Description

Technical Field

[0001] This utility model relates to the field of angle steel straightening technology, specifically a straightening machine for deformed angle steel in power transmission tower accessories. Background Technology

[0002] Angle steel, also known as angle iron, is a common building and decoration material with a right-angled cross-section. It is especially common in the construction of steel structure scaffolding. During production and construction, external collisions can easily cause angle steel or angle iron to bend and deform under stress. During handling, angle steel or angle iron is also prone to twisting and deformation due to uneven stress. Therefore, straightening machines are needed for straightening.

[0003] In the existing technology, many existing straightening devices lack automatic lubrication systems, often requiring manual application of lubricating oil periodically to maintain the lubrication of components such as rotating rods and bearings. This method is not only cumbersome and time-consuming, but also difficult to guarantee the timeliness and uniformity of lubrication. Manual application may result in applying too much or too little lubricating oil. Too much will cause lubricating oil waste and contamination, while too little will not effectively reduce friction and wear between components. In addition, manual application may also lead to forgetting to lubricate due to negligence, resulting in excessive wear of components, affecting the service life of the equipment and the stability of the straightening process.

[0004] In view of this, we have introduced a straightening machine for deformed angle steel in power tower accessories. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4This utility model provides a technical solution: a straightening machine for deformed angle steel of power tower accessories, including: a frame 1, a cylinder A6 is provided on the inner top wall of the frame 1, a lifting plate 4 is provided at the output end of the cylinder A6, and a concave frame A5 is provided at the bottom of the lifting plate 4.

[0028] A concave frame B9 is set on the inner bottom wall of the frame 1. A motor A10 is set on the side of the concave frame A5. The output end of the motor A10 is connected to a rotating rod A25. A first V-shaped straightening wheel 7 is set on the surface of the rotating rod A25 inside the concave frame A5. A flat straightening wheel 17 is set on one side of the first V-shaped straightening wheel 7.

[0029] Motor B18 is disposed on one side of concave frame B9. A rotating rod B26 is disposed at the output end of motor B18. A second V-shaped straightening wheel 8 for matching the first V-shaped straightening wheel 7 is disposed on the surface of rotating rod B26 inside concave frame B9.

[0030] The concave frame A5 is equipped with a lubrication mechanism. The pressure plate 20 of the lubrication mechanism drives the oil-absorbing sponge 16 to be compressed, so that the lubricating oil flows through the oil guide pipe 12 to the surface of the rotating rod A25 and the bearing A11 to form lubrication.

[0031] The lubrication mechanism includes a cavity 14 formed inside a concave frame A5. The cavity 14 and the concave frame A5 are integrally formed. A cylinder B24 is provided on the inner top wall of the cavity 14. A pressure plate 20 is connected inside the cavity 14. Both ends of the pressure plate 20 are in contact with the inner sidewall of the cavity 14 and are located at the output end of the cylinder B24. An oil-absorbing sponge 16 is connected inside the cavity 14 and is located at the bottom of the pressure plate 20. An oil guide pipe 12 is connected inside the concave frame A5, and one end of the oil guide pipe 12 is connected to the cavity 14. A bearing A11 is located inside the concave frame A5 on the surface of the rotating rod A25. The other end of the oil guide pipe 12 is in contact with the bearing A11.

[0032] An oil inlet pipe 15 is provided inside the concave frame A5 on one side of the cavity 14. The oil inlet pipe 15 passes through the concave frame A5 and is connected to a valve B22. The valve B22 is used to control whether oil enters the inside of the oil inlet pipe 15.

[0033] The concave frame B9 has a bearing B19 located on the surface of the rotating rod B26. The bearing B19 allows the rotating rod B26 to rotate more effectively.

[0034] The top of the lifting plate 4 is provided with a limit rod 2, which passes through the frame 1. The limit rod 2 is used to control the lifting of the lifting plate 4, and a spring 3 is sleeved on the surface of the limit rod 2.

[0035] The second V-shaped straightening wheel 8 has a flat straightening groove 21 on one side.

[0036] A valve A13 is connected to the surface of the oil guide pipe 12. The valve A13 is used to control whether oil enters the inside of the oil guide pipe 12, and can also control the flow rate.

[0037] Specifically, in use, firstly, lubricating oil is injected into the cavity 14 inside the concave frame A5 through the oil inlet pipe 15. After the injection is completed, the valve B22 is closed. At this time, the oil-absorbing sponge 16 will absorb the lubricating oil. Then, the deformed angle steel to be corrected is placed between the concave frame A5 and the concave frame B9, so that the part of the angle steel to be corrected is between the first V-shaped straightening wheel 7 and the second V-shaped straightening wheel 8, and between the flat straightening wheel 17 and the flat straightening groove 21.

[0038] When cylinder A6 is activated, its output pushes the lifting plate 4 downward. Since the limiting rod 2 passes through the frame 1 and is fitted with a spring 3, the spring 3 acts as a buffer and limit, allowing the lifting plate 4 to move smoothly downward. This causes the concave frame A5 and its internal components to move downward, bringing the first V-shaped straightening wheel 7 and the flat straightening wheel 17 into contact with the angle steel. Simultaneously, motors A10 and B18 are activated. Motor A10 drives the rotating rod A25 to rotate, thereby causing the first V-shaped straightening wheel 7 and the flat straightening wheel 17 to rotate. Motor B18 drives the rotating rod B26 to rotate, which in turn causes the second V-shaped straightening wheel 8 and the flat straightening groove 21 to rotate. During rotation, the first V-shaped straightening wheel 7 and the second V-shaped straightening wheel 8 use their V-shaped structures to compress and straighten the bent parts of the deformed angle steel, while the flat straightening wheel 17 and the flat straightening groove 21 straighten the flat parts of the angle steel. In this way, the deformed angle steel is gradually straightened into the required shape.

[0039] During the correction process, in order to reduce the friction between the rotating rod A25 and the bearing A11, lubrication is required. At this time, the cylinder B24 is activated, and the output end of the cylinder B24 pushes the pressure plate 20 downward. The pressure plate 20 compresses the oil-absorbing sponge 16. Under the action of pressure, the lubricating oil in the oil-absorbing sponge 16 flows through the oil guide pipe 12 to the surface of the rotating rod A25 and the bearing A11 to form lubrication. The flow rate of the lubricating oil can be adjusted by controlling the valve A13.

[0040] Motor A10, motor B18, cylinder A6, and cylinder B24 are all controlled by PLC controllers. PLC controllers are existing technology and will not be described in detail here.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
