block 66 to push the two clamp plates 69 to rotate and open, when the push block 62 drives the slide rod 65 to move to the bottom, the clamp plates 69 can rotate to the maximum and clamp the inner wall of the upper die 8, meanwhile, the clamp plates 69 can push the clamp plates 68 to move downwards, the clamp plates 68 can drive the supporting springs 67 to contract, and when one of the third belt pulley 316 or the fourth belt pulley 317 fixed in advance is arranged on the upper die 8 or the lower die 9, overload protection can be realized, thereby prevent to go up mould 8 or lower mould 9 and continue to press from both sides tightly, lead to anchor clamps and mould to all damage, and then increase the maintenance cost, can drive the swash plate 75 when fixed plate 61 moves down and move down, the swash plate 75 moves down and can promote connecting rod 73 anticlockwise rotation about 90 degrees, connecting rod 73 drives mounting panel 74 anticlockwise rotation about 90 degrees, the contained angle of swash plate 75 and connecting rod 73 here is 45 degrees, and the contact point is for leaning on the back department, make the swash plate 75 can promote connecting rod 73 and rotate by a wide margin, it is little to prevent rotation angle, lead to the mould to crush it, and then increase the maintenance cost, can install sucking disc or collecting box on mounting panel 74 and can realize carrying out the material loading or receiving to the mould after the punching press at every turn automatically, thereby need not the manual material loading or receiving of workman, further reduced workman's intensity of labour.
