Description

Technical Field

[0001] The utility model relates to the field of winding equipment, in particular to a hook needle for a winding machine. Background Art

[0002] The winding machine is a device used to wind copper wire around a magnetic core. The working process of the winding machine includes the steps of hooking the copper wire with a hook needle and then pulling the copper wire toward the hollow position of the magnetic core. As the holes of current products are getting smaller and smaller, the hook needles are also made very small, and the copper wire or enameled wire needs to be wound into a coil. During the winding work of the winding machine for smaller magnetic rings, the copper wire or enameled wire is repeatedly hooked and pulled by the winding hook needle for winding.

[0003] The existing hooks for winding machines are usually made of plastic materials to prevent the insulating paint on the surface of the enameled wire from being damaged when the hooks are hooked. The hooks made entirely of iron will damage and wear the surface of the copper wire, and the hooks made entirely of plastic are not strong enough. Application No. 202222939089.0 discloses a wire hook for a winding machine, the exterior of which is made of plastic, and metal reinforcement ribs are arranged inside the wire hook to improve the overall strength and increase the service life. However, the hook is small in size and the metal reinforcement ribs inside it are relatively small, so it is still easy to break during use. Utility Model Content
