What is the use method of hydraulic crimping tool? What are the classification of hydraulic crimping tools?

Hydraulic crimping pliers are one of the hydraulic tools. With hydraulic crimping pliers, we can connect very thick cables together, but it is difficult to complete with ordinary crimping pliers. Hydraulic crimping pliers. The hydraulic crimping pliers mainly rely on the hydraulic transmission mechanism to generate pressure to achieve the purpose of crimping the wires, which are used to crimp the strands of aluminum or copper cores of more than 35mm. So what is the use method of hydraulic crimping tool?

Hydraulic crimping pliers are a type of hydraulic tools. The main feature is the use of hydraulic principles to generate strong pressure to complete the riveting and crimping of very thick steel cables, cables, and high-voltage wires. The hydraulic crimping tool is composed of an oil tank, a power mechanism, a directional valve, a pressure relief valve, and an oil pump mechanism. The oil pump mechanism is composed of an oil pump body, high and low pressure oil outlet holes, an eccentric shaft, an eccentric bearing, a 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 connected to the oil path of the pressure relief valve. In the center, an eccentric bearing is fixed at the lower end. The driven gear is fixed on the top of the eccentric shaft and is connected to the power mechanism. The high and low pressure oil pumps are suspended on the oil pump body, and each has an actuator that contacts the eccentric bearing. The pump cavity of the oil pump communicates with the high and low pressure oil outlet holes respectively.

How to use hydraulic crimping tools

1. First check whether the crimped terminal matches the wire specification.

2. Select the mold to be pressed. For example, the terminal size to be pressed is 240mm2, then select the upper and lower molds of 240mm2.

3. Put the mold into the piston and mold fixing seat.

4. How to use the Hydraulic Pump: tighten the feed and return switch clockwise and shake the handle repeatedly to watch the mold. When the upper and lower mold touch one place, it means that the pressing is completed. If the user does not pay attention to continue to shake, the pump There is a click sound in Pu, this is the safety protection device is opened, the piston stops advancing, at this time the oil return switch should be turned counterclockwise, then the piston returns to the original position. Note: The mold cannot be compressed without being installed. To avoid damage to the piston and jaws.

Classification of hydraulic crimping pliers

1. Manual hydraulic crimping pliers: use hydraulic transmission mechanism to generate pressure, crimping the terminal and cable is an essential tool for electrical installation engineering.

2. Split hydraulic crimping pliers: The split hydraulic crimping pliers head is used in conjunction with the pedal hydraulic pump, which is widely used in high-altitude operations, crimping overhead wires, wire repairs and other operations.

The above is an introduction to the use, introduction and classification of hydraulic crimping tools. Hydraulic crimping tools are usually mainly used in cable connection. The appearance of hydraulic crimping tools makes wiring more time-saving and labor-saving. The classification of hydraulic crimping pliers is different, and there are many specifications. When choosing, you must make targeted selections according to the actual situation.
