<p>An electromagnetic clutch for a safety protection device of a press machine comprises an upper case body (5) and a lower case body (6). An upper iron core (1) is disposed in the upper case body (5). The upper end of the upper iron core (1) passes out of the top surface of the upper case body (5). A coil (4) is sleeved on the upper iron core (1). A socket base (7) is disposed on a side wall of the upper case body (5). An aerial socket (8) connected to the coil (4) is disposed in the socket base (7). A T-shaped lower iron core (2) is disposed in the lower case body (6). The lower end of the lower iron core (2) passes out of the bottom surface of the lower case body (6). A pressure spring (3) is disposed between the T-shaped top end of the lower iron core (2) and the bottom surface of the lower case body (6). The pressure spring (3) is sleeved on the external surface of the lower iron core (2). Copper sheathing is omitted in the upper and lower case bodies of the electromagnetic clutch, thereby avoiding fixing the electromagnetic clutch to the body of the press machine, saving a plurality of mounting accessories, thereby reducing the cost of the product and facilitating the installation and maintenance of the product. When the upper and lower iron cores are bound, the electromagnetic clutch moves up and down as a whole, and when the upper and lower iron cores are separated, only the lower iron core moves downward, thereby prolonging the service life of the electromagnetic clutch.</p> |
