Abstract
The utility model provides a tool for grinding cutting edges, which is composed of two sets of blades and shells of the blades. The structure of one set of blades is that the blades which are apart for a certain distance penetrate through a frame axis, the two sets of blades are installed on the corresponding interleave positions; a little free gap is left between the blade and the neighbor shim. The utility model with reasonable structure can grind quickly and grind ideal tool point.
Description
The utility model relates to a kind of sharpening instrument that grinds various single cutting edge of a knife or a sword cutter blades.
Grinding the most frequently used instrument of civilian cutter is whetstone or emery wheel, along with the miniature portable whetstone has appearred in the development of technology, resemble " the family expenses knife sharpener " of Chinese patent 90211452.2 in addition, its structure is to be provided with an emery wheel between two rollers, forms by the stage clip pressing at axle two ends; " the carbide alloy sharper " of the visible Chinese patent 89212823.2 of structure of another kind of knife sharpener is the overlapping fixedly composition of geometry two blade sections.These two kinds of blade grinding tools are the sharpening of realizing cutter by formed wedge-shaped slot in the structure substantially, the former mainly depends on the hard grind of sand grains to the cutter surface metal, the sand grains of wheel face falls to decreasing big on the one hand, shortened the service life of this grinding tool, the blade that mill is good is inhomogeneous on the other hand, can very fast rust.The latter's grinding tool is to rely on fixed blade to realize the sharpening of cutter, must make its attenuation to the metal that institute's knife milling tool applies the worn cutting edge of certain pressure both sides, and that pressure is gone into the wedge shape scope greatly is just narrow more, the edge of a knife grinds just thin more and friction at the bottom of knife edge place and the wedge-shaped slot is also big more, knife edge is impaired, therefore is difficult to obtain desirable knife edge.Above-mentioned several grinding tool frame mode is all not satisfactory.
Goal of the invention of the present utility model be to provide a kind of can the wear down cutting edge, can obtain the sharper of sharp knife edge again.
The sharper that the utility model provides, its major technique is characterised in that its structure is: be made up of two groups of blades, each set of blades is freely passed the frame axle by the cambered blade at a distance of certain intervals and is formed, each set of blades is inserted the blade interval of those set of blades, intersection is placed on the support and constitutes, and leaves a little free gap between blade and adjacent pads.
In technique scheme, the edge of a knife of two set of blades is located on the side of the same side.The number of blades optimum range of each group is at 2～4.
When utilizing sharper of the present utility model to grind cutter, not that the wedge shape grind reliefs that only intersects to form by two cambered blade groups is come grinding cutting edge both sides metal, also be owing to leave certain free gap between every group of blade and the pad at folk prescription during to the pulling cutter, two side blades apply one owing to pushing the cutting force that produces to institute's knife milling tool, cut its surface metal, and wedge shape stenosis cutter is cut very thinly, solved the contradiction of friction and the grinding of blade tool setting side between the knife edge that existing knife sharpener exists and the bottom land, because of its reaction produces a bigger cutting force, so grind more quick, the cutting edge quality height.Blade material adopts carbide alloy or high-carbon steel, and its life-span can extend greatly.
To describe the utility model in detail by following each accompanying drawing below:
Fig. 1 is the side shape assumption diagram of the utility model sharper
Fig. 2 is the A-A cutaway view of Fig. 1 sharper
Fig. 3, Fig. 4 are respectively the structural representation of hole frame and roof beam structure.
As shown in Figure 1, sharper of the present utility model includes roof beam structure 5, hole frame 6, frame axle 12.Blade 2.3 on 13 and the pad between each blade pull 4 and reach fixedly housing 1 composition of roof beam structure 5.
Cambered blade 2.3 is successively set on the frame axle 12.13 of roof beam structure 5 with pad 4, make blade 2.3 arranged in a crossed manner mutually, make and form a wedge-shaped slot 23 between it, then at the other end sleeve joint hole frame 6 of roof beam structure 5, respectively be provided with a baffle plate 15.16 on roof beam structure 5 and the hole frame 6, be used to limit the scope of activities of blade 2.3, promptly the free gap between blade 2.3 and the adjacent pads 4 is installed in its overall fixed on the housing 1 again.In the present embodiment, blade 2.3 is an annular.
When blade 2.3 was installed, its edge of a knife should be in the same side setting of blade.
The setting of multitool sheet can prevent the upper and lower drift of institute's knife milling tool knife edge line, guarantees the quality of sharpening, and the optimal number of every group of blade is 2～4.
Use for convenient, the handle that can help 10 is set on housing 1.
Claims (3)
1. sharper, it is made up of two groups of blades and its housing, it is characterized in that each set of blades is freely to pass frame axle (12.13) by the cambered blade (2.3) at a distance of certain intervals to constitute, the blade of each set of blades (2 or 3) inserts the blade interval of those set of blades (3 or 2), the staggered installation, blade (2.3) leaves a little free gap with adjacent pads (4).
2. sharper according to claim 1 is characterized in that being shaped on the edge of a knife at the same side of two set of blades.
3. sharper according to claim 1 and 2, the number of blades that it is characterized in that each set of blades is 2～4.
