[0054] The working principle of the utility model is:

[0055] When the utility model works, the punch and the high-speed cam type secondary dimension feeding mechanical hand 2 are started at the same time, the high-speed cam type secondary dimension feeding mechanical hand 2 transports workpieces to the front according to each stamping station, the motor driving rotating shaft 14 of the punch body 1 rotates, the rotating shaft 14 drives the upper table 13 to descend first and then ascend, the upper table 13 drives the upper die 11 and the cylinder to descend, the upper die 11 and the lower die 12 fold up and down, the cylinder descending drives the crank 47 to rotate downwards (the cylinder rod of the cylinder does not elongate), the crank 47 rotating downwards drives the transmission rotating shaft 46 to rotate forwards, the transmission rotating shaft 46 rotating forwards drives the left-right cylindrical cams 48 and 49 to rotate forwards, the left-right cam grooves 420 of the two left-right cylindrical cams 48 and 49 drive the two left-right translation seats 410 and 411 to move in opposite directions respectively, the two front-rear translation seats 412 and 413 also move in opposite directions, the left-right cam groove 420 drives the left-right driven wheels 416 to move to the farthest profile points of the left-right cam groove 420, the two front-rear translation seats 412 and 413 drive the first arm 21 and the second arm 22 to move in opposite directions respectively, the working principle of the second arm opening-closing driving mechanism 42 is same with the working principle of the first arm opening-closing driving mechanism 41, and the description is not repeated here, finally the mechanical hand 20 is opened, the first clamping jaw 23 and the second clamping jaw 24 loosen the workpiece, and at the same time, the upper die 11 descends and stamps the multiple workpieces on the lower die 12.

[0056] When the upper die 11 is punched, the rotating shaft 14 drives the front and rear cylindrical cams 31 to rotate through the transmission shaft 16, the first pulley 35, the transmission belt 37, and the second pulley 36, the front and rear cam grooves 33 drive the front and rear driven wheels 34 to move to the nearest contour points of the front and rear cam grooves 33, the rotation of the front and rear cylindrical cams 31 drives the front and rear translation plates 32 to retreat, the front and rear translation plates 32 drive the two front and rear translation seats 412 and 413 to retreat, thereby driving the mechanical hand 20 to retreat, and the first clamping jaw 23 and the second clamping jaw 24 move backward to the vicinity of the previous punching station. Since the track of the front and rear cam grooves 33 can be set according to requirements, when the first clamping jaw 23 and the second clamping jaw 24 just release the workpiece, a certain section of the track of the front and rear cam grooves 33 does not drive the front and rear driven wheels 34 to slide forward and backward, thereby not driving the first clamping jaw 23 and the second clamping jaw 24 to slide forward and backward, so as to ensure that the first clamping jaw 23 and the second clamping jaw 24 accurately place the workpiece on the punching station.

[0057] After the upper die 11 punches a plurality of workpieces, the motor of the punch body 1 continues to drive the rotating shaft 14 to rotate, the rotating shaft 14 drives the upper table plate 13 to rise, the elastic floating material ejector pin in the lower die 12 lifts the workpiece out of the die groove, facilitating the clamping jaw to grab, the upper table plate 13 drives the upper die 11 and the air cylinder to rise, the air cylinder drives the crank 47 to rotate upward (the air cylinder rod of the air cylinder does not elongate), the rotation of the crank 47 drives the transmission rotating shaft 46 to rotate reversely, the transmission rotating shaft 46 drives the left and right cylindrical cams 48 and 49 to rotate reversely, the left and right cam grooves 420 of the two left and right cylindrical cams 48 and 49 drive the two left and right translation seats 410 and 411 to move towards each other, and the two front and rear translation seats 412 and 413 also move towards each other, the left and right cam grooves 420 drive the left and right driven wheels 416 to move to the nearest contour points of the left and right cam grooves 420, the two front and rear translation seats 412 and 413 drive the first arm 21 and the second arm 22 to move towards each other, and the first clamping jaw 23 and the second clamping jaw 24 clamp the workpiece at the previous station.

[0058] At the same time, the rotation of the rotating shaft 14 drives the front and rear cylindrical cams 31 to rotate, the front and rear cam grooves 33 drive the front and rear driven wheels 34 to move to the farthest contour points of the front and rear cam grooves 33, the rotation of the front and rear cylindrical cams 31 drives the front and rear translation plates 32 to advance, the front and rear translation plates 32 drive the two front and rear translation seats 412 and 413 to advance, thereby driving the first arm 21 and the second arm 22 clamping the workpiece to slide forward to the previous station. Since the track of the front and rear cam grooves 33 can be set according to requirements, when the first clamping jaw 23 and the second clamping jaw 24 just clamp the workpiece, a certain section of the track of the front and rear cam grooves 33 does not drive the front and rear driven wheels 34 to slide forward and backward, thereby not driving the first clamping jaw 23 and the second clamping jaw 24 to slide forward and backward, so as to ensure that the first clamping jaw 23 and the second clamping jaw 24 accurately, firmly clamp the workpiece.

[0059] The multiple groups of clamping claws can simultaneously continuously and synchronously convey multiple workpieces forward, so that the punch can continuously punch the multiple workpieces at the same time, and therefore the workpiece transmission efficiency and production efficiency are high, and full-automatic continuous high-speed production can be realized. For example, the first group of clamping claws grasps the workpiece on the first punching station and conveys it forward to the second punching station on the lower die 12, at the same time, the second group of clamping claws grasps the punched workpiece on the second punching station to the third punching station on the lower die 12, the rear clamping claws also synchronously feed according to the above mode, finally, the last group of clamping claws clamps away the workpiece on the last punching station on the lower die 12, after all the clamping claws complete feeding once, they are automatically reset, and then the above step is repeated to grasp the workpiece on the previous punching station to the next punching station.
