Description

Technical Field

[0001] This invention relates to the field of metal forming technology, specifically to an aluminum alloy patterned tube support mechanism, extrusion device, and extrusion method. Background Technology

[0002] After the metal billet is heated and softened, it is forcefully pushed through the orifice of a die of a specific shape. The material undergoes plastic deformation under high pressure and flows outward. This hot extrusion or cold extrusion process uses the precise contour of the die to force the metal to flow and form, thereby obtaining a continuous profile or part with the desired cross-sectional shape. The patent application No. 202411124899.8 discloses an aluminum profile extrusion forming apparatus, which includes a push rod for pushing an aluminum rod to be extruded, an extrusion head, and a first spring. The inner side of the extrusion head and the outer side of the push rod are provided with a first drive thread that cooperates with each other. The extrusion head can rotate while moving back and forth relative to the push rod. When the push rod retracts, the first spring rebounds and pushes the extrusion head forward to keep in contact with the aluminum rod and rotate relative to it, so as to break the adhesive state between the extrusion head and the aluminum rod. After the first spring rebounds and resets, the extrusion head moves backward with the push rod and disengages from the aluminum rod. An aluminum removal mechanism is provided to push out the adhered aluminum. After the extruded tube is formed, some parts will be suspended in the air. When the existing support device supports it, the formed tube will move relative to the support structure during the extrusion process, causing relative sliding between the formed tube and the support structure. The formed tube is prone to wear during the extrusion output process, which affects the forming quality of the tube. Summary of the Invention

[0013] Preferably, the striking element further includes an elastic pad, which is fixedly disposed at the second end of the elastic plate and located on the side of the elastic plate away from the fixing element.

[0014] Preferably, the elastic pad is a hollow airbag with an exhaust port, and multiple heat-conducting strips are provided on the side of the airbag away from the elastic plate.

[0015] Preferably, the fastener extends along a second preset direction, and the first preset direction and the second preset direction form an angle; The distance between the fixing member and the conveying assembly gradually increases from the end closer to the profile extrusion die to the end farther away from the profile extrusion die.

[0016] Preferably, there are multiple adsorption elements, which are arranged at intervals along the length of the fixing element.

[0017] Preferably, the conveying assembly includes a base, a support frame, wheels, and a conveyor belt; The support frame is fixedly mounted on the base, the rotating wheel is rotatably mounted on the support frame, the conveyor belt is sleeved on the rotating wheel, and the base is used to be mounted on the extrusion side of the profile extrusion die.

[0018] The present invention also provides an extrusion device, the extrusion device comprising: case; A profile extrusion die, including an output end, wherein the profile extrusion die is disposed within the housing and is used to extrude and output shaped tubular components; The support mechanism is located at the output end of the profile extrusion die, and the support mechanism is used to support the formed tube.

[0019] Preferably, the output end of the profile extrusion die is provided with a guide support.

The telescopic rod is fixedly connected to the housing, and the telescopic end of the telescopic rod is fixedly connected to the V-shaped plate. The V-shaped plate is located between the first plate and the second plate, and can extend and retract with the telescopic rod to protrude or recess relative to the second plate.

[0022] This invention also provides a method for extruding aluminum alloy patterned tubes, the method comprising: Feeding: The aluminum alloy bar is fed into the profile extrusion die; Extrusion molding: The aluminum alloy bar is extruded by the profile extrusion module to produce a formed tube. Material conveying: The formed tube is conveyed along a first preset direction under the support of the support mechanism.

[0023] Preferably, the support mechanism further includes a striking component. The material conveying includes: The formed tube is supported on the plurality of support assemblies; The conveying component drives the formed tube to move along the first preset direction, and the striking component strikes the formed tube.

[0024] This invention provides an aluminum alloy patterned tube support mechanism, an extrusion device, and an extrusion method. It has the following beneficial effects: 1. The support mechanism pushes the support component through the extruded forming tube. The support component moves from left to right to support the forming tube, avoiding relative movement between the support and the forming tube during support, which would cause wear to the forming tube and affect the final forming quality of the forming tube.

[0025] 2. In this support mechanism, the air box pushes the air supply fan into the air chamber through the air inflator pipe, so that the exhaust hole at the top of the air chamber continuously discharges gas. The gas can support the forming tube, reduce the pressure on the outer wall of the forming tube, reduce the deformation caused by the pressure, and further reduce the friction between the forming tube and the support component, thereby improving the final forming quality of the forming tube.

[0026] 3. This support mechanism attracts the striking component through the adsorption component, causing the elastic plate to bend. Under the action of its own elastic force, the elastic plate strikes the surface of the formed tube, generating a gradually increasing impact on the formed tube. This avoids damage caused by sudden load, releases residual stress inside the material, and improves the quality of the forming process.

[0027] 4. This support mechanism uses airflow discharged through the exhaust holes at the top of the air chamber to blow on the surface of the forming tube, thereby cooling the forming tube. After cooling, the material becomes more brittle, which allows the stress wave from the impact of the elastic plate to propagate deeper, enhancing the stress relief effect of the impact and further improving the forming quality.

[0028] 5. When the extrusion device discharges the formed tube from the output end of the profile extrusion die, the guide support can exert a direct force on the die, preventing the extruded tube from being deformed due to gravity and torsional force pressing on the profile extrusion die. This avoids the deformation of the profile extrusion die affecting the extrusion process and thus the final forming quality.

[0029] 6. The aluminum alloy patterned tube extrusion method produces countless micro-scale straight grooves or countless parallel spiral grooves on the outer surface after forming. The frame tube will produce complex reflection and scattering effects on natural light. When light shines on the surface, it will form a unique light and shadow effect, which may present a soft luster or subtle changes in brightness, giving people a delicate and refined visual experience.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0034] Example 1: This invention provides a support mechanism: Please see the appendix Figure 1 and 2 , attached Figure 2 The direction indicated by the middle arrow is the first preset direction. A support mechanism is used to cooperate with a formed tube extruded by a profile extrusion die, comprising: The conveying component 1 is set along the extrusion output direction of the formed tube and moves along a first preset direction; Multiple support components 2 are spaced apart on the conveying surface of the conveying component 1 along a first preset direction. The support components 2 are used to support the formed tube and drive the formed tube to move synchronously with the conveying component 1.

[0035] During the extrusion process of the forming tube from the output end on the right side of the profile extrusion die 5, the right end of the forming tube will naturally droop due to gravity, which will push one of the support components 2. With continuous extrusion, the tube gradually moves in the first preset direction. The tube will push the support component 2 to the right, and drive the other support components 2 to move through the conveying component 1. As the forming tube moves to the right, the support components 2 move from the left to the right to support the forming tube. The support position of the support components 2 relative to the forming tube does not change, so as to avoid relative movement with the forming tube during support, which would cause wear on the forming tube and affect the quality of the forming tube.

[0036] Please see the appendix Figure 3 The support component 2 includes a support base 21 and an arc-shaped support member 22 that are fixedly connected. The end of the support base 21 away from the arc-shaped support member 22 is fixedly connected to the conveying surface of the conveying component 1. When the support member 22 is pushed, it can drive the conveyor belt 14. The arc-shaped support 22 includes an arc-shaped cavity for fitting with the formed tube. The arc-shaped cavity is arc-shaped so that it can match the outer wall of the formed tube, increasing the contact area and providing better support for the formed tube.

[0037] The formed tube is extruded from the output end on the right side of the profile extrusion die 5. The part at the farthest end in the first preset direction will naturally droop and hit the arc-shaped support 22, thereby pushing the conveying component 1 through the support component, and further pushing the remaining support components 2 through the conveying component 1.

[0038] Please see the appendix Figure 2 and 4 The conveying assembly 1 includes a base 11, a support frame 12, a rotating wheel 13, and a conveyor belt 14; The support frame 12 is fixedly mounted on the base 11, the rotating wheel 13 is rotatably mounted on the support frame 12, and the conveyor belt 14 is sleeved on the rotating wheel 13. The base 11 is used to be mounted on the extrusion side of the profile extrusion die. The two rotating wheels 13 are movably connected to the top of the support frame 12. The conveyor belt 14 is sleeved on the outer wall of the rotating wheel 13, and the conveyor belt 14 is driven by friction with the rotating wheel 13 through the inner wall.

[0039] When the support component 2 is pushed, it will further push the conveyor belt 14, so that the conveyor belt 14 will circulate under the support of the roller 13. The pushed conveyor belt will drive all the support components 2 to move, so that the support components 2 move to the bottom of the forming tube, cooperate with the movement of the extruded forming tube, and support it.

[0040] Example 2: Based on Example 1, the present invention provides a technical solution: Please see the appendix Figure 5 The support component 2 also includes a pneumatic component 23; The pneumatic assembly 23 includes an air chamber 231 and an inflation pipe 232 that are connected to each other, and the inflation pipe 232 is connected to the interior of the air chamber 231. The air chamber 231 is fixedly installed in the arc-shaped cavity of the arc-shaped support member 22. The air chamber 231 has multiple exhaust holes 233, and the gas in the air chamber 231 can be discharged through the multiple exhaust holes 233. The inflation tube 232 is used to connect to the air source so that the airflow is discharged through the exhaust hole 233 of the air chamber 231 to support the shaped tube.

[0041] A support bar 221 is also provided on the side of the air chamber 231 away from the arc-shaped support member 22. The support bar 221 extends along the arc direction of the air chamber 231 and is located on both sides of the exhaust hole 233. When lifting, the support bar 221 directly contacts the forming tube.

[0042] When the support component 2 lifts the formed tube, it can lift the formed tube through the air chamber 231 and the support bar 221. The air source continuously fills the air chamber 231 with gas through the air filling pipe 232, so that the exhaust hole 233 at the top of the air chamber 231 continuously discharges gas. The gas can act on the formed tube, which can lift the formed tube and reduce the pressure on the outer wall of the formed tube, reduce the deformation caused by the pressure on the outer wall of the formed tube, and further reduce the friction between the formed tube and the support component 2. At the same time, the airflow will flow quickly on the surface of the formed tube, which can accelerate the cooling of the formed tube.

[0043] Please see the appendix Figure 3 The support base 21 has a through hole that passes through the arc-shaped support member 22, and the inflation tube 232 passes through the through hole; The pneumatic assembly 23 also includes an air box 234 and an air supply fan 235. The air supply fan 235 is located at the air inlet of the air box 234. The end of the air pipe 232 away from the air chamber 231 is connected to the air box 234. The top of the air box 234 is open and is covered by the inner wall of the conveyor belt 14. The air pipe 232 located at the top of the air box is connected to the air box 234 through the internal hole.

[0044] The number of air chambers 231 is the same as the number of support components 2, and their positions correspond one-to-one.

[0045] The air supply fan 235 pushes outside air into the air box 234, increasing the air pressure inside the air box 234. The conveyor belt 14 can partially seal the air box 234. When the support component 2 is pushed to the top of the corresponding air box 234, the excessive air pressure inside the air box 234 will cause gas to enter the air chamber 231 through the air pipe 232.

[0046] Example 3: Based on Examples 1 and 2, the present invention provides a technical solution: Please see the appendix Figure 3 and 4 , attached Figure 4 The direction indicated by the middle arrow is the first preset direction. The support mechanism also includes a striking component 3, which includes a fixing member 31 and multiple striking members 32. An adsorption element 34 that can cooperate with the striking element 32 is provided on the fixing element 31; Multiple striking elements 32 are spaced apart on the conveying surface of the conveying assembly 1 along a first preset direction, and move synchronously with the conveying assembly 1 along the first preset direction; During the synchronous movement of the conveying component 1, multiple support components 2 and multiple striking components 32, the striking components 32 oscillate along a preset trajectory under the suction force of the adsorption component 34 to strike the formed tube.

[0047] When the formed tube is extruded in a preset direction, the support component 2 pushes the conveyor belt 14 in the conveying component to move, which in turn drives the striking component 32 to move. During the movement, the striking component 32 is subjected to the suction force of the adsorption component 34. As the striking component 32 moves in the first preset direction, it oscillates along the preset trajectory to gradually increase the striking force on the formed tube, causing the tense crystal lattice inside the formed tube to gradually relax, thereby releasing the stress inside the formed tube.

[0048] Please see the appendix Figure 6 The striking element 32 includes an elastic plate 321 and a magnet 322; The first end of the elastic plate 321 is fixedly connected to the conveying surface of the conveying assembly 1, and the magnet 322 is fixedly disposed at the second end of the elastic plate 321 and located on the side of the elastic plate 321 close to the fixing member 31.

[0049] The second end of the elastic plate 321 is also provided with a limiting component 33, which includes a limiting post 331 and a ball 332; The ball bearing 332 can prevent the magnet 322 from directly contacting the adsorption component 34 or the fixing component 31, thereby reducing friction.

[0050] The limiting post 331 is fixedly installed at the second end of the elastic plate 321 and is located on the side of the elastic plate 321 close to the fixing member 31; The ball 332 is located at the end of the limiting post 331, and the ball 332 is higher than the preset height of the upper surface of the magnet 322.

[0051] When the magnet 322 on the elastic plate 321 is affected by the adsorption member 34, the elastic plate 321 will bend towards the side where the adsorption member 34 is located until the ball 332 contacts the fixing member 31 or the adsorption member 34 and stops. When the striking member 32 is driven by the conveying component 1 to move in the preset direction, when the magnet 322 moves between the two adsorption members 34, the attractive force on the magnet 322 decreases, and the elastic plate 321 will rebound under its own elastic force and hit the forming tube, thus achieving the knocking effect.

[0052] Please see the appendix Figure 4 The fastener 31 extends along the second preset direction, and the first preset direction and the second preset direction have an angle between them; The distance between the fixing member 31 and the conveying assembly 1 gradually increases from the end closer to the profile extrusion die to the end farther away from the profile extrusion die.

[0053] There are multiple adsorption elements 34, which are arranged sequentially at intervals along the length of the fixing element 31. Each adsorption element 34 is another magnet that attracts the magnet 322.

[0054] refer to Figure 4 When the striking member 32 at the back is moved in the first preset direction, it will be attracted by the first adsorption member 34, causing the elastic plate 321 to bend. As the corresponding magnet 322 moves between the two adsorption members 34, the elastic plate 321 will rebound and hit the forming tube due to the decrease in attraction. As the striking member 32 moves in the first preset direction, the elastic plate 321 will oscillate after being struck. During the oscillation, when it approaches a new adsorption member 34, it will be attracted and further bend the elastic plate 321 for the next strike. As the distance between the fixing member 31 and the conveying component 1 gradually increases, the elastic plate 321 will be attracted by the adsorption member 34, and the degree of bending of the elastic plate 321 when attracted will gradually increase, thereby gradually increasing the striking force.

[0055] Please see the appendix Figure 7 The striking element 32 also includes an elastic pad 323, which is fixedly disposed at the second end of the elastic plate 321 and located on the side of the elastic plate 321 away from the fixing element 31.

[0056] The elastic pad 323 is a hollow airbag with an exhaust port, and multiple heat-conducting strips are provided on the side of the airbag away from the elastic plate.

[0057] When the elastic plate 321 strikes the formed tube, the elastic pad 323 impacts the formed tube, cushioning the impact and preventing deformation of the formed tube due to rigid impact. At the same time, the heat-conducting strip comes into contact with the formed tube during impact, transferring the heat of the formed tube to the air inside the elastic pad 323. When the elastic pad 323 is deformed by impact, it will squeeze out the air inside through the exhaust port and draw in new air, so that the heat-conducting strip can continuously conduct heat from the formed tube, thereby achieving a cooling effect and increasing the hardness of the impact point.

[0058] Example 4: Based on Example 1, the present invention provides an extrusion device: Please see the appendix Figure 2 An extrusion device includes a housing 4, a profile extrusion die 5, and a support mechanism. The profile extrusion die 5 includes an output end 51. The profile extrusion die 5 is set inside the housing 4 and is used to extrude and output shaped pipes. The extrusion device is also equipped with an extrusion module, which is used to cooperate with the profile extrusion die 5 to perform extrusion molding. The support mechanism is located at the output end 51 of the profile extrusion die 5, and the support mechanism is used to support the formed tube.

[0059] The extrusion device feeds the forming blank into the extrusion die, and through the extrusion module, the formed metal tube is extruded from the output end 51 of the extrusion die. The extruded tube is then processed to obtain the formed tube.

[0060] A guide support is provided at the output end 51 of the profile extrusion die 5.

[0061] The guide support has a hole in the middle that corresponds to the profile extrusion die 5. When the brushed aluminum alloy frame tube is torsionally deformed to obtain a spiral brushed structure, the guide support will directly bear the torsional force on the aluminum alloy frame tube. The guide support plays a role in dispersing the torsional force on the profile extrusion die 5, avoiding local stress concentration that could lead to microstructural deformation of the profile extrusion die 5, and preventing the microstructure on the surface of the profile extrusion die 5 from undergoing minor deformation or wear under continuous stress due to torsional force, thereby affecting its original precise dimensional accuracy and surface roughness.

[0062] Please see the appendix Figure 1 and 8 A feeding mechanism 6 is fixedly installed on the housing 4. The feeding mechanism 6 includes a feeding plate 61, and the output port of the feeding plate 61 is engaged with the input end of the profile extrusion die 5.

[0063] The feed plate 61 includes a first plate and a second plate spaced apart along the feeding direction; The feeding mechanism 6 also includes a pushing component 62, which includes a telescopic rod 621 and a V-shaped plate 622. The telescopic rod 621 is fixedly connected to the housing 4, and the telescopic end of the telescopic rod 621 is fixedly connected to the V-shaped plate 622. The V-shaped plate 622 is located between the first plate and the second plate, and can extend and retract with the telescopic rod 621 to protrude or recess relative to the second plate.

[0064] By feeding the preform into the first plate of the feed plate 61, the preform rolls to the top of the V-shaped plate 622. When feeding is required, the telescopic rod 621 extends through the V-shaped plate 622 to lift the preform between the extrusion module and the profile extrusion die 5. The extrusion module then squeezes the preform into the profile extrusion die 5 and performs extrusion molding. Example 5

[0065] This invention provides a method for extruding aluminum alloy patterned tubes: Please see Figure 9 and 10 A method for extruding patterned aluminum alloy tubes, comprising: S1, feeding, feeding the aluminum alloy bar into the profile extrusion die 5; S2, Extrusion molding, aluminum alloy bars are extruded into tubular components through the profile extrusion module; S3, Material conveying: The formed pipe is conveyed along the first preset direction under the support of the support mechanism.

[0066] The support mechanism also includes a striking component 3. Material conveying includes: S301, the formed tube is supported on multiple support components 2; S302, the conveying component 1 drives the forming tube to move along the first preset direction, and the striking component 3 strikes the forming tube.

[0067] Using ultrafine powders of H13 steel mold steel with a particle size of 1-100μm, or ultrafine powders of high-temperature alloys such as titanium alloys or nickel-based alloys, a surface layer with a surface roughness of Ra10-30μm and a thickness of 0.2-0.5mm is 3D printed on the inner surface of the exit area of ​​the hot extrusion die using the powder spreading method.

[0068] The aluminum alloy rod is then placed into the feed plate 61. The feed mechanism 6 feeds the aluminum alloy rod between the profile extrusion die and the extrusion module. The aluminum alloy rod is extruded by the profile extrusion module. The surface of the formed aluminum alloy frame tube has countless micro-scale straight grooves or countless parallel spiral grooves. The extruded aluminum alloy frame is extruded from the output end of the profile extrusion die of the extrusion device. The formed tube is transported along the first preset direction under the support of the support mechanism. Multiple support components 2 support the formed tube, so that one end of the frame is located inside the guide support component 5. The other end of the aluminum alloy frame is fixed by the torsion device and then torsion deformed. The maximum torsion angle is 20-45°. This torsion deformation causes the frame tube to work harden and eliminates anisotropy. Then the torsion aluminum alloy frame is removed from the top of the support mechanism, and the head and tail materials are cut off to complete the forming of the aluminum alloy wire drawing frame.

[0069] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
