Abstract
The invention discloses a composite roll which comprises a roll axle, a fastening cap and a roll sleeve. A step is arranged on the lower half section of the roll axle, the roll sleeve sleeves the roll axle, the lower end of the roll sleeve is arranged on the step, a compressing sleeve is mounted at the upper end of the roll sleeve, threads are arranged on the upper half section of the roll axle, the fastening cap is fittingly connected with the threads, and the compressing sleeve and the roll sleeve are fixedly connected with each other by the fastening cap. The composite roll has the advantages that the composite roll is simple in structure, easy to manufacture, low in cost and high in practicality, the rolling areas can be enlarged, local roll fixing pressures can be reduced, and the service life of the roll can be greatly prolonged; the roll sleeve can be detached and reused, and accordingly the construction cost can be lowered.
Description
Technical field
The present invention relates to a kind of metallurgical roller device, in particular, it is to be related to a kind of removable combined type ring rolloff
Forming device processed.
Background technology
The ring of tradition rolling adopts integral type roll, has disadvantages that it is impossible to enough solve quick-replaceable between different product
Problem, integral type roll in use, if crackle in roll, needs all to change, and different product rolls
Internal diameter processed is different, so needing a lot of customization rolls, high cost, long the production cycle, difficulty of processing are big.
Content of the invention
The present invention is directed to the deficiency of existing product, and provides a kind of structure simple, practical, safe and reliable, repeatable
A kind of composite roller using.
A kind of composite roller of the present invention, described roll includes roll axle center, fastening cap and roll sheath, described roll
Axle center lower semisection is provided with step, and described roll axle center is set with roll sheath, and described roll sheath lower end is placed on step, described
The upper end of roll sheath is provided with clamping sleeve, and described roll mandrel heart upper semisection is provided with and the screw thread fastening and cap matches, described
By fastening and cap is fixedly connected clamping sleeve with roll sheath.
The upper end in described roll axle center is provided with lifting nut.The upper end in described roll axle center is provided with lifting nut.Institute
State fastening and cap quantity is two, connected by latch between two fastenings cap.Described clamping sleeve is made up of seamless steel pipe.
The invention has the beneficial effects as follows: (1) structure is simply it is easy to manufacture, low cost；(2) practical, increase rolling surface
Long-pending, so that the local pressure of stationary roll is reduced, substantially increase the service life of roll；(3) roll sheath detachably reuses,
Reduce construction cost.
