SHEARING METHOD OF METAL STRIP WELDED END AND ITS DEVICE

摘要

PURPOSE:To make a device small-sized and improve the cutting precision by connecting the upper end and lower end of a C-type frame with an arm holder at a shearing position. CONSTITUTION:A near-L-type bent section 16 is formed at the tip of both arms A, B. This bent section 16 enters into a near-U-type groove 17 formed inside a holder 15 from the vertical direction of the paper surface when a C-type frame 5 has reached its shearing position so that the arms A, B are coupled with the arm holder 15. The arm holder 15 is supported symmetrically up and down by a holder support member 19 provided on the line side. Accordingly, the overall device is made small-sized and a large gate-type frame is made unnecessary.
