Abstract
The utility model discloses a screw structure of a six-roller reversing mill. The screw structure of the six-roller reversing mill comprises a nut part and a bolt part. The nut part comprises a threaded rod and a threaded rod cap. A conical groove is formed in the front end of the threaded rod. The nut part comprises a nut provided with inner threads and a nut cap fixed at one end of the nut, a conical protrusion with the diameter slightly larger than that of the conical groove is arranged in the middle of the nut cap and the part, close to the nut cap, of the nut is provided with a conical cavity provided with internal threads. The length of the nut is similar to the length of the threaded rod. The threaded rod cap and the nut cap are the same in size. When a bolt is screwed into the nut, the conical protrusion arranged on the nut part enters the conical groove formed in the bolt part, and due to the fact that the diameter of the conical protrusion is larger than that of the conical groove, the bolt part is made to expand and accordingly the bolt and the nut are locked tightly. The threaded rod cap and the nut cap are the same in size so that the functions of a rivet can be achieved. Due to the fact that the part, close to the nut cap, of the nut is of a conical cavity structure and the conical structure is provided with the internal threads, further locking of the bolt and the nut is facilitated.
Description
Technical field
The utility model belongs to five metals field, particularly a kind of screw structural of six roll reversing rollers.
Background technique
Screw, also someone is its " screw " [Screw] (screw), " screw rod " (lead screw).Screw is common name in fact, and screw, lead screw are all distinguishing mutually.Screw is generally WOOD SCREWS; Be that front end is acuminous that, pitch is larger, is generally used for fastening ligneous piece, working of plastics.Lead screw is machine screw (MACHINE SCREWS), is that of front end tack, and pitch is less, evenly, is generally used for fastening metal, machine part.Rivet: in riveted joint, utilize self deformation or interference to connect by the part of riveting parts.Rivet kind is a lot, and informal.Conventional have cup head, tack, semitubular rivet, solid rivet, sunk head rivet, self-plugging rivet, a tubular-shank rivet, and these normally utilize self deformation to connect by riveting parts.Be generally less than the cold riveting of using of 8 millimeters, be greater than the rivet hot of using of this size.But also there is exception, such as the nameplate on three ring locks, utilize the magnitude of interference riveted joint of rivet and lock body opening.
Summary of the invention
Main purpose of the present utility model is to provide a kind of screw structural of six roll reversing rollers.
For achieving the above object, the technical solution of the utility model is: a kind of screw structural of six roll reversing rollers, comprises nut portion and bolt part; Bolt part is divided and is comprised screw rod and spiro rod cap, the front end of described screw rod has a cone-shaped groove, described nut portion comprises female nut and is fixed on the nut cap of nut one end, nut cap middle part has a diameter to be slightly larger than the conical projections of described cone-shaped groove, and nut is female cone shape cavity near the part of nut cap.
As optimization, the threaded length of the length of described nut approaches.Described spiro rod cap is identical with described nut cap size.
The utility model screw structural, at bolt, be screwed in the process of nut, the conical projections of nut portion setting enters the cone-shaped groove that bolt part is divided setting, because conical projections diameter is greater than cone-shaped groove, impels bolt demi-inflation, thereby makes screw bolt and nut locking.Spiro rod cap is identical with described nut cap size, can play the effect of rivet.Nut is the further locking that female cone shape cavity structure contributes to screw bolt and nut near the part of nut cap.
Accompanying drawing explanation
Fig. 1 is the utility model screw structural structural representation.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, this embodiment by the following technical solutions: a kind of screw structural of six roll reversing rollers, comprises nut portion and bolt part; Bolt part is divided and is comprised screw rod 1 and spiro rod cap 2, the front end of described screw rod 1 has a cone-shaped groove 3, described nut portion comprises female nut 4 and is fixed on the nut cap 5 of nut 4 one end, nut cap 5 middle parts have a diameter to be slightly larger than the conical projections 6 of described cone-shaped groove, and nut 4 is female cone shape cavity near the part of nut cap 5.Threaded 1 length of length of described nut 4 approaches.Described spiro rod cap 2 is identical with described nut cap 5 sizes.
The screw structural of a kind of six roll reversing rollers of the utility model, at bolt, be screwed in the process of nut, the conical projections of nut portion setting enters the cone-shaped groove that bolt part is divided setting, because conical projections diameter is greater than, impels bolt demi-inflation, thereby makes screw bolt and nut locking.Spiro rod cap is identical with described nut cap size, can play the effect that rivet is done.Nut is the further locking that female cone shape cavity structure contributes to screw bolt and nut near the part of nut cap, well avoided the absent-mindedness of six roll reversing rollers screws when work and the risk that causes.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
1. a screw structural for six roll reversing rollers, comprises nut portion and bolt part; Bolt part is divided and is comprised screw rod and spiro rod cap, the front end that it is characterized in that described screw rod has a cone-shaped groove, described nut portion comprises female nut and is fixed on the nut cap of nut one end, nut cap middle part has a diameter to be slightly larger than the conical projections of described cone-shaped groove, and nut is female cone shape cavity near the part of nut cap.
2. the screw structural of a kind of six roll reversing rollers according to claim 1, is characterized in that the threaded length of length of described nut approaches.
