Description
Technical field
The utility model relates to the cross roll straightener bite adjusting device of one of finishing equipment in the metallurgical machinery, especially can be implemented in the dynamic adjustment of roll gap in the aligning process and the detection of dynamic of load.
Background technology
At present, the roll gap of cross-roll straightening machine need be according to the diameter of aligning stocking, adopts with motor or manually be motive mode, drives the rotation of leading screw by decelerator, utilizes the change of relative position between leading screw and the nut to reach the size of adjustment gap values between rollers.This adjustment mode can't realize the adjustment of rolled piece roll gap in the aligning process, and reaches the best long adjustment time of gap values between rollers needs.For detecting in real time continuously of dynamic straightening force, at present domestic also do not have, and only is when particular state, short time installing force sensor between the stressed part of machine comes image data, have only the valid data of minute quantity, practicality is relatively poor, can't be to the technological improvement and the adjustment parameter of plant equipment.
Summary of the invention
The deficiency of the utility model in order to overcome and to solve the problems of the technologies described above, a kind of bite servo adjusting device is provided, the roll gap adjusting device of the existing cross-roll straightening machine of solution that can be convenient and reliable can not dynamically be adjusted roll gap under load condition, detect the problem of dynamic straightening force in real time.
Be the deficiency that solves the problems of the technologies described above, the technical scheme that the utility model adopted is, use a hydraulic pressure to adjust valve group and a bite servo adjusting device that is provided with the non-standard servo-cylinder composition of displacement transducer, alternative being installed on the aligning frame constituted the mechanical type roll-separating mechanism by motor reducer, leading screw and nut, and it includes roll gap control circuit, servo valve controller, servo valve, oil pressure sensor, bite servo adjustment oil cylinder, oil cylinder plunger displacement sensor composition.Displacement by HYDRAULIC CONTROL SYSTEM oil cylinder plunger and be arranged on the detected oil pressure of oil pressure sensor on the hydraulic circuit can realize easily that the band of roll gap carries dynamic adjustment and the dynamically real-time detection of straightening force, reaches to shorten roll gap and adjust the time.
The utility model, can align in the process of stocking at cross-roll straightening machine, adopt the control mode of automatic or manual, adjust roll gap and meet the requirements of the flattening precision requirement, detected dynamic straightening force can be used for instructing in real time adjusts parameter and plant maintenance, and has practical function for improving technological parameter.

The specific embodiment
As shown in Figure 1, cross-roll straightening machine is when adjusting the roll gap of smoothing roll, in the electric control system after sending the order (i) that roll gap changes, roll gap control circuit (1) among the PLC is after receiving roll gap adjustment instruction (i), to instruct amplification rear drive servo valve (3) to move by servo valve control amplifier (2), the pressure oil of hydraulic system enters (or outflow) bite servo by P mouth (or T mouth) through servo valve (3) and adjusts oil cylinder (5), the plunger displacement amount of this oil cylinder detects and feeds back in the roll gap control circuit (1) by the displacement transducer (6) that links together with the oil cylinder plunger, after comparing with the roll gap adjustment of being received instruction (1), reach the displacement accuracy of default when the difference that is compared after, roll gap control circuit (1) sends the instruction that oil cylinder stops to move, servo valve (3) cuts out, and the piston of bite servo adjustment oil cylinder (5) is fixed on the position of setting.
The oil pressure of hydraulic system is to determine that according to the load of maximum therefore servo adjustment oil cylinder (5) has enough abilities piston is moved when having the situation of load, thereby finishes the roll gap adjustment in the aligning process.Because the fast dynamic response time ratio motor of oil cylinder when loading is moving is fast, and can may not produce gummed as the motion in the mechanical transmission mechanism.Therefore, the adjustment precision of the mechanical transmission mechanism formed by motor reducer of the adjustment ratio of precision of servo adjustment oil cylinder want high and speed fast.
Oil pressure sensor (4) is connected servo valve (3) and bite servo and adjusts on the hydraulic circuit between the oil cylinder (5), and after the position that this bite servo is adjusted oil cylinder (5) reached requirement and asks, servo valve (3) cut out.Therefore, the pressure that is made of airtight oil pocket servo valve (3) and bite servo adjustment oil cylinder (5) is exactly the pressure that load produces, and by the detected oil pressure value of oil pressure sensor (4), can determine actual straightening force.
As shown in Figure 2, one end of servoBcylinder plunger (10) stretches out oil cylinder by oil cylinder plunger guide ring (11), the other end is in cylinder body, hollow-core construction is adopted on top at the oil cylinder plunger, be in order to improve the dynamic response performance of plunger, under the condition of proof strength and rigidity, to reduce the quality of plunger as far as possible.On guide ring (11) and servoBcylinder cylinder cap (8), sealing ring and guidance tape are installed.
Cylinder body structure of the present utility model is for dividing body structure.Be applicable to large-scale bite servo adjustment oil cylinder.Quality and the reduction manufacturing cost of large-scale oil cylinder for guaranteeing cylinder body, bite servo is adjusted the branch body structure that oil cylinder (5) can adopt servoBcylinder cylinder cap (8) and servo cylinder body (3) to be connected by cylinder cap attachment bolt (7).
Middle-size and small-size bite servo is adjusted oil cylinder (5), can adopt whole cylinder body structure.
The utility model has substituted to be installed on the straightening machine frame and has been constituted mechanism's formula roll-separating mechanism by motor reducer, leading screw and nut, and the band that can easily realize roll gap carries dynamic adjustment and dynamic straightening force and detecting in real time, reaches to shorten roll gap and adjust the time.
