Referring to shown in Fig. 7, Fig. 8, Figure 14, described driven support case 44, its structure is close with Active support case 41, is arranged symmetrically relative to the installation central plane of the two；Compared to Active support case 41, there is overhanging shaft part 4411 driving shaft 441 only one end that the driving shaft in driven support case 44 has been arranged in the opposite side of driven shaft, and driven support case 44 in horizontal plane, and is not provided with reducing motor.
Work process and the principle of the present embodiment are as follows:
The present invention uses four carrying roller back-up rolls, four carrying rollers divide two groups to be symmetricly set on Active support case and driven support case, power is provided by the reducing motor being arranged on Active support case, its drive path is: the reducing motor on Active support case passes motion to the driving shaft being arranged in Active support case being connected with it, after again by the primary gear speed reducing in Active support casing, drive the drive sprocket motion being coaxially connected with gear wheel, drive sprocket passes motion to two driven sprockets being arranged symmetrically with relative to Active support case central plane by chain, two driven sprockets and two roller carrier shafts are connected, and two carrying rollers and two roller carrier shafts are connected, in the power that the reducing motor being mounted on Active support case provides, it is ultimately transferred to two carrying rollers being arranged on Active support case；Reducing motor is also by the driving shaft being connected with it and the shaft coupling coupled with driving shaft simultaneously, pass motion to a power transmission shaft, the driving shaft that power transmission shaft is arranged in passing motion to driven support case by coupled shaft coupling, then two carrying rollers being arranged on driven support case are passed motion to by the gear drive identical with Active support case and Chain conveyer.By above-mentioned transfer route, can realize the power of reducing motor, synchronize constant speed passes to four carrying rollers being symmetricly set on Active support case and driven support case.
For improving quenching cooling effect, air jetting device use the blast that 3 storage airducts offers are relatively stable, three storage airducts, relative to the most uniform state of workpiece, every storage airduct is each provided with spray public attention of one group up to 29.When workpiece carries out spraying wind, constant speed rotation workpiece, sprays wind owing to workpiece is carried out at each annulus at 3 simultaneously, compressed air cooling effect can be made to be improved；For improving cooling effect further, reduce workpiece ambient temperature, the catcher of exhausting system it is provided with in the underface of workpiece, hot blast around workpiece can quickly be taken away timely by this catcher by air exhauster, to form the lower synergy inhaled of upper spray, cooling effect can be significantly improved with this, and the working environment of operator can be improved.
Before roll carries out air-blast quenching, workpiece temperature is difficult to reach to quench temperature required, need to heat it, be provided with heater for this, and heater quantity is two, is arranged in workpiece both sides；For improving the stablizing of combustion gas air pressure, heater have employed the round steel pipe being relatively large in diameter as gas storage space, and be equidistantly provided with up to 33 firn-jet heads on steel pipe and heat surface of the work.
For improving utilization of area rate, facilitating the handling work of workpiece and the quick adjustment of shower nozzle distance, air jetting device and heater are arranged on linkage, can realize motor-driven folding.When workpiece need to heat, air jetting device is rotated away under connected linkage effect, and heater is under connected linkage effect, is adjusted to proper operation position, and this operating mode is as shown in Figure 15；When workpiece need to carry out compressed air cooling, heater is rotated away under connected linkage effect, and air jetting device is adjusted to suitable operating position under connected linkage effect, and this operating mode is as shown in Figure 10.When handling workpiece, heater and air jetting device are all rotated away from workpiece under connected linkage effect, arrive the position of a safety.
