Crimping Machine Structure

Composed of an oil tank, a power mechanism, a directional valve, a pressure relief valve, and a pump oil mechanism, the pump oil mechanism consists of an oil pump body, high and low pressure oil outlet holes, an eccentric shaft, an eccentric bearing, a driven gear, a pair of high pressure oil pumps, and a low pressure oil pump. The oil pump body is 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 is arranged longitudinally, with its upper end pivotally placed in the center of the oil pump body and its lower end fixed with an eccentric bearing. The driven gear is fixed on 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 that contacts 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: The connection between the pump oil mechanism and the power mechanism is vertical, which can make full use of space and minimize the footprint, facilitating operation and transportation. The pump oil form of the high and low pressure oil pumps is changed to the actuation form of the eccentric bearing, which has a simple structure, fewer components, and is conducive to assembly.
