Description

Technical Field

[0001] This utility model relates to the technical field of anti-sway plates for storage tanks, and more specifically, to a molding device for aerospace anti-sway plate parts. Background Technology

[0002] As an important anti-sway device, the anti-sway plate of the launch vehicle propellant tank is installed in the fuel tank of the launch vehicle by screwing it to the inner corner plate of the tank. It controls the swaying of the propellant in the tank and ensures the stability of the rocket's attitude during flight and the normal operation of the engine.

[0003] Anti-sway plates are generally made of annealed (M-state) hard aluminum alloys such as LY12, which are then heat-treated and quenched for strengthening after forming. Because these parts are generally thin-walled (1.2-2mm) and large in size, they are severely twisted and deformed after quenching. The thin-walled and large-size structural characteristics also make it difficult to straighten these parts, and the surface quality of the parts after a lot of hammering is poor.

[0004] Currently, the common forming method for anti-sway baffle parts is to form the part shape in the annealed state and then correct the shape after quenching. Due to the large demand for such parts in launch vehicle propellant tanks, taking a newly developed booster model as an example, the liquid oxygen tank alone requires more than 200 anti-sway baffle parts. The large amount of correction work affects the production efficiency and surface quality of the products.

[0005] In conclusion, how to effectively improve product production efficiency and surface quality is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

This application discloses an aerospace anti-sway plate component forming device.

[0029] The core of this utility model is to provide a molding device for aerospace anti-sway plate parts.

[0030] Please refer to Figures 1 to 3 ,in Figure 1 This is an axonometric schematic diagram of the overall structure of the aerospace anti-sway plate component molding device. Figure 2 This is a side view of the aerospace anti-sway plate component molding device. Figure 3 for Figure 2 Sectional view at point AA.

[0031] The aerospace anti-sway plate part forming device provided by this utility model includes an upper template 1 and a lower template 2 arranged opposite to each other. A pressing component 3 is provided on the upper template 1. The pressing component 3 is used to press the non-bending part of the part 8 to be processed between the upper template 1 and the lower template 2. A second forming block 5 is fixedly provided on the lower template 2. A first forming block 4 that cooperates with the second forming block 5 is fixedly provided on the upper template 1. The first forming block 4 and the second forming block 5 are used to bend the part 8 to be bent to a specified size.

[0032] The part 8 to be processed is placed on the lower template 2, and the pressure assembly 3 presses the part 8 between the upper template 1 and the lower template 2 to ensure the surface quality of the part 8 during the forming process. The first forming block 4 and the second forming block 5 are used to quickly bend the part 8 to meet production requirements, improving production efficiency. It should be noted that the first forming block 4 has a first forming surface on the side closest to the part 8, and the second forming block 5 has a second forming surface on the side of the part 8 that mates with the first forming surface. The angle and dimensions of the first and second forming surfaces are set according to actual production needs. The first and second forming surfaces clamp the part 8 between them to complete the forming process.

[0033] The aforementioned aerospace anti-sway plate component forming device uses a pressing component 3 to press the non-bending portion of component 8 between the upper template 1 and the lower template 2. The pressing component 3 can fix the non-bending portion of component 8 between the upper template 1 and the lower template 2, preventing deformation of the non-bending portion of component 8 during the forming process and effectively improving the surface quality of component 8. At the same time, with the help of the first forming block 4 and the second forming block 5, the part of component 8 to be bent is formed into the required shape by the mold closing of the first forming block 4 and the second forming block 5. The forming force of each part during the forming process is controllable, and the bending deformation is uniform, which can effectively improve the processing accuracy of component 8, reduce the processing cycle of component 8, reduce the labor intensity of the operator, improve the quality of component 8, and ensure product consistency. By changing different first forming blocks 4 and second forming blocks 5, forming operations of component 8 under different size requirements can be achieved.

[0034] The aerospace anti-sway plate part forming device provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0035] In one specific implementation, reference is made to... Figures 1 to 3 The pressing assembly 3 includes a pressing plate 31 disposed on the upper template 1, and the pressing plate 31 is horizontally arranged between the upper template 1 and the lower template 2.

[0036] By using the horizontally set pressure plate 31, the part 8 is pressed between the lower template 2 and the pressure plate 31. The lower template 2 and the pressure plate 31 clamp the non-bending part of the part 8, ensuring that the non-bending part of the part 8 remains stable during the forming process, thereby improving the surface flatness of the non-bending part of the part 8 during the forming process and improving the surface quality of the part 8.

[0037] Furthermore, an auxiliary component 6 is provided between the pressure plate 31 and the upper template 1. The auxiliary component 6 is used to assist the pressure plate 31 in pressing the part 8 onto the lower template 2, thereby improving the stability of the pressure plate 31 when pressing the part 8 onto the lower template 2. The auxiliary component 6 further enhances the pressing effect of the pressure plate 31 on the part 8. At the same time, it enhances the buffering performance of the pressure plate 31.

[0038] Optionally, the auxiliary component 6 includes a plurality of first pressure springs 61 connected between the upper template 1 and the pressure plate 31. A spring limiting bolt 62 is slidably inserted into the upper template 1, and the end of the spring limiting bolt 62 away from the upper template 1 is threadedly connected to the pressure plate. A plurality of first mounting holes 63 are provided on both sides of the spring limiting bolt 62 on the upper template 1, and a plurality of second mounting holes 64 are provided on the pressure plate 31 to cooperate with the first mounting holes 63. A second pressure spring 65 is provided between the corresponding first mounting holes 63 and second mounting holes 64.

[0039] As the hydraulic press moves the upper template 1 and pressure plate 31 downwards, the first pressure spring 61 and the second pressure spring 65 provide support for the pressure plate 31, ensuring its stability. After the pressure plate 31 contacts the part 8, the spring limit bolt 62 moves the pressure plate 31 toward the upper template 1. Together with the first pressure spring 61 and the second pressure spring 65, this movement provides cushioning and shock absorption, effectively reducing damage to the mold caused by excessive impact and extending its service life.

[0040] In some other embodiments, the first pressure spring 61 and the second pressure spring 65 may be hydraulic gas springs. A hydraulic gas spring is a new type of spring capable of automatically adjusting damping and elasticity as needed. It typically consists of two sealed air chambers connected to each other, with elasticity adjustment achieved through pressure changes within the chambers. Hydraulic gas springs are lightweight, have low maintenance costs, and are highly reliable. Using hydraulic gas springs in molds can provide more stable support and cushioning while reducing mold maintenance costs.

[0041] Based on any of the above embodiments, refer to Figure 3 The aerospace anti-sway plate part forming device provided by this utility model also includes a positioning component 7 disposed on the lower template 2, which is used to position the part 8 on the lower template 2.

[0042] Positioning component 7 positions the unfolded material of part 8 onto the lower template 2, ensuring the accuracy of part 8's position on the lower template 2. This is crucial for guaranteeing the machining precision of part 8. Simultaneously, precise positioning ensures that the part will not experience dimensional or shape deviations due to positional shifts during processing. Furthermore, in continuous production, positioning component 7 maintains the repeatability of part 8's positioning, ensuring that each batch of parts 8 has the same dimensions and shape, thereby improving the overall product quality.

[0043] Optionally, the positioning component 7 includes a positioning pin hole 71 formed on the lower template 2 and a positioning pin 72 that mates with and is inserted into the positioning pin hole 71, so that one end of the part 8 is positioned on the lower template 2. A clearance hole is provided on the pressure plate 31 to allow the end of the positioning pin 72 to pass through, ensuring stability during device operation. Multiple positioning pin holes 71 and positioning pins 72 can be provided to enhance the stability of the part 8 on the lower template 2.

[0044] The coordinated use of the locating pin hole 71 and the locating pin 72 ensures that one end of the part is accurately positioned on the lower template. This precise positioning is fundamental to subsequent machining and assembly processes and is crucial for ensuring the overall quality and accuracy of the product. Simultaneously, during mold closing and machining, the locating pin 72 prevents the part 8 from shifting due to external forces or vibrations, ensuring that the part 8 remains in its predetermined position.

[0045] In some other embodiments, the positioning component 7 may also be a structure in which a positioning block and a positioning groove cooperate, or in the form of a guide sleeve and a guide post cooperate, so as to realize the positioning of part 8 between the upper template 1 and the lower template 2.

[0046] Based on any of the above embodiments, refer to Figure 3 A first detachable structure 9 is provided between the first forming block 4 and the upper template 1, and the first detachable structure 9 is used to detachably mount the first forming block 4 onto the upper template 1. A second detachable structure 10 is provided between the second forming block 5 and the lower template 2, and the second detachable structure 10 is used to detachably mount the second forming block 5 onto the lower template 2.

[0047] By utilizing the first detachable structure 9 and the second detachable structure 10, the first molding block 4 and the second molding block 5 can be detached, facilitating the replacement of the first molding block 4 and the second molding block 5. Different first molding blocks 4 and second molding blocks 5 can be molded for different part sizes 8, thereby improving the applicability of the device. It can effectively replace the first molding block 4 and the second molding block 5 for different size requirements, realizing that a single mold can effectively meet multiple size requirements and greatly reducing the mold processing cost.

[0048] Specifically, the first detachable structure 9 includes a first limiting hole 91 formed on the upper template 1 and the first forming block 4, and a first limiting bolt 92 threadedly connected to the first limiting hole 91. The second detachable structure 10 includes a second limiting hole 101 formed on the lower template 2 and the second forming block 5, and a second limiting bolt 102 threadedly connected to the second limiting hole 101.

[0049] The first molding block 4 and the second molding block 5 are fixed to the upper template 1 and the lower template 2 using a first limiting bolt 92 and a second limiting bolt 102. This method facilitates disassembly and installation, allowing for quick replacement with new parts. This rapid replacement capability significantly reduces downtime and improves the overall operating efficiency of the equipment. The detachable bolted design makes component replacement and maintenance easy, thus reducing downtime losses due to equipment failure. Since the first molding block 4 and the second molding block 5 can be replaced individually, waste generated from the scrapping of the entire equipment is reduced. Furthermore, regular maintenance and replacement of worn parts extend the equipment's service life, thereby reducing the need for new equipment and energy consumption during manufacturing.

[0050] The foregoing has provided a detailed description of the aerospace anti-sway plate component forming device provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of this utility model.
