Problems solved by technology

However, in the traditional tensile test, it is necessary to manually operate the clamp to clamp the bead wire. This method is prone to slippage with the clamp during the detection of the bead wire, resulting in inaccurate detection data.

Embodiment Construction

[0013] The technical solutions of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0014] ginseng figure 1 As shown, the tensile test detection fixture includes a main body 4, the lower end of the main body 4 is fixed with a fixed block 10 and a limit block 9, an action space is formed between the fixed block 10 and the limit block 9, wherein the limit block 9 There are screw holes.

[0015] A chuck 8 is provided in the actuating space, and the side of the chuck 8 facing the fixed block 10 is a clamping surface. The clamping surface is set in a corrugated (teeth-like) shape, and the material of the chuck 8 is preferably 06Cr19Ni10 stainless steel , which can prevent the bead wire from slipping on the chuck during the tensile test.

[0016] A threaded rod 7 is rotatably provided in the screw hole of the limit block 9, one end of the threaded rod 7 is fixed to the chuck 8, and the other ...

Abstract

The invention discloses a detection fixture for tensile testing of steel wires, wherein the detection fixture comprises a main body part, a fixed block, and a limiting stopper, wherein the fixed block and the limiting stopper are fixed and oppositely arranged on the main body part; an actuating space is formed between the fixed block and the limiting stopper; a clamping head is arranged in the actuating space; a gripping surface is arranged on one side of the clamping head, facing to the fixed block; the gripping surface is corrugate; a screw hole is formed in the limiting stopper; a threaded rod is rotationally arranged in the screw hole; one end of the threaded rod is fixed with the clamping head, and an adjusting handle is fixed at the other end of the threaded rod. According to the detection fixture for tensile testing of the steel wires, a transitional tensile design is adopted, so that the phenomenon that broken ends of steel wires of fine sizes in the tensile testing are positioned in the fixture is avoided to not give rise to invalid testing results; besides, the clamping head adopts toothed and wear-resisting stainless steel design, so that the steel wire is prevented from slipping when clamped by the fixture in the process of tensile testing.

Description

technical field [0001] The invention relates to the technical field of bead wire detection equipment, in particular to a tensile test detection fixture. Background technique [0002] The bead wire needs to go through four major processes in the preparation process: rough drawing, heat treatment, middle wire drawing and tempering copper plating. After each process, it is necessary to perform a tensile test on the bead wire to detect technical indicators such as the maximum load-bearing tensile force and elongation deformation of the bead wire. However, in the traditional tensile test, it is necessary to manually operate the clamp to clamp the bead wire. This method is prone to slippage with the clamp during the detection of the bead wire, resulting in inaccurate detection data. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a testing fixture device for a tensile machine, the steel wire is not easy ...
