Abstract
A lower metallic die has a major surface for supporting a workpiece thereon. A ridgeline is formed on an end portion of the major surface and with which a bending portion of the workpiece is brought into contact. An upper metallic die has a plane surface rotatable in a bending direction of the workpiece to clamp the workpiece together with the ridgeline of the lower metallic die, thereby freely bending the workpiece at one angle of desired various angles. A rotation controller controls rotation of the plane surface of the upper metallic die, thereby rotating and positioning the plane surface at a position of the one angle of the desired various angles.
Claims13
A metallic die device for a press machine, comprising:
- a lower metallic die having a major surface for supporting a workpiece thereon, and a ridgeline which is formed on an end portion of said major surface and with which a bending portion of the workpiece is brought into contact;
- an upper metallic die, having a plane surface which is rotatable in a bending direction of the workpiece, for clamping the workpiece together with said ridgeline of said lower metallic die, thereby freely bending the bending portion of the workpiece at one angle of desired various angles;
- and
- rotation control means for controlling rotation of said plane surface of said upper metallic die, thereby rotating and positioning said plane surface at a position of said one angle of the desired various angles;
- said rotation control means including a metal backup member for relatively pushing said plane surface of said upper metallic die, thereby rotating said plane surface of said upper metallic die in the bending direction;
- and
- each of said upper metallic die and said metal backup member including means for fine-moving and positioning itself in a direction parallel to said major surface of said lower metallic die at a distance which is a function of at least one of the thickness and material of the workpiece.

A metallic die device for a press machine, comprising:
- a lower metallic die having a major surface for supporting a workpiece thereon, and first and second ridgelines which are formed on first and second end portions thereof divided along said major surface thereof and with which first and second bending portions of the workpiece are brought into contact;
- an upper metallic die having first and second plane surfaces, said plane surfaces being rotatable in respective bending directions of the first and second bending portions of the workpiece, for clamping the first and second bending portions of the workpiece together with said first and second ridgelines of said lower metallic die, thereby freely bending the first and second bending portions of the workpiece at one angle of desired various angles, respectively;
- means for fine-moving and positioning said upper metallic die against said lower metallic die at a distance which is a function of at least one of the thickness and material of the workpiece;
- and
- rotation control means for controlling rotation of said first and second plane surfaces of said upper metallic die, thereby rotating and positioning said first and second plane surfaces at a position of the one angle of the desired various angles, respectively;
- said rotation control means comprising at least one motor for rotating and positioning said first and second plane surfaces of said upper metallic die.
