The hard-cover of powder metallurgy refers to goods is placed in to former, by upper undershoot, goods is exerted pressure, and then sheds pressure, then deviates from from former, becomes the product that meets designing requirement.The existing widely used structure of finishing machine is: power source is a motor, through V-belt flywheel driven, rotate, flywheel drives eccentric crankshaft to rotate by gear mechanism, bent axle drives upper gliding mass to pump, and fixing of the forming frame is on middle template and upper gliding mass, and cope match-plate pattern is fixed on gliding mass, upper punch is fixed on upper punch fixed head, middle template is fixed on bed piece, and undershoot is fixed on undershoot fixed head, presses down adjusting screw(rod) and is arranged on lower bolster.Be generally by will needing finishing goods send into former and be positioned on plug manually, upper gliding mass drives cope match-plate pattern to move downward, and drive upper punch fixed head to move downward, to need finishing goods to be pressed into former, and drive undershoot to be pressed in to regulate the pressing down on adjusting screw(rod) of size, now go up gliding mass in extreme lower position, compressing.Along with upper gliding mass moves upward, start the demoulding, by undershoot cylinder and demoulding pull bar, drive undershoot to reset, and take goods out of former.Now go up gliding mass in extreme higher position, upper and lower mould is punched under the drive of mechanism and enters new round compacting, goes round and begins again.
Prior powder metallurgy goods finishing machine is by manually goods being put into former poor stability, ineffective problem.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide a kind of automation blowing and can realizes accurately and controlling, the finishing machine of a kind of turntable structure that operating efficiency is high and method of work thereof.
The technical solution used in the present invention is for this reason: the present invention includes rotating disk mechanism, rotating disk mechanism is provided with some stations, drives the transmission mechanism of rotating disk mechanism running, and the mould emptier of the briquetting machine that goods are suppressed, the goods demoulding;
Described rotating disk mechanism realizes by controlling organization and briquetting machine, mould emptier between effective cooperation; it meets the following conditions: a certain station in rotating disk mechanism rotates while entering briquetting machine; rotating disk mechanism stops operating; briquetting machine action; after compacting finishes, carry out the demoulding, after the demoulding finishes, rotating disk rotates again; when another station enters briquetting machine, repeat said process.
Described rotating disk mechanism comprises the dispenser (18) being connected in middle template (17), is fixed on the rotating disk (15) on dispenser (18), is fixed on the positioning sleeve (14) on rotating disk (15); Described dispenser (18) is driven by clutch by transmission mechanism.
Described clutch: comprise the dispenser axle (12) that drives dispenser (18), dispenser axle (12) drives running by clutch sprocket wheel (8), clutch slider (9), brake spring (10) by transmission mechanism.
Described transmission mechanism: comprise the flywheel by driven by motor, flywheel drives eccentric crankshaft by clutch, gear drive, eccentric crankshaft drives the output chain gear (1) being connected thereon to rotate, and drive elliptic gear (3) running by the gear-box sprocket wheel (2) of gear-box (4), elliptic gear (3) drives elliptic gear (5) running, and then driven gear case sprocket wheel (6) running, gear-box sprocket wheel (6) drives described clutch running.
Described controlling organization detects cylinder (19) after comprising the clutch sense switch (7) that is fixed in middle template (17), finishing; Before being fixed on the finishing on bottom plate of turntable (16), detect cylinder (21) and blanking cylinder (23), and the magnetic position switch coordinating with each cylinder is set, and the PLC of above each component movement is set.
Described rotating disk (15) is provided with 12 stations, and when 0-120 ° of output chain gear (1) motion, rotating disk (15) running makes a wherein station enter briquetting machine; At output chain gear, during in 120 °-360 °, rotating disk is in halted state.
After finishing is set in described middle template (17), detect air cylinder support (20), front air cylinder support (22) and the blanking air cylinder support (22) of detecting of finishing is set on bottom plate of turntable (16), each cylinder correspondence is arranged on corresponding air cylinder support.
A method of work for the finishing machine of turntable structure, according to following steps, carry out:
1) transmission mechanism drives rotating disk mechanism running, and when transmission mechanism operation enters the compacting scope of briquetting machine by a certain station of rotating disk mechanism, now transmission mechanism just drives briquetting machine to enter compacting state;
2) compacting: now clutch clutch shuts down rotating disk (15), and transmission mechanism drives briquetting machine running to realize the compacting to goods;
3) demoulding: after compacting finishes, rotating disk (15), still in halted state, enters the goods demoulding, and the demoulding finishes and drives goods to leave former;
4) after goods are deviate from, transmission mechanism moves one week briquetting machine is returned to after original position, and clutch connects, and drives rotating disk (15) running;
5) repeat 1)-4) step;
Wherein 2), 3) in step, be provided with detecting step.
Described detecting step: lathe is controlled by PLC is controlled and is detected cylinder (19), (21) move downward with blanking cylinder (21) when 120 °, lathe, enters to detect in station to detect:
Before finishing, detect cylinder (21), joining magnetic position opens the light, when detection cylinder (21) moves downward the middle goods height of positioning sleeve (14), regulate the magnetic position switch energising of position, rotary disc for indication location and goods position in positioning sleeve (14) are normal, by signal, to lathe PLC control system, lathe runs well; If positioning sleeve puts back without goods or goods in (14), detecting the energising of cylinder (21) magnetic position switch flashes across, PLC control system detects as no signal, it is separated immediately that PLC controls lathe clutch, the position deviation if rotating disk (15) calibration has not put in place, before finishing, detection cylinder (21) is failed to enter rotating disk positioning sleeve (14) magnetic position switch and be can't detect signal, and it is separated immediately that PLC controls lathe clutch;
After finishing, detect cylinder 19, join magnetic position switch, when detecting cylinder 19 and move in positioning sleeve goods height, regulate the magnetic position switch energising of position, indication has goods in positioning sleeve, by signal to lathe PLC control system, lathe runs well, if without goods, detect cylinder 19 magnetic position switches and can't detect signal in positioning sleeve, it is separated immediately that PLC controls lathe clutch;
Blanking cylinder 23, join magnetic position switch, when blanking cylinder 23 moved downward in positioning sleeve goods height, regulate the magnetic position switch energising of position, indication goods in positioning sleeve are discharged, by signal to lathe PLC control system, lathe runs well, if goods are not discharged in positioning sleeve, blanking cylinder 23 magnetic position switches can't detect signal, and it is separated immediately that PLC controls lathe clutch;
When during the demoulding, goods are stuck in former mouth, dispenser divides and does not turn, lathe operation, overload-release clutch medi-spring is pushed up back, clutch slide block is isolated clutch, and now clutch safety detection switch can't detect clutch slider signal, and it is separated immediately that PLC controls lathe clutch.
During rotating disk calibration, rotating disk first accelerates rear deceleration.
Advantage of the present invention is: 1) the present invention adopts rotating disk mechanism, by the cooperation of rotating disk mechanism and associated mechanisms, realizes self-feeding, compacting, the demoulding of goods, and it is compared its production efficiency of traditional mode and greatly improves, and it is more accurate;
