The inductor is commonly known as the high frequency head. The inductor plays a key role in the whole process of high frequency, medium frequency and ultra audio induction heating. The structure, shape and size of the inductor are the core issues of induction quenching technology, which has a direct impact on the induction quenching quality, production efficiency and energy consumption of parts, because the development of appropriate induction coil is the key to induction quenching to obtain high quality, high efficiency An important way to save energy. We have explained the problems needing attention in the manufacturing process of the inductor, and when making the copper coil, it should be noted that the copper parts become harder with the greater deformation. Therefore, most manufacturers retreat the fire once every few bends to alleviate this situation. First heat it until it turns red, and then quickly enter the water for cooling. These intermediate annealing processes can prevent the pipe from cracking during manufacturing. As a professional manufacturer of high-frequency induction heating equipment, we believe that the sensor maintenance and maintenance methods are also very important!
As an important part of high-frequency induction heating equipment, inductors are naturally sloppy from material selection, design and production. Each pair of inductors is made of high-quality copper tube according to the specification and shape of heat treatment workpiece. Generally, in mass production, it is better to have three sets of inductors, which are conscious of production and use. The second set is repaired in the maintenance group, and the other set is standby in the tool library. The inductors will also be worn after long-term use. If you do not pay attention to maintenance and repair, it will not only shorten the service life of the inductors, but also directly affect the quality of heat treatment effect,
So how to maintain the induction coil in the process of daily use?
It is explained from the following aspects:
1. To install correctly:
The most basic requirement for the use of the equipment is correct installation, and the contact plate, whether bolts, cams, etc., shall be close to the output end of the quenching transformer, and the contact surface shall be clean without oxide scale. At the same time, the effective ring and working clearance must reach the specified value to prevent short circuit and other accidents.
2. The workpiece heated by quenching shall meet the requirements of workpiece size. The size of the workpiece is the same as that of the process. The size of the quenching surface and the positioning surface of the workpiece shall meet the process requirements to prevent the sensor from being damaged.
3. Check the size of the effective ring regularly. The effective ring must be checked regularly. If errors are found, they must be changed in time. The clearance between the effective ring and the working must reach the specified value to avoid production short circuit, burn, etc. Therefore, the axis of the effective ring and the axis of the workpiece shall be concentric as far as possible, and the relevant positioning blocks and plates must be kept parallel or vertical.
4. Clean and wipe the working surface of the effective ring in time. The quenching surface of the workpiece is not allowed to have residual iron filings. The contact between the inductor and the workpiece will ignite and burn the high-frequency inductor.
5. Regularly use the internal circulation sensor of descaling agent to remove the scale inside. The effective circle with the largest current carrying capacity shall regularly check the outlet water temperature. The outlet water temperature must not exceed 50 ℃.
