Description

Technical Field

[0001] This utility model relates to the technical field of feeding auxiliary devices for homogenizing furnaces, and in particular to a mechanism for preventing aluminum rod wear in homogenizing furnaces. Background Technology

[0002] In the production of aluminum profiles, aluminum rods are used as raw materials. Homogenizing furnaces, through specific heating, heat preservation and cooling processes, can effectively eliminate the internal stress of aluminum rods, making the internal structure of aluminum rods more uniform and reducing component segregation.

[0003] In small aluminum rod homogenizing furnaces, aluminum rods are fed in one by one for homogenization. After the aluminum rods are manually placed into the feeding platform, workers need to manually push the aluminum rods to move them into the homogenizing furnace. During the process of manually pushing the aluminum rods into the homogenizing furnace, a certain amount of force needs to be applied, and the pushing direction is mostly vertical, which will generate relatively strong friction between the aluminum rods and the surface of the feeding platform and the track.

[0004] During subsequent processing and use, worn areas are prone to becoming stress concentration points, which can lead to defects such as cracks, further affecting the quality and performance of aluminum profile products. Utility Model Content

[0005] In order to address the above-mentioned existing technical issues, this utility model provides a solution in the field of a feeding auxiliary device for a homogenizing furnace.

[0006] The technical solution of this utility model is achieved through the following scheme: a mechanism for preventing aluminum rod wear in a homogenizing furnace, comprising a feeding assembly, a slow feeding device, a transmission roller conveyor and a support platform, wherein the feeding assembly is provided with a horizontal unloading receiving platform, the discharge port of the feeding assembly is connected to the slow feeding device, the slow feeding device is connected to the homogenizing furnace through the transmission roller conveyor, and both the feeding assembly and the slow feeding device are located on the support platform; The feeding assembly includes a support cover and a feeding port. The horizontal feeding receiving platform is rotatably installed inside the support cover and is located below the axis of the feeding port.

[0007] Through the above technical solutions, the horizontal unloading receiving platform and the slow-speed feeding device work together to avoid the feeding method of violent collision of aluminum bars, reduce the wear between aluminum bars and equipment parts, and reduce the defect rate caused by wear. The horizontal unloading receiving platform ensures that the aluminum bars fall smoothly from the loading port onto the horizontal unloading receiving platform, which provides a guarantee for the subsequent stable delivery of aluminum bars to the slow-speed feeding device, ensuring a stable and reliable feeding process and reducing equipment failures and production interruptions caused by unstable feeding.

[0008] Preferably, the horizontal unloading receiving platform includes a left receiving platform and a right receiving platform, which are arranged opposite to each other and have the same structure.

[0009] Through the above technical solutions, the split-type components are set up opposite each other and have the same structure to share the weight of the aluminum rod. This makes the aluminum rod more evenly stressed during the feeding process, avoiding problems such as damage to the receiving platform or slippage of the aluminum rod caused by excessive stress on one side, and improving the stability and safety of the entire feeding process.

[0010] Preferably, the right receiving platform includes a bearing arc plate, several servo cylinders, a hinge, and a support rod. The bearing arc plate is hung inside the support housing by the support rod. The non-hanging end of the bearing arc plate is fitted with a hinge. The telescopic ends of several servo cylinders are hinged to the hinge. The servo cylinders are detachably mounted on the outer surface of the support housing.

[0011] Through the above technical solutions, the extension and retraction length of the servo electric cylinder is precisely controlled, thereby driving the bearing arc plate to rotate around the hanging point, realizing precise adjustment of the aluminum rod feeding angle, flexibly changing the downward angle of the aluminum rod, ensuring that the aluminum rod enters the arc groove of the feeding wheel at the optimal angle, reducing the shaking and jumping of the aluminum rod, reducing the collision and wear between the aluminum rod and the equipment, and improving the stability and accuracy of feeding.

[0012] Preferably, the feeding assembly further includes a servo motor and a feeding wheel. The feeding wheel is rotatably installed inside the support cover. The output end of the servo motor passes through the support cover and is connected to the feeding wheel. The horizontal feeding receiving platform is located between the feeding port axis and the feeding wheel.

[0013] Through the above technical solutions, the rotation speed and interval of the feeding wheel are precisely controlled by the servo motor, so that the aluminum bars can be fed in sequence in a rhythmic manner, avoiding uneven feeding intervals and ensuring the stability and orderliness of the feeding process.

[0014] Preferably, the slow feeding device includes a support shell, a slow adjustment component, and a buffer pad. The support shell has a feed through hole that communicates with the discharge port of the feeding component. The slow adjustment component is inclinedly arranged on the side of the inner cavity of the support shell near the feed through hole. The buffer pad is laid on the other side of the support shell. A transmission roller is installed at the bottom of the support shell, and a roller motor is connected to the transmission roller.

[0015] Preferably, the deceleration adjustment assembly includes a deceleration plate, several buffer springs and dampers, the deceleration plate is obliquely mounted on the support shell, and the deceleration plate is connected to the support shell through several buffer springs and dampers.

[0016] Through the above technical solutions, the speed of the aluminum rod is gradually reduced by the combined action of the inclined slow-speed adjustment component and the laid buffer pads, avoiding the aluminum rod from impacting at too high a speed, ensuring a smooth and orderly feeding process, and reducing the risk of wear and damage to the aluminum rod.

[0017] In summary, this utility model has the following beneficial effects: 1. This utility model avoids the feeding method of violent collision of aluminum bars by working together with the horizontal unloading receiving platform and the slow feeding device, thereby reducing the wear between the aluminum bars and equipment parts and reducing the defect rate caused by wear. The horizontal unloading receiving platform ensures that the aluminum bars can fall smoothly onto the horizontal unloading receiving platform when they fall from the loading port, which provides a guarantee for the subsequent stable delivery of the aluminum bars to the slow feeding device, ensuring that the feeding process is stable and reliable, and reducing equipment failures and production interruptions caused by unstable feeding.

[0018] 2. The separate, oppositely arranged, and identical structures share the weight of the aluminum rod, making the force on the aluminum rod more even during the feeding process. This avoids problems such as damage to the receiving platform or slippage of the aluminum rod caused by excessive force on one side, thus improving the stability and safety of the entire feeding process.

[0019] 3. The extension and retraction length is precisely controlled by a servo electric cylinder, which drives the bearing arc plate to rotate around the hanging point, thereby achieving precise adjustment of the aluminum bar feeding angle and flexibly changing the downward angle of the aluminum bar. This ensures that the aluminum bar enters the arc groove of the feeding wheel at the optimal angle, reducing the shaking and jumping of the aluminum bar, reducing the collision and wear between the aluminum bar and the equipment, and improving the stability and accuracy of feeding.

[0020] 4. The rotation speed and interval of the feeding wheel are precisely controlled by a servo motor, so that the aluminum bars can be fed in sequence in a rhythmic manner, avoiding uneven feeding intervals and ensuring the stability and orderliness of the feeding process.

[0021] 5. The tilted slow-motion adjustment component and the laid buffer pads work together to gradually slow down the movement speed of the aluminum rod, preventing the aluminum rod from impacting at too high a speed, ensuring a smooth and orderly feeding process, and reducing the risk of wear and damage to the aluminum rod.

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] A mechanism for preventing aluminum rod wear in a homogenizing furnace, such as Figures 1-5 As shown, the device includes a feeding assembly 1, a slow feeding device 3, a transmission roller conveyor 4, and a support platform 5. The feeding assembly 1 has a horizontal unloading receiving platform 2. The discharge port of the feeding assembly 1 is connected to the slow feeding device 3. The slow feeding device 3 is connected to the homogenizing furnace 6 through the transmission roller conveyor 4. Both the feeding assembly 1 and the slow feeding device 3 are located on the support platform 5. The entire mechanism occupies a relatively small area and has a more compact structure. It realizes the function of aluminum rods from initial feeding to slow entry into the homogenizing furnace 6 within a limited space. One side of the feeding assembly 1 abuts against the slow feeding device 3, and the abutment has a discharge port and a corresponding feed through hole.

[0027] The feeding assembly 1 includes a support cover 11 and a feeding port 14. The horizontal feeding receiving platform 2 is rotatably installed inside the support cover 11. The horizontal feeding receiving platform 2 is located below the axis of the feeding port 14. The horizontal feeding receiving platform 2 is semi-circular in shape, and its bottom surface is on the same plane as the bottom surface of the feeding port 14 to ensure that there is no height difference. When the semi-circular concave arc surface is opened to release the material, it can naturally guide the aluminum rod to the center position, preparing it for the next step of the rotary conveyor.

[0028] like Figure 2As shown, the feeding assembly 1 also includes a servo motor 12 and a feeding wheel 13. The feeding wheel 13 is rotatably installed inside the support cover 11. The output end of the servo motor 12 passes through the support cover 11 and is connected to the feeding wheel 13. The horizontal feeding receiving platform 2 is located between the axis of the feeding port 14 and the feeding wheel 13. The feeding wheel 13 has four arc-shaped grooves arranged in a ninety-degree circular array to accommodate the aluminum bars placed down by the horizontal feeding receiving platform 2. Every time the feeding wheel 13 rotates 90 degrees, a station will reach the bottom of the receiving platform to pick up the material. Only one aluminum bar is picked up at a time, realizing a single, intermittent feeding rhythm. The arc-shaped groove is equipped with a protective skin to prevent hard contact between metals from scratching or crushing the surface of the aluminum bar. The aluminum bar rolls out smoothly from the discharge port of the support cover 11 and enters the slow feeding device 3.

[0029] like Figure 2 and Figure 3 As shown, the horizontal unloading receiving platform 2 includes a left receiving platform and a right receiving platform. The left and right receiving platforms are arranged opposite each other. The left and right receiving platforms have the same structure. The left and right receiving platforms are relatively unfolded to unload or close the material, so as to evenly distribute the stress and form a double-lobed movable receiving platform.

[0030] The right support platform includes a bearing arc plate 21, several servo cylinders 22, hinges 23, and support rods 24. The bearing arc plate 21 is suspended inside the support housing 11 via the support rods 24. The hinges 23 are installed on the convex surface of the non-suspended end of the bearing arc plate 21. The telescopic ends of the several servo cylinders 22 are hinged to the hinges 23. The servo cylinders 22 are detachably installed on the outer surface of the support housing 11. There are two servo cylinders 22, which are respectively located at both ends of the support housing 11. The telescopic ends penetrate the support housing 11 and pass through the bearing arc plate 21. The hinges 23 at both ends are hinged to each other to provide stable support and control for the bearing arc plate 21. The arc-shaped inner surface of the bearing arc plate 21 is used to receive the aluminum rod and guide it. The support rod 24 serves as the upper suspension point of the bearing arc plate 21, allowing the bearing arc plate 21 to move within a certain range instead of being rigidly fixed. Together with the servo electric cylinder 22, they form a movable fan-shaped unfolding structure. The hinge 23 is installed on the end face away from the support rod 24, which is the lower support point of the bearing arc plate 21. There are also two hinges 23.

[0031] When the two servo cylinders 22 extend synchronously, they push the hinge 23, causing the left and right bearing arc plates 21 to rotate upward and close with their top support rods 24 as the axis, forming a complete semi-circular bearing surface; when the servo cylinders 22 retract synchronously, they pull the hinge 23, causing the bearing arc plates 21 to rotate downward and open, thereby releasing the aluminum rod into the feeding wheel 13 below.

[0032] like Figure 4 and Figure 5As shown, the slow feeding device 3 includes a support shell 31, a slow adjustment component 32, and a buffer pad 33. The support shell 31 has a feed through hole that communicates with the discharge port of the feeding component 1. The slow adjustment component 32 is inclinedly arranged on the side of the inner cavity of the support shell 31 near the feed through hole. The buffer pad 33 is laid on the other side of the support shell 31. A transmission roller conveyor 4 is installed at the bottom of the support shell 31. The transmission roller conveyor 4 is connected to a roller conveyor motor 7. When the aluminum rod moves to the end of the support shell 31 under the action of the slow adjustment component 32, the buffer pad 33 can further absorb the remaining kinetic energy of the aluminum rod and play a final buffering role.

[0033] The deceleration adjustment assembly 32 includes a deceleration plate 321, several buffer springs 322, and a damper 323. The deceleration plate 321 is obliquely mounted on the support shell 31. The deceleration plate 321 is connected to the support shell 31 through several buffer springs 322 and dampers 323. The deceleration plate 321 is supported by multiple hinges and multiple buffer springs 322 and dampers 323, forming an oblique guide, giving the deceleration plate 321 a limited degree of vertical freedom of movement, and the buffer springs 322 and dampers 323 can also effectively... The impact and vibration generated during the movement of the aluminum rod are dispersed, making the movement of the aluminum rod more stable, reducing the friction and collision between the aluminum rod and the equipment, reducing the wear and internal damage of the aluminum rod surface, and causing the aluminum rod to roll to the buffer pad 33. The aluminum rod moves downward at the end of the buffer pad 33 and the deceleration plate 321, pressing the deceleration plate 321 until it reaches a distance sufficient for the aluminum rod to pass between the end of the deceleration plate 321 and the buffer pad 33. At this time, the deceleration plate 321 rebounds, and the aluminum rod falls smoothly onto the transmission roller 4.

[0034] The cushioning pad 33 ensures that the aluminum rod will not bounce violently or deviate from its direction, further absorbing the last bit of kinetic energy as the aluminum rod passes through the gap.

[0035] Horizontal rolling conveyors have less friction than vertical pushing conveyors. Less friction reduces friction between the aluminum rod surface and the equipment, reducing surface scratches and wear caused by friction, thus better protecting the surface quality of the aluminum rod and ensuring that the aluminum rod remains in good condition when entering subsequent processing steps.

[0036] The entire mechanism is externally controlled by a control cabinet. The circuit and communication connections adopt conventional connection methods in existing technology. The control cabinet uses PLC communication control to control start and stop, which will not be described in detail here. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Working principle: The aluminum rod enters the support cover 11 vertically through the feeding port 14 and is received by the horizontal unloading receiving platform 2. The four servo electric cylinders 22 retract, causing the left and right receiving platforms to separate. The aluminum rod then falls into the arc groove in the unloading roller 13, which is driven to rotate by the servo motor 12. Finally, the aluminum rod rolls horizontally from the discharge port into the slow feeding device 3. Then, it is damped and buffered by the slow adjustment component 32 in the slow feeding device 3. Finally, it slides onto the buffer pad 33 on the other side and rolls downward, pressing the end of the slow adjustment component 32 until the entire aluminum rod slides flat onto the transmission roller 4. The slow adjustment component 32 makes room for rebound, and finally the aluminum rod is conveyed to the homogenizing furnace 6 through the transmission roller 4.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
