Description
Technical field
The utility model is related to metallurgical technology field more particularly to a kind of taper pins that roll change buggy uses.
Background technology
Roll is the tool for making metal (stocking) generate plastic deformation, is to determine that rolling mill efficiency and the important of mill bar quality disappear
Consume component.Roll is the important part on steel rolling mill's tandem mill, and the pressure that is generated when being rolled using a pair of or one group of roll is rolled
Steel are ground, it is in direct contact with rolling raw material will appear great abrasion, need to be replaced frequently.
Roll changing carriage is the equipment of the roll and spare roll of replacing tandem mill, and roll change buggy is put down by trolley main body frame, sidesway
Platform, withdrawing device are constituted.Trolley main frame is shaped steel welding structure, in milling train hydraulicblocking device used above and is connected to machine
Frame, the track being equipped between track and rack on trolley main frame are connected, so that roll moves.Sidesway platform welds for shaped steel
Structure, idler wheel band be equipped with anti-friction bearing, level be directed laterally to by roller, loading and unloading roller, intermediate calender rolls device be vertical bearing
Seat is oriented to, and motor driving, there is fixed limiter at both ends.Withdrawing device is the jaw type trolley (weldment) with idler wheel, is equipped with
Anti-friction bearing.By motor, gear and rack drives.The connection and disengagement of roller are acted on overhanging roll neck by electronic jaw and are completed,
To every set roller group, working roll and intermediate calender rolls hook can be opened and closed individually.
Currently, according to work roll cooling in different processes, the type of roll is various, and the roll changing carriage for carrying out roll replacement is also deposited
In multiple types.In coupled pickling and tandem mill, the operating condition of roll is the most complicated in milling train component, damages the frequency replaced
Rate highest.Therefore, mill roll is very important one of ongoing operations during Rolling production, and the quality of roll changing carriage is directly
The operating efficiency for influencing milling train, influences the operating efficiency of entire unit and the release of production capacity.
In coupled pickling and tandem mill, the roll change buggy of roll is arranged in milling train fore side, is moved forward and backward in milling train area, roll change
Trolley can be directly entered between roll when working, and a set of new roll is placed in front of each rack of milling train, is extracted out from rack old
Roller is inserted into new roller in rolling-mill housing after sidesway, completes roller replacing operation.In use, roll change buggy main frame is easy hair
Change shape, so that rolling-mill housing track step is occurred with roll change buggy main frame track generation dislocation or track seam, makes roll change
Operation cannot efficiently accomplish, and influence roll change rhythm, and then leverage operating efficiency.In addition, roll sinks during roll change
The shearing impact power that will produce, to impacting for roll change buggy；In the state of accident, rack inner orbit has not in position
It happens, is easy to cause and causes safety work accident.
Therefore, those skilled in the art is dedicated to developing a kind of taper pin that roll changing carriage uses, and improves existing roll changing carriage and exists
The defects of use.
Utility model content
In view of the drawbacks described above of the prior art, technical problem to be solved in the utility model is roll changing carriage main frame rail
Track seam crossing step phenomenon caused by road or the deformation of rolling-mill housing inner orbit.Prevent roller replacing operation from efficiently accomplishing.
To achieve the above object, the utility model provides a kind of taper pin, including taper pin main body and the tight stopper circle of taper pin；Its
In, the taper pin body front part is that section is circular cone, has chamfering in front end point；Taper pin back body section is just
It is rectangular.
Further, diameter is less than the rear portion square length of side at the front cone maximum gauge；
Further, the taper of the round centrum is 1:50；
Further, the tight stopper circle shape of the taper pin is square, and inside is circular cavity；
Further, include chamfering between the tight stopper circle inner circular cavity of the taper pin and outer square.
In the preferred embodiments of the present invention, the cone should be in the middle position of square；Cone length with just
Rectangular length is 1:1；
In another preferred embodiment of the utility model, the taper pin main body is installed on the downside of roll changing carriage main frame；Cone
It locks stopper circle correspondence and is installed on rolling-mill housing track corresponding position.
The beneficial effects of the utility model are：
One, by installing taper pin main body on roll change buggy main frame, installing taper pin locking on rolling-mill housing inner orbit
It is existing to effectively eliminate track seam crossing step caused by roll changing carriage main frame track or the deformation of rolling-mill housing inner orbit for baffle ring
As making roller replacing operation efficiently accomplish, promoting efficiency of the roll changing carriage when carrying out roll change operation；
Two, baffle ring is locked by installing taper pin on roll change buggy main frame, installing taper pin on rolling-mill housing inner orbit,
Roll during roll change can be effective against to sink the shearing impact power generated, accident is reduced simultaneously promoting roll change operating efficiency
Occurrence probability；
Three, baffle ring is locked by installing taper pin on roll change buggy main frame, installing taper pin on rolling-mill housing inner orbit,
Impact of the roll to roll changing carriage during roll change can be effectively reduced, the roll changing carriage service life is extended, has saved plant maintenance and dimension
Accomplish this；
Four, baffle ring is locked by installing taper pin on roll change buggy main frame, installing taper pin on rolling-mill housing inner orbit,
In the state of accident, if rack inner orbit position is displaced, roll changing carriage cannot be close to rack, to effectively avoid safety
The generation of accident；
In conclusion the taper pin of the utility model, eliminates roll changing carriage main frame track or rolling-mill housing inner orbit becomes
Track seam crossing step phenomenon, makes roller replacing operation efficiently accomplish caused by shape, promotes roll changing carriage when carrying out roll change operation
