[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a wire bending performance testing device for wire mesh processing includes a base 1, a vertical plate 2 is arranged on the top of the base 1, two sets of guide components 4 are fixedly arranged on the front side of the vertical plate 2 for clamping the wire; a turntable 3 is rotatably arranged on the front side of the vertical plate 2, and a clamping component 5 for clamping the end of the wire is arranged on the turntable 3; a driving part for driving the turntable 3 to rotate is arranged on the rear side of the vertical plate 2;

[0029] The driving part includes a driving rod 6, one end of which is rotatably arranged on the rear side of the vertical plate 2 and fixedly connected to the turntable 3, and the other end of the driving rod 6 is fixedly provided with a main gear 7; an electric telescopic rod 8 is arranged on the rear side of the vertical plate 2, and an adjusting disk 9 is rotatably arranged on the end of the movable rod of the electric telescopic rod 8, and a second motor 14 for driving the adjusting disk 9 to rotate is arranged on the electric telescopic rod 8, and at least two groups of speed gears with different gear ratios are rotatably arranged on the adjusting disk 9, and the linear speeds of the multiple groups of speed gears are consistent, and the speed gears can mesh with the main gear 7; a driving component for driving the speed gear to rotate is arranged on the adjustment plate.

[0030] In this embodiment, during the bending performance test of the metal wire, the metal wire is first passed between the two sets of guide components 4, and then the clamping component 5 is adjusted to clamp and fix the metal wire so that the part of the metal wire to be tested is between the guide component 4 and the clamping component;

[0031] Afterwards, the driving unit is started to drive the turntable 3 to reciprocate to test the bending performance of the metal wire. In order to more realistically simulate the actual use of the metal wire in an outdoor environment, a speed-changing gear mechanism is designed in the system. This mechanism can adjust the rotation speed of the turntable 3, thereby simulating the different bending degrees experienced by the metal wire under the action of natural wind.

[0032] Specifically, the driving assembly drives the speed gear to reciprocate, and then drives the electric telescopic rod 8 to drive the speed gear to move, so that a set of speed gears are engaged with the main gear 7, and the set of speed gears drives the turntable 3 to rotate through the main gear 7 and the driving rod 6;

[0033] In order to simulate the outdoor use state of the metal wire, multiple groups of speed gears with different gear ratios can be meshed with the main gear 7 in sequence; specifically, the electric telescopic rod 8 is first driven to retract to release the meshing relationship between the main gear 7 and the speed gear, and the second motor 14 is started to drive the adjustment disk 9 to rotate, so that another group of adjustment gears 10 is adjusted to a state where it can mesh with the main gear 7; then, the electric telescopic rod 8 is driven again to drive the adjustment gear 10 to mesh with the main gear 7 to drive the turntable 3; since each group of speed gears has the same linear speed but different tooth ratios, their own angular velocities are different, so the angles of driving the main gear 7 to rotate are different, and then the bending angles of driving the metal wire are different, so that the bending stresses on the metal wire are different; therefore, by using multiple groups of speed gears to mesh with the main gear 7 respectively, various bending conditions of the metal wire caused by changes in wind speed in outdoor environments can be effectively simulated, thereby comprehensively evaluating its durability and reliability in practical applications.

[0034] Preferably, the speed change gear includes an adjusting gear 10 and a gear rod 11, one end of the gear rod 11 is rotatably connected to the front side of the adjusting disk 9, and the other end of the gear rod 11 is fixedly connected to the center of the adjusting gear 10;

[0035] The driving assembly includes a chain 12, and each set of gear rods 11 is provided with a sprocket, and each set of sprockets is sleeved with the same set of chains 12; a first motor 13 is provided on the rear side of the adjusting disk 9, and the output end of the first motor 13 is connected to one set of gear rods 11;

[0036] In this embodiment, the first motor 13 drives one group of gear rods 11 to rotate, and the gear rod 11 drives the gear rods 11 in the remaining speed gears to rotate synchronously through the sprocket and the chain 12, thereby driving multiple groups of adjusting gears 10 to rotate; and because of the transmission method of the chain 12, the linear speeds of the multiple groups of adjusting gears 10 can be consistent, and the angular speeds of the multiple groups of speed gears with different tooth ratios are different, thereby driving the main gear 7 to rotate at different angles, and then driving the bending angles of the metal wire to be different, so that the bending stress on the metal wire is different.

[0037] Preferably, the clamping assembly 5 includes two groups of symmetrically arranged clamping rods; the clamping rod includes a mounting plate 501, the mounting plate 501 is fixedly arranged on the front side of the turntable 3, a screw 502 is passed through the mounting plate 501, and the screw 502 is threadedly connected to the mounting plate 501; the adjacent ends of the two groups of screws 502 are respectively provided with clamping plates 503 for clamping the metal wire, and the other ends are respectively provided with friction wheels 504;

[0038] In the process of testing the bending performance of the metal wire, the metal wire is first passed through the two sets of guide components 4, and then the clamping component 5 is adjusted to clamp and fix the metal wire;

[0039] Specifically, since the screw rod 502 is threadedly connected to the mounting plate 501, the rotation of the screw rod 502 will produce movement; therefore, in clamping and fixing the metal wire, the worker rotates the two sets of screw rods 502 respectively through the friction wheels 504 at both ends of the two sets of screw rods 502, so that the two sets of clamping plates 503 at the ends of the two sets of screw rods 502 are close to each other to clamp on the outer periphery of the metal wire, thereby achieving clamping of the metal wire.

[0040] Preferably, the guide assembly 4 includes a support rod 401, and the adjacent ends of the two groups of support rods 401 are rotatably connected to the guide wheels 402, and the other ends are fixedly connected to the vertical plates 2;

[0041] The support rod 401 includes a main rod 4011, a sliding hole is provided in the main rod 4011, a sliding rod 4012 is slidably provided in the sliding hole, the sliding rod 4012 passes through the main rod 4011 and is exposed outward, the end of the sliding rod 4012 away from the sliding rod 4012 is rotatably connected to the guide wheel 402, a spring 4013 is provided in the sliding hole, one end of the spring 4013 is connected to the sliding rod 4012, and the other end is connected to the main rod 4011;

[0042] In the process of testing the bending performance of the metal wire, the metal wire needs to be passed between the two sets of guide components 4;

[0043] Specifically, one end of the metal wire is passed through the two sets of guide wheels 402. As the metal wire is passed through the guide wheels 402, the slide bar 4012 moves and compresses the spring 4013, and the spring 4013 ensures that the guide wheels 402 can tightly clamp the metal wire through its restoring force; and the elasticity of the spring 4013 itself can meet the needs of clamping metal wires of different models, thereby improving the applicability of the device.

[0044] Preferably, a working groove is provided at a portion of the base 1 located below the guide wheel 402 , and the metal wire can pass through the working groove and pass between the two sets of guide assemblies 4 and be clamped by the clamping assembly 5 .

[0045] When in use, in order to simulate the outdoor use state of the metal wire, multiple groups of speed gears with different gear ratios can be meshed with the main gear 7 in sequence; specifically, the electric telescopic rod 8 is first driven to retract to release the meshing relationship between the main gear 7 and the speed gear, and the second motor 14 is started to drive the adjustment disk 9 to rotate, so that another group of adjustment gears 10 is adjusted to a state that can mesh with the main gear 7; then, the electric telescopic rod 8 is driven again to drive the adjustment gear 10 to mesh with the main gear 7 to drive the turntable 3; since each group of speed gears has the same linear speed but different tooth ratios, their own angular velocities are different, so the angles of driving the main gear 7 to rotate are different, and then the bending angles of driving the metal wire are different, so that the bending stresses on the metal wire are different; therefore, by using multiple groups of speed gears to mesh with the main gear 7 respectively, various bending conditions of the metal wire caused by changes in wind speed in outdoor environments can be effectively simulated, so as to comprehensively evaluate its durability and reliability in practical applications.
