Abstract
The utility model relates to the hidden punch mechanism of a kind of guide pillar type, comprising: guide pillar, guide pin bushing, by force return pulling block, Anti-rotary block, drive block.Return pulling block is arranged on drive block by force, and Anti-rotary block is positioned at guide pin bushing top, and one end of Anti-rotary block embeds guide pillar inside, and guide pillar is nested in guide pin bushing inside.This mechanism structure is simple, compact, reasonable, can shorten the debugging cycle of mould, improves the precision of hidden punching, extends the service life of material pressing core.
Description
Technical field
The utility model relates to diel parts and manufactures field, the particularly hidden punch mechanism of a kind of guide pillar type.
Background technology
When Auto body panel die design manufactures, rush in the process of form mould in design containing larger angle is hidden, if the punching press angle of hidden punching is excessive, a difficult problem of hanging punch mechanism use without standard can be caused, nonstandard form can only be designed, the guiding form of the hidden punch mechanism of nonstandard form is difficult to debugging, greatly increases the cycle of die debugging.Even if the Wedge mechanism of the standard of use also can cause very large shock loading to material pressing core.So need to design a kind of running into the hidden punching of larger angle without the mechanism being easy to debugging guiding form during standards body.
Utility model content
The purpose of this utility model is, providing a kind of running into the hidden punching of larger angle without being easy to debugging guiding form during standards body, reducing design time, raising the efficiency, also improving the hidden hidden punch mechanism of guide pillar type rushing precision simultaneously.
To achieve these goals, the technical solution of the utility model is: the hidden punch mechanism of a kind of guide pillar type, comprising: guide pillar, guide pin bushing, by force return pulling block, Anti-rotary block, drive block.Return pulling block is arranged on drive block by force, and Anti-rotary block is positioned at guide pin bushing top, and one end of Anti-rotary block embeds guide pillar inside, and guide pillar is nested in guide pin bushing inside.
Retract block to be by force fixed on drive block by two measure-alike fastening bolts.
Guide pillar had not only served as guiding original paper but also had served as the effect of mechanism's slide block in this mechanism, and with patrix drive block for driver impels guide pillar to move back and forth, drive block serves driving effect to guide pillar.When material pressing core just starts binder, drive block press against guide pillar and starts to move along pressing direction, guide pin bushing can ensure that guide pillar moves back and forth along pressing direction when punching press, Anti-rotary block makes guide pillar can not rotate under external force, and return pulling block can pull guide pillar along pressing direction rollback after mould punching completes by force.
The beneficial effects of the utility model are, this mechanism structure is simple, compact, reasonable, can shorten the debugging cycle of mould, substantially reduce the design time of designer, improve the precision of hidden punching, extend the service life of material pressing core.
Accompanying drawing explanation
Fig. 1 is the hidden punch mechanism plane of guide pillar type.
Fig. 2 is the hidden punch mechanism axonometric drawing of guide pillar type.
Fig. 3 is guide pillar type hidden punch mechanism parts explosive views.
Above-mentioned number in the figure is described as follows:
1---guide pillar; 2---guide pin bushing; 3---return pulling block by force; 4---Anti-rotary block; 5---drive block; 6---work package; 7---material pressing core.
Detailed description of the invention
The technical solution of the utility model is described further by specific embodiment below in conjunction with accompanying drawing.
The hidden punch mechanism of a kind of guide pillar type, comprising: guide pillar 1, guide pin bushing 2, by force return pulling block 3, Anti-rotary block 4, drive block 5.Return pulling block 3 is arranged on drive block 5 by force, and Anti-rotary block 4 is positioned at guide pin bushing 2 top, and one end of Anti-rotary block 4 embeds guide pillar 1 inside, and it is inner that guide pillar 1 is nested in guide pin bushing 2.
The driving force of guide pillar 1 is provided by drive block 5, patrix starts to move downward, when material pressing core moves to the critical point just starting binder, drive block 5 starts to press against guide pillar 1 and moves along pressing direction, during motion, work package 6 starts to contact with product, until mould closes, in motion process, guide pin bushing 2 can ensure that guide pillar 1 moves back and forth along pressing direction when punching press, Anti-rotary block 4 can ensure that guide pillar 1 can not rotate under external force, and return pulling block 3 can pull guide pillar 1 along pressing direction rollback after mould punching completes by force.When returning back to the critical point that material pressing core and product depart from, guide pillar rollback puts in place can not have relative displacement with drive block 5 again, and patrix gets back to the top dead-centre of lathe afterwards, thus completes this punching press.
Claims (2)
1. the hidden punch mechanism of guide pillar type, is characterized in that, comprising: guide pillar, guide pin bushing, by force return pulling block, Anti-rotary block, drive block; Return pulling block is arranged on drive block by force, and Anti-rotary block is positioned at guide pin bushing top, and one end of Anti-rotary block embeds guide pillar inside, and guide pillar is nested in guide pin bushing inside.
2. the hidden punch mechanism of guide pillar type according to claim 1, is characterized in that, the described block that retracts by force is fixed on drive block by two measure-alike fastening bolts.
