Problems solved by technology

Although the above-mentioned shredding blade 400 processing method is simple, it only needs to use a stamping die to directly cut off the waste material 301 on the material belt to obtain the required shape and structure of the shredding blade 400; however, this processing method has great limitations. The disadvantage is that the material utilization rate is low, and the production cost cannot be effectively reduced; the reason is that a certain distance needs to be reserved between the two shredder blades 400.

Example Embodiment

[0022] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following is a detailed description in conjunction with the embodiments and accompanying drawings.

[0023] Such as figure 2 , image 3 and Figure 4 As shown, figure 2 It is a paper shredding blade 100 processed by the processing method of the present invention. The paper shredding blade 100 includes a blade body 11, a mounting hole 12 at the center of the blade body 11, and a blade tip 13 at the periphery of the blade body. The stamping and forming method of the paper shredding blade 100 of the present invention includes the following steps: (S1) providing a metal strip 200, and pressing a pre-punch line on the metal strip 200 at a distance equal to the diameter of the paper shredding blade 100 201, forming a forming area 202 of the paper shredding blade 100 between two adjacent pre-pressed lines 201 on the metal strip; (S2) punching o...

Abstract

The invention discloses a paper shredding blade punching forming 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 metal material strap, pressing pre-pressing lines on the metal material strap at an interval of the diameter of the paper shredding blade, so as to ensure that a paper shredding blade forming zone is formed between each two adjacent pre-pressing lines on the metal material strap, punching the paper shredding blades on the paper shredding blade forming zones, ensuring that the paper shredding blades are connected with the metal material strap in positions of the pre-pressing lines, and disconnecting in the positions of the pre-pressing lines, so as to obtain independent paper shredding blades. 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 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] Today's shredding blades have a variety of processing methods, such as figure 1 As shown, it is an existing shredding blade processing technology, which includes the following steps: (...
