Description

Technical Field

[0001] This invention relates to the field of aluminum alloy manufacturing technology, and more specifically, to a feeding device for an aluminum rod extrusion press. Background Technology

[0002] The feeding device of the aluminum rod extrusion press is a key piece of equipment to ensure that the aluminum rods enter the extrusion process efficiently and safely. Its design must meet the requirements of automation, precision and stability. The automated feeding device can achieve 24-hour continuous operation, reduce manual intervention and improve production efficiency.

[0003] Mechanical feeding devices typically consist of a hopper, a pushing mechanism, a support device, and a conveying device. The hopper stores aluminum bars to be processed and supports batch feeding. The pushing mechanism, driven by hydraulics or electricity, pushes the aluminum bars from the hopper layer by layer to the support device. The support device is equipped with a bar handling device that transports the aluminum bars one by one to the conveying device, which then transports the aluminum bars to the extrusion press inlet. Automated feeding devices consist of an integrated preheating box, a multi-stage feeding mechanism, and an intelligent control system. The preheating box preheats the aluminum bars to reduce temperature loss during extrusion and improve forming quality. The multi-stage feeding mechanism uses robotic arms or conveyor belts to automatically grab, position, and convey the aluminum bars. The intelligent control system monitors the position, temperature, and extrusion press status of the aluminum bars in real time and dynamically adjusts the feeding rhythm, making the aluminum alloy manufacturing feeding process automated and highly efficient. It is suitable for large-scale extrusion production lines. The automated device, through its enclosed design and safety sensors, avoids direct human contact with high-temperature aluminum bars and the extrusion press, reducing the risk of burns, crushing accidents, and other incidents.

[0004] Currently, existing feeding devices for aluminum rod extrusion presses typically consist of a robot and a conveying mechanism. The robot clamps and transfers the aluminum rods, which have been preheated in a slow furnace or a fast furnace, to a peeling machine or a conveying mechanism. The conveying mechanism then transports the aluminum rods into the extrusion press for processing. However, it is difficult for the robot to precisely adjust the gripping position of the aluminum rods, which can easily reduce the gripping accuracy and cause the transfer position of the aluminum rods to deviate, thus affecting the feeding accuracy. Therefore, this does not meet the current requirements. To address this, we propose a feeding device for aluminum rod extrusion presses. Summary of the Invention

[0005] This invention provides a feeding device for an aluminum rod extrusion press. This feeding device can precisely adjust the gripping position of the aluminum rod when the robot grips it, improving the gripping accuracy and preventing the transfer position of the aluminum rod from shifting, thereby improving the feeding accuracy of the aluminum rod. Therefore, it solves the problem mentioned in the background art that it is difficult to precisely adjust the gripping position of the aluminum rod when the robot grips it, which easily reduces the gripping accuracy of the aluminum rod and easily causes the transfer position of the aluminum rod to shift, thus easily affecting the feeding accuracy of the aluminum rod.

[0030] According to some embodiments of this disclosure, a feeding device for an aluminum rod extrusion press is provided, see reference. Figure 1 — Figure 8As shown, the feeding device for the aluminum bar extrusion press includes a robot 100, a conveyor track 110, and an aluminum bar support tray 120 slidably disposed on the side of the conveyor track 110. An adjusting block 121 is installed on the outside of the conveyor track 110, a guide rail 122 is provided on the side of the adjusting block 121, and a positioning pin 123 is slidably disposed on the side of the guide rail 122. A positioning hole 124 is opened on the side of the aluminum bar support tray 120 to cooperate with the positioning pin 123. A lifting cylinder 125 is installed on the outside of the adjusting block 121. The telescopic end of the lifting cylinder 125 is fixedly connected to the positioning pin 123, and the lifting cylinder 125 drives the positioning pin 123. The 23 rises, causing the positioning pin 123 to slide into the positioning hole 124. Through the cooperation of the positioning pin 123 and the positioning hole 124, the position of the aluminum rod support tray 120 is positioned, so that the aluminum rod can be accurately placed on the aluminum rod support tray 120. The aluminum rod support tray 120 slides on the conveying track 110, so that the aluminum rod support tray 120 carries the aluminum rod on it into the extruder, thereby conveying and feeding the aluminum rod. The aluminum rod support tray 120 is driven by a power mechanism to slide along the conveying track 110. This is a technical means well known to those skilled in the art and will not be described in detail here.

[0031] A fixed claw 130 is fixedly mounted on the end of the robot 100. A rotating shaft 140 is rotatably connected to the side of the fixed claw 130. A movable claw 150 is provided on the side of the fixed claw 130. Both ends of the rotating shaft 140 are fixedly connected to the middle of the movable claw 150. A force output cylinder 160 is fixedly mounted on the outside of the fixed claw 130. A connecting rod 170 is rotatably connected to the telescopic end of the force output cylinder 160. The end of the connecting rod 170 is rotatably connected to the end of the movable claw 150. A protective cylinder 171 is also fixedly mounted on the outside of the fixed claw 130. The telescopic end of the protective cylinder 171 is also rotatably connected to a connecting rod 170. The end of the rod 170 is also rotatably connected to the end of the movable claw 150. The rotation of the movable claw 150 is limited and protected by the protective cylinder 171 to prevent the movable claw 150 from loosening when the output cylinder 160 fails, thereby avoiding the danger of the aluminum rod falling when the robot 100 is gripping and transferring the aluminum rod. Adjustment plates 180 are slidably provided on both sides of the movable claw 150. The aluminum rod is gripped by the cooperation of the movable claw 150 and the fixed claw 130. During the gripping process, the gripping position of the aluminum rod is adjusted by the adjustment plates 180.

[0032] Both ends of the rotating shaft 140 are fitted with first bevel gears 190 with interference fit. A second bevel gear 191 is rotatably mounted on the outside of the movable claw 150. The first bevel gear 190 meshes with the second bevel gear 191. A winding shaft 192 is fixedly mounted in the middle of the second bevel gear 191. Slide rods 193 are fixedly mounted on the outside of the two adjusting plates 180. The ends of the slide rods 193 are slidably inserted into the side of the movable claw 150. The two adjusting plates 180 are symmetrically arranged on both sides of the movable claw 150. A first spring 194 is provided on the inside of the movable claw 150. One end of the first spring 194 is fixedly connected to the slide rod 193, and the other end of the first spring 194 is fixedly connected to the inner wall of the movable claw 150. In the initial state, the robot 100 has not gripped the aluminum rod. In the initial state, the two adjusting plates 180 are respectively away from the two sides of the movable claw 150, and the first spring 194 is in a stretched state.

[0033] A lever 195 is provided between the spool 192 and the slide bar 193. A traction rope 196 is wound around the outside of the spool 192. One end of the lever 195 is fixedly connected to the end of the traction rope 196, and the other end of the lever 195 is rotatably connected to the slide bar 193. The lever 195 includes an outer rod 1951 fixedly connected to the traction rope 196, an inner rod 1952 slidably inserted into the inner side of the outer rod 1951, and a second spring 1953 connected between the outer rod 1951 and the inner rod 1952. The end of the inner rod 1952 is rotatably connected to the middle of the slide bar 193. The second spring 1953 is located inside the outer rod 1951. One end of the second spring 1953 is fixedly connected to the inner wall of the outer rod 1951, and the other end of the second spring 1953 is fixedly connected to the end of the inner rod 1952. A support rod 200 is provided between the movable claw 150 and the lever 195. The support rod 200 provides a fulcrum for the rotation of the lever 195.

[0034] A first positioning component 210 is provided on the outside of the lever 195. The first positioning component 210 includes a first fixed clamp 211 rotatably mounted on the end of the support rod 200, a first movable clamp 212 slidably mounted on the side of the first fixed clamp 211, a first limiting rod 213 fixedly mounted on the outside of the first fixed clamp 211 and passing through the first movable clamp 212, and a first nut 214 threadedly connected to the end of the first limiting rod 213. A first limiting groove 215 is provided in the middle of the lever 195 to slide with the first limiting rod 213. The lever 195 is located between the first fixed clamp 211 and the first movable clamp 212, and the first limiting rod 213 is slidably inserted into the first limiting groove 215.

[0035] A second positioning component 220 is also provided on the outer side of the lever 195. The second positioning component 220 includes a second fixed clamp 221 slidably disposed on the side of the support rod 200, a second movable clamp 222 slidably disposed on the side of the second fixed clamp 221, a second limiting rod 223 slidably inserted into the side of the second fixed clamp 221 and passing through the second movable clamp 222, and a second nut 224 threadedly connected to the end of the second limiting rod 223. The movable claw 150 has a second limiting part in the middle that slides with the second limiting rod 223. The groove 225 and the support rod 200 are also provided with a third limiting groove 226 that slides with the second limiting rod 223. The movable claw 150 is located between the second fixed clamp 221 and the second movable clamp 222. The second limiting rod 223 is slidably inserted into the second limiting groove 225 and the third limiting groove 226. The second limiting rod 223 at the sliding insertion point with the second fixed clamp 221 and the sliding insertion point with the support rod 200 are both set as square rods to prevent the second fixed clamp 221 and the support rod 200 from rotating relative to each other.

[0036] With the above technical solution, when the feeding device for the aluminum rod extrusion machine provided in this disclosure is in use, firstly, the end of the robot 100 moves to the side of the aluminum rod to be clamped, so that the fixed claw 130 and the movable claw 150 are respectively located on both sides of the aluminum rod. The extension end of the output cylinder 160 extends outward, so that the extension end of the output cylinder 160 drives the upper end of the movable claw 150 to move outward through the connecting rod 170, so that the movable claw 150 rotates around the central pivot 140, thereby bringing the lower end of the movable claw 150 close to the fixed claw 130, so that the aluminum rod is clamped between the fixed claw 130 and the movable claw 150. Meanwhile, as the movable claw 150 rotates to grip the aluminum rod, the rotating shaft 140, which serves as the center of rotation, also rotates. The rotating shaft 140 drives the first bevel gear 190 to rotate. Through the meshing of the first bevel gear 190 and the second bevel gear 191, the second bevel gear 191 drives the winding shaft 192 to rotate synchronously. The rotating winding shaft 192 releases the traction rope 196 wound on it, relieving the tension of the traction rope 196 on the upper end of the lever 195. Since the first spring 194 is in a stretched state at this time, the rebound force of the first spring 194 causes the slide rod 193 to retract inward. This causes the lever 195 to drive the first positioning component 210, which is clamped in the middle of the lever 195, to rotate with the end of the support rod 200 as the pivot point. This causes the retracted slide rod 193 to drive the movable claw 150 on both sides. The adjusting plates 180 are brought closer together. During this process, the aluminum rod that is out of position can be pushed, thereby adjusting the position of the aluminum rod so that the fixed claw 130 and the movable claw 150 can accurately grip the position of the aluminum rod. Then, the robot 100 moves the gripped aluminum rod, and the output cylinder 160 drives the movable claw 150 to rotate and reset, releasing the grip of the fixed claw 130 and the movable claw 150 on the aluminum rod. The aluminum rod can then be placed on the aluminum rod support tray 120. The rotating shaft 140, through the meshing of the first bevel gear 190 and the second bevel gear 191, drives the winding shaft 192 to rewind the traction rope 196. The traction rope 196 pulls the lever 195 to reset, and also resets the adjusting plate 180, thus completing the aluminum rod loading operation. Furthermore, loosening the first nut 214 allows the first positioning component 210 to slide along the lever 195, and loosening the second nut 224 allows the second positioning component 2210 to slide along the movable claw 150 and the support rod 200. Adjusting the support point of the support rod 200 on the lever 195 changes the fulcrum of the lever 195's rotation. When the length of the released traction rope 196 is constant, the closer the fulcrum of the lever 195's rotation is to the traction rope 196, the greater the distance the adjusting plate 180 can move. Similarly, the closer the fulcrum of the lever 195's rotation is to the slide rod 193, the smaller the distance the adjusting plate 180 can move. This allows the adjusting plate 180 to precisely adjust the position of aluminum bars of different lengths, enhancing the adaptability and practicality of the device for aluminum bars of different sizes. In summary, by adding a robot 100 between the existing slow-heating furnace, fast-heating furnace, aluminum rod peeling machine, and extruder, the robot 100, through the coordinated use of its fixed claw 130 and movable claw 150, can grip and transfer aluminum rods, achieving the goal of flexibly selecting different feeding routes. Furthermore, by changing the moving distance of the adjusting plate 180, the position of the adjusting plate 180 can be adjusted for aluminum rods of different sizes. This allows the slow-heating furnace, fast-heating furnace, and aluminum rod peeling machine to share a single extruder. At the same time, by adjusting the position of the aluminum rod through the adjusting plate 180, the accuracy of gripping the aluminum rod is improved, preventing the gripping and transfer position of the aluminum rod from shifting, thereby improving the feeding accuracy of the aluminum rod.

[0037] It should be noted that when lever 195 rotates, both the upper and lower ends of lever 195 exhibit an arc-shaped movement trajectory. The upper end of lever 195 is connected to the winding shaft 192 via a traction rope 196. The flexibility of the traction rope 196 ensures that the movement of the upper end of lever 195 is unimpeded. Meanwhile, an inner rod 1952 is slidably inserted into the lower end of lever 195. The extension and retraction of the inner rod 1952 allows the slide rod 193 to maintain horizontal movement, thereby enabling the slide rod 193 to drive the adjusting plate 180 to move horizontally.

[0038] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0039] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0040] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
