Abstract
The thermal treatment double-line producing device for a high-strength prestressed steel rod of the utility model solves the problem of low production efficiency because the existing equipment can only treat single-strip steel wires. The utility model principally comprises two sets of wire flippers, straighteners, towing devices, induction heating devices, quenching devices, water cooling tanks, shearing devices and take ups, wherein, the towing devices are respectively provided with one intake roller on both ends of a final-stage drive shaft; the upper parts of the intake rollers are respectively corresponding to a compression roller; the installation shafts of the compression rollers are controlled by compressing devices adding force. Two sets of output inductors are fitted in each induction heating device. Two steel wires respectively pass through the output inductors. The device has the advantages of increasing production and stable quality. The full line speed of the double line exceeds 70*2=140 m, and the production capacity almost is up to two times of a single line. The process of the thermal treatment is easily realized and the production quality is more stable because the speed of per strip of steel wire does not exceed the speed of the single line. The utility model has the advantages of reasonable structure, life-time dilatation, energy conservation, increasing efficiency, cost cutting and economizing investments; the utility model can decrease more than 60% investments of a set of equipment.
Description
[technical field]: the utility model relates to a kind of high-strength prestress rod iron heat treating facilities.
[background technology]: the prestressed steel bar full name is a steel bar for prestressed concrete, also is the pile tube steel wire, the PC rod iron.It mainly is used as the arrangement of reinforcement of high strength prestressed concrete pipe pile (PHG).Prestressed steel bar is that the medium carbon low alloy steel wire rod is engraved several negative thread grooves or pulls into the light face through drawing, forms through quenching, tempered modifier treatment again.Be widely used in Highrise buildings ground pile tube, coastal beach harbour pile tube, rivers bridge pier pile tube, Longspan Bridge, aspects such as Highrise buildings.All high-strength prestress rod iron heat-treatment production lines all are the single line operations at present, promptly only a steel wire is handled, travelling speed is up to 80m/min, and this speed is near operational limit, and then difficulty is very big to rethink the quality that improves travelling speed and guarantee processed steel wire simultaneously.Because improve the steel wire travelling speed that is improve quenching, tempering speed, its result can make the steel wire grain fineness number reduce, and the tissue conversion not exclusively causes the fatigue resistance reduction of steel wire, degradation under the comprehensive mechanical property.The travelling speed of more external production units is the fastest to be 9/60 meter of Φ, exactly in order to guarantee quality product.
[summary of the invention]: the utility model purpose is exactly to solve existing installation can only handle the problem that makes production efficiency low to the wall scroll steel wire, provides a kind of high-strength prestress rod iron thermal treatment two-wire production unit, to enhance productivity.
The utility model mainly comprises actinobacillus device, straightening device, towing mechanism, induction heating device, quenching device, cooling trough, shear and take-up composition, it is characterized in that actinobacillus device, shear and take-up are two groups of formations arranged side by side; Wherein towing mechanism comprises frame, the motor of installing in the frame, transmission rig in the wheel casing that this motor is installed on transmission belt and belt wheel drive chassis, final stage transmission shaft two ends in the transmission rig are passed by the wheel casing both sides, its end respectively is equipped with a conveying roller, each correspondence of conveying roller top is equipped with a pressure roller, and the pressure roller installation shaft is by the hold-down gear pressurized control.
Be furnished with two groups of output inductor blocks in each induction heating device, two steel wires are respectively by passing in the output inductor block.
Advantage of the present utility model and effect: 1, output raising, steady quality: two-wire speed completely surpasses 70 * 2=140 rice, output has almost reached single-step twice, because the speed of every steel wire does not all surpass single-step speed, the easier realization of its thermal treatment process, quality product is more stable; 2, rational in infrastructure, the life-span prolongs: install because the conveying roller of two-wire is designed to the two ends symmetry, it is more reasonable to install than single line pressure roller one side cantilever, has therefore prolonged the work-ing life of pressure roller, pressure roller shaft and bearing greatly; 3, energy efficiency, reduce cost: the steel wire power consumption per ton of this production line reduces about 50 degree than single line, with Φ 9 steel wires is example, with day work 18 hours, year work was calculated in 300 days, two-wire is than about 680,000 degree that economize on electricity in single line year, and the operator only increases by 2 people than single line, has therefore saved the energy, reduce cost, increased benefit; 4, save investment: this equipment general speed is near single-step twice, and floor space is identical with single line, need not enlarge factory building, and facility investment and two cover single wire device are relatively, can reduce more than 60% of single device, greatly reduce facility investment.
