Embodiment Construction

[0025] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0026] Such as Figure 1 to Figure 3 Shown is a double-edge cutting blade processing technology for shredders, which is formed by stamping a continuous die with a 125T-250T press. The continuous die includes an upper die frame 2 with guide sleeves 1 on both sides and two sides respectively. A lower mold frame 4 with a guide post 3 mated with the guide sleeve 1, the upper mold frame 2 is provided with a fixed plate backing plate 5, a fixed plate 6, a stripping plate backing plate 7 and a discharge plate in sequence from top to bottom. The material plate 8 is elastically connected between the fixed plate 6 and the stripping plate backi...

Abstract

The invention discloses a paper shredder double-edge cutting blade and a machining process thereof. The cutting blade is machined and formed by a 125-250 T press machine stamping progressive die, an annular cutting edge punched by downwards pressing a coil cutter is used as an upper cutting edge, a leftover removal outline cutter is used for cutting the outline of a cutting blade body, a lower cutting edge is formed through stamping, and the paper shredder double-edge cutting blade with the two cutting edges is formed through machining. According to the paper shredder double-edge cutting blade and the machining process thereof, the design is reasonable, machining is convenient, the strength of the cutting blade can be effectively ensured, paper cutting and paper clamping are avoided, the production cost is effectively reduced, and machining resources are saved.

Description

technical field [0001] The invention relates to the field of paper shredders, in particular to a double-edged cutting blade of a paper shredder and a processing technology thereof. Background technique [0002] A shredder consists of a set of rotating blades, a comb and a drive motor. The paper is fed from the middle of the interlocking blades and is divided into many small pieces of paper to achieve the purpose of confidentiality. The basic working principle of commonly used pulverizing shredders is that the cutting blades and spacer rings are placed on the cutter shaft, and the motor and the gear device are used to drive two sets of parallel and relatively rotating cutter shaft pairs. The shear force formed will pass through the paper cut into pieces. [0003] At present, in the industry, cutting blades generally use single-edged cutting blades. Generally, two single-edged blades are mirror-symmetrical and superimposed to form a V-shape, so as to achieve the effect of cu...
