Abstract

The utility model relates to a kind of injection machine selflubricating steel bushing having oil groove, comprise cylinder-shaped body and graphite embedded hole, the cylindrical side of described cylinder-shaped body is evenly arranged the graphite embedded hole of multiple embedded graphite, inside and outside two side in the middle part of described cylinder-shaped body all circumferentially has horizontal oil groove, the inner side of described cylinder-shaped body circumferentially evenly has some and is vertically furnished with vertical oil groove, has oilhole the regioselectivity that this vertical oil groove is crossing with horizontal oil groove.The utility model has offered oil groove on the basis of graphite lubrication, substantially increases lubrication effect, and wear-resisting property there has also been raising, operating lifetime.

Description

A kind of injection machine selflubricating steel bushing having oil groove
Technical field
The utility model relates to injection machine steel bushing field, particularly relates to a kind of injection machine selflubricating steel bushing having oil groove.
Background technique
Injection machine is a kind of manufacturing mechanism conventional in modern industry, when the rotatable parts on injection machine and other build-up member (as: moving pattern plate, rear pattern plate etc.) are rotationally connected, usual needs first install steel bushing on the endoporus of this build-up member (i.e. moving pattern plate, rear pattern plate etc.), then rotatable parts are assembled in steel bushing, to increase its wear resistance.
Steel bushing in use needs to lubricate, and prevents stuck, and reduce frictional force, existing technology embeds graphite in the outer side wall of steel bushing, but graphite in use consumes soon, and supplementary replacing is cumbersome, can not play lubrication effect well.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of injection machine selflubricating steel bushing having oil groove, and oil groove has been offered on the basis of graphite lubrication, has substantially increased lubrication effect, wear-resisting property there has also been raising, operating lifetime.
The utility model solves the technological scheme that its technical problem adopts: provide a kind of injection machine selflubricating steel bushing having oil groove, comprise cylinder-shaped body and graphite embedded hole, the cylindrical side of described cylinder-shaped body is evenly arranged the graphite embedded hole of multiple embedded graphite, inside and outside two side in the middle part of described cylinder-shaped body all circumferentially has horizontal oil groove, the inner side of described cylinder-shaped body circumferentially evenly has some and is vertically furnished with vertical oil groove, has oilhole the regioselectivity that this vertical oil groove is crossing with horizontal oil groove.
Supplement as to the one of technological scheme described in the utility model, the quantity of the graphite embedded hole between adjacent vertical oil groove is equal, ensure that the uniformity of graphite lubrication.
Supplement as to the one of technological scheme described in the utility model, described oilhole is evenly arranged and quantity is no less than 2, ensure that the oil groove that lubricant oil fully can enter into inner side surface lubricates.
First lubricant oil enter into the horizontal oil groove on cylinder-shaped body outer side wall, and then lubricant oil enters into the horizontal oil groove on madial wall along oilhole, flow to vertical oil groove along horizontal oil groove, thus makes the outboard sidewalls of steel bushing be obtained for sufficient lubrication.
beneficial effect
The utility model relates to a kind of injection machine selflubricating steel bushing having oil groove, and oil groove has been offered on the basis of graphite lubrication, and oil groove is distributed on outboard sidewalls, substantially increases lubrication effect, and wear-resisting property there has also been raising, operating lifetime.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model;
Fig. 2 is that master of the present utility model is depending on partly cuing open figure.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
As shown in Figure 1-2, mode of execution of the present utility model relates to a kind of injection machine selflubricating steel bushing having oil groove, comprise cylinder-shaped body 1 and graphite embedded hole 2, the cylindrical side of described cylinder-shaped body 1 is evenly arranged the graphite embedded hole 2 of multiple embedded graphite, inside and outside two side in the middle part of described cylinder-shaped body 1 all circumferentially has horizontal oil groove 5, the inner side of described cylinder-shaped body 1 circumferentially evenly has some and is vertically furnished with vertical oil groove 3, has oilhole 4 regioselectivity that this vertical oil groove 3 is crossing with horizontal oil groove 5.
The quantity of the graphite embedded hole 2 between adjacent vertical oil groove 3 is equal.
Described oilhole 4 is evenly arranged and quantity is no less than 2.
Embodiment
During use, steel bushing described in this practicality is socketed in the outside of piston rod, first lubricant oil enter into the horizontal oil groove 5 on cylinder-shaped body 1 outer side wall, then lubricant oil enters into the horizontal oil groove 5 on madial wall along oilhole 4, flow to vertical oil groove 3 along horizontal oil groove 5, thus make the outboard sidewalls of steel bushing be obtained for sufficient lubrication.
