Description

Technical Field

[0001] This invention relates to the field of extrusion equipment technology, and in particular to an aluminum alloy extrusion forming apparatus that is easy to position. Background Technology

[0002] Aluminum alloy extrusion molding is one of the important methods of metal plastic processing. Its core principle is to use the driving force of the extrusion device to make the aluminum alloy ingot in a plastic state undergo plastic deformation under the constraint of the mold cavity, and finally form an aluminum alloy profile or part that matches the shape of the mold cavity.

[0003] Aluminum alloy extruded products, with their excellent properties such as lightweight, high strength, corrosion resistance, and ease of processing, have been widely used in various fields including construction, transportation, aerospace, and electronics. In the construction industry, extruded aluminum alloy profiles are used to manufacture door and window frames, curtain wall framing, and stair railings, combining aesthetics with structural stability. In the transportation industry, aluminum alloy extruded products are widely used in high-speed rail body profiles, automobile door frames and structural components, and ship deck profiles, effectively reducing vehicle weight and improving fuel economy. In the aerospace industry, high-precision aluminum alloy extruded parts have become important components of key structures such as aircraft wings and fuselage frames, placing extremely high demands on the dimensional accuracy and mechanical properties of the products.

[0004] Chinese Patent Publication No. CN211161246U discloses an extrusion forming apparatus for aluminum alloy profiles, including a first support frame, a worktable on the upper side of the first support frame, a lower die base on the worktable, a second support frame on the upper side of the worktable, a cylinder assembly on the upper side of the second support frame, a control switch on the second support frame, a plurality of push rods on the cylinder assembly, each push rod being detachably connected to an upper die, a base plate on the lower side of the first support frame, a first hinge seat on the base plate, a first rotating rod on the first hinge seat, the middle of the first rotating rod being rotatably connected to the first hinge seat, a strip groove on one side of the first rotating rod, a foot pedal on the other side of the first rotating rod, a movable die on the lower die base, a connecting rod fixedly connected to the lower side of the movable die, a second hinge seat on the lower side of the connecting rod, a second rotating rod on the second hinge seat, the second rotating rod passing through the strip groove and rotatably connected to the second hinge seat, and a connecting boss on the first support frame, the connecting boss having a positioning groove.

[0005] However, the above-mentioned device lacks a corresponding support structure during operation. During long-term extrusion production, the connecting parts suffer severe wear. Furthermore, the device relies solely on the positioning slide and limiting linkage, without fixing the mold itself, making the mold prone to displacement during extrusion. Summary of the Invention

Limiting components for ensuring that the position of the fixed mold assembly does not deviate are provided on the left and right sides of the moving mold assembly. A feeding assembly for removing aluminum alloy ingots is provided on the front side of the upper part of the extrusion table.

[0009] Preferably, the feeding assembly includes a circular roller rotatably mounted on the front side of the upper end of the extrusion table, and the lower side of the outer surface of the circular roller is connected to a rotating shaft. A circular box is fixedly mounted on the upper end of the circular roller. A circular ring plate is provided on the upper side of the outer surface of the circular box, and the lower end of the circular ring plate is slidably connected to the upper end of the extrusion table. A limit roller is fixedly mounted on one side of the upper end of the circular ring plate. A torsion spring is provided on the inner surface of the circular box. A fixed roller is fixedly mounted on the center of the spiral of the torsion spring, and the end of the torsion spring away from the fixed roller is fixedly connected to the inner surface of the circular box. The lower end of the fixed roller is fixedly connected to the upper end of the extrusion table.

[0010] Preferably, the feeding assembly further includes a swing rod rotatably mounted on the front side of the upper end of the extrusion table. The upper end of the swing rod has a slot, and the inner surface of the slot is slidably connected to the inner surface of the limiting roller. An auxiliary positioning laser positioner is fixedly mounted on the upper right side of the swing rod, and a clamping mechanism for clamping aluminum alloy ingots is fixedly mounted on the right end of the swing rod below the laser positioner.

[0011] Preferably, the fixed mold assembly includes a rotating shaft disposed on the front sidewall of the inner surface of the operating groove, and two fixed molds are fixedly installed at the rear end of the rotating shaft. Rectangular grooves are opened at the left and right ends of the two fixed molds, and mold chambers are opened at the ends of the two fixed molds that are far apart from each other.

[0012] Preferably, the moving mold assembly includes a drive seat fixedly installed at the lower middle part of the protective cover, a push rod is provided at the lower middle part of the drive seat, a rectangular seat is fixedly installed at the lower end of the push rod, and a moving mold is fixedly installed at the lower middle part of the rectangular seat.

[0013] Preferably, the left and right walls of the inner surface of the operating groove are provided with limit grooves, and the left and right sides of the upper end of the extrusion table are fixedly installed with guide rails for guidance.

[0014] Preferably, the support assembly includes two L-shaped rollers fixedly installed at the left end of the rectangular base, and rollers are rotatably installed at the lower ends of the vertical portions of the two L-shaped rollers.

[0015] Preferably, the support assembly further includes a plurality of springs fixedly connected to the left side wall of the inner surface of the limiting groove, a wedge block is fixedly installed on the right end of the plurality of springs, an inclined plate for limiting the falling aluminum alloy finished product is fixedly installed on the upper side of the right end of the wedge block, and an inclined guide block for guiding the aluminum alloy finished product to be unloaded is fixedly installed in the middle of the bottom wall of the inner surface of the operating groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention utilizes a torsion spring for energy storage. After the rotating shaft finishes its operation, it works in conjunction with a swing rod, laser positioner, and clamping mechanism to convert the rotational power into the swinging power of the swing rod, enabling convenient and direct positioning and feeding. When the moving mold descends and extrudes, the wedge block automatically presses against the lower end of the fixed mold, preventing stress at the connection between the rotating shaft and the fixed mold. This avoids deformation or breakage of the connection due to long-term extrusion, extending the service life of the fixed mold assembly. Simultaneously, the U-shaped roller and L-shaped block are guided by the inclined groove of the sliding groove, allowing the L-shaped block to engage with the rectangular groove of the fixed mold, locking the fixed mold position from both sides. This prevents the fixed mold from shifting horizontally during extrusion, ensuring the dimensional accuracy of the extruded parts.

[0019] 2. This invention uses a rotating shaft to drive the fixed mold to rotate half a turn, switching the upper fixed mold to the lower side. The finished product leaves the mold cavity by its own gravity. At the same time, with the help of the inclined plate and inclined guide block, automated material feeding is achieved, improving production efficiency. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figure 1 and Figure 2 As shown, an aluminum alloy extrusion forming device for easy positioning includes an extrusion table 1 and a protective cover 11 disposed on the upper end of the extrusion table 1 to protect the internal structure. An operating groove is provided in the middle of the upper end of the extrusion table 1. A fixed mold assembly 2 is provided on the front side wall of the inner surface of the operating groove in the middle of the upper end of the extrusion table 1. The fixed mold assembly 2 includes a rotating shaft 22. A moving mold assembly 3 is fixedly installed in the middle of the lower end of the protective cover 11. The moving mold assembly 3 cooperates with the fixed mold assembly 2 to extrude the aluminum alloy ingot and form it into a specific shape. Supporting components 4 for supporting the fixed mold assembly 2 during the extrusion process are provided on the left and right sides of the moving mold assembly 3. Limiting components 5 for ensuring that the position of the fixed mold assembly 2 does not deviate are provided on the left and right sides of the moving mold assembly 3. A feeding component 6 for removing the aluminum alloy ingot is provided on the front side of the upper end of the extrusion table 1.

[0032] When extruding aluminum alloy ingots to form finished aluminum alloy products, the aluminum alloy ingots to be extruded are transported to the front side of the upper end of the extrusion table 1 using an intermittent conveying device in the prior art, in preparation for removal and extrusion molding.

[0033] like Figure 8 and Figure 9The feeding assembly 6 includes a circular roller 61 rotatably mounted on the front side of the upper end of the extrusion table 1, and the lower side of the outer surface of the circular roller 61 is connected to the rotating shaft 22. A circular box 66 is fixedly mounted on the upper end of the circular roller 61. A circular ring plate 65 is provided on the upper side of the outer surface of the circular box 66, and the lower end of the circular ring plate 65 is slidably connected to the upper end of the extrusion table 1. A limit roller 651 is fixedly mounted on one side of the upper end of the circular ring plate 65. A torsion spring 67 is provided on the inner surface of the circular box 66. A fixed roller 68 is fixedly mounted on the spiral center of the torsion spring 67, and the end of the torsion spring 67 away from the fixed roller 68 is fixedly connected to the inner surface of the circular box 66. The lower end of the fixed roller 68 is fixedly connected to the upper end of the extrusion table 1.

[0034] It should be noted that the lower outer surface of the roller 61 and the outer surface of the rotating shaft 22 are connected by a belt pulley transmission device and a bevel gear transmission group. When the rotating shaft 22 rotates half a turn, the roller 61 can rotate three turns.

[0035] In addition, the upper end of the outer surface of the circular box 66 is rotatably connected to the inner surface of the circular ring plate 65 through a one-way rotating shaft two, and a one-way rotating shaft one is provided between the outer surface of the circular roller 61 and the bevel gear that is fixedly connected.

[0036] It should also be noted that after the fixed roller 68 passes through the upper end of the circular roller 61 and extends to the upper end of the extrusion table 1, the fixed roller 68 is fixedly connected to the extrusion table 1.

[0037] Specifically, when preparing to extrude aluminum alloy finished products, the rotating shaft 22 rotates half a turn, and then drives the circular roller 61 to rotate three turns through the belt pulley transmission device, bevel gear transmission group and one-way rotating shaft. At this time, during the rotation of the circular roller 61, the end of the circular box 66 and the torsion spring 67 away from the fixed roller 68 rotates three turns. During the rotation of the circular box 66 and the torsion spring 67, energy is stored in the torsion spring 67.

[0038] Similarly, due to the one-way rotation shaft at the upper end of the outer surface of the circular box 66, the circular ring plate 65 does not rotate when the circular box 66 drives the torsion spring 67 to rotate for energy storage.

[0039] Furthermore, after the rotating shaft 22 rotates half a turn, the rotating shaft 22 stops running. At this time, the roller 61 is no longer driven to rotate. Then, the energy-stored torsion spring 67 drives the round box 66 and the roller 61 to rotate in reverse. At this time, through the cooperation of the one-way rotating shaft, the bevel gear set will not run. At the same time, through the cooperation of the two-way rotating shaft, when the torsion spring 67 drives the round box 66 and the roller 61 to rotate in the opposite direction, the ring plate 65 is driven to rotate one turn.

[0040] That is, when the rotating shaft 22 rotates half a turn, it drives the roller 61 and the box 66 to rotate three turns, while storing energy in the torsion spring 67. Similarly, the energy stored in the torsion spring 67 pushes the box 66 and the ring plate 65 to rotate one turn.

[0041] Furthermore, when the annular plate 65 is driven to rotate one revolution, it drives the limiting roller 651 to rotate one revolution along the axis of the annular plate 65.

[0042] like Figure 9 The feeding assembly 6 also includes a swing rod 62 rotatably mounted on the front side of the upper end of the extrusion table 1. The upper end of the swing rod 62 has a slot 621, and the inner surface of the slot 621 is slidably connected to the inner surface of the limiting roller 651. A laser positioner 63 for auxiliary positioning is fixedly installed on the upper right side of the swing rod 62. A clamping mechanism 64 for clamping aluminum alloy ingots is fixedly installed on the right end of the swing rod 62 below the laser positioner 63.

[0043] It should be noted that the above-mentioned clamping mechanism 64 is a commonly used technical means in the prior art. It is only necessary to satisfy that the clamping mechanism 64 can clamp, fix and release aluminum alloy ingots. The specific structure and operating principle of the clamping mechanism 64 will not be described in detail in this solution.

[0044] Furthermore, it should be noted that the aforementioned laser positioner 63 consists of a laser emitter, a photoelectric receiver, a signal processing module, a power supply unit, and a mounting base. The laser emitter emits a laser beam toward the center of the mold cavity of the fixed mold 21. When the swing rod 62 drives the clamping mechanism 64 and the aluminum alloy ingot to approach the upper mold cavity of the fixed mold 21, the laser beam irradiates the central surface of the mold cavity and is reflected. The reflected light is received by the quadrant photocell of the photoelectric receiver. The signal processing module calculates the distance and offset between the aluminum alloy ingot and the center of the mold cavity of the fixed mold 21 based on the position of the light spot received by the photocell. When the offset is ≤0.1mm and the distance reaches the trigger threshold of 50mm, the signal processing module sends a release signal to the clamping mechanism 64 to achieve precise unloading of the aluminum alloy ingot.

[0045] Before extruding the aluminum alloy ingot, the aluminum alloy ingot to be extruded is conveyed to the clamping mechanism 64 below by an intermittent conveying device, and then the clamping mechanism 64 clamps and fixes the aluminum alloy ingot.

[0046] When the ring plate 65 drives the limiting roller 651 to rotate around the axis of the ring plate 65, it slides along the inner surface of the groove 621, and then through the cooperation of the limiting roller 651 and the groove 621, the swing rod 62 swings once.

[0047] During the swinging motion of the swing rod 62 toward the middle of the upper end of the extrusion table 1, the swing rod 62 drives the laser positioner 63, the clamping mechanism 64, and the aluminum alloy ingot that is clamped and fixed to turn toward the middle of the upper end of the extrusion table 1.

[0048] like Figure 4The fixed mold assembly 2 includes a rotating shaft 22 disposed on the front side wall of the inner surface of the operating groove. Two fixed molds 21 are fixedly installed at the rear end of the rotating shaft 22. Rectangular grooves 23 are provided at the left and right ends of the two fixed molds 21. Mold chambers are provided at the ends of the two fixed molds 21 that are far apart from each other.

[0049] It should be noted that the two fixed molds 21 are arranged symmetrically.

[0050] During the process of the swinging rod 62 swinging to drive the clamping mechanism 64, the clamped aluminum alloy ingot, and the laser positioner 63 to rotate towards the middle of the upper end of the extrusion table 1, the fixed mold 21 and the rotating shaft 22 are both in a stationary state, and the mold cavity at the upper end of the fixed mold 21 is in a horizontal state.

[0051] Then, when the right end of the swing rod 62 rotates to the middle of the upper end of the fixed mold 21, and the laser positioner 63 senses that the clamping mechanism 64 and the clamped aluminum alloy ingot are about to rotate to the middle of the upper end of the fixed mold 21, the laser positioner 63 transmits a signal, and the clamping mechanism 64 is activated, releasing the clamped aluminum alloy ingot, so that the aluminum alloy ingot falls to the middle of the inner surface of the upper mold cavity of the fixed mold 21, ready for extrusion molding. The laser positioner 63 cooperates with the upper mold cavity of the fixed mold 21 to facilitate the positioning and release of the aluminum alloy ingot to be used.

[0052] like Figure 5 The moving mold assembly 3 includes a drive seat 31 fixedly installed at the lower middle part of the protective cover 11. A push rod 34 is provided at the lower middle part of the drive seat 31. A rectangular seat 32 is fixedly installed at the lower end of the push rod 34. A moving mold 33 is fixedly installed at the lower middle part of the rectangular seat 32. During the extrusion of aluminum alloy ingots, the push rod 34 pushes the rectangular seat 32 and the moving mold 33 downwards, which cooperate with the fixed mold 21 located on the upper side to form the required aluminum alloy product.

[0053] The aforementioned push rod 34 is a commonly used technical means in the prior art. When the push rod 34 is activated, it can slowly push the rectangular seat 32 and the moving mold 33 downwards, and cooperate with the fixed mold 21 to extrude and form the aluminum alloy ingot inside the mold cavity at the upper end of the fixed mold 21.

[0054] like Figure 3 Limiting grooves 13 are provided on both the left and right walls of the inner surface of the operating groove.

[0055] like Figure 7 The support assembly 4 includes two L-shaped rollers 41 fixedly installed on the left end of the rectangular base 32, and rollers 42 are rotatably installed on the lower end of the vertical part of the two L-shaped rollers 41.

[0056] Furthermore, as the rectangular seat 32 is pushed down, it will drive the two L-shaped rollers 41 and the matching rollers 42 to descend synchronously.

[0057] like Figure 7 The support assembly 4 also includes several springs 45 fixedly connected to the left side wall of the inner surface of the limiting groove 13. A wedge block 43 is fixedly installed on the right end of the several springs 45. An inclined plate 44 for limiting the falling aluminum alloy finished product is fixedly installed on the upper side of the right end of the wedge block 43. An inclined guide block 46 for guiding the aluminum alloy finished product to be unloaded is fixedly installed in the middle of the bottom wall of the inner surface of the operating groove.

[0058] Furthermore, when the two L-shaped rollers 41 and the matching rollers 42 are driven down a certain distance by the rectangular seat 32, the lower side of the outer surface of the two rollers 42 contacts the upper end of the wedge block 43 on the same side. As the two L-shaped rollers 41 and the matching rollers 42 continue to be driven down by the rectangular seat 32, when the two rollers 42 descend, they cooperate with the inclined surface of the wedge block 43 to move the wedge block 43 to the right. At the same time as the wedge block 43 moves to the right, it will stretch several springs 45 on the same side.

[0059] Then, when the lower end of the moving mold 33 is aligned with the upper end of the fixed mold 21 located on the upper side, the roller 42 and the L-shaped roller 41 are driven to descend to the vertical part on the left side of the wedge block 43, at which point the upper end of the wedge block 43 is in close contact with the lower end of the fixed mold 21 located on the lower side.

[0060] By using two wedge blocks 43 to tightly support the lower end of the fixed mold 21 located on the lower side, it is ensured that when the moving mold 33 and the fixed mold 21 located on the upper side extrude aluminum alloy ingots, the connection between the rotating shaft 22 and the two fixed molds 21 is in a state of no force.

[0061] Then, the rectangular base 32 and the moving mold 33 are pushed downward by the lower end of the push rod 34. At this time, the inner surface of the lower end of the moving mold 33 cooperates with the upper mold cavity of the fixed mold 21 located on the upper side, and slowly squeezes the aluminum alloy ingot inside the upper mold cavity, so that the aluminum alloy ingot slowly extends and forms along the inner surface of the mold cavity.

[0062] At the same time, when the moving die 33 and the rectangular seat 32 are extruding aluminum alloy ingots, the L-shaped roller 41 and the matching roller 42 continue to descend along the vertical part on the left side of the wedge block 43 to ensure that the wedge block 43 always supports the fixed die 21 located on the lower side.

[0063] like Figure 6 The limiting component 5 includes a U-shaped roller 51 fixedly installed at the left end of the rectangular base 32.

[0064] Furthermore, when the push rod 34 is running and its lower end pushes the rectangular seat 32 and the moving die 33 downward in preparation for extrusion, the rectangular seat 32 will drive the U-shaped roller 51 to descend simultaneously.

[0065] like Figure 3 The upper left and right sides of the extrusion table 1 are fixedly installed with guide rails 12 for guidance.

[0066] like Figure 6 The limiting component 5 also includes an L-shaped block 52 that is slidably connected to the outer surface of the left guide rail 12. A sliding groove 54 is provided on the left side of the front end of the L-shaped block 52, and several springs 53 are fixedly installed on the left end of the L-shaped block 52.

[0067] The aforementioned sliding groove 54 is composed of two vertical grooves and one inclined groove, and the inclined groove connects the two vertical grooves.

[0068] Furthermore, during the process of the U-shaped roller 51 being driven to descend by the rectangular seat 32, the middle part of the outer surface of the horizontal portion of the U-shaped roller 51 enters the inner surface of the sliding groove 54 from the upper side of the inner surface of the sliding groove 54. As the U-shaped roller 51 continues to be driven to descend by the rectangular seat 32, the outer surface of the U-shaped roller 51 moves downward along the inner surface of the inclined groove of the sliding groove 54. Then, through the cooperation of the inclined groove portion of the sliding groove 54, the L-shaped block 52 moves to the right along the guide rail 12. At the same time, the L-shaped block 52 will stretch several springs 53 on the same side.

[0069] Then, the lower end of the push rod 34 pushes the rectangular seat 32 and the moving mold 33 so that the lower end of the moving mold 33 is aligned with the upper end of the fixed mold 21 located on the upper side. At this time, the right end of the horizontal part of the L-shaped block 52 moves to the right and is in close contact with the inner surface of the rectangular groove 23 located on the upper side, ensuring that the fixed mold 21 will not shift its position before the moving mold 33 and the mold cavity of the fixed mold 21 located on the upper side are engaged and squeezed.

[0070] Similarly, after the right end of the horizontal part of the L-shaped block 52 is in close contact with the inner surface of the matching rectangular groove 23, the moving mold 33 and the rectangular seat 32 are pushed down slowly by the push rod 34 to extrude the aluminum alloy ingot. At this time, the U-shaped roller 51 is driven by the rectangular seat 32 to continue to descend along the inner surface of the vertical groove of the sliding groove 54.

[0071] After the moving mold 33 and the upper mold cavity of the fixed mold 21 located on the upper side are extruded and formed, the lower end of the push rod 34 drives the rectangular seat 32 and the moving mold 33 to move upward. When the rectangular seat 32 moves upward, it will drive the U-shaped roller 51, the two L-shaped rollers 41 and the matching rollers 42 to move upward at the same time.

[0072] Furthermore, when the U-shaped roller 51 moves upward to the inner surface of the inclined groove of the sliding groove 54, the stretched spring 53 drives the L-shaped block 52 to move to the left along the guide rail 12, releasing the locking limit of the right end of the horizontal part of the L-shaped block 52 to the rectangular groove 23.

[0073] Similarly, when the two L-shaped rollers 41 and the matching rollers 42 are driven to move upward until the lower side of the outer surface of the rollers 42 begins to contact the inclined surface of the wedge block 43, the stretched spring 45 drives the wedge block 43 and the inclined plate 44 to move to the left, releasing the support of the fixed mold 21 located on the lower side.

[0074] After the rectangular base 32 and the moving mold 33 have moved upward and reset, the rotating shaft 22 is activated. Then, the rotating shaft 22 rotates half a turn, causing the fixed mold 21 located on the upper side to rotate downward. During the rotation of the fixed mold 21 located on the upper side, the aluminum alloy finished product in the mold cavity at the upper end of the fixed mold 21 will automatically fall due to its own weight. As the aluminum alloy finished product falls, it is blocked by the inclined plate 44, causing the aluminum alloy finished product to fall onto the inclined surface of the inclined guide block 46 and slide out of the extrusion table 1 along the inclined surface of the inclined guide block 46.

[0075] Similarly, after the rotating shaft 22 drives the two fixed molds 21 to rotate half a turn, the swing rod 62 swings through the cooperation of the round roller 61, the round box 66 and the torsion spring 67 to drive the clamping mechanism 64 to release the clamped aluminum alloy ingot into the mold cavity at the upper end of the new fixed mold 21, ready for the next extrusion.

[0076] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
