  • Patent number: 7234337
    Abstract: A punch press that provides an arrangement of a motor and a crank mechanism so that the motor does not project far from the side of a frame. The punch press includes a servo motor, a ram which drives a press tool, a crank mechanism which converts a rotating motion transmitted to a crank shaft into an elevating and lowering operation of the ram, and a drive transmitting mechanism which transmits rotation of the servo motor to the crank shaft while reducing rotation speed. The servo motor is next to the crank mechanism and its rotating axis is parallel to the axis of the crank shaft. The drive transmitting mechanism includes servo motor side gears joined to respective output shafts of the servo motor. The servo motor side gears respectively engage, directly or via intermediate gears, with crank side gears joined to the crank shaft.

  • Patent number: 7028611
    Abstract: The present invention provides a motor driven link press which enables working with a heavy press load and also enables a working cycle time to be improved even when a motor with a relatively low output power is used and which can be properly controlled easily. A motor driven link press comprises a link mechanism 1 that converts a rotating operation into a linear operation and a ram 6 that elevates and lowers for press working on the basis of this linear operation. The link mechanism 1 comprises a crank member 2 having a crank shaft 3 and an eccentric shaft portion 4, a pivoting link 5, a connecting rod 7, and a restraining link 8. The pivoting link 5 has a first to third connecting portions P1 to P3 and is connected to the eccentric shaft portion 4 of the crank member 2 using the connecting portion P1. The connecting rod 7 is connected to the second connecting portion P2 and the ram 6.

  • Publication number: 20050040775
    Abstract: The present invention provides a punch press that enables the arrangement length of a motor and a crank mechanism to be reduced so that the motor can be installed without being projected far from a side of a frame, the punch press avoiding biasing the motor, which may act as a heat source, to reduce the magnitude of deformation resulting from a difference in thermal expansion between the right and left sides of the frame. A punch press includes a servo motor 2, a ram 3 which drives a press tool, and a crank mechanism 4 which converts a rotating motion transmitted to a crank shaft 6 into an elevating and lowering operation of the ram 3. The punch press is provided with a drive transmitting mechanism 5 which transmits rotation of the servo motor 2 to the crank shaft 6 while reducing a rotation speed. The servo motor 2 is placed by the side of the crank mechanism 4 so that its rotating axis 01 is parallel to the axis 0 of the crank shaft 6.
