The oil pump is immersed in hydraulic oil inside the oil tank for cooling and noise dampening. The oil pump is driven by electric motor and the hydraulic oil is pumped out and pushed by the plunger in the oil tank. As a result, the die set compresses in a radial direction and crimps the hose connector. When the amount of compression reaches the predetermined value, the compression will automatically stop. Then the magnetic reversing valve switches the direction and the plunger moves backwards. As a result, the die set expands and the hose crimping process is finished.
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 highly pressure resistant, tear resistant with great impact absorbing strength and carrying capacity. Therefore, the oil tank and piston rod are more durable.
Our crimping dies are connected through magnetism, which make it convenient for assembly and disassembly. Also the magnetic connection enables automatic positioning, and the crimping is neat and nice. The dies are made from Cr12 die steel. (Cr12 die steel is a type of classic alloy tool steel.)
Hydraulic conduction system:
With the pipeless valve block connection, the hydraulic conduction system is oil tight and durable with little heat buildup, stable pressure conduction, great longevity, and greatly improves the performance of the crimping machine.
