DEVICE AND METHOD FOR MANUFACTURING A LAMINATED CORE

Claims

1. A device for producing a laminated core, in which core sheets having a given shape are formed by cutting from a steel sheet, and a given number of core sheets are laid and connected, comprising a cutting part that cuts out the core sheets from the steel sheet; an adhesive applying part that applies adhesive to the areas of the steel sheet corresponding to the core sheets; a stacking portion that stacks and connects the core sheets onto which the adhesive is applied to form a core sheet group; and a separating portion that is inserted into the spaces between core sheets adjacent to each other in a core sheet group to separate the laminated core from the core sheet group, wherein the laying portion comprises a plurality of pairs of lateral pressure application portions that apply lateral pressure to the core sheet group, wherein each pair of lateral pressure application portions faces each other with the core sheet group located therebetween, and at least one of the lateral pressure application parts is configured to perform the function of a separating part.

2. A device for producing a laminated core according to claim 1, in which each of the plurality of pairs of lateral pressure application parts comprises a brake block that is pressed against the lateral surface of a group of core sheets, the brake block is designed with the possibility of tilting when separating the laminated core from the group of core sheets so that the upper or lower corner in the direction of the height of the group of core sheets is introduced into the spaces between the core sheets.

3. A device for producing a laminated core according to claim 2, in which the brake block is designed such that the upper corner is embedded in the spaces between the sheets of the core, and the lower corner is inclined away from the group of sheets of the core.

4. A device for producing a laminated core according to claim 3, in which the brake block is supported with the possibility of rotation by a rotary shaft located above the central position of the brake block in the direction of the height of the group of core sheets.

5. A device for producing a laminated core according to any one of paragraphs 1-4, in which the cutting part changes the shape of the end of the core sheet in a position where the laminated core is separated from the group of core sheets.

6. A device for producing a laminated core according to any one of claims 1 to 4, wherein an adhesive is applied to the surface of a steel sheet, and an uncoated area where the adhesive is not applied is provided in the outer peripheral portion of the surface of sections of the steel sheet corresponding to the core sheets, and when a group of core sheets is formed in the stacking portion, the uncoated area forms a gap between the core sheets adjacent to each other in the group of core sheets, and a separating portion is inserted into the spaces between the core sheets through the gap formed by the uncoated area.

7. A method for manufacturing a laminated core, which includes manufacturing the laminated core using a manufacturing device according to any one of paragraphs 1-4.
