Description
Technical Field
[0001] This utility model relates to the field of automatic cable straightening technology, and in particular to an automatic straightening machine for cold-resistant cables. Background Technology
[0002] Cold-resistant cables are special cables designed for extreme low-temperature environments. They have excellent cold resistance and some can operate normally in extremely low-temperature environments. Their insulation and sheath are made of low-temperature elastic materials to ensure that they remain flexible at low temperatures. They are also soft, wear-resistant, oil-proof, and corrosion-resistant. They have stable electrical performance and are widely used in infrastructure construction in cold regions, outdoor renewable energy facilities, oil and gas extraction and transportation, and winter maintenance of railways and roads. They are especially suitable for working conditions with large day-night temperature differences in high-altitude and cold regions.
[0003] Existing straightening machines have significant technical flaws. The fixed spacing design of the roller sets cannot accommodate the straightening requirements of cables with different diameters. This results in thinner cables bending excessively between the rollers, while thicker cables are squeezed and deformed due to insufficient gaps. Consequently, even after straightening, the cables still exhibit micro-bending and are prone to surface indentations. These problems are particularly severe in cold-resistant cable applications, as low temperatures exacerbate the embrittlement of materials. Insufficient release of residual stress can lead to micro-cracks or insulation layer ruptures in cables under dynamic bending conditions (such as freeze-thaw cycles in infrastructure in cold regions), thereby affecting their oil and corrosion resistance and electrical stability. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides an automatic straightening machine for cold-resistant cables, which aims to improve the problems described in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic cold-resistant cable straightening machine includes a machine body. Multiple clamping mechanisms are fixedly connected to the top of the machine body. A cleaning mechanism is fixedly connected to the left side of the machine body. A top plate is fixedly connected to the top of the machine body. Each clamping mechanism includes a base. A turntable is rotatably connected to the top of the base.

[0006] As a further description of the above technical solution: the telescopic component includes a base block one, a fixed post is fixedly connected to one side of the base block one, a threaded rod one is threadedly connected to one side of the fixed post, a wooden board is fixedly connected to the right side of the threaded rod one, a rotating post is fixedly connected to one side of the wooden board, a base block two is threadedly connected to the outside of the threaded rod one, and a spring is sleeved on the outside of the threaded rod one.

[0008] As a further description of the above technical solution: the inner wall of the roller is movably connected to the outer wall of the clamping plate; the inside of the turntable is provided with a groove; the outer wall of the moving column is slidably connected to the inner wall of the groove; the bottom of the square column is fixedly connected to the top of the first base block; the outer wall of the connecting column is slidably connected to the inner wall of the limiting plate; the right side of the fixed column is fixedly connected to the left side of the spring; the left side of the second base block is fixedly connected to the right side of the spring; the bottom of the base is rotatably connected to the top of the machine body; the base is provided with a groove; the outer wall of the handle is slidably connected to the inside of the groove; the bottom of the first base block is slidably connected to the inside of the machine body; the top of the first base block is slidably connected to the bottom of the top plate.
[0009] This utility model has the following beneficial effects: 1. In this utility model, the flexible clamping of the mold is achieved through the precise matching of the clamping structure. The turntable is connected to the machine body through the base and can rotate around the axis to adjust the angle. The turntable has a groove of a specific shape inside. The moving column slides along the groove, driving the slider and clamping plate to achieve radial displacement. The handle is directly connected to the turntable. The operator can precisely control the opening and closing degree of the clamping plate by rotating the handle. The bottom block one and bottom block two of the telescopic component are connected by a threaded rod. The spring is installed between bottom block two and the fixed column to form an elastic buffer system. The roller is installed on the top of the cover and forms a conveying channel with the clamping plate to ensure that the cable can still move smoothly in the clamping state. This multi-structure collaborative design enables the equipment to automatically adapt to molds of different diameters, ensuring clamping force while avoiding damage to the mold surface, thereby maintaining the low-temperature flexibility and surface integrity of the insulation layer, reducing the risk of micro-bending, and extending the service life of the cable in frozen soil environments.
[0010] 2. In this utility model, the cleaning mechanism adopts a unique mechanical transmission system to achieve efficient cleaning of the cable surface. The motor is fixed on the base plate through the support plate and drives the disc to rotate. The connecting column transmits the rotational motion of the disc to the limiting plate. Under the guidance of the limiting block, the limiting plate makes precise reciprocating linear motion. The connecting rod connects the limiting plate and the cylinder and transmits the linear motion to the brush assembly. The threaded rod two cooperates with the support block to precisely adjust the working angle of the brush. The square column provides rigid support for the entire cleaning mechanism to ensure motion stability. The bottom block one slides inside the base plate, so that the cleaning mechanism can move with the cable and maintain the optimal working position. This multi-stage transmission structure ensures that the brush can thoroughly remove debris from the cable surface and inside the equipment, ensure the cleaning of the anti-corrosion coating covering the cable sheath, prevent impurities from embedding into the surface indentation during the straightening process, and ensure the long-term stable operation of the cable under extreme temperature differences.

[0018] Working principle: The mold is placed in the clamping plate 25. The clamping plate 25 achieves flexible clamping under the linkage of the turntable 22 and the slider 23. The threaded rod 33 of the telescopic component 3 generates axial displacement through the threaded connection between the bottom block 31 and the fixed column 32, which drives the wooden board 34 and the rotating column 35 to apply precise traction force to the cable. The buffer system composed of the bottom block 36 and the spring 37 compensates for pressure fluctuations in real time to ensure uniform force during the straightening process. The roller 28 assists in the smooth transport of the cable under the support of the upper cover 27. The moving column 24 slides along the internal groove of the turntable 22, so that the entire clamping mechanism 2 can adapt to cables of different diameters and achieve straightening without damage.
[0019] During the cleaning phase, the motor 43 of the cleaning mechanism 4 drives the disc 44 to rotate. The connecting column 412 drives the limiting plate 45 to reciprocate along the limiting block 413 outside the support plate 42. The connecting rod 46 converts the rotational motion of the disc 44 into the linear motion of the cylinder 47, which drives the brush 48 to thoroughly clean the surface of the cable. The threaded rod 49 adjusts the angle of the brush 48 through the support block 410. The square column 411 provides rigid support for the entire cleaning mechanism 4. The bottom block 31 slides inside the bottom plate 41, allowing the cleaning mechanism 4 to follow the cable and ensure that there are no dead corners in the removal of debris. This mechanical linkage design realizes the real-time cleaning of debris during the straightening process and effectively maintains the cleanliness of the equipment.
