Abstract
The utility model provides a grinder knife section for install on moving the fixing base of knife rest, each knife section semicircular in shape, including a vertical limit and an arc limit, its arc limit periphery is provided with the cutting tooth, and the setting of two semicircular knife sections symmetry forms a circular shape knife section after on moving the fixing base of knife rest jointly, so, the grinder forms the circular state that cuts up at during operation, each circular shape knife section to work is steady, and the arbor load is even, and each circular shape knife section cutting pitch is the same, thereby makes the length and the knife section wearing and tearing of being cut after the object cutting relatively more even unanimous, and two adjacent knife sections of circumferencial direction distance is moderate, thereby not only guarantees to cut up the effect but also be difficult for the centre gripping and the jam, thereby has reached the wearing and tearing that reduce the knife section and move the knife rest, the purpose that promotes the grinder reliability.
Description
Technical field
The utility model relates to grinder field of mechanical technique, is specifically related to a kind of grinder cutting blade.
Background technology
At present, along with the development of science and technology, every technical performance of all kinds of processing equipment obtains and promotes widely.
Existing grinder generally includes cutter shaft and is arranged on the cutting blade on cutter shaft.These cutting blades are generally employing symmetrically arranged single diamond shaped insert or the Y shape cutting blade that adopts flail knife formula to install side by side, these cutting blades in cutting process because of only relatively two sides cutting, make cutting force uneven, very easily there is job insecurity, vibratility is larger, do not enter amount large time easily occur clamp phenomenon, finally cause cutting blade and movable knife rack serious wear, reduce integral product reliability.
Therefore, how to reduce the wearing and tearing of cutting blade and movable knife rack, promote the reliability of grinder and become an industry letter technical barrier to be solved.
Utility model content
In view of this utility model is made, and for overcoming problems one or more existing for the grinder cutting blade of prior art, at least provides a kind of useful selection.
A kind of grinder cutting blade, for being arranged on the holder of movable knife rack, each cutting blade semicircular in shape, comprise a vertical edge and an arc-shaped side, its arc-shaped side periphery is provided with cutting teeth, the common cutting blade forming a circle after on the holder being arranged on movable knife rack of two semicircular cutting blade symmetries.
In the utility model, because of the common cutting blade forming a circle rear on the holder being arranged on movable knife rack of two semicircular cutting blade symmetries, so, grinder operationally, the cutting blade of each circle forms a circular chopping state, thus stable working, cutter shaft load is even, the cutting blade cutting pitch of each circle is identical, thus make the length after the cutting of cut material body and cutting blade wearing and tearing compare uniformity, and adjacent two cutting blades of circumferencial direction are apart from moderate, thus not only ensure chopping result but also not easily clamp and block, thus reach the wearing and tearing reducing cutting blade and movable knife rack, promote the object of grinder reliability.

Following detailed description of the invention will further illustrate the utility model in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
As shown in Figure 1, the grinder of the present utility model bolt 50 that comprises movable knife rack 10, cutting blade 30 and cutting blade 30 is fixed on movable knife rack 10.
The opposite end up and down of described movable knife rack 10 respectively interval be provided with multiple holder 11, be arranged on the holder 11 of upper end and be symmetrical arranged with the center line of the holder 11 of lower end about movable knife rack 10.
Please refer to Fig. 2, each cutting blade 30 described is the circular lamellar body of half, comprises an arc-shaped side and a vertical edge.The outer rim of arc-shaped side is provided with cutting teeth 31, a middle side part concave shaped Cheng Youyi seam 33 of vertical edge, for a part of accommodating movable knife rack 10 in interior and after avoiding cutting blade 30 to install and movable knife rack 10 interfere.In one embodiment, the relative both sides of the vertical edge of the lamellar body of cutting blade 30 offer installing hole 35 respectively, for passing for bolt or screw 50, thus are arranged on holder.But the mode that cutting blade is arranged on holder is unrestricted.
Please again consult Fig. 1, during described grinder combination, respectively semicircular cutting blade 30 is fixed on corresponding holder 11 by bolt or screw 50.Because the holder 11 of movable knife rack about 10 opposite end is symmetrical arranged, two corresponding semicircular cutting blades 30 are also symmetrical arranged and are combined to form the cutting blade of a circle.Now, the vertical edge of corresponding two semicircular cutting blades 30 mutually against, arc-shaped side forms a complete circular arc external surface, so, grinder operationally, the cutting blade of each circle forms a circular chopping state, thus stable working, cutter shaft load is even, the cutting blade cutting pitch of each circle is identical, thus make the length after the cutting of cut material body and cutting blade 30 wearing and tearing compare uniformity, and adjacent two cutting blades 30 of circumferencial direction are apart from moderate, thus not only ensure chopping result but also not easily clamp and block, thus reach the wearing and tearing reducing cutting blade 30 and movable knife rack 10, promote the object of grinder reliability.
Be understandable that, for the person of ordinary skill of the art, other various corresponding change and distortion can be made according to technical conceive of the present utility model, and all these change the protection domain that all should belong to the utility model claim with distortion.
Claims (4)
1. a grinder cutting blade, for being arranged on the holder of movable knife rack, it is characterized in that: each cutting blade semicircular in shape, comprise a vertical edge and an arc-shaped side, its arc-shaped side periphery is provided with cutting teeth, the common cutting blade forming a circle after on the holder that two semicircular cutting blades are arranged on movable knife rack symmetrically.
2. grinder cutting blade as claimed in claim 1, is characterized in that: the vertical edge of the two semicircle cutting blades that the cutting blade of each circle is corresponding forms a continuous print circular arc external surface against, arc-shaped side mutually.
