Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, specifically to a high-strength, lightweight server aluminum alloy bracket processing device and method. Background Technology

[0002] High-strength lightweight server aluminum alloy brackets are support structures designed specifically for server equipment, using high-performance aluminum alloy as the core material. Through optimization of the aluminum alloy composition, precise control of the forming process, and mechanical simulation and rational design of the bracket structure, they significantly reduce their own weight, achieving lightweight assembly and maintenance, while possessing excellent structural strength, rigidity, deformation resistance, and vibration resistance. They can effectively support the weight of the server body and related accessories, providing reliable support for the stable installation and space layout optimization of the server in the rack. They can also rely on the good thermal conductivity of aluminum alloy to assist in server heat dissipation, adapting to the core usage requirements of data centers and other scenarios for lightweight, high load-bearing, and high stability support structures for server equipment.

[0003] The high-strength lightweight server aluminum alloy bracket processing device is a specialized forming and processing equipment developed and designed specifically for the structural characteristics and processing precision requirements of high-strength lightweight server aluminum alloy brackets, with cutting processing as the core technology. This equipment uses cutting processing as the core operation mode, is adapted to the cutting processing properties of aluminum alloy materials, and is specifically designed to serve the integrated forming and processing process of high-strength lightweight server aluminum alloy brackets. It is a specialized processing equipment for achieving precise processing and forming of this type of aluminum alloy bracket.

[0004] Server aluminum alloy brackets often adopt a thin-walled structure design. This type of structure has relatively weak rigidity and is easily subjected to external forces such as cutting forces during processing, which can cause workpiece vibration. This vibration will be transmitted along the bracket body, not only spreading to non-processed areas and causing overall chatter, but also being transmitted to the clamping and cutting components of the processing device, affecting the stability and positioning accuracy of the cutting tool. This can lead to defects such as tool marks and burrs on the processed surface of the bracket, reducing the pass rate of dimensional tolerances and geometric accuracy. Therefore, a high-strength and lightweight server aluminum alloy bracket processing device and method are proposed to address the above problems. Summary of the Invention

A first spring is fixedly connected to the inner side of the air chamber, and a fixing post is fixedly connected to the other end of the first spring. A second rubber sealing ring is fixedly connected to the outer side of the fixing post.

[0008] As a further optimization of the present invention, the upper end of the base plate is fixedly connected to a bracket, and the outer side of the bracket is fixedly connected to a folded plate included in a plurality of support and drive components.

[0009] As a further optimization of the present invention, a cutting groove is provided between the folded plates, and a gap is provided between the two positioning components.

[0010] As a further optimization of the present invention, one side of the folded plate is fixedly connected to the cylinder body of the electric hydraulic cylinder, and a pressure plate is fixedly connected to the end of the piston rod of the electric hydraulic cylinder, with an inclined surface at one end of the pressure plate.

[0011] As a further optimization of the present invention, the folded plate has a sliding hole on its inner side, and a sliding column of the positioning component is slidably connected to the inner side of the sliding hole. A first baffle is fixedly connected to one end of the sliding column, and a second spring is fixedly connected to one end of the first baffle.

[0014] As a further optimization of the present invention, the inner side of the wheel housing is provided with a shaft rotation hole, the shaft rotation hole is rotatably connected to a rotating column through a bearing, a pressure roller is fixedly connected to one side of the rotating column, and the pressure roller presses on the frame blank.

[0015] As a further optimization of the present invention, the end of the cylinder shell away from the first rubber sealing ring is provided with a through hole, the air chamber and the inner side of the air guide pipe are both filled with air, the outer side of the second rubber sealing ring is in contact with the inner side of the air chamber, and the inner side of the first rubber sealing ring is in contact with the outer side of the fixing column.

[0016] A method for processing a high-strength, lightweight server aluminum alloy bracket;

[0017] Step 1: When assembling the frame blank, install it between two rolling components. During insertion, the frame blank presses against the arc-shaped surface of the pressure roller, driving the wheel housing and fixed column to move into the air chamber. The electric valve is pre-opened. When the fixed column moves, it is sealed by the second rubber sealing ring and the first rubber sealing ring. Air in the electric valve flows into the air chamber through the air guide pipe. The fixed column compresses the first spring, and the air in the air chamber near the first spring is discharged through the through hole of the cylinder shell. Start the electric hydraulic cylinder to drive the pressure plate to move. The inclined surface presses the pressure block to move it towards the frame blank. The upper and lower electric hydraulic cylinders move the same distance. The frame blank is fixed by clamping it with the upper and lower pressure blocks.

[0018] Step 2: When cutting the frame blank, the CNC vertical lifting cutting machine controls the cutting blade to move down from the cutting groove. The distance between the two pressure plates does not hinder the cutting. The frame blank is cut into sections. The cutting impact causes the frame blank to vibrate. The vibration is transmitted to the fixed column through the pressure roller and wheel shell, causing it to move slightly. The air in the air chamber reduces the vibration, and the first spring provides elastic buffering. The gas in the rubber ball flows back and forth into the air chamber through the air guide pipe. The size of the electric valve is adjusted to control the gas flow and adjust the damping intensity to adapt to the vibration changes.

[0019] Step 3: When adjusting the blank cutting position, the integrated controller closes the electric valve and controls the electric hydraulic cylinder to drive the pressure plate to reset; the elastic thrust of the second spring drives the first baffle, sliding column, second baffle, and pressure block to move. The second baffle controls the moving distance of the sliding column, the pressure block moves away from the blank, the pressure roller remains in contact, the protective component limits the rolling component, and when the blank is pushed, the pressure roller rotates with the friction force, and the rotating column rotates synchronously in the shaft rotation hole through the bearing to complete the position adjustment.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the device can fix the workpiece blank at four points by means of the electric hydraulic cylinder, pressure plate and pressure block, which provides a stable foundation for its cutting and processing. At the same time, it is easy to quickly release the fixation at any time and can flexibly change the processing part of the workpiece blank, thereby improving the convenience and efficiency of the processing operation.

[0022] 2. In this invention, the device can flexibly and precisely control the vibration reduction intensity through the electric valve, fixed column and pressure roller, adapt to the vibration changes of different cutting stages of the workpiece blank, effectively improve the dimensional accuracy, form and position accuracy and surface quality of thin-walled workpiece cutting, and at the same time reduce the impact and wear of vibration on various components of the equipment, and extend the service life of the equipment.

[0023] 3. In this invention, by using the pressure block, pressure roller and rolling assembly, the device can effectively prevent the workpiece from shifting left or right when adjusting the cutting position of the workpiece blank, ensuring processing accuracy, while reducing the labor intensity during the workpiece position adjustment process and improving the ease of operation.

[0038] 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.

[0039] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0040] Please see Figures 1-9 The present invention provides a technical solution:

[0041] A high-strength, lightweight server aluminum alloy bracket processing device and method includes a base plate 1, a bracket 2, and a bracket blank 3. A support drive assembly 4 is installed on the outside of the bracket 2, a protective assembly 5 is installed on the inside of the support drive assembly 4, a positioning assembly 6 is installed on one side of the support drive assembly 4, and a rolling assembly 7 is installed at one end of the protective assembly 5. The protective assembly 5 includes a cylindrical shell 51, an air chamber 52 is opened on the inside of the cylindrical shell 51, a first rubber sealing ring 53 is fixedly connected to the inside of the cylindrical shell 51, an air guide pipe 54 is fixedly connected to the outside of the cylindrical shell 51, an electric valve 55 is fixedly connected to one side of the air guide pipe 54, a rubber ball 56 is fixedly connected to the valve port of the electric valve 55, a first spring 57 is fixedly connected to the inside of the air chamber 52, a fixing post 58 is fixedly connected to the other end of the first spring 57, and a second rubber sealing ring 59 is fixedly connected to the outside of the fixing post 58.

[0042] As a further implementation of this solution, a bracket 2 is fixedly connected to the upper end of the base plate 1. The outer side of the bracket 2 is fixedly connected to the folded plate 41 included in the multiple support drive components 4. Through the above setting, this connection method can enhance the installation stability of the folded plate 41, ensure that the subsequent electric hydraulic cylinder 42, pressure plate 43 and other components do not shift during operation, and provide reliable structural support for the precise fixing and cutting of the workpiece blank 3.

[0043] As a further implementation of this solution, a cutting groove 46 is left between the folding plates 41, and a gap is set between the two positioning components 6. Through the above settings, the reserved cutting groove 46 can avoid interference between the cutting blade and the folding plate 41 when the cutting blade moves down, and the gap between the two positioning components 6 can ensure the activity space of components such as the sliding column 61 and the pressure block 65, ensuring that the cutting operation and workpiece fixing and adjustment operations are carried out smoothly, and improving the continuity of processing.

[0044] As a further implementation of this solution, one side of the folded plate 41 is fixedly connected to the cylinder body of the electric hydraulic cylinder 42, and the piston rod end of the electric hydraulic cylinder 42 is fixedly connected to the pressure plate 43. One end of the pressure plate 43 is provided with an inclined surface 44. Through the above-mentioned arrangement, this connection structure can ensure that the electric hydraulic cylinder 42 drives the pressure plate 43 to move smoothly, and the inclined surface 44 can accurately squeeze the pressure block 65, ensuring that the clamping force of the pressure block 65 on the blank 3 is uniform, realizing the stable fixation of the blank 3, and avoiding the workpiece from loosening during processing.

[0045] As a further implementation of this solution, a sliding hole 45 is provided on the inner side of the folded plate 41. A sliding column 61, including the positioning component 6, is slidably connected to the inner side of the sliding hole 45. A first baffle 63 is fixedly connected to one end of the sliding column 61, and a second spring 62 is fixedly connected to one end of the first baffle 63. The end of the second spring 62 away from the first baffle 63 is fixedly connected to the folded plate 41. Through the above arrangement, the sliding hole 45 provides a stable sliding trajectory for the sliding column 61. The elastic action of the second spring 62 can drive the sliding column 61 and the pressure block 65 to quickly reset, which facilitates the quick release of the fixation of the blank 3 and improves the efficiency of workpiece adjustment and replacement.

[0046] As a further implementation of this solution, a second baffle 64 is fixedly connected to the outside of the sliding column 61, and a pressure block 65 is fixedly connected to one end of the sliding column 61. The pressure block 65 is pressed and fixed on the blank 3. Through the above settings, the second baffle 64 can accurately limit the movement distance of the sliding column 61, and avoid the pressure block 65 from excessively squeezing the blank 3 and causing damage to the workpiece. At the same time, the pressing and fixing effect of the pressure block 65 can help to achieve four-point fixation of the blank 3, and enhance the stability of the workpiece during processing.

[0047] As a further implementation of this solution, the rolling assembly 7 includes a wheel housing 71, one end of which is fixedly connected to the fixed column 58. A gap is provided between the wheel housing 71 and the pressure plate 43. Through the above arrangement, this structure can ensure that the wheel housing 71 drives the fixed column 58 to smoothly transmit the cutting vibration of the blank 3. At the same time, the gap between the wheel housing 71 and the pressure plate 43 can avoid interference between the two during operation, ensuring that the vibration damping mechanism and the fixing mechanism work smoothly and improving the vibration damping effect.

[0048] As a further implementation of this solution, a shaft rotation hole 72 is provided on the inner side of the wheel housing 71. The shaft rotation hole 72 is rotatably connected to a rotating column 73 through a bearing. A pressure roller 74 is fixedly connected to one side of the rotating column 73. The pressure roller 74 presses on the blank holder 3. With the above arrangement, the rotating column 73 can rotate flexibly in the shaft rotation hole 72 through the bearing, which can drive the pressure roller 74 to rotate synchronously with the adjustment of the blank holder 3, reduce the friction between the pressure roller 74 and the blank holder 3 during adjustment, reduce the labor intensity of adjustment, and at the same time, the pressing effect of the pressure roller 74 can help fix the blank holder 3, prevent the workpiece from shifting during adjustment, and ensure processing accuracy.

[0049] As a further implementation of this solution, a through hole is provided at the end of the cylinder shell 51 away from the first rubber sealing ring 53. The air chamber 52 and the air guide pipe 54 are both filled with air. The outer side of the second rubber sealing ring 59 is in contact with the inner side of the air chamber 52, and the inner side of the first rubber sealing ring 53 is in contact with the outer side of the fixed column 58. Through the above arrangement, the smooth discharge and inflow of air inside the air chamber 52 can be realized. The sealing effect of the second rubber sealing ring 59 and the first rubber sealing ring 53 can ensure the airflow is sealed, ensuring that the air inside the air chamber 52 and related components can effectively achieve vibration reduction and buffering, accurately control the vibration reduction intensity, and reduce workpiece processing defects.

[0050] Workflow: During the assembly of the frame blank 3, the frame blank 3 is placed between the two rolling components 7. During the insertion process, the frame blank 3 will squeeze the pressure roller 74. Since the frame blank 3 is located on the arc surface of the pressure roller 74, the pressure roller 74 is driven by the action of the frame blank 3 squeezing the pressure roller 74, causing the wheel housing 71 to move. The wheel housing 71 drives the fixed column 58 to move, and the fixed column 58 moves into the air chamber 52. Before this, the electric valve 55 is in the open state. When the fixed column 58 moves, the second rubber sealing ring 59 seals the fixed column 58 and the cylinder housing 51, and the first rubber sealing ring 53 seals the cylinder housing 51 and the fixed column 58. This allows the air inside the electric valve 55 to flow into the air chamber 52 through the air guide pipe 54. At the same time, the first spring 57 is... When the fixed column 58 is compressed, the air inside the air chamber 52 will be discharged through the through hole of the cylinder shell 51. When the electric hydraulic cylinder 42 is activated, it drives the pressure plate 43 to move. When the inclined surface 44 contacts the top of the upper pressure block 65, the pressure block 65 is squeezed by the inclined surface 44, causing the pressure block 65 to move towards the frame blank 3. The upper electric hydraulic cylinder 42 and the lower electric hydraulic cylinder 42 move the same distance. The upper pressure block 65 and the lower pressure block 65 achieve the function of clamping the frame blank 3, thereby fixing the frame blank 3. This installation of the frame blank 3 can fix the frame blank 3 in four positions, providing a stable foundation for the cutting of the frame blank 3. At the same time, it can be conveniently and quickly released from the fixed state of the frame blank 3 at any time, providing convenience for quick replacement of different parts of the frame blank 3.

[0051] When cutting the blank 3, the existing CNC vertical lifting aluminum alloy profile cutting machine controls the cutting blade to move up and down. The blade moves downwards from the cutting groove 46. A gap is provided between the two pressure plates 43 to avoid obstructing the movement of the cutting blade, allowing the CNC vertical lifting aluminum alloy profile cutting machine to cut the blank 3 into segments. During this process, the blank 3 is impacted by the cutting blade, and its vibration is transmitted to both ends. Because the pressure roller 74 fixes the blank 3, the vibration is transmitted to the fixed column 58 through the pressure roller 74 and the wheel housing 71. The fixed column 58 undergoes a slight displacement. Air is provided inside the air chamber 52 to dampen the movement of the fixed column 58. Simultaneously, under the elastic thrust of the first spring 57... This provides a buffering effect for the fixed column 58. During this process, the gas inside the rubber ball 56 enters the air chamber 52 through the air guide pipe 54. The amount of gas flowing through the air guide pipe 54 is controlled by the opening size of the electric valve 55, thereby controlling the intensity of vibration damping for the fixed column 58. It can adapt to the vibration changes of the blank 3 under different cutting stages and different impact forces, achieving flexible and precise control of the vibration damping intensity. It always ensures that the vibration damping effect matches the cutting vibration, which not only greatly improves the dimensional accuracy, shape and position accuracy and surface quality of the thin-walled structure cutting of the blank 3, but also reduces the impact and wear of vibration on the fixed column 58, wheel housing 71, pressure roller 74 fixed clamping parts and cutting equipment through controllable buffering and vibration damping, thus extending the service life of each component of the equipment.

[0052] When adjusting the cutting position of the blank holder 3, the integrated controller controls the electric valve 55 to close and controls the electric hydraulic cylinder 42 to reset the pressure plate 43. Under the elastic thrust of the second spring 62, the first baffle 63 drives the sliding column 61, the second baffle 64 and the pressure block 65 to move. The second baffle 64 controls the moving distance of the sliding column 61. At this time, the pressure block 65 moves away from the blank holder 3, while the pressure roller 74 remains in contact with the blank holder 3. At the same time, the protective component 5 limits the position of the rolling component 7 to prevent the blank holder 3 from shifting left or right. When pushing the blank holder 3, the pressure roller 74 will rotate due to the friction with the blank holder 3. The rotating column 73 rotates inside the shaft rotating hole 72 through the bearing. This adjustment of the position of the blank holder 3 can ensure that the blank holder 3 will not shift, ensure the machining accuracy of the blank holder 3, and reduce the labor intensity when adjusting the blank holder 3.
