Kind Code:
A
Abstract:
To provide a punching apparatus that can suppress breakage of the apparatus and decrease of the apparatus life.SOLUTION: A punching apparatus includes a moving surface plate 1 and a fixed surface plate 2, a lifting/lowering transmission mechanism 4 for making the moving surface plate vertically move toward an opposed surface plate and a pressing motor, and a control unit for controlling the pressing motor. A die cutter 100 punches a sheet material S in a predetermined shape by a trimming die 8 mounted to the fixed surface plate 2 by the movement of the moving surface plate 1 toward fixed surface plate 2. In the die cutter, there are included a strain sensor 26 for measuring a deformation amount of a front frame 5 and a depth frame 6 deformed when pressing the moving surface plate 1 toward the fixed surface plate 2, and an operation panel for notifying that the measurement deformation amount measured by the strain sensor 26 reaches a deformation threshold value or more.SELECTED DRAWING: Figure 8
