Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of testing, more particularly, it relates to a strength testing device for alloy wire. BACKGROUND

[0002] The strength testing of alloy wire is a comprehensive system for evaluating its mechanical properties, and the tensile testing is a commonly used method, which simulates the stress state under axial tensile load to obtain the strength, plasticity and fracture characteristics of the alloy wire, thereby providing key data support for material selection, production process verification, product quality control and failure analysis.

[0003] At present, the testing process of the tensile strength of alloy wire is as follows: the staff first winds the two ends of the alloy wire on two cylindrical shafts with annular grooves; then separates the two cylindrical shafts in opposite directions to apply axial tensile force to the alloy wire; during the testing process, the tensile sensor monitors the tensile strength of the alloy wire in real time until the alloy wire breaks, thereby completing the testing of the ultimate tensile properties.

[0004] However, the manual winding of the alloy wire cannot guarantee the consistency of the length of the two ends, that is, the length of the manually wound alloy wire cannot be guaranteed, so that during the testing process, the lengths of the two ends will change unequally, and then the single-sided stress concentration occurs, at this time, the fracture position of the alloy wire deviates, resulting in that the fracture occurs at one end in advance, rather than at the effective test section position, thereby affecting the final strength test result.

[0038] Please refer to Figures 2-4 The specific structure of the test assembly 3 is as follows: The testing assembly 3 comprises a moving mechanism 31, an upper testing mechanism 32 mounted on the top of one side of the moving mechanism 31, and a lower testing mechanism 33 sliding on the side wall of the moving mechanism 31, one side of the upper testing mechanism 32 is rotatably provided with an upper winding mechanism 34, one side of the lower testing mechanism 33 is rotatably provided with a lower winding mechanism 35, the alloy wire is wound on the upper winding mechanism 34 and the lower winding mechanism 35, then the lower winding mechanism 35 is driven to move downward by the moving mechanism 31, so that the alloy wire is pulled, and the lower testing mechanism 33 tests the pulling force of the alloy wire during the pulling process until the alloy wire is pulled off, thereby testing the pulling strength of the alloy wire.

[0039] Referring to Figure 3 , the specific structure of the moving mechanism 31 is as follows: The moving mechanism 31 comprises an electric sliding rail mechanism 311 mounted on the top of the workbench 1 and two through grooves 312 opened on one side of the electric sliding rail mechanism 311, a measuring scale 313 is mounted on one side of the electric sliding rail mechanism 311 between the two through grooves 312, the lower testing mechanism 33 penetrates through the two through grooves 312 and is slidingly connected with the electric sliding rail mechanism 311, the electric sliding rail mechanism 311 is composed of a housing and an electric sliding rail, the electric sliding rail is vertically mounted in the housing, the through grooves 312 are opened on the side wall of the housing, the electric sliding rail can be a stepper motor linear sliding rail seat module, which is not specifically limited here, the lower testing mechanism 33 is connected with the sliding seat of the electric sliding rail, when the electric sliding rail is started, the lower testing mechanism 33 is driven to move downward by the sliding seat, thereby the lower winding mechanism 35 moves downward, the lower winding mechanism 35 and the upper winding mechanism 34 are separated, thereby the pulling strength test of the alloy wire is performed.

[0040] Referring to Figure 3 , Figure 4 and Figure 8 , the upper testing mechanism 32 comprises a multi-stage telescopic cylinder 323 screw-connected to the inside of one side of the electric sliding rail mechanism 311, the piston rod of the multi-stage telescopic cylinder 323 penetrates through the top of the electric sliding rail mechanism 311 vertically downward and is provided with a pulling force sensor 321, the bottom of the pulling force sensor 321 is connected with a first mounting seat 322, the upper winding mechanism 34 is rotatably connected to one side of the first mounting seat 322, the multi-stage telescopic cylinder 323 is used for adjusting the height of the pulling force sensor 321 and the upper winding mechanism 34, and the pulling force sensor 321 is in a suspended state, and the first mounting seat 322 is used for connecting the pulling force sensor 321 and the upper winding mechanism 34.

[0041] Referring to Figure 6The lower test mechanism 33 comprises a sliding table 331, one side of the sliding table 331 penetrating through the two through grooves 312 and being in sliding connection with the electric sliding rail mechanism 311, and the side of the sliding table 331 away from the electric sliding rail mechanism 311 is provided with a second mounting seat 332. The lower winding mechanism 35 is rotationally connected to one side of the second mounting seat 332. The sliding table 331 is connected with the sliding seat sliding on the electric sliding rail. When the sliding table 331 moves with the sliding seat, the sliding table 331 is guided through the two through grooves 312. The second mounting seat 332 is used for mounting and positioning the lower winding mechanism 35. During the movement of the sliding table 331, the distance between the lower winding mechanism 35 and the upper winding mechanism 34 changes. When they are separated from each other, the alloy wire is pulled, and the top end of the alloy wire exerts a downward pulling force on the upper winding mechanism 34. The upper winding mechanism 34 pulls the tension sensor 321 downward. The alloy wire between the lower winding mechanism 35 and the upper winding mechanism 34 is an effective test section. At this time, the tension sensor 321 tests the tensile strength of the alloy wire, until the alloy wire is broken.

[0042] When the alloy wire test is completed, the staff removes the alloy wire and replaces it with a new alloy wire. The two ends of the new alloy wire to be tested are wound on the outer wall of the upper winding mechanism 34 and the lower winding mechanism 35 respectively. Then the distance between the upper winding mechanism 34 and the lower winding mechanism 35 is adjusted, so as to test the tensile strength of the alloy wire again by using the tension sensor 321.

[0043] In the embodiment two, the length of the manually wound alloy wire cannot be guaranteed, so that the lengths of the two ends wound in the test process will change by different amounts, and then unbalanced stress concentration occurs. At this time, the breaking position of the alloy wire deviates, so that the breaking occurs in one end in advance, rather than in the effective test section, thereby affecting the final strength test result.

[0044] Therefore, the upper winding mechanism 34 and the lower winding mechanism 35 are further improved.

[0045] Referring to Figures 4-7 The upper winding mechanism 34 comprises an upper electric rotating column 341 rotationally connected to one side of the upper test mechanism 32. An upper winding groove 342 is formed in the outer side wall of the upper electric rotating column 341. An upper wire placing groove 343 is formed in the end of the upper electric rotating column 341. The upper wire placing groove 343 is in communication with the upper winding groove 342. An upper support 344 is mounted on the end of the upper electric rotating column 341. An upper wire column 345 is rotationally connected to the side wall of the upper support 344. The upper wire column 345 penetrates through the upper support 344 and extends into the inside of the upper wire placing groove 343 and is rotationally connected with an upper pressing plate 346. The upper pressing plate 346 is located in the inside of the upper wire placing groove 343.

[0046] When the worker winds the alloy wire on the upper winding mechanism 34, first, the worker sets the end of the alloy wire inside the upper wire slot 343, then rotates by rotating the upper wire column 345, and then uses the upper pressing plate 346 to press the alloy wire inside the upper wire slot 343, and then winds the alloy wire upward inside the upper winding slot 342, and the winding length is half a circle, and then the alloy wire extends vertically downward to the lower winding mechanism 35 for winding.

[0047] Referring to Figures 4-7 The lower winding mechanism 35 comprises a lower electric rotating column 351 rotating on one side of the lower testing mechanism 33, the outer side wall of the lower electric rotating column 351 is provided with a lower winding slot 352, the end of the lower electric rotating column 351 is provided with a lower wire slot 353, the lower wire slot 353 is in communication with the lower winding slot 352, the end of the lower electric rotating column 351 is provided with a lower support 354, the side wall of the lower support 354 is rotatably connected with a lower wire column 355, the inside of the lower wire slot 353 is provided with a lower pressing plate 356, and the lower wire column 355 penetrates through the lower support 354 and is rotatably connected with the lower pressing plate 356.

[0048] After the alloy wire is fixed from the upper winding mechanism 34, the worker sets the bottom end of the alloy wire inside the lower wire slot 353, then rotates by rotating the lower wire column 355, and then uses the lower pressing plate 356 to press the alloy wire inside the lower wire slot 353, and then winds the alloy wire upward inside the lower winding slot 352, and the winding length is half a circle, at this time, the two ends of the alloy wire are fixed on the upper winding mechanism 34 and the lower winding mechanism 35 respectively.

[0049] In this embodiment, after the alloy wire is fixed, the upper electric rotating column 341 and the lower electric rotating column 351 are rotated, and the lower winding mechanism 35 is moved upward to cooperate, and then the automatic winding of the alloy wire is realized, and the winding of the upper electric rotating column 341 and the lower electric rotating column 351 is performed in sequence, that is, the upper electric rotating column 341 is wound first, at this time, the lower winding mechanism 35 is moved upward to cooperate, until the winding of the alloy wire on the upper electric rotating column 341 is completed, then the upper electric rotating column 341 stops rotating, the lower winding mechanism 35 is moved upward again and rotates synchronously to wind, until the winding of the alloy wire on the lower electric rotating column 351 is completed, by controlling the rotation angle of the upper electric rotating column 341 and the lower electric rotating column 351, the length of the alloy wire wound is consistent, and manual operation is replaced, reducing the situation of hand injury of the worker, and after winding is completed, the alloy wire tensile strength test is performed.

[0050] In the single-side winding process of the upper electric rotating column 341 or the lower electric rotating column 351, tension imbalance may occur, i.e. in the mechanical winding process, the lower winding mechanism 35 needs to be controlled to move and wind in linkage, if the alloy wire itself is bent, the tension of the alloy wire is relatively complex, which causes the instantaneous effective length of the alloy wire to change unevenly in the winding process, and further causes the tension to be large and small.

[0051] Referring to Figure 9 and Figure 10 Therefore, the wire guide assembly 4 is installed on one side of the test assembly 3, which is used to assist in guiding the alloy wire. The ends of the alloy wire cannot overlap each other during the winding process on the outer wall of the upper electric rotating column 341 or the lower electric rotating column 351. The overlapping steel wire sections are pressed against each other, which not only forms a local stress far exceeding the normal tension at the contact point, but also may cause the steel wire to break prematurely. Although manual operation can achieve the purpose of winding, the tension cannot be controlled, and there is a situation of single-side stress concentration.

[0052] Referring to Figure 9 and Figure 10 Therefore, the wire guide assembly 4 includes a fixed plate 41 connected to one side of the moving mechanism 31. One side of the fixed plate 41 is threadedly connected with a lead screw 43. One end of the lead screw 43 is rotatably connected with a U-shaped plate 44. The other end of the U-shaped plate 44 penetrates through the lead screw 43. Two guide rods 42 are symmetrically connected to the side of the U-shaped plate 44 close to the fixed plate 41. Both of the two guide rods 42 penetrate through the lead screw 43.

[0053] When the two ends of the alloy wire are fixed on the upper electric rotating column 341 or the lower electric rotating column 351 and have not been wound yet, the staff adjusts the position of the U-shaped plate 44 by rotating the lead screw 43, and the U-shaped plate 44 is attached to the outer wall end position of the upper electric rotating column 341 and the lower electric rotating column 351.

[0054] Referring to Figure 9 and Figure 10The inside of the U-shaped plate 44 is provided with a wire guide groove 45, one side of the wire guide groove 45 is symmetrically connected with two auxiliary rods 47, the two auxiliary rods 47 are both arranged through the inner side wall of the wire guide groove 45, one side of the U-shaped plate 44 is horizontally provided with a gas cylinder 46, the piston rod end of the gas cylinder 46 extends to the inside of the U-shaped plate 44 and is connected with the wire guide groove 45, the opening position of the wire guide groove 45 is symmetrically connected with two protrusions 48, one side of the two protrusions 48 is both provided with an arc-shaped part, after the two ends of the alloy wire are respectively fixed on the upper electric rotating column 341 or the lower electric rotating column 351, the effective test section of the alloy wire between the upper electric rotating column 341 and the lower electric rotating column 351 enters the inside of the wire guide groove 45, then the upper electric rotating column 341 is driven to move downward by the multi-stage telescopic cylinder 323, the alloy wire is wound, the lower electric rotating column 351 is driven to move upward by the electric sliding rail mechanism 311, at the same time, the upper electric rotating column 341 and the lower electric rotating column 351 are close to each other and rotate at the same time, and the rotating directions are opposite, without rotating in sequence, in this process, the piston rod of the gas cylinder 46 is retracted and moves the wire guide groove 45, the wire guide groove 45 transversely pulls the effective test section of the alloy wire, in this state, the alloy wire is guided and gradually spirally wound on the outer wall of the upper electric rotating column 341 and the lower electric rotating column 351, and when the wire guide groove 45 guides the effective test section of the alloy wire, the alloy wire is transversely pulled and is in a tension state, thereby ensuring that the alloy wire wound on the upper electric rotating column 341 or the lower electric rotating column 351 has the same tension degree.

[0055] After the winding is completed, the upper electric rotating column 341 moves upward, at this time the alloy wire is tensioned in the vertical direction, after the tensioning is completed, the staff can record the positions of the upper electric rotating column 341 and the lower electric rotating column 351 on the measuring scale 313, then the lower electric rotating column 351 starts to move downward to pull the alloy wire, in the pulling process, the alloy wire is gradually deformed, and at the same time the tension sensor 321 records the test data, until the alloy wire is pulled off.

[0056] By arranging the two protrusions 48 at the opening of the wire guide groove 45 and the arc-shaped parts on one side of the protrusions 48, when the alloy wire enters the wire guide groove 45, the alloy wire is limited and guided by the protrusions 48, which ensures that the alloy wire stably enters the inside of the wire guide groove 45, and achieves the effects of assisting the alloy wire to accurately enter the wire guide groove 45, reducing the wear of the alloy wire in the wire guiding process, and ensuring smooth winding and guiding.

[0057] When the alloy wire is broken in the effective test section, since the alloy wire is broken in a lengthened and tightened state, the alloy wire will be broken on the outer wall of the upper electric rotating column 341 and the lower electric rotating column 351, after the alloy wire is broken, the winding state of the alloy wire will be disordered, and then the alloy wire is not convenient to take off.

[0058] To this end, the first pressing plate 324 is installed on one side of the first mounting seat 322 and above the upper winding mechanism 34, and the second pressing plate 333 is installed on one side of the second mounting seat 332 and below the lower winding mechanism 35. By setting the first pressing plate 324 and the second pressing plate 333, when the alloy wire breaks on the outer wall of the upper electric rotating column 341, the first pressing plate 324 limits the range of the broken alloy wire, thereby reducing the disorder of the broken alloy wire.

[0059] Specifically, when the alloy wire breaks on the outer wall of the lower electric rotating column 351, the second pressing plate 333 also limits the breaking range, so that the broken alloy wire is constrained in a certain area, avoiding excessive scattering of the broken alloy wire, which leads to winding disorder. After the test is completed, the staff can more conveniently and quickly clean and remove the broken alloy wire, reduce the cleaning time, improve the efficiency of the entire test process, and at the same time, the setting of the first pressing plate 324 and the second pressing plate 333 can also protect the upper winding mechanism 34 and the lower winding mechanism 35 to a certain extent, preventing the broken alloy wire from causing accidental damage to the equipment.

[0060] Obviously, the above-described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.
