This machine model: HDLW12-four-roller plate bending machine

Our factory features:
1. Innovative design
2. Competitive price
3. High-quality machine
4. Attentive service
5. A strong technique team
6. Professional stuffs
7. Close to Shanghai port, easy transportation

The movement of each roller of four-roller plate bending machine
1. The top roller makes rotation movement drove by hydraulic motor
2. The down roller makes rotation drove by hydraulic motor as well as making up-down movement drove by hydraulic cylinder.
3. The side rollers make arc swing movement drove by hydraulic oil cylinder.

The advantages of four-roller bending machine
1. Hydraulic-driven, high efficiency and energy saving (the driving power is only 60% of traditional bending machine)
2. Permanent lubricant technology (no refueling within bearing life period)
3. Clamping pressure is adjustable (no slipping, and the production efficiency is 50%-80% higher than three roller plate rolling chine
4. The cylinder diameter can achieve 1.1 times of top roller diameter

The features of our four-roller plate rolling machine
1. CNC control system
2. Leveling easily
3. One-time circle formed
4. More convenient to roll large cone
5. Easy to correct the wrong edge
6. The side roller makes arc swing, so the leverage increase the force to form cylinder
7. It adopts proportional valves synchronization for the two sides of side rollers.
The four-roller plate bending machine is proper for the following user:
1. The four-roller plate bending machine will be good choice for the customer who is the first time to use plate bending machine, since the four-roller bending machine is very easy to be operated.
2. The four-roller plate bending machine will be good choice for the operator who is lack of operation experience, but he wants to increase the production efficiency
3. The four-roller plate bending machine will be good choice for the customer who want to have high precision and improve the products quality
4. The four-roller plate bending machine will be good choice for the boss who wants to use only one operator to save labor cost
5. If the steel plate is in the large size or the customer request high throughput or for the sake of safety, the customer needs handling device, feeding table and top & side support device, the four-roller machine will be good choice.
6. The four-roller plate bending machine will be good choice for the boss who wants to use CNC control and so on.
