Further, described voltage-stabilized power supply is AC220V/DC10V dc source.
Further, the resistance of described measuring resistance is 20K Ω, rated power is 1W, measurement length L is 100mm.
Further, the stroke of described guide rod is 70mm.
Compared with prior art, the utility model has the advantage of: designed band steel straightener bottom smoothing roll position control is simple in structure, has simplified position detecting element and installation method, has greatly improved production efficiency.Simultaneously, because the position of lower roller frame is in process of production adjustable by PLC controller, can better adapt to produced on-site situation, in addition, the automated closed-loop of having realized controller due to the position of lower roller frame regulates, thereby a large amount of manual interventions is used in the position that has replaced lower roller frame, manually the process to the position adjustments of lower roller frame, has realized the automation of the position of lower roller frame.
Accompanying drawing explanation
Fig. 1 is that the utility model is at the structural representation of the state of use.
Fig. 2 is the utility model electrical principle schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Band steel straightener bottom smoothing roll position control shown in Fig. 1 and Fig. 2, comprise the first supporting drift 2 that afterbody is connected with hydraulic cylinder 1 and be positioned at the supporting of second on the first supporting drift 2 drift 3, the cephlad-caudal of the second supporting drift 3 is contrary with the cephlad-caudal of the first supporting drift 2, the inclined-plane of the inclined-plane of the first supporting drift 2 and the second supporting drift 3 is bonded to each other, also comprise voltage-stabilized power supply 8, PLC controller 9, guide rod 6 and one end are provided with the measuring resistance 5 of measuring stick 4, measuring stick 4 is connected with the spring in measuring resistance 5, one end of guide rod 6 is connected with the head of the first supporting drift 2, the other end of guide rod 6 is connected with measuring stick 4, measuring resistance 5 is arranged on fixed support 7, described measuring resistance 5 is powered by voltage-stabilized power supply 8, to ensure the work of measuring system accurate stable.Measuring resistance 5 outputs voltage signal to PLC controller 9.Voltage-stabilized power supply 8 is AC220V/DC10V dc source.The parameter of measuring resistance 5 is as follows: model OF10LP100[stroke 100mm, standard Standard resistance range: 20K Ω]; Maximum real resistance: 20K Ω; Total resistance tolerance: standard level ± 5% (J) micron order ± 3% (H); Independent linearity tolerance: standard level ± 0.7%/± 0.5% micron order ± 0.4%/± 0.25%; Power: 1.0W; Noise: <100 Ω E.N.R.; Electric stroke: 100 ± 1mm; Mechanical trip: about 103mm; Insulaion resistance >100M Ω (500V.D.C.); Dielectric withstanding voltage: 1 minute (900V.A.C.); Friction: <15N (1500gf).PLC controller 9 adopts Siemens S7-400 series, and the following CPU:S7-4162DP of parameter is main frame, model: 6ES7416-2XK04-0AB0, and the method for employing remote I/O station collection signal, the module of collection signal is: 6ES7-7KF02-0AB0.
The know-why of this device is to adopt measuring resistance 5 to be connected with regulating the first supporting drift 2 of lower roller frame 10 height, when propping up the first supporting drift 2 in diverse location, also there is a corresponding resistance in measuring resistance 5 simultaneously, thereby export a voltage signal, be directly inputted to PLC controller 9, through PLC, be converted into the height of corresponding lower roller frame 10.Hydraulic cylinder 1 stretches out and drives the first supporting drift 2 to move to the right, thereby the first supporting drift 2 makes the upwards operation of lower roller frame by promoting the second supporting drift 3 risings; In like manner, when hydraulic cylinder, retract and drive the first supporting drift 2 to move left, thereby lower roller frame 10 is moved downwards.When hydraulic cylinder 1 is retracted into root, measuring stick 6 stretches out the longest; When hydraulic cylinder 1 contracting is protruding, guide rod 6 is outwards operation thereupon, makes measuring stick 6 to the interior contraction of measuring resistance 5.The range ability of guide rod 6 is 70mm, first, by manually the first supporting drift 2 being returned to mechanical zero, then by PLC controller 9, by measuring resistance 5, is read the measured value of current mechanical location, as electric with reference to zero value N
0, this work is called mechanical school zero.PLC controller 9 reads the current positional value Nr of the first supporting drift 2 by analog module, the actual fortune position height of lower roller frame 10 H=(Nr-N
0) * M*I, wherein:
H: lower roller frame physical location height (mm)
Nr: the actual current positional value Nr of supporting drift that reads
N
0: when school is zero, read the current positional value Nr of supporting drift
M: each is worth corresponding supporting drift range ability (mm) to read supporting drift
I: the tangent ratio of supporting drift is 26/480.
