Abstract
The invention provides a pressing-down device of a metal slat straightener, belonging to the metal slat straightener technical field. The invention is composed of four sets of pressing-down screw mechanisms which are symmetrically arranged at four corners and completely identical; the invention is characterized in that a spherical pad device and a short stroke servo cylinder are arranged between the lower end of each pressing-down screw and a movable transverse beam; the upper end of the pressing-down screw and the bottom of the short-stroke servo cylinder are provided with a displacement sensor. The invention has the advantages of realizing dynamic roller seam adjustment, exact location, stable straightening, improving the precision of the product, and prolonging the service life of the machine.
Description
Technical field
The invention belongs to the metal plate bands straightening technical field, be specifically related to a kind of metal plate bands straightening screwdown gear.
Technical background
At present, the screwdown gear of metal plate bands straightening has two types both at home and abroad, and a kind of is mechanical transmission structure, promptly is to drive the moved cross beam displacement by housing screw to realize the roll gap adjustment; Another kind is to drive the moved cross beam displacement by hydraulic cylinder piston to realize the roll gap adjustment.These two types respectively have pluses and minuses, and first type of shortcoming is can not realize in the course of the work dynamically adjusting the roll gap size, and processing performance is poor, and the roll gap positioning accuracy is low.Second type is all-hydraulic control, the control system complexity, and maintenance difficulties is big, the cost height.
Summary of the invention
The object of the invention provides a kind of metal plate bands straightening screwdown gear of new construction, can overcome the shortcoming that prior art exists effectively.
The present invention is achieved in that it is made of the identical press-down screw mechanism of quadruplet that is arranged symmetrically in four jiaos, it is characterized in that between every housing screw lower end and moved cross beam, being equipped with ball ring device and short distance servoBcylinder, displacement transducer is installed in the upper end of housing screw and the bottom of short distance servoBcylinder.Concrete structure is that the nut that matches with four housing screws is fixedly mounted on the entablature, motor drives four housing screws by decelerator and rotates in nut and displacement, adjustment is depressed in realization, the housing screw lower end is connected with the ball ring device by connecting screw, the lower end of ball ring device is connected with the piston of short distance servoBcylinder, short distance servoBcylinder lower end is installed in above the moved cross beam, in the bottom of housing screw upper end and short distance servoBcylinder displacement transducer is installed.Piston diameter in the short distance servoBcylinder is
Piston stroke L=2 * (l
1+ l
2).
In the formula, P is unidirectional total straightening force;
P is a hydraulic cylinder works pressure;
l
1Be dynamic adjustment amount, generally get 5～10mm;
l
2Be design margin, generally get 10～15mm.
Advantage of the present invention and good effect:
1.. hydraulicdriven short distance servoBcylinder mechanism and displacement sensor device are installed among the present invention, can realize dynamically adjusting in the course of the work roll gap, accurately location, the control of permanent roll gap.Can improve the precision of correcting product greatly.
2.. the ball ring device is installed among the present invention, can adapt to that in correcting process roll gap occurs lean forward, hypsokinesis, "Left"-deviationist, Right deviation, the out-of-level side force that produces, can make the rectification stable working, improve machine service life.
Description of drawings:
Fig. 1 is structural representation of the present invention (is example with single press-down screw mechanism).
Among the figure: 1---entablature; 2---housing screw; 3---nut; 4---the ball ring device; 5---the short distance servoBcylinder; 6---moved cross beam; 7---displacement transducer; 8---decelerator; 9---displacement transducer
The specific embodiment:
The present invention is made of the identical press-down screw mechanism of the quadruplet that is arranged symmetrically in four jiaos.Now illustrate with single press-down screw mechanism shown in Figure 1: the nut 3 that matches with housing screw 2 is installed on the entablature 1, motor drives housing screw 2 by decelerator 8 and rotate and do axial displacement in nut 3, housing screw 2 upper ends are equipped with displacement transducer 7, be connected with the ball ring device by connecting screw in housing screw 2 lower ends, the bottom of ball ring device is installed in above the short distance servoBcylinder 5, and the short distance servoBcylinder 5 that the bottom is equipped with displacement transducer 9 is placed on the moved cross beam 6.Four hydro-cushion cylinder assemblies are installed between moved cross beam and the entablature.During work, motor drives housing screw 2 rotations and does axial displacement by decelerator 8, forces moved cross beam 6 to move by ball ring device 4 and short distance servoBcylinder 5, reaches and adjusts the roll gap purpose.The short distance servoBcylinder of installing in the machine, ball ring device and displacement transducer can play dynamic adjustment, accurately location, the steadily effect of rectification.
Claims (2)
