Abstract: A punching machine includes a body frame having a table to support a workpiece. First and second work movement positioning apparatuses are mounted at both sides to move and position the workpiece in a direction of axis X. A work head is mounted on the body frame and has a ram and a tool. The work head moves on the body frame in a direction of axis Y, which is perpendicular to axis X. The first and second work movement positioning apparatuses are arranged in series in the direction of axis X. The workpiece is clamped by the first positioning apparatus, moved in the direction of axis X, punched, clamped by the second positioning apparatus, unclamped by the first positioning apparatus, and moved further in the direction of axis X.

Abstract: The present invention relates to shearing machine in which the upper shearing blade can be easily adjusted and positioned. The upper blade is held on a pivotal plate member which is pivotally held on a ram by means of a hinge to be rotated to adjust of the position of the upper blades. In addition, a hold down member is provided for holding a work-sheet. The hold down member is arranged to be urged by a toggle joint to hold the work-sheet at a reduced speed with an increased force after coming into contact with the work-sheet. A scrap removal member is also included in the shearing machine such that scraps can be easily removed without mingling them with the finished sheets. The scrap removal member removes scrap without idle time between feeding the work-sheets to be sheared. The shearing machine is so arranged that scraps are taken away directly to a scrap box as soon as the work-sheet has been complete sheared into its finished product.
