Description

Technical Field

[0001] This utility model belongs to the field of metal wire testing technology, and specifically relates to a metal wire compressive strength testing device. Background Technology

[0002] Metal wire refers to a slender metal product of a certain length made from metal or metal alloy as raw material through processes such as drawing and rolling. In most application scenarios, metal wire needs to withstand a certain pressure or indirect pressure. If the compressive strength is insufficient, it is easy to deform or break, causing safety hazards or equipment failure. Therefore, a compressive strength testing device is needed.

[0003] Current metal wire compressive strength testing devices have significant limitations in their testing range. The relative positions of the pressure application mechanism and the wire fixing mechanism are mostly fixed, allowing for compressive strength testing only at a single preset position on the metal wire, such as the middle. When actual testing requires multiple positions on the wire, the operator must first pause the testing process, manually loosen the wire fixing mechanism from the metal wire, and manually push or adjust the wire's position within the fixing mechanism. The operation is very cumbersome and requires repeated starting and stopping of the equipment. Utility Model Content

[0018] Example

[0019] refer to Figures 1 to 4 The compressive strength testing device for metal wire described in this embodiment includes a base plate 1. A power assembly 4 is provided on one side of the base plate 1. A moving block 2 is slidably connected to the base plate 1 via the power assembly 4. A mounting frame 3 is fixedly connected to one side of the moving block 2. A positioning assembly 5 is provided on one side of the mounting frame 3. A frame 10 is fixedly connected to one side of the top of the base plate 1. A cylinder 6 is fixedly connected to the top of the frame 10. An assembly plate 7 is fixedly connected to the output end of the cylinder 6. A stamping rod 8 is fixedly connected to the bottom end of the assembly plate 7. A pressure sensor 9 is provided in the middle of the stamping rod 8.

[0020] refer to Figure 3-4The power assembly 4 includes a first motor 41, which is fixedly connected to one side of the base plate 1. A first driving gear 42 is fixedly connected to the output end of the first motor 41. A first driven gear 43 is meshed with one side of the first driving gear 42. A lead screw 44 is fixedly connected to one side of the first driven gear 43. The moving block 2 is threadedly connected to the lead screw 44. A sliding groove 45 is provided inside the base plate 1. The lead screw 44 is rotatably connected inside the sliding groove 45. One side of the moving block 2 is slidably connected to the sliding groove 45. Limiting grooves 46 are provided on both sides of the sliding groove 45. Limiting blocks 47 are slidably connected inside the limiting grooves 46. One side of the limiting block 47 is fixedly connected to one side of the moving block 2. By setting the power assembly 4, when it is necessary to adjust the wire position to test different areas, the first motor 41 is started. The output end 41 drives the first driving gear 42 to rotate, and the first driving gear 42 drives the first driven gear 43 to rotate, so that the first driven gear 43 drives the lead screw 44 to rotate in the slide groove 45 of the base plate 1. Since the moving block 2 is threadedly connected to the lead screw 44 and one side of the moving block 2 is slidably engaged with the slide groove 45, when the lead screw 44 rotates, it drives the moving block 2 to slide along the slide groove 45. At the same time, the limiting blocks 47 on both sides of the moving block 2 slide synchronously in the limiting grooves 46 inside the slide groove 45, limiting the sliding direction of the moving block 2 and preventing the moving block 2 from deviating. During the sliding process of the moving block 2, it drives the mounting bracket 3 and the positioning component 5 at the top to move synchronously until the position of the wire to be tested is aligned with the stamping rod 8. There is no need to manually loosen the wire, manually adjust the position and then re-clamp it. The position adjustment can be completed by motor drive alone, which greatly simplifies the operation steps, reduces the number of equipment start-ups and shutdowns, and improves the efficiency of multi-position testing.

[0021] refer to Figure 2-3The positioning component 5 includes a second motor 51, which is fixedly connected to one side of the mounting frame 3. A second driving gear 52 is fixedly connected to the output end of the second motor 51. A second driven gear 53 is meshed with one side of the second driving gear 52. A shaft 54 ​​is fixedly connected to one side of the second driven gear 53. A rotating frame 55 is rotatably connected to the inner side of the mounting frame 3 via the shaft 54. Support blocks 56 are fixedly connected to both sides of the rotating frame 55. An abutment block 57 is provided inside the rotating frame 55 on the upper side of the support blocks 56. Electric push rods 58 are fixedly connected to both sides of the top end of the rotating frame 55. The output end of the electric push rod 58 is fixed to one side of the abutment block 57. Connection; By setting the positioning component 5, first place both ends of the wire on the support blocks 56 on both sides of the rotating frame 55, start the electric push rod 58, the electric push rod 58 pushes the contact block 57 to move downward until the contact block 57 is tightly attached to the surface of the wire, and the support block 56 clamps and fixes the wire. Start the second motor 51, the output end of the second motor 51 drives the second drive gear 52 to rotate, the second drive gear 52 drives the second driven gear 53 to rotate, so that the second driven gear 53 drives the shaft 54 ​​to rotate, the shaft 54 ​​drives the rotating frame 55 inside the mounting frame 3 to rotate synchronously, the rotating frame 55 drives the clamped wire to adjust the angle until the test surface of the wire is adapted to the pressure direction of the stamping rod 8, thereby expanding the applicable range of the device.

[0022] refer to Figure 1 Guide rods 11 are fixedly connected to both sides of the top of the assembly plate 7. One side of the guide rod 11 slides through the frame 10. When the cylinder 6 drives the assembly plate 7 to press the stamping rod 8 downward, the guide rod 11 slides through the frame 10, restricting the movement direction of the assembly plate 7 and preventing the assembly plate 7 from tilting due to uneven force.

[0023] Operating principle and advantages: First, place both ends of the metal wire to be tested on the support blocks 56 on both sides of the rotating frame 55. Activate the electric push rod 58 at the top of the rotating frame 55. The electric push rod 58 pushes the contact block 57 downwards until the contact block 57 is tightly against the wire surface, working in conjunction with the support blocks 56 to clamp the wire. This step eliminates the need for manual tightening of the clamps. The electric push rod 58 provides a stable and uniform clamping force, preventing uneven clamping force from causing wire deformation or slippage. If the wire needs to be adjusted for testing angle, activate the second motor 51. The second motor 51 drives the second drive gear 52 to rotate, which in turn drives the second driven gear 53 to rotate, causing the shaft 54 ​​and the rotating frame 55 to rotate, aligning the wire's test surface with the pressure direction of the stamping rod 8. Then, if different positions of the wire need to be tested, activate the first motor 41. The first motor 41 drives the first drive gear... Rotation 42 drives the first driven gear 43 to rotate, causing the lead screw 44 to rotate within the slide groove 45 of the base plate 1. This causes the moving block 2 to slide within the slide groove 45. The limiting blocks 47 on both sides of the moving block 2 slide synchronously within the limiting groove 46, ensuring stable movement without deviation. The moving block 2 drives the mounting frame 3 to move until the wire to be tested is aligned with the stamping rod 8. This eliminates the need for manual wire loosening, adjustment, and re-clamping, greatly simplifying the operation and reducing the number of equipment start-ups and shutdowns. Subsequently, the cylinder 6 at the top of the frame 10 is activated. The cylinder 6 pushes the assembly plate 7 and the stamping rod 8 downward. The guide rod 11 at the top of the assembly plate 7 slides along the frame 10, limiting the direction of movement of the assembly plate 7 and preventing the stamping rod 8 from shifting and causing local stress concentration in the wire. When the stamping rod 8 applies pressure to the wire, the pressure sensor 9 in the middle monitors the pressure value in real time until the wire exhibits a preset deformation or breaks. The data is then recorded to complete the test.
