Abstract

The Thomson blade mold is generally used for the pushing shear of the corrugated cardboard. This Thomson blade mold was mounted on a precise press of the cam-toggle type newly developed and the pushing shear of the materials such as a PET, acrylic fiber and bakélite board was performed. The shearing load of pushing shear was measured and the shape of cross-section after the pushing shear was observed using a microscope. In the case of the pushing shear on the Thomson blade mold made of plywood used so far, it was sheared with a big breaking, and the cracks occur from the corner parts in the shearing of the acrylic fiber and the bakélite board. In this report, the steel-made Thomson blade mold of the replacement blade method to fix the Thomson blade with the bolt was newly designed, and the shearing method was changed. A shearing method of conventional Thomson blade mold made of plywood is a batch shearing method of only a shearing from a top. On the other hand, a shearing method of the steel-made Thomson blade mold is a top-and-bottom shearing method which sheared from top-and-bottom both directions. The influences of the difference of the shearing method on the shearing load and the shape of cross-section after the pushing shear were investigated.
