Abstract

The invention discloses a method for machining paper shredding blades in a punching forming mode. Each paper shredding blade comprises a blade body, a mounting hole in the center of the blade body and blade points located on the periphery of the blade body. The method for machining the paper shredding blades in the punching forming mode comprises the following steps that a metal material band is provided, a plurality of paper shredding blades are formed on the metal material band through punching, and adjacent paper shredding blades are in a tangent state and are connected at the tangential position; blade cutting grooves are formed in the tangential positions of the paper shredding blade in a press mode, and thus blade cutting positions are formed in the blade cutting grooves; single bodies of the paper shredding blades are obtained by breaking at the blade cutting positions. The method for machining the paper shredding blades in the punching forming mode has the advantages of being high in material utilization rate and saving cost.

Description

technical field [0001] The invention relates to a shredding blade processing technology, in particular to a stamping and forming processing method of a shredding blade 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] Now there is a shredding blade processing technology, which includes the following steps: 1. Provide a metal strip with an appropriate width; 2. Punch out the mounting holes for the shr...
