Cabinets generally refer to items used to store computers and related control equipment. They can provide protection for storage equipment, shield electromagnetic interference, realize orderly and neat arrangement of equipment, and facilitate equipment maintenance. With the continuous enhancement of my country's industrialization, sheet metal structure cabinets are widely used in scientific research, electronics, national defense and other fields. Doing a good job in the design of the cabinet with sheet metal structure is of great significance for enhancing the working performance of the cabinet and improving its quality.

First, the advantages of sheet metal structure cabinets

The cabinet of sheet metal structure is generally composed of base, upper cover, front and rear doors, front and rear frames, side doors, angle gauges, beams and other parts. It adopts an assemblable structure, which is simple to assemble, safe to connect, and convenient to move;

The angle gauge of the sheet metal cabinet can be treated with color zinc plating, which can ensure the safe grounding of the equipment;

The sheet metal structure cabinet adopts an enhanced fixed tray with strong load-bearing capacity;

The fan shell of the sheet metal structure cabinet is formed at one time, and the vibration of the fan is reduced;

The front and rear doors are high-density meshes, which effectively shield the internal equipment of the cabinet;

The surface of the sheet metal cabinet is sandblasted and plastic sprayed, which has strong acid and alkali resistance and corrosion resistance.

Second, the specific structure type of the sheet metal structure cabinet

According to the frame type of the cabinet, it can be divided into two types: column and beam combined type and whole board type;

According to the angle connection method of the sheet metal cabinet, it can be classified into four types: screw connection, adhesive connection, pin connection and welding connection.

Third, the technical requirements that the sheet metal structure of the cabinet should meet in the design process

The sheet metal cabinet must have good technical performance, and be able to effectively resist vibration, corrosion, impact, waterproof, dust, radiation, etc., to ensure that the equipment placed in it can work stably;

The design of the sheet metal structure cabinet should have good safety protection measures and good usability, which can facilitate people's installation, maintenance and operation, and ensure the safety of operators;

The cabinet design should be conducive to the ventilation and heat dissipation of the equipment to reduce the problems that occur in the use of the equipment;

The design of sheet metal cabinets should meet the requirements of standardization, serialization, and standardization, and reduce the cumbersome work of making cabinets according to drawings;

The design of the sheet metal structure cabinet must meet the requirements of electromagnetic compatibility to ensure that the equipment can guarantee the working performance in the limited space resources of the cabinet;

The cabinet design of sheet metal structure should be beautiful in appearance, economical and applicable, and the appearance and color matching should be coordinated.

Fourth, the design work of sheet metal structure cabinets need to pay attention to issues

(1) The requirements for production materials are clearly defined in the design drawings

It is necessary to make good material selection requirements, ensure that high-quality materials produced by regular manufacturers are selected, ensure that the materials can meet the requirements of relevant standards in actual production, and ensure that the design product can meet the design performance requirements; in the design, the cabinet production should be strictly controlled. Under the premise of ensuring the performance of the cabinet, reduce the cumbersomeness of the actual production process of the cabinet and enhance the operability of the design drawing; ensure that the selected material has good strength, is easy to bend, and is easy to shape .

(2) The design should meet the principles of economy and practicality

The design of the sheet metal structure cabinet should conform to the principle of economy and practicality. On the basis of ensuring the safe use of the cabinet, the quality of use, and the performance of the cabinet, the cost investment in the manufacturing process of the cabinet should be reduced as much as possible.

(3) The size design of the sheet metal structure cabinet

The size of the cabinet design should be determined in strict accordance with the size of the equipment stored in the cabinet, and the space required for the installation and setting of the various components required for the equipment work should be fully considered; attention should be paid to the operation actions, height, and body shape of the equipment users The understanding of the elements to ensure that the designed cabinet is easy to use by the operator; the design drawings try to use general size data to reduce the complexity of data conversion in the actual cabinet production; the design size of the sheet metal structure of the cabinet must strictly comply with the requirements of relevant standards .

(4) Design of the curved structure of the cabinet

The bending structure design of the sheet metal structure cabinet must follow the conventional bending structure data of the fabricated material to ensure that the degree of bending is within the range of the bending performance of the fabricated material to avoid damage to the material; if the thickness of the fabricated material is equal to or more than 2.5mm , Should pay attention to design a 1t-1.5t wide process gap.

(5) Shell design of sheet metal structure cabinet

The shell design of the sheet metal cabinet should fully consider the performance, protection and maintenance requirements of the equipment stored in the cabinet to ensure the normal use of the equipment; design a suitable shell type according to the specific use conditions of the equipment and the cabinet to ensure that it is under different conditions The safety and stability of the use performance of the cabinet; the cabinet shell design should ensure the best angle of operation and maintenance for the equipment users and maintenance personnel.

(6) The design of the sheet metal structure cabinet should meet the installation and use requirements of the equipment

The ultimate goal of the design of a sheet metal structure cabinet is to better play the role of the cabinet and ensure the safe and stable use of the equipment in the cabinet. In the process of designing the cabinet, not only the maintenance and repair requirements for equipment storage must be considered, but also the equipment must be satisfied. In terms of installation and use, it is necessary to clarify the specific installation and wiring requirements of the equipment stored in the cabinet, so that the cabinet design meets the requirements of the wiring of the equipment and the connection of various components.

(7) Aesthetic decoration and color matching

In the design process of the sheet metal structure cabinet, attention should be paid to the aesthetic design of the cabinet, so that the appearance design of the cabinet can give people a sense of beauty in terms of proportion, color, shape, and shape, and meet the aesthetic needs.

Conclusion:

With the continuous improvement of the level of social and economic development, the use of sheet metal cabinets has become wider and wider, and the society has higher and higher requirements for the performance of sheet metal cabinets. The design of sheet metal structure cabinets should understand and master the design guidelines of sheet metal structure cabinets and the issues that should be paid attention to in the design to ensure that the advantages of sheet metal structure cabinets are fully utilized.
