Crimp machine structure

It is composed of oil tank, power mechanism, reversing valve, pressure relief valve and oil pump mechanism. The oil pump mechanism consists of oil pump body, high and low pressure oil outlet holes, eccentric shaft, eccentric bearing, driven gear, a pair of high pressure oil pumps and a Composed of low-pressure oil pump, the oil pump body is suspended on the fuel tank cover, the high and low pressure oil outlet holes are opened on the oil pump body, connected with the oil circuit of the pressure relief valve, the eccentric shaft is vertically arranged, the upper end is pivoted in the center of the oil pump body, and the lower end is fixed An eccentric bearing is set, the driven gear is fixed on the top of the eccentric shaft, and connected with the power mechanism, the high and low pressure oil pumps are suspended on the oil pump body, and each has a moving part in contact with the eccentric bearing, the pump chamber of the high and low pressure oil pumps They communicate with the high and low pressure oil outlets respectively. Advantages: The connection between the oil pumping mechanism and the power mechanism is vertical, which can make full use of the space and reduce the floor area, which is beneficial to operation and transportation; the oil pumping form of the high and low pressure oil pumps is changed to the actuation form of the eccentric bearing, The utility model has the advantages of simple structure and few parts, which is convenient for assembly.
