Hydraulic CNC bending machine is a tool that uses the equipped molds (universal or specialized molds) to bend metal sheets in a cold state into various geometric cross-sectional shapes of workpieces. It is a sheet metal forming machine designed for cold-rolled sheet metal processing, widely used in sheet metal bending processing in industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, railway vehicles, etc.

Performance and characteristics of hydraulic CNC bending machine:

1. Streamlined design, high configuration, high-precision fully CNC bending machine equipment; Electro hydraulic servo system, fully closed-loop control slider synchronization;

2. The standard is 3+1 axis - Y1 (left cylinder up and down), Y2 (right cylinder up and down), X (rear gear front and rear), V (hydraulic deflection compensation);

3. Additional options such as 4+1 axis, 6+1 axis, or more can be added according to user requirements;

4. Standard CNC systems include DELEM from the Netherlands and ZR from Taiwan;

5. Adopt a dual deflection compensation mechanism with upper and lower components Mechanical upper module speed clamping device, which has both fast clamping function and upper module compensation function—— Hydraulic upper module speed clamping device, automatically controlled and compensated by a numerical control system;

6. The key hydraulic and electrical components are all branded products;

7. Standard linear guide type movable rear material stop finger;

8. Randomly equip one set of standard upper and lower molds;

Working principle of hydraulic CNC bending machine:

The hydraulic bending machine includes a bracket, a worktable, and a clamping plate. The worktable is placed on the bracket, and the worktable consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base consists of a seat shell, a coil, and a cover plate. The coil is placed in a recess of the seat shell, and the top of the recess is covered with a cover plate.

When in use, the coil is energized by a wire, which generates an attractive force on the pressure plate, thereby achieving the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into various workpiece requirements and can also process workpieces with side walls. The bending machine can meet the needs of various workpieces by replacing the bending machine mold.
