Description
Technical field
This utility model is related to steel industry steel rolling field, more particularly, to a kind of for improving what TMCP process conditions nipped
Roll notches device.
Background technology
Implement grooveless rolling in high line workshop, Bars Workshop, because the continuous casting billet length of side reaches 165mm, rolled piece nips into
For difficult point；The method being nipped by increasing angle of friction improvement has three kinds：Roller surface built-up welding, roller surface grinder buffing, roll
Surface indentation；What production scene was commonly used is first two, but：Roller surface built-up welding can affect product quality, and grinder buffing can increase
The big amount of labour and effect is bad；Application Design rational roll notches process and scratching device, even if width of nick is less
In the case of, it can improve and nips, and nor affect on product quality；Exactly due to lacking roll notches device reasonable in design,
The practical application that roller surface indentation at home and abroad improves in steel rolling bite condition is made to be in blank；Look into domestic and foreign literature, only
Record roll notches can improve rolled piece and nip, and have no the specific roll notches device of record.
Utility model content
Arrange that milling train produces nipping of grooveless rolling to solve big cross section continuous casting billet and the big spacing of the non-de- head of continual rolling
Problem, this utility model provides the scratching device that a kind of TMCP process conditions bottom roll nips, and this scratching device is not affecting
Solve big cross section continuous casting billet production grooveless rolling on the premise of product surface quality nips problem.
This utility model be employed technical scheme comprise that：
The scratching device that a kind of TMCP process conditions bottom roll nips, including chuck, gear, connecting rod, universal drive shaft, convex
Wheel, knife rest, cutter；On lathe chuck, gear is installed, so that gear centre line is overlapped with the lathe centre of gyration, gear includes gear
I and gear II, connecting rod is set at the central through hole of gear II, connecting rod in gear II vertically slidably, connecting rod
One end setting universal drive shaft, with universal drive shaft close vicinity arrange cam, connecting rod is passed to by the rotation of II lathe spindle of gear,
Again cam is passed to by universal drive shaft, cutter is abutted against on cam all the time by spring, Cutting tool installation manner on lathe saddle, cam and
Knife rest is fixed on lathe big palette.
Preferably, gear I is identical with gear II modulus, and the gear ratio of gear I and gear II is 81.
Preferably, cam is provided with 8 arc grooves being distributed uniformly and circumferentially.
Preferably, gear II center is flat through hole, and connecting rod is flat bar.
The beneficial effects of the utility model are：
This utility model effectively improves rolled piece and nips effect, in the case of not affecting product quality, solves big cross section
Continuous casting billet and the big spacing of the non-de- head of continual rolling arrange that what milling train produced grooveless rolling nips problem so that allowing nip angle to increase
2 °～4 ° it is achieved that the rationalization of roller surface indentation and standardization, standardization processing are it is achieved that roller surface indentation is improving
Roll nips the industrial applications of effect aspect.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain this practicality
New, it is not used to limit this utility model.
Below in conjunction with the accompanying drawings and specific embodiment is further described to application principle of the present utility model.
Embodiment 1
The scratching device nipping as Fig. 1-2, a kind of TMCP process conditions bottom roll, including chuck 1, gear, connecting rod 4,
Universal drive shaft 5, cam 6, knife rest 9, cutter 7；On lathe chuck 1, gear is installed, makes gear centre line and lathe centre of gyration weight
Close, gear includes gear I and gear II, at the central through hole of gear II, connecting rod 4 is set, connecting rod 4 is in gear II along axle
To slidably, one end of connecting rod 4 arranges universal drive shaft 5, arranges cam 6 with universal drive shaft 5 close vicinity, by II lathe of gear
Connecting rod 4 is passed in the rotation of main shaft, then passes to cam 6 by universal drive shaft 5, and cutter 7 abuts against on cam 6 by spring all the time,
Cutter 7 is arranged on lathe saddle 9, and cam 6 and knife rest 9 are fixed on lathe big palette.
Preferably, gear I is identical with gear II modulus, and the gear ratio of gear I and gear II is 81, so, chuck 1 or
Roll turns around, and cam turns 8 circles.
Preferably, cam 6 is provided with 8 arc grooves being distributed uniformly and circumferentially 12, such roll every revolution,
Cutter radially back and forth movement 64 times.
Preferably, gear II 3 center is flat through hole, and connecting rod 4 is flat bar.
During processing roll 10, start lathe, cutter 7 radially back and forth movement, by adjusting the radial direction of cutter 7 and roll 10
Distance, makes cutter 7 point of a knife contact with roll 10, and then radial feed makes cutting depth reach drawing requirement, in the course of processing
In, when cutter 7 is cylindrical with cam 6 contact when, cutter 7 cuts to roll 10, and works as the arc groove of cutter 7 and cam 6
When contacting at 12, cutter 7 does not cut to roll 10, then hangs up longitudinal self-acting feed, gets on the bus in roll 10 body surface
Go out horizontal trace and vertical trace, roll 10 rotary motion, cutter radial back and forth movement, long feed motion are carried out simultaneously；By the method,
Can process on roll is cylindrical be axially uniformly distributed along roll, the vertical trace of lead angle and the horizontal trace in 64 roads parallel to axis.
