Description
Technical field
A kind of sheet metal blanking units of the present invention relates to a kind of device for die-cut sheet metal, can be widely used in the die-cut and moulding of metal material.
Background technology
Punch press, as cold working machinery, is widely used in the die-cut and moulding of metal material, is most of makers' common equipments.
The main part of punch press is its punching press power source, and the power source of extensive use now has two kinds of forms: a kind of is the mechanical type that adopts toggle; Another kind is hydraulic driven.Mechanical type is to do gyration by driven by motor crank axle, and crank drivening rod and slide block do upper and lower rectilinear motion and complete punching press action; Fluid pressure type adopts hydraulic oil pump to produce pressure oil, and by oil pipe, magnetic valve is controlled hydraulic cylinder piston rod motion, completes various punching press actions.
Owing to adopting toggle, there is at the volley dead point in mechanical punch, must assembling flywheel, therefore can cause that punch press is bulky, the motion noise of inefficiency and generation is large.It is pressure oil that the power of fluid pressure type produces medium, in pipeline, can produce very high pressure, adds that hydraulic oil constantly moves back and forth, and is easy to cause the leakage of hydraulic oil, affects the normal use of punch press.Particularly in electric mechanical industry, high to the punching precision of lathe, meet the actual market demand so be necessary to design a kind of new die-cut machinery.
Summary of the invention
The object of the invention is for above-mentioned weak point, and a kind of sheet metal blanking units is provided, and has accurately controlled, simple in structure, easy to operate feature of die-cut amount, is applicable to the free of contamination operating environment of mechano-electronic generic request.
A kind of sheet metal blanking units takes following technical scheme to realize: a kind of sheet metal blanking units comprises servomotor, reductor, electrical machine belt pulley, cog belt, screw mandrel belt wheel, the rotary ball screw of accurate nut, mould mounting base, guide pillar, guide pin bushing, connecting plate, intermediate plate, diel, cope match-plate pattern, upper limit position switch, back to zero bit switch and lower position switch; Wherein the rotary ball screw of accurate nut is made up of feed screw nut, combination bearing and screw mandrel, and screw mandrel is arranged in feed screw nut by the screw thread on shaft, and combination bearing and screw mandrel belt wheel are installed on feed screw nut.
Below mould mounting base, be provided with mounting seat.
Reductor top is provided with electrical machine belt pulley, and reductor below connects servomotor by power transmission shaft, and reductor is fixed by bolts in mounting seat by flange, then is arranged on mould mounting base;
Screw mandrel belt wheel is fixed on the feed screw nut of the rotary screw mandrel of accurate nut, the outer ring of the upper combination bearing of feed screw nut is fixed by bolts in mounting seat by flange, mounting seat and mould mounting base are fixed with bolt, then electrical machine belt pulley are connected with screw mandrel belt wheel with cog belt; Four guide pillars are vertically mounted on mould mounting base, have a guide pin bushing on every guide pillar, and intermediate plate is enclosed within on guide pin bushing and fixes, and intermediate plate follows guide pillar to move up and down in the time that guide pillar moves; Cope match-plate pattern is positioned at the top of guide pillar, and cope match-plate pattern is fixed into entirety by four guide pillars and mould mounting base; The below of intermediate plate is installed with connecting plate, is installed with screw mandrel on connecting plate.
Upper die and lower die are installed in diel, counterdie in diel is connected with intermediate plate, patrix and cope match-plate pattern in diel are fixed, on being disposed with from top to bottom on the limit of guide pillar, be limited to switch, back to zero bit switch and lower position switch, the effect of upper limit position switch, back to zero bit switch and lower position switch is to guarantee that stamping die prodigiosin moves in certain scope.
Operation principle
A kind of sheet metal blanking units is fixedly mounted on mould installing floor board in frame while use, in the time of work, servomotor is slowed down the power source of the large torsion of the slow-speed of revolution is input on the rotating nut of the rotary ball screw of accurate nut by reductor and belt wheel, feed screw nut changes into again the rectilinear movement up and down of screw mandrel by rotatablely moving, because the pitch of screw mandrel is less, so the thrust that screw mandrel produces is very large, just can drive diel to carry out effectively die-cut; Whole device is owing to having used SERVO CONTROL, and driving-chain precision is very high, and the complete like this die-cut amount that can accurately control shell fragment, reaches desirable die-cut effect.
Utilize this blanking units, calculate blanking pressure the die-cut effect to shell fragment is described;
1. the thrust that screw mandrel end produces: F=2* п * M* η/P
The thrust (N of unit) that note: F is screw mandrel, moment of torsion (NM of unit), the P that M produces for power source are that screw lead (mm of unit), η are mechanical efficiency (getting 0.9)
2. the specified torsion T=2.39NM of known servomotor, rated speed 3000 turns.Reductor speed reducing ratio is λ 1=6, the speed reducing ratio λ 2=2 of belt wheel.Screw lead is 10mm.
M=T*λ1*λ2
=2.39*6*2
=28.68(NM)
3. according to above-mentioned known: screw mandrel thrust
F=2*п*M*η/P
=2*3.14*28.68*0.9*1000/10
1.62 tons of=16210 (N) ≈
4. the shell fragment thickness range using in current electronics industry is t=0.1 ∽ 0.3mm, adopts flat blade cutter mouth die-cut, and die-cut shapes is roughly following two kinds, square or circular.Shell fragment material is steel, and the shearing strength of its material is about T=44 ∽ 60(Kg/mm2)
By material cutting power formula: P=t*L*T
Wherein: t is that shell fragment thickness (mm), L are that die-cut material girth (mm), P are blanking pressure (kg), in figure below, L=2* (A+B) or L=п * D.What the hypothesis material of cutting was 20mm now is square, and thickness is 0.2mm.By upper formula:
P=t*L*T=0.2*2*(20+20) * 55=880(kg)=0.88 ton
5. as can be seen here, the screw mandrel thrust F=1.62 ton that this device produces is far longer than the blanking pressure P=0.88 ton of shell fragment, can effectively carry out stamping-out.
In the present invention, servomotor and reductor drive ball screw nut rotation by odontoid belt, and ball screw is moved up and down, thereby drive punch die to do die-cut motion; The die-cut amount of this blanking units is accurately controlled, simple in structure, is applicable to operation under the free of contamination environment of mechanical electric subclass.
