[0055] The specific application of the second embodiment is as follows: after the metal alloy powder is pressed and molded, as the pressing and molding process is finished, the pressing column 602 of the device is located inside the molding groove 303 (at this time, the pressing column 602 after the pressing and molding is located inside the molding groove 303, and there is a distance from the outer top of the molding groove 303, and this distance is the pressing space for pressing and molding, which ensures that the entire alloy metal powder can be fully pressed to ensure the integrity of the molded alloy rod-shaped metal); When it is necessary to demold the formed alloy rod-shaped metal, when the pressed column 602 completes the final pressing action, the L-shaped extrusion plate 611 fixed to the side of the second connecting flange 601 and the pressing plate 612 fixed to the top of the L-shaped extrusion plate 611 will gradually approach the first control button 320 fixed to the bottom of the vertical rod 319, and thereby generate pressure on the first control button 320, driving the first control button 320 to start, and at this time, the electromagnet 510 electrically connected to the first control button 320 starts to energize and generate magnetism, and thereby generates a magnetic adsorption force on the plug-in iron block 610, driving the plug-in iron block 610 to instantly approach the inside of the rectangular displacement frame 520 fixed to one side of the U-shaped lifting plate 507, thereby completing the insertion. The connecting iron block 610 is engaged with the rectangular displacement frame 520. After the engagement is completed, the second connecting flange 601 fixed to the telescopic end of the telescopic cylinder 308 and the pressing column 602 fixed to the bottom of the second connecting flange 601 move upward synchronously. When the pressing column 602 moves upward synchronously, it will synchronously drive the U-shaped lifting plate 507 fixed between the two first lifting plates 505 to slide upward between the two limiting round rods 322, and thereby stretch the fourth spring 506 fixedly connected between the first lifting plate 505 and the forming table 301. Later, as the U-shaped lifting plate 507 slides upward between the two limiting round rods 322, it drives the third lever 509 respectively fixed on the two opposite sides of the first inclined plate 508 to synchronously move in the H-shaped The rotating plate 511 slides inside the two third sliding grooves 513 respectively penetrated by the two side surfaces, and thereby drives the rotating hole 512 penetrated by one side of the H-shaped rotating plate 511 to pull up and rotate on the peripheral side surface of the rotating shaft 317, so that the fourth lever 515 slidingly matched with the inner walls of the two fourth sliding grooves 514 respectively presses down and slides synchronously, driving the L-shaped inclined plate 516 fixed between the two fourth levers 515 and the I-shaped sliding block 517 fixed on one side of the L-shaped inclined plate 516 to slide downward between the two U-shaped vertical plates 315 synchronously. When the L-shaped inclined plate 516 fixed between the two fourth levers 515 and the I-shaped sliding block 517 fixed on one side of the L-shaped inclined plate 516 slide downward between the two U-shaped vertical plates 315 synchronously, the I-shaped sliding block 517 The L-shaped lifting plate 518 fixed on one side and the fifth lever 519 fixed on the two sides of the L-shaped lifting plate 518 are synchronously pressed down and slid inside the second slide groove 504, driving the V-shaped rocker plate 501 in the linkage 5 that rotates and cooperates with the hinge seat 314 to synchronously press down and hinge and rotate, thereby driving the second lever 502 fixed on the two sides of the V-shaped rocker plate 501 to slide synchronously inside the two first slide grooves 405, and thereby providing a force for the upward sliding of the U-shaped plate 404, driving the sample stripping rod 401 fixed on the outer top of the U-shaped plate 404 to move upward inside the smooth hole 311, thereby compressing the third spring 406 fixedly connected between the outer top of the U-shaped plate 404 and the inner top of the built-in groove 312.The ejection plate 402 fixed on the top of the stripping rod 401 inside the forming groove 303 moves upward synchronously, so that the pressed alloy rod-shaped metal is subjected to a synchronous ejection process after being pressed through the contraction process of the telescopic cylinder 308. After the ejection process is completed, the ejected and pressed alloy rod-shaped metal is grasped and placed in another position in combination with a mechanical arm for subsequent operation (the mechanical arm is a prior art, which is not drawn here and will not be elaborated on in detail). The whole process does not require the addition of an additional power source to perform ejection and demolding operations on the formed alloy rod-shaped metal, which can save energy and improve the working efficiency of the entire pressing and forming process; After the above-mentioned formed alloy rod-shaped metal is ejected, the telescopic cylinder 308 continues to contract, driving the L-shaped extrusion plate 611 fixed on the side surface of the second connecting flange 601 and the pressure plate 612 fixed on the top of the L-shaped extrusion plate 611 to gradually approach the second control button 321, thereby generating pressure on the second control button 321, so that the second control button 321 starts to start. At this time, the electromagnet 510 electrically connected to the second control button 321 begins to be powered off and demagnetized, so that the magnetic adsorption force of the electromagnet 510 on the plug-in iron block 610 disappears. At this time, the plug-in iron block 610 begins to reset under the elastic action of the fifth spring 609, and instantly leaves the interior of the rectangular displacement frame 520, so that the rectangular displacement frame 520 and the plug-in iron block 610 are The clamping effect of the block 610 disappears, and under the elastic restoring effect of the fourth spring 506, the U-shaped lifting plate 507 slides downward between the two limiting round rods 322, driving the third lever 509 fixed to the two opposite sides of the first inclined plate 508 to synchronously slide in the two third sliding grooves 513 respectively penetrated through the two opposite sides of the H-shaped rotating plate 511, so that the rotating hole 512 penetrated through one side of the H-shaped rotating plate 511 is pulled down and rotated on the peripheral side of the rotating shaft 317, driving the fourth lever 515 slidingly matched on the inner walls of the two fourth sliding grooves 514 to synchronously press and slide upward, so that the L-shaped inclined plate 516 fixed between the two fourth levers 515 and the I-shaped sliding block fixed on one side of the L-shaped inclined plate 516 When the L-shaped inclined plate 516 fixed between the two fourth levers 515 and the I-shaped slider 517 fixed on one side of the L-shaped inclined plate 516 slide upward between the two U-shaped vertical plates 315, the L-shaped lifting plate 518 fixed on one side of the I-shaped slider 517 and the L-shaped lifting plate 518 are pressed upward and slid relative to the fifth levers 519 fixed on the two sides thereof in the second slide groove 504, driving the V-shaped rocker plate 501 in the linkage 5 that is rotated and matched in the hinge seat 314 to perform hinged rotation upward, thereby driving the V-shaped rocker plate 501 to slide in the opposite direction relative to the second levers 502 fixed on the two sides thereof in the two first slide grooves 405. The U-shaped plate 404 is moved to provide a force for sliding downward, and the third spring 406 fixedly connected between the outer top of the U-shaped plate 404 and the inner top of the built-in groove 312 is combined with the elastic force of the third spring 406, so that the top of the stripping rod 401 is located in the molding groove 303. The top of the stripping rod 401 is located in the molding groove 303. The ejection plate 402 fixed to the molding groove 303 is moved downward synchronously until the top of the stripping rod 401 is located in the molding groove 303. After the ejection plate 402 and the molding groove 303 are attached to each other, the next pressing process is carried out again. The whole process does not need to add an additional power source to perform the ejection and demolding operation on the already formed alloy rod-shaped metal, which can save energy and improve the working efficiency of the entire pressing and molding process, and effectively and continuously carry out the pressing and molding process of the alloy metal powder; In the above-mentioned process of knocking and cleaning, the second connecting flange 601 descends and rises to drive the movable inclined frame 603 fixed on the peripheral side of the second connecting flange 601 and the first lever 604 respectively fixed on the two opposite outer sides of the movable inclined frame 603 to slide back and forth on the inner walls of the two inclined slide grooves 718, thereby providing a horizontal moving force for the horizontal reciprocating movement of the discharge cover 702 on the trapezoidal groove 302, so that when the alloy metal powder attached to the inner peripheral side of the guide tube 705 is intermittently knocked and cleaned, the discharge cover 702 moves horizontally on the trapezoidal groove 302, and the discharge cover 702 is fixed on the slide. The elastic force of the second spring 723 between the movable plate 722 and the rectangular connecting frame 719 causes the extrusion plate 726 fixed at the bottom of the displacement plate 725 below the discharge cover 702 and the waste scraper 720 fixed at the bottom of the displacement plate 725 away from the extrusion plate 726 to slide repeatedly on the inner wall of the trapezoidal groove 302, thereby moving and scraping the alloy metal powder that falls into the inner wall of the trapezoidal groove 302, so that the alloy metal powder that falls into the inner wall of the trapezoidal groove 302 can finally fall into the interior of the molding groove 303 for the subsequent pressing operation, thereby avoiding the waste of alloy metal powder during the long-term pressing and molding transmission process.

After the raw material is supplied, the telescopic cylinder (308) is started, driving the pressing member (6) fixed to the telescopic end of the telescopic cylinder (308) to synchronously descend for pressing and ascend for ejection, so that the discharge member (7) slidably fitted on the pressing member (6) reciprocates horizontally above the trapezoidal groove (302); T3.

After the plug-in iron block (610) is instantly approached and snap-fitted into the rectangular displacement frame (520), the telescopic cylinder (308) contracts, driving the entire linkage member (5) to move, so that the stripping member (4) slidably fitted on the forming member (3) rises synchronously, thereby ejecting the formed alloy metal rod, thereby completing the ejection operation after the pressing and forming; T7. After the ejection operation after the pressing and forming is completed, the pressing plate (612) gradually approaches the second control button (321) and thereby generates pressure on the second control button (321), so that the second control button (321) starts to be activated. At this time, the electromagnet (510) electrically connected to the second control button (321) starts to be powered off and demagnetized, and the plug-in iron block (610) engaged in the interior of the rectangular displacement frame (520) starts to separate from the rectangular displacement frame (520) under the elastic action of the fifth spring (609); T8. After the rectangular displacement frame (520) is separated from the plug-in iron block (610), the entire linkage member (5) moves in the opposite direction, so that the sample stripping member (4) slidably engaged with the forming member (3) is synchronously lowered until the ejector plate (402) fixed to the top of the sample stripping rod (401) located inside the forming groove (303) is in contact with the forming groove (303) so as to carry out the next pressing process.
