Description

Technical Field

[0001] The utility model relates to the technical field of cable manufacturing, and particularly relates to a pressure device for cable extrusion. Background Technique

[0002] A cable is a wire made of one or more mutually insulated conductors wrapped with an insulating and protective layer, which transmits electricity or information from one place to another; a cable consists of a conductor, an insulating layer, and a protective layer; taking a power cable as an example, when both ends of the cable are connected to a power source and a load, free electrons in the conductor move directionally under the action of an electric field to form an electric current, and the insulating layer isolates the conductor from the outside world to prevent the electric current from leaking into the surrounding environment and ensure that the electric current is transmitted along the inside of the conductor. In a communication cable, signals are transmitted in the form of electromagnetic waves or electrical pulses in the conductor; signals of different frequencies or encodings are transmitted through different conductors or core wires, and the insulating layer plays a role in isolating different signal channels to prevent interference between signals. A control cable transmits various control signals, such as switch signals, adjustment signals, etc., according to the requirements of the control system to achieve precise control and operation of electrical equipment.

[0003] During the cable production process, in order to ensure the quality and performance of the cable, the cable is generally extruded to ensure that the insulating material can tightly wrap around the conductor. Generally, a pressure device is used to extrude the cable. At present, most extrusion devices use a pressure application mechanism to apply pressure to the cable. However, most cables are circular, so the pressure application mechanism needs to apply pressure around the cable, which requires friction on the outside of the cable, easily causing relatively large friction on the outside of the cable and having poor practicability. Therefore, in order to solve the above problems, a pressure device for cable extrusion is hereby proposed. Content of the Utility Model

Detailed Embodiment

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3, A pressure device for cable extrusion, including a mounting plate 1, a cable pressing mechanism, and a support mechanism. The cable pressing mechanism includes a setting plate 2. On one side of the setting plate 2, a motor 3 is fixedly installed. The output end of the motor 3 is fixedly connected to a gear 4. Above the gear 4, a toothed ring 5 is hinged. Inside the toothed ring 5, a rotating ring 6 is fixedly connected. Inside the rotating ring 6, an electric push rod 7 is fixedly installed. One end of the electric push rod 7 is fixedly connected to a pressure sensor 8. Below the pressure sensor 8, a connecting plate 9 is fixedly connected. On one side of the connecting plate 9, a connecting rod 10 is fixedly connected. One end of the connecting rod 10 is fixedly connected to a first slider 11. Outside the first slider 11, a pressure wheel 12 is provided. Inside the pressure wheel 12, a first chute 13 is opened. On the surface of the pressure wheel 12, a pressure groove 14 is opened. The setting plate 2 is fixedly connected to the upper side of the mounting plate 1. The first slider 11 is arranged inside the first chute 13 and is slidably connected to the first chute 13. The cable is arranged between the two pressure wheels 12. The elongation of the electric push rod 7 will push the pressure sensor 8 towards the cable. When the electric push rod 7 pushes the pressure sensor 8, the pressure sensor 8 transmits the pressure to the connected connecting plate 9, so that the cable is arranged in the pressure grooves 14 on the surfaces of the two pressure wheels 12. The two pressure wheels 12 will extrude the cable from both sides to achieve the pressure application process on the cable. The pressure sensor 8 can monitor the pressure application situation in real time to ensure that the pressure meets the requirements. The motor 3 drives the gear 4 to start rotating. The gear 4 is hinged to the toothed ring 5. When the gear 4 rotates, the gear 4 will drive the toothed ring 5 to perform a rotational movement. The toothed ring 5, as an intermediate transmission component, transmits the power to the connected rotating ring 6, and the rotating ring 6 also rotates accordingly. The first slider 11 is arranged in the first chute 13 inside the pressure wheel 12, and the first slider 11 slides in the first chute 13, so that when extruding the cable, the two pressure wheels 12 will rotate, thereby reducing the external friction on the cable.

[0020] In one aspect of this embodiment, a vertical plate 15 is fixed on the mounting plate 1 to provide a stable installation foundation for the guide rod 16. The vertical plate 15 is arranged on both sides of the rotating ring 6 to play a role in supporting and fixing the guide rod 16. Inside the rotating ring 6, a second chute 18 is opened. A second slider 17 at the end of the guide rod 16 on one side of the vertical plate 15 is arranged inside the second chute 18. When the rotating ring 6 rotates driven by the toothed ring 5, the second slider 17 slides in the second chute 18. On the one hand, the second slider 17 moves with the rotation of the rotating ring 6, and on the other hand, it plays a supporting role for the rotating ring 6 to prevent the rotating ring 6 from shaking or shifting during the rotation process, ensuring the stability of the entire device during operation. On one side of the vertical plate 15, a handle 19 is also fixedly connected, which is convenient for assisting in lifting the device when lifting and moving the device.

[0021] In one aspect of this embodiment, a fixing hole 23 is penetrated through the surface of the fixing plate 22. By passing a bolt or other fixing member through the fixing hole 23, the mounting plate 1 can be firmly fixed at the required working position, ensuring that the entire device will not move or shake during operation. A rubber pad 20 is fixedly connected to the lower side of the mounting plate 1. The rubber pad 20 has good anti-slip performance. When the mounting plate 1 is placed on the working plane, the rubber pad 20 can increase the friction with the working plane, preventing the device from sliding due to external force or vibration during operation. The rubber pad 20 also has a certain shock-absorbing effect. During the operation of the device, certain vibrations will be generated, and the rubber pad 20 can absorb and buffer these vibrations, reducing the impact of vibrations on the device and the surrounding environment, ensuring the running stability and reliability of the device. At the same time, a number of linearly distributed texture grooves 21 opened on the lower surface of the rubber pad 20 further enhance the anti-slip effect of the rubber pad.

[0022] The working principle of the present utility model: When this pressure device for cable extrusion is in use, the cable is arranged at the position between the two pressure wheels 12. The elongation of the electric push rod 7 will push the pressure sensor 8 to move towards the cable. When the electric push rod 7 pushes the pressure sensor 8, the pressure sensor 8 transmits the pressure to the connecting plate 9 connected thereto, so that the cable is arranged in the pressure grooves 14 on the surfaces of the two pressure wheels 12. The two pressure wheels 12 will extrude the cable from both sides to achieve the pressure application process for the cable. The pressure sensor 8 can monitor the pressure application situation in real time to ensure that the pressure meets the requirements. The motor 3 drives the gear 4 to start rotating. The gear 4 is hinged with the toothed ring 5. When the gear 4 rotates, the gear 4 will drive the toothed ring 5 to perform a rotational motion. The toothed ring 5, as an intermediate transmission component, transmits the power to the rotating ring 6 connected thereto, and the rotating ring 6 also rotates accordingly to perform a rotational extrusion process on the cable. The second slider 17 at the end of the guide rod 16 on one side of the vertical plate 15 is arranged in the second chute 18. When the rotating ring 6 rotates driven by the toothed ring 5, the second slider 17 slides in the second chute 18. On the one hand, the second slider 17 moves along with the rotation of the rotating ring 6, and on the other hand, it plays a supporting role for the rotating ring 6 to prevent the rotating ring 6 from shaking or shifting during the rotation process, ensuring the stability of the entire device during operation. In this solution, all electrical equipment is powered by an external power supply.

[0023] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
