Schematic diagram of the working principle of crimping pliers?
Crimping pliers are necessary tools for wire connection and crimping in the power industry in line construction and line maintenance.
Crimping pliers are 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 and a pair of It is composed of a high-pressure oil pump and a low-pressure oil pump. The oil pump body is suspended on the oil tank cover. The high and low pressure oil outlet holes are opened on the oil pump body and are connected to the oil circuit of the pressure relief valve. The eccentric shaft is arranged longitudinally, and the upper end is pivoted on the oil pump body. The eccentric bearing is fixed at the center and the lower end, the driven gear is fixed on the top of the eccentric shaft, and is connected with the power mechanism. The high and low pressure oil pumps are suspended on the oil pump body. The pump cavity of the oil pump is communicated with the high and low pressure oil outlet holes respectively. Advantages: The connection between the pump oil mechanism and the power mechanism is a vertical connection, which can make full use of the space and reduce the floor space, which is beneficial to operation and transportation; the pump oil form of the high and low pressure oil pumps is changed into the actuation form of the eccentric bearing, The utility model has the advantages of simple structure and few parts, which is convenient for assembly.
The jaws of the compression pliers consist of a fixed arm and a movable arm. The lower part of the moving arm is set on a bar. The rotation of the screw is controlled by the worker with a shake. It is a labor-saving lever principle that the worker turns the crank handle, and the lead screw drives the change of the tension of the jaws to use the slope labor-saving principle.
