PURPOSE:To prevent the excessive reaction force and miniaturize the device by connecting between the turning center of york with a tie rod and making the constitution to receive the reaction fore at pressing between the turning center rotation of york. CONSTITUTION:When a material 24 is pressed, an eccentric shaft 2 rotates in the center of a rotary shaft center by driving a driving device 1. Connecting rods 4a, 4b are moved to the right and left direction respectively because the center of rotary shafts O1, O2 is shifted at 180 deg. putting in a rotary shaft center O and are repeated with reciprocating motion. As yorks 8a, 8b turn in the center of pins 7a, 7b of support block 6a, 6b, slides 11a, 11b are moved approachingly and separatingly in the right and left direction by the guide of guide materials 10a, 10b. Therefore, a material 24 is pressed by tools 23a, 23b. The reaction force at pressing acts to a tie rod 16 as a tensile force, at the same time, acts to connecting rods 4a, 4b as a tensile force prevent the excessive moment on a frame 3. |
