The bending machine with single-stage cylindrical gearbox is a kind of equipment for bending and forming a sheet by using a work roll, and can form parts of different shapes such as a cylindrical piece and a cone, and is a very important processing equipment. The working principle of the coiling machine is to make the work roll move by the action of external force such as hydraulic pressure and mechanical force, so that the sheet is bent or rolled. According to the rotation movement and position change of the work rolls of different shapes, elliptical parts, curved parts, cylindrical parts and the like can be processed.

Working principle：

The oil acts on the piston for vertical lifting movement, and the final gear of the main hard tooth surface reduction gearbox drives the two lower roller gears to engage in a rotary motion to provide torque for the rolled sheet. The flat plastic sheet of the coiling machine with cylindrical gearing arrangement passes through the three work rolls (two lower rolls and one upper roll) of the coiling machine, and the metal plate passes through multiple passes by the lower pressing of the upper roll and the rotating motion of the lower roll. Continuous bending (inner layer compression deformation, middle layer constant, outer layer tensile deformation), permanent plastic deformation, roll into the required cylinder, cone or part of them. The disadvantage of this hydraulic three-roll bending machine is that the end of the plate needs to be pre-bent by means of other equipment.

Structural features：

The automatic feeding equipment of the coiling machine is mainly composed of a sheet material trolley, an actuator, a sheet conveying mechanism and an auxiliary mechanism. The sheet trolley is used to place the sheet to be rolled. The main function of the actuator is to transport the sheet to be rolled on the sheet trolley to the feeding platform. The handling of the sheet is mainly applied to the Cartesian robot and the vacuum chuck picking device. In industrial automation systems, it is often necessary to pick and load workpieces, and vacuum chucks are widely used as suction-cup robots.

The transmission mode of the Cartesian robot is mainly mechanical transmission (zsy series cylindrical gearbox units ,gear rack drive, timing belt drive, ball screw drive), Capacitor start 120v electric motor drive and pneumatic drive. The sheet conveying mechanism is mainly used for conveying the sheets to be rolled, and the roller shaft transmission and the universal ball transmission are common. The main function of the auxiliary mechanism is to improve the accuracy of sheet metal rolling. Common auxiliary mechanisms include sheet center alignment device, pushing device and displacement detecting device.

Operational notes:

1. The bending machine must have a person responsible for management.
2. The operator must be familiar with the structural performance and usage of the coiling machine and only operate with the consent of the management personnel.
3. Check the safety device carefully before starting the machine.
4. When operating, it is strictly forbidden to place the hands and feet on the rollers and transmission parts(ZQ Involute Cylindrical Gearbox Reducer) and workpieces.
5. After the work is interrupted, the clutch should be hit to neutral.

6, multi-person collaborative work must have a special person command.

7. It is strictly forbidden to work overload.
8. The dumping reset of the lifting roller of the upper roller and the balance of the upper roller shall be performed after the main drive is stopped.
