Further, under the same conditions, the first motor 121 has a rotational speed of 〇, and the output shaft 134 can still have an output of about 316 rpm by the flywheel 131. Therefore, as described above, it can be seen that 'the fly controller 131 is kept at a constant speed, and the rotation speed of the second motor 121 is adjusted by the controller unit 19, and the rotation speed of the output vehicle 134 can be adjusted to control the speed of the movement of the punch 20. . It is worth noting that the variable speed N in the above condition is about 522.45 ah (reverse), and the output speed 1 of the output 134 is 〇rpm 'punch at this time. 2〇 is in a static state of sorrow, that is to say, in the work of the punching machine, when the motor (1) t still maintains the speed of 800 rpm and the punch 2 〇 is in a stationary (fine i) state, it is not necessary. By braking, it is only necessary to adjust the rotational speed of the second motor 121 through the controller unit. Referring to Fig. 5 and Fig. 6, respectively, the speed curve of the second horse it 121 and the speed curve of the punch 2 () are performed for the punching machine respectively, wherein the dotted line & The motor speed is rotated, and the line b is the pre-1 speed curve of the second motor 丨21 when performing deep drawing processing according to the present invention, and the dotted line of the retort speed of FIG. 6 is deep-extended by the wide line 10 200838684 of FIG.
