A bending machine is a common metal processing equipment, mainly used to bend metal sheets into desired shapes. The following will introduce in detail the type, structure, working principle and usage of the bending machine.

1. Types of bending machines

According to different processing needs and processing objects, bending machines can be divided into several types such as manual bending machines, hydraulic bending machines, CNC bending machines and contour bending machines.

Manual bending machine: simple to operate, suitable for lightweight and small batch production.

Hydraulic bending machine: driven by a hydraulic system, it can bend larger-sized plates, has high work efficiency, and is suitable for small and medium-sized batch production.

CNC bending machine: Programmable automatic control, capable of bending metal sheets of various shapes with high precision, suitable for mass production.

Contour bending machine: It is suitable for bending special-shaped plates and completes complex bending operations through molds.

2. Structure of bending machine

Generally, a bending machine consists of a body, a workbench, a tool holder, an upper mold, a lower mold, a transmission system and a control system.

Body: the main part of the bending machine, which can be divided into small, medium and large according to the length of the body.

Workbench: used to support the metal sheet to be processed and adjust the bending angle.

Tool holder: It is installed on the fuselage and fixes the upper mold. It realizes the movement of the upper and lower molds through the transmission system to complete the bending operation of the plate.

Upper and lower dies: move up and down to complete the bending of the plate, usually made of steel.

Transmission system: It is composed of motor, reducer, gear, etc., which converts the power of the motor into mechanical energy to drive the movement of the upper and lower dies.

Control system: used to control the start, stop and setting of the bending angle of the bending machine, usually in the form of a CNC system or human-machine interface.

3. Working principle of bending machine

The bending machine completes the bending operation of the plate through the movement of the upper and lower dies. Specific steps are as follows:

1. Place the metal sheet to be processed on the workbench, and adjust the height and bending angle of the workbench.

2. Set the required bending angle and position and start the bending machine.

3. Its transmission system starts to drive the upper and lower molds to move.

4. The upper mold moves downward, contacts the plate and applies pressure to bend it into the required shape.

5. The upper mold exits and a bending operation is completed.

4. How to use the bending machine

1. Before use, check whether all its parts are intact and perform necessary maintenance and repairs.

2. Place the metal sheet to be processed on the workbench, and adjust the height and bending angle of the workbench.

3. Set the required bending angle and position, and select the appropriate upper and lower dies.

4. Start the bending machine and complete the bending operation according to the set requirements.

5.After use, the surface and interior of the machine should be cleaned, and the machine should be maintained.
