Description

Technical Field

[0001] The invention relates to the technical field of aluminum rod processing, in particular to an aluminum rod forming device and an extrusion component and an extrusion method thereof. Background Art

[0002] Aluminum rod forming is a pressure processing method that applies extrusion force to one end of the aluminum rod segment to form the aluminum rod segment through the die hole. The aluminum rod segment needs to be treated with high temperature before extrusion to reduce the hardness of the aluminum rod segment, thereby improving the plasticity of the aluminum rod segment, so that the aluminum rod segment can reduce the friction between the die and the extrusion resistance during the extrusion process, making the aluminum rod processing smoother.

[0003] A Chinese patent with application number 202311201838.2 discloses an aluminum billet extrusion molding device, including an extrusion die, an extrusion mechanism, a power mechanism and a vacuum mechanism, wherein the extrusion mechanism is fixedly installed inside the extrusion die, the power mechanism is fixedly installed at one end of the extrusion mechanism, and the vacuum mechanism is fixedly installed at the other end of the molding chamber.

[0004] Chinese patent with announcement number CN111729941B discloses an extrusion die and conveying device for preventing tail shrinkage, including a conveying unit, a stepping unit, a rotating unit, and a scraping unit; the stepping unit is arranged at one end of the conveying unit, the rotating unit is arranged in the stepping unit, and the scraping unit is arranged in the stepping unit.

[0005] The above-mentioned extrusion processing equipment cannot accurately position and detect the aluminum rod segment before extrusion processing, resulting in the non-straight aluminum rod segment being bent and deformed due to uneven force during extrusion processing. Dust and impurities exist on the surface of the aluminum rod segment, which may cause the aluminum rod segment to get stuck during the extrusion process.

[0006] In addition, since the aluminum rod has a higher plasticity after heating, the aluminum rod segment will deform when subjected to extrusion pressure, causing a section of the aluminum rod segment to bulge and increase its diameter, or causing a section of the aluminum rod segment to bend, affecting the normal extrusion of the aluminum rod segment.

[0050] Specifically, the guide assembly 6 includes a third sliding plate 601, a support tube 602 is provided at the bottom of the third sliding plate 601, a movable groove 603 is opened on the inner side of the support tube 602, an elastic member 604 is provided on the inner wall of the movable groove 603, an inner end of the elastic member 604 is provided with an inner panel 605, and a plurality of inner panels 605 are spliced ​​together to form a cylinder, a pressure sensor 6041 is provided between the elastic member 604 and the inner panel 605, and the inner panel 605 is supported by the elastic member 604 to form a cylindrical structure, and the inner diameter of the cylindrical structure is matched with the diameter of the aluminum rod.

[0051] Specifically, a multi-axis translation mechanism 301 is provided on the supporting plate 3, and the multi-axis translation mechanism 301 includes three groups of driving components. The tops of the first sliding plate 401, the second sliding plate 501 and the third sliding plate 601 are respectively fixedly connected to the movable ends of the three groups of driving components. The power source of the driving components is preferably a linear motor, and the scraping component 4, the limiting component 5 and the guide component 6 are respectively controlled to move horizontally by the three linear motors.

[0052] When in use, the heated aluminum rod segment is first guided to the ingot feeding mechanism 11 through the ingot feeding mechanism. At this time, the scraping component 4 and the limiting component 5 are located on the side close to the die hole seat 1, and the guiding component 6 is located on the side close to the extrusion rod 2011. The heated aluminum rod segment is sent to the position corresponding to the extrusion rod 2011 by lifting the ingot feeding mechanism 11. Then, the multi-axis translation mechanism 301 first drives the scraping component 4 and the limiting component 5 to move toward the aluminum rod segment, so that one end of the aluminum rod segment is connected to the straight cylinder 407, and then drives the guiding component 6 to move toward the aluminum rod segment, so that the other end of the aluminum rod segment is connected to the cylinder composed of multiple inner panels 605. In this process, the aluminum rod segment is manually observed to see if there are obvious defects, and the aluminum rod segment is manually checked based on whether the two ends of the aluminum rod segment can be connected to the straight cylinder 407. 07 and the cylinder are connected to determine whether the aluminum rod end is straight. Moreover, after the aluminum rod segment is connected to the cylinder, if the inner puzzle plate 605 of the aluminum rod segment is squeezed and shrinks inward, the pressure sensor 6041 will detect that the aluminum rod segment is still offset. At this time, the multi-axis translation mechanism 301 drives the scraping component 4, the limit component 5 and the guide component 6 to move away from the aluminum rod segment, so that the two ends of the aluminum rod segment are respectively withdrawn from the straight tube 407 and the cylinder, and the ingot feeding mechanism 11 re-loads a new straight aluminum rod segment. By detecting whether the aluminum rod segment is straight, it is ensured that the aluminum rod segment extruded by the aluminum rod forming equipment is straight, so that the aluminum rod segment is subjected to more uniform force during extrusion, thereby avoiding production defects of the aluminum rod due to uneven force during extrusion when the aluminum rod segment is not straight.

[0053] After the two ends of the straight aluminum rod segment are butted with the straight cylinder 407 and the cylinder, the main cylinder 201 and the first side cylinder 202 drive the main cylinder support 2 and the extrusion rod 2011 to move toward the die hole seat 1, and continuously transport the aluminum rod segment into the straight cylinder 407. In the process of continuously transporting the aluminum rod segment into the die hole seat 1 through the straight cylinder 407, two balls 507 provide rolling support for the aluminum rod segment when the aluminum rod segment moves toward the scraping component 4, thereby improving the stability of transporting the aluminum rod segment into the straight cylinder 407. At the same time, driven by the multi-axis translation mechanism 301, the support cylinder 602 and the inner puzzle plate 605 are maintained at the position located at one end of the extrusion rod 2011, and when the aluminum rod segment is extruded, the shape of one end of the aluminum rod segment is improved. A stable limiting support is formed. When the middle section of the aluminum rod segment continues to move into the straight cylinder 407, the impurities on the surface of the aluminum rod segment are scraped off by the end of the straight cylinder 407. Furthermore, driven by the driving motor 403, the driving gear 4031 cooperates with the ring rack 406 and the limiting effect of the limiting groove 4021 on the limiting ring 4022 to continuously drive the rotating disk 404 and the straight cylinder 407 to rotate. The rotation of the straight cylinder 407 is utilized to improve the efficiency of the straight cylinder 407 in removing impurities on the surface of the aluminum rod segment, thereby avoiding the problem of local impurities being difficult to remove due to dead angles on the surface of the aluminum rod segment. After passing through the die hole of the die hole seat 1, the aluminum rod segment passes through the die seat 9 to form an aluminum rod product of required specifications.

[0054] Second embodiment

[0055] See also Figure 1-5 As shown, in the process of the extrusion rod 2011 pushing the aluminum rod segment into the die hole seat 1, due to the strong plasticity of the aluminum rod segment itself, the aluminum rod segment will be deformed and partially bent when subjected to force, resulting in cracks or folds at the bent portion of the aluminum rod segment during the extrusion process. In this regard, the following embodiments are proposed to solve the above problems:

[0056] A connecting rod 4071 is provided on the circumference of the straight cylinder 407, and an electromagnetic lock 4072 is provided on the end of the connecting rod 4071 away from the straight cylinder 407. A locking groove is provided on the side of the support ring 502 close to the straight cylinder 407, and the locking groove corresponds to the electromagnetic lock 4072. After the electromagnetic lock 4072 is docked and fixed to the locking groove, the straight cylinder 407 and the support ring 502 rotate synchronously under the drive of the driving motor 403.

[0057] During the processing, the two ends of the aluminum rod segment are respectively connected to the straight cylinder 407 and the cylinder. During the process in which the main oil cylinder 201 and the first side oil cylinder 202 drive the extrusion rod 2011 to extrude and move in the direction of the die hole seat 1, the multi-axis translation mechanism 301 drives the support cylinder 602 and the cylinder to move horizontally, so that the inner puzzle plate 605 constituting the cylinder repeatedly moves horizontally along the side wall of the aluminum rod segment between the support ring 502 and the extrusion rod 2011. In this process, the pressure sensor 6041 between the inner puzzle plate 605 and the elastic member 604 is used to detect the offset direction of the aluminum rod segment. Specifically, after the aluminum rod segment is partially bent to one side, the multi-axis translation mechanism 301 drives the support cylinder 602 and the cylinder to move to this position, and at the same time, the bent part of the aluminum rod segment will press the inner puzzle plate 605 on the bent side. The plate 605 is extruded, and the elastic member 604 corresponding to the extruded side will shrink. At the same time, the pressure sensor 6041 corresponding to the inner panel 605 reaches a preset pressure threshold. At this time, according to the bending direction of the aluminum rod segment, the locking mechanism in the supporting segment 509 releases the fixation of the rotating ring 508, and then the supporting ring 502 is driven by the multi-axis translation mechanism 301 to approach the straight cylinder 407, and the locking groove is connected with the electromagnetic lock 4072. The electromagnetic lock 4072 opens the lock. At this time, the supporting ring 502 rotates coaxially with the straight cylinder 407, and the driving motor 403 drives the rotating disk 404, the straight cylinder 407 and the supporting ring 502 to rotate through the cooperation of the driving gear 4031 and the ring rack 406, so that the two balls 507 correspond to the bending direction of the aluminum rod segment. At this time, the supporting ring 502 The locking mechanism in the segment 509 continues to fix the rotating ring 508, and the electromagnetic lock 4072 is released from the locking groove. The two sets of electric telescopic rods 504 drive the clamping rod 505 and the ball 507 to move inward, so that the inner side of the ball 507 is in close contact with the side wall of the aluminum rod segment, and then the multi-axis translation mechanism 301 drives the support ring 502 to move in the direction of the support tube 602. In the process of the support ring 502 moving in the direction of the support tube 602, the multi-axis translation mechanism 301 gradually increases the moving distance of the support ring 502 in the direction of the support tube 602, and in this process, the two balls 507 roll the curved section of the aluminum rod segment. The curved portion of the aluminum rod segment is gradually straightened in the process of repeated horizontal movement of the two balls 507. As the curved portion of the aluminum rod segment is Gradually reset, the multi-axis translation mechanism 301 drives the support ring 502 to move farther and farther in the direction of the support tube 602, and the support ring 502 will also be closer and closer to the support tube 602. At the same time, the pressure value detected by the pressure sensor 6041 on the side corresponding to the bending direction of the aluminum rod segment will also be lower and lower. When the pressure value detected by the pressure sensor 6041 returns to the normal standard, it means that the two balls 507 correct the bending part of the aluminum rod segment, so as to avoid the aluminum rod segment being bent and not corrected, and further causing cracks, folding and other problems due to deformation during the continued extrusion process. Subsequently, the two sets of electric telescopic rods 504 shrink to reduce the restraining effect of the balls 507 on the aluminum rod segment, and the multi-axis translation mechanism 301 drives the support ring 502 to reset again.By locking the electromagnetic lock 4072 and the locking groove, the two balls 507 are restored to the corresponding state up and down with the driving motor 403, and the aluminum rod segment is continuously supported stably. Meanwhile, the multi-axis translation mechanism 301 continues to drive the support cylinder 602 and the inner plate 605 to move horizontally along the aluminum rod segment, and the straightness of the aluminum rod segment during the extrusion process is detected in real time.

[0058] In addition, when the aluminum rod segment is subjected to stress, the diameter of the aluminum rod segment will increase locally due to deformation. In this process, cracks are likely to form on the aluminum rod segment. In this case, the deformation area cannot be corrected by rolling the two balls 507 when they move horizontally. Moreover, as the extrusion rod 2011 extrudes the aluminum rod segment, the cracks will further expand into the interior of the aluminum rod segment, affecting the normal extrusion and transportation of the aluminum rod segment. In this regard, the following embodiments are proposed to solve the problem:

[0059] When in use, when the support tube 602 and the inner panels 605 are repeatedly moved horizontally under the drive of the multi-axis translation mechanism 301, when the multiple inner panels 605 are compressed at the same time, it means that the aluminum rod segment and the corresponding positions of the multiple inner panels 605 are deformed to increase in diameter. At this time, the electromagnetic lock 4072 is docked with the locking groove under the drive of the multi-axis translation mechanism 301, and then the locking mechanism in the supporting section 509 releases the locking fixation of the rotating ring 508. At this time, the clamping rod 505 and the ball 507 are driven inward by the two sets of electric telescopic rods 504, so that the two ball 507 are close to the side wall of the aluminum rod segment, and Driven by the multi-axis translation mechanism 301, it moves to the position where the diameter of the aluminum rod segment increases. When the driving motor 403 continuously drives the rotating disk 404, the straight cylinder 407 and the support ring 502 to rotate rapidly through the driving gear 4031 and the ring rack 406, the multi-axis translation mechanism 301 synchronously cooperates to move toward the direction of the support cylinder 602, so that the two balls 507 gradually move toward the area where the deformation diameter increases on the aluminum rod segment during the rapid rotation, and use the plasticity of the aluminum rod segment under the high temperature state to roll the area where the deformation diameter increases on the aluminum rod segment, so as to correct the area where the deformation diameter increases on the aluminum rod segment.

[0060] Among them, when the multi-axis translation mechanism 301 drives the support tube 602 and the inner plate 605 to move rapidly horizontally on the aluminum rod segment, when the inner plate 605 detects a pressure change through the pressure sensor 6041, it immediately drives the support tube 602 and the inner plate 605 to move toward one end of the extrusion rod 2011, and then moves toward the support ring 502 to ensure that when the inner plate 605 detects that the aluminum rod segment is bent or the diameter increases due to deformation, the area where the aluminum rod segment is bent or the diameter increases is located on the left side of the inner plate 605, and the support tube 602 and the inner plate 605 are located on the side close to the extrusion rod 2011, so as to prevent the support tube 602 and the inner plate 605 from affecting the correction of the deformed aluminum rod segment by the ball 507.

[0061] Third embodiment

[0062] An extrusion method for an aluminum rod forming device comprises the following steps:

[0063] S1. First, the ingot feeding mechanism 11 delivers the aluminum rod segment to the corresponding position of the extrusion rod 2011. The cooperation of the straight cylinder 407 and the inner puzzle plate 605, as well as the induction detection of the pressure sensor 6041, determines whether the aluminum rod segment is straight, and ensures that the aluminum rod segment is extruded and transported in a straight state toward the die hole seat 1.

[0064] S2. With the push of the extrusion rod 2011, the ball 507 maintains stable support for the aluminum rod segment, and the straight cylinder 407 scrapes away impurities on the surface of the aluminum rod segment. The rotating component drives the straight cylinder 407 to improve the cleaning efficiency of impurities on the surface of the aluminum rod segment.

[0065] S3. During the process of the extrusion rod 2011 extruding and conveying the aluminum rod segment, the straightness of the aluminum rod segment during the extrusion process is detected by coordinating the horizontal movement of the pressure sensor 6041 during the horizontal movement of the support cylinder 602.

[0066] S4. According to the detection result of the pressure sensor 6041, when correction is needed, the support ring 502 drives the ball 507 to move horizontally, and the ball 507 cooperates with the rotation of the rotating assembly to correct the non-straight area of ​​the aluminum rod segment.
