[0030] like Figure 1-2 As shown, the utility model provides a device for detecting the strength and toughness of a metal wire, comprising a base 1, a test frame 3, a mounting plate 5, a test fixing assembly 6, a pressure plate auxiliary tool 7 and a load sensor 8;

[0031] The base 1 is provided with a test button 2, and one side of the base 1 is provided with a display screen 9 and an operation interface 10;

[0032] The test stand 3 is vertically mounted on the base 1 and is provided with a sliding slot 4;

[0033] There are two mounting plates 5, and the two mounting plates 5 are slidably mounted on the test frame 3 respectively;

[0034] The two groups of test fixing assemblies 6 are symmetrically mounted on the mounting plate 5. Both groups of test fixing assemblies 6 are located between the two mounting plates 5. A buckle 11 is fixedly mounted on one side of the two mounting plates 5 close to each other. The test fixing assembly 6 includes an outer jacket 12, an inner jacket 13 and an extrusion sleeve 14. The outer jacket 12 is detachably mounted on the mounting plate 5. The outer jacket 12 is provided with an internal thread. The extrusion sleeve 14 is threadedly mounted in the outer jacket 12. The inner jacket 13 is arranged in the extrusion sleeve 14. The two ends of the inner jacket 13 resist the extrusion sleeve 14 and the outer jacket 12 respectively. Both ends of the inner jacket 13 are inclined.

[0035] The pressure plate auxiliary tool 7 is installed on the base 1;

[0036] The load sensor 8 is mounted on the mounting plate 5 close to one side of the base 1;

[0037] In this embodiment, the inner jacket 13 is made of an elastic material, and a socket 15 for rotation is provided on the extrusion jacket 14. The extrusion jacket 14 is rotated and tightened by a tool such as a wrench. When the extrusion jacket 14 rotates in a direction close to the corresponding mounting plate 5, the extrusion jacket 14 squeezes one end of the inner jacket 13, and the inner jacket 13 rotates in a direction close to the corresponding mounting plate 5, and then the other end of the inner jacket 13 is resisted by the fixed outer jacket 12, so that the inner jacket 13 can hold the center wire tightly. Furthermore, a groove is provided in the middle position of the outer periphery of the inner jacket 13.

[0038] In this embodiment, the test fixing assembly 6 has multiple groups, and the clamping ranges of the multiple groups of the test fixing assembly 6 are different. The diameter range of the metal wire that can be clamped by the test fixing assembly 6 is limited. By replacing the test fixing assembly 6 of different specifications, the diameter range of the metal wire that can be detected is expanded.

[0039] Here’s how it works:

[0040] The operator ties the two ends of the wire to the buckles 11 of the two mounting plates 5 in turn. The two ends of the wire are respectively located in the two test fixing components 6. The extrusion sleeve 14 is tightened by a wrench to rotate the extrusion sleeve 14 toward the corresponding mounting plate 5. The extrusion sleeve 14 squeezes one end of the inner jacket 13, and the inner jacket 13 rotates toward the corresponding mounting plate 5. Then, the other end of the inner jacket 13 is resisted by the fixed outer jacket 12, thereby realizing the inner jacket 13 holding the center wire tightly, solving the problem that the universal tensile testing machine cannot flexibly test different To solve the problem of firmly fixing metal wires of the same thickness, the detection device is started by the test button 2, and the two mounting plates 5 respectively drive the two sets of test fixing components 6 to run in opposite directions. In the process of increasing tension, the elastic force sensitive element in the load sensor 8 is deformed under the action of the force, and the force exerted on the metal wire is converted into an electrical signal through the load sensor 8. The electrical signal is amplified and converted into a digital signal through the measurement conversion circuit, and finally displayed on the display screen 9. When the metal wire is broken, the detection is stopped, and the test results of the strength and toughness of the metal wire are obtained.

[0041] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
