Description

Technical Field

[0001] This utility model relates to the field of aluminum profile extrusion technology, and more specifically, to an aluminum profile extrusion machine. Background Technology

[0002] Aluminum profiles are widely used in construction, transportation, electronics, machinery, and home decoration due to their advantages such as light weight, high strength, corrosion resistance, and ease of processing. Extrusion molding is the most important process for producing aluminum profiles, and the aluminum profile extrusion press is the core equipment for realizing this process.

[0003] Currently, common aluminum profile extrusion presses on the market mainly consist of a main unit (including a main cylinder and extrusion rod), an extrusion cylinder, a die, a heating system, a feeding mechanism, and a control system. The basic workflow is as follows: aluminum ingots heated to a plastic state are placed into the extrusion cylinder. The main cylinder drives the extrusion rod forward, forcing the aluminum material through a die with a specific cavity under immense pressure, thus continuously extruding profiles of the desired cross-sectional shape. However, in actual production applications, existing aluminum profile extrusion presses still have some shortcomings that urgently need improvement. Existing structures typically only apply pressure from the front (axial) side of the die, lacking effective active constraint on the sides. Under high extrusion pressure (especially when extruding flat, wide profiles or hard alloys with large aspect ratios), the sidewalls of the die are subjected to a large lateral force from the aluminum material, resulting in slight elastic or even plastic deformation, causing a slight expansion of the die orifice at the working zone. Utility Model Content

[0004] Based on this, in order to solve the problem of the lack of effective active constraint or extrusion on the side of the mold, this utility model provides an aluminum profile extrusion press, the specific technical solution of which is as follows: An aluminum profile extrusion press includes a feeding assembly and an extrusion assembly. The feeding assembly includes a feeding trough and a feeding cylinder. The feeding trough has a feeding channel. A feeding plate is driven to the output end of the feeding cylinder. The feeding plate has a feeding head that fits into the feeding channel. The outer surface of the feeding cylinder is coated with a ceramic coating. The extrusion assembly includes an axial extrusion head, a rotatably arranged extrusion groove, and two lateral extrusion heads respectively located on both sides of the extrusion groove. The axial extrusion head is located above the extrusion groove and can be raised and lowered relative to the extrusion groove. An extrusion channel is formed on the axial extrusion head. A receiving channel for communicating with the feeding channel is formed on the extrusion groove. An extrusion space is formed between the extrusion channel and the receiving channel.

[0005] The aforementioned aluminum profile extrusion press, by setting a rotatable extrusion groove and cooperating with an axial extrusion head and two lateral extrusion heads to apply pressure synchronously or sequentially in multiple directions, allows the aluminum material to flow and fill simultaneously or as needed from the axial direction and two lateral directions within the extrusion space. This makes it possible to directly extrude profiles with complex lateral features (such as lateral lugs, asymmetrical branches, and internal cavities) in a single operation. This avoids the cumbersome process of first extruding simple profiles and then performing secondary machining in traditional processes. It not only saves materials and reduces processing losses, but also ensures the continuity of the overall streamline structure and mechanical properties of the profile, significantly improving the overall strength and structural integrity of the product. In addition, the ceramic coating covering the outer surface of the cylinder housing provides wear resistance, corrosion resistance, non-stick properties, high hardness, and high temperature resistance.

[0006] Furthermore, the feeding assembly also includes a feeding frame, the feeding trough and the feeding cylinder are both mounted on the feeding frame, and both sides of the feeding plate are provided with sliders that can slide relative to the feeding frame. A sliding gap is formed between the sliders and the feeding head, and the sliding gap is adapted to the wall of the feeding trough.

[0007] Furthermore, a cylinder cover is installed at the end of the feeding cylinder, and a piston rod that is connected to the feeding plate is opened in the middle of the cylinder cover. A sealing ring is installed on the outside of the piston rod, and a nickel-based alloy coating is provided on the outer surface of the sealing ring. A nut body is installed on the outside of the nickel-based alloy coating.

[0008] Furthermore, the inner surface of the feeding cylinder is coated with a nano-coating.

[0009] Furthermore, the extrusion assembly also includes an extrusion frame and a locking cylinder. The extrusion groove is rotatably mounted on the extrusion frame via a rotating gear installed at the bottom. The rotating gear has a locking hole. The locking cylinder is installed at the bottom of the extrusion frame, and a locking rod corresponding to the locking hole is drivenly connected to the output end of the locking cylinder.

[0010] Furthermore, the extrusion assembly also includes an axial pressure cylinder and two side pressure cylinders. The axial pressure cylinder is mounted on the top of the extrusion frame, and its output end is connected to the axial extrusion head. The two side pressure cylinders are respectively mounted on both sides of the extrusion frame, and the output end of each side pressure cylinder is connected to the lateral extrusion head.

[0011] Furthermore, a cooling chamber is formed inside the axial extrusion head, the cooling chamber is connected to the extrusion channel, and a plurality of water spray holes are evenly opened inside the cooling chamber. A water inlet conduit connected to the water spray holes is connected to the outer wall of the axial extrusion head.

[0012] Furthermore, a high-temperature resistant plate is laid on the end of the lateral extrusion head that abuts against the aluminum ingot. A layer of carbon fiber felt is provided on one side surface of the high-temperature resistant plate, and a high-temperature resistant film layer is provided between the carbon fiber felt and the high-temperature resistant plate.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0021] like Figure 1 and Figure 2 As shown, an aluminum profile extrusion press according to one embodiment of the present invention includes a feeding assembly and an extrusion assembly. The feeding assembly includes a feeding trough 1 and a feeding cylinder 2. The feeding trough 1 has a feeding channel 1. The output end of the feeding cylinder 2 is connected to a feeding plate 3. The feeding plate 3 is provided with a feeding head 31 that fits into the feeding channel 1. The outer surface of the feeding cylinder 2 is coated with a ceramic coating. The extrusion assembly includes an axial extrusion head 4, a rotatably arranged extrusion groove 5, and two lateral extrusion heads 6 respectively provided on both sides of the extrusion groove 5. The axial extrusion head 4 is located above the extrusion groove 5 and can be raised and lowered relative to the extrusion groove 5. The axial extrusion head 4 has an extrusion channel 5. The extrusion groove 5 has a receiving channel for communicating with the feeding channel 1. An extrusion space is formed between the extrusion channel 5 and the receiving channel.

[0022] The aforementioned aluminum profile extrusion press, by setting a rotatable extrusion groove 5 and cooperating with an axial extrusion head 4 and two lateral extrusion heads 6 to apply pressure synchronously or sequentially in multiple directions, allows the aluminum material to flow and fill simultaneously or as needed from the axial direction and two lateral directions within the extrusion space. This makes it possible to directly extrude profiles with complex lateral features (such as lateral lugs, asymmetrical branches, and internal cavities) in a single process, avoiding the cumbersome process of first extruding simple profiles and then performing secondary machining in traditional processes. This not only saves materials and reduces processing losses, but also ensures the continuity of the overall streamline structure and mechanical properties of the profile, significantly improving the overall strength and structural integrity of the product. In addition, the ceramic coating covering the outer surface of the cylinder housing provides wear resistance, corrosion resistance, non-stick properties, high hardness, and high temperature resistance.

[0023] In one embodiment, the feeding assembly further includes a feeding frame, with the feeding trough 1 and feeding cylinder 2 both mounted on the feeding frame. The feeding plate 3 has sliding blocks protruding from both sides, allowing it to slide relative to the feeding frame. A sliding gap is formed between the sliding blocks and the feeding head 31, and this sliding gap is adapted to the wall of the feeding trough 1. The feeding plate 3, through the sliding blocks protruding from both sides, forms a bilateral guiding constraint structure with the feeding frame, effectively resisting the deflection torque and lateral force that may be generated during the feeding of the aluminum ingot. This prevents the feeding head 31 from getting stuck or tilting within the feeding trough 1, ensuring that the pushing action is executed with high precision along a preset straight trajectory, thus laying a reliable mechanical foundation for the accurate entry of the aluminum ingot into the extrusion station.

[0024] like Figure 3 As shown, in one embodiment, a cylinder head 21 is installed at the end of the feeding cylinder 2, and a piston rod 22, which is connected to the feeding plate 3, is provided in the middle of the cylinder head 21. A sealing ring is placed on the outside of the piston rod 22, and a nickel-based alloy coating is provided on the outer surface of the sealing ring. A nut body 23 is installed on the outside of the nickel-based alloy coating. The nickel-based alloy coating has excellent high temperature resistance, corrosion resistance, and high strength. It is sprayed on the upper and inner surfaces of the sealing ring by a supersonic cold spraying process to avoid thermal deformation of the sealing ring body and damage to the material structure, thus giving the sealing surface of the sealing ring excellent high temperature resistance, corrosion resistance, and high strength.

[0025] In one embodiment, the inner surface of the feeding cylinder 2 is coated with a nano-coating. This allows for the rapid formation of a thin, transparent protective film, resulting in a dense nano-coating. The nano-coating does not sacrifice protection, preventing wear on the piston rod 22, and also provides waterproofing, moisture resistance, dustproofing, oil resistance, and chemical corrosion protection.

[0026] like Figure 2 As shown, in one embodiment, the extrusion assembly further includes an extrusion frame and a locking cylinder 7. The extrusion groove 5 is rotatably mounted on the extrusion frame via a rotating gear installed at the bottom. The rotating gear has a locking hole. The locking cylinder 7 is installed at the bottom of the extrusion frame, and a locking rod corresponding to the locking hole is driven to the output end of the locking cylinder 7. The locking cylinder 7 precisely inserts the locking rod into the locking hole on the rotating gear, achieving rigid mechanical positioning and locking of the extrusion groove 5 in the circumferential direction. This ensures that after each rotation, the relative position between the extrusion groove 5 (and its receiving channel) and the axial extrusion head 4 and the lateral extrusion head 6 has extremely high repeatability, providing a reliable workstation reference for producing complex profile features in different directions.

[0027] Specifically, the rotating gear is driven by a rotary motor.

[0028] In one embodiment, the extrusion assembly further includes an axial pressure cylinder and two side pressure cylinders. The axial pressure cylinder is mounted on the top of the extrusion frame and its output end is drivenly connected to the axial extrusion head 4. The two side pressure cylinders are respectively mounted on both sides of the extrusion frame, and the output end of each side pressure cylinder is drivenly connected to the side extrusion head 6.

[0029] like Figure 1 and Figure 2 As shown, in one embodiment, a cooling chamber is formed inside the axial extrusion head 4, which is connected to the extrusion groove 5. Multiple water spray holes are uniformly arranged inside the cooling chamber, and a water inlet conduit 41 connected to the water spray holes is attached to the outer wall of the axial extrusion head 4. This allows the cooling medium (water or atomized gas-liquid mixture) to be directly and uniformly sprayed onto the surface of the aluminum ingot immediately after the profile is extruded, achieving direct quenching of the extruded profile and enabling it to quickly pass through the critical temperature range to obtain a non-equilibrium supersaturated solid solution structure.

[0030] like Figure 4 As shown, in one embodiment, a high-temperature resistant plate 61 is laid on the end of the lateral extrusion head 6 that abuts against the aluminum ingot. A layer of carbon fiber felt 62 is provided on one side surface of the high-temperature resistant plate 61, and a high-temperature resistant film layer 63 is provided between the carbon fiber felt 62 and the high-temperature resistant plate 61. A high-temperature resistant coating layer 64 is coated on the other side of the high-temperature resistant plate 61. By using carbon fiber felt 62, high-temperature resistant film, and high-temperature resistant coating, the overall high-temperature resistance of the fiberboard can be improved, making it safe and reliable to use.

[0031] Specifically, the high-temperature resistant film layer 63 is adhered to the high-temperature resistant plate 61 by a high-temperature resistant adhesive.

[0032] In one embodiment, the high-temperature resistant film layer 63 is adhered to the high-temperature resistant plate 61 by a high-temperature resistant adhesive.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, the aluminum profile extrusion press further includes a discharge assembly, which includes a discharge rack and a discharge trough 8 installed on the discharge rack. The discharge trough 8 has a discharge channel 8 for communicating with the receiving channel, and the discharge channel 8 is inclined.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
