Abstract
A trimming apparatus and method that can create plural trim shapes using one press die. The trimming apparatus includes a conveying device for conveying a pallet having a workpiece disposed thereon, a trimming device having a press die for trimming the workpiece in a trimming process area, a positioning device for determining the relative position of the press die with respect to the pallet and a position switching device provided in the positioning device to change operable to change the position of the press die with respect to the pallet in the trimming process area.
Claims19
A trimming apparatus, comprising:
- a conveying device for conveying a pallet having a workpiece disposed thereon;
- a press die operable to form a first trim shape on the workpiece when the pallet is positioned in a first predetermined position with respect to the press die, and operable to form a second trim shape on the workpiece when the pallet is positioned in a second predetermined position with respect to the press die;
- a positioning device operable to set the position of the pallet with respect to the press die to the first predetermined position;
- a position switching device operable to change the position of the pallet with respect to the press die to the second predetermined position;
- and
- a control device configured to enable the production of both the first and second trim shapes by being configured to selectively either control the position switching device to position the pallet at the first predetermined position with respect to the press die and thereafter operate the press die to form the first trim shape on the workpiece while the pallet is positioned at the first predetermined position, or control the position switching device to position the pallet at the second predetermined position with respect to the press die, and thereafter operate the press die to form the second trim shape on the workpiece while the pallet is positioned at the second predetermined position.

A trimming apparatus, comprising:
- means for conveying a pallet having a workpiece disposed thereon;
- means for trimming the workpiece according to a first trim shape when the pallet is positioned in a first predetermined position with respect to the means for trimming, and according to a second trim shape when the pallet is positioned in a second predetermined position with respect to the means for trimming;
- means for setting the position of the pallet with respect to the means for trimming to the first predetermined position;
- means for changing the position of the pallet with respect to the means for trimming to the second predetermined position;
- and
- means for enabling the production of both the first and second trim shapes by being configured for selectively either controlling the position switching device to position the pallet at the first predetermined position with respect to the press die, and thereafter operate the press die to form the first trim shape on the workpiece while the pallet is positioned at the first predetermined position, or controlling the position switching device to position the pallet at the second predetermined position with respect to the press die, and thereafter operate the press die to form the second trim shape on the workpiece while the pallet is positioned at the second predetermined position.
3 more elements
A trimming apparatus, comprising:
- a shuttle type conveying device, for conveying a pallet having a workpiece disposed thereon, the shuttle type conveying device including a reciprocating shuttle member having a plurality of finger parts mounted thereon for movement between an engaged position wherein a finger part of the plurality of finger parts engages the pallet so that movement of the shuttle member moves the pallet and a disengaged position wherein the finger part of the plurality of finger parts does not engage the pallet so that the shuttle member may move with respect to the pallet;
- a press die operable to form a first trim shape on the workpiece when the pallet is positioned in a first predetermined position with respect to the press die, and operable to form a second trim shape on the workpiece when the pallet is positioned in a second predetermined position with respect to the press die;
- a positioning device operable to set the position of the pallet with respect to the press die to the first predetermined position;
- and
- a position switching device mounted on the shuttle member for moving the finger parts to a predetermined position with respect to the press die and operable to change the position of the pallet with respect to the press die to the second predetermined position.
