Description

Technical Field

[0001] The invention relates to the field of forming dies, and more particularly to a forming die for a metal-ceramic alloy part. Background Art

[0002] Metal-ceramic alloy parts are heterogeneous composite materials composed of metal or alloy and one or more ceramic phases. This material is made by powder metallurgy or other advanced manufacturing processes, aiming to combine the respective advantages of metal and ceramic. According to the difference between ceramic phase and metal phase, metal-ceramic alloy parts can be divided into many types, such as carbide-based metal-ceramics (such as WC-Co-based metal-ceramics), nitride-based metal-ceramics, oxide-based metal-ceramics, etc.

[0003] The production process of metal-ceramic alloy parts usually includes the following steps: powder preparation: preparing metal oxides and other raw materials into metal or metal carbide powder through reduction, carbonization and other reactions; mixture preparation: mixing ceramic powder and metal or alloy powder in a certain proportion, and further grinding them; molding: using dry pressing, grouting, extrusion and other molding methods to make the mixture into a blank of the desired shape; firing: high-temperature firing in a vacuum or reducing atmosphere to make the ceramic phase and the metal phase closely combine to form a composite material.

[0004] In the prior art, before dry pressing of metal-ceramic alloy parts, multiple ceramic powders and metal powders need to be finely ground and mixed.

When the high-speed airflow blows toward the impeller, the powder material inside the impeller will also be blown up, so that various powders can be fully mixed. The high-speed airflow blown into the mold is weakened by the impeller, which not only avoids blowing the powder material out of the mold, but also blows the accumulated powder material to the surroundings to prevent the uneven distribution of the powder material from affecting the dry pressing efficiency.

[0021] (3) The present invention drives the sealing plate to move by means of the movable plate, so that the sealing plate seals the discharge port after the pressure rod enters the mold. Since the pressure rod transports the powder material during the process of entering the mold, the powder material is prevented from leaking out of the mold during the transportation process, and dry pressing is achieved immediately after the feeding is completed, which effectively improves the dry pressing efficiency of the powder material.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 A forming die for a metal-ceramic alloy part includes a dry pressing forming machine 1, which is composed of a bracket 101, a mold 102, a cylinder 103 and a pressure rod 104. The mold 102 is overlapped on the lower side of the inner part of the bracket 101, the cylinder 103 is fixedly installed on the upper side of the inner part of the bracket 101, and the pressure rod 104 is fixedly connected to the output end of the cylinder 103. The pressure rod 104 moves downward and is inserted into the mold 102. The pressure rod 104 is provided with a material shaking component 2 inside. The material shaking component 2 includes a high-pressure blowing pipe 21 inserted into the pressure rod 104;

[0034] The pressure rod 104 is internally connected to the impeller 22, and the front and rear sides of the impeller 22 are fixedly connected to the rotating disk 23. The outer side of the extension of the two rotating disks 23 away from each other is sleeved with a moving seat 24. After the rotating disk 23 rotates, the moving seat 24 reciprocates left and right. The two moving seats 24 are slidably connected to the inside of the pressure rod 104. The two moving seats 24 penetrate the pressure rod 104. The outer side of the pressure rod 104 is provided with a movable groove 25. The number of the movable grooves 25 is four, and the insides of the four movable grooves 25 are hinged. A strike plate 26 is connected, and a first pressure spring 27 is fixedly connected to one side of the strike plate 26 close to the moving seat 24. The other end of the first pressure spring 27 is fixedly connected to the side of the movable groove 25 close to the moving seat 24. The side of the strike plate 26 close to the first pressure spring 27 is in squeeze contact with the side of the moving seat 24 close to the strike plate 26. After the moving seat 24 leaves the strike plate 26, the strike plate 26 is pushed by the first pressure spring 27. After the first pressure spring 27 pushes the strike plate 26, the strike plate 26 hits the inner wall of the mold 102.

[0035] By adopting the above technical solution, the mold 102 is first placed inside the bracket 101 of the dry pressing molding machine 1, and then the cylinder 103 drives the pressure rod 104 to move downward. When the pressure rod 104 gradually enters the mold 102, the high-pressure blowing tube 21 will transport the powder material through the high-speed airflow and blow it to the impeller 22 inside the pressure rod 104. When the high-speed airflow blows to the impeller 22, the impeller 22 will simultaneously drive the two turntables 23 to rotate inside the pressure rod 104. Since the moving seat 24 is always mounted on the outside of the extension of the turntable 23, when the turntable 23 rotates one circle, the moving seat 24 will move back and forth left and right once. In the process of the moving seat 24 moving left and right on one side, it will enter the two movable grooves 25 respectively, and push the lower part of the impact plate 26 hinged inside the movable groove 25. At this time, the impact plate 26 starts to rotate inside the movable groove 25 with the extension parts on both sides as the center, so that the impact plate 26 squeezes the first pressure spring 27. Then, after the movable seat 24 is separated from the corresponding impact plate 26, the first pressure spring 27 will push the upper part of the impact plate 26 through its own elasticity. If the pressure rod 104 enters the mold 102 at this time, the impact plate 26 will hit the inner wall of the mold 102, causing the powder material inside the mold 102 to shake. After entering the mold 102, the pressure rod 104 will hit the inner wall of the mold 102 through the impact plate 26, and the shaking generated during the collision will cause the powder material to shake, making the powder material more compact after the shaking, effectively reducing the possibility of small cracks or small holes in the formed blank.

[0036] like Figures 2 to 6As shown, the pressure rod 104 is composed of two identical semi-cylinders, the high-pressure blowing pipe 21 is located at the upper right of the impeller 22, and a feeding assembly 28 is provided inside the pressure rod 104. The feeding assembly 28 includes a cavity 281 opened inside the pressure rod 104.

[0037] The impeller 22 is located inside the cavity 281 , the high-pressure blowing pipe 21 is connected to the cavity 281 , a discharge port 282 is provided on the lower side of the pressure rod 104 , the discharge port 282 is located directly above the mold 102 , and the discharge port 282 is connected to the cavity 281 .

[0038] By adopting the above technical solution, first, the high-pressure blowing tube 21 blows the powder material to the impeller 22, and the impeller 22 will collect the powder material, and the impeller 22 will also start to rotate through the high-speed airflow, so that the powder material is slowly transported inside the cavity 281, and then discharged into the mold 102 through the discharge port 282. When the high-speed airflow blows to the impeller 22, the powder material inside the impeller 22 will also be blown up, so that various powders can be fully mixed, and the high-speed airflow blown into the mold 102 is weakened by the impeller 22 after being blocked, which not only avoids blowing the powder material out of the mold 102, but also blows the accumulated powder material to the surroundings to prevent the uneven distribution of the powder material from affecting the dry pressing efficiency.

[0039] like Figure 4 and Figure 5 As shown, a blocking component 29 is provided inside the pressure rod 104 , and the blocking component 29 includes a moving groove 291 opened inside the pressure rod 104 , so the number of the moving grooves 291 is two, and the two moving grooves 291 are connected to the same discharge port 282 .

[0040] The interior of the two movable grooves 291 is slidably connected with a movable plate 292, and the opposite surfaces of the two movable plates 292 are fixedly connected with a second pressure spring 293, and the number of the single-side second pressure springs 293 is multiple, and the other ends of the multiple second pressure springs 293 are commonly fixedly connected to the side of the movable groove 291 close to the impeller 22, and the opposite surfaces of the two movable plates 292 are fixedly connected with a sealing plate 294. After the pressure rod 104 is inserted into the mold 102, the two movable plates 292 are moved away from each other and are slidably and squeezed into contact with the inner wall of the mold 102. The two sealing plates 294 are fitted together to seal the discharge port 282.

[0041] By adopting the above technical scheme, first, before the pressure rod 104 enters the interior of the mold 102, the sealing plate 294 used to seal the discharge port 282 is pushed by the second pressure spring 293 to the movable plate 292 and retracted into the interior of the movable groove 291. At this time, the powder material can be discharged from the discharge port 282. After the pressure rod 104 enters the interior of the mold 102, the movable plate 292 extending from the interior of the movable groove 291 will first contact the inner wall of the mold 102. At this time, the movable plate 292 is squeezed by the inner wall of the mold 102 and retracts into the movable groove 291, and the two sealing plates 294 will seal the discharge port 282 after merging. Finally, the powder material is dry-pressed by the pressure plate and the sealing plate 294. Since the pressure rod 104 will convey the powder material in the process of entering the mold 102, it is avoided that the powder material leaks out of the mold 102 during the conveying process, and the immediate dry pressing after the feeding is completed is realized, which effectively improves the dry pressing efficiency of the powder material.

[0042] like Figure 2 , Figure 7 and Figure 8 As shown, a material stripping component 3 is provided on the outer side of the pressing rod 104 and the outer side of the mold 102 . The material stripping component 3 includes a fixing frame 31 fixedly connected to the outer side of the pressing rod 104 .

[0043] A card slot 32 is provided on the lower inner side of the fixed frame 31, and a limiting slot 33 is provided inside the card slot 32, and there are two limiting slots 33. Card blocks 34 are slidably connected inside the two limiting slots 33, and third pressure springs 35 are sleeved on the outer sides of the two card blocks 34. The sides of the two card blocks 34 that are away from each other are fixedly connected to one end of the opposite surfaces of the two third pressure springs 35, and the sides of the two third pressure springs 35 that are away from each other are fixedly connected to the sides of the two limiting slots 33 that are away from each other. The two card blocks 34 both penetrate the fixed frame 31, and a fixed seat 36 is fixedly connected to the outer side of the mold 102. After the fixed frame 31 moves downward, it is sleeved on the outer side of the fixed seat 36 through the card slot 32. After the two card blocks 34 move downward, they slide and squeeze contact with the upper side of the same fixed seat 36, and after the two card blocks 34 move upward, they squeeze contact with the outer side of the same fixed seat 36.

[0044] The outer side of the pressure rod 104 and the outer side of the mold 102 are jointly provided with a lifting assembly 37, and the lifting assembly 37 includes an outer sliding sleeve of a fixed seat 36 provided with a movable disk 371. After the two clamping blocks 34 move downward, they slide and squeeze contact with the outer side of the same movable disk 371. After the two clamping blocks 34 move upward, they squeeze contact with the lower side of the same movable disk 371. After the movable disk 371 moves upward, it squeezes contact with the outer side of the fixed seat 36. After the two clamping blocks 34 contact the outer side of the fixed seat 36, the mold 102 is lifted through the fixed seat 36.

[0045] By adopting the above technical solution, first, during the downward movement of the pressing rod 104, the pressing rod 104 will drive the fixed frame 31 to move downward together. When the fixing seat 36 outside the mold 102 enters the slot 32 below the fixing frame 31, it will first squeeze the block 34 inside the limiting slot 33, and the block 34 is pushed by the third pressure spring 35 inside the limiting slot 33. As the fixing seat 36 gradually goes deeper, the block 34 will be inserted under the upper protrusion of the fixing seat 36 through the elasticity of the third pressure spring 35. When the powder material is dry-pressed and the pressing rod 104 is lifted, the fixing frame 31 will lift the fixing seat 36 through the block 34 inside it, so that the mold 102 will also be lifted up. At this time, the dry-pressed material will be discharged from the bottom of the mold 102. After the material is returned, the cylinder 103 pushes the pressing rod 104 downward, so that the mold 102 is placed again inside the bracket 101. At this time, because the material inside the mold 102 is taken out, the pressure rod 104 can move downward a distance again, so that the block 34 contacts the movable plate 371 and passes through the movable plate 371. Due to the elastic force of the third pressure spring 35, the block 34 will fit tightly with the outer side of the movable plate 371. When the pressure rod 104 moves upward again, the block 34 will drive the movable plate 371 to move upward. After the movable plate 371 contacts the upper protrusion of the fixed seat 36, the movable plate 371 stops moving. At this time, the block 34 will slide to the outer side of the fixed seat 36 with the help of the inclined surface of the movable plate 371, and finally disengage from the fixed seat 36, so that the mold 102 is no longer lifted. Since the powder material will be lifted together with the mold 102 after dry pressing is completed, the dry pressed material can be quickly withdrawn, thereby realizing the continuous operation of dry pressing and material withdrawal, avoiding the need to invert the mold 102 for material withdrawal after the powder material is dry pressed.

[0046] like Figure 2 , Figure 7 and Figure 8 As shown, a lubrication assembly 38 is provided on the inner lower side of the bracket 101 and the upper side of the mold 102 . The lubrication assembly 38 includes an extrusion seat 381 fixedly connected to the lower side of the fixed frame 31 .

[0047] A storage box 382 is fixedly installed on the lower inner side of the bracket 101, and an extrusion seat 381 passes through the upper side of the storage box 382. The extrusion seat 381 is slidably connected to the inside of the storage box 382. A delivery pipe 383 is inserted into the upper side of the storage box 382, ​​and there are two delivery pipes 383. One end of the two delivery pipes 383 close to the storage box 382 passes through the extrusion seat 381 together, and the other ends of the two delivery pipes 383 are inserted into the upper side of the mold 102. The two delivery pipes 383 are connected to the interior of the same mold 102.

[0048] By adopting the above technical solution, first, during the downward movement of the fixed frame 31, the fixed frame 31 will drive the extrusion seat 381 to move downward. At this time, the lower part of the extrusion seat 381 will be inside the storage box 382. After the lubricant inside the storage box 382 squeezes the air through the extrusion seat 381, one end of the conveying pipe 383 extends to the upper side of the mold 102 and is connected to the inside of the mold 102, while the other end is inserted into the storage box 382 and passes through the extrusion seat 381, so that the lubricant enters the mold 102 through the conveying pipe 383. As the pressure rod 104 moves downward, the lubricant in the storage box 382 will also be squeezed into the mold 102. On the one hand, the heat generated by the mutual friction of the powder materials when the pressure rod 104 squeezes the powder materials is cooled, and it is convenient to return the dry pressed materials. On the other hand, the powder materials remaining on the outside of the pressure rod 104 and inside the mold 102 are cleaned to reduce the friction between the pressure rod 104 and the mold 102.

[0049] Working principle: first, the mold 102 is placed inside the bracket 101 of the dry pressing molding machine 1, and then the cylinder 103 drives the pressure rod 104 to move downward, and the high-pressure blowing tube 21 blows the powder material to the impeller 22 inside the pressure rod 104 through the high-speed airflow. At this time, the impeller 22 simultaneously drives the two turntables 23 to rotate inside the pressure rod 104. Because the moving seat 24 is always set on the outside of the extension of the turntable 23, when the turntable 23 rotates one circle, the moving seat 24 will move back and forth left and right once. In the process of the moving seat 24 moving left and right on one side, it will enter the two movable grooves 25 respectively, and push the lower part of the impact plate 26 hinged in the movable groove 25, so that the impact plate 26 squeezes the first pressure spring 27, and then the moving seat 24 and the corresponding After the collision plate 26 is disengaged, the first pressure spring 27 will push the upper part of the collision plate 26 through its own elasticity. If the pressure rod 104 enters the mold 102 at this time, the collision plate 26 will hit the inner wall of the mold 102. The impeller 22 collects the powder material and discharges it into the mold 102 through the discharge port 282. First, before the pressure rod 104 enters the mold 102, the blocking plate 294 used to block the discharge port 282 is pushed by the second pressure spring 293 to push the moving plate 292 and retract into the moving groove 291. As the pressure rod 104 enters the mold 102, the moving plate 292 extending from the moving groove 291 will first contact the inner wall of the mold 102. At this time, the moving plate 292 is squeezed by the inner wall of the mold 102 and retracts into the moving groove 291, and the two blocking plates 294 will block the discharge port 282 after merging. During the downward movement of the pressing rod 104, the pressing rod 104 will drive the fixed frame 31 to move downward together. After the fixed seat 36 on the outside of the mold 102 enters the slot 32 below the fixed frame 31, it will first squeeze the block 34 inside the limit slot 33. As the fixed seat 36 gradually goes deeper, the block 34 will be elastically inserted under the upper protrusion of the fixed seat 36 through the third pressure spring 35. When the powder material is dry-pressed and the pressing rod 104 is lifted, the fixed frame 31 will lift the fixed seat 36 through the block 34 inside it, so that the mold 102 will also be lifted up, and the dry-pressed material will be discharged from the bottom of the mold 102. After the material return is completed , the cylinder 103 pushes the pressure rod 104 downward, so that the mold 102 is placed again inside the bracket 101. At this time, because the material inside the mold 102 is taken out, the pressure rod 104 can move downward for a distance, so that the block 34 contacts with the movable plate 371 and passes through the movable plate 371. Due to the elastic force of the third pressure spring 35, the block 34 will fit tightly with the outer side of the movable plate 371. When the pressure rod 104 moves upward again, the block 34 will drive the movable plate 371 to move upward. After the movable plate 371 contacts the upper protrusion of the fixed seat 36, the movable plate 371 stops moving. At this time, the block 34 will slide to the outer side of the fixed seat 36 with the help of the inclined surface of the movable plate 371, and finally disengage from the fixed seat 36, so that the mold 102 is no longer lifted.When the fixed frame 31 drives the extrusion seat 381 to move downward, the lubricant in the storage box 382 squeezes the air through the extrusion seat 381 and enters the delivery pipe 383.
