The nut for the friction screw press is characterized in that the nut comprises a cylindrical body, a screw hole is formed in the axial center of the body, threads are formed in the inner wall of the screw hole, an annular positioning step which is placed on a hole opening of the screw hole is arranged at one end of the body, the other end of the body is provided with a screw cap, an annular groove is formed in the side portion of the body, and at least one oil inlet hole which is communicated with the screw hole is formed in the bottom of the annular groove. The nut for the friction screw press has the advantages of being more reasonable in design, simpler in structure, capable of lowering the friction coefficient, not prone to rusting and easy to install and position, and conforming to the development tendency of the current social technology.
Description
Technical field
The utility model belongs to the friction screw press technical field, especially relates to a kind of friction screw press nut.
Background technique
Friction screw press is a kind of screw press that adopts friction driving way, claims again double disk friction screw press, and it utilizes the Contact Transmission of flywheel and friction disk the press machine productive group in metal forging workshop, and by the relative motion principle of screw rod and nut and work.Due to it, versatility is larger in the use, and the simple and cheap advantage of structure, installation, manipulation and supplementary equipment is arranged, therefore press workshop, forge shop and the stamping room in the industry such as machine-building, automobile, tractor and aviation all extensively adopts, and also can carry out stamping-out.Friction screw press is again building material machinery, is widely used in the dry-pressing formed production of ceramic tile, potlery tile, fire resistive material product.Friction screw press, since producing, has played important function in industrial development.But because its energy loss in the process of kinetic energy transmission is large, the parts rapid wear large, inefficiency, labor strength be large, can not meet the industrial production needs of New Times far away.Have more nut in friction screw press, it has the effect of locking, and in order to extend the working life of nut, for this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of Full automatic friction press [application number: 02241323.5], relates to a kind of integral crossbeam, support and controls Self-pressurizing agri mechanism, braking brake assembly mechanism, operating device, operation mechanism, charging mechanism, holder mould liftout mechanism etc. and form full-automatic process by the computerized control system commander that programmes.It is characterized in that: its crossbeam, support, column, column screw rod are with the fixing formation of temperature difference mode integral-rack; In addition, Chinese patent literature discloses a kind of Novel screw press main helix pair nut [application number: 200820020738.4], and described nut is consisted of Cuprum alloy inner core and box hat overcoat.Adopt box hat overcoat and Cuprum alloy core arrangement form, both met the requirement of nut wear resistance, greatly reduced again the materials of alloy, at least reduced the materials amount of 30% alloy, reduced cost.Above-mentioned several schemes have extended to a certain extent the working life of nut and reduced cost of production, but also at least have following defect: the easy corrosion of nut causes normally dismantling and installing, and, be difficult for nut is lubricated, in addition, be difficult for location, use and have narrow limitation.
The model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of nut that can make to be difficult for getting rusty and being easy to the friction screw press nut of locating.
For achieving the above object, the utility model has adopted following technical proposal: this friction screw press nut, it is characterized in that, this nut comprises cylindrical body, in the axial centre of body, is provided with screw, at the screw inwall, is provided with screw thread, be provided with the circular orientation step that is positioned at place, screw aperture at body one end, the other end is provided with stubborn cap, at the body sidepiece, is provided with circular groove, at the bottom land of circular groove, is provided with the oil inlet hole that at least one is communicated with described screw.Obviously, the utility model design is more reasonable, and structure is simpler, can reduce friction factor, makes nut be difficult for getting rusty, and in addition, is easy to install and location, meets the development trend of current social technology.
In above-mentioned friction screw press nut, described body sidepiece also is provided with some equally distributed arc convex.
In above-mentioned friction screw press nut, the height of described arc convex is 1～3mm.This height can be set according to actual requirement.
In above-mentioned friction screw press nut, described body is provided with near an end of circular orientation step the blind hole that some even circumferentials distribute.
In above-mentioned friction screw press nut, described blind hole depth is less than the height of circular orientation step.
In above-mentioned friction screw press nut, described stubborn cap is Hexagon.
Compared with prior art, the advantage of this friction screw press nut is: it is more reasonable to design, and structure is simpler, can reduce friction factor, makes nut be difficult for getting rusty, and in addition, is easy to install and location, meets the development trend of current social technology.
The accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides.
In figure, body 1, screw 11, circular orientation step 12, circular groove 13, oil inlet hole 14, blind hole 15, stubborn cap 2, arc convex 3.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, this friction screw press nut comprises cylindrical body 1, axial centre at body 1 is provided with screw 11, be provided with screw thread at screw 11 inwalls, be provided with the circular orientation step 12 that is positioned at screw 11 places, aperture at body 1 one ends, the other end is provided with twists cap 2, and this stubborn cap 2 is Hexagon, be provided with circular groove 13 at body 1 sidepiece, at the bottom land of circular groove 13, be provided with the oil inlet hole 14 that at least one is communicated with described screw 11.The present embodiment design is more reasonable, and structure is simpler, can reduce friction factor, makes nut be difficult for getting rusty, and in addition, is easy to install and location, meets the development trend of current social technology.
Specifically, in order to prevent skidding, at body 1 sidepiece, also be provided with some equally distributed arc convex 3.Optimized project, the height of the arc convex 3 here is 1～3mm.
In addition, be provided with the blind hole 15 of some even circumferentials distributions near an end of circular orientation step 12 at body 1.These blind hole 15 degree of depth are less than the height of circular orientation step 12.
As the present embodiment optimization scheme, the height of arc convex 3 is 2mm.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more been used body 1, screw 11, circular orientation step 12, circular groove 13, oil inlet hole 14, blind hole 15, twisted the terms such as cap 2, arc convex 3, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
