Tension test device and test method for copper wires

Abstract

The invention discloses a tension test device for copper wires. The device comprises a test platform, a transfer device, a copper wire fixing assembly, a stretching device and a tension metering device. The test platform is arranged at the lowest end; the transfer device and a transfer rail are correspondingly arranged; the copper wire fixing assembly and the transfer device are correspondingly arranged; the stretching device is arranged corresponding to the stretching rail; the tension metering device is used for metering a tension value of the copper wire in a stress disconnection process; and the transfer rail is arranged on the test platform, and the transfer device is introduced so that the plurality of transfer devices can be sequentially arranged and transferred, and a continuous tension test on the copper wires is facilitated. Besides, an independent structure convenient to assemble and disassemble is arranged between the copper wire fixing assembly and the transfer device so that the copper wire can be fixed and erected on the transfer device in advance, and preparation is made for a tension test.

Description

technical field [0001] The invention relates to the technical field of metal wire index detection, in particular to a tensile test device and a test method for copper wires. Background technique [0002] Copper wire refers to the thin wire drawn from thicker copper wire, which can be used for wire cutting wire, cable wire, copper brush filter, etc. It is widely used in wire cutting and power transmission. In the process of use, the wire will inevitably be subjected to various bending and pulling according to the needs. Therefore, the tensile strength of the copper wire is a very important performance index for the copper wire. [0003] In the prior art, the copper wire is generally tested for the strength of the copper wire by a tensile testing instrument, although the copper wire tensile testing instrument can automatically obtain the maximum test force, breaking force, yield force, tensile strength, compressive strength, bending strength Strength, elastic modulus, elongat...
