An object of the present invention is to provide an automatic powder feeding device in a manufacturing device.
以下、本考案を第４図以下を参照して説明する。Hereinafter, the present invention will be explained with reference to FIG. 4 and subsequent figures.
図面中１１はテーブルであり、このテーブル１１の上面
に摺動可能に給粉器１２が設けである。In the drawing, 11 is a table, and a powder feeder 12 is slidably provided on the upper surface of the table 11.
この給粉器１２は油圧シリンダ１３の作動によりプレス
機Ａ内に出入可能になっている。This powder feeder 12 can be moved in and out of the press A by the operation of a hydraulic cylinder 13.
給粉器１２は摺動板１７を備えており、この摺動板１７
には円形孔１４が形威しである。The powder feeder 12 is equipped with a sliding plate 17, and this sliding plate 17
The circular hole 14 is a prominent feature.
この円形孔１４の中心には円板１５が回転可能に設けて
あり、円板１５の周囲には環状の網目構造１６が取付け
である。A disk 15 is rotatably provided at the center of the circular hole 14, and an annular mesh structure 16 is attached around the disk 15.
摺動板１７には支持部材１８を介してモータ１９が固設
してあり、モータ１９の出力側は減速機２０を介して円
板１５に連結してあり、これらで回転駆動機構Ｂを構成
している。A motor 19 is fixed to the sliding plate 17 via a support member 18, and the output side of the motor 19 is connected to the disc 15 via a reducer 20, which constitutes a rotational drive mechanism B. are doing.
また、摺動板１７には支持部材２１を介してホッパー２
２が設けである。Further, the sliding plate 17 is provided with a hopper 2 via a support member 21.
2 is a provision.
図面中２３は粉末タンクである。23 in the drawing is a powder tank.
しかして、給粉器１２が後退したとき、粉末タンク２３
からホッパー２２内に一定量の粉末が供給される。Therefore, when the powder feeder 12 is retracted, the powder tank 23
A fixed amount of powder is fed into the hopper 22 from the hopper 22 .
この場合、モータ１９の駆動により減速機２０を介して
円板１５が回転し網目構造１６が回転している。In this case, the disk 15 is rotated by the drive of the motor 19 via the reducer 20, and the mesh structure 16 is rotated.
したがって、常時回転している網目構造１６内に全周に
わたってホッパー２２から粉末が供給される。Therefore, powder is supplied from the hopper 22 over the entire circumference of the mesh structure 16, which is constantly rotating.
油圧シリンダ１３の作動により給粉器１２が前進し網目
構造１６がプレス機Ａの下部金型２４の環状溝２５すな
わち下パンチｌｂ上に位置したとき前進運動が止まる。The powder feeder 12 moves forward by the operation of the hydraulic cylinder 13, and when the mesh structure 16 is positioned above the annular groove 25 of the lower mold 24 of the press A, that is, the lower punch lb, the forward movement stops.
下部金型２４は第６図に示すように芯金１ａ、下パンチ
ｌｂ、ダイス１Ｃの３部分より構成され下パンチ１ｂは
自動的に上下動することができる。As shown in FIG. 6, the lower mold 24 is composed of three parts: a core metal 1a, a lower punch lb, and a die 1C, and the lower punch 1b can move up and down automatically.
給粉器１２が前進中は芯金１ａ、下パンチ１ｂ１ダイス
１ｃの上面高さが同一になっており、網目構造１６が下
パンチ１ｂの上まで前進して停止したとき環状溝２５の
深さが所定深さになるように下パンチ１ｂが降下する。While the powder feeder 12 is moving forward, the top surface heights of the core bar 1a, lower punch 1b, and die 1c are the same, and when the mesh structure 16 moves forward to the top of the lower punch 1b and stops, the depth of the annular groove 25 The lower punch 1b descends so that the depth reaches a predetermined depth.
同時に回転している網目構造１６の粉末が環状溝２５に
供給される。At the same time, the powder of the rotating network structure 16 is fed into the annular groove 25 .
供給後、給粉器１２が後退し上部金型２６が降下して圧
