Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electromagnet coils, in particular to a tool for quickly replacing an electromagnet shell. Background Art
[0002] An electromagnet is a device that generates electromagnetism when electricity is applied. A conductive winding matching its power is wound around the outside of the iron core. This coil with current flowing through it is magnetic like a magnet. It is also called an electromagnet. We usually make it into a bar or hoof shape to make the iron core easier to magnetize. In addition, in order to demagnetize the electromagnet immediately when the power is off, we often use soft iron or silicon steel materials with faster demagnetization to make it. Such an electromagnet is magnetic when the power is on, and the magnetism disappears after the power is off. However, when the electromagnet is manufactured, there will be defects, rust spots, indentations, missing materials, etc. on the electromagnet shell or the lower yoke plate, and the electromagnet coil will be scrapped due to appearance defects. By replacing the shell and end plate, the electromagnet coil can be used normally; but in actual use, there are the following problems: At present, it relies on manual labor to cast the end plate out of the shell from the inner hole with a screwdriver and pry the copper wire coil out of the shell; manual shell removal is inefficient, and the shell end plate copper wire coil is tightly sealed, which is difficult to pry out, and the labor intensity is high. During operation, it is very easy to cause scratches on the inner hole of the copper wire coil and the surface of the end plate, resulting in scrapping. Utility Model Content
