Sheet metal processing is called sheet metal fabrication. For example, sheet metal is used to make chimneys, drums, fuel tanks, ventilation ducts, elbows, round and square heads, funnel shapes, etc. The main processes include shearing, bending, buckling, bending, welding, riveting, etc., which require certain geometric knowledge. Sheet metal parts are thin plate hardware parts, that is, parts that can be processed by stamping, bending, stretching, etc. A general definition is parts whose thickness remains unchanged during the processing process. Corresponding to them are castings, forgings, machined parts, etc.
Every industry has its own professional terms, and the sheet metal processing industry is no exception. The following 25 are common:
(1) Press riveting: refers to the process of using a punch or hydraulic press to firmly press fasteners such as press rivet nuts, press rivet screws or press rivet nut columns onto the workpiece.
(2) Riveting: refers to the process of first countersinking the workpiece and then using a punch or hydraulic press to firmly press the press rivet nuts onto the workpiece. (3) Riveting: refers to the process of using a process similar to riveting. The process of firmly connecting a rivet nut (POP) or other fasteners to a workpiece using a rivet gun.
(4) Riveting: refers to the process of tightly connecting two or more workpieces together using a rivet gun.
(5) Riveting: refers to the process of connecting two or more workpieces face to face with rivets. If it is countersunk riveting, the workpiece must be countersunk first.
(6) Corner cutting: refers to the process of using a die on a punch press or hydraulic press to cut the corners of the workpiece.
(7) Bending: refers to the process of forming a workpiece by a bending machine.
(8) Forming: refers to the process of deforming a workpiece by using a die on an ordinary punch press or other equipment.
(9) Shearing: refers to the process of obtaining a rectangular workpiece by passing the material through a shearing machine.
(10) Blanking: refers to the process of cutting the workpiece by a laser or a CNC punch press. (11) Blanking: refers to the process of using a die to process the product shape on a common punching machine or other equipment.
(12) Punching: refers to the process of processing a hole on a workpiece using a common punching machine and a die.
(13) Embossing: refers to the process of using a die on a punching machine or a hydraulic press to form a convex shape on a workpiece.
(14) Tearing: also called "bridge punching", refers to the process of using a die on a punching machine or a hydraulic press to form a bridge-like shape on a workpiece.
(15) Hole extraction: also called "flanging", refers to the process of using a die on a common punching machine or other equipment to form a round hole edge on a workpiece.
(16) Tapping: refers to the process of machining an internal thread on a workpiece.
(17) Leveling: refers to the process of using other equipment to level the workpiece if it is uneven before and after processing.
(18) Backthreading: refers to the process of repairing the thread of a pre-tapped workpiece for a second time. (19) Drilling: refers to the process of drilling holes in a workpiece using a drill bit on a drilling machine or milling machine.
(20) Chamfering: refers to the process of processing the sharp corners of a workpiece using a mold, file, grinder, etc.
(21) Stamping: refers to the process of punching out text, symbols or other marks on a workpiece using a mold.
(22) Countersinking: refers to the process of machining a tapered hole on a workpiece to fit a fastener such as a countersunk screw.
(23) Flattening: refers to the process of making a workpiece with a certain shape smooth.
(24) Mesh punching: refers to the process of punching a mesh of holes in a workpiece using a mold on a conventional punching machine or a CNC punching machine.
(25) Hole enlarging: refers to the process of machining a small hole on a workpiece into a large hole using a drill bit or a milling cutter.
