Further to illustrate that the utility model is to reach the technological means and effect that predetermined purpose of utility model is taken,
Below in conjunction with attached drawing and preferred embodiment, to the composite rolling mill inclined wedge compensation system of the present utility model application and the tool of composite rolling mill
Body embodiment, structure, feature and its effect are described in detail.In the following description, different " embodiment " or " implementation
What example " referred to is not necessarily the same embodiment.In addition, the special characteristic, structure or feature in one or more embodiments can be by any
Suitable form combines.
As shown in Figure 1, Figure 2 and Figure 3, the utility model embodiment provides a kind of composite rolling mill inclined wedge compensation system, packet
Include Cam device comprising dynamic inclined wedge 1；Driving device 2 is connect with dynamic inclined wedge 1, for driving dynamic inclined wedge 1 to move；Displacement passes
Sensor 3 is set on dynamic inclined wedge 1, the shift value for measuring the movement of dynamic inclined wedge 1；Control unit 4 is passed with displacement respectively
Sensor 3 and driving device 2 are electrically connected, and control unit 4 can be used for the initial roller diameter according to roll and practical roller diameter, calculate roll
Required target compensation amount calculates further according to the angle of inclination of target compensation amount and dynamic inclined wedge 1 and moves the target that inclined wedge 1 should move

The dynamic inclined wedge 1 stated moves.Wherein, the programmable logic controller (PLC) of model SIEMENS PLC 400 may be used in control unit 4
It realizes, concrete model is Siemens cpu416-2DP.
The present embodiment is specifically described below by the principle of composite rolling mill inclined wedge compensation system.Mesh needed for roll
Mark compensation rate can by the work of the roller diameter decrement of the roller diameter decrement and top working roll of the upper backup roll of half times and
It obtains, wherein the initial roller diameter and practical roller diameter that the roller diameter decrement of upper backup roll and top working roll respectively can be by the two
It is obtained as difference；Displacement of targets amount can be worth to by the tangent at 1 angle of inclination of target compensation amount divided by dynamic inclined wedge, the target position
Shifting amount is so that the downward adjustment amount of dynamic 1 lower surface of inclined wedge reaches target compensation amount and the displacement that should move.Since displacement passes
Sensor 3 is arranged on dynamic inclined wedge 1, to measure the shift value of dynamic inclined wedge 1, therefore, when the displacement measured by the displacement sensor 3
When value is equal to the displacement of targets amount, you can illustrate that the downward adjustment amount of dynamic 1 lower surface of inclined wedge reaches requirement, roll line is in absolute altitude
Position.
It should be noted that being not on for the milling train of zero-bit for the initial position for moving inclined wedge 1, inclined wedge is being carried out
Before compensation, must into the zero-bit positioning (this process only executes in the debugging stage primary) of action inclined wedge 1, so as to for upper backup roll or on
The replacement of working roll provides reference position, wherein when zero-bit refers to that upper backup roll and top working roll are initial roller diameter, moves oblique
The location of wedge 1.Specifically, the step of positioning inclined wedge zero-bit can be：First zero is in inclined wedge 1 is set out by designer
The shift value that it should be moved when position, starts to move it is then possible to manually control dynamic inclined wedge 1, is used in combination ruler to measure and moves the movement of inclined wedge 1
Distance, until the distance value be equal to designer provide shift value when, manually control dynamic inclined wedge 1 stop movement, this position
The zero-bit of inclined wedge 1 is as moved, and the shift value measured by the displacement sensor 3 that control unit 4 is recorded at this time is dynamic inclined wedge 1
A reference value when in zero-bit.Importantly, for such situation, the shift value etc. above-mentioned worked as measured by displacement sensor 3
When displacement of targets amount, control unit 4 controls the driving device the 2 stoppings driving dynamic inclined wedge 1 and moves, that is, becomes passing when displacement
When shift value measured by sensor 3 is equal to the sum of displacement of targets amount and 1 zero reference value of dynamic inclined wedge, the control driving of control unit 4
Device 2 stops the driving dynamic inclined wedge 1 and moves.
The composite rolling mill inclined wedge compensation system that the utility model embodiment provides, by displacement sensor and connected to it
