せるための装置に関する。That is, the present invention sequentially supplies semi-finished materials that are aligned and supplied to a multi-stage heading forming machine one by one in a required posture to the front of the heading die of the heading stage in synchronization with the heading operation of the forming machine. The present invention relates to a device for

かって進退するラムで、夫々保持されている。By the way, there is no need to give examples of multi-stage forging machines that are configured to form bolts, nuts, and various other parts by forging supplied materials step by step. , a plurality of sets of heading stages each consisting of a pair of opposing heading dies and a heading punch are arranged in parallel at equal intervals, and the heading die of each heading stage is a die block fixed to the machine body side, and the heading punch is also Each is held by a ram that advances and retreats toward the dive block.

が備えられている。In addition, this multi-stage heading forming machine usually uses a long bar-shaped material and cuts it inside the machine.
As exemplified in Japanese Patent No. 23697 and Japanese Patent No. 57-49299, the die block side before the first heading stage serves as a supply stage for a fixed length material, and a long material is fed out and cut into predetermined lengths. Tiles and cutters are provided for cutting.

得るようになっている。In addition, in this multi-stage heading forming machine, in order to sequentially transfer the fixed length material cut at the material supply stage from the first heading stage to the final heading stage, for example,
As shown in Publication No. 84 and Publication No. 57-48294, a material transfer mechanism called a transfer chuck or the like, which is equipped with the same number of chucks as forging dies, suspends only each chuck to the front surface of the die block. In addition, when it is necessary to reverse the direction of the material between specific heading stages, only the chuck responsible for transferring the material between the legs can rotate 180 degrees during the transfer. It looks like this.
よって、このような多段式圧造成形機によれば、その圧
造段数に応じて、かなり複雑な形状の製品をも、棒状の
長尺素材から一貫して圧造成形できることになる。特に
近年では、圧造段数が増える傾向にあり、５〜６段のも
のも珍しくない。従って、より一層複雑な形状の製品で
も、その−貫した圧造成形が可能になってきている。Therefore, according to such a multi-stage heading molding machine, depending on the number of heading stages, even a product having a fairly complicated shape can be consistently pressed from a long rod-shaped material. Particularly in recent years, there has been a tendency for the number of heading stages to increase, and 5 to 6 stages are not uncommon. Therefore, even products with even more complex shapes can be forged through the entire shape.
ところが現今に至っては、上記したような圧造段数の増
加に伴う複雑な製品の圧造可能化に刺激されて、従来で
は他の例えば切削加工に頼るか或いは該加工を併用する
の他ないとされていたような更に複雑な形状の製品まで
をも、圧造加工のみで済ますことが可能化できないか、
という新たな要望が出され始めた。However, to date, as the number of heading stages has increased as described above, it has become possible to forge complex products, and in the past, the only option was to rely on other processes, such as cutting, or to use these processes in combination. Is it possible to make products with even more complex shapes, such as those shown above, by just heading processing?
New demands have begun to emerge.
然るに上記の多段式圧造成形機は、当然のこと乍ら、圧
造段数が増すに連れて高価となり、且つ大形化する。従
って圧造段数を更に増加させることは、理論的には充分
に可能であるが、現実的ではない。However, the above-mentioned multi-stage heading forming machine naturally becomes more expensive and larger as the number of heading stages increases. Therefore, although it is theoretically possible to further increase the number of heading stages, it is not practical.
また、現在量も普及している圧造段数が２〜３段の圧造
成形機で、５〜６段のものに依るのと同等の製品を圧造
可能化できないが、との要望も出されている。Additionally, there have been requests that the currently popular forging machines with 2 to 3 stages cannot produce the same products as those using 5 to 6 stages. .
よって、圧造段数を増やすことなく、これらの要望に応
えるためには、現状の多段式圧造成形機へ、予め成る程
度まで成形された半成素材を棒状の長尺素材に替えて供
給し、これを引き続いて該成形機で圧造加工するの他な
い。Therefore, in order to meet these demands without increasing the number of heading stages, a semi-finished material that has been formed to a certain extent can be supplied to the current multi-stage heading machine instead of a rod-shaped long material. There is no other choice but to proceed with the forging process using the molding machine.
然し乍ら前記した素材供給段は、このような半成素材の
供給に適当でなく、といって該供給段をその供給に適す
るよう改変することは、後における長尺素材の供給に不
都合を来すので、好ましくない。従って、かかる半成素
材の供給は、既存の素材供給段を利用しないで、圧造段
へ直接的に行わせるのが望ましい。However, the material supply stage described above is not suitable for supplying such semi-finished materials, and modifying the supply stage to be suitable for supplying such a material would cause inconvenience in later supply of long materials. Therefore, it is not desirable. Therefore, it is desirable to supply such semi-finished material directly to the heading stage without using the existing material supply stage.
但し、このような半成素材の圧造段への供給には、種々
の条件を伴う。即ちこの供給は、圧造ダイを保持したダ
イプロ・ツクと圧造パンチを保持したラムとの間の狭い
空間内で、該ラムの圧造動作に同期させて、半成素材を
圧造パンチで圧造ダイ内へ圧入させ易い姿勢に整え乍ら
、順次に１個ずつ行われねばならない。However, various conditions are involved in supplying such a semi-finished material to the heading stage. In other words, this supply is carried out in a narrow space between a die pro-tsuku that holds a forging die and a ram that holds a forging punch, and in synchronization with the forging operation of the ram, the semi-finished material is fed into the forging die by the forging punch. It must be done one by one in sequence while preparing the position for easy press-fitting.
そこで、本発明が解決すべき第一の問題点は、多段式圧
造成形機への半成素材の供給を、如何にすれば上記の条
件を満たし乍ら実現させ得るかにあり、第二の問題点は
、そのような半成素材の供給を、既製の多段式圧造成形
機に対しても、如何にすれば既存の素材供給段を残した
ままで実現させ得るかにある。Therefore, the first problem to be solved by the present invention is how to supply a semi-finished material to a multi-stage heading molding machine while satisfying the above conditions. The problem lies in how to supply such a semi-finished material to a ready-made multi-stage forging machine while leaving the existing material supply stages intact.
換言すると、本発明の目的は、公知の多段式圧造成形機
につき、棒状の長尺素材が使用されることを前提とし乍

めんとする点にある。In other words, the object of the present invention is to develop a known multi-stage heading molding machine, which is based on the assumption that long rod-shaped materials are used, but can also easily supply semi-finished materials if necessary. There is a point to be concerned about.
かかる問題点の解決、従って目的達成のために、本発明
者等はまず次の如く考察した。In order to solve these problems and thus achieve the objective, the inventors first considered the following.
即ち、通常の多段式圧造成形機に装備されてい−′ る

その圧造段とこれの前段との間を往復するチャックが、
不要となる。なお素材移送機構が備える複数個の各チャ
ックは、いずれも個々にユニット化されており、従って
個別的な着脱交換が可能である。That is, the material transfer mechanism installed in a normal multi-stage heading forming machine operates in synchronization with the heading operation of the ram holding the group of heading punches, and connects the first chuck of the ram to the material supply stage. It is made to reciprocate between the first heading stage and the fixed length material cut from the rod-shaped long material in the former stage to be transferred to the front of the heading die in the latter stage. Therefore, this first yank becomes unnecessary when a semi-finished material is to be directly supplied to the first heading stage instead of a rod-shaped elongated material. In addition, semi-finished materials can be used as secondary materials.
When trying to supply to the forging stage or subsequent stages,
A chuck that reciprocates between the heading stage and the preceding stage,
No longer needed. Note that each of the plurality of chucks included in the material transfer mechanism is individually unitized, and therefore can be individually attached and detached.
よって、半成素材を圧造段へ直接的に供給するための装
置は、上記のチャックと置換し１厚るような寸法形状に
、ユニット化しておけば良い。そしてこの装置に、半成
素材の供給源として、公知な撮動式ないし他方式の整列
機を併用すれば、該装置へ半成素材を整然と並べて送り
込むことができ、且つその素材に方向性があっても、こ
れの方向を上記整列機で自動的に揃えることができる。Therefore, the device for directly supplying the semi-finished material to the heading stage may be made into a unit having a size and shape that replaces the chuck described above and is thicker by one inch. If this device is used in conjunction with a known photographic type or other sorting machine as a supply source for semi-finished materials, it is possible to feed the semi-finished materials into the device in an orderly manner, and the materials have no directionality. Even if there are any, their directions can be automatically aligned using the above-mentioned alignment machine.
また通常の場合、圧造ダイの前へ供給される素材は、ラ

される。然し乍ら上記の整列機自体には、半成素材を１
個ずつ間歇送りする機能および送出し端で該素材を圧造
ダイ内へ圧入させ易い姿勢に整える機能がない。Further, normally, one piece of material is supplied in front of the heading die for each reciprocation of the ram, and the supplied material is press-fitted into the heading die by the advancing heading punch. However, the above-mentioned alignment machine itself has one semi-finished material.
There is no function to feed the material intermittently one by one and a function to arrange the material at the feeding end into a position that makes it easy to press-fit the material into the forging die.
よって上記のユニット化される供給装置には、半成素材
についての間歇供給機能と姿勢修正機能とを持たせる必
要があり、且つそれらの両機能を発揮させる駆動源には
、素材移送機構の往復動作を利用すれば良い。Therefore, it is necessary for the above-mentioned unitized supply device to have an intermittent supply function and a posture correction function for the semi-finished material, and the drive source that performs both of these functions includes a reciprocating mechanism for the material transfer mechanism. You can use motion.
このような考察に基づき、本発明の技術的手段は次のよ
うに構成されている。Based on such consideration, the technical means of the present invention is configured as follows.
まず、素材移送機構のチャックと置換されることを前提

姿勢をラムの往復方向へ修正する転回ブロックが、これ
を収容するケースと共に備えられる。First, on the premise that it will be replaced with the chuck of the material transfer mechanism, the entire device is made into a unitized, vertically elongated form. This device has a vertical guide tube through which the semi-finished material is slid down in the longitudinal direction, the upper end of which is connected via a suitable flexible tube or the like to a source of semi-finished material, for example a known alignment machine. be done. Further, near the lower end of the guide tube, a pair of upper and lower restraining claws are provided to prevent the semi-finished material from sliding down one by one to the lower end. A turning block for correcting the rotation direction of the ram in the reciprocating direction of the ram is provided together with a case that houses the turning block.

が設けられている。The drive system that operates these stopper claws and turning blocks consists of a drive gear that alternately receives rotational force in both forward and reverse directions from the reciprocating motion of the material transfer mechanism, a drive shaft that transmits the rotational force, and a drive shaft that transmits the rotational force. It consists of an intermittent feed cam that operates the stop pawl, and a transmission gear that causes the rotation block to interlock with the drive shaft. Note that the case of the turning block described above is provided with a hole through which a forging punch on the ram side can pass.
このように構成された本発明の技術的手段では、ユニッ

付けられる。従ってこの供給装置全体は、ラムの圧造動
作に同期した素材移送機構の往復動作に基づいて、この
場合には圧造成形機の素材供給段と第１圧造段との間を
往復する。In the technical means of the present invention constructed in this way, the entire unitized feeding device is attached to the material transfer mechanism of a multi-stage heading forming machine, replacing, for example, the first chuck thereof. Therefore, the entire feeding device reciprocates between the material supply stage and the first heading stage of the heading forming machine in this case based on the reciprocating movement of the material transfer mechanism in synchronization with the heading action of the ram.
尤も、多段式圧造成形機に既存の素材供給段は、この場
合には棒状の長尺素材を使用しないため不要であり、従
って該供給段のカッターは、上記供給装置が第１チヤツ
クと置換されるときには、これとの競合を避けるために
も、取り外してお（方が望ましい。However, the existing material supply stage of the multi-stage heading forming machine is unnecessary because no rod-shaped long material is used in this case, and therefore, the cutter of the supply stage is replaced with the first chuck by the above-mentioned supply device. It is preferable to remove it when using it to avoid conflicts with it.
また、この供給装置における案内管の上端を半成素材供
給源へ接続する可撓管等は、後者から前者への半成素材
の送込みを、当該装置の往復動作に妨げられることなく
可能ならしめるものとする。In addition, the flexible tube, etc. that connects the upper end of the guide tube in this feeding device to the semi-finished material supply source should be used if it is possible to feed the semi-finished material from the latter to the former without being hindered by the reciprocating movement of the device. shall be closed.
一方、素材移送機構の往復動作は、上記供給装置の駆動
軸へ交互に正転および逆転方向の回転力を与えて、案内
管が備えた上下一対の制止爪および転回ブロックを夫々
作動させる。On the other hand, the reciprocating operation of the material transfer mechanism applies rotational force in the forward and reverse directions alternately to the drive shaft of the supply device, thereby respectively operating a pair of upper and lower stopper claws and a rotation block provided on the guide tube.
そこで両割止爪については、この供給装置全体が半成素

にしておく。Therefore, with regard to both splitting claws, when the entire supply device is moved to the front stage of the heading stage where the semi-finished material is to be supplied, only the lowest semi-finished material in the guide tube is delivered to the lower end of the pipe. In this situation, the second and subsequent semi-finished materials placed higher than that group are prevented from sliding down, and the entire apparatus moves to the heading stage where the semi-finished materials are to be supplied. The groups of semi-finished materials after the second one are sequentially slid down one by one to the bottom, and the semi-finished materials that have reached the lowest level are prevented from sliding down any further. Regarding the turning block, when the entire device is moved to the front stage of the heading stage to which the semi-finished material is to be supplied, it slides down (1) (the turning block is oriented in the direction of receiving the semi-finished material, and the device is When the whole is moved toward the heading stage to which the semi-finished material is to be supplied, it is oriented in the reciprocating direction of the ram.
各制止爪および転回ブロックと素材移送機構との関係を
上記のように規定しておくと、この供給装置に半成素材

されることになる。If the relationship between each stop pawl, turning block, and material transfer mechanism is defined as described above, the semi-finished material fed from the semi-finished material supply source to this feeding device will be one piece per reciprocation of the ram. After the material is fed to the front of the heading die of the heading stage to be fed at a rate of It will be forged at the same time.
よって上記したような本発明によれば、棒状の長尺素材

製品の圧造加工のみによる成形を可能ならしめ得る。Therefore, according to the present invention as described above, a semi-finished material that has been formed to a predetermined degree can be If necessary, the material can be replaced with a long material and easily supplied in a desired posture in an orderly manner. Therefore, the number of heading stages is 5.
~Even with a multi-stage heading molding machine that can reach as many as 6 stages, the number of heading stages is still insufficient.It is possible to make it possible to form products by only heading processing, even if the number of heading stages is insufficient. Even with a heading machine that only has 2 or 3 stages, by dividing the total required number of heading processes into 2 or several steps, it is possible to perform only the heading process for complex products, in the same way as using a heading machine with many heading stages. It can be made possible to mold by.
また本発明は、半成素材供給のための装置全体を、多段

させることができる。Further, in the present invention, the entire apparatus for supplying semi-finished materials is made into a unit so that it can be replaced with a chuck of a material transfer mechanism installed in a multi-stage heading forming machine. Therefore, according to the present invention, in a narrow space between a die block holding a forging die and a ram holding a forging bunch, semi-finished materials are sequentially produced one by one in synchronization with the forging operation of the ram. can be supplied individually.

る。However, since such a semi-finished material can be supplied directly to the desired heading stage, there is no need to particularly modify the existing material supply stage of the multi-stage heading machine, and therefore the semi-finished material can be supplied directly to the desired heading stage. If the material is not to be fed, simply by replacing the original chuck with the unitized feeding device according to the present invention, it is possible to return to the conventional form in which a long material is used. That is, the present invention can be applied to a ready-made multi-stage forging machine to supply semi-finished materials without making it impossible to supply long materials.

Immediately after entering the interior, when the movable frame 12 of the material transfer mechanism B moves back to the right, the entire supply device C is similarly moved to the right. At this time, the intermediate frame 14 parallel to the movable frame 12 also moves back to the right, but the stroke length is smaller than the former. Such a difference in stroke length between both frames 12.14 causes a relative movement of one set of drive gears 31, 32, with one gear 31 remaining stationary and the other gear 32 moving to the right. , since the former fixed by the bracket throat 33 does not rotate, the latter is rotated counterclockwise in FIG. This rotation is caused by a pair of intermediate gears 34.3

b ”, first press this lower stopper claw 23.
b is rotated counterclockwise in FIG. 6 by the elasticity of the spring 24b, and its tip begins to enter the guide tube 19. Subsequently, the lower stopper claw 23b receives the elasticity of the spring 24b and further rotates, and when the corner piece 23b' of the lower stopper claw 23b butts against the corner piece 23a' of the upper stopper claw, the lower stopper claw 23b is thereafter pushed by this corner piece 23b'. The upper stopper claw 23a is also rotated counterclockwise in FIG.
Start to retreat from within. That is, when the movable frame 12 of the material transfer mechanism B heads toward the end of the backward stroke, the tip of the lower stopper claw 23b first enters the guide tube 19 as shown in FIG. 8, and then reaches the end. By this time, the tip of the upper stopper claw 23a has retreated from the inside of the guide tube 19, as shown in FIG. Therefore, each of the semi-finished materials D2+D from the second piece onwards, which had been prevented from sliding down by the upper stopper claw 23a,
:b... is 1 in sequence at the end of the above backward stroke.
It slides down one by one to the bottom, and this time the receiver is stopped by the lower stopper claw 23b.

を採るように修正される。On the other hand, when the drive shaft 30 rotates as described above, the rotation is transmitted to the shaft 29 via the bevel gears 37 and 38, causing the rotation block 27 to rotate clockwise in FIGS. . Therefore, inside the receiving hole 28 of this block, the semi-finished material DI, which was initially in a vertical position as shown in FIG.
As the movable frame 12 of the material transfer mechanism B approaches the end of the backward stroke, it gradually tilts as shown in FIG.
By the time it reaches its end, it has been corrected to take a horizontal position as shown in FIG.

爪２３ｂが先端を後退させる方向に回動する。In this way, after one semi-finished material DI is supplied to the first heading stage and subjected to the heading process, when the ram 5 retreats, the movable frame 12 of the material transfer mechanism B now moves forward to the left. Then, move the supply device C to the left. Then, since the drive shaft 30 is rotated in the opposite direction to that during the above-mentioned backward movement, the respective stop claws 23a, 23b of the guide tube 19 and the turning block 27 at the lower end rotate in the completely opposite order to the above-mentioned backward movement. to operate in the opposite direction. Therefore, 2 in the guide tube 19
The lower stopper claw 23b, which holds the subsequent semi-finished materials D2+03+... as shown in Fig. 9, is still maintained in that position, but during the forward stroke, the upper stopper claw 23a rotates in the direction in which the tip enters into the guide tube 19, pressurizes the third semi-finished material D3 by the elasticity of the spring 24a, and then, by the time it reaches the end of the forward stroke, the lower stop The claw 23b rotates in the direction of retracting the tip.
