Coil with bent hook locks and manufacturing equipment of coil

Abstract

The invention discloses a coil with bent hook locks. The tail ends of wire rings of a coil body are bent towards the interior of the coil body to form hook parts to be hooked on the wire rings so as to form the bent hook locks. Equipment for manufacturing the coil with the bent hook locks comprises a cutting knife feed mechanism and a rotating knife feed mechanism which are arranged on a machine base. The cutting knife feed mechanism comprises a bending knife and a fixed cutting knife which are fixed to the machine base. The cutting knife feed mechanism further comprises a moving cutting knife driven by a cut-off air cylinder, so that part of wire rings of the coil are cut off to form the tail ends of the wire rings. The tail ends of the wire rings are bent towards the interior of the coil body. The rotating knife feed mechanism comprises a rotating knife, a rotating knife feed air cylinder, a bearing pedestal, a rotating shaft and a gear and rack mechanism, so that the bent hook locks are formed on the head of the coil body by the rotating knife. The bent hook locks are manufactured on the coil, and therefore the use stability of the coil can be enhanced, and the human body can be prevented from being hurt. The equipment for manufacturing the coil with the bent hook locks is easy and convenient to operate.

Description

technical field [0001] The invention relates to a coil and production equipment for making a crotch lock on the coil. Background technique [0002] Current coils on the market such as figure 1 As shown, the coil body 10 is composed of a plurality of continuously wound wire loops. The coil in use will leave the tail ends 11 of the wire rings at both ends of the coil body 10. The tail ends 11 of the current wire rings are rough and not smooth. , often with burrs, even with pointed parts, which will inevitably cause harm to the human body during use; moreover, the tail end of the current wire loop is open, and objects hanging on the coil are often caused by the deformation of the wire loop during use. displacement, or even fall off. Therefore, how to solve the above existing problems has always been a difficult problem for coil manufacturers and coil users. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a...
