Description
Technical field
The utility model relates to and to be used in shredder for pulverizing the blade configurations field of paper, especially relates to a kind of light and thin type kneader bar.
Background technology
In prior art, a tool setting rod is provided with in shredder, the barred body interval string of cutter rod is provided with some blade for shredding paper groups, blade for shredding paper group is close together back-to-back by two blade for shredding paper and its point of a knife is overlapping, the interlaced occlusion of blade for shredding paper group on two cutter rods, the staggered shearing of two blade for shredding paper groups that namely set of blades of a cutter rod is adjacent with another cutter rod coordinates.
The blade for shredding paper be widely used at present in shredder is distinguished by its cutter hub thickness and is mainly contained two kinds, and one is traditional thick blade, and one is light and thin type blade.Compared with traditional thick blade, light and thin type blade is lightweight, and reduce materials'use amount, cost is lower.Meanwhile, also there is obvious shortcoming in light and thin type blade, and the structural strength of light and thin type blade entirety also decreases, and especially the structural strength of the point of a knife of light and thin type blade and the structural strength of point of a knife and cutter hub junction all obviously decline.
For solving this technical problem, solution main is at present: in the punch forming process of light and thin type blade, a small amount of material is reserved at the side of its point of a knife, again by point of a knife punch forming or the extruded point of a knife for having twice cutter hub thickness, in the punch forming process of light and thin type blade, its forming step is more, need very complicated and accurate diel, very high to the required precision of diel, therefore, in volume production process, its Forming Quality is very unstable, and yields is not high.The second, being limited by the structural design of light and thin type blade and point of a knife thereof, cutter hub outer rim is except a small amount of material of point of a knife and point of a knife side, the material of cutter hub outer rim other parts directly cuts as waste material, waste material is more, and it is not high to be used for the utilization rate of band of shaping blades, wastes more.3rd, the structural strength of point of a knife is still not high, and the structural strength of point of a knife and cutter hub junction is not high yet, is therefore necessary to be improved.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of light and thin type kneader bar, and its forming step is few, is easy to produce, and reduces the required precision to diel, and in volume production process, Forming Quality is stablized, and yields is high.
For the deficiency that prior art exists, another object of the present utility model is to provide a kind of light and thin type kneader bar, needs the waste material that cuts less in punch forming process, and it is high to be used for the utilization rate of band of shaping blades, cuts the waste, reduces costs further.
For the deficiency that prior art exists, another object of the present utility model is to provide a kind of light and thin type kneader bar, and the structural strength that it improves point of a knife is high, improves the structural strength of point of a knife and cutter hub junction simultaneously.
To achieve these goals, the technical scheme that the utility model adopts is.
A kind of light and thin type kneader bar, comprise cutter hub, installing hole is offered in the middle part of cutter hub, for being gone here and there the cutter rod being located at shredder, the outer rim of cutter hub is provided with at least two points of a knife, and the back of point of a knife offers a fracture, the sheet material of cutter hub outer rim is to side turnover formation one wall body, wall body on front side of the cutter hub of incision position and fracture forms the point of a knife of integrative-structure, and along the direction of rotation of kneader bar, the blade of wall body on front side of a point of a knife or tip extend to the incision position of next point of a knife.
In further technical scheme, in the outer rim of cutter hub, the sheet material of the point of a knife both sides sheet material to side turnover and on front side of point of a knife forms the point of a knife of described protrusion in cutter hub outer rim to depression one curved portions to inward side.
In further technical scheme, described wall body forms the side between two points of a knife of cutter hub outer rim, and the thickness of wall body equals the package thickness of a kneader bar.
In further technical scheme, described wall body is perpendicular to cutter hub.
In further technical scheme, the wall body exceeding cutter hub surface disconnects at incision position, and the cutter hub below fracture forms the back of point of a knife.
In further technical scheme, the wall body exceeding cutter hub surface disconnects at incision position, and the wall body on rear side of fracture and the cutter hub below fracture form the back of point of a knife.
In further technical scheme, exceed the thickness of thickness equal or close to cutter hub of the wall body on cutter hub surface.
In further technical scheme, the hole wall of described installing hole extends a spacer ring to side.
Adopt after said structure, the utility model compared to the prior art advantageously:
The first, the utility model forming step is few, is easy to produce, and reduces the required precision to diel, and in volume production process, Forming Quality is stablized, and yields is high.
Second, because the abapical material of cutter hub outer rim cutter all uses by the utility model, both the structural strength of blade and point of a knife had been added, be increased in the cutting performance in shredded paper process and shredded paper ability, reduce again band in punch forming process, need the waste material that cuts, waste material is less, and it is higher to be used for the utilization rate of band of shaping blades, cut the waste, reduce costs further.
3rd, the structural strength that the utility model improves point of a knife is high, improves the structural strength of point of a knife and cutter hub junction simultaneously.
4th, outer cause some sections of wall bodies of cutter hub are surrounded, and increase the structural strength of blade and cutter hub entirety.
