Description
Technical field
The invention belongs to electric wire twisted wire class field of mechanical technique, be specifically related to a kind of frame winch drum tension force ratio valve control system.
Background technology
The frame winch tension force Finial device of domestic production at present, the mode of controlling tension force is directly by manual adjustments pressure regulating valve, to control the tension force of drum, at twisted wire process tension force, can not change with the dishful of drum and the variation of blank panel, and drum overtension can cause conductor, can be stretched; Too small conductor can be loose, is unfavorable for twisted wire.
Summary of the invention
The object of the invention is to overcome existing drum overtension causes conductor to be stretched; Too small conductor can be loose, is unfavorable for the problem of stranding process; Thereby invented this frame winch drum tension force ratio valve control system.
The technical solution adopted in the present invention is:
A kind of frame winch drum tension force ratio valve control system is comprised of supersonic reflectoscope, support, proportioning valve, tension force cylinder, tension pulley, pressure regulating valve and PLC; Supersonic reflectoscope is arranged in support, and support is fixed on the end disc of cage side, and tension force cylinder, tension pulley are installed on cage body framework; The gas outlet of pressure regulating valve is connected by tracheae with proportioning valve air inlet, connects with two tension force cylinders in the gas outlet of proportioning valve.
Native system adopts electronic monitoring and control system to follow the tracks of the wiring quantity of drum, and according to shallow, the full degree signal transmission of drum to PLC, by PLC, controlled the air inflow of pneumatic proportional valve, how much and synchronously tension force changed with wire coil device amount, thereby reach permanent tension force, control, solved tension force problem rambunctious in stranding process.
Accompanying drawing explanation
Fig. 1 frame winch drum tension force ratio valve control system air pressure control principle drawing.
Fig. 2 supersonic reflectoscope installation site schematic diagram.
Embodiment
With reference to accompanying drawing, frame winch drum tension force ratio valve control system operation principle is: drum 3 unwrapping wire processes excessively in, if tension force cylinder 6 pressure remain unchanged always, along with unwrapping wire drum 3 disk tracks, by reducing greatly gradually, tension force will while increasing gradually, will not have a strong impact on twisted wire quality if do not change at any time Tensity size by little.Drum unwrapping wire moment (F*R) equals the moment of friction f*r[F that tension force cylinder 6 imposes on tension pulley 7: laying tension; R: draw drum radius; F: the frictional force that cylinder pressure produces; R: tension pulley radius].By the known laying tension F=of above formula (f/R) * r, because r is constant, only have f/R constant, laying tension could be realized constant, and frame winch drum tension force ratio valve control system just has wire tension control function.Frame winch drum tension force ratio valve control system is comprised of supersonic reflectoscope 1, support 2, proportioning valve 5, tension force cylinder 6, tension pulley 7, pressure regulating valve 8 and PLC.Supersonic reflectoscope 1 is arranged in support 2, and support 2 is fixed on cage body 4 side disks.Tension force cylinder 6, tension pulley 7 are installed on cage body 4 frameworks; The gas outlet of pressure regulating valve 8 is connected by tracheae with proportioning valve 5 air inlets, connects with two tension force cylinders 6 in the gas outlet of proportioning valve 5.In the present embodiment, tension force cylinder 6 has two groups, guarantees that the pressure that tension force cylinder 6 acts on tension pulley 7 is even.During work, source of the gas enters pressure regulating valve 8(model AC2000 by tracheae), by pressure regulating valve 8, regulate inlet pressure size in OK range; Supersonic reflectoscope 1 inductive head is aimed at unwrapping wire drum 3, with supersonic reflectoscope 1 in real time the disk track (R) of detection unwrapping wire drum 3 signal and feed back to PLC.PLC will carry out after computing according to tension force (F) and (R) corresponding relation, generate control signal control ratio valve 5[and see accompanying drawing 1, model is MPPE-3-1/4-6-010] and the automatic pressure of adjusting tension force cylinder 6, generate corresponding moment of friction f*r, keep f/R constant, thereby make wire obtain constant tension force.
