Description

Technical Field

[0001] This utility model relates to the field of spinning die technology, and in particular to the structure of spinning die for aluminum alloy products. Background Technology

[0002] Aluminum alloy products are made by adding other alloying elements to aluminum. They possess characteristics such as light weight, high strength, good corrosion resistance, and excellent thermal conductivity. They are widely used in daily life and numerous industrial fields, such as aerospace and automotive manufacturing. Aluminum alloy products are diverse, including aluminum alloy doors and windows, and aluminum alloy parts for automobile engines. Spinning technology plays a crucial role in aluminum alloy product manufacturing. This is a precision machining process where an aluminum alloy blank is fixed on a spinning machine, and pressure is applied to it through spinning wheels, causing the aluminum alloy material to gradually deform and ultimately obtain the desired shape and size.

[0003] Spinning is a process that uses a combination of rotating dies and pressure to shape metal materials into parts of various shapes and sizes. During spinning, the rotating die applies pressure to the metal material, causing plastic deformation, while friction between the die and the metal also plays a role. This processing method allows for continuous processing of metal materials, resulting in high production efficiency and producing high-quality surfaces and precise shapes.

[0004] In existing technologies, some spinning die structures often lack effective designs specifically for the quick replacement of spun parts. The connection methods between their components are relatively complex and fixed. When it is necessary to change spun parts according to the requirements of different aluminum alloy products, operators need to spend a lot of time and effort to disassemble and install the relevant parts. This not only increases labor costs but also leads to a significant reduction in production efficiency. Therefore, this paper proposes a new aluminum alloy product spinning die structure to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spinning die structure for aluminum alloy products includes a base, a control box slidably connected to the top of the base, a hydraulic cylinder fixedly connected to the front inner wall of the control box, a disassembly and assembly mechanism fixedly connected to the drive end of the hydraulic cylinder, and a cooling mechanism fixedly connected to the rear top of the base.

[0008] The disassembly and assembly mechanism includes a sliding block, the front end of which is fixedly connected to the drive end of the hydraulic cylinder. A cylinder is fixedly connected to the inner front wall of the sliding block. A connecting frame is fixedly connected to the drive end of the cylinder. Rotating plates are rotatably connected to both the upper and lower sides of the connecting frame. Transmission plates are rotatably connected to the opposite sides of the two rotating plates. Rotating blocks are rotatably connected to the opposite sides of the two transmission plates. Pressure plates are fixedly connected to the opposite sides of the two rotating blocks. Spinning assemblies are detachably connected to the outside of the two pressure plates.

A filter plate is fixedly connected to the inside of the square box. An air outlet pipe is fixedly connected to the left side of the square box. A connecting pipe is fixedly connected to the output end of the air outlet pipe, and a fan is fixedly connected to the bottom end of the connecting pipe.

[0011] As a further description of the above technical solution:

[0012] The spinning assembly includes a mounting block with a mounting through hole inside. The opposite sides of the two pressure plates are in contact with the upper and lower inner walls of the mounting through hole. A spinning wheel is provided inside the mounting block.

[0018] The upper and lower sides of the interior of the chamber are fixedly connected to fixed rods, and the inner wall of the transmission plate is rotatably connected to the outer wall of the fixed rods.

[0019] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when changing different types of spinning parts, the cylinder is activated to generate power, driving the connecting frame to move rearward. The movement of the connecting frame causes the rotating plates connected to the upper and lower sides to rotate around their upper and lower sides. The rotation of the rotating plates, in turn, causes the transmission plate to rotate around the fixed rod. The fixed rod provides a fulcrum for the rotation of the transmission plate, ensuring the accuracy of the rotation. The rotation of the transmission plate is transmitted to the pressure plate through the rotating block, causing the pressure plate to rotate outwards and downwards. The pressure plate contacts the inner walls of the upper and lower sides of the mounting through hole, thereby fixing or loosening the mounting block (the mounting carrier of the spinning wheel). This design allows the spinning wheel to be quickly installed, fixed, or disassembled, and allows for convenient replacement of suitable spinning parts according to different requirements of aluminum alloy products.

[0025] 2. In this utility model, during the processing of the aluminum alloy workpiece by the tail-top device and the mold fixing device, the exhaust fan draws the dust, impurities, and air generated during processing into a square box. A filter plate filters the dust and impurities, a cooling pipe cools the air, and finally, a fan blows the cooled, clean air onto the workpiece. This maintains a clean processing environment, preventing dust and impurities from affecting processing accuracy or damaging the workpiece, while also cooling the workpiece to ensure it is processed within a suitable temperature range, thus improving the processing quality.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of an aluminum alloy product spinning die structure, including a base 1, which is the foundation of the entire aluminum alloy product spinning die structure. It provides a stable support platform for other components, ensuring the stability of the entire structure during operation. It is the basis for the installation and coordinated operation of various components and bears the various forces generated during the operation of the entire device. A control box 2 is slidably connected to the top of the base 1, and a hydraulic cylinder 3 is fixedly connected to the front inner wall of the control box 2. The control box 2 plays a role in controlling and protecting the internal components and facilitating the adjustment of the position of the spinning parts. A disassembly and assembly mechanism is fixedly connected to the drive end of the hydraulic cylinder 3, and a cooling mechanism is fixedly connected to the rear top of the base 1.

[0034] The disassembly and assembly mechanism includes a sliding block 4. The front end of the sliding block 4 is fixedly connected to the drive end of the hydraulic cylinder 3, and the outer side of the sliding block 4 is slidably connected to the inner wall of the control box 2. The hydraulic cylinder 3 serves as the drive source, with its drive end connected to the sliding block. Its back-and-forth movement controls the back-and-forth movement of the spun part. A cylinder 5 is fixedly connected to the inner wall of the front side of the sliding block 4. A connecting frame 6 is fixedly connected to the drive end of the cylinder 5. When the spun part needs to be replaced, the cylinder 5 is activated to generate power, driving the connecting frame 6 to move rearward. Rotating plates 7 are rotatably connected to both the upper and lower sides of the connecting frame 6, and the rotating plates 7 rotate around their upper and lower sides as the connecting frame 6 moves. Transmission plates 8 are rotatably connected to the opposite sides of the two rotating plates 7, and rotating blocks 9 are rotatably connected to the opposite sides of the two transmission plates 8. Pressure plates 10 are fixedly connected to the opposite sides of the two rotating blocks 9. A chamber 11 is formed inside the sliding block 4, and the outer wall of the connecting frame 6 is slidably connected to the inner wall of the chamber 11. The chamber 11 provides sliding space for the outer wall of the connecting frame 6. Fixed rods 12 are fixedly connected to both the upper and lower sides of the interior of chamber 11, and the inner wall of transmission plate 8 is rotatably connected to the outer wall of fixed rods 12. Fixed rods 12 provide a fulcrum for the rotation of transmission plate 8, ensuring that transmission plate 8 can rotate accurately according to design requirements, and are the key support structure for the rotation of transmission plate 8. When rotating plate 7 rotates, transmission plate 8 rotates around fixed rods 12, and drives pressure plate 10 to rotate upward and outward through rotating block 9. It is the intermediate transmission component that converts the rotation of rotating plate 7 into the rotation of pressure plate 10, and plays a key connecting role in realizing the installation and fixation of the spun parts. Rotating block 9 connects transmission plate 8 and pressure plate 10, and transmits the rotation of transmission plate 8 to pressure plate 10, enabling pressure plate 10 to rotate accurately upward and outward.

[0035] Two pressure plates 10 are detachably connected to a spinning assembly. The spinning assembly includes a mounting block 13, which has a mounting through hole 14 inside. The opposite sides of the two pressure plates 10 contact the upper and lower inner walls of the mounting through hole 14. A spinning wheel 15 is installed inside the mounting block 13. The mounting block 13 is an important part of the spinning assembly. It has a mounting through hole 14 inside and serves as the mounting carrier for the spinning wheel 15. The pressure plates 10 press against the mounting through hole 14 to fix it to the entire structure, providing a stable mounting position for the spinning wheel 15. The spinning wheel 15 is the component that directly spins aluminum alloy products.

[0036] A tail-top device 16 is fixedly connected to the top left of the base 1, and a mold fixing device 17 is fixedly connected to the top right of the base 1. The mold fixing device 17 is mainly used to fix the mold and maintain its stability during processing. When processing aluminum alloy workpieces, the tail-top device 16 and the mold fixing device 17 cooperate to position and support the aluminum alloy workpieces, ensuring the accuracy of the workpiece's position during processing. It is an important component for ensuring processing precision.

[0037] Reference Figure 1 , Figure 2 and Figure 4 The cooling mechanism includes a support frame 18, the bottom of which is fixedly connected to the rear top of the base 1. An air inlet pipe 19 is fixedly connected to the right side of the inside of the support frame 18, and an exhaust fan 20 is fixedly connected to the left side of the air inlet pipe 19. The bottom of the exhaust fan 20 is fixedly connected to the top of the support frame 18, and an air inlet hood 21 is fixedly connected to the output end of the air inlet pipe 19. The air inlet pipe 19, air inlet hood 21, and exhaust fan 20 work together to transport dust, impurities, and air generated during processing to the channel of the square box 22, ensuring that air and impurities can smoothly enter the cooling mechanism for processing. The square box 22 is fixedly connected to the left side of the exhaust fan 20, and the bottom of the square box 22 is fixedly connected to the top of the support frame 18. The bottom of the support frame 18 is fixed to the rear top of the base 1, providing support for the components of the cooling mechanism, including the air inlet pipe 19, exhaust fan 20, and square box 22. A dust collection plate 27 is slidably connected to the right side of the inside of the square box 22, and a cooling pipe 28 is detachably connected to the left side of the inside of the square box 22. A filter plate 23 is fixedly connected inside the square box 22. The square box 22 is the core processing part of the cooling mechanism. A dust collection plate 27 is slidably connected to its right side to collect dust and impurities; a cooling pipe 28 is detachably connected to its left side for cooling air; and the filter plate 23 is fixedly connected inside to filter the air. The square box 22 is the place for air purification and cooling. An air outlet pipe 24 is fixedly connected to the left side of the square box 22. A connecting pipe 25 is fixedly connected to the output end of the air outlet pipe 24. The external part of the connecting pipe 25 is fixedly connected to the top of the support frame 18. A fan 26 is fixedly connected to the bottom end of the connecting pipe 25. The connecting pipe 25 transmits the air output from the air outlet pipe 24 to the fan 26. The function of the fan 26 is to blow the cooled and purified air onto the workpiece during processing to cool the workpiece and ensure that the workpiece temperature is within a suitable range during processing.

[0038] Working principle: When it is necessary to replace different types of spinning parts, first align the mounting block 13 with the sliding block 4, and then generate power by opening the cylinder 5 to drive the connecting frame 6 to move backward. The backward movement of the connecting frame 6 drives the two rotating plates 7 to rotate around its upper and lower sides. The rotation of the rotating plate 7 drives the transmission plate 8 and the side connected to the rotating plate 7 to rotate around the fixed rod 12. Through the rotation of the transmission plate 8 and the connection of the rotating block 9, the two pressure plates 10 are driven to rotate upward and outward, thereby pressing the mounting through hole 14 and fixing the mounting block 13. This completes the quick installation and fixing of the spinning wheel 15. The appropriate spinning parts can be replaced according to the different requirements of aluminum alloy products.

[0039] When the tail-top device 16 and the mold fixing device 17 process the aluminum alloy workpiece, the exhaust fan 20 generates power to drive the dust, impurities and air generated during processing through the air intake hood 21 and air intake pipe 19 into the square box 22. The filter plate 23 filters the dust and impurities in the air. The filtered air is cooled by the cooling pipe 28, and then blows the cooled clean air onto the workpiece during processing through the air outlet pipe 24 and connecting pipe 25 and the fan 26 to cool it down.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
