It is composed of oil tank, power mechanism, directional valve, pressure relief valve, and pump oil mechanism. The pump oil mechanism is composed of oil pump body, high and low pressure oil outlet holes, eccentric shaft, eccentric bearing, driven gear, two high-pressure oil pumps, and one low-pressure oil pump. The oil pump body is generally suspended on the oil tank cover, and the high and low pressure oil outlet holes are opened on the oil pump body and connected to the pressure relief valve oil circuit. The eccentric shaft needs to be longitudinally set, The upper end pivot is placed in the center of the oil pump body, and the lower end is equipped with and fixed with an eccentric bearing. The driven gear is fixed at the top of the eccentric shaft and connected to the power mechanism. The high and low pressure oil pumps are suspended on the oil pump body, each with an actuator in contact with the eccentric bearing. The pump chambers of the high and low pressure oil pumps are respectively connected to the high and low pressure oil outlet holes.
Advantages of the crimping machine: The connection between the pump oil mechanism and the power mechanism is vertical, which can fully utilize space and reduce the occupied area, which is beneficial for operation and transportation; Transforming the pump oil form of high and low pressure oil pumps into the action form of eccentric bearings has a simple structure, fewer components, and is conducive to assembly.
