At all times. Types of bending machines

（1） Manual bending machine

Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. Manual bending machines have gained popularity both domestically and internationally due to their advantages such as small size, low energy consumption, high work efficiency, fast production, wide range of applications, and convenient transportation. For example, the reference price for manual folding machines is negotiable. The manual folding machine produced by the brand manufacturer Jiangsu Liuzhong Heavy duty Machine Tool Co., Ltd. has the characteristics of lightweight, energy-saving, high work efficiency, multiple production, wide application range, and easy handling. It can be used to make distribution boxes, electronic switch boxes, fuse turns, and distribution cabinets, and is also widely used in the processing of conveying machinery, handling boxes, various types of boxes, and panels.

（2） Hydraulic bending machine

Hydraulic bending machines are divided into upward and downward movement types according to their motion modes. Upward movement refers to the situation where the worktable and the workpiece on the worktable remain stationary while the slider moves downward. Currently, most of the products on the domestic market are upward movement; The downward movement type refers to the upward movement of the worktable and the workpiece on the worktable together, without moving the slider, which is now relatively rare. According to the synchronization method, it can be divided into mechanical synchronous bending machine, torsion axis synchronous bending machine, machine hydraulic synchronous bending machine, and electro-hydraulic synchronous CNC bending machine. According to the control method, it can be divided into ordinary hydraulic sheet metal bending machines, economical CNC bending machines, and electro-hydraulic synchronous CNC bending machines.

The hydraulic bending machine adopts a fully welded steel structure, which has the characteristics of high strength and hardness. The counter can display accurately, with high precision and stability. The overall structure is complete and easy to use, without the need for high-tech personnel to operate.

（3） CNC bending machine

CNC bending machine is an emerging large-scale machine, and its high precision has been favored by many people. Flexible operation methods can be adopted, which can be linked by two machines to solve the problem of processing long sheets, and can be operated by a single machine to effectively improve utilization and reduce energy consumption. Compensation is automatically adjusted by the CNC system, which is convenient and accurate. For example, common CNC bending machine models include G-type, F-type, WC67K type, etc., which have angle compensation function, real-time detection and feedback correction of grating ruler, full closed-loop control, positioning accuracy of rear stop material and slider dead stop material is ± 0.02mm. The upper mold adopts a fast clamping device, and the lower mold adopts a wedge deformation compensation mechanism. It also has multi-step programming function, which can improve production efficiency.

（4） Pure electric bending machine

Compared to CNC bending machines, pure electric bending machines are more energy-efficient and environmentally friendly, and have higher bending accuracy. The error of each bending of the pure electric bending machine is only 0.01 millimeters. The pure electric bending machine has a fast speed, with a bending speed of up to 20 times per minute. The electric system is very energy-efficient, only consuming power during the pressing process, with an energy efficiency of up to 90%. Pure electric bending machine has good stability, and the electric servo system is like a precision mechanical clock, which can maintain stable bending effect and is not prone to errors. The precision and efficiency of the twisted shaft bending machine products are low, and it is difficult to repair the damaged equipment; CNC bending machine has high precision, improved work efficiency, easy to find the cause of equipment damage, and convenient maintenance; Pure electric bending machines have more advantages in energy conservation, environmental protection, and precision.
