A kind of ignition coil iron core stamping and forming equipment

Abstract

The invention discloses stamping formation equipment for ignition coil iron cores and relates to the field of stamping formation. The stamping formation equipment for the ignition coil iron cores comprises a conveying track and a stamping die, a silicon steel plate moves along the conveying track, an upper module and a lower module are matched to complete blanking operation on the silicon steel plate in the conveying process, then stamping formation is carried out, and the iron cores are obtained. In the operation process, a punch set composed of a plurality of first punches is matched with anunloading opening set to complete primary blanking of the silicon steel plate, then second punches and second unloading openings are matched to carry out the blanking operation on the silicon steel plate repeatedly, accordingly, all strip materials needed for preparing one iron core are obtained, and the strip materials subjected to blanking by the second punches and stored in the second unloading openings form iron core structures under the stamping effect of the second punches. The stamping formation operation of the iron cores is completed by adopting the stamping die, so that the purposesof improving the precision and stability of the stamping formation operation are achieved, and the purpose of improving the iron core forming quality is achieved accordingly.

Description

technical field [0001] The invention relates to the field of punching and forming, in particular to an ignition coil iron core punching and forming equipment. Background technique [0002] The core components of the automobile engine ignition device include an ignition coil and a switch device. The ignition coil includes an iron core and two sets of coils wound on the iron core, a primary coil and a secondary coil. When the primary coil is connected to the vehicle-mounted low-voltage power supply, as the current increases, a magnetic field is generated around the primary coil, and the iron core stores magnetic field energy; when the switch device disconnects the primary coil circuit, the magnetic field of the primary coil decays rapidly, and the secondary coil senses High voltage, that is, to obtain the pulse voltage required for the spark plug ignition of the car engine. [0003] The original traditional iron core processing is to cut the silicon steel plate into multi-sta...

AI Technical Summary

Problems solved by technology

In the above-mentioned traditional processing operations, the lamination of the single-piece strips is fixed by manual work. During the manual work, the laminations will be misaligned, and there are small gaps between the single-piece strips, resulting in the formation of the iron core. Low resistivity, low magnetic induction, high loss, poor high-frequency response, small inductance of the iron core, and small ignition energy of the ignition coil. There are improvements in the existing technology
