Technical field
The utility model belongs to oblique milling technical field, relates to two roller slitless tube mills, is specifically related to a kind of roller for two-roller skew-rolling slitless tube mill apart from online dynamic micro-adjustments device.
Technical background
Hot rolled seamless steel tube production technology is the technology by operations such as heating of pipe blank, perforation, mill milling, sizing, alignings, solid pipe billet being processed into seamless steel pipe, tradition two roller slitless tube mills do not have roll spacing on-line tuning function, in the process of rolled steel tube, there will be the phenomenon that steel pipe head, tail wall thickness are overproof, cause crop, back-end crop length to increase the problem directly affecting the lumber recovery of steel pipe.
In order to solve the problems referred to above that prior art exists, the utility model have developed a kind of roller apart from online dynamic micro-adjustments device, and this device adopts mechan-amplifier principle to solve roll spacing and accurately controls a difficult problem online.
Summary of the invention
The utility model is low at longitudinal wall thickness accuracy after opening and subtracting machine in order to solve steel pipe, and crop end loses serious problem, and provides a kind of roller apart from online dynamic micro-adjustments device.This device adopts mechan-amplifier principle to solve roller apart from dynamically accurately controlling a difficult problem online.
The utility model is achieved through the following technical solutions:
A kind of roller, apart from online dynamic micro-adjustments device, comprises the slewing equipment be fixed in housing, spin friction is secondary and open oil cylinder soon; Described spin friction is secondary is that the rotating ring of helicoid and stationary ring form by end face; Described slewing equipment is rotated in housing by bearing, and rotating ring is fixed on the terminal surface of slewing equipment; Described oil cylinder of opening soon is fixed in housing can only be seesawed along axis by positive stop key, and stationary ring is fixed on to be opened on the cylinder barrel of oil cylinder soon, and wherein the end face of rotating ring and stationary ring is coaxially installed in opposite directions.
The end face 3-8 section of described rotating ring and stationary ring, specifically determine according to ring central diameter size and fine setting ultimate range, the relative rotation angle of helicoid regulating ring when number of fragments determines fine setting, every section is helicoid, arrange between helicoid and be free cutter spacing, lead angle tangent value equals the ratio of amount trimmed rotary distance relative in central diameter.
The described cylinder rod opening oil cylinder is soon built-in with displacement transducer.
When installing and using, the utility model can adopt an oil cylinder to drive the mode of two covering devices to install by connecting rod, and as shown in Figure 3, the mode that also set of device can be adopted to join an oil cylinder is installed, as shown in Figure 4.During installation, can be arranged on roll, also can be placed on frame, coordinate with balancing cylinder and adjust mill rolls apart from value, to be installed on roll-box, open oil cylinder masthead soon on frame, the balancing cylinder that roll-box is fixed in frame pulls, make to drive oil cylinder bar soon and contact gapless with frame mechanical planarization, installation diagram as shown in Figure 5,6.
The utility model is secondary and open oil cylinder soon by spin friction, realizes the object of on-line tuning roll spacing, and the effect first opened soon, as steel pipe rolling distance afterbody 50-100mm, is opened oil cylinder soon and opened fast steel pipe is passed through, prevent tail card accident from occurring; It two is drive cylinder action roll soon to open when roll-force exceedes setting value, and steel pipe stops rolling, and proterctive equipment is not impaired; And form spin friction pair employing mechan-amplifier principle solution roller apart from dynamically accurately controlling a difficult problem online by helicoid regulating ring.
The utility model roller distance on-line tuning is for four sections of helicoids, during initial position, a pair helicoid regulating ring is coaxially put in opposite directions, the height point of every section of helicoid and the low point gearing of helicoid corresponding with it, four sections of helicoids are tightly cut and are meshed together under roll-force effect; Rotating ring is fixed on slewing equipment end face by hexagon socket head cap screw and key, and slewing equipment is installed in housing and can only rotates and can not axial feed or return; Stationary ring is fixed on by hexagon socket head cap screw and key to be opened on cylinder tube soon, limited location key between cylinder tube and housing, can only feeding and returning in the axial direction, moves without spin; During work, as shown in Figure 3, slewing equipment driven rotary ring under the promotion driving oil cylinder circumferentially rotates to an angle α, make rotating ring and stationary ring that relative rotation occur, angle is α, and between two rings, axial distance increases s, s value and the proportional relation of anglec of rotation α; Due to rotating ring under thrust bearing effect without axial feed motion, stationary ring is pushed out the displacement of s distance vertically, and also just will open the displacement that s distance released by oil cylinder soon, this s value is the value of roller apart from online dynamic conditioning.
The utility model adopts mechan-amplifier principle to solve the control difficult problem of roller apart from online accurate adjustment, roller is generally between 0-1mm apart from adjusting range, Adjustment precision is 0.01mm, control accuracy requires high, stroke range is little, adopt hydraulic servo control system investment high, the unstable maintenance cost of system is high, requires high to operator.And this device adopts mechan-amplifier principle can by the fine setting distance s(0-1mm of roll) be enlarged into the Long Distances L driving oil cylinder, L value is generally 50 ~ 100 times of s value, and multiplication factor is usually by the helicoid parameter decision in spin friction pair.Conversely, the error of oil cylinder stroke is driven to be reduced by this device, being embodied in roller apart from online dynamically its alignment error upper is 0.001 ~ 0.02 times that drives oil cylinder stroke departure, such as oil cylinder stroke error is driven to be 2mm, being embodied in roller apart from upper error is 0.002 ~ 0.04mm, meet roller apart from online dynamic conditioning control accuracy, decrease the complexity controlling difficulty and system; Roller detects feedback in order to control to drive the stroke of oil cylinder apart from adjustment amount in real time by the displacement transducer put in the inner, drive simultaneously oil cylinder also inbuilt displacement sensor be used for detecting its stroke, detected value is fed back to control system and forms closed loop servo-control system.
The utility model adopts conventional hydraulic system and electric-control system, simplifies hydraulic pressure and control system, reduces the investment of equipment, improve equipment reliability of operation and simplicity.
