Abstract

The invention discloses a paper shredding blade machining method. A paper shredding blade comprises a blade body, a mounting hole positioned at the center of the blade body, and a point positioned on the periphery of the blade body. The method comprises the following steps: providing a forming die with a die cavity of the shape of the paper shredding blade and providing an annular metal blank with the size being slightly larger than or the same with that of the paper shredding blade, arranging the annular metal blank into the die cavity, performing plastic forming machining to the annular metal blank, ensure that the annular metal blank is subjected to plastic deformation to be filled in the die cavity, and forming the paper shredding blade. The method has the advantages of high material utilization and cost saving.

Description

technical field [0001] The invention relates to a shredding blade processing technology, in particular to a shredding blade processing method with high material utilization rate and cost saving. Background technique [0002] The shredding principle of the paper shredder is to fix several pairs of shredding blades on the two cutter shafts, and drive a series of speed change mechanisms through the motor to transmit a lower speed and a larger torque to make the two cutter shafts rotate. When the paper rotates from the two When passing between the cutter shafts, the two shredding blades cut the paper, thus cutting the waste paper into thin paper strips or shreds. Therefore, the shredding blade plays a very important role in the shredding effect of the shredder. [0003] The processing methods of the existing shredding blades are all stamping forming processing, and the stamping forming generally pushes the metal material belt forward in a step-by-step manner, and then punches o...
