[0002] A press brake is a mechanical device used to bend metal sheets, also known as a bending machine or a bending forming machine. It mainly bends the metal sheet along a pre-set bending line by applying pressure, so that the sheet is formed into the desired geometric shape. It has efficient, precise and flexible processing capabilities, can meet the processing needs of workpieces of different shapes and sizes, and is widely used in the manufacturing industry, especially in the field of metal processing, for the production of various metal products, such as metal boxes, housings, pipes, components, etc. The fixture system in the press brake is used to fix and clamp the metal sheet to ensure the stability and position accuracy of the workpiece during processing. It usually includes a press and a positioning fixture, which can be adjusted and positioned according to the shape and size of the workpiece.

[0003] Based on the above, the inventors have found the following problems: some current bending machine positioning fixtures may be difficult to adjust before workpiece processing, and require a lot of time and manpower to adjust and set up, affecting production efficiency and work efficiency. At the same time, during the workpiece processing, the clamping force of the fixture is unstable and shifted, resulting in inaccurate positioning or position offset of the workpiece, affecting the accuracy and quality of the bending process.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a positioning device for a fully automatic CNC bending machine is provided, in order to achieve a purpose with greater practical value. Utility Model Content

A lower pressing die 4 is installed on the top of the quick-install component, and an upper pressing die 7 is installed on one side of the machine tool 1 at a position above the lower pressing die 4, and a pressing plate 8 is installed at the bottom of the upper pressing die 7.

[0029] Among them, the quick-release assembly includes a lower mold base 2 and a pair of mounting bases 3, and a pair of mounting grooves 13 are provided on both sides of the lower mold base 2, and a through hole 12 is provided on one side of the pair of mounting grooves 13, and a limiting plate 15 is installed on one side of the mounting groove 13. The limiting plate 15 further limits the limiting pin 17 to stabilize the limiting block 16 to prevent the lower pressing mold 4 from shaking during the workpiece processing, and a pair of mounting grooves 20 are provided inside the two ends of the lower mold base 2.
