[0002] Aluminum alloy bars are widely used in a wide range of fields, including aerospace, automotive manufacturing, and electronic equipment, due to their low density, high strength, and corrosion resistance. The processing of aluminum alloy bars typically involves multiple steps, including cutting, grinding, and surface treatment.

[0003] Current processing devices, such as the spiral aluminum alloy bar processing device and method disclosed in Chinese Patent Publication No. "CN105344732A," often produce burrs during the final extrusion of the small aluminum alloy bar before pulling it out, leaving it unpolished. This can affect the quality of the finished product. Furthermore, the initial pulling process can easily cause the small aluminum alloy bar to bend to a certain degree, affecting the quality of the finished product. Accordingly, the present invention provides a processing device and method for aluminum alloy bars. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a processing device and a processing method for aluminum alloy bars.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A processing device and method for aluminum alloy bars, comprising a support frame and a base, wherein a bar extrusion piece is provided on one side of the top of the base, and the bar extrusion piece can be used to extrude incoming material into bars, and then extrude the bars into shape; A clamping and grinding piece that matches the discharge position of the rod extrusion piece is provided on the other side of the top of the base. The clamping and grinding piece consists of a pressing and grinding part and a clamping and grinding part. The pressing and grinding part is used to prevent the extruded aluminum alloy material from bending in the upper and lower positions and to simultaneously grind burrs on the upper and lower surfaces of the aluminum alloy material.

[0006] Preferably, the pressing and grinding part and the clamping and grinding part are connected by a simultaneous transmission component, which can drive the pressing and grinding part to clamp and grind the aluminum alloy material up and down while simultaneously driving the clamping and grinding part to clamp and prevent bending and grind burrs on the groove parts on the left and right sides of the aluminum alloy material.

[0007] Preferably, when the simultaneous interpretation component is started: The simultaneous transmission component first pushes the pressing and grinding part, and some parts of the clamping and grinding part slide downward while synchronously driving the clamping and grinding part to slide and clamp from both sides to the middle, which is used to synchronously prevent bending and limit the aluminum alloy material in four directions of up, down, left and right, as well as to grind burrs.

[0008] Preferably, four support columns for positioning and supporting the pressing and grinding part are provided on one side of the base, two support columns form a group, and a fixing frame for installing and fixing the simultaneous interpretation component is fixedly provided between each group of support columns.

[0009] Preferably, the bar extrusion piece consists of a feeding part and a forming part, wherein the feeding part and the forming part are directly connected, and the incoming material can be pressed into an aluminum alloy bar, and then the aluminum alloy bar can be directly extruded and cooled to form.

[0010] Preferably, the clamping and grinding portion can simultaneously clamp and grind the grooves on both sides of the aluminum alloy material while the pressing and grinding portion presses and grinds the aluminum alloy material.

[0011] Preferably, the external pulling device can continuously pull out the aluminum alloy material extruded from the rod extrusion piece, and the pulled out aluminum alloy material passes through the clamping and polishing piece.

[0012] Preferably, two fixing plates are fixedly provided on one of the fixing frames.

[0013] Preferably, each of the four support columns is slidably connected with a slider.

[0014] A method for processing an aluminum alloy bar comprises the following steps: S1. Raw material preparation: Select appropriate aluminum alloy ingots, determine the alloy composition and grade according to the performance requirements of the required aluminum alloy bars, and inspect the aluminum alloy ingots to ensure that their chemical composition meets the standard requirements and there are no obvious defects such as pores and inclusions; S2. Melting and Casting: The aluminum alloy ingots that have passed the inspection are placed in a furnace for heating and melting. Appropriate amounts of refining agents and modifiers are added as needed to remove impurities, refine the grains, and improve the properties of the alloy. When the alloy liquid reaches the specified temperature and composition requirements, it is poured into a pre-prepared mold for casting to form a blank of the aluminum alloy bar; S3. Homogenization treatment: The aluminum alloy bar blank after casting is heated to a certain temperature and maintained for a period of time to fully homogenize the chemical composition of the alloy, eliminate the segregation phenomenon generated during the casting process, and improve the uniformity of the material's performance; S4, extrusion molding: the homogenized bar blank is heated to a suitable processing temperature range, and then plastically deformed through an extrusion device to achieve the desired size and shape; S5. Heat treatment: According to the final performance requirements of the aluminum alloy bar, the rolled or extruded bar is heat treated.

Common surface treatment methods include anodizing, chemical plating, electroplating and painting; S7. Machining: The surface-treated aluminum alloy bars are subjected to machining, such as cutting, drilling, turning, milling, etc., to obtain the required dimensional accuracy and surface quality; S8. Inspection and packaging: The processed aluminum alloy bars are comprehensively inspected, including dimensional accuracy, shape tolerance, mechanical properties, surface quality and other aspects. The aluminum alloy bars that pass the inspection are packaged. The packaging method is usually selected according to the size, quantity and transportation requirements of the bars, and the bars must be protected from damage and corrosion during transportation and storage. The present invention has the following beneficial effects: 1. By installing a clamping and grinding unit, the pressure-grinding portion of the clamping and grinding unit applies bending prevention and positioning to the aluminum alloy material in the upper and lower directions, while simultaneously grinding away burrs on the upper and lower sides. The clamping and grinding unit clamps the left and right grooves of the aluminum alloy material to prevent bending and grind away burrs, achieving simultaneous bending prevention and positioning, as well as burr grinding, for the aluminum alloy bar in all four directions. This comprehensive processing method effectively prevents bending and deformation of the aluminum alloy bar during processing, while simultaneously removing surface burrs, significantly improving the dimensional accuracy and surface quality of the aluminum alloy bar, meeting high-precision processing requirements.

[0015] 2. By setting up a simultaneous transmission component, when activated, it can push the pressing and grinding part to prevent bending and limit the aluminum alloy material in the upper and lower directions and grind burrs on the upper and lower surfaces. At the same time, it drives the clamping and grinding part to slide from the sides to the center, clamping and preventing bending and grinding burrs on the left and right grooves of the aluminum alloy material. This achieves simultaneous anti-bending and grinding of burrs in the four directions of the aluminum alloy material. This multi-directional collaborative processing method eliminates the need for multiple separate drive systems to control processing actions in different directions, simplifies the equipment structure, and reduces equipment costs and maintenance difficulties.

[0016] 3. By installing a bar extrusion unit and directly connecting its feed section with the forming section, incoming material can be quickly pressed into aluminum alloy bars and then extruded and cooled to form. External traction equipment continuously pulls the extruded aluminum alloy material out for simultaneous processing via the clamping and grinding unit. The entire processing flow is seamless, reducing waiting time in intermediate links. The simultaneous operation of the pressing and grinding sections and the clamping and grinding sections through simultaneous transmission components eliminates the need for separate operations when performing multi-directional processing of aluminum alloy materials. This significantly improves processing efficiency, shortens production cycles, and facilitates mass production. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1:

[0020] Reference Figures 1-4 A processing device and method for aluminum alloy bars, comprising a support frame 1 and a base 2. A bar extrusion piece is provided on one side of the top of the base 2. The bar extrusion piece can extrude the incoming material into bars, and then extrude the bars into shape. A clamping and grinding part matching the discharge position of the rod extrusion part is provided on the other side of the top of the base 2. The clamping and grinding part consists of a pressing and grinding part and a clamping and grinding part. The pressing and grinding part is used to prevent the extruded aluminum alloy material from bending in the upper and lower positions and to simultaneously grind burrs on the upper and lower surfaces of the aluminum alloy material.

[0021] The bar extrusion part consists of a feeding part and a forming part, wherein the feeding part and the forming part are directly connected, and the incoming material can be pressed into an aluminum alloy bar, and then the aluminum alloy bar can be directly extruded and cooled to form.

[0022] The external traction equipment can continuously pull out the aluminum alloy material extruded from the rod extrusion piece, and the pulled out aluminum alloy material passes through the clamping and polishing piece.

[0023] In this embodiment, if Figures 1-4 As shown, the rod extrusion part can specifically adopt the following structure: The rod extrusion component consists of a driving motor 3, a first mounting frame 4, a second mounting frame 5, a rod extrusion barrel 6, a feed port 7, a rotating rod 8, a feeding paddle 9, a cooling forming tube 10 and a discharge port 11, wherein the driving motor 3 is fixedly arranged on one side of the top of the base 2, the rod extrusion barrel 6 is fixedly arranged on the first mounting frame 4 and the second mounting frame 5, the feeding port 7 is fixedly arranged on the top of the rod extrusion barrel 6, the rotating rod 8 is rotatably connected to one side of the rod extrusion barrel 6, and is fixedly connected to the driving end of the driving motor 3, the feeding paddle 9 is rotatably arranged inside the rod extrusion barrel 6, and is fixedly connected to the rotating rod 8, the cooling forming tube 10 is fixedly arranged on the other side of the rod extrusion barrel 6, and the discharge port 11 opened inside it is connected to the rod extrusion barrel 6. When the driving motor 3 is started, the incoming material fed from the feeding port 7 is first pressed into an aluminum alloy bar through the feeding paddle 9 inside the rod extrusion barrel 6, and then the bar is extruded through the cooling forming tube 10 by spiral extrusion force.

[0024] Furthermore, the bar forming part can rapidly press incoming material into aluminum alloy bars and then extrude and cool them into shape. External pulling equipment continuously pulls the extruded aluminum alloy material out for simultaneous processing via clamping and grinding. The entire process is seamless, reducing waiting time in intermediate links. The simultaneous operation of the pressing and grinding sections and the clamping and grinding sections via simultaneous transmission components eliminates the need for separate steps when performing multi-faceted processing of aluminum alloy materials. This significantly improves processing efficiency, shortens production cycles, and facilitates mass production. Example 2:

[0025] In this embodiment, the pressing and grinding part and the clamping and grinding part are connected by a simultaneous transmission component. The simultaneous transmission component can drive the pressing and grinding part to clamp and grind the aluminum alloy material up and down while simultaneously driving the clamping and grinding part to clamp and prevent bending and grind burrs on the groove parts on the left and right sides of the aluminum alloy material.

[0026] When the simultaneous transmission component is started, the simultaneous transmission component first pushes the pressing and grinding part, and some parts of the clamping and grinding part slide downward while synchronously driving the clamping and grinding part to slide and clamp from both sides to the middle, which is used to synchronously prevent bending and limit the aluminum alloy material in four directions of up, down, left and right, and to grind burrs.

[0027] Four support columns 13 for positioning and supporting the pressing and grinding part are provided on one side of the base 2. Two support columns 13 form a group, and a fixing frame 12 for installing and fixing the simultaneous interpretation component is fixedly provided between each group of support columns 13.

[0028] Two fixing plates 26 are fixedly mounted on one of the fixing frames 12 , and sliders 14 are slidably connected to the four supporting columns 13 .

[0029] Specifically, refer to Figure 5-Figure 9 , the clamping and grinding assembly can adopt the following specific structure: The clamping and grinding assembly consists of a pressing and grinding part and a clamping and grinding part. The pressing and grinding part is composed of four support columns 13 to form a basic base. An upper pressure plate 15 is fixedly connected between the four sliders 14. Two first tooth plates 16 are fixedly connected to the top of the upper pressure plate 15. A lower support plate 17 is fixedly provided between the two groups of support columns 13 and at the top of the base 2.

[0030] Further, such as Figure 6 As shown, the upper pressing plate 15 can slide up and down along the supporting column 13 through the slider 14 and cooperate with the lower pressing plate 17 to clamp and grind the aluminum alloy material from top to bottom.

[0031] The grinding part is composed of two fixed frames 12 to form a basic base. The tops of the two fixed frames 12 are fixedly connected to support plates 18. The corresponding sides of the two support plates 18 are rotatably connected to threaded rods 19. Nuts 20 are threadedly sleeved on the two threaded rods 19. Two guide rods 21 are slidably connected on both sides of the two support plates 18. A grinding plate 22 is fixedly connected to one side of the two guide rods 21 and the nuts 20. The side of the support plate 18 away from the threaded rod 19 is rotatably connected to a first gear 23 fixedly connected to the threaded rod 19. Both sides of the upper pressure plate 15 are fixedly connected to a sliding frame 24. A second tooth plate 25 is fixedly provided on the inner wall of one side of the sliding frame 24. The second tooth plate 25 and the first gear 23 are meshed with each other.

[0032] Further, such as Figure 8 As shown, the sliding frame 24 is sleeved on the outside of the first gear 23, so that when the sliding frame 24 slides, the first gear 23 can be driven to rotate through the second tooth plate 25, and then the threaded rod 19 can be driven to rotate. At this time, the nut 20 can push the clamping plate 22 to slide along the direction of the guide rod 21, so as to clamp and grind the aluminum alloy material.

[0033] Furthermore, by sliding the pressing part downward, the sliding frame 24 can be driven to slide by the sliding of the lower pressure plate 15. At this time, the sliding frame 24 can push the first gear 23 to rotate through the second tooth plate 25. At this time, the clamping part can be driven to move synchronously by the sliding of the pressing part. Example 3:

[0034] Reference Figure 6-Figure 9 In this embodiment, the simultaneous interpretation component can be implemented as follows: The simultaneous interpretation assembly consists of two fixed plates 26, a second gear 27, a third gear 28, a fourth gear 29 and a servo motor 30. The two fixed plates 26 are fixedly arranged on the top of one of the fixed frames 12. The second gear 27 is rotatably connected between the sides of the two fixed plates 26 that are close to each other, and the third gear 28 is rotatably connected between the other sides of the two fixed plates 26 that are close to each other. The second gear 27 and the third gear 28 are meshed with each other. The two sides of the two fixed plates 26 close to the third gear 28 are rotatably connected to the fourth gear 29 that is fixedly connected to the third gear 28. The two fourth gears 29 are respectively meshed with the two first gear plates 16. A servo motor 30 is fixedly arranged on one side of one of the fixed plates 26, and the drive end of the servo motor 30 is fixedly connected between the second gears 27.

[0035] In this embodiment, combining the technical contents of the first embodiment and the second embodiment, the simultaneous transmission component can drive the pressing and grinding part to move by starting the servo motor 30. The actual movement is as follows: The servo motor 30 drives the second gear 27 to rotate, and the rotation of the second gear 27 drives the third gear 28 to rotate, and the third gear 28 synchronously drives the two fourth gears 29 to rotate. At this time, the two fourth gears 29 push the two first tooth plates 16 to drive the upper pressure plate 15 to slide along the support column 13, and then the clamping grinding part can be synchronously driven to move through the pressing grinding part.

[0036] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
