With the advancement of technology and the improvement of high-performance equipment, the complex processing technology in sheet metal manufacturing production is becoming increasingly mature. Sheet metal processing is widely used in various industries. From the electronics and automotive industries, communication engineering to the medical device industry, sheet metal is indispensable. Before purchasing an automated sheet metal production line, you must have an understanding of common sheet metal processing techniques.
What are the processing technologies in the sheet metal production line?
Sheet metal processing technology is a comprehensive cold processing technology for sheet metal processing. With the increasingly widespread 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 is necessary to meet the requirements of product functionality and appearance, and on the other hand, to simplify the model and production process, in order to achieve low production costs and high production efficiency.
The following mainly introduces the 24 common processes in sheet metal processing.
Blanking
Laser cutting machines or punch machines process materials according to programming files. Among them, laser cutting machines can meet the cutting needs of various shaped parts, while punch machines have advantages in batch processing.
Bending
According to the dimensions indicated on the bending icon, the workpiece is bent and formed using a bending machine. The bending die is divided into upper die and lower die. Different shapes require different molds. The accuracy of bending dimensions is determined by the quality of the mold
molding
Use a mold on a regular punch or other equipment to directly shape the workpiece into the desired shape. Most of them are formed by stamping and are widely used in the fields of automotive sheet metal and electronic products.
tapping
According to the bottom hole of the workpiece, machine the corresponding internal thread on the workpiece. Tapping has a requirement for the thickness of the plate, and if it is too thin, it can easily slip.
Counterbore
Process tapered holes on the workpiece. In order to have a good appearance without exposed screw heads, most workpieces are installed with countersunk holes.
Press riveting
Fasteners such as rivet nuts, screws, or nut columns should be firmly pressed onto the workpiece using a punch or hydraulic press. Pre opening bottom holes on the workpiece for riveting and pressing the fasteners onto the workpiece during bending can reduce welding workload and protect the appearance of special workpieces.
Stamped convex hull
A punch or hydraulic press uses a mold to form a convex shape on the workpiece, such as a punching shutter. Different shapes require different molds. Overall, it has a beautiful appearance and powerful functions.
printing
Use a mold to stamp text, symbols, or other shapes on the workpiece, mainly including company name, company logo, company website, and company contact number. Its advantage is that it can be permanently retained with the workpiece.
Punching net
Punch grid holes from the workpiece using a mold 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 rough edges on the surface of the workpiece can be removed using tools such as a grinder or file to make the machining area smooth and flat, preventing cutting scratches.
Argon arc welding
The connection between the workpiece and the workpiece is welded using an 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. Argon arc welding arc
