Description

Technical Field

[0001] The utility model relates to the technical field of crimping machines, in particular to a steel core aluminum stranded wire crimping machine. Background Art

[0002] The outside of the steel core aluminum stranded wire is made of aluminum wire wrapped around the steel core by twisting; the steel core mainly serves to increase the strength, and the aluminum stranded wire mainly serves to transmit electrical energy. The crimping machine is a necessary tool for the power industry to perform conductor crimping during line infrastructure construction and line maintenance.

[0003] According to the description of a crimping machine disclosed on the patent website (authorization announcement number: CN 219937563 U), "The utility model relates to the technical field of crimping machine devices, specifically a crimping machine. It includes a housing assembly, a positioning assembly, and a crimping assembly. The housing assembly includes a body shell. The crimping assembly includes a crimping bottom block and a crimping top block. A connecting groove is provided on the inner side of the crimping bottom block. One end of the crimping bottom block is connected to an extrusion middle plate. The end of the extrusion middle plate away from the connecting block is connected to a supporting layer. The end of the supporting layer away from the extrusion middle plate is connected to a crimping card strip. Through the setting of the crimping card strip, it is used to directly make extrusion contact with the terminal. At the same time, the crimping card strip is deformed by the reverse force of the terminal when the terminal is squeezed. Then, the crimping card strip can be deformed to make the internal force of the terminal form a bulge, thereby increasing the friction between the terminal and the wire. The spacing between two adjacent crimping card strips is the same, and space for the crimping card strip to deform is provided."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, due to the operation of the telescopic rod being turned on, the telescopic rod is extended and operates, and a force is exerted on the crimping top block to gradually move it closer to the crimping bottom block, and then until the crimping top block presses the terminal, thereby fixing the terminal on the wire. However, in actual use, it is not convenient to disassemble and replace the crimping top block and the crimping bottom block according to actual conditions, and it has certain limitations. In addition, when the telescopic rod drives the crimping top block to move downward, it will be accompanied by a huge impact force, which is not convenient for buffering and protecting the telescopic rod and the crimping top block. Therefore, it is necessary to improve a steel core aluminum stranded wire crimping machine to solve the above problems. Utility Model Content
