[0028] Example 1

[0029] See also Figure 1-Figure 6As shown, the purpose of this embodiment is to provide an extruder for an aluminum alloy guide rail, including a base 4, which provides a stable support for the extruder, ensuring the stability and safety of the machine during operation. The design of the base 4 helps to reduce vibration and protect the machine from interference from uneven ground or other external factors, thereby improving the working efficiency of the extruder and the accuracy of the extruded guide rail. An extrusion head 3 is arranged above the base 4, and the extrusion head 3 is responsible for extruding the molten aluminum alloy into a guide rail through a specific mold. Its precise temperature control and pressure regulation capabilities ensure the uniformity and strength of the guide rail. Two cooling devices 1 are arranged on one side of the extrusion head 3 to extrude the guide rail. The two cooling devices 1 quickly cool the newly extruded guide rail to reduce thermal deformation and increase the hardness of the guide rail. The guide rail passes through the center of the two cooling devices 1. A plurality of water supply pipes 5 are connected between the cooling devices 1. These water supply pipes 5 spray water on the surface of the guide rail from different directions to achieve uniform cooling. The design of the cooling device 1 helps to improve production efficiency, because rapid cooling can reduce the residence time of the guide rail during the cooling process, while ensuring the dimensional stability and surface quality of the guide rail. The plurality of water supply pipes 5 The cooling device 1 is arranged in a circular array around the guide rail, and the cooling device 1 rotates around the guide rail to drive a plurality of water supply pipes 5 to rotate with the guide rail as the axis, so that the cooling water can be sprayed onto the guide rail from different angles. This design helps to achieve a more uniform cooling effect and reduce the deformation of the guide rail caused by local overheating or overcooling. A plurality of sliding devices 2 are arranged on the side away from each other of the two cooling devices 1. The plurality of sliding devices 2 support the guide rail. The sliding devices 2 are extended up and down to adapt to guide rails of different thicknesses to ensure the stability of the guide rail during the cooling process. The extension function of the sliding device 2 helps to make the guide rail The guide rail always keeps sliding on the axis line of several water supply pipes 5, so that several water supply pipes 5 can evenly cool the guide rail, ensuring the dimensional stability and surface quality of the guide rail, and the two cooling devices 1 drive several water supply pipes 5 to move around the guide rail, so that several water supply pipes 5 are close to or away from the guide rail. This coordinated movement design allows the cooling water to always closely follow the cooling needs of the guide rail, and no matter how the length of the guide rail changes, the consistency of the cooling effect can be guaranteed. This design improves cooling efficiency, reduces energy consumption, and helps to improve the overall quality of the guide rail.

[0030] The cooling device 1 includes a first slide 18, the bottom of which slides on the cooling device 1, which allows the device to flexibly adjust its position when the length of the guide rail changes, thereby ensuring the uniformity of the cooling effect. A semicircular slot 181 is provided above the first slide 18, and this design allows the gear plate 15 to be rotatably installed therein, providing a compact and stable structure, which helps to improve the working efficiency and stability of the extruder. A plurality of teeth are provided on the side wall of the gear plate 15, and the rotating shaft of the motor 6 is fixedly connected to the lower gear 7, and the upper gear 8 is meshed with the teeth on the lower gear 7, and the upper gear 8 is meshed with the teeth on the gear plate 15, forming a transmission system for the extruder. This design allows the power to be The gear plate 15 is driven to rotate through the meshing transmission of the gears, thereby realizing precise cooling of the aluminum alloy guide rail. The rotation of the gear plate 15 not only improves the efficiency of the extrusion process, but also helps to maintain the consistency and uniformity of the guide rail. A motor 6 is installed at the bottom of the first slide 18. The motor 6 is fixedly installed below the cooling device 1. The motor 6 drives the gear plate 15 to rotate through the rotating shaft. This direct connection method simplifies the power transmission path, reduces energy loss, and improves the energy efficiency of the extruder. The motor 6 drives the gear plate 15 to rotate through the rotating shaft. This design allows the extruder to adjust the speed as needed to adapt to different cooling requirements, thereby improving the flexibility and adaptability of the cooling process.

[0031] A positioning plate 16 is fixedly installed on one side of the gear plate 15 close to the extruder head 3. A plurality of slots are provided around the guide rail annular array on the side of the positioning plate 16 close to the extruder head 3. This structural design enables the positioning plate 16 to accurately fix the gear plate 15, reducing the cooling degree problem caused by position deviation, which is beneficial to improving the machining accuracy and production efficiency of the guide rail. An inner rotating ring 14 is installed on the center rotation of the gear plate 15. The inner rotating ring 14 rotates freely during the cooling process to reduce friction and wear. A locking rod 17 is hinged on the side wall of the inner rotating ring 14. This structural design enables the inner rotating ring 14 to be locked when necessary to prevent it from rotating unnecessary during the cooling process, thereby ensuring the stability of the cooling process. In order to improve the quality of the guide rail, a torsion spring is provided at the hinge of the locking rod 17 and the inner swivel 14, which pushes the locking rod 17 to squeeze the positioning plate 16, and makes the wedge block provided on the side of the locking rod 17 close to the gear plate 15 be clamped in the groove, thereby fixing the inner swivel 14 on the gear plate 15, so that the inner swivel 14 cannot rotate. This mechanism ensures that the inner swivel 14 is fixed on the gear plate 15 and cannot rotate, thereby ensuring precise control during the cooling process and consistency of the guide rail. Through this locking mechanism, the inner swivel 14 can be prevented from rotating incorrectly, which helps to accurately control the distribution of the coolant, ensure that all parts of the aluminum alloy guide rail are cooled evenly during the cooling process, and reduce deformation of the guide rail caused by uneven cooling.

[0032] A plurality of swinging rods 12 are fixedly arranged in a circular array on one side of the positioning plate 16 away from the gear plate 15, so that the swinging rods 12 can swing in a circular array around the guide rail, which helps to achieve all-round cooling of the guide rail by the water supply pipe 5. A first hinge rod 121 is rotatably installed on one end of the plurality of swinging rods 12 away from the guide rail. Such a structure allows the swinging rod 12 to rotate at the end away from the guide rail, which increases the flexibility and adaptability of the cooling system, so that the water supply pipe 5 can cool the guide rail more effectively from different angles. An end of the first hinge rod 121 close to the positioning plate 16 passes through the positioning plate 16 and is fixedly installed on the bottom surface of the gear plate 15. The water supply pipe 5 is fixedly installed on one end of the swinging rod 12 away from the first hinge rod 121. A plurality of The nozzle reduces the flow cross-section of the liquid through the nozzle, thereby increasing the pressure of the water flow and speeding up the flow of water, which can make the cooling of the guide rail more efficient. When the gear plate 15 rotates, the swing rod 12 drives the water supply pipe 5 to rotate around the guide rail, so that the water supply pipe 5 rotates through the nozzle to spray water on the surface of the guide rail from different directions. This rotational spraying method helps to improve the cooling uniformity of the guide rail, reduce the deformation of the guide rail caused by uneven cooling, and improve the production efficiency. The swing rod 12 swings around the first hinge rod 121, driving the water supply pipe 5 to move closer to or away from the guide rail, so that the water supply pipe 5 can adjust the distance from the guide rail as needed, optimize the cooling effect, and enable the extruder to effectively cool guide rails of different sizes, thereby improving the applicability and flexibility of the extruder.

[0033] A movable sleeve 13 is provided on the middle sliding sleeve of the swing arm 12, and the movable sleeve 13 slides and squeezes the side wall of the swing arm 12. This structure not only provides flexibility for the swing arm 12 in operation, but also enhances its structural stability through the squeezing effect, ensuring the durability and reliability of the swing arm 12 under frequent operation, while allowing the water supply pipe 5 to dynamically adjust the distance from the guide rail to achieve a more precise and uniform cooling effect. Through the swing of the swing arm 12, the extruder can adapt to guide rails of different shapes and sizes, thereby improving the adaptability and flexibility of the cooling process. The swing arm 12 swings around the first hinged rod 121, thereby driving the water supply pipe 5 close to the guide rail, so that the water supply pipe 5 can optimize the coolant injection according to the specific needs of the guide rail, such as shape, length and cooling requirements, which not only improves the cooling efficiency, but also helps to reduce material waste and improve production efficiency. At the same time, it can also make real-time adjustments based on the cooling feedback of the guide rail, thereby ensuring the quality and performance of the guide rail during the cooling process.

[0034] An outer swivel ring 11 is provided on the side of the movable sleeve 13 away from the gear plate 15. The outer swivel ring 11 is fixedly connected to the inner swivel ring 14 through a plurality of connecting blocks 111, which not only enhances the stability of the extruder structure, but also allows the outer swivel ring 11 to achieve relative movement with the swing rod 12 through the movable sleeve 13 while being fixedly connected, thereby improving the flexibility of the extruder and the ability to adapt to different production needs. The side of the movable sleeve 13 close to the outer swivel ring 11 is hinged to the outer swivel ring 11 through a second hinged rod 131, and the hinge point is set between a plurality of connecting blocks 111. This design allows the outer swivel ring 11 to achieve relative movement with the swing rod 12 through the second hinged rod 131 while being fixedly connected, so that the cooling system of the extruder can dynamically adjust the position of the water supply pipe 5 to adapt to different production needs. The shape and size of the guide rail improves the adaptability and flexibility of the cooling process. The rotation of the inner swivel 14 drives the outer swivel 11 to rotate. The rotation of the outer swivel 11 causes several movable sleeves 13 to swing, so that the movable sleeve 13 squeezes the swing rod 12, and the swing rod 12 swings around the first hinge rod 121, thereby driving several water supply pipes 5 to approach the guide rail, realizing the precise injection of coolant. The wedge block on the locking rod 17 is clamped in the groove of the gear plate 15, so that the inner swivel 14 can no longer rotate, thereby making the distance between the several water supply pipes 5 and the guide rail relatively fixed. This locking mechanism ensures the accuracy and consistency of coolant injection, avoids the displacement of the cooling device 1 due to equipment vibration or accidental impact, thereby ensuring the consistency and reliability of the cooling effect, and improving the quality and performance of the guide rail.

[0035] The sliding device 2 includes a second slide seat 21 slidably arranged on the base 4 to adapt to aluminum alloy guide rails of different lengths and shapes to ensure the adaptability of the extruder and the continuity of the extrusion process. The upper side of the second slide seat 21 is set as a notch, and the side walls on both sides of the notch are provided with slide grooves. A roller core 24 is arranged in the notch, and a sleeve roller 23 is slidably sleeved on the outside of the roller core 24. The guide rail rolls on a plurality of sleeve rollers 23, so that the aluminum alloy guide rail moves and cools smoothly after extrusion, reducing the friction and heat generated by direct contact with the extruder and protecting the guide rail surface from damage. The use of the sleeve roller 23 improves the transmission efficiency of the guide rail, reduces energy consumption, and ensures the uniformity and consistency of the guide rail during the cooling process.

[0036] Both ends of the roller core 24 are clamped in the slide groove and slide up and down, so that the roller core 24 can adjust its position as needed to adapt to guide rails of different sizes, ensuring stable support and precise positioning of the guide rails. Through the guidance of the slide groove, the movement of the roller core 24 is smoother and more controllable, which helps to improve the operating efficiency of the extruder and the processing accuracy of the guide rail. A screw 22 is provided at the upper end of the slide groove. The bottom of the screw 22 passes through the top of the slot side wall and is rotatably connected to the end of the roller core 24. By rotating the screw 22, the sleeve roller 23 can be driven to slide up and down, thereby dynamically supporting the guide rail. This design allows the guide rail to be height-adjusted according to actual needs during the cooling process, ensuring that the guide rail is always located on the axis of several water supply pipes 5, which helps to achieve uniform cooling.

[0037] The two lower gears 7 are coaxially connected by a connecting rod 9, and the shaft of the motor 6 drives the two lower gears 7 to rotate synchronously. The synchronously rotating lower gears 7 can ensure the uniform distribution of force and the stability of the extruder during the cooling process, which is crucial to improving the cooling efficiency and the quality of the guide rail. At the same time, the synchronous rotation also reduces the mechanical wear and energy consumption caused by the mismatch of gear speeds, thereby improving the operating efficiency and life of the extruder. The two lower gears 7 drive the two gear plates 15 to rotate synchronously, and then drive several movable sleeves 13 to swing around the guide rail synchronously, so that the two ends of several water supply pipes 5 are synchronously close to the guide rail. This synchronous approach ensures that the coolant can be evenly sprayed onto the surface of the guide rail, thereby improving the cooling efficiency and the cooling quality of the guide rail. The synchronous approach also helps to reduce uneven cooling caused by inaccurate position of the water supply pipe 5, thereby avoiding deformation or cracking of the guide rail due to temperature differences, and ensuring the dimensional stability and mechanical properties of the guide rail.

[0038] When this embodiment is used, the extrusion head 3 is installed on the base 4, and the molten aluminum alloy is extruded into a guide rail. The formed guide rail slides on a plurality of sleeve rollers 23, and preliminary natural heat dissipation is performed in this process. At the same time, friction is reduced and the surface of the guide rail is protected. With the further extrusion of the extrusion head 3, this part of the guide rail enters between a plurality of water supply pipes 5, and the motor 6 drives the lower gear 7 to rotate synchronously through the rotating shaft. The connecting rod 9 transmits power to another lower gear 7 to ensure that the two gear plates 15 rotate synchronously, thereby driving a plurality of water supply pipes 5 to evenly spray coolant around the guide rail, ensuring that each part of the aluminum alloy guide rail is evenly cooled during the cooling process, and reducing the deformation of the guide rail caused by uneven cooling; the inner swivel 14 is connected to the guide rail by a torsion spring and a locking rod The wedge block on 17 is fixedly connected to the gear plate 15 to ensure that the inner swivel 14 cannot rotate during cooling, thereby fixing the distance between the water supply pipe 5 and the guide rail to ensure uniform cooling; by turning the screw 22, the sleeve roller 23 can be driven to slide up and down, thereby dynamically supporting the guide rail and adjusting the distance between several water supply pipes 5 and the guide rail at the same time, so that the guide rail can be height-adjusted according to actual needs during the cooling process, ensuring that the guide rail is always located on the axis line of several water supply pipes 5, which helps to achieve uniform cooling, and flexibly adjusts the distance between several water supply pipes 5 and the guide rail according to guide rails of different sizes. After extrusion and cooling, the aluminum alloy guide rail is rolled and transmitted by several sleeve rollers 23 away from the extrusion head 3, and output as a finished product.
