Hydraulic cone rolling machine is used to bend a certain thickness of metal plate into a cone-shaped or tapered part at room temperature. Its working principle is rotational bending deformation. Due to the vertical adjustment of the upper roller, there is no need for additional equipment such as a press. It can be loaded in one go and can complete the forming and bending function of the two ends of the sheet metal without the need to turn the head. It is also used for correcting the formed workpiece. It is an essential equipment for manufacturing machinery and equipment in industries such as petroleum, chemical, cement, shipbuilding, boilers, aviation, water conservancy, and power transmission and transformation towers. This machine has a compact structure and is easy to operate, making it currently one of the better rolling machines in China.
