Zhongtuo Cold Bending’s newly developed diamond-shaped interlocking pipe fence forming machine has successfully passed testing and is about to be shipped to Europe. This equipment integrates several core patented technologies, including a “front flat plate cutting forming + rear positioning hydraulic cutting” process that ensures smooth, burr-free, and deformation-free cut surfaces while guaranteeing high-speed continuous production. Its unique “horizontal roller + vertical roller + 45° inclined conical roller” combined roller system design ensures flat sheet forming, clear edges, and zero damage to the surface coating. The machine’s precise interlocking structure, strong connections, and excellent overall performance have earned high recognition and praise from European customers, further demonstrating Zhongtuo Cold Bending’s innovative strength and technological advantages in the high-end cold bending forming equipment field.

Its main features include:
1.High Sealing Performance:
The diamond-shaped locking joint design ensures tight seam interlocking, effectively preventing cement slurry leakage.
2.High tensile strength:
The locking joint structure enhances the overall mechanical performance of the pipe body, making it suitable for high-pressure environments.
3.High automation level:
Most models are equipped with PLC control systems, achieving full automation from feeding to forming.
4.Wide range of applicable materials:
Capable of processing various materials such as galvanized steel strips and cold-rolled steel strips, with thickness typically ranging between 0.25~0.5mm.
5.Fast molding speed:
Depending on the model, the line speed can reach 10 to 30 meters per minute.
The diamond shaped lock mouth pipe forming machine is mainly used in engineering fields that require high-strength and high sealing metal corrugated pipes, especially playing a key role in prestressed concrete structures. Its core application scenarios include:
1. Bridge engineering
• A protective sleeve used for manufacturing prestressed steel bars to prevent steel corrosion and ensure effective transmission of tension force.
• Widely used in large-span structures such as high-speed railway bridges and highway overpasses.
2. Construction of highways and tunnels
• Laying prestressed tendon channels in prefabricated components such as box girders and T-beams.
• Provide a stable pipeline environment to avoid cement slurry infiltration during pouring.
3. High rise buildings and large public facilities
• Prestressed floor slabs and beams used in large space buildings such as sports arenas, airports, and convention centers.
• Enhance structural crack resistance and load-bearing capacity.
4. Electricity and communication infrastructure
• Some models can be used for the manufacturing of cable protection pipes, especially in underground utility tunnels.
• Diamond shaped lock mouth design enhances compressive and waterproof performance.
