Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile processing, specifically an aluminum profile lifting and stretching auxiliary device. Background Technology

[0002] When straightening aluminum profiles in a straightening machine, to meet the requirements for supporting and conveying the profiles, a cylinder or hydraulic cylinder is typically used for lifting and lowering to feed the profiles into the clamps of the straightening machine. While this solution can meet the basic lifting and support functions to a certain extent, it is prone to insufficient adaptability when dealing with aluminum profiles of various specifications and shapes. This is mainly manifested in the fixed lifting stroke and limited adjustment precision, making it impossible to flexibly and accurately adjust the height and support different types of aluminum profiles.

[0003] However, when multiple sets of equipment are working simultaneously, it is difficult to achieve complete synchronization of the cylinders or hydraulic cylinders, resulting in uneven force on some aluminum profiles during flipping or lifting, causing slight bending or damage. Furthermore, when the aluminum profiles enter or leave the clamps of the stretching machine, the movement of the cylinders or hydraulic cylinders, without effective cushioning, is prone to generating large impacts. These instantaneous impacts can cause the aluminum profiles to vibrate or sway, thus affecting the straightening quality and surface quality.

[0004] With the increasingly widespread application of aluminum profiles in the industrial field, the demand for small-batch, multi-specification switching is constantly increasing, placing higher demands on the synchronization, precision, and adaptability of equipment. How to significantly improve the adaptability to different types of aluminum profiles while achieving aluminum profile flipping and lifting actions, and minimize surface damage during operation, has become a pressing technical problem in this field. Based on this, this utility model, combining cylinder flipping with a screw jack, emphasizes considerations for lifting precision and device synchronization. By enabling flexible fine-tuning during flipping and lifting, it provides safer and more reliable support and cushioning when aluminum profiles enter the clamp and exit the straightening machine. Utility Model Content

[0005] To address the problem of slight bending or damage to aluminum profiles due to uneven stress during flipping or lifting, this utility model provides an aluminum profile lifting and stretching auxiliary device.

[0006] This utility model is achieved through the following technical solution: an aluminum profile lifting and auxiliary stretching device, comprising a mounting base, a tilting cylinder, and a lifting device. The lifting device is mounted on the mounting base via a bearing mechanism. The lifting device includes a screw jack, a middle frame, a linear guide rail assembly, and a sliding frame. The middle frame is mounted on the bearing mechanism. One end of the tilting cylinder is fixed to the mounting base, and the other end of the tilting cylinder is connected to the middle frame. The sliding frame is mounted on the middle frame via the linear guide rail assembly. The lower part of the screw jack is mounted on the middle frame via a fixing plate, and the upper screw of the screw jack is connected to the sliding frame. This device enables stable lifting and smooth conveying of aluminum profiles during the stretching process of a straightening machine, improving overall production efficiency and reducing surface damage.

[0007] As a further improvement to the above technical solution, the tilting angle of the lifting device is 0-90 degrees. By flexibly adjusting the tilting angle, the lifting angle can be reasonably set according to the length and shape requirements of the aluminum profile, further improving the adaptability and safety of the working space.

[0008] As a further improvement to the above technical solution, a side fixing plate is also included. The side fixing plate is installed on the upper part of the mounting base and located on the outside of the lifting device. By adding an external fixing plate, additional stable support and protection can be provided for the device during lifting and tilting, avoiding interference or damage to the device components caused by external forces or debris.

[0009] As a further improvement to the above technical solution, the side fixing plate is welded to the mounting base. This welding method creates a robust whole between the side fixing plate and the mounting base, significantly enhancing the overall rigidity and durability of the device and ensuring stable operation even during long-term use.

[0010] As a further improvement to the above technical solution, a multi-turn absolute encoder is also included, which is installed on one side of the screw jack. By using a multi-turn absolute encoder, the number of rotations and angular displacement of the screw jack can be accurately monitored, providing reliable data support for precise control of the lifting position and effectively improving the level of automation.

[0011] As a further improvement to the above technical solution, the multi-turn absolute encoder is coaxially mounted with the drive shaft of the screw jack. This coaxial mounting structure allows for precise acquisition of real-time rotation information of the screw jack during operation, significantly reducing transmission errors and ensuring more accurate height positioning of the aluminum profile during straightening.

[0012] As a further improvement to the above technical solution, a motor guard plate is also included, which is installed on the intermediate frame and located at the top of the screw jack. By adding a motor guard plate to the top of the screw jack, the motor and related transmission components can be effectively protected, reducing interference or damage from the external environment to the core parts of the device, and further improving the safety and service life of the device.

[0013] As a further improvement to the above technical solution, a felt roller is also included, which is installed on the upper part of the sliding frame. By setting a felt roller on the sliding frame, the aluminum profile can be flexibly contacted and its surface can be cushioned during the lifting and lowering process, effectively reducing the risk of surface scratches caused by friction or collision and improving product quality.

[0014] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: By combining the tilting cylinder with the screw jack and using the bearing mechanism as the tilting fulcrum, the lifting device can be adjusted in angle within the range of 0-90 degrees, and precise height positioning can be achieved in conjunction with the screw jack. The tilting cylinder can provide stable and controllable power during a wide range of tilting movements, while the screw jack utilizes its high-precision transmission characteristics to keep the sliding frame stable during up and down movement and adapt to the clamping position requirements of different aluminum profiles. The cooperation between the intermediate frame and the linear guide rail assembly can ensure smooth movement even under tilting and lifting loads, avoiding jamming or shaking. Through this structural combination, on the one hand, it can flexibly adjust for aluminum profiles of different sizes and cross-sectional shapes within a wide range; on the other hand, it can significantly reduce the risk of surface damage and slight bending caused by synchronous deviation of the device, thereby achieving more stable lifting and placement movements, improving production efficiency and product quality, and providing a safer and more reliable operating space for subsequent straightening or transmission processes.

[0019] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] refer to Figs. 1-2As shown, this utility model discloses an aluminum profile lifting and stretching auxiliary device, including a mounting base 1, a tilting cylinder 3, and a lifting device. The lifting device is mounted on the mounting base 1 via a bearing mechanism 4. One end of the tilting cylinder 3 is fixed to the mounting base 1, and the other end is connected to the intermediate frame of the lifting device to drive the lifting device to tilt around the bearing mechanism 4. The lifting device includes a screw jack 7, an intermediate frame 9, a linear guide rail assembly 10, and a sliding frame 11. The intermediate frame 9 is mounted on the bearing mechanism 4, and the sliding frame 11 is mounted on the intermediate frame 9 via the linear guide rail assembly 10. The lower part of the screw jack 7 is mounted on the intermediate frame 9 via a fixing plate, and the upper part of the screw jack 7... The screw is connected to the sliding frame 11. In actual use, the lifting device is rotated around the bearing mechanism 4 by the tilting cylinder 3, and with the precise adjustment of the screw jack 7, the aluminum profile can be smoothly sent to the clamp of the stretching machine and clamped. Then the lifting device is tilted or lowered to cooperate with the straightening operation. After the aluminum profile is straightened, it is tilted or raised again to remove it from the clamp of the stretching machine and transferred to the next station. The height and angle can be flexibly adjusted according to the size and position requirements of different aluminum profiles, effectively avoiding surface damage caused by asynchrony or inaccurate positioning, and significantly improving production efficiency and operational safety. When it is necessary to straighten aluminum profiles of different lengths and cross-sectional shapes, the tilting cylinder 3 provides... The flipping action allows the aluminum profile to maintain a relatively stable posture during the lifting process. Simultaneously, the synchronous movement between the internal screw of the screw jack 7 and the sliding frame 11 ensures precise control of the lifting position. This provides the aluminum profile with a more suitable support angle and height before it enters the clamping machine, avoiding the asynchronous lifting phenomenon that occurs when multiple machines operate simultaneously, as seen with simple pneumatic or hydraulic cylinders. Once the aluminum profile is precisely fed into the clamping machine and successfully clamped, the lifting device can quickly flip or descend to a predetermined position, providing sufficient working space for the straightening process. After straightening, the lifting device returns to its original flipped or raised position, smoothly removing the aluminum profile from the clamp. The aluminum profile is then transferred to the next workstation or conveyor line, achieving a relatively continuous and automated production process. During this process, due to the high transmission precision of the screw jack 7 and the stable operation of the tilting cylinder 3, coupled with the low friction characteristics provided by the bearing mechanism 4, the relative friction and impact between the aluminum profile and the lifting device are greatly reduced when the device performs tilting or lifting operations. This not only reduces surface scratches but also prevents minor bending deformation caused by vibration or improper stress. In addition, since the intermediate frame 9 and the sliding frame 11 are connected by a linear guide rail assembly 10, the entire structure can still ensure smooth sliding and avoid jamming after being subjected to force, further improving the stability and safety of the aluminum profile when it is fed into or pushed out of the clamp.When producing small batches of aluminum profiles in rotation, this device can quickly adjust the lifting position and tilting angle by changing the settings of the screw jack 7 or by coordinating with the operating parameters of the tilting cylinder 3. This allows for efficient and low-damage straightening of the aluminum profiles regardless of their length, width, or cross-sectional shape. Throughout the process, the mounting base 1 provides stable support for the device, while the tilting cylinder 3 enables a wide range of angle adjustments. Combined with the fine-tuning of the screw jack 7 in the height dimension, this not only allows the aluminum profiles to easily adapt to the clamping position of the stretching machine but also significantly reduces damage to the surface of the aluminum profiles during straightening. The impact results in higher quality semi-finished products for subsequent processes. Therefore, this device can meet the straightening requirements of various types of aluminum profiles on the same production line, minimizing losses or damage caused by human error and equipment asynchrony. It significantly improves production efficiency and product yield. Furthermore, its relatively compact design requires little space when installed in a workshop or automated production line, facilitating maintenance and upkeep, and extending its service life. Overall, it is a flexible, precise, and durable aluminum profile lifting and stretching auxiliary device, offering significant advantages in applications requiring rapid flipping and fine-tuning of height before and after stretching.

[0021] The tilting angle of the lifting device can be adjusted within the range of 0 to 90 degrees. The tilting cylinder enables flexible rotation of the entire structure, providing smoother operating space for the aluminum profiles as they enter or exit the stretching machine clamps. During the tilting process, the device can select any tilting angle according to different needs, adapting to the specifications and conveying requirements of the aluminum profiles, effectively avoiding interference and damage caused by excessive or insufficient tilting. Simultaneously, driven by the tilting cylinder 3, the lifting device maintains a stable state and achieves precise positioning, providing reliable assurance for the straightening of the aluminum profiles and subsequent processes, thereby significantly improving production efficiency and safety.

[0022] It also includes a side fixing plate 2, which is installed on the upper part of the mounting base 1 and located on the outside of the lifting device. During operation, this side fixing plate effectively protects and supports the tilting and lifting structure, preventing component displacement or impact due to external interference or accidental contact during tilting. By setting the side fixing plate 2 on the upper part of the mounting base 1, the overall stability of the mechanism can be maintained while preventing debris and foreign objects from entering the moving area of ​​the lifting device, further reducing safety hazards in the production environment and extending the service life of the device, thereby ensuring the efficiency and reliability of the aluminum profile lifting and auxiliary stretching operation.

[0023] It also includes a multi-turn absolute encoder 8, which is installed on one side of the screw jack 7. Through effective cooperation with the transmission mechanism of the screw jack 7, it can accurately detect the lifting position and provide real-time feedback to the control system. This multi-turn absolute encoder 8 can record and monitor the angular changes of the screw jack 7 within multiple rotation ranges, ensuring precise control and repeatability of the lifting process, thereby further improving the automation and stability of the aluminum profile lifting and auxiliary stretching operation.

[0024] The multi-turn absolute encoder 8 is coaxially mounted with the drive shaft of the screw jack 7. This structural arrangement allows the angular displacement and rotation changes of the screw jack 7 during the lifting process to be accurately converted into electrical signals and fed back to the control system in real time. This provides a more precise basis for height control during the lifting and placement of aluminum profiles. Because the multi-turn absolute encoder 8 can record cumulative rotation angles exceeding the range of a single turn, it can still ensure positioning accuracy and effectively eliminate mechanical backlash or cumulative errors even in long-stroke or multi-lifting operation modes, providing a reliable guarantee for the automation and synchronization of the overall device.

[0025] It also includes a motor guard plate 5, which is installed on the intermediate frame 9 and located on the upper part of the screw jack 7. By setting the motor guard plate 5 on the intermediate frame 9, the screw jack 7 can effectively protect its motor and corresponding transmission structure when it is working, preventing splashes, dust or other foreign objects in the external environment from entering the device and affecting the transmission performance. It also reduces the risk of operators accidentally touching or scratching the device during production.

[0026] The system also includes a felt roller 6, which is mounted on the upper part of the sliding frame 11. When in contact with the aluminum profile, the felt roller 6 acts as a buffer and reduces friction, especially during the lifting or lowering of the aluminum profile. The elasticity and softness of the felt material effectively reduce the risk of impacts or scratches on the aluminum profile surface. Since the felt roller 6 moves together with the sliding frame 11, this structure can continuously provide good support and buffering for the aluminum profile during lifting or tilting. Furthermore, its rolling characteristics allow the aluminum profile to move smoothly along the roller surface, thereby further improving the overall operating efficiency and safety of the device.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
