奥地利专利№316278(申请日期1971年12月30日,公布1974年7月10日):本专利结构的剪板机的刀架5绕轴6摆动(见图),机器上装有带辊子11的平板12,用来支承在上下刀片7和3之间沿工作台送进的板料8。平板12可以消除薄板的下垂和厚板的倾翻,它铰接在轴10上,轴10固定在刀架5两端的支座9上。平板12的另一边支承在辊子20上,辊子20装在绕轴13摆动的空心轴14的杠轩19上。在剪下板料后,油缸18的活塞杆16拉动轴14上的杠杆15,使杠杆19落下,平板12倾斜,剪断的毛坯沿着辊子11落到料箱22中去。可用较轻的平板12减轻刀架的负载。适用于剪切长度较大的剪板机:
Austrian Patent No.316278 (application date December 30, 1971, published July 10, 1974): The knife holder 5 of the plate shearer of the present patent structure oscillates about a shaft 6 (see the figure) The plate 12 supports the sheet material 8 fed along the table between the upper and lower blades 7 and 3. The flat plate 12 can eliminate the sagging of the thin plate and the tilting of the thick plate. It is hinged on the shaft 10, and the shaft 10 is fixed on the support 9 at both ends of the knife holder 5. The other side of the plate 12 is supported on a roller 20 which is mounted on a bar 19 of a hollow shaft 14 which pivots about a shaft 13. After shearing the sheet, the piston rod 16 of the cylinder 18 pulls the lever 15 on the shaft 14, dropping the lever 19 and the plate 12 slanting, so that the sheared blank falls along the roller 11 into the magazine 22. Lighter plate 12 can be used to reduce the load on the tool holder. Suitable for shearing machine with larger shearing length:
