Fully automatic pipe bending machines represent state-of-the-art equipment in the field, capable of fully automated feeding, rotation, and forming. Thanks to their high precision, stable performance, and safe, user-friendly operation, these machines are widely used for bending pipe components across diverse sectors—including aerospace, automotive, rail transport, motorcycles, shipbuilding, petrochemicals, power generation, natural gas, the nuclear industry, boiler manufacturing, vehicle production, fitness equipment, and sporting goods. Below, the experts at Huameng Machinery outline the key components of these pipe bending machines.

1. Fully automatic pipe bending machine – machine frame: The frame features a main spindle assembly welded from channel steel, with the upper and lower spindle bearing support plates—made of 15mm thick steel—mounted within the frame.

2. System component: The hydraulic system may utilize either commercial-grade or aircraft-grade hydraulic components.

3. Transmission assembly: The transmission assembly consists of a hydraulic cylinder, a rack, a gear, and a drive shaft.

4. Mold Section: The mold section consists of auxiliary tools fabricated to match various profile diameters; these are made from bearing steel or roll steel and heat-treated to a hardness of HRC 48–52.

5. Clamping section: The hydraulic clamping section consists of a slide plate, a rocker arm, and a hydraulic cylinder; the extension and retraction of the cylinder drive the movement of the rocker arm.

6. Electrical components.

1. Structure and working principle of fully automatic pipe bending machine and electric hydraulic pipe bending machine (electric pipe bending machine): It consists of an electric oil pump, high-pressure oil pipe, quick coupling, working cylinder, plunger, and bending components including upper and lower perforated plates, die head, and rollers. The power output is provided by the electric oil pump.

High-pressure oil is delivered through a high-pressure line into the working cylinder, where it drives the internal plunger to generate thrust, thereby bending the pipe via the bending assembly.

2. Applications of the electric-hydraulic pipe bending machine (electric pipe bender):

The fully automatic pipe bender is suitable for pipe installation and repair work in factories, warehouses, docks, construction sites, railways, and the automotive industry. In addition to its pipe-bending function, the bending assembly (hydraulic cylinder) can be detached and used as a separate hydraulic jack.
