Abstract
A slew-actuated stamping station includes an expandable core configured to apply radially outward pressure to a radially inward facing surface of a radial wall, and at least one slew-actuated punch for piercing, along a radially inward direction, a respective hole in the radial wall. A method for piercing a radial wall includes simultaneously (a) applying radially outward pressure against a radially inward facing surface of the radial wall, and (b) driving a slew to actuate at least one punch to pierce, along direction opposite the radially outward pressure, at least one hole in the radial wall. A method for forming an object, having a radial wall with holes, includes forming a ring with a radial wall, and piercing at least one hole in the radial wall with at least one slew-actuated punch.
Claims20
A method, comprising:
- applying radially outward pressure against a radially inward facing surface of a radial wall;
- and
- rotating a drive ring to shift an azimuthal position of a distal joint that is located where a lever connects to the drive ring;
- pivoting, in response to said rotating the drive ring, the lever about the distal joint;
- pivoting, in response to said pivoting the lever about the distal joint, the lever about a proximate joint that is located where the lever connects to a punch;
- guiding, in response to said pivoting the lever about the proximate joint, the punch radially inward toward the radial wall;
- and
- piercing, in response to said guiding and with the punch, a hole in the radial wall.
A method, comprising:
- applying radially outward pressure against a radially inward facing surface of a radial wall;
- and
- rotating a drive ring to (i) shift a first azimuthal position of a first distal joint that is located where a first lever connects to the drive ring and (ii) shift a second azimuthal position of a second distal joint that is located where a second lever connects to the drive ring;
- pivoting, in response to said rotating the drive ring, the first lever about the first distal joint;
- pivoting, in response to said rotating the drive ring, the second lever about the second distal joint;
- pivoting, in response to said pivoting the first lever about the first distal joint, the first lever about a first proximate joint that is located where the first lever connects to a first punch;
- pivoting, in response to said pivoting the second lever about the second distal joint, the second lever about a second proximate joint that is located where the second lever connects to a second punch;
- guiding, in response to said pivoting the first lever about the first proximate joint, the first punch radially inward toward the radial wall;
- guiding, in response to said pivoting the second lever about the second proximate joint, the second punch radially inward toward the radial wall;
- piercing, in response to said guiding the first punch, a first hole in the radial wall with the first punch;
- and
- piercing, in response to said guiding the second punch, a second hole in the radial wall with the second punch .
