Plate material processing machine with bending function and tool for the same

Abstract

The present invention provides a plate material processing machine with a bending function which enables even a bending piece with two or more bending portions to be bent and which enables materials to be bend so as to have different bending directions, dimensions, angles, or the like using the same tools. An upper tool 21 and a lower tool 22 are provided which fix a plate material W by sandwiching it between themselves. An upper tool-side bending tool 23 and a lower tool-side bending tool 24 are provided on sides of the upper tool 21 and lower tool 22, respectively, so as to elevate and lower freely. The upper tool-side bending tool 23 and the lower tool-side bending tool 24 perform elevating and lowering operations relative to the upper tool 21 and the lower tool22 to bend a plate material piece Wa of a plate material W sandwiched between the upper tool 21 and the lower tool 22. A plate material feeding mechanism adjusts the length over which the plate material piece Wa projects from the upper tool 21 and lower tool 22.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a plate material processing machine with a bending function such as a punch press, a laser processing machine, or a punch and laser composite machine which has a processing function of bending a plate material piece upward and downward, as well as a tool used for this plate material processing machine. BACKGROUND OF THE INVENTION [0002] Some conventional punch presses such as turret punch presses are provided with a forming tool instead of a punching tool to enable various forming operations such as burring and louvering. [0003] The above-mentioned conventional punch press is disclosed, for example, in the Examined Japanese Patent Application Publication (Tokkou-Hei Number 7-85816) [0004] However, the forming tool in the conventional punch press can provide only a specified shape and size. It cannot provide different bending sizes or angles even when processed materials have similar shapes. For example, if bending pieces...

AI Technical Summary

Benefits of technology

The present invention is a plate material processing machine with a bending function that can produce bending pieces with multiple bending portions. The machine includes an upper and lower tool that can fix a plate material between them and a plate material feeding mechanism that can feed the plate material in a predetermined direction. The machine also has an upper and lower tool-side bending tool that can elevate and lower to perform bending operations on the plate material piece. The bending angle can be adjusted by changing the position of the bending tools. The machine can produce bending pieces with different bending directions and can also have a detouring space to prevent interference with the tools. The machine can efficiently produce bending pieces with multiple bending portions and can adjust the bending angle easily.

Problems solved by technology

Since a bending piece with two or more bending portions can be produced by feeding the plate material in the same direction, it is unnecessary to perform complicated operations such as rotation of the plate material around the tool.
