Description

Technical Field

[0001] This invention relates to the field of aluminum alloy manufacturing technology, and more specifically to a high-precision slow-speed extrusion aluminum material pressure stabilization drive device. Background Technology

[0002] In the aluminum extrusion process, aluminum ingots are usually heated and fed into an extrusion die. A hydraulic cylinder drives the extrusion head to push the aluminum ingot into the die cavity, thereby obtaining an aluminum profile with the desired cross-sectional shape.

[0003] Existing extrusion devices mostly employ a single hydraulic cylinder for direct push, with processes such as aluminum ingot feeding, positioning, extrusion, and die cleaning often relying on manual assistance or separate actuators. This results in poor overall equipment coordination and low automation. Especially in slow, high-precision extrusion applications, ensuring the coaxiality of the aluminum ingot with the guide hole and extrusion head is difficult, easily leading to eccentric extrusion and affecting the dimensional accuracy and surface quality of the aluminum profiles. Furthermore, after extrusion, thin aluminum sheets often remain at the die's flow holes. If not cleaned promptly, these sheets can clog the flow holes or mix into the next batch of ingots, causing product defects. Currently, common cleaning methods involve manual shutdown or external air-blowing devices, which are not only inefficient but also increase production downtime. Therefore, there is an urgent need for a drive device that can achieve automatic and precise aluminum ingot feeding, stable pressure during extrusion, and automatic die cleaning to improve the precision and continuity of aluminum extrusion processing.

[0006] Preferably, the output shaft of the first hydraulic cylinder is arranged vertically, and a pusher is fixedly connected to the output end of the first hydraulic cylinder. A trigger plate is fixedly connected to the bottom of the pusher, and two trigger plates are symmetrically arranged.

[0009] Preferably, the extrusion die is fixedly installed on the top of the base, and a diversion hole is provided on the side of the extrusion die facing the guide frame.

[0010] Preferably, two motion mechanisms are symmetrically arranged. Each motion mechanism includes a fixed frame and a sliding rod. The fixed frame is fixedly installed on the top of the base. A rotating rod is rotatably installed on the fixed frame. A first connecting rod and a second connecting rod are provided between the rotating rod and the sliding frame. One end of the first connecting rod is fixedly connected to the rotating rod, and the other end of the first connecting rod is hinged to one end of the second connecting rod. The other end of the second connecting rod is hinged to the sliding frame.

[0011] Preferably, an eccentric block is fixedly connected to one end of the rotating rod, a motion frame is provided on the top of the eccentric block, a guide arc surface and a positioning plane are provided on the motion frame, and a coil spring is sleeved on the surface of the rotating rod.

[0012] Preferably, a sliding block is fixedly connected to the motion frame, the bottom end of the sliding rod is fixedly connected to the top of the base, the sliding block is sleeved on the surface of the sliding rod, and a compression spring is sleeved on the surface of the sliding rod.

[0013] Preferably, the scraping mechanism includes a scraper, a guide block, a connecting rod, and a guide rod. Two guide blocks are symmetrically arranged, and the scraper is located between the two guide blocks. The guide blocks and the scraper are fixedly connected by a connecting rod.

After each extrusion cycle, the residual aluminum skin on the surface of the diversion hole is automatically scraped off without manual intervention or additional power source, achieving mechanical synchronization of the cleaning and feeding actions. This effectively prevents aluminum skin accumulation and blockage, ensuring the surface quality of profiles produced continuously. In addition, the trigger plate cooperates with the guide arc surface and positioning plane on the motion frame, and uses spring force and mechanical limit to achieve precise control of motion timing, avoiding delays or malfunctions that may occur in electrical control. The overall structure is compact and reliable in operation, which improves the automation level and product consistency of the aluminum extrusion production line. Attached Figure Description

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 2 This invention provides a high-precision slow-speed extrusion aluminum material stabilizing drive device, including a base 1, a first hydraulic cylinder 2 at the bottom of the base 1, a second hydraulic cylinder 3, a guide frame 4, an extrusion die 5, a motion mechanism 6, and a scraping mechanism 7 at the top of the base 1. The first hydraulic cylinder 2 is used to drive the aluminum ingot to rise and fall to achieve intermittent feeding, the second hydraulic cylinder 3 is used to drive the aluminum ingot to move horizontally to achieve extrusion forming, the guide frame 4 is used to guide the aluminum ingot to keep it coaxially aligned with the extrusion die 5, the extrusion die 5 is used to extrude the aluminum ingot, the motion mechanism 6 is used to drive the guide frame 4 to approach the extrusion die 5 during feeding, and to drive the guide frame 4 away from the extrusion die 5 during resetting, and the scraping mechanism 7 is used to automatically clean the surface residue of the extrusion die 5 when the guide frame 4 moves away.

[0029] Reference Figures 1 to 9 The output shaft of hydraulic cylinder 2 is vertically arranged, and a pusher frame 21 is fixedly connected to the output end of hydraulic cylinder 2. A trigger plate 22 is fixedly connected to the bottom of the pusher frame 21, and two trigger plates 22 are symmetrically arranged. The vertically arranged hydraulic cylinder 2 drives the pusher frame 21 to rise and fall. With the help of the symmetrically arranged trigger plates 22, intermittent automatic feeding of aluminum ingots is realized. The trigger plates 22 can accurately trigger the subsequent motion mechanism 6, providing stable timing coordination for the horizontal extrusion action. The structure is compact and conducive to improving the feeding positioning accuracy.

[0030] Furthermore, the second hydraulic cylinder 3 is fixedly installed on the top of the base 1. The output shaft of the second hydraulic cylinder 3 is horizontally arranged, and the output end of the second hydraulic cylinder 3 is fixedly connected to the extrusion head 31. The horizontally arranged second hydraulic cylinder 3 and the extrusion head 31 provide a stable and controllable horizontal extrusion force. They are orthogonal to the vertical feeding action and do not interfere with each other, which facilitates slow and high-precision extrusion forming and ensures the dimensional consistency of the aluminum profile.

[0031] Furthermore, a guide hole 41 is provided through the guide frame 4, and a sliding frame 42 is fixedly connected to the bottom of the guide frame 4. Two sliding frames 42 are symmetrically arranged. A slide rail 43 is fixedly installed on the top of the base 1. Two slide rails 43 are arranged corresponding to the sliding frames 42, and the sliding frames 42 and slide rails 43 form a sliding guide engagement. Through the sliding guide engagement of the sliding frames 42 and slide rails 43, the guide frame 4 ensures that the guide hole 41 and the extrusion die 5 always maintain a high degree of coaxiality, improves the centering accuracy during aluminum ingot feeding, and avoids product defects caused by eccentric extrusion.

[0032] Furthermore, the extrusion die 5 is fixedly installed on the top of the base 1, and a flow diversion hole 51 is provided on the side of the extrusion die 5 facing the guide frame 4. The flow diversion hole 51 on the extrusion die 5 can reasonably divert the aluminum ingot, reduce the forming resistance, improve the uniformity of metal flow, and thus improve the cross-sectional quality and mechanical properties of the aluminum profile.

[0033] Furthermore, two motion mechanisms 6 are symmetrically arranged. Each motion mechanism 6 includes a fixed frame 61 and a sliding rod 68. The fixed frame 61 is fixedly installed on the top of the base 1. A rotating rod 62 is rotatably mounted on the fixed frame 61. A first connecting rod 64 and a second connecting rod 65 are provided between the rotating rod 62 and the sliding frame 42. One end of the first connecting rod 64 is fixedly connected to the rotating rod 62, and the other end of the first connecting rod 64 is hinged to one end of the second connecting rod 65. The other end of the second connecting rod 65 is hinged to the sliding frame 42. Through the linkage structure composed of the rotating rod 62, the first connecting rod 64, and the second connecting rod 65, the rotational motion of the rotating rod 62 is converted into the linear reciprocating motion of the sliding frame 42. The structure is simple, the transmission is reliable, and the forward and backward stroke of the guide frame 4 can be precisely controlled.

[0034] An eccentric block 63 is fixedly connected to one end of the rotating rod 62. A motion frame 66 is mounted on the top of the eccentric block 63. The motion frame 66 has a guide arc surface 661 and a positioning plane 662. A coil spring 621 is sleeved on the surface of the rotating rod 62. The eccentric block 63 cooperates with the guide arc surface 661 and the positioning plane 662 on the motion frame 66. Combined with the energy storage and release of the coil spring 621, the mechanical control and self-locking function of the motion sequence are realized, which improves the anti-interference ability and reliability of the system.

[0035] A sliding block 67 is fixedly connected to the motion frame 66, and the bottom end of the sliding rod 68 is fixedly connected to the top of the base 1. The sliding block 67 is sleeved on the surface of the sliding rod 68, and a compression spring 681 is sleeved on the surface of the sliding rod 68. The sliding block 67 slides up and down along the sliding rod 68, and the compression spring 681 provides a stable restoring force. When linked with the trigger plate 22, it can smoothly drive the motion frame 66 to rise and fall, ensuring smooth contact and separation between the eccentric block 63 and the guide arc surface 661 and the positioning plane 662.

[0036] In operation, the conveyor belt transports the aluminum ingot. When the ingot is transported to the top of the pusher frame 21, the output end of the first hydraulic cylinder 2 extends upward, and the pusher frame 21 and the aluminum ingot move upward synchronously. During this process, the trigger plate 22 gradually releases its pressure on the top of the moving frame 66, and the elastic force of the compression spring 681 is gradually released. The elastic force of the compression spring 681 drives the moving frame 66 and the sliding block 67 to move upward along the sliding rod 68. At the same time, the positioning plane 662 of the moving frame 66 gradually separates from the eccentric block 63. Afterward, the guide arc surface 661 of the moving frame 66 contacts the eccentric block 63. As the motion frame 66 moves upward, the guide arc surface 661 and the eccentric block 63 gradually separate. During the separation of the guide arc surface 661 and the eccentric block 63, the elastic force of the coil spring 621 is gradually released. The elastic force of the coil spring 621 drives the rotating rod 62 to rotate around its own axis. The rotating rod 62 rotates and drives the first connecting rod 64 to rotate synchronously around the axis of the rotating rod 62. The first connecting rod 64 rotates and drives the sliding frame 42 to slide synchronously along the slide rail 43 through the second connecting rod 65. The guide frame 4 moves synchronously towards the direction of the extrusion die 5. After that, the push frame 21 and the aluminum ingot as a whole continue to move upward. When the guide hole 41, aluminum ingot and extrusion head 31 are coaxially distributed, the output end of hydraulic cylinder 3 extends, and extrusion head 31 pushes aluminum ingot into guide hole 41. Aluminum ingot passes through guide hole 41 and enters extrusion die 5 through diversion hole 51 to obtain aluminum profile. Aluminum profile is sent to subsequent production and processing equipment. Afterwards, the output end of hydraulic cylinder 3 shortens and pulls the extrusion head 31 back to its initial position, the output end of hydraulic cylinder 2 shortens downward, and the pusher 21 also moves downward synchronously. When the trigger plate 22 contacts the top of the motion frame 66, the trigger plate 22 pushes the motion frame 66 downward synchronously, and the sliding block 67 slides downward synchronously along the sliding rod 68. The compression spring 681 contracts and its elastic force increases under the compression of the sliding block 67. When the guide arc surface 661 of the motion frame 66 contacts the eccentric block 63, along with the downward movement of the motion frame 66, the eccentric block 63 and the rotating rod 62 rotate synchronously around the axis of the rotating rod 62, and the coil spring 621 gradually... As the tension increases, the rotating rod 62 rotates and drives the first connecting rod 64 to rotate synchronously around the axis of the rotating rod 62. The rotation of the first connecting rod 64 drives the sliding frame 42 to slide synchronously along the slide rail 43 through the second connecting rod 65. The guide frame 4 moves synchronously in the direction away from the extrusion mold 5. When the guide arc surface 661 of the moving frame 66 separates from the eccentric block 63, the positioning plane 662 of the moving frame 66 and the eccentric block 63 abut against each other. At this time, the push frame 21 also returns to its initial position. Under the combined action of the positioning plane 662 and the eccentric block 63, the elastic force of the coil spring 621 and the compression spring 681 cannot be released, and all components remain stationary.

[0037] In summary, by driving the pusher frame 21 and trigger plate 22 to rise and fall through the vertically arranged hydraulic cylinder 2, and cooperating with the horizontally arranged hydraulic cylinder 3 and extrusion head 31, combined with the sliding guide mechanism formed by the guide frame 4, sliding frame 42 and slide rail 43, automatic and precise feeding of aluminum ingots and slow-speed high-precision extrusion are achieved. This effectively ensures the coaxiality of the guide hole 41, aluminum ingot and extrusion head 31, and improves the positioning accuracy and pressure stability of the extrusion process. In the motion mechanism 6, the rotating rod 62, the first connecting rod 64, the second connecting rod 65, the eccentric block 63, the motion frame 66, and its guiding arc surface 661 and positioning plane 662, together with the elastic force of the coil spring 621 and the compression spring 681, enable the guide frame 4 to automatically approach the extrusion die 5 when the push frame 21 rises and automatically move away when it falls. Stable self-locking is achieved when the positioning plane 662 abuts against the eccentric block 63. The entire motion sequence does not require electrical control and is completed by mechanical linkage. The structure is compact and the operation is reliable. At the same time, it also reserves space for the scraping operation of the subsequent scraping mechanism 7, ensuring that there is sufficient clearance between the guide frame 4 and the extrusion die 5 when the scraping mechanism 7 is working, so as to achieve avoidance.

[0038] Furthermore, the scraping mechanism 7 includes a scraper 71, a guide block 72, a hook rod 74, and a guide rod 75. Two guide blocks 72 are symmetrically arranged, and the scraper 71 is located between the two guide blocks 72. The guide blocks 72 and the scraper 71 are fixedly connected by a connecting rod 73. Two guide rods 75 are symmetrically arranged, and the bottom end of the guide rod 75 is fixedly connected to the top of the base 1. The guide block 72 is sleeved on the surface of the guide rod 75. Two hook rods 74 are symmetrically arranged, one end of the hook rod 74 is rotatably connected to the connecting rod 73, and the other end of the hook rod 74 is hinged to the sliding frame 42.

[0039] When in use, when the guide frame 4 moves toward the extrusion mold 5, the sliding frame 42 moves and at the same time drives the scraper 71, connecting rod 73 and guide block 72 to move upward along the guide rod 75 through the hook rod 74, so that the scraper 71 moves upward to the top of the extrusion mold 5. When the guide frame 4 moves away from the extrusion die 5, the sliding frame 42 moves simultaneously, driving the scraper 71, connecting rod 73 and guide block 72 to move downward along the guide rod 75 via the hook rod 74. During the movement of the scraper 71, the aluminum skin remaining on the surface of the diversion hole 51 is scraped off, and the scraped aluminum skin falls downward under its own gravity.

[0040] In summary, the scraping mechanism 7 links the scraper 71 with the sliding frame 42 through symmetrically arranged guide blocks 72, connecting rods 73 and hook rods 74. Each time the guide frame 4 resets and moves away from the extrusion die 5, the hook rod 74 drives the scraper 71 to move automatically downward along the guide rod 75, accurately scraping off the aluminum skin remaining on the surface of the diversion hole 51. The cleaning action does not require an additional power source or manual intervention, and is completed by the mechanical movement sequence of the equipment itself, which significantly improves the cleaning efficiency and reliability. The scraped aluminum skin falls off by its own weight, avoiding accumulation and blockage of the diversion hole 51, effectively ensuring the smooth entry of subsequent aluminum ingots into the die and the surface quality of the profile. At the same time, it simplifies equipment maintenance requirements and improves the continuous automation level of the aluminum extrusion production line.

[0041] The working principle of this invention: The conveyor belt transports the aluminum ingot. When the aluminum ingot is transported to the top of the pusher 21, the output end of the first hydraulic cylinder 2 extends upward, and the pusher 21 and the aluminum ingot move upward synchronously. During this process, the trigger plate 22 gradually releases the pressure on the top of the moving frame 66, and the elastic force of the compression spring 681 is gradually released. The elastic force of the compression spring 681 drives the moving frame 66 and the sliding block 67 to move upward along the sliding rod 68. At the same time, the positioning plane 662 of the moving frame 66 gradually separates from the eccentric block 63. Then, the guide arc surface 661 of the moving frame 66 contacts the eccentric block 63, and as the moving frame 66 moves upward, the guide arc surface 661 gradually separates from the eccentric block 63. During the separation of the guide arc surface 661 from the eccentric block 63, the elastic force of the coil spring 621 is gradually released. The elastic force of the coil spring 621 drives the rotating rod 62 to rotate around its own axis. The rotating rod 62 rotates and drives the first connecting rod 64 to rotate synchronously around the axis of the rotating rod 62. The first connecting rod 64 rotates and drives the sliding frame 42 to slide synchronously along the slide rail 43 through the second connecting rod 65. The guide frame 4 moves synchronously towards the extrusion die 5. After that, the push frame 21 and the aluminum ingot as a whole continue to move upward. While the sliding frame 42 moves, it drives the scraper 71, the connecting rod 73 and the guide block 72 to move upward along the guide rod 75 through the hook rod 74, so that the scraper 71 moves upward to the top of the extrusion die 5.

[0042] When the guide hole 41, aluminum ingot and extrusion head 31 are coaxially distributed, the output end of the second hydraulic cylinder 3 extends, and the extrusion head 31 pushes the aluminum ingot into the guide hole 41. The aluminum ingot passes through the guide hole 41 and enters the extrusion die 5 through the diversion hole 51 to obtain aluminum profile. The aluminum profile is then sent to subsequent production and processing equipment.

[0043] Afterwards, the output end of hydraulic cylinder 3 shortens and pulls the extrusion head 31 back to its initial position, the output end of hydraulic cylinder 2 shortens downward, and the pusher 21 also moves downward synchronously. When the trigger plate 22 contacts the top of the motion frame 66, the trigger plate 22 pushes the motion frame 66 downward synchronously, and the sliding block 67 slides downward synchronously along the sliding rod 68. The compression spring 681 contracts and its elastic force increases under the compression of the sliding block 67. When the guide arc surface 661 of the motion frame 66 contacts the eccentric block 63, along with the downward movement of the motion frame 66, the eccentric block 63 and the rotating rod 62 rotate synchronously around the axis of the rotating rod 62. The coil spring 621 gradually tightens and its elastic force increases. The rotating rod 62 rotates and drives the first connecting rod 64 to rotate synchronously around the axis of the rotating rod 62. The first connecting rod 64 rotates and... The sliding frame 42 is driven by the second connecting rod 65 to slide synchronously along the slide rail 43, while the guide frame 4 moves synchronously in the direction away from the extrusion mold 5. At the same time, the sliding frame 42 moves, and the scraper 71, connecting rod 73 and guide block 72 are driven to move downward along the guide rod 75 through the hook rod 74. During the movement of the scraper 71, the aluminum skin remaining on the surface of the diversion hole 51 is scraped off. The scraped aluminum skin falls downward under its own gravity. When the guide arc surface 661 of the moving frame 66 separates from the eccentric block 63, the positioning plane 662 of the moving frame 66 and the eccentric block 63 abut against each other. At this time, the pusher 21 also returns to the initial position downward. Under the cooperation of the positioning plane 662 and the eccentric block 63, the elastic force of the coil spring 621 and the compression spring 681 cannot be released, and all parts remain stationary.

[0044] The conveyor belt then transports the aluminum ingots to the top of the pusher 21, and the above steps are repeated in a continuous cycle.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
