                                            The maximum bending capacity of dw-75nc semi-automatic pipe bender reaches Φ 76*2.5mm iron pipe. The main structural parts of the machine are integrally formed by casting parts, and the structure is firm and reliable. The equipment pushes the rack elbow through the oil cylinder, with great bending torque, suitable for bending medium and large diameter and thick wall pipe fittings. It can also bend square tube, rectangular tube, angle steel, special-shaped tube and other profiles with different molds.

                                            Working Principle

                                            Dw-75nc semi-automatic pipe bender adopts pure hydraulic power to drive the equipment.
                                            The equipment drives the rack through the hydraulic cylinder, drives the gear to rotate, and drives the elbow arm to work, so as to realize the bending of pipe fittings. The bending angle is fed back by rotary encoder to realize the digital control of bending action. With the hydraulic slow bending function, the bending angle can be controlled more accurately, especially suitable for the bending processing of products with single or multiple bending angles in the same horizontal plane.
                                            The disassembly actions of the machine include clamping, bending, core pulling and side auxiliary pushing.
                                            Action flow of semi-automatic bending:
                                            1. Clamping pipe fittings (hydraulic drive, triangular locking structure design clamping pipe fittings);
                                            2. Elbow (driven by oil cylinder, the oil cylinder pushes the rack to drive the gear to rotate for elbow, and the encoder controls the angle);
                                            3. Core pulling (hydraulic drive, used when bending thin-wall and small radius pipe fittings, can be closed);
                                            4. Side auxiliary pushing (controlled by oil cylinder, carried out at the same time with the bending action, and assisted the forming of pipe fittings).

                                            Single chip computer control, easy to use
                                            Dw-75nc semi-automatic pipe bender is controlled by single chip microcomputer and operated by touch on Chinese screen, which is simple and easy to use. Preset manual and automatic modes, and only need to input simple parameters such as bend angle and other action time to realize automatic bending cycle
                                            With safety functions such as personnel anti pinch and equipment thermal overload
                                            This machine is designed with multiple safety protection devices, such as the anti pinch emergency stop on the inner side of the elbow arm and the emergency stop switch on the operation screen, which can stop the power motor of the equipment immediately in case of emergency to prevent personal injury. At the same time, the machine has thermal overload shutdown protection function to prevent equipment damage under abnormal working conditions
                                            Clamping structure of triangle locking design
                                            The clamping structure adopts the triangular locking structure design, and the orifice plate mechanism is pushed by the hydraulic cylinder to achieve the three-point one-line locking function, which can effectively improve the reliability of the elbow.
                                            Quick change mold design, convenient for flexible production
                                            Semi-automatic pipe benders are often used in small batch and multi variety production conditions, requiring frequent replacement and adjustment of molds. This machine adopts a rapid die interface design, different dies can realize rapid disassembly and assembly, and micro adjustment can immediately bend the pipe.
                                            Air cooling or water cooling
                                            According to the environmental requirements of the customer's factory, the machine provides water cooling or air cooling system for selection. The water cooling effect is better, but the customer needs external circulating cooling water. Air cooling has certain heat dissipation effect, without any other external peripherals.
                                            Strengthen the structural rigidity of the equipment, and the elbow is easier and more stable
                                            The main structural parts of this machine are integrally formed by casting parts, and the structure is firm and reliable. At the same time, each component has been strengthened to make it more rigid, and the bending of pipe fittings is easier and more stable.

                                            Video Presentation

                                            In this video, 50x2mm iron pipes are bent, and the pipe fittings are relatively thin-walled and thin. At the same time, customers have high requirements for the deformation of the bending part and the smooth transition at the end of the bending arc. Therefore, although the bending radius is large, the method of through core bending is still adopted. The anti wrinkle die and the core piercing die are effectively matched, which can make the bending part meet the customer's requirements.
