Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile production technology, specifically referring to an aluminum profile extrusion machine. Background Technology

[0002] An aluminum profile extrusion press is the core equipment for forming aluminum profiles. It applies pressure to heated aluminum billets through an extrusion die, causing the billets to pass through the die cavity and form aluminum profiles with specific cross-sectional shapes. The extrusion die needs to be replaced according to the different cross-sectional specifications of the aluminum profile. Existing equipment usually uses multiple sets of bolts to fix the die to the end of the extrusion cylinder or the die holder. When changing the die, operators need to use special tools such as wrenches and torque wrenches to remove the bolts one by one, resulting in low disassembly and replacement efficiency.

[0003] In addition, after aluminum profiles are extruded from the die, they need to be rapidly cooled by water to ensure the dimensional accuracy and mechanical properties of the profiles. Currently, the mainstream water cooling method involves installing spray pipes above the extrusion end of the extruder, spraying cooling water onto the upper surface of the aluminum profile. However, since the aluminum profiles need to be supported and transported by conveyor rollers after extrusion, these rollers can obstruct the lower surface of the aluminum profile, thus affecting the cooling quality and efficiency. Utility Model Content

[0006] Furthermore, multiple sets of positioning grooves are provided on the extrusion chamber, and the positioning plates correspond one-to-one with the positioning grooves. Multiple sets of fixing components are provided in the fixing cavity, and the fixing plates are connected one-to-one with the fixing components.

[0007] Furthermore, the fixing assembly includes a nut sleeve, a fixing screw, a guide rod, and a drive plate. The nut sleeve is rotatably mounted on the side wall of the fixing cavity.

[0008] Furthermore, the fixing assembly includes two sets of transverse fixing assemblies and two sets of longitudinal fixing assemblies. The fixing cavity is provided with multiple sets of transmission assemblies. The two sets of longitudinal fixing assemblies are respectively connected to one set of transverse fixing assemblies through a set of transmission assemblies, and the other set of transverse fixing assemblies is connected to one set of longitudinal fixing assemblies through a set of transmission assemblies. A set of nut sleeves of the transverse fixing components is connected to the output shaft of the drive motor. A driving bevel gear is fixedly provided on the nut sleeve of the transverse fixing components. The transmission component includes a rotating shaft, a driven bevel gear, and a transmission chain. The rotating shaft is rotatably disposed in a fixed cavity. The driven bevel gear is fixedly disposed on the rotating shaft. The driven bevel gear meshes with the driving bevel gear. Transmission sprockets are fixedly provided on the rotating shaft and the corresponding nut sleeve. The two ends of the transmission chain are sleeved on two corresponding sets of transmission sprockets and mesh with the transmission sprockets.

[0009] Furthermore, a cooling pool is provided outside the extrusion chamber, the cooling pool is filled with coolant, a water pump is provided outside the cooling pool, and a spray head is provided above the cooling pool. The spray head is connected to the conveying roller and the spray head through an upper liquid pipe, and the conveying roller is rotatably connected to the upper liquid pipe.

[0010] Furthermore, the cooling pool is equipped with a partition, a liquid collection chamber is provided above the partition, and a cooling chamber is provided below the partition. The conveying roller is rotatably disposed in the liquid collection chamber. A refrigeration circulation pump is provided outside the cooling pool. The inlet end of the refrigeration circulation pump is connected to the liquid collection chamber through a pipe, and the outlet end is connected to the cooling chamber through a pipe. The water pump is connected to the cooling chamber through a pipe. The conveying roller is connected to the liquid collection chamber through an outlet pipe, and the conveying roller and the outlet pipe are rotatably connected.

[0011] Furthermore, multiple sets of conveying rollers are rotatably arranged on the cooling pool.

The mold is installed and fixed. When changing the mold, there is no need to use special tools such as wrenches and torque wrenches to disassemble and install bolts one by one, which significantly reduces the complexity of mold replacement operation.

[0013] 2. By setting a hollow filler and cooling channel inside the conveying roller, the coolant circulates in the cooling channel. While the conveying roller supports and conveys the aluminum profile, its side wall can be cooled by the coolant, directly contacting the lower surface of the aluminum profile and carrying away heat. This makes up for the defect of the conveying roller blocking the lower surface and causing a cooling blind zone in the prior art. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0018] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0019] See Figures 1-5 In this embodiment, the present invention provides an aluminum profile extrusion press, including an extrusion chamber 1, a mold 4, a fixing plate 6, a conveying roller 7, and a hollow filler 8. The extrusion chamber 1 is provided with a fixing cavity 2 and a positioning groove 3. The positioning groove 3 is provided through the fixing cavity 2. The mold 4 is provided with a positioning plate 5, which is detachably disposed in the positioning groove 3. The positioning plate 5 is provided with a fixing hole. The fixing plate 6 is configured to slide in the fixing cavity 2 to be inserted into the fixing hole to fix the mold 4. The conveying roller 7 is configured to rotate and is used to convey the extruded aluminum profile. The hollow filler 8 is disposed in the conveying roller 7. A cooling channel 9 is provided between the filler 8 and the side wall of the conveying roller 7. Cooling liquid circulates in the cooling channel 9. The filling 8 can effectively reduce the amount of coolant stored in the conveying roller 7. In addition, the hollow filling 8 reduces the overall weight of the conveying roller 7, thereby reducing the rotational energy consumption of the conveying roller 7.

[0020] Understandably, as is existing technology in this field, the extrusion chamber 1 is equipped with a feeding rack and a hydraulic rod. In practical use, the cut aluminum profile raw material is placed on the feeding rack, and the aluminum profile raw material is pushed into the extrusion chamber 1 by the hydraulic rod for continuous extrusion, thereby extruding the aluminum profile from the die 4 to obtain an aluminum profile that matches the die 4. The extruded aluminum profile is received and conveyed by the conveying roller 7, and the coolant can reduce the surface temperature of the conveying roller 7 to cool the lower surface of the aluminum profile.

[0021] When it is necessary to replace the mold 4 with a different one, simply drive the fixing plate 6 to slide within the fixing cavity 2, so that the fixing plate 6 moves out of the fixing hole of the positioning plate 5 of the mold 4, and the mold 4 can be easily removed. When replacing with a new mold 4, drive the fixing plate 6 to slide within the fixing cavity 2, so that the fixing plate 6 is re-inserted into the fixing hole of the positioning plate 5 of the new mold 4, thus realizing the installation of the new mold 4.

[0022] Specifically, see Figure 2 and Figure 4 In this embodiment, multiple sets of positioning grooves 3 are provided on the extrusion chamber 1, and positioning plates 5 correspond one-to-one with positioning grooves 3. The cooperation of multiple sets of positioning plates 5 and positioning grooves 3 can improve the installation stability of mold 4 on extrusion chamber 1. Multiple sets of fixing components are provided in the fixing cavity 2, and fixing plates 6 are connected one-to-one with fixing components.

[0023] Specifically, see Figure 2 and Figure 3 In this embodiment, the fixing assembly includes a nut sleeve 10, a fixing screw 11, a guide rod 12, and a drive plate 13. The nut sleeve 10 is rotatably mounted on the side wall of the fixing cavity 2. The fixing screw 11 is connected to the nut sleeve 10 by threads. The guide rod 12 is fixedly mounted in the fixing cavity 2. The drive plate 13 is slidably mounted on the guide rod 12 and connected to the fixing screw 11. The fixing plate 6 is mounted on the drive plate 13. A drive motor 14 is provided on the side wall of the extrusion chamber 1. The nut sleeves 10 of one set of fixing assemblies are connected to the output shaft of the drive motor 14. The nut sleeves 10 of two adjacent sets of fixing assemblies are connected. When the nut sleeve 10 rotates, the drive plate 13 is driven to slide along the guide rod 12 through the fixing screw 11. The drive plate 13 drives the fixing plate 6 on it to move. Multiple sets of fixing assemblies drive the fixing plate 6 connected to them to be embedded into the fixing hole of their corresponding positioning plate 5, so that the mold 4 is stably installed on the extrusion chamber 1.

[0024] See Figure 2 and Figure 3In one specific embodiment, the fixing assembly includes two sets of transverse fixing assemblies 15 and two sets of longitudinal fixing assemblies 16. Multiple sets of transmission assemblies 17 are provided in the fixing cavity 2. The two sets of longitudinal fixing assemblies 16 are respectively connected to one set of transverse fixing assemblies 15 through a set of transmission assemblies 17, and the other set of transverse fixing assemblies 15 is connected to one set of longitudinal fixing assemblies 16 through a set of transmission assemblies 17. The nut sleeve 10 of one set of transverse fixing assemblies 15 is connected to the output shaft of the drive motor 14. A driving bevel gear 18 is fixedly provided on the nut sleeve 10 of the transverse fixing assembly 15. The transmission assembly 17 includes a rotating shaft 19, a driven bevel gear 20, and a transmission chain 21. The rotating shaft 19 is rotatably disposed in the fixing cavity 2. The driven bevel gear 20 is fixedly disposed on the rotating shaft 19 and meshes with the driving bevel gear 18. Transmission sprockets are correspondingly fixedly disposed on the rotating shaft 19 and the corresponding nut sleeve 10. The two ends of the transmission chain 21 are sleeved on the corresponding two sets of transmission sprockets and mesh with the transmission sprockets.

[0025] In practical use, taking the connection method shown in the attached diagram as an example, the nut cylinder 10 of a set of transverse fixing components 15 connected to the drive motor 14 rotates, and the nut cylinder 10 drives the active bevel gear 18 on it to rotate. Through the meshing of the active bevel gear 18 and the driven bevel gear 20, the shaft 19 of the transmission component 17 connected to it rotates. And through the transmission of the transmission sprocket and the transmission chain 21, the nut cylinder 10 of the longitudinal fixing component 16 can be driven to rotate. The nut cylinder 10 of a set of longitudinal fixing components 16 drives the nut cylinder 10 of another set of transverse fixing components 15 to rotate through another set of connected chains, thereby realizing the rotation drive of the four sets of fixing component nut cylinders 10 to drive and adjust the position of the fixing plate 6.

[0026] Specifically, see Figure 1 , Figure 5 and Figure 6 In this embodiment, a cooling pool 22 is provided outside the extrusion chamber 1. The cooling pool 22 is filled with coolant. A water pump 23 is provided outside the cooling pool 22. A spray head 24 is provided above the cooling pool 22. The spray head 24 is connected to the conveying roller 7 and the spray head 24 through the liquid inlet pipe 25. The conveying roller 7 is rotatably connected to the liquid inlet pipe 25.

[0027] In practical use, the coolant in the cooling pool 22 is drawn out by the water pump 23 and transported to the conveying roller 7 and the spray head 24 through the liquid inlet pipe 25. The spray head 24 sprays the coolant onto the aluminum profile on the conveying roller 7, and at the same time, the coolant in the conveying roller 7 cools the lower part of the aluminum profile. The combination of the two improves the cooling efficiency of the aluminum profile.

[0028] Specifically, see Figure 1 and Figure 5In this embodiment, a partition 26 is provided inside the cooling pool 22, a liquid collection chamber 27 is provided above the partition 26, and a cooling chamber 28 is provided below the partition 26. The conveying roller 7 is rotatably disposed in the liquid collection chamber 27. A refrigeration circulation pump 29 is provided outside the cooling pool 22. The inlet end of the refrigeration circulation pump 29 is connected to the liquid collection chamber 27 through a pipe, and the outlet end is connected to the cooling chamber 28 through a pipe. The refrigeration circulation pump 29 circulates and cools the refrigerant. The water pump 23 is connected to the cooling chamber 28 through a pipe. The conveying roller 7 is connected to the liquid collection chamber 27 through the liquid outlet pipe 34, and the conveying roller 7 and the liquid outlet pipe 34 are rotatably connected.

[0029] In practical use, the coolant sprayed by the spray head 24 and the coolant discharged from the conveyor roller 7 are both collected in the collection chamber 27. After being cooled by the refrigeration circulation pump 29, it is reintroduced into the cooling chamber 28 and then pumped out by the water pump 23 for recycling.

[0030] Specifically, see Figure 5 and Figure 7 In this embodiment, multiple sets of conveying rollers 7 are rotatably arranged on the cooling pool 22. The conveying rollers 7 are equipped with drive sprockets, and drive chains 30 are meshed on the sprockets of two adjacent sets of conveying rollers 7. The drive chains 30 realize the transmission drive between multiple sets of conveying rollers 7. A rotating motor 31 is fixed on the outer wall of the cooling pool 22. A drive gear 32 is provided on the output shaft of the rotating motor 31. A driven gear 33 is provided on one set of conveying rollers 7. The drive gear 32 and the driven gear 33 mesh.

[0031] In practical use, the rotating motor 31 drives the drive gear 32 to rotate, and the drive gear 32 drives the driven gear 33 to rotate, thereby driving a set of conveying rollers 7 to rotate. Through the meshing of the drive chain 30 and the drive sprocket, multiple sets of conveying rollers 7 are driven to rotate synchronously to convey aluminum profiles.
