Description
Affiliated technical field
The present invention relates to metal working process and equipment thereof, particularly a kind of Steel Wire Heat Treatment and straightening complex machining process and device thereof.Technology of the present invention and device are fit to mechanical workout factory to be adopted.
Background technology
In prior art, the production of steel wire is serialization, generally all is rolled into plate-like supply applying unit through rolling the steel wire of delaying, and applying unit must will could be used after its straightening, and some steel wire also will improve its physicals through Overheating Treatment.Relatively ripe for the straightening technology of rounded section steel wire, but still have very big difficulty for the straightening of special crosssection steel wire, frock complexity not only, and be difficult to reach conforming effect.Injure the surface of steel wire in addition easily.Though the tension force straightening is a kind of method of steel wire straightening, this method only is fit to the straightening of light gage wire, should not be used for the thick steel wire or the steel wire of noncircular cross section, therefore has significant limitation.
Summary of the invention
But the object of the present invention is to provide the steel wire of various cross-sectional shapes of a kind of wide adaptability straightening and size, and can heat-treat Steel Wire Heat Treatment and straightening complex machining process and the device thereof that improves the steel wire physicals to steel wire simultaneously.
The hot place of steel wire of the present invention amount includes with the straightening complex machining process uses a tension device that steel wire is applied tension force, and its step is as follows:
＜1〉allows steel wire electrically contact the contact by two of an electric heater continuously, make the thermal treatment temp of the needs that the steel wire between two contacts is heated to;
＜2〉allow the steel wire after heating cool off fluidic controlled chilling device, steel wire is cooled off fast carry out required thermal treatment by a spray;
＜3〉allow steel wire after handling by a tension device that constitutes by clamping running roller and tension motor, steel wire is straightened under hot, and in process of cooling subsequently, finalizes the design.
Be used to realize that the device of technology of the present invention includes a tension device, it is characterized in that also having:
(a) one electrically contacts contact and one by two bottom brackets, two and can debug the electric heater that low-voltage high-current transformer constitutes, two electrically contact contact and are separately positioned on two bottom brackets, and the output terminal of adjustable low-voltage high-current transformer divides and is connected with two bottom brackets.
(b) place the shower that is provided with several cooling fluid mouth sprays of electric heater rear end and the controlled chilling device that valve constitutes.
(c) tension device is arranged at the rear end of controlled chilling device.
In preferred version of the present invention:
Described electric heater output voltage is 20-70V, and outward current is 100-5000A.So that security in the assurance production process and operability, and the impact of minimizing of trying one's best to electrical network.Concrete operating voltage and electric current decide according to productivity, Heating temperature and section of steel wire size.
Two of described electric heater electrically contact the distance of touching, and promptly steel wire heating segment length 1-10 rice is suitable.The oversize steel wire that causes shakes, the influence operation; It is too high that too weak point can cause electric current, makes rate of heating too fast, wayward.There is following relation in the length electricalresistivity of steel wire heating segment length L and voltage U and electric current I and processed steel wire (ohm/meter):
L＝U/I/ρ
Described to electrically contact contact be a twin roll contact that has steel wire trough in the middle of being, rotated by the gear driven of adjustable speed motor, reduction box and pair of meshing.
On electrically contacting steel wire heating section between the contact, two of electric heaters also are provided with a thermal insulation casing, to reduce thermosteresis.
Tension device of the present invention is made up of support, the two rollers and the torque motor that have a steel wire trough as prior art.Also can adopt the driven by motor friction plate to produce moment and replace torque motor, but with torque motor for well, it is controlled easily, the moment that is produced is more stable.The tension force that tension device is applied to steel wire is suitable with the 20-50 kilogram, generally can steel wire is stretching with its tension force, the steel wire drawing-down can not exceeded again.
As for steel wire Trace speed of the present invention, because the length of the power of this parameter and Heating temperature, input and heating zone is relevant, when Heating temperature improves and heading-length when increasing then Trace speed minimizing; Power input increases then, and Trace speed increases.Therefore, selected selected should being as the criterion of Trace speed with actual measurement.
The roller that electrically contacts contact that electric heater unit is used can become with steel or copper, processes corresponding grooved according to silk material cross-sectional shape to be processed on roll surface, obtains to contact to greatest extent to guarantee roller and steel wire, also prevents the steel wire distortion simultaneously.
When needs carry out steel wire thermal treatment and straightening recombining process, discous steel wire is pulled out, allow it pass two couples contact roller of electric heater unit, through passing the clamping roller of tension device behind the controlled chilling device again, adjust the flow and the tension force of pressure and tension device of the output voltage of wire travelling speed, heading-length, electric heater unit and electric current, the spray fluid (pressurized air, water or oil) that adopts then, can start each and install steel wire is carried out straightening and thermal treatment product.The steel wire of pulling out from the tension device rear end can carry out blanking by desired length by the stock cutter that is arranged on the tension device rear end.
From technology of the present invention and the device as can be seen, compared with the prior art the present invention has following advantage:
But the steel wire in the different steel grades of 1 straightening, different size and cross section, adaptability is good, and is indeformable, straightening precision height.
2, in straightening, can comprise annealing, scold fire, solid solution and thermal treatment such as modified, improve the physicals of steel wire steel wire.
3, technology of the present invention and install fairly simple, easy operation, good stability, easy to utilize.
