Description
Technical field
The present invention relates to a kind of diel, particularly a kind of Bending in Progressive Die mechanism.
Background technology
Progressive die, is made up of multiple stations, and each station is associated in order completes different processing, in the one stroke of punch press
It is middle to complete a series of different punch process.It has very high productivity ratio, and safe operation is easy to automation.At present, extensively
Applied to all kinds of auto parts electric parts of production etc..In progressive die production process, bending punch-pin is often fixed on punch-pin and fixed
On plate, when punching parts both sides, which have, to be bent less than an angle of 90 degrees, part is easy to hang on bending punch-pin in punching course, therefore
Normal feeding of the progressive die in punching course can be influenceed.Meanwhile, existing bending punch-pin is integrally fixed on punch retainer, with
The feed level of back manufacturing procedure is different, causes feeding difficult, so that the normal operation of progressive die is influenceed, influence production effect
Rate.
The content of the invention
It is an object of the invention to provide a kind of Bending in Progressive Die mechanism, Bending in Progressive Die low-angle zero can be efficiently solved
Feeding problems during part.
A kind of Bending in Progressive Die mechanism, including it is punch retainer, wedge, stripper, bending punch-pin, bending die, spacing
Plate；Wherein punch retainer vertically moves reciprocatingly in the presence of external force, and stripper is located at below punch retainer,
Wedge sets two and upper end is fixed on punch retainer through stripper, and wedge lower surface is set to inclined-plane, bends punch-pin
It is fixed on stripper bottom surface and between two wedges, bending die is divided into left and right two, the relative one side in left and right two
The profile matched with bending punch-pin shape is set to, the upper surface of left and right two sets the inclined-plane matched with wedge lower surface, limit
Position plate sets two and positioned at stripper both sides, and limiting plate upper end sets the raised displacement for being used to limit stripper.
Compared with the existing technology being processed using bending punch-pin, present invention bending punch-pin is fixed on stripper,
And stripper realizes the unification with back manufacturing procedure feed level by limiting plate；The stripper of the present invention can be with simultaneously
When bending punch-pin is lifted up, facilitate the separation of workpiece and bending punch-pin by punching press break gear thereunder.
The present invention is described further with reference to Figure of description.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the floating nail schematic diagram of stripper nail pressing stripper.
Fig. 3 is limiting plate schematic diagram.
Embodiment
As shown in Figure 1, 2, 3, a kind of Bending in Progressive Die mechanism, including die shank 1, upper clamping plate 2, backing plate 3, punch retainer
14th, wedge 13, stripper 6, limiting plate 18, bending punch-pin 12, bending die 11, die block 7, backing plate 9, die shoe plate
10th, the floating nail 17 of guide pillar 5, guide pin bushing 4, stripper nail pressing 16, stripper.Die shank 1 is assemblied on upper clamping plate 2, upper clamping plate 2, pad
Plate 3, punch retainer 14 are positioned by pin and screw, and wedge 13 is positioned by punch retainer 14, lower end and bending die
11 inclined-plane is engaged, and die shoe plate 10, backing plate 9, die block 7 are positioned by pin screw, and stripper 6 is positioned over cavity plate
The top of fixed plate 7, sets inner guiding post guide pin bushing to be oriented to for stripper 6, inner guiding post is interference fitted with stripper 6, interior guide pin bushing and cavity plate
Fixed plate 7 is interference fitted, and limiting plate 18 is arranged at the both sides of die block 7, under being fixed on by limit base 19 and banking pin 20
Die holder plate 10, controls the up height of stripper 6 by limiting plate 18 when upper mould is up, stripper nail pressing 16 is fixed by punch-pin
Plate 14 is contacted with stripper 6, and the top of stripper nail pressing 16, which is provided with above spring, spring, is provided with nut 15, and the floating nail 17 of stripper leads to
Cross die block 7 to contact with stripper 6, below provided with spring, spring is placed in the hole of lower bolster 9, bend punch-pin 12
It is fixed by bolts on stripper 6, is moved with stripper 6, bending die 11 is arranged in die block 7, it is fixed by screw 8
Position, the end of screw 8 is cased with spring, and die block 7 is provided with two gathering sills, and the two ends of bending die block 12 are provided with two with being oriented to
The lug that groove coordinates, the lug is absorbed in gathering sill.Bending die can be made by the pulling force of spring when upper mould is up along guiding
Groove is to two Slideslips, and the inclined-plane of bending die 11 coordinates with the inclined-plane of wedge 13, guide pin bushing 4 be arranged on the surrounding of upper clamping plate 2 with
Guide pillar 5 is connected.
Die shank 1 is connected with external pressure machine drive shaft.
Stripper 6 makes part be separated from bending punch-pin 12 in the die sinking of punching course.
The course of work of mould is：Forcing press driving die shank 1 is descending, and stripper nail pressing 16 is contacted with stripper 6 first, is pushed away
Dynamic stripper 6 is moved downward, until bending punch-pin 12 completes binder, press ram is continued traveling downwardly, the top of stripper nail pressing 16
Spring stress shrink, the contact of incline plane of wedge 13 and bending die 11 promotes bending die 11 along gathering sill to middle slip,
Until press ram reaches that lower initial point completes bending forming.When forcing press is up, the first motion, bending die 11 upwards of wedge 13
To two Slideslips in the presence of by spring tension, stripper 6 is because of the still remains stationary of the pressure by stripper nail pressing 16, pressure
Machine sliding block continues up, and stripper nail pressing 16 is moved upwards, and stripper 6 is moved upwards in the presence of the floating nail 17 of stripper, together
When billot motion upwards synchronous with stripper 6 in the presence of floating guiding stock pin, press ram continues to go upward to initial point, this
When, stripper 6 is contacted with limiting plate 18, and billot course feed, whole BENDING PROCESS terminates.
