Description

Technical Field

[0001] This invention relates to the field of automotive sunroof trim processing technology, specifically an extrusion molding equipment for aluminum alloy automotive sunroof T-shaped trim. Background Technology

[0002] The car sunroof consists of laminated tempered glass, aluminum alloy T-shaped pressure strips and EPDM sealing strips, and an aluminum sliding rail frame. It is opened and closed by motor drive. The edge aluminum pressure strips clamp the sealing strips to complete waterproofing and water diversion, while also providing ventilation and lighting, and optimizing the ventilation inside the car.

[0003] The T-shaped aluminum alloy strip for car sunroofs uses aluminum rods as raw materials. After the raw materials are heated and softened, they are fed into an aluminum profile extrusion press. Under high pressure, they are extruded into a whole shape through a T-shaped section die in one go. Then, they are cooled, straightened, aged, and finished to obtain the finished profile.

[0004] After the aforementioned strip is extruded and formed, it is conveyed to the cooling area using rollers. Air cooling is usually used to cool the strip. Air cooling is achieved by continuously blowing air onto the strip from one direction using a fan. However, since the strip is T-shaped, some of the airflow is blocked by the surface of the strip when it comes into contact with the airflow blown by the fan, which reduces the cooling effect.

[0005] Therefore, an extrusion molding equipment for aluminum alloy automotive sunroof T-shaped strips is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: An extrusion forming equipment for an aluminum alloy automotive sunroof T-shaped strip, comprising an aluminum profile extruder, wherein a discharge port is provided at the end of the aluminum profile extruder; a conveyor frame is provided on the side wall of the aluminum profile extruder; multiple rollers are installed inside the conveyor frame; multiple mounting plates are provided in the middle of the conveyor frame; the mounting plates are located between the multiple rollers; a cooling ring is provided on the top of the mounting plate; an air guide pipe is fixedly connected to the side wall of the cooling ring; multiple air jets are provided in the middle of the cooling ring and face the discharge port and are inclined; the cooling ring is connected to the mounting plate via a disassembly assembly; the air guide pipe and the multiple air jets are in communication.

[0008] Preferably, the cooling ring sidewall is fixedly connected to a plurality of fixing rods; an air guide shroud is fixedly connected to the end of each fixing rod; and the air guide shroud is sloped in the middle.

[0009] Preferably, the disassembly assembly includes multiple insertion rods; the insertion rods are fixedly connected to the cooling ring; the insertion rods are slidably fitted to the mounting plate; a connecting groove is provided in the middle of the insertion rod; multiple straps are fixedly connected to the bottom of the conveyor frame; a ring is fixedly connected to the end of the strap; multiple limiting rods are fixedly connected to the side wall of the conveyor frame; the ring is slidably fitted to the limiting rod.

[0010] Preferably, the bottom of the conveyor frame is fixedly connected to multiple upright plates; the straps are slidably connected in the middle of the upright plates; a spring is fixedly connected in the middle of the upright plates; and the spring is sleeved on the surface of the straps.

[0011] Preferably, an elastic piece is fixedly connected inside the strap; the elastic piece is open and located between the strap and the connecting groove.

[0012] Preferably, the top of the conveyor frame is fixed with multiple retaining rings; the air guide pipe is located inside the retaining rings.

[0013] Preferably, the inner wall of the air guide shroud is fixedly connected to an intercepting cloth; the end of the intercepting cloth and the side wall of the cooling ring are fixedly connected.

[0014] Preferably, a plurality of guide plates are fixedly connected to the top of the mounting plate; the ends of the guide plates are arc-shaped and the insert rods are slidably fitted inside the guide plates.

[0015] The advantages of this invention are: 1. The extrusion molding equipment for aluminum alloy automotive sunroof T-shaped pressure strips of the present invention can continuously cool the material as it passes through by adding multiple cooling rings. At the same time, the material passes through the middle of the cooling rings, so when the material passes through, a ring of air jets will blow air from multiple directions at the same time, thereby increasing the contact between the gas and the material surface and accelerating the cooling speed of the material. In addition, the air jets are set at an angle, which can reduce the movement resistance of the airflow when it comes into contact with the material, and accelerate the airflow carrying heat away from the material surface.

[0016] 2. The extrusion molding equipment for an aluminum alloy automotive sunroof T-shaped pressure strip of the present invention can intercept hot air by adding a wind guide shroud, reducing the direct contact between hot air and the cooling ring. At the same time, the inclined surface of the wind guide shroud can guide the gas in contact. When the gas is guided to move to both sides, the time the gas stays on the surface of the wind guide shroud can be reduced. At the same time, when the gas moves on the wind guide shroud, the surface of the wind guide shroud can also be used to dissipate heat, thereby reducing the heat of the gas.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Specific implementation examples are given below.

[0022] like Figures 1 to 7As shown in the embodiment of the present invention, an extrusion forming equipment for an aluminum alloy automotive sunroof T-shaped strip includes an aluminum profile extrusion press 1, with a discharge port 11 at one end; a conveyor frame 12 is provided on the side wall of the aluminum profile extrusion press 1; multiple rollers 13 are installed inside the conveyor frame 12; multiple mounting plates 14 are provided in the middle of the conveyor frame 12; the mounting plates 14 are located between the multiple rollers 13; a cooling ring 15 is provided on the top of the mounting plate 14; and an air guide pipe 16 is fixedly connected to the side wall of the cooling ring 15. The cooling ring 15 has multiple air jet holes 17 in the middle, facing the discharge port 11 and inclined; the cooling ring 15 is connected to the mounting plate 14 via a disassembly assembly 18; the air guide pipe 16 and the multiple air jet holes 17 are connected; during operation, when the pressure strip is extruded by the aluminum profile extruder 1, it will be discharged from the discharge port 11, and after discharge, it will move onto the idler roller 13. At this time, the idler roller 13 will transport the formed long strip material. During the transport, the air pump connected to the air guide pipe 16 is turned on, and after being turned on, the gas is sent from the air guide pipe 16 to the air pump 17. The material is transported inside the cooling ring 15 and then ejected through the jet holes 17. As the material passes through, the jet holes 17 make multi-directional contact with the material, carrying away heat from the material surface. As the material moves on the multiple rollers 13, it passes sequentially through the middle of the multiple cooling rings 15, continuously cooling the material during this process. After use, the material can be removed using the disassembly assembly 1. 8. Disassemble the cooling ring 15 and inspect its internal structure. By adding multiple cooling rings 15, the material can be continuously cooled as it passes through. Since the material passes through the middle of the cooling ring 15, the jet holes 17 will blow air from multiple directions simultaneously as the material passes through, thereby increasing the contact between the gas and the material surface and accelerating the cooling speed of the material. At the same time, the jet holes 17 are set at an angle, which can reduce the movement resistance of the airflow when it comes into contact with the material, and accelerate the airflow carrying heat away from the material surface.

[0023] like Figures 3 to 7As shown, multiple fixing rods 2 are fixed to the side wall of the cooling ring 15; an air guide shroud 21 is fixed to the end of each fixing rod 2; the air guide shroud 21 has a sloping middle section; during operation, when the gas blown by the jet nozzle 17 comes into contact with the material, because the jet nozzle 17 is sloping, the gas will continue to move forward after being blown. At this time, the gas blown by the current jet nozzle 17 will come into contact with the next jet nozzle 17. When they come into contact, they will be blocked by the air guide shroud 21. When the gas comes into contact with the air guide shroud 21, it will move to both sides along the sloping middle section of the air guide shroud 21. When the shroud 21 moves away from the cooling ring 15, the gas carrying heat will leave the surface of the cooling ring 15, thereby guiding the hot gas and reducing its contact with the cooling ring 15. By adding the air guide shroud 21, the hot gas can be intercepted, reducing the direct contact between the hot gas and the cooling ring 15. At the same time, the inclined surface of the air guide shroud 21 can be used to guide the gas in contact. When the gas is guided to move to both sides, the time the gas stays on the surface of the air guide shroud 21 can be reduced. At the same time, when the gas moves on the air guide shroud 21, the surface of the air guide shroud 21 can be used to dissipate heat, thereby reducing the heat of the gas.

[0024] like Figures 2 to 6 As shown, the disassembly assembly 18 includes multiple insertion rods 3; the insertion rods 3 are fixedly connected to the cooling ring 15; the insertion rods 3 are slidably fitted onto the mounting plate 14; a connecting groove 31 is provided in the middle of the insertion rod 3; multiple straps 32 are fixedly connected to the bottom of the conveyor frame 12; a ring 33 is fixedly connected to the end of the strap 32; multiple limiting rods 34 are fixedly connected to the side wall of the conveyor frame 12; the ring 33 is slidably fitted onto the limiting rod 34; during operation, when it is necessary to remove the cooling ring 15, first remove the ring 33 from the limiting rod 34. After removal, the straps 32 will loosen, and at this time, the straps 32 will leave the inside of the connecting groove 31. Then, the insertion rods 3 can be pulled out from the inside of the mounting plate 14. When installing, first insert the insertion rods 3 into the inside of the mounting plate 14 so that the bottom of the cooling ring 15 contacts the mounting plate 14. The support is provided, and then the strap 32 is moved from the bottom of the insertion rod 3 to the inside of the connecting groove 31. After moving into the connecting groove 31, the ring 33 is pulled to tighten the strap 32. Finally, it is put onto the limiting rod 34. Since the strap 32 passes through its own middle inside the connecting groove 31, it forms a circle and fits into the connecting groove 31. Therefore, when the ring 33 is tightened, the strap 32 will be in close contact with the connecting groove 31 to complete the fixation. By making the cooling ring 15 detachable, the cooling ring 15 can be disassembled after multiple uses to inspect the damage to the cooling ring 15 caused by high temperature, thereby increasing the convenience of the maintenance of the cooling ring 15. At the same time, the strap 32 can be tightened to fix the insertion rod 3 when it is fixed by the loop formed by itself.

[0025] like Figure 4As shown, the bottom of the conveyor frame 12 is fixedly connected to multiple upright plates 4; the strap 32 is slidably connected to the middle of the upright plate 4; a spring 41 is fixedly connected to the middle of the upright plate 4; the spring 41 is sleeved on the surface of the strap 32; during operation, when the ring 33 leaves the limiting rod 34, the strap 32 will rebound due to the force generated when it is pulled, thus sliding in the middle of the upright plate 4. When it rebounds, the ring 33 will contact the spring 41, and at this time the ring 33 will be tightly attached to the spring 41. At the same time as the strap 32 rebounds, the ring 33 will be driven. At this time, the ring 33 will push the spring 41 after contacting it during movement, causing the spring 41 to be compressed; by adding the spring 41, the ring 33 can be restricted when the strap 32 drives the ring 33 to move. After being restricted, the ring 33 will stay on the spring 41, and the position of the spring 41 will be fixed. Thus, every time the strap 32 is unlocked, the ring 33 will be restricted by the upright plate 4 and stay on the spring 41.

[0026] like Figure 6 As shown, an elastic piece 5 is fixedly connected inside the strap 32; the elastic piece 5 is open and located between the strap 32 and the connecting groove 31; during operation, after the strap 32 is unlocked, as the strap 32 gradually loosens, the loop formed in the middle of the strap 32 will be stretched open by the elastic piece 5, thereby accelerating the opening of the loop in the middle of the strap 32 after the strap 32 is unlocked and loosened. When the strap 32 is quickly stretched open, it will accelerate the speed at which it leaves the connecting groove 31; by adding the elastic piece 5, the loop in the middle of the strap 32 can be opened faster after the strap 32 is loosened, thereby accelerating the exit of the strap 32 from the connecting groove 31 and the unlocking rod 3. At the same time, the elastic piece 5 is open, so it can adapt to the locking state of the strap 32 when the strap 32 is tightened, thereby reducing the impact on the locking of the strap 32.

[0027] like Figures 1 to 3 As shown, a plurality of fixing rings 6 are fixedly connected to the top of the conveying frame 12; the air guide pipe 16 is located inside the fixing ring 6; during operation, before the air guide pipe 16 is connected to the cooling ring 15, the air guide pipe 16 can be inserted into the fixing ring 6 first, and after insertion, the air guide pipe 16 can be restricted between the fixing ring 6 and the conveying frame 12; by adding the fixing ring 6, the air guide pipe 16 can be restricted between the conveying frame 12 and the fixing ring 6, thereby increasing the stability of the air guide pipe 16 during gas transmission.

[0028] like Figure 7As shown, an intercepting cloth 7 is fixedly connected to the inner wall of the air guide shroud 21; the end of the intercepting cloth 7 is fixedly connected to the side wall of the cooling ring 15; during operation, when the material is being cooled, fine aluminum powder will appear on the surface, which will be carried by the gas. As the material moves with the gas, the powder that moves between the cooling ring 15 and the air guide shroud 21 will be intercepted by the intercepting cloth 7; by adding the intercepting cloth 7, an interceptor can be added between the air guide shroud 21 and the cooling ring 15, reducing the amount of aluminum powder moving between the air guide shroud 21 and the cooling ring 15, thereby reducing the damage to the cooling ring 15 caused by long-term adhesion of aluminum powder, and also increasing the convenience of cleaning the cooling ring 15.

[0029] like Figures 3 to 4 As shown, a plurality of guide plates 8 are fixedly connected to the top of the mounting plate 14; the ends of the guide plates 8 are arc-shaped and the insertion rod 3 is slidably fitted inside the guide plates 8; during operation, when the insertion rod 3 is inserted into the mounting plate 14 and contacts the guide plate 8, it will be guided by the arc shape of the end of the guide plate 8, thereby increasing the guidance of the insertion rod 3 into the mounting plate 14; by adding the guide plates 8, it is possible to guide the insertion rod 3 when it is inserted crookedly into the mounting plate 14, thereby increasing the guidance of the insertion rod 3 into the mounting plate 14.

[0030] Working principle: After the pressure strip is extruded by the aluminum profile extruder 1, it will be discharged from the discharge port 11. After discharge, it will move to the idler roller 13. At this time, the idler roller 13 will convey the formed long strip material. During the conveying, the air pump connected to the air guide pipe 16 will be turned on. After being turned on, the air will be transmitted from the air guide pipe 16 to the inside of the cooling ring 15. After being transmitted to the inside of the cooling ring 15, it will be sprayed out through the air jet hole 17. At this time, the air jet hole 17 will make multi-directional contact with the material as the material passes by. When the air jet hole 17 contacts the material, it will make multi-directional contact with the material, thereby carrying away the heat from the surface of the material. When the material moves on multiple idler rollers 13, it will pass through the middle of multiple cooling rings 15 in sequence. During transit, multiple cooling rings 15 continuously cool the material. After use, the cooling rings 15 can be disassembled using the disassembly assembly 18 for internal inspection. When the gas blown by the jet nozzle 17 comes into contact with the material, because the jet nozzle 17 is inclined, the gas continues to move forward after being blown. At this time, the gas blown by the current jet nozzle 17 will come into contact with the next jet nozzle 17. When they come into contact, they will be blocked by the air guide shroud 21. When the gas comes into contact with the air guide shroud 21, it will move to both sides along the inclined surface in the middle of the air guide shroud 21. When the gas moves along the air guide shroud 21, it will move away from the cooling ring 15. At this time, the gas carrying heat will leave the surface of the cooling ring 15, thereby guiding the hot gas and reducing its contact with the cooling ring 15. To remove the cooling ring 15, first remove the ring 33 from the limiting rod 34. After removal, the strap 32 will loosen and will leave the connecting groove 31. Then, pull the insert rod 3 out of the mounting plate 14. For installation, first insert the insert rod 3 into the mounting plate 14, ensuring the bottom of the cooling ring 15 contacts the mounting plate 14 for support. Then, slide the strap 32 from the bottom of the insert rod 3 into the connecting groove 31. After moving it into the connecting groove 31, pull the ring 33 to tighten the strap 32. Finally, slide it onto the limiting rod 34. Because the strap 32 passes through its center inside the connecting groove 31, it forms a loop and fits into the groove. When the ring 33 is tightened, the strap 32 will be tightly attached to the connecting groove 31 to complete the fixation; when the ring 33 leaves the limiting rod 34, the strap 32 will rebound due to the force generated when it is pulled and slide in the middle of the upright plate 4. When it rebounds, the ring 33 will contact the spring 41. At this time, the ring 33 will be tightly attached to the spring 41. When the strap 32 rebounds, the ring 33 will be moved. When the ring 33 moves and contacts the spring 41, it will push the spring 41 and compress the spring 41; after the strap 32 is unlocked, as the strap 32 gradually loosens, the loop formed in the middle of the strap 32 will be stretched open by the elastic plate 5. Thus, after the strap 32 is unlocked and loosened, the opening of the loop in the middle of the strap 32 is accelerated. When the strap 32 is quickly stretched open, it will accelerate the speed at which it leaves the connecting groove 31.Before connecting the air guide pipe 16 and the cooling ring 15, the air guide pipe 16 can be inserted into the fixed ring 6. After insertion, the air guide pipe 16 can be confined between the fixed ring 6 and the conveyor frame 12. When the material is being cooled, fine aluminum powder will appear on the surface. This powder will be carried by the gas. As the material moves with the gas, the powder that moves between the cooling ring 15 and the air guide shroud 21 will be intercepted by the intercepting cloth 7. When the insert rod 3 is inserted into the mounting plate 14 and contacts the guide plate 8, it will be guided by the arc shape at the end of the guide plate 8, thereby increasing the guidance of the insert rod 3 into the mounting plate 14.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
