[0052] The temperature measuring device 200 is electrically connected to the control device 100 and is located on one side of the drum 700 for monitoring the temperature of the drum rope groove 710 .
[0053] Specifically, the pump group of the water spray device 600 is electrically connected to the control device 100, and is used to spray water to cool the heated drum rope groove 710. The temperature measuring device 200 can monitor the actual temperature of the drum rope groove 710.
[0054] like Figure 2 As shown, as a preferred embodiment of the digital quenching device for a drum rope groove of the utility model, a drum rotating system 500 includes a drum clamping device 530 , a drum rotating device 520 and a base 510 .
[0055] The reel clamping device 530 and the reel rotating device 520 are respectively installed on both sides of the base 510; the reel rotating device 520 is connected to the first end of the reel 700; the reel clamping device 530 is connected to the second end of the reel 700, and the reel 700 is rotatably connected between the reel clamping device 530 and the reel rotating device 520.
[0056] The roll rotating device 520 is preferably driven by a servo motor.
[0057] As a preferred embodiment of the digital quenching device for the drum rope groove of the utility model, a speed change device 521 is provided on the drum rotating device 520 , and the speed change device 521 is electrically connected to the control device 100 .
[0058] The speed change device 521 is electrically connected to the reel rotating device 520 and can adjust the operation of the reel rotating device 520 to change the rotation speed of the reel 700 .
[0059] like Figure 3 As shown, as a preferred embodiment of the digital quenching device for the drum rope groove of the utility model, the control device 100 includes a given signal comparator 101, an analog-to-digital converter 110, a digital intermediate frequency power supply 120, a speed control device 130 and a temperature control device 140.
[0060] like Figure 1 As shown, as a preferred embodiment of the digital quenching device for the drum rope groove of the utility model, the digital quenching device also includes an intermediate frequency transformer 300, the quenching sensor 400 is electrically connected to the intermediate frequency transformer 300, and the intermediate frequency transformer 300 is electrically connected to the digital intermediate frequency power supply 120.
[0061] Preferably, the water spray device 600 has a plurality of water spray holes of φ2 mm and is fixed to one side of the intermediate frequency transformer 300 , and the intermediate frequency transformer 300 is electrically connected to the digital intermediate frequency power supply 120 .
[0062] like Figure 1As shown, when the digital quenching device for the drum rope groove of the utility model is used, preferably, the drum 700 to be quenched is first manually transported to the drum rotating system 500 through the workshop lifting device, and the middle hole of one end of the drum 700 is manually clamped through the drum rotating system 500; at the same time, the drum clamping device 530 clamps the other end.
[0063] After the drum 700 is clamped safely and reliably, the gaps between the quenching sensor 400, the temperature measuring device 200 and the water spraying device 600 and the drum rope groove 710 are adjusted, and the control device 100 is started to control the voltage and other auxiliary water cooling systems to enter the quenching preparation state.
[0064] After the control device 100 is started, the control device 100 sends a given signal 800. As the given signal 800 automatically increases, the voltage output by the quenching sensor 400 at the output end of the medium frequency transformer 300 increases accordingly; the drum rope groove 710 is affected by the magnetic field of the quenching sensor 400, and the temperature begins to rise. When the temperature measuring device 200 detects that the drum rope groove 710 reaches, for example, 850° C. (according to the material and process requirements, the heating temperature is controlled between 800° C. and 900° C.), the drum rotating device 520 on the drum rotating system 500 drives the drum 700 to start rotating at a uniform speed, preferably at a speed of 20 m / min. At the same time, the water spraying device 600 sprays water to cool the heated rope groove, thereby achieving the purpose of quenching.
[0065] like Figure 3 As shown, as a preferred embodiment of the digital quenching device for the drum rope groove of the utility model, the speed control device 130 includes:
[0066] The speed loop comparator 131 is electrically connected to the speed change device 521 .
[0067] The speed regulator 132 is electrically connected to the speed loop comparator 131 , the drum rotating device 520 and the given signal comparator 101 .
[0068] The speed regulator 132 can adjust the rotation speed of the reel rotating device 520 and can also feed back a signal to the given signal comparator 101 .
[0069] Preferably, the digital quenching device for the drum rope groove of the utility model has a double closed loop, one of which is a speed loop. In this embodiment, the speed loop comparator 131 and the speed regulator 132 are arranged to form a speed loop with the speed change device 521, the drum rotating device 520, the given signal comparator 101, the analog-to-digital converter 110, the digital intermediate frequency power supply 120 and other related components.
[0070] In the speed loop, after the speed loop comparator 131 is electrically connected to the speed regulator 132, the signal is fed back to the given signal comparator 101 to control the output power: when the speed is lower than the set value, the voltage of the given signal 800 is increased to increase the output power; when the speed is higher than the set value, the voltage of the given signal 800 is reduced to reduce the output power; so that the rotation speed of the reel 700 and the output power of the digital intermediate frequency power supply 120 are within the quenching process range. In addition, the speed loop comparator 131 can give a signal to the speed regulator 132, and the speed regulator 132 adjusts the rotation speed of the reel rotating device 520.
[0071] The speed loop can adjust the rotation speed of the drum rotating device 520 while ensuring the logical relationship between the output power and the rotation speed. Figure 3 As shown, as a preferred embodiment of the digital quenching device for the drum rope groove of the utility model, the temperature control device 140 includes:
[0072] The temperature comparator 141 is electrically connected to the temperature measuring device 200 .
[0073] The temperature regulator 142 is electrically connected to the temperature comparator 141 and the given signal comparator 101 .
[0074] The temperature regulator 142 can feed back a signal to the given signal comparator 101 .
[0075] Preferably, the digital quenching device for the drum rope groove of the utility model has a double closed loop, and the other loop is a temperature loop. In this embodiment, by setting the temperature comparator 141 and the temperature regulator 142, the temperature measuring device 200, the given signal comparator 101, the analog-to-digital converter 110, the digital intermediate frequency power supply 120 and other related components can form a temperature loop.
[0076] In the temperature loop, after the temperature comparator 141 is electrically connected to the temperature regulator 142, the signal is fed back to the given signal comparator 101 to control the output power: when the temperature is lower than the set value, the voltage of the given signal 800 is increased to increase the output power; when the temperature is higher than the set value, the voltage of the given signal 800 is reduced to reduce the output power; so that the temperature of the drum rope groove 710 and the output power of the digital intermediate frequency power supply 120 are within the quenching process range.
[0077] The temperature loop can adjust the output power of the digital intermediate frequency power supply 120 while ensuring the logical relationship between the output power and the temperature of the drum rope groove 710 .
[0078] The digital quenching device for the drum rope groove of the utility model adopts digital double closed-loop control to improve quality and efficiency. Figure 3 The digital double closed loop diagram further explains:
[0079] The double closed loops are a speed loop and a temperature loop. The given signal 800 of the control device 100 is a 0-10v analog signal, which is converted into a digital signal by an analog-to-digital converter 110 to control the digital intermediate frequency power supply 120, the drum rotating device 520 and the water spraying device 600.
[0080] Further, as a specific embodiment of the double closed loop, the process values of the heating temperature and the rotation speed are preset in the control device 100 according to the material of the drum 700. When the temperature measuring device 200 detects that the temperature of the drum rope groove 710 is deviated:
[0081] If the actual rotation speed is outside the process threshold, the control device 100 adjusts the rotation speed of the roll rotating device 520 through the speed change device 521, the speed loop comparator 131 and the speed regulator 132 to make the rotation speed reach the process value of the speed loop.
[0082] If the actual rotation speed is within the process threshold, the temperature loop is started, and the output voltage of the digital intermediate frequency power supply 120 is adjusted through the temperature measuring device 200, the temperature comparator 141 and the temperature regulator 142, thereby adjusting the voltage across the quenching sensor 400. The higher the voltage, the greater the output power of the quenching sensor 400. The temperature reaches the process value of the temperature loop through power adjustment.
[0083] As described above, the application of the double closed loop can effectively avoid the occurrence of system oscillation, control the quenching temperature and the rotation speed of the reel 700 within a reasonable range, and effectively ensure the quenching quality of the product reel.
[0084] As a preferred embodiment of the digital quenching device for the drum rope groove of the utility model, the digital intermediate frequency power supply 120 includes a rectifier, a filter, an IGBT inverter and a digital control system.

[0086] As a preferred embodiment of the digital quenching device for the drum rope groove of the utility model, the digital intermediate frequency power supply 120 is a single-phase power supply.
[0087] Preferably, the digital intermediate frequency power supply 120 is a single-phase power supply with a frequency of 1 kHz-10 kHz, and the output power is adjusted by adjusting the instantaneous peak value of the single-phase power supply.
[0088] As a preferred embodiment of the digital quenching device for the drum rope groove of the utility model, the diameter of the drum 700 to be quenched is 800mm-3500mm, and the length of the drum 700 is 1200mm-5000mm.
[0089] The reel 700 is preferably a large-scale special reel, with a minimum diameter of φ800 mm, corresponding to a length of 1200 mm; a maximum diameter of φ3500 mm, corresponding to a length of 5000 mm.
[0090] The utility model adopts a digital medium frequency power supply 120 to quench the drum rope groove 710. The quenching process is controlled by a double closed loop of speed and temperature, which can improve the uniformity of quenching hardness and the depth of the quenching layer. The surface hardness of the rope groove after quenching reaches HB280-380, and the quenching layer depth is greater than 2mm. The digital quenching process of heating, rotating, feeding back and spraying water is adopted to achieve the purpose of improving quality and efficiency.
