A buffer gasket (4) is arranged on the outer side of the pushing rod (3) in a sleeved mode and located between the top face (6) of the guide pillar body (1) and the inner side face (7) of the ball sleeve (5). The buffer gasket (4) comprises a rubber part (8) and gasket bodies (9), wherein the gasket bodies (9) are inlaid in the upper end and the lower end of the rubber part. The rolling guide pillar is long in service life.

Description

A kind of rolling guide pillar

Technical field

The utility model relates to progressive die accessory field, specifically a kind of rolling guide pillar.

Background technology

As shown in Figure 3, existing rolling guide pillar comprises ball cover 5, catch bar 3, guide pillar 1 and first stage clip 2.Described ball cover 5 is stressed downwards, makes catch bar 3 be pushed into the bottom in hole in the hole of guide pillar 1.The tail end of general described catch bar 3 is the plane, and the bottom in hole is taper surface, using long afterwards, the tail end edge of described catch bar has and can wear and tear, thereby reduced the press height of mould, but also the medial surface 6 that can make ball cover 5 contacts with the end face 7 of guide pillar 1 and clashes into, and makes medial surface 6 pressurizeds and breaks, and end face 7 all is damaged, thereby increase guide pillar 1 external diameter blocks ball cover 5 makes the rolling guide pillar break down easily, has reduced the service life of rolling guide pillar again.

The utility model content

(1) technical problem that will solve

The technical problems to be solved in the utility model is the service life that will improve the rolling guide pillar.

(2) technical scheme

For addressing the above problem, a kind of rolling guide pillar of the present utility model comprises ball cover, catch bar, guide pillar and first stage clip; Described ball overlaps an end and is connected with the top axial of catch bar, and the other end axially is enclosed within on the guide pillar, and the tail end of described catch bar is movably connected in the hole of guide pillar, and described first compression spring sleeve is upwards withstood the ball cover at the peripheral end of guide pillar; Be with buffering spacer in the described catch bar outside; Described buffering spacer is between the medial surface of the end face of guide pillar and ball cover, and described buffering spacer comprises rubber and pad, and described pad is embedded in rubber two ends up and down.

As further improvement of the utility model, the external diameter of described buffering spacer is 10MM.

As further improvement of the utility model, the material of described rubber is the hydrogenation nitrile rubber.

As further improvement of the utility model, the pad material is brass.

(3) beneficial effect

Rolling guide pillar of the present utility model, buffering spacer on the catch bar outer race, and be arranged between the medial surface of the end face of guide pillar and ball cover, by buffering prevent because of the tail end of guide pillar impaired after, reduce the height of mould punching press, avoid the ball cover to clash into mutually with the ball cover again and be subjected to deformation fracture, thereby reduced the fault rate of rolling guide pillar, improved service life.

Description of drawings

Fig. 1 is the structure chart of rolling guide pillar of the present utility model;

Fig. 2 is the structure chart of buffering spacer of the present utility model;

Fig. 3 be prior art the structure chart of rolling guide pillar;

1 is that guide pillar, 2 is that first stage clip, 3 is that catch bar, 4 is that buffering spacer, 5 is that ball cover, 6 is that end face, 7 is that medial surface, 8 is that rubber, 9 is pad among the figure.

The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.

As depicted in figs. 1 and 2, rolling guide pillar of the present utility model comprises ball cover 5, catch bar 3, guide pillar 1 and first stage clip 2; Described ball overlaps 5 one ends and is connected with the top axial of catch bar 3, and the other end axially is enclosed within on the guide pillar 1, and the tail end of described catch bar 3 is movably connected in the hole of guide pillar 1, and described first stage clip 2 is enclosed within guide pillar 1 a peripheral end and upwards withstands ball cover 5; Be with buffering spacer 4 in described catch bar 3 outsides; The external diameter of described buffering spacer 4 is 10MM, is arranged between the medial surface 7 of the end face 6 of guide pillar 1 and ball cover 5, and described buffering spacer 4 comprises rubber 8 and pad 9, and described pad 9 is embedded in rubber, and about in the of 8 two ends.The material of described rubber 8 is the hydrogenation nitrile rubber.Pad 9 materials are brass.When this structure can make described ball cover 5 and catch bar 3 promote downwards, what the medial surface 7 of ball cover 5 at first touched is buffering spacer 4, and drive buffering spacer 4 moves downward, described buffering spacer compensator or trimmer pressure, prevent the wearing and tearing between catch bar 3 tail ends and the bottom surface, hole, the height of punching press is protected, effectively avoided medial surface 7 to break with the direct contact impact of end face 6 again and be out of shape, reduced the fault rate of rolling guide pillar, thereby improved service life.

The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
