Abstract
The utility model discloses a fastening conical sleeve for a roller ring of a high-speed wire rolling mill. An internal chamber of the fastening conical sleeve is an assembling through hole. The fastening conical sleeve is characterized in that the assembling through hole of the fastening conical sleeve is a stepped hole; one end of the stepped hole is a conical guide hole and the other end of the stepped hole is a waist-shaped hole; a tool withdrawal groove is arranged between the conical guide hole and the waist-shaped hole; and a uniform convex edge is arranged on the external wall at the waist-shaped hole end of the fastening conical sleeve. In the fastening conical sleeve, the fastening conical sleeve has a smart structural design and light weight; the roller ring can be quickly assembled, disassembled and replaced; during the usage process, the impact strength of a rolling part on a roller shaft is reduced, the stress concentration is reduced, and the service life of the roller ring and the roller shaft are also greatly prolonged.
Description
Technical field:
The utility model relates to the high-speed rod-rolling mill device, and concrete is a kind of fastening tapered sleeve of high-speed rod-rolling mill collars.
Background technology:
The locking mode that installs and fixes the mechanical gland-type of employing of the roll collar of rolling mill of high-speed wire rolling production line relies on the locking of the extrusion friction power realization collars between gland and collars at present.Because high speed wire rolling speed is high, description is many, and collars is changed very frequent, and is high to operating personnel's assembly technical requirement, if the improper meeting of coupling mechanism force causes collars to damage or lock is not tight, is prone to rolling accident.Present collars locking mode can not satisfy the requirement of above serviceability, and can produce threat to operator's personal safety.
The utility model content:
The utility model provides a kind of fastening tapered sleeve of high-speed rod-rolling mill collars, has solved defective of the prior art and deficiency, need not the frequent change collars, and greatly reduces so and possibility of accident occurrence.
The technical scheme of the utility model:
The fastening tapered sleeve of high-speed rod-rolling mill collars; The inner chamber of fastening tapered sleeve is an installation through holes, it is characterized in that: described fastening tapered sleeve installation through holes is a shoulder hole, and an end of shoulder hole is a conical pilot hole; The other end is a mounting hole, has escape between described conical pilot hole and the waist-shaped hole.
The fastening tapered sleeve of described high-speed rod-rolling mill collars is characterized in that: on the described fastening tapered sleeve waist-shaped hole end outer wall even flange is arranged.
Collars is connected through the described fastening tapered sleeve of the utility model with roll mandrel, and fastening tapered sleeve inner surface has identical cone angle with the roll mandrel outer surface, and collars locking is to be close to the interference of solid tapered sleeve inner cone and roll mandrel outer cone to assemble and realize.The transmission of roll-force, be close to solid tapered sleeve surfaces externally and internally respectively and the frictional force between the roll mandrel outer surface, collars inner surface realize.
The advantage of the utility model:
The clamping cone nested structure design of the utility model is ingenious, and fastening tapered sleeve is in light weight, can realize the Fast Installation and the dismounting and change of collars; In use also reduced the impact strength of rolled piece breaker roll axle, reduced stress and concentrate the service life of greatly improving collars and roll mandrel.
Description of drawings:
Fig. 1 is the axial arrangement sketch map of the utility model.
Fig. 2 is the radial structure sketch map of the utility model.
The specific embodiment:
The fastening tapered sleeve of high-speed rod-rolling mill collars; The inner chamber of fastening tapered sleeve is an installation through holes; Fastening tapered sleeve installation through holes is a shoulder hole, and an end of shoulder hole is a conical pilot hole 3, and the other end is a mounting hole 1; Have escape 2 between described conical pilot hole 3 and the waist-shaped hole 1, on the fastening tapered sleeve waist-shaped hole 1 end outer wall even flange 4 is arranged.
Fastening tapered sleeve is processed by high resiliency and toughness steel, and high resiliency guarantees that fastening tapered sleeve closely contacts comprehensively, and produces powerful moment of friction with collars, roll shaft; Toughness guarantees that clamping cone is enclosed within and presses people or drawing to go out Shi Buhui to produce plastic deformation, guarantee reusable, to improve utilization rate and stability.
Claims (2)
1. the fastening tapered sleeve of high-speed rod-rolling mill collars; The inner chamber of fastening tapered sleeve is an installation through holes, it is characterized in that: described fastening tapered sleeve installation through holes is a shoulder hole, and an end of shoulder hole is a conical pilot hole; The other end is a mounting hole, has escape between described conical pilot hole and the waist-shaped hole.
2. the fastening tapered sleeve of high-speed rod-rolling mill collars according to claim 1 is characterized in that: on the described fastening tapered sleeve waist-shaped hole end outer wall even flange is arranged.
