Composition Overview
1
The semi-automatic long U-bending machine consists of a feeding rack, bending device, unloading device, mandrel device, electrical system, and pneumatic system. The action cycle is as follows: manual feeding of cut-to-length straight pipes into position → pipe clamping → oil mist spraying and bending → mandrel withdrawal → pipe clamping release → unloading → unloading reset (with manual material retrieval simultaneously) → bending reset.
2
Feeding Rack Device
2.1 The feeding rack is used when the bending length is ≥ 800mm.
2.2 The feeding rack adopts pinhole positioning, enabling easy installation without adjustment.
2.3 The feeding rack is telescopic and adjustable to adapt to pipes of different sizes.
3
Bending Device
3.1 Driven by a hydraulic cylinder, bending is performed through a rack-and-pinion transmission structure.
3.2 Equipped with an oil mist lubrication function for bending dies during operation, which extends the service life of the bending dies and improves the quality of bent pipes.
3.3 The integral bending die base is processed and formed in one piece, featuring high rigidity and precision.
3.4 The supporting die and clamping die are controlled by hydraulic cylinders.
3.5 The bending die, clamping die, and supporting die are made of alloy steel, undergo integral quenching, and are precision-machined by CNC equipment, ensuring wear resistance and high precision.
4
Unloading Device
4.1 Unloading of workpieces is achieved by a servo-controlled stripping pipe.
4.2 Simple structure and convenient process control.
5
Mandrel Device
5.1 Mandrel withdrawal is controlled by a hydraulic cylinder.
5.2 The mandrel rod support plate adopts a buckle connection and automatically separates during sliding.
5.3 The length of each mandrel rod is adjustable.
6
Electrical System
6.1 The electrical cabinet is built-in, and the operation box is a wall-mounted type.
6.2 The machine adopts integrated control of PLC, human-machine interface (HMI), and related electrical components, ensuring convenient and efficient operation.
7
Hydraulic System
7.1 Independent hydraulic station.
7.2 Hydraulic working pressure: 7MPa (±10%).
