B, roller, spindle nose, which synchronize, is machined to size requirement；
C, roller surface quenches: roller surface quenching hardness is 92~97HSD, and depth of hardening zone is not less than 15mm；
D, the pilot hole boring of roller both ends is machined to fitted position, and grinding is to assembling ruler at the assembly outer circle of spindle nose
It is very little；
E, it assembles: using the cooling elastic conjunction mode of roller heating, spindle nose, spindle nose and roller being assembled into one；
F, be ground: using pouring water, filing is ground to final size to the roller periphery assembled；
G, dynamic balancing: dynamic balancing measurement is carried out to the above-mentioned hollow roll made, records unbalanced go in test
After weight is by calculating, duplicate removal is carried out when processing by keyseat on subsequent spindle nose.
Specifically, in step c, when quenching, quenching apparatus selects power frequency heat hardening lathe, and 250 ± 20Kw of initial power rises function
Rate speed 70Kw/30s balances 480 ± 20Kw of power, and 880~890 DEG C of heating temperature, the type of cooling is water cooling+depth after quenching
It is cold.
For convenience of the assembly of spindle nose and roller, in step e, when assembly, first finds out the position of centre of gravity of spindle nose and bored at this
Hole tapping, select cold-resistant stainless steel hanging ring screw for connect lift by crane, it is ensured that spindle nose sling after can it is straight smoothly push-in roller in
Hole is without catching phenomenon.
In step f, the grinding of pouring water axially is bored two along spindle nose and is made at 180 ° of through-hole in the processing of spindle head
To fill the water drainage hole, openings brill attacks sealing taper pipe thread, before grinding, the first water filling in roller, and after filling roller inner cavity 3/4,
Two through hole mouth is blocked with silk plug, is ground, and after being ground, then removes silk plug, drains road work after being carried out after the water of roller inner cavity again
Sequence.
The beneficial effects of the present invention are: hardness number with higher and deeper after the hollow roll quenching that the present invention makes
Quench-hardened case；Grinding efficiency can be improved using the method for grinding of pouring water, and guarantee the requirement of the high-precision geometric tolerance of roll, move flat
De-weight method after weighing apparatus test, simplifies technique；Wearability, the service life of product are higher than general papermaking hollow roller drum 4~5
Times, it is reused after carrying out multiple reconditioning in use process.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of hollow roll of the present invention.
In figure: 1. rollers, 2. spindle noses, 3. silk plugs, 4. through-holes
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
A kind of high rigidity papermaking hollow roll structural schematic diagram as shown in Fig. 1, including roller 1 and it is connected to roller 1
The spindle nose 2 at both ends opens up on one of spindle nose 2 there are two the through-hole 4 at 180 °, and 4 mouthfuls of ends of through-hole are connected with for sealing
Silk plug 3.
A kind of manufacture craft of high rigidity papermaking hollow roll has following steps:
A, it stocks up: getting roller 1,2 material of spindle nose ready, it is the structural alloy steel tube body of 55mm that in the middle of the roller 1, which selects wall thickness, this
Sample can prevent the permeability that biggish deformation and quenching occur in quenching, while mitigate this body weight of roll, it is ensured that high speed is revolved
The safety and stability changed a job when making.
B, roller 1, spindle nose 2, which synchronize, is machined to size requirement.
C, 1 surface hardening of roller: 1 surface hardening hardness of roller is 92~97HSD, and depth of hardening zone is not less than 15mm；It quenches
When fiery, quenching apparatus selects power frequency heat hardening lathe, and 250 ± 20Kw of initial power, power per liter speed 70Kw/30s balance power
480 ± 20Kw, 880~890 DEG C of heating temperature, the type of cooling is water cooling+deep cooling after quenching.
D, 1 both ends pilot hole boring of roller is machined to fitted position, and grinding is to assembling ruler at the assembly outer circle of spindle nose 2
It is very little.
E, it assembles: using the cooling elastic conjunction mode of the heating of roller 1, spindle nose 2, spindle nose 2 and roller 1 being assembled into one,
When assembly, since spindle nose 2 is concentric reducer, when lifting, is laid particular stress on, therefore first calculates and find out the position of centre of gravity of spindle nose 2 and bore at this
Hole tapping, select cold-resistant stainless steel hanging ring screw for connect lift by crane, it is ensured that spindle nose 2 sling after can it is straight smoothly push-in roller 1
Inner hole is without catching phenomenon.
F, be ground: using pouring water, filing is ground to final size to 1 periphery of roller assembled, mill of pouring water here
It cuts, in the processing of spindle head 2, attacks close as drainage hole, 4 mouthfuls of through-hole brills are filled the water at 180 ° of through-hole 4 along two, the axial brill of spindle nose 2
Taper pipe thread is sealed, before grinding, the first water filling in roller 1, after filling 1 inner cavity 3/4 of roller, 4 mouthfuls of two through hole are blocked with silk plug 3, into
Row grinding, after being ground, then removes silk plug 3, carries out later process again after draining 1 inner cavity water of roller.
G, dynamic balancing: dynamic balancing measurement is carried out to the above-mentioned hollow roll made, records unbalanced go in test
After weight is by calculating, duplicate removal is carried out when processing by keyseat on subsequent spindle nose 2, reduces the work of boring machine drilling duplicate removal
Sequence can be rapidly achieved the requirement for dynamic balance of product.
Hardness number with higher and deeper quench-hardened case after the hollow roll quenching that the present invention makes；1 inner hole of roller can
Deep-hole boring processing is carried out on the lathe of repacking, improved efficiency reduces cost；Grinding effect can be improved using the method for grinding of pouring water
Rate prevents 1 surface of roller to be deformed, ensure that the requirement of roll high-precision geometric tolerance, dynamic balancing measurement is by subsequent shaft
Duplicate removal is carried out when keyseat is processed on first 2, simplifies technique；Wearability, the service life of product are effectively improved, and are being used
It is reused after multiple reconditioning being carried out in the process.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
