Description

  The present invention relates to a receiving structure for a cup-shaped body on which a cup-shaped body is placed when DI processing is performed on the cup-shaped body at the time of manufacturing a DI can.

  A bottomed cylindrical DI can having a can body (wall) and a bottom (bottom) as a can that is filled and sealed with beverages and the like, and a disc that is wound around the open end of the DI can A two-piece can having a can-shaped can lid is known. A bottle can in which a cap is screwed to the opening end of the DI can is also well known.

  The DI can used in such a can body has a bottomed cylindrical shape by performing a cupping process (drawing process) and a DI process (drawing and squeezing process) on a disk-shaped blank punched out of a plate of aluminum alloy material. Formed.

  In the cupping step, the blank is subjected to cupping (drawing) to obtain a cup-shaped body that is a molding intermediate in the process of shifting from the blank to the DI can. In the DI step, a punch sleeve is fitted inside the cup-shaped body, and a plurality of dies are fitted outside, and the cup-shaped body is drawn and ironed between them. That is, DI (Drawing & Ironing) processing is performed on the cup-shaped body to obtain a DI can.

  In performing DI processing on a cup-shaped body, for example, an outer cylindrical body (cup-shaped body) conveying apparatus as described in Patent Document 1 below is used. The conveying device is rotated around a horizontal axis and is disposed below a pair of feed guides and a pair of feed guides formed so as to be able to hold cup-shaped bodies between the outer peripheral surfaces. And a receiving seat (cup stationer) on which the cup-shaped body held by the guide is placed.

  Specifically, the pair of feed guides are rotated in the opposite directions around the horizontal axis, and the cup-shaped body held between the recesses on the outer peripheral surface of each feed guide is accompanied by the rotation of the feed guides. One by one is moved downward and seated on the receiving seat. The upper surface of the receiving seat has a U-shaped cross section that is recessed downward, and the punch sleeve and the cup holder sleeve move forward from the horizontal direction with respect to the cup-shaped body placed on the upper surface. DI processing is performed between the sleeve and a plurality of dies (see, for example, Patent Document 2 below for details on DI processing).

Japanese Patent No. 2906306 JP 2007-216302 A

However, the conventional cup-shaped receiving seat has the following problems.
When performing DI processing on the cup-shaped body, positioning of the cup-shaped body placed on the receiving seat is important. That is, if the accuracy of the coaxiality (center alignment) between the center axis of the cup-shaped body (cup axis) and the center axis of the punch sleeve, cup holder sleeve and die (DI processing mold) is not secured, molding is performed. There is a risk that uneven thickness, partial elongation, etc. will occur in the subsequent DI can, which affects the performance of the DI can. However, conventionally, it has been difficult to ensure the positional accuracy of the cup-shaped body placed on the receiving seat.

  The present invention has been made in view of such circumstances, and can improve the positional accuracy of a cup-shaped body placed on a receiving seat, and is formed by DI processing of the cup-shaped body. An object of the present invention is to provide a receiving structure for a cup-shaped body that can stably improve the processing quality of a can.

  In one embodiment of the present invention, a pair of feed guides that are rotated around a horizontal axis and formed so as to be able to hold a cup-shaped body between the outer peripheral surfaces of each other are disposed below the pair of feed guides. A cup seat receiving structure on which a cup-shaped body held by the pair of feed guides is placed, and is orthogonal to each horizontal axis of the pair of feed guides. The receiving seat is movable relative to the pair of feed guides along an inter-axis direction connecting the horizontal axes.

  According to the cup-shaped receiving seat structure of the present invention, the receiving seat on which the cup-shaped body is placed is movable along the inter-axis direction with respect to the pair of feed guides. The center axis (cup axis) can be aligned with the center axis of the punch sleeve, cup holder sleeve and die (DI processing mold) used in the subsequent DI process.

In other words, the positional accuracy of the cup-shaped body placed on the receiving seat can be increased, the coaxiality between the cup-shaped body and the DI processing mold can be increased, and the processing accuracy of the molded DI can can be improved. it can. Specifically, it is possible to remarkably suppress the occurrence of uneven thickness, half-elongation and the like in the molded DI can, and to improve the processed quality of the DI can stably.
In the present invention, the “horizontal axis” refers to an axis extending in the horizontal direction, and includes an axis extending in a substantially horizontal direction.

  In the cup-shaped receiving seat structure, the receiving seat is disposed on a support base and is slidable along the inter-axis direction with respect to the support base. Includes a biasing member that biases the receiving seat toward the one side along the inter-axis direction with respect to the support base, and is screwed to the support base and the receiver with respect to the support base. It is preferable that a screw member capable of pressing the seat toward the other side along the inter-axis direction is provided.

In the above configuration, the receiving seat on which the cup-shaped body is placed is provided so as to be slidable in the inter-axis direction on the support base.
Specifically, the receiving seat is urged toward one side along the inter-axis direction by the urging member on the support base. Further, by turning the screw member, the receiving seat can be pressed against the support base toward the other side along the inter-axis direction, whereby the receiving seat slides on the support base.

That is, it is possible to easily adjust the position of the receiving seat in the inter-axis direction with respect to the support base depending on the screwing amount of the screw member.
Specifically, in order to adjust the position of the center axis (cup axis) of the cup-shaped body placed on the receiving seat with respect to the center axis of the DI processing mold, for example, fine adjustment of about 10 μm is required. Even with such fine adjustment, according to the above configuration of the present invention, the position of the receiving seat in the inter-axis direction can be confirmed while the screw member is screwed in, so that the adjustment work is easy. In addition, if the screwing amount is too large, the screwing amount of the screw member is returned (the screw is loosened), so that the position of the receiving seat is returned to the original position by the biasing force of the biasing member. The accuracy of position adjustment can be remarkably increased without complicating.

Here, in order to make it easier to understand the operational effects of the above-described configuration of the present invention, for example, unlike the above-described configuration, a long hole is formed in the support base in the axial direction, and a fixing screw inserted through the long hole is provided. The structure screwed to the receiving seat will be described.
In this case, first, the fixing screw is loosened, and the receiving seat is directly slid relative to the support base to adjust the position of the receiving seat. After adjusting the position of the receiving seat, tighten the fixing screw again to fix the position of the receiving seat. In addition, in order to stabilize the fixing state of the receiving seat, it is preferable that the number of long holes and fixing screws is more than one. Therefore, in this case, the skill of the operator is required for adjusting the position of the receiving seat, and there is a possibility that a slight positional deviation occurs when the fixing screw is tightened.

On the other hand, according to the above-described configuration of the present invention, since the position adjustment of the receiving seat is indirectly performed according to the screwing amount of the screw member, it is possible to suppress depending on the skill of the operator, and it is simple and fine. The position can be adjusted. In addition, since the screw member always presses the receiving seat while being screwed to the support base at the time of adjustment, the occurrence of a slight positional deviation is also suppressed in the receiving seat on the support base. .
Furthermore, even if there is only one screw member, the position can be adjusted with high accuracy, so that the structure can be simplified and the workability is good. In addition, it is preferable to arrange this screw member in the vicinity of the maintenance panel (opening of the outer wall close to the operator) of the DI processing apparatus, since the effect of improving workability becomes more remarkable.

  In the cup-shaped receiving seat structure, it is preferable that a vertical movement mechanism capable of moving the receiving seat in the vertical direction is provided for the pair of feed guides.

In this case, the receiving seat can move in the inter-axis direction (left-right direction) and the up-down direction with respect to the pair of feed guides. Therefore, the center axis (cup axis) of the cup-like body placed on the receiving seat can be reliably aligned with the center axis of the DI processing mold with higher accuracy.
This makes it possible to increase the positional accuracy of the cup-shaped body placed on the receiving seat, and to stably improve the processing quality of the DI can formed by DI processing of the cup-shaped body. The effect of the invention becomes even more remarkable.

  In the cup-shaped receiving seat structure, the vertical movement mechanism preferably includes an adjusting screw portion capable of adjusting a vertical position of the receiving seat with respect to the pair of feed guides.

  In this case, since the vertical movement mechanism includes the adjustment screw portion, the vertical position adjustment of the receiving seat with respect to the pair of feed guides can be stably performed with high accuracy by the screwing amount of the adjustment screw portion. .

  According to the receiving structure of the cup-shaped body of the present invention, the positional accuracy of the cup-shaped body placed on the receiving seat can be increased, and the processed quality of the DI can formed by performing DI processing on the cup-shaped body. Can be stably increased.

It is a perspective view which shows the receptacle structure of the cup-shaped body with which the DI processing apparatus which concerns on one Embodiment of this invention is equipped. It is a figure which expands and shows the principal part of FIG.

Hereinafter, a cup-shaped receiving structure 10 according to an embodiment of the present invention will be described with reference to the drawings.
The cup-shaped receiving seat structure 10 of the present embodiment is provided in a DI processing apparatus that performs DI processing on a cup-shaped body to form a DI can.

First, the DI can will be described.
The DI can is used for a can (a two-piece can or a bottle can) filled and sealed with contents such as a beverage. In the case of a two-piece can, the can body includes a bottomed cylindrical DI can and a disc-shaped can lid that is wound around the open end of the DI can. In the case of a bottle can, the can body includes a DI can (which has been subjected to die necking after DI processing) and a cap screwed onto the open end of the DI can. “DI” in the DI canister is an abbreviation for Drawing & Ironing.

  The DI can is formed into a bottomed cylindrical shape by performing a cupping process (drawing process) and a DI process (drawing and squeezing process) on a disk-shaped blank punched out of a plate made of an aluminum alloy material. Specifically, in the case of a two-piece can, for example, a DI can is manufactured through a plate material punching process, a cupping process, a DI process, a trimming process, a printing process, a painting process, a necking process, a bottom reforming process, and a flanging process in this order. The

  In the process of manufacturing the DI can, the blank is drawn (cupping) by a cupping press and formed into a cup-shaped body. That is, the cup-shaped body is a molded intermediate body produced in the process of shifting from a blank to a DI can in the cupping step. The cup-shaped body has a bottomed cylindrical shape in which the height of the peripheral wall (the length along the can axis direction) is smaller than that of the DI can and the diameter of the bottom wall is large.

Next, the DI processing apparatus will be described.
The DI processing apparatus is used in the DI process described above, and performs DI processing (drawing (redrawing) ironing) on the cup-shaped body to form a DI can.

  The DI processing apparatus includes a cup-shaped receiving base structure 10 shown in FIG. 1 and a single redrawing die having a through-hole having a circular cross section for redrawing the cup-like body, although not particularly shown. And a plurality of (for example, three) ironing dies (for example, ironing dies) having through-holes having a circular cross section arranged coaxially with the redrawing die, and coaxial with the ironing die, and passing through each ironing die A cylindrical or columnar punch sleeve that can be fitted into the hole and movable in the direction of the central axis of the die, and a cylindrical cup holder sleeve that fits outside the punch sleeve. ing.

As the above-described redraw die, ironing die, punch sleeve, and cup holder sleeve, for example, those described in Patent Document 2 (Japanese Patent Laid-Open No. 2007-216302) can be used. In this embodiment, the redraw die, the ironing die, the punch sleeve, and the cup holder sleeve may be referred to as a DI processing mold.
Each central axis of the DI processing mold is coaxial with each other and extends in the horizontal direction.

The DI processing to the cup-shaped body by the DI processing apparatus is performed as follows.
The cup-shaped body is placed on a receiving seat 3 of a cup-shaped receiving seat structure 10 to be described later. The cup-shaped body placed on the receiving seat 3 is disposed between the punch sleeve and the redraw die with the cup shaft (can shaft) extending in the horizontal direction and the opening directed to the punch sleeve. The

  The cup holder sleeve and the punch sleeve move forward relative to the cup-shaped body. Then, while the cup holder sleeve presses the bottom wall of the cup-shaped body against the end face of the re-drawing die and performs the cup pressing operation, the punch sleeve pushes the cup-shaped body into the through-hole of the re-drawing die and re-draws. Apply processing.

  By redrawing, a cup-shaped body having a smaller diameter and a longer length (height) along the cup axial direction than the cup-shaped body is formed. Subsequently, this cup-shaped body is pushed in with a punch sleeve and gradually ironed while passing through a plurality of ironing dies one after another. That is, the bottom walled cylindrical DI can is formed by squeezing the peripheral wall of the cup-like body and extending the peripheral wall to increase the peripheral wall height and reduce the wall thickness. This DI can is cold worked and hardened by squeezing the peripheral wall, and the strength is increased.

  In the DI can that has been ironed, the punch sleeve is further pushed forward to press the bottom portion (the portion that becomes the bottom of the can) against the bottom molding die, so that the bottom portion is formed in a dome shape.

Next, the cup seat receiving structure 10 will be described.
As shown in FIG. 1, the cup-shaped receiving seat structure 10 of the present embodiment is rotated around the horizontal axes O <b> 1 and O <b> 2 and is formed so as to be able to hold the cup-shaped body between the outer peripheral surfaces. A pair of feed guides 1 and 2 and a receiving seat (cup stationer) placed below the pair of feed guides 1 and 2 and on which a cup-shaped body held by the pair of feed guides 1 and 2 is placed 3 is provided.
The “horizontal axis” in the present embodiment refers to an axis extending in the horizontal direction, and includes an axis extending in a substantially horizontal direction.
In addition, the cup-shaped receiving seat structure 10 is orthogonal to the horizontal axes O1 and O2 of the pair of feed guides 1 and 2, and the inter-axis direction (the horizontal axes O1 and O2 are connected to each other). Opposite direction (left-right direction) A support base 4 that supports the receiving seat 3 in a slidable manner along C, and a vertical movement mechanism 5 that can move the receiving seat 3 in the up-down direction H via the support base 4. And.

  The feed guides 1 and 2 have a circular ring shape or a cylindrical shape, and in the example of this embodiment, are formed in a circular ring shape. In the example shown in FIG. 1, the feed guide 2 of the pair of feed guides 1 and 2 includes two ring bodies arranged at intervals in the horizontal axis O2 direction, and the feed guide 1 is horizontal. One ring body is provided between the two ring bodies along the direction of the axis O2. The horizontal axes O1 and O2 of the feed guides 1 and 2 extend in parallel to each other.

  The feed guides 1 and 2 are rotated around the horizontal axes O1 and O2 in opposite directions and in synchronization with each other. Although not specifically shown, the horizontal axes O1 and O2 of the feed guides 1 and 2 are arranged to extend in parallel to the central axis of the above-described DI processing mold.

In addition, a plurality of cup-shaped bodies with a cup shaft extending in parallel with the horizontal axes O1 and O2 are stacked in the vertical direction H above the feed guides 1 and 2. . Concave portions are formed on the outer peripheral surfaces of the feed guides 1 and 2, and only one cup-shaped body located at the lowermost end among a plurality of cup-shaped bodies can be held between the concave portions. is there.
As the feed guides 1 and 2 of the present embodiment, for example, those described in Patent Document 1 (Japanese Patent No. 2906306) can be used.

  When the feed guides 1 and 2 are rotated in the opposite directions around the horizontal axes O1 and O2, one cup-shaped body is provided between the recesses on the outer peripheral surfaces of the feed guides 1 and 2. Retained. The cup-shaped body held between the recesses is moved downward along with the rotation of the feed guides 1 and 2 and is seated one by one on the receiving seat 3. Specifically, one cup-shaped body is delivered to the receiving seat 3 when the feed guides 1 and 2 rotate once.

  As shown in FIGS. 1 and 2, the receiving seat 3 has a bottom wall and a pair of side walls that rise upward from both ends of the bottom wall in the axial direction C. The upper surface of the bottom wall in the receiving seat 3 and the inner surfaces of the pair of side walls have a shape corresponding to the outer peripheral surface of the cup-shaped body and are smoothly connected to each other to form one concave curved surface. Thus, a concave curved upper surface 3a on which the cup-shaped body is placed is formed in the receiving seat 3. Further, in a cross-sectional view perpendicular to the horizontal axes O1 and O2 (a front view seen from the direction of the horizontal axes O1 and O2), the upper surface 3a of the receiving seat 3 has a U shape that is recessed downward.

  The receiving seat 3 is disposed on a support table 4 described later, and is slidable along the inter-axis direction C with respect to the support table 4. The receiving seat 3 is movable along the inter-axis direction C with respect to the pair of feed guides 1 and 2.

  In FIG. 2, the support 4 includes a base 6 to which the receiving seat 3 is fixed, a bottom plate 7 that supports the base 6 so as to be slidable along the inter-axis direction C, and both end portions of the bottom plate 7 in the inter-axis direction C. A pair of side plates 8 (8A, 8B) that rises upward from the top, guide pins 9 that extend through the pedestal 6 in the inter-axis direction C, and are connected to the pair of side plates 8 at both ends, and the bottom plate 7 The urging member 11 that urges the pedestal 6 toward one side (left side in FIGS. 1 and 2) along the inter-axis direction C and the side plate 8 are screwed together, and the pedestal 6 is attached to the bottom plate 7. And a screw member 12 that can be pressed toward the other side (right side in FIGS. 1 and 2) along the inter-axis direction C.

  The pedestal 6 supports the receiving seat 3 and is integrally fixed to the receiving seat 3. The pedestal 6 is formed with a through hole penetrating the pedestal 6 along the inter-axis direction C, and a guide pin 9 is slidably fitted into the through hole. In the example of this embodiment, a pair of through holes are formed in the pedestal 6 at intervals in the horizontal axis O1 and O2 directions, and a pair of guide pins 9 are inserted through these through holes.

  The bottom plate 7 is formed to have a longer length in the inter-axis direction C than the base 6. The pedestal 6 placed on the bottom plate 7 and the receiving seat 3 fixed to the pedestal 6 are slidable along the inter-axis direction C with respect to the bottom plate 7. On the bottom surface of the bottom plate 7, a female screw portion 13 is provided that is screwed to a male screw portion (adjustment screw portion) 15 of the vertical movement mechanism 5 described later.

  A gap is provided between the pair of side plates 8 and each end face located at both ends along the interaxial direction C in the base 6. Of the pair of side plates 8, a side plate 8A located on one side in the inter-axis direction C is screwed with a screw member 12 that passes through the side plate 8A in the inter-axis direction C. In addition, a biasing member 11 is disposed between the side plate 8B located on the other side in the inter-axis direction C of the pair of side plates 8 and the end surface facing the other side in the inter-axis direction C in the base 6. ing.

  In the example of this embodiment, a compression coil spring that is elastically deformable along the inter-axis direction C is used as the biasing member 11, and a guide pin 9 is inserted into the biasing member 11. Yes. A pair of urging members 11 are provided corresponding to the pair of guide pins 9. The urging member 11 urges the pedestal 6 and the receiving seat 3 supported on the pedestal 6 toward the one side along the inter-axis direction C with respect to the bottom plate 7 of the support base 4.

  Moreover, in the example of this embodiment, the knurled screw by which the non-slip | skid process (knurling process) was given to the screw head is used as the screw member 12, A screw member is used, without using working tools, such as a driver. 12 can be screwed (the screwing amount of the screw member 12 is adjusted).

  The screw head of the screw member 12 is disposed on one side in the inter-axis direction C with respect to the side plate 8A. The tip of the screw shaft portion of the screw member 12 protrudes from the side plate 8A toward the other side in the inter-axis direction C, and is in contact with the end face of the base 6 facing one side in the inter-axis direction C. In the illustrated example, only one screw member 12 is provided, and the tip of the screw shaft portion of the screw member 12 has horizontal axes O1 and O2 among the end surfaces facing the one side in the inter-axis direction C of the base 6. It is made to contact | abut with respect to the center part along a direction.

The screw member 12 can press the base 6 and the receiving seat 3 supported on the base 6 toward the other side along the inter-axis direction C against the bottom plate 7 of the support base 4.
Specifically, the screw member 12 moves toward the other side in the inter-axis direction C with respect to the side plate 8A by turning the screw member 12 to the tightening side around the screw shaft. At this time, the tip of the screw shaft portion of the screw member 12 presses the pedestal 6 toward the other side in the interaxial direction C, and the pedestal 6 and the receiving seat 3 move on the bottom plate 7 to the other side in the interaxial direction C. Move towards. At this time, the urging member 11 is contracted (elastically deformed) in the inter-axis direction C.

  Further, by screwing the screw member 12 to the loose side around the screw shaft, the screw member 12 moves toward one side in the inter-axis direction C with respect to the side plate 8A. At this time, the pressure on the end surface of the base 6 facing the one side in the inter-axis direction C by the tip of the screw shaft portion of the screw member 12 is released, and the base 6 and the base 6 and the biasing force (restoring deformation force) of the biasing member 11 are released. The receiving seat 3 moves on the bottom plate 7 toward one side in the inter-axis direction C.

  Thus, by adjusting the screwing amount of the screw member 12, the base 6 and the receiving seat 3 can be moved along the inter-axis direction C with respect to the bottom plate 7 of the support base 4. More specifically, the receiving seat 3 can move along the inter-axis direction C with respect to the pair of feed guides 1 and 2 and the above-described DI processing mold by adjusting the screwing amount of the screw member 12.

The vertical movement mechanism 5 is capable of moving along the vertical direction H with respect to the pair of feed guides 1 and 2 and the above-described DI processing mold, along the support base 4 and the receiving seat 3 supported by the support base 4. It is configured.
As shown in FIGS. 1 and 2, the vertical movement mechanism 5 of the present embodiment includes a cylinder portion 14 that can move the support 4 and the receiving seat 3 in the vertical direction H with respect to the pair of feed guides 1 and 2. The male screw portion (adjustment screw portion) that can adjust the position of the support base 4 and the receiving seat 3 in the vertical direction H with respect to the pair of feed guides 1 and 2 at a pitch smaller than the stroke along the vertical direction H of the cylinder portion 14. 15).

The cylinder part 14 is, for example, an air cylinder, a hydraulic cylinder, an electric cylinder, or the like. The cylinder portion 14 includes a cylinder body and a rod that can move in the vertical direction H with respect to the cylinder body.
The rod protrudes upward from the cylinder body, and a support base 4 is connected to the tip (upper end) of the rod. In FIG. 1, the rod is in a state of being most protruded upward from the cylinder body (located at the top dead center), and in this state, the cup placed on the receiving seat 3 on the support base 4. DI processing is applied to the body.

  Further, from this state, the rod is movable downward with respect to the cylinder body. By the downward movement of the rod, the support 4 and the receiving seat 3 supported by the rod can be largely separated from the pair of feed guides 1 and 2. Thereby, for example, when a molding defect occurs during DI processing, the cup-shaped body can be easily taken out by moving the rod of the cylinder portion 14 downward.

  In FIG. 2, a male screw portion 15 is formed at the tip of the rod. The male screw portion 15 is screwed to the female screw portion 13 of the bottom plate 7 of the support base 4. By adjusting the screwing amount of the male screw part 15 with respect to the female screw part 13, the support base 4 and the receiving seat 3 can be moved along the vertical direction H with respect to the rod of the cylinder part 14. More specifically, the receiving seat 3 can move in the vertical direction H with respect to the pair of feed guides 1 and 2 and the above-described DI processing mold by adjusting the screwing amount of the male screw portion 15.

  A locking nut 16 is screwed onto the male threaded portion 15 of the rod. As described above, after adjusting the screwing amount of the male screw portion 15 with respect to the female screw portion 13, the locking screw nut 16 is tightened until it comes into contact with the female screw portion 13, whereby the female screw portion 13, the male screw portion 15, Are locked (fixed), and the positions of the support base 4 and the receiving seat 3 in the vertical direction H with respect to the rod of the cylinder portion 14 are stably maintained with high accuracy.

  According to the cup-shaped receiving seat structure 10 according to the present embodiment described above, the receiving seat 3 on which the cup-shaped body is placed is along the inter-axis direction C with respect to the pair of feed guides 1 and 2. Since it is movable, the center axis (cup axis) of this cup-shaped body is aligned with the center axis of the punch sleeve, cup holder sleeve and die (DI processing mold) used in the subsequent DI process. It becomes possible.

  That is, the positional accuracy of the cup-shaped body placed on the seat 3 can be increased, the coaxiality between the cup-shaped body and the DI processing mold is increased, and the processing accuracy of the molded DI can is improved. Can do. Specifically, it is possible to remarkably suppress the occurrence of uneven thickness, half-elongation and the like in the molded DI can, and to improve the processed quality of the DI can stably.

  In the present embodiment, the receiving seat 3 is disposed on the support base 4 and is slidable along the inter-axis direction C with respect to the support base 4. The support base 4 is screwed to the support base 4 and the biasing member 11 that biases the receiving seat 3 toward the one side along the inter-axis direction C with respect to the support base 4. On the other hand, a screw member 12 capable of pressing the receiving seat 3 toward the other side along the inter-axis direction C is provided. With this configuration, the following effects can be obtained.

  In other words, in the above configuration, the receiving seat 3 is urged toward the one side along the inter-axis direction C by the urging member 11 on the support base 4. Further, by screwing the screw member 12, the receiving seat 3 can be pressed against the support base 4 toward the other side along the inter-axis direction C, whereby the receiving seat 3 is moved on the support base 4. Move the slide.

That is, the position adjustment in the inter-axis direction C of the receiving seat 3 with respect to the support base 4 can be easily performed by the screwing amount of the screw member 12.
Specifically, in order to adjust the position of the center axis (cup axis) of the cup-shaped body placed on the receiving seat 3 with respect to the center axis of the DI processing mold, for example, fine adjustment of about 10 μm is required. . Even with such fine adjustment, according to the configuration of the present embodiment, the position of the receiving seat 3 in the inter-axis direction C can be confirmed while the screw member 12 is screwed in, so that the adjustment work is easy. is there. In addition, when the screwing amount is too large, the position of the receiving seat 3 is returned to the original position by the biasing force of the biasing member 11 by returning the screwing amount of the screw member 12 (releasing the screw). The accuracy of position adjustment can be significantly increased without complicating the position adjustment work.

Here, in order to make it easy to understand the operational effects of the above-described configuration of the present embodiment, although not particularly illustrated, for example, unlike the above-described configuration, a long hole is formed in the support base 4 in the inter-axis direction C. A configuration in which the fixing screw inserted through the hole is screwed to the receiving seat 3 will be described.
In this case, first, the fixing screw is loosened, and the receiving seat 3 is directly slid relative to the support base 4 to adjust the position of the receiving seat 3. When the position of the receiving seat 3 is adjusted, the fixing screw is tightened again to fix the position of the receiving seat 3. In addition, in order to stabilize the fixing state of the receiving seat 3, it is preferable that the number of long holes and fixing screws is more than one. Therefore, in this case, the skill of the operator is required for the position adjustment of the receiving seat 3, and there is a possibility that a slight positional deviation occurs when the fixing screw is tightened.

On the other hand, according to the above-described configuration described in the present embodiment, the position adjustment of the receiving seat 3 is indirectly performed according to the screwing amount of the screw member 12, so that it does not depend on the skill of the operator. Can be adjusted easily and precisely. In addition, since the screw member 12 always presses the receiving seat 3 via the base 6 while being screwed to the supporting base 4 at the time of adjustment, the position of the receiving base 3 on the supporting base 4 is extremely small. The occurrence of deviation is also suppressed.
Furthermore, as in this embodiment, even if there is only one screw member 12, position adjustment can be performed with high accuracy, so that the structure can be simplified and workability is good. Although not particularly illustrated, when the screw member 12 is disposed near the maintenance panel (opening of the outer wall close to the operator) of the DI processing apparatus, the effect of improving workability becomes more remarkable. Therefore, it is preferable.

Moreover, in this embodiment, since the vertical movement mechanism 5 which can move the receiving seat 3 to the up-down direction H with respect to a pair of feed guides 1 and 2 is provided, there exists the following effect.
That is, in this case, the receiving seat 3 is movable in the inter-axis direction (left-right direction) C and the up-down direction H with respect to the pair of feed guides 1, 2. Therefore, the center axis (cup axis) of the cup-shaped body placed on the receiving seat 3 can be reliably aligned with the center axis of the DI processing mold with higher accuracy.
Thereby, the positional accuracy of the cup-shaped body placed on the receiving seat 3 can be increased, and the processing quality of the DI can formed by performing DI processing on the cup-shaped body can be stably increased. The operational effects of this embodiment become even more remarkable.

In the present embodiment, the vertical movement mechanism 5 includes a male screw part (adjustment screw part) 15 that can adjust the position of the receiving seat 3 in the vertical direction H with respect to the pair of feed guides 1 and 2. Has an effect.
That is, in this case, since the vertical movement mechanism 5 includes the male screw portion 15, the position adjustment in the vertical direction H of the receiving seat 3 with respect to the pair of feed guides 1 and 2 is performed with respect to the male screw portion 13 of the support base 4. Depending on the screwing amount of the screw part 15, it can be performed stably with high accuracy.

In this embodiment, a guide pin 9 extending along the inter-axis direction C is inserted into the base 6 to which the receiving seat 3 is fixed, and the guide pin 9 extends in the extending direction (that is, the inter-axis direction C). The receiving seat 3 is slidable along. Therefore, the receiving seat 3 can be accurately slid along the inter-axis direction C, and the position adjustment accuracy can be further improved.
Further, since the guide pin 9 is inserted into the urging member 11, the performance of the urging member 11 can be stabilized, and loss can be prevented.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, in the above-described embodiment, the supporting base 4 that supports the receiving seat 3 is biased with the biasing member 11 that biases the receiving seat 3 toward one side along the inter-axis direction C with respect to the supporting base 4. The screw member 12 that is screwed to the base 4 and can press the receiving seat 3 toward the other side along the inter-axis direction C with respect to the support base 4 is provided. It is not something.
That is, the receiving seat 3 may be slidable along the inter-axis direction C with respect to the support base 4 by a configuration other than the above configuration. Furthermore, the seat 3 can be moved along the inter-axis direction C with respect to the pair of feed guides 1 and 2 and the DI processing mold by a configuration other than the support base 4 (that is, without providing the support base 4). It may be said.

In the above-described embodiment, the receiving seat 3 is fixed to the pedestal 6 of the support base 4. However, the embodiment is not limited thereto. For example, the pedestal 6 is formed integrally with the receiving seat 3. May be. In this case, the bottom portion (the portion corresponding to the pedestal 6) of the receiving seat 3 is directly placed on the bottom plate 7, and the receiving seat 3 slides on the bottom plate 7 along the axial direction C. A guide pin 9 is inserted into the bottom of the receiving seat 3. Further, the screw member 12 directly presses the end surface of the receiving seat 3 facing the one side in the inter-axis direction C, and the biasing member 11 directly presses the end surface facing the other side of the receiving shaft 3 in the inter-axis direction C. Energize.
Further, the guide pin 9 may not be provided.

Further, in the above-described embodiment, the urging member 11 is a compression coil spring, and the urging member 11 includes the side plate 8B positioned on the other side in the inter-axis direction C of the pair of side plates 8 and the shaft 6 between the shafts. Although it is arranged between the end face facing the other side in the direction C, it is not limited to this. That is, for example, the urging member 11 may be a tension coil spring. In this case, the urging member 11 has a side plate 8A located on one side in the inter-axis direction C of the pair of side plates 8 and a shaft 6 on the pedestal 6. And an end face facing one side of the inter-direction C.
Further, the biasing member 11 may be formed of an elastic material such as a leaf spring or rubber other than the coil spring described above.

In the above-described embodiment, the vertical movement mechanism 5 includes the cylinder portion 14 and the male screw portion (adjustment screw portion) 15. However, the present invention is not limited to this.
For example, instead of the male screw portion 15 of the vertical movement mechanism 5, a female screw portion (adjustment screw portion) may be provided. In this case, a male screw portion is provided instead of the female screw portion 13 of the support base 4, and the female screw portion (adjustment screw portion) is screwed. Further, the vertical movement mechanism 5 may include, for example, an actuator unit or the like instead of the cylinder unit 14.
The vertical movement mechanism 5 includes only the adjustment screw portion 15 and does not need to include the cylinder portion 14. However, when the vertical movement mechanism 5 includes the cylinder portion 14 as in the above-described embodiment, it is preferable because the cup-shaped body can be easily removed when a molding defect or the like occurs during DI processing.

  In addition, in the range which does not deviate from the meaning of this invention, you may combine each structure (component) demonstrated by the above-mentioned embodiment, a modification, and a remark etc., addition of a structure, omission, substitution, others It can be changed.
