However, many of these metals cannot be processed by plastic metal processing. The plastic properties are poor under the working conditions. Therefore, it is possible to deform low plasticity metals. Apparatus for plastic deformation of metals under high hydrostatic pressures has been developed. such a device In the prior art (SO1AI47321B), a hydromechanical forming apparatus for articles is disclosed. This device is arranged in a coaxial relationship and is connected via a hydraulic distributor. , in communication with a source of working fluid and a reservoir adapted to receive discharged working fluid. A speed increaser with a low pressure chamber and a hydraulic distributor supply the working fluid source and also the discharge. Has a rod end in communication with a reservoir adapted to receive working fluid to increase speed The device is arranged on the side of the rod, which accommodates the blank and receives the die. A container with a chamber that becomes filled with plasticizing liquid during the blank forming operation.

The hydraulic cylinder receives the source of working fluid and also receives the discharged working fluid through the hydraulic line. a deceleration device having a low-pressure chamber in communication with the reservoir, which is now in communication with the vessel; It is interposed between the rod of the speed device and communicates with the chamber of the container during the blank forming operation.

研究の結果、上述した装置では、作動サイクル当たり全エネルギー消費量の約６ ０％が、可塑化液体でブランクを塑性変形させるのに必要とされる圧力を容器チ ャンバ内に生み出しに、又ブランク成形作業中、液体が、容器チャンバから減速 装置の高圧チャンバに押し入れられるので、可塑化液体の流れによる抵抗に打ち 勝つのに必要とされることがわかった。換言すれば１、可塑化液体が、ブランク 成形作業中、多量のエネルギーを作り、この工程の終了まで、この液体が動力集 中担体を構成する。可塑化液体が、容器チャンバから減速装置の高圧チャンバに 押し入れられ、減速装置のロッド及びピストンは移動して、初期位置をとり可塑 化液体によって作られたエネルギーは、減速装置の低圧チャンバ内及び油圧管路 内の作動流体に伝達され、それにより減速装置の低圧チャンバは、作動流体源及 び排出作動流体を受け入れるようになったリザーバと連通ずる。油圧管路内の作 動流体は、この油圧管路の絞り弁を通過するので、そのエネルギーは、不可逆的 に失われ、エネルギーを失った作動流体１は、それを受け入れるようになったリ ザーバに排出される。その結果、ブランクの塑性変形中に作られた可塑化液体エ ネルギーは、装置の次の作動サイクルで使用されることなく、油圧管路の絞り弁 で取り返し不能に浪費される。これが、物品の油圧機械式成形の既知の装置の効 率が悪い主な理由のひとつである。As a result of research, it has been found that for the device described above, the total energy consumption per operating cycle is approximately 6 0% is the pressure required to plastically deform the blank with the plasticizing liquid in the container chamber. During the blank forming operation, liquid decelerates from the container chamber. It is forced into the high-pressure chamber of the device, overcoming the resistance of the plasticizing liquid flow. I found out what I needed to do to win. In other words, 1, the plasticizing liquid is the blank During the molding process, a large amount of energy is created and this liquid is used to collect power until the end of the process. It constitutes a medium carrier. Plasticizing liquid is transferred from the container chamber to the high pressure chamber of the decelerator. The rod and piston of the reduction gear move and assume the initial position and plasticize. The energy created by the liquid is transferred to the low-pressure chamber of the speed reducer and to the hydraulic lines. the low pressure chamber of the reduction gear is connected to the working fluid source and and communicates with a reservoir adapted to receive the pumping and draining working fluid. Work inside hydraulic pipes As the dynamic fluid passes through the throttle valve in this hydraulic line, its energy is irreversibly The working fluid 1, which has lost its energy due to is discharged into the reservoir. As a result, the plasticizing liquid effluent created during the plastic deformation of the blank The energy is stored in the hydraulic line throttle valve without being used in the next operating cycle of the equipment. is irretrievably wasted. This explains the effectiveness of known devices for hydromechanical forming of articles. This is one of the main reasons for the poor rate.

このような物品の油圧機械的成形装置では、ブランク成形作業中、可塑化液体を 容器チャンバから減速装置の高圧チャンバに押し入れ、さらに又減速装置のロッ ドとピストンの初期位置への移動によって、可塑化液体によって蓄えられたエネ ルギーが、減速装置の低圧チャンバ内及び逆止弁と減速装置の低圧チャンバとの 間に構成された油圧管路の部分内の作動流体に伝達される。Hydromechanical forming equipment for such articles uses a plasticizing liquid during the blank forming operation. from the container chamber into the high-pressure chamber of the speed reducer, and then into the lock of the speed reducer. The movement of the cylinder and piston to their initial positions releases the energy stored by the plasticizing liquid. energy in the low pressure chamber of the reduction gear and between the check valve and the low pressure chamber of the reduction gear. and to the working fluid within the portion of the hydraulic conduit constructed between them.

The working fluid that fills the hydraulic line between the low-pressure chamber and the , is also communicated to the working fluid filling the low pressure chamber itself. As a result, this The working fluid is used to move the stones and rods of the reduction gear and to perform the blank forming operation. Hold it in place. In other words, the energy stored by the plasticizing liquid It makes it possible to prevent irreparable waste and expense, and also serves two purposes: 1.

上述した装置は、以下の仕方で運転される。The device described above operates in the following manner.
最初の作動サイクル開始前に、ブランクをダイ２２の上に置き、容器２０のチャ ンバ２１を可塑化液体で満たす。作動流体源１２を増速装置ｌの低圧チャンバ７ と連通させ、パワーシリンダー２のロッド端部チャンバ１８を排出した作動流体 用リザーバ１３と連通させる位置に油圧分配器１１を切り換える。そのとき、作 動流体は、作動流体源１２から油圧分配器１１を介して増速装置ｌの低圧チャン バ７まで油圧管路１０に沿って供給される。増速装置１の低圧チャンバ７内の作 動流体によって及ぼされる圧力の作用により、ロッド６を有するピストン５は移 動し、その結果、ロッド６は、増速装置１の高圧チャンバ８内及びパワーシリン ダー２のピストンチャンバ１７内の作動流体を圧縮する。増速装置１の高圧チャ ンバ８内及びパワーシリンダー２のピストンチャンバ１７内の作動流体によって 及ぼされる圧力は、パワーシリンダー２のロッド１６を有するピストン１５を移 動させ、その移動は、ダイ２２を有する容器２ｏに伝達され、ブランクは、ポン チ３４に向かってダイ２２の中へ置かれる。ピストン１５が移動すると、ロッド 端部チャンバ１８の容積は減り、これにより、チャンバ１８を満たしていた作動 流体を油圧管路１９に沿って油圧分配器１１を介して、排出作動流体用リザーバ １３に流出させる。同時に、作動流体は、逆止弁を経て油圧管路２９に沿って、 減速装置３の低圧チャンバ２６に供給される。減速装置３の低圧チャンバ２６内 の作動流体によって及ぼされる圧力によって、ロッド２５を有するピストン２４ は、ポンチ３４の方に動かされる。物品の油圧機械的成形用装置の部品及び油圧 駆動内の作動流体の上述した移動の結果、ポンチ３４は、容器２０のチャンバ２ １に入り、それによってチャンバ２１をシールし、チャンバ２１の容積を減じる 。Before starting the first working cycle, a blank is placed on the die 22 and the chamber of the container 20 is opened. Fill the chamber 21 with plasticizing liquid. The working fluid source 12 is connected to the low pressure chamber 7 of the speed increaser l. the working fluid which discharged the rod end chamber 18 of the power cylinder 2; The hydraulic distributor 11 is switched to a position where it communicates with the reservoir 13. At that time, The dynamic fluid is passed from the working fluid source 12 through the hydraulic distributor 11 to the low pressure chamber of the speed increaser l. It is supplied along a hydraulic line 10 to the bar 7. Operation inside the low pressure chamber 7 of the speed increaser 1 Under the action of the pressure exerted by the moving fluid, the piston 5 with the rod 6 is moved. As a result, the rod 6 moves inside the high pressure chamber 8 of the speed increaser 1 and the power cylinder. The working fluid in the piston chamber 17 of the cylinder 2 is compressed. High pressure cha of speed increaser 1 by the working fluid in the chamber 8 and the piston chamber 17 of the power cylinder 2. The pressure exerted displaces the piston 15 with the rod 16 of the power cylinder 2. The movement is transmitted to the container 2o having the die 22, and the blank is moved by the pump. is placed into the die 22 toward the chip 34. When the piston 15 moves, the rod The volume of end chamber 18 is reduced, thereby reducing the volume of actuation that filled chamber 18. The fluid is routed along a hydraulic line 19 via a hydraulic distributor 11 to a reservoir for draining working fluid. 13. At the same time, the working fluid passes through the check valve and along the hydraulic line 29. It is supplied to the low pressure chamber 26 of the speed reduction device 3. Inside the low pressure chamber 26 of the speed reducer 3 Due to the pressure exerted by the working fluid of the piston 24 with the rod 25 is moved towards the punch 34. Parts of equipment for hydromechanical forming of articles and hydraulics As a result of the above-described movement of the working fluid within the drive, the punch 34 moves into the chamber 2 of the container 20. 1, thereby sealing chamber 21 and reducing the volume of chamber 21. .
その結果、容器２０のチャンバ２１内の可塑化液体によって及ぼされる圧力は、 ブランクを構成する金属の降伏点を越え、ついにはダイ２２の成形及びポンチ３ ４の形体によって確定的に形づ（られるブランクの成形の変化を引き起こす。容 器２２のチャンバ２１の容積が減すると、可塑化液体は、容器２２のチャンバ２ １からポンチ３４に形成された流路３５を通って減速装置３の高圧チャンバ２７ に押し出される。これにより、減速装置３の高圧チャンバ２７の容積の増加をも たらし、ロッド２５を有するピストン２４が移動してポンチ３４から遠ざけられ る。可塑化液体によって蓄えられたエネルギーは、減速装置３の低圧チャンバ２ ６及び油圧管路２９の部分３３を満たす作動流体に伝達され、エネルギーの蓄積 が、アキュムレータ３１により起こる。逆止弁３０は、作動流体が減速装置３の 低圧チャンバ・２６から排出作動流体用リザーバ１３に流出するのを防止し、そ れにより、アキュムレータ３１が可塑化液体のエネルギーを蓄えるのを可能にす ることに注目する必要がある。そのうえで、作動流体源１２をパワーシリンダー ２のロッド端部チャンバ１８と連通させ、増速装置１の低圧チャンバ７を、排出 作動流体用リザーバ１３と連通させる位置に油圧分配器１１を切り換える。その 結果、ピストン５及び増速装置ｌのロッド６及びパワーシリンダー２のロッド１ ６を有するピストン１５は、移動してポンチ３４から遠ざけられる。ポンチ３４ は、容器２２のチャンバ２１を去り、その結果シールを果たさなくなり、完成物 品が容器２２のチャンバ２１から取り出される。かくして、装置の第１作動サイ クルは終了する。その後の作動サイクルの各々は、第１作動サイクルで説明した 工程に従って行われ、唯−異なる点は、アキュムレータ３１によって蓄えられた エネルギーが、逆止弁３０と減速装置３の低圧チャンバ２６との間に構成される 油圧管路２９の部分３３を満たす作動流体に伝達され、又減速装置３の低圧チャ ンバ２６を満たす流体にも伝達されることである。その結果、作動流体は移動し 、次のブランクの形成が起こるような位置に、減速装置３のロッド２５及びピス トン２４を保持する。換言すれば、可塑化液体のエネルギーの取り返しのつかな い浪費を防止することが可能になる。か（して、このエネルギーは、２つの目的 のために即ち、１番目には、ピストン２４及び減速装置３のロッド２５を、ブラ ンク成形位置に戻すために、２番目にはブランク成形作業中、容器２２のチャン バ２１からの可塑化液体の流れに抵抗を与えるために、本発明の装置の引き続く 作動サイクルに利用される。可塑化液体のエネルギーの貯蔵及び引き続く再使用 は、装置の運転用のエネルギー消費を低減し、それにより効率を上げる。As a result, the pressure exerted by the plasticizing liquid in chamber 21 of container 20 is The yield point of the metal constituting the blank is exceeded, and the die 22 is finally formed and the punch 3 This causes a change in the shaping of the blank which is definitively shaped by the features in Figure 4. When the volume of chamber 21 of container 22 is reduced, the plasticizing liquid is transferred to chamber 2 of container 22. 1 to the high-pressure chamber 27 of the speed reducer 3 through a flow path 35 formed in the punch 34. is pushed out. This also increases the volume of the high pressure chamber 27 of the reduction gear device 3. Then, the piston 24 with the rod 25 is moved away from the punch 34. Ru. The energy stored by the plasticizing liquid is transferred to the low pressure chamber 2 of the deceleration device 3. 6 and the working fluid filling the section 33 of the hydraulic conduit 29, the energy storage occurs due to the accumulator 31. The check valve 30 is configured so that the working fluid of the speed reducer 3 is Prevents leakage from the low pressure chamber 26 into the drained working fluid reservoir 13 and This allows the accumulator 31 to store the energy of the plasticizing liquid. It is necessary to pay attention to this. Then, connect the working fluid source 12 to the power cylinder. 2, and the low pressure chamber 7 of the speed increaser 1 is connected to the rod end chamber 18 of the speed increaser 1. The hydraulic distributor 11 is switched to a position where it communicates with the working fluid reservoir 13. the As a result, the piston 5, the rod 6 of the speed increaser l, and the rod 1 of the power cylinder 2 The piston 15 with 6 is moved away from the punch 34. punch 34 leaves the chamber 21 of the container 22, resulting in failure to seal and the finished product The item is removed from chamber 21 of container 22. Thus, the first operating cycle of the device Kuru ends. Each of the subsequent actuation cycles is as described in the first actuation cycle. The process is carried out according to the procedure, the only difference being that the storage by the accumulator 31 is Energy is configured between the check valve 30 and the low pressure chamber 26 of the speed reducer 3 It is transmitted to the working fluid filling the section 33 of the hydraulic line 29 and also to the low pressure chamfer of the reduction gear 3. It is also transmitted to the fluid filling the chamber 26. As a result, the working fluid moves , the rod 25 and the piston of the reduction gear 3 are placed in such a position that the formation of the next blank occurs. Holds 24 tons. In other words, the energy of the plasticizing liquid is irreversible. This makes it possible to prevent unnecessary waste. (So, this energy has two purposes. Firstly, the piston 24 and the rod 25 of the reduction gear 3 are During the blank forming operation, the chamber 22 is moved back to the blank forming position. In order to provide resistance to the flow of plasticizing liquid from the bar 21, the subsequent Used for operating cycles. Energy storage and subsequent reuse of plasticizing liquids reduces energy consumption for the operation of the equipment, thereby increasing efficiency.
工業上の利用性 複雑な外部形体を有する物品の油圧機械的成形に要求されるエネルギーの評価を 行う研究が行われてきており、この複雑な外部形体は、可塑化液体の圧力を増大 するために、物品の油、圧機械的成形成の上述した装置によって、及び装置の油 圧駆動によりエネルギー損失を完全に回収する対策をする上述した工程の使用に よって、鉄道車両のアクセルボックス等のスピルトダイの使用を必要とする。Industrial applicability Evaluate the energy required for hydromechanical forming of articles with complex external geometries. Research has been conducted to demonstrate that this complex external shape increases the pressure of the plasticizing fluid. By means of the above-mentioned equipment for the oil of the article, the piezo-mechanical forming, and the oil of the equipment For the use of the above-mentioned process, which takes measures to completely recover energy losses through pressure drive. Therefore, it is necessary to use a spill die such as an accelerator box of a railway vehicle.
