Electromagnetic oven wire coil, processing method thereof and hot-press forming device

Abstract

The invention relates to an electromagnetic oven wire coil, a processing method thereof and a hot-press forming device. The electromagnetic oven wire coil comprises a wire spool made of fire resistant thermoplastic material, a coil and a coil groove wound at the top and a magnetic strip channel with a magnetic strip at the bottom, the coil is directly fixed by pressurizing and thermally melting the edge material of the coil groove; the wire spool is provided with a support rib, the coil groove is arranged on top of the support rib, and the magnetic strip channel with the magnetic strip is arranged at the bottom, and at least two ear clips are also arranged at the periphery of the wire spool. The material of the coil groove, which is higher than the coil part, is hot-pressed and deformed by the hot-press forming device and covers the top of the coil so that the coil is tightly pressed in the coil groove. In the invention, the coil or / and the magnetic strip is fixed by a hot-press die controlled by the hot-press forming device to greatly shorten the time for fixing the coil and the magnetic strip on a traditional electromagnetic oven wire coil, greatly improve the production efficiency and the rate of good products and greatly decreases the production cost of enterprises.

Description

technical field [0001] The invention relates to an electromagnetic cooker, in particular to a wire reel of an electromagnetic cooker, a processing method thereof, and hot pressing forming equipment. Background technique [0002] The traditional manufacturing method on the wire reel of the induction cooker is: first wind the copper wire on the wire reel with a winding machine, then coat the ribs on the wire reel with high-temperature resistant adhesive, then dry it, and then manually wrap the wire reel Shovel the excess uneven high temperature resistant adhesive on the top; then install the magnetic strip, and then use the same method as above to fix the magnetic strip to the bottom of the wire tray. This manufacturing method is easy to shovel the coil or magnetic strip during the production process, resulting in a high scrap rate, and the small scratches cannot be distinguished by the naked eye, which is likely to leave a safety hazard, and often requires a lot of human reso...

Problems solved by technology

However, this invention has higher requirements on the size of the groove for fixing the coil. If the groove is higher than the wire core, the bead is useless. If the groove is shorter than the wire core, the bead is subjected to a greater force, and the bead is easily damaged and loses the ability to fix the coil. effect
