Abstract

The invention discloses a wire and cable torsional tensile testing machine, which comprises a column frame, a lifting module, a torsion module, a clamp, a cable fixing assembly, an electrical box and a programmable electrical control system, and guide rails are arranged on the column frame. The lifting module includes a lifting motor and a reducer, a driving sprocket assembly and a driven sprocket assembly; the torsion module includes a torsion motor, and the torsion motor is arranged on the top of the skateboard support frame; the lower end of the torsion motor is provided with a clamp. It includes a three-jaw chuck and a chuck gripper; the control system is arranged at the lower rear wall end of the column frame. The invention makes the wire and cable test more stable by setting the three-claw clamp, and accurately detects the on-off performance of the conductor when it is stretched and twisted by setting a perfect control system, provides effective power-off and overload protection, and makes the equipment work more efficiently. Precise and safe.

Description

technical field [0001] The invention relates to a testing machine, especially a torsional movement tensile testing machine for electric wires and cables. Background technique [0002] The driving of electric vehicles is mainly driven by electric energy, and the electric energy is mainly charged and stored through charging pile devices. The car charging interface and the charging pile device are connected and charged through the charging pile cable. The charging pile cable will be irregularly twisted and stretched during its use, and it is prone to damage, which will cause charging failure and even cause safety hazards. At present, there is no relevant use environment simulation test for charging pile cables in China to help life verification standards. Wires and cables are subject to long-term moving stretching and twisting, so it is necessary to test their tensile and twisting properties to determine their service life. [0003] Tensile tester refers to a test device for...
