Sheet metal processing is the hinge technology that the sheet metal technician needs to grasp, and also is the important process of sheet metal products forming.Sheet metal processing is including traditional cutting blanking, cutting processing, bending forming method and the process parameters, such as cold and includes a variety of stamping die structure and technological parameters, all kinds of equipment, working principle and control method includes the new punching technology and new technology.Part metal sheet metal processing is called sheet metal processing.

According to the difference of sheet metal structure, the technological process can be different, but not more than the following.

1. Blanking: there are various ways of feeding, mainly in the following ways.

(1).Shearing machine: it is a simple material used for cutting the cutting strip of the cutting bed. It is mainly prepared for the mold blanking, with low cost and less than 0.2 precision, but can only be processed without the cutting Angle of the strip or block material.

(2).Press: is the use of punch points step or more open after the tablet on plate parts blanking forming various shapes, its advantage is cost time is short, high efficiency, high precision, low cost, suitable for mass production, but to design mold.

(3).NC NC blanking, the first to write all NC blanking NC machining program, using the programming software, pull map of writing into a number of NC machine tool can identify the program, make it according to the program step a knife on the plate blanking shape of the flat piece, but its structure by the cutting tool structure, low cost, precision at 0.15.

(4).Laser cutting, is the use of laser cutting way, in the structure of large flat it flat shape cut out, as well as NC blanking to write laser program, it can be a variety of complex shapes under flat parts, high cost, accuracy in 0.1.

(5).Sawing machine: mainly used aluminium profile, square tube, round tube, round bar material, low cost, low precision.

1.Fitter: sinker, tapping, reaming, drilling.

Sink hole Angle generally 120 ℃, for rivets, 90 ℃ for countersunk head screws, tapping the imperial bottom hole.

2.Flanging: also called pumping hole, hole, is in a small hole on the smoke into a larger hole, tapping again, mainly with the thickness of thin sheet metal processing, increase the strength and the screw thread turns, avoid sliding tooth, commonly used in thickness is thin, its around the normal shallow flanging, basic did not change, the thickness of thin thickness is allowed in the 30-40%, larger than normal flanging height can be obtained high height of 40-60%, with crowded thin 50% when, can get the biggest flanging height, when the thickness is bigger, such as the thickness of above the 2.0, 2.5, etc, can be directly tapping.

3.Press: is the use of mold forming processing working procedure, general processing of punching and cutting Angle, blanking, punching convex hull (convex point), salt tear, suction hole and forming processing, the processing needs to have the corresponding mold to finish operation, such as punching blanking die, convex BaoMo, tearing mode, pumping hole pattern, forming mould, etc., operating mainly pay attention to the position, direction.

4.Pressure riveting, riveting for the purpose of this company, mainly has the pressure riveting nut, screw, not to take off, etc, it is done through hydraulic pressure riveting machine or punch operation, the riveting to the sheet metal parts, and rose riveting way, need to pay attention to the direction.

5.Bending;Bending is to fold a 2D flat piece into a 3D part.Its processing needs to have the folding bed and the corresponding bending die to complete, it also has certain bending order, its principle is to the next knife does not produce the interference first fold, will produce the interference after the fold.
