Description

Technical Field

[0001] This utility model relates to the field of aluminum profile production technology, and in particular to an extrusion device for aluminum profile production. Background Technology

[0002] In the production and manufacturing of aluminum profiles, extrusion molding is one of the core processes that determines product quality and specifications. This process usually involves first heating the aluminum profile to the plastic deformation temperature range of 400-500℃, and then applying continuous and stable pressure to the high-temperature aluminum profile with the driving force of the extrusion device. This forces the aluminum profile to overcome the frictional resistance of the mold cavity wall and be extruded from the pre-set orifice of the mold in a streamlined state, ultimately forming an aluminum profile that matches the cross-sectional shape and size of the mold cavity.

[0003] In the production of aluminum profiles, the extrusion unit is crucial in the critical processing stage between preheating and subsequent grinding and transmission. It enables efficient pressure forming of high-temperature aluminum profiles, mold cavity adaptation, and synchronous guidance and output of the formed aluminum material. However, existing extrusion units for aluminum profile production suffer from several problems. When the aluminum profile is heated, its surface reacts with oxygen in the air to form a loose, poorly adhered oxide layer. Uneven heating temperatures and incomplete surface cleaning can also cause burrs and oxidation. During extrusion, the oxide layer and burrs easily embed into the aluminum surface or scratch the profile substrate, increasing surface roughness and reducing smoothness. Furthermore, oxide layer debris generated after heating easily falls into moving parts and gaps in the equipment, exacerbating friction and wear between components. This can cause equipment to jam or even malfunction during operation, severely affecting its stability, shortening its lifespan, and increasing daily maintenance and repair costs.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1:

[0031] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an extrusion device for manufacturing aluminum profiles, including a support frame 1, an extrusion component 2 disposed inside the support frame 1, a feeding frame 3 disposed on the side of the support frame 1, a transmission component 4 disposed on one side of the feeding frame 3, a collection groove 5 disposed below the transmission component 4, a grinding component 6 disposed on the side of the collection groove 5, and a collection component 7 disposed on the side of the transmission component 4.

[0032] The support frame 1 is used to support and fix the extruder 2 to ensure the stability of the extruded aluminum profile. The extruder 2 is used to apply pressure to the heated aluminum profile, so that the aluminum profile is extruded from the die 23 to form an aluminum profile with the required cross-sectional shape. The feeding rack 3 is used to smoothly transport the heated aluminum profile to be extruded to the extrusion area of ​​the extruder 2. The transfer component 4 is used to transfer the heated aluminum profile to the feeding rack 3. The collection tank 5 is used to collect the oxide scale debris that falls off during the grinding process to prevent the debris from scattering and polluting the equipment and the environment. The grinding component 6 is used to grind and clean the oxide scale, burrs and impurities on the surface of the aluminum profile during the transfer process of the transfer component 4 to improve the surface quality of the aluminum profile. The collection component 7 is used to collect and store the oxide scale, burrs and impurities that fall off in the collection tank 5.

[0033] Specifically, the extrusion component 2 includes a cylinder 21 fixedly connected to the inner wall of the support frame 1, an extrusion rod 22 is provided on the inner wall of the support frame 1, and a mold 23 is fixedly connected to the side of the support frame 1.

[0034] The cylinder 21 is used to drive the extrusion rod 22 to move via the slide plate. The extrusion rod 22 is used to push the heated aluminum ingot toward the mold 23 and apply extrusion pressure under the drive of the cylinder 21 and the slide plate. The mold 23 is used to extrude the aluminum profile from its cavity under the pushing force of the extrusion rod 22, thereby forming an aluminum profile with the required cross-sectional shape.

[0035] It should be noted that cylinder 21 is used in conjunction with an air compressor, an air tank, a filter pressure reducing valve, a directional control valve, and a flow control valve. During operation, the air compressor compresses ambient air to a set pressure and stores it in the air tank. The filter pressure reducing valve further purifies the air and stabilizes the pressure before delivering it to the control valve via an air pipe. The directional control valve switches the airflow channel according to an electrical signal, determining the extension and retraction direction of cylinder 21. The flow control valve adjusts the airflow speed, controlling the movement speed of cylinder 21. Compressed air enters either the rod chamber or the rodless chamber of cylinder 21, pushing the piston to move. The piston then drives the piston rod to output linear reciprocating motion.

[0036] Specifically, the transmission component 4 includes a fixed frame 41 disposed on one side of the support frame 1, a rotating roller 42 rotatably connected to the top of the fixed frame 41, and a pulley fixedly connected to one end of the rotating roller 42; the transmission component 4 also includes rollers 43 disposed on the top of the fixed frame 41, and the number of rollers 43 is four; the transmission component 4 also includes a first motor 44 disposed at the bottom of the fixed frame 41, and a pulley fixedly connected to the output end of the first motor 44, and the same first belt 45 is sleeved on the surfaces of the two pulleys at one end of the rotating roller 42 and the output end of the first motor 44.

[0037] The fixed frame 41 is used to support the conveying component 4, the grinding component 6 and the collecting component 7 to ensure the stability of the conveying process. The rotating roller 42 is used to convey the extruded aluminum profile and move it to the feeding rack 3. The roller 43, in conjunction with the rotating roller 42, can move the aluminum profile towards the feeding rack 3 while rotating. The first motor 44 is used to provide the rotation power. Through the pulley at the output end and the first belt 45, it drives the rotating roller 42 to rotate and moves the aluminum profile towards the feeding rack 3. The first belt 45 is used to transmit the power of the first motor 44 so that the rotating roller 42 can rotate continuously.

[0038] Example 2:

[0039] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the grinding component 6 includes a positioning frame 61 fixedly connected to the top of the fixing frame 41, with a connecting rod 62 rotatably connected to one end of the positioning frame 61, and a pulley fixedly connected to the surface of the connecting rod 62; the grinding component 6 also includes three grinding rollers 63 fixedly connected to the surface of the connecting rod 62, the surface material of the grinding rollers 63 being cubic boron nitride; the grinding component 6 also includes a second motor 64 fixedly installed on the top of the fixing frame 41, with a pulley fixedly connected to the output end of the second motor 64; the grinding component 6 also includes a second belt 65, which is sleeved on the pulley on the surface of the connecting rod 62 and the pulley at the output end of the second motor 64; the grinding component 6 also includes three guide plates 66 fixedly connected to the top of the fixing frame 41, with the three guide plates 66 respectively positioned below the three grinding rollers 63.

[0041] The positioning frame 61 supports the connecting rod 62, which in turn supports the grinding roller 63 and drives it to rotate. The grinding roller 63 is used to grind and clean the oxide scale and burrs on the surface of the aluminum profile during transmission. The cubic boron nitride material gives it high hardness and wear resistance, improving the grinding effect and service life. The second motor 64 provides grinding power and outputs torque through the output pulley, driving the second belt 65 to rotate. The second belt 65 is used as the pulley between the connecting rod 62 and the second motor 64, transmitting the power of the second motor 64 to drive the connecting rod 62 and the grinding roller 63 to rotate. The guide plate 66 is used to allow impurities generated during the grinding of the aluminum profile to flow into the collection tank 5.

[0042] It should be noted that in order to improve the load-bearing capacity of belt drives, the wrap angle cannot be too small. Generally, the wrap angle α is required to be ≥120°, and in some cases, α is even required to be ≥150°. This is because a larger wrap angle can provide greater friction, thereby improving the stability and efficiency of the transmission. This technique is common knowledge to those in the field and will not be elaborated on here.

[0043] Example 3:

[0044] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, the collection component 7 includes a collection box 71 slidably connected to the bottom of the fixing frame 41, and a connecting plate 72 rotatably connected to the side of the fixing frame 41; the collection component 7 also includes a fixing block 73 fixedly connected to one end of the connecting plate 72, and a positioning plate 74 fixedly connected to the side of the collection box 71; the surface of the positioning plate 74 is provided with an arc-shaped groove, and the outer side of the fixing block 73 is slidably connected to the inner wall of the arc-shaped groove.

[0046] The collection box 71 is used to store the impurities generated during grinding in the collection tank 5, making it easy to remove and empty. The connecting plate 72 is used to connect the fixing block 73 and adjust its position by rotation to limit the collection box 71 and prevent it from slipping out accidentally. The fixing block 73 cooperates with the arc-shaped groove of the positioning plate 74 to prevent the connecting plate 72 from sliding, so that the connecting plate 72 can continuously and stably limit the collection box 71.

[0047] In use, when the heated aluminum profile is transferred between rollers 43 and rotating rollers 42, the first motor 44 is started. The first motor 44 transmits power through the output pulley and the first belt 45, driving the rotating roller 42 on the top of the fixed frame 41 to rotate. The four rollers 43 work synchronously with the rotating roller 42 to smoothly transfer the aluminum profile to the feeding frame 3. At the same time, the second motor 64 transmits power synchronously through the output pulley and the second belt 65, driving the connecting rod 62 on the positioning frame 61 and the surface grinding roller 63 to rotate. When the aluminum profile enters the grinding frame 4 under the drive of the conveyor 4, the grinding roller 43 rotates. During the grinding process, the aluminum profile can be continuously transported while simultaneously grinding and cleaning its surface oxide scale, burrs, and impurities. The oxide scale debris generated during grinding will fall into the collection groove 5 inside the transmission component 4 under the guidance of the guide plate 66. If the collection box 71 needs to be emptied, the connecting plate 72 is moved to drive the sliding fixing block 73 to slide out of the arc-shaped groove of the positioning plate 74, and the collection box 71 is pulled out to clean the impurities inside. After cleaning, the collection box 71 is pushed into the bottom of the fixing frame 41, and the connecting plate 72 is rotated to fix the collection box 71 so that impurities can be collected later.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
