Abstract
The utility model provides a heating unit for a blank of a spring. Multiple groups of medium frequency induction heaters are used for carrying out movable and continuous heating for a blank of a spring to make the blank of a spring ordinarily reach the temperature needed by rolling manufacture within about 20 to 35 seconds. The utility model is especially suitable for processing the blank of a spring of 16 mm to 30 mm and has the advantages of low energy consumption, fast working speed and adequate quality. The requirement of production in bulk can be satisfied, and the productive environment is improved.
Description
The utility model belongs to the hot-work technology, is a kind of device that adopts the Medium frequency induction technology to make spring.
Present spring manufacturing is particularly big to diameter, the spring manufacturing that length is long generally is that the mode that adopts flame heating or electric furnace, electrically contact heating rolls after to blank heating and forms, but this class technology long processing time, power consumption is big and add the easy oxide skin etc. that produces in man-hour, and quality product is difficult for stable.
The purpose of this utility model is to utilize the Medium frequency induction technology to make a kind of heating unit, thereby makes the steady quality of blank heating, improves rate of heating, reduces capability of energy dissipation.
The utility model is to constitute like this: this device has the medium frequency induction heater＜1〉of two groups above (containing two groups), transporting mechanism＜2 〉, medium frequency induction heater＜1〉and transporting mechanism＜2〉are installed in respectively on the body＜3〉one by one, medium frequency induction heater＜1〉connects capacitor for electric induction heating system＜4〉and intermediate frequency contactor＜5〉and frequency converter＜6 〉, be convenient to red-tape operati, transporting mechanism＜2〉has stepless speed-regulating motor＜7 〉, support roller＜8〉and conveyer chain＜9 〉, conveyer chain＜9〉has connected support roller＜8〉and stepless speed-regulating motor＜7 〉, medium frequency induction heater＜1〉can adopt conventional making method to make in the present invention, this device is suitable for processing the blank of spring that diameter is 16mm--30mm, when the blank of spring of this type of size of processing, the power frequency of this device is 8000Hz, with order on body＜3〉5-7 group medium frequency induction heater＜1〉being installed is the best, wadding＜11〉in the medium frequency induction heater＜1〉can adopt carborudum tube, and the coil of every group of medium frequency induction heater＜1〉has one group of intersection contact＜10 〉.
Accompanying drawing 1 is a process unit synoptic diagram of the present utility model.
Embodiment of the present utility model: five groups of induction heaters are installed on the body, the coil turn of five groups of induction heaters is respectively 20 circles, 20 circles, 26 circles, 20 circles, 20 circles from the body inlet end to exit end, and coil is that 14 * 12 * 1.5 special-shaped side's copper tube coilings form.Well heater on body, places stepless speed-regulating motor, support roller and conveyer chain by the control of frequency conversion unit.During use, be 26 millimeters with a diameter, length is the inlet end that 2.7 meters blank is placed on body.On the support roller, under conveyer chain transmits, blank moves to induction heater, and pass induction heater, temperature by five groups of induction heaters is respectively 300 ℃, 600 ℃ and reaches 900 ℃ at last, at this moment send into bushing machine immediately and roll, so just finished the technology that rolls spring, finish these technology front and back and only need 20-30 second.
The spring of the utility model processing is heated evenly, quality is good and process velocity fast, power consumption is little.
