Abstract

The invention discloses a local bending mechanism which comprises a local bending sliding rail, a left local bending assembly and a right local bending assembly. The left local bending assembly and the right local bending assembly are installed on the local bending sliding rail in a sliding mode and symmetrically arranged at the two ends of a bending machine lower tool; the left local bending assembly and the right local bending assembly are each provided with a local bending tool set and a tool selection air cylinder; the left local bending assembly comprises a left mounting frame and a left cutter driving mechanism; the right local bending assembly comprises a right mounting frame and a right cutter driving mechanism; and each local bending cutter set is formed by connecting a plurality of local bending cutters into a whole through a clamping pin mechanism, and the cutter selection air cylinders are installed on the left mounting frame and the right mounting frame. According to an automatic bending machine additionally provided with the local bending mechanism, the bending problem of a product needing bending at the two ends and needing no bending in the middle can be well solved, and the automatic bending machine can adapt to more products.

Description

technical field [0001] The invention relates to the technical field of bending machines, and more specifically relates to a mechanism capable of partial bending. Background technique [0002] The CNC bending machine uses the equipped mold (general or special mold or tool) to bend the metal sheet in the cold state into workpieces of various geometric cross-sectional shapes. It is a sheet metal forming machine designed for cold-rolled sheet metal processing, and is widely used in sheet metal bending processing in industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, and railway vehicles. [0003] The length of the bending tool of the existing automatic bending machine is not variable, and it is mostly the same as the maximum hemming length. When the product needs to be bent at both ends but does not need to be bent in the middle, the product cannot be bent on the automatic bending machine, which makes the operation of the...
