Do You Know The Blanking Methods For Automotive Sheet Metal Parts Fabrication?

With the increasing development of my country’s industrial level, sheet metal fabrication, as a fabrication method for cutting and blanking, has not formed a relatively complete definition in the industry. From the material characteristics of sheet metal fabrication alone, sheet metal fabrication is a comprehensive cold working process mainly for metal sheets below 6MM, and the relatively specific operations involved include shearing, punching/cutting/compounding, folding, welding, riveting, Splicing, forming (such as car body), etc.

Compared with other fabrication methods, the remarkable feature of sheet metal fabrication is that the thickness requirements of the same part are the same, which also makes sheet metal fabrication higher than general cutting fabrication requirements, and the use of CNC cutting machine equipment for sheet metal fabrication is also emerging in recent years. One way to get up, so what are the blanking methods for automotive sheet metal parts fabrication? What are the characteristics of each?

1. Shearing Machine Cutting

It is to use a shearing machine to cut out the shape, length and width of the expanded drawing. If there is punching or corner cutting, then turn the punching machine to combine the die punching and corner cutting to form.

2. Punch Blanking

It is to use a punching machine to punch the flat structure of the parts on the plate in one or more steps. Its advantages are short labor time, high efficiency, and can reduce fabrication costs.

3. CNC Cutting

When CNC blanking, the CNC machining program must be written first. It is to use programming software to write the drawn expansion diagram into a program that can be recognized by the CNC cutting machine. Let it follow these procedures step by step on an iron plate to punch out the structural shape of its flat parts. This type of fabrication method is currently widely used CNC cutting fabrication, and considering that the thickness of the fabrication material is mostly below 6MM, the most commonly used method is CNC plasma cutting.

4. Laser Cutting

It uses the laser cutting method to cut the structural shape of its flat parts on an iron plate.
