Description
Technical field
The utility model relates to skew roller type straightener, particularly a kind of bar straightener angular adjustment apparatus.
Background technology
Existing WIRE FINISHING LINE region is mainly used skew roller type straightener to carry out the finishing of bar, improves linearity and the surface quality of bar.According to the bar of different conditions, by adjusting the roll gap size of straightener and the angle of smoothing roll, realize the aligning of bar.Straightener system for regulating angle is comprised of mechanical leading screw and hydraulic ram cylinders two parts, in original system for regulating angle, by partly use the method for encoder feedback at mechanical leading screw, carry out accurate location and the demonstration of angle, but the gap of machinery assembling and wearing and tearing have caused the inaccurate of angle demonstration, have caused very large puzzlement to straightener operating personnel's adjustment.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of bar straightener angular adjustment apparatus, in hydraulic ram cylinders side, used built-in displacement sensor to feed back, thereby by position ram cylinder piston rod position, show accurately smoothing roll angle, improved the convenient and stable of straightener adjustment and use.
In order to achieve the above object, the technical solution of the utility model is:
A kind of bar straightener angular adjustment apparatus, comprise mechanical side and the hydraulic pressure side of suitable work with it, mechanical side comprises motor 6, motor 6 is connected with leading screw 2, leading screw 2 front ends are provided with the first jacking block 1, leading screw 2 and the first jacking block 1 are all arranged in nut sleeve 3, hydraulic pressure side comprises fairlead 7, in fairlead 7, be provided with piston rod 4, piston rod 4 front ends are provided with the second jacking block 1-2, fairlead 7 bottoms are provided with end cap 8, are provided with displacement transducer 5 on end cap 8, and displacement transducer 5 inserts piston rod 4 inside.
The utility model is mainly comprised of mechanical side and hydraulic pressure side two parts.Mechanical side drives leading screw to rotate by motor reducer, leading screw advances or retreats in nut sleeve, leading screw front end contacts with jacking block, simultaneously, the automatic reverse when leading screw advances or retreat of hydraulic pressure side, adjusting hydraulic cylinder internal pressure is zero-pressure or high pressure, thereby common action is adjusted to suitable angle by roller system of straightening machine.
The Main Means that the utility model utilizes displacement transducer to feed back and locate as angle, solves the unsettled problem of angle feedback signal by linear displacement detection scheme.By angle being shown to being converted into linear pattern shows, reduce display error, improve operating accuracy.
Accompanying drawing explanation
Fig. 1 is mechanical side structural representation of the present utility model.
Fig. 2 is hydraulic pressure side structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
See figures.1.and.2, a kind of bar straightener angular adjustment apparatus, comprise mechanical side and the hydraulic pressure side of suitable work with it, mechanical side comprises motor 6, motor 6 is connected with leading screw 2, leading screw 2 front ends are provided with the first jacking block 1, leading screw 2 and the first jacking block 1 are all arranged in nut sleeve 3, hydraulic pressure side comprises fairlead 7, in fairlead 7, be provided with piston rod 4, piston rod 4 front ends are provided with the second jacking block 1-2, fairlead 7 bottoms are provided with end cap 8, on end cap 8, be provided with displacement transducer 5, and displacement transducer 5 inserts piston rod 4 inside, displacement for induction piston bar 4.
Operation principle of the present utility model: when angle reduces, hydraulic pressure side passes into hydraulic oil, cylinder piston rod 4 moves forward, supporting the second jacking block 1-2 moves forward, electric interlock starter motor 6 is rotated counterclockwise simultaneously, drive leading screw 2 rotate and move backward along nut sleeve 3, for smoothing roll provides, turn to space.And piston rod 4 is when moving forward, displacement transducer 5 is that magnetic material is made, accurate positioning piston bar 4 displacements, thus it is vertical to converse the angle of actual rotation.Vice versa, and when angle increases, motor 6 turns clockwise, and drives leading screw 2 to rotate and move forward along nut sleeve 3, and electric interlock magnetic valve commutation simultaneously, passes into hydraulic pressure side oil pressure and become zero-pressure, thereby complete angle adjustment.After adjustment finishes, hydraulic pressure lateral pressure oil commutates again, passes into high pressure, completes location and the locking of smoothing roll.
