Description

A tungsten wire diamond wire busbar strength testing device Technical Field

[0001] This utility model relates to the field of metal material testing technology, and in particular to a tungsten wire diamond wire busbar strength testing device. Background Technology

[0002] Tungsten wire diamond wire busbar is a composite wire made of tungsten wire as the base material and diamond particles are attached to the surface through electroplating or deposition processes. It is used for cutting hard and brittle materials such as photovoltaic silicon wafers and sapphire, and has both high strength and cutting wear resistance.

[0003] In precision machining applications involving hard and brittle materials such as photovoltaic silicon wafer cutting and sapphire processing, tungsten wire diamond wire busbars require strength testing to ensure cutting efficiency, yield, and operational safety. Tungsten wire diamond wire busbar strength testing equipment can fix both ends of the busbar with a high-precision clamping mechanism and apply a uniform axial tensile load to measure mechanical parameters such as tensile strength, yield strength, and elongation at break. This allows for the assessment of material process reliability, optimization of cutting parameters, and prevention of wire breakage risks.

[0004] However, existing tungsten wire diamond wire busbar strength testing equipment has the following shortcomings:

[0005] In the existing technology, the tungsten wire diamond wire busbar strength testing equipment needs to clamp and fix both ends of the busbar. However, the existing equipment usually only performs a single clamping. In the ultimate load test of the high stiffness tungsten wire, the single clamping structure may slip between the busbar and the clamp or the tungsten wire may fall out of the clamp due to insufficient clamping force or limited friction coefficient of the contact surface. As a result, the test cannot reach the true fracture load of the material, and the data deviation rate increases significantly.

[0006] Therefore, we propose a tungsten wire diamond wire busbar strength testing device to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a tungsten wire diamond wire busbar strength testing device, which uses a threaded drive to clamp one end of the tungsten wire diamond wire busbar between a fixed seat and a fastening threaded seat, and at the same time uses a cylinder to drive a trapezoidal clamping assembly to generate multi-point wedge extrusion, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a tungsten wire diamond wire busbar strength testing device, comprising a base, a protective box fixedly connected to the top of the base, two first guide rods fixedly connected to the inner wall of the protective box, a first movable plate movably sleeved between the outer walls of the two first guide rods, mounting brackets fixedly connected to the bottom of the inner wall of the protective box and the bottom of the first movable plate, first clamping blocks fixedly connected to the inner walls of the two mounting brackets, cylinders fixedly connected to the inner walls of the two mounting brackets, second clamping blocks fixedly connected to the telescopic ends of the two cylinders, positioning plates fixedly connected to the inner walls of the two mounting brackets, fixed seats fixedly connected to the top of the inner walls of the two mounting brackets, threaded rods fixedly connected to the bottom of the two fixed seats, and fastening threaded seats threadedly connected to the outer walls of the two threaded rods.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in Figures 1-4, provides a technical solution: a tungsten wire diamond wire busbar strength testing device, including a base 1, a protective box 2 fixedly connected to the top of the base 1, two first guide rods 3 fixedly connected to the inner wall of the protective box 2, a first moving plate 4 movably sleeved between the outer walls of the two first guide rods 3, mounting brackets 5 fixedly connected to the bottom of the inner wall of the protective box 2 and the bottom of the first moving plate 4, first clamping blocks 6 fixedly connected to the inner walls of the two mounting brackets 5, cylinders 7 fixedly connected to the inner walls of the two mounting brackets 5, second clamping blocks 8 fixedly connected to the telescopic ends of the two cylinders 7, positioning plates 9 fixedly connected to the inner walls of the two mounting brackets 5, fixed seats 10 fixedly connected to the top of the inner walls of the two mounting brackets 5, threaded rods 11 fixedly connected to the bottom of the two fixed seats 10, and fastening threaded seats 12 threadedly connected to the outer walls of the two threaded rods 11.

[0026] The effect achieved by the entire embodiment 1 is as follows: When fixing the tungsten wire diamond wire busbar, the busbar is first passed through the first clamping block 6 and the second clamping block 8, so that it passes through the positioning plate 9, and one end is wrapped around the threaded rod 11. Then, the fastening threaded seat 12 is rotated to clamp the busbar between the fixed seat 10 and the fastening threaded seat 12. By activating the cylinder 7, its extension end drives the second clamping block 8 to move towards the first clamping block 6. Utilizing the trapezoidal structure of the first clamping block 6 and the second clamping block 8, the busbar and the clamping block assembly form a multi-point wedge clamp, ensuring stable positioning and no relative slippage during clamping. This dual clamping method can maintain the clamping reliability of the busbar in the ultimate load test, avoid slippage and fall off, and ensure the detection accuracy and effectiveness of the detection process.

[0027] Example 2, as shown in Figures 2-4, has a fixed rod 13 fixedly connected to the top of the first movable plate 4, four second guide rods 14 fixedly connected to the top of the base 1, a top plate 15 fixedly connected between the tops of the four second guide rods 14, a hydraulic cylinder 16 fixedly connected to the top of the top plate 15, and the telescopic end of the hydraulic cylinder 16 movably penetrating inside the top plate 15. A second movable plate 17 is movably sleeved between the outer walls of the four second guide rods 14, and the telescopic end of the hydraulic cylinder 16 is fixedly connected to the top of the second movable plate 17. Hanging rings 18 are fixedly connected to both the fixed rod 13 and the outer wall of the second movable plate 17. A tension gauge 19 movably contacts the outer walls of two hanging rings 18. A hinge is fixedly connected to one side of the outer wall of the protective box 2. A protective door 20 has an observation window 21 on its inner wall. A handle 22 is fixedly connected to one side of the outer wall of the protective door 20. A limit groove 23 is opened on one side of the outer wall of the protective door 20. A fixing frame 24 is fixedly connected to one side of the outer wall of the protective box 2. Two mounting grooves 25 are opened on the outer wall of the fixing frame 24. Springs 26 are fixedly connected to the inner walls of the two mounting grooves 25. A pull plate 27 is fixedly connected between the outer walls of the two springs 26. Two connecting rods 28 are fixedly connected to one side of the outer wall of the pull plate 27. The outer walls of the two connecting rods 28 are movably inserted into the inside of the fixing frame 24. A limit block 29 is fixedly connected between the outer walls of the two connecting rods 28. The outer wall of the limit block 29 is movably inserted into the inside of the limit groove 23.

[0028] The effect achieved by the entire embodiment 2 is as follows: During the testing process, after the tungsten wire diamond wire busbar is fixed, the pull plate 27 is pulled first, which moves the limiting block 29 to one side. At the same time, the two springs 26 are stretched to generate elastic deformation potential energy. After the protective door 20 is closed, the limiting groove 23 corresponds to the position of the limiting block 29. The elastic restoring force of the two springs 26 is used to make the limiting block 29 snap into the limiting groove 23, thus completing the fixing of the protective door 20. Through the cooperation between the protective box 2 and the protective door 20, the safety during testing can be ensured, avoiding the risk of splashing caused by the breakage of the tungsten wire diamond wire busbar during testing, and ensuring the safety of operators and the normal operation of equipment.

[0029] The working principle of the entire device is as follows: First, the two ends of the tungsten wire diamond wire busbar are fixed. The operator then passes the busbar sequentially through the first clamping block 6, the second clamping block 8, and the positioning plate 9, with one end wound around the threaded rod 11. Next, the fastening threaded seat 12 is rotated, and the busbar is clamped between the fixed seat 10 and the fastening threaded seat 12 using the threaded engagement between the threaded rod 11 and the fastening threaded seat 12. Then, the cylinder 7 is activated, and its extension end moves the second clamping block 8 towards the first clamping block 6. The trapezoidal structure of the first and second clamping blocks forms a multi-point wedge clamping effect between the busbar and the clamping components, ensuring the busbar is stable and without displacement during clamping. This double-clamping design enhances the reliability of the fixation. After the busbar is fixed, the operator pulls the pull plate 27 to move the limit block 2. 9. The lateral movement of the pull plate 27 stretches the two springs 26, causing them to elastically deform. At this time, the protective door 20 is closed. After the position of the limiting groove 23 corresponds with that of the limiting block 29, the limiting block 29 is locked into the limiting groove 23 by relying on the elastic restoring force of the spring 26, thus locking the protective door 20. The protective box 2 and the protective door 20 form a closed protective structure to ensure the safety of the testing process, effectively blocking the splashes generated when the busbar breaks, and protecting the safety of the operators and equipment. Finally, the hydraulic cylinder 16 is activated, and its telescopic end drives the second moving plate 17 and the first moving plate 4 to move upward synchronously, applying an axial tensile load to the tungsten wire diamond wire busbar. The tensile force value is monitored in real time by the tension gauge 19 to provide data support for strength testing.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
