Abstract

The utility model relates to a guide pillar for stamping die. The guide pillar for the stamping die comprises a guide pillar body and an annular tube which is matched with and sleeved on the guide pillar body. The guide pillar for the stamping die is characterized in that the guide pillar body comprises a guide pillar upper end, a guide pillar middle portion and a guide pillar lower end, wherein the diameter of the guide pillar middle portion is greater than the diameter of the guide pillar upper end and the diameter of the guide pillar lower end, the diameter of the guide pillar upper end is the same as the diameter of the guide pillar lower end, a plurality of holes are formed in the periphery of the annular tube, a steel ball is placed in each of the holes, a spring is further sleeved at the guide pillar upper end, one end of the spring abuts against the bottom of the annular tube, and the other end of the spring abuts against the upper end of the guide pillar middle portion. The guide pillar for the stamping die is used as a guide pillar for stamping an upper die and a lower die, steel balls are arranged in the guide pillar annular tube, the spring is used for maintaining that the steel balls are at proper positions and move up and down, and thus no lubricating oil is needed to keep the guide pillar in a lubrication state.

Description

A kind of guide pillar for diel

Technical field:

The utility model relates to a kind of improvement of diel, relates in particular to a kind of guide pillar for diel.

Background technology:

When utilizing the diel stamping products, if in the time of higher to the required precision of product, between upper/lower die, increase guide pillar, guide pillar can play the effect of location upper and lower mould, guide pillar is in the process that helps the upper and lower mould location, because what adopt is a single cylinder axis, need to keep lubricating status, the lubricated of guide pillar need to be offered a fuel feed hole between upper and lower mould, be used for ceaselessly adding lubricating oil, to keep the lubricated of guide pillar, therefore operation is comparatively loaded down with trivial details, production efficiency is low, and input cost is large.

Summary of the invention:

The technical problem that the utility model solves provides a kind of machining accuracy of guaranteeing, need not to add lubricating oil, a kind of guide pillar for stamping die that Cost reduction drops into.

The technical scheme in the invention for solving the technical problem is: a kind of guide pillar for diel, comprise that guide pillar body and engage sleeves are connected on the sleeve pipe on the guide pillar body, described guide pillar body comprises the guide pillar upper end, guide pillar middle part and guide pillar lower end, the diameter at described guide pillar middle part is greater than the diameter of guide pillar upper end and guide pillar lower end, the guide pillar upper end diameter equals the guide pillar lower end diameter, the periphery of described sleeve pipe offers several holes, in this hole, be placed with steel ball, also be socketed a spring in described guide pillar upper end, one end of described spring withstands the bottom of sleeve pipe, and the other end of spring withstands the upper end at guide pillar middle part.

Further, in order to allow spring in flexible up and down process, guarantee that steel ball has one reasonably to move up and down the position, described hole is equidistantly offered, and is the bar shaped array distribution along the sliding sleeve periphery.

Further, for guide pillar is positioned, offer screw hole on the top of described guide pillar upper end and the bottom of guide pillar lower end.

The beneficial effects of the utility model are: the utility model is used for the guide pillar of punching press upper/lower die, by the steel ball that arranges in guide pin bushing, utilizes spring to keep steel ball to be in a suitable position that moves up and down, and need not to add lubricating oil and can keep lubricating status.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is that upper and lower mould merges schematic diagram in the utility model duty;

Fig. 3 is that upper and lower mould separates schematic diagram in the utility model duty.

Among the figure: 1, patrix 2, line position cover 3, guide pillar body 31, guide pillar upper end 32, guide pillar middle part 33, guide pillar lower end 34, screw hole 4, counterdie 5, sleeve pipe 51, steel ball 6, spring.

The specific embodiment:

A kind of guide pillar for diel as shown in Figure 1, comprise that guide pillar body 3 and engage sleeves are connected on the sleeve pipe 5 on the guide pillar body, described guide pillar body 3 comprises guide pillar upper end 31, guide pillar middle part 32 and guide pillar lower end 33, the diameter at described guide pillar middle part 32 is greater than the diameter of guide pillar upper end 31 and guide pillar lower end 33, guide pillar upper end 31 diameters equal guide pillar lower end 33 diameters, the periphery of described sleeve pipe 5 offers several holes, in this hole, be placed with steel ball 51, also be socketed a spring 6 in described guide pillar upper end, one end of described spring withstands the bottom of sleeve pipe 5, and the other end of spring withstands the upper end at guide pillar middle part 32.

Further, in order to allow spring 6 in flexible up and down process, guarantee that steel ball 51 has one reasonably to move up and down the position, described hole is equidistantly offered, and is the bar shaped array distribution along the sleeve pipe periphery.

Further, for guide pillar is positioned, offer screw hole 34 on the top of described guide pillar upper end 31 and the bottom of guide pillar lower end 33.

Shown in Fig. 2 and 3, the utility model is used for the guide pillar of punching press upper/lower die, this guide pillar is fixed between patrix 1 and the counterdie 4, one line position cover 2 also is set in the base plate of patrix 1, overlap 2 pressing sleeve pipes 5 by line position and move downward, by the steel ball 51 in guide pin bushing 5 interior settings, utilize spring 6 to keep steel balls to be in a suitable position that moves up and down, need not to add lubricating oil and can keep lubricating status, prevent from producing when upper and lower mould from dividing mould stuck phenomenon and produce.

It is emphasized that, it more than is better implementation column of the present utility model, be not that utility model is done any type of restriction in appearance, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
