2. Denne maskine vedtager jog, enkelt og kontinuerlig arbejdskonvertering med god automatisering, bekvem betjening og høj produktionseffektivitet.
2. Overordnet struktur og arbejdsprincip
1. Overordnet struktur Maskinen er hovedsageligt sammensat af mekanisk system (hovedenhedsdel), elektrisk system, hydraulisk system osv.
(1) Hovedmotoren er hovedsageligt sammensat af en hovedpressemekanisme og en skubbemekanisme.
1. Hovedpressemekanismen er sammensat af øvre bjælke, nederste bjælke, opretstående søjle og materialepressecylinder. Den øvre bjælke, nederste bjælke og mellembjælke er alle svejsede konstruktionsdele. Den øvre og nedre bjælke er sammensat af opretstående søjler, opretstående hætter og opretstående møtrikker for at danne hovedrammen på mainframe. Trykoliecylinderen er en frontflangestruktur og er fastgjort på den øvre bjælke. Stempelstangen til den materielle oliecylinder er forbundet med den øvre matrice ved hjælp af indvendige gevind, og den øvre matrice drives af oliecylinderen for at bevæge sig op og ned lineært. Trykoliecylinderen er en kombineret oliecylinder, der er sammensat af en enkeltvirkende hovedtryksoliecylinder af stempeltype og en hurtig arbejdsoliecylinder. Den hurtige indarbejdede oliecylinder er en dobbeltvirkende oliecylinder med stempeltype med stempler, styremuffer osv. Og en tætningsring. Nederste bjælke fungerer også som en arbejdsplatform udstyret med hjælpeforme og skubcylindre.
2. The pushing mechanism is composed of a pushing cylinder and auxiliary molds. The pushing cylinder is a piston type double-acting cylinder, which is fixed on the lower beam of the main machine with a front flange structure, and the front end is connected with the ejection pad of the auxiliary mold. The auxiliary mold is composed of an upper mold, a lower fixed mold base, a mold release pad, an inner mold sleeve, a lower mold pressing plate, and a feeding hopper. The upper mold is connected to the material pressing oil cylinder with external threads and the piston rod uses the material pressing oil cylinder to move up and down to compact the material in the inner mold sleeve. The lower fixed mold base is fixed on the lower beam with screws, and a surface-treated wear-resistant inner mold sleeve and die pad are installed in the middle, and the inner mold sleeve is fixed in the lower fixed mold base with a molding plate (see the attached mold structure diagram).
3. The hydraulic oil cylinder is composed of a material pressing oil cylinder and a material pushing oil cylinder. The pressure oil cylinder is composed of a main pressure oil cylinder and a quick work feed oil cylinder. The main pressure oil cylinder is a piston single-acting oil cylinder and also adopts a piston structure. Except for the front cavity without oil, the structure is the same as the fast work feed oil cylinder and the push oil cylinder Consistent. The quick-working oil inlet cylinder and the pushing oil cylinder are both piston-type double-acting oil cylinders. The piston is equipped with a sealing ring to form two oil chambers in the cylinder. When the high pressure oil acts on the rear cavity (also known as the large cavity) or the front cavity (Also known as small cavity) when pushing the piston to make a straight reciprocating motion in the cylinder, to achieve the purpose of driving the moving parts. At the same time, the cylinder port is provided with a guide sleeve for supporting, guiding and sealing the piston rod.
(2) Det elektriske system består af to dele: et motorstyringskredsløb og et handlingskontrolkredsløb.
(3) Det hydrauliske system er sammensat af olietank, pumpestation, ventilstation osv. Hovedmotoren er opdelt i to dele: tilførselsoliekredsløbet og hovedtryksoliekredsløbet.
2. Working principle
Tilsæt det materiale, der skal behandles, fra beholderen til den nederste formstøbning, tryk på den automatiske knap, den øverste form komprimerer materialet ned til systemets indstillede tryk og vender tilbage i 1 til 2 sekunder (indstillet af plc) for at aflæsse, og skubcylinderen vender tilbage Når den er på plads, bevæger den øvre form sig nedad for at ekstrudere metalchipsene i den indre formhylster ud af formhulrummet og vender tilbage, og skubcylinderen bevæger sig fremad for at skubbe komprimatoren ud af formhulrummet og fuldføre en arbejdscyklus.
Four, electrical system
(1) Overview It is powered by a 380 volt AC power supply and consists of two parts: the main circuit and the control circuit.
1. Hovedkredsløbet består af to dele: motorkredsløbet og nødstopkredsløbet, der får strøm fra en 380V strømforsyning. Motorkredsløbet leverer direkte strøm til en trefaset asynkronmotor af y-typen fra kredsløbets strømforsyning til at drive en stempelpumpe og en tandhjulspumpe. Nødstopkredsløbet består af en nødstopknap og mellemrelæ. I tilfælde af en ulykke skal du blot trykke på nødstopknappen for at stoppe motoren og afbryde alle handlinger.
2. The control circuit is composed of two parts: a motor control loop and an action control loop (also called plc input and output loop). The motor control circuit is composed of motor start, stop and motor work display, etc. The action control circuit is composed of the forward and backward movements of the main pressure cylinder and the forward and backward movements of the pushing cylinder, which are mainly used to control the mechanical work.
