Abstract

The invention discloses a continuous stamping die for inner and outer sawtooth locking washers. The continuous stamping die is used for continuously stamping and forming the inner and outer sawtooth locking washers and comprises a positioning hole stamping die, an inner tooth hole stamping die, an inner tooth stamping die, an outer tooth hole stamping die, an outer tooth stamping die and a side cutting blanking die which are sequentially arranged in the feeding direction of a stamped profile. The inner and outer sawtooth locking washers with reliable and stable quality can be continuously manufactured on the premise that the inner and outer teeth are not deformed.

Description

technical field [0001] The invention relates to the technical field of machining tools, in particular to a continuous stamping die for inner and outer serrated lock washers. Background technique [0002] Serrated lock washers parts products have been widely used in aviation, aerospace and ships and other fields. Serrated lock washers generally include inner tooth serrated lock washers and inner and outer tooth serrated lock washers. The parts have great influence on locking performance, shape, size and quality The requirements are high, and it must be produced with the help of a mold. The general processing technology is: blanking-fitter punching through the wire hole and first-line cutting the shape and inner hole-pressing tooth forming-fitter repairing and grinding the mark-heat treatment to make it reach Oxidation or galvanizing passivation. When performing the above procedures, the blanking and punching are performed by the shape of the sheet metal, the inner hole is us...
