Fig. 2, the continuous production equipment control principle of low-relaxation prestressed steel wire schematic diagram.
The specific embodiment:
Embodiment 1
As shown in Figure 1, the continuous production equipment of this low-relaxation prestressed steel wire comprises Medium Frequency Induction Heating Furnace 7, bosh 8, straining pulley 9, hauling machine 10, cutting machine 11, the admission machine 12 that is serially connected successively, pulled out unit 17 with connection and be connected in series before Medium Frequency Induction Heating Furnace.
Be to guarantee the normal operation of entire equipment, pull out at connection between each road drawing machine of unit and be provided with backward pull checkout gear 1 (see figure 2) that this checkout gear comprises two the orthogonal arm of force [L
1], [L
2], vertical intersection point is hinged on the fuselage its vertical arm of force [L
2] end tension force be installed detected wheel 13, the horizontal arm of force [L
1] end and fuselage between be connected in series a spring 14 and a pulling force sensor 15, pulling force sensor connects the control computer.Connection pulls out each road drawing machine of unit and buncher 4,16 drivings that straining pulley is controlled by computer.
This production equipment is the continuous production equipment of low-relaxation prestressed steel wire of expecting that from former finished product is finished continuously, and its production procedure is as follows:
Phosphatization raw material-multiple tracks drawing-Medium Frequency Induction Heating Furnace-bosh-straining pulley-hauling machine-cutting machine-finished product take-up
In this production equipment, dynamicly comprise that wire drawing machine, straining pulley, traction, take-up are all adopted by the variable-speed motor under the computer control and finish.The simultaneous computer unified monitoring the various physical parameters in each procedure, and whole production line is in the best duty all the time.Production line has been linked to be one to drawing procedure and underrelaxation chemical industry preface, and wire-drawing process is that the connection that buncher drives pulls out unit, is provided with the device of accurate mensuration backward pull between each wire drawing machine.This device is given computer with detected tension value, coordinates the rotating speed of each wire drawing machine by computer, realizes that connection pulls out.
The control principle (seeing accompanying drawing 2) of this production equipment underrelaxation tempering tension force:
The steel wire of being pulled out by extreme trace drawing machine wire drawing die 2 twines several circles on wire drawing jar 3, walk around tension force then and detect wheel 13, through wire drawing jar 3, pass Medium Frequency Induction Heating Furnace 7, water cooling plant 8, on straining pulley 9, twine several circles (frictional force that makes steel wire and straining pulley is greater than tempering tension force), pass through hauling machine, cutting machine again to the finished product take-up.
Straining pulley is kept the constant-speed operation of setting under computer control.Tempering tension force Fz produces by the speed difference of computer control extreme trace wire drawing machine motor 4 with straining pulley.
By accompanying drawing 2 as can be seen, the output valve of pulling force sensor is Fc.Fc=(Fz*cos α
1+ Fz*cos α
2) * L2/L1, owing to α when installing design work
1=α
2, and its changing value is very little, so Fz ≈ Fc/ (2cos α
1* L
2/ L
1), Fz is actual tempering tension force.
Computer is transformed into Fz to the Fc that receives, compares with the tempering tension force Fs of low-relaxation prestressed steel wire manufacturing technique requirent, and the buncher 4 of extreme trace wire drawing machine is carried out speed governing:
When Fz＜Fs, buncher 4 reductions of speed of computer instruction extreme trace wire drawing machine;
Work as Fz=Fs, buncher 4 speed of computer instruction extreme trace wire drawing machine are constant;
When Fz＞Fs, buncher 4 raising speeds of computer instruction extreme trace wire drawing machine.
Thereby the tempering tension force Fs that makes online actual tempering tension force Fz maintain the requirement of underrelaxation metallization processes stablizes constant.
The speed control principle of each wire drawing unit is identical with above-mentioned principle.Whole production line is all adjusted under the control of computer in real time.
