Working principle:

when the die head 16 is installed, the guide insert 15 at the top of the die head 16 can be inserted into the guide slot 12, and the die head 16 is positioned through the guide insert 15;

then, the staff can rotate the fixing screw rod 20 clockwise, the fixing screw rod 20 drives the connecting rotating rod 23 to rotate, the connecting rotating rod 23 rotates in the bearing 19, and the connecting rotating rod 23 does not drive the second lifting plate 18 to rotate through the bearing 19;

the fixing screw rod 20 moves upwards through threads, the fixing screw rod 20 drives the connecting rotating rod 23 to move together, and the connecting rotating rod 23 drives the second lifting plate 18 to move through the bearing 19, so that the second lifting plate 18 drives the first lifting plate 10 to move upwards through the bottom rod 22;

at this time, the first lifting plate 10 drives the four groups of push-pull rods 11 to move together, so that the four groups of push-pull rods 11 are stressed and pull the four groups of L-shaped plates 14 to move, and the L-shaped plates 14 drive the clamping plates 25 to move together, so that the clamping plates 25 are tightly attached to the outer sides of the die heads 16, and the die heads 16 can be clamped by the four groups of clamping plates 25;

the fixed insert block 24 is inserted into the fixed slot 26 arranged on the die head 16, and the die head 16 is limited by the fixed insert block 24, so that the die head 16 can be prevented from moving continuously, and the die head 16 can be fixed firmly;

when the die head 16 needs to be replaced, a worker can rotate the fixing screw rod 20 anticlockwise, the fixing screw rod 20 drives the connecting rotating rod 23 to rotate, the connecting rotating rod 23 rotates in the bearing 19, and the connecting rotating rod 23 does not drive the second lifting plate 18 to rotate through the bearing 19;

the fixed screw rod 20 moves downwards through threads, the fixed screw rod 20 drives the connecting rotating rod 23 to move together, and the connecting rotating rod 23 drives the second lifting plate 18 to move through the bearing 19, so that the second lifting plate 18 drives the first lifting plate 10 to move downwards through the bottom rod 22;

at this time, the first lifting plate 10 drives the four groups of push-pull rods 11 to move together, so that the four groups of push-pull rods 11 are stressed and push the four groups of L-shaped plates 14 to move, and the L-shaped plates 14 drive the clamping plates 25 to move together, so that the clamping plates 25 are far away from the die head 16, and the fixed insert blocks 24 can be taken out from the inside of the fixed slot 26;

the operator can then remove the guide insert 15 from the inside of the die head 16, i.e., remove the die head 16 from the punch plate 4, and replace the die head 16 directly.
