Technological process of sheet metal processing machines:
Blanking: blanking die, laser cutting, plate cutting machine, digital punching.
Forming: number punching, number folding, forming mold.
Other processing: press riveting, tapping.
Welding: arc welding, resistance welding.
Surface treatment: powder spraying, electrophoresis, electroplating, etc.
Plate shears: used for cutting strip, mainly for the preparation of die blanking or blanking of simple parts with regular shape. Because of its high speed, low cost and low precision, it can only process strip or fast material without holes and corners. It can be changed quickly.
Laser cutting machine: high energy laser is used to irradiate the material to be cut, which makes the material gasified to produce cavities, and the beam moves to form slits. The structural shape of the parts is cut out. It is necessary to write a laser program to cut various parts with complex shapes. It has high cost and precision. It can be rapid prototyping.
Digital punch: a kind of automatic punch equipped with numerical control, which operates the punch action and processes parts through numerical control programming instructions. Through simple mold combination, it can complete a variety of complex hole patterns and shallow drawing parts at one time. It can also process large round holes, square holes, waist holes and curve profiles of various shapes by means of small die step punching. It can also carry out special processing, such as louver, counterbore, flanging hole, stiffener, stamping, etc. It can be changed quickly.
Press: a punch is a stamping press. Through the mold, it can make blanking, punching, forming, stretching, trimming, fine punching, shaping riveting and extruding parts. The processing accuracy depends on the nature of the mold and materials. Because the mold replacement and adjustment time is long, it is difficult to change the mold quickly.
CNC bending machine: it is a kind of equipment which can bend the thin plate through the mold, which has easy operation and can process the workpiece with side wall. It has high processing speed, high precision and automatic compensation function. It can be changed quickly.
