Description

A kind of composite (back-up) roll for rolling wave type ripple composite plate
Technical field
The present invention relates to a kind of assembled roller equipment for rolling wave type ripple composite plate, belong to roll technology field, use In the roll of rolling wave type ripple complex plate strip.
Background technology
At present, the composite metal plate being made up of different performance is widely met the tendency of in metallurgy, mine, chemical industry, space flight etc. In industrial circle, metallic composite fully plays the respective advantage of group element material, and existing rolled metal composite plate blanks roll Control equipment, uses flat roll mill Rolling compund slab more, and the complex plate strip bond strength of flat roll mill rolling is low, easily tears Split;
Furthermore current roll device mainly has two kinds:One is in roll body surface face by modes such as casting, built-up welding, laser treatments Constitute certain thickness high-abrasive material, two is the relatively good shock resistance of roll, anti-shearing, bending resistance, and working lining is used Be high-abrasive material alloy collars, the two is fixed by certain mode, formed a composite (back-up) roll;Wherein, use Fixed form is different, and the production cycle can occur big change accordingly, easily ftracture for the complex plate strip for solving flat rolling, The shortcomings of combined efficiency is low, the production cycle is long, it is impossible to meet existing national product needs;Therefore, a kind of new rolling of design The rolling device of complex plate strip, the effective bond strength for improving composite metal plate, increases intermetallic adhesion, dismounting side Just, the excessive defect of stress concentration is effectively avoided, shortens processing and the assembly period of roll, farthest improve production effect Rate.
The content of the invention
It is an object of the invention to provide a kind of composite (back-up) roll for rolling wave type ripple composite plate, for rolling wave type ripple Complex plate strip, while be coupled effectively raising the concentricity that roll shaft covers with roller using rectangular spline, centering precision is high and steady It is qualitative good, axial roll shifting can be effectively prevented, corrugation rolls service life is improved, and be easy to assembly or disassembly.
To achieve the above object, it is of the invention it is a kind of roll wave type ripple composite plate composite (back-up) roll, it include roll shaft, Roller set, spline, flat key, locking back-up ring, screw, its architectural feature is roll shaft(1)On be provided with external splines(3), in roller puts and is provided with Spline, roller set(2)It is assemblied in roll shaft(1)On, by spline(3)Positioning, roller set(2)Outer surface be wave type ripple, ripple Height is compound plate thickness(0.1-1.5)Times, waviness width is wave height(3-20)Times, roll shaft one end passes through the shaft shoulder(4) Axial locking registration roller set, the other end of roller set passes through flat key(5), locking back-up ring(6)And screw(7)Cooperation realize roll shaft axle To, radial direction locking positioning.
Wherein, a kind of composite (back-up) roll of described rolling wave type ripple composite plate, it is characterised in that described wave type ripple Line is axial and continuously distributed on roller set surface parallel to roll.
Wherein, a kind of composite (back-up) roll of described rolling wave type ripple composite plate, it is characterised in that described roll shaft roller Axle(1)On be directly provided with external splines(3), external splines(3)It is rectangular spline, the number of teeth of spline is 6.
Wherein, a kind of composite (back-up) roll of described rolling wave type ripple composite plate, it is characterised in that described roll shaft(1) Shape wave spline(3)With the wave type roller set that inner surface is provided with inner spline groove(2)By slight interference amount elastic conjunction in roll shaft(1) On, realize that roll shaft is enclosed within circumference, radial direction locking positioning with roller.
Using roll structure device as described above, the present invention has superiority as described below:
1 can at utmost avoid dissimilar metal because of strip caused by elongation percentage difference using rolled metal corrugated plating of the present invention Sideslip problem, while increased the contact area of metal faying face, greatly improves the bond strength of composite metal plate, improves The recombination rate of composite plate;
2 can shorten Roller Machining and assembly period using the present invention, and rectangular spline processing is simple and convenient, with path centering, centering High precision;
3 can be used for the milling train high for centering precision, stability requirement, and large carrying capacity using the present invention, can be effective Avoid axial roll shifting phenomenon;
4 are coupled roll shaft and roller set using rectangular spline, can both realize that roll shaft was circumferentially positioned with what roller covered, effectively improve roller The concentricity of axle and roller set, centering precision is high and good stability, it is also possible to eliminate what heat treatment caused using the method for grinding Deformation, improves corrugation rolls service life, and roll shaft covers junction uniform force with roller, and roll can bear larger roll-force, And the centering that is covered with roller of roll shaft, guidance quality are good, are easy to assembly or disassembly.
