Bidirectional feeding multi-knife bending automatic alignment process method for numerical control bending machine

Abstract

The invention discloses a bidirectional feeding multi-knife bending automatic alignment process method for a numerical control bending machine. According to the bidirectional feeding multi-knife bending automatic alignment process method for the numerical control bending machine, a multi-axis composite feeding device, a bending machine workbench and a numerical control system are provided. The process method comprises the following steps: S1, mounting one area-array camera at each of the left end and the right end of the bending machine workbench; S2, controlling by a numerical control systemto trigger the area-array camera to take photos, acquiring an image of a to-be-detected workpiece in real time, uploading and feeding back the image information to the numerical system, processing byimage detection software, displaying curve fitting result on a display and replacing artificial sample plate measuring; and S3, when a back half arc is bended, detecting the error of a bending line and machine tool line laser cluster on the workpiece in real time, controlling operation of the multi-axis composite feeding device and completing automatic positioning of the back half arc bending. Theartificial sample plate detection process is omitted, automatic positioning of the whole feeding process is realized, automatic acquisition of bending forming shape is completed and the industrial automation degree is high.

Description

【Technical field】 [0001] The invention relates to the technical field of numerically controlled bending machines, in particular to an automatic alignment process method for bidirectional feeding and multi-knife bending for numerically controlled bending machines. 【Background technique】 [0002] CNC bending machine is a plate forming machine that uses the equipped mold (general or special mold) to bend the metal plate in the cold state into various geometric cross-sectional shapes. It is widely used in automobiles, aircraft manufacturing, light industry, shipbuilding, Plate bending processing for containers, elevators, railway vehicles and other industries. In engineering cranes, the lower flange of the crane jib also needs to be bent and formed by a CNC bending machine, which puts forward higher requirements for bending quality and bending efficiency. However, in the actual operation process, the X1 positioning feeding mechanism and the X2 positioning feeding mechanism on t...
