A hydraulic CNC bending machine

Abstract

The invention relates to a hydraulic numerical control bending machine, which includes a bending machine body, an active support frame and an auxiliary support frame. The left and right sides of the front end of the bending machine body are symmetrically equipped with active support frames. An auxiliary support rack is installed in the middle. The invention can solve the problem that the structure of the traditional bracket is fixed, and it is difficult to adjust the deformation. The bracket can support the sheet before bending, but it will not support synchronously with the bending of the sheet during the bending process. At this time, the parts on both sides of the bend are usually in a suspended state. Since the first half of the sheet is usually longer and heavier, the sheet in this part may be bent too much due to the excessive size or weight of the suspended part, which will affect the In order to ensure the bending accuracy, after each bending, the staff needs to take out the detection tools to detect the bending degree of the sheet metal, so as to prevent the bending degree from not meeting the standard, and manual detection affects the efficiency of the assembly line.

Description

technical field [0001] The invention relates to the technical field of numerical control bending machines, in particular to a hydraulic numerical control bending machine. Background technique [0002] With the development of social economy, the things produced by the factory are becoming more and more sophisticated. While producing high-end products, the requirements for the required equipment are also getting higher and higher. Among them, the bending machine is an indispensable production equipment. The products processed by the bending machine are not only beautiful in appearance, but also have greater structural strength. Due to the advantages of simple operation, low cost and fast response, they are widely used in workpiece bending operations. Hydraulic CNC bending machines When working, the support frame is an important part of the CNC bending machine. When bending the sheet metal, it needs to be supported by the support frame. However, the existing support frame is of...

The support frame can support the sheet before bending, but it will not support synchronously with the bending of the sheet during the bending process. At this time The parts on both sides of the bend are usually in a suspended state. Since the first half of the sheet is usually longer and heavier, the sheet in this part may be too large or heavy, resulting in excessive bending, which affects the bending. Bending accuracy;
