Abstract
The invention discloses a kind of oblique ripple composite (back-up) roll of rolled metal composite plate, including roll shaft, oblique ripple roller set, wedge key, retainer and hydraulic locking nut, it is characterised in that roller set outer surface is machined with oblique ripple, and oblique ripple is with the axial angle of roll（10‑80）O, wave height is compound plate thickness（0.1‑1.5）Times, waviness width is wave height（3‑20）Times, roller is sleeved on the outside of roll shaft, and circumference and unidirectional axially position that roller covers are realized by wedge key, and by shaft shoulder axial restraint roller set, the other end passes through hydraulic locking nut axial locking fixing roller set for one end of roll shaft.Composite (back-up) roll fastening precision of the invention is improved, it is engaged with roll shaft keyway using the lower work face and side of wedge key, realize that roll shaft axially loaded is uniform, avoid axial roll shifting, oblique ripple metal clad plate strip is rolled using composite (back-up) roll of the invention, the bond strength of complex plate strip can be improved, residual stress and angularity is reduced.
Description
Technical field
The invention belongs to roll technology field, a kind of oblique ripple composite (back-up) roll of rolled metal composite plate is disclosed, used
In rolled metal composite plate.
Background technology
At present, the composite plate being made up of the metal of different properties is met the tendency of in metallurgy, mine, chemical industry, space flight etc. extensively
In industrial circle, metallic composite fully plays the respective advantage of group element material, and existing rolled metal is compound to be relied primarily on
Rolling mill is realized, and roll is the strength member on rolling mill, produced pressure when being rolled using a pair or one group of roll
Metal composite plate blank material is ground to roll, great torque can be now produced, when torque overload causes roll shaft and roller set generation micro
Relative rotation, easily make roll shaft or roller set deform even damage or be broken, cause roll shaft or roller set short life, increased
Roll change frequency, it is impossible to meet existing national product demand；Therefore, a kind of combined type of new Rolling compund strip blank material of design
Roll, therefore, a kind of rolling device of new Rolling compund strip blank material of design, the effective combination for improving composite metal plate
Intensity, increases intermetallic adhesion, reduces the residual stress of composite metal plate, and convenient disassembly, shortens the processing of roll
With assembly period, maximum improve production efficiency.
The content of the invention
To achieve the above object, the present invention disclose it is a kind of rolling oblique ripple metal composite (back-up) roll structure, including roll shaft,
Roller set, wedge key, retainer and hydraulic locking nut.It is characterized in that roller set（1）Outer surface is machined with oblique ripple, oblique ripple and roll
Axial angle be（10-80）O, wave height is compound plate thickness（0.1-1.5）Times, waviness width is wave height（3-
20）Times, roller set（1）Inner surface is provided with keyway, roller set（1）It is sleeved on roll shaft（2）Outside, by wedge key（3）Positioning, roll shaft（2）
One end have the step shaft shoulder（4）Axial restraint roller set（1）, roll shaft（2）The other end have hydraulic locking nut（5）Axial locking
Fixing roller set（1）.
Wherein, a kind of oblique ripple composite (back-up) roll of rolled metal composite plate, it is characterised in that the wedge key（3）For general
Logical wedge key wedge key gradient is 1:100.
Technique effect
The purpose of the present invention, in that one kind is provided and is fixed on oblique ripple roller set using hydraulic locking nut axial grip mode
Assembled roller equipment on roll mandrel, while be coupled using wedge key effectively avoiding because there is shock and vibration in the operation of rolling
Larger torque when, keep roll shaft and roller to cover the reliability being connected, improve corrugation rolls service life, and be easy to assemble and tear open
Unload.Using the composite (back-up) roll of present invention rolling oblique ripple metal plate and belt, torque is transmitted by the wedge action of key, list can be born
To axial load, axial restraint effect is played to roll, prevent roll shifting, roll working life can be improved, shorten the processing of roll
With assembly period.Corrugation rolls set uses suitable wave numerics, so as to obtain rolling the compound sheet roll of oblique ripple faying face, changes
The bond strength and template of kind composite plate.
Brief description of the drawings
Fig. 1 is oblique ripple roller set, roll shaft, wedge key, the three-dimensional assembly schematic diagram of hydraulic locking nut；Fig. 2 is oblique ripple
Composite (back-up) roll three-dimensional assembly wedge key schematic diagram；In figure：1-roller set；2-roll shaft；3-wedge key；4-shaft shoulder；5-hydraulic lock
Tight nut.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the invention is described in further detail, it is real below
Example is applied for illustrating the present invention, but is not limited to the present invention.
As shown in Figure 1, 2, the composite (back-up) roll of rolling oblique ripple composite metal plate is planted, the roll is by roll shaft（1）, oblique ripple
Roller set（2）, wedge key（3）, hydraulic locking nut（5）Constitute, roll shaft（1）, wedge key（3）And hydraulic locking nut（5）Material be
No. 45 steel, oblique ripple roller set（2）Material is high strength cemented carbide steel 60GrMnMo, and oblique ripple is 20 with the axial angle of roll
O, wave height is 1.3 times of compound plate thickness, and waviness width is 12 times of wave height, and its architectural feature is roller set（1）Coaxially
The heart is sleeved on roll shaft（2）Outside, roll shaft（2）Outer surface keyway is provided with the gradient being engaged with wedge key, by wedge key（3）Realize
The circumferential and axial fastening positioning of roller set, wedge key（3）Fit tolerance with keyway selects P7/h6；Roll shaft（2）One end have step
The shape shaft shoulder（4）Axial restraint roller set, roll shaft（2）The other end have hydraulic locking nut（5）, pass through by super-pressure Hand oil pump
Ultrahigh pressure armored flexible pipe injects high-voltage oil liquid to hydraulic nut plunger shaft, promotes piston to stretch out, and roll shaft tension is produced pretightning force,
After required load is reached in roll shaft elastic range, then by retainer rotation come to oil cylinder end face after tighten, then unload, realize roller set
（1）In roll shaft（2）The axial locking of the other end is fixed, and hydraulic locking nut is connected through a screw thread with roll shaft.
