Description
Technical field
This utility model is related to roll test equipment, particularly, is related to a kind of roll crown measurement apparatus.
Background technology
In the plate band production of steel industry and non-ferrous metal industry, roll is the one kind during plate rolling
Important part of appliance, it is the pressure that produced when rolling in opposite directions using a pair or one group of roll rolling stone roller Strip.Roll
Working condition directly affects the effect of Rolling Production.During rolling processing, due to factors such as temperature, abrasions, roll can
Be able to can deform, this deformation mainly includes the roll pars intermedia produced than axial two ends serious wear due to the middle part of roll
Position diameter is little, and the big situation of two-end part diameter (i.e. roll wear convexity) makes the axial profile curve of roll also change,
And then have impact on the effect of rolling of roll.For the quality for ensureing to process, after roll is before upper milling train and using a period of time
And inspection measured to roll crown (roll shape) is had to, therefore it is very heavy that roll is correctly detected whether to meet required precision
Want.Domestic to also have many producers at this stage using such as traditional measuring apparatus such as micrometer and saddle instrument, part is economical real
, then using external roll shape measuring instrument, instrument is huge, and cost is also high for the strong big business of power.
Chinese patent 201210408108.5 discloses a kind of roll profile measurement apparatus, and the program needs to be rolled according to tested
The different-diameter size of roller is designed and makes the measurement apparatus of different measuring scope, and versatility is not strong, is unfavorable for cost control；Separately
Outward, the program in measurement, lived by needs by the diameter envelope of whole roll, i.e., two support bar needs to keep 90 degree of angle
And while keep two support bars it is tangent with roll surface, therefore, the measurement apparatus measurement when need to take larger space, grasp
Make inconvenient, in addition, the program needs to remove roll from milling train in measurement, and roll radially opposite sides need to be cleared up when measuring
Space, enables two support bars while extending roll radially opposite sides, normally could measure, therefore, the program is not suitable for place
Inadequate situation and it is not suitable for the situation of in-site measurement, affects production efficiency.
With steel industry and and metallurgical technology continuous development, the measuring mechanism of roll is also correspondingly proposed higher
Requirement, in order to adapt to measure small volume, high precision, low cost, efficiency high, it is easy to operate, do not affect production etc. require,
Develop what a kind of new roller measure mechanism was a need for.
