Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy extrusion, and in particular to a device which can greatly improve the surface quality of aluminum alloy extruded profiles. Background Art

[0002] For a long time, the entire aluminum alloy extrusion industry in the world has faced a common difficulty. In the initial stage of extrusion with a new die, the profile surface is very good. As the extrusion volume increases, a layer of aluminum oxide particles will slowly accumulate on the outer end face of the die working belt. The aluminum oxide particles come from the surface of the high-temperature aluminum profile that has just been extruded. After the extruded profile comes out of the die working belt, some aluminum oxide particles fall off and stick to the end face of the die working belt. As time goes by, the amount of accumulated aluminum oxide increases, and the height gradually becomes flush with the height of the die working belt. The high-temperature profile coming out of the working belt will be scratched by the aluminum oxide accumulated flush with the die working belt. The hardness of aluminum oxide particles is very high, second only to diamond, which causes wire drawing marks on the surface of the aluminum profile.

[0003] Part of the accumulated alumina particles are adhered and carried away by the high-temperature aluminum profiles just taken out of the work, forming granular defects on the surface of the aluminum profiles. As the number of extrusions increases, the amount of alumina accumulated on the die end face increases, and the wire drawing phenomenon on the profile surface becomes more serious, resulting in a serious deterioration of the profile surface quality. When the surface wire drawing depth and amount exceed a certain limit, a new die can only be replaced to start a new round of extrusion;

[0004] The replaced mold needs to be corroded with NA (OH) solution to corrode the residual aluminum in the mold cavity. The waste liquid generated by the corrosion is very difficult to handle, which increases the burden on the environment and generates a lot of processing costs. Each time the mold is used to rot the waste aluminum, it needs to be manually polished, which is time-consuming and labor-intensive, and also produces dust that affects the health of the mold-casting workers. After each mold is replaced, the first section of bar extrusion requires material traction, which leads to material waste. Each mold replacement takes about half an hour, resulting in a decrease in machine utilization and a waste of energy and labor. Wiredrawing and granular defects have long been a chronic disease that has plagued the entire aluminum extrusion industry. Alloys of different grades and shapes will have this problem.

[0005] In this regard, China applied for patent number: CN102000711B, which discloses an extrusion tool, including an extrusion die support and a large scissors. The extrusion die support is provided with an inclined surface inclined relative to the large scissors on one end close to the large scissors, and an angle is formed between the inclined surface and the end face close to the large scissors; an adjustment gasket is provided between the guide rod of the large scissors and the blade connection. The present invention adjusts the shearing residue through the inclined surface of the extrusion die support and the large scissors adjustment gasket to achieve the existence of residues without residual residues on the die end face. In the process of shearing residues, due to the adjustment of the inclined surface of the extrusion die support and the large scissors adjustment gasket and the change of the shearing position, the gaps and sizes caused by some mechanism designs and wear of the extruder are overcome, and no residual residues are left on the end surface of the extrusion die during shearing. The problem of mold blockage, product scrapping, "large cap" caused by the failure of the extrusion cylinder to be locked, and the large scissors being stuck by the residual residues is solved. The present invention also discloses an extruder with the above-mentioned extrusion tool.

[0006] The entire industry has been constantly improving through measures such as mold optimization design, temperature optimization design, material optimization, process optimization, mold online cooling, and mold outlet inert gas protection, but the effects are not very obvious. Basically, the surface quality problem is solved by replacing the mold, which has caused huge energy waste, low production efficiency, and waste liquid from rotten molds has affected the environment. We are eager to find a new method that can solve the surface defects of aluminum alloy extruded profiles such as wiredrawing and particles caused by the accumulation of alumina particles, and greatly improve the surface quality of aluminum alloy extruded profiles. The entire industry has been constantly exploring for so many years, hoping to make a breakthrough, but there has been no breakthrough. Therefore, it has become an urgent problem to be solved for us to improve and improve the above-mentioned problems. Summary of the invention

When in use, at the end of each extrusion, the second scissors body and the first scissors body are moved a certain amount along the end surfaces of the first extrusion die and the second extrusion die to the surface of the extruded aluminum profile body, the second scissors body and the first scissors body are precisely fitted to the outer end surfaces of the first extrusion die and the second extrusion die, and the residue on the first extrusion die is A small amount of alumina particles on the end faces of the die and the second extrusion die are squeezed by the second scissors body and the first scissors body to the surface of the high-temperature extruded aluminum profile body and pressed into the aluminum profile. Then the second scissors body and the first scissors body withdraw and start extrusion. At this time, the alumina on the end faces of the first extrusion die and the second extrusion die has been taken away by the extruded aluminum profile body. The outer end faces of the first extrusion die and the second extrusion die are smooth, and the surface quality of the extruded profile will no longer be scratched by the alumina accumulated on the end faces of the first extrusion die and the second extrusion die. The surface quality of the profile is smooth. According to the process settings, when the machine is shut down, the aluminum profile close to the outlet ends of the first extrusion die and the second extrusion die is cut off and scrapped, so the alumina on the end faces of the first extrusion die and the second extrusion die is squeezed to the surface of the aluminum profile. The surface is cut off, which will not affect the surface quality and yield rate of normal production of aluminum alloy profiles. It solves the historical industry problem that aluminum alloy extruded profiles must be frequently changed to solve the defects of extruded profile wire drawing and particle quality due to the accumulation of alumina particles on the outer end surface of the die. This design can greatly improve the surface quality of hot extruded aluminum profiles, improve the production efficiency of the extruder, reduce the labor intensity of workers, greatly alleviate the adverse effects of waste liquid discharge on the environment, and save the cost of rotten molds, filling the gap in this technical field in China. The present invention utilizes the characteristics of high-temperature aluminum alloy profiles and high-temperature alumina particles that are easy to adhere to each other, and the high-temperature alumina particles on the end surfaces of the first extrusion die and the second extrusion die are sheared and pressed into the high-temperature aluminum through the second scissors body and the first scissors body. On the surface of the alloy profile, high-temperature alumina particles and high-temperature aluminum alloy profiles adhere to each other, and the alumina particles are carried away by the aluminum alloy profile, removing the alumina particles accumulated on the outer end faces of the first extrusion die and the second extrusion die, eliminating the surface drawing and particles of the profile caused by the alumina accumulation on the outer end faces of the extrusion profile die, greatly improving the surface quality of the aluminum alloy extruded profile, inventing high-temperature resistant imitation scissors that imitate the shape of extruded aluminum profiles, using the process window in which the machine needs to be stopped to change the bar after each section of the bar is extruded, to cut off the alumina particles accumulated on the end face of the aluminum alloy extrusion profile die, eliminating the surface drawing and particles of the extruded aluminum profile caused by the alumina accumulation on the end faces of the first extrusion die and the second extrusion die, and designing a special high-temperature resistant release agent mechanism for automatic spraying.A partition film is formed on the outer end surfaces of the second scissor body, the second electric push rod, the first extrusion die and the second extrusion die, which greatly reduces the adhesion between the aluminum oxide particles and the scissor surface and reduces the difficulty of separating the aluminum oxide particles and the scissors. A special high-temperature resistant lubricant spraying mechanism is designed to ensure the normal and effective operation of the shearing mechanism under high temperature conditions and achieve the designed shearing effect.

[0021] 2. The device, which can greatly improve the surface quality of aluminum alloy extruded profiles, comprises a connecting plate, a support frame, a motor body, a transmission mechanism, a first conveying roller, a second conveying roller, a stabilizing plate, a support block, a rotating shaft, a first bevel gear, a second bevel gear, a mounting rod, a rotating disk, a stabilizing block and a connecting frame. When in use, the support frame can be first connected via the connecting plate, and then the motor body is started, and the transmission mechanism can be driven to rotate via the motor body, and then the transmission mechanism can drive the first conveying roller and the second conveying roller to rotate, and the extruded aluminum profile body can be assisted to slide by the rotating first and second conveying rollers, and the extrusion discharging effect of the entire extruded aluminum profile body is better, and then the second conveying roller and the first conveying roller can be stably supported by the stabilizing plate and the support block, and the overall supporting effect is better, and then the rotating shaft is driven to rotate by the first conveying roller, and then the rotating The moving shaft will drive the first bevel gear to rotate. Due to the meshing between the first bevel gear and the second bevel gear, the second bevel gear will drive the mounting rod to rotate. Then the mounting rod will drive the rotating disk to rotate. Then the rotating disk will drive the rotating column to rotate. Then the rotating column will drive the rotating ring and the movable plate to move back and forth on the left and right sides. The movable plate can drive the impact rubber ball to move back and forth on the left and right sides. The impact rubber ball is driven to move by the movable plate, so that the impact rubber ball will hit the outer surface of the extruded aluminum profile body. Therefore, some impurities on the surface of the extruded aluminum profile body can be knocked off. The overall shedding effect is good. The impurities can be processed simultaneously while the extruded aluminum profile body is being conveyed. Then the second bevel gear can be limited by the stabilizing block. Then the position of the stabilizing block and the limiting side plate is limited by the connecting frame. The overall operating effect is good, which reflects the functionality of the design.

[0034] The second electric push rod 12 is installed on the left side surface of the first extruder wall panel 1, and the second scissors body 14 is installed on the left side surface of the second electric push rod 12. The outer surface of the second electric push rod 12 is provided with a second limiting cylinder 13, and the second limiting cylinder 13 is installed on the front surface of the first extrusion mold 3. The front surfaces of the first extruder wall panel 1 and the second extruder wall panel 7 are both installed with an inclined plate 15, and a demoulding agent tube 16 is installed on the back of the inclined plate 15. A connecting block 17 is installed on the back of the demoulding agent tube 16, and a lubricant tube 18 is installed on the back of the connecting block 17. The right side surfaces of the demoulding agent tube 16 and the lubricant tube 18 are both installed with a spray rack 19. The first scissors body 11 and the second scissors body 14 are designed and installed on the first extrusion mold 3 and the second The outer end face of the extrusion die 6, the scissors mouth and the outer end faces of the first extrusion die 3 and the second extrusion die 6 are precisely fitted to complete the shearing function. The first scissors body 11 and the second scissors body 14 are composed of two or more pieces. The first scissors body 11 and the second scissors body 14 surround the surface of the extruded profile. Scissors of different numbers are designed according to different cross-sectional shapes. A scissors movement track is designed. The scissors run along the track. The gap between the scissors shearing surface and the outer end face of the mold can be adjusted to ensure the shearing effect. The first limit cylinder 10 is also made of special high-temperature resistant and wear-resistant materials to ensure that the track will not deform and reduce performance in a high temperature environment of 600 degrees, ensuring that the gap between the scissors and the outer end face of the mold will not change, thereby ensuring the shearing effect of the scissors. The scissors are installed on the first In the limiting cylinder 10, the first limiting cylinder 10 plays the role of fixing the movement trajectory of the scissors, ensuring that the scissors and the end faces of the first extrusion die 3 and the second extrusion die 6 are closely fitted, thereby ensuring the shearing effect. The scissors are made of high temperature resistant materials to ensure that the quality and performance of the scissors will not decrease in a high temperature environment of 600 degrees for a long time. In order to ensure that every point around the outer end face of the mold can be cut cleanly, a certain overlap part needs to be designed between adjacent scissors. In order to ensure that the overlapped parts of the scissors do not interfere with each other during shearing, a sequence of scissors is designed. Scissors with overlapped parts can be designed not to cut at the same time. The program controls the pushing sequence of the scissors. When the scissors with interfering parts leave the surface of the aluminum alloy profile, the other scissors starts to start shearing. Each piece of scissors has a separate pushing mechanism. The first scissors The body 11 is connected to the first electric push rod 9, the thrust size and stroke of the first electric push rod 9 can be adjusted, the first electric push rod 9 communicates with the extruder, after each section of the bar is extruded, the extruder sends a command to the first electric push rod 9, the first electric push rod 9 pushes the scissors back and forth along the fixed track to complete the shearing of the aluminum oxide particles adhered to the outer end surface of the extrusion die, an automatic release agent spraying mechanism that can communicate with the press is installed on the outside of the scissors, and the release agent tube 16 communicates with the extruder. After each shearing, the extruder sends information to the release agent tube 16, and the release agent is evenly sprayed on the surface of the scissors and the outer end surfaces of the first extrusion die 3 and the second extrusion die 6 to ensure that the aluminum oxide particles will not adhere to the surface of the scissors when the scissors are shearing the aluminum oxide particles on the outer end surface of the extrusion die.Improve the shearing effect of the scissors. The alumina particles can be completely and quickly detached from the surface of the scissors. The detached particles are pressed into the high-temperature aluminum alloy profile and adhere to the surface of the high-temperature aluminum alloy profile, and are taken away by the aluminum profile when the extrusion is restarted. According to the design, each time the machine is stopped, the aluminum profile near the extrusion die is to be cut off and scrapped as process waste, so the section of the aluminum profile pressed with the alumina particles is scrapped as process waste. The alumina particles pressed into the surface of the aluminum profile do not affect the surface quality and yield rate. The release agent is designed to be a special release agent for high-temperature resistant aluminum alloys. When it is sprayed on the end face of the high-temperature extrusion profile die and the blade of the scissors, a thin film is formed to separate the alumina particles and The aluminum sticking on the outer end surface of the mold and the scissors mouth forms sufficient demoulding ability to ensure that after each shearing, the outer end surface of the scissors and the extrusion mold is smooth, which also ensures that the aluminum alloy extruded profile surface will not be brushed or granular due to the accumulation of aluminum oxide on the outer end surface of the extrusion mold. On the outside of the scissors guide rail, an automatic spray lubricant tube 18 that can communicate with the press is installed. After each extrusion, before the first electric push rod 9 starts to move, the lubricant tube 18 receives a signal from the extruder and starts spraying lubricant. A layer of high-temperature resistant lubricant is sprayed on the scissors fixed rail and the scissors surface to ensure the flexible movement of the scissors. The rail lubricant uses a special high-temperature resistant lubricant that can ensure that the aluminum profile is smooth. It still has excellent lubrication ability in the high temperature environment at the exit of the extrusion die, ensuring that the scissors can cut smoothly every time. At the end of each extrusion, the second scissors body 14 and the first scissors body 11 are used to move a certain amount along the end surfaces of the first extrusion die 3 and the second extrusion die 6 to the surface of the extruded aluminum profile body 41. The second scissors body 14 and the first scissors body 11 are precisely fitted with the outer end surfaces of the first extrusion die 3 and the second extrusion die 6. A small amount of aluminum oxide particles remaining on the end surfaces of the first extrusion die 3 and the second extrusion die 6 are squeezed by the second scissors body 14 and the first scissors body 11 to the surface of the high-temperature extruded aluminum profile body 41 and pressed into the aluminum profile The second scissors body 14 and the first scissors body 11 are then withdrawn and extrusion begins. At this time, the aluminum oxide on the end faces of the first extrusion die 3 and the second extrusion die 6 has been taken away by the extruded aluminum profile body 41. The outer end faces of the first extrusion die 3 and the second extrusion die 6 are smooth, and the surface quality of the extruded profile will no longer be scratched by the aluminum oxide accumulated on the end faces of the first extrusion die 3 and the second extrusion die 6. The surface quality of the profile is smooth. According to the process setting, when the machine is stopped, the aluminum profile near the outlet ends of the first extrusion die 3 and the second extrusion die 6 is cut off and scrapped. Therefore, the aluminum oxide on the end faces of the first extrusion die 3 and the second extrusion die 6 is squeezed to the surface of the aluminum profile and is cut.

[0035] Working principle: When the staff uses the device, first connect the device to an external power supply to provide power support for the device. At the end of each extrusion, the second scissors body 14 and the first scissors body 11 are used to move a certain amount along the end surfaces of the first extrusion die 3 and the second extrusion die 6 toward the surface of the extruded aluminum profile body 41. The second scissors body 14 and the first scissors body 11 are precisely fitted to the outer end surfaces of the first extrusion die 3 and the second extrusion die 6. A small amount of aluminum oxide particles remaining on the end surfaces of the first extrusion die 3 and the second extrusion die 6 are squeezed by the second scissors body 14 and the first scissors body 11 to the surface of the high-temperature extruded aluminum profile body 41 and pressed into the aluminum profile. Then the second scissors body 14 and the first scissors body 11 are withdrawn to start extrusion. At this time, the aluminum oxide on the end faces of the first extrusion die 3 and the second extrusion die 6 has been taken away by the extruded aluminum profile body 41, and the outer end faces of the first extrusion die 3 and the second extrusion die 6 are smooth. The surface quality of the extruded profile will no longer be scratched by the aluminum oxide accumulated on the end faces of the first extrusion die 3 and the second extrusion die 6. The surface quality of the profile is smooth. According to the process setting, when the machine is shut down, the aluminum profile near the outlet ends of the first extrusion die 3 and the second extrusion die 6 is cut off and scrapped. Therefore, the aluminum oxide on the end faces of the first extrusion die 3 and the second extrusion die 6 is squeezed onto the surface of the aluminum profile. The support frame 21 can be connected through the connecting plate 20, and then the motor body 22 is started, and the conveying mechanism 23 can be driven to rotate through the motor body 22, and then the conveying mechanism 23 The first conveyor roller 24 and the second conveyor roller 25 are driven to rotate, and the extruded aluminum profile body 41 can be assisted to slide by the rotating first conveyor roller 24 and the second conveyor roller 25, and the extrusion discharging effect of the overall extruded aluminum profile body 41 is better. Then, the second conveyor roller 25 and the first conveyor roller 24 can be stably supported by the stabilizing plate 26 and the supporting block 27, and the overall supporting effect is better. Then, the first conveyor roller 24 drives the rotating shaft 28 to rotate, and then the rotating shaft 28 drives the first bevel gear 29 to rotate. Since the first bevel gear 29 is meshed with the second bevel gear 30, the second bevel gear 30 drives the mounting rod 31 to rotate, and then the mounting rod 31 drives the rotating disk 32 to rotate, and then the rotating disk 32 The rotating column 35 will be driven to rotate, and then the rotating column 35 will drive the rotating ring 36 and the movable plate 37 to move back and forth on the left and right sides, so that the impact rubber ball 40 can be driven to reciprocate on the left and right sides through the movable plate 37, and the impact rubber ball 40 is driven to move through the movable plate 37, so that the impact rubber ball 40 will hit the outer surface of the extruded aluminum profile body 41, so that some impurities on the surface of the extruded aluminum profile body 41 can be knocked off, and the overall shedding effect is good, and the impurities of the extruded aluminum profile body 41 can be processed simultaneously while conveying the extruded aluminum profile body 41, and then the second bevel gear 30 can be limited by the stabilizing block 33, and then the position of the stabilizing block 33 and the limiting side plate 39 is limited by the connecting frame 34. The above is all the working principles of the present invention.
