PCT No. PCT/SE87/00048 Sec. 371 Date Sep. 28, 1988 Sec. 102(e) Date Sep. 28, 1988 PCT Filed Feb. 3, 1987 PCT Pub. No. WO87/06165 PCT Pub. Date Oct. 22, 1987.Arrangement for the ejection of a pressed component from a press tool. The arrangement consists of a number of ejection pins distributed over the press surface tool. Each of the ejection pins is so arranged as to lie during the pressing operation with its tip no higher than on a level with the aforementioned press surface, and, in conjunction with the opening of the tool after a pressing operation has been completed, as to eject the component from the tool with its tip. A characteristic feature of the invention is that each ejection pin is operatively connected via a pistion rod to a hydraulic piston. The piston is capable of axial displacement in a hydraulic cylinder, which is filled with an incompressible fluid in space between the piston and an end wall of the cylinder. The space communicates via a duct with a drive unit for the ejection pin. |
