るとともに耐久性を高めることを目的とする。However, it has been found that, if the ball screw does not rotate at least one turn or more, the oil does not spread to the entire sliding portion, and the oil runs out and is easily worn. However, in this type of drilling machine, when the work to be drilled is thin and the vertical stroke of the punch ram, that is, the punch is small, the rotation of the ball screw may be less than one rotation. There is a problem that it is not possible to prevent running out of oil and not to maintain not only the durability of the drilling machine but also the drilling accuracy. SUMMARY OF THE INVENTION The present invention has been made in consideration of the above circumstances, and aims to prevent the punch driving device from running out of oil for a long period of time, maintain the drilling accuracy, and increase the durability.

The oil 28 is stored, and the screw portion 22 of the ball screw 20 is projected into the oil pan 27 so that the oil is immersed. The oil pan 27 has an inner diameter substantially equal to the diameter of the mounting hole 25, or a gap or groove 29 is formed on the bottom surface of the nut portion 21 as shown in the drawing, so that the oil pan 27 and the gap 26 in the mounting hole 25 are separated. Be in communication. Preferably, the oil 28 is supplied through a gap or a groove 29 to the gap 26 on the outer periphery of the screw portion 21.
Is stored so as to enter the predetermined height position.

摺動部分全体へのオイル浸透がより一層促進される。During the punching operation, the screw portion 22 of the ball screw 20 is rotated by the driving of the servo motor 8, and the punch 6 is moved up and down via the punch ram 4 by the forward / reverse rotation of less than one rotation. The hole is drilled in W, and the operation is repeated according to the movement of the work. During the drilling operation, the ball screw 20 repeats a small reciprocating movement of less than one rotation,
Since the oil 28 adheres to the lower end of the screw portion 22 that can protrude into the oil pan 27, the oil 28 adheres to the ball 23 of the ball screw through the lower end of the screw portion 22, and the balls 23, 23,. Due to the capillary action caused by the gap between the screw 23 and the nut portion 21 or the nut portion 21, the oil permeates the sliding portion of the ball screw 20 while sequentially transmitting to the adjacent balls. Also, as in the embodiment, the oil 28 is
21 Since it is stored up to the predetermined height position of the gap 26 on the outer circumference,
The initial oil permeation region is at a high position, and the oil permeation to the entire sliding portion of the ball screw 20 is further promoted.

がりによる弊害を除去し得るものである。The punching operation by the driving of the servo motor 8 will be described in more detail with reference to FIG. 2. The servo motor 8 is set in a double punching type in which the punch ram 4 is moved up and down twice at one punching point. . That is,
When the punch 6 pierces the workpiece W by the first descending of the punch ram 4 (FIG. 2A), the punch ram 4 is temporarily moved upward at a lower speed than the descending position to move the punch 6 upward (see FIG. b)) Then, the punch 6 is moved down again to the first lower limit position for the second time to lower the punch 6 ((c)).
Thereafter, the punch ram 4 moves up to return the punch 6 to the initial position ((d)). According to the double punching by the punch 6, even if the cutting waste 30 adheres to the punch 6 and rises during the punching (see FIG. 2B), the cutting waste 30 is moved by the die during the second upward movement of the punch 6. 5 or the hole edge of the work W is surely detached from the punch 6, and the adverse effect due to the floating of the cutting waste 30 can be eliminated.
