Title:
ELECTROMAGNETIC DEVICE FOR ATTRACTING CUTTING DIE OF BLANKING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/040694
Kind Code:
A1
Abstract:
An electromagnetic device for attracting a cutting die of a blanking apparatus comprises a substrate (1) for securing and mounting an electronic attraction disc (2). Multiple installation positions are uniformly arranged at a frontal surface of the substrate (1). The electronic attraction disc (2) is installed at each of the installation positions. Connection wires of the respective electronic attraction discs (2) are located at a back surface of the substrate and connected to a power supply after wiring. Each electronic attraction disc (2) realizes a magnetic force to attract a cutting die by controlling connection and disconnection of a circuit by means of an external switch. The electromagnetic device for attracting a cutting die uses multiple electromagnets controllable by turning on or off a current as magnetic mediums, such that generation or elimination of magnetism is entirely controlled by turning on or off a power supply, thereby ensuring reliable attraction of a cutting die, and preventing existence of residual adhesive. When a cutting die is to be replaced, a power circuit can be disconnected. After completion of the replacement process, the power circuit can be connected to realize real-time attraction of the cutting die.
