**Folding Machine for Staggered Type Fin Evaporator**
**Product Composition and Structure**
The folding machine is designed for manufacturing staggered type fin evaporators. It consists of several key components: a workbench, tension device, folding mechanism, length adjustment system, and an electric control unit. The entire operation is driven by hydraulic cylinders, while the electrical system is controlled via relays.
I. **Workbench**: Constructed from square tubes and welded steel plates, it includes two pneumatic joints and an air valve group to support the overall structure and manage air pressure during operations.
II. **Tension Device**: This part includes a tension cylinder, a dead plate, guide components, and tension dropheads. It ensures that the pipes are properly stretched before folding.
III. **Folding Device**: Composed of a folding cylinder, mounting plate, two reverse head racks, and diagonal making heads. The diagonal making cylinder drives the axles in the diagonal making heads through a gear rack system. As the axles rotate in opposite directions, the pipes can be bent diagonally as required.
IV. **Length Adjustment Device**: Made up of a lead screw, feeding box/sliding box, base, bearing pedestal, locknut, and hand wheel. The bearing pedestal is integrated with the guide component, and the tension cylinder is mounted on the feeding box base. By turning the hand wheel, the distance between the tension dropheads and folding heads can be adjusted precisely.
V. **Electric Control System**: The low-voltage components are equipped with Schneider brand parts, ensuring reliable and safe operation.
**Equipment Operating Instructions**
Before starting the machine, adjust the distance between the tension dropheads and the folding heads using the lead screw according to the desired product size. Insert the pre-diagonally processed single chips into the 3R module. Step on the foot pedal to activate the tension cylinder, which lifts the dropheads and stretches the pipes.
Next, the folding cylinder engages, rotating the folding axles via the gear rack. The two round ends of the single chips are rotated at 60° and 120° respectively in a 1:2 ratio in opposite directions. Once the folding is complete, the tension cylinder retracts to release the pipes, followed by the folding cylinder returning to its original position. At this point, the finished workpieces can be manually removed.
**Equipment Maintenance**
Only trained operators should handle the equipment. Regular maintenance is essential for optimal performance and safety.
1. Ensure the compressed air pressure is maintained at 0.5–0.8 MPa.
2. Lubricate the friction surfaces between the rack and guide box, as well as between the linear bearings and guide rods of the tension dropheads, once per shift.
By following these guidelines, the machine will operate efficiently and last longer. Proper care not only improves productivity but also enhances the working environment and reduces the risk of mechanical failure.
