A high-voltage and high-current coaxial cable joint pressing device

Abstract

The invention discloses a high-voltage and high-current coaxial cable joint press-fit device, which comprises a hydraulic energy mechanism and a press-fit mechanism. The hydraulic energy mechanism andthe press-fit mechanism are separately arranged. The energy of the hydraulic energy mechanism is supplied to the press-fit mechanism. The hydraulic energy mechanism comprises a fixed pressure head (9) and movable pressure heads (10). The fixed pressure head (9) is coupled to a piston rod on an oil cylinder (8). An electromagnetic reversing valve is arranged at the connection part of the piston rod and the oil cylinder (8). The fixed pressure head (9) comprises a plurality of identical sector-shaped connecting members. A sector-shaped groove is arranged at one side of a small arc side of eachsector-shaped connecting member. The number of movable pressure heads (10) is several. Each movable pressure head has a sector-shaped protrusion at one end and a sector-shaped structure at the other end, and the sector-shaped protrusion is snap-fitted with the sector-shaped groove. The inner sides of the sector-shaped structures of the several movable pressure heads constitute a press-fit inner circle. The high-voltage and high-current coaxial cable joint press-fit device of the invention realizes accurate press fitting.

Description

technical field [0001] The invention belongs to the technical field of coaxial cable production equipment, and more specifically relates to a high-voltage and high-current coaxial cable joint pressing device. Background technique [0002] With the development of the economy and the improvement of people's living standards, cables are widely used in our lives. Among them, coaxial cables are widely used in the field of high-voltage and high-current power transmission, and the manufacturing process of coaxial cables has gradually attracted the attention of the outside world. Since the cable needs to be used for a long distance, in order to connect the multi-section lines into a whole, the cables will be crimped. The quality of the cable joint is directly related to whether the cable can run safely, and a little carelessness will cause failure, and even cause serious loss of life and property.

The quality of the cable joint is directly related to whether the cable can run safely, and a little carelessness will cause failure, and even lead to serious loss of life and property

[0003] At present, there are two methods of crimping cable joints. One is manual crimping. Manual crimping needs to grasp the shrinkage of the mold based on experience, which is not only low in efficiency but also low in precision; the other is crimping on a hydraulic machine. Put the cable joint and wire lug into the special crimping device, and the pressure is provided by the hydraulic press for crimping

Work directly on the hydraulic machine, without a special control mechanism for press-fitting, press-fitting is difficult to control. At the same time, there are many types of cables, that is, each type of cable needs to design a professional crimping device for crimping, so that the crimping Device design and manufacturing costs are high

In addition, it is difficult to control the shrinkage of the mold during the crimping process of the crimping device, resulting in low compression accuracy and difficult to meet the requirements of precise crimping
