Rise press contact signal of the signal using hydraulic cylinder in place, it is ensured that measurement pair of rollers steel pipe has enough pressure to be allowed in steel pipe
Advanced direction produces frictional force.
C. to improve efficiency and setting accuracy in pinch roll course of conveying, using dual-speed control, in target position 50mm
Within conveyed with minuent, more than 50mm using being carried out at high speed conveying.Control accuracy is less than 3mm.The work of equipment is improve
Industry rate also substantially increases positioning precision.
The invention has the beneficial effects as follows：Transformation device for measuring length of steel tube system, mitigates the labor intensity of operator, improves
Cutting speed, improves yield, reduces energy consumption, it is to avoid during manual measurement, the operation of plant equipment brought to survey crew
Injury, the certainty of measurement that improve steel pipe is to effectively improve automatization and the standardization of measuring length of steel pipe, is conducive to carrying
The high market competitiveness.
Description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Specific embodiment
With reference to Fig. 1 specific illustrative embodiments：
Steel pipe length measuring system device, described steel pipe length measuring system device include pipe cutting machine 1, and the side of pipe cutting machine 1 is arranged
The opposite side for having cutter head 2, pipe cutting machine 1 is provided with center roller-way 3, is provided with steel pipe can be pressed from both sides on described center roller-way 3
The pinch roll 4 for sending；3 groups are provided with the both sides of described center roller-way 3 to penetrating electrooptical device；First group to penetrating electrooptical device 5
It is 5000mm with the spacing between cutter head 2, second group is 8000mm to the spacing penetrated between electrooptical device 6 and cutter head 2, the 3rd group
Spacing to penetrating between electrooptical device 7 and cutter head 2 is 10500mm；Survey is provided between described pipe cutting machine 1 and center roller-way 3
Amount roller 8, measurement roller 8 are connected with lowering or hoisting gear 9, are connected with the roller shaft of measurement roller 8 with shaft encoder 10, described 3 groups
To penetrating electrooptical device, pinch roll, measuring roller, lowering or hoisting gear, be connected with controller with shaft encoder；Steel pipe is on the roller-way of center
Jing pinch rolls are pinched, and steel pipe is moved to pipe cutting machine, when the required length of steel pipe being input on controller is more than 8000mm, steel pipe Jing
The 3rd group is crossed to penetrating during electrooptical device, just starts effectively counting with shaft encoder；When the required length of steel pipe being input on controller
More than 5000mm, during less than 8000mm, steel pipe through second group to penetrating electrooptical device when, just start effectively meter with shaft encoder
Number；When the required length of steel pipe being input on controller be less than 5000mm when, steel pipe through first group to penetrating electrooptical device when, coaxially
Encoder just starts effectively counting.
Optimal way is that described pinch roll 4 is connected with frequency conversion motor 12, the spacing between the tail end and cutter head of steel pipe
Conveying is carried out at high speed more than adopting during 50mm, when carrying out using low speed when being smaller than 50mm between the tail end and cutter head of steel pipe
Conveying.
Concrete operations are as follows：
1st, the length of required steel pipe is input on controller.
2nd, area's steel pipe to be cut is entered on the roller-way of center, now measuring roller can rise automatically, be close to steel tube surface, together
When pinch roll Automatic-clamping can rotate, drive steel pipe to advance.During scale, measurement roller measures roller meeting by hydraulic cylinder jack-up
With steel pipe synchronous axial system, it is arranged on measurement roller with shaft encoder, measurement roller is again rotated with coaxial decoders-Synchronous, from same
The pulse signal of shaft encoder output is input to controller, reaches required size through computing.
After d, survey length terminate, steel pipe sends into certain size, and Workpiece clamping is driven and unclamped by pipe cutting machine, and pinch roll stopping is simultaneously
Open, bracket rises, to keep stablizing for steel pipe.Measurement roller can decline automatically, ready to cut pipe tail.Required condition
After all meeting, can be with pipe cutting pipe tail.Start by main shaft, lathe is started working and cut, and cutting is finished, and main shaft stops, work
Part loosens, and bracket declines, the material returned.
Cutter head is 5000mm to first group of distance to penetrating electrooptical device, and cutter head is to second group of distance to penetrating electrooptical device
For 8000mm, cutter head is 10500mm to the 3rd group of distance to penetrating electrooptical device.Steel pipe is allocated to after the roller-way of center from area to be cut,
Steel pipe moves right, when pipe tail through certain group accordingly to penetrating electrooptical device when, just start effectively counting with shaft encoder.Control
D512 on device is scale value, and D16 is difference=corresponding distance-scale value to penetrating electrooptical device to cutter head.
For example：Scale value is 10000mm, leaves corresponding 3rd group to penetrating electrooptical device when tube head moves right, coaxially
Encoder just starts effectively counting, its difference=10500-10000=500mm.During pinch roll conveying steel pipe, front 450mm is height
Fast feed status, rear 50mm are low speed feed status.Here pinch roll frequency conversion motor.Can slow down when fast close, therefore
The high precision of feed.It is that measurement roller is withstood by hydraulic jack with shaft encoder.Roller shaft is connected with same shaft encoder, is realized
Roller outer end is synchronous with pipe to move ahead, and is controlled after controller process, realizes automatic gauging production.
If scale value is 4700mm, difference is 300mm, accordingly to penetrating electrooptical device when starting counting up with shaft encoder
For first group.If scale value is 7800mm, difference is 200mm, accordingly to penetrating light Denso when starting counting up with shaft encoder
It is set to second group.
