Precision DA69T Electric Hydraulic Press Brake

8+1 axis bending machines, such as the WE67K series, equipped with the DA69T system, are able to handle a wide range of metal bending applications, from simple to complex shapes. This type of bending machine is particularly suitable for the manufacture of deep boxes and other complex shapes, providing high precision, high efficiency and versatility.

Application examples of the DA69T system in 8+1 axis bending machines.

• WE67K-100T/3200: This bending machine is equipped with the DA69T system, which can be easily programmed and operated, and is suitable for bending a variety of metal sheets.

• WE67K-160T3200: Also equipped with the DA69T system, this bending machine has a maximum bending force of 160 tons and a maximum bending length of 3200 mm, which is very suitable for processing large metal sheets.

The quick clamp of electric bending machine is an important accessory for bending machine.

Its main function is to quickly and accurately fix the plate during the bending process to improve processing efficiency and processing accuracy.

The design of the quick clamp enables the operator to quickly complete the positioning and clamping of the workpiece, thereby reducing production preparation time and improving overall production efficiency.

The grating ruler of the electro-hydraulic bending machine is made by using the principle of interference and diffraction of light, and can be used to detect linear displacement or angular displacement.

During the operation of the electro-hydraulic bending machine, it can accurately detect the displacement of components such as the slider, providing basic data for the precise control of the bending machine.

Thereby ensuring the synchronous control accuracy, bending accuracy and repeated positioning accuracy of the bending machine.

The hydraulic system of the electro-hydraulic bending machine is mainly composed of the following parts:

Power element

• Hydraulic pump: responsible for converting mechanical energy into liquid pressure energy.

• Hydraulic cylinder: actuator, converting the pressure energy of the liquid into mechanical force to drive the movement of the bending head2.

Control element

• Hydraulic valve: used to control the flow direction and pressure of the hydraulic oil, thereby realizing various actions and controls of the bending machine2.

Auxiliary element

• Hydraulic oil: as a working medium, transmitting pressure and lubrication.

The compensation amount is automatically calculated and set by the NC system to ensure the consistency of the full-length bending angle.

Advantages

• Parametric intelligent adjustment

• Multi-station compatibility

• Reduce wear on key components

• Impact-resistant structure optimization

• Adapt to complex processing needs

Main functions of laser protection devices

• Protect the safety of operators: detect people or objects in the danger zone and issue an alarm in time.

• Improve production efficiency: help operators complete work faster and reduce downtime and delays caused by safety issues.

• Improve equipment reliability: detect abnormal conditions of equipment and issue an alarm in time to help operators deal with problems in time and avoid equipment damage and accidents.

• Comply with safety standards: comply with relevant safety standards and regulations, help enterprises improve safety management level and reduce the incidence of safety accidents.

The light curtain protection system of the electro-hydraulic bending machine is mainly composed of a light emitter, a receiver, a mounting bracket and a controller.

This system can effectively prevent the fingers and arms of the workers from being crushed when the bending machine is working, and effectively protect the workers.

The light curtain protection system is not only suitable for various forms of workpieces such as flat plate bending, folding box, Z-type bending, etc., but also can concentrate all functions on the operation panel, making it easy for users to switch between various modes.

The workbench and the bracket are in contact through two supporting points, the slider and the bearing, which can better bear the force. The support device drives the workpiece to rotate around the bending center line, and the movement direction of the supporting point is vertical.

Function

Assisted bending process

1. The flap of the front support device can always be close to the bent sheet material, allowing the sheet material to complete a complete bending process and ensure the smooth progress of the bending operation.

Improved stability

2. Some existing support devices have the problem of few force points and poor stability. The improved structure, such as the contact between the slider and the bearing at two fulcrums, can better bear the force, improve the stability of the support device, and thus ensure its performance.

Support sheet material

3. For long and thin sheets, the front support frame (device) can support the sheet material to prevent the sheet material from affecting the bending effect due to its own gravity and other factors.

Convenient operation and production

The material of bending machine mold is generally T8, T10, T10A, and the better one is 42CrMo.

In addition, Cr12MoV is also a good material. It requires high strength, high toughness and good wear resistance, and cold working die steel is often used.

42CrMo is a high-strength alloy quenched and tempered steel with high strength and good toughness. It can work below 500 degrees.
