Abstract
An apparatus for manufacturing a heat sealing-type rotational laminated core, includes an upper mold and a lower mold, and forming and stacking individual laminar members, the individual laminar members being formed by having a strip which is sequentially transferred on the upper portion of the lower mold undergone a piercing process and a blanking process by punches mounted on the upper mold.
Claims4
An apparatus for manufacturing a heat sealing-type rotational laminated core, comprising an upper mold (3) and a lower mold (4), and forming and stacking individual laminar members (101), the individual laminar members (101) being formed by having a strip (100A) which is sequentially transferred on an upper portion of the lower mold (4) undergone a piercing process and a blanking process by punches mounted on the upper mold (3), wherein the apparatus for manufacturing the laminated core further comprises:
- a squeeze ring (201) installed on a lower portion of a blanking die (11) for the blanking process;
- a heating means (202) installed on an outer portion of the squeeze ring (201);
- a rotating die (203) having the squeeze ring (201) and the heating means (202) installed therein to rotate by a predetermined pitch with the squeeze ring (201) and the heating means (202);
- and
- a ring-shaped rotating electrode (205) installed outside the rotating die (203),
- wherein the rotating electrode (205) is electrically connected to the heating means (202), so that the heating means (202) is supplied with electrical power when the rotating electrode (205) and a stationary electrode (206) installed outside the rotating electrode are electrically connected to each other.
