[0035] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings. However, the scope of protection of the present invention is not limited to the following description.

[0036] Reference Figures 1-10 As shown, a flat aluminum wire extrusion forming device with multi-point synchronous pressing function includes: a base 1, a feeding unit is provided at one end of the top of the base 1, a cooling unit is provided at the other end of the base 1, and a gantry frame 6 is provided on the base 1, with the gantry frame 6 located between the feeding unit and the cooling unit.

[0037] A cylinder 7 is installed at the top of the gantry frame 6, and a lower mold 28 is installed at the bottom of the inner side of the gantry frame 6. The output end of the cylinder 7 extends into the interior of the gantry frame 6 and is connected to an upper mold 27. Both the lower mold 28 and the upper mold 27 are in contact with the discharge end of the feeding unit.

[0038] The gantry 6 has cylindrical oil tanks 35 arranged on both sides inside. A piston rod 36 is slidably connected to one end of the cylindrical oil tank 35. A pressing plate 37 is connected to one end of the piston rod 36. An oil supply pipe 34 is connected to the other end of the cylindrical oil tank 35. Oil grooves 41 are opened on both sides inside the upper mold 27. Hydraulic oil is arranged inside the oil grooves 41. A connecting rod 42 is set at the bottom of the oil grooves 41. A movable rod 46 is slidably arranged inside the connecting rod 42. An isolation plate 43 is fixedly set inside the oil grooves 41. Pressing rods 40 are set on both sides of the output end of the cylinder 7. One end of the pressing rod 40 extends into the oil groove 41 and is connected to the pressing plate 44. One end of the oil supply pipe 34 is connected to the inside of the oil groove 41. Two air pumps 45 are arranged opposite each other on one side of the upper mold 27. The output end of the air pump 45 extends into the oil groove 41 and is connected to the inside of the connecting rod 42.

[0039] The top of the cylinder 7 is provided with a slide groove 38, and a spring 39 is fixedly installed inside the slide groove 38. The top of the spring 39 is connected to the output end of the cylinder 7.

[0040] This invention provides a technical solution in which plasticized aluminum material is extruded from the outlet at the other end of the feeding cylinder 4 and enters the die extrusion molding stage. The gantry frame 6 is a U-shaped frame welded from structural steel, spanning below the outlet of the feeding cylinder 4. The lower die 28 is a rectangular die block made of alloy steel, with a semi-flat or rectangular cavity at the top, and is fixed to the bottom crossbeam of the gantry frame 6 by bolts. A cylinder 7 is fixed to the center of the top of the gantry frame 6 via a flange. The cylinder 7 is a double-acting standard cylinder or servo cylinder, vertically arranged with the piston rod pointing downwards. The piston rod end of the cylinder 7 extends into the interior of the gantry frame 6. The upper die 27 is a rectangular die block made of alloy steel, with another half-cavity at the bottom that mates with the cavity of the lower die 28. The discharge port of the feeding cylinder 4 is located above one end of the cavity of the lower mold 28 and is connected to the mold cavity between the upper mold 27 and the lower mold 28. The cavity at the bottom of the upper mold 27 and the cavity at the top of the lower mold 28 are closed, and the plasticized aluminum material is wrapped in the cavity after the mold is closed. The aluminum material is extruded into a flat aluminum wire cross-section shape by the upper and lower molds.

[0041] The cylindrical oil tank 35 is made of cylindrical steel pipe, arranged horizontally, with one end fixed to the side wall of the gantry 6 via a bracket. The piston rod 36 is made of round steel, with piston rings embedded in its outer wall, forming a sliding seal with the inner wall of the cylindrical oil tank 35. A return spring is fixedly installed at the bottom of the cavity in the retraction direction of the piston rod 36 at the other end of the cylindrical oil tank 35. The return spring is a cylindrical helical compression spring, with one end fixed to the end wall of the cylindrical oil tank 35 and the other end fixed to the end face of the piston rod 36. The return spring causes the piston rod 36 to automatically retract to its original position after the hydraulic oil pressure is lost. An oil supply pipe 34 is connected to the other end of the cylindrical oil tank 35 near the return spring. The oil supply pipe 34 is made of pressure-resistant steel pipe, with one end communicating with the internal oil cavity of the cylindrical oil tank 35.

[0042] Hydraulic oil is pre-filled inside the oil tank 41. A connecting rod 42, made of round steel pipe, is fixedly installed at the bottom of the oil tank 41. The connecting rod 42 is vertically arranged and welded to the bottom of the oil tank 41, forming a sealed air chamber inside. A movable rod 46, made of round steel pipe, is slidably installed inside the connecting rod 42. The movable rod 46 has a sealing ring embedded in its outer wall, forming a sliding seal with the inner wall of the connecting rod 42. It can slide up and down along the axial direction of the connecting rod 42. An isolation plate 43, made of steel plate, is fixedly installed inside the oil tank 41. It is horizontally arranged in the upper middle part of the oil tank 41, dividing the interior of the oil tank 41 into upper and lower chambers. A through hole for the movable rod 46 to pass through is opened on the isolation plate 43. A sealing ring is embedded in the inner wall of the through hole, forming a sliding seal with the movable rod 46. The pressing rod 40, made of round steel pipe, is vertically arranged. Its upper end is fixedly connected to the flange on the side of the output end of the cylinder 7, and its lower end extends into the interior of the oil tank 41, located above the isolation plate 43. A pressing plate 44 is fixedly connected to the lower end of the pressing rod 40. The pressing plate 44 is made of rectangular steel plate, and a sealing ring is embedded in the outer wall to form a sliding seal with the inner wall of the upper cavity of the oil tank 41. The other end of the oil delivery pipe 34 is connected to the side wall of the lower cavity of the oil tank 41. Two air pumps 45 are arranged opposite each other on one side of the upper mold 27. The air pumps 45 are small diaphragm air pumps, which are fixed to the side wall of the upper mold 27 by a bracket. The output end of the air pump 45 extends into the interior of the oil tank 41 through a pressure-resistant hose and is connected to the bottom air chamber of the sleeve rod 42.

[0043] During mold closing, cylinder 7 begins to descend, simultaneously activating two air pumps 45. Air pumps 45 inflate the internal air chamber of the connecting rod 42, compressing the gas and pushing the movable rod 46 upwards out of the connecting rod 42, passing through the through hole of the partition plate 43. The top of the movable rod 46 rests against the bottom surface of the pressing plate 44. At this time, the movable rod 46 remains extended, holding the pressing plate 44 and the pressing rod 40 upwards. Since the upper end of the pressing rod 40 is fixedly connected to the output end of cylinder 7, when cylinder 7 presses downwards, the movable rod 46 and the pressing rod 40 abut against each other, preventing the pressing plate 44 from moving downwards. Thus, cylinder 7 can drive the upper mold 27 to move downwards as a whole, closing the mold. Through the pneumatic pre-fixing mechanism, the pressing rod 40 and the movable rod 46 are locked together during mold closing, ensuring that the upper mold 27 can descend smoothly and close with the lower mold 28.

[0044] Then, after the upper mold 27 and the lower mold 28 are fully closed, the air pump 45 stops charging and switches to exhaust mode. The gas in the air chamber inside the sleeve rod 42 is discharged, the movable rod 46 loses its air pressure support, and retracts into the sleeve rod 42 under its own weight. The bottom of the pressing plate 44 loses its support, the cylinder 7 continues to extend downward, and the output end of the cylinder 7 enters the slide groove 38, compressing the spring 39. The spring 39 is compressed into the slide groove 38, playing a buffering role. At the same time, the pressing rod 40 drives the pressing plate 44 to move downward. The pressing plate 44 presses the movable rod 46 downward, and the movable rod 46 is pressed into the sleeve rod 42. The end of the movable rod 46 pushes the hydraulic oil in the lower chamber of the oil tank 41 downward. After being pressurized, the hydraulic oil enters the interior of the cylindrical oil tank 35 through the oil supply pipe 34. After the hydraulic oil enters the cylindrical oil tank 35, it pushes the piston rod 36 to extend outward, causing the extrusion plate 37 to move towards the mold. Ultimately, the two extrusion plates 37 clamp and fix the upper mold 27 and the lower mold 28 from both sides. Through the multi-point synchronous hydraulic clamping mechanism, the two sides of the mold are rigidly fixed after the mold is closed, preventing the upper mold 27 and the lower mold 28 from horizontally shifting or opening due to the high pressure extrusion of the aluminum material after the mold is closed.

[0045] After extrusion molding and cooling are completed, cylinder 7 retracts upward, driving the upper mold 27 to move upward and open. At this time, the return spring inside the cylindrical oil tank 35 pushes the piston rod 36 to retract back to its original position, pushing the hydraulic oil back into the oil groove 41, and the extrusion plate 37 returns to its original position. At the same time, the spring 39 in the slide 38 resets, pushing the output end of cylinder 7 upward out of the slide 38, assisting the upper mold 27 to quickly return to its original position.

[0046] Preferably, the feeding unit includes a feeding cylinder 4 fixedly installed on the top of the base 1, a conveying screw 19 rotatably installed inside the feeding cylinder 4, and a drive assembly installed on the top of one end of the base 1. A feeding box 5 is provided on the top of one end of the feeding cylinder 4, and a discharge port is provided at the bottom of the other end of the feeding cylinder 4. The discharge port contacts the upper mold 27 and the lower mold 28. An electric heating wire is provided on the inner wall of the feeding cylinder 4.

[0047] The drive assembly includes a motor base 2 mounted on the top of one end of the base 1, a first motor 3 mounted on the motor base 2, a large gear 23 and a small gear 24 rotatably mounted on one end of the feed cylinder 4, the small gear 24 meshing with the large gear 23, the large gear 23 being fixedly connected to one end of the conveying screw 19, a second drive shaft 22 mounted on the output end of the first motor 3, the second drive shaft 22 being connected to the small gear 24, a feeding assembly mounted inside the feed box 5, the feeding assembly being connected to the second drive shaft 22, a protective shell 18 mounted on one end of the feed cylinder 4, and the large gear 23 and the small gear 24 being arranged inside the protective shell 18.

[0048] Specifically, a motor base 2 is bolted to one end of the base 1. The motor base 2 is made of cast iron or welded steel plate. A first motor 3 is bolted to the motor base 2. The first motor 3 is a three-phase asynchronous motor or a servo motor. The output end of the first motor 3 is fixedly connected to a second drive shaft 22 via a coupling. The second drive shaft 22 is made of round steel. A fourth pulley 25 is fixedly sleeved on the second drive shaft 22. The fourth pulley 25 is fixed to the second drive shaft 22 via a flat key. A third synchronous belt 21, made of rubber, is sleeved on both the third pulley 20 and the fourth pulley 25.

[0049] After the aluminum raw material enters the conveying cylinder 4, it undergoes plasticizing and extrusion conveying. The conveying cylinder 4 is a cylindrical structure made of alloy steel and is fixed to one end of the base 1 by a bracket. Inside the conveying cylinder 4, a conveying screw 19 is rotatably mounted via bearings. The conveying screw 19 is a variable pitch or constant pitch screw made of alloy steel. One end is supported on the end cap of the conveying cylinder 4 by a bearing, and the other end extends out of the end of the conveying cylinder 4. An electric heating wire is embedded or wound on the inner wall of the conveying cylinder 4. The electric heating wire is made of nickel-chromium alloy resistance wire and is isolated from the inner wall of the conveying cylinder 4 by a high-temperature resistant insulation layer. After being powered on, the aluminum material inside the conveying cylinder 4 is heated. A large gear 23, a cylindrical spur gear, is fixedly connected to one end of the conveying screw 19 extending from the conveying cylinder 4. The small gear 24, also a cylindrical spur gear, is fixed to the second drive shaft 22 via a key. The protective shell 18, a rectangular cover welded from steel plates, encloses the large gear 23 and small gear 24. This enclosure prevents dust and foreign objects from entering the gear meshing area and avoids accidents caused by operators touching the rotating gears. During operation, the first motor 3 drives the second drive shaft 22 to rotate. The second drive shaft 22, through the small gear 24, drives the large gear 23 to rotate at a reduced speed. The large gear 23 then drives the conveying screw 19 to rotate inside the conveying cylinder 4. The aluminum raw material moves forward under the propulsion of the spiral blades of the conveying screw 19, and is gradually compacted and plasticized by the squeezing and shearing forces between the conveying screw 19 and the inner wall of the conveying cylinder 4. The electric heating wire generates heat when energized, and the heat is conducted to the aluminum material through the inner wall of the feed cylinder 4, raising the temperature of the aluminum material to an extrudable state. Through the screw extrusion plasticizing mechanism, the aluminum material gradually changes from a solid state to a fluid plasticized state under the mechanical extrusion and shearing of the conveying screw 19 and the thermal effect of the electric heating wire, preparing it for subsequent extrusion molding.

[0050] Preferably, the feeding assembly includes two feed rollers 16 arranged rotatably at both ends inside the feed box 5, a first drive shaft 17 rotatably disposed on one side of the feed box 5, and two drive gears 26 rotatably disposed on the other side of the feed box 5.

[0051] Two transmission gears 26 mesh with each other and are fixedly connected to one end of two feeding rollers 16 respectively. One end of the first transmission shaft 17 is connected to a third pulley 20, and one end of the second transmission shaft 22 is fitted with a fourth pulley 25. The third pulley 20 and the fourth pulley 25 are together fitted with a third synchronous belt 21.

[0052] Specifically, the feeding roller 16 is a cylindrical roller made of round steel, supported at both ends by bearings on the side walls of the feed box 5, and can rotate around its own axis. Two transmission gears 26 are fixedly connected to the same end of each of the two feeding rollers 16. The transmission gears 26 are cylindrical spur gears, and the two transmission gears 26 mesh with each other. A first transmission shaft 17 is fixedly connected to the other end of one of the feeding rollers 16. The first transmission shaft 17 is made of round steel and extends horizontally out of the outer wall of one side of the feed box 5. A third pulley 20 is fixedly connected to the extended end of the first transmission shaft 17. The third pulley 20 is a cast iron pulley and is fixed to the first transmission shaft 17 by a flat key.

[0053] The first motor 3 drives the second transmission shaft 22 and the fourth pulley 25 to rotate. The fourth pulley 25 drives the third pulley 20 and the first transmission shaft 17 to rotate via the third synchronous belt 21. The first transmission shaft 17 drives one of the feeding rollers 16 to rotate. The feeding roller 16 drives the other feeding roller 16 to rotate in the opposite direction via the transmission gear 26. The two feeding rollers 16 rotate relative to each other, quantitatively feeding the aluminum raw material in the feed box 5 into the conveying cylinder 4 below. The relatively rotating feeding mechanism achieves uniform quantitative supply of aluminum raw material, avoiding raw material accumulation and blockage or excessive feeding at one time.

[0054] Preferably, the cooling unit includes a cooling box 8 disposed at the other end of the top of the base 1, a conveying assembly disposed inside the cooling box 8, a water distribution pipe 29 disposed inside one end of the cooling box 8, water spray pipes 30 disposed at both ends of the water distribution pipe 29, and a plurality of nozzles 31 disposed at the bottom of the water spray pipes 30. A water inlet pipe 9 is disposed at the top of one end of the cooling box 8, and one end of the water inlet pipe 9 is connected to the water distribution pipe 29.

[0055] The cooling unit also includes a jet box 32 fixedly installed inside the other end of the cooling box 8 and a fan 10 fixedly installed on the top of the other end of the cooling box 8. The air outlet of the fan 10 extends into the interior of the jet box 32, and multiple air outlets are provided at the bottom of the jet box 32.

[0056] Specifically, the formed flat aluminum wire is extruded from the other end of the mold and enters the cooling and shaping stage. The cooling box 8 is a rectangular box made of welded steel plates, with an open top or a cover plate, forming a cooling chamber inside. The water distribution pipe 29 is made of steel or PVC pipe and is horizontally arranged at the top inside the cooling box 8. The water spray pipe 30 is made of steel or flexible hose and is arranged along the length of the cooling box 8. Multiple nozzles 31 are arranged sequentially along the length of the bottom of the water spray pipe 30. The nozzles 31 are fan-shaped or conical nozzles and are connected to the water spray pipe 30 via pipe threads. The water inlet pipe 9 is made of steel or flexible hose, with its upper end connected to the workshop cooling water system or water pump, and its lower end connected to the middle of the water distribution pipe 29. During operation, cooling water enters the water distribution pipe 29 from the water inlet pipe 9, flows to the water spray pipes 30 on both sides, and sprays downwards from each nozzle 31, forming a uniform water curtain covering the surface of the flat aluminum wire extruded from the mold. The spray cooling mechanism rapidly cools and shapes the high-temperature flat aluminum wire.

[0057] To further remove residual moisture from the surface of the flat aluminum wire, air drying is performed. The air jet box 32 is a flat box made of rectangular steel pipes or steel plates, with an open bottom or multiple air outlets. A fan 10 is fixedly installed at the top of the other end of the cooling box 8. The fan 10 is a centrifugal or axial fan, fixed to the top of the cooling box 8 by a bracket. The air outlet of the fan 10 extends into the interior of the air jet box 32 through an air duct or flange. During operation, the fan 10 starts, drawing in and pressurizing outside air before sending it into the air jet box 32. The air is then blown downwards from the multiple air outlets at the bottom of the air jet box 32, forming a high-speed airflow that blows onto the surface of the flat aluminum wire after passing through the rear section of the cooling box 8, blowing off any adhering water droplets. This air-drying mechanism achieves rapid drying of the flat aluminum wire.

[0058] Preferably, the conveying assembly includes multiple conveying rollers 33 rotatably disposed at the bottom of the cooling box 8, multiple second pulleys 14 rotatably disposed on one side of the cooling box 8, a second motor 11 fixedly disposed at the top of one end of the cooling box 8, a first pulley 12 connected to the output end of the second motor 11, a first synchronous belt 13 sleeved on the first pulley 12, and multiple second synchronous belts 15, one end of the first synchronous belt 13 being sleeved on one of its second pulleys 14;

[0059] Two adjacent second pulleys 14 are connected together to a second synchronous belt 15, and one end of the second pulley 14 is fixedly connected to one end of the conveyor roller 33.

[0060] Specifically, the conveyor rollers 33 are cylindrical rollers made of round steel or steel pipes, with both ends rotatably connected to the side walls of the cooling box 8 via bearing seats. They are arranged at equal intervals along the length of the cooling box 8. Multiple second pulleys 14, made of cast iron, are rotatably mounted on one outer wall of the cooling box 8 via bearings. A second motor 11, a three-phase asynchronous motor or a geared motor, is fixedly mounted on the top of one end of the cooling box 8 via a bracket. The output end of the second motor 11 is fixedly connected to a first pulley 12, which is fixed to the output shaft of the second motor 11 via a key. A first synchronous belt 13, made of rubber, is fitted onto the first pulley 12. The other end of the first pulley 12 is fitted onto one of the second pulleys 14 closest to the end of the cooling box 8. A second synchronous belt 15, also made of rubber, is fitted between two adjacent second pulleys 14. One end of each second pulley 14 is fixedly connected to one end of the corresponding conveyor roller 33 via a coupling or a key. During operation, the second motor 11 is started, which drives the first pulley 12 to rotate. The first pulley 12 drives the first second pulley 14 to rotate via the first synchronous belt 13. The second pulley 14 drives the adjacent second second pulley 14 to rotate via the second synchronous belt 15, and so on. All the second pulleys 14 and the conveying rollers 33 rotate synchronously, conveying the flat aluminum wire in the cooling box 8 forward. The synchronous belt linkage mechanism enables the synchronous drive of multiple conveying rollers 33, ensuring the smoothness and continuity of the flat aluminum wire conveying.
