Description

Technical Field

[0001] This utility model relates to the field of metal wire winding test technology, specifically to a fixture for metal wire winding test. Background Technology

[0002] Metal wires, such as steel wire, copper wire, and aluminum wire, are important industrial raw materials widely used in wire ropes, springs, cables, welding wires, and other fields. Their mechanical properties, especially their plastic deformation capacity, directly affect the quality, safety, and service life of the products.

[0003] The winding test is a classic method for evaluating the plastic deformation capacity of metal wires. Its principle is simple, operation is convenient, and results are intuitive, playing a vital role in the production, quality inspection, and application of metal wires. This test is often categorized as a process test for raw materials, and metal wire manufacturers have a wide demand for it.

[0004] The basic principle of the wire winding test is to clamp one end of the wire and then tightly wind it around a rotating mandrel. The torsion testing machine is a common testing machine used for testing the torsional properties of materials. Its structure generally includes an active end that rotates around an axis and a fixed end that is fixed in position along the axial direction, with both ends holding the sample to be tested using chucks. This structure of the torsion testing machine was not specifically designed for wire winding tests, therefore it cannot be directly applied to winding tests.

[0005] Therefore, the inventors have provided a clamp for testing metal wire winding. Utility Model Content

[0007] (2) Technical solution This utility model provides a clamp for a metal wire winding test, including a clamping part, a disc part, a mandrel, and a supporting part. The two opposite end faces of the disc part are respectively connected to the first end of the clamping part and the first end of the mandrel. The second end of the clamping part is used to connect to the driving end of a torsion testing machine and rotate synchronously under the drive of the torsion testing machine. The second end of the mandrel is connected to the supporting part. The supporting part is used to connect to the fixed end of the torsion testing machine. The mandrel is used to wind metal wire.

[0008] Furthermore, the clamping part and the disc part are integrally formed.

[0009] Furthermore, the fixture for the metal wire winding test also includes a base, through which the mandrel is mounted on the disc portion.

[0010] Furthermore, the core rod and the base are connected by a transitional arc.

[0011] Furthermore, a blind hole is provided at the center of one end of the disc facing the mandrel, and the base is installed in the blind hole.

[0012] Furthermore, the clamp for the metal wire winding test also includes fasteners. The disc portion has a first through hole in its radial direction, and the base has a second through hole in its radial direction. The diameters of the first through hole and the second through hole are the same. When the base is installed in the blind hole, the first through hole and the second through hole are connected. The fasteners are sequentially inserted through the first through hole and the second through hole to securely connect the disc portion and the base.

[0013] Furthermore, the disc portion has a third through hole along its thickness direction for assisting in limiting and clamping the fixed end of the metal wire.

[0014] Furthermore, the support portion has a mounting hole at one end facing the mandrel, and the second end of the mandrel is placed in the mounting hole, wherein the diameter of the mandrel is smaller than the diameter of the mounting hole.

[0015] Furthermore, the mounting hole is a through hole, and the second end of the mandrel passes through the mounting hole and extends out of the other end of the support portion.

[0016] Furthermore, the clamping part is hexagonal prism-shaped.

[0017] (3) Beneficial effects In summary, this invention achieves the rotation of the mandrel by connecting the clamping part and the supporting part, which are respectively connected to the driving end and the fixed end of the torsion testing machine, thereby completing the winding of the metal wire.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] This utility model embodiment provides a clamp for a metal wire winding test. See [link to relevant documentation]. Figure 1 The fixture may include a clamping part 1, a disc part 2, a mandrel 3 and a support part 4. The two opposite end faces of the disc part 2 are respectively connected to the first end of the clamping part 1 and the first end of the mandrel 3. The second end of the clamping part 1 is used to connect to the drive end of the torsion testing machine and rotate synchronously under the drive of the torsion testing machine. The second end of the mandrel 3 is connected to the support part 4. The support part 4 is used to connect to the fixed end of the torsion testing machine. The mandrel 3 is used to wind the metal wire 100.

[0026] In the above embodiment, the clamping part 1 is clamped on the three-jaw chuck of the drive end of the torsion testing machine and rotates with the rotation of the drive end of the torsion testing machine, providing torque for the torsion test process. The mandrel 3 can be installed on the disc part 2, and the metal wire 100 can be tightly wound on it during the test. Different diameter mandrels 3 can be designed for different test requirements. The support part 4 is installed on the fixed end of the torsion testing machine and is fixed and does not rotate during the test. It is used to support the mandrel 3 to form a structure similar to a simply supported beam, while not hindering the rotation of the mandrel 3.

[0027] Furthermore, such as Figure 1 As shown, the clamping part 1 is hexagonal prism. The clamping part 1 adopts a hexagonal prism design with a regular hexagonal cross-section to adapt to the torsion testing machine. The integrated molding of the clamping part 1 and the disc part 2 makes the machining process more convenient and the overall stability is stronger. Both the disc part 2 and the support part 4 are cylindrical to facilitate machining.

[0028] As an optional implementation method, such as Figures 4-5 As shown, the fixture for the metal wire winding test also includes a base 5. The mandrel 3 is mounted on the disc portion 2 via the base 5. The mandrel 3 and the base 5 are integrally formed, and the mandrel 3 and the base 5 are connected by a transition arc to reduce stress concentration at the root of the mandrel 3. Furthermore, as... Figure 2 As shown, a blind hole 201 is provided at the center of the end of the disc portion 2 facing the core rod 3, and the base 5 is installed in the blind hole 201. The blind hole 201 facilitates the installation between the base 5 and the disc portion 2, and the depth of the blind hole 201 is the same as the thickness of the base 5.

[0029] As an optional implementation, the fixture for the wire winding test also includes fasteners (not shown in the figure), which can be pins with a fixing mechanism (such as perforated pins, threaded pins at both ends, etc.). Figure 3 As shown, the disc portion 2 has a first through hole 202 along its radial direction, such as... Figure 5 As shown, the base 5 has a second through hole 501 along its radial direction. The diameter of the first through hole 202 and the second through hole 501 are the same. When the base 5 is installed in the blind hole 201, the first through hole 202 and the second through hole 501 are connected. Fasteners are sequentially inserted through the first through hole 202 and the second through hole 501 to fasten the disc part 2 and the base 5.

[0030] As an optional implementation method, such as Figure 2 As shown, the disc portion 2 has a third through hole 203 along its thickness direction for assisting in limiting and clamping the fixed end of the metal wire 100. Specifically, as... Figure 1 As shown, before starting the winding test, one end of the metal wire 100 can be bent and inserted into the third through hole 203. At this time, one end of the metal wire 100 is fixed and limited in the third through hole 203 to help the metal wire 100 to be smoothly wound on the mandrel 3 in the initial stage of winding.

[0031] As an optional implementation method, such as Figure 6 As shown, the support part 4 has a mounting hole 401 at one end facing the mandrel 3, and the second end of the mandrel 3 is placed in the mounting hole 401. The diameter of the mandrel 3 is smaller than the diameter of the mounting hole 401. Furthermore, as... Figure 7 As shown, the mounting hole 401 is a through hole, and the second end of the mandrel 3 passes through the mounting hole 401 and extends out of the other end of the support part 4. The through hole allows the mandrel 3 to extend out of the support part 4 to adjust the mandrel 3.

[0032] It should be clarified that the various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. This utility model is not limited to the specific steps and structures described above and shown in the figures. Furthermore, for the sake of brevity, detailed descriptions of known methods and techniques are omitted here.

[0033] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art without departing from the scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
