging in the punch withdrawing mechanism and compressing or unclamping; Form angle between the horizontal direction that the floor projection of described side flanging pressing direction and punch withdrawing mechanism move, this angle is 30 °～65 °.
The invention has the beneficial effects as follows: the present invention be different from prior art with side flanging mechanism direction and punch withdrawing mechanism design at same vertical upper-lower position; the present invention is that the projection in horizontal plane is separated into set angle with flange body and punch withdrawing mechanism; dwindle punch withdrawing mechanism length; make side flanging mechanism and punch withdrawing mechanism structure compactness; saving takes up room, and simplifies mould structure, saves die space; reduce cost, make things convenient for processing and debugging.Structure of the present invention is compared with the desired less margin of tolerance of rotating cam, has processing, manufacturing, debugs the advantage simple, that cost of manufacture is low.
The present invention not only is used for the stamping die of automotive covering part side flanging, is suitable for the situation that after side shaping punch has negative angle also equally.The present invention is at gusset, beater or beat-up, and car door, hood all can use on the product moulds such as central buttress brace, has the bigger scope of application.
