Description

Technical Field

[0002] The carbide rod forming process is a process in which a mixture of alloy metal powders is pressed and combined together under the action of pressure; the advantages of alloy metal powder pressing and forming are low cost, fewer steps, high material utilization rate, and one-time forming. When processing a long cylindrical object in this way, a cavity is generally opened inside the mold, and metal powder is injected into the cavity, and then the alloy metal powder inside the cavity is compacted by the upper and lower compacting shafts.

[0059] 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 ends, the pressing column 602 of the device is located inside the molding groove 303 (at this time, the pressing column 602 after pressing and molding is located inside the molding groove 303, and there is a distance from the outer top of the molding groove 303. This distance is the pressing space for pressing and molding, ensuring that the entire alloy metal powder can be fully pressed to ensure the integrity of the molded alloy rod metal);

[0060] When it is necessary to demold the formed alloy rod-shaped metal, when the pressed-to-form pressing column 602 completes the final pressing action, the L-shaped extrusion plate 611 fixed to the side surface 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, 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 snap-fitted with the rectangular displacement frame 520. After the snap-fitting 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 shifting rod 509 fixed on the two opposite sides of the first inclined plate 508 to move synchronously in the H-shaped The rotating plate 511 slides inside the two third sliding grooves 513 respectively opened on the two side surfaces of the rotating plate 511, and thereby drives the rotating hole 512 opened on one side of the H-shaped rotating plate 511 to pull up and rotate on the peripheral side of the rotating shaft 317, so that the fourth lever 515 slidingly engaged 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 sliding groove 504, driving the V-shaped rocker 501 rotating in the linkage 5 and cooperating with the hinge seat 314 to synchronously press down and rotate, thereby driving the second lever 502 fixed on the two sides of the V-shaped rocker 501 to slide synchronously inside the two first sliding grooves 405, thereby providing a force for the upward sliding of the U-shaped plate 404, driving the sample removal 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 fixed between the outer top of the U-shaped plate 404 and the inner top of the built-in groove 312.The top of the stripping rod 401 is positioned within the molding groove 303 and the ejection plate 402 is synchronously moved upward. The contraction of the telescopic cylinder 308 allows the pressed alloy rod-shaped metal to be ejected synchronously. After the ejection process is completed, the ejected and pressed alloy rod-shaped metal is grasped and placed in another location by a robotic arm for subsequent operations (the robotic arm is conventional and is not shown here and will not be described in detail). The entire process does not require an additional power source to eject the formed alloy rod-shaped metal, thereby saving energy and improving the efficiency of the entire pressing process.

[0061] After the above-mentioned formed alloy rod 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 attraction 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 connected. The clamping effect of the block 610 disappears, and under the elastic restoring action 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 by the two opposite sides of the H-shaped rotating plate 511. The rotating hole 512 penetrated by 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 fitted 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 slider fixed on one side of the L-shaped inclined plate 516 The L-shaped lifting plate 518 fixed on one side of the I-shaped sliding block 517 and the L-shaped lifting plate 518 fixed on one side of the I-shaped sliding block 517 are synchronously pressed upward and slid relative to the fifth lever 519 fixed on both sides of the L-shaped lifting plate 518 in the second sliding 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 upward and rotate, thereby driving the V-shaped rocker plate 501 to synchronously slide in the opposite direction relative to the second lever 502 fixed on both sides. The U-shaped plate 404 is moved downwards, thereby providing a force for the downward sliding of the U-shaped plate 404. Combined with the elastic force of the third spring 406 fixed between the outer top of the U-shaped plate 404 and the inner top of the built-in groove 312, the top of the sample stripping rod 401 is located in the molding groove 303 and the ejector plate 402 fixed thereto moves downwards synchronously until the ejector plate 402 fixed thereto and the molding groove 303 are in contact with each other, and then the next pressing process is carried out again. The whole process does not require the addition of an additional power source to perform the ejection and demolding operation on the already formed alloy rod-shaped metal. While saving energy, it can also 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.

[0062] In the above-mentioned process of knocking and cleaning, the second connecting flange 601 is lowered and raised to drive the movable inclined frame 603 fixed on the side surface of the second connecting flange 601 and the first lever 604 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 horizontal reciprocating movement of the discharge cover 702 on the trapezoidal groove 302 is combined with the fixed connection 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, together with the waste scraper 720 fixed at the side of 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 eventually fall into the interior of the forming groove 303 for subsequent pressing operations, thereby avoiding the waste of alloy metal powder during the long-term pressing and molding transmission process.

10. The forming process of a press-forming die specifically for cemented carbide rods according to claim 9, characterized in that: The molding process includes the following steps: T1. When the alloy metal powder needs to be pressed and formed, first connect the powder connector (703) provided on the top of the discharge cover (702) to the outlet end of the alloy metal powder transmission device to ensure continuous supply of raw materials; T2. After the raw materials are 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) slidingly fitted on the pressing member (6) moves back and forth horizontally above the trapezoidal groove (302); T3. When the discharge member (7) synchronously reciprocates horizontally on the trapezoidal groove (302), the sliding ball (714) thereof sequentially contacts one side surface of the L-shaped side plate (305) and the surfaces of the plurality of protrusions (306) back and forth, causing the first spring (715) to be repeatedly compressed. This, combined with the elastic force of the first spring (715), drives the plurality of knocking balls (712) to repeatedly knock on the outer peripheral side surface of the guide tube (705), thereby performing intermittent knocking cleaning on the alloy metal powder attached to the inner wall of the guide tube (705); T4. During the knocking and cleaning process, the displacement plate (725) and the scraper (720) slide synchronously and repeatedly on the inner wall of the trapezoidal groove (302), thereby performing a scraping operation on the alloy metal powder that has fallen into the inner wall of the trapezoidal groove (302), so that the alloy metal powder that has fallen into the inner wall of the trapezoidal groove (302) can finally fall into the interior of the forming groove (303); T5. During steps T1 to T4, as the telescopic cylinder (308) is pressed and lowered, the pressing plate (612) gradually approaches the first control button (320), causing the first control button (320) to start, and the electromagnet (510) to start energizing and generating magnetism, thereby generating a magnetic attraction force on the plug-in iron block (610), driving the plug-in iron block (610) to instantly approach and snap fit inside the rectangular displacement frame (520); T6. After the plug-in iron block (610) is instantly brought close to and snap-fitted into the rectangular displacement frame (520), the telescopic cylinder (308) contracts, driving the entire linkage (5) to move, causing the stripping member (4) slidingly fitted on the forming member (3) to rise synchronously, thereby ejecting the formed alloy metal rod, thereby completing the ejection operation after the pressing and forming process; 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 (5) moves in the opposite direction, causing the sample stripping member (4) that is slidably engaged with the forming member (3) to descend synchronously until the ejection plate (402) fixed on the top of the sample stripping rod (401) located inside the forming groove (303) and the forming groove (303) are in contact with each other, so as to carry out the next pressing process.
