*Rich experience in bending process and advanced mold design and manufacturing.

*Electric control system: Adopting Japanese Mitsubishi servo driver, servo motor, positioning module, CPU, etc., with strong performance and good stability

*Mitsubishi's ultra large CPU can accommodate 1000 sets of file editing,

*Equipped with automatic error and fault detection function, and displayed on the screen, making it easy for operators to eliminate obstacles

*The machine is equipped with an automatic oil injection system, which can reduce the friction of the bent pipe, improve the service life of the core rod, and ensure the quality of the bent pipe

*The control adopts a Japanese Mitsubishi programmable controller.

*Electrical control can achieve three functions: jog, single action, and automatic.

*Adopting an integrated channel block structure, the hydraulic system has high reliability.

*Equipped with a core rod mechanism, it can be bent with or without a core.

*Equipped with safety limits and emergency stop buttons to ensure operator safety.

*Changing the mold can bend various profiles.

*The clamping and core rod parts are equipped with separate oil cylinder transmission. When the bending arm rotates, the pipe can achieve high-precision bending and forming under the joint constraints of the above parts and the mold parts.

 

 

The structural composition of the machine includes the bed part, main transmission part, clamping part, guide part, core rod mechanism, hydraulic system, electrical system, mold part, feeding part, and corner part

 

1. Bed part

The bed body is a bent welded structure that serves as a carrier for other parts.

 

2. Main transmission part

The main transmission part is composed of three parts: the spindle, sprocket, and servo, which can achieve bending and return movements.

 

3. Clamping part

The clamping structure is used to clamp the pipe, which rotates with the spindle to make the mold and pipe fittings rotate simultaneously.

 

4. Guiding part

The guide mechanism holds the straight part of the pipe during the bending process, and during the bending process, the pipe moves forward with the guide mold. The clamping action of the clamping guide structure is driven by a hydraulic cylinder, and by opening the side peephole cover plate, it can be inspected, repaired, and adjusted.

 

5. Core rod part

The core rod mechanism is located at the rear of the bed, and the required bending radius of the core rod can be adjusted through screw transmission. The action of the core rod is achieved by the core rod and oil cylinder, and the leading amount of the core rod can be adjusted by adjusting the nut. The bed is equipped with a core rod support device, support core rod, and pipe fittings. If there is no core bending, the core rod can be removed.

 

6. Hydraulic system

The control components of the hydraulic system are imported from Taiwan, and the hydraulic system adopts an integrated channel block structure. The hydraulic pipelines are made of seamless steel pipes, high-pressure hoses are used at the movable connections, and "U" shaped quick fitting joints are used to prevent system leakage and improve the reliability of the hydraulic system.

 

7. Electrical system

The electrical system is powered by a 50HZ, 380V three-phase AC power supply, and the control line is routed through a 380/110V control transformer to control the operation of contactors, intermediate relays, and solenoid valves. The main electrical components are imported brands, and the power line is mainly driven by a Y-series three-phase asynchronous motor to drive the hydraulic system. The main control components are microcomputer program controllers, and all control button signals come from the safety strong current cabinet.

 

8. Mold section

The mold of the machine consists of a bending mold, a movable jaw, a pressure mold, a core head, etc. It can also be added with wrinkle resistant plates and soft core heads according to the needs of users and actual bending pipes to improve the quality of pipe bending.

 

9. Safety protection

This machine is equipped with safety limits and emergency stop buttons to ensure the safety of the operator.

 

 

1. The equipment is guaranteed for 12 months after leaving the factory. The time shall be calculated from the date of final acceptance after delivery. During the warranty period, if there are manufacturing quality issues, the supplier shall provide free warranty. If any other reasons arise, the user shall bear the reasonable repair cost. After the warranty period expires, we will still provide good service and charge reasonable fees.

 

2. When the equipment malfunctions during use, the supplier shall respond immediately upon receiving notification from the purchaser. If it cannot be directly resolved over the phone, the general fault should be resolved within 6 hours, and major faults should be resolved as quickly as possible. In principle, it should not exceed 24 hours (excluding holidays).

 

3. The supplier is responsible for free installation and debugging of the equipment, as well as technical training. The training is divided into two phases. The first phase involves sending one relevant personnel from the buyer to the supplier's factory before delivery, and conducting training during pre acceptance; After the equipment is handed over to the purchaser for the second time, the supplier will send technical personnel to the purchaser's site for secondary training during installation, debugging, and final acceptance.

 

4. The supplier is responsible for timely feedback on the development trend of new processes to the buyer, introducing the characteristics of new equipment, providing advanced technology and processes, and explaining the buyer's doubts.

 

5. Please further negotiate with the sales department regarding any outstanding matters.
