Abstract

The utility model discloses a self sharpening beet slicing blade with long service life and non-perishable passivation. One end of a blade body of the utility model is provided with an outwards raised waveform edge port extending part; the top end of the outwards raised waveform edge port extending part is a cutting edge; the front face (outward face of the outwards raised waveform edge port extending part) is provided with a hard layer, and the hardness of the hard layer is larger than the hardness of the other inward face (rear face); the other end of the blade body is provided with not less than two fixed grooves used for installation. The utility model has the advantage of simple structure, and can sharpen automatically during operation; the utility model is easy to keep a sharp state to work, and the quality of beet slices which are cut is obviously improved; thus, loss in the process of beet sugar manufacture is reduced, and the production efficiency is enhanced.

Description

Self-sharpening beet slicing blade

The utility model relates to the shredding knife technical field that is used for beet slicing, is a kind of self-sharpening beet slicing blade.

The beet slicing blade is the requisite running stores of beet-sugar factory; Beet belongs to piece root fruit, contains a large amount of pectin, and the leaching of its sugar part need be carried out a process with hot-water soak to the dish silk; As fruit and vegetable silk gage distortion, broken silk amount greatly, thick cossettes sugar part does not also thoroughly bubble out, but thin and a large amount of broken cossettes are because oversoaking and soft mashed, pectin also bubbles out with sugar part, the rough crenellated phenomena that is prone to of cossettes the half congealed juice purity of leaching descended, if will fragment into broken silk soon in immersion, therefore, the quality of cossettes quality directly influences the production process of beet sugar manufacture; Causing one of ropy reason of cossettes is owing to the passivation easily in use of beet slicing blade, if the general replacing diffusion knife of frequency will reduce production efficiency; And the reason that makes the easy passivation of diffusion knife is because the hardness of diffusion knife is hanged down and caused, still, if the hardness of diffusion knife one height not only can easily cause the tipping phenomenon because of toughness descends, and sharpening is difficult to also carry out.

The purpose of this utility model is to overcome the deficiency of prior art and proposes a kind of long service life, is difficult for the self-sharpening beet slicing blade of passivation.

The purpose of this utility model realizes by following measure: an end of the cutter hub of this self-sharpening beet slicing blade has the waveform edge extendible portion of outside protrusion, and the top of edge extendible portion is a cutting edge, the outside one side of edge extendible portion is promptly positive, and one deck hardness is arranged is the hard formation at the back side greater than inside another side, and the other end of cutter hub has and is no less than two the pickup groove that is used to install; The thickness of hard formation is 0.15 to 0.20 millimeter; Positive hardness is that 55 degree are to 59 degree HRC; The hardness at the back side is that 10 degree are to 20 degree HRC.

Accompanying drawing 1 is the elevational schematic view of the utility model most preferred embodiment;

Accompanying drawing 2 is looked synoptic diagram for the master of accompanying drawing 1;

Accompanying drawing 3 is that the A-A of accompanying drawing 2 is to sectional view;

Accompanying drawing 4 is that the B-B of accompanying drawing 2 is to sectional view;

Accompanying drawing 5 is the vertical view synoptic diagram of accompanying drawing 2;

Coding in the accompanying drawing is respectively: 1 is cutter hub, and 2 is the edge extendible portion, and 3 is cutting edge, and 4 is the front of edge extendible portion, and 5 is the back side of edge extendible portion, and 6 is hard formation, and 7 is pickup groove.

Below in conjunction with most preferred embodiment and accompanying drawing the utility model is described in further detail:

As accompanying

drawing

1,2,3, shown in 4 and 5, one end of the cutter hub 1 of this self-sharpening beet slicing blade has the waveform edge extendible portion 2 of outside protrusion, and the top of edge extendible portion 2 is a cutting edge 3, promptly positive 4 one deck hardness is arranged is the hard formation 6 at the back side 5 greater than inside another side to the outside one side of edge extendible portion 2, thickness the best of its hard formation 6 is 0.15 to 0.20 millimeter, the hardness optimal in its front 4 is that 55 degree are to 59 degree HRC, and the hardness optimal at the back side 5 is that 10 degree are to 20 degree HRC, therefore, the utility model in use, its front 4 is difficult for being worn, and the back side 5 easily is worn, and so just easily keeps the acutance of cutting edge 3, and does not reduce toughness of the present utility model, thereby be not prone to the tipping phenomenon, thereby prolonged work-ing life; The other end the best of cutter hub 1 has two pickup grooves that are used to install 7, so that self-sharpening beet slicing blade is fixed on the beet slicer.

The utility model is simple in structure, after using this self-sharpening beet slicing blade, just energy self-sharpening at work, thereby within 72 hours, do not need the tool changing sharpening, thereby improved the chopping work efficiency, and the blade of changing is because of the lower easily sharpening of back side hardness, thereby can save sharpening greatly and can reduce loss to the sharpening instrument man-hour again; Because this blade easily keeps sharp state work, thereby makes the quality of the cossettes of cutting that significant raising arranged, and the loss in the beet sugar manufacture technology is reduced greatly, and improved production efficiency.
