Description

Technical Field

[0001] The invention belongs to the technical field of electric power system test tools, in particular to a wire crimping instrument and a crimping method. Background Art

[0002] As an important part of the transmission line, the manufacturing quality and installation quality of the conductor affect the safe and stable service of the transmission line. The traditional wire crimping method usually relies on manual tools such as pliers. This method is not only time-consuming, but also difficult to ensure the consistency and quality of each crimping. In addition, for wires of different specifications, different crimping dies need to be replaced, which increases the difficulty of operation.

[0003] The main reasons for the problem of wire crimping are as follows: First, the crimping tool is not suitable: using the wrong crimping tool or mold cannot match the specifications and type of the wire; the crimping tool is damaged or worn, resulting in uneven crimping force; second, the crimping force is insufficient or excessive: insufficient crimping force will lead to loose crimping, increased resistance at the connection, and severe heat; excessive crimping force may damage the wire, causing internal fractures or damage to the insulation layer; third, the crimping point is improperly positioned: the crimping point deviates from the center of the wire, resulting in uneven crimping; the crimping point is too close or too far from the end of the wire, affecting the stability of the connection; fourth, the operator's skills are insufficient: the operator lacks the necessary training and is unfamiliar with crimping technology and standards; lack of concentration during operation leads to crimping errors; fifth, insufficient inspection after crimping: no sufficient inspection is carried out after the crimping is completed, such as visual inspection, tensile test, etc.; the crimped wires are not subjected to necessary protective treatment, such as waterproofing and dustproofing.

[0004] Therefore, it is particularly important to develop a device that can quickly adapt to different wire specifications while ensuring crimping quality and efficiency.

[0005] The main problems faced:

[0006] Different wires have different models and different matching hardware, which leads to certain particularities in the crimping of each batch of wires. In order to ensure the smooth progress of the inspection work, the most important thing is to find an effective method to accurately crimp the wires and ensure the crimping quality. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a wire crimping instrument and a crimping method, which can quickly crimp wires and hardware of different models, effectively ensure the crimping quality, reduce operation risks, improve detection standardization, and ensure the crimping quality.

[0011] Furthermore, the power system provides the crimping force in an electric or pneumatic manner.

[0012] The second aspect of the present invention is to provide a crimping method of the crimping instrument, firstly identifying different types of wires and hardware, placing the matching crimping die into the crimping instrument, and the crimping instrument uses the extrusion of the power system to extrude the hardware and the wire according to the standard requirements.
