<Press drive mechanism>
1-3 is a figure which shows an example of the press drive mechanism 1 which concerns on embodiment. FIG. 1 is a front view of the press drive mechanism 1 as viewed from the −Y direction. FIG. 2 is a side view of the press drive mechanism 1 as viewed from the −X direction. FIG. 3 is a perspective view of the press drive mechanism 1. In FIGS. 2 and 3, description of a cable protection member 36 to be described later is omitted. As shown in FIGS. 1 to 3, the press drive mechanism 1 includes a frame 2, a ram support 3, a ram support guide 4, a ram 5, a tool support guide 27, a tool support 6, A coupling mechanism 7, a detection unit 8, and a lower mold support 9 are provided. The press drive mechanism 1 drives a press tool 10 for processing a plate-like workpiece W.

  The frame 2 includes a vertical frame 2a and a horizontal frame 2b. The vertical frame 2a is a plate-like member that stands up and down and extends in the X direction. The vertical frame 2a is formed of a single metal member, and the material, the plate thickness, and the like are set so as to have sufficient strength for pressing. The vertical frame 2 a supports each part of the press drive mechanism 1. Moreover, the opening part 12 is provided in the vertical frame 2a. In addition to the workpiece W, the opening 12 is formed so as to be able to pass through a part of a conveying device 51 described later and a fork device 65. The vertical frame 2a is not limited to being a single metal member. For example, it may be constituted by a plurality of plate-like members, or may be constituted by combining a plurality of rod-like members.

  The horizontal frame 2b is formed extending in the horizontal direction from the vertical frame 2a. The horizontal frame 2b is provided on the −Y side above the vertical frame 2a. The horizontal frame 2b is a plate-like member extending in the X direction and the Y direction. As described above, when the vertical frame 2a is a plate-like member and the horizontal frame 2b is formed extending from the vertical frame, the press drive mechanism can be supported with a compact and sufficient strength. The horizontal frame 2b supports a ram support 3 described later in a suspended state.

  The oblique rib 13 connects the end of the horizontal frame 2b and the upper part of the vertical frame 2a. The oblique ribs 13 are fixed to the vertical frame 2a by welding or bolts at the ends of the horizontal frame 2b, and improve the strength of the horizontal frame 2b. The oblique ribs 13 are arranged on the upper side of the vertical frame 2a. The oblique rib 13 is a plate-like member, is disposed in a state inclined with respect to the vertical direction (Z direction), and is also inclined with respect to each of the vertical frame 2a and the horizontal frame 2b. In addition, although the 1st plate-shaped member is used for the diagonal rib 13 over the X direction of the horizontal frame 2b, it is not limited to this, You may form partially in the X direction of the horizontal frame 2b. Moreover, although the angle with respect to the up-down direction of the diagonal rib 13 is arbitrary, it is set in the range of 30 to 60 degrees, for example.

  A cable protection member 15 that accommodates a power cable or the like is disposed on the upper surface of the oblique rib 13. The cable protection member 15 accommodates a power cable or the like that has one end connected to an elevating drive unit 18 and the like that will be described later, and the other end fixed to the upper surface of the oblique rib 13 and connected to the elevating drive unit 18 and the like. The cable protection member 15 accommodates piping and the like in addition to the power cable. The cable protection member 15 can be deformed following the movement of the elevating drive unit 18 or the like in the X direction.

  In the present embodiment, since the horizontal frame 2 b is reinforced by the oblique ribs 13, the planar upper surface of the oblique ribs 13 can be used effectively as an arrangement place of the cable protection member 15. A space in the X direction surrounded by the oblique rib 13, the vertical frame 2a, and the vertical frame 2a is formed below the oblique rib 13. This space can be used as a housing space for various components.

  The ram support guide 4 guides the ram support 3 described later. The ram support guide 4 is formed along the X direction at the lower part of the horizontal frame 2b. The ram support guide 4 supports the upper portion of the ram support 3 and guides the ram support 3 in the X direction. The ram support guide 4 is disposed so as to be almost directly above a machining axis AX2 of the ram 5 described later. Thereby, the reaction force generated in the press working can be efficiently received by the ram support body guide 4. Two or more ram support guides 4 may be arranged. When a plurality of ram support guides 4 are arranged, any one of them may be arranged almost directly above the machining axis AX2, and the plurality of ram support guides 4 are arranged with the machining axis AX interposed therebetween, You may make it receive reaction force with good balance.

  The ram support 3 includes a frame 17, an elevating drive unit 18, and a ram support unit 24. The frame 17 supports an elevating drive unit 18 that drives the ram 5. The frame 17 includes a vertical portion 17a and a horizontal portion 17b. The vertical portion 17a is formed along the vertical frame 2a, and the horizontal portion 17b is formed extending from the upper portion of the vertical portion 17a in the Y direction. The vertical portion 17 a is connected to the ram support guide 4, and guides the ram support 3 in the X direction while being suspended from the ram support guide 4. Since the ram support 3 is suspended from the ram support guide 4, for example, the ram support 3 can be made compact as compared with guiding on the side of the ram 5.

  The elevating drive unit 18 raises and lowers the ram 5. The lift drive unit 18 includes a drive device 19 and a drive force transmission unit 20. Since the ram support 3 includes the lifting / lowering drive unit 18, the mechanism can be made compact compared to installing the lifting / lowering drive unit 18 in another part. For example, an electric motor is used as the driving device 19. The driving device 19 is supported on the −Y side on the upper surface of the lateral portion 17b.

  The driving force transmission unit 20 includes a belt 21 and a ball screw 22. The belt 21 is stretched over the ball screw 22 from the driving device 19 and transmits the driving force of the driving device 19 to the ball screw 22. The ball screw 22 is disposed along the vertical direction. The upper end portion of the ball screw 22 is supported by the vertical portion 17 a via the support member 23. A nut (not shown) is connected to the ball screw 22. The nut is moved up and down by the rotation of the ball screw 22. A ram 5 is attached to the nut, and the ram 5 is raised and lowered by raising and lowering the nut. In addition, the raising / lowering drive part 18 will not be limited to the mechanism which has the above-mentioned ball screw 22, if the ram 5 is raised / lowered. For example, the lifting drive unit 18 may be an actuator such as a hydraulic cylinder device or a pneumatic cylinder device.

  The ram 5 is driven to drive a press tool 10 described later. The ram 5 is formed in a cylindrical shape, and is moved up and down along the lifting axis AX1 by the lifting drive unit 18. The raising / lowering axis AX1 substantially coincides with the longitudinal axis of the ball screw 22. The lift axis AX1 is a vertical axis. When the ram 5 is lowered and the press tool 10 is lowered, press work (forming process or punching process) on the workpiece W is performed. The lower end portion of the ram 5 is formed corresponding to the upper end portion of the press tool 10 described later. Thereby, when the ram 5 descends, the ram 5 and the press tool 10 can be accurately connected.

  The ram support 24 supports the ram 5. The ram support 24 is provided on the −Y side of the vertical portion 17a. The ram support 24 is connected to the vertical portion 17a via a vertical guide 25 provided on the vertical portion 17a, and is movable in the vertical direction with respect to the vertical portion 17a. The guides 25 are disposed on the + X side and the −X side of the ram support 24. The ram support 24 moves in the vertical direction as the ram 5 moves up and down.

  Note that the ram 5 receives an upward reaction force during the press working. In the present embodiment, since the ram 5 moves up and down along the lifting axis AX1 set substantially below the ram support guide 4, the reaction force of the press tool 10 is received by the ram support guide 4, which is simple. By accurately driving the press tool 10 with a simple configuration, the machining accuracy for the workpiece W can be improved. Further, since the reaction force is received, a complicated configuration is unnecessary, and the mechanism can be made compact.

  The tool support guide 27 guides the tool support 6 described later. Two tool support guides 27 are formed vertically along the direction (X direction) parallel to the moving direction of the ram support 3 below the ram support 3 of the vertical frame 2a. In addition, the tool support body guide 27 may be one, and may be three or more.

  The tool support 6 can support a plurality of press tools 10. The press tool 10 is, for example, an upper die in press work. The tool support 6 is formed in an L shape having a vertical portion 28 and a lower portion 29. The vertical portion 28 is formed to extend in the vertical direction. The lower portion 29 is formed to extend laterally (Y direction) from the lower portion of the vertical portion 28. The lower portion 29 can support the plurality of press tools 10 along the X direction. Since the tool support 6 is formed in an L shape including the vertical portion 28 and the lower portion 29, the plurality of press tools 10 can be stably supported with a simple configuration.

  The lower portion 29 supports the lower end portion of the press tool 10 so as to protrude downward from the lower portion 29 when any of the press tools 10 is lowered by the ram 5. Each press tool 10 is connected to the elastic member 31 via a support member (not shown). The elastic member 31 elastically supports each press tool 10, and each press tool 10 descends while compressing the elastic member 31. Therefore, each press tool 10 is raised to the original position by the elastic force of the elastic member 31 when the ram 5 is raised.

  A length L1 from the vertical portion 28 to the machining axis AX2 of the press tool 10 in the lower portion 29 is set to be shorter than the vertical length L2 of the vertical portion 28. The processing axis AX2 is an axis on which the press tool 10 performs press processing. The processing axis AX2 is substantially coaxial with the lifting axis AX1. Since the length L1 is set shorter than the length L2 as described above, the strength of the lower portion 29 that supports the press tool 10 can be improved, and the press tool 10 can be driven stably. Further, since the machining axis AX2 is closer to the vertical frame 2a having high rigidity, the driving accuracy of the press tool 10 can be improved.

  The + Y side of the vertical portion 28 is connected to the tool support guide 27. The tool support 6 is movable in the X direction along the tool support guide 27. The tool support 6 includes a travel drive unit 35 that drives the tool support 6, and travels in the X direction along the tool support guide 27 by the travel drive unit 35. For example, an electric motor is used as the travel drive unit 35. The tool support 6 can support a plurality of press tools 10 along the moving direction, and includes a travel drive unit 35 on an extension line in which the plurality of press tools 10 are arranged. Thereby, it is possible to prevent the travel drive unit 35 from protruding from the tool support 6 in the Y direction, and it is possible to make the travel drive unit 35 more compact as compared to arranging the travel drive unit 35 elsewhere. By moving the tool support 6, any one of the plurality of press tools 10 can be easily selected with respect to the lift axis AX <b> 1 of the ram 5.

  The traveling drive unit 35 is disposed away from the maintenance region M side of the tool support 6 (see FIG. 3). In the present embodiment, the maintenance area M is set on the −X side of the vertical frame 2 a, and the traveling drive unit 35 is disposed on the + X side of the tool support 6. Thereby, it is possible to prevent the traveling drive unit 35 from being disturbed during maintenance such as replacement of the press tool 10 with respect to the tool support 6.

  The lower portion 29 and the ram support 3 are connected by a cable protection member 36 (see FIG. 1). As a result, power is supplied to the travel drive unit 35 via a power cable or the like housed in the cable protection member 36. The power supply to the travel drive unit 35 is not limited to being via the ram support 3 and may be performed from another location. Note that the tool support 6 and the ram support 3 are connected by a cable protection member 36, and the relative movement between the two is within a deformable range of the cable protection member 36.

  The coupling mechanism 7 has a plurality of holes 38 and pins 39. The plurality of holes 38 are provided in the tool support 6. The plurality of holes 38 are provided in the tool support 6 corresponding to the plurality of press tools 10. For example, as shown in FIG. 1, the hole 38 a among the plurality of holes 38 corresponds to the press tool 10 a among the plurality of press tools 10. The hole 40 does not correspond to the press tool 10 and is disposed on the + X side of the tool support 6. The hole 40 is used when the tool support 6 is traveling. The pin 39 is provided below the ram support 3 and can be inserted into any of the plurality of holes 38. The pin 39 can be inserted into the hole 40. The pin 39 is formed to be movable in the Y direction. The pin 39 is moved in the −Y direction by a pin driving unit 41 provided on the ram support 3 and is inserted into any of the holes 38. The connection mechanism 7 connects the tool support 6 and the ram support 3 by inserting the pin 39 into any of the plurality of holes 38. When the connection mechanism 7 connects the tool support 6 and the ram support 3, both the tool support 6 and the ram support 3 can be moved by driving the traveling drive unit 35. Thereby, the drive part for moving the ram support body 3 separately becomes unnecessary, and the ram support body 3 can be made compact, reducing cost.

  The connection mechanism 7 connects the tool support 6 and the ram support 3 with the desired press tool 10 selected by inserting the pin 39 into any of the plurality of holes 38. First, the travel drive unit 35 is driven with the pin 39 removed from the hole 38, and the tool support 6 is moved with respect to the ram support 3. Subsequently, the traveling drive unit 35 is stopped in a state where the lifting shaft AX1 of the ram 5 is set to the desired press tool 10a, and the pin drive unit 41 is driven to insert the pin 39 into the corresponding hole 38a. The desired press tool 10a is selected by the above procedure. As described above, the coupling mechanism 7 can efficiently select any of the plurality of press tools 10 with a simple configuration by selecting a coupling portion using the plurality of holes 38 and the pins 39. In the above description, the hole 38 is provided in the tool support 6 and the pin 39 is provided in the ram support 3. However, the present invention is not limited to this. The pin 39 is provided in the tool support 6 and the ram support is provided. A hole 38 may be provided in the body 3.

  The detection unit 8 detects which one of the plurality of press tools 10 has been selected. The detection unit 8 includes an object to be detected (dog) 8a, a proximity sensor 8b, and a reed switch 8c. The detected object 8 a is provided below each hole 38. The proximity sensors 8b are provided at three positions so as to be arranged in the X direction at a predetermined interval below the pin driving unit 41, and can detect the proximity of the detected object 8a without contact. The reed switch 8c is provided in a part of the pin driving unit 41 such as a cylinder device, for example, and can detect the protrusion of the pin 39.

  4A and 4B are diagrams illustrating an example of the detection unit 8, in which FIG. 4A is a diagram viewed from the −Y direction, FIG. 4B is a plan view, and FIG. 4C is a diagram illustrating a pattern of the detection target 8a. In the example shown in FIGS. 4A and 4B, three detected bodies 8a are provided side by side in the X direction at intervals corresponding to the three proximity sensors 8b. Further, as shown in FIGS. 4A and 4B, the detected object 8 a is provided so as to protrude in the −Y direction from the vertical portion 28 below each hole 38. Accordingly, when the proximity sensor 8b moves in the −X direction as shown in FIG. 4A and reaches the lower portion of the hole 38 as shown in FIG. 4B, each proximity sensor 8b is detected. The three detected bodies 8a are detected by approaching the body 8a.

  The detected object 8a is provided with a unique pattern in each hole 38. The pattern is determined depending on whether or not the detected object 8a is provided at each of the three positions that can face the three proximity sensors 8b. When the detection target 8a can be arranged at three places, as shown in FIG. 4C, eight types of patterns P1 to P8 can be used. These patterns P <b> 1 to P <b> 8 are provided below any one of the hole portions 38. When the three proximity sensors 8b reach below the hole 38, the holes 38 are identified by the patterns P1 to P8 (depending on the presence or absence of the three detected objects 8a).

  Further, when the pin 39 is driven by the pin drive unit 41, it is detected that the pin 39 is inserted into the hole 38 by the reed switch 8c. As described above, the detection unit 8 detects which hole 38 among the plurality of holes 38 the pin 39 is inserted by identifying the hole 38 and detecting the drive of the pin 39. By confirming the detection result of the detection unit 8, the selected press tool 10 can be easily recognized. The detection unit 8 is not limited to the configuration described above. For example, the detected object 8a and the proximity sensor 8b may be two each, or may be four or more. Moreover, the detection part 8 is not limited to the structure provided with the to-be-detected body 8a, the proximity sensor 8b, and the reed switch 8c, The arbitrary detection mechanism which can identify the selected press tool 10 can be used. However, whether or not the detection unit 8 is provided is arbitrary.

  Returning to FIGS. 1 to 3, the lower mold support guide 42 guides the lower mold support 9 described later. The lower die support guides 42 are provided on the upper surface of the support member 43 extending in the −Y direction from the lower portion of the vertical frame 2a, and two lower guide guides 42 are formed along the X direction. The number of lower mold support guides 42 may be one, or three or more.

  The lower mold support 9 can support a plurality of lower molds 44 as press tools. The lower mold support 9 is guided in the X direction by the lower mold support guide 42. The lower mold support 9 includes a driving device 45 and is movable in the X direction. As the driving device 45, for example, an electric motor or the like is used. The lower mold support 9 supports a plurality of lower molds 44 along the movement direction (X direction). As the lower mold support 9 moves in the X direction, a plurality of lower molds 44 to be used for pressing are selected. The plurality of lower molds 44 may be arranged side by side corresponding to the plurality of press tools 10. The driving device 45 is arranged away from the maintenance area M. Thereby, it is possible to prevent the driving device 45 from being disturbed during maintenance such as replacement of the lower mold 44 in the lower mold support 9.

  Each part of the press drive mechanism 1 is controlled by a control unit (not shown). The control unit includes a central processing unit (CPU), a storage device such as a memory and a hard disk, programs necessary for various controls, and the like. The control unit controls, for example, the travel of the ram support 3, the travel of the tool support 6, the travel of the lower mold support 9, the operation of the elevating drive unit 18, and the operation of the coupling mechanism 7.

  Next, the operation of the press drive mechanism 1 will be described. 5 and 6 are diagrams showing an example of the operation of the press drive mechanism 1. FIG. However, the following description is an example and does not limit the operation of the press drive mechanism 1. When performing the press working, as shown in FIG. 5A, the tool support 6 and the ram support 3 travel in the X direction by driving of the travel drive unit 35 in a state of being connected by the connecting mechanism 7, The lifting axis AX1 of the ram 5 is aligned with a predetermined position of W. In FIG. 5A, the pin 39 is inserted into the hole 40, and the press tool 10 is not selected. Below, the case where the press tool 10b is selected from the plurality of press tools 10 will be described as an example.

  First, the connection between the tool support 6 and the ram support 3 is released by removing the pin 39 from the hole 40. This release is detected by a reed switch 8c (see FIG. 2) of the detection unit 8. Subsequently, as shown in FIG. 5B, the traveling drive unit 35 is driven to move only the tool support 6 in the + X direction, and the lifting shaft AX1 is stopped in accordance with the press tool 10b. By inserting the pin 39 into the hole 38b at this position, the tool support 6 and the ram support 3 are connected with the press tool 10b selected. At this time, the elevating axis AX1 of the ram 5 and the machining axis AX2 of the press tool 10b are substantially coaxial. The same applies when another press tool 10 is selected. The insertion of the pin 39 into the hole 38b is detected by the reed switch 8c of the detection unit 8, and the proximity sensor 8b of the detection unit 8 detects that the press tool 10b has been selected.

  Subsequently, as shown in FIG. 6A, the lower mold support 9 travels by the driving device 45, and the lower mold 44 corresponding to the press tool 10b is stopped according to the machining axis AX2. This stop position is detected by a detection device (not shown). The lower mold support 9 may be run and stopped while the tool support 6 and the ram support 3 are running, or may be performed while the press tool 10 is selected.

  Subsequently, as shown in FIG. 6B, the elevating drive unit 18 is driven to lower the ram 5 along the elevating axis AX1. When the ram 5 is lowered, the press tool 10 b is lowered, and a predetermined portion of the workpiece W is pressed by the press tool 10 b and the lower mold 44. After the press working, the lift drive unit 18 is driven to raise the ram 5 so that the press tool 10b is raised by the elastic member 31 and returned to the original position. By repeating the above operation, it is possible to perform press working at a plurality of locations on the workpiece W. In that case, the press tool 10 can be easily changed according to a process location.

  As described above, according to the present embodiment, the ram 5 moves up and down along the lifting axis AX1 set substantially below the ram support 3 guide, so that the reaction force of the press tool 10 is generated by the ram support guide 4. Therefore, the machining accuracy for the workpiece W can be improved by driving the press tool 10 with a simple configuration with high accuracy. Further, since the ram support guide 4 is set above the ram 5 and the reaction force of the press tool is received by the ram support guide, a complicated configuration is not required to receive the reaction force, and the mechanism is made compact. be able to.
