What are the processing technologies in the sheet metal production line?

Sheet metal processing technology is a comprehensive cold working technology for sheet metal processing. With the increasing application of sheet metal parts, sheet metal processing technology has become a very important part of the product development process. Designers need to master the process characteristics of sheet metal. On the one hand, it needs to meet the requirements of product function and appearance, and on the other hand, it is necessary to simplify the model and simplify the production process, so as to achieve low production cost and high production efficiency.

The following mainly introduces 24 common processes in sheet metal processing.

blanking

The laser cutter or punch machine processes the material according to the programmed file. Among them, laser cutting machines can meet the cutting of various shapes of parts, while punching machines have advantages in batch processing.

bend

According to the dimensions marked in the bending drawing, the workpiece is bent and formed by the bending machine. The bending die is divided into an upper die and a lower die. Different shapes require different molds. The accuracy of the bending dimension is determined by the quality of the mold.

forming

The workpiece is directly made into the desired shape using a die on a common punch or other equipment. Most of them are stamping and forming, which are widely used in the fields of automotive sheet metal and electronic products.

Tapping

According to the bottom hole of the workpiece, the corresponding internal thread is machined on the workpiece. Tapping has requirements on the thickness of the plate, and if it is too thin, it is easy to slip.

Counterbore

Machining taper holes in the workpiece. In order to have a good appearance and no exposed screw heads, the workpieces are mostly mounted with countersunk holes.

Pressure riveting

Fasteners such as rivet nuts, screws or nut posts should be securely crimped to the workpiece by a punch or hydraulic press. Bottom holes are pre-drilled on the workpiece for riveting, and the fasteners are pressed on the workpiece during bending, which can reduce the welding workload and protect the appearance of special workpieces.

Stamping convex hull

A punch or hydraulic press uses a die to shape the workpiece into a convex shape, such as punching a louver. Different shapes require different molds. Overall, it's nice looking and functional.

print

Use the mold to punch out text, symbols or other shapes on the workpiece, mainly including the company name, company logo, company website and company contact number. The advantage is that it can be permanently retained with the workpiece.

perforated mesh

Grid holes are punched out of the workpiece with a die on a regular punch or CNC punch. The mesh plate on the workpiece can play a beautiful decorative role and meet the heat dissipation function.

Deburring

The burrs on the surface of the workpiece can be removed with tools such as a grinder, a file, etc., so that the workpiece processing place is smooth and flat to prevent cutting and scratching.

TIG welding

The connection between the workpiece and the workpiece is welded by the argon arc welding machine at the edge or joint of the workpiece, which is divided into intermittent welding and full welding. It needs to be clearly marked on the drawing. TIG welding has stable arc combustion, high production efficiency, small welding deformation and convenient operation and observation.

Welding

The planting screw is firmly welded to the workpiece with a planting torch. Implant welding is often used on workpieces with less stress and requirements on the outer surface of the workpiece to ensure the beauty of the workpiece.

Welding and grinding

Use grinding machines, files and other tools to make the welding marks of the workpiece smooth and flat, so that a better molding surface can be obtained, and the adhesion of the subsequent plastic spraying powder can be increased.

preprocessing

After the workpiece is processed, before painting or powder spraying, the workpiece should be degreasing and rust removed with electrolyte, and a coating (such as phosphating film) should be added and cleaned on the surface of the workpiece to increase the adhesion of the subsequent powder spraying plastic.

Dusting and Grinding

Use putty to make up for defects on the surface of the workpiece, such as welding gaps or pits, and polish the surface of the workpiece after scraping with a surface grinder or emery cloth to increase the parallelism and aesthetic appearance of the entire workpiece, and further increase the adhesion of the spray powder.

brushed

It uses a wire drawing machine and an abrasive belt to texture the surface of the workpiece to increase aesthetics and market demand. Mainly stainless steel surface treatment.

polishing

Use polishing equipment to polish the surface of the workpiece to increase the aesthetics and surface finish, mainly stainless steel surface treatment.

heat treatment

In order to improve the hardness of the workpiece, the ultimate purpose of heat treatment is to improve the mechanical properties such as hardness, wear resistance and strength of the workpiece.

fuel injection

Spray the paint evenly on the surface of the workpiece with a spray gun, which is convenient, fast and easy to use.

spray

Spray the powder evenly on the surface of the workpiece with a spray gun and bake it in the oven. The sprayed workpiece has better wear resistance and corrosion resistance.

blackening

Chemical surface treatment is a commonly used method, which produces an oxide film on the metal surface to isolate the air and achieve the purpose of rust prevention.

screen printing

The special ink penetrates through a special grid to form text or patterns on the surface of the workpiece. Screen printing has a wide range of applications, long-lasting colors, and fast and convenient operation.

Laser Marking

The surface treatment is carried out using optical principles; the laser beam can engrave permanent marks on the surface of the workpiece in various shapes.

With the rapid development of industrialization, the processing and manufacturing of sheet metal parts is also developing in the direction of intelligence. As a coating for mechanical products, the quality of sheet metal parts also plays an important role. In order to ensure that the surface forming of sheet metal parts meets the requirements, the quality must be guaranteed from both surface quality and internal quality.
