Description

Technical Field

[0001] This application relates to the field of aluminum profile production equipment technology, and in particular to a multi-cavity die head linkage aluminum profile extrusion molding device. Background Technology

[0002] In modern manufacturing, aluminum alloy profiles are widely used in numerous fields such as construction, transportation, and electronics due to their excellent properties, including lightweight, high strength, and corrosion resistance. The production and processing of aluminum alloy profiles requires an aluminum extrusion molding device. Workers place the aluminum billet into the extrusion molding cavity of the device, then control the extrusion die to descend vertically into the cavity. The force applied by the extrusion die extrudes the aluminum billet into an aluminum profile.

[0003] In existing technologies, most traditional aluminum profile extrusion molding equipment adopts single-cavity, single-die extrusion molding, which can only extrude one aluminum profile at a time, resulting in low work efficiency and high labor intensity for workers. With the improvement of equipment, some multi-cavity, multi-die aluminum profile extrusion molding equipment has appeared on the market. Although it can extrude multiple aluminum profiles simultaneously, multi-cavity, multi-die aluminum profile extrusion molding equipment usually uses multiple cylinders or hydraulic cylinders to control the vertical lifting and lowering of multiple extrusion dies. This not only increases the equipment manufacturing cost, but also, because the lifting and lowering speed controlled by each cylinder or hydraulic cylinder has a certain error, the force applied by each extrusion die to the corresponding aluminum billet will not be completely the same, resulting in certain deviations in the wall thickness and dimensions of the produced aluminum profiles, thus reducing the product quality.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a multi-cavity die head linkage aluminum profile extrusion forming device, including a machine base 1. An extrusion forming die base 2 and an L-shaped beam frame 3 are fixedly installed on the top of the machine base 1. The top of the extrusion forming die base 2 has multiple aluminum profile forming cavities 4 arranged at equal intervals. Multiple vertical beams 5 are arranged above the extrusion forming die base 2. Pressure sensors 6 are fixedly installed at the bottom of each of the multiple vertical beams 5. Extrusion dies 7 are fixedly installed at the bottom of each of the multiple pressure sensors 6. The multiple extrusion dies 7 are respectively located directly above the corresponding aluminum profile forming cavities 4. A driving mechanism is arranged between the L-shaped beam frame 3 and the vertical beams 5. The driving mechanism includes multiple racks 8. Multiple drive shafts 9, multiple gears 10, and a transmission assembly are provided. Multiple racks 8 are fixedly installed on the right side wall of the corresponding vertical beam 5. The multiple drive shafts 9 rotate through the rear side wall of the L-shaped beam frame 3. The multiple gears 10 are fixedly sleeved on the front end of the corresponding drive shafts 9 and mesh with the corresponding racks 8. The transmission assembly is located on the rear side of the L-shaped beam frame 3 and is used to control the synchronous rotation of the multiple drive shafts 9. The transmission assembly includes multiple gears 2 11, multiple drive shafts 12, multiple gears 3 13, a motor 14, and a gear 4 15. The multiple gears 2 11 are fixedly sleeved on the corresponding drive shafts. At the rear end of the L-shaped beam 3, multiple drive shafts 12 are rotatably mounted on the rear outer wall. The drive shafts 12 and drive shaft 9 are arranged alternately. Multiple gears 13 are fixedly sleeved on the corresponding drive shafts 12. Multiple gears 11 and multiple gears 13 mesh alternately. The motor 14 is located behind the L-shaped beam 3. Gear 15 is fixedly mounted on the output shaft end of the motor 14. Gear 15 meshes with one of the gears 11. The motor 14 is a reversible motor. The motor 14 controls the rotation of gear 15, utilizing the meshing transmission action between gear 15 and one of the gears 11, and cooperating with... Multiple gears 11 and 13 mesh alternately to drive multiple drive shafts 9 to rotate synchronously in the same direction. In addition, multiple gears 10 mesh with their corresponding racks 8 to control the synchronous rise or fall of multiple vertical beams 5, thereby achieving the synchronous rise or fall of multiple extrusion dies 7. This allows for the simultaneous extrusion forming of multiple aluminum alloy profiles and ensures that the extrusion forming force is the same, improving work efficiency and production quality, and saving equipment costs. The pressure sensor 6 is designed to monitor the pressure value during the extrusion forming of aluminum alloy profiles, making it convenient for operators to grasp the pressure status of each cavity.

[0026] In this embodiment, a bearing seat 16 is fixedly installed on the rear outer wall of the L-shaped beam frame 3, and the motor 14 is fixedly installed on the bearing seat 16. The bearing seat 16 is designed to stably support the motor 14.

[0027] In this embodiment, gears 2 (11) and 3 (13) are set to have the same diameter to ensure that the transmission ratio is consistent and that the rotational speed of multiple drive shafts 9 is the same.

[0028] In this embodiment, the top of the L-shaped beam frame 3 is fixedly fitted with multiple guide sleeves 17 arranged at equal intervals, and the top of each of the multiple vertical beams 5 is fixedly installed with a vertical guide post 18. The top of each of the multiple vertical guide posts 18 slides through the corresponding guide sleeve 17. By utilizing the sliding connection between the vertical guide post 18 and the guide sleeve 17, precise guidance can be provided for the lifting and lowering of the vertical beam 5, avoiding deviation.

[0029] In this embodiment, limit grooves 19 are provided on the left side walls of multiple vertical beams 5. Multiple L-shaped limit rods 20 arranged at equal intervals are fixedly installed on the L-shaped beam frame 3. The ends of the multiple L-shaped limit rods 20 away from the L-shaped beam frame 3 are slidably installed in the corresponding limit grooves 19. By utilizing the sliding cooperation between the L-shaped limit rods 20 and the limit grooves 19, the lateral sway of the vertical beams 5 is further restricted, ensuring that the extrusion die head 7 can be accurately aligned with the aluminum profile forming cavity 4, reducing die wear and extending the service life of the equipment.

[0030] In this embodiment, a controller 21 is fixedly installed on the front side of the machine 1. Multiple pressure sensors 6 and motors 14 are electrically connected to the controller 21. The controller 21 is equipped with a display screen and multiple switch buttons. The pressure values ​​monitored by the multiple pressure sensors 6 can be displayed on the display screen for easy viewing by the operator. The multiple switch buttons can be used to control the multiple pressure sensors 6 and motors 14 to turn on or off respectively. The wiring connection method and control method are mature technologies in the field and have been fully disclosed and explained, so they will not be described again in this document.

[0031] In this embodiment, the top of the machine base 1 is provided with a storage groove 22 located in front of the extrusion molding die base 2. An electric telescopic rod 23 is fixedly installed on the bottom inner wall of the storage groove 22. The electric telescopic rod 23 is electrically connected to the controller 21. The extension and retraction of the electric telescopic rod 23 can be controlled by the switch button on the controller 21. An assembly plate 24 is fixedly installed at the output shaft end of the electric telescopic rod 23. An explosion-proof baffle 25 is fixedly installed on the top of the assembly plate 24. The width of the explosion-proof baffle 25 is larger than the width of the extrusion molding die base 2. The electric telescopic rod 23 is used to control the vertical lifting and lowering of the explosion-proof baffle 25. The explosion-proof baffle 25 is made of transparent tempered glass. The explosion-proof baffle 25 made of transparent tempered glass does not affect the operator's observation of the aluminum profile extrusion molding process, and can provide effective protection in case of emergencies (such as aluminum splashing or accidental mold detachment), thus protecting the safety of the operator.

[0032] With the above structure, when using the multi-cavity die head linkage aluminum profile extrusion molding device provided in this application, the operator places multiple aluminum blanks to be processed into multiple aluminum profile forming cavities 4 in sequence, and ensures that the aluminum blanks are placed in the correct positions. After the blanks are placed, the electric telescopic rod 23 is first controlled to extend. The output shaft end of the electric telescopic rod 23 pushes the assembly plate 24 and the explosion-proof baffle 25 to rise vertically. The explosion-proof baffle 25 gradually rises from the receiving groove 22, which can form a safety protection in front of the extrusion molding die base 2. In the subsequent extrusion molding process, it can provide effective protection in case of emergencies (such as aluminum splashing or accidental mold detachment), protect the safety of the operator, and improve the safety performance of the operation.

[0033] After the explosion-proof baffle 25 is raised, the motor 14 is turned on. The output shaft of the motor 14 drives the gear 4 15 to rotate. Since the gear 4 15 meshes with one of the gears 2 11, and multiple gears 2 11 mesh with multiple gears 3 13 in turn, multiple drive shafts 9 can be controlled to rotate synchronously in the same direction. Multiple gears 1 10 follow the corresponding drive shaft 9 to rotate synchronously. Since multiple gears 1 10 mesh with the corresponding racks 8, the rotation of gears 1 10 is converted into the vertical movement of racks 8, which can drive multiple vertical beams 5 to descend synchronously. During the descent of multiple vertical beams 5, multiple extrusion dies 7 follow the descent and gradually enter the corresponding aluminum profile forming cavity 4, so that multiple aluminum billets can be extruded and formed at the same time, improving work efficiency.

[0034] When the extrusion die 7 contacts and extrudes the aluminum billet, the pressure sensor 6 can monitor the extrusion pressure of each aluminum profile forming cavity 4 in real time and transmit the data to the controller 21, which is displayed on the screen in real time. By observing the pressure data, the operator can determine whether the extrusion status of each aluminum profile forming cavity 4 is normal, thereby ensuring that the aluminum billet is synchronously formed into a preset shape in multiple aluminum profile forming cavities 4.

[0035] After the aluminum profile is extruded, the motor 14 is reversed. The meshing transmission of gear 4 15 with one of the gears 2 11, along with the alternating meshing transmission of multiple gears 2 11 and multiple gears 3 13, and the meshing transmission of multiple gears 10 with their corresponding racks 8, can control multiple vertical beams 5 and multiple extrusion dies 7 to rise and reset synchronously. The multiple extrusion dies 7 disengage from the corresponding aluminum profile forming cavity 4. Then, the electric telescopic rod 23 is controlled to retract and reset, driving the explosion-proof baffle 25 to descend into the storage slot 22. The operator can then take out the multiple extruded aluminum profiles. Following the above operating steps, the aluminum profile extrusion processing can continue.

[0036] The foregoing has provided a detailed description of a multi-cavity die-linked aluminum profile extrusion forming device. Specific embodiments have been used to illustrate the principles and implementation methods of this application. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this application.
