Heat Bonding Laminated Core Fabrication Device

Abstract

According to the present invention, an apparatus for manufacturing a heat adhesion type-laminated core comprises a mold device, a squeeze ring, an adhesion heating means and a cooling means. The mold device comprises an upper mold and a lower mold and forms a sheet of a laminar member in such a manner that a strip sequentially delivered from the upper part of the lower mold undergoes a piercing process and a blanking process by a punch mounted on the upper mold, the strip having a synthetic resin adhesion film deposited thereon or coated with a synthetic resin for adhesion. The squeeze ring is installed on the interior of the lower mold discharging a laminated core. The squeeze ring pushes a predetermined number of sheets of the laminar member that has undergone blanking in a blanking die to be laminated thereon. The adhesion heating means includes the squeeze ring. A magnetic field shielding means is installed in the outer periphery of the adhesion heating means. A protrusion forming device for separating a laminated core is further provided in the upper and lower molds between the piercing process and the blanking process.

Description

technical field [0001] The present invention relates to a bonded laminated core manufacturing device used as a laminated core of a stator or rotor of a motor or a generator, which is manufactured by laminating laminar members. More specifically, it relates to an adhesive laminated core production device capable of easily separating one core product by successively laminating sheet-like members. Background technique [0002] Generally, laminated cores obtained by stacking sheet-like parts obtained by punching and blanking laths are used as stators or rotors of motors or generators, and methods for producing laminated cores are widely known in the technical field to which the present invention pertains. as well known. [0003] Continuously form individual sheet-like parts by sequentially performing punching and punching for forming grooves, teeth, etc. on the strip supplied to the progressive die device, and finally stack the outer shape by a predetermined number of sheets A...

Problems solved by technology

[0008] However, in the above-mentioned conventional adhesive lamination method, in the process of applying the adhesive, the method of simply spraying the adhesive from the adhesive supply unit to the upper side or the side surface of the lath or using The way the adhesive drips from the hose connected to the lamination separation mold, so it takes a long time to apply the adhesive, which not only significantly reduces the productivity of the lamination core, but also cannot accurately apply the adhesive when it is needed Not only that, but there is also the possibility of adverse effects on molds, etc. due to the adhesive being scattered around

[0009] On the other hand, the laminated core produced by the above-mentioned prior art is produced in such a manner that a predetermined number of sheet-like members are embossed and laminated on the above-mentioned mold device to produce a predetermined number of laminated cores, and the laminated core is put into the lath. If the specified amount of glue reaches the required number of stamping sheets, the stacking counter connected to the punching device will instantly lift the stacking separation mold from the mold so that the glue cannot be put in, so as to make a stacked core with a specified number of sheets. , after the laminated cores whose number of sheets reaches the specified number are discharged, the mold device is suspended, and the next laminated core is produced by restarting the mold device, so the productivity of the laminated core is significantly reduced. In the latter, even if the glue is not applied to the counted The sheet-shaped parts also make the sheet-shaped parts continuously stacked on the punching die and discharged to the extrusion ring. The laminated sheet-shaped parts coated with glue and the sheet-shaped parts not coated with glue may be bonded to each other by glue, resulting in It is difficult to obtain laminated cores with a specified number of sheets. Not only that, but in the production of bonded laminated cores so far, there is no technology to bond laminated cores and discharge them continuously in a specified number of sheets.
