Design and manufacture of induction ring on pipe fitting equipment

Fitting equipment in the work the heating effect of induction coil, the working current of induction coil, injustice, depends on the size, and the shape of the induction coil, coil number, lead to the length of the copper tube, work is closely related to the factors such as material, shape, to make the most effective use of the equipment of the power, according to the work of the material, the shape of induction coil, the reasonable design is very important.The design of induction coils should generally follow the following principles:

1. The shape of the induction ring of pipe fitting equipment should be determined according to the shape of the working heating surface. The production principle should use the copper pipe in the induction part and the working heating surface to be parallel or equidistant, and the current flow direction between adjacent turns is consistent.

2. Determine the number of inductor turns

The following situations should be double-loop or multi-loop structure: non-magnetic materials such as copper, aluminum, etc.?Planar heating with workpiece diameter ≤25mm?Heating with an external magnetic field

3. The clearance adjustment principle between induction ring and workpiece of pipe fitting equipment is as follows

The gap between the small work and the induction ring should be controlled in 3-5mm

The gap between the larger workpiece and the induction ring should be determined as follows

When the power regulation rotation has been adjusted to the maximum, the current indication is also maximum but the heating rate is very slow, the clearance between the work and the induction coil should be reduced or the number of induction coil turns should be increased.

When the power regulating knob is adjusted to the maximum but the current display is not up to half of the maximum current, the gap between the workpiece and the induction coil should be increased or the number of induction coil turns should be appropriately reduced.

4, for the use of external magnetic heating (such as plane heating, work hole quenching, etc.) or for non-magnetic metal heating, can use different shapes of ferrite materials magnetic concentration can greatly increase the output power of the equipment.

5. The lead length of induction ring should not be too long, which will increase the loss of equipment.

6. When the heating method determines the shape of the induction coil and the thermal efficiency is low, the power can be considered
