Sheet metal custom manufacturers need to follow sheet metal chassis processing standards
Table of Contents
Nowadays, sheet metal chassis processing has been widely emphasized. Still, in the process of processing, it is necessary to strictly follow the process and methods to ensure the quality of the process. During the processing and production of sheet metal chassis, the staff needs to have professional operating skills and a certain understanding of the structure and electrical devices of the equipment so that the standard requirements can be better met during the connection and application of the equipment.
During the processing of sheet metal chassis, it is also necessary to follow the physical and chemical design to achieve, through such ways and means, can ensure the structure of the sheet metal chassis achieves solid standards, but also to enhance the strength of the equipment. The processing operation also needs to focus on improving the impact and corrosion resistance of the product, which directly affects the equipment’s application. These issues should not be ignored during processing and production.
At present, the demand for sheet metal chassis processing is increasing. When processing production, selecting safety protection work is necessary to ensure the operation is completed within the safety range. In addition, equipment installation, operation, and maintenance must be carried out by standard processes. These are all process methods that need to be considered during processing operations.
In sheet metal chassis processing, production, assembly, and commissioning are also steps that cannot be ignored. Each procedure must be by the standards, which are all important in conducting the processing operation. Nowadays, the processing operation of sheet metal chassis will be developed strictly with the degree of specification and serialization. Conforming to these process standards is conducive to improving product quality. It can also provide more benefits for the practical application of the products, in line with the application needs of the industry.
General inspection standards for sheet metal chassis
1、The sheet metal chassis is not allowed to have tilt, partial distortion, or twist phenomenon visible to the naked eye. The verticality of the frame column and the base is less than 1.5mm, the upper surface of the base is used as the reference for inspection, and the inner edge of the upper end of the column is used as the measuring point.
2、The parallelism between the top frame and the base of the sheet metal chassis is less than 1mm, and the testing points are the top surface of the base and the bottom surface of the top frame, and they are the benchmark of each other. It can also be detected by measuring the length of the diagonal of the six sides, and the difference should not exceed 2.5mm. If there is a partition, the parallelism between the top frame and the base can be relaxed to 1.5mm, and the parallelism between the partition and the top frame or the base is less than 1mm.
3、The absolute value of the difference between the diagonal of the upper and lower enclosing frames of the sheet metal chassis is less than 1.5mm.
4、The columns of the sheet metal case cannot be twisted, and the parallelism between the intersection line of each column and the upper and lower enclosing frames and the adjacent plane of the enclosing frames is less than 0.5mm.
5、The parallelism of the working surface of the same layer’s left and right slideways relative to the base’s upper surface is 1mm. The sheet metal chassis should ensure that the absolute value of the difference between the gap between the two adjacent panels after the box insertion shall not exceed 0.6mm.
Technical requirements to be met for custom processing design of sheet metal chassis shell
Sheet metal chassis is a comprehensive cold processing process for thin metal plates (generally below 6mm). Its distinctive feature is the consistent thickness of the same part. Sheet metal case processing is the outer packaging of sheet metal cases. Standard sheet metal chassis shell processing are power, network, server, and outdoor cabinets. These are all made of sheet metal chassis material. So what technical requirements need to be met for the design of sheet metal chassis shell processing? Specifically, there are the following points.
1、The sheet metal chassis shell processing design should have good technical performance. For example, the structure of the power cabinet should be based on the electrical and mechanical properties of the equipment and the requirements of the use of the environment, a good physical design and chemical design to ensure that the structure of the cabinet has good rigidity and strength and good electromagnetic isolation, grounding, noise isolation, ventilation, and heat dissipation performance. In addition, the cabinet should have vibration resistance, impact resistance, corrosion resistance, dustproof, waterproof, radiation, and other properties to ensure the stability and reliability of equipment work.
2、 sheet metal chassis shell processing design should have good usability and necessary protection facilities to make the equipment easy to operate, install and maintain, safe, and reliable. For example, in the design of a machine tool sheet metal chassis shell, its structure, and layout should be reasonably designed, the overall design should be ergonomic, human-machine interaction design should be humanized, fully taking into account various safety hazards to ensure that the equipment is safe, reliable, easy and comfortable to operate.
3, sheet metal chassis shell processing should be easy to produce, assemble, commission, package, and transport. Generally speaking, the six steps of sheet metal chassis shell processing are drawing design, laser processing or (CNC stamping), bending, welding and molding, electrostatic powder spraying or (liquid paint), packaging, and shipping. The sheet metal chassis shell design should take into account the material process, processing procedures, production costs, and other factors so that the design meets the process requirements, the structure is easy to assemble, the product is easy to debug, and packaging and transportation, to ensure the feasibility of the design drawings, practicality, and economy.
4, sheet metal chassis shell processing design should align with the standardization, specification, and serialization requirements and ensure the performance of the equipment based on the pursuit of beautiful shape, application, and color coordination. The sheet metal chassis shell processing mainly plays the role of fixing and protecting the internal structure of the equipment. In the design, the sheet metal chassis shell processing should be designed according to the customer’s drawing or specific specification size, and meet the requirements of the internal structure design, to achieve easy processing, low cost, and beautiful.
Write at the end
Sheet metal chassis is currently a sheet metal processing product we widely use in electronic appliances, communication, the automotive industry, medical equipment, and other fields. However, no matter what kind of product, some relevant inspection standards exist, and sheet metal chassis are no exception. Only the sheet metal chassis that has passed these general inspection standards can be considered a quality sheet metal chassis.
