Abstract
Driving systems for tools used with metal-fabricating presses or other machines, whereby planetary gears are used in the systems, and whereby the driving systems can be constructed for use with particular tooling, such as tapping tools, and complementary systems can be exemplarily configured for use with such driving systems. The driving systems can enable enhanced tool output as compared to conventional driving mechanisms, while also enabling variable disassembly and configuration of the systems relative to the intended machining operations.
Claims30
A driving unit for tooling usable with metal-fabricating presses or other machines comprising:
- a first portion and a second portion operably linked to the first portion so as to be movable relative to the first portion, whereby in event of a downward force contacting the first portion and contact being made between the second portion and a rigid structure, upward movement of the second portion results relative to the first portion;
- an assembly for tooling;
- a gearing configuration operably linked to the assembly for tooling;
- a singular helix drive that operably links the gearing configuration to one of the first portion or the second portion;
- whereby in event of the upward movement of the second portion, a corresponding transfer of force results and comprises input linear force being transferred to output rotational force, whereby said transfer of force results from the linkage and corresponding movements of the one of the first portion or the second portion and the helix drive relative to each other;
- wherein the helix drive is rotatable relative to the second portion, whereby rotation of the helix drive is triggered by the upward movement of the second portion;
- wherein the assembly for tooling is situated below and in line with the helix drive.

A driving unit for tooling usable with metal-fabricating presses or other machines comprising:
- a first portion and a second portion operably linked to the first portion so as to be movable relative to the first portion, whereby in event of a downward force contacting the first portion and contact being made between the second portion and a rigid structure, upward movement of the second portion results relative to the first portion;
- an assembly for tooling;
- a gearing configuration operably linked to the assembly for tooling;
- a helix drive that operably links the gearing configuration to one of the first portion or the second portion;
- whereby in event of the upward movement of the second portion, a corresponding transfer of force results with a rotation of the helix drive;
- wherein the helix drive comprises a stem with outer surface defined with a plurality of channels that upwardly curve around and along an extent of the stem;
- and
- wherein the second portion comprises a plurality of bearings each rigidly secured to the second portion, the bearings correspondingly received within the channels of the helix drive stem;
- whereby the bearings are directed to move upwardly along the channels of the helix drive stem in event of the upward movement of the second portion relative to the first portion, and corresponds with the rotation of the helix drive stem relative to the second portion and a corresponding rotation of the gearing configuration.

A driving unit for tooling usable with metal-fabricating presses or other machines comprising:
- an upper portion and a lower portion operably linked to the upper portion so as to be movable relative to the upper portion, whereby in event of a downward force contacting the upper portion and contact being made between the lower portion and a rigid structure, upward movement of the lower portion results relative to the upper portion;
- planetary gearing operably linked to the lower portion;
- an assembly for tooling operably linked to the planetary gearing;
- and
- a helix drive that operably links an input or ring gear of the planetary gearing to one of the upper portion or the lower portion;
- whereby the upward movement of the lower portion triggers rotation of the input or ring gear of the planetary gearing via linkage with the helix drive;
- wherein a rotation of the input or ring gear of the planetary gearing corresponds with a greater rotation of an output or sun gear of the planetary gearing, and wherein the output gear is operably linked to the assembly for tooling, whereby a rotation of the output gear corresponds with a same rotation of the assembly for tooling;
- and
- wherein the planetary gearing comprises one or more sets of intermediary or planet gears operably linking the input gear with the output gear, whereby the rotation of the input gear corresponds with a greater rotation of the one or more sets of intermediary gears, and the rotation of the one or more sets of intermediary gears corresponds with a greater rotation of the output gear.

A tool assembly usable with metal-fabricating presses or other machines comprising:
- an upper portion and a lower portion, the upper and lower portions operably coupled;
- a head portion operably coupled to the upper portion and configured for contact and downward movement from a machine ram stroke;
- and
- a driving unit comprising a singular helix drive and a transmission assembly operably coupled to the drive, the head portion operably coupled to the helix drive;
- and
- an assembly for tooling operably linked to the transmission assembly;
- whereby downward linear movement of the head portion from the machine ram stroke results in rotational movement of the helix drive relative to the head portion, and whereby the rotational movement of the helix drive results in enhanced rotational movement of the transmission assembly, and whereby the enhanced rotational movement of the transmission assembly results in corresponding rotational movement of the assembly for tooling;
- wherein the helix drive is rotatable relative to the lower portion, whereby rotation of the helix drive is triggered by the upward movement of the lower portion;
- and
- wherein the assembly for tooling is situated below and in line with the helix drive.
