Abstract
The utility model provides a straightening machine screwdown gear for stainless steel strip, includes frame, servo motor, transmission shaft, transmission screw mechanism and upper work roll device, transmission screw mechanism includes lead screw, the suit screw outside the lead screw, the upper work roll device is connected to the lead screw lower extreme, the transmission shaft upper end links to each other with servo motor, transmission shaft middle part warp beam take up in the frame, transmission shaft lower extreme fixed connection screw, install the displacement sensor device with servo motor cooperation control upper work roll device drafts in the frame. The utility model discloses solve the current not high problem of stainless steel strip material straightening machine screwdown gear drafts control accuracy, the utility model has the characteristics of it adopts sensor technology to improve mechanical transmission efficiency, reduces driving error, reduce cost etc. To reduce drive mechanism.
Description
Technical field
The utility model belongs to straightener technical field, is specifically related to a kind of improvement of stainless steel band straightener screwdown gear.
Background technology
At present, often adopt motor driven belts to move worm-and-wheel gear at stainless steel band straightener screwdown gear to rotate, worm-and-wheel gear drives screw body motion thus realizes the change of drafts, consider that the screwdown gear of development to straightener of electronic sensor innovation technology improves on this basis, its drafts is made to obtain controlling more accurately, the different original curvature of rolled piece can be made to become rapidly homogeneous curvature if the drafts of stainless steel band straightener obtains suitable adjustment, strip shape quality is improved and can increase economic efficiency.
Existing screwdown gear structure: be made up of worm screw, worm gear, power transmission shaft, screw mandrel, roll feeding device.Wherein worm screw is by driven by motor, passes to worm gear by worm-and-wheel gear, and worm gear drives drive axis, and the internal thread on power transmission shaft is connected with screw mandrel makes converting rotary motion be vertical movement, and the final roll feeding device that drives moves up and down.Two groups of worm-and-wheel gears wherein in the frame of both sides are by a driven by motor, and two groups of worm-and-wheel gears can not be accomplished just the same, there is foozle and cause the displacement of roll feeding device to occur deviation.
Summary of the invention
The purpose of this utility model adopts many mechanism driving to cause drafts to control the not precisely improvement carried out for existing stainless strip straightener screwdown gear: reduce transmission mechanism thus obtain drafts adjustment more accurately.
Technical solution of the present utility model is: comprise frame, servomotor, power transmission shaft 2, drive lead screw mechanism and top working roll device, drive lead screw mechanism comprises screw mandrel, the screw be set in outside screw mandrel, screw mandrel lower end connects top working roll device, power transmission shaft 2 upper end is connected with servomotor, in the middle part of power transmission shaft 2, warp beam takes up in frame, and power transmission shaft 2 lower end is fixedly connected with screw; Described frame is provided with the displacement sensor device coordinating with servomotor and control top working roll device drafts.When the encoder accepts of servomotor end is to when requiring the signal of roll feeding device displacement from digital control system, motor starts to make corresponding rotation, at this moment displacement transducer is used for detecting the displacement of roll feeding device and whether arrives required position and this actual displacement signal feedback to digital control system, thus judge the distance of actual movement, and signal is sent to next step action of motor, form closed-loop control with this displacement transducer and servomotor and drafts is controlled accurately.
Described power transmission shaft 2 lower end is provided with the slot to make way for coordinating screw mandrel movement.
Described screw outer wall is provided with locating flange, and screw stretches into slot to make way and is fixed on power transmission shaft 2 lower end through the bolt be loaded on locating flange.
Described servomotor is identical with the quantity of drive lead screw mechanism, is more than one.
Described servomotor, drive lead screw mechanism are four.
The utility model device has selected servomotor on the drive means, and peripheral employing displacement transducer and its formation closed-loop control have more reliable precision controlling like this, and this way can improve the precision of drafts.Drive mechanism decreases transmission mechanism (worm-and-wheel gear), and this way can reduce driving error, improves transmission efficiency, reduces error, reduces production cost.
The driven by servomotor that 4 control accuracies are higher selected by the utility model screwdown gear, selects displacement transducer, and decreases transmission mechanism quantity, can obtain higher drafts precision controlling, and simplifies design and save the time, reduces costs.
Accompanying drawing explanation
Fig. 1 is screwdown gear schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described:
In Fig. 1, the utility model stainless steel band is with straightener screwdown gear by drive unit, and transmission mechanism and operating mechanism's (i.e. top working roll device) 5 form.Drive unit changes employing 4 servomotors 1 into and drives the drive lead screw mechanism be fixed on top working roll device 5 four angle points respectively, its displacement is made to obtain controlling more accurately, servomotor 1 is fixed in frame 3, external rack 3 is also provided with displacement sensor device, and displacement transducer and servomotor 1 form closed-loop control.Transmission mechanism adopts drive lead screw mechanism, drive lead screw mechanism is connected with top working roll device 5 with servomotor respectively, drive coupled drive lead screw mechanism part to rotate when servomotor 1 works, the rotation of this part passes to the screw mandrel 4 fixing with top working roll device by being threaded connection, and screw mandrel 4 is moved up and down thus drives top working roll device 5 to move up and down to reach the object adjusting drafts.Encoder is equipped with in servomotor 1 inside, is provided with displacement transducer to detect the distance of roll feeding device 5 movement, forms closed-loop control with this in frame 3, ensures the precision of drafts.
