Description
Technical field
The invention belongs to grinder technical field, more particularly, it relates to a kind of cutting disc computer controlled grinding machine and grinding thereof
Method.
Background technology
Cutting disc is one of vitals of cutting machine equipment.It is usually according to cutting difference coming of material category and thickness
Determine to select which kind of slitter blade.Generally form of the cutting side of the including cutter of slitter blade is cut and is cut with dise knife.Side's cutter divides
Cutting is exactly as razor, is fixed on the knife rest of cutting machine by blade, is fallen by cutter in material running, makes cutter by material
Expect longitudinally slit, to reach to cut purpose.Dise knife is cut mainly has the shearing of upper and lower cutting disc and dise knife squash type to cut two kinds of sides
Formula.Dise knife cuts the mode of mainly cutting being to cut the materials such as thick film, composite thick film, paper.Cut material membrane material thickness 100
μm selection suggested by the above dise knife is cut.Dise knife squash type cuts mode both can cut the relatively thin plastic sheeting of ratio, it is also possible to point
Cut the thick paper of comparison, non-woven fabrics etc., be that one cuts mode eaily.
In cutting industry, the machining accuracy of cutting disc and efficiency always affect the restraining factors of industry development, especially
It is that the processing of the cutting disc edge of a knife is always technological difficulties, because the thinner thickness of blade own, in addition it is also necessary to the cutter that grinding tilts
Blade surface, the requirement to processing is the highest, a kind of cutting disc as shown in Figures 1 and 2, and its main body is circular, and thickness is left at 3mm
The right side, needs to process two inclined planes at the edge of its one side, is cutting face a and blade face b, cutting face a and blade face respectively
Become small angle α, blade face b to become angle β with blade face, and β is more than α.These type of blade great majority of existing processing use
Manual grinding or semi-automatic controlling machine grinding, manual grinding wastes time and energy, and production efficiency is low, and precision is relatively low；Semi-automatic
Although lathe grinding grinding accuracy is higher, but operation requires higher, is difficult to grasp, and percent defective is higher, and investment is higher.
It is directed to the problems referred to above, there has been proposed improvement project at present, as Chinese Patent Application No. is:
201310059700.3, publication date is: the patent documentation on May 8th, 2013, disclose a kind of Numerical control precise circular knife grinder and
Its method.This grinder include support, X-axis guiderail base, X-axis guide rail, X-axis slide block, X-axis slide plate, X-axis servomotor cabinet,
Emery wheel clamp nut, emery wheel, work piece nut, workpiece fixed disc, workpiece, Z axis servomotor cabinet, input keyboard, meter
At the bottom of calculation machine, guidance panel, casing, Z axis feed servo motor, Z axis slide block, swivel base, Z axis slide plate, Z axis guide rail, Z axis guide rail
Seat, X-axis feed servo motor, X-axis shaft coupling, rotary slider, Z axis shaft coupling, Z axis feed servo motor.The program can be used
Carry out the grinding of dise knife, and be improved in terms of precision and efficiency, but its letter after multipotency is suitable for blade abrasion
Single reconditioning, it also illustrate that in its application documents the as noted above cutting disc of ratio uses this device processing cutting face a also
Have certainly possible, and be in the case of the adjustment manually carrying out a little meets cutting face a angle requirement, machining accuracy and
Surface quality is the lowest, and blade face b cannot process, and can go out tipping, process the situations such as uneven, and the blade of processing also cannot make
With, so high accuracy when it can not meet blade production and processing, high-quality requirement at all, need to be further improved.
And for example, Chinese Patent Application No. is: 201420441494.2, and publication date is: in December, 2014 patent of 31 days literary composition
Offer, disclose a kind of bull dise knife edge of a knife computer controlled grinding machine, include support, support is provided with three Y-axis slide units, before slide unit
End one_to_one corresponding is provided with A spindle turntable that central shaft is vertically arranged, B spindle turntable, C spindle turntable, on each carriage saddle point
Not equipped with respective Z axis slide unit, respective slide unit equipped with grinding wheel stand, on three grinding wheel stands one_to_one corresponding be rotatablely equipped with A main shaft emery wheel,
B main shaft emery wheel, C main shaft emery wheel.Equipped with Y1, Y2, Y3 axle in frame, Y-axis slide unit is by servo motor transmission ball screw, in drive
Slide does round action.Upper saddle, equipped with Z axis servo motor transmission ball screw, drives Z axis slide block to make cutter of retreating up and down.W axle
The automatic equipment of the step motor control anglec of rotation.The program can only the surface of grinding blade, if processing blade, need by spy
The grinding wheel shape of different shape, the blade angle of the corresponding a kind of blade of a kind of emery wheel, also can only simply process an inclined-plane, and operation
Loaded down with trivial details, machining accuracy is poor, and efficiency is low.
In summary, there is presently no and high accuracy can process cutting disc blade with high efficiency, especially complicated blade
Milling apparatus, seriously the development of industry is cut in restriction, and the bottleneck how breaking cutting disc grinding is that people are devoted to always
The problem solved.
