Hydraulic numerical control bending machine

Abstract

The invention relates to a hydraulic numerical control bending machine comprising a bending machine body, active material supporting frames and an auxiliary material supporting frame, the active material supporting frames are symmetrically arranged on the left side and the right side of the front end of the bending machine body, and the auxiliary material supporting frame is installed in the middle of the front end of the bending machine body. The hydraulic numerical control bending machine can solve problems that a traditional material supporting frame is fixed in structure and difficult to deform and adjust, the material supporting frame can support a plate before bending, however, the material supporting frame cannot support the plate synchronously along with bending of the plate in the bending process, at the moment, parts on the two sides of the bending position are usually in a suspended state, and due to the fact that the front half part of the plate is usually long and heavy, the plate of the part may be excessively bent due to the fact that the suspended part is too large or too heavy, then the bending precision is influenced; after each time of bending, a worker needs to take out a detection tool to detect the bending degree of the plate, the situation that the bending degree does not reach the standard is prevented, and the situation that the efficiency of an assembly line is influenced by manual detection is prevented.

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...

Problems solved by technology

[0003] 1. The structure of the traditional support frame is fixed, and it is difficult to adjust the deformation. 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;
