Abstract
The utility model relates to a movable figure eight cutter, which is applied to a plastic crusher. The utility model is characterized in that a cutting edge of the cutter is formed into a symmetrical figure eight shape, and an included angle which is formed between both ends of the cutter and the side surface of a cutter body is from 70 DEG to 85 DEG. A rear sectional surface of the cutting edge is formed into a convex arc surface. An included angle which is formed between both ends of an edge cutting rake angle surface and a front extension surface of a bottom surface of the cutter body is from 35 DEG to 45 DEG. The bottom surface of the cutter body is provided with a positioning groove. Two to four cutters are arranged and fixed on a cutter wheel of the crusher to cut materials gradually. The utility model has the advantages of the stress of the cutting edge is reduced, the service life of the utility model is from eight to ten times as mount as the existing product, the installation and the maintenance are convenient, the cutter can be ground many times, and the production cost is reduced.
Description
The utility model relates to a kind of parts of crushing mechanism, particularly a kind of movable Eight characters cutter that is used on the plastic breaker.
The traditional type plastic breaker all is to use flat blade, and suffered resistance is big during cutting, and the impulsive force of moment makes the blade breach easily, and service life is short.Occurred a kind of herringbone cutter of five row's one in recent years, though performance increases, it is an integral body, as long as a slice is damaged, then whole cutter hub is scrapped, and can only disposablely use the production cost height.
The purpose of this utility model is in order to overcome above-mentioned weak point, and a kind of long service life is provided, and installation and maintenance are convenient, the movable Eight characters cutter that reduces production costs.
The purpose of this utility model is achieved in that the blade of movable Eight characters cutter is the splayed of symmetry, the angle of two ends and cutter hub side is 70 °-85 °, tangent plane is the convex face behind the blade, constitute by 2-3 lower inclined plane above the cutter hub or be the convex face, before sword is cut before edged surface two ends and the cutter hub bottom surface angle of extended surface be 35 °-45 °, the cutter hub bottom surface has locating slot, has above the cutter hub of corresponding locating slot and installs and fixes the hole.
Fig. 1 is the utility model planform figure;
Fig. 2 is the utility model front view.
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
The blade 1 of movable Eight characters cutter is the splayed of symmetry, the angle of two ends and cutter hub side 2 is 80 °, tangent plane 3 is the convex face behind the blade, 4 are made of three following dry measure used in former times faces above the cutter hub, the angle of edged surface 5 two ends and cutter hub bottom surface 6 preceding extended surfaces was 40 ° before sword was cut, cutter hub bottom surface 6 has locating slot 7, and 4 have three and install and fix hole 8 above the cutter hub of corresponding locating slot 7.
The utility model is fixed on this movable Eight characters cutter of 2-4 sheet on the disintegrating machine break bar owing to adopt above design, and material is sheared gradually, reduced the stressed of blade, be 8-10 times of existing product service life, and installation and maintenance are convenient, repeatedly reconditioning, thus production cost reduced.
