Abstract
The utility model discloses a self-lubrication die guide column, comprising a die guide column; the external round of the die guide column is sheathed by a ball bearing holding frame; a die guide sleeve is sheathed on the external round of the ball bearing holding frame. The ball bearing holding frame is uniformly provided with a plurality of ball bearing holes which are internally provided with ceramic ball bearings; the die guide column is made of ceramic material: zirconia ZRO2 or silicon nitrides SI3N4; the ceramic ball bearing (3) is made of zirconia ZRO2. The self-lubrication die guide column uses the steel ball rolling principle, has the characteristic of motion along the axial direction and in the radial direction, replaces the sliding friction with the rolling friction, has smart rolling and small friction coefficient, realizes the interference assemble without clearance, has stable upper and lower motion and ensures the usage precision. As the die guide column and the ceramic ball bearing are made of the ceramic material ZRO2 and have self-lubrication and the advantage of small friction coefficient; therefore, the problems such as stress deformation, damaging the ball bearing and affecting the normal use of the die, etc. do not occur when the self-lubrication die guide column is used for a long time.
Description
Technical field
The utility model relates to a kind of diel parts guide pillar, is specifically related to a kind of self-lubricating guide-post of die-set.
Background technology
Diel of the prior art up and down is provided with guide pin bushing, guide pillar between the seat at mould, so that mould overlaps when descending and guide, thereby carries out punch forming work accurately.Common employed guide-post of die-set mostly is a steel material in diel, adopt movingly gapped between guide pin bushing and the guide pillar, because the mold work situation is relatively abominable, poor lubrication, make the wearability of grinding tool be subjected to certain infringement, can produce wearing and tearing between guide pin bushing and the guide pillar, sting card, thereby there are problems such as stress deformation easily in long-term use. reduce the mould positioning accuracy, influenced the normal use of pressing equipment.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is easy to install, is suitable for the self-lubricating guide-post of die-set of diel, solved mold guide sleeve and guide pillar damages easily, reduces the grinding tool positioning accuracy, influence the problem of pressing equipment use.
The technical scheme that the utility model adopted is, a kind of self-lubricating guide-post of die-set comprises guide-post of die-set, is with one at ball retainer on the guide-post of die-set cylindrical, and mold guide sleeve is enclosed within on the cylindrical of ball retainer.
The utility model feature also is,
Described guide-post of die-set adopts ceramic material, and material is zirconia ZRO2 or silicon nitride SI3N4.
Evenly distributed several ball holes that is provided with of described ball retainer are equipped with ceramic balls in the hole.
Described ball retainer is copper base, aluminium base or resin material.
Described ceramic balls material is zirconia ZRO2.
The utility model self-lubricating guide-post of die-set, the characteristics that have axially, radially can both move, the rolling friction of dependence structure has replaced the sliding friction between original mold guide sleeve and the guide pillar, roll each other flexibly, coefficient of friction is little, realizes the interference assembling of no gap, has guaranteed service precision.Solve mold guide sleeve and guide pillar damages easily, reduced the grinding tool positioning accuracy, influence the problem of pressing equipment use.
Description of drawings
Fig. 1 is the utility model self-lubricating guide-post of die-set structural representation;
Fig. 2 is the utility model self-lubricating guide-post of die-set ball retainer structural representation.
Among the figure, 1. guide-post of die-set, 2. ball retainer, 3. ceramic balls, 4. mold guide sleeve.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
A kind of self-lubricating guide-post of die-set of the utility model as shown in Figure 1, comprises guide-post of die-set 1, on guide-post of die-set 1 cylindrical, be with one at ball retainer 2, mold guide sleeve 4 is enclosed within on the cylindrical of ball retainer 2, and ball retainer 2 evenly distributed several ball holes that are provided with are equipped with ceramic balls 3 in the hole.
Guide-post of die-set 1 adopts ceramic material, and material is zirconia ZRO2 or silicon nitride SI3N4.
Described ball retainer 2 is copper base, aluminium base or resin material.
Described ceramic balls 3 materials are zirconia ZRO2.
The utility model 2 guide-post of die-set are that zirconia ZRO2 pottery is made up of t+c duplex structure, have very high intensity, and fracture toughness and thermal shock resistance and high self-lubricity are called as " ceramic steel ".The ZRO2 pottery also can be used as industrial unlubricated bearing, the parts of shaping usefulness on the powder metallurgy, stamping die etc.The thermal coefficient of expansion of SI3N4 ceramic material is little, therefore has thermal shock resistance preferably; In ceramic material, the bending strength ratio of SI3N4 is higher, and hardness is also very high, has self lubricity simultaneously, the advantage that coefficient of friction is little.
As shown in Figure 2, ball retainer 2 utilizes steel ball rolling principle, mixes the copper base, aluminium base, resin is a retainer, arranges in an orderly manner by certain angle and density, adopts groove circumference lock pearl technology, prevents that steel ball from coming off.
When the utility model is installed and used, earlier mold guide sleeve 4 is contained in the diel patrix, then guide-post of die-set 1 is installed in the hole of diel counterdie setting, again ball retainer 2 is contained on the guide-post of die-set 1, ceramic balls 3 on the ball retainer 2 is pushed outwards at this moment, the loose guide-post of die-set 1 that is inserted in, the mold guide sleeve 4 that will the be installed in the diel patrix at last ball retainer 2 of guide-post of die-set 1 of packing into, mold guide sleeve 4 is inwardly pushed away the ceramic balls on the ball retainer 23 again, eliminated the fit-up gap, under the ceramic balls 3 of ball retainer 2 rolled, ball retainer 2 moved up, mold guide sleeve 4 moves down, and it is packed into fully.After the utility model was installed, ball retainer 2 utilized steel ball rolling principle, and the characteristics that have axially, radially can both move rely on rolling friction to replace sliding friction, roll flexibly, and coefficient of friction is little, had realized the interference assembling of no gap, had guaranteed service precision.Because what guide-post of die-set 1 and ceramic balls 3 were adopted is zirconia ZRO2 ceramic material, has self lubricity, the advantage that coefficient of friction is little, so the utility model, long-term use stress deformation can not occur and the damage ball influences problems such as the normal use of mould.
