1, first with a clean cloth to clean the surface of the outer covering parts, and then polished with oil stone (
20 * 20 x 100 mm or larger)
, have the place with circular arc and hard-to-reach places with relatively small abrasive polishing (
For example: 8 x 100 mm semicircle sharpening stone)
2, selection of abrasive particle size depends on the surface condition (
Such as roughness, galvanized, etc. )
Suggest using fine-grained whetstone.
Oilstone grinding basically along the longitudinal direction, and a good joint on the surface of the stamping parts and some special place can also supplement horizontal grinding.
Stamping is to rely on press and die for sheet, strip, pipe and profiles, such as external force, make its produce plastic deformation or separation, thus to obtain the required shape and size of the workpiece,
The forming method.
Stamping and forging belong to plastic processing (
Or pressure processing)
, called the forging press.
Stamping of billet is mainly hot rolling and cold rolling steel plate and steel belt.
