A: mold clearance;
The center line of the intensive not overlap;
The blade wear dull mould work.
The general principles of the 16: mold design is what?
A: under the premise to ensure the quality of stamping for the design of the mould, simple easy to manufacture, process, lower cost, easy to use.
17: the purpose of calculating rolling force?
A: is to correctly choose rolling equipment.
18: what call free bending?
Answer: when the bending punch, blank and die at the end of the match after impact won't happen again.
19: what is bending correction?
A: refers to the punch, blank and die, there was another shock after the agreement, the correction of bending parts.
20: what defects are prone to suppress head?
A: wrinkling and package;
Straight pull mark pit;
The surface micro cracks;
The longitudinal tear;
Above is the common term of mechanical parts processing, everyone know?
