Abstract

The present invention provides a transfer press that can use a common driving source for press-working in a mold and pitch conveyance of the processed product and can eliminate the need for a tuning mechanism.
A rack is moved horizontally by a lifting motor of a slide (molds 10 to 12) via a conversion mechanism of racks 16 and 20 and a pinion 18. A transport unit 30 (including a transport bar 40) in an initial state that is so-called intermittently driven with respect to the transport base 22 fixed to the rack 20 pitch transports the pressed product. That is, since the power source of the transport unit is lifted and lowered by the slide 13 for continuous press operation, a separate transport motor is not required. In addition, since the conveyance unit pitch conveys the processed product intermittently at a predetermined timing when it comes into contact with the conveyance bar with respect to the conveyance table, a synchronization mechanism that synchronizes with the lifting motor becomes unnecessary. Accordingly, since the transport motor and the synchronization mechanism other than the lifting / lowering motor of the slide 13 may be unnecessary, the configuration is simpler and less expensive than the conventional one.

Description

  The present invention relates to a transfer press in which a processed product to be pressed is pitch-conveyed between dies in a machine body.
  Patent Document 1 discloses a transfer press conveying apparatus that can independently operate a plurality of crossbars in the feed direction and the lift direction (see the “Problem” column in the summary and FIG. 1). This transfer press is provided with a pair of feed bars extending in the line direction on both sides of a mold row arranged in parallel in the line direction, and extends perpendicularly to the line direction at a pitch equal to the pitch between the molds between the feed bars. Cross the crossbar. And while raising and lowering a feed bar, a cross bar is reciprocated to a line direction with respect to a feed bar. A press material gripping tool attached to each cross bar is used to convey the press material from the upstream mold to the downstream mold (see paragraph “0002”).
  Further, Patent Document 2 has a simple, inexpensive, lightweight and compact configuration that makes the setup work easy, quick and accurate, eliminates the need for lubrication to the drive mechanism, and extends the demand for an improvement in the work conveyance speed. In addition, there is disclosed a transfer press work transfer device capable of responding to an improvement in production efficiency and the like. This work transport device moves the work holding means supported along the longitudinal direction of the crossbar and the work holding means supported and guided by the guide means along the longitudinal direction of the crossbar. Drive means for driving in this manner, and brake means that act in a different path from the drive means to fix and release the position of the work holding means with respect to the longitudinal direction of the crossbar (see summary).
JP 2005-66670 A JP 2011-224590 A
  In the transport device of Patent Document 1, a motor is disposed as a driving device for the crossbar (see paragraph numbers “0023” and “0024”). In addition, a motor is disposed as a crossbar driving device in the transport device of Patent Document 2 (see paragraph “0030”). That is, the above-described press machine with a feed device further includes a transport motor for moving the crossbar in addition to the lifting motor for moving the upper die or the lower die (synonymous with “slide”).
  In a press machine with a feed device, in order to synchronize the transport motor of the cross bar and the upper or lower die lifting motor, each drive needs to be a drive device such as a servo motor. In particular, in this press machine, since the amount of elevation of the upper die or the lower die is different from the amount of movement of the crossbar, it is difficult to obtain the same drive device. Therefore, the press machine described above requires a tuning mechanism such as a plurality of servo motors and a substrate that synchronizes them, so that the cost is high. In the above-described press machine, there is a type in which the slide is stopped at, for example, a press top dead center until the crossbar finishes moving.
  It is an object of the present invention to provide a transfer press that can use a common driving source for press-working with a mold and transporting pitches of the processed products, and can eliminate the need for a tuning mechanism.
  The transfer press according to the present invention is a transfer press for transferring a workpiece to be pressed to a pitch between molds in a machine body. Conveyance platform connected to the bolster of the machine main body so as to be in contact with and away from the conveyance platform, and transporting the processed product at a pitch while the mover (including the cam plate) moves along the cam mechanism. A unit, and press-working while only the transport table moves.
  In the above-described transfer press, the conversion mechanism includes a mold rack connected to the ascending / descending mold, a pinion that meshes with the mold rack and is disposed on the bolster, and meshes with the pinion and the mold rack. You may comprise with the conveyance rack arrange | positioned in the direction orthogonal to. The transfer press of the present invention may further include a spring connected to the mover of the transport unit. Further, in the transfer press of the present invention, a work finger may be mounted on the cam plate of the mover.
  Here, the work finger is configured to suck, transfer, and release the processed product in the same manner as the existing product. That is, the work finger includes a plurality of (for example, three) finger portions, and a vacuum suction device or the like is disposed in each finger portion. Further, the spring connected to the mover (including the transport bar) cushions an impact when the transport table collides with the transport bar, and holds the transport bar separated from the transport table at the initial position.
  The present invention converts the elevation of the mold (slide) to be pressed into an orthogonal direction (horizontal movement) via a conversion mechanism (mold rack, pinion, transport rack), and this conversion mechanism (transport rack) A so-called intermittent drive unit (including a mover) that is intermittently driven with respect to the transport table to be connected pitches the workpiece. That is, in the present invention, the power source (lifting motor) of the transport unit is lifted and lowered by the slide for pressing, so that another transport motor is not required.
  In the present invention, the conveyance unit pitches the processed product intermittently at a predetermined timing at which the conveyance table fixed to the conversion mechanism comes into contact with the mover (specifically, the conveyance bar) of the conveyance unit. Since it is transported, there is no need for a tuning mechanism (for example, a servo motor and a substrate) that synchronizes with the lifting motor. For this reason, according to the present invention, the above-described transport motor and tuning mechanism other than the mold lifting motor may be unnecessary, and thus the configuration becomes simpler than the conventional one.
  Therefore, according to the present invention, the drive source for performing the press working with the mold and the pitch conveyance of the processed product can be made common, and the above-described tuning mechanism can be made unnecessary. Equipment costs are reduced. That is, according to the present invention, since the pitch conveying mechanism mechanically intermittently follows the continuous operation of the press working, the workpiece conveyance is synchronized with the SPM (number of strokes) of the slide, and the productivity is improved as compared with the prior art.

Note that the bolster 28 of the machine body is disposed on the bed 24. In addition, the transfer press P is provided with a storage box 26 that stores the pressed workpiece W2.
  Here, the upper molds 10 to 12 are fixed to the slide 13. The slide 13 is connected to a lifting motor (not shown). The lower die 14 is fixed to the bolster 28 so as to face the upper die 10. On the bolster 28, a pair of lower molds (not shown) are arranged to face the upper molds 11 and 12. That is, the molds 10 and 14 are punching types, the upper mold 11 on the downstream side (right side) is a drawing type, and the upper mold 12 on the further downstream side is a bending type.
(Configuration related to conversion mechanism)
As shown in FIG. 1, the conversion mechanism includes a mold rack 16 connected to a slide 13 (including upper molds 10 to 12) that moves up and down, and a pinion 18 that meshes with the mold rack 16 and is disposed on a bolster 28. And a transport rack 20 that meshes with the pinion 18 and is disposed in a direction orthogonal to the mold rack 16. That is, the mold rack 16 is arranged so that the longitudinal direction thereof is in the vertical direction (see the arrow in FIG. 1). The transport rack 20 is arranged so that its longitudinal direction is in the left-right direction (see the arrow in FIG. 1).
  These racks 20 and 16 are set in advance so that the length in the longitudinal direction is lowered until the upper molds 10 to 12 can be pressed with the lower mold 14 and the like. Further, rack teeth 16A and 20A are formed on the side surfaces in the longitudinal direction of the racks 16 and 20, respectively. The pinion 18 is formed so that the racks 16 and 20 do not interfere (synonymous with “contact”) on the same surface.
  That is, the outer peripheral surface of the pinion 18 has two stages of large and small, and pinion teeth 18A and 18B are formed on the respective outer peripheral surfaces. The large-diameter pinion teeth 18A mesh with the rack teeth 16A of the mold rack 16, and the small-diameter pinion teeth 18B mesh with the rack teeth 20A of the transport rack 20. A cover case (not shown) is disposed in the vicinity of the pinion 18, and this cover case prevents dust and the like from adhering to the pinion 18 and the like.
(Schematic configuration of transport unit mechanism)
As shown in FIG. 1, a transport base 22 is connected to the front end (left end) of the transport rack 20. The lower part 22 </ b> A of the carrier 22 is fitted into a rail 25 on the bed 24 and slides along the rail 25. In addition, the head 22 </ b> B is formed on the transport base 22 so as to abut on a transport bar 40 of the transport unit 30 described later (synonymous with “collision”).
  That is, the transport table 22 is arranged so as to be in contact with and away from the transport bar 40. And while the conveyance stand 22 is spaced apart from the conveyance bar 40, the conveyance bar 40 is hold | maintained at an initial state (state shown in FIG. 1), and press work is performed with the metal mold | dies 10-12, 14 grade | etc.,. On the other hand, at the timing when a work finger 48 (see a two-dot chain line in FIG. 2) to be described later enters the lower mold 14 or the like, the transport table 22 comes into contact with the transport bar 40 and the transport unit 30 is intermittently operated. FIG. 1 shows a state in which the transport table 22 is separated from the transport bar 40.
  As shown in FIG. 1, one end of a spring 27 is hooked on the tip of the transport bar 40, and the other end of the spring 27 is hooked on a hook portion (not shown) of the machine body. . Therefore, the transport bar 40 is always urged toward the other end side (left side) of the spring 27 by the urging force of the spring 27. Therefore, the spring 27 cushions an impact when the transport table 22 collides with the transport bar 40, and holds the transport bar 40 where the transport table 22 is separated from the initial position (position shown in FIG. 1).
(Configuration related to the transport unit 30)
As shown in FIGS. 1 to 4, the conveyance unit 30 that performs conveyance in the press has a movable plate (indicated by a broken line in FIG. 1) 38 that moves along the cam mechanism 50 shown in FIGS. 2 and 4. Further, the workpiece W2 (refer to the two-dot chain line in FIG. 1) and the like are pitch-conveyed with a predetermined pitch width (synonymous with “feed pitch”).
  As shown in FIGS. 2 and 4, the transport unit 30 includes a flat plate base 32 placed on the bolster 28 (see FIG. 1), a flat guide plate 34 erected on the base 32, and A movable element 36 that is movably arranged in parallel with the guide plate 34 and a cam mechanism 50 that is connected to the movable element 36 and is erected on the base 32 are provided.
  As shown in FIGS. 1 and 3, the guide plate 34 is formed with linear long holes 34 </ b> A along the left-right direction. The long hole 34A is set in advance so as to correspond to the moving length for pitch-conveying the workpiece W2 (see FIG. 1) and the like. Further, as shown in FIGS. 2 and 3, the transport bar 40 of the mover 36 is inserted into the long hole 34 </ b> A. The transport bar 40 is disposed on the movable plate 38 of the mover 36.
  Further, a stopper 35 (shown in FIGS. 1 and 4) is fixed to the left end of the guide plate 34. Here, in this embodiment, since the transport unit 30 is a portable type that is placed on the bolster 28, a new space for installing the transport unit 30 is not required.
(Configuration related to the mover 36)
As shown in FIGS. 2 and 4, the movable element 36 includes the movable plate 38 described above, a plurality of guide bodies 42 fixed to the front surface side of the movable plate 38, and a plurality of movable members 38 disposed on the back side of the movable plate 38. And a cam plate 52 connected to these elevators 44. A pair of rails 33 is fixed to the guide plate 34 in a straight line in the left-right direction so as to face the guide body 42. Therefore, the movable plate 38 is configured to only slide in the left-right direction.
  On the other hand, the elevator 44 is disposed on the cam plate 52. The elevator 44 (including the cam plate 52) is configured to move up and down with respect to the movable plate 38. That is, as shown in FIGS. 2 and 4, a pair of rails 39 are fixed to the movable plate 38 on the back surface in a straight line in the vertical direction so as to face the elevator 44. That is, the elevating element 44 is fitted (connected) to the rail 39, that is, the movable plate 38 so as to be movable up and down.
  As shown in FIG. 2, the spring receivers 52 </ b> A (see FIG. 4) and 38 </ b> A are arranged so as to face the cam plate 52 and the movable plate 38 of the mover 36. A spring 46 is mounted between the spring receiver 38A and the spring receiver 52A so as to constantly urge the cam plate 52 (including the elevator 44) downward. The spring 46 may be inserted through a shaft (not shown).
(Configuration related to the cam mechanism 50)
As shown in FIGS. 2 and 4, a roller 54 is rotatably supported at the lower left corner of the back surface of the cam plate 52 constituting a part of the cam floor. As shown in FIG. 5, the roller 54 is set so as to roll a forward rotation cam portion 58 and a reversing detour portion 60 described later. Therefore, the cam plate 52 is at a height position where the roller 54 and the cam portion 58 or the detour portion 60 abut on each other due to the urging force of the spring 46.
  As shown in FIG. 2, a cam base 56 is fixed on the base 32. As shown in FIG. 5, the cam base 56 includes a cam portion 58 having two bottom dead centers 59A and 59B, and a bypass portion 60 (see FIG. 2) disposed above the cam portion 58 serving as the feed pitch. ) And a changer 62 that couples the bypass portion 60 and the cam portion 58. The changer 62 has a base end 62 </ b> A attached to the right end of the bypass portion 60 by, for example, a bolt 61 so as to be rotatable.
  Specifically, the cam portion 58 forms substantially V-shaped bottom dead centers 59A and 59B with respect to substantially straight reference surfaces (also referred to as “conveying surfaces”) 58A to 58C. The pair of bottom dead centers 59A and 59B are set in advance so as to coincide with the center points of the molds 10 to 12 shown in FIG. Therefore, the work finger 48 described later can appropriately suck or discharge (synonymous with “placement”) the above-mentioned processed products with respect to the lower mold 14 or the like.
  Further, as shown in FIG. 5, the changer 62 is arranged so that the tip 62 </ b> B abuts to the right of the bottom dead center 59 </ b> B on the conveyance surface 58 </ b> C of the cam portion 58 due to its own weight. The transport surfaces 58A to 58C divided by the first bottom dead center 59A and the second bottom dead center 59B have the same height, and these transport surfaces 58A to 58C and the bottom dead centers 59A and 59B. The difference in height is the amount of work list.
  Here, since the above-mentioned feed pitch is determined at the center of each mold 10-12, various settings can be made as appropriate by changing the settings of the conveyance amounts such as the conveyance surfaces 58A to 58C or the bottom dead centers 59A and 59B. It can correspond to a workpiece (processed product). That is, although the lift amount and the transport amount of the work finger 48 vary depending on various workpieces, in this embodiment, it is possible to correspond to various workpieces by arbitrarily changing the setting of the transport unit 30.
  Further, as shown by a two-dot chain line in FIG. 2, a work finger 48 is fixed to the upper end surface of the cam plate 52. The work finger 48 is configured to suck, transfer, and release (synonymous with “suction release”) a processed product in the same manner as an existing product. That is, the work finger 48 includes a plurality of (three in this example) finger portions 48A, and vacuum suction devices (not shown) are arranged on the finger portions 48A, respectively. In addition, since the structure regarding these vacuum suction apparatuses is the same as that of the existing structure, detailed description is abbreviate | omitted.
(Operation of this embodiment)
The transfer press P shown in FIG. 1 raises and lowers the slide 13 (the same applies to the upper molds 10 to 13) to press the material W1 or a subsequent processed product, and also performs the above-described processing by sliding the racks 16 and 20 or the like. Pitch the product. This pitch conveyance is a multi-in-press process (pitch conveyance process) in which these processed products are pressed multiple times. In the contact state between the conveyance bar 40 and the head portion 22B of the conveyance table 22. This is performed while the mover 36 is sliding.
  That is, the transfer press P starts the pitch conveyance by the conveyance unit 30 at a predetermined timing at which the conveyance table 22 comes into contact with the conveyance bar 40, separately from the slides 13 (upper molds 10 to 12) that perform continuous pressing and pressing. Is done. For this reason, the above-mentioned processed products are sequentially pitch-conveyed by a work finger 48 indicated by a two-dot chain line in FIG. And after press-processing with each metal mold | die 10-12 and 14, etc., it finally accommodates in the storage box 26 as the processed product W2.
  First, at the initial position of the transport unit 30 (including the movable element 36), the roller 54 is positioned on the transport surface 58A (origin) indicated by a broken line in FIG. When the racks 16 and 20 shown in FIG. 1 are further slid in a state in which the transfer table 22 is separated from the transfer bar 40 (as shown in FIG. 1), the material W1 (see FIG. 1) and subsequent processing are performed. Each product is pressed.
  In the initial position, the work fingers 48 (see the two-dot chain line in FIG. 2) are separated so as not to be sandwiched between the molds 10 to 12 and the like (see FIG. 1), and the cam plate 52 is a movable plate. 38, that is, the bolster 28 shown in FIG. 1 is held at a predetermined height (see the broken line in FIG. 5). In the initial position state (initial state), as shown in FIGS. 2 and 5, the cam plate 52 is located near the middle of the movable plate 38, and the upper portions of the rail 39 and the spring 46 are exposed. Yes.
  Next, the mover 36 (including the movable plate 38) of the transport unit 30 slides on the head 22 </ b> B of the transport base 22 via the transport bar 40. Therefore, as shown by the broken line in FIG. 6, when the roller 54 in the initial state moves from the origin (see the broken line in FIG. 5) to the first bottom dead center 59 </ b> A, the work finger 48 moves the processed product in each lower die 14. Adsorb each. That is, as shown in FIG. 6, since the cam plate 52 is urged downward by the spring 46, the work finger 48 can be lowered to adsorb the workpieces in the respective lower molds 14 respectively.
  Then, in these attracted states, as shown by the broken line in FIG. 7, when the roller 54 moves from the bottom dead center 59A to the conveying surface 58B, the work fingers 48 are raised and the respective processed products are also lifted from the respective lower molds 14 and the like. Are transported in the state of being transported. That is, since the cam plate 52 shown by the broken line in FIG. 7 is compressed and lifted against the urging force of the spring 46, the work finger 48 is raised.
  Further, as shown by the broken line in FIG. 8, when the roller 54 moves from the conveyance surface 58B to the bottom dead center 59B, the work finger 48 moves the processed product to the lower mold or the storage box 36 corresponding to the next molds 11 and 12. To each passage. That is, since the cam plate 52 shown by the broken line in FIG. 8 is urged downward by the spring 46, the work finger 48 is lowered, and the workpiece is placed on each of the lower molds (not shown).
  Then, as shown by the broken line in FIG. 9, when the roller 54 moves from the second bottom dead center 59B to the conveyance surface 58C, the feeding process ends. In other words, since the workpiece feeding operation has been completed, the workpiece is not attracted to the work fingers during this movement, so that the workpiece is conveyed in a so-called collar. As shown by the broken line in FIG. 9, the cam plate 52 is compressed and lifted against the urging force of the spring 46, so that the work finger 48 is conveyed in a raised state.
  Further, the roller 54 shown by the broken line in FIG. 9 abuts on the tip 62B of the changer 62 (see the two-dot chain line in FIG. 9) before and after ascending from the bottom dead center 59B to the conveying surface 58C. Therefore, the changer 62 has its distal end 62B pushed up and rotates around the proximal end 62A. When the roller 54 further travels on the conveyance surface 58 </ b> C, the roller 54 is separated from the tip 62 </ b> B of the changer 62 as indicated by a two-dot chain line in FIG. 9. Accordingly, the tip 62B rotates to contact with the conveyance surface 58C by its own weight and returns to the initial state.
  Finally, the roller 54 ascends the changer 62 (see the one-dot chain line in FIG. 10) and travels along the bypass 60 (see the broken line and the two-dot chain line in FIG. 10). 10 is further compressed and lifted against the urging force of the spring 46 (see FIG. 9), and the cam plate 52 rises to a position facing the upper portion of the movable plate 38. For this reason, the work finger 48 is also folded back in a further raised state.
  Then, the roller 54 descends from the left end of the bypass portion 60 (see the two-dot chain line in FIG. 5) and returns to the initial position (origin) (see the broken line in FIG. 5). Subsequently, by repeating the above-described series of reciprocating operations three times, the processed product from the material W1 becomes a final processed product W2 indicated by a two-dot chain line in FIG. In other words, in the present embodiment, the so-called intermittently driven transport unit 30 sequentially transports each of the above-mentioned processed products to the final processed product W2 in multiple steps (three steps in this example).
  The transfer press P of the present embodiment is a lifting and lowering motor for a slide 13 that is continuously operated. The transfer press P horizontally moves the rack 20 via the conversion mechanisms of the racks 16 and 20 and the pinion 18 and is fixed to the rack 20. On the other hand, the conveyance unit 30 (including the conveyance bar 40) in an initial state that is so-called intermittently driven conveys the above-mentioned processed products in a pitch manner. That is, in this embodiment, since the power source of the transport unit 30 is raised and lowered of the slide 13 that performs continuous press operation, a separate transport motor is not required.
  Further, in the present embodiment, the transport unit 30 intermittently contacts the transport bar 22 of the transport unit 30 with respect to the transport base 22 fixed to the rack 20 of the conversion mechanism, so that the transport unit 30 intermittently causes the above-described processed products. Therefore, a synchronization mechanism (for example, a servo motor and a substrate) that synchronizes with a lifting motor (not shown) is not necessary. Therefore, according to the present embodiment, the above-described transport motor, the synchronization mechanism, and the like other than the lifting / lowering motor (not shown) of the slide 13 may be unnecessary, so that the configuration becomes simpler than the conventional one.
  Therefore, according to the present embodiment, since the driving source for performing the press processing in the molds 10 to 12 and 14 and the like and the pitch conveyance of those processed products can be made common, the above-described tuning mechanism can be made unnecessary. Compared with, the configuration is simplified, and the equipment cost is reduced. And since it was set as the pitch conveyance mechanism mechanically intermittently driven with respect to the continuous driving | operation of press work, it becomes a workpiece conveyance synchronizing with SPM (number of strokes) of the slide 13, and productivity improves conventionally.
  In addition, although the raising / lowering amount and slide amount of the work fingers vary depending on the processed product (various products), the present invention can change the setting of the conveyance surface or bottom dead center of the conveyance unit, so that it can be appropriately adapted to various products. be able to. In this case, the number of molds and the like can be arbitrarily changed, and a corresponding transport unit is arranged. Moreover, the conveyance stand or conveyance bar of this invention can be changed into arbitrary structures, respectively.
