Description
Technical field
The present invention relates to die holder field, be specifically related to a kind of ball-type die holder.
Background technology
For many years, die holder is important instrument always, and a lot of daily necessities be unable to do without all needs die holder, does not have a lot of product without die holder.After the downward operation of upper bolster of die set in the past, reset and there is no specific parts, allow upper bolster reset more difficult, reduce the process velocity of stamping die, reduce productivity effect.
Summary of the invention
For the problems referred to above, the invention provides one and solve the problem, and easy to use, can be used for Precision Machining, long service life, roller die holder easily changed by guide pillar guide pin bushing.
Realize technical scheme of the present invention
Roller die holder, comprise upper bolster and die shoe, upper bolster is arranged on die shoe upper end, described upper bolster upper end is provided with briquetting, on, two guide pillars are provided with between die shoe, the center line of two relatively upper and lower die holders of guide pillar is symmetrical, guide pillar upper end is arranged in upper bolster, guide pillar upper external is set with guide pin bushing, retainer is provided with between guide pin bushing and guide pillar, retainer is connected with guide pillar, ball is provided with in retainer, ball side and guide pillar outer surface, guide pin bushing inner surface all contacts, ball lower end is provided with spring, lower spring end contacts with die shoe upper surface, end in contact under spring upper end and retainer, described guide pin bushing outer surface upper bolster lower end is provided with groove, upper bolster lower end is provided with some pressing plates, pressing plate is provided with boss, boss is arranged on groove, pressing plate is connected with die shoe with upper bolster by screw.
Between described upper and lower die holder, be provided with equal height cushion block between two guide pin bushings, described equal height cushion block adopts resilient material.
Be provided with in described retainer and keep circle, ball is contained in and keeps in circle.
Described spring upper end is arranged between guide pillar and guide pin bushing.
Described pressing plate is at least 2.
Adopt such scheme, the center line of two relatively upper and lower die holders of guide pillar is symmetrical, mold tilt is prevented during punching press, retainer is provided with between guide pin bushing and guide pillar, retainer is connected with guide pillar, ball is provided with in retainer, ball side and guide pillar outer surface, guide pin bushing inner surface all contacts, ball and guide pillar, very close to each other between guide pin bushing, thus guiding accuracy is improved, and the frictional property between guide pillars and bushes can be made to become sliding friction from original rolling friction, friction factor reduces, thus improve the service life of guide-post of die-set and guide pin bushing, guide pin bushing inboard outer upper end is provided with groove, upper bolster lower end is provided with some pressing plates, pressing plate is provided with boss, boss is arranged on groove, by the cooperation of boss and groove, prevent upper bolster and guide pin bushing from coming off, improve the connection fastness of upper bolster and guide pin bushing, pressing plate is connected with upper bolster by screw, facilitate the dismounting of guide pillars and bushes, when guide pillar or guide pin bushing damage, be convenient for changing.
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in the figure, roller die holder, comprise upper bolster 1 and die shoe 2, upper bolster 1 is arranged on die shoe 2 upper end, upper bolster 1 upper end is provided with briquetting 3, pressure 3 is stress point, on, two guide pillars 4 are provided with between die shoe, the center line of two relatively upper and lower die holders of guide pillar 4 is symmetrical, mold tilt is prevented during punching press, guide pillar 4 upper end is arranged in upper bolster 1, guide pillar 4 is not through the top of upper bolster 1, guide pillar 4 upper external is set with guide pin bushing 5, retainer 6 is provided with between guide pin bushing 5 and guide pillar 4, retainer 6 is connected with guide pillar 4, ball 7 is provided with in retainer 6, ball 7 side and guide pillar 4 outer surface, guide pin bushing 5 inner surface all contacts, ball 7 and guide pillar 4, very close to each other between guide pin bushing 5, thus guiding accuracy is improved, and the frictional property between guide pillar 4 and guide pin bushing 5 can be made to become sliding friction from original rolling friction, friction factor reduces, thus improve the service life of guide-post of die-set 4 and guide pin bushing 5, ball 7 lower end is provided with spring 8, spring 8 lower end contacts with die shoe 2 upper surface, spring 8 upper end and retainer 6 times end in contact, spring 8 reduces vibrations, when distress resolves on pressure block 3, retainer 6 moves upward under the effect of spring 8, because retainer 6 is connected with guide pillar 4, thus guide pillar 4 is also moved upward, return to initial seat, guide pin bushing 5 inboard outer upper end is provided with groove, upper bolster 1 lower end is provided with some pressing plates 9, pressing plate 9 is provided with boss, boss is arranged on groove, by the cooperation of boss and groove, prevent upper bolster 1 and guide pin bushing 5 from coming off, improve the connection fastness of upper bolster 1 and guide pin bushing 5, pressing plate 9 is connected with upper bolster 1 by screw 10, facilitate the dismounting of guide pillar 4 and guide pin bushing 5, when guide pillar 4 or guide pin bushing 5 damage, be convenient for changing.
Preferably, between upper and lower die holder, equal height cushion block 11 is provided with between two guide pin bushings 5, equal height cushion block 11 adopts elastomeric material to make, support upper and lower die holder, when on briquetting 3 during distress resolves, the cushion block 11 by the time that elastomeric material is made, under the effect of cushion block elastic force, can make upper bolster 1 return on original seat.
Further, be provided with and keep circle in retainer 6, ball 7 is contained in and keeps, in circle, ensureing the seat of ball 7 in retainer 6, prevents the random vibration of ball.
Further, spring 8 upper end is arranged between guide pillar 4 and guide pin bushing 5, improves the stability that spring 8 works, is conducive to spring 8 elastic force and guide pillar 4 is returned to original seat, and less vibrations.
Further, pressing plate 9 is at least 2, and improve the connective stability of guide pin bushing 5 and upper bolster 1, it is unnecessary to prevent.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
