Description
Technical field
It the utility model is related to cutting tool technical field, more particularly to a kind of cutting movable bottom knife of single, double sword.
Background technology
It is a conventional process in manufacturing industry to cut processing, it is therefore an objective to which broad-width material is cut into the narrow material of needs.
Cutting mode is according to the difference using blade, the cutting of the side's of being divided into knife and dise knife cutting.Square knife cutting uses square blade, will run
In material it is longitudinally slit, be usually applicable only to soft and thin material.Dise knife cutting uses two circles of upper slitter and lower knife
Shape blade, both blade parallel contacts.During work, upper and lower knife rotates together, applies shearing and extruding to operating material
Effect, complete cutting.Dise knife cutting can process more hard material, and it is widely used in paper products processing, film, electric wire
The industries such as cable, rubber, aluminium foil, weaving, compound package material, printing.
And the incisory carving knife of electronic material, the required precision to bottom knife are higher, dashed forward existing for traditional bottom knife
It is that access times, service life are short to go wrong, and blade easily damages cutter shaft after cutting for a long time, and blade inner ring and blade outer shroud are again
The problem of concentricity deficiency during use be present；In addition, cutting edge end face run-out is big, material in cutting process is caused S types occur
Phenomenon.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of cutting movable bottom knife of single, double sword, sets
Multiple jackscrew fixed lower blades, avoid the occurrence of indivedual jackscrew stripped threads cause blade can not normal use, flexible modulation, user
Just；The mounting elastic sheet in shell fragment groove, effectively protect cutter shaft injury-free, greatly improve the precision of blade, it is ensured that right angle cuts, prevent
Only there is S-shaped cutting, precision is high, does not offset；The design of double blade can be effectively increased the access times of blade, and extension uses the longevity
Life, it is cost-effective.
To achieve the above object, the utility model uses following technical proposals：
One kind the cutting movable bottom knife of single, double sword, including blade outer shroud, blade inner ring, cutting edge and jackscrew, the knife
The outside of piece outer shroud sets one or two described cutting edge, and basil α is 80 ° -90 °, and what the jackscrew ran through is opened in described
In blade outer shroud and the blade inner ring, the jackscrew quantity is 1-4, and annular is further opened with along on the inside of the blade inner ring
Shell fragment groove, the shell fragment of bending is installed in the shell fragment groove.
The technical solution of the utility model also includes, and the jackscrew quantity is 2, and jackscrew is fixed in screw, played
The effect of fixed lower blade, moreover it is possible to prevent jackscrew occur stripped thread cause blade can not normal use, flexible modulation is easy to use.
The technical solution of the utility model also includes, and the outside of the blade outer shroud sets a cutting edge, is single-blade
Structure, basil α are 85 °.
The technical solution of the utility model also includes, and the outside of the blade outer shroud sets two cutting edges, is twolip
Structure, the basil are 85 °, and the design of double blade can be effectively increased the access times of blade, increase the service life, cost-effective.
The technical solution of the utility model also includes, and the shell fragment groove is adapted with the shell fragment, and size is adjustable, shell fragment
Play and protect cutter shaft not damaged by jackscrew, increase the concentricity and precision of blade.
The beneficial effects of the utility model are to set multiple jackscrew fixed lower blades, avoid the occurrence of stripped thread cause blade without
Method normal use, flexible modulation are easy to use；The mounting elastic sheet in shell fragment groove, effectively protect cutter shaft not damage, greatly improve
The precision of blade, it is ensured that right angle cuts, prevent S-shaped cutting, precision is high, does not offset；The design of double blade can be effectively increased
The access times of blade, increase the service life, cost-effective.
