Abstract
The utility model relates to a guide pillar assembly and in particular relates to a guide pillar assembly for a stamping die. The guide pillar assembly for the stamping die comprises a guide pillar fixed on a fixing plate of a die plate, a guide sleeve is arranged on a connecting part of the guide pillar, a bushing is arranged between the guide sleeve and the guide pillar, and a plurality of transverse rollers are arranged on the side wall of the bushing. According to the guide pillar assembly, the bushing can be smartly arranged into a polygonal shape, the transverse rollers are arranged on the side wall of the bushing, so that the shape of the outer circumference of the connecting part of the guide pillar and the shape of the circumference of the guide sleeve are changed to be matched with the shape of the bushing, and the line-line contact is adopted instead of the original point-point contact, so that the contact area is increased; and therefore the guide pillar assembly disclosed by the utility model has the advantages that the rigidity is far higher than that of a ball bearing guide pillar assembly; and the prepressing amount of each roller is remarkably lower than each roller, and therefore the roller generates extremely small vibration amplitude during working, and the operation stability is greatly improved.
Description
Technical field
The utility model relates to a kind of guide pillar assembly, relates in particular to a kind of guide pillar assembly for diel.
Background technology
China mainly uses ball guide pillar assembly in the high speed stamping field at present, and its lining is provided with steel ball, has high accuracy and lower use cost.Simultaneously also exist some problems: because steel ball is a contact, so rigidity is lower, although can improve some rigidity by increasing the precompressed amount, the impact when steel ball pours is larger, can produce vibration, affects precision and the life-span of assembly.Therefore, in some rigidity and the higher diel of required precision, ball guide pillar assembly just is difficult to successfully manage, and has affected the normal use of mould, has reduced the production efficiency of enterprise.
Summary of the invention
In order to address the above problem, the utility model provides a kind of relatively high precision, rigidity and the stable guide pillar assembly that is used for diel.
To achieve these goals, the utility model is mainly solved by the following technical programs: a kind of guide pillar assembly for diel, comprise the guide pillar on the fixed head that is fixed on mould template, the connecting portion of guide pillar is provided with guide pin bushing, be provided with lining between guide pin bushing and described guide pillar, the cross-sectional circumference of described connecting portion is polygon; The cross section of described lining is polygon, and in it, periphery of week and described connecting portion is complementary; In the cross section of described guide pin bushing, week is polygon, and in it, periphery of week and described lining is complementary, and the sidewall of described lining is provided with several rollers, and the central shaft of roller is vertical with the central shaft of described lining.
As preferably, above-mentioned roller is embedded on described lining.
As preferably, Zhou Junwei regular hexagon in the cross section of the cross-sectional circumference of above-mentioned connecting portion, the cross section of lining and guide pin bushing.
The utility model is arranged to polygon with lining cleverly, be provided with the roller of horizontally set on its sidewall, and then shape and the described lining form fit in week in guide pillar connecting portion periphery and guide pin bushing have been changed, replaced original some point contact with the contact of line line, increased contact area, so there is following advantage in the utility model: 1, rigidity will be far away higher than ball guide pillar assembly; 2, the precompressed amount of roller will be significantly less than roller, so the vibration of roller when work is minimum, and operation stability significantly improves; Therefore because precision is high, stable, service life of the present utility model is considerably beyond ball guide pillar assembly, and can effectively reduce the wearing and tearing of other parts of mould, greatly improves the mold use life-span and increased the production efficiency of enterprise.

Fig. 2 is the A-A section cutaway view of Fig. 1.
Fig. 3 is that the B of Fig. 2 is to zoomed-in view.
The specific embodiment
Below in conjunction with accompanying drawing 1-3, the specific embodiment of the technical solution of the utility model is described in further detail.
Embodiment: a kind of guide pillar assembly for diel, comprise the guide pillar 4 on the fixed head that is fixed on mould template, the connecting portion 5 of guide pillar 4 is provided with guide pin bushing 1, is provided with lining 3 between guide pin bushing 1 and described guide pillar 4.The cross section of lining 3 is polygon, and in it, periphery of week and described connecting portion 5 is complementary; The cross-sectional circumference of connecting portion 5 is polygon; In the cross section of guide pin bushing 1, week is polygon, and in it, periphery of week and described lining 3 is complementary, and the sidewall of described lining 3 is provided with the roller 2 of horizontally set, and the central shaft of roller 2 is vertical with the central shaft of described lining 3.After assembling, roller 2 contacts with the outer ring of connecting portion 5 and the inner ring of guide pin bushing 1.Roller 2 is embedded on described lining 3, is convenient to processing and installs.
In order to make the utility model reach better rigidity and service life, Zhou Jun in the cross section of the cross section of the cross-sectional circumference of connecting portion 5, lining 3 and guide pin bushing 1 is designed to regular hexagon.
