Abstract
The utility model relates to the technical field of machines, in particular to a cylinder bottom nut of a tee joint extrusion cylinder. The cylinder bottom nut of the tee joint extrusion cylinder comprises a nut body, wherein the nut body is connected with a cylinder bottom of an oil cylinder, and the diameter of the outer surface of the nut body is 800 mm; the upper end, lower end, left end and right end of the outer surface of the nut body are respectively provided with a vertical inward hole; the front side edge and rear side edge of the outer surface of the nut body are respectively provided with a chamfer structure; a tooth form structure is arranged on the inner surface of the nut body, wherein the included angle between the upper tooth surface and lower tooth surface of the tooth form structure is 30 degrees; the front side edge and rear side edge of the inner surface of the nut body are respectively provided with another chamfer structure. Compared with the prior art, the internal surface structure and external surface structure of the nut are changed so that the nut can be used on the tee joint extrusion cylinder so as to improve the production efficiency of a t-branch pipe and the performance of a finished product.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of cylinder bottom nut of threeway extrusion oil cylinder.
Background technique
At present, in the three-way pipe course of working, generally first forge into rectangle, and then, by the manufacturing process of saw or mill, it is manufactured to needed shape.Such manufacture, not only manufacturing efficiency is low, and the end properties produced is poor.Now, for manufacturing efficiency and the end properties that improves three-way pipe, need design three-way valve mold and threeway extrusion oil cylinder, and the cylinder bottom nut is the requisite structure of threeway extrusion oil cylinder.Therefore, it is vital designing a kind of cylinder bottom nut that can be used in the threeway extrusion oil cylinder.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of cylinder bottom nut that can be used in the threeway extrusion oil cylinder is provided.
In order to achieve the above object, the utility model designs a kind of cylinder bottom nut of threeway extrusion oil cylinder, comprise the nut body, it is characterized in that: the nut body is connected with at the bottom of oil cylinder, the diameter of this external surface of nut is 800 millimeters, the upper end of this external surface of nut, lower end, left end and right-hand member respectively are provided with a vertical inside hole, the front and back dual-side of this external surface of nut is provided with chamfering structure, the internal surface of nut body is provided with tooth-shape structure, the addendum surface of tooth-shape structure and the angle between Dedendum surface are 30 °, the front and back dual-side of nut body internal surface is provided with another chamfering structure.
The angle of described chamfering structure is 45 °.
The angle of described another chamfering structure is 45 °.
The diameter in described hole is 50 millimeters.
Distance between the addendum surface center line of described tooth-shape structure and Dedendum surface center line is 16 millimeters.
The utility model compared with the existing technology, has changed the structure of the inner and outer surface of nut, makes nut can be used in the threeway extrusion oil cylinder, thereby improves manufacturing efficiency and the end properties of three-way pipe.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
The A place enlarged view that Fig. 3 is the utility model Fig. 2.
Referring to Fig. 1, Fig. 2 and Fig. 3,1 is the nut body; 2 is hole; 3 is tooth-shape structure.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model has designed a kind of cylinder bottom nut of threeway extrusion oil cylinder, comprises the nut body.Nut body 1 is connected with at the bottom of oil cylinder, the diameter of nut body 1 outer surface is 800 millimeters, upper end, lower end, left end and the right-hand member of nut body 1 outer surface respectively is provided with a vertical inside hole 2, the front and back dual-side of nut body 1 outer surface is provided with chamfering structure, the internal surface of nut body 1 is provided with tooth-shape structure 3, the addendum surface of tooth-shape structure 3 and the angle between Dedendum surface are 30 °, and the front and back dual-side of nut body 1 internal surface is provided with another chamfering structure.
In the utility model, the angle of chamfering structure is 45 °, and the angle of another chamfering structure is 45 °, and the diameter in hole 2 is 50 millimeters, and the distance between the addendum surface center line of tooth-shape structure 3 and Dedendum surface center line is 16 millimeters.
The utility model, when work, is connected nut body 1 with at the bottom of oil cylinder, by hole 2, will at the bottom of oil cylinder, fix.
The utility model has changed the structure of the inner and outer surface of nut, makes nut can be used in the threeway extrusion oil cylinder, thereby improves manufacturing efficiency and the end properties of three-way pipe.
