Abstract

A pressure plate 12 has an upper surface 12a and a lower surface 12b. A blade die unit 16 for machining a workpiece by applying a pressure to a principal surface of the workpiece is arranged on the lower surface 12b. A face plate 24 has an upper surface 24a and a lower surface 24b, and is arranged such that the upper surface 24a faces the lower surface 12b with the blade die unit 16 interposed therebetween. An upper pressure roller 20 applies a pressure directed from the upper surface 12a side toward the lower surface 12b side of the pressure plate 12 to a portion of the upper surface 12a. A lower pressure roller 22 applies a pressure directed from the lower surface 24b side toward the upper surface 24a side of the face plate 24 to a portion of the lower surface 24b. A motor changes a portion that the upper pressure roller 20 pressurizes, and also, a portion that the lower pressure roller 22 pressurizes is changed such that the portion that the lower pressure roller 22 pressurizes is aligned with the portion that the upper pressure roller 20 pressurizes when viewed from a direction crossing the lower surface 24b.

Claims15

Dependent claims

A workpiece machining apparatus comprising:

a first plate-shaped member including one first principal surface and the other first principal surface on which a machining member for machining a sheet-shaped workpiece by applying a pressure to a principal surface of the workpiece is to be placed;
a second plate-shaped member including one second principal surface and the other second principal surface, the second plate-shaped member being flexible and being arranged such that the one second principal surface faces the other first principal surface with the machining member interposed therebetween;
a first pressure member for applying a first pressure directed from the one first principal surface side toward the other first principal surface side to a portion of the one first principal surface;
a second pressure member for applying a second pressure directed from the other second principal surface side toward the one second principal surface side to a portion of the other second principal surface;
a first changing unit for changing a portion that the first pressure member pressurizes;
a second changing unit for changing a portion that the second pressure member pressurizes such that the portion that the second pressure member pressurizes is aligned with the portion that the first pressure member pressurizes when viewed from a direction crossing the other second principal surface;
and
a detection unit configured to detect a position of the workpiece fed between the one second principal surface and the machining member,
wherein, on the basis of a result of detection by the detection unit, the first changing unit starts to change the portion that the first pressure member pressurizes.
