Description

Technical Field

[0001] This utility model relates to the field of wire feeding machine technology, specifically a multi-head wire feeding machine that can be numerically controlled. Background Technology

[0002] Multi-head CNC-operated wire feeding machines are indispensable equipment in many industrial fields such as wire and cable, textiles, and metal processing. They achieve precise control of the multi-head wire feeding process through advanced CNC technology. In the wire and cable production process, multi-head CNC-operated wire feeding machines can process multiple wire cores at the same time. The core of this is to achieve independent control and coordinated operation of multiple wire feeding heads through the CNC system.

[0003] However, during use, multiple wires need to be cut manually during the laying process. Manually cutting multiple wires requires operators to complete the task one by one, which is time-consuming and cannot meet the needs of high-speed production. The accuracy of manual cutting is limited and may result in deviations. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Example 1

[0022] This utility model provides a technical solution: such as Figure 1-3 As shown, a multi-head CNC-operable wire feeding machine includes a multi-head wire feeding mechanism 100 and a cutting assembly 200. The cutting assembly 200 includes a cutting worktable 202, one end of which is fixedly installed at one end of the multi-head wire feeding mechanism 100. A guide rail groove 204 is formed inside one end of the cutting worktable 202. A sliding block 211 is slidably connected inside the guide rail groove 204. A first cutting blade 207 and a second cutting blade 210 are fixedly installed on the upper end of the sliding block 211. One end of the cutting blade 207 is equipped with a telescopic guide post 206, and one end of the telescopic guide post 206 is equipped with a push hydraulic cylinder 201. One end of the push hydraulic cylinder 201 is installed on one end of the support plate 203. The lower end of the support plate 203 is set on the upper end of the cutting worktable 202. The upper end of the first cutting blade 207 is rotatably connected to a first connecting rod 208. One end of the first connecting rod 208 is rotatably connected to one end of a second connecting rod 209. One end of the second connecting rod 209 is rotatably connected to the upper end of the second cutting blade 210.

[0023] In actual use, the multi-head wire feeding mechanism 100 is first activated to release the wires from multiple spools, ensuring that each wire has appropriate tension and feeding speed. When each wire is finished feeding, the hydraulic cylinder 201 is driven to move the telescopic guide column 206, which in turn moves the first cutting blade 207, causing the first connecting rod 208 and the second connecting rod 209 to rotate. When the second connecting rod 209 rotates, it in turn moves the second cutting blade 210, so that the first cutting blade 207 and the second cutting blade 210 move relative to each other, enabling multiple cables to be cut simultaneously, reducing manual individual cutting.

[0024] This embodiment enables the simultaneous cutting of multiple cables. Compared to traditional single-cable cutting, it reduces the time required for each individual cable cutting cycle, thereby improving overall production efficiency, reducing production problems caused by human error, ensuring the accuracy of each cut, and avoiding deviations due to the limited precision of manual cutting.

[0025] Example 2

[0026] like Figure 1-2 , Figure 4 As shown, the cutting worktable 202 has a sliding groove 205 inside, and a moving block 307 is slidably connected inside the sliding groove 205. The upper end of the moving block 307 is provided with a first clamping rod 308 and a second clamping rod 309. The moving block 307 is rotatably connected with a first lead screw 305 and a second lead screw 306. The first lead screw 305 and the second lead screw 306 are provided with forward and reverse lead screws. The upper end of the moving block 307 is equipped with a first clamping rod 308, and the first clamping rod 308 is shown to have a forward movement trajectory.

[0027] like Figure 4 As shown, a second clamping rod 309 is installed on the upper end of the moving block 307, and the second clamping rod 309 moves in the opposite direction. A first gear 302 is installed on one end of the second lead screw 306. A transmission belt 303 is provided on the outer side of the first gear 302. The inner side of the transmission belt 303 is meshed with the outer side of the second gear 304. A first lead screw 305 is installed on one end of the second gear 304. A rotating shaft 301 is installed on one end of the first gear 302. A servo motor 300 is installed on one end of the rotating shaft 301.

[0028] In actual use, the servo motor 300 starts, the rotating shaft 301 starts to rotate, the first gear 302 drives the second gear 304 to rotate through the transmission belt 303, and then drives the first lead screw 305 and the second lead screw 306. The rotation of the lead screw drives the moving block 307 to move in the sliding groove 205. The first clamping rod 308 and the second clamping rod 309 on the moving block 307 move along the forward and reverse trajectories respectively. The first clamping rod 308 and the second clamping rod 309 clamp the material and maintain its stability. The clamping rods ensure that the wire can be stably positioned on the cutting worktable 202.

[0029] In this embodiment, the first clamping rod 308 and the second clamping rod 309 can clamp and fix the wire, ensuring that the position of the wire on the cutting worktable 202 is always stable, avoiding cutting errors caused by unstable cutting or displacement of the wire. By moving the first clamping rod 308 and the second clamping rod 309 along the forward and reverse trajectories respectively, a more balanced clamping force can be provided, which can maintain its stability during the cutting process and prevent deviation or deformation.

[0030] This utility model provides a multi-head CNC-operated wire feeding machine. Its specific working principle is as follows: Started by a servo motor 300, the rotating shaft 301 begins to rotate. The first gear 302 drives the second gear 304 to rotate via a transmission belt 303, which in turn drives the first lead screw 305 and the second lead screw 306. The rotation of the lead screws causes the moving block 307 to move within the sliding groove 205. The first clamping rod 308 and the second clamping rod 309 on the moving block 307 move along forward and reverse trajectories, respectively. The first clamping rod 308 and the second clamping rod 309 clamp the material and maintain its stability. The clamping rods ensure that the wire can be placed on the cutting worktable 202. For stable positioning, the multi-head wire feeding mechanism 100 is first activated to release the wires from multiple spools, ensuring that each wire has appropriate tension and feeding speed. When each wire is finished feeding, the hydraulic cylinder 201 is driven to move the telescopic guide column 206, which in turn moves the first cutting blade 207. This causes the first connecting rod 208 and the second connecting rod 209 to rotate. When the second connecting rod 209 rotates, it in turn moves the second cutting blade 210, so that the first cutting blade 207 and the second cutting blade 210 move relative to each other, enabling the simultaneous cutting of multiple cables and reducing manual individual cutting.
