Abstract
The utility model discloses a prestressing force locking combination roll, it includes roll axle 1, and the cover has roll collar 2, roll axle 1's rear portion to be equipped with roll collar locking device on its characterized in that roll axle 1, the utility model has the advantages of bending deformation is little among the operating condition, long service life, and it is high to roll material size precision, and production efficiency is high, and is with low costs.
Description
The utility model relates to a kind of roll, especially a kind of prestressing force roll that is locked.
Present existing roll is a monolithic construction, and roll material is poor, and flexural deformation is big in the roll duty like this, service life is low, the stocking poor dimensional precision, and production efficiency is low, and overall structure can't fundamentally change material, if will change material, has then improved cost.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of combining structure is provided, in the duty flexural deformation little, long service life, stocking dimensional accuracy height, production efficiency height, the prestressing force that cost the is low roll that is locked.
The purpose of this utility model can reach by following measure: a kind of prestressing force roll that is locked, it comprises roll mandrel, it is characterized in that the rear portion that is with collars, roll mandrel on the roll mandrel is provided with the collars locking device.
Above-mentioned collars locking device can be for being with the retaining ring body on the roll mandrel, the retaining ring body is provided with hydraulic oil inlet, and the hydraulic oil inlet communicates with groove on the retaining ring body, and piston is embedded in the groove, the affixed locking nut in the rear portion of roll mandrel is connected with retaining ring on the locking nut.
Above-mentioned collars locking device can also be for being with the retaining ring body on the roll mandrel, be connected with retaining ring on the retaining ring body, the affixed locking nut in the rear portion of roll mandrel, locking nut are provided with the hydraulic oil inlet, hydraulic oil inlet communicates with groove on the locking nut, and piston is embedded in the groove.
The utility model has following good effect compared with the prior art: because the utility model is a split combination structure, roll mandrel presents pre-stressed state simultaneously, so flexural deformation is little, long service life, and stocking dimensional accuracy height, the production efficiency height, cost is low.
Below in conjunction with accompanying drawing preferred forms of the present utility model is elaborated:
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of the another kind of embodiment of the utility model;
Embodiment 1: a kind of prestressing force roll (referring to Fig. 1) that is locked, it comprises roll mandrel 1, be with collars 2 on the roll mandrel 1, collars 2 is made up of 9 collars, these 9 collars are made up of 4 carbide rings and 5 common steel central spacers, the rear portion of roll mandrel 1 is provided with the collars locking device, this collars locking device is to be with retaining ring body 6 on the roll mandrel 1, retaining ring body 6 is provided with hydraulic oil inlet 5, hydraulic oil inlet 5 communicates with groove on the retaining ring body 6, and piston 7 is embedded in the groove, and the rear portion of roll mandrel 1 connects a locking nut 4, be connected with retaining ring 3 on the locking nut 4, locking nut 4 is connected with retaining ring 3 wedge shapes.Screw locking nut 4, utilize the gap between many wedge shapes elimination retaining rings 3 of retaining ring 3 and locking nut 4 end faces and the hydraulic pressure ring body 6, connect high-pressure oil pipe, hydraulic oil more than the 250MPa is injected in the annular cylinder of piston 7 by hydraulic oil inlet 5, hydraulic oil promotes locking nut 4 by piston 7, through threaded function roll mandrel 1 is elongated, (roll mandrel elongates and is controlled in the regime of elastic deformation), utilize retaining ring 3 and many wedge shapes of locking nut 4 end faces fast the gap to be eliminated, remove roll mandrel produces behind the hydraulic oil elongation be locked ring 3 and locking nut 4 effectively the guarantor measure, collars 2 on the breaker roll axle produces clamping force, i.e. axial compressive force.
