Detailed Description
In order to better understand the technical solution of the present invention, the present invention is described in detail through specific embodiments.
Refer to fig. 1. The utility model discloses a device that is used for quick adjustment induction coil actual heating region length, include with main heating coil 10 matched with auxiliary coil 11, and the adjustable connection structure etc. between auxiliary coil 11 and the main heating coil 10.
The main heating coil 10 and the auxiliary coil 11 adopt a multi-turn spiral coil structure wound along the axial direction; the main heating coil 10 and the sub-heating coil 11 are arranged in parallel with their central axes parallel to each other. The main heating coil 10 is an induction coil for induction-heating a workpiece, and the auxiliary coil 11 is used for adjusting the actual heating region length of the main heating coil 10.
A first end 101 (shown as the left end) of the main heating coil 10 is connected to, for example, one of the terminals (e.g., the live or neutral terminals) of the medium frequency power supply, and a second end 102 (shown as the right end) of the main heating coil 10 is a free end (i.e., the first turn at the left end of the main heating coil 10 is connected to one of the terminals of the medium frequency power supply, and the first turn at the right end of the main heating coil 10 is a free end). A first end 112 (shown as a right end) of the auxiliary coil 11 is connected to another terminal (e.g., a neutral terminal or a fire terminal) of the intermediate frequency power supply, and a second end 111 (shown as a left end) of the auxiliary coil 11 is a free end (i.e., a first turn of the right end of the auxiliary coil 11 is connected to another terminal of the intermediate frequency power supply, and a first turn of the left end of the auxiliary coil 11 is a free end).
In this way, when the main heating coil 10 and the auxiliary coil 11 are electrically connected at a single point in the radial direction, even if a short circuit occurs in the radial direction at a certain position (certain turn) in the axial direction between the main heating coil 10 and the auxiliary coil 11, the circuit connecting the main heating coil 10 and the auxiliary coil 11 to the power supply is made conductive. I.e. along a loop formed between one of the terminals of the power supply, the part of the main heating coil 10 between the first end 101 of the main heating coil 10 to its shorted position, the part of the auxiliary coil 11 between the shorted position on the auxiliary coil 11 to the first end 112 of the auxiliary coil 11, and the other one of the terminals of the power supply. Whereas the part of the main heating coil 10 between the second end 102 of the main heating coil 10 to its short-circuited position and the part of the auxiliary coil 11 between the short-circuited position on the auxiliary coil 11 to the second end 111 of the auxiliary coil 11 are free from current flow due to the presence of the respective free ends.
Further, when varying the different radial connection positions between the main heating coil 10 and the auxiliary coil 11 in the axial direction, the length of the part of the main heating coil 10 between the first end 101 of the main heating coil 10 to its short-circuited position is varied.
Since the actual heating area length of the main heating coil 10 is determined by the effective length of the main heating coil 10 in the heating loop, that is, the actual heating area length of the main heating coil 10 is defined by the distance from the first end 101 of the main heating coil 10 to the connection position on the main heating coil 10, when the radial connection position between the main heating coil 10 and the auxiliary coil 11 in the axial direction is changed, the actual heating area length of the main heating coil 10 is changed accordingly, so that when the workpiece capacity is changed or the workpiece heating temperature is changed, the corresponding heating coil (inductor) is not required to be replaced, and the heating area length of the workpiece can be adjusted only by adjusting the connection position between the main heating coil 10 and the auxiliary coil 11, so that the heated workpiece temperature and the process can meet the requirements of customers.

Specifically, a plurality of first taps 14 may be provided at intervals in the axial direction on the outer ring of the main heating coil 10, while a plurality of second taps 13 corresponding to the positions of the first taps 14 are provided at intervals in the axial direction on the outer ring of the auxiliary coil 11, i.e., a plurality of tap pairs are formed. In this way, the main heating coil 10 and the auxiliary heating coil 11 can be conducted by connecting the first tap 14 and the second tap 13, which are opposite to each other, through only one shorting block 12.

For example, the short block 12 is shown connected to the fourth bisection point from right to left, and the actual heating region length of the main heating coil 10 at this time is the distance from the first end 101 of the main heating coil 10 to the fourth bisection point. If the length of the actual heating area of the main heating coil 10 needs to be reduced, the short-circuit block 12 can be connected with each pair of taps in the left direction; at this time, the length occupied by the auxiliary coil 11 in the loop increases accordingly. Conversely, if the actual heating area length of the main heating coil 10 needs to be increased, the short-circuit block 12 can be connected with each pair of taps in the right direction; at this time, the length of the auxiliary coil 11 in the circuit is reduced accordingly.
In a preferred embodiment, the first taps 14 may be provided on the main heating coil 10 at intervals of 1 to 2 turns; similarly, the auxiliary coil 11 is provided with second taps 13 at intervals of 1 to 2 turns, the second taps corresponding to the positions of the first taps 14.
