Description
Technical field
The present invention relates to the cross roll straightener bite adjusting device of one of finishing equipment in the metallurgical machinery, especially can realize in the aligning process cross roll straightener bite servo and regulating system of dynamically the adjusting in real time of aligning roll gap size, a kind of two-stage tandem that the quick definite value of roll gap is made a concession and depressed reliably.
Background technology
At present, the roll gap of cross-roll straightening machine need be adjusted according to the diameter of aligning stocking, and method commonly used is with motor or manually is motive power, rotates through decelerator reinforcement rear drive leading screw, utilizes the relative displacement between leading screw and the nut to realize that roll gap changes; Another kind of new method replaces leading screw with hydraulic cylinder, by the position change roll gap of control piston.The former can't realize the adjustment of rolled piece roll gap in the aligning process, and number of spare parts is many, complex structure, cost height.Though the latter can satisfy the requirement of the high-speed, high precision cross-roll straightening machine on the tinuous production, the precision height of vital part--whole oil cylinder, complex structure, cost height, equipment long-time running instability.
Summary of the invention
For the hydraulic pressure that overcomes existing cross-roll straightening machine is adjusted the whole cylinder structure complexity that is adopted in the roll gap device, and the cost and the on-the-spot maintenance cost that reduce existing servo adjustment roll gap system, the problem that the reliability that minimizing produces because of the device fabrication precision reduces, the invention provides a kind of bite servo and regulating system, the above-mentioned technology contents of solution that can be convenient and reliable.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be: a kind of cross roll straightener bite servo and regulating system of two-stage tandem, comprise roll gap control circuit, proportional valve controller, proportioning valve, oil pressure sensor, plunger displacement sensor, it is characterized in that: use hydraulic pressure to adjust the control of valve group and adjust the secondary bite servo and regulating system that oil cylinder and standard oil cylinder are formed, can realize easily that the band of roll gap carries dynamic adjustment by bite servo with displacement transducer.
The cross roll straightener bite servo and regulating system of a kind of two-stage tandem of the present invention, servoBcylinder cylinder cap top is provided with two fuel feed holes, is connected with the standard oil cylinder with proportioning valve respectively, constitutes the two-stage tandem Adjustment System.
The cross roll straightener bite servo and regulating system of a kind of two-stage tandem of the present invention, the servoBcylinder plunger stretches out oil cylinder by the plunger guide ring and the plunger seal circle of an end setting of servoBcylinder cylinder body.
Bite servo of the present invention is adjusted oil cylinder, and servo-cylinder is entered the in-oil cylinder bite servo of servo adjustment the oily night of its rod chamber and adjusted oil cylinder by a servoBcylinder plunger that is arranged in servoBcylinder cylinder body and the servoBcylinder cylinder cap.
The invention has the beneficial effects as follows: keeping existing hydraulic pressure to adjust under the constant prerequisite of roll gap apparatus system function, effectively reduce the manufacturing cost of adjusting the roll gap device, very convenient user overhauls and safeguards, and greatly reduces maintenance cost.
Description of drawings
Fig. 1 is a hydraulic schematic diagram of the present invention
Fig. 2 is the vertical section structural map that bite servo of the present invention is adjusted oil cylinder (5) embodiment
Mark among the figure: 1. roll gap control circuit, 2. proportional valve controller, 3. proportioning valve, 4. oil pressure sensor, 5. bite servo is adjusted oil cylinder, 6. plunger displacement sensor, 7. reversal valve, 8. standard oil cylinder, 9. cylinder cap attachment bolt, 10. servoBcylinder cylinder cap, 11. servoBcylinder cylinder body, 12. the servoBcylinder plunger, 13. plunger guide rings, 14. plunger seal circles.
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), passing ratio valve control amplifier (2) will instruct and amplify rear drive proportioning valve (3) action, the pressure oil of hydraulic system enters (or outflow) bite servo by P mouth (or T mouth) through proportioning valve (3) and adjusts oil cylinder (5), the plunger of this oil cylinder is then done and is stretched out accurately moving of (or withdrawal), the displacement of plunger 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 (i), 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, proportioning valve (3) cuts out, and the piston of bite servo adjustment oil cylinder (5) is fixed on the position of setting.
When the roll gap of straightener needs fast quantification to change, control circuit (1) sends the oil cylinder instruction, reversal valve (7) action, the action of standard oil cylinder (8) total travel, the fluid of its rod chamber enters in the servo adjustment oil cylinder (5), servoBcylinder plunger (12) is done the fast moving of certain value, finishes the action of technological requirement.
As shown in Figure 2, the non-standard bite servo of setting is adjusted oil cylinder, its structure be by servoBcylinder plunger (12) by servoBcylinder cylinder body (11) one ends plunger guide ring (13) and plunger seal circle (14) stretch out oil cylinder; Two fuel feed holes are arranged at servoBcylinder cylinder cap (10) top, are connected with standard oil cylinder (8) with proportioning valve (3) respectively, constitute the two-stage tandem Adjustment System.
The present invention is keeping existing hydraulic pressure to adjust under the constant prerequisite of roll gap apparatus system function, change system and bite servo and adjusted the structure of oil cylinder, effectively reduce the manufacturing cost of adjusting the roll gap device, very convenient user overhauls and safeguards, and greatly reduces maintenance cost.
