What are the terms of sheet metal processing?
- Sheet metal processing terminology
1. Material shearing: refers to the process of obtaining a rectangular workpiece through a shearing machine.
2. Blanking: refers to the process of cutting workpieces with lasers or punching workpieces with CNC punching machines.
3. Blanking: refers to the process of processing the shape of the product with a mold on an ordinary punch or other equipment.
4. stamping: refers to the process of stamping workpieces with ordinary punches and dies.
5. Bending: refers to the process of forming the workpiece with a bending machine.
- Forming: refers to the process of deforming the workpiece by using a mold on an ordinary punch or other equipment.
7. Hole drawing: Also called “flanging”, it refers to the process of turning up the edge of the round hole on the workpiece with a die on an ordinary punch or other equipment.
8. Tapping: refers to the process of machining internal threads on the workpiece.
9. Reaming: refers to the process of machining small holes on the workpiece into large holes with a drill or milling cutter.
10. Countersunk hole: refers to the process of machining a tapered hole on the workpiece to match with a connector such as a countersunk head screw.
11. Riveting: refers to the process of firmly crimping fasteners such as riveting nuts, riveting screws or riveting studs on the workpiece with a punch or hydraulic press.
12. Riveting: refers to the process of first countersinking the workpiece, and then using a punch or hydraulic press to firmly crimp the rivet nut on the workpiece.
13. Pull mother: refers to a process similar to riveting. The process of firmly connecting connectors such as rivet nuts (POP) to the workpiece with a pull mother gun.
14. Pull riveting: refers to the process of tightly connecting two or more workpieces with pull rivets using pull rivet guns as tools.
15. Riveting: The process of connecting two or more workpieces face-to-face with rivets. For countersunk riveting, the workpieces need to be countersunk first.
16. Punching and convex hull: refers to the process of forming a convex shape on the workpiece with a die on a punch or hydraulic press.
17. Punching and tearing: also known as “punch bridge”, which refers to the process of forming a workpiece into a bridge-like shape with a die on a punch or hydraulic press.
18. Imprinting: refers to the process of using a mold to punch out characters, symbols or other imprints on the workpiece.
19. Corner cutting: refers to the process of cutting off the corner of the workpiece using a die on a punch or hydraulic press.
20. Punching mesh holes: refers to punching out mesh holes on the workpiece with a die on an ordinary punch or a CNC punch.
