Description

Technical Field

[0001] The utility model relates to a device for winding a winding coil of a rectangular electromagnet, belonging to the technical field of electromagnet maintenance equipment. Background Art

[0002] Lifting electromagnets are widely used in steel enterprises. The commonly used lifting electromagnets are generally round and rectangular. Rectangular lifting electromagnets have single-chamber, double-chamber, four-chamber specifications, etc. They are often used in the lifting and transportation of steel ingots, steel billets, and steel plates in steel rolling mills, as well as the storage and loading of finished products. Figure 1 As shown, the cross-section of the core of the rectangular lifting electromagnet is small at both ends and large in the middle. This is done to make the conductor of the flat and long coil close to the core. However, the straight side of the coil is very long. When the coil is wound, the conductor will inevitably "swell" and bend outward. The coil is easy to bulge in the middle of the winding, and the circumference of the coil is long. This lengthens the length of each turn of the coil. Therefore, the winding process is inconvenient, and the wound coil is prone to uneven arrangement between turns. The wound "swollen" coil cannot be used due to large size deviations, or it is difficult to install it into the shell, which can easily damage the insulation between the coil and the cavity and cause failures, shortening the service life and posing great quality risks. Therefore, it is necessary to improve the method of winding the rectangular lifting electromagnet coil. Utility Model Content
