Description

Technical Field

[0001] This invention belongs to the field of aluminum alloy profile processing technology, and more specifically, it is a production process for isothermal extrusion square tube aluminum alloy profiles. Background Technology

[0002] This production process is a method of extruding round aluminum alloy profiles into square aluminum alloy profiles through isothermal extrusion. Isothermal extrusion is a special metal processing technology. Its key is that the temperature of the metal in the deformation zone near the die hole can be kept constant or basically constant throughout the entire processing. This can ensure the deformation resistance and flow uniformity of the metal, thereby keeping the die surface pressure constant or basically constant.

[0003] Patent document CN104959395B discloses an isothermal extrusion processing method for square aluminum alloy profiles, comprising: selecting extrusion equipment and calculating the dimensions of the extrusion billet according to the specifications of the square aluminum alloy profile to be processed; determining the heating temperature of the extrusion billet, the temperature of the extrusion die, the temperature of the extrusion pad, and the temperature of the extrusion cylinder based on extrusion production experience and data of the square aluminum alloy profile to be processed; setting a segmented speed-changing model of the extrusion bar in the control system of the extrusion equipment, dividing the total extrusion stroke of 150mm into 5 segments, and controlling the extrusion speed separately. This ensures that the exit temperature of the square aluminum alloy profile is maintained within a certain range, thereby ensuring the uniformity of the microstructure and properties of the profile along the extrusion direction and improving the stability of the profile's hardness, strength, and plasticity.

[0004] Traditional processes have certain shortcomings in processing square aluminum alloy profiles, such as the specifications of square aluminum alloy profiles... Figure 9 As shown, various specifications exist, and the above-mentioned process cannot be arbitrarily adjusted according to the structural characteristics of square aluminum alloy profiles, resulting in the ability to process only one type of square aluminum alloy profile, leading to a single function. Secondly, although the adjustable mold structure can meet the processing operations of different types of square aluminum alloy profiles, the stability of the adjustable mold structure is poor during the extrusion and shaping operation, making the square aluminum alloy profiles prone to deformation during the shaping process, thus reducing the processing effect of the square aluminum alloy profiles. At the same time, the traditional process cannot flexibly apply to aluminum alloy profile raw materials of different lengths, increasing the difficulty of loading and unloading operations and reducing its work efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a production process for isothermal extrusion of square aluminum alloy profiles, which can solve existing problems.

[0006] The problem solved by this invention is:

[0007] 1. Specifications of square aluminum alloy profiles as follows: Figure 9As shown, there are multiple specifications, and the above process cannot be arbitrarily adjusted according to the structural characteristics of the square tube aluminum alloy profile, which means that it can only process one type of square tube aluminum alloy profile, resulting in a single function.

[0008] 2. Secondly, the adjustable mold structure can meet the processing operations of different types of square aluminum alloy profiles. However, the stability of the adjustable mold structure is poor during the extrusion and shaping operation, which makes the square aluminum alloy profiles prone to deformation during the shaping process, thus reducing the processing effect of the square aluminum alloy profiles.

[0009] 3. At the same time, traditional processes cannot flexibly adapt to aluminum alloy profiles of different lengths, which increases the difficulty of loading and unloading operations and reduces work efficiency.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0011] A production process for isothermal extrusion of square aluminum alloy profiles includes the following steps:

[0012] Step 1: Place the round aluminum alloy profile in the feeding box of the processing equipment. Adjust the conveying position of the round aluminum alloy profile by using the guide wheels of the feeding box and several sets of limit blocks to transfer the round aluminum alloy profile onto the conveying wheel.

[0013] Step 2: The round aluminum alloy profile is transported into the heating furnace by the conveyor rollers, and the round aluminum alloy profile is heated by the heating furnace.

[0014] Step 3: The heated circular aluminum alloy profile is conveyed to the extrusion die by the feeding roller. The limiting side plate and the limiting bottom plate are moved by the adjusting seat. The angle of the limiting side plate and the limiting bottom plate is adjusted. The extrusion plate is driven to move down by the hydraulic push rod. The circular aluminum alloy profile is isothermally extruded between the extrusion plate, the limiting bottom plate and the two sets of limiting side plates to make it into a square tube aluminum alloy profile.

[0015] Step four: Use the pusher in conjunction with the lifting push plate to move the square aluminum alloy profile, and use the conveying roller to remove the square aluminum alloy profile from the extrusion die.

[0016] As a further technical solution of the present invention, when the limiting side plate and the limiting bottom plate are used, the limiting side plate and the limiting bottom plate are fixed by the docking block, and the lower and upper insert rods of the docking block are respectively connected to the slots of the limiting side plate and the limiting bottom plate. When performing the extrusion operation of A-type square tube aluminum alloy profile, the two sets of limiting side plates and the limiting bottom plate are kept in a vertical state.

[0017] As a further technical solution of the present invention, when the limiting side plate and the limiting bottom plate are in use, the motor is started to drive the lead screw to rotate under the pressing state of the extrusion plate. The lead screw drives the threaded sliding sleeve to move, and the lifting sleeve of the threaded sliding sleeve drives the limiting bottom plate to move. Thus, the limiting bottom plate drives the two sets of limiting side plates, so that the two sets of limiting side plates are in an inclined state, and the shaping operation of the C-shaped square tube aluminum alloy profile is completed.

[0018] As a further technical solution of the present invention, when the limiting side plate and the limiting bottom plate are in use, the docking angle between the two sets of limiting side plates and the limiting bottom plate is adjusted by the docking block, so that the two sets of limiting side plates are symmetrically inclined at the upper end of the limiting bottom plate. In this state, the extrusion plate is used to extrude the circular aluminum alloy profile to complete the shaping operation of the B-type square tube aluminum alloy profile.

[0019] As a further technical solution of the present invention, when the adjusting seat is used, the lifting sleeve adjusts its height according to the position of the limiting base plate. When the extrusion plate performs the pressing operation, the four vertical push rods move upward, so that the vertical push rods support and fix the lower part of the limiting base plate.

[0020] As a further technical solution of the present invention, when the extrusion plate is used, the transverse push rod is activated, which drives the side top plate to move horizontally, so that the side top plate is pressed against one side of the limiting side plate, and the two sets of limiting side plates are assisted in supporting the extrusion plate when it is pressed down.

[0021] As a further technical solution of the present invention, when the limit block is in use, the motor and screw drive the threaded sleeve, so that the threaded sleeve drives the moving frame to move horizontally, and the moving frame simultaneously drives the three sets of limit blocks to move.

[0022] As a further technical solution of the present invention, when the limit block is used, the three sets of limit blocks are slidably adjusted according to the length of the circular aluminum alloy profile by using the sliding groove on the upper part of the moving frame, thereby adjusting the position of the guide wheels on the three sets of limit blocks.

[0023] As a further technical solution of the present invention, when the pusher is in use, the drive motor drives the gear, and the toothed structure on the surface of the lifting push plate drives the lifting push plate to move up and down, thereby adjusting the position of the lifting push plate.

[0024] As a further technical solution of the present invention, when the pusher is in use, the pusher is driven by the movable casters, so that the pusher moves on the surface of the pressing base. The lifting push plate pushes one end of the square tube aluminum alloy profile, so that the other end of the square tube aluminum alloy profile extends out from the pressing base, and the material conveying wheel moves the square tube aluminum alloy profile out.

[0025] The processing equipment includes a fixed base, with a limit block, a heating furnace and an extrusion die arranged sequentially on the upper end of the fixed base. A feeding wheel is movably installed in the middle of the upper end of the fixed base, and an inclined feeding box is fixedly installed on the outer side of the fixed base. The extrusion die includes a pressing base and a fixed frame. The pressing base is located at the lower end of the fixed frame, and an extrusion plate is movably installed on the inner side of the fixed frame.

[0026] The extrusion plate and the fixed frame are driven by a hydraulic push rod. Two sets of limiting side plates are movably installed inside the pressing base through a rotating shaft. The two sets of limiting side plates are symmetrically arranged. A limiting base plate is provided at the lower part of the two sets of limiting side plates. The limiting side plates and the limiting base plate are fixed by a docking block. A transverse push rod is provided on one side of the limiting side plate. An adjusting seat is provided at the lower part of the limiting base plate. A threaded sliding sleeve that cooperates with the limiting base plate is movably installed at the upper end of the adjusting seat.

[0027] The threaded sliding sleeve and the limiting base plate are connected by a lifting sleeve and a rotating shaft. The adjusting seat and the threaded sliding sleeve are driven by a screw and a motor. The four corners of the adjusting seat are provided with vertical push rods for use with the limiting base plate. There are three sets of limiting blocks.

[0028] The bottom of the limiting block is provided with a movable frame, and the limiting block and the movable frame are movably connected through a sliding groove. One end of the limiting block is provided with a guide wheel, and the inner side of the limiting block is provided with a fastening cap. A threaded sleeve is fixedly installed in the middle of the lower end of the movable frame.

[0029] A lower insertion rod and an upper insertion rod are fixedly installed on one side of the docking block. The lower insertion rod is located below the upper insertion rod. The surfaces of both the lower and upper insertion rods are provided with shafts. The side of the limiting base plate is provided with several sets of slots that cooperate with the lower insertion rod.

[0030] The pusher has a movable lifting push plate inside, a drive motor is provided between the pusher and the lifting push plate, the outer surface of the lifting push plate is provided with tooth grooves, and the lower part of the pusher is provided with casters;

[0031] A limiting side plate is movably installed at one end of the transverse push rod. The transverse push rod and the limiting side plate are movably connected through a rotating bracket. The extrusion plate, the two sets of limiting side plates and the limiting bottom plate all have electric heating structures, which allows the aluminum alloy material to be isothermally extruded and shaped.

[0032] The beneficial effects of this invention are:

[0033] 1. By setting up an adjusting seat and a docking block, during the production process of this isothermal extruded square aluminum alloy profile, in conjunction with the use of two sets of limiting side plates and limiting bottom plates, it achieves an adjustable isothermal extrusion shaping structure, which can meet the requirements of... Figure 9The extrusion and shaping of square aluminum alloy profiles of any shape in China expands the applicability of this production process;

[0034] During operation, there are three processing states. In state one, the processing of A-type square aluminum alloy profiles, the limiting side plates and limiting bottom plates are fixed by the docking blocks. The lower and upper insert rods of the docking blocks are used to align with the slots of the limiting side plates and limiting bottom plates, so that the two sets of limiting side plates and limiting bottom plates are kept perpendicular after docking. At this time, the heated round aluminum alloy profile is placed between the two sets of limiting side plates and limiting bottom plates, and the extrusion plate is used to extrude the round aluminum alloy profile from above, completing the shaping operation of the A-type square aluminum alloy profile. State 2: Processing of C-shaped square aluminum alloy profiles. Based on the processing of A-shaped square aluminum alloy profiles, the processing of C-shaped square aluminum alloy profiles is completed by adjusting the angle of the two sets of limiting side plates. During operation, with the extrusion plate under pressure, the motor is started, which drives the lead screw to rotate. The lead screw drives the threaded sliding sleeve to move, and the lifting sleeve of the threaded sliding sleeve drives the limiting base plate to move. This causes the limiting base plate to drive the two sets of limiting side plates, making both sets of limiting side plates tilted, thus completing the shaping operation of the C-shaped square aluminum alloy profile. State 3: Processing of B-type square aluminum alloy profiles. By reinstalling two sets of limiting side plates, during operation, the docking angle between the two sets of limiting side plates and the limiting bottom plate is adjusted using the docking blocks, so that the two sets of limiting side plates are symmetrically tilted at the upper end of the limiting bottom plate. In this state, the extrusion plate is used to extrude the round aluminum alloy profile, so as to complete the shaping operation of the B-type square aluminum alloy profile, thereby completing the isothermal extrusion shaping of various shapes of square aluminum alloy profiles and improving its processing flexibility.

[0035] 2. By setting horizontal push rods and vertical push rods, the use of two sets of limiting side plates and limiting bottom plates can be optimized when this isothermal extrusion square tube aluminum alloy profile is used, thereby improving the stability of its adjustable mold structure, avoiding deformation of the square tube aluminum alloy profile, and improving its shaping effect.

[0036] During operation, when the extrusion plate presses the material, the four vertical push rods move upward, supporting and fixing the lower part of the limiting base plate, thus improving the structural stability of the limiting base plate. Next, the horizontal push rod is activated, driving the side top plate to move horizontally, so that the side top plate rests against one side of the limiting side plate. When the extrusion plate presses down, it assists in supporting the two sets of limiting side plates. At the same time, the side top plate is connected to the horizontal push rod through the rotating bracket, allowing the side top plate to be arbitrarily adjusted according to the angle of the limiting side plate, making it suitable for auxiliary support when shaping square tube aluminum alloy profiles of different specifications, thus completing the reinforcement operation of the two sets of limiting side plates and the limiting base plate.

[0037] 3. By setting up a pusher and a limit block, the loading and unloading structure of the isothermal extruded square aluminum alloy profile is optimized during the production process, so that it can be adjusted arbitrarily according to the length of the aluminum alloy raw material, thereby improving the loading and unloading efficiency.

[0038] During operation, the limit blocks can be adjusted by sliding the three sets of limit blocks according to the length of the round aluminum alloy profile using the sliding groove on the upper part of the moving frame. This adjusts the position of the guide wheels on the three sets of limit blocks. When the round aluminum alloy profile is discharged from the feeding box, the guide wheels of the three sets of limit blocks restrict the movement of the round aluminum alloy profile, ensuring that the round aluminum alloy profile falls precisely above the conveying wheel. When the pusher is in use, the drive motor drives the gears, and the toothed structure on the surface of the lifting push plate moves the lifting push plate up and down. The position of the lifting push plate is adjusted, and the pusher is driven by the casters, allowing it to move on the surface of the pressing base. The lifting push plate pushes one end of the square aluminum alloy profile, causing the other end of the square aluminum alloy profile to extend from the pressing base, and together with the conveying wheel, the square aluminum alloy profile is moved out.

[0050] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0051] like Figure 1 As shown, a production process for isothermal extrusion of square aluminum alloy profiles includes the following steps:

[0052] Step 1: Place the round aluminum alloy profile in the feeding box 7 of the processing equipment. Adjust the conveying position of the round aluminum alloy profile by using the feeding box 7 in conjunction with the guide wheels 24 of several sets of limit blocks 9, and transfer the round aluminum alloy profile onto the conveying wheel 8.

[0053] Step 2: The circular aluminum alloy profile is conveyed into the heating furnace 6 by the conveyor wheel 8, and the circular aluminum alloy profile is heated by the heating furnace 6.

[0054] Step 3: The heated circular aluminum alloy profile is conveyed to the extrusion die 4 by the conveyor roller 8. The limiting side plate 10 and the limiting bottom plate 11 are moved by the adjusting seat 12. The angle of the limiting side plate 10 and the limiting bottom plate 11 is adjusted. The extrusion plate 5 is driven to move down by the hydraulic push rod 17. The circular aluminum alloy profile is isothermally extruded between the extrusion plate 5, the limiting bottom plate 11 and the two sets of limiting side plates 10 to make it into a square tube aluminum alloy profile.

[0055] Step 4: Use the pusher 1 in conjunction with the lifting pusher plate 29 to move the square tube aluminum alloy profile, and use the conveyor roller 8 to remove the square tube aluminum alloy profile from the extrusion die 4.

[0056] To solve the extrusion shaping of different types of square aluminum alloy profiles, such as Figure 3 As shown, when in use, the limiting side plate 10 and the limiting bottom plate 11 are fixed by the docking block 14. The lower insertion rod 26 and the upper insertion rod 27 of the docking block 14 are respectively connected to the slots of the limiting side plate 10 and the limiting bottom plate 11. During the extrusion operation of A-type square tube aluminum alloy profile, the two sets of limiting side plates 10 and limiting bottom plates 11 are kept in a vertical state.

[0057] To solve the extrusion shaping of different types of square aluminum alloy profiles, such as Figure 4 As shown, when the limiting side plate 10 and the limiting bottom plate 11 are in use, under the pressing state of the extrusion plate 5, the motor 19 is started, which drives the lead screw 21 to rotate. The lead screw 21 drives the threaded sliding sleeve 13 to move, and the lifting sleeve 18 of the threaded sliding sleeve 13 drives the limiting bottom plate 11 to move. This causes the limiting bottom plate 11 to drive the two sets of limiting side plates 10, so that the two sets of limiting side plates 10 are in an inclined state, thus completing the shaping operation of the C-shaped square tube aluminum alloy profile.

[0058] To solve the extrusion shaping of different types of square aluminum alloy profiles, such as Figure 6 As shown, when the limiting side plate 10 and the limiting bottom plate 11 are in use, the docking angle between the two sets of limiting side plates 10 and limiting bottom plate 11 is adjusted by the docking block 14, so that the two sets of limiting side plates 10 are symmetrically inclined at the upper end of the limiting bottom plate 11. In this state, the extrusion plate 5 is used to extrude the circular aluminum alloy profile to complete the shaping operation of the B-type square tube aluminum alloy profile.

[0059] To address the reinforcement issues during the shaping of different types of square aluminum alloy profiles, such as... Figure 4 As shown, when the adjusting seat 12 is in use, the lifting sleeve 18 adjusts its height according to the position of the limiting base plate 11. When the pressing plate 5 performs the pressing operation, the four vertical push rods 20 move upward, so that the vertical push rods 20 support and fix the lower part of the limiting base plate 11.

[0060] To address the reinforcement issues during the shaping of different types of square aluminum alloy profiles, such as... Figure 8 As shown, when the extrusion plate 5 is used, the transverse push rod 15 is activated, which drives the side top plate 32 to move horizontally, so that the side top plate 32 is pressed against one side of the limiting side plate 10. When the extrusion plate 5 is pressed down, it assists in supporting the two sets of limiting side plates 10.

[0061] like Figure 5 As shown, when the limit block 9 is in use, the motor and screw drive the threaded sleeve 22, which in turn drives the moving frame 25 to move horizontally. The moving frame 25 then simultaneously drives the three sets of limit blocks 9 to move.

[0062] When in use, the limit block 9 is adjusted by sliding the three sets of limit blocks 9 according to the length of the circular aluminum alloy profile and using the sliding groove on the upper part of the movable frame 25, thereby adjusting the position of the guide wheel 24 on the three sets of limit blocks 9.

[0063] To solve the material layout problem during the shaping of different types of square aluminum alloy profiles, such as Figure 7 As shown, when the pusher 1 is in use, the drive motor 30 drives the gear, and the toothed structure on the surface of the lifting push plate 29 drives the lifting push plate 29 to move up and down, thereby adjusting the position of the lifting push plate 29.

[0064] When in use, the pusher 1 is driven by the movable caster 31, so that the pusher 1 moves on the surface of the pressing base 2. The lifting push plate 29 pushes one end of the square tube aluminum alloy profile, so that the other end of the square tube aluminum alloy profile extends out from the pressing base 2, and moves the square tube aluminum alloy profile out in conjunction with the conveying wheel 8.

[0065] like Figure 2 As shown, the processing equipment includes a fixed base 16. A limit block 9, a heating furnace 6 and an extrusion die 4 are sequentially arranged on the upper end of the fixed base 16. A feeding wheel 8 is movably installed in the middle of the upper end of the fixed base 16. An inclined feeding box 7 is fixedly installed on the outer side surface of the fixed base 16. The extrusion die 4 includes a pressing base 2 and a fixing frame 3. The pressing base 2 is located at the lower end of the fixing frame 3. An extrusion plate 5 is movably installed on the inner side of the fixing frame 3.

[0066] like Figure 3 As shown, the extrusion plate 5 and the fixed frame 3 are driven by a hydraulic push rod 17. Two sets of limiting side plates 10 are movably installed inside the pressing base 2 via a rotating shaft. The two sets of limiting side plates 10 are symmetrically arranged. A limiting base plate 11 is provided at the lower part of the two sets of limiting side plates 10. The limiting side plates 10 and the limiting base plate 11 are fixed by a docking block 14. A transverse push rod 15 is provided on one side of the limiting side plate 10. An adjusting seat 12 is provided at the lower part of the limiting base plate 11. A threaded sliding sleeve 13 that is used in conjunction with the limiting base plate 11 is movably installed at the upper end of the adjusting seat 12.

[0067] like Figure 4 As shown, the threaded sliding sleeve 13 and the limiting base plate 11 are connected by a lifting sleeve 18 and a rotating shaft. The adjusting seat 12 and the threaded sliding sleeve 13 are driven by a screw 21 and a motor 19. Each of the four corners of the adjusting seat 12 is provided with a vertical push rod 20 for use with the limiting base plate 11. There are three sets of limiting blocks 9.

[0068] like Figure 5As shown, the bottom of the limiting block 9 is provided with a movable frame 25. The limiting block 9 and the movable frame 25 are connected by a sliding groove. One end of the limiting block 9 is provided with a guide wheel 24. The inner side of the limiting block 9 is provided with a fastening cap 23. A threaded sleeve 22 is fixedly installed in the middle of the lower end of the movable frame 25.

[0069] like Figure 6 As shown, a lower insertion rod 26 and an upper insertion rod 27 are fixedly installed on one side of the docking block 14. The lower insertion rod 26 is located below the upper insertion rod 27. The surfaces of both the lower insertion rod 26 and the upper insertion rod 27 are provided with shafts 28. The side of the limiting base plate 11 is provided with several sets of slots that cooperate with the lower insertion rod 26.

[0070] like Figure 7 As shown, a lifting push plate 29 is movably installed inside the pusher 1, a drive motor 30 is provided between the pusher 1 and the lifting push plate 29, the outer surface of the lifting push plate 29 is provided with tooth grooves, and the lower part of the pusher 1 is provided with movable casters 31.

[0071] like Figure 8 As shown, a limiting side plate 10 is movably installed at one end of the transverse push rod 15. The transverse push rod 15 and the limiting side plate 10 are movably connected through a rotating bracket. The extrusion plate 5, the two sets of limiting side plates 10 and the limiting bottom plate 11 all have electric heating structures, which enable the aluminum alloy material to be isothermally extruded and shaped.

[0072] Traditional iron removal devices, the specifications of square aluminum alloy profiles are as follows: Figure 9 As shown, there are multiple specifications, and the above process cannot be arbitrarily adjusted according to the structural characteristics of the square tube aluminum alloy profile, which means that it can only process one type of square tube aluminum alloy profile, resulting in a single function.

[0073] Therefore, by setting up the adjusting seat 12 and the docking block 14, during the production process of this isothermal extruded square aluminum alloy profile, in conjunction with the use of two sets of limiting side plates 10 and limiting bottom plates 11, it has an adjustable isothermal extrusion shaping structure, which can meet the requirements. Figure 9 The extrusion and shaping of square aluminum alloy profiles of any shape in China expands the applicability of this production process;

[0074] During operation, there are three processing states. In state one, the processing of A-type square tube aluminum alloy profiles, the limiting side plate 10 and the limiting bottom plate 11 are fixed by the docking block 14. The lower insertion rod 26 and the upper insertion rod 27 of the docking block 14 are respectively docked with the grooves of the limiting side plate 10 and the limiting bottom plate 11, so that the two sets of limiting side plates 10 and limiting bottom plates 11 are kept perpendicular after docking. At this time, the heated circular aluminum alloy profile is placed between the two sets of limiting side plates 10 and limiting bottom plates 11, and the extrusion plate 5 is used to extrude the circular aluminum alloy profile from above to complete the shaping operation of A-type square tube aluminum alloy profile. State 2: Processing of C-shaped square aluminum alloy profiles. Based on the processing of A-shaped square aluminum alloy profiles, the processing of C-shaped square aluminum alloy profiles is completed by adjusting the angle of the two sets of limiting side plates 10. During operation, with the extrusion plate 5 under pressure, the motor 19 is started, which drives the lead screw 21 to rotate. The lead screw 21 drives the threaded sliding sleeve 13 to move, and the lifting sleeve 18 of the threaded sliding sleeve 13 drives the limiting base plate 11 to move. This causes the limiting base plate 11 to drive the two sets of limiting side plates 10, making both sets of limiting side plates 10 tilted, thus completing the shaping operation of the C-shaped square aluminum alloy profile. State 3, processing of B-type square tube aluminum alloy profiles: By reinstalling two sets of limiting side plates 10, during operation, the docking angle between the two sets of limiting side plates 10 and the limiting bottom plate 11 is adjusted using the docking block 14, so that the two sets of limiting side plates 10 are symmetrically inclined at the upper end of the limiting bottom plate 11. In this state, the extrusion plate 5 is used to extrude the round aluminum alloy profile, so as to complete the shaping operation of the B-type square tube aluminum alloy profile, thereby completing the isothermal extrusion shaping of various shapes of square tube aluminum alloy profiles and improving its processing flexibility;

[0075] Secondly, the adjustable mold structure can meet the processing operations of different types of square aluminum alloy profiles. However, the stability of the adjustable mold structure is poor during the extrusion and shaping operation, which makes the square aluminum alloy profiles prone to deformation during the shaping process, thus reducing the processing effect of the square aluminum alloy profiles.

[0076] Therefore, by setting a horizontal push rod 15 and a vertical push rod 20, when using the isothermal extrusion square aluminum alloy profile production process, the use of the two sets of limiting side plates 10 and limiting bottom plates 11 can be optimized, the stability of its adjustable mold structure can be improved, deformation of the square aluminum alloy profile can be avoided, and its shaping effect can be improved.

[0077] During operation, when the extrusion plate 5 performs the pressing operation, the four vertical push rods 20 move upward, so that the vertical push rods 20 support and fix the lower part of the limiting base plate 11, improving the structural stability of the limiting base plate 11. Then, the horizontal push rod 15 is activated, so that the horizontal push rod 15 drives the side top plate 32 to move horizontally, so that the side top plate 32 is pressed against one side of the limiting side plate 10. When the extrusion plate 5 presses down, it assists in supporting the two sets of limiting side plates 10. At the same time, the side top plate 32 is connected to the horizontal push rod 15 through the rotating bracket, so that the side top plate 32 can be arbitrarily adjusted according to the angle of the limiting side plate 10, making it suitable for auxiliary support when shaping square tube aluminum alloy profiles of different specifications, completing the reinforcement operation of the two sets of limiting side plates 10 and limiting base plate 11.

[0078] Meanwhile, traditional processes cannot flexibly adapt to aluminum alloy profiles of different lengths, which increases the difficulty of loading and unloading operations and reduces their work efficiency.

[0079] Therefore, by setting up a pusher 1 and a limit block 9, the loading and unloading structure of the isothermal extruded square aluminum alloy profile is optimized during the production process, so that it can be adjusted arbitrarily according to the length of the aluminum alloy raw material, thereby improving the loading and unloading efficiency.

[0080] During operation, the limit blocks 9 can be adjusted by sliding the three sets of limit blocks 9 according to the length of the round aluminum alloy profile using the sliding groove on the upper part of the moving frame 25, thereby adjusting the position of the guide wheels 24 on the three sets of limit blocks 9. When the round aluminum alloy profile is discharged from the feeding box 7, the guide wheels 24 of the three sets of limit blocks 9 can restrict the movement of the round aluminum alloy profile, so that the round aluminum alloy profile falls accurately above the conveying wheel 8. When the pusher 1 is in use, the drive motor 30 drives the gear, and the toothed structure on the surface of the lifting push plate 29 drives the lifting push plate 29 to move up and down. The position of the lifting push plate 29 is adjusted, and the pusher 1 is driven by the moving caster 31, so that the pusher 1 moves on the surface of the pressing base 2. The lifting push plate 29 pushes one end of the square tube aluminum alloy profile, so that the other end of the square tube aluminum alloy profile extends out from the pressing base 2, and moves out of the square tube aluminum alloy profile with the help of the conveying wheel 8.
