Description

Technical Field

[0001] This application relates to the field of aluminum alloy profile processing, and in particular to a high-efficiency flow guiding device for hot extrusion of aluminum alloy profiles. Background Technology

[0002] Aluminum alloy profile processing is the process of using aluminum alloy as raw material and processing aluminum alloy ingots or bars into metal materials with specific cross-sectional shapes through processes such as extrusion, cutting, and surface treatment. Hot extrusion of aluminum alloy profiles is a process in which aluminum alloy billets are heated to above the recrystallization temperature and pressure is applied through a die to plastically deform them into profiles with specific cross-sectional shapes. In conventional hot extrusion of aluminum alloy profiles, the heated material is fed into the connecting pipe from one end. A fixing seat is installed on the inner wall of the connecting pipe, and a flow guide die is clamped into the inner wall of the fixing seat. After the material is shaped by the flow guide die, it is extruded from the other end of the flow guide die and cooled and shaped, thus completing the processing of aluminum alloy.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional flow guiding molds are often installed by directly fixing them inside the connecting pipe. When extruding different types of aluminum alloy parts, different flow guiding molds need to be replaced, which makes the installation and disassembly of the flow guiding molds inconvenient and affects the ease of use of the flow guiding molds.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the inconvenience of installing and disassembling conventional flow guiding dies, this application provides a high-efficiency flow guiding device for hot extrusion of aluminum alloy profiles.

[0006] The high-efficiency flow guiding device for hot extrusion of aluminum alloy profiles provided in this application adopts the following technical solution: A high-efficiency flow guiding device for hot extrusion of aluminum alloy profiles includes a connecting pipe and a connecting block. A fixing seat is fixedly installed on the inner wall of the connecting pipe, and a flow guiding mold is snapped into the inner wall of the fixing seat. Two fixing clamps are rotatably connected to the inner wall of the connecting block. Two slots adapted to the fixing clamps are opened on the inner wall of the connecting pipe. The two slots are symmetrically distributed about the connecting block as an axis. The bottom end of the connecting block is snapped into the top of the flow guiding mold, and the surface of the connecting block is slidably connected to the inner wall of the connecting pipe. The inner wall of the slot is snapped into one end of the fixing clamp.

[0007] Preferably, a return spring is engaged between the two fixing clips, and the inner wall of the return spring is fixedly installed with the inner wall of the connecting frame.

[0008] Preferably, a limiting frame is slidably installed on the top of the connecting block, the inner wall of the limiting frame is engaged with the inner walls of the two fixing clamps, and the surface dimensions of the limiting frame are adapted to the dimensions of the gap between the two fixing clamps.

[0009] Preferably, one end of the limiting frame is fixedly connected to a locking block, the surface of the locking block engaging with the surface of the connecting block, and the end of the limiting frame away from the locking block is engaged with two fixing bolts, the surfaces of the fixing bolts being threaded onto the inner wall of the connecting block.

[0010] Preferably, two auxiliary rings are fixedly connected to the surface of the connecting block. The auxiliary rings are rubber rings, and the surfaces of the auxiliary rings are movably installed with the inner wall of the connecting pipe. The dimensions of the auxiliary ring surfaces are interference-fitted with the dimensions of the inner wall of the connecting pipe.

[0011] Preferably, a shielding block is fixedly connected to the bottom end of the connecting block. The shielding block is a perfluoroether rubber block, and the size and specifications of the bottom end of the shielding block are compatible with the size and specifications of the bottom end of the connecting block.

[0012] Preferably, the inner wall of the shielding block is provided with a groove, and a slider is slidably installed on the inner wall of the groove. The bottom end of the slider is fixedly connected to the top of the flow guiding mold, and the size of the slider surface is adapted to the size of the inner wall of the groove.

[0013] In summary, this application includes the following beneficial technical effects: By installing the connecting block on top of the flow guide mold, two fixing clips are rotatably connected to the inner wall of the connecting block. The surface of the fixing clips engages with the groove on the inner wall of the connecting pipe, allowing the connecting block to be disassembled by separating the fixing clips from the groove. This makes it more convenient to replace the flow guide mold at the bottom of the connecting block. A return spring is installed between the two fixing clips to keep the fixing clips engaged with the groove. A limit frame is slidably installed on the top of the connecting block, and the inner wall of the limit frame is connected to the two fixing clips to fix them, effectively improving the stability of the fixing clips after installation. A locking block is fixedly installed at the bottom of the limit frame, and two fixing bolts are engaged with the inner wall of the limit frame to fix the limit frame to the top of the connecting block. Compared with the existing technology, this significantly improves the convenience of processing different types of aluminum alloy profiles. Two rubber auxiliary rings can be installed on the surface of the connecting block to shield the connecting pipe from the connecting block. A perfluoroether rubber shielding block is installed at the bottom of the connecting block to shield the high temperature inside the connecting pipe and prevent damage to the auxiliary rings. A groove is provided at the bottom of the shielding block, and a slider is slidably connected to the inner wall of the groove. This allows the flow guide mold to be disassembled by separating the slider from the groove, making it easy to replace different models of flow guide molds. This effectively improves the performance of the device. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0017] This application discloses a high-efficiency flow guiding device for hot extrusion of aluminum alloy profiles, referring to... Figure 1 - Figure 2 The system includes a connecting pipe 1. During hot melt extrusion, the heated material is fed into the connecting pipe 1 from one end. A fixing seat 2 is installed on the inner wall of the connecting pipe 1. A flow guide mold 3 is clamped to the inner wall of the fixing seat 2. After the material is shaped by the flow guide mold 3, it is extruded from the other end of the flow guide mold 3 and cooled and shaped, thus completing the processing of aluminum alloy. A connecting block 4 is installed on the top of the flow guide mold 3. Two fixing clips 5 are rotatably connected to the inner wall of the connecting block 4. The surface of the fixing clips 5 is clamped to the groove 6 on the inner wall of the connecting pipe 1. By clamping the fixing clips 5 and the groove 6, the flow guide mold 3 at the bottom of the connecting block 4 is fixed in the connecting pipe 1. The connecting block 4 can be disassembled by separating the fixing clips 5 from the groove 6, which makes it more convenient to replace the flow guide mold 3 at the bottom of the connecting block 4.

[0018] Reference Figure 2A return spring 7 is installed between the two fixing clips 5. The inner wall of the return spring 7 is fixedly connected to the inner wall of the connecting block 4. The return spring 7 pushes one end of the two fixing clips 5, thereby keeping the fixing clips 5 locked in the slot 6, thus improving the installation effect of the connecting block 4. A limit frame 8 is slidably installed on the top of the connecting block 4. The inner wall of the limit frame 8 is connected to the two fixing clips 5. The limit frame 8 fixes the two fixing clips 5, thereby preventing the fixing clips 5 from loosening and effectively improving the stability of the fixing clips 5 after installation. A locking block 9 is fixedly installed at the bottom of the limit frame 8. The surface of the locking block 9 is locked in contact with the surface of the connecting block 4. Two fixing bolts 10 are locked in contact with the inner wall of the limit frame 8. The surface of the fixing bolts 10 is connected to the internal thread of the connecting block 4. The limit frame 8 is fixed to the top of the connecting block 4 by means of the fixing bolts 10 and the locking block 9. The limit frame 8 can be disassembled after the fixing bolts 10 are removed.

[0019] Reference Figure 2 - Figure 4 Two rubber auxiliary rings 11 are installed on the surface of the connecting block 4. The auxiliary rings 11 shield the connecting pipe 1 and the connecting block 4 to prevent material leakage from the connecting pipe 1. A shielding block 12 made of perfluoroether rubber is installed at the bottom of the connecting block 4. The shielding block 12 shields the high temperature inside the connecting pipe 1 to prevent the auxiliary rings 11 from being damaged by the high temperature. It also works with the auxiliary rings 11 to improve the sealing performance of the connecting block 4. A groove 13 is opened at the bottom of the shielding block 12. A slider 14 is slidably connected to the inner wall of the groove 13. The bottom end of the slider 14 is fixedly connected to the top of the flow guide mold 3. The connecting block 4 and the flow guide mold 3 are connected by the slider 14 and the groove 13. The flow guide mold 3 can be disassembled by separating the slider 14 from the groove 13, so as to facilitate the replacement of different models of flow guide mold 3.

[0020] The implementation principle of the high-efficiency flow guiding device for hot extrusion of aluminum alloy profiles in this application embodiment is as follows: A connecting block 4 is installed on top of the flow guiding mold 3. Two fixing clips 5 are rotatably connected to the inner wall of the connecting block 4. The surface of the fixing clips 5 engages with the groove 6 on the inner wall of the connecting pipe 1, thereby fixing the flow guiding mold 3 at the bottom of the connecting block 4 inside the connecting pipe 1. Separating the fixing clips 5 from the groove 6 allows for disassembly of the connecting block 4, making replacement of the flow guiding mold 3 at the bottom of the connecting block 4 more convenient. A return spring 7 is installed between the two fixing clips 5, and the inner wall of the return spring 7 is fixedly connected to the inner wall of the connecting block 4, allowing the return spring 7 to push one end of the two fixing clips 5 from... The fixing clip 5 is kept engaged with the slot 6, thereby improving the installation effect of the connecting block 4. The top of the connecting block 4 is slidably mounted with a limiting frame 8. The inner wall of the limiting frame 8 is connected to the two fixing clips 5, so as to fix the two fixing clips 5 with the limiting frame 8, thereby preventing the fixing clips 5 from loosening and effectively improving the stability of the fixing clips 5 after installation. The bottom end of the limiting frame 8 is fixedly mounted with a locking block 9. The surface of the locking block 9 is engaged with the surface of the connecting block 4. The inner wall of the limiting frame 8 is engaged with two fixing bolts 10. The surface of the fixing bolts 10 is connected to the internal thread of the connecting block 4, so as to fix the limiting frame 8 to the top of the connecting block 4 with the fixing bolts 10 and the locking block 9. The limiting frame 8 can be disassembled after the fixing bolts 10 are removed.

[0021] Two rubber auxiliary rings 11 can also be installed on the surface of the connecting block 4 to shield the connecting pipe 1 and the connecting block 4, preventing material leakage from the connecting pipe 1. A shielding block 12 made of perfluoroether rubber is installed at the bottom of the connecting block 4 to shield the high temperature inside the connecting pipe 1, preventing damage to the auxiliary rings 11 caused by the high temperature. The auxiliary rings 11 also improve the sealing performance of the connecting block 4. A groove 13 is provided at the bottom of the shielding block 12. A slider 14 is slidably connected to the inner wall of the groove 13. The bottom of the slider 14 is fixedly connected to the top of the flow guide mold 3, so that the connecting block 4 and the flow guide mold 3 can be connected by the slider 14 and the groove 13. The flow guide mold 3 can be disassembled by separating the slider 14 from the groove 13, so as to facilitate the replacement of different models of flow guide mold 3.
