Technology for processing blank of paper shredding blade and processing device of technology

Abstract

The invention discloses a technology for processing a blank of a paper shredding blade. The technology is used for processing a metal material strap into a strap blank of the paper shredding blade, and comprises the steps as follows: 1), the metal material strap is provided; and (2), the metal material strap is processed with a rolling technology, so that the strap blank with unchanged width is formed; a plurality of concave pits and separation walls for separating the concave pits are formed in one side surface of the strap blank; and the separation walls are strip-shaped and staggered mutually, so that the side surface is net-shaped. Compared with the prior art, the processed strap blank not only is high in strength, but also saves materials. Besides, the invention further discloses a processing device of the blank of the corresponding paper shredding blade.

Description

technical field [0001] The invention relates to the field of jig processing, in particular to a processing technology and processing equipment for processing shredded paper blade stock. Background technique [0002] In the corporate office, many used and discarded papers, because the information recorded on them are corporate secrets, in order to prevent others from obtaining the information recorded on the documents, the paper needs to be shredded, so the paper shredder came into being. A traditional paper shredder generally includes two cutter shafts and several pairs of shredding blades fixed on the cutter shafts. When shredding paper, the motor drives a series of transmission mechanisms to transmit a lower speed and a larger torque to the cutter shaft to rotate the two cutter shafts. When the paper passes between the two rotating cutter shafts, the two cutter shafts squeeze the paper. In this way, the waste paper is cut into thin strips or shreds. [0003] In order to ...

AI Technical Summary

Problems solved by technology

Because the thickness of the blade itself is too thin, the finished product often needs to fix the part where the blade tip is connected with the blade body or perform curling treatment to strengthen the strength of the blade tip, and the process is complicated; and in order to save materials, the above-mentioned hollow The blank thickness of the paper blade is far thinner than that of the solid shredding blade, and the blade body of the hollow shredding blade is only bonded together by a few bumps, so the strength is poor, so it can only be used to cut a small amount of paper and Short life, easy to deform

[0005] From the processing procedures of the above two shredding blades, it can be seen that the blank used for processing the shredding blade is an important factor affecting the strength and material consumption of the shredding blade, and the existing shredding blade blanks often use thickness Consistent and smooth metal plates on both sides, in order to ensure the same thickness of the blanks of this type of shredding blade, the existing blank processing technology must use cold rolling equipment specially for processing steel for several times of rolling processing, which will inevitably increase the thickness of the shredding blade blank processing difficulty and processing cost

Moreover, if the thickness of the shredding blade blank is thicker, more materials are needed and the cost is high; if the thickness is thinner, the shredder blade produced has poor strength, short service life and is easily deformed.
