Description
Technical field
A kind of sheet metal of the present invention blanking units relates to a kind of device for die-cut sheet metal, can be widely used in the die-cut and shaping of metal material.
Background technology
Punch press is as cold working machinery, and being widely used in the die-cut and shaping 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 present extensive use has two kinds of forms: a kind of is the mechanical type adopting toggle; Another kind is hydraulic driven.Mechanical type does gyration by driven by motor crank axle, and crank handle turns connecting 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 carrys out the motion of hydraulic control cylinder piston rod, completes various punching press action.
Owing to adopting toggle, there is dead point at the volley, must assemble flywheel in mechanical punch, 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, can produce very high pressure, add that hydraulic oil constantly moves back and forth, be easy to the leakage causing hydraulic oil, affect the normal use of punch press in pipeline.Particularly in electric mechanical industry, high to the punching precision of lathe, so be necessary that designing a kind of die-cut machinery newly meets the actual market demand.
Summary of the invention
The object of the invention is: for above-mentioned weak point, provides a kind of sheet metal blanking units, has the advantages that die-cut amount controllable precise, structure are simple, easy to operate, 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, feed screw nut is provided with combination bearing and screw mandrel belt wheel.
The below of mould mounting base is provided with mounting seat.
Be provided with electrical machine belt pulley above reductor, connect servomotor below reductor by power transmission shaft, 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 bolt are fixed, then are connected with screw mandrel belt wheel by electrical machine belt pulley with cog belt; Four guide pillars are vertically mounted on mould mounting base, every root guide pillar have a guide pin bushing, and intermediate plate is enclosed within guide pin bushing also fixing, and intermediate plate moves up and down with guide pillar when 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, and connecting plate is installed with screw mandrel.
Diel is provided with upper die and lower die, counterdie in diel is connected with intermediate plate, patrix in diel and cope match-plate pattern are fixed, the limit of guide pillar is disposed with upper limit position switch, back to zero bit switch and lower position switch from top to bottom, and the effect of upper limit position switch, back to zero bit switch and lower position switch ensures that stamping die prodigiosin moves in certain scope.
Operation principle
Mould installing floor board is fixedly mounted in frame when using by a kind of sheet metal blanking units, operationally, servomotor is slowed down by reductor and belt wheel and is input on the rotating nut of the rotary ball screw of accurate nut by the power source of large for slow-speed of revolution torsion, convert rotational motion is become again the rectilinear movement up and down of screw mandrel by feed screw nut, because the pitch of screw mandrel is less, so the thrust that screw mandrel produces is very large, diel just can be driven to carry out effectively die-cut; Whole device is owing to employing SERVO CONTROL, and driving-chain precision is very high, and the complete so die-cut amount that accurately can control shell fragment, reaches desirable die-cut effect.
Utilize this blanking units, calculating blanking pressure illustrates the die-cut effect to shell fragment;
1. the thrust that produces of screw mandrel end: F=2* п * M* η/P
The moment of torsion (unit NM) that the thrust (unit N) that note: F is screw mandrel, M produce for power source, P are screw lead (unit mm), η is 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
=16210 (N) ≈ 1.62 tons
4. the shell fragment thickness range current electronics industry used is t=0.1 ~ 0.3mm, and adopt flat blade cutter mouth die-cut, 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/mm
2)
By material cutting power formula: P=t*L*T
Wherein: t is shell fragment thickness (mm), L is die-cut material girth (mm), P is blanking pressure (kg), in figure below, L=2* (A+B) or L=п * D.Present hypothesis to cut material be the square of 20mm, 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, effectively can carry out stamping-out.
In the present invention, servomotor and reductor drive ball screw nut to rotate by odontoid belt, and ball screw is moved up and down, thus drive punch die to do blanking movement; The die-cut amount controllable precise of this blanking units, structure are simple, operation under the applicable free of contamination environment of mechanical electric subclass.
