Description

Electrical steel core manufacturing apparatus having a control module that can be flexibly applied to the height and thickness of the steel plate

The present invention relates to an apparatus for manufacturing an electrical steel sheet core, and more particularly, to an apparatus for manufacturing an electrical steel sheet core having a control module flexibly applicable to the height and thickness of a steel sheet.

In general, a motor is composed of a stator and a rotor. In a motor used in a drum washing machine, the rotating rotor is located on the outside and the stator is located inside the rotor. In the case of this type of stator, the tooth portion of the core around which the coil is wound has a core formed radially outward along the outer circumferential surface of the core.

This type of core is called an outer type stator core. On the other hand, a core in which the tooth portion of the core is directed toward the center of the circle of the core is referred to as an inner type stator core.

A general method of manufacturing a conventional stator core is to punch an arc-shaped core divided into 6 parts from an electrical steel sheet, laminate the punched cores to form 6 split core laminates, and then stack the 6 split cores. It is to make one core by welding the sieve.

However, since this method punches an electrical steel sheet in a curved arc shape, there is a problem in that a lot of material costs are consumed because there are a lot of parts that are left after being punched out from the electrical steel sheet and discarded.

If the electrical steel sheet can be punched in a straight line, the amount of discarded electrical steel sheet can be greatly reduced.

In order to improve these problems, Korean Patent Registration No. 10-0911880 (hereinafter referred to as "Prior Patent Document 1") discloses a spiral core that cuts an electrical steel sheet in a straight line and efficiently arranges each process to increase production and lower manufacturing cost. Manufacturing equipment is disclosed.

In addition, Korean Patent Registration No. 10-0902628 (hereinafter referred to as "Prior Patent Document 2") discloses an apparatus for manufacturing a stator core by winding a punched electrical steel sheet in a spiral shape and pressing it in two stages.
