Abstract

PURPOSE:To facilitate formation of laminated iron cores by a method wherein an iron core laminating device forming and laminating thin band like magnetic materials is constituted so that the device may perform cutting, forming and laminating operations at the same time. CONSTITUTION:An end of magnetic material 1 is automatically fed by a feeder 2 to pass a cutter 3 and further automatically set to a travelling guide 4 comprising a travelling unit travelling up to the specified position of cutting dimension interlocking with said feeder 2 and an iron chuck unit. Next said feeder and said travelling guide 4a interlockingly and continuously feed the magnetic material 1 and when the dimension between said travelling guide 4a and said cutter 3 attain to the specified distance, the feeding of said magnetic material 1 is automatically stopped to start cutting operation. The cut off magnetic pieces independently travel between core mold 6 and forming guide 5 to reset the holding iron core end. During this time, a standby travelling guide 4b travels to set the end of magnetic material 1 fed by said feeder 2 by means of said iron chuck unit travelling to the specified position of cutting dimension interlocking with said feeder a. These operation may be continuously repeated to laminate magnetic pieces forming specified iron core construction.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an iron core lamination apparatus for forming and laminating ribbon-shaped magnetic materials made of silicon copper plates, amorphous alloys, and the like.

The conventional wound core shown in the mt diagram is formed while being rolled up, but a part of the formed wound core must be cut when incorporating the sight lines, which has the drawback of making the work cumbersome.

This invention has been made in view of the above, and utilizes the softness of ribbon-shaped magnetic members to form and laminate the iron core into a predetermined shape. Embodiments of the invention will now be described with reference to the figures.

In Figure 2, (1) is a magnetic material made of a ribbon-shaped silicon copper plate or an amorphous alloy wound into a cylindrical shape, (2)
(3) is a cutting machine that cuts the magnetic material (1) supplied from the iron core supply device (2), (4b) is the supply machine (2) that supplies the magnetic material (1), ), set the magnetic material (1) supplied by the machine, travel a predetermined distance, hold the magnetic piece of a predetermined length cut by the cutting machine (3), and then travel to the right in the figure. , a running guide that runs to a predetermined position along a core mold (6) to be described later; (5) is a molding guide that molds and holds the cut magnetic piece;
) (4b) can be moved in the direction away from the core mold (6) by a distance through which the core (4b) can pass. (6) is a core type that maintains the inner dimensions of the cut magnetic piece.

Next, the operation will be explained. In Figure lh2, the initiation stage of cutting will be explained. First, the tip of the magnetic material (1) is cut into a cutting machine consisting of a shear etc. while automatically feeding the C magnetic material (1) through a feeding machine (2) consisting of a roll field 1 etc. (3), and the tip of the magnetic material (1) is placed on the traveling guide (4), which is composed of a traveling section and a core chuck section, which travels to the cutting dimension position in conjunction with the feeder (2). Set automatically.

Next, a method for continuous cutting will be explained.

After setting the dimensions of each magnetic piece in advance, the supply & (2) and running guide (4a) work together to continuously supply the magnetic material (1), and cut it with the running guide (4a). When the distance between the machines (3) reaches a predetermined distance, the feed machine (2), the traveling guide (4a), and the cutting machine [3] automatically start feeding the magnetic material (1) under automatic control. Stop and cut.

The cut magnetic piece is held by the traveling guide (4a) and moved to the core end position (6) to the preset core end position.
) and the forming guide (5) to reset the core end held. During this time, the waiting traveling guide (4b) automatically moves to the illustrated traveling guide (4a) position and transfers the end of the magnetic material +13 supplied by the feeder (2) to the iron core chuck. It is set at , and travels in conjunction with the feeder (2) to four predetermined positions of the cutting dimension.

Next, the travel guide (4a) is automatically moved to the position of the travel guide (4b) shown in 1 after being reversed by 180''.

A predetermined core structure is manufactured by continuously repeating such operations and laminating magnetic pieces.

The forming guide (5) has a mechanism for widening the distance from the core mold (6) when the traveling guide (4aX4b) passes through it, and a mechanism for maintaining core elevation forming and following dimensional changes in core lamination. It goes without saying that it also has a dimension adjustment mechanism between the forming guides (6) and can accommodate the dimensions of each core.

Moreover, it goes without saying that the travel locus of the travel guide can accommodate dimensional changes in the core lamination.

In other words, by numerically setting the core cutting dimensions and the core end position, the core end position can be automatically changed, and as shown in Figure 8, the upper core and lower core lap 1. is possible.

As described above, according to the present invention, since cutting, forming, and laminating can be performed simultaneously, a laminated iron core can be manufactured easily.
