Description
The YONG-FENG F16 steel tube crimping machines are used for crimping steel and iron tubes. Using a Rexroth hydraulic unit, the YONG-FENG F16 crimper is small, lightweight and easy to operate. The oil pipelines are specially designed, and the crimper is efficient and reliable.

• The YONG-FENG F16 steel tube crimping machine can completely replace manual welding.
• The positioning device solves problems arising from the different reducing diameters in steel and iron tubes.
• The die stroke is improved and the productivity is greatly enhanced, with a daily production of 3000-5000 tubes.
• The crimper is small, and takes up very little space. It is also easy to move.
• The customized dies are very precise. Therefore, there will be no cracks in the steel and iron tubes after processing completion.

Details

The oil cylinder cover, oil tank and piston rod are made of 40 chromium, with a surface hardness of HRC26-30 and an operation layer hardness of HRC59-63. The hardened layer is 2mm thick. The 40 chromium is high pressure resistant and tear resistant with a great impact absorbing and carrying capacity. Therefore, the oil tank and piston rod are more durable.

With the pipeless valve block connection, the hydraulic conduction system is oil tight and durable with very little heat, stable pressure conduction and great longevity, and greatly improves the performance of the crimping machine.

Our crimping dies are connected through magnetism, which make it convenient for assembly and disassembly. The magnetic connection allows for automatic positioning, and the crimping is neat and nice. The dies are made of Cr12 die steel. (Cr12 die steel is a classic alloy tool steel.)

Operation
The oil pump is immersed in the hydraulic oil inside the oil tank for cooling and silence. The oil pump is driven using electric motor and the hydraulic oil is pumped out and pushed using the plunger in the oil tank. As a result, the die set compresses in a radial direction and crimps the hose connector. When the compression amount reaches the predetermined value, the compression will automatically stop. The magnetic reversing valve then switches direction and the plunger moves backwards. As a result, the die set expands and the hose crimping process is finished.
