sheet metal bending machine

Abstract

A metal sheet bending machine, comprising: a main bending tool member (2; 6) extending along a longitudinal direction (A) and movable for bending a workpiece (50); and the main bending tool member (2; 6) ) an associated and parallel guide member (3) extending through the working area (W) of the bending machine (1) and protruding laterally from the bending machine at least with a first end portion (4); and Shuttle members (21, 22, 23) slidably mounted on said guide member (3) and supporting at least one auxiliary tool (41, 42) for association with said main bending tool member (2; 6) , thereby performing a partial bending of the workpiece (50); the shuttle member (21, 22, 23) can be in a first active position (P1) and a first inactive position (R1) along the longitudinal direction (A) ), wherein in the first active position, the shuttle members (21, 22, 23) are located inside the working area (W), and the auxiliary tools (41, 42) are mounted on the main bending tool member (2; 6), while in said first inactive position said shuttle member (21, 22, 23) is located outside said working area (W) and positioned on said guide member (3) at the first end portion (4) of 41, 42), the shuttles (21, 22, 23) are connected to each other to form a first shuttle group (13) with an optional number of shuttles (21, 22, 23); the first shuttle group ( 13) Moveable between the first inactive position (R1) and the first active position (P1) in order to mount the defined assembly of auxiliary tools (41, 42) on the main bending tool On component (2;6).

Description

technical field [0001] The invention relates to a bending machine for bending or folding metal strips, segments, plates and sheets for the manufacture of semi-finished and / or finished products. In particular, the invention relates to a bending machine provided with a system for automatically mounting or dismounting auxiliary or additional bending tools adapted to perform partial bending on workpieces. Background technique [0002] Known bending machines or press brakes include mechanical, hydraulic, pneumatic or electrically servo-operated presses that move an upper tool or punch vertically relative to a lower tool or die to deform a workpiece inserted between the tools machine. The upper punch applies a force to the workpiece that deforms and bends the workpiece according to the angle defined by the shape of the tool. The lower die is fixed to the machine frame and includes a longitudinal opening or channel that cooperates with the upper punch to bend the workpiece. [0...
