Description

[Technical Field]

[0001] The present invention relates to a press working system that presses a sheet material to form a worked product and then transports the worked product downstream, and to a press working device used in the press working system. [Background technology]

[0002] For example, a known press working system includes a first press apparatus that performs a first press working on a workpiece, a second press apparatus that performs a second press working on the workpiece that has undergone the first press working, and a conveyance device disposed between the first press apparatus and the second press apparatus (see, for example, Patent Document 1). The conveyance device includes a conveyance belt that extends from the first press apparatus to the second press apparatus, and an upper running portion of the conveyance belt moves downstream from the first press apparatus toward the second press apparatus. In addition, a work removal hand that removes a workpiece that has undergone the first press working is provided on the discharge side of the first press apparatus, and a work insertion hand that inserts a workpiece to be subjected to the second press working is provided on the insertion side of the second press apparatus.

[0003] In such a press working system, a workpiece to be worked is subjected to a first press working by a first press device, the worked workpiece is removed from the first press device by a work removal hand and placed on a conveyor belt of a conveyor device, the placed workpiece is transported downstream by the movement of the conveyor belt and loaded into a second press device by a work loading hand, the inserted workpiece is subjected to a second press working by the second press device, and the workpiece thus subjected to the first press working is transported by the conveyor device and subjected to the second press working.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-105093 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in such a press working system, in order to transport the workpiece that has been first pressed by the first press device downstream using a transport device, it is necessary to provide a workpiece removal hand on the discharge side of the first press device and use this workpiece removal hand to grasp the workpiece and transport it to the transport device. Therefore, since a workpiece removal hand is required in addition to the transport device that transports the workpiece, the configuration of the entire press working system becomes large and complex, and further, the control thereof becomes complicated.

[0006] An object of the present invention is to provide a press working system that can simplify and downsize the overall system configuration in relation to the press working device and the transport device.

[0007] Another object of the present invention is to provide a press working apparatus that allows easy maintenance and the like in relation to the downstream working area. [Means for solving the problem]

[0008] The press working system of the present invention is a press working system including a press working device that applies press working to a sheet-like member, and a conveying device that conveys a processed product processed by the press working device downstream, the press processing device includes a bolster attached to a base member of a processing device body, and a slide that reciprocates in a direction approaching and moving away from the bolster, the bolster is provided with a plurality of fixed dies corresponding to a plurality of processing zones for processing a sheet-like material, the slide is provided with a plurality of movable dies corresponding to the plurality of fixed dies on the bolster side, and while the sheet-like material is transported through the plurality of processing zones, press processing is performed by the plurality of fixed dies on the bolster side and the plurality of movable dies on the slide side to form a processed product, The conveying device further includes a pair of rollers spaced apart in the conveying direction, a conveying belt wound between the pair of rollers, and a driving means for driving one of the pair of rollers, Corresponding to the final processing area where final press processing is performed on the sheet-like material, a fixed mold for final processing is provided on the bolster side, and a movable mold for final processing is provided on the slide side, and at least the fixed mold for final processing has an insertion recess extending from the outside of the press processing device beyond the final processing area, the upstream portion of the conveying device is inserted into the insertion recess of the fixed mold for final processing, and the upstream portion of the upper running portion of the conveying belt of the conveying device extends to at least the final processing area.

[0009] In such a press working system, a lifter mechanism for lifting the sheet-like material upward is provided on the bolster side in relation to the multiple working zones, and when the sheet-like material is to be transported downstream, the lifter mechanism positions the sheet-like material in an elevated position and moves it downstream above the multiple fixed dies. This allows the sheet-like material to be moved downstream without being affected by the structure of the multiple fixed dies. Furthermore, when working on the sheet-like material, the lifter mechanism is pressed down to position the sheet-like material in a lowered position and the sheet-like material is placed and supported on the upper surfaces of the multiple fixed dies. This allows the sheet-like material to be worked on.

[0010] When carrying out this processing, it is preferable to position the upstream side of the upper running portion of the conveying belt at the same level as or slightly lower than the top surface of the fixed mold for final processing on the bolster side.By configuring it in this way, the processed product processed in the final processing area can be placed on the upper running portion of the conveying belt in its original state and transported.

[0011] Furthermore, the conveyor belt of the conveyor device can be constructed from a pair of belt members, and a fixed final processing mold can be disposed between the pair of belt members. By configuring in this way, the space between the pair of belt members can be utilized to perform final press processing using the fixed final processing mold and the movable final processing mold. Furthermore, since a plurality of abutment pieces are provided on the surfaces of the pair of belt members, the abutment of these abutment pieces allows the processed product to be conveyed downstream in a state of being aligned in the desired position.

[0012] In such a press working system, the sheet-like material moves in a sheet state while being conveyed through multiple working zones, and is subjected to final working in the final working zone to separate it into a pair of worked products. By processing in this manner, the sheet-like material can be easily conveyed to the final working zone. Furthermore, one of the pair of worked products separated by final working is placed on one belt member of the conveyor belt and conveyed downstream, and the other of the pair is placed on the other belt member of the conveyor belt and conveyed downstream, so that each worked product can be conveyed downstream stably and reliably.

[0013] Furthermore, in such a press processing device, it is preferable to provide an idle area upstream of the downstream processing area including the final processing area, and to attach a fixed idle unit to the bolster side and a movable idle unit to the slide side corresponding to this idle area.By configuring in this manner, it is possible to move the multiple movable dies and movable idle units on the slide side back and forth relative to the multiple fixed dies and fixed idle units on the bolster side.

[0014] Furthermore, it is preferable to attach a downstream-side fixed mold mounting member to the bolster side corresponding to the downstream processing area, attach a downstream-side fixed mold including a final-processing fixed mold to this downstream-side fixed mold mounting member, and attach a downstream-side movable mold mounting member to the slide side corresponding to the downstream processing area, and attach a downstream-side movable mold including a final-processing movable mold to this downstream-side movable mold mounting member. With this configuration, the downstream-side fixed mold and the downstream-side movable mold are unitized. Furthermore, since the downstream-side fixed mold mounting member is supported so as to be movably between the downstream processing area and the idle area, this downstream-side fixed mold mounting member (or a state in which the downstream-side movable mold mounting member is placed on this downstream-side fixed mold mounting member) can be moved to the idle area, and by moving it in this manner, the downstream processing area can be opened up to create a large space.

[0015] It is also preferable to provide a slide support mechanism on the surface of the bolster corresponding to the idle zone and the downstream processing zone, attach a fixed idle unit to the slide support mechanism at a position corresponding to the idle zone so that it can be slidably removed, and attach a downstream fixed mold mounting member to the slide mechanism at a position corresponding to the downstream processing zone so that it can be slidably moved toward the idle zone. With this configuration, the fixed idle unit can be easily removed, and by removing it, the downstream fixed mold mounting member can be easily slidably moved from the downstream processing zone to the idle zone.

[0016] It is also preferable to provide a pair of engaging protrusions (or engaging recesses) on the inside of the abutment block provided at the downstream end of the bolster, and to provide a pair of engaging recesses (or engaging protrusions) on the downstream fixed mold mounting member.By configuring in this manner, when the downstream fixed mold mounting member is slid from the idle area to the downstream processing area, the pair of engaging recesses (or engaging protrusions) on the downstream fixed mold mounting member engage with the pair of engaging protrusions (or engaging recesses) on the abutment block, thereby making it possible to accurately position the downstream fixed mold member in the downstream processing area.

[0017] Furthermore, the press working device of the present invention includes a bolster attached to a base member of a processing device body, and a slide that reciprocates in a direction approaching and moving away from the bolster, wherein the bolster is provided with a plurality of fixed dies corresponding to a plurality of processing zones for processing a sheet-like material, and the slide is provided with a plurality of movable dies corresponding to the plurality of fixed dies on the bolster side, and while the sheet-like material is transported through the plurality of processing zones, press working is performed on the sheet-like material by the plurality of fixed dies on the bolster side and the plurality of movable dies on the slide side, the plurality of processing zones include an upstream processing zone located upstream in a conveying direction and a downstream processing zone located downstream of the upstream processing zone, and an idle zone is provided between the upstream processing zone and the downstream processing zone; a fixed idle unit is removably attached to the bolster in correspondence with the idle area, a downstream fixed mold mounting member is slidably attached to the bolster in correspondence with the downstream processing area, and a downstream fixed mold corresponding to the downstream processing area is mounted to the downstream fixed mold mounting member, Furthermore, a movable idle unit is removably attached to the slide side corresponding to the idle area, a downstream movable mold mounting member is attached to the downstream processing area, and a downstream fixed movable mold corresponding to the downstream processing area is attached to the downstream movable mold mounting member. [Effects of the Invention]

[0018] According to the press working system of the present invention, a final working stationary die is provided on the bolster side corresponding to the final working zone of the press working device, a final working movable die is provided on the slide side, and the upstream portion of the conveying device is inserted into the insertion recess provided in the bolster-side final working stationary die, thereby shortening the conveying length of the entire press working system combining the press working device and the conveying device and achieving compactness. Furthermore, since the upstream portion of the upper running portion of the conveying device's conveyor belt extends at least to the final working zone, the workpieces processed in the final working zone can be placed directly on the upper running portion of the conveying belt and transported downstream, thereby eliminating the need for a conventional take-out hand and achieving simplification and compactness of the entire press working system. Furthermore, since the workpieces processed by the final working stationary die and the final working movable die are placed directly on the conveying belt and transported, they can be transported downstream in an aligned state.

[0019] Furthermore, according to the press working apparatus of the present invention, the multiple working zones include an upstream working zone located upstream in the conveying direction and a downstream working zone located downstream of the upstream working zone, an idle zone is provided between the upstream working zone and the downstream working zone, a fixed idle unit is removably attached to the bolster corresponding to the idle zone, a downstream fixed mold mounting member is slidably attached to the bolster corresponding to the downstream working zone, and a downstream fixed mold corresponding to the downstream working zone is mounted to the downstream fixed mold mounting member, so that the idle zone can be opened by removing the fixed idle unit (or in addition, the movable idle unit).The downstream fixed mold mounting member (or the downstream movable mold mounting member with the downstream fixed mold mounting member mounted thereon) can then be moved toward the opened idle zone, and by moving it in this manner, the downstream working zone can be opened.

[0021] Hereinafter, an embodiment of a press working system according to the present invention will be described with reference to the accompanying drawings. Referring to Figures 1 to 3, the illustrated press working system 2 includes a press working device 4 that applies press working to a sheet-like member S, and a conveying device 6 that conveys a work H pressed by the press working device 4 downstream.

[0022] First, the press working device 4 will be described. The illustrated press working device 4 includes a processing device main body 7 including a base member 8 and the like, and the base member 8 is installed on a factory floor or the like. A bolster 10 is attached to the base member 8, and a plurality of fixed dies 12 (the fixed dies are not specifically shown) are attached to the bolster 10 (the base member 8 is omitted from the illustration in FIG. 3). A slide 14 is disposed above and facing the bolster 10, and a plurality of movable dies 16 (the movable dies are not specifically shown) are attached to the slide 14 in correspondence with each of the plurality of fixed dies 12 on the bolster 10 side. The slide 14 is supported by the processing device main body 7 so as to be reciprocatable in a direction approaching and moving away from the bolster 10, and the reciprocating movement of the slide 14 causes the plurality of movable dies 16 attached thereto to reciprocate in a direction approaching and moving away from the plurality of fixed dies 12.

[0023] Between the multiple fixed dies 12 on the bolster 10 side and the multiple movable dies 16 on the slide 14 side, multiple processing zones K (in this embodiment, first to fourteenth processing zones K1 to K14) are provided for press-processing the sheet-like material S, with an upstream processing zone being provided on the upstream side as viewed in the feed direction indicated by arrow 18 of the sheet-like material S, and a downstream processing zone being provided on the downstream side as viewed in this feed direction. In this embodiment, the first to eleventh processing zones K (K1 to K11) constitute the upstream processing zones, the twelfth to fourteenth processing zones (K12 to K14) constitute the downstream processing zones, and the last processing zone K14 is the final processing zone where final press processing is performed.

[0024] In this embodiment, an idle A is provided between the upstream processing zone K (the first to eleventh processing zones K1 to K11) and the downstream processing zone K (the twelfth to fourteenth processing zones K12 to K14), and in this form, three idle zones A, namely the first to third idle zones A1 to A3, are provided so that the sheet-like material S is idled three times.

[0025] In this press working device 4, an upstream fixed mold mounting member 20 is attached to the bolster 10 side corresponding to the upstream working zone K (K1 to K11), and an upstream movable mold mounting member 22 is attached to the slide 14 side. Upstream fixed molds 12a (first to eleventh fixed molds) are attached to this upstream fixed mold mounting member 20 corresponding to each working zone (first to eleventh working zones K1 to K11) of the upstream working zone K, and upstream movable molds 16a (first to eleventh movable molds) are attached to the upstream movable mold mounting member 22 corresponding to each working zone (first to eleventh working zones K1 to K11) of the upstream working zone K.

[0026] Also, a downstream-side fixed mold mounting member 24 is attached to the bolster 10 side corresponding to the downstream-side machining zones K (twelfth to fourteenth machining zones K12 to K14), and a downstream-side movable mold mounting member 26 is attached to the slide 14 side. This downstream-side fixed mold mounting member 24 has downstream-side fixed molds 12b (twelfth to fourteenth fixed molds) attached to it corresponding to each machining zone K (twelfth to fourteenth machining zones K12 to K14) of the downstream-side machining zone K, and further, the downstream-side movable mold mounting member 26 has downstream-side movable molds 16b (twelfth to fourteenth movable molds) attached to it corresponding to each machining zone K (twelfth to fourteenth machining zones K12 to K14) of the downstream-side machining zone K.

[0027] Furthermore, corresponding to idle range A (first to third idle ranges A1 to A3), a fixed idle unit 28 is attached to the bolster 10 side, and a movable idle unit 30 is attached to the slide 16 side. In this embodiment, fixed idle unit 28 includes a fixed unit mounting member 32 attached to bolster 10, and a fixed idle member 34 attached to this fixed unit mounting member 32. Also, movable idle unit 30 includes a movable unit mounting member 36 attached to slide 14, and a movable idle member 38 attached to this movable unit mounting member 36.

[0028] In this embodiment, the upstream processing zone K has 11 processing zones (1st to 11th processing zones K1 to K11), but the number of processing zones included in this upstream processing zone is set appropriately depending on the number of press processing steps to be performed on the sheet-like material S, and is less than 11 when the number of processing steps is small, and more than 11 when the number of processing steps is large. Also, the downstream processing zone K has three processing zones (12th to 14th processing zones K12 to K14), but the number of processing zones included in this downstream processing zone K is set appropriately depending on the number of processing steps to be performed on the sheet-like material S, and is less than three when the number of processing steps is small, and more than three when the number of processing steps is large.

[0029] In addition, three idle zones (first to third idle zones A1 to A3) are provided in the idle zone A, but the number of idle zones included in this idle zone A is set appropriately depending on the movement range of the downstream fixed mold mount 24 described below, and can be less than three when this movement range can be short, and can be more than three when this movement range is long.

[0030] A guide mechanism 42 is provided upstream of the upstream processing zone K (specifically, the first processing zone K1) for guiding the sheet-like material S in the feed direction indicated by the arrow 18, and this guide mechanism 42 has a support mounting member 44 attached to the upstream fixed mold mounting member 20, and a lower guide member 46 and an upper guide member 48 attached to the support mounting member 44, and the sheet-like material S to be processed is fed toward the processing zone K through between the lower guide member 46 and the upper guide member 48.

[0031] Further upstream of this guide mechanism 42 is disposed a feed device 50 that intermittently feeds the sheet material S downstream. The feed device 50 may be of a known structure, and operates when the slide 14 rises (specifically, when it rises to the top dead center position or a position nearby), to feed the sheet material S by a predetermined amount in the feed direction indicated by arrow 18.

[0032] 1 and 2, in order to feed the sheet-like material S downstream in a lifted state, a pair of lifter mechanisms 52, 54 are provided in association with a plurality of processing zones K (first to fourteenth processing zones K1 to K14) and an idle zone A (first to third idle zones A1 to A3). The pair of lifter mechanisms 52, 54 have substantially the same configuration, with one lifter mechanism 52 being disposed on the right side as viewed in the feeding direction indicated by arrow 18 (the near side of the paper in FIGS. 1 and 2, the right side in FIG. 3) and supporting the right side of the sheet-like material S being conveyed, and the other lifter mechanism 54 being disposed on the left side as viewed in the feeding direction indicated by arrow 18 (the far side of the paper in FIGS. 1 and 2, the left side in FIG. 3) and supporting the left side of the sheet-like material S.

[0033] In this embodiment, the pair of lifter mechanisms 52, 54 includes a first lifter pin 56 that guides, supports, and lifts the sheet-like material S, a second lifter pin 58 that supports and lifts the sheet-like material S on its upper surface, and a lifter block 60 that supports and lifts a certain range of the sheet-like material S. The first lifter pin 56, the second lifter pin 58, and the lifter block 60 are movable between an elevated state in which the sheet-like material S is elevated to an elevated position (the position shown in FIGS. 1 and 2), and a elevated state in which the sheet-like material S is moved downward to a lowered position (the position shown in FIG. 7) in which it is placed on the surfaces of the plurality of fixed molds 12 (first to fourteenth fixed molds) and the fixed idle member 34.

[0034] The first lifter pin 56, the second lifter pin 58 and the lifter block 60 are provided with bias springs 62, 64, 66 (e.g., composed of coil springs), which elastically bias the first lifter pin 56, the second lifter pin 58 and the lifter block 60 upward, lifting the sheet-like material S and holding it in a raised position.

[0035] Furthermore, when the slide 14 descends toward the bottom dead center position, the multiple movable molds 16 (1st to 14th movable molds) and a portion of the movable idle member 38 act on the first lifter pin 56, the second lifter pin 58 and the lifter block 60, pushing them down against the biasing action of the bias springs 62, 64, 66, thereby pushing down the sheet-like material S and holding it in the lowered position, and press processing is performed on the sheet-like material S while it is in this lowered position.

[0036] Next, the conveying device 6 will be described. The illustrated conveying device 6 includes a conveying frame 74 extending in the conveying direction indicated by arrow 72. This conveying frame 74 includes a pair of support frames 76, 78 spaced apart in the width direction perpendicular to the conveying direction (the support frames 76, 78 are omitted from FIG. 3). Rollers 80, 82 are rotatably supported at both ends of the pair of support frames 76, 78. In this configuration, one roller 80 is mounted to one end (the upstream end as viewed in the conveying direction) of the conveying frame 74 so that its position can be adjusted toward and away from the other roller 82. The other roller 82 is mounted to the other end (the downstream end as viewed in the conveying direction) of the conveying frame 74. An electric motor 84 (constituting a driving means) is drivingly connected to the other roller 82 via a driving force transmission mechanism (not shown), so that roller 82 functions as a driving roller and roller 80 functions as a driven roller.

[0037] An endless conveying belt 86 is wound around a pair of rollers 80, 82. In this embodiment, the conveying belt 86 is composed of a pair of belt members 88, 90, one of which, the belt member 88, is arranged inside one of the support frames 76 (the front side in Figures 1 and 2, the right support frame in Figure 3), and the other belt member 90 is arranged inside the other support frame 78 (the back side in Figures 1 and 2, the left support frame in Figure 3), with an intermediate space 92 existing between the pair of belt members 88, 90.

[0038] A plurality of abutment pieces 94 are provided on the surfaces of the pair of belt members 88, 90 at intervals in the longitudinal direction (in other words, the conveying direction indicated by arrow 72), and these abutment pieces 94 abut against the workpiece H and convey it downstream, as described below.

[0039] As configured in this manner, when the electric motor 84 is operated, its rotational force is transmitted to the conveying belt 86 (a pair of belt members 88, 90) via a drive force transmission mechanism (not shown) and the roller 82, and the upper running portion of the conveying belt 86 (a pair of belt members 88, 90) is moved in the conveying direction indicated by the arrow 72.

[0040] In this embodiment, the conveying device 6 is attached to the downstream end of the base member 8 by a support structure 96. The support structure 96 includes a pair of support members 98, 100, and one support member 98 has its upper end attached to one support frame 76 of the conveying frame 74 and its lower end attached to the base member 8. The other support member 100 has its upper end attached to the other support frame 78 of the conveying frame 74 and its lower end attached to the base member 8.

[0041] In this embodiment, the upstream longitudinal portion of the conveying frame 74 is supported on the base member 8 via a support structure 96, but in addition, the downstream portion of the conveying frame 74 may also be supported on the floor surface or the like via a downstream support structure (not shown).

[0042] A conveying / discharging mechanism 102 for discharging the workpiece H downstream is provided at the downstream end of the conveying device 6. The conveying / discharging mechanism 102 includes an upstream roller 104 that rotates integrally with the drive roller 82, and a downstream roller 108 that is rotated from the upstream roller 104 via a belt 106 (see FIG. 3), and the upstream roller 104 and the downstream roller 108 convey the workpiece H downstream.

[0043] Downstream of this conveying device 6, although not shown, there are installed, for example, a conveying device that conveys the processed product H further downstream, a cleaning device that cleans the processed product H, a drying device that dries the processed product cleaned in the cleaning device, etc., and these various devices can be arranged continuously downstream of the conveying device 6, but the processed product H conveyed by the conveying device 6 can also be conveyed to the various devices using a take-out robot or take-out hand (not shown), etc. In such a case, by conveying the processed product H conveyed by the conveying device 6 in the desired aligned state, it can be reliably taken out by the take-out robot or take-out hand.

[0044] In this embodiment, one end (upstream end) of the transport device 6 is configured to be inserted into the downstream fixed die 12b of the press working device 4. More specifically, the downstream fixed die 12b is provided with an insertion recess 112, which extends from the outside of the downstream fixed die 12b beyond the 14th working zone K14 (final working zone) to the vicinity of the 13th working zone K13. The upstream end of the transport frame 74 of the transport device 6 is inserted up to the vicinity of the 13th working zone K13.

[0045] In this embodiment, as shown in Figures 13, 15 and 17, the rectangular recesses 112a and 112b on both sides of the insertion recess 112 extend to the vicinity of the 13th processing zone K13, one belt member 88 of the conveying belt 86 extends within one rectangular recess 112a to the vicinity of the 13th processing zone K13, and the other belt member 90 extends within the other rectangular recess 112b to the vicinity of the 13th processing zone K13.

[0046] 2, the upper running portion of the conveyor belt 86 (pair of belt members 88, 90) of the conveyor device 6 extends slightly beyond the fourteenth processing zone K14 (final processing zone), and this upper running portion is configured to extend at least to the final processing zone. The upstream end of the upper running portion of the conveyor belt 86 (pair of belt members 88, 90) is preferably positioned at the same level as or slightly lower than the upper surface of the fourteenth fixed mold (final processing fixed mold). With this configuration, as will be described later, the processed product H, which has been finally processed in the fourteenth processing zone K14 (final processing zone), is placed on the upper running portion of the conveyor belt 86 (pair of belt members 88, 90) in a processed state by its own weight and transported downstream.

[0047] This press processing device 4 is further configured as follows in relation to the fixed idle unit 28 and movable idle unit 30 in the idle area A (first to third idle areas A1 to A3) and the downstream fixed mold 12b (downstream fixed mold mounting member 24) and downstream movable mold 16b (downstream movable mold mounting member 26) in the downstream processing area K (twelfth to fourteenth processing areas K12 to K14).

[0048] 1 and 13 to 16, a slide support mechanism 122 is provided on the upper surface of the bolster 10 corresponding to the idle area A and the downstream machining area K, and this slide support mechanism 122 is composed of a plurality of support units 124 attached to the upper surface of the bolster 10. The plurality of support units 124 have substantially the same configuration and include a support block 126 fixed to the upper surface of the bolster 10 and a spherical member 128 rotatably held by this support block 126 (only the spherical member is shown in FIGS. 14 and 16). The fixed idle unit 28 (fixed unit mounting member 32) and the downstream-side fixed mold 12b (downstream-side fixed mold mounting member 24) are attached to the bolster 10 via the plurality of support units 124 (specifically, the spherical member 128).

[0049] 1, the fixed unit mounting member 32 is supported by a plurality of support units 124 arranged corresponding to the idle region A (first to third idle regions A1 to A3), and is attached to the bolster 10 by threading fixing screws (not shown) into the bolster 10 through the fixed unit mounting member 32. Also, the downstream-side fixed mold mounting member 24 is supported by a plurality of support units 124 arranged corresponding to the downstream-side machining region K (twelfth to fourteenth machining regions K12 to K14), and is attached to the bolster 10 by threading fixing screws (not shown) into the bolster 10 through the downstream-side fixed mold 12b (twelfth to fourteenth fixed molds) and the downstream-side fixed mold mounting member 24.

[0050] With this configuration, the fixed unit mounting member 32 and the fixed idle member 34 can be removed from the bolster 10 by removing fixing screws (not shown) or the like, and this removal can open the idle area A (first to third idle areas A1 to A3) in the bolster 10. Furthermore, by removing fixing screws (not shown) or the like, the fixed state of the downstream side fixed mold mounting member 24 and the downstream side fixed mold 12b (twelfth to fourteenth fixed molds) can be released, and in this released state, the downstream side fixed mold mounting member 24 (and the downstream side fixed mold 12b) can be slid toward the idle area A side to open the downstream side processing area K (twelfth to fourteenth processing areas K12 to K14), and a space can be created around the upstream part of the conveying device.

[0051] In this embodiment, an abutment block 132 is provided at the downstream end of the bolster 10, and when the downstream fixed mold mounting member 24 is slid downstream toward the conveying device 6, the downstream fixed mold mounting member 24 abuts against the abutment block 132, preventing it from sliding beyond the abutment block 132.

[0052] In addition, guide blocks 134a, 134b, and 136 are arranged on both sides in the width direction (vertical direction in FIG. 3) of the downstream machining zone K. The guide blocks 134a and 134b are arranged continuously on one side in the width direction of the downstream machining zone K, extending from the idle zone A to the downstream machining zone K, and the guide block 136 is arranged on the other side in the width direction of the downstream machining zone K, extending from the idle zone A to the downstream machining zone K.

[0053] Because of this configuration, when the downstream fixed mold mounting member 24 slides between the downstream processing zone K and the idle zone A, one side in the width direction is guided by the guide blocks 134a and 134b, and the other side in the width direction is guided by the guide block 136. Furthermore, the guide block 134a corresponding to the idle zone A can be removed separately from the guide block 134b corresponding to the downstream processing zone K. By removing this guide block 134a, the front side of the idle zone A is opened, and the fixed idle unit 28 can be slid forward through this opened portion and removed.

[0054] In this embodiment, a pair of engaging protrusions 138 are further provided on the inside of the abutment block 132, and a pair of engaging recesses 140 are provided on the downstream stationary mold mounting member 24 corresponding to the pair of engaging protrusions 138. In this embodiment, the engaging protrusions 138 are formed, for example, by rod-shaped pins, and the engaging recesses 140 are formed, for example, by concave notches. When the downstream stationary mold mounting member 24 is slid from the idle zone A to the downstream processing zone K, the pair of engaging recesses 140 on the downstream stationary mold mounting member 24 engage with the pair of engaging protrusions 138 on the abutment block 132, thereby enabling the downstream stationary mold mounting member 24 to be accurately positioned at a position corresponding to the downstream processing zone K.

[0055] In this embodiment, an engaging protrusion 138 is provided on the abutment block 132 side and an engaging recess 140 is provided on the downstream side fixed mold mounting member 24 side, but the opposite may be true, where an engaging recess is provided on the abutment block 132 side and an engaging protrusion is provided on the downstream side fixed mold mounting member 24 side.

[0056] Next, we will explain press working by the above-mentioned press working system 2. When performing press working, the feed device 50 feeds the sheet-like material S a predetermined amount at a time in the feed direction indicated by the arrow 18, and the processed portion of the sheet-like material S is fed to the next processing zone. That is, an unprocessed portion is fed to the first processing zone K1, and the portions processed in the first to eleventh processing zones K1 to K11 are fed to the next second to eleventh processing zones K2 to K11 and the first idle zone A1. Furthermore, the parts located in the first to third idle zones A1 are fed to the next second to third idle zones A2 to A3 and the 12th processing zone K12, and further, the parts processed in the 12th to 13th processing zones K12 to K13 are fed to the next 13th to 14th processing zones K13 to K14, and the part processed in the 14th processing zone K14 (final processing zone) is separated into two processed products H as described below, placed on the conveying belt 86 (a pair of belt members 88, 90) of the conveying device 6, and conveyed downstream.

[0057] When the slide 14 is at or near the top dead center, the press working device 4, the conveying device 6, etc. are in the states shown in Figures 4 and 5. That is, the sheet material S is lifted upward by the pair of lifter mechanisms 52, 54, and in this state, the feed device 50 feeds the sheet material S downstream by a predetermined amount as described above. For example, the portion of the sheet material S that has been processed in the thirteenth processing zone K13 is fed to the fourteenth processing zone K14 downstream in the feed direction indicated by arrow 18. Furthermore, the conveying device 6 is operated intermittently, and the workpiece H that has been processed in the fourteenth processing zone K14 is placed on the conveying belt 86 (a pair of belt members 88, 90) and conveyed a predetermined distance in the conveying direction as the conveying belt 86 (a pair of belt members 88, 90) moves in the conveying direction indicated by arrow 72.

[0058] Then, when the slide 14 descends to the bottom dead center, as shown in Figures 6 to 9, the multiple movable molds 16 (1st to 14th movable molds) and part of the movable idle member 38 act on the first lifter pin 56, the second lifter pin 58 and the lifter block 60 (see Figure 2) and push them downward, causing the sheet-like material S to descend and be positioned in a lowered position, where it is placed and supported on the surfaces of the multiple fixed molds 12 (1st to 14th fixed molds) and the fixed idle member 34.

[0059] At this time, a plurality of fixed dies 12 on the bolster 10 side (the upstream fixed die 12a and the downstream fixed die 12b, the first to fourteenth fixed dies) and a plurality of movable dies 16 on the slide 14 side (the upstream movable die 16a and the downstream movable die 16b, the first to fourteenth movable dies) act on the sheet-like material S to perform the required press processing, and in this way the sheet-like material S is press-processed in each processing zone (the first to fourteenth processing zones K1 to K14).

[0060] In particular, in the 14th processing zone K14 (final processing zone), the workpiece H is subjected to separation press processing as follows: Up to the final processing zone (14th processing zone K14), the sheet-like material S is fed in a sheet state (see Figures 1 and 2), but is separated by final press processing in this final processing zone to form two workpieces H.

[0061] As shown in Fig. 9, a final working stationary die 12S (fourteenth fixed die) is attached to the bolster 10 side corresponding to the final working area (fourteenth working area K14), and a final working movable die 16S is attached to the slide 14 side, and punching press processing is performed by the final working stationary die 12S and the final working movable die 16S. In this configuration, a punch hole 146 corresponding to the approximately H-shaped punching shape is formed in the final working stationary die 12S, and a punch 148 corresponding to the shape of the punch hole 146 on the final working stationary die 12S side is formed in the final working movable die 16S, and the punch 148 of the final working movable die 16S and the punch hole 146 of the final working stationary die 12S punch out the center of the tip side of the sheet-like material S into an H shape as shown in Fig. 9, and by performing punching press processing in this manner, two processed products K are separated and formed on both sides in the conveyance direction from the sheet-like material S. As shown in FIG. 7, the portion 150 punched out by the punch 148 is discharged from the punch hole 146 through a discharge hole 152.

[0062] 6, 8, and 9, the workpiece H separated in the final processing zone (fourteenth processing zone K14) is split into two parts by its own weight and placed on the conveyor belt 86 (a pair of belt members 88, 90) of the conveyor device 6. In this embodiment, the punch hole 146 of the fixed final processing die 12S and the punch 148 of the movable final processing die 16S are positioned between the pair of belt members 88, 90, and therefore, when the central portion of the leading end side of the sheet-like material S is punched by press processing as described above, one of the separated workpieces H is placed and supported on the upper running portion of one of the belt members 88 by its own weight, and the other separated workpiece H is placed and supported on the upper running portion of the other belt member 90 by its own weight.

[0063] When the slide 14 rises toward the top dead center, the first lifter pins 56, the second lifter pins 58, and the lifter block 60 (see FIG. 2) rise due to the elastic restoring forces of the bias springs 62, 64, and 66, thereby lifting the sheet-like material S upward. When the slide 14 rises to the vicinity of the top dead center, as shown in FIGS. 10 and 11, the multiple movable molds 16 (first to fourteenth movable molds) and the movable idle member 38 move away from the first lifter pins 56, the second lifter pins 58, and the lifter block 60 (see FIG. 2), and the first lifter pins 56, the second lifter pins 58, and the lifter block 60 protrude upward due to the action of the bias springs 62, 64, and 66, and the sheet-like material S is held in the raised position.

[0064] When the slide 14 moves to near the top dead center in this manner, the conveying device 6 operates intermittently, and the upper running portions of the pair of belt members 88, 90 move in the conveying direction indicated by arrow 72. As a result, the plurality of contact pieces 94 move together with the pair of belt members 88, 90, and these contact pieces 94 come into contact with and push the placed workpieces H, and thus the two separated workpieces H are conveyed downstream while being pushed by the contact pieces 94 while placed on the belt members 88, 90. At this time, the contact pieces 94 come into contact with and push one end face of the workpieces H (the end face on the upstream side as viewed in the conveying direction indicated by arrow 72), so that the workpieces H are held in a predetermined state by the contact pieces 94, and thus each workpiece H can be conveyed while maintained in a constant state.

[0065] Thereafter, when the slide 14 rises to the top dead center, the feeding of the sheet-like material S resumes as described above, and the sheet-like material S is fed a predetermined amount in the feeding direction indicated by the arrow 18 while held in the raised position, and the above-described press processing is performed on the fed portion, and in this manner the press processing of the sheet-like material S is repeated.

[0066] Furthermore, in this press processing system 2, the downstream fixed die mounting member 24 (and the 12th to 14th fixed dies) of the press processing device 4 is configured to be able to slide between the idle area A (the 1st to 3rd idle areas A1 to A3) and the downstream processing area K (the 12th to 14th processing areas K12 to K14), and this sliding movement can be performed, for example, as follows.

[0067] 12 and 13, the slide 14 is positioned at the bottom dead center position, and the upstream movable mold 16a, movable idle unit 30, and downstream movable mold 16b are placed on the upper surfaces of the upstream fixed mold 12a (first to eleventh fixed molds), fixed idle unit 28, and downstream fixed mold 12b (twelfth to fourteenth fixed molds). In this state, the movable unit mounting member 36 and downstream movable mold mounting member 26 are removed from the slide 14, and then the slide 14 is raised to the top dead center position. In this manner, the movable idle unit 30 is placed on the upper surface of the fixed idle unit 28, and the downstream movable mold 16b is placed on the upper surface of the downstream fixed mold 12b.

[0068] 14 and 15, guide block 134A is removed to open the front side of idle area A, and fixed idle unit 28 (with movable idle unit 30 placed on its upper surface) is slid to this opened front side. Since fixed idle unit 28 (fixed unit mounting member 32) is supported by multiple support units 124 of slide support mechanism 122, fixed idle unit 28 and movable idle unit 30 can be easily removed from idle area A by sliding fixed idle unit 28 to the front side.

[0069] When removed in this manner, a relatively large space 152 is created inside the downstream fixed mold 12b and the downstream movable mold 16b (on the left side in Figures 14 and 15), making it possible to move the downstream fixed mold 12b (with the downstream movable mold 16b placed on its upper surface) toward this space 152.

[0070] Thereafter, the downstream-side fixed mold mounting member 24 (the downstream-side fixed mold 12b, downstream-side movable mold 16b, and downstream-side movable mold mounting member 26 mounted thereon) is slid in the direction indicated by arrow 154 (see FIG. 14) to move to the idle area A. During this sliding movement, the downstream-side fixed mold mounting member 24 is supported by the multiple support units 124 of the slide support mechanism 122, so that the movement can be easily performed.

[0071] By sliding in this manner, as shown in Figures 16 and 17, the downstream processing area K (12th to 14th processing areas K12 to K13) is opened, and the upstream part of the conveying device 6, i.e., the part that was inserted into the insertion recess 112 of the downstream fixed mold 12b, is exposed.By exposing it in this manner, maintenance of the conveying device 6, particularly its upstream part, becomes easier, and maintenance and inspection of this press processing system can be easily carried out.

[0072] For example, to return the upstream portion of the conveying device 6 to its original state after inspecting it, the downstream stationary mold mounting member 24 (with the downstream stationary mold 12b and downstream movable mold 16b and downstream movable mold mounting member 26 attached thereto) is positioned in the downstream processing zone K (twelfth to fourteenth processing zones K12 to K14), and then the fixed idle unit 28 (with the movable idle unit 30 placed on its upper surface) is attached to the idle zone A (first to third idle zones A1 to A3). When the downstream stationary mold mounting member 24 is positioned in the downstream processing zone K, the engaging protrusion 138 on the abutment block 132 fits into and engages with the engaging recess 140 on the downstream stationary mold mounting member 24, and thus the downstream stationary mold mounting member 24 can be positioned in a predetermined position.

[0073] Thereafter, the slide 14 is positioned at the bottom dead center position, the movable unit mounting member 36 is attached to the slide 14, and then the downstream movable mold mounting member 26 is attached to the slide 14. In this way, inspection of, for example, the upstream portion of the conveying device 6 is completed.

[0074] Although one embodiment of the press working system according to the present invention has been described above, the present invention is not limited to this embodiment, and various modifications and alterations are possible without departing from the scope of the present invention.

[0075] For example, in this press processing system, the downstream fixed mold mounting member (downstream fixed mold) is configured to be slidable toward the idle area in combination with a conveying device, but this configuration is not limited to this, and the downstream fixed mold mounting member (downstream fixed mold) can also be configured to be slidable toward the idle area in a press processing device that does not have a conveying device.
