Description

[0001] This application claims priority to Chinese Patent Application No. 202422558544.1, filed on October 23, 2024, entitled "A Straightening Device Applicable to Profiles of Different Sizes", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of profile processing technology, and in particular to a straightening device suitable for profiles of different sizes. Background Technology

[0003] As is well known, profiles are objects with a certain geometric shape made of iron or steel, or other materials with a certain strength and toughness, through processes such as rolling, extrusion, and casting. These materials have fixed external dimensions, a certain cross-sectional shape, and certain mechanical and physical properties; profiles vary in size, and their cross-sectional dimensions are mostly rectangular; in the production process, in order to ensure the straightness of the profiles, they often need to be straightened by a straightening machine.

[0004] For example, Chinese invention patent CN103691771B discloses an aluminum profile straightening device. The device includes a clamping mechanism for holding the aluminum profile and a driving mechanism for driving the clamping mechanism. The front end of the device also has an isolation mechanism to prevent direct contact between the user's hand and the clamping mechanism. The auxiliary straightening vehicle has the same structure as the main straightening vehicle. Its simple structure and ease of use allow for effective stretching and straightening of aluminum profiles to eliminate bending and twisting, while also eliminating uneven stress along the cross-sectional direction. It is highly efficient, provides good straightening results, and is suitable for widespread use.

[0005] However, the device straightens the profile by fixing and pulling the two ends of the profile. In order to ensure the smooth progress of the straightening operation, the clamps need to clamp the two ends of the profile, which can easily damage the two ends of the profile. In addition, the corresponding clamps need to be replaced for profiles of different sizes, which is not very applicable. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a straightening device suitable for profiles of different sizes, which can straighten profiles of different sizes, has a more reasonable structural layout, improves the straightening efficiency of profiles, and avoids damage to the ends of profiles.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a straightening device suitable for profiles of different sizes, comprising a ground rail, two first straightening mechanisms symmetrically arranged and slidably mounted on the ground rail, and a driver for providing power for the movement of the two first straightening mechanisms. The first straightening mechanism comprises a gantry frame, a horizontal straightening component mounted on the gantry frame, and a vertical straightening component.

[0008] The horizontal straightening assembly includes a lower clamping roller rotatably mounted on a gantry frame, a bearing seat slidably mounted on the gantry frame, an upper clamping roller rotatably mounted on the bearing seat, and a lifting drive cylinder that drives the bearing seat to slide up and down.

[0009] The vertical straightening assembly includes two swing frames hinged to the gantry and arranged symmetrically, side clamping rollers rotatably mounted on the swing frames, and a feed pusher 10 for driving the swing frames 8 to rotate. Both side clamping rollers are arranged perpendicular to the upper and lower clamping rollers.

[0010] The upper and lower clamping rollers are arranged vertically in parallel, while the two side clamping rollers are arranged horizontally in parallel.

[0011] Preferably, the driver includes a mounting base fixedly installed in the middle of the ground rail, two rollers rotatably installed on the two mounting bases, a first pull rope, a second pull rope, a synchronous and opposite-direction transmission component, and a drive motor that provides power for the rotation of one set of rollers. The middle part of the first pull rope is fixedly connected to the middle part of the upper set of rollers, and the two ends of the first pull rope are respectively fixedly connected to the gantry frames on the two first straightening mechanisms. Fixed pulleys are rotatably installed at both ends of the ground rail. The middle part of the second pull rope is fixedly connected to the lower set of rollers, and the two ends of the second pull rope pass over the two fixed pulleys and are fixedly connected to the gantry frames on the two first straightening mechanisms. The two rollers are connected by a synchronous and opposite-direction transmission component.

[0012] The preferred synchronous counter-rotating transmission component consists of two gears, which are fixedly connected to the two rollers respectively and mesh with each other; alternatively, other equivalent components that can achieve synchronous counter-rotating transmission of the two rollers, such as a synchronous counter-rotating transmission gearbox, can also be used.

[0013] Preferably, a support platform is fixedly mounted on the top of the mounting base, and the top surface of the support platform is tangent to the top surface of the lower clamping roller.

[0014] Preferably, it further includes a second straightening mechanism with the same structure as the first straightening mechanism, and the first and second straightening mechanisms are symmetrically arranged and fixedly connected to each other.

[0015] Preferably, it further includes an elastic reset connector, and the corresponding side clamping rollers on the first straightening mechanism and the second straightening mechanism are elastically connected by the elastic reset connector; further, the elastic reset connector is preferably a tension spring, and the two ends of the tension spring are respectively rotatably connected to the corresponding side clamping rollers.

[0016] The feed pusher is a cylinder or hydraulic cylinder fixedly installed on the gantry. After the piston rod of the feed pusher extends out, it contacts the side of the swing frame and pushes the swing frame to swing.

[0017] Preferably, the lower clamping roller and the upper clamping roller are inertially mounted on the gantry and the bearing seat, respectively, and the side clamping roller is inertially mounted on the swing frame; further, the lower clamping roller and the upper clamping roller are inertially connected to the gantry and the bearing seat through inertial bearings; the side clamping roller is inertially connected to the swing frame through inertial bearings; the inertial bearings are oil-damped bearings or the bearing rotation resistance is increased by filling or the like.

[0018] Preferably, the outer walls of the upper clamping roller, lower clamping roller, and side clamping roller are all provided with frosted texture; further, the outer walls of the upper clamping roller, lower clamping roller, and side clamping roller are all frosted to improve the friction between them and the outer wall of the profile.

[0019] Compared with the prior art, this utility model provides a straightening device suitable for profiles of different sizes, which has the following beneficial effects: In the initial state, the two first straightening mechanisms are located in the middle of the ground rail. The profile passes through the upper and lower clamping rollers and between the two side clamping rollers. The lifting drive cylinder is activated, causing the lifting drive cylinder to drive the bearing seat to move down until the upper and lower clamping rollers are in close contact with the top and bottom surfaces of the profile, respectively. The feed pusher pushes the swing frame to rotate until the two side clamping rollers are in close contact with the left and right side surfaces of the profile, respectively. The driver pulls the two first straightening mechanisms to move towards the two ends of the ground rail, and the first straightening mechanism achieves the pulling and straightening of the profile during the movement. Moreover, the spacing between the upper and lower clamping rollers and the spacing between the two side clamping rollers can be adjusted to straighten profiles of different sizes. The structural layout is more reasonable, improving the profile straightening efficiency while avoiding damage to the profile ends. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1

[0032] Please refer to Figure 1-3 A straightening device suitable for profiles of different sizes includes a ground rail 1, two first straightening mechanisms 2 symmetrically arranged and slidably mounted on the ground rail 1, and a driver that provides power for the movement of the two first straightening mechanisms 2.

[0033] See Figure 4-5The first straightening mechanism 2 includes a gantry frame 3, a horizontal straightening assembly mounted on the gantry frame 3, and a vertical straightening assembly. The horizontal straightening assembly includes a lower clamping roller 4 rotatably mounted on the gantry frame 3, a bearing seat 5 slidably mounted on the gantry frame 3, an upper clamping roller 6 rotatably mounted on the bearing seat 5, and a lifting drive cylinder 7 that drives the bearing seat 5 to slide up and down. The vertical straightening assembly includes two swing frames 8 hinged to the gantry frame 3 and symmetrically arranged, side clamping rollers 9 rotatably mounted on the swing frames 8, and a feed pusher 10, which drives the swing frames 8 to rotate. Both side clamping rollers 9 are arranged perpendicular to the upper clamping roller 6 and the lower clamping roller 4; furthermore, the upper clamping roller 6 and the lower clamping roller 4 are arranged vertically parallel, and the side clamping rollers 9 are arranged horizontally parallel.

[0034] Specifically, the feed pusher 10 is a cylinder or hydraulic cylinder fixedly mounted on the gantry 3. After the piston rod of the feed pusher 10 extends, it contacts the side of the swing frame 8 and pushes the swing frame 8 to swing. The piston rod of the feed pusher 10 restricts the swing frame 8 from swinging back, forcing the side clamping roller 9 to always clamp the profile. When the piston rod of the feed pusher 10 retracts, the swing frame 8 can drive the side clamping roller 9 to swing back. The feed pusher 10 can also be a limiting screw or other equivalent component that restricts the rotation of the swing frame 8.

[0035] In this embodiment, the lower clamping roller 4 and the upper clamping roller 6 are inertially mounted on the gantry frame 3 and the bearing seat 5, respectively, and the side clamping roller 9 is inertially mounted on the swing frame 8. Furthermore, the lower clamping roller 4 and the upper clamping roller 6 are inertially connected to the gantry frame 3 and the bearing seat 5 through inertial bearings; the side clamping roller 9 is inertially connected to the swing frame 8 through inertial bearings; the inertial bearings are oil-damped bearings or the bearing rotation resistance is increased by filling or the like.

[0036] The outer walls of the upper clamping roller 6, lower clamping roller 4, and side clamping roller 9 are all provided with a frosted texture (not shown in the figure). This frosted finish increases the friction between the rollers and the outer wall of the profile. The combination of the inertial bearings and the frosted texture on the outer wall of the side clamping roller 9 enhances the friction between the profile and the rollers, ensuring that each roller maintains a high frictional pull on the profile's outer wall while rotating, thus guaranteeing the effective straightening and drawing process of the profile.

[0037] Please refer to Figure 6 and Figure 7The drive unit includes a mounting base 11 fixedly installed in the middle of the ground rail 1, two rollers 12 rotatably mounted on the two mounting bases 11, a first pull rope 13, a second pull rope 14, a synchronous and opposite-direction transmission component 15, and a drive motor 16 that provides power for the rotation of one set of rollers 12. The middle part of the first pull rope 13 is fixedly connected to the middle part of the upper set of rollers 12, and the two ends of the first pull rope 13 are respectively fixedly connected to the gantry 3 on the two first straightening mechanisms 2. Fixed pulleys 17 are rotatably mounted at both ends of the ground rail 1. The middle part of the second pull rope 14 is fixedly connected to a set of bottom rollers 12. The two ends of the second pull rope 14 pass over two fixed pulleys 17 and are fixedly connected to the gantry 3 on the two first straightening mechanisms 2. The two rollers 12 are connected by synchronous opposite-direction transmission components 15. Furthermore, the synchronous opposite-direction transmission components 15 are preferably two gears, which are fixedly connected to the two rollers 12 respectively and mesh with each other. Alternatively, other equivalent components that can realize synchronous opposite-direction rotation transmission of the two rollers 12, such as synchronous opposite-direction transmission gearboxes, can also be used.

[0038] The straightening device for profiles of different sizes provided in this embodiment starts the drive motor 16, and the lower set of rotating rollers 12 winds up the second pull rope 14. The second pull rope 14 gradually wraps around the outer wall of the rotating roller 12. At the same time, after being driven by the synchronous opposite transmission component 15, the upper set of rotating rollers 12 synchronously reverses, so that the first pull rope 13 wrapped on the upper rotating roller 12 gradually disengages from the corresponding rotating roller 12, pulling the gantry 3 of the two first straightening mechanisms 2 in a direction away from each other, realizing synchronous driving of the two first straightening mechanisms 2. Similarly, it can also cause the two first straightening mechanisms 2 to reset synchronously. In this way, the profile can be repeatedly straightened, ensuring that the profile is subjected to balanced force during the straightening process, and improving the straightening effect and efficiency of the profile.

[0039] Example 2

[0040] The straightening device for profiles of different sizes provided in Example 1 has been further optimized, specifically, as follows: Figure 4-5 As shown, a support platform 18 is fixedly installed on the top of the mounting base 11, and the top surface of the support platform 18 is tangent to the top surface of the lower clamping roller 4. The straightening device for profiles of different sizes provided in this embodiment places the middle part of the profile on the top of the support platform 18. During the profile straightening process, it avoids the situation where the middle part of the profile is concave due to its own weight, and ensures that the profile is placed in a horizontal position during the straightening operation, thereby further ensuring the straightening accuracy of the profile.

[0041] Example 3

[0042] The straightening device for profiles of different sizes provided in Example 2 has been further optimized, specifically, as follows: Figure 1-6As shown, it also includes a second straightening mechanism 19 with the same structure as the first straightening mechanism 2. The first straightening mechanism 2 and the second straightening mechanism 19 are arranged symmetrically, and the gantry 3 of the first straightening mechanism 2 and the second straightening mechanism 19 are fixedly connected to each other.

[0043] It also includes an elastic reset connector 20, through which the corresponding side clamping rollers 9 on the first straightening mechanism 2 and the second straightening mechanism 19 are elastically connected. In this embodiment, the elastic reset connector 20 is preferably a tension spring, with its two ends rotatably connected to the corresponding side clamping rollers 9.

[0044] The straightening device provided in this embodiment, applicable to profiles of different sizes, allows for synchronous straightening of the profiles between the first straightening mechanism 2 and the second straightening mechanism 19 during the pulling and straightening process of the profiles. This straightens small bends on the profiles, further improving the straightening effect. When the feed pusher 10 disengages from the limit on the swing frame 8, under the action of the elastic reset connector 20, the two corresponding side clamping rollers 9 on the first straightening mechanism 2 and the second straightening mechanism 19 move closer to each other, while the two side clamping rollers 9 on the same straightening mechanism move further away from each other, achieving automatic reset of the side clamping rollers 9. This eliminates the need for manual intervention and other complex mechanical mechanisms, resulting in a simple structure that facilitates subsequent maintenance and repair.

[0045] The process of using the straightening device for different profiles provided by this utility model is as follows: The middle part of the profile is placed on the support platform 18, and the two ends of the profile pass through the upper clamping roller 6 and the lower clamping roller 4 on the first straightening mechanism 2 and the second straightening mechanism 19, and between the two side clamping rollers 9 respectively. The lifting drive cylinder 7 is started, so that the lifting drive cylinder 7 drives the bearing seat 5 to move down until the upper clamping roller 6 and the lower clamping roller 4 are in close contact with the top and bottom end surfaces of the profile respectively. The feed pusher 10 pushes the swing frame 8 to rotate until the two side clamping rollers 9 are in close contact with the left and right side end surfaces of the profile respectively. The driver pulls the two first straightening mechanisms 2 and the second straightening mechanism 19 to move towards the two ends of the ground rail 1 respectively. Then the driver drives the rotating roller 12 to rotate in the opposite direction, and the first straightening mechanism 2 and the second straightening mechanism 19 are reset. The first straightening mechanism 2 and the second straightening mechanism 19 achieve the pulling and straightening treatment of the profile during the movement of the first straightening mechanism 2 and the second straightening mechanism 19.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
