Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] like Figure 1~Figure 4As shown, this embodiment proposes a frame-type wire twisting machine for cable processing, including: a twisting cage 1, a wheel disc 2, a base frame 3, a brake wheel 4, a braking mechanism and a driving mechanism. Two wheel discs 2 are provided, and the two wheel discs 2 are fixedly connected to the twisting cage 1. Braking grooves are provided on the two wheel discs 2. The two wheel discs 2 are rotatably connected in the base frame 3. There are multiple brake wheels 4, and the multiple brake wheels 4 are arranged in the base frame 3. Through the cooperation between the twisting cage 1, the wheel disc 2, the base frame 3, the brake wheel 4, the braking mechanism and the driving mechanism, it is convenient to brake the wheel disc 2 efficiently and stably. The brake wheel 4 and the brake shaft 5 are not easily subjected to strong friction, and high temperature is not easy to generate during braking, thereby improving the braking efficiency of the wheel disc 2.

[0041] Among them, there are two braking mechanisms, and the two braking mechanisms correspond to each two adjacent brake wheels 4 one by one. The braking mechanism includes: a brake shaft 5, a fixed frame 6, a slider 7, a spring 8 and a transmission component. There are multiple brake shafts 5, and the multiple brake shafts 5 are of different sizes. The multiple brake shafts 5 are divided into two groups. The two groups of brake shafts 5 are respectively fixedly connected to the two brake wheels 4. The multiple brake shafts 5 are engaged with the multiple brake grooves. The fixed frame 6 is fixedly connected in the base frame 3. There are two sliders 7, and the two sliders 7 are slidably set in the fixed frame 6. The two brake wheels 4 are respectively rotatably connected to the two sliders 7. The spring 8 is fixedly connected between the two sliders 7. The transmission component is set in the fixed frame 6 for transmitting the slider 7 to move. The transmission assembly includes: a transmission rod 9, a fixed seat 10 and a transmission wheel 11. There are two transmission rods 9, and the two transmission rods 9 are rotatably connected to the two sliders 7 respectively. The fixed seats 10 are fixedly connected to the two transmission rods 9 respectively. There are two transmission wheels 11, and the two transmission wheels 11 are rotatably connected in the two fixed seats 10 respectively. Specifically, the transmission wheel 11 moves in the fixed frame 6, thereby driving one end of the transmission rod 9 to move upward, thereby supporting the slider 7 slidingly arranged in the fixed frame 6 to move relatively, thereby driving the two brake wheels 4 to contact and clamp the wheel disc 2, so that the brake shaft 5 is engaged with the brake groove, and the wheel disc 2 is quickly braked by squeezing the brake shafts 5 of different sizes.

[0042] Among them, there are two driving mechanisms, and the two driving mechanisms correspond to the two braking mechanisms one by one, and are used to drive the braking mechanism to move. The driving mechanism includes: a driving frame 12, a driving wheel 13, a force block 14, a driving block 15 and a first electric cylinder 16. A plurality of lifting blocks 19 are fixedly connected to the driving block 15, and the plurality of lifting blocks 19 are provided with sliding holes. A plurality of sliding rods 20 are fixedly connected to the fixed frame 6, and the plurality of sliding rods 20 are respectively slidably set in the plurality of sliding holes. A slide rail 17 is fixedly connected to the base frame 3, a slide box 18 is fixedly connected to the driving block 15, and the slide rail 17 is slidably set in the slide box 18. The driving frame 12 is slidably set in the fixed frame 6 There are two driving wheels 13, both of which are rotatably connected to the driving frame 12, the force block 14 is fixedly connected to the driving frame 12, the driving block 15 is arranged in the fixed frame 6, the driving block 15 is in contact with the force block 14, the first electric cylinder 16 is arranged in the base frame 3, and the output end of the first electric cylinder 16 is fixedly connected to the driving block 15. Specifically, the driving block 15 is driven to move in the base frame 3 by the first electric cylinder 16 arranged in the base frame 3. When the driving block 15 moves, it drives the force block 14 to rise, thereby driving the driving frame 12 and the driving wheel 13 to rise, thereby driving the transmission rod 9 to swing upward, and then driving the slider 7 to move relatively.

[0043] In this embodiment, when the wheel disc 2 needs to be braked, the first electric cylinder 16 provided in the base frame 3 drives the driving block 15 to move in the base frame 3. When the driving block 15 moves, it drives the force-bearing block 14 to rise, thereby driving the driving frame 12 and the driving wheel 13 to rise, thereby driving the transmission rod 9 to swing upward. When the transmission rod 9 swings upward, it drives the transmission wheel 11 rotatably provided in the fixed seat 10 to rotate in the fixed frame 6, thereby supporting the slider 7 slidably provided in the fixed frame 6 to move relatively, thereby driving the two brake wheels 4 and The wheel disc 2 contacts and clamps, so that the brake shaft 5 meshes with the brake groove. Through the squeezing of the brake shafts 5 of different sizes, the brake shafts 5 arranged on the brake wheel 4 surround the brake wheel 4 from small to large. When the two brake wheels 4 are close to the wheel disc 2, the wheel disc 2 is between the two small brake shafts 5, and the brake shaft 5 meshes with the brake groove. When the wheel disc 2 rotates, it will drive the brake wheel 4 to rotate. When the two large brake shafts 5 rotate to relative to each other, the clamping force of the wheel disc 2 increases, making it difficult for the wheel disc 2 to rotate, and then the wheel disc 2 is quickly braked.
