DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape-shaped multi-axial punching device.

[0002]

2. Description of the Related Art Conventionally, a tape-shaped multi-axial punching machine is a punching machine installed between a roll material while intermittently feeding a tape-shaped material by a feeding device intermittently and winding it up by a winding device. The required drilling is performed. The piercing machine of this multi-axis piercing apparatus uses a grid pattern piercing method or a gang pattern piercing method, and has a structure shown in FIGS. FIG. 5 shows that a stripper plate 74 is supported on a press ram B provided in the upper half u1 of a punching unit U having a U-shape in a side view which can be controlled in the X and Y axis directions so as to be vertically movable. A punch driving source 44 is mounted on the press ram B, and a punch holding die 64 is provided in communication with the driving drive source 44, and a die holding die 54 is supported on the lower half u2 of the punching unit U. The workpiece is controlled to move in the Y axis direction or the workpiece is similarly controlled to move in the X and Y axis directions. FIG. 6 shows a punch holding mold 64.
Upper frame 14 and lower frame 2 equipped with a driving drive 44
4 are connected by a horizontal frame 84 to assemble and form a rectangular main frame 4 ″, and guide rails L3, L3 are provided on opposing inner surfaces of the main frame 4 ″. A base frame 94 having a rectangular shape in a front view is slidably fitted, and a die holding mold 54 is installed on the upper surface of the base frame 94.
A stripper plate 74 disposed between the punch holding die 64 and the die holding die 54 is attached to the upper frame 14 of the main body frame 4 ", and the base frame 94 can be vertically moved with respect to the main body frame 4" by a ball screw mechanism. And this drilling machine is XY
The punch holding die 64 is driven by the driving of the driving source 44 while being controlled in the axial direction, and punching is performed by a punch.

In both the former shown in FIG. 5 and the latter shown in FIG. 6, the stripper plate 74 is pierced in a state in which the stripper plate 74 approaches the work corresponding to the thickness of the tape-like object (work) to be pierced. Processing is possible.
Therefore, for example, it is suitable for perforating a tape-like material in which, for example, ceramic green sheets or the like are easily spread when a pressing force is applied. However, since the former supports the punch holding die 64 and the die holding die 54 in the U-shaped punching unit U with an open front, when punching by the grid pattern punching method or the gang pattern punching method, There is a problem in that the upper half u1 of the punching unit U swings slightly due to the reaction force that strikes a large number of punches at a time, thereby deteriorating the punching accuracy. The latter is
Since the main frame 4 "receives the reaction force at the time of the drilling process by the drilling method, there is no problem that the drilling accuracy is deteriorated. However, since the main frame 4" and the base frame 94 are heavy, high-speed drilling is performed. However, there is a problem that productivity is poor.

The ball screw mechanism for the axis is driven to perform perforation at the same position in each area defined by each perforation area. The enlarged view in FIG. 2 shows the perforation pattern. When the drilling of the grid pattern drilling method in the drilling area is completed, the clamping by the upstream and downstream clampers 6, 6 is released, and the supply suction feeder 3, the pinch rollers 7, 7 are synchronized and virgin ( The tape-shaped material portion of the tape-shaped material portion which has not been subjected to the perforation processing is supplied to the working area of the punching die 4 to perform the perforation processing. On the other hand, every time the tape-shaped material W portion of the virgin (the tape-shaped material portion not subjected to the perforation processing) is supplied to the work area of the perforation mold 4, the tape after the perforation processing by the downstream cleaning roller mechanism 5 is used. Punched chips, dust and the like adhering to the part W are eliminated.

Incidentally, the grid pattern perforation processing method is as follows.
Each punch P is arranged at the same pitch as each punching processing area pitch. Each time the punching die 4 is controlled to move in the X and Y axis directions by a predetermined amount, the driving drive source 44 is driven to punch the punches. Drilling is performed at the same position in the processing area. Moreover, the tape-shaped multi-axial punching device of the present invention may be one that performs a punching process by a gang punching method.
