Description

Technical Field

[0001] The invention belongs to the technical field of box processing, and in particular relates to a method for preparing an outdoor inverted box. Background Art

[0002] In modern industrial manufacturing, the design and production of cabinets have always occupied an important position. The traditional inverted cabinet mainly adopts the bending and welding grinding process, which is widely used in the manufacture of housings for electronic equipment, mechanical parts and other products. This method forms a closed structure by bending the sheet metal material into the shape of the cabinet, then connecting the sides by welding, and finally grinding and waterproofing. The traditional bending and welding process has certain advantages. First, the bending process is relatively simple, and cabinets of different shapes and sizes can be produced as needed. Secondly, the welding process provides reliable structural strength to ensure the durability of the cabinet during use. In addition, the grinding process not only improves the appearance, but also reduces the burrs and sharp edges caused by welding, which improves the safety of users. Finally, the use of glue seals can effectively prevent water leakage, thereby protecting the internal equipment from the influence of humid environments.

[0003] Although the traditional inverted box has met the market demand to a certain extent, its shortcomings are becoming increasingly prominent. First, the welding process is not only time-consuming, but also has high technical requirements. The quality of welding directly affects the strength and sealing performance of the box. Problems such as uneven welds and pores that may occur during welding will lead to weak structures or water leakage. Secondly, the grinding process after welding is completed takes a lot of time and manpower, which increases production costs. During the production process, operators need to carefully grind the welding position to ensure a smooth appearance, which often easily leads to an increase in the defective rate. In addition, the dust and waste generated by grinding will have a certain impact on the environment, increasing the environmental burden in the production process. Third, the practice of glue sealing after welding to prevent water leakage can solve the problem of sealing to a certain extent, but this method still has hidden dangers. The effectiveness of glue sealing depends on the uniformity of glue application and environmental conditions. If the glue is unevenly applied or carried out under humid conditions, it may lead to poor sealing, which in turn affects the service life of the box. At the same time, the glue sealing material itself may age over time, causing sealing failure, increasing the complexity and cost of later maintenance. In mass production, the production efficiency of the traditional inverted method is relatively low. The relatively cumbersome welding and grinding process makes the production cycle of each box longer. In addition, welding operations require a certain number of technicians, which increases the dependence on human resources and reduces the flexibility of the production line. In the case of rapid changes in market demand, production response speed is particularly important.

[0004] A new production process still needs to be developed to meet the growing market demand. Summary of the invention

[0028] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the embodiments, but the present invention is not limited to these embodiments.

[0029] In a first aspect, some embodiments of the present invention provide a method for preparing an outdoor inverted box, comprising the following steps: S1: Cutting: Cutting the flat material according to the simulation results; S2: stretching: stretching the four sides of the flat plate material to obtain a blank; S3: Punching: Punch the blank according to product requirements and cut off the excess material at the four corners; S4: Punching the four R corners of the punched blank inwards to round the corners, and punching the edges of the rounded blank inwards to obtain an outdoor inverted box; or, The edge of the punched blank is punched inwards to form a straight edge, and the four R corners of the blank after the straight edge is punched inwards to form a rounded corner.

[0030] It can be understood that the present invention adopts full-process mold production, the whole process is highly automated, and production time and labor costs are greatly reduced. Through the one-time forming stretching die, the cumbersome multi-process in the traditional process is avoided, and the production efficiency is improved.

[0031] It should be noted that the box body formed by the stretching and bending process in the preparation method of the present invention has a more stable structure and good sealing performance, and can be effectively waterproof when adapted to outdoor environments, meeting the stringent requirements of C4H environments. This design ensures the durability of the product in long-term use.

[0032] It can also be understood that the present invention eliminates the welding, grinding and gluing processes, reduces the uncertainty caused by human operation, and reduces the defective rate. At the same time, it avoids the loss of material strength caused by welding and the environmental pollution caused by grinding, which conforms to the modern environmental protection concept.

[0033] Furthermore, the box produced by the preparation method of the present invention is precisely designed to meet a variety of outdoor application scenarios, has good weather resistance and corrosion resistance, and ensures long-term use in various extreme environments.

[0034] In addition, the preparation method of the present invention simplifies the overall process, reduces material loss, optimizes the production process, and further reduces production costs, making the product more competitive in the market.

[0035] Therefore, the preparation method of the present invention not only improves production efficiency and product quality, but also meets modern sustainable development requirements and has significant economic and technical advantages.

[0036] In combination with the first aspect, in some embodiments of the present invention, the flat plate material includes at least one of Al5052, SGCC, SPCC, SECC and SUS304 tensile plate.

[0037] By including a variety of materials, users can choose the most suitable material according to specific application requirements, which improves design flexibility. Diverse material options can reduce production costs, and users can choose the right material according to their budget without affecting the overall quality. The diversity of materials enables the cabinet to be used in a wider range of application scenarios, including reliability in extreme environments and meeting specific standards such as C4H. Choosing recyclable or environmentally friendly materials can improve the sustainability of the product, reduce environmental impact, and comply with modern environmental trends. Products that provide a variety of material options can attract a wider customer base, enhance market competitiveness, and meet the personalized needs of different customers. As a result, the diverse selection of flat panel materials brings significant flexibility and advantages to the design and application of outdoor inverted cabinets.

[0038] In combination with the first aspect, in some embodiments of the present invention, the thickness of the flat plate material is in the range of 0.5-3.0 mm.

[0039] Appropriate thickness can provide sufficient structural strength and toughness to ensure that the box will not be easily deformed or damaged under various external impacts and loads. Through reasonable thickness selection, the overall weight can be controlled while ensuring strength, making the product easier to carry and install, and improving user experience. Materials of different thicknesses may differ in price. Reasonable thickness selection can effectively reduce material costs while meeting performance requirements. The appropriate thickness range also helps to improve thermal insulation performance, ensure the stability of equipment inside the box under different temperature environments, and protect its normal operation. Increasing the thickness of the material can enhance the protection ability, improve the resistance to corrosion, wear and other environmental influences, and extend the service life of the product. Different thickness options provide more flexibility for design, and can be customized according to specific application scenarios or user needs to improve market adaptability. In addition, materials in a specific thickness range are usually easier to handle during processing and molding, improve production efficiency, and reduce processing difficulty. As a result, the thickness range of flat materials provides products with multi-faceted performance optimization and economic benefits, making them more suitable for various application scenarios.

[0040] In combination with the first aspect, in some embodiments of the present invention, in step S2, stretching is performed by a hydraulic press, and the process parameters include: 100-2000T.

[0041] The hydraulic press can provide stable pressure control, achieve high-precision stretching and forming, ensure that the blank meets the design requirements, and reduce errors. The automated operation of the hydraulic press can speed up production and shorten the forming time, thereby improving overall production efficiency and meeting the needs of mass production. During the hydraulic forming process, the pressure is evenly applied, which can effectively avoid material stress concentration, reduce the risk of material deformation or rupture, and improve the quality of the finished product. Through the precise forming process, the hydraulic press can minimize material waste, improve material utilization, and reduce production costs. In addition, the hydraulic press can handle a variety of different types of materials and has strong adaptability, so that stable forming effects can be maintained in a variety of applications. Furthermore, the operation of the hydraulic press is relatively safe, which reduces the necessity of manual intervention and reduces the safety risks of workers during operation. By using a hydraulic press for stretching, production efficiency, forming accuracy, and material utilization can be significantly improved, thereby enhancing the economy and reliability of the entire preparation process.

[0042] In combination with the first aspect, in some embodiments of the present invention, in step S3, the punching process parameters include: 1.0-10.0 mm.

[0043] In combination with the first aspect, in some embodiments of the present invention, in step S4, the process parameters of the rounded corners include: R2-R50mm, and the inner folding plane width is 5-15mm.

[0044] In combination with the first aspect, in some embodiments of the present invention, in step S5, the process parameters of folding the straight edge include: 10-30 mm, and the straight edge is used to place the waterproof tape.

[0045] In combination with the first aspect, in some embodiments of the present invention, the preparation method of the present invention further includes shaping the stretched blank between the stretching in step S2 and the punching in step S3.

[0046] Between the stretching of step S2 and the punching of step S3, the stretched blank is shaped. The shaping process can ensure that the stretched blank reaches the required processing size, avoid the subsequent process failure caused by material deformation, and help improve the consistency and reliability of the product. Further, through shaping, the minor defects that may occur during the stretching process can be eliminated, the flatness of the blank surface can be improved, and a good foundation can be laid for the subsequent punching and bending processes, thereby improving the appearance quality of the overall product. In addition, the shaped blank is easier to align and position during punching, reducing the risk of positioning errors, making the punching process smoother and improving production efficiency. Furthermore, shaping can ensure the rational use of materials before punching, reduce material waste caused by inappropriate size or incorrect shape, and thus improve economic benefits. The shaping process also helps to enhance the overall stability of the blank, reduce stress concentration that may occur in subsequent processes, and thus improve the structural strength and durability of the final product. By adding a shaping step between stretching and punching, the processing parameters can be flexibly adjusted according to different product requirements to adapt to the production of boxes of different models or specifications. Therefore, the addition of the shaping step not only improves production efficiency and product quality, but also optimizes the entire preparation process, enhancing process flexibility and material utilization.

[0047] According to some embodiments of the present invention, the outdoor inverted box is an integrally formed box.

[0048] The one-piece design eliminates welding and connection points, has stronger integrity, can effectively resist external impact and pressure, and improves the durability and anti-destruction ability of the structure. Due to the absence of welding gaps and seams, the sealing of the box is significantly improved, which can effectively prevent moisture and dust from entering the interior and meet the protection needs of outdoor use. The one-piece molding process is relatively simple, which reduces the complexity of multiple processes, shortens the production cycle, improves production efficiency, and reduces production costs. Due to the integrity of the structure, the probability of failure of the box during use is low, reducing the need for maintenance and repair, thereby reducing the long-term use cost. The one-piece molding design allows more complex and innovative shapes, so that the box not only meets the needs in terms of function, but also can be more attractive in appearance design, enhancing the market competitiveness of the product. The box prepared by the present invention can better adapt to various extreme environmental conditions, including temperature changes, humidity fluctuations and chemical corrosion, etc., to ensure long-term stability in a C4H environment. The one-piece molding production process is usually accompanied by less material waste and lower energy consumption, which meets the requirements of modern sustainable development and reduces the impact on the environment. Therefore, the one-piece molding design of the outdoor inverted box provides multiple advantages in strength, sealing, production efficiency and environmental adaptability, making it more competitive and with greater application potential in the market.

[0049] In combination with the first aspect, in some embodiments of the present invention, the C4H environmental weather resistance time of the outdoor inverted box is ≥10 years.

[0050] "C4H environment" generally refers to specific environmental condition standards, especially in military and industrial applications. Specifically, it involves the performance requirements of materials and equipment in various harsh environments, especially chemical, physical and climatic conditions. Among them, "C" represents the presence of chemicals or chemicals, which may include corrosive substances; "4" generally represents the four dimensions of extreme or change of the environment, such as temperature, humidity, pressure and pollutants; "H" represents high humidity or other specific climatic conditions.

[0051] In this environment, the material needs to have strong corrosion resistance, high temperature resistance, high humidity resistance and other properties to ensure its reliability and stability in long-term use. The C4H environmental standards are usually applied to the design and testing of military equipment, outdoor facilities and some specific industrial products. It can be understood that weather resistance ≥ 10 years ensures that the cabinet maintains stable performance in various harsh environments (such as high humidity, salt spray, chemical corrosion, etc.), reducing the risk of failure caused by environmental factors.

[0052] In addition, long-term durability reduces the need for frequent replacement or repair, reduces maintenance costs and manpower input, and improves overall economic benefits. Products with excellent weather resistance can enhance customers' trust in the brand, improve market competitiveness, and attract more users to choose. Cabinets with strong weather resistance can be used in a variety of outdoor application scenarios, such as military, transportation, energy and other fields, expanding market potential.

[0053] The extended service life means less material waste and resource consumption, which helps to reduce environmental impact and meet sustainable development goals.

[0054] Long-lasting weather resistance can ensure the safety of internal equipment and reduce equipment damage caused by the external environment, thereby ensuring safety during use.

[0055] By ensuring the weather resistance of the C4H environment reaches ≥10 years, this design not only enhances the overall value of the product, but also brings a more reliable usage experience to users.
