Detailed explanation of the main processes of sheet metal processing

Sheet metal processing includes traditional methods and process parameters such as cutting, punching, bending and forming, as well as various cold stamping mold structures and process parameters, various equipment working principles and control methods, as well as new stamping technologies and processes.

Common sheet metal processing techniques include:

(1) Riveting: refers to the process of firmly pressing fasteners such as rivet nuts, rivet screws, or rivet nut columns onto the workpiece using a punch or hydraulic press.

(2) Riveting: refers to the process of first sinking the workpiece into a hole, and then using a punch or hydraulic press to firmly press the rivet nut onto the workpiece.

(3) Pulling mother: refers to using a process similar to riveting. The process of firmly connecting riveted nuts (POP) and other connecting parts to the workpiece using a puller gun.

(4) Riveting: refers to the process of using a riveting gun as a tool to tightly connect two or more workpieces together with rivets.

(5) Riveting: The process of using rivets to connect two or more workpieces face to face together. If countersunk riveting is used, the workpiece needs to be countersunk first.

(6) Corner cutting: refers to the process of using a mold on a punch or hydraulic press to cut off the corners of a workpiece.

(7) Bending: refers to the process in which a workpiece is formed by a bending machine.

(8) Forming: refers to the process of using a mold on a regular punch or other equipment to deform a workpiece.

(9) Cutting: refers to the process of obtaining rectangular workpieces from materials through a shearing machine.

(10) Cutting: refers to the process of cutting a workpiece through LASER or CNC punching.

(11) Blanking: refers to the process of using molds to process the shape of a product on a regular punch or other equipment.

(12) Punching: refers to the process of machining holes on workpieces using ordinary punching machines and molds.

(13) Punching convex hull: refers to the process of forming a convex shape on a workpiece using a mold in a punch or hydraulic press.

(14) Punching and tearing: also known as "punching bridge", refers to the process of using a mold on a punch or hydraulic press to form a workpiece in the shape of a bridge.

(15) Punching: also known as "flipping", refers to the process of using a mold on a regular punch or other equipment to form a circular hole edge on the workpiece and flip it up. Process.

(16) Tapping: refers to the process of machining internal threads on a workpiece.

(17) Leveling: refers to the process of using other equipment to level a workpiece that is uneven before and after processing.

(18) Tooth restoration: refers to the process of repairing the second spiral tooth on a workpiece that has been pre tapped with teeth.

(19) Drilling: refers to the process of using a drill bit to drill holes in a workpiece on a drilling or milling machine.

(20) Chamfer: refers to the process of machining sharp corners of workpieces using molds, files, polishing machines, etc.

(21) Printing: refers to the process of using a mold to print text, symbols, or other marks on a workpiece.

(22) Countersunk hole: refers to the process of machining tapered holes on a workpiece to match connectors such as countersunk screws.

(23) Flattening: refers to the process of transitioning a workpiece with a certain shape to a flat surface.

(24) Punching holes: Refers to the use of a mold to punch a mesh of holes into a workpiece on a regular punch or CNC punch.
(25) Expanding hole: refers to the process of using a drill or milling cutter to process small holes on a workpiece into large holes.
