Abstract

A non-casting steel wire rope tensile test clamping device is composed of a rack, a front clamping device, a moving cross beam, a force measuring device, clamping piece bases, clamping pieces and a rear clamping device. The front clamping device and the rear clamping device are arranged on the rack and are provided with the clamping piece bases and the clamping pieces; the rack is provided with the moving cross beam and the force measuring device. A hydraulic clamping mode and a hydraulic loosening mode are adopted for the clamping devices, clamping force is 5-15 Mpa, openings of the clamping pieces are in the shape of V, inclined lines staggering at 60 degrees are arranged on the surfaces of the clamping pieces, a small-inclination chamfer angle larger than 20 mm is formed at the tail end of each clamping piece, it is guaranteed that a steel wire rope is not damaged in a clamping mode, slippage is also avoided, the clamping piece bases are assembled on a clamping plate according to 15-degree wedge angles, friction between the clamping piece bases and the clamping plate is reduced, clamping is reliable, self-locking is prevented, and replacement of the clamping pieces is facilitated.

Description

technical field [0001] The invention relates to a clamping device for a tensile test of a non-casting steel wire rope, belonging to the technical field of mechanical performance testing equipment. Background technique [0002] The metal product testing organization adopts the methods of wire rope binding, calibration distance, loose ends, cleaning, hot casting or cold casting, cooling, and testing for the breaking test of steel wire ropes with a diameter of 18mm to 44mm. The sample production process is complicated, time-consuming and expensive. high. By designing a set of tensile test clamping device, the existing test method of clamping and stretching by casting the end of the steel wire rope is changed, the test process is optimized, and the steel wire rope sample is directly clamped and tested on the testing machine. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a non-casting steel wir...
