The application method of the invention is as follows:

in the use process, the workpiece is drawn out to the right side through a manual mode after being punched in the punching seat 2, when the punched hole corresponds to the stop block 124, the stop block 124 falls into the punching hole under the action of gravity, at the moment, the workpiece is pushed reversely, at the moment, one side of the bottom of the stop block 124, which is not provided with an inclined plane, is contacted with the punching hole, so that the movement of the workpiece is blocked, at the moment, the hydraulic press 3 is started manually, a second hole is punched on the workpiece, at the moment, the distance between the two punching holes is the distance between the output shaft of the hydraulic press 3 and the stop device 12, so that the required punching distance is obtained, compared with the traditional simple punching equipment which needs manual or auxiliary measurement, the method is simpler and higher in precision, and low in cost, when the punching distance needs to be regulated, the positions of the stop device 12 and the trigger device 13 only need to be regulated, to facilitate operation, when a third hole needs to be punched, the workpiece is continuously drawn out, the first punched hole corresponds to the rectangular clamping block 134, the second punched hole corresponds to the stop block 124, the workpiece is pushed in the reverse direction, since the first punched hole contacts with one side of the rectangular clamping block 134, which is not provided with an inclined plane, during the reverse pushing and moving process of the workpiece, the reset spring 1303 is pressed to enable the triggers 1302 to contact each other, and since the stop block 124 and the rectangular clamping block 134 are in the state of corresponding to the punched holes and falling, the stop block 124 in the other side stop device 12 is in the state of not falling due to the corresponding punched holes, so that the conductor bar 10 is kept in contact with and in the electrified state with the trigger block ii 136 and the trigger block i 126 at the moment, and meanwhile the controller 9 controls the hydraulic machine 3 to punch the workpiece, the subsequent operation no longer needs manual operation, the operation of the hydraulic press 3 needs an operator to apply external force, the hydraulic press 3 is activated to punch holes by keeping a certain acting force with the stop device 12 and the trigger device 13, the workpiece is tightly contacted with the stop device 12 and the trigger device 13 during punching, and the stop device 12 and the trigger device 13 are simultaneously contacted with the workpiece, so that the acting force can be shared between the stop device 12 and the trigger device 13 during punching.

When the device punches square holes, when one side of the arc-shaped clamping block 139 cross section is the cambered surface and the punched hole contact, the falling of the rectangular clamping block 134 is not hindered, so that the square punched hole is finally contacted with one side of the rectangular clamping block 134, which is not provided with an inclined surface, when the device punches round holes, the protruding edges and corners of the rectangular clamping block 134 in the falling process of the rectangular clamping block 134 can be directly contacted with a workpiece, so that the rectangular clamping block 134 is prevented from continuously falling, one side of the arc-shaped clamping block 139 cross section is contacted with the round punched hole, so that the contact between one side of the arc-shaped clamping block 139 cross section which is the cambered surface and the round punched hole is more sufficient and the force distribution is more balanced, when the diameter of the round punched hole is changed, a round through hole is formed in the bottom of the sleeve frame 138, the arc-shaped clamping block 139 is sleeved inside the round through hole, the diameter of the arc-shaped clamping block 139 is always matched with the diameter of the punched hole, and the position of the arc-shaped clamping block 139 can be adjusted through the rotating adjusting bolt 137, and one side of the inclined surface of the arc-shaped clamping block 139 and one side of the rectangular clamping block 134 can always form a complete inclined surface.

The workpiece contacted by the stop device 12 positioned at the left side of the punching seat 2 is positioned on an unperforated rotary table, so that the stop block 124 in the stop device 12 is always in a lifted state, at the moment, the reserved length of the tail end of the workpiece can be realized by setting the distance between the stop device 12 and the output shaft of the hydraulic press 3, when the workpiece is punched, the residual length of the workpiece is smaller than the distance between the stop device 12 positioned at the left side of the punching seat 2 and the output shaft of the hydraulic press 3, so that the stop block 124 in the stop device 12 loses the support of the workpiece and falls, the trigger block I126 in the stop device 12 is contacted with the conductor rod 10, and at the moment, the conductor rod 10 is always in an open circuit when the conductor rod 10 is contacted with the trigger block I126 positioned at the left side of the punching seat 2, so that the hydraulic press 3 can not perform punching operation through the control of the controller 9 any more, and the confirmation is needed manually.
