Detailed Description

In order to make the objects, contents and advantages of the present invention clearer, the following description will be made in further detail with respect to the embodiments of the present invention.

The utility model provides a pair of general vertical book ear ring bending die, characterized by: the device comprises an upper die holder 1, a guide block I2, a punching handle 4, a pre-bending upper die 5, a ring rolling upper die 7, a lower die holder 10, a guide block II 11, a stop block 13, an air cushion rod 14, a ring rolling lower die 17, a pre-bending lower die 19 and a positioner 20;

the punch handle 4 is connected with the center of the top end of the upper die holder 1 through a screw II 6, and the punch handle 4 is connected with a machine tool sliding block;

the pre-bending upper die 5 is fixed on the lower end face of the upper die holder 1 by a screw I3; the pre-bending lower die is fixed on the upper end surface of the lower die base 10 by a screw VI 22 and a pin I18;

the guide block I2 and the positioner 20 are fixed in a groove of the pre-bending lower die through a screw V21, the guide block plays a role in guiding the pre-bending upper die 5, the positioner 20 performs initial positioning on a pre-bending part, and the pre-bending upper die 5 is matched with the groove of the pre-bending lower die to perform pre-bending on the part; the pre-bending upper die 5 is matched with the guide block I2.

The upper coil ring die 7 is fixed on the lower end face of the upper die holder by a screw VIII; the lower coiling ring die 17 and the guide block II 11 are respectively fixed on the lower die base 10 by a screw IV 16 and a screw III 12;

the stop block 13 is connected with an air cushion rod 14, is arranged on the lower die holder and can move up and down relative to the lower die holder; the check block 13 is positioned between the lower coil ring die 17 and the guide block II 11 to form movable fit, the upper coil ring die 7 is matched with the lower coil ring die 17 to form the shape of a coil ring of a part after being closed, and the top of the check block 13 is always contacted with the lower end surface of the lower coil ring die 17 to push an elastic air cushion of a machine tool to move downwards to play a role in buffering; and a certain gap is reserved between the upper coil ring mould 7 and the side wall of the lower coil ring mould 17 and used for accommodating the straight line section of the part.
