In the punch on the mold should pay attention to what In the punch on the mold should pay attention to what In the cold stamping process, the material (metal or non-metallic) processed into parts (or semi-finished products) of a special process equipment. Cold stamping die is a cold stamping die. The following describes the installation of the mold on the punch Note: First, the installation should first confirm the sharp edge of the mold, concave die edge does not collapse, the punch is not missing angle. If there is a chink or missing angle, first sharpen the knife. Second, before the mold should be in the upper and lower mold between the pad into a silicon steel sheet to prevent the collision process due to injury blade. Third, in the mold before loading the punch, the use of Whetstone to the underside and the top of the burr worn off, with a cloth to clean up the garbage. If there is burr or rubbish on the upper and lower surfaces of the mold, it will cause the burr tolerance of the die. Fourth, adjust the slide stroke to the appropriate position Compaction on the mold, mold or mold must ensure that the plane on the bottom surface of the slider in close fit, the next pressure plate screw gently pressed.

Then, adjust the slider up to remove the middle silicon steel sheet. Loosen the lower mold plate screw welding machine for plate, adjust the slider downward until the punch enters the die 3 ~ 4mm, press the lower mold plate screw. New die punching punch must enter the die 3 ~ 4mm, otherwise, there must be punch die or concave die burst. Fifth, raise the slider to the top dead center position, adjust the punch to stop the screw metal hole punch machine, to the elastic appropriate, and then idle several times to observe the mold and punch the work of the institutions are normal. If there is no exception angle iron drill, you can start production. More related: punch cold stamping die processing of the main processes
