Tool for wire forming
A tool for wire forming is provided. The tool for wire forming may include a first anvil having a first chamber. The tool for wire forming further includes a second anvil having a second chamber. The tool for wire forming further includes a mandrel having a first portion disposed in the first chamber, a second portion disposed in the second chamber, and a third portion in between the first portion and the second portion. The third portion may include a recess configured to receive a wire. The second anvil may be configured to be actuated from an open position to a closed position to transform the wire into a formed wire.
1 . A tool for producing a formed wire, the tool comprising:
a first anvil comprising a first chamber;
a second anvil comprising a second chamber; and
a mandrel having a cylindrical shape, wherein the mandrel has a first portion disposed in the first chamber, a second portion disposed in the second chamber, and a third portion in between the first portion and the second portion, wherein the third portion comprises a recess configured to receive a wire, wherein the recess is in the third portion is cylindrical in shape and oriented perpendicular to a central axis of the cylindrical shape of the mandrel, wherein the second anvil is configured to be actuated from an open position to a closed position to transform the wire received into the recess into the formed wire, and wherein to actuate the second anvil from the open position to the closed position includes:
rotating the second anvil with respect to the first anvil and the mandrel; and
after rotating the second anvil, pushing the second anvil towards the first anvil and over at least a portion of the third portion of the mandrel.
2 . The tool of claim 1 , further comprising:
a plate fixed to the first anvil and comprising a stopper proximate the third portion of the mandrel.
3 . The tool of claim 2 , wherein the second anvil is configured to be rotated from a first position to a second position, wherein the second anvil is in contact with the stopper when in the second position.
4 . The tool of claim 3 , wherein the second anvil is configured to be rotated from the first position to the second position to transform the wire into a curved wire.
5 . The tool of claim 4 , wherein the second anvil is configured to be pushed to towards the first anvil to transform the curved wire into the formed wire.
6 . The tool of claim 1 , wherein the formed wire comprises a u-shaped portion and an elbow-shaped portion.
7 . The tool of claim 4 , wherein the curved wire comprises a u-shaped portion.
8 . A method for producing a formed wire, the method comprising:
placing a wire into a recess of a mandrel, wherein the mandrel has a cylindrical shape, wherein the mandrel has a first portion disposed in a first chamber of a first anvil, a second portion disposed in a second chamber of a second anvil, and a third portion in between the first portion and the second portion, wherein the recess is in the third portion is cylindrical in shape and oriented perpendicular to a central axis of the cylindrical shape of the mandrel;
actuating the second anvil from an open position to a closed position to transform the wire into the formed wire by:
rotating the second anvil with respect to the first anvil from a first position to a second position to transform the wire into a curved wire; and
pushing, after rotating the second anvil, the second anvil towards the first anvil and over at least a portion of third portion of the mandrel, to transform the curved wire into the formed wire.
9 . The method of claim 8 , further comprising:
retracting the second anvil away from the first anvil; and
removing the formed wire from the recess of the mandrel.
10 . The method of claim 8 , wherein the second anvil is in contact with a stopper when in the second position.
11 . The method of claim 8 , wherein the formed wire comprises a u-shaped portion and an elbow-shaped portion.
