TECHNICAL FIELD

[0001] The utility model relates to a whole circle device field especially a full -automatic oil press whole circle device. BACKGROUND

[0002] The oil press utilizes hydraulic oil as the working medium, converts mechanical energy into hydraulic energy through the hydraulic pump, and then transmits the hydraulic energy to the oil cylinder or piston through the hydraulic pipeline, thereby realizing the transmission and conversion of energy. The oil press performs accurate whole circle processing on the pipe material through its hydraulic transmission system and mold, so that the pipe material reaches the required roundness. The oil press whole circle device is a device specially used for bending and forming metal plates or pipes to achieve a circular shape or other complex shapes. It is usually integrated in the oil press system and realizes high-precision forming operation through hydraulic power. The oil press whole circle device provides uniform pressure distribution through the hydraulic system, avoiding local stress concentration and ensuring the quality and consistency of the product. The hydraulic pump pressurizes the oil and transmits it to the forming mold through the hydraulic cylinder, generating strong forming force. The whole circle steel pipe can provide higher efficiency, reliability and safety in actual application, while reducing production cost and prolonging service life.

[0004] When the oil press whole circle device is in use, it is inconvenient to adjust the whole circle pressure according to the inner diameter of the steel pipe when whole circle of steel pipes with different inner diameters is performed.
