Description

Technical Field

[0001] The invention relates to the technical field of cemented carbide ultra-thin circular blades, and more specifically to a production process of cemented carbide ultra-thin circular blades. Background Art

[0002] Cemented carbide inserts are made of cemented carbide, which is an alloy material made from hard compounds of refractory metals and bonding metals through powder metallurgy. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance. In particular, its high hardness and wear resistance remain basically unchanged even at a temperature of 500°C, and it still has a high hardness at 1000°C.

[0003] According to the patent document: CN104476333A, a grinding device for cemented carbide ultra-thin circular blades is disclosed, which belongs to the technical field of production devices for producing cemented carbide. A grinding device for cemented carbide ultra-thin circular blades of the present invention includes a circular plate-shaped connecting sleeve, a bearing seat, a bearing, a connecting pipe and a vacuum pump, and also includes a tapered handle, a tapered sleeve and an arc-shaped groove arranged on the surface of a circular adsorption mold; the left end of the tapered handle is completely embedded in and welded in the stepped hole on the right side of the circular plate-shaped connecting sleeve; the tapered handle is inserted from the left end of the tapered sleeve into the circular cavity of the tapered sleeve, and is tightly connected with the circular cavity of the tapered sleeve; the right end of the tapered sleeve is fixedly connected with the truncated cone-shaped structure of the bearing seat; one end of the connecting pipe is fixedly connected with the spacer sleeve of the bearing, and the other end is connected with the vacuum pump through a pipeline; the surface of the circular adsorption mold is evenly provided with circular adsorption holes, and the circular adsorption holes are connected with the circular gaps; arc-shaped grooves are arranged between the circular adsorption holes. The present invention can achieve the purpose of evenly and firmly clamping cemented carbide ultra-thin circular blades for grinding;

[0004] When preparing cemented carbide blades, they need to be placed in a special mold for pressing and forming. Pressing is to put the ingredients into the mold and press them to obtain a cemented carbide blank of basic shape and size. During the pressing process, it is necessary to control parameters such as pressing pressure, temperature and time to ensure the density and strength of the blank. At the same time, during the pressing process, it is also necessary to pay attention to the cleaning and maintenance of the mold to prevent the generation of impurities and cracks. However, most of the existing pressing devices are generally set to be exposed to the outside, which is easily affected by the external environment, resulting in the contamination of the cemented carbide raw materials during the pressing process, thereby affecting the quality and performance of the product. At the same time, the existing pressing devices are often only capable of pressing and forming one type of mold during the pressing process. When it is necessary to press cemented carbide blades of different types, the mold needs to be replaced, which is cumbersome to operate and is not suitable for large-scale production.

[0005] In addition, the evenly mixed cemented carbide raw materials are placed in a special mold for pressing and forming. During the pressing process, most pressing devices fail to fix the mold. During the pressing process, the fixation of the mold is crucial to ensure the accuracy and stability of the blade blank. Failure to fix the mold may cause the mold to shift or deform, thereby affecting the accuracy and consistency of the blade blank. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a production process for cemented carbide ultra-thin circular blades. The technical problem to be solved by the present invention is that most pressing devices are generally arranged to be exposed to the outside, which is easily affected by the external environment, resulting in contamination of the cemented carbide raw materials during the pressing process, thereby affecting the quality and performance of the product. At the same time, the existing pressing devices can often only perform pressing and molding for one type of mold during the pressing process. When different types of cemented carbide blades need to be pressed, the mold needs to be replaced, the operation is cumbersome, and it is not suitable for large-scale production. In addition, the evenly mixed cemented carbide raw materials are placed in a special mold for pressing and molding. During the pressing process, most of the pressing devices fail to fix the mold. During the pressing process, the fixation of the mold is crucial to ensuring the accuracy and stability of the blade blank. Failure to fix the mold may cause the mold to shift or deform, thereby affecting the accuracy and consistency of the blade blank.

[0042] Step 1: Mix the precisely proportioned cemented carbide raw materials to ensure the uniformity of the raw materials. During the mixing process, strictly control the temperature and humidity of the raw materials to prevent oxidation or moisture from occurring during the mixing process, which may affect the quality of subsequent processing.

[0043] Step 2: Put the mixed carbide raw materials into a special mold for pressing. During the pressing process, strictly control the pressing pressure and pressing time to ensure that the density and strength of the blade blank meet the predetermined requirements. At the same time, the design and selection of the mold are also crucial, which directly affects the shape and dimensional accuracy of the blade blank.

[0044] Step 3: The pressed blade blank is subjected to high-temperature sintering. During the sintering process, the sintering temperature and sintering time need to be precisely controlled so that the tungsten carbide particles in the cemented carbide raw material are fully combined with the cobalt binder to form a solid cemented carbide material. At the same time, in order to prevent the blade from deforming or cracking during the sintering process, the sintering environment needs to be strictly controlled;

[0045] Step 4: Finely grind the sintered blade. By selecting appropriate grinding tools and grinding processes, ensure that the surface smoothness and dimensional accuracy of the blade meet the use requirements. In addition, the grinding temperature must be controlled during the grinding process to avoid cracks or deformation of the blade due to overheating;

[0052] When pressing is required, first place the material to be pressed in the mold box 10, then place the mold box on the mold box placement plate body 331, then start the turntable 2 to turn one of the mold box fixing tables 3 to the bottom of the bottom groove 9 of the pressing chamber, then start the motor 329, the output end of the motor 329 drives the rotating rod 3210 to rotate, and then drives the second gear 3211 to rotate, because the second gear 3211 is meshed with the third gear 3212, the third gear 3212 will also rotate with the rotation of the second gear 3211, and at the same time, the second rotating rod 3213 fixedly connected to the inner wall of the third gear 3212 plays a supporting and stabilizing role to ensure the smooth operation of the gear;

[0053] As the third gear 3212 rotates, its outer wall meshes with a plurality of tooth blocks 3215 arranged in an annular array at the bottom of the transmission top shaft 3214, thereby driving the transmission top shaft 3214 to rotate inside the cylindrical rotating bin 327. The rotation of the transmission top shaft 3214 is further meshed with the two sub-gears 326 through the fourth gear 3216, driving the two screw rods 325 to rotate synchronously. Since the outer wall of the screw rod 325 is threadedly connected to the inner wall of the transmission plate 314, the rotation of the screw rod 325 drives the transmission shaft housing 321 to achieve lifting movement on the vertical plate 313, thereby adjusting the height of the mold box placement plate 33 to match the position of the pressing chamber bottom groove 9 and rise to the inside of the pressing chamber 7 through the pressing chamber bottom groove 9;

[0054] At the same time, as the transmission top shaft 3214 rotates, the top rotating rod 3217 rotates and drives the control rotating plate 341 to rotate. The rotation of the control rotating plate 341 drives the slider 343 to slide in the slide groove 333 through the L-shaped rotating rod 342, thereby driving the clamping column 348 to approach the mold box to clamp and fix the mold box. Due to the setting of the push-pull rod connecting block 344, the push-pull rod 345, the push-pull block 346 and the telescopic rod 347, the two groups of clamping columns 348 will move closer or farther away synchronously to ensure the stability and uniformity of the clamping. Through this design, it is possible to achieve adaptive clamping of mold boxes of different sizes, thereby improving the versatility and flexibility of the equipment.

[0055] After the clamping is completed, the turntable 2 continues to rotate to send the mold box placement plate 33 fixed with the mold box 10 into the pressing chamber 7. After the mold box is in place, the pressing operation will be carried out to press the material into shape according to the shape of the mold box. After the pressing is completed, the motor 329 will start again to drive the transmission top shaft 3214 to rotate in the opposite direction, drive the control rotating plate 341 to rotate in the opposite direction, and then drive the clamping column 348 to release the mold box, allowing it to be removed from the mold box placement plate 33. At the same time, the two screw rods 325 reverse and drive the transmission shaft housing 321 to descend, so that the mold box placement plate 33 is moved out of the pressing chamber 7. Through the rotation of the turntable 2 again, the pressed mold box is sent to the next process for subsequent processing, such as demoulding, cooling, etc.

[0056] At this time, the turntable 2 is started again, the mold box 10 that has been pressed is taken out from the pressing chamber 7, and rotated to the next station to perform the next round of pressing operation.

[0057] Working principle of the present invention: When it is necessary to press according to different models of mold boxes 10, first, the models of several pressers 46 fixed to the outer wall of the rotating shaft 45 are different, the presser control frame 4 starts to work, the second motor 442 is started, and the transmission column rotating rod 443 is driven to rotate in the transmission column body 441. The rotational motion of the transmission column rotating rod 443 is transmitted to the two transmission column sub-gears 446 through the transmission column gear 445. Due to the meshing relationship between the transmission column gear 445 and the two transmission column sub-gears 446, the transmission column sub-gears 446 rotate in the opposite direction on the outer wall of the transmission column body 441. This rotational motion is transmitted to the transmission column gear 445 through the transmission column gear 445. 5 is transmitted to the press 46. At the same time, due to the meshing of the second tooth block 454 provided on the inner wall of the inner shaft 453 and the transmission column pinion 446, when the transmission column pinion 446 rotates, it will drive the inner shaft 453 and the semicircular rotating plate 452 thereon to slide on the semicircular slide plate 447, and drive the press 46 to perform a circular motion. The press 46 is aligned with the bottom groove 9 of the pressing chamber to press the materials placed in the mold boxes 10 of different types that need to be pressed and formed. During the pressing process, the transparent rubber plate 8 can clearly display the contact between the press 46 and the mold box 10, so that the operator can monitor the pressing process in real time.

[0058] When pressing is required, first place the material to be pressed in the mold box 10, and then place the mold box on the mold box placement plate body 331, then start the turntable 2 to rotate one of the mold box fixing tables 3 to the bottom of the bottom groove 9 of the pressing chamber, and then start the motor 329. The output end of the motor 329 drives the rotating rod 3210 to rotate, and then drives the second gear 3211 to rotate. Since the second gear 3211 is meshed with the third gear 3212, the third gear 3212 will also rotate with the rotation of the second gear 3211. At the same time, the second rotating rod 3213 fixedly connected to the inner wall of the third gear 3212 plays a supporting and stabilizing role to ensure the smooth operation of the gear. With the rotation of the third gear 3212, its outer wall is meshed with a plurality of tooth blocks 3215 arranged in an annular array at the bottom of the transmission top shaft 3214, thereby driving the transmission The top shaft 3214 rotates inside the cylindrical rotating bin 327, and the rotation of the transmission top shaft 3214 is meshed with the two sub-gears 326 through the fourth gear 3216, driving the two screw rods 325 to rotate synchronously. Since the outer wall of the screw rod 325 is threadedly connected to the inner wall of the transmission plate 314, the rotation of the screw rod 325 will drive the transmission shaft housing 321 to realize lifting movement on the vertical plate 313, thereby adjusting the height of the mold box placement plate 33 so that it matches the position of the bottom groove 9 of the pressing chamber and rises to the inside of the pressing chamber 7 through the bottom groove 9 of the pressing chamber. At the same time, as the rotation of the transmission top shaft 3214 drives the top rotating rod 3217 to rotate and drives the control rotating plate 341 to rotate, the rotation of the control rotating plate 341 drives the slider 343 to slide in the slide groove 333 through the L-shaped rotating rod 342, thereby driving the clamping column 348 to approach the mold box to clamp and fix the mold box. Due to the arrangement of the push-pull rod connecting block 344, the push-pull rod 345, the push-pull block 346 and the telescopic rod 347, the two groups of clamping columns 348 will move closer or farther away synchronously to ensure the stability and uniformity of clamping. Through this design, adaptive clamping of mold boxes of different sizes can be achieved, which improves the versatility and flexibility of the equipment. After the clamping is completed, the turntable 2 continues to rotate to send the mold box placement plate 33 with the mold box 10 fixed thereon into the pressing chamber 7. After the mold box is in place, a pressing operation will be performed to press and form the material according to the shape of the mold box. After the pressing is completed, the motor 329 will start again. , driving the transmission top shaft 3214 to rotate in the opposite direction, driving the control rotating plate 341 to rotate in the opposite direction, and then driving the clamping column 348 to loosen the mold box, allowing it to be removed from the mold box placement plate 33, and at the same time the two screw rods 325 reverse, driving the transmission shaft housing 321 to descend, so that the mold box placement plate 33 is moved out from the inside of the pressing chamber 7, and the turntable 2 rotates again to send the pressed mold box to the next process for subsequent processing, such as demoulding, cooling, etc. At this time, the turntable 2 is started again, the pressed mold box 10 is taken out of the pressing chamber 7, and rotated to the next station for the next round of pressing operation.
