Abstract
A plate workpiece processing machine includes a workpiece support, a tool punch holder, a tool die holder, a tool drive, multiple tool punches, and multiple tool dies. Various tool punches and tool dies have tool heads of differing heights. The tool punch holder is positionable based on the tool head height of a tool punch secured to the tool punch holder and/or the tool die holder is positionable based on the tool head height of a tool die secured to the tool die holder.
Claims21
A plate workpiece processing machine, comprising:
- a workpiece support;
- a tool punch holder configured to hold a tool punch;
- a tool die holder configured to hold a tool die;
- a tool drive operable to move at least one of the tool punch holder and the tool die holder to reduce a separation between the tool punch holder and the tool die holder along a stroke axis for processing of a plate-like workpiece supported on the workpiece support;
- a plurality of tool punches selectively mountable on the tool punch holder, each of the tool punches having a tool punch shank and a tool punch head adjoining the tool punch shank, the tool punch shank of each tool punch being configured to be secured to the tool punch holder and the tool punch head of each tool punch being radially enlarged relative to the tool punch shank and being arranged towards the workpiece when the tool punch is mounted on the tool punch holder;
- and
- a plurality of tool dies selectively mountable on the tool die holder, each of the tool dies having a tool die shank and a tool die head adjoining the tool die shank, the tool die shank of each tool die being configured to be secured to the tool die holder and the tool die head of each tool die being radially enlarged relative to the tool die shank and being arranged towards the workpiece when the tool die is mounted on the tool die holder,
- wherein the tool punch heads of at least some of the tool punches have differing heights along the stroke axis as mounted on the tool punch holder, and the tool die heads of at least some of the tool dies have differing heights along the stroke axis as mounted on the tool die holder, and
- wherein the tool drive is configured to position the tool punch holder with respect to the stroke axis based on the tool punch head height of a tool punch secured to the tool punch holder, and to position the tool die holder with respect to the stroke axis based on the tool die head height of a tool die secured to the tool die holder.
6 more elements
A plate workpiece processing machine, comprising:
- a workpiece support;
- a first tool holder;
- a second tool holder;
- a tool drive operable to move at least one of the first and second tool holders to reduce a separation between the tool holders along a stroke axis for processing of a plate-like workpiece supported on the workpiece support;
- a plurality of first tools selectively mountable on the first tool holder, each of the first tools having a first tool shank and a first tool head adjoining the first tool shank, the first tool shank of each first tool being configured to be secured to the first tool holder and the first tool head of each first tool being radially enlarged relative to the first tool shank and being arranged towards the workpiece when the first tool is mounted on the first tool holder;
- and
- a plurality of second tools selectively mountable on the second tool holder, each of the second tools having a second tool shank and a second tool head adjoining the second tool shank, the second tool shank of each second tool being configured to be secured to the second tool holder and the second tool head of each second tool being radially enlarged relative to the second tool shank and being arranged towards the workpiece when the second tool is mounted on the second tool holder,
- wherein the first tool heads of at least some of the first tools have differing heights along the stroke axis as mounted on the first tool holder, and the tool drive is configured to position the first tool holder with respect to the stroke axis based on the first tool head height of a first tool secured to the first tool holder.
5 more elements
A method of processing a workpiece, the method comprising:
- holding a first tool in a first tool holder, and holding a second tool in a second tool holder, the first tool having a first tool head adjoining a first tool shank, the first tool head being arranged on a workpiece side of the first tool shank, the second tool having a second tool head adjoining a second tool shank, the second tool head being arranged on a workpiece side of the second tool shank, and the first and second tool holders being spaced along a stroke axis;
- and
- positioning the first tool holder along the stroke axis based on the height of the first tool head.
