The utility model discloses simple structure, it is with low costs, convenient to use has improved the work efficiency that the support tile ground, has reduced intensity of labour, and the support tile atress is even, and the support tile curvature radius precision after the grinding is high, and then has guaranteed the grinding quality of roll.
Description
Technical field
The utility model is related to cold-rolling mill Roller Machining technical field more particularly to a kind of cold-rolling mill roll support watt grinding dresses
It sets.
Background technology
It before cold-rolling mill roll dressing, needs to hold in the palm it and watt is adjusted, keep roll axis parallel with lathe bed axis.It is right at present
A support watt surface is filled color by the adjustment of support watt generally using coloring polishing, roll is placed on the upper rotation of support watt
Afterwards, roll is sling, observation support watt surface state, support watt surface part is roll and support if there is not having coloured part then
Watt contact point, i.e., so-called contact high point belongs to point contact, and such point contact will produce vibration effect to roll dressing,
It when occurring contacting high point, needs high point carrying out scraping with scraper, then re-starts coloring, roll is placed into the upper rotation of support watt
After turning, roll is sling, observation support watt surface state carries out operation repeatedly, final to ensure that support watt realizes that face connects with axle journal
It touches.Existing support watt adjustment operation labor intensity is big, and the activity duration is long, and support watt adjustment is bothersome laborious.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of cold-rolling mill roll support watt grinding device.
Support watt adjustment operating efficiency is improved, keeps support watt adjustment time saving and energy saving.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of cold-rolling mill roll support watt grinding device, including grinding shaft and bearing；The grinding shaft is multidiameter structure, according to
Secondary to be made of spindle nose, axle journal, the shaft shoulder and axis tail, journal diameter is equal to roller diameter, and journal outer surface is evenly distributed with cutting edge, cuts
For sword with axis at 30~60 ° of angles, the distance between two cutting edges are 10~20mm；The axis tail is equipped with external screw thread, and bearing is set
Have therewith that compatible internal thread, grinding shaft are connected through a screw thread with bearing, bearing is clipped on the chuck of grinding machine.
The spindle nose is equipped with groove.
The bearing is cylinder structure.
Compared with prior art, the utility model has the beneficial effects that：
The utility model is simple in structure, at low cost, easy to use, is carried out to support watt by axle journal identical with roller diameter
Grinding improves the working efficiency of support watt grinding, reduces labor intensity, holds in the palm watt uniform force, the support watt curvature after grinding half
Diameter precision is high, and then ensure that the grinding quality of roll.

Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of cold-rolling mill roll support watt grinding device, including grinding shaft 1 and bearing 2.
Grinding shaft 1 is multidiameter structure, is made of successively spindle nose 2, axle journal 3, the shaft shoulder 4 and axis tail 5.Spindle nose 2 is equipped with recessed
Slot 10.3 diameter of axle journal is equal to roller diameter, and 3 outer surface of axle journal is evenly distributed with cutting edge 7, cutting edge 7 and axis angle at 45 °, and two are cut
It is 16mm to cut the distance between sword 7, i.e. cutting edge spacing 8 is equal to 16mm.
Axis tail 6 is equipped with external screw thread, and bearing 2 is cylinder structure, and bearing 2 is internally provided in compatible with 6 external screw thread of axis tail
Screw thread.Grinding shaft 1 is connected through a screw thread with bearing 2, and bearing 2 is clipped on the chuck 9 of grinding machine.Grinding shaft 1 passes through screw thread with bearing 2
Connection, grinding shaft 1 is replaced more convenient.Grinding shaft 1 is screwed into bearing 2 apart from big, and the utility model total length reduces, on the contrary then increase
Greatly.
As shown in Figure 1 and Figure 2, bearing 2 is clipped on the chuck 9 of grinding machine, and grinding machine drives grinding shaft 1 to rotate, right by axle journal 3
Support watt 11 is ground.When grinding support watt 11, oil-air lubrication, 1 rotating speed of grinding shaft is increase gradually to 30r/min by 10r/min, grinds
Time consuming is 5~7 minutes.
The utility model is simple in structure, at low cost, easy to use, improves the working efficiency of support watt grinding, reduces labor
Fatigue resistance holds in the palm watt uniform force, and the support watt radius of curvature precision after grinding is high, and then ensure that the grinding quality of roll.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its design is subject to equivalent substitution or change, should be covered within the scope of the utility model.
Method therefor is conventional method unless otherwise instructed in above-described embodiment.
