Description

Technical Field

[0001] This utility model relates to the field of beryllium bronze belt toughness testing technology, and in particular to a toughness testing device for beryllium bronze belt. Background Technology

[0002] A toughness testing device for beryllium bronze strip typically involves multiple components, including a main structure, a support platform, a clamping mechanism, and a testing mechanism. These components work together to achieve accurate and reliable testing of the beryllium bronze strip material. The working principle of the beryllium bronze strip toughness testing device is usually based on the material's mechanical properties and testing standards. During the testing process, the device applies a certain external force to the sample, such as tensile or bending force, and measures parameters such as the sample's deformation and fracture point. By analyzing and calculating these parameters, the toughness performance index of the beryllium bronze strip can be obtained.

[0003] Existing testing equipment cannot quickly clamp copper strips; copper strip clamping takes a long time and the testing efficiency is poor.

[0004] An existing patent (publication number: CN217033421U) discloses a brass strip toughness testing device, which includes a workbench and a housing. The housing is installed in the middle of the top of the workbench, and a cooling box is installed near the bottom of one side of the housing. A control box is installed near the top of one side of the housing via a connecting rod. A tensioner is installed in the middle of the top of the housing, and an electric telescopic device B is installed in the middle of the bottom of the workbench. Both the electric telescopic device B and the output end of the tensioner are equipped with clamping seats inside the housing. Motors are installed in the middle of the rear surface of the clamping seats on both sides. By setting up clamping seats, clamping heads, and motors, it achieves the effect of rapid clamping of brass strips, improving the clamping efficiency of brass strips, and thus improving the testing efficiency of brass strips.

[0005] To address the aforementioned issues, while existing patents have proposed solutions that enable rapid clamping of copper strips by incorporating a clamping base, clamping head, and motor, these solutions lack anti-slip properties. During tensile testing of the copper strip, the clamped strip is prone to slippage, leading to deviations in the measured parameters. Summary of the Invention

[0006] The purpose of this invention is to provide a toughness testing device for beryllium bronze strips, which brings two clamping plates close to each other to clamp and fix one end of the copper strip. The anti-slip protrusions on the clamping plates can play an anti-slip role, thereby effectively reducing the slippage of the copper strip when it is pulled, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a toughness testing device for beryllium bronze strip, comprising a device base, a mounting frame fixed on the upper surface of the device base, a clamping mechanism for clamping the copper strip fixed at the upper end of the device base, and a testing mechanism for testing the copper strip installed inside the mounting frame.

[0008] The clamping mechanism includes a fixed block, a fixed clamping member fixed on the upper surface of the fixed block, a movable clamping member above the fixed clamping member, a tension sensor fixed on the upper surface of the movable clamping member, and adjusting screws installed on the side walls of both the movable clamping member and the fixed clamping member. Two clamping plates are slidably connected to the outer surface of the adjusting screws, and several anti-slip protrusions are fixed on the inner walls of the two clamping plates.

[0009] Preferably, the detection mechanism includes a dual-axis motor, which is fixed inside the mounting frame by bolts, and a transmission rod is fixed to the power output shaft of the dual-axis motor.

[0010] Preferably, the end of the transmission rod is fixed with an active helical tooth, and the side wall of the active helical tooth is engaged with a driven helical tooth.

[0011] Preferably, a lead screw is fixed to the lower surface of the driven helical tooth, and a movable block is slidably connected to the outer wall of the lead screw.

[0012] Preferably, the side wall of the movable block is fixed with a mounting plate, and the tension sensor is connected to the mounting plate by screws.

[0013] Preferably, the inner wall of the mounting bracket is provided with a limiting groove that slides and connects with the movable block.

[0014] Preferably, a fixed bearing is fitted on the outer surface of the transmission rod, and a fixing plate that is fixed to the inner wall of the mounting frame is fixed to the outer wall of the fixed bearing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The clamping mechanism brings the two clamping plates close to each other to clamp and fix one end of the copper strip. The anti-slip protrusions on the clamping plates can play an anti-slip role, thereby effectively reducing the slippage of the copper strip when it is pulled.

[0017] 2. The detection mechanism can drive the mounting plate to move upward. At this time, the copper strip is stretched. The tension sensor can detect the current stretching force. When the copper strip breaks, the data of the tensile force at the time of breakage can be recorded for subsequent calculations, and the toughness of the copper strip can be detected.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A toughness testing device for beryllium bronze strip includes a device base 1, a mounting frame 2 fixed on the upper surface of the device base 1, a clamping mechanism for clamping the copper strip fixed at the upper end of the device base 1, and a testing mechanism for testing the copper strip installed inside the mounting frame 2.

[0028] The clamping mechanism includes a fixed block 3, a fixed clamping member 31 fixed on the upper surface of the fixed block 3, a movable clamping member 32 above the fixed clamping member 31, a tension sensor 33 fixed on the upper surface of the movable clamping member 32, and adjusting screws 34 installed on the side walls of both the movable clamping member 32 and the fixed clamping member 31. Two clamping plates 35 are slidably connected to the outer surface of the adjusting screws 34, and several anti-slip protrusions 36 are fixed on the inner walls of both clamping plates 35.

[0029] By adopting the above technical solution, before using the toughness testing device for beryllium bronze strip, the device base 1 is first placed in a suitable position, and then one end of the copper strip to be tested is placed in the fixed clamping member 31 on the fixed block 3. By turning the adjusting screw 34 on the fixed clamping member 31, since the adjusting screw 34 is fixed by two screws with different thread directions, and the two clamping plates 35 are respectively threaded to the two screws with different thread directions, when the adjusting screw 34 rotates, the two clamping plates 35 move closer to each other and clamp and fix one end of the copper strip. The anti-slip protrusions 36 provided on the clamping plates 35 can play an anti-slip role, thereby effectively reducing the slippage of the copper strip when it is pulled. Then the other end of the copper strip is connected to the movable clamping member 32 in the same way.

[0030] Specifically, such as Figures 1-3 As shown, the detection mechanism includes a dual-axis motor 4, which is fixed inside the mounting frame 2 by bolts. A transmission rod 41 is fixed to the power output shaft of the dual-axis motor 4. An active helical gear 42 is fixed to the end of the transmission rod 41. A driven helical gear 43 meshes with the side wall of the active helical gear 42. A lead screw 44 is fixed to the lower surface of the driven helical gear 43. A movable block 45 is slidably connected to the outer wall of the lead screw 44. A mounting plate 5 is fixed to the side wall of the movable block 45. The tension sensor 33 is connected to the mounting plate 5 by screws. A limiting groove 6 is opened on the inner wall of the mounting frame 2, which is slidably connected to the movable block 45. A fixed bearing 8 is sleeved on the outer surface of the transmission rod 41. A fixed plate 7 is fixed to the inner wall of the mounting frame 2.

[0031] By adopting the above technical solution, the dual-axis motor 4 inside the mounting frame 2 starts, driving the two transmission rods 41 to rotate. The fixed bearing 8 set in the fixed plate 7 can play a limiting role, making the rotation of the two transmission rods 41 smoother, so that the active helical gear 42 meshes with the driven helical gear 43 to rotate, thereby driving the lead screw 44 to rotate. The limiting groove 6 opened in the mounting frame 2 plays a guiding role, so that the rotation of the lead screw 44 drives the threaded movable block 45 to move vertically, thereby driving the mounting plate 5 to move upward. At this time, the copper strip is stretched. The tension sensor 33 can detect the current stretching force. When the copper strip breaks, the data of the stretching force at the time of breakage can be recorded for subsequent calculations, and the toughness of the copper strip can be detected.

[0032] Working principle: Place one end of the copper strip to be tested into the fixing clamp 31 on the fixing block 3. By turning the adjusting screw 34 on the fixing clamp 31, since the adjusting screw 34 is made of two screws with different thread directions, and the two clamping plates 35 are respectively threaded to the two screws with different thread directions, when the adjusting screw 34 rotates, the two clamping plates 35 move closer to each other, clamping and fixing one end of the copper strip. The anti-slip protrusions 36 on the clamping plates 35 can play an anti-slip role. Connect the other end of the copper strip to the movable clamp 32 in the same way. The dual-axis motor 4 inside the mounting bracket 2 starts, driving the two transmission rods 41 to rotate. The fixed bearing 8 inside the mounting plate 7 acts as a limit, making the rotation of the two transmission rods 41 smoother. This causes the active helical gear 42 to mesh with the driven helical gear 43, which in turn drives the lead screw 44 to rotate. The limiting groove 6 inside the mounting bracket 2 acts as a guide, causing the lead screw 44 to rotate and drive the threaded movable block 45 to move vertically. This, in turn, causes the mounting plate 5 to move upward. At this time, the copper strip is stretched. The tension sensor 33 can detect the current stretching force, thus detecting the toughness of the copper strip.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
