Description

  The present invention relates to a punch press machine, and more particularly, to a punch press machine capable of eliminating punch / die misalignment and improving work quality and machining efficiency.

  Conventionally, as a device for drilling various forms of holes in a sheet metal part having a planar shape or a three-dimensional shape such as an automobile part, as shown in FIG. As shown in FIG. 6, a punch press machine in which the upper and lower rotary tables 200 and 300 are arranged in the punch / die storage part (C-shaped notch part) 110 and the punch unit 220 and the die unit 320 are switched by the upper and lower rotary tables 200 and 300. (B) A punch 600 / die 700 is disposed in a punch / die storage portion (C-shaped notch portion) 510 of the C-shaped frame 500 in a side view, and the punch 600 / die 700 is replaced by a robot or the like. A press is known. In the figure, reference numerals 120 and 520 denote pressure presses, 130 and 530 denote die receivers, 230 and 330 denote rotary motors, and 400 and 800 denote sheet metal parts.

  In such punch press machines (A) and (B), the device can be shared by switching the punch and die, but if the mechanical strength of the C-shaped frames 100 and 500 is weak, Since the pressurizing force and strength required for drilling change, the frames 100 and 500 are deformed as indicated by broken lines in FIG. 6, for example, and the punch / die is misaligned due to slippage of the punch tip. For this reason, there has been a problem that drilling cannot be performed, and even if drilling can be performed, the processing accuracy varies and the processing tool is damaged.

  For this reason, in order to ensure processing accuracy with the same punch press machine, a more robust frame is required, and the frame itself needs to have a robust structure. For example, the frame is formed of a metal material such as iron. However, when the frame itself has a robust structure, the weight of the punch press machine is increased overall, and the occupied space increases.
