ラの速度を設定して運転を開始していた。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an induction heating device that changes its heating capacity between the initial stage of operation and the subsequent stage of operation. Conventional induction heating devices (hereinafter referred to as heaters) operate by setting the voltage of the power supply to provide a predetermined power to the induction heating coil, and by setting the speed of the drive pinch roller so that the workpiece is processed at a predetermined processing speed. had started.

に於いては運転初期から常に所定処理能力で加熱
するものであつた。 In this case, the predetermined processing speed is determined from the processing capacity of the heater in subsequent processes (for example, pressing, shearing, etc.) and is, of course, less than the maximum processing capacity of the heater. That is, conventional heaters always heat at a predetermined processing capacity from the beginning of operation.

のである。 The present invention aims to shorten the operating time, which has not been considered in the past, and provides one means for this purpose. That is, the aim is to shorten the rise time at the initial stage of operation by focusing on the fact that the processing speed of the subsequent process of the heater does not affect the processing speed of the heater at all until the leading end of the workpiece reaches the outlet of the heating coil.

That is, in the figure, 1 is a workpiece (for example, billet, bar material, etc.), 2 is a pinch roller for feeding the workpiece 1, 3 is an induction heating coil that applies power to the workpiece 1, 4 is a power source for the induction heating coil 3, and 5 is a indicates a sensor (for example, a limit switch, a photoelectric switch, etc.) that is attached to the outlet of the induction heating coil 3 and detects when the tip of the workpiece 1 has arrived.

上に寄与できる。 At the beginning of operation, until the tip of the workpiece 1 reaches the sensor 5, the maximum power that the power source 4 can have is applied to the induction heating coil 3, and at the same time, the speed of the drive pinch roller 2 is increased to a speed commensurate with the power, and heat treatment is performed. When the tip of workpiece 1 reaches sensor 5,
By returning the heater to a predetermined processing capacity that matches the subsequent process (returning to the preset power and speed), it is possible to shorten the time it takes for the tip of the workpiece 1 to reach the sensor 5, and improve production efficiency. Can contribute to improvement.
一般的に大型ヒータの場合、ワークサイズが大
きく、コイル長も長いため、ワーク先端がコイル
出口に到達するまでの時間は長いのでこの発明に
よる効果は顕著であると言える。 Generally, in the case of a large heater, the workpiece size is large and the coil length is long, so it takes a long time for the tip of the workpiece to reach the coil outlet, so it can be said that the effects of the present invention are significant.
又上記例はワーク送りの駆動法としてピンチロ
ーラ式を例にあげたがプツシヤー式、ウオーキン
グビーム式等、のヒータにも応用出来る。 Further, in the above example, the pinch roller type was used as the drive method for feeding the workpiece, but it can also be applied to pusher type, walking beam type, etc. heaters.

加熱するようにしたので、特に弊害を生じること
なく、運転時間を短縮できる効果がある。 As described above, in the initial stage of operation, the workpiece is heated near the maximum processing capacity of the apparatus until the tip of the workpiece reaches the vicinity of the outlet of the induction heating coil, and when the tip of the workpiece reaches the vicinity of the outlet of the induction heating coil, Since heating is performed at a predetermined processing capacity lower than the vicinity of the maximum processing capacity, there is an effect that the operating time can be shortened without causing any particular adverse effects.
