A kind of circular arc knife grinder and its frock clamp
Technical field
The utility model belongs to tool lapping apparatus field, specifically, is related to a kind of circular arc knife grinder and its frock
Fixture.
Background technology
The grinding of cutter is generally divided into hand-ground and mechanical lapping, and the advantage of hand-ground is grinding precision high, knife
Have sharp attractive in appearance, but grinding efficiency is low, and hand labor intensity is big;Mechanical lapping is limited by the shape of tool, grinding not enough essence
Carefully, but mechanical lapping use automatic grinding equipment, it is not necessary to manpower participate in, it is only necessary to control various parameters, you can make equipment
It is automatically performed, grinding efficiency is very high, so extensive in cutter manufacture sector application.
Circular arc knife refers to circular knives of the cutting edge in circular arc, is used for circular and circle indenture processing, in engraving tradition flower
Also there is very big use on grass, such as dry disc of floral leaf, petal and spray is all needed with the conformal treatment of dise knife.Circular arc knife laterally transports knife ratio
It is relatively labor-saving, big fluctuating, small change can be adapted to.According to different purposes, the model of circular arc knife should be differentiated, size
Scope is basic between 5 centimetres -0.5 centimetre.Two jiaos of the edge of a knife for being circular engravure personage will grind off, in circular arc, otherwise carve clothing line or
During other indentures, not only push away motionless, can also make the both sides in indenture road damaged.If do embossment, then should retain two jiaos of the edge of a knife, and
Corner is carved using the function of its top of the horn.Because dise knife purposes is different, corresponding edge of a knife shape is also different, so correspondence is different
Circular arc knife should use different milling apparatus.As shown in figure 1, a kind of special-shaped circular arc knife, harvest circular arc in its edge of a knife, and be half
Round shape, common grinding machine is difficult to realize the processing of this circular arc knife, it is therefore desirable to design a kind of special equipment.
Chinese Patent Application No. 201420441494.2, the publication date patent document on December 31 in 2014, discloses one
