Description

Technical Field

[0001] This utility model relates to the field of aluminum rod processing technology, and in particular to a feeding system for aluminum rod processing. Background Technology

[0002] Before processing aluminum rods, they need to be uniformly heated in an aluminum rod heating furnace. The aluminum rod heating furnace is an industrial equipment used to heat aluminum rods to change their properties, optimize their microstructure, and improve their processing performance.

[0003] To improve the processing efficiency of aluminum bars, a bar-turning and feeding mechanism for aluminum bar heating furnaces has been developed (publication number CN213811682U). A feeding rack, a turning roller, and a feeding rack are sequentially arranged at the front end of the heating furnace feed inlet. Both the feeding rack and the feeding rack are inclined. The turning roller has several arc-shaped grooves spaced along its circumference. Driven by a motor, the turning roller rotates around its axis and uses the arc-shaped grooves to pick up the aluminum bars on the feeding rack, causing the aluminum bars to turn over with the turning roller onto the feeding rack. The feeding rack then guides the aluminum bars into the heating furnace, achieving rapid feeding of aluminum bars.

[0004] In existing aluminum rod heating furnaces, the aluminum rods are flipped by the flipping rollers and then rolled onto the feeding rack under the influence of gravity. During the rolling process, the aluminum rods are prone to collisions with the feeding rack, resulting in localized stress concentration on the surface of the aluminum rods. This can easily lead to crack sources during subsequent heating, causing defects such as cracking during the processing of the aluminum rods and affecting their machinability. In addition, the arc-shaped groove on the flipping rollers has a fixed size, which can only realize the picking and flipping of aluminum rods of a fixed size, resulting in poor overall adaptability. Utility Model Content

[0005] To address the technical problem in existing aluminum rod feeding devices described above, where the aluminum rod rolls and falls onto the feeding rack under gravity after being flipped by the turning roller, it is prone to collision with the feeding rack, resulting in localized stress concentration on the surface of the aluminum rod. This can easily lead to cracks during subsequent heating, affecting the machinability of the aluminum rod. Therefore, this invention provides a feeding system for aluminum rod processing.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides a feeding system for aluminum rod processing, including a feeding rack, a flipping claw, and a feeding rack arranged in sequence. Both the feeding rack and the feeding rack are inclined downwards. A positioning mechanism is installed at the end of the feeding rack near the flipping claw. The flipping claw is rotatably mounted on the frame and is connected to a flipping drive unit on the frame. The flipping claw includes a picking part and a feeding part fixedly connected. The picking part is close to the feeding rack and is used to lift the aluminum rod on the feeding rack and guide it to the feeding part. The upper surface of the feeding part is inclined towards the feeding rack. A flexible overlapping part is fixedly provided at one end of the feeding part. The feeding part is connected to the feeding rack through the flexible overlapping part. The picking part picks up the aluminum rod by lifting it up, which can adapt to aluminum rods of different sizes. The setting of the feeding part and the flexible overlapping part can realize the guiding of the aluminum rod, so that the aluminum rod automatically rolls to the feeding rack and no longer rolls off, avoiding collision damage to the aluminum rod.

[0008] Preferably, the side of the material taking part that contacts the aluminum rod is provided with a first arc-shaped section, which is convex and is used to contact and push the aluminum rod on the feeding rack when the material taking part is flipped, so as to ensure the smoothness of the flipping of the material taking part; the upper surface of the material taking part is provided with a second arc-shaped section, which is concave and provides more stable support for the aluminum rod during the material taking process. It can accommodate the raised aluminum rod, guide the aluminum rod to smoothly transition to the feeding part, improve the accuracy and stability of feeding, and also play a role in reducing the rolling speed of the aluminum rod, so as to reduce the speed of the aluminum rod when it rolls onto the feeding part, thereby reducing the impact of collision on the aluminum rod.

[0009] Preferably, a transition section is provided between the first arc segment and the second arc segment. The transition section has a rounded chamfer structure, which reduces the resistance and impact on the aluminum rod, reduces the risk of scratches or damage on the surface of the aluminum rod, and ensures the surface quality of the aluminum rod.

[0010] Preferably, a buffer layer is fixedly provided on the upper surface of both the picking section and the feeding section, which effectively reduces the impact force of the aluminum rod on the picking section and the feeding section during the picking and feeding process, further protects the surface of the aluminum rod from being scratched or damaged, and also reduces the noise and vibration generated during the operation of the equipment, thus extending the service life of the equipment.

[0011] Preferably, the feeding rack has several bolt holes spaced along its length. The positioning mechanism is detachably installed on the feeding rack by bolts. The position of the positioning mechanism can be flexibly adjusted according to the different specifications of the aluminum bars and the actual processing requirements to improve the positioning accuracy of the aluminum bars. It can effectively adjust the relative position between the outer circle of aluminum bars of different sizes and the picking part, thereby meeting the picking requirements of aluminum bars of different sizes, enhancing the versatility and adaptability of the feeding system, and meeting diverse aluminum bar processing tasks.

[0012] Preferably, the positioning mechanism includes a mounting base installed on the feeding rack. A buffer positioning block is detachably mounted on the mounting base. The end of the buffer positioning block near the aluminum rod extends outward from the mounting base. The mounting base is threaded with a tightening bolt, which is used to tighten and limit the buffer positioning block. The buffer positioning block can play a dual role of buffering and positioning the aluminum rod, preventing the aluminum rod from rolling randomly on the feeding rack. The buffer positioning block can also help improve the positioning accuracy of the aluminum rod. The detachable connection between the positioning mechanism and the feeding rack allows for quick coarse adjustment of the positioning mechanism's position. The adjustment of the buffer positioning block's position is not limited by the position of the threaded hole. The buffer positioning block can achieve fine adjustment of its position to improve positioning accuracy. It can effectively adjust the relative position of the outer circle of aluminum rods of different sizes with the first arc segment of the picking part, thereby meeting the picking requirements of aluminum rods of different sizes.

[0013] Preferably, the end of the buffer positioning block that contacts the aluminum rod is arc-shaped, which can better fit the outer surface of the aluminum rod, increase the contact area, improve the positioning accuracy, and effectively buffer the impact force of the aluminum rod during the contact process to avoid damage to the surface of the aluminum rod.

[0014] Preferably, at least one flipping claw is provided, which can be adjusted according to actual needs to improve the stability of aluminum bar lifting, flipping and guiding.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are:

[0016] 1. The feeding section is connected to the feeding rack via a flexible overlap section, and the picking section picks up the aluminum rod by lifting it up. It can adapt to aluminum rods of different sizes. One end of the feeding section is fixedly equipped with a flexible overlap section, and the feeding section is connected to the feeding rack via the flexible overlap section, which can realize the guiding of the aluminum rod, so that the aluminum rod is automatically rolled onto the feeding rack and no longer rolls down, avoiding collision damage to the aluminum rod.

[0017] 2. The upper surface of the material handling section is provided with a second arc-shaped section, which is concave. This provides more stable support for the aluminum rod during the material handling process, can accommodate the raised aluminum rod, guide the aluminum rod smoothly to the feeding section, improve the accuracy and stability of the feeding, and also reduces the rolling speed of the aluminum rod, thereby reducing the speed at which the aluminum rod rolls onto the feeding section and thus reducing the impact on the aluminum rod.

[0018] 3. The positioning mechanism is equipped with a buffer positioning block and is positioned by a tightening bolt. The detachable connection between the positioning mechanism and the feeding rack enables rapid coarse adjustment of the positioning mechanism position. The adjustment of the buffer positioning block position is not limited by the position of the threaded hole. The buffer positioning block can achieve fine adjustment of the position to improve positioning accuracy. It can effectively adjust the relative position of the outer circle of aluminum bars of different sizes and the first arc segment of the feeding part, thereby meeting the feeding requirements of aluminum bars of different sizes.

[0025] 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.

[0026] In a typical embodiment of this utility model, such as Figure 1As shown, a feeding system for aluminum rod processing is proposed, including: a frame 1, a feeding rack 2, a flipping claw 3, a flipping drive unit 4, and a feeding rack 6. The frame 1 is fixedly installed on the ground and close to the feeding port of the heating furnace 7. The feeding rack 2 is fixedly installed on the frame 1 at an angle downward for placing aluminum rods. The flipping claw 3 is located on the side of the feeding rack 2 close to the heating furnace 7 and is rotatably mounted on the frame 1. One end of the flipping drive unit 4 is rotatably connected to the flipping claw 3, and the other end of the flipping drive unit 4 is rotatably connected to the frame 1. The flipping drive unit 4 is used to drive the flipping claw 3 to flip, thereby realizing the flipping of aluminum rods. The feeding rack 6 is installed at an angle downward inside the furnace chamber of the heating furnace 7. The receiving end of the feeding rack 6 (i.e., the highest end of the feeding rack 6) extends outward from the heating furnace and is close to but does not contact the flipping claw 3, so as to receive the aluminum rods delivered by the flipping claw 3 and transport them into the furnace chamber of the heating furnace 7.

[0027] Specifically, two opposing bearing seats are fixedly provided on the frame 1, and a rotating shaft 5 is rotatably connected between the two bearing seats. The axis of the rotating shaft 5 is parallel to the axis of the aluminum rod on the feeding rack 2. At least one flipping claw 3 is fixedly provided on the rotating shaft 5, and an ear is also fixedly provided on the rotating shaft 5. The ear is hinged to the telescopic end of the flipping drive unit 4. The other end of the flipping drive unit 4 is hinged to the frame 1. The flipping drive unit 4 drives the flipping claw 3 to rotate around the axis through the rotating shaft 5 to achieve flipping. In this embodiment, the flipping drive unit 4 is a flipping oil cylinder.

[0028] like Figure 2 As shown, the flipping claw 3 includes a picking part 8 and a feeding part 9, which are integrally formed. The picking part 8 is close to the unloading rack 2 for picking up aluminum bars from the unloading rack 2. The feeding part 9 is close to the feeding rack 6. The aluminum bars picked up by the picking part 8 can be rolled along the feeding part 9 to the feeding rack 6, avoiding the aluminum bars from falling directly onto the feeding rack 6 under the action of gravity, thereby effectively avoiding collision damage between the surface of the aluminum bars and the feeding rack 6.

[0029] It is understandable that the feeding rack 2 is a frame structure, and the end of the feeding rack 2 near the flipping claw 3 is an open end. The open end of the feeding rack 2 is not equipped with a crossbeam to avoid obstructing the flipping action of the flipping claw 3.

[0030] Specifically, the picking section 8 has a fan-shaped structure, and the upper surface of the feeding section 9 is inclined towards the feeding rack 6. The upper surface of the picking section 8 is higher than the feeding section 9. The picking section 8 is used to remove aluminum bars from the unloading rack 2 and guide them to the feeding section 9. The feeding section 9 is used to transport the aluminum bars to the feeding rack 6. When the picking section 8 flips upward to pick up materials, when the picking section 8 moves to the end position, the bottom of the picking section 8 is lower than the lowest point of the upper surface of the unloading rack 2, thus avoiding the aluminum bars from obstructing the resetting of the picking section 8. When the picking section 8 flips downward to reset, when the picking section 8 moves to the end position, the top of the picking section 8 is not higher than the lowest point of the upper surface of the unloading rack 2, preventing obstruction of the replenishment of aluminum bars and facilitating the subsequent picking of aluminum bars.

[0031] A flexible overlapping part 12 is fixedly provided at one end of the feeding part 9 near the feeding rack 6. The flexible overlapping part 12 is supported by rubber material and is fixedly connected to the feeding part 9 by bolts. When the feeding part 9 flips downward to feed material (at this time, the picking part 8 flips upward to the end position), the flexible overlapping part 12 at the end of the feeding part 9 overlaps on the feeding rack 6. The aluminum rod rolls down along the feeding part 9 and moves along the flexible overlapping part 12 to the feeding rack 6, preventing the aluminum rod from rolling down and colliding with the feeding rack 6 and causing damage. In addition, the setting of the flexible overlapping part 12 can also avoid hard collision damage between the feeding part 9 and the feeding rack 6.

[0032] The length of the flexible overlap 12 should not be too long. For example, in actual design, the gap between the feeding part 9 and the feeding rack 6 can be set to 1cm, and the flexible overlap 12 can be set to a length of not less than 1cm. The feeding part 9 will not have a hard collision with the feeding rack 6, and the problem of insufficient support caused by the flexible overlap 12 being too long can also be avoided. It is understood that the specific length of the flexible overlap 12 can be determined according to the actual design requirements, and no further restrictions are imposed here.

[0033] In this embodiment, a buffer layer 18 is fixedly provided on the upper surface of both the material taking part 8 and the material feeding part 9. The buffer layer 18 is a rubber layer, which avoids hard collision between the aluminum rod and the material taking part 8 and the material feeding part 9, and effectively protects the integrity of the outer surface of the aluminum rod.

[0034] like Figure 2 As shown, the material taking part 8 includes a first arc-shaped section 10 and a second arc-shaped section 11. The first arc-shaped section 10 is convex and located on the side surface of the material taking part 8. It is used to contact and push the aluminum rod on the feeding rack 2 when the material taking part 8 is flipped, so as to ensure the smoothness of the flipping of the material taking part 8. The second arc-shaped section 11 is concave and located on the upper surface of the material taking part 8. It serves to reduce the rolling speed of the aluminum rod, so as to reduce the speed of the aluminum rod when it is rolled onto the feeding part 9, thereby reducing the impact of the collision on the aluminum rod.

[0035] A transition section 13 is provided between the first arc segment 10 and the second arc segment 11. The transition section 13 has a rounded chamfer structure, which serves as a transition connection to eliminate sharp corners and prevent the sharp corner structure from scratching the surface of the aluminum rod during material handling.

[0036] like Figure 1 As shown, a positioning mechanism 14 is provided at the lowest end of the feeding rack 2. The positioning mechanism 14 is detachably connected to the feeding rack 2 to block and position the aluminum rod, facilitating the material handling operation of the flipping claw 3. Several bolt holes 19 are provided at intervals along the length of the feeding rack 2. The positioning mechanism 14 is connected to the bolt holes 19 by bolts to fix the position of the positioning mechanism 14. The setting of several bolt holes 19 makes the position of the positioning mechanism 14 adjustable, so that the positioning position of the aluminum rod can be adjusted according to the size of the aluminum rod, so that the material handling part 8 can adapt to the material handling needs of aluminum rods of different sizes and specifications.

[0037] like Figure 3 As shown, the positioning mechanism 14 includes a mounting base 15, a buffer positioning block 16, and a tightening bolt 17. The mounting base 15 has a U-shaped structure and is detachably mounted on the feeding rack 2 by bolts. The buffer positioning block 16 is made of rubber and is detachably mounted on the mounting base 15. A threaded hole is provided on the side wall of the mounting base 15. The threaded hole penetrates the side wall of the mounting base 15 and contains internal threads. The tightening bolt 17 is threadedly connected to the threaded hole. By tightening the tightening bolt 17, the buffer positioning block 16 is tightened and limited.

[0038] In other embodiments, a top plate may be fixedly provided at the end of the tightening bolt 17 to increase the contact area between the tightening bolt 17 and the buffer positioning block 16 and reduce the damage of the tightening bolt 17 to the buffer positioning block 16.

[0039] The buffer positioning block 16 is provided to assist in the positioning of aluminum bars. The detachable connection between the positioning mechanism 14 and the feeding rack 2 enables quick coarse adjustment of the position of the positioning mechanism 14. The adjustment of the position of the buffer positioning block 16 is not limited by the position of the threaded hole. The buffer positioning block 16 can achieve fine adjustment of the position to improve the positioning accuracy. It can effectively adjust the relative position of the outer circle of aluminum bars of different sizes and the first arc segment 10 of the feeding part 8, thereby meeting the feeding requirements of aluminum bars of different sizes.

[0040] The end of the buffer positioning block 16 that contacts the aluminum rod is arc-shaped to facilitate the positioning of the aluminum rod. The arc-shaped section of the buffer positioning block 16 extends outward from the mounting base 15 to achieve flexible contact with the aluminum rod and avoid collision damage to the aluminum rod.

[0041] The specific working principle is as follows:

[0042] Adjust the overall position of the positioning mechanism 14 and the position of the buffer positioning block 16 on the mounting base 15 according to the size of the aluminum rod. Place the aluminum rod on the feeding rack 2 so that the aluminum rod rolls along the feeding rack 2 towards the flipping claw 3. The buffer positioning block 16 is used to position the aluminum rod. When the aluminum rod needs to be heated, the flipping drive unit 4 is activated, and the picking part 8 moves upward to pick up the material. One aluminum rod on the feeding rack 2 falls into the second arc segment 11, while the first arc segment 10 contacts the aluminum rod on the feeding rack 2 to temporarily restrict the position of the aluminum rod on the feeding rack 2. The material taking part 8 continues to move upward to the end position. At this time, the feeding part 9 moves downward to the end position, and the flexible overlapping part 12 overlaps on the feeding rack 6. The aluminum rod in the second arc segment 11 is rolled along the feeding part 9 and the flexible overlapping part 12 to the feeding rack 6 under the action of gravity, and then conveyed to the heating furnace 7 through the feeding rack 6. The flipping drive unit 4 is reset, the feeding part 9 moves upward, and at the same time the material taking part 8 moves downward until the material taking part 8 moves down to the bottom of the feeding rack 2. The aluminum rod on the feeding rack 2 rolls under the action of gravity and contacts the buffer positioning block 16.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. 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. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
