Description
Technical field
The utility model relates to a kind of quenching roller neck spreading structure.
Background technology
In quenching technology, the roll for roll neck length < 570mm needs spreading roll neck just can complete quenching.And the method for existing spreading roll neck mainly connects one section of roll neck with screw after roll end face beats threaded hole, the deficiency of the method is: need first car plain-barreled roll neck end face before beating threaded hole, tapping after setting-out punching, a general roll needs the M18 threaded hole processing 3 degree of depth about 20 ~ 30mm on boring machine, usually just need 3 hours, and postorder sectional fixture is also comparatively complicated.Therefore, waste time and energy, be not suitable for industrialized production.
Utility model content
The purpose of this utility model is to solve the problem, and provides a kind of quenching roller neck spreading structure.
The technical scheme realizing the utility model object is: a kind of quenching roller neck spreading structure, comprises and lengthen roll neck cover and back-up ring; The internal surface of described lengthening roll neck cover is provided with annular groove; The external diameter of described back-up ring and the diameter of described annular groove adapt; Internal diameter and the described quenching roller neck external diameter of described back-up ring adapt.
Described lengthening roll neck cover is made up of body and upper cover; Described body is made up of pullover and cover tail; Described pullover internal diameter is less than the internal diameter of described cover tail; Described pullover front portion is semi-circular tube, and rear portion is pipe; Described annular groove is located at described pullover front inner surface; The structure of described upper cover and described pullover front portion symmetry.
The positively effect that the utility model has: (1) spreading architecture of the present utility model is simple, easy for installation, greatly saves the time, also mitigates manpower simultaneously.(2) spreading structure of the present utility model only need process the back-up ring of corresponding internal diameter for the roll neck of different diameter, and use range is comparatively wide, and can Reusability.

Fig. 2 is the structural representation of lengthening roll neck of the present utility model cover upper cover.
Fig. 3 is the structural representation of lengthening roll neck of the present utility model cover.
Fig. 4 and Fig. 5 is that lengthening roll neck of the present utility model cover and back-up ring carry out the schematic diagram of spreading to quenching roller neck.
Embodiment
Quenching roller neck spreading structure of the present utility model comprises lengthening roll neck cover 1 and back-up ring 2.
See Fig. 1 ~ Fig. 3, lengthen roll neck cover 1 and be made up of body 11 and upper cover 12.Body 11 is made up of pullover 111 and cover tail 112.The internal diameter of pullover 111 is less than the internal diameter of cover tail 112.The front portion of pullover 111 is semi-circular tube, and rear portion is pipe.The front inner surface of pullover 111 is provided with annular groove 1-1.The structure of upper cover 12 and the front portion symmetry of pullover 111.
The external diameter of back-up ring 2 and the diameter of annular groove 1-1 adapt; The internal diameter of back-up ring 2 adapts with quenching roller neck 3 external diameter.The external diameter of the back-up ring 2 of the present embodiment is Φ 260(-0.5 ~-1) mm, width is 19mm.The diameter of annular groove 1-1 is Φ 260(0 ~+0.2) mm, width is 20mm.
See Fig. 4 and Fig. 5, spreading structure using method of the present utility model is as follows: first snap in back-up ring 2 by quenching roller neck 3, then back-up ring 2 is put into the annular groove 1-1 of body 11, finally upper cover 12 covered and be screwed.
