Problems to Be Considered when Designing the Structure of Sheet Metal Machining

What are the common key processes in sheet metal machining? The key processes of sheet metal machining include sheet design, drawing design, laser processing or CNC stamping dies, bending, electric welding, electrostatic spraying or (liquid architectural coatings) packaging and transportation.

1. The main points of designing the sheet metal machining

The key to the design of construction drawings of sheet metal machining is the dimension measurement, design scheme and expansion based on the engineering drawings or samples presented by the customer, and then the processing CAD part drawing is generated and submitted to the manufacturing solution unit. The sheet metal machining or laser processing can cut carbon steel, stainless steel and other raw materials with laser, using the method of fiber laser cutting. The workpiece processing section is clean and smooth, the appearance is beautiful and high-end, and the specifications are consistent. Curved products have many advantages, and basic CNC stamping dies are irreplaceable.

In addition, in the design of CNC stamping die for sheet manufacturers, some thin raw materials are also the key at this stage. Usually raw materials below 2.5 mm are more suitable. For products with porous structures and special housings such as die bases and cavities, CNC stamping dies have cost advantages in mass production.

Bending is also an essential part of sheet metal machining. Generally speaking, after the product is finished, the welded assembly after bending can be well guaranteed. In addition, in the process of sheet metal machining, welding forming is also an important factor affecting product quality. Generally speaking, after the raw materials are installed, they usually need to be assembled into product workpieces. There are various assembly methods, in some of which, they are assembled by non-welding methods with screws and rivets. The frame sheet metal parts are mostly formed by electric welding, and the products are firm and beautiful.

2. Issues that should be considered in the structural design of the sheet metal machining

In the process of sheet metal machining, many materials are used, such as machine tools, cabinets, boxes, etc. Due to the special material properties and processing requirements of the sheet metal itself, there are strict requirements on the structural design of sheet metal products.

(1) The structural design of sheet metal machining should ensure the realization of product functions and conform to the principle of economy and practicality. The structural design of sheet metal machining should follow the principle of economy and practicality. On the basis of ensuring quality and performance, in terms of sheet metal machining, the cost input in the manufacturing process should be reduced as much as possible.

(2) The structural design of sheet metal machining should consider the requirements of the product's use environment, and carry out protection design for the product in terms of waterproof, dust-proof and shock-proof. For example, in the design of sheet metal machining for cabinet equipment, it is necessary to select appropriate materials, select the appropriate surface treatment technology, and improve the performance of products such as corrosion resistance, mildew resistance, wear resistance, high temperature resistance, and light resistance through the stable seals of great structural design so as to enhance the environmental adaptability of products.
