Do you know sheet metal processing?

First, when bending according to the dimensions in the drawing of, material thickness when bending and Groove, avoid collision-induced deformations are with the tool die selection key (in the same product, on different types of mold may be used), the lower the selection determined by the thickness of the plate. Next is to determine the sequence of bend, bend outside the general rule after the first, small at first and then, after the first special General. To kill the edge of the workpiece first workpiece bending to the 30 °-40 °, and artifacts crushed to death with leveling mode.
When clinching, taking into account the height of the stud the same different molds, and then adjust pressure on the press to ensure flush Stud and workpiece surface to avoid studs did not fasten or pressure over the workpiece surface, causing scrapped the workpiece.
Welded with Tig welding, spot welding, carbon arc welding, shielded metal arc welding, spot welding first consider workpiece welding position, consider positioning in the production tooling to ensure accurate spot location.
In order to weld solid, to be welded on the workpiece play bump, you can make the bump in power on contact with the plate even before soldering, to ensure the heat also can determine the position, again, to welding, adjusted the preload time dwell time, duration, stop time, ensure the workpiece can spot welding firm.
After welding in the welding scar surface occurs, be treated with flat grinding machine, argon arc welding is mainly used for large two workpiece and when connected together, or the edge of a workpiece handling, reach the surface flat and smooth. Argon arc welding of heat deformation of the workpiece can be easily, after welding the grinding mill machine peace process, especially the corners more often.
