The first support column 11 and the second support column 12 are provided with an avoiding hole at the same horizontal height for the crankshaft 20 to pass through, and the avoiding hole is used for bearing the crankshaft 20. Wherein the first eccentric part 21 of the crankshaft 20 is disposed between the first support column 11 and the second support column 12, i.e. the whole stamping mechanism 40 is mounted in the frame 10, and the second eccentric part 22 is disposed on one side of the second support column 12 far away from the first support column 11, i.e. mounted outside the frame 10, so that the counting device and the stamping mechanism 40 do not interfere with each other when moving, and the counting device is mounted more simply and conveniently.
In one embodiment, as shown in fig. 1 and 2, the first eccentric portion 21 and the second eccentric portion 22 are symmetrically disposed along the axial direction of the crankshaft 20.
Optionally, that is to say, the shapes of the first eccentric portion 21 and the second eccentric portion 22 are the same, the crankshaft 20 is driven by the driving part 30 to rotate, when the first eccentric portion 21 rotates to the lower limit position, the punching mechanism 40 performs punching and cutting on the flitch, at this time, because the second eccentric portion 22 and the first eccentric portion 21 are axially and symmetrically arranged along the crankshaft 20, at this time, the second eccentric portion 22 also rotates to the lower limit position, and the first connecting rod 51 is driven to trigger the counter 52 once, so that the counting of the counter 52 and the punching of the punch 100 are performed simultaneously, and the data counted by the counter 52 is more accurate. Meanwhile, compared to the non-axial symmetry of the first and second eccentric portions 21 and 22 of the crankshaft 20, the machining of the crankshaft 20 is simpler, and the counter 52 is more conveniently installed.
In an embodiment, the counting assembly 50 further includes a mounting plate 53, the mounting plate 53 is mounted on a side of the second support column 12 away from the first support column 11, the counter 52 is mounted on the mounting plate 53, an end of the first connecting rod 51 away from the crankshaft 20 is an activation end 511, and when the activation end 511 is disposed at a very low point in the vertical direction, the activation end 511 abuts against the counter 52 to activate the counter 52.
Optionally, a plurality of bolt holes are formed in the side wall of the mounting plate 53, a plurality of mounting holes corresponding to the bolt holes one to one are formed in one side of the second support column 12 away from the first support column 11, and bolts pass through the mounting holes and the bolt holes one to fixedly mount the mounting plate 53 on the second support column 12.

The first link 51 may be a vertical rigid rod, and when the second eccentric portion 22 is also rotated to the lower limit position, the triggering end 511 of the first link 51 is also at the very low point in the vertical direction, and at this time, the triggering end 511 abuts against the counter 52, and the counter 52 counts once.
It should be noted that, in order to ensure the stability of the operation of the crankshaft 20, a supporting plate may be additionally provided at an end of the crankshaft away from the first supporting pillar 11.
Further, the mounting plate 53 has a groove 531 on a surface facing the trigger end 511, and the counter 52 is snap-fitted into the groove 531.
Wherein the lower end of the first connecting rod 51 is inserted into the groove 531, preferably, when the second eccentric portion 22 moves to the extreme high point by the driving member 30, the triggering end 511 of the first connecting rod 51 is still placed in the groove 531. That is, the first link 51 is always in the groove 531 during the movement, so as to provide a guiding function for the first link 51, and ensure that the trigger end 511 of the first link 51 can trigger the counter 52 accurately, so that the counting is more accurate.
In one embodiment, as shown in fig. 1 and 2, the mounting plate 53 further includes an elastic member 532, the elastic member 532 is mounted in the groove 531, one end of the elastic member 532 abuts against the groove bottom of the groove 531, and the other end of the elastic member 532 abuts against the counter 52.
