Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.
Refer to Fig. 1 and Fig. 2:
The present invention be achieved in that a kind of bearing steel Frequency Induction Heating surface not the equipment of ftractureing comprise feed arrangement 1, accumulator 2, induction heater 3, thermometric The Cloud Terrace 4, temperature three sorting unit 5, intermediate frequency power supply 6;
Described feed arrangement 1 is arranged on the rear of described accumulator 2, described induction heater 3 is arranged on the front of described accumulator 2, described thermometric The Cloud Terrace 4 is arranged on the front of described induction heater 3, the inclined downward of described thermometric The Cloud Terrace 4 is provided with temperature three sorting unit 5, and described intermediate frequency power supply 6 is arranged on the bottom of the surperficial equipment that do not ftracture of described bearing steel Frequency Induction Heating.
Feed arrangement has Pneumatic assembly cylinder, hopper.Storing stand has platform, cylinder.Induction heater is made up of induction coil (copper pipe), fire proof material of furnace lining, insulation board, framework, water-cooled guide rail, and employing waits pitch of turn mode, has preheating, heating, insulation three area segments.Thermometric The Cloud Terrace has temperature sensor, Displaying Meter.Temperature three sorting unit has owes warm, qualified, burning triple channel.Intermediate frequency power supply is static frequency-conversion device.Feed arrangement is connected with described accumulator by Pneumatic assembly.
Instant invention overcomes the phenomenon of GCR15SiMn bearing steel cracking, decrease heat treatment link, material scaling loss is few, energy-conserving and environment-protective, and heating and temperature sorting control automatically, avoid artificial disturbance; There is not steel surface crackle, the phenomenon that metallographic structure does not offset; Product quality improves, and reduces energy consumption, reduces artificial, for client improves benefit, makes GCR15SiMn bearing steel in heating in medium frequency, be able to effective application.
Feed arrangement by cylinder by the beat that sets with air as power, heating blank is pushed induction heater.Storing stand is mainly used in blank to be placed on platform, and platform can hold the blank of some as required, is ploughed under in the hopper before feed arrangement by material by material, can reduce labour intensity like this by required heating beat by the cylinder arranged in storing stand.It is induction heat core component that device adds, and is made up of induction coil (copper pipe), fire proof material of furnace lining, insulation board, framework, water-cooled guide rail.Eddy-current heating adopts electromagnetic induction principle, by the kelvin effect of electric current, generated heat toward conducted inside from blank surface, heating blank is rapidly heated, because bearing steel is to heating sensitivity characteristic, under surface does not have destressing situation, Fast Heating will cause face checking, therefore need when designing heating inductor to select suitable frequency, general diameter is at φ 70mm-φ 110mm blank, He Ne laser is in 1000HZ, the above blank He Ne laser of φ 110mm-φ 180mm is at about 500HZ, the coil turn of induction heater to take into full account the heat sensitivity of bearing steel, induction heater will realize slow intensification, heater length will lengthen, such as 500KW intermediate frequency power supply needs the inductor length of joining to be not less than 4000mm, by two joint designs, 1250KW heats the blank of large gauge usually, and because the heat time is long, therefore inductor design can meet the demands at about 5000mm.The pitch of turn modes such as induction heater employing, are designed with preheating respectively
,heating, insulation three area segments, the main purpose of preheating is exactly consider the heat sensitivity of GCr15SiMn bearing steel, slowly heat up in preheating zone, play the effect of bearing steel surface destressing, this point is particularly important, and the thermal treatment zone is mainly used in being rapidly heated, and heat preservation zone is mainly for meeting the core table temperature difference requirement of blank, make the core table temperature difference less, play the effect of samming.Thermometric The Cloud Terrace mainly plays detection effect, by the temperature detection to blank discharging opening, feed back in instrument, detect actual temp, it is temperature required whether inspection reaches production, pass the signal to temperature three sorting unit, requirement blank according to setting enters one of " owing temperature ", " qualified ", " burning " passage by three sorting units, enters next process, reclaims as entered the laggard feed box of " owing temperature " passage, the words entering " qualified " passage will carry out next procedure, forging molding.Enter the laggard feed box of " burning " passage to reclaim.Intermediate frequency power supply is a kind of static frequency-conversion device, three-phase main-frequency 50HZ convert alternating current is become intermediate frequency single-phase alternating current by main employing thyristor, be mainly used in eddy-current heating, manufacture of iron and steel by melting, hard heat treatment etc., this device main circuit adopts " AC-DC-interchange ", transformation system is made up of three-phase fully-controlled bridge rectification circuit, filter reactor, parallel inverter circuit, control system is made up of integrated circuit, zero-pressure sweep method is adopted to start, security of system, reliable, environmental protection, energy-conservation, easy to maintenance.
The above is only to preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
