Abstract
An extrusion press die-slide device is equipped with: a fixed frame; a moveable frame that can move linearly but which is supported by the fixed frame in a non-rotatable manner; a first motion conversion mechanism that converts input rotational motion to linear motion and outputs the same to cause the moveable frame to move linearly with respect to the fixed frame; and a second motion conversion mechanism attached to the moveable frame and equipped with a pusher to impart a pressing force to a die of the extrusion press, and which transmits the input rotational motion to the first motion conversion mechanism and converts the input rotational motion to linear motion and outputs the same to cause the pusher to move linearly with respect to the moveable frame.
Claims9
A die-slide device of an extrusion press comprising:
- a fixed frame;
- a moving frame supported by the fixed frame and adapted to linearly move with respect to the fixed frame but to be unable to rotate;
- a first motion converting mechanism that converts input rotational motion to linear motion and outputs the same to move the moving frame linearly with respect to the fixed frame;
- and
- a second motion converting mechanism having a pusher that pushes against a die of the extrusion press and attached to the moving frame, the second motion converting mechanism transmitting input rotational motion to the first motion converting mechanism and moving the pusher linearly with respect to the moving frame by converting the input rotational motion to linear motion and outputting the same.
