[0033]

As described above, the present invention is constructed as described above, and simultaneously moves the work held by the work holder in the X-axis direction and the Y-axis direction, thereby independently moving each of the punch holding split dies. Thus, a punch hole having a shape held by each of the punch holding divided molds can be formed in each of the punched areas partitioned by the punch with the punch pitch held by the punch holding divided mold. Also,
By interlocking the control of the work in the X-axis and Y-axis directions with the movement of the respective punch holding and splitting dies, it is also possible to perform high-density punching of holes of the same shape in each of the punching areas partitioned by the work. At the time of punching, the height position of the punch holder, which is the lower component of each punch holding and splitting mold, with respect to the die holding mold is adjustable, so that when a desired punching area is moved below the desired punch holding and splitting mold. The punch-holding split-type die holder, which interferes with the work holder, is positioned at a high height so as to be separated from the die holding die so that the work (movement of the work holder) is not hindered. The hole can be moved after securing a wide carry-in space, so that only the punch-holding split-type punch holder to be punched is brought close to the workpiece to perform punching. Therefore, for example, as in the case where a large work carry-in space in which the work holder can be moved is secured between all the punch holding and splitting type punch holders and the die holding die to perform punching, the punch holding and splitting type and the work are separated. A large gap is left between the gaps, causing a dance phenomenon (work rise due to the adhesive force with the punch when punching and dropping the work due to the stripper function of the punch holder) in the gap, and the impact causes punching. There is no adverse effect on accuracy. Also, with the punch holding divided mold that interferes with the work holder being separated from the work holder, another punch holding divided mold can be approached to the work within the range surrounded by the work holder. In addition to this, it is possible to effectively utilize a wide range of the work area surrounded by the work holder as the perforated area range. Also, the shape is different from the punch holding split type,
If a desired punch, such as a round punch, a rectangular punch, an elliptical punch, etc., is held, the section is performed by hitting the selected punch holding and splitting mold while moving the work in the X-axis direction and the Y-axis direction. A round punch hole, a rectangular punch hole, an elliptical punch hole, and the like can be punched for each desired area of the drilling area. Even when a round punch having a different diameter is held, the round punch hole is formed for each desired area of the partitioned punching area. Punch holes for each diameter can be punched, and a variety of drilling processes can be selected. The punch holding and splitting mold having a slender rectangular shape in a plan view does not increase in area because the punch holding mold is divided into a plurality of planes in a plan view. The occupation of the installation space is comparable. In addition, a plurality of punch holding divided mold groups that hold punches of the same shape at equal intervals according to shape are configured so that they can be disengaged and can be struck by the group via a striking drive source that can be controlled in the horizontal direction. When the workpiece is moved in the X-axis direction and the Y-axis direction, a plurality of punch holding and splitting dies are selectively driven by one driving drive source to form different shapes for each desired area of the drilling area. The punch holes are punched, and the equipment cost can be reduced. In addition, the means for releasing the connection between the driving drive source and each of the punch holding and splitting types is a vacuum suction or electromagnet capable of sucking and releasing, and the connection and disconnection of the driving drive source and each of the punch holding and splitting types can be performed. Easy to do.
