The roll line of aluminum recycling is normal line important in aluminium rolling process.The height of roll line has considerable influence to the direction of motion after aluminium rolling, and too high or too low meeting makes aluminium nose, the safety of influence of rolled stability and breast roll, and serious words can make strip pierce roller system curling round the roll accident even occurs.Aluminum foil rolling technique is to the requirement of roll line, and must close under roll gap state, the roll surface junction of double-working, within being positioned at standard roll line ± 0.5mm.So the location of roll line is very important.
Existing aluminium process equipment generally adopts manually adjustment or encoder location to the location of roll line.Manual adjustment estimates scale by operating personnel manually to adjust roll line, relatively simple for structure, and shortcoming is that location is inaccurate, easily produces larger error.Encoder location encoder is arranged on hydraulic motor or drives on screw mandrel, and by detecting code device signal, hydraulic control motor or motor, realize the location of roll line; Shortcoming is that encoder easily falls pulse, and after repeatedly adjusting roll line, roll line zero-bit can be drifted about, and causes roll line to be located inaccurate.
Summary of the invention
Technical problem to be solved by this invention is, provides that a kind of System's composition is simple, measurement accuracy good, the aluminum recycling roll line automatic positioning equipment of accurate positioning.
In order to solve the problems of the technologies described above, aluminum recycling roll line automatic positioning equipment of the present invention, comprise the cambered surface pad of supporting roller bearing seat, the cambered surface pad of supporting roller bearing seat is installed the lower wedge that end face is inclined-plane, the top of lower wedge has the upper wedge that the lower surface coordinated with lower wedge is inclined-plane, also comprise the hydraulic motor being connected with screw body, the end of screw body is connected on the side end face of wedge, upper wedge is provided with the encoder that can detect wedge and move horizontally, on the signal output part link position input module of encoder, input module connects CPU module, CPU module is connected on a proportioning valve by Analog input mModule, the industrial computer of CPU module also with one for input control parameter and display working condition is connected.
Described encoder has encoder stay cord, the side of upper wedge is provided with pulley, and the top that pulley walked around by encoder stay cord is connected on wedge.
After adopting above-mentioned structure, due to the wedge up and down arranged, the hydraulic motor that wedge can be driven to move horizontally and the encoder be connected with upper wedge, the CPU module arranged and industrial computer, can by the position of wedge under the absolute value encoder signal framing of feedback, the signal of feedback is through PLC process, Industrial Control Computer input roller footpath (backing roll and working roll roller footpath) is sent in PLC, then process, PLC exports analog signals to motor controller, make motor operation, its vibrational power flow advantages of simple, System's composition is simple, error is little, accurate positioning, measurement accuracy is good.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of aluminum recycling roll line automatic positioning equipment of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, aluminum recycling roll line automatic positioning equipment of the present invention is described in further detail.
As shown in the figure, aluminum recycling roll line automatic positioning equipment of the present invention, comprise the cambered surface pad of supporting roller bearing seat 9, the cambered surface pad of supporting roller bearing seat 9 is provided with the lower wedge that upper surface is inclined-plane, the top of lower wedge has the upper wedge 3 that the lower surface coordinated with lower wedge is inclined-plane, also comprise the hydraulic motor 1 being connected with screw body 2, the end of screw body 2 is connected on the side end face of wedge 3, upper wedge 3 is provided with the encoder 4 that can detect wedge and move horizontally, on the signal output part link position input module 6 of encoder 4, input module 6 selects Siemens SM338 module, input module 6 connects CPU module 7, CPU module 7 is connected on a proportioning valve 11 by Analog input mModule 10, CPU module 7 selects Siemens SM331 module, the industrial computer 8 of CPU module 7 also with one for input control parameter and display working condition is connected.
Say that said encoder 4 has encoder stay cord further, the side of upper wedge 3 is provided with pulley 5, and the top that pulley 5 walked around by encoder stay cord is connected on wedge 3.
Visible by said structure, the present invention makes wedge move horizontally by a fluid motor-driven screw mandrel, contact surface due to two wedges is oblique, therefore wedge is descended can to move up and down along with upper moving horizontally of wedge, the below of lower wedge is the cambered surface pad of aluminium process equipment upper backup roll bearing block, moving up and down like this by lower wedge, just can change the position of roll line, one end of absolute value encoder stay cord is connected to the upper wedge moved horizontally, so just can by the position of wedge under the absolute value encoder signal framing of feedback, the signal of feedback is through PLC process, calculate the physical location of wedge, this is actual displacement.Industrial Control Computer input roller footpath (backing roll and working roll roller footpath) is sent in PLC, then processes, calculate the position that wedge needs to arrive, this is given displacement.Compare these two data, PLC exports analog signals to motor controller, makes motor operation.
The course of work of the present invention is as follows:
Aluminum recycling roll line automatic positioning equipment of the present invention can be divided into executing agency, testing agency and controlling organization three part;
Executing agency comprises hydraulic motor, hydraulic motor and magnetic valve thereof, coaxial screw body, roll line wedge, proportioning valve, Siemens SM331 module; The voltage of Siemens SM331 module output ± 10V is to proportioning valve, proportioning valve output pressure, make hydraulic motor work, the coaxial screw mandrel of fluid motor-driven rotates, and the screw mandrel of rotation drives the linkage being arranged on wedge, and wedge is moved horizontally, by the sloped contact surface of upper and lower wedge, just upper wedge can be moved horizontally the vertical movement converting lower wedge to, thus realize the adjustment of roll line, on 2000 aluminium foil mills, the gradient of wedge is 6 degree.
Testing agency comprises absolute value encoder, pulley, Siemens SM338 module, stay cord one end of absolute value encoder is fixed on wedge, by the guiding of pulley, absolute value encoder is arranged on the outside of mill hood, finally the line of absolute value encoder access Siemens SM338 module, when SM338 module often receives 4096 signals, the stay cord change 100mm of absolute value encoder, and the corresponding displacement 100mm of analog quantity 4096.
Controlling organization comprises Siemens's CPU module, Industrial Control Computer.Controlling organization carries out computing to detection signal, controls executing agency, and the position display calculated on operation screen, check for operator.The step of process is as follows:
