Title:
CORE MANUFACTURING APPARATUS AND CORE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/074938
Kind Code:
A1
Abstract:
Disclosed are a core manufacturing apparatus and a core manufacturing method by which a laminated core is formed by integrating a plurality of laminar members using a bonding method. The core manufacturing apparatus according to the present invention comprises: a laminator having a lamination hole and including a first heater, wherein the lamination hole is formed passing through vertically in order to pass the laminar members therethrough in a laminated state, and the first heater heats the laminar members, passing through the lamination hole, from the outside of the laminar members so that the laminar members are integrated by adhesive present at the interfaces between the laminar members; a core support capable of ascending and descending and provided below the lamination hole in order to support the laminated core discharged from the lamination hole; and a second heater which can enter the lamination hole via the lower end of the lamination hole so as to heat the laminar members from the inside of the laminar members, and can move up and down by passing through the core support. According to the present invention, the laminar members are heated from the outside and inside, and thus the adhesive can be uniformly cured, and interlayer bonding between the laminar members can occur stably.
