Description

Technical Field

[0001] The present invention relates to a forming device for forming a material. Background Art

[0002] As a molding device, there is known a press molding device that molds a metal plate using an upper mold and a lower mold. As disclosed in Japanese Patent Application Laid-Open No. 2008-132719, the molding device molds the material by, for example, using a pressurizing device to press a slider to which an upper mold is fixed toward a lower mold in one direction. Such a molding device is used, for example, to mold cylindrical cans such as can bodies of bottles.

[0003] In addition, in a molding device, there is also known a technique for guiding the movement of a slider in one direction by providing a cylindrical guide post and a cylindrical linear bushing guided in one direction along the guide post.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2008-132719

[0005] However, in the molding device, in the structure in which the slider is guided to move by the guide post and the linear bushing, it is difficult to increase the moving speed of the slider due to the friction resistance generated when the guide post and the linear bushing slide. In this regard, the existing molding device has a productivity problem.

[0006] In addition, the guide column and the linear bushing are easily displaced by the load generated during press molding, and there is a problem of durability.

[0007] Furthermore, since the guide post and the linear bush overlap each other for a long time in one direction, it may be difficult to disassemble and assemble the guide post and the linear bush during maintenance of the molding device. Summary of the invention

[0008] Therefore, an object of the present invention is to provide a molding device capable of improving productivity, durability, and maintainability.

[0009] According to one aspect of the present invention, the forming device 1 comprises: four pillars extending in one direction, arranged at the four corners of a rectangular area, and having a first side surface and a second side surface; a first slider arranged in the rectangular area and pressed by a pressure device; a second slider pressed by at least one of the pressure device and the first slider; a first guide rail arranged on each of the first side surfaces and extending in the one direction; a second guide rail arranged on each of the second side surfaces and extending in the one direction; a first guide member movably arranged on each of the first guide rails along the first guide rails and fixed to the first slider; a second guide member movably arranged on each of the second guide rails along the second guide rails and fixed to the second slider.

[0010] According to the present invention, it is possible to provide a molding device capable of improving productivity, durability, and maintainability. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Below, use Figures 1 to 4 The structure of a molding device 1 according to one embodiment of the present invention will be described.

[0050] Figure 1 1 is a top view showing the structure of a molding device 1 according to an embodiment of the present invention. Figure 2 is a side view showing the structure of the molding device 1 in partial cross section, Figure 3 It is a plan view showing the structure of the molding device 1 with some parts omitted. Figure 4 It is a plan view showing the structure of the rail guide 13 .

[0051] like Figure 1 as well as Figure 2 As shown, the molding device 1 includes, for example, a frame 11, a slider 12, a guide rail guide 13, a pressurizing device 14, an auxiliary pressurizing device 15, an upper mold 16, a lower mold 17, a conveying device 18, and a control device 19. The molding device 1 is a device that uses the upper mold 16 and the lower mold 17 to apply pressure to the material to mold the material. The molding device 1 is configured, for example, to place the upper mold 16 above the lower mold 17 in the direction of gravity so that pressure can be applied to the material in the direction of gravity. The molding device 1 is used, for example, in a process of molding a can body of a bottle can.

[0052] For example, the frame 11 includes a first base 21 provided on the installation surface where the molding device 1 is installed, four pillars 22 provided on the first base 21, and a second base where the pressurizing device 14 is installed. Note that the second base can be configured to be capable of installing the pressurizing device 14, and its detailed description is omitted.

[0053] The first base 21 fixes four pillars 22 in a predetermined arrangement. The first base 21 has a main surface on which the four pillars 22 are fixed, for example, in a rectangular shape.

[0054] The support pillars 22 are extended in one direction. In the present embodiment, the support pillars 22 are extended in one direction along the gravity direction. Four support pillars 22 are arranged at the four corners of the rectangular area. In other words, the four support pillars 22 are arranged in a so-called four-column discrete four-corner arrangement relationship, and the area where the outer surfaces of adjacent support pillars 22 are connected to each other is configured into a rectangular shape. That is, the four support pillars 22 are respectively opposite to each other in two directions orthogonal to the other two support pillars 22, and the two opposing support pillars 22 are arranged at a predetermined interval. For example, the four support pillars 22 are arranged at the four corners of the first base 21.

[0055] The support 22 has a plurality of side surfaces, two of which constitute a first side surface 22a extending in one direction and a second side surface 22b extending in one direction and intersecting the first side surface 22a in the plane direction. The support 22 is formed, for example, in a shape in which the first side surface 22a and the second side surface 22b are orthogonal to each other. As a specific example, the horizontal cross section of the support 22 is formed in a rectangular shape, and two adjacent side surfaces of the four side surfaces constitute the first side surface 22a and the second side surface 22b, respectively.

[0056] Each support 22 is arranged so that the first side surfaces 22a and the second side surfaces 22b of two adjacent support 22 face each other. Here, the interval between the first side surfaces 22a of each support 22 is larger than the interval between the second side surfaces 22b of each support 22.

[0057] The slider 12 has an upper mold 16 fixed to a portion thereof. The slider 12 is pressed by the pressurizing device 14 and moves in one direction by being guided by the rail guide 13. The slider 12 is pressed by the pressurizing device 14 to move the fixed upper mold 16 toward the lower mold 17.

[0058] The slider 12 includes, for example, a first slider 31 and a second slider 32. The first slider 31 and the second slider 32 are respectively connected to parts of different rail guides 13. Such a slider 12 is configured so that the first slider 31 and the second slider 32 can move independently of each other. The slider 12 is configured so that, for example, the first slider 31 pressed by the pressurizing device 14 can press the second slider 32 in the moving direction.

[0059] The first slider 31 is configured to be able to abut against the second slider 32 in the gravity direction. The first slider 31 abuts against the second slider 32 by being pressed in one direction by the pressure device 14, and presses the abutted second slider 32 in one direction. In addition, the first slider 31 is configured to be connectable to a portion of the rail guide 13. The first slider 31 is arranged on the inner side of four pillars 22 arranged in four directions. For example, the first slider 31 is arranged on the inner side of a rectangular area in which the four pillars 22 are arranged. Here, the inner side of the four pillars includes an area between the opposite first side surfaces 22a and the second side surfaces 22b. Specifically, the first slider 31 is located between the opposite first side surfaces 22a of the four pillars 22, and is located closer to the inner side than the opposite second side surfaces 22b.

[0060] As a specific example, the first slider 31 includes a top plate portion 41 that can abut against the second slider 32, a pair of side plates 42 provided on the top plate portion 41, and a plurality of first connecting members 43 fixed to each of the pair of side plates. In addition, the first slider 31 forms a space in which the second slider 32 can be connected to a portion of the rail guide 13.

[0061] The top plate portion 41 is formed so as to be contactable with the second slider 32 from above. For example, the top plate portion 41 is formed in a flat plate shape whose main surface in the horizontal direction is rectangular according to the pressurizing device 14. In addition, the top plate portion 41 has a plurality of holes 41a connected from the upper surface to the lower surface. The plurality of holes 41a are formed so as to allow a connection portion 92 described later of the pressurizing device 14 to pass therethrough.

[0062] One of the pair of side plates 42 is provided along one side of the lower surface of the top plate 41, and the other is provided on the other side opposite to the one side. In addition, the main surfaces of the pair of side plates 42 are opposite to each other in the direction in which the second side surfaces 22b of the pillars 22 are opposite to each other. A plurality of first connecting members 43 are fixed to the side plates 42.

[0063] The first connection member 43 is connected to a part of the rail guide 13. The first connection member 43 is provided at a position close to the first side surface 22a of the support column 22 on the main surface of the side plate portion 42. In addition, the same number of first connection members 43 as the number of guide members 62 described later provided in each rail guide 13 are provided for one rail guide 13. In the present embodiment, two first connection members 43 are provided for one rail guide 13.

[0064] The second slider 32 is arranged inside the first slider 31, and is configured to be pressed by at least one of the pressurizing device 14 and the first slider 31. With respect to the arrangement of the first slider 31, the second slider 32 is arranged in a direction pressed by the first slider 31 pressed by the pressurizing device 14. For example, the second slider 32 is arranged below the first slider 31 in the pressing direction. In addition, the second slider 32 is configured to fix a part of the guide rail guide 13. In addition, the second slider 32 is configured to fix the upper mold 16 at the lower part.

[0065] As a specific example, Figures 1 to 3 As shown, the second slide block 32 has a retaining portion 51 and a second connecting component 52 .

[0066] The holding portion 51 is configured to hold the upper mold 16. The holding portion 51 is disposed inside the first slider 31. Specifically, the holding portion 51 is located below the top plate 41 in the moving direction and inside the pair of side plates 42 in a direction perpendicular to the moving direction.

[0067] The second connection member 52 is connected to a part of the rail guide 13. The second connection member 52 is provided on the outer surface of the holding portion 51 at a position close to the second side surface 22b of the support 22. In addition, the same number of second connection members 52 as the guide member 62 described later provided in each rail guide 13 is provided for one rail guide 13. In the present embodiment, two second connection members 52 are provided for one third rail guide 13.

[0068] like Figure 1 as well as Figure 2 As shown, the guide rail guide 13 has a guide rail 61 and a guide member 62. The guide rail guide 13 is configured such that the guide rail 61 is extended in one direction and the guide member 62 can move along the extension direction of the guide rail 61. In addition, the guide rail guide 13 restricts the guide member 62 from moving in a direction orthogonal to the extension direction of the guide rail 61. The guide rail guide 13 is a so-called linear guide, such as an LM guide (registered trademark). The guide rail guide 13 guides the movement of the first slider 31 or the second slider 32 connected via the first connecting member 43 or the second connecting member 52.

[0069] The guide rail 61 is formed to be able to guide the movement of the guide member 62 in one direction. As a specific example, Figure 4 As shown, the guide rail 61 has a plurality of abutment surfaces 71 extending in one direction and abutting against the guide member 62 in a direction orthogonal to the extending direction. In addition, the guide rail 61 is fixed to the support column 22 by a plurality of bolts installed along the extending direction.

[0070] The plurality of abutment surfaces 71 abut against a portion of the guide member 62 in two directions perpendicular to and intersecting the extending direction of the guide rail 61. For example, four of the plurality of abutment surfaces 71 are provided obliquely relative to the first side surface 22a and the second side surface 22b of the support 22 in the direction perpendicular to the extending direction of the guide rail 61.

[0071] The guide rails 61 are respectively provided on the first side surface 22a and the second side surface 22b of each support 22. Note that for ease of description, the guide rail 61 provided on the first side surface 22a is referred to as the first guide rail 61a and the guide rail 61 provided on the second side surface 22b is referred to as the second guide rail 61b.

[0072] The first guide rail 61a is provided on the first side surface 22a of each support column. The first guide rail 61a extends in the same direction as the extending direction of the support column 22.

[0073] The second guide rail 61b is provided on the second side surface 22b of each support column 22. The second guide rail 61b extends in the same direction as the extending direction of the support column 22. That is, the second guide rail 61b extends in the same direction as the first guide rail 61a, and is arranged in a direction that is orthogonal to the extending direction of the first guide rail 61a and is rotated 90 degrees from the first guide rail 61a.

[0074] The guide 62 includes a guide body 81 and a plurality of rotating bodies 82 incorporated in the guide body 81. The guide 62 is provided on each guide rail 61, and is configured to be movable along the extending direction of the guide rail 61 and to be restricted from moving in a direction orthogonal to the extending direction of the guide rail 61.

[0075] The guide body 81 is configured to abut each rotating body 82 against each abutting surface 71 of the guide rail 61. The guide body 81 is formed, for example, in a block shape having a notch matching the outer shape of the guide rail 61 including a pair of recesses formed in the guide rail 61. In addition, the guide body 81 is connected to the first connecting member 43 or the second connecting member 52.

[0076] The rotating body 82 is inserted into the guide body 81 and is disposed in contact with the surface of the guide rail 61. In addition, the rotating body 82 is disposed at multiple locations and is configured to prevent the guide body 81 from falling off the guide rail 61. Specifically, Figure 4 As shown, the plurality of rolling elements 82 are disposed opposite to each other in two directions perpendicular to the extending direction so as to be able to contact the contact surfaces 71 of the guide rail 61. For example, the rolling elements 82 are balls or rollers.

[0077] The guide members 62 are provided on the first guide rail 61a and the second guide rail 61b, respectively. Note that for ease of description, the guide member 62 provided on the first guide rail 61a is referred to as the first guide member 62a, and the guide member 62 provided on the second guide rail 61b is referred to as the second guide member 62b.

[0078] The first guide member 62a is provided on each first guide rail 61a in a manner movable along the first guide rail 61a. In addition, each first guide member 62a is fixed to the first slider 31 via the first connecting member 43. In addition, for example, a plurality of first guide members 62a are provided for one first guide rail 61a. In the present embodiment, two first guide members 62a are provided for one first guide rail 61a, one is fixed to the upper end portion of the first slider 31, and the other is fixed to the lower end portion of the first slider 31.

[0079] The second guide 62b is provided on each second guide rail 61b in a manner that it can move along the second guide rail 61b. That is, the second guide 62b is arranged in a direction that is orthogonal to the extending direction of the guide rail 61 in a direction in which the first guide 62a is rotated 90 degrees. In addition, each second guide 62b is fixed to the second slider 32 via the second connecting member 52. In addition, for example, a plurality of second guides 62b are provided for one second guide rail 61b. In the present embodiment, two second guides 62b are provided for one second guide rail 61b, one is fixed to the upper end of the second slider 32, and the other is fixed to the lower end of the second slider 32.

[0080] The pressurizing device 14 is configured to be able to press the slider 12 in the moving direction. In the present embodiment, the pressurizing device 14 presses the slider 12 in the gravity direction. In addition, the pressurizing device 14 is configured to be able to press the first slider 31 and the second slider 32 separately, for example. The pressurizing device 14 has, for example, a press part 91 and a connecting part 92. The pressurizing device 14 is, for example, a so-called crank mechanism press machine.

[0081] The pressurizing part 91 is configured to pressurize the connecting part 92 in one direction. As a specific example, the pressurizing part 91 rotates the crankshaft using a power source to reciprocate the crank in one direction. The pressurizing part 91 transmits the reciprocating movement of the crank to the connecting part 92 .

[0082] The connection portion 92 is formed, for example, in a rectangular column shape extending in the moving direction of the slider 12. One end of the connection portion 92 is connected to the pressurizing portion 91, and the other end is fixed to the slider 12. For example, a pair of connection portions 92 is fixed to the upper surface of the first slider 31. In addition, the connection portion 92 passes through two holes 41a provided in the first slider 31, and a pair of connection portions 92 is fixed to the second slider 32. The connection portion 92 reciprocates in one direction using the pressurizing portion 91, thereby transmitting pressure in one direction to the first slider 31 and the second slider 32.

[0083] The pressurizing device 14 is composed of, for example, a crank that transmits power to the connecting portion 92 fixed to the first slider 31 and a crank that transmits power to the connecting portion 92 fixed to the second slider 32, and a phase difference is set between the reciprocating motions of each other. Such a pressurizing device 14 causes a phase difference between the reciprocating motions of the first slider 31 and the second slider 32.

[0084] The auxiliary pressurizing device 15 is configured to press the first slider 31 and the second slider 32 in the moving direction. In the present embodiment, the auxiliary pressurizing device 15 is configured to press the first slider 31 and the second slider 32 upward in the gravity direction. The auxiliary pressurizing device 15 includes, for example, a cylinder and a supply unit for supplying air to the cylinder. Figure 1 As shown, the auxiliary pressurizing devices 15 are respectively provided on the first slider 31 and the second slider 32. Here, a plurality of auxiliary pressurizing devices 15 are provided symmetrically about the central axis of the first slider 31 or the second slider 32. The plurality of auxiliary pressurizing devices 15 provided on the first slider 31 are configured, for example, so that a pressing force at least equal to the weight of the first slider 31 can be applied to the first slider 31 by using the air pressure supplied to the cylinder. The plurality of auxiliary pressurizing devices 15 provided on the second slider 32 are configured, for example, so that a pressing force at least equal to the weight of the second slider 32 and the upper mold 16 provided on the second slider can be applied to the second slider 32 by using the air pressure supplied to the cylinder. Note that the pressing force applied to the first slider 31 and the second slider 32 by the auxiliary pressurizing devices 15 can be appropriately set.

[0085] The upper die 16 and the lower die 17 are configured to be able to mold the material disposed therebetween by applying pressure in one direction. For example, the upper die 16 and the lower die 17 are configured to be used as a step in a deep drawing process for molding a cylindrical can body.

[0086] The upper mold 16 is fixed to the second slide block 32. The lower mold 17 is arranged to face the upper mold 16. For example, a plurality of lower molds 17 are provided on the conveying device 18.

[0087] The conveying device 18 is configured to move the plurality of lower molds 17 to positions opposite to the upper mold 16 in sequence. Figure 1 as well as Figure 2 As shown, the conveying device 18 arranges a plurality of lower molds 17 at a predetermined interval in one direction, for example, and conveys the plurality of lower molds 17 in one direction. Here, the predetermined interval refers to an interval at which each structure of the molding device 1 does not interfere with other adjacent lower molds 17 when the upper mold 16 and the lower mold 17 are pressurized.

[0088] The control device 19 is configured to be able to control the operation of the pressurizing device 14, the auxiliary pressurizing device 15, and the conveying device 18. Specifically, the control device 19 controls, for example, the power source of the pressurizing device 14. In addition, the control device 19 controls, for example, the supply unit of the auxiliary pressurizing device 15. In addition, the control device 19 controls, for example, the feed amount of the conveying device 18 and the feed timing of the conveying device 18 corresponding to the operation of the pressurizing device 14.

[0089] An example of the operation of such a molding device 1 to mold a material through the following steps will be described.

[0090] First, the control device 19 uses the pressurizing device 14 to make the first slide 31 and the second slide 32 standby at a position where the upper mold 16 is separated from the lower mold 17. Here, the standby positions of the first slide 31 and the second slide 32 are, for example, the uppermost positions of the ranges in which they are guided to move by the pressurizing device 14 and the rail guide 13, respectively. In this state, the control device 19 uses the conveying device 18 to convey the lower mold 17 to a position opposite to the upper mold 16 fixed to the lower part of the second slide 32.

[0091] Next, the control device 19 drives the pressurizing device 14 to press the first slider 31 and the second slider 32 via the connecting portion 92. The pressed first slider 31 and the second slider 32 are guided by the rail guide 13 and move in one direction along the extending direction of the support 22.

[0092] In addition, here, the first slider 31 and the second slider 32 reciprocate in different phases. Specifically, when the pressurizing device 14 presses the first slider 31 and the second slider 32, the second slider 32 is pressed before the first slider 31 due to the phase difference of the reciprocating motion of the pressurizing device 14. As a result, the second slider 32 moves and presses the upper mold 16 to the lower mold 17 in a state where the upper surface of the second slider 32 is separated from the top plate portion 41 of the first slider 31.

[0093] Next, by moving the first slider 31 downward, the top plate 41 of the first slider 31 abuts against the second slider 32. By further pressing the first slider 31 in this state, the second slider is pressed not only by the pressurizing device 14 but also by the top plate 41 of the first slider 31. Thus, the pressing force of the upper mold 16 on the lower mold 17 increases.

[0094] In this way, the molding device 1 molds the material using the upper mold 16 and the lower mold 17 by the pressing force of the second slide 32 by the pressurizing device 14 plus the pressing force of the second slide 32 by the first slide 31 .

[0095] Next, after the molding of the material disposed on the lower mold 17 is completed, the control device 19 moves the first slider 31 and the second slider 32 upward to separate the upper mold 16 from the lower mold 17. Here, the control device 19 controls the supply unit of the auxiliary pressurizing device 15 provided on the first slider 31 and the second slider 32 to supply air to the cylinder. The auxiliary pressurizing device 15 uses the air pressure supplied to the cylinder to apply an upward pressing force to the first slider 31 and the second slider 32 in the direction of gravity, respectively, to assist the upward movement of the first slider 31 and the second slider 32.

[0096] Next, the control device 19 uses the conveying device 18 to convey the other lower mold 17 disposed next to it to a position opposite to the upper mold 16. Then, the control device 19 molds the material again according to the above-mentioned sequence.

[0097] According to the molding device 1 configured in this way, the first slider 31 and the second slider 32 are guided to move in one direction by the rail guide 13. Here, in the rail guide 13, since the guide 62 is guided to move by rotating relative to the guide rail 61, the friction resistance generated when the first slider 31 and the second slider 32 move can be reduced. Therefore, the molding device 1 can reduce the loss generated when the first slider 31 and the second slider 32 move, and thus can increase the moving speed of the first slider 31 and the second slider 32. As a result, the molding device 1 can improve productivity.

[0098] In addition, in the molding device 1, since the support is provided by different side surfaces of each support column 22, the interval between each support position of each support column 22 for the first slider 31 and the second slider 32 can be minimized. Thus, the molding device 1 can reduce the displacement of each structure caused by the load generated during molding, and can improve durability. In addition, in the molding device 1, since the guide rail 61 and the guide member 62 can be easily disassembled and assembled, the maintainability can be improved.

[0099] In addition, in the molding device 1, each support 22 is formed in a shape in which the first side surface 22a and the second side surface 22b are orthogonal to each other, and two adjacent supports 22 are arranged so that the first side surfaces 22a and the second side surfaces 22b are opposite to each other. Thus, since each structure of the molding device 1 is arranged orthogonally to the moving direction of the slider 12, the rigidity with respect to the load generated during molding can be improved. In addition, since the first side surface 22a and the second side surface 22b of the support 22 can be used as a reference, the positioning of each structure of the molding device 1 becomes easy, and the workability and maintenance of the installation can be improved.

[0100] In addition, the molding device 1 is configured such that the interval between the first side surfaces 22a facing each other of the pillars 22 is larger than the interval between the second side surfaces 22b facing each other. That is, the interval between the second slider 32 supported by the pillars 22 is smaller than the interval between the first slider 31 supported by the pillars 22. Thus, the rigidity of the second slider 32, which is subjected to a larger load than the first slider 31 during molding, can be improved.

[0101] In addition, in the molding device 1, a plurality of first guide members 62a and a plurality of second guide members 62b are provided for each first guide rail 61a or a second guide rail 61b. Thus, since the load generated during molding is borne by the plurality of guide members 62 on each guide rail 61, displacement generated on each guide member 62 and the first connecting member 43 and the second connecting member 52 connected to each guide member 62 can be reduced.

[0102] As described above, according to the molding device 1 according to one embodiment of the present invention, productivity, durability, and maintainability can be improved.

[0103] In addition, the present invention is not limited to the above-mentioned embodiment. For example, with respect to the support 22, the shape of the cross section in the horizontal direction can be appropriately set as long as the guide rail 61 of the guide rail guide 13 can be set. For example, the support 22 can also form the cross section in the horizontal direction into a polygonal shape other than a rectangle. In addition, the support 22 can also form the cross section in the horizontal direction into a circular shape. In the case where the cross section in the horizontal direction is formed into a circular shape, in the support 22, the first side surface 22a and the second side surface 22b are the same surface. At this time, in the side surface of the support 22, a part constitutes the first side surface 22a, and the other part that is offset by a specified angle phase in the circumferential direction constitutes the second side surface 22b. However, from the viewpoint of improving the rigidity of the slider 12 and the ease of positioning and setting the slider 12 and the guide rail guide 13, the support 22 is preferably formed into a rectangular cross section in the horizontal direction.

[0104] In addition, in this embodiment, an example in which the guide rail 61 is provided on the support column 22 and the guide member 62 is provided on the slider 12 is described, but the present invention is not limited thereto. A structure in which the guide member 62 is provided on the support column 22 and the guide rail 61 is provided on the slider 12 may also be provided. However, in consideration of the ease of maintenance work, it is preferable to provide the guide rail 61 on the support column 22 and the guide member 62 on the slider 12 as in the above embodiment.

[0105] In addition, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made in the implementation stage without departing from the scope of the main purpose. In addition, each embodiment can also be appropriately combined and implemented within a possible range, in which case a combined effect can be obtained. In addition, the above-mentioned embodiments include inventions at various levels, and various inventions can be extracted by appropriately combining the disclosed multiple constituent elements.
