Description

Technical Field

[0001] The invention relates to the technical field of extrusion molding equipment, and in particular to aluminum profile extrusion molding equipment. Background Art

[0002] The production process of aluminum profiles is a complex and sophisticated process, which mainly includes raw material preparation, smelting and casting, extrusion molding, heat treatment, surface treatment and finished product inspection. Among them, extrusion molding is the core link in the production process of aluminum profiles. Its main function is to extrude and deform the heated aluminum ingot through a mold to form a profile of the required shape and size. This process not only determines the cross-sectional shape of the aluminum profile, but also directly affects the dimensional accuracy, surface quality and mechanical properties of the product.

[0003] Aluminum profile extrusion molding equipment in the prior art, such as the Chinese patent document with authorization announcement number CN118357303B, discloses a high-precision aluminum profile extrusion molding equipment. The high-precision aluminum profile extrusion molding equipment flattens the raised portion of the cut surface of the aluminum rod body by cooperating with cylinder one and cylinder two, and then pushes the aluminum rod body into the feed barrel for extrusion operation, thereby avoiding the problem of extrusion operation failure caused by the downward protrusion of the cut surface of the aluminum rod body in the prior art.

[0004] However, during the extrusion process, the above-mentioned high-precision aluminum profile extrusion molding equipment in the prior art may easily cause the aluminum rod to bend or deviate due to excessive extrusion speed, excessive heating temperature or quality problems of the aluminum rod. This will reduce the dimensional accuracy of the aluminum profile and cause defects such as scratches and ripples on the surface, affecting the product quality of the aluminum profile. Summary of the invention

[0005] The present invention provides an aluminum profile extrusion molding device, aiming to solve the problem that an aluminum rod may be bent or offset during the extrusion molding process of the aluminum profile high-precision extrusion molding device in the related art.

[0006] The present invention provides an aluminum profile extrusion molding device that adopts the following technical solution: An aluminum profile extrusion forming device comprises a frame, a die and an extrusion rod for pushing an aluminum rod through the die are mounted on the frame, a correction mechanism located at a feeding end of the die is also arranged on the frame, the correction mechanism comprises a rotating sleeve coaxially arranged with the extrusion rod, a rotary driving member driving the rotating sleeve to rotate, and a plurality of correction units arranged in the rotating sleeve along the circumference of the rotating sleeve; Each of the correction units comprises a moving frame mounted on the rotating sleeve, a correction elastic member connected between the moving frame and the rotating sleeve to apply elastic force to the moving frame to move the moving frame inward, an unlocking pin mounted on the moving frame and moving radially along the rotating sleeve, a return spring connected between the unlocking pin and the rotating sleeve to apply elastic force to the unlocking pin to move the unlocking pin inward, a hinge rod mounted on the moving frame and having a hinge point opposite to the unlocking pin, and a correction roller mounted on the moving frame for abutting against the aluminum bar; The end of the unlocking pin near the rotating sleeve can be pushed by the aluminum rod, so that the unlocking pin pushes the hinge point of the hinge rod outward to drive the movable frame to move outward, so that the aluminum rod can pass through multiple correction units and be corrected by the pressure of multiple correction rollers.

[0007] By adopting the above technical scheme and setting up a correction mechanism, a correction force is applied to the aluminum rod along the circumference of the aluminum rod when the aluminum rod passes through the die, thereby eliminating the bent or offset part of the aluminum rod, so that the cross-section of the aluminum rod is restored and remains circular or nearly circular. This is conducive to the aluminum rod having better straightness and position accuracy, being able to pass through the die smoothly, reducing resistance and deformation during the extrusion process, and improving the product quality of the aluminum profile.

[0008] Furthermore, the aluminum profile extrusion forming equipment also includes a grinding roller installed on each movable frame for grinding the feeding end of the aluminum rod, the grinding roller is located on the side of the correction roller away from the mold, and the grinding roller is inclined outward from the mold toward the extrusion rod.

[0009] By adopting the above technical solution, the grinding roller is used to grind the feeding end of the aluminum rod when the aluminum rod enters the correction mechanism, so that the feeding end of the aluminum rod is conical, reducing the resistance during feeding, and helping the aluminum rod to pass through the die more smoothly during the extrusion process.

[0010] Furthermore, the frame is also provided with a clamping mechanism located on the side of the correction mechanism away from the mold, and the clamping mechanism includes a fixed frame, a fixed cylinder arranged on the fixed frame for passing the aluminum rod, a plurality of clamps arranged along the circumference of the fixed cylinder at one end of the fixed cylinder close to the correction mechanism, and a clamping driver driving each clamp to move radially along the fixed cylinder to clamp the aluminum rod.

[0011] Furthermore, a first elastic member is provided between the rotating sleeve and the fixing frame, and the first elastic member is used to apply an elastic force to the rotating sleeve to move the rotating sleeve toward the fixing frame.

[0012] Furthermore, a tension spring is arranged between each of the movable frames and the rotating sleeve, and the tension spring is used to apply elastic force to the movable frame to make the movable frame move toward the fixed frame.

[0013] Furthermore, one end of each correction roller close to the grinding roller is rotatably mounted on a movable frame and is equipped with a gear, and a rack capable of meshing with the gear is provided on the rotating sleeve.

[0014] By adopting the above technical solution, the rack is used to mesh with the gear when the extrusion rod retreats, thereby driving the correction roller to rotate, so that the correction roller rotates from a horizontal state to a vertical state and contacts the end face of the extrusion rod, and then the end face of the extrusion rod is cleaned in time under the drive of the rotary drive member, so as to prevent the end face of the extrusion rod from adhering to the aluminum material in this process, thereby affecting the normal progress of the next extrusion process.

[0015] Furthermore, each of the correction units also includes a support frame installed in the rotating sleeve through a second elastic member, and the support frame is located at one end of the rotating sleeve close to the mold and is used to support the correction roller.

[0016] By adopting the above technical solution, the second elastic member is used to provide elastic support for the support frame, so that the support frame can support the correction roller away from the end of the movable frame, ensuring that the correction roller remains stable during the correction process and can withstand the force generated during the correction process.

[0017] Furthermore, each of the unlocking pins is provided with a through slot for passing the hinged rod, and a push rod for pushing the hinged rod is arranged in the through slot; each of the hinged rods includes two hingedly connected rod bodies, and one end of each of the rod bodies away from the hinge point is connected to the corrective elastic member through an elastic telescopic rod.

[0018] Furthermore, the end of each unlocking pin close to the rotating sleeve is hemispherical.

[0019] With the above technical solution, the hemispherical design can reduce damage to the aluminum rod while providing a smooth unlocking action.

[0020] Furthermore, each of the correction rollers includes a main shaft and a roller body rotatably mounted on the main shaft. The end of the main shaft is provided with an oil injection hole and an oil injection switch for controlling the oil injection hole switch. The frame is also provided with a mold base for mounting the mold, and the mold base is provided with a protrusion that can press the oil injection switch.

[0021] By adopting the above technical solution, the oil injection hole is used to spray lubricating oil to the die during the extrusion process to reduce the friction between the aluminum material and the die, thereby reducing the adhesion of the aluminum material to the die.

[0022] The beneficial effects of an aluminum profile extrusion forming device provided by the present invention are as follows: through the setting of a correction mechanism, a correction force is applied to the aluminum rod along the circumference of the aluminum rod when the aluminum rod passes through the die, eliminating the bent or offset part of the aluminum rod, so that the cross section of the aluminum rod is restored and maintained to be circular or nearly circular, which is conducive to the aluminum rod having better straightness and position accuracy, being able to pass through the die smoothly, reducing the resistance and deformation during the extrusion process, and improving the product quality of the aluminum profile; in addition, the correction roller of the correction mechanism is set as a rotatable structure, so that the correction roller can be switched between a horizontal state and a vertical state, so that the correction roller can clean the end face of the extrusion rod in time when the extrusion rod retreats, avoiding the end face of the extrusion rod from adhering to the aluminum material in this process, affecting the normal progress of the next extrusion process; and through the setting of a grinding roller, the feeding end of the aluminum rod is ground when the aluminum rod enters the correction mechanism, so that the feeding end of the aluminum rod is conical, reducing the resistance during feeding, and helping the aluminum rod to pass through the die more smoothly during the extrusion process.

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] like Figures 1 to 4 As shown, an embodiment of the aluminum profile extrusion forming equipment of the present invention includes a frame 10, a die base 20, a die 210, an extrusion rod 40, an extrusion drive member 410, a correction mechanism 50, a grinding roller 60, a clamping mechanism 70, and a lifting bracket 80.

[0030] The die base 20 is fixedly mounted on the frame 10, and the die 210 is detachably mounted on the die base 20. The die 210 has a hole of the required cross-sectional shape of the aluminum profile, and the aluminum rod 30 forms a corresponding shape when passing through the die 210. The correction mechanism 50 is arranged on the frame 10 and located at the feeding end of the die 210, and is used to apply a correction force to the aluminum rod 30 along the circumference of the aluminum rod 30 when the aluminum rod 30 passes through the die 210, eliminate the bending or offset part of the aluminum rod 30, so that the cross section of the aluminum rod 30 is restored and remains circular or nearly circular, which is conducive to the aluminum rod 30 having better straightness and position accuracy, and can smoothly pass through the die 210, reducing resistance and deformation during the extrusion process. The grinding roller 60 is arranged on the correction mechanism 50, and is used to grind the feeding end of the aluminum rod 30 when the aluminum rod 30 enters the correction mechanism 50, so that the feeding end of the aluminum rod 30 is conical, reducing resistance during feeding, and helping the aluminum rod 30 to pass through the die 210 more smoothly during the extrusion process. The clamping mechanism 70 is arranged on the frame 10 and is located on the side of the correction mechanism 50 away from the die 210, and is used to clamp and fix the aluminum rod 30 when the grinding roller 60 grinds the aluminum rod 30. The lifting bracket 80 is arranged on the frame 10 and is located on the side of the clamping mechanism 70 away from the correction mechanism 50, and is used to transport the aluminum rod 30 heated to the required extrusion temperature upward to the feeding end of the clamping mechanism 70. The extrusion rod 40 and the extrusion driving member 410 are respectively arranged on the frame 10 and are located on the side of the lifting bracket 80 away from the clamping mechanism 70. The extrusion driving member 410 is connected to the extrusion rod 40 and is used to provide the power required for extrusion, so as to drive the extrusion rod 40 to push the heated aluminum rod 30 through the die 210.

[0031] The correction mechanism 50 includes a rotating sleeve 510 coaxially arranged with the extrusion rod 40, a rotary driving member 560 driving the rotating sleeve 510 to rotate, and a plurality of correction units 540 arranged in the rotating sleeve 510 along the circumference of the rotating sleeve 510. The number of the correction units 540 in the embodiment is set to three. In other embodiments, the number of the correction units 540 can be adjusted according to actual needs and production requirements. When the cross-sectional shape of the aluminum profile is complex or the size is large, the number of the correction units 540 can also be set to four, five, etc. The more the number of correction units 540, the more uniform and stable the correction force can be provided, which helps to improve the dimensional accuracy and surface quality of the profile.

[0032] Each correction unit 540 includes a moving frame 541 mounted on the rotating sleeve 510, a correction elastic member 543 connected between the moving frame 541 and the rotating sleeve 510 to apply elastic force to the moving frame 541 so that the moving frame 541 moves inward, a tension spring 542 connected between the moving frame 541 and the rotating sleeve 510 to apply elastic force to the moving frame 541 so that the moving frame 541 moves toward the clamping mechanism 70, and a tension spring 542 connected between the moving frame 541 and the rotating sleeve 510 to apply elastic force to the moving frame 541 so that the moving frame 541 moves toward the clamping mechanism 70. An unlocking pin 544 movably assembled on the movable frame 541, a return spring 547 connected between the unlocking pin 544 and the rotating sleeve 510 to apply elastic force to the unlocking pin 544 to move the unlocking pin 544 inward, a hinge rod 548 installed on the movable frame 541 and with a hinge point opposite to the unlocking pin 544, a correction roller 550 installed on the movable frame 541 for abutting the aluminum rod 30, and a support frame 556 installed in the rotating sleeve 510 through a second elastic member 557.

[0033] The end of each unlocking pin 544 near the rotating sleeve 510 is hemispherical, and is used to be pushed outward by the aluminum rod 30, thereby triggering the correction unit 540 to automatically unlock. The hemispherical design can reduce damage to the aluminum rod 30 and provide a smooth unlocking action. Each unlocking pin 544 is provided with a through slot 545 for passing through the hinge rod 548, and a push rod 546 for pushing the hinge point of the hinge rod 548 is arranged in the through slot 545. Each hinge rod 548 includes two hinged rod bodies, and one end of each rod body away from the hinge point is connected to the correction elastic member 543 through an elastic telescopic rod 549. By pushing the hinge point of the hinge rod 548 through the unlocking pin 544, the hinge rod 548 can act as a lever, so that a small input force (the push of the aluminum rod 30) generates a large force (the correction force of the correction roller 550) at the hinge point, thereby amplifying the force, so that the moving frame 541 moves outward to allow the aluminum rod 30 to pass through multiple correction units 540, and the correction elastic member 543 is compressed to store the correction force, thereby realizing an automated correction process. The correction elastic member 543 in the embodiment includes an inner rod and an outer rod that are mutually sleeved, and a spring connected between the inner rod and the outer rod.

[0034] One end of each correction roller 550 close to the grinding roller 60 is rotatably mounted on the mobile frame 541 and equipped with a gear 551, and a rack 530 capable of meshing with the gear 551 is fixedly arranged on the rotating sleeve 510. The rack 530 is used to mesh with the gear 551 when the extrusion rod 40 retreats, thereby driving the correction roller 550 to rotate, so that the correction roller 550 rotates from a horizontal state to a vertical state and is tangent to the end face of the extrusion rod 40, and then the end face of the extrusion rod 40 is cleaned under the drive of the rotary drive member 560 to prevent the end face of the extrusion rod 40 from adhering to the aluminum material in this process, which affects the normal progress of the next extrusion process. In order to ensure the cleaning effect of the straightening roller 550 on the end surface of the extrusion rod 40, an extension rod 558 is provided on one of the straightening rollers 550 in the embodiment, and the end of the extension rod 558 away from the straightening roller 550 can contact the center of the end surface of the extrusion rod 40, thereby increasing the effective cleaning range of the straightening roller 550 and ensuring that the entire end surface of the extrusion rod 40 can be cleaned.

[0035] Each correction roller 550 includes a main shaft 552, a roller body 553 rotatably mounted on the main shaft 552, an oil injection hole 554 and an oil injection switch 555 for controlling the switch of the oil injection hole 554 are provided at the end of the main shaft 552, and a protrusion 211 capable of pressing the oil injection switch 555 is provided on the mold base 20. The oil injection hole 554 is used to spray lubricating oil to the mold 210 during the extrusion process to reduce the friction between the aluminum material and the mold 210, thereby reducing the adhesion of the aluminum material on the mold 210. The injection of lubricating oil can be continuous or intermittent. In the embodiment, the injection of lubricating oil is intermittent. Specifically, the number of protrusions 211 is set to one. During the extrusion process, the correction roller 550 rotates with the rotating sleeve 510 until the oil injection switch 555 is pressed by the protrusion 211, and the oil injection hole 554 is opened, and the lubricating oil is sprayed onto the mold 210 through the oil injection hole 554.

[0036] The support frame 556 is located at one end of the rotating sleeve 510 close to the mold 210, and is used to support the correction roller 550. The second elastic member 557 in the embodiment includes an inner rod and an outer rod that are mutually sleeved, and a spring connected between the inner rod and the outer rod. The second elastic member 557 is used to provide elastic support for the support frame 556, so that the support frame 556 can support the end of the correction roller 550 away from the moving frame 541, ensuring that the correction roller 550 remains stable during the correction process and can withstand the force generated during the correction process.

[0037] The grinding roller 60 corresponds to the correction unit 540 one by one and is installed on each moving frame 541. The grinding roller 60 is located on the side of the correction roller 550 away from the die 210 and tilted outward from the die 210 toward the extrusion rod 40. It is used to grind the feeding end of the aluminum rod 30 when the aluminum rod 30 enters the correction mechanism 50, so that the feeding end of the aluminum rod 30 is conical, reducing the resistance during feeding, and helping the aluminum rod 30 to pass through the die 210 more smoothly during the extrusion process.

[0038] The clamping mechanism 70 includes a fixing frame 710, a fixing cylinder 720 disposed on the fixing frame 710 for passing the aluminum rod 30, a plurality of clamps 730 disposed along the circumference of the fixing cylinder 720 and at one end of the fixing cylinder 720 close to the correction mechanism 50, and a clamping driver 740 for driving each clamp 730 to move radially along the fixing cylinder 720 to clamp the aluminum rod 30. When the grinding roller 60 grinds the aluminum rod 30, the clamping driver 740 drives each clamp 730 to move radially along the fixing cylinder 720 to clamp and fix the aluminum rod 30, thereby ensuring the stability of the aluminum rod 30 during the grinding process.

[0039] A first elastic member 520 is provided between the rotating sleeve 510 and the fixed frame 710. The first elastic member 520 is used to apply elastic force to the rotating sleeve 510 to move the rotating sleeve 510 toward the fixed frame 710, thereby ensuring a stable contact force between the grinding roller 60 and the aluminum rod 30 to avoid uneven grinding due to insufficient contact force.

[0040] The working process of the embodiment of the aluminum profile extrusion molding equipment of the present invention comprises the following steps: The first step is conveying. The lifting bracket 80 conveys the aluminum rod 30 heated to the required extrusion temperature upward to the feeding end of the clamping mechanism 70, and the extrusion driving member 410 drives the extrusion rod 40 to push the heated aluminum rod 30 to move toward the mold 210.

[0041] The second step is grinding. The feed end of the aluminum rod 30 extends between the multiple grinding rollers 60 in the rotating sleeve 510, and the grinding rollers 60 push the movable frame 541 to move in the rotating sleeve 510 toward the mold 210 until the movable frame 541 moves to the end of the rotating sleeve 510, and the tension spring 542 is stretched. Then, under the push of the aluminum rod 30, the rotating sleeve 510 moves toward the mold 210 until the rotating sleeve 510 and the mold base 20 are abutted, and the first elastic member 520 is stretched; clamping drive The device 740 drives each clamp 730 to move radially along the fixed cylinder 720 to clamp and fix the aluminum rod 30, the rotary drive member 560 drives the rotating sleeve 510 to rotate, and the grinding roller 60 grinds the feeding end of the aluminum rod 30 to make the feeding end of the aluminum rod 30 conical. Driven by the tension spring 542 and the elastic force of the first elastic member 520, a stable contact force is maintained between the grinding roller 60 and the aluminum rod 30 during grinding. After grinding is completed, the clamping driver 740 drives each clamp 730 to retract and reset to release the aluminum rod 30.

[0042] The third step is extrusion. The extrusion rod 40 continues to push the aluminum rod 30 to move toward the mold 210. The aluminum rod 30 pushes the unlocking pin 544 close to the end inside the rotating sleeve 510, so that the unlocking pin 544 pushes the hinge point of the hinge rod 548 outward to drive the movable frame 541 to move outward, triggering the correction unit 540 to automatically unlock, and the correction elastic member 543 is compressed to store the correction force; then the feeding end of the aluminum rod 30 pushes the correction roller 550 to rotate, so that the correction roller 550 rotates from a vertical state to a horizontal state, and the end of the correction roller 550 away from the movable frame 541 is supported by the support frame 556. The aluminum rod 30 passes through multiple correction units 540 and is corrected by the pressure of multiple correction rollers 550, and is formed into the desired aluminum profile cross-sectional shape through the mold 210.

[0043] The fourth step is cleaning. The extrusion drive 410 drives the extrusion rod 40 to retreat and reset. The pushing end of the extrusion rod 40 drives the movable frame 541 to move toward the fixed frame 710 by pushing the end of the unlocking pin 544. During the movement, the gear 551 engages with the rack 530 to drive the correction roller 550 to rotate, so that the correction roller 550 rotates from a horizontal state to a vertical state and is tangent to the end face of the extrusion rod 40. Then, the end face of the extrusion rod 40 is cleaned under the drive of the rotary drive 560.

[0044] Thus, the embodiment of the aluminum profile extrusion forming equipment of the present invention applies a correction force to the aluminum rod 30 along the circumference of the aluminum rod 30 when the aluminum rod 30 passes through the die 210 through the setting of the correction mechanism 50, thereby eliminating the bending or offset part of the aluminum rod 30, so that the cross section of the aluminum rod 30 is restored and maintained to be circular or nearly circular, which is conducive to the aluminum rod 30 having better straightness and position accuracy, being able to pass through the die 210 smoothly, reducing the resistance and deformation during the extrusion process, and improving the product quality of the aluminum profile; in addition, the correction roller 550 of the correction mechanism 50 is set to be rotatable The structure enables the correction roller 550 to switch between a horizontal state and a vertical state, so that the correction roller 550 can clean the end surface of the extrusion rod 40 in time when the extrusion rod 40 retreats, thereby preventing the end surface of the extrusion rod 40 from adhering to the aluminum material in this process and affecting the normal progress of the next extrusion process; and through the setting of the grinding roller 60, the feeding end of the aluminum rod 30 is ground when the aluminum rod 30 enters the correction mechanism 50, so that the feeding end of the aluminum rod 30 is conical, thereby reducing the resistance during feeding and helping the aluminum rod 30 to pass through the die 210 more smoothly during the extrusion process.
