Embodiment Construction
[0014] The wire stretching clamp of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0015] See figure 1 , A wire stretching clamp of the present invention includes a clamp body 1, a locking screw 2 and a metal cap 3. The clamp main body 1 is provided with a stepped central hole with three large, medium and small diameters for sequential installation of the locking screw 2 and the metal cap 3, and the large diameter section is also provided with a threaded hole that matches the locking screw 2; the clamp main body 1 The outside is a cylinder composed of large and small diameters. There is a circular arc transition between the large and small diameter cylinders. The outer cylinder corresponding to the small diameter section of the stepped center hole is provided with a convex circle 5 with a triangular cross section and is along the axial direction. There is a slot 4 for putting the metal cap 3 into it. The locking ...

The invention discloses a wire stretching clamp, which comprises a clamp body, a locking screw and a metal cap. The interior of the clamp body is provided with step central holes with large, medium and small diameters for mounting the locking screw and the metal cap in turn, wherein the large diameter section is also provided with a threaded hole matched with the locking screw; and the exterior of the clamp body is a column body with large and small diameters, an arc transition is arranged between a large diameter section and a small diameter section of the column body, the outer column body corresponding to the small diameter section of the step central hole is provided with a dome with a triangular section and axially provided with a groove convenient for putting the metal cap. The clamp can effectively prevent a sample from slipping and abnormally breaking, can measure stretching mechanical properties of wires of common metal materials, shape memory alloy and the like under the conditions of normal temperature, high temperature and the like, has accurate and reliable test results, and simultaneously has the advantages of simple structure, easy manufacture, low cost and practicability.
Description
Technical field [0001] The invention relates to a material stretching clamp, in particular to a wire stretching clamp. It belongs to the technical field of fixture design and manufacturing. Background technique [0002] Tensile testing is a common method for testing mechanical properties of materials. There are many types of tensile clamps attached to material testing machines. The mechanical properties of wire rods are usually measured by winding or wedge-shaped or clamp-type clamps for sample clamping. However, for metal or alloy wires with a diameter of less than 5mm, due to their small monofilament diameter, the existing clamps are not perfect, and the clamping effect is not good. Often, the sample slips or breaks in the clamping part. [0003] In addition, when measuring the non-room temperature mechanical properties of the wire, such as high temperature mechanical properties and creep, or measuring the shape memory effect and superelastic properties of shape memory alloys, i...
