Abstract
The utility model discloses a kind of guide-post of die-set, comprise guide pillar, back-moving spring, steel ball sleeve and outer bush, steel ball sleeve is sleeved on one end of guide pillar, and the other end of guide pillar is provided with the shaft shoulder of outwardly convex, and back-moving spring is supported between the shaft shoulder and the end face of steel ball sleeve; Outer bush is set on steel ball sleeve; Steel ball sleeve is provided with some steel bead grooves along self line of travel, and the steel ball of steel ball sleeve is located in steel bead groove, and the degree of depth of steel bead groove is 2/3rds of diameter of the steel ball.In the utility model, steel ball sleeve is connected with all adopting to roll between guide pillar, outer bush, significantly can reduce the frictional force between steel ball sleeve and outer bush, guide pillar; Steel ball sleeve offers steel bead groove along its glide direction, and steel ball is located in steel bead groove, also connecting for rolling, dividing separately setting, have less frictional force relative to steel ball between adjacent steel ball.
Description
Technical field
The utility model relates to a kind of mold parts, particularly a kind of guide-post of die-set.
Background technology
One of important composition in the guide elements of guide pole stamping die, another composition is guide pin bushing, and their effects ensure that punch-die has fit clearance accurately in press work, requires that the gap of guide pillars and bushes is less than blade clearance.Guide pillar is arranged on the position away from module and holding pad.In order to improve guiding accuracy and part life, between guide pillar and outer bush, friction should be less.Punching die guide column mainly comprises guide pillar support, guide column sleeve and back-moving spring etc., realizes guiding and the antifriction function of diel.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of structure simple guide-post of die-set, solves the technical problem that in prior art, between guide pin bushing and guide pillar, frictional force is large.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of guide-post of die-set, comprise guide pillar, back-moving spring, steel ball sleeve and outer bush, described steel ball sleeve is sleeved on one end of guide pillar, the other end of guide pillar is provided with the shaft shoulder of outwardly convex, and described back-moving spring is supported between the shaft shoulder and the end face of steel ball sleeve; Described outer bush is set on steel ball sleeve; Described steel ball sleeve is provided with some steel bead grooves along self line of travel, and the steel ball of described steel ball sleeve is located in steel bead groove, and the degree of depth of steel bead groove is 2/3rds of diameter of the steel ball.
As further improvement of the utility model, the outer surface of described outer bush is provided with some hemisphere projection.
As further improvement of the utility model, the described steel ball sleeve end face corresponding with back-moving spring is provided with the oil storage box for steel ball lubrication, oil storage box offers some oil outlets, the setting corresponding with steel bead groove of described oil outlet.
Preferably, described oil storage box is hollow and annular.
Further, each oil outlet place of described oil storage box is equipped with leakproof seal circle.
Preferably, described leakproof seal circle is carbon seal ring.Carbon seal ring has good decay resistance relative to rubber ring.
Compared with prior art, the beneficial effect that the utility model reaches is: steel ball sleeve is connected with all adopting to roll between guide pillar, outer bush, significantly can reduce the frictional force between steel ball sleeve and outer bush, guide pillar; Steel ball sleeve offers steel bead groove along its glide direction, and steel ball is located in steel bead groove, also connecting for rolling, dividing separately setting, have less frictional force relative to steel ball between adjacent steel ball; The outer surface of outer bush arranges hemisphere projection, reduces the contact area with neighbor parts, reduces friction; An end face of steel ball sleeve arranges oil storage box, is lubricated in time steel ball by oil storage box, reduces steel ball wearing and tearing, ensures assembly precision.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure enlarged diagram at I place in Fig. 1.
In figure: 1, guide pillar; 2, back-moving spring; 3, steel ball sleeve; 4, outer bush; 5, hemisphere is protruding; 6, oil storage box; 7, leakproof seal circle; 8, steel ball; 9, the shaft shoulder.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 and Figure 2, a kind of guide-post of die-set 1, comprises guide pillar 1, back-moving spring 2, steel ball sleeve 3 and outer bush 4.Steel ball sleeve 3 is sleeved on one end of guide pillar 1, and the other end of guide pillar 1 is provided with the shaft shoulder 9 of outwardly convex, and back-moving spring 2 is supported between the end face of the shaft shoulder 9 and steel ball sleeve 3.Outer bush 4 is set on steel ball sleeve 3, and steel ball sleeve 3 is provided with some steel ball 8 grooves along self line of travel, and the steel ball 8 of steel ball sleeve 3 is located in steel ball 8 groove, and the degree of depth of steel ball 8 groove is 2/3rds of steel ball 8 diameter.Wear and tear for reducing steel ball 8, steel ball sleeve 3 end face corresponding with back-moving spring 2 is provided with the oil storage box 6 lubricated for steel ball 8, oil storage box 6 offers some oil outlets, oil outlet and the corresponding setting of steel ball 8 groove.Oil storage box 6 is in hollow and annular, and middle chamber is used for depositing lubricating oil, and each oil outlet place of oil storage box 6 is equipped with leakproof seal circle 7.Leakproof seal circle 7 preferably carbon seal ring, has good decay resistance relative to rubber ring.
For reducing the frictional force between outer bush 4 and other neighbor parts, the outer surface of outer bush 4 is provided with some hemisphere projections 5.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
