The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model suppresses two-way upsetting die, it comprises punch 1, die 2 and push rod 3, on punch 1 and die 2, be equipped with the die cavity wall, the forging and pressing die cavity is constituted by the die cavity wall on the punch 1, die cavity wall on the die 2 and the end face three of push rod 3, the structure that this many parts constitute die cavity is comparatively simple, also is die industry structure comparatively commonly used, does not therefore just do too much description in the structure to three's die cavity wall.
It also comprises the die guide the utility model; The die guide adopts tube-in-tube structure, die 2 sliding fits are in the die guide, be provided with the position limiting structure of restriction die 2 sliding strokes between die 2 and the die guide, position limiting structure can guarantee that die 2 can be smoothly and forge and press die cavities with other two parts compositions accurately; Also be provided with the elasticity ejector apparatus between die 2 and the die guide, this elasticity ejector apparatus can make die 2 and punch 1, push rod 3 form the forging and pressing die cavity smoothly can make die jack-up the smooth demoulding of finished product again; Die 2 be enclosed within on the push rod 3 and with push rod 3 sliding fits; Push rod 3 also is through in the die guide.
Because of die under the effect of elasticity ejector apparatus, its position can change, under two different states, the concrete structure of forging die is as follows:
As Fig. 1, shown in Figure 3, under die opening state, the elasticity ejector apparatus is in extended configuration, and die 2 is by jack-up, and push rod 3 keeps motionless, and the die cavity wall of die 2 will separate and form depression 4 with the end surface dislocation of push rod 3; This depression 4 can play the positioning action to blank 9 in the forging and pressing process, keep blank 9 to keep stable in the forging and pressing process.
As Fig. 2, shown in Figure 4, under the matched moulds state, blank 9 is subjected to the pressure of punch, and the elasticity ejector apparatus is in compressive state, and die 2 moves down, and the end face three of the die cavity wall on the punch 1, the die cavity wall on the die 2 and push rod 3 constitutes the forging and pressing die cavity.In when forging and pressing, the distortion of blank 9 drives die 2 and moves down, and until the end face closure of the die cavity wall and the push rod 3 of die 2, the die cavity wall on punch 1 is formed die cavity, so far blank 9 is pressed into finished product 10.During the demoulding, punch 1 lifts, and the elasticity ejector apparatus can boost die 2 and then drive finished product 10 demouldings.
Wherein, the position limiting structure of above-mentioned restriction die 2 sliding strokes is meant, is provided with projection 2.1 in the outside of die 2, and this projection 2.1 can be meant the annular radial protuberance that die 2 lower position are provided with in actual manufacturing; In the die guide, be positioned at the projection 2.1 on the die 2 top position place and below the position be respectively equipped with block 5.1 and supporter.By block 5.1 and supporter die 2 is carried out the spacing of axial direction respectively.
The preferable scheme of die guide is: it comprises die outer ring 5 and die packing ring 6; Die outer ring 5 be enclosed within die 2 outer and with die 2 sliding fits, above-mentioned block 5.1 is positioned on the die outer ring 5, above-mentioned supporter is a die packing ring 6, die packing ring 6 is positioned at die 2 belows and is connected and fixed with die outer ring 5 usefulness bolts, have stroke gap 7 between die packing ring 6 and die 2, move for die 2 in the trip gap 7.Push rod 3 passes the centre bore of die packing ring 6.
Above-mentioned elasticity ejector apparatus is preferably stage clip 8; After assemble with die packing ring 6 above-mentioned die outer ring 5, have the annular gap between both sidewalls, stage clip 8 is enclosed within outside the die packing ring 6 and is positioned at this annular gap, and an end and the die 2 of stage clip 8 offset, and the other end and die packing ring 6 offset.
For guaranteeing the quality of fit of punch 1 and die 2, the utility model also comprises the guiders that guiding punch 1 and die 2 precisely cooperate.These means also are the comparatively common technological means of die industry.
Above-mentioned guider specifically is meant, be provided with depression 5.2 in the end of die outer ring 5, the end of punch 1 is a plush copper 1.1, the shape coadaptation mutually of the depression 5.2 on the shape of this plush copper 1.1 and the die outer ring 5, during forging and pressing, in the depression 5.2 that plush copper 1.1 is inserted on the die outer ring 5, play guide effect.
As the safeguard measure of punch 1, it also comprises punch outer ring 5, and punch outer ring 5 is enclosed within outside the punch 1 and with punch 1 fixedlys connected; Therefore, as adaptive corrective measure, above-mentioned plush copper 1.1 comprises the protuberance of 5 ends, punch outer ring, when real work, in fact also is that this protuberance is realized guide effect with direct cooperation the on the die outer ring 5.
The preferred embodiment of the present utility model of the foregoing description position can not be regarded the restriction to the utility model claim as.Concrete structure of the present utility model allows variation, as: above-mentioned guider can also be a lead comparatively common in the industry, also can finish the guide effect in the utility model, but its structure is comparatively complicated, and cost is also higher, so does not adopt in this example; Above-mentioned supporter also can be the block structure; Or the like.All various of equal value replacements in the utility model independent claims are all dropped in the protection domain of the present utility model.
Secondly, elasticity ejector apparatus between die and the die guide not only can be with the smooth ejection device of finished product, and its die cavity wall is separated die jack-up with the end face of push rod at die opening state elasticity ejector apparatus to form depression, can play positioning action to blank when this is recessed in filler and in the punching course, keep the stable of blank;
In the punching course, blank deformation also carries out filling to the die cavity space of die part, and die is depressed, overlap with the end face of push rod with the die cavity wall of punch until the die cavity wall of die and to form complete die cavity, stamping procedure is finished, and after punch lifted, the elasticity ejector apparatus was with die jack-up, the finished product demoulding, can carry out subsequent processing, whole process automation degree height is convenient to enhance productivity, simplify workman's operational sequence, also be beneficial to the reduction working strength of workers.
