Abstract
The utility model discloses a static pressure guide pillar used for presses in the press fields. The static pressure guide pillar comprises a guide pillar, wherein a guide sleeve is arranged at the periphery of the guide pillar and fixed in a central sleeve, and the center sleeve is fixed with a machine body, a lower end cover sheathed on the guide pillar is fixed on the lower side of the central sleeve; a sealing ring is arranged between the lower end cover and the guide pillar; a sealing ring press cover is also arranged on the lower side of the lower end cover; an annular oil groove is arranged at the joint surface of the lower end cover and the central sleeve; a plurality of axial oil holes communicated with the annular grooves are arranged in the central sleeve; radial oil holes communicated with the gap between the guide sleeve and the guide pillar are arranged on the guide sleeve in positions of different heights; the radial oil holes are connected with the axial oil holes; and a bushing matched with the guide sleeve is arranged outside the guide pillar. During operation, high-pressure oil forms a high-rigidity oil film at the joint surface of the guide pillar and the guide sleeve through the oil grooves, the axial oil holes and the radial oil holes to achieve better lubrication effect. The static pressure pillar can be used for a press and has the advantages of high guide accuracy and long service life.
Description
Technical field
The utility model relates to a kind of forcing press, particularly the guide pillar structure of forcing press.
Background technology
In the existing press technologies, the guide pillar structure that a kind of forcing press is arranged, mainly include guide pillar, guide pin bushing, center etc., guide pillar is built in the guide pin bushing by cooperation, guide pin bushing is built in the center by cooperation, and general lubricating oil directly enters the faying face of guide pillar and guide pin bushing by pipeline, mainly plays lubrication, hydraulic oil does not form high rigidity oil film from the end face one side draining of guide pin bushing.It is low that this guide pillar has a guiding accuracy, and the shortcoming of quick abrasion is bigger to the influence of forcing press overall performance.
The utility model content
The purpose of this utility model provides a kind of static pressure guide pillar that is used for forcing press, makes the PRESS PLUNGER service wear little, uses more reliable.
The purpose of this utility model is achieved in that the static pressure guide pillar that is used for forcing press, comprise guide pillar, the guide pillar periphery is provided with guide pin bushing, guide pin bushing is fixed in the center, center and fuselage fix, the center downside is fixed with the bottom end cover that is sleeved on the guide pillar, be provided with sealing ring between bottom end cover and the guide pillar, the bottom end cover downside also is provided with the sealing ring gland, faying face place with center on the bottom end cover is provided with annular oil-feed tank, be provided with the some axial oilhole of connecting annular oil groove in the center, be provided with the radial direction oil hole of connecting gap between guide pin bushing and the guide pillar in the differing heights position on the guide pin bushing, described radial direction oil hole links to each other with axial oilhole; Guide pillar is provided with the edge cover that matches with guide pin bushing outward.
During work, hydraulic oil enters in the annular oil-feed tank of gland by the road, enter respectively then in each axial oilhole, oilhole enters in the radial direction oil hole vertically again, enter then in the composition surface of guide pillars and bushes, rely on the effect of hydraulic oil, between the composition surface of guide pillars and bushes, form the oil film of high rigidity; In order to prevent that hydraulic oil from leaking, and utilizes sealing ring to seal pressurize; The edge cover can be changed separately, has improved the dependability of device, and compared with prior art, the utility model can play better lubrication, avoids the excessive wear between guide pillar, the guide pin bushing, and the facility that keep-up pressure have good precision.The utility model is applied on the forcing press, has the guiding accuracy height, the advantage of long service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A-A of Fig. 1 is to view.
Wherein: 1 guide pillar, 2 guide pin bushings, 201 radial direction oil hole, 3 center, 301 axial oilholes, 4 fuselages, 5 bottom end covers, 501 annular oil-feed tanks, 6 sealing ring glands, 7 edge covers, 8 sealing rings.
The specific embodiment
As figure, for being used for the static pressure guide pillar of forcing press, comprise guide pillar 1, guide pillar 1 periphery is provided with guide pin bushing 2, guide pin bushing 2 is fixed in the center 3, center 3 fixes with fuselage 4, center 3 downsides are fixed with the bottom end cover 5 that is sleeved on the guide pillar 1, be provided with sealing ring 8 between bottom end cover 5 and the guide pillar 1, bottom end cover 5 downsides also are provided with sealing ring gland 6, and the faying face place with center 3 on the bottom end cover 5 is provided with annular oil-feed tank 501, are provided with the some axial oilhole 301 of connecting annular oil groove in the center 3, be provided with the radial direction oil hole 201 of connecting gap between guide pin bushing 2 and the guide pillar 1 in the differing heights position on the guide pin bushing 2, described radial direction oil hole 201 links to each other with axial oilhole 301; Guide pillar 1 is outside equipped with the edge cover 7 that matches with guide pin bushing.
During work, hydraulic oil enters in the annular oil-feed tank of gland by the road, enter respectively then in each axial oilhole, oilhole enters in the radial direction oil hole vertically again, enters then in the composition surface of guide pillars and bushes, rely on the effect of hydraulic oil, between the composition surface of guide pillars and bushes, form the oil film of high rigidity, can play better lubrication, reduce wear, sealing ring can seal pressurize, avoids leaking.
