[0028] The extension member 4 includes a first sheave 41, a second sheave 42 and a sleeve 43. The first sheave 41, the second sheave 42 and the sleeve 43 are rotatably connected to the first fixed plate 2. The two first sheaves 41 are located at the same horizontal height. The lower side of the second sheave 42 cooperates with the upper sides of the two first sheaves 41. The sleeve 43 is arranged at the right front of the second sheave 42 and cooperates with the upper side of the second sheave 42.

[0029] Specifically, in this embodiment, the welding wire is sleeved on the fixed shaft 3, and passes through the first groove wheel 41, the second groove wheel 42 and the sleeve 43 in sequence, so as to initially straighten and guide the welding wire.

[0030] Reference Figure 1 , Figure 4 and Figure 5 The wire feeding component 5 includes a first motor 51, a first eccentric gear 52, two second eccentric gears 53 and a third slider 54, a first clamp 55 and a second clamp 56. The output shaft of the first motor 51 is rotatably connected to the first eccentric gear 52. The left and right sides of the first eccentric gear 52 are respectively meshed and connected to the second eccentric gears 53. The first eccentric gear 52 and the two second eccentric gears 53 are fixedly connected to the third slider 54. The third slider 54 is fixedly connected to the first clamp 55. The second clamp 56 is fixedly connected to the first fixed plate 2.

[0031] Specifically, in this embodiment, the first motor 51 is started to drive the first eccentric wheel 52 to rotate, the second eccentric wheel 52 drives the two second eccentric wheels 53 to perform reciprocating motion, and the two eccentric wheels 53 drive the third slider 54 and the first clamp 55 to perform reciprocating motion.

[0032] Reference Figure 1 The crack detection component 6 includes an eddy current detection probe 61, a bracket 62, a host 63 and a display screen 64. The eddy current detection probe 61 is fixedly connected to the bracket 62, the eddy current detection probe 61 signal is connected to the host 63, and the host 63 is fixedly connected to the display screen 64.

[0033] Specifically, in this embodiment, eddy current detection uses the principle of electromagnetic induction to perform crack inspection, which is an existing mature technology. The inspection result of the eddy current detection probe 61 will be transmitted to the host 63 through a signal. The host 63 receives the information from the eddy current detection probe 61 and images it on the display screen 64. By analyzing the image, it is checked whether there are cracks on the surface of the welding wire. The detection process is convenient and quick.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6The tensile detection component 7 includes a mounting frame 71, a first slider 73, a dynamometer 74, a second slider 75, a clamping assembly 9, a first fixed block 76, a second fixed block 77, a belt 78, a pulley 79 and a second motor 710. The mounting frame 71 is fixedly connected to the top of the fixed frame 3. A guide groove 72 is provided at the upper end of the mounting frame 71. Two symmetrical first sliders 73 are slidably provided on the inner side of the mounting frame 71. The dynamometers 74 are fixedly installed on the opposite side walls of the two first sliders 73. The traction end of the dynamometer 74 is fixedly connected to the second slider 75 sliding on the inner side of the mounting frame 71. The upper end of the second slider 75 is provided with a clamping assembly 9. The two second sliders 75 are respectively fixed to the two ends of the connecting piece belt 78 by the first fixed block 76 and the second fixed block 77. The belt 78 is rotatably connected to the pulley 79, and the pulley 79 is rotatably connected to the output shaft of the motor 710.

[0035] Specifically, in this embodiment, the clamping assembly 9 clamps the welding wire, starts the second motor 710, and drives the first fixed block 76 and the second fixed block 77 to move in opposite directions, thereby driving the first slider 73 to pull the dynamometer 74 to move, and the dynamometer 74 to pull the second slider 75 to move. By observing the value of the dynamometer 73, it can be determined whether the strength value of the welding wire meets the requirements, thereby completing the tensile test of the welding wire.

[0036] Reference Figure 1 A guide groove 72 is formed at the upper end of the installation frame 71 .

[0037] Specifically, in this embodiment, the first fixing block 76 and the second fixing block 77 can pass through the guide groove 72 to drive the first sliding block 73 to move.

[0038] Reference Figure 3 The clamping assembly 9 includes two clamping plates 91, a wedge-shaped push block 92, a clamping cylinder 93 and a second fixed frame 94. The wedge-shaped push block 92 is slidably connected to the clamping plate 91, the clamping cylinder 93 is fixedly connected to the wedge-shaped push block 92, and the wedge-shaped push block 92 is slidably connected to the second fixed frame 94.

[0039] Specifically, in this embodiment, two clamping plates 91 and a wedge-shaped push block 92 form a groove through which the welding wire can pass. By starting the clamping cylinder 93, the wedge-shaped push block 92 is driven to slide downward, so that the two clamping plates 92 move closer to the middle, thereby stably clamping the welding wire and realizing automatic clamping and fixing after the welding wire is pre-tightened, which is conducive to stable tensile testing.

[0040] Reference Figure 3 The wedge-shaped push block 92 is provided with two first protrusions 921 , and the clamping plate 91 is provided with a first sliding groove 922 matching the first protrusions 921 .

[0041] Specifically, in this embodiment, the wedge-shaped push block 92 can move up and down to push the two clamping plates 91 to move relative and oppositely.

[0042] Reference Figure 3 A second protrusion 923 is provided on the inner side of the end of the clamping plate 91 , and a second sliding groove 924 matching the sliding of the clamping plate 91 is provided on the second fixing frame 94 .

[0043] In this embodiment, the clamping plate 91 can be slidably connected to the second fixing frame 94.

[0044] Reference Figure 1 The second fixing plate 21 is provided with a through slot 2101 .

[0045] Specifically in this embodiment, the first clamp 55 can be pulled by the third slider 54 .

[0046] Reference Figure 4 The first clamp 55 and the second clamp 56 have the same structure. The first clamp 55 includes a pressure plate 551, a spring 552 and a fixing rod 553. The pressure plate 551 is rotatably connected to the fixing rod 553, one end of the spring 552 is fixedly connected to the fixing rod 553, and one end of the spring 552 is fixedly connected to the pressure plate 551.

[0047] Specifically, in this embodiment, the spring 552 can provide a thrust during the process of the pressing plate 551 transferring the welding wire, so that the first clamp 55 and the second clamp 56 can pre-tighten and transfer the welding wire.

[0048] Working principle: First, the welding wire is straightened through the extension member 4, and then the welding wire is detected by the eddy current detection probe 61, and the information is transmitted to the host 63 to be imaged on the display screen 64 to detect whether there are cracks and damages. When the statistical curve of wavelength change after detection is consistent with the template curve, it means that there are no cracks, unevenness or rust in the pipe. A section of welding wire is randomly selected through the wire feeding member to carry out the tensile test, and the first motor 51 is started to drive the first eccentric wheel 52 to rotate, and the second eccentric wheel 52 drives the two second eccentric wheels 53 to reciprocate, and the two eccentric wheels 53 drive the third slider 54 and the first clamp 55 to reciprocate, and the first clamp The tool 55 can therefore transfer the welding wire, and one end of the welding wire can be randomly selected for a tensile test. The first clamp 55 and the second clamp 56 are used in combination to transfer and pull the welding wire for tensioning, thereby ensuring that the welding wire maintains a stable tension state in the tensile detection component 7. The clamping assembly 9 clamps the welding wire, and starts the second motor 710 to drive the first fixed block 76 and the second fixed block 77 to move in the opposite direction, thereby driving the first slider 73 to pull the dynamometer 74 to move, and the dynamometer 74 pulls the second slider 75 to move. By observing the value of the dynamometer 73, it can be concluded whether the strength value of the welding wire meets the requirements, thereby completing the tensile test of the welding wire.
