Multi-axis linkage metal wire torsion test device

Abstract

The invention provides a multi-axis linkage metal wire torsion test device. The device comprises a T-shaped bedplate, a controller, a gear motor, a servo motor and a transmission mechanism which are arranged on a rack. The controller controls the gear motor to rotate through the servo motor. The transmission mechanism is driven by the gear motor. The device further comprises a position fixing base, a constant-tension tensioning device, a sliding end steel wire clamping module and a connecting rope positioning module. The transmission mechanism comprises a driving gear and a plurality of drivengears. The sliding end steel wire clamping module comprises a sliding plate and a plurality of three-jaw chucks movably fixed to the sliding plate. The connecting rope positioning module comprises apositioning plate, and the constant-tension tensioning device comprises a plurality of connecting ropes, a directional wheel and weights. The torsion test precision and efficiency can be improved on multiple levels, the test period is shortened, and the economic benefit is improved.

Description

technical field [0001] The invention relates to a torsion test device, in particular to a multi-axis linkage metal wire torsion test device. Background technique [0002] Metal wire rods must undergo detailed quality testing before they can enter the market, and the torsional fatigue strength is an important indicator of its inevitable testing. The torsional performance is related to the service life of the steel wire, and has a great influence on the yield of the subsequent rope-making process. Practice has proved that most of the fractures during the twisting process are caused by the torsion performance of the metal wire not meeting the required material toughness. of. In the detection process, the torsion test is an important method to effectively evaluate the torsion performance of the metal wire. The torsion test can reflect the deformation capacity and toughness of the sample. Under the same conditions, a large number of torsion circles of the sample indicates that ...

Problems solved by technology

However, there are many problems in the current wire torsion test system: a) only a single metal wire can be tested, and the test efficiency is low; b) the coaxial accuracy of the steel wire needs to be manually adjusted during the test, and the steel wire clamp must be manually assembled to ensure the clamping force Human control is required, and the influence of random response on the test results cannot be controlled, and the repeatability is poor; c) There is no automatic counting device, and there are random factors in manual counting; d) The test system has poor adaptability to metal wires with different diameters; e) The clamping and installation of the wire basically needs to be done manually, and the test process is time-consuming and laborious
