A kind of novel 11 roller straightener roller system Zero calibration apparatus
Technical field
This utility model belongs to metallurgical technology field, is specifically related to a kind of novel 11 roller straightener roller system Zero calibration apparatus.
Background technology
Steel, in rolling, cooling procedure, due to the impact of various factors, usually can produce shape defect.In order to eliminate these defects, steel need to align on straightener.Aligning makes the crooked position of steel bear sizable back-flexing or stretching exactly, makes these parts produce certain plastic deformation, and after external force is removed, steel are replied through elastoplasticity, then reach straight.Therefore, the effect of straightener be by rolling, cooling procedure bends because of External Force Acting, variations in temperature or equipment that the steel of torsional deformation are corrected.
According to method for aligning and construction features, straightener can be divided into: gag straightener;Roll leveller;Pipe, bar straightener;Tension flattening machine;Stretching-bending straightener etc..For the aligning of hot rolled plate, need on roll leveller, sheet material to be aligned.Roll leveller principle is: sheet material by multiple staggered rollers, stands repeatedly alternating bending and aligned on roll leveller.The most multiplex is 11 roller straighteners.
Can wear and tear in the working roll of roll leveller surface in use for some time, in order to ensure the levelness of sheet material, do not affect leveling effect, be now accomplished by changing working roll, and make all working roller roll surface of upper roller system or lower roll system have same plane.And working roll is after replacing terminates, need the roll gap of straightener up-down rollers system is carried out school zero.
School zero of the prior art process has:
Roll gap is first closed into certain aperture by the first, then carries out the measurement of gap values between rollers with clearance gauge, to read the vertical dimension between up-down rollers system roll surface, so that it is determined that the zero-bit of up-down rollers system roll surface vertical dimension.Concrete, clearance gauge is generally adjusted to fixed thickness by operating personnel, it is placed in above the roll surface of lower roll system, again with hand steered firmly clearance gauge side, after range estimation clearance gauge is generally horizontal, carries out hand turning by four down screw rods being connected with upper roller system, thus crawl upper roller system carries out descending at slow speed in various degree in four orientation of horizontal plane, until the roll surface of up-down rollers system just contacts with clearance gauge upper and lower surface, i.e. it is believed that current clearance gauge thickness is exactly the gap values between rollers of up-down rollers system.But the process several operating personnels of needs in this school zero buttress many clearance gauges and measure simultaneously, or one clearance gauge of an operation librarian use carries out multi-faceted repetitive measurement, other operating personnel adjusts roll gap, and the levelness of clearance gauge, all it is dependent on visual observations, roll gap whether fit clearance gauge also be range estimation, whole operation process is affected the biggest by human users's custom and proficiency, the data that so may result in school zero certainly exist deviation not of uniform size, and the precision in this school zero is also closely bound up with the duty of straightener simultaneously.So, owing to school zero is forbidden, the roll gap that will result in straightener up-down rollers system is defective, and the levelness of upper roller system is also inadequate, directly affects the service life of working roll and the levelness of sheet material.
It two is symmetrically placed isometry block on the roll surface of lower roll system, lead is placed the most respectively on isometry block, pressure motor is utilized to be pressed on lead by upper roller system, take out lead after being raised by upper roller system again and measure data, respectively four down screw rods are carried out hand turning then according to the data measured, the lead the most more renewed re-start before operating procedure, until the roll gap school zero of up-down rollers system is accurate.But this school zero process needs repeatedly to press to take lead, certainly will cause and operation is repeated several times, and repeatedly calculate, not only cause and the measurement cost that more renew lead is used for multiple times, due also to manual measurement reading lead indentation data, there is bigger personal error, finally affect school zero and forbidden.
Owing to board mill rhythm of production is very fast, use both the above school zero process to make time in straightener whole roller system school zero 90-140 minute (more than repairing 60 minutes day), and there is the shortcoming of school zero low precision, thus production requirement can not be met.Additionally, the reason causing roller system of straightening machine school long when using separately during above two school zero also has, the main balance system of compensating cylinder thereon and the hydraulic die cushion system of down screw rod are shared a set of hydraulic system, when roller system school zero to the hydraulic die cushion system of down screw rod also release simultaneously during the main balance system release of compensating cylinder, but the hydraulic die cushion system of down screw rod need to be pressurising state during roller system school zero, if i.e. by jiggering after the hydraulic die cushion system release of down screw rod, arising that zero-bit is inaccurate after the pressurising of roller system.
In order to improve accuracy and the versatility in roller system of straightening machine school zero, reducing the time in roller system school zero, odd-job skill in straightener school is improved by spy, better meets the demand of production.
