Generally, a powder compression molded product has a cylindrical body, an ellipsoid, or a prismatic body. That is, powder is filled into a cylindrical or square cylindrical mortar, and the tip of the tip is compression-molded with a planar upper and lower heel, but depending on the use such as electrical parts, it is not necessarily There is a demand for a molded product having a step having a shape that cannot be produced with a flat-shaped heel.

  Therefore, a stepped portion corresponding to the step required by the molded product is formed in the tip portion of the upper or lower punch, and the molded product having the step is manufactured by compressing with a ridge having the stepped portion.

  When a molded product having a step is paid out from the tip of the lower heel, it is necessary to prevent the step of the molded product from being caught by a step portion of the heel of the lower heel and being lost. For example, as shown in Non-Patent Document 1, according to the basic concept of a conventional molding method of a molded product by uniaxial compression, in the case of a molded product having a step in the compression direction, depending on its shape The lower iron is divided and the lower two-stage molding method or the lower three-stage molding method is applied. In particular, when one side has a step in the compression direction and the opposite surface is a flat molded product, it is common sense that the surface having the step is formed on the lower side and the flat side is formed on the upper side. It is. Further, in the case of a molded product having steps on both sides, it is common to form a more complicated surface with steps on the lower side and make the step on the upper side as small as possible.

And when paying out the molded product having a step from the tip of the lower iron, the step of the molded product having the step becomes the step portion of the lower iron tip by flattening the tip surface of the divided lower iron This prevents the molded product from being damaged.

  Conventionally, when producing a molded product having a step with a rotary powder compression molding machine, the lower punch is divided on the structure of the molding machine, and the tip height of each divided lower punch is freely adjusted. Since the tip of the lower iron cannot be flattened when the molded product is paid out from the tip of the lower iron, the step of the molded product having a step is formed on the step of the tip of the lower iron. There was a problem that the molded product was damaged and was damaged.

  Therefore, in a conventional rotary powder compression molding machine, when molding a molded product having a step in the compression direction on one side and a flat surface on the opposite side, the surface having the step is molded on the upper heel side and is flat. It was common knowledge that the surface was molded on the lower side.

  In a conventional rotary powder compression molding machine, when a molded product having steps on both end surfaces is stepped out from the tip of the lower iron, the step of the molded product having a step is caught by the step on the tip of the lower iron. Since the molded product has defects, it cannot be molded.

  In addition, when a molded product having a step as shown in FIG. 3 is to be paid out from the tip of the lower iron, it is not necessary to flatten the tip surface of the lower iron, but it is slid in the horizontal direction from the lower iron tip. If the molded product is dispensed in the direction in which it can be dispensed, that is, if the molded product on the lower iron tip is moved horizontally, the step of the molded product will not catch on the step on the lower iron tip. No defects occur in the molded product.

  However, in the conventional rotary powder compression molding machine, the position where the molded product is discharged from the tip of the lower punch by the separation / discharge scraper is the same as the position where the molded product is discharged out of the rotating disk by the separation / discharge scraper. Since the direction in which the molded product is discharged from the tip of the lower punch by the separation / discharge scraper is different from the direction in which the molded product can be slid in the horizontal direction from the tip of the lower punch, When the molded product is dispensed from the tip of the heel, a step of the molded product is caught at the tip of the lower heel and the molded product is damaged. For this reason, it is impossible to cause a molded product having a level difference as in the conventional case to be discharged from the rotating disk at the same time as it is dispensed from the tip of the lower iron by the separation / discharge scraper arranged on the rotating disk. there were.

  The present invention has been made in view of the above circumstances, and a step of a molded product having a step that can be slid in the horizontal direction from the tip of the lower iron is caught by the tip of the lower iron and is lost. It is an object of the present invention to provide a rotary powder compression molding machine and a compression molding method thereof.

  As a result of intensive studies, the present inventors have determined that the molded product separation position, which is a position for discharging the molded product from the tip of the lower iron, and the molded product discharge position, which is a position for discharging the molded product to the outside of the rotating disk, are different positions. As a result of the installation, the inventors have found that the above object can be achieved, and have reached the present invention.

That is, the rotary powder compression molding machine according to the present invention slides from the lower side to the rotary disk, one or more mortars provided in the rotary disk and having through holes penetrating in the vertical direction, and the through holes of the respective mortars.

By applying To the resulting molded article, payment in sliding contact from the punch tip portion of the punch under with the rotation of the upper Symbol turntable horizontally along the upper Symbol stepped surface該杵destination molded article A molded product separating means for discharging, and a molded product discharging means for discharging the molded product discharged by the molded product separating means installed at a position different from the molded product separating means to the outside of the rotating disk, and Along with the rotation of the board, a powder supply process, a powder compression process, a molded product separation process, and a molded product discharge process are sequentially performed.

Further, the molded product separating means includes a separation portion for discharging the molded product, a separation height track portion for forming a lower rail for separating the molded product, and a height of the separation height track portion. and a separation height adjustment unit for adjusting a with placing on the SL separating portion at a position spaced apart from the surface of the upper Kiusu upward, when discharging along the top Symbol moldings on SL stepped surface in, wherein the by the upper SL separating unit Kikine destination portion on the upper SL under punch was controlled on SL under punch to project to a height position that enables dispensing of the molded article.

  Further, the molded product discharge means includes a discharge portion for discharging the molded product, a discharge height track portion for forming a lower track for discharging the molded product, and a height of the discharge height track portion. A discharge height adjusting unit for adjusting the discharge height.

  And the compression molding method using the rotary powder compression molding machine in the present invention is a molding product having a step obtained by pressurizing the upper and lower irons in cooperation with the rotation of the rotating disk. After paying out by the molded product separating means, the molded product discharging means discharges it outside the rotating disk.

  As described above, according to the present invention, the position where the molded product is discharged from the tip of the lower iron and the position where the molded product is discharged out of the turntable are installed at different positions, and the molded product is removed from the tip of the lower iron. Place the molded product in a direction in which it can be slid in the horizontal direction, that is, when the molded product on the tip of the lower iron is moved horizontally, the step of the molded product does not get caught on the tip of the lower iron. By paying out, a molded product free from defects can be obtained.

  Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, a rotary powder compression molding machine according to the present invention includes a rotating disk 101, one or more mortars 102 provided in the rotating disk 101 and having through holes penetrating in the vertical direction. The lower punch 104, which is slidably inserted into the through-hole 102 from the lower side and has a stepped portion at the tip, moves with the rotation of the rotary disk 101, and is surrounded by the die 102 and the lower punch 104. Powder supply means for supplying powder into the cavities, and powders supplied by the powder supply means that are inserted into the through-holes of the respective dies 102 so as to be detachable from the upper side and move as the rotary plate 101 rotates. The upper rod 103 that pressurizes in cooperation with the upper plate 103 and an external force that is parallel to the rotation direction of the rotating disk 101 and opposite to the direction is applied in cooperation with the upper rod 103 and the lower rod 104 having the stepped portion. For molded product 100 obtained by pressing By applying to a shaped article separating means 128 to pay out the molded article 100 as sliding contact in the horizontal direction along the punch tip portion of the lower punch 104 above SL stepped surface該杵destination, the molded article separating means 128 2 is a rotary powder compression molding machine including a molded product discharging means 129 for discharging the molded product 100 having a step paid out by the above-mentioned to the outside of the turntable 101. Further, as shown in FIG. In FIG. 4, the powder supply process 130, the powder compression process 131, the molded product separation process 132, and the molded product discharge process 133 are sequentially performed by the rotation of the rotating disk 101.

  The turntable 101 is generally formed into a disk shape by casting iron or further spraying carbide onto the surface, and usually has a diameter of 200 to 1000 mm.

  A plurality of mortars 102 made of the same material as that of the turntable 101 or made of carbide, hardened iron, or the like are embedded in a portion adjacent to the periphery of the turntable 101 at predetermined intervals in the circumferential direction. The upper surface of each die 102 and the upper surface of the turntable 101 are flush with each other.

  A pair of upper and lower ridges (upper ridge 103 and lower ridge 104) made of the same material or the like are provided corresponding to each mortar 102. The lower punch 104 is inserted into the through hole of the mortar 102 so as to be slidable up and down from the lower side. Further, a step 100e required by the molded product 100 as shown in FIG. The step 104e as shown in FIG. Further, the upper punch 103 is inserted into the through hole of the mortar 102 so as to be slidable and detachable from above. Thus, by inserting the lower punch 104 into the through-hole of the mortar 102, a cavity 134 surrounded by the mortar 102 and the lower ridge 104 is formed.

  At this time, the tip (upper end portion) of the lower rod 104 forms the bottom of the cavity 134. The lower rod 104 moves with the rotation of the turntable 101, and is on a weight adjusting track 110, a separation height track portion 106, a discharge height track portion 108, a lowering track 111, and a guide track (not shown). It slides in the mounted state to obtain the axial movement necessary for the compression molding cycle. Specifically, in the powder supply process, the powder descends along the descending surface of the lowering trajectory 111 and rises to adjust the supply amount of the raw material powder by the weight adjusting trajectory 110. And in a powder compression process, it raises along the compression roll 113. FIG. Next, in the molded product separation step, the molded product 100 having a pressed step is raised along the separation height track portion 106 in order to pay out the molded product 100 from the tip of the lower rod 104. Thereafter, in the molded product discharge process, the molded product is lowered along the discharge height track portion 108.

  Further, the upper punch 103 press-molds the powder supplied into the cavity 134 by a powder supplier 114 (to be described later) in cooperation with the lower punch 104. The upper rod 103 also moves with the rotation of the turntable 101 like the lower rod 104, and moves on a predetermined track by the guide track to obtain the axial movement necessary for the compression molding cycle. Yes.

  At a powder supply position where the powder supply process 130 is performed, a powder supplier 114 is disposed as a powder supply means for supplying powder into a cavity 134 surrounded by the die 102 and the lower punch 104. The lower surface opening of the powder supplier 114 is in contact with the upper surface of the rotating disk 101, and the raw material powder is supplied into the cavity 134 of the die 102 when the die 102 passes through the powder supplier 114 facing the lower surface opening. It has become so. Here, in order to make the density of the raw material powder supplied into the die 102 uniform inside the powder supplier 114, a rotating stirring member (not shown) is provided as necessary.

  A weight adjusting track 110 with which the lower end of the lower rod 104 is slidably contacted is provided as a positioning means for determining the lower end position of the lower rod 104 at the powder supply position.

  Immediately before the weight adjustment track 110, a lowering track 111 is arranged. When the lower basket 104 descends according to the lowering track 111, the raw material powder in the powder feeder 114 is sucked into the cavity 134 and supplied, and immediately after that, the lower basket 104 slides on the inclined surface of the weight adjusting track 110. By moving up, surplus raw material powder is discharged into the powder feeder 114, and then the upper surface of the die 102 is slid at the lower end of the rear wall of the powder feeder 114 while the lower punch 104 slides on the horizontal surface of the weight adjusting track 110. As a result, the amount of powder supplied to the die 102 is weighed.

  That is, by changing the height of the weight adjustment track 110, the amount of powder supplied into the cavity 134 can be changed, in other words, the weight of the molded product 100 having a step to be manufactured can be changed. .

  At the compression molding position where the powder compression step 131 is performed, the compression rolls 112 and 113 are disposed above and below the rotating disk 101, respectively. The compression rolls 112, 113 move the upper and lower ridges 103, 104 passing between them in the axial direction so that the heel portions approach each other, and thus the upper and lower ridges 103, 104 can narrow the tip interval, thereby the cavity 134. It is provided to compress the powder inside. When the upper collar 103 passes through the compression molding position, the upper collar 103 is taken out from the cavity 134 and further rises along a guide track (not shown) to a height at which the upper collar 103 does not come into contact with a separation unit 105 described later.

  A molded product separation means 128 is installed at a molded product separation position where the molded product separation step 132 is performed. And the molded product 100 which has the level | step difference 100e obtained by pressurizing with the upper collar 103 and the lower collar 104 which has the step part 104e in the molded article isolation | separation means 128 after the upper collar 103 raises. Is shifted from the tip of the lower collar 104 and delivered to the upper surface of the rotating disc 101 by applying pressure in a direction that allows sliding out in a horizontal direction from the tip of the lower collar 104.

  A molded product discharge means 129 is installed at a molded product discharge position where the molded product discharge step 133 is performed. Then, in the molded product discharge separating means 129, the molded product 100 delivered to the upper surface of the turntable 101 is discharged from the turntable 101 to the outside by applying pressure in the direction of discharging to the outside of the turntable 101. .

Thus, in the rotary powder compressor according to the present invention, when the molded product 100 having the step 100e is continuously molded by installing the molded product separating means 128 and the molded product discharging means 129 at different positions, A stepped portion 104e as shown in FIG. 4 is formed at the tip portion of 104, but the molded product 100 abuts against the stepped portion 104e and does not cause chipping or breakage. it is possible along the front portion upward SL stepped surface該杵destination paid out by sliding contact with the molded article 100 in the horizontal direction, can be molded efficiently without causing defects in the molded product 100.

  Further, the molded product separating means 128 includes a separation unit 105 for discharging the molded product, a separation height track unit 106 for forming a track of the lower collar 104 when separating the molded product, and a separation height track unit.

  Here, the use of a scraper as the separating portion 105 allows the molded product 100 to be reliably paid out from the tip of the lower rod 104 by contact, and the molded product 100 is placed on approximately the same circumference on the upper surface of the turntable 101. It is preferable in that it can be paid out.

  The separation height track portion 106 is supported by a track lifting mechanism by the separation height adjusting portion 107, and is moved up and down by the operation of this track lifting mechanism. The orbit raising / lowering mechanism includes, for example, a raising / lowering driving device 116 composed of a servo motor, a handwheel handle, etc., a raising / lowering shaft 119 that supports the separation height orbiting portion 106 on the upper end portion and is moved up and down along a guide (not shown), and an inner peripheral gear portion. And a gear 122 provided by meshing the gear portion with a screw portion formed in the lower portion of the lifting shaft 119, and a drive gear 125 meshed with the outer peripheral gear portion of the gear 122 and rotated by the lifting drive device. It is configured.

  Thus, the molded product separating means 128 can adjust the height of the separating portion 105, and the separated height track portion 106 can be moved up and down by the operation of the track lifting mechanism, so that the molded product having the step 100e. 100 can be dispensed onto the turntable 101 from the tip of the lower lid 104 at an arbitrary height on the turntable 101. Therefore, when the molded product 100 is discharged from the tip of the lower rod 104 onto the turntable 101, the molded product 100 is raised from the upper surface of the rotary plate 101 to a position higher than the maximum height of the molded product 100 and discharged. The molded product 100 dropped on the upper surface of the turntable 101 by the pressure of the separation unit 105 does not cause a defect when hitting the separation unit 105, and the molded product 100 is the next step without being retained in the molded product separation step 132. It can be sent to the product discharge process 133.

  Further, the molded product discharge means 129 includes a discharge portion 127 for discharging the molded product, a discharge height track portion 108 for forming a lower rail for discharging the molded product, and a discharge height track portion. It is preferable to include a discharge height adjusting unit 109 for adjusting the height 108.

  For the discharge unit 127, a scraper, an air nozzle, or the like can be used. Then, the molded product 100 delivered to the upper surface of the turntable 101 in the molded product separation means is delivered out of the turntable 101 by the air pressure from the scraper or air nozzle of the discharge unit 127. Here, the use of the scraper as the discharge unit 127 is that the molded product 100 can be reliably paid out from the rotary disc 101 to the outside of the rotary disc 101, and the molded product 100 can be delivered to approximately the same position. preferable. Further, when a scraper is used as the discharge portion 127, the scraper is provided so as to obliquely intersect with the rotational trajectory of the die 102 and to be in slight sliding contact with the upper surface of the turntable 101, thereby forming the molded product 100. Is discharged from the top of the turntable 101 to the outside.

  The discharge height track portion 108 is supported by a track lifting mechanism by the discharge height adjusting portion 109, and is moved up and down by the operation of this track lifting mechanism. The orbit raising / lowering mechanism includes, for example, a raising / lowering driving device 117 composed of a servo motor, a handwheel handle, etc., a raising / lowering shaft 120 that supports the discharge height orbiting portion 108 on the upper end portion and is raised and lowered along a guide (not shown), and an inner peripheral gear portion. And a gear 123 provided by meshing the gear portion with a screw portion formed in the lower portion of the lifting shaft, and a drive gear 126 meshed with the outer peripheral gear portion of the gear and rotated by the lifting drive device 117.

  Thus, the molded product discharge means 129 of the rotary powder compression molding machine according to the present invention allows the molded product 100 having the step 100e to be turned on the rotary disk by the discharge height track portion 106 being vertically movable by the operation of the track lifting mechanism. When discharging outside 101, the tip position of the lower eyelid 104 can be set to an arbitrary height. Therefore, when the molded product 100 is paid out of the turntable 101, the molded product 100 can be moved from the tip of the lower guide 104 by lowering the tip of the lower guide 104 having the stepped portion 104 e from the upper surface of the turntable 101. It is possible to prevent the tip of the lower rod 104 from hitting the discharger 127 and damaging it while preventing the pinch by the discharger 127 from being lost.

  In the compression molding method of the rotary powder compression molding machine according to the present invention, the molded product 100 having the step 100e has the step 104e by the molded product separation means 128 and the molded product discharge means 129 as shown in FIG. It is paid out from the tip of the heel 104 and paid out to the turntable 101. That is, in the molded product separating means, the molded product 100 is taken out from the cavity 134 by the lower rod 104 sliding up the inclined surface of the separation height track portion 106 as shown in FIG. ) To a position higher than the maximum height of the molded product 100 from the upper surface of the turntable 101. Next, while the lower rod 104 slides on the horizontal surface of the separation height track portion 106, the separation portion 105 attached to a position higher than the maximum height of the molded product 100 from the upper surface of the rotating disk 101 as shown in FIG. Thus, the molded product 100 is displaced by applying pressure in a direction in which the molded product 100 can be slid in the horizontal direction from the tip of the lower rod 104 and discharged, and is discharged onto the upper surface of the turntable 101 as shown in FIG.
