[0031] like Figure 1 and Figure 4As shown in the figure, this embodiment provides a cutting and bending device for wire harness production, including a base 1, a cutting component 2 on the top of the base 1, a bending component 3 at one end of the base 1, and a collecting component 4 inside the base 1.
[0032] The cutting assembly 2 includes a motor 21, which is located at the other end of the base 1. The output end of the motor 21 is connected to a bidirectional threaded rod 22, and the threads at both ends of the bidirectional threaded rod 22 are in opposite directions. The bidirectional threaded rod 22 is rotatably connected to the base 1. A slide table 23 is symmetrically arranged on the bidirectional threaded rod 22, and the bidirectional threaded rod 22 is threadedly connected to the slide table 23. A second V-groove 24 is opened on the top of the slide table 23, and a guide block 25 is provided at the bottom of the slide table 23.

A cutting mechanism is provided on the top of the base 1 between the two slide tables 23. The motor 21 drives the bidirectional threaded rod 22 to rotate, and the bidirectional threaded rod 22 drives the two slide tables 23 to move in opposite directions. The two slide tables 23 stretch the wire harness, which helps with the subsequent cutting operation.
[0033] The first clamping mechanism includes a first U-shaped plate 271, which is located on the top of the slide table 23. A threaded rod 272 is threadedly connected to the first U-shaped plate 271.

A first V-shaped extrusion block 273 is located at the bottom of the second guide rod 274. The first V-shaped extrusion block 273 is rotatably connected to the threaded rod 272. The turntable 275 drives the threaded rod 272 to rotate, and the threaded rod 272 pushes the first V-shaped extrusion block 273 to move downward along the second guide rod 274. The first V-shaped extrusion block 273 performs the function of extruding and fixing the wire harness.
[0034] The cutting mechanism includes a second U-shaped plate 281, which is located on the top of the base 1 and between two slides 23. A first cylinder 282 is provided on the top of the second U-shaped plate 281. The output end of the first cylinder 282 is connected to a connecting plate 283. A cutter 284 is provided at the bottom of the connecting plate 283. A first sliding groove 286 is symmetrically opened on the inner wall of the second U-shaped plate 281. A first sliding rod 285 is provided inside the first sliding groove 286. The first sliding rod 285 is slidably connected to the connecting plate 283. The cutter 284 at the bottom of the connecting plate 283 is pushed downward by the first cylinder 282, and the wire harness is cut by the cutter 284.
[0035] The base 1 has a first V-shaped groove 101 on its top, and square grooves 102 are symmetrically provided inside the base 1. The first guide rod 26 is located inside the square groove 102, and the slide table 23 is located inside the square groove 102. The base 1 has an anti-collision groove 103 on its top, which is located below the cutter 284. The anti-collision groove 103 plays a role in preventing the cutter 284 from colliding, and at the same time plays a role in guiding waste.
[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the bending assembly 3 includes a third U-shaped plate 31, which is located on the top of the base 1. A second cylinder 32 is located on the top of the third U-shaped plate 31. The output end of the second cylinder 32 is fixedly connected to the bending block 33. A third guide rod 34 is symmetrically located on the top of the bending block 33. The third guide rod 34 is slidably connected to the third U-shaped plate 31. A limiting plate 35 is located on the top of the third guide rod 34. A second pressing mechanism is located on the top of the third U-shaped plate 31. The bending block 33 moves downward through the second cylinder 32, and the bending block 33 performs bending operations on the wire harness. This eliminates the need for manual bending and reduces the labor intensity of manual labor.
[0037] The second clamping mechanism includes a third cylinder 361, which is located on the top of the third U-shaped plate 31. The output end of the third cylinder 361 is fixedly connected to the second V-shaped extrusion block 362. The inner wall of the third U-shaped plate 31 is symmetrically provided with second sliding grooves 363. The second sliding grooves 363 are provided with second sliding rods 364 inside. The second sliding rods 364 are slidably connected to the second V-shaped extrusion block 362. The third cylinder 361 pushes the second V-shaped extrusion block 362 to move downward along the second sliding rod 364, thereby clamping and fixing the wire harness.
[0038] like Figure 1 and Figure 3 As shown, the collection component 4 includes a sliding groove 41, which is located inside the base 1 and is connected to the anti-collision groove 103. A collection frame 42 is provided inside the sliding groove 41, and a handle 43 is provided at one end of the collection frame 42. The cut waste is collected through the collection frame 42, and the collection frame 42 is pulled out from the sliding groove 41 through the handle 43, which prevents the waste from scattering everywhere and greatly reduces the difficulty of subsequent cleaning.
[0039] In use, the operator places the wire harness on the first V-groove 101 of the base 1. When cutting the wire harness, firstly, the turntable 275 is rotated, which drives the threaded rod 272 to rotate. The threaded rod 272 pushes the first V-shaped extrusion block 273 downward along the second guide rod 274, thus extruding and fixing the wire harness. Next, the motor 21 is started, which drives the bidirectional threaded rod 22 to rotate. The bidirectional threaded rod 22 drives the two slides 23 to move in opposite directions, stretching the wire harness and facilitating subsequent cutting operations. This avoids bending of the wire harness during cutting, thus not affecting its later use. Then, the first cylinder 282 is started, which pushes the connecting plate 283 downward along the first slide rod 285. The connecting plate 283 drives the cutter 284 downward. The wire harness is cut by the blade 284, and the cut waste falls into the collection box 42 through the anti-collision groove 103. The collection box 42 collects the cut waste. The worker pulls the handle 43, which pulls the collection box 42 out of the sliding groove 41, preventing the waste from scattering everywhere. This greatly reduces the difficulty and time of subsequent cleaning and improves work efficiency. When the wire harness needs to be bent, the worker first starts the third cylinder 361. The third cylinder 361 pushes the second V-shaped extrusion block 362 to move downward along the second slide bar 364. The second V-shaped extrusion block 362 presses and fixes the wire harness. Finally, the second cylinder 32 is started, which drives the bending block 33 to move downward. The bending block 33 performs the bending operation on the wire harness. No manual bending is required, which reduces the labor intensity of workers and improves work efficiency.
[0040] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
