DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0028] First embodiment:

[0029] like Figure 1-4As shown, the automatic wire trimming mechanism provided by the utility model includes: a wire trimming mechanism 100 and a wire trimming fixing assembly 200, the wire trimming mechanism 100 includes a wire trimming platform 102, the upper end of the wire trimming platform 102 is connected and fixed with a first fixed moving rod 201 and a second fixed moving rod 202 by bolts, the first fixed moving rod 201 and the second fixed moving rod 202 are provided with a moving groove 209, the inside of the moving groove 209 is penetrated and connected with a first fixed clamping slider 205 and a second fixed clamping slider 206, the lower ends of the first fixed clamping slider 205 and the second fixed clamping slider 206 are connected and fixed with a moving slide bar 214 by welding, the upper ends of the first fixed moving rod 201 and the second fixed moving rod 202 are connected and fixed with a first linear fixed block 203 and a second linear fixed block 204 by bolts, the inside of the first fixed moving rod 201 and the second fixed moving rod 202 is penetrated and connected with a threaded screw 207, One end of the threaded rod 207 is connected and fixed to the servo motor 208 by bolts, and the lower end of the servo motor 208 is connected and fixed to the mounting support platform 104 by bolts. The mounting support platform 104 is connected to one side end of the wire cutting platform 102 by welding. In actual use, when the staff places the wire body 109 on the curved surfaces of the first linear fixed block 203 and the second linear fixed block 204, the threaded rod 207 is driven to rotate by driving the servo motor 208, and the first fixed clamping slider 205 and the second fixed clamping slider 206 are further driven to move, and move on the first fixed moving rod 201 and the second fixed moving rod 202. The wire body 109 can be clamped and fixed by moving the first fixed clamping slider 205 and the second fixed clamping slider 206, and the wire cutting is cut from the middle section of the wire body 109. By clamping and fixing both ends of the wire body 109, it can be avoided that the wire body 109 moves or deviates during cutting to cause inaccurate size.

[0030] In this embodiment, by using the wire trimming fixing assembly 200, the two ends of the wire body 109 are clamped by two clamping sliders, so that the wire body 109 can be ensured to remain stable during the cutting process without moving or offsetting. This helps to improve the dimensional accuracy of the wire body 109 after cutting. By adjusting the parameters of the servo motor 208, the position of the clamping slider can be changed to adapt to wire bodies 109 of different lengths and diameters. This makes the device have good versatility and adaptability, which can reduce the chance of people directly contacting the wire body 109 and reduce the safety risks that workers may face during operation.

When the first fixed clamping slider 205 and the second fixed clamping slider 206 move, when the fixed clamping slider moves and contacts with the limiting column 213, the moving speed of the first fixed clamping slider 205 and the second fixed clamping slider 206 can be buffered by the limiting column 213 and the first spring 211, so that deformation or damage caused by the movement and clamping of the wire body 109 can be avoided.

[0033] In this embodiment, by utilizing the sleeve 210 and the first spring 211, when the first fixed clamping slider 205 and the second fixed clamping slider 206 move toward the limiting column 213, the first spring 211 is squeezed and contracted, thereby playing a buffering role, thereby reducing the impact force when the slider contacts the limiting column 213, and preventing deformation or damage of the wire body 109 due to too fast movement.

[0034] Third embodiment:

[0035] like Figure 1-2 , Figure 7-8 As shown, the wire trimming fixing assembly 200 is arranged at the position of the automatic wire trimming assembly 300, and the automatic wire trimming assembly 300 includes a lifting hydraulic cylinder 301, and the lifting hydraulic cylinder 301 is connected and fixed to the support plate 101 by bolts, and the support plate 101 is connected to the upper end of the wire trimming platform 102 by welding, and the lower end of the lifting hydraulic cylinder 301 is connected and fixed to the lifting guide column 302 by bolts, and the lower end of the lifting guide column 302 is connected and fixed to the wire trimming blade 303 by bolts, and a wire trimming protection plate 304 is provided below the wire trimming blade 303, and a knife edge groove 304 is provided inside the wire trimming protection plate 304. 5. The lower end of the knife groove 305 is connected and fixed to the groove plate 306 by welding. The lower end of the groove plate 306 is provided with a blade hole groove 312. When the wire body 109 is clamped and fixed, the lifting guide column 302 and the wire cutting blade 303 are driven to move by driving the lifting hydraulic cylinder 301, and the wire body 109 is further cut. The wire cutting blade 303 has a certain inertia effect, and then the wire cutting blade 303 enters the interior of the wire cutting protection plate 304. The wire cutting protection plate 304 is made of rubber material, which can reduce the wear of the wire cutting blade 303.

[0036] Fourth embodiment:

The inside of the oil cylinder 311 is provided with buffer oil liquid which can absorb and slow down the impact force of the wire cutting blade 303. In actual use, when the operator places the wire body 109 on the wire cutting platform 102 and starts the wire cutting blade 303 to cut the wire body 109, the wire cutting blade 303 will have an impact force. When the wire cutting blade 303 cuts the wire body 109, it will enter the blade groove 305 of the wire cutting protection plate 304 and move downward. The wire cutting protection plate 304, the piston guide column rod 310 and the oil cylinder 311 can reduce the absorption of the impact force of the wire cutting blade 303. When the wire cutting blade 303 moves upward, the second spring 308 will rebound the wire cutting protection plate 304 to its original position, which can reduce and avoid damage to the blade of the wire cutting blade 303.

[0038] In this embodiment, by utilizing the fixed block and the second spring 308, the oil cylinder 311 and the piston guide rod 310, the wire cutting protection plate 304, and the wire cutting blade 303, a certain impact force will be generated when cutting the wire body 109. After completing the cutting action, the wire cutting blade 303 can enter the blade groove 305 of the wire cutting protection plate 304 and move downward, which can further reduce the impact force absorbed by the wire cutting blade 303. The impact force is absorbed and relieved by the compression of the oil cylinder 311, thereby protecting the tool from damage, reducing and avoiding damage to the blade of the wire cutting blade 303, and ensuring stability and processing quality during the cutting process of the wire body 109.

The wire cutting mechanism 100 can be easily moved through the wheel 107.

[0041] When in use, first, the staff places the wire body 109 on the curved surfaces of the first linear fixed block 203 and the second linear fixed block 204, and then drives the servo motor 208 to drive the threaded screw 207 to rotate, and further drives the first fixed clamping slider 205 and the second fixed clamping slider 206 to move, and move on the first fixed moving rod 201 and the second fixed moving rod 202.
