Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3, Figure 4, red impact forging press pickoff of the present invention, comprises top board 1, in the middle of top board 1, arrange tup 2, in the middle of tup 2, arrange drift, and drift is used for press work.Red impact forging press bed 4 is fixedly installed mould cylinder 5, mould 6 is set in mould cylinder 5, divide into top set bar 7 at mould 6, according to the shape of mould 6, push rod 7 can arrange top board and mould 6 lower contacts, be convenient to push rod 7 jack-up mould 6.Pull bar 3 is fixedly installed in tup 2 both sides, liftout crossbeam 8 is set below pull bar 3, in liftout crossbeam 8 both sides, through hole 3 14 is set, this pull bar 3 is through through hole 3 14, arrange screw 15 to fix in the both sides up and down of through hole 3 14, screw 15 can determine the position of liftout crossbeam 8, makes liftout crossbeam 8 when bottom dead centre, and supporting plate 10 is just in time positioned at push rod 7 lower surface.
As shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7, in the middle of liftout crossbeam 8, through hole 1 is set, through hole 1 arranges supporting plate 10, supporting plate 10 is slidably connected on the slide unit of through hole 1 both sides, this slide unit can be chute 19, also can be slide rail, such supporting plate 10 can slide on chute 19 or slide rail.Supporting plate 10 arranges through hole 2 11, arranges supporting plate guide post 12 5 times at mould cylinder, it is thick that this supporting plate guide post 12 is set to upper end, and lower end is thin, and connecting portion is set to wedge shape.This supporting plate guide post 12, through the through hole 2 11 on supporting plate 10, arranges elastomeric element in one end of supporting plate 10.As preferred embodiment of the present invention, this supporting plate 10 is set to two, supporting plate guide post 12 is set to two, supporting plate guide post 12 is each passed through the through hole 2 11 on supporting plate 10, at the two ends linking springs 13 of two supporting plates 10, two supporting plates 10 can be made to do relative motion, namely after two supporting plates 10 separate under the effect of supporting plate guide post 12, two supporting plates 10 can be made to reset, two supporting plate 10 both sides, spring can certainly be set respectively, also can make supporting plate 10 homing.
As shown in Figure 8, as preferred embodiment of the present invention, location-plate 16 is set below mould cylinder 5, location-plate 16 arranges through hole 4 17 and through hole 5 18, push rod 7 is through through hole 4 17, the direction of motion of push rod 7 can be determined, can only move up and down vertically, prevent push rod 7 direction of motion from offseting and causing mould 6 to damage; Supporting plate guide post 12, through through hole 5 18, plays fixation.
As shown in Figure 1, Figure 2, Figure 3 shows, in the specific implementation, when mould 6 put into by workpiece, tup 2 starts to move downward, drive pull bar 3 and liftout crossbeam 8 to move downward, by regulating the position of liftout crossbeam 8 on pull bar 3 in advance, when making liftout crossbeam 8 move to bottom dead centre simultaneously, supporting plate 10 on liftout crossbeam 8 just in time runs to the lower surface of push rod 7, at this moment, as shown in Figure 6, supporting plate 10 under the effect of spring 13 to intermediary movements, two supporting plates 10 are combined, just in time can hold up push rod 7.When after tup 2 punching press finished piece(s), start to move upward, at this moment top board 1 drives pull bar 3 and liftout crossbeam 8 to move upward, liftout crossbeam 8 just and top board 1, tup 2 be synchronized with the movement, so, supporting plate 10 on liftout crossbeam 8 just can hold up push rod 7, drive push rod 7 to move upward, and push rod 7 can eject mould 6 thus can take out workpiece in mould cylinder 5.Because supporting plate guide post 12 is that upper end is thick, lower end is thin, connecting portion is set to wedge shape, so when supporting plate 10 in upwards running through wedge shape position, supporting plate guide post 12 is extrapolated for supporting plate 10, when supporting plate 10 runs to supporting plate guide post 12 for upper end thicker part timesharing, namely when liftout crossbeam 8 runs to top dead-centre, supporting plate guide post 12 two supporting plates 10 separately, neutral gear is formed between two supporting plates 10, as shown in Figure 7, supporting plate 10 leaves the lower surface of push rod 7, at this moment, push rod 7 moves downward due to the effect being subject to gravity, thus mould 6 is moved downward, get back in mould cylinder 5, so just complete the punching course of a workpiece, circulation like this.
By reference to the accompanying drawings embodiment of the present invention is explained in detail above; but the present invention is not limited to above-mentioned embodiment; to those skilled in the art, can also do some modification and improvement under the premise of not departing from the present invention, these also should be considered as belonging to protection scope of the present invention.
