[0001] This application is a divisional application of invention patent application 201910221054.3.

[0002] This application incorporates the content of Japanese Patent Application No. 2018-056929 filed on March 23, 2018 Technical Field

[0003] The present invention relates to a servo press and a method for setting up a servo press. Background Art

[0004] In the past, the setting of the slide movement in the servo press was, for example, to show the ratio of the slide speed to the slide position in the form of a table, and the setting was performed by entering the numerical values ​​of each column in the table (see Patent Publication No. 2014-54642, Patent Publication No. 2004-58152, and Patent Publication No. 2003-260599).

[0005] The problem is that the slider movement caused by such movement settings is difficult for the operator to intuitively feel. Because the previous table-based movement setting interface relies on the operator's imagination of the input results, there is a possibility that the settings are different from what is intended. Summary of the Invention

[0030] The present invention is made to solve at least a part of the above-mentioned problems, and can be realized as the following application examples.

[0031] [Application Example 1]

[0032] The servo press involved in this application example is a servo press that converts the rotation of a servo motor into a reciprocating linear motion of a slider through an eccentric mechanism that converts rotational motion into linear motion and performs stamping processing, and is characterized in that it includes: a display unit, which displays a strip area for setting the movement of the slider; and an operating unit, which receives an input operation; the extension range of the strip area from the upper end to the lower end corresponds to the movement range of the slider in the linear motion; the strip area is formed by a plurality of slider action areas continuous in the extension direction of the strip area; the speed of the slider can be set separately for the slider action area according to the input operation to the operating unit; the boundary of the adjacent slider action area can be moved along the extension direction of the strip area according to the input operation to the operating unit.

[0033] With the servo press of this application example, the slider's linear motion range is indicated by a band-like area, allowing the operator to set the slider's motion while visually recognizing the set slider's motion. Furthermore, the slider's speed can be set for each of the multiple slider motion areas while the boundaries of the slider motion areas are moved. This allows the operator to perform input operations while visually recognizing the slider's motion, thereby improving operability.

[0034] [Application Example 2]

[0035] In the servo press according to the above application example, the band-shaped area is a ring-shaped image corresponding to the rotational operation of the eccentric mechanism, and a plurality of arc-shaped slider operation areas can be arranged to form a ring.

[0036] According to the servo press of this application example, since the band-shaped area is provided as a donut-shaped image corresponding to the rotational motion of the crankshaft of a normal eccentric mechanism, the operator can easily visually recognize the movement of the slider, thereby improving operability.

[0037] [Application Example 3]

[0038] In the servo press involved in the above-mentioned application example, the strip area may include in the initial state: two slider action areas arranged between the top dead center and the bottom dead center corresponding to the forward rotation action of the eccentric mechanism, and one slider action area arranged between the bottom dead center and the top dead center.

[0039] According to the servo press machine of this application example, by setting the common motion among the motions of the slide caused by the normal rotation operation of the eccentric mechanism as the initial state of the band-shaped region, the operator can easily set the motion of the slide.

[0040] [Application Example 4]

[0041] In the servo press involved in the above-mentioned application example, the strip area includes two upper and lower slider action areas corresponding to the pendulum action of the eccentric mechanism in the initial state; the upper slider action area can be the range where the slider does not move.

[0042] According to the servo press of this application example, by setting the common motion among the motions of the slide caused by the pendulum action of the eccentric mechanism as the initial state of the band-shaped region, the operator can easily set the motion of the slide.

[0043] [Application Example 5]

[0044] In the servo press involved in the above-mentioned application example, the strip area is a strip-shaped image, the two ends of the image are at positions far away from each other, and extend downward from one of the two ends and turn upward at the lower end to reach the other end; the two ends correspond to the rising limit value of the slider; the lower end corresponds to the falling limit value of the slider; the lower end may have at least one slider action area extending in the horizontal direction.

[0045] According to the servo press of this application example, by using such an image of the band-shaped area, the operator can set the movement while visually recognizing the movement of the slide that temporarily stops the slide at the bottom dead center.

[0046] [Application Example 6]

[0047] In the servo press involved in this application example, the strip-shaped area is two adjacent strip-shaped images, one end of each image corresponds to the rising limit value of the slider, and the other end corresponds to the reversal point where the slider rises after passing the falling limit value; the two strip-shaped images can be combined so that the other ends are adjacent to each other.

[0048] According to the servo press of this application example, by using such an image of a band-shaped area, the operator can set the movement while visually recognizing the movement of the so-called double-stroke slide.

[0049] [Application Example 7]

[0050] In the servo press according to the above-mentioned application example, the number of the slide operation areas of the band-shaped area can be increased or decreased according to an input operation to the operation unit.

[0051] With the servo press of this application example, more complex motions can be set by increasing or decreasing the area of ​​the slide.

[0052] [Application Example 8]

[0053] In the servo press according to the above-described application example, the speed of the slide in the slide operation area can be set by changing the width of the slide operation area according to the input operation to the operation unit.

[0054] With the servo press of this application example, by making the width of the slide motion area correspond to the slide setting speed, the operator can set the movement while visually recognizing the change in speed.

[0055] [Application Example 9]

[0056] In the servo press according to the above-described application example, the slide operating region in which the amplitude is changed may be a region having the lower end as one end.

[0057] According to the servo press machine of this application example, since the slide motion region in which the amplitude is changed is the region having the lower end of the band-shaped region as one end, a unique pressing motion near the bottom dead center can be provided.

[0058] [Application Example 10]

[0059] The servo press according to the application example further includes a storage unit storing a plurality of the band-shaped areas; and the display unit can select and display any one of the plurality of band-shaped areas from the storage unit in response to an input operation on the operation unit.

[0060] According to the servo press machine of this application example, by preparing a plurality of band-shaped areas in advance in the storage unit, it is possible to flexibly cope with various motion settings.

[0061] [Application Example 11]

[0062] In the servo press according to the above application example, the operating unit may be provided on the display unit, and the input operation to the operating unit may be a touch operation.

[0063] According to the servo press according to this application example, operability is improved by performing input through touch operation.

[0064] [Application Example 12]

[0065] The setting method of the servo press involved in this application example is a setting method of the servo press that converts the rotation of the servo motor into the reciprocating linear motion of the slider through an eccentric mechanism that converts the rotational motion into the linear motion and performs stamping processing. It is characterized in that: by inputting an operation on a strip-shaped area displayed on a display unit, the boundaries of multiple slider action areas set on the strip-shaped area for setting the speed of the slider are moved, and the height range of the slider that moves according to the speed set on each of the slider action areas is set.

[0066] By using the setting method of the servo press involved in this application example, the height range of the slider corresponding to the slider movement area can be set by moving within the boundary of the slider movement area where the slider speed is set, so that the operator can set the movement while visually identifying the movement of the slider after setting.

[0067] With the servo press according to one embodiment of the present invention, an operator can set the movement while visually recognizing the movement of the slide after setting. Furthermore, with the setting method for a servo press according to one embodiment of the present invention, an operator can set the movement while visually recognizing the movement of the slide after setting.

[0068] The following drawings illustrate embodiments applicable to the present invention in detail. Furthermore, the embodiments described below do not unduly limit the scope of the present invention as set forth in the claims. Furthermore, the structures described below are not necessarily essential components of the present invention.

[0069] 1. Overview of Servo Press

[0070] use Figures 1 to 3 The outline of a servo press (hereinafter referred to as "press 1") will be described. Figure 1 This is a front view showing the entire press machine 1 according to one embodiment of the present invention. Figure 2 This is a block diagram of the operating panel 20 of the press machine 1. Figure 3 It is a front view of the operation panel 20 of the press machine 1.

[0071] like Figure 1 As shown, the press machine 1 converts the rotation of the servo motor 7 into a reciprocating linear motion of the slide 3 by means of an eccentric mechanism 4 that converts the rotational motion into the linear motion, thereby performing a punching process.

[0072] The press machine 1 includes an eccentric mechanism 4 having a crankshaft 5 and a connecting rod 6 , a servo motor 7 driving the eccentric mechanism 4 , a speed reducer 8 connecting the eccentric mechanism 4 and the servo motor 7 , and an operation panel 20 for performing various settings and operations of the press machine 1 .

[0073] The servo motor 7 is an AC servo motor. The servo motor 7 is not limited to an AC servo motor, and an induction motor, a reluctance motor, a DC servo motor, etc. can be used.

[0074] The eccentric mechanism 4 is not limited to a crank mechanism using a crankshaft 5; a crank mechanism with an eccentric shaft can also be used. Furthermore, the eccentric mechanism 4 can be a known slider drive mechanism used in presses 1, such as a knuckle mechanism or a connecting rod mechanism forming a force-amplifying mechanism. Furthermore, a mechanism with an eccentric plate integral with the main gear can also be used. The crankshaft 5 is driven by a servo motor 7 and rotates between a top dead center 70 (shown by the dashed line in the figure) and a bottom dead center 72.

[0075] The mold is fixed on the pad 2 and the slider 3 respectively. The slider 3 connected to the lower end of the connecting rod 6 is driven by the servo motor 7 to rotate the crankshaft 5 and rise and fall relative to the pad 2. The vertical movement range 10 of the slider 3 is the lift limit 11 ( Figure 1 The range between the lower limit value 12.

[0076] The operation panel 20 includes a display unit 22 that displays a band 30 for setting the movement of the slide 3, and an operation unit 60 that receives input operations. The operation panel 20 is mounted on the press 1 and electrically connected thereto. The operation panel 20 is a device used by an operator of the press 1 to perform various settings and operations on the press 1.

[0077] The display unit 22 is a liquid crystal display (LCD). Other known display devices (such as organic EL (Electro Luminescence)) can also be used as the display unit 22. The display unit 22 can display various user interfaces (GUIs (Graphical User Interfaces)) used by the operator.

[0078] The operating unit 60 is provided on the display unit 22. The operating unit 60 is a touch screen type that is provided integrally with the display unit 22, and input operations to the operating unit 60 can be performed by touch operations. The operator can change the displayed image 24 by inputting to the operating unit 60 on the display unit 22 through touch operations, thereby increasing operability. The touch screen type allows the operating unit 60 to be operated by directly touching the display unit 22 with a finger or a pen. As a touch screen, a touch screen of a known type such as a resistive film type, an electrostatic capacitance type, a surface type electrostatic capacitance type, a projection type electrostatic capacitance type, etc. can be used. The operating unit 60 is not limited to a touch screen type that is integrated with the display unit 22, as long as it can perform operations such as changing the image 24 displayed on the display unit 22. Specifically, it can be a face screen that can be attached and detached relative to the display unit 22, or a known input device (such as a mouse, a trackball, a keyboard, etc.) that is provided independently of the display unit 22.

[0079] The operation panel 20 includes a second operation unit 61 on which physical keys operated by the operator are arranged. The second operation unit 61 includes an input device operable instead of the touch-screen operation unit 60 and an input device for operations other than the operation unit 60 .

[0080] like Figure 2 As shown, the operation panel 20 includes a calculation unit 62 and a storage unit 64 electrically connected to the display unit 22 and the operation unit 60 .

[0081] The calculation unit 62 is a CPU (Central Processing Unit) that performs stamping processing by executing programs stored in the storage unit 64. Furthermore, the calculation unit 62 can set the movement of the slide 3 according to the operator's operation of the operation unit 60 and the second operation unit 61, and can also change the movement of the slide 3 pre-stored in the storage unit 64.

[0082] The storage unit 64 stores programs and configuration data for the press machine 1, such as the motion data of the slide 3. The motion of the slide 3 can be represented by a motion curve for one cycle of the slide 3. Typically, the vertical axis represents the slide 3's position (slide 3's stroke) (mm), and the horizontal axis represents the cycle time (seconds). The calculation unit 62 outputs commands to the servo motor 7 based on the motion data stored in the storage unit 64. The servo motor 7 drives according to these commands, causing the slide 3 to move according to the preset motion.

[0083] like Figure 3 As shown, the operation panel 20 includes a display unit 22 and an operation unit 60 at the center of the front surface, and a second operation unit 61 below the display unit 22. The display unit 22 displays an image 24 including a band-shaped area 30.

[0084] The extension range of the band-shaped region 30 from the upper end 31 to the lower end 32 corresponds to the moving range 10 of the slider 3 in the linear motion. Thus, the upper end 31 corresponds to the top dead center 70 of the crankshaft 5, and the lower end 32 corresponds to the bottom dead center 72 of the crankshaft 5 ( Figure 1 The upper end 31 of the band-shaped region 30 indicates the rotation angle of the crankshaft 5 as "0°," while the lower end 32 indicates the rotation angle as "180°." Furthermore, the width of the band-shaped region 30 corresponds to the speed of the slider 3, and the maximum width W of the band-shaped region 30 indicates the maximum speed of the slider 3. The speed of the slider 3 is the target speed, and the operating panel 20 issues a command to the servo motor 7 to move the slider 3 at that speed.

[0085] The strip-shaped area 30 is composed of a plurality of slider action areas ( Figure 3 The first slider motion area 41, the second slider motion area 42, and the third slider motion area 43 are formed during forward rotation. By indicating the linear motion range 10 of the slider 3 as a band-shaped area 30, the operator can set the motion while visually recognizing the set motion of the slider 3. Furthermore, the speed of the slider 3 can be set for each of the slider motion areas (41, 42, 43) based on input operations on the operating unit 60.

[0086] The boundaries (first boundary 51, second boundary 52, third boundary 53) of adjacent slider operation areas (first slider operation area 41 and second slider operation area 42, second slider operation area 42 and third slider operation area 43, and third slider operation area 43 and first slider operation area 41) can be moved along the extension direction of the strip area 30 in response to an input operation on the operation unit 60. By enabling the speed of the slider 3 to be set for each slider operation area (41, 42, 43) and by enabling the boundaries (51, 52, 53) of the slider operation areas (41, 42, 43) to be moved, an operator can perform input operations while visually recognizing the movement of the slider 3, thereby improving operability.

[0087] The band-shaped area 30 is an annular image corresponding to the rotational motion of the eccentric mechanism 4. The band-shaped area 30 is a plurality of arc-shaped slider motion areas ( Figure 3 The first slider action area 41, the second slider action area 42, and the third slider action area 43 are arranged in a circular ring. By providing the band-shaped area 30 with a circular image corresponding to the rotational movement of the eccentric mechanism 4, the operator can easily visually recognize the movement of the slider 3, thereby improving operability. The band-shaped area 30 is not limited to a circular ring; other shapes (such as a straight line extending vertically or horizontally, a V-shape, or a U-shape) may be used.

[0088] The display unit 22 can display images other than the strip-shaped area 30. For example, there is a method of expressing operation buttons as images.

[0089] 2. Forward rotation

[0090] use Figures 4 to 11 The operation of setting the movement of the slider 3 corresponding to the normal rotation operation of the eccentric mechanism 4 will be described. Figures 4 to 7 2 is a diagram showing an image 24 of a forward rotation operation displayed on a display unit 22 of the press machine 1. Figure 8 FIG. 1 is a diagram for explaining the operation of dividing the strip area 30 displayed on the display unit 22 of the press machine 1. Figure 9 and Figure 10 This is a diagram showing the movement of the slide 3 during the forward rotation of the press machine 1. Figure 11 This is a diagram illustrating a specific example of the movement of the slide 3 during the forward rotation operation of the press machine 1 .

[0091] like Figures 4 to 7 As shown, the display unit 22 displays the image 24 of the annular band area 30 and images of a plurality of buttons ( 26 a to 26 e ).

[0092] Figure 4The operator's finger 80 touches (clicks) the forward rotation selection button 26a to select the forward rotation movement, and the display unit 22 displays the image 24. The "basic SPM" displays the reference SPM (strokes per minute) of the slide 3 in the forward rotation movement of the press machine 1, and the "cycle SPM" displays the SPM on the displayed band 30.

[0093] Figure 4 The band-shaped area 30 shown is the image 24 of the initial state. The band-shaped area 30 includes two areas corresponding to the forward rotation of the eccentric mechanism 4, which are set at the top dead center 70 ( Figure 1 ) to bottom dead center 72( Figure 1 ), and a third slider action area 43 provided between the lower dead center 72 and the upper dead center 70. The second slider action area 42 is an area with the lower end 32 as one end. The slider action area 42 is an area with the lower end 32 of the strip area 30 as one end, thereby allowing a unique stamping motion to be provided near the lower dead center 72. As this unique stamping motion, for example, there is a function of reducing the impact when the upper mold and the workpiece come into contact with each other or preventing the product from jumping up due to pushing back the mold buffer gasket. The common motion in the motion of the slider 3 brought about by the forward rotation motion of the eccentric mechanism 4 is set as the initial state of the strip area 30, thereby allowing the operator to easily set the motion of the slider 3.

[0094] The upper end 31 of the band region 30 has a third border 53, which shows the height of the slider 3 ( Figure 1 The height of the rising limit 11 from the falling limit 12 is 200.0 mm, the lower end 32 has a second boundary 52, and the height of the display slider 3 is 0.0 mm.

[0095] The first slider action area 41 to the third slider action area 43 are displayed in different colors so that the operator can clearly identify each slider action area.

[0096] The first boundary 51 is located at a position 90 degrees from the upper end 31 along the annular band region 30 , indicating that the height of the slider 3 is 100.0 mm.

[0097] like Figure 5 As shown, if the operator moves (slides) finger 80 in the direction of the arrow while maintaining contact with first boundary 51, first boundary 51 moves in the direction extending from strip 30. As a result, first slider operation area 41 becomes longer and second slider operation area 42 becomes shorter. The position of first boundary 51 becomes 80.0 mm, and second slider operation area 42 is established starting at a position where the height of slider 3 is 80.0 mm. The following description focuses on the operation using the operator's finger 80, but other input devices such as a mouse may also be used.

[0098] exist Figure 4 In the initial state, the widths of all slider action areas (41, 42, 43) are displayed at their widest (matching the width of band area 30). The widths of the slider action areas (41, 42, 43) represent percentages of the target speed of slider 3 in each area. The target speed is the moving speed of slider 3, which is the target of control in the slider action areas (41, 42, 43). Therefore, the maximum width W represents the maximum speed (100%) of slider 3.

[0099] like Figure 6 As shown, when the operator moves (contracts) the finger 80 in the direction of the arrow while keeping in contact with the second slider operation area 42 to narrow the width, or moves (slides) the finger 80 toward the inner peripheral side while keeping in contact with the outer peripheral edge of the second slider operation area 42, the width W ( Figure 5 ) is narrowed to the changed amplitude W1. Furthermore, when the changed amplitude W1 is changed to the maximum amplitude W, it is widened or slid in the opposite direction. Here, the maximum amplitude W is reduced to 60% of the maximum speed. In this way, by changing the amplitude of the second slider action area 42 according to the input operation on the operation unit 60, the speed of the slider 3 on the second slider action area 42 can be set. The first slider action area 41 and the third slider action area 43 can also set the speed in the same way. By corresponding the amplitudes of the first slider action area 41 to the third slider action area 43 to the set speed of the slider 3, the operator can set the movement while visually recognizing the change in speed. In addition, it is not limited to changing the image of each amplitude, and the speed can also be displayed by displaying numerical information on each slider action area (41, 42, 43). When the finger 80 touches the operation button 26e, the operation unit 62 calculates the SPM of one cycle in which the speed of the slider 3 in the second slider action area 42 becomes 60%, and displays "48min -1 ”.

[0100] like Figure 7 As shown, not used Figure 6 The speed of the slider 3 on the second slider action area 42 can also be changed by inputting a percentage of the speed (e.g., "60") by displaying a keyboard on the display unit 22 after the finger 80 contacts the second slider action area 42.

[0101] like Figure 8As shown, when the operator touches split button 26c with finger 80, third slider action area 43 is split into fourth slider action area 44, as shown in the middle left section. Furthermore, fifth and sixth slider action areas 45 and 46 are displayed with each touch of split button 26c, with a maximum of six slider action areas being displayed, dividing strip area 30 into six equal parts. Similar to second slider action area 42, the speed of slider 3 can be set for each of first, third, and fourth to sixth slider action areas 44, 46.

[0102] Furthermore, if the operator touches the combination button 26d, Figure 8 The initial state of the upper right band area 30 is as follows Figure 8 As shown in the upper left corner, the second slider action area 42 disappears, and the first slider action area 41 and the third slider action area 43 are shown to divide the strip area 30 into two equal parts. Figure 8 The other strip regions 30 in the image may be subjected to an operation opposite to the segmentation operation.

[0103] In this way, the band area 30 can increase or decrease the number of slider action areas (41 to 46) according to the input operation to the operation unit 60. By increasing or decreasing the slider action areas (41 to 46), more complex motions can be set.

[0104] Figure 9 The dotted line shows the Figure 4 The forward motion curve 74a (slider 3 motion) of the slider 3 in the initial state of motion in the middle band region 30 is shown. The vertical axis represents the position of the slider 3 (mm), and the horizontal axis represents time (sec). For the forward motion curve 74a in the initial state, since the servo motor 7 rotates the crankshaft 5 at 100% speed, the sinusoidal trajectory of the slider 3 from the top dead center 70 of the crankshaft 5, through the bottom dead center 72, and back to the top dead center 70 again represents the target motion.

[0105] Figure 10 The dotted line shows Figure 6 The action curve 74b after the speed change. Figure 5 Lowering the first boundary 51, Figure 6 The speed of the second slider action area 42 is set to 60% of the movement of one cycle.

[0106] As described above, the press machine 1 operates based on the movement data of the slider 3 shown in the image 24 provided on the display unit 22 .

[0107] In this way, the operator of the press machine 1 can set the movement of the slide 3 while visually recognizing the stamping operation caused by the rotation of the crankshaft 5 by the servo motor 7 through the band-shaped area 30. Specifically, by replacing the upper end 31 of the donut-shaped image 204 with the top dead center 70 of the crankshaft 5 and the lower end 32 with the bottom dead center 72, the operator can visually recognize the rotation of the crankshaft 5 and set the movement of the slide 3.

[0108] use Figure 11 A specific example of setting the movement of the slider 3 will be described. Figure 11 In the strip area 30 of the middle image 24, by clicking the split button 26c, the third slider action area 43 is split and the fourth slider action area 44 is displayed at the lower end 32. Figure 11 The amplitude of the second slider action area 42 and the fourth slider action area 44 in the image 24 is changed. The movement of the slider 3 set in the strip area 30 of the image 24 is displayed as a segmented action curve 74c. Figure 11 Right side.

[0109] exist Figure 11 In the second slide motion region 42, the impact of the upper mold mounted on the slide 3 and the workpiece in the lower mold placed on the backing plate 2 on the slide 3 should be reduced. The lowering speed of the slide 3 is set to be reduced slightly before the start of processing. In this example, the speed is reduced to 50% of the maximum speed.

[0110] In the fourth slider action area 44 (between the second boundary 52 and the fourth boundary 54 of the lower end 32), the rising speed of the slider 3 is further reduced compared to the speed in the second slider action area 42. In this example, it is set to be reduced to 20% of the maximum speed. By setting it in this way, it is expected to prevent the product from jumping due to the push-back of the mold cushion or the product from being damaged due to contact with the mold. The so-called "product jumping" means that the rising action of the upper mold is slower than that at the bottom dead center 72 ( Figure 1 ) The push-back action of the mold buffer gasket near the upper mold causes the product to rise faster, and eventually a gap is instantly created between the upper mold and the product, causing the product to jump.

[0111] In order to prevent forming defects or reduction in processing output during stamping, the speed of the slider 3 near the bottom dead center 72 and the moving range of the slider 3 applicable to the speed ( Figure 11 The arrangement of the second slider action area 42 and the fourth slider action area 44 is important. Therefore, it is particularly preferable that the relationship between the position and speed of the slider 3 can be visually recognized as shown in the input interface such as the image 24.

[0112] 3. Pendulum action

[0113] use Figures 12 to 16The operation of setting the movement of the slider 3 corresponding to the pendulum motion of the eccentric mechanism 4 will be described. Figures 12 to 15 204 is a diagram showing an image of a pendulum motion displayed on the display unit 22 of the press machine 1. Figure 16 It is a diagram showing the movement of the slide 3 during the pendulum operation of the press machine 1 .

[0114] like Figure 12 As shown, when the operator touches (clicks) the pendulum motion selection button 26b with his finger 80, the pendulum motion is selected, and the display unit 22 displays the image 24. The pendulum motion is a motion in which the crankshaft 5 does not rotate to the top dead center 70 but rotates back and forth like a pendulum with the bottom dead center 72 as the center. If the pendulum motion is selected, since the slider 3 does not rise to the rising limit value 11 ( Figure 1 ) and the lowering movement, so the cycle time is shortened and the productivity of the press 1 is improved.

[0115] The strip region 300 of the image 204 displayed on the display unit 22 is Figure 12 The initial state includes two upper and lower first and second slider motion regions 401 and 402 corresponding to the pendulum motion of the eccentric mechanism 4. The upper first slider motion region 401 is a range where the slider 3 does not move. Specifically, the crankshaft 5 turns back at 90 degrees and 270 degrees corresponding to the first boundaries 501a and 501b, rotating only within the second slider motion region 402. Therefore, the slider 3 moves up and down only within the second slider motion region 402. By setting the common motion of the slider 3 caused by the pendulum motion of the eccentric mechanism 4 as the initial state of the band-shaped region 300, the operator can easily set the motion of the slider 3.

[0116] like Figure 13 As shown in FIG. 1 , when the finger 80 is moved (slid) in the direction of the arrow while contacting the first boundary 501a, Figure 12 The first boundary 501a, which is initially 100.0 mm, moves to 80.0 mm. At the same time, the first boundary 501b also moves to a height of 80.0 mm. Because the pendulum motion is the motion of the slider 3 in the second slider motion area 402, which moves back and forth at the same height. When the calculation button 26e is touched, the cycle SPM is calculated and displayed as "121 min -1 ”.

[0117] like Figure 14 As shown, when the finger 80 is moved (contracted) in the direction of the arrow while keeping in contact with the second slider operation area 402 to narrow the width, or is moved (slid) toward the inner peripheral side while keeping in contact with the outer peripheral edge of the second slider operation area 402, the maximum width W ( Figure 5) is narrowed to the changed amplitude W1. Here, the maximum reduction amplitude W is 60% of the maximum speed. When the operation button 26e is touched, the cycle SPM is calculated and displayed as "70min -1 ”.

[0118] like Figure 15 As shown, when finger 80 touches split button 26c, second slider action area 402 is split, and two third slider action areas 403 are displayed at both ends of second slider action area 402. If the maximum amplitude W of one of the two divided third slider action areas 403 changes, the amplitude of the other also changes. If the position of one second boundary 502a moves along the extension direction of band area 300, the other second boundary 502b also moves to the same height. The second slider action area 402 can be further subdivided.

[0119] like Figure 16 As shown, the initial state of the pendulum action curve 75a is represented by Figure 12 The movement of the slider 3 in the strip area 300 is shown in the action curve 75b after the pendulum stroke changes. Figure 13 The movement of the slider 3 is controlled by the band area 300. The movement range of the slider 3 is 10 Figure 12 The initial state is 0mm to 100mm in height, but Figure 13 After the change, the height is 0mm to 80mm. The time required for the second slider operation area 402 is also shortened by a corresponding amount.

[0120] In this manner, the operator of the press machine 1 can easily set the movement of the slide 3 while visually recognizing the pendulum motion of the servo motor 7 centered on the bottom dead center 72 of the crankshaft 5 through the band-shaped area 300 .

[0121] 4. Stop at bottom dead point

[0122] use Figures 17 to 19 The operation of setting the movement of the slide 3 for the bottom dead center stop operation will be described. Figure 17 and Figure 18 2 is a diagram showing an image 214 of a bottom dead center stop operation displayed on the display unit 22 of the press machine 1. Figure 19 1 and 2 are diagrams showing the movement of the slide 3 during the bottom dead center stop operation of the press machine 1 .

[0123] like Figure 17 As shown, when the operator touches (clicks) the bottom dead center stop operation selection button 26f with a finger 80, the bottom dead center stop operation is selected, and the display unit 22 displays an image 214. The bottom dead center stop operation is a movement in which the slide 3 stops at the bottom dead center 72 of the crankshaft 5 for a predetermined period of time and then rotates forward.

[0124] The strip region 310 is a strip-shaped image 214 , with two ends 313 , 314 located far apart from each other. The image 214 extends downward from one end 313 of the two ends 313 , 314 and turns upward at the lower end 32 to reach the other end 314 .

[0125] The ends 313 and 314 correspond to the ascending limit 11 of the slider 3, and the lower end 32 corresponds to the descending limit 12 of the slider 3. The lower end 32 has at least one third slider operation area 413 extending horizontally. By using the image 214 of the band-shaped area 310, the operator can set the movement while visually recognizing that the slider 3 is temporarily stopped at the bottom dead center 72.

[0126] The strip 310 is generally U-shaped, with its upper ends 31 being spaced apart and separated by two ends 313 and 314. Within the strip 310, the first slider action area 411, the second slider action area 412, the third slider action area 413, the fourth slider action area 414, and the fifth slider action area 415 extend continuously from the upper right side along the extension direction of the strip 310.

[0127] like Figure 18 As shown, each slider action area (411-415) and Figure 4 Similarly to the example of , the speed of the slider 3 can be set by changing the maximum amplitude W. Here, the target speed of the slider 3 in the second slider operation area 412 is set to 50%. Furthermore, the operator can slide (slide) the finger 80 from the outside to the inside while contacting the third slider operation area 413, or move (contract) the finger to narrow the third slider operation area 413, thereby making the bottom dead center 72 ( Figure 1 ) The stop time of the upper slider 3 changes (0.0 sec → 6.0 sec). When the operation button 26e is touched (clicked), the calculation cycle SPM is "8 min -1 ” is displayed by the display unit 22.

[0128] like Figure 19 Shown, indicating Figure 17 The forward rotation curve 76a of the initial state of the movement of the middle slider 3 is as follows Figure 18 The movement of the slider 3 shown in the action curve 76b is changed to a bottom dead center stop.

[0129] The operator of the press machine 1 can easily set the movement of the slide 3 while visually recognizing the stagnant state of the bottom dead center 72 through the strip-shaped area 310 .

[0130] 5. Two-hit action

[0131] use Figure 20 and Figure 21The operation of setting the movement of the slider 3 for the two-stroke action will be described. Figure 20 224 and 225 of the display unit 22 of the press machine 1 showing two striking motions. Figure 21 This diagram shows the movement of the slide 3 during the two-stroke operation of the press 1. In this movement, even if springback of the workpiece occurs after the forming process associated with the first downward movement of the slide 3, this springback is reduced by the forming process associated with the second downward movement of the slide 3 (forming within the same mold).

[0132] like Figure 20 As shown, when the operator touches (clicks) the double-stroke motion selection button 26g with his finger 80, the double-stroke motion is selected, and the display unit 22 displays images 224 and 225. The double-stroke motion is a motion in which the slide 3 is lowered twice to the lowering limit 12 (bottom dead center 72) in one cycle to perform a punching process.

[0133] The strip area 320 is composed of two adjacent strip-shaped images 224 and 225. The images 224 and 225 are respectively connected to the upper limit 11 ( Figure 1 ) corresponds to the other end 324, 326 and the slider 3 passing the lower limit 12 ( Figure 1 )The reversal point of the rising position 13( Figure 21 ) corresponds. The two strip-shaped images 224 and 225 are combined so that the other ends 324 and 326 are adjacent to each other. By using the images 224 and 225 of the strip-shaped area 320, the operator can set the slider 3 while visually recognizing the movement of the so-called double hit.

[0134] The strip area 320 has a shape that is a left-right inversion of one of the two adjacent J-shaped images 224 and 225. The initial downward movement of the slider 3 is set in the first slider movement area 421 and the second slider movement area 422 starting from one end 323 of the upper right image 224, and the upward movement of the slider 3 is set from the corresponding downward limit 12. Figure 20 The second downward movement is set in the fourth slider action area 424 starting from the end 326 of the left image 225, and the second upward movement of the slider 3 is set at the corresponding position of the downward limit 12. Figure 20 The left lower end 32 extends to the fifth slider action area 425 and one end 325 of the sixth slider action area 426 .

[0135] Each slider action area (421-426) can be divided by the split button 26c and can be combined by the combine button 26d. Figure 6 and Figure 7 Make changes as described.

[0136] exist Figure 20 , the state in which the operator uses the finger 80 to shrink and change the width of the second slider operation area 422 and the fourth slider operation area 424 from the initial state (the state in which all the slider operation areas (421 to 426) are at the maximum speed (100%)) is shown.

[0137] like Figure 21 As shown, Figure 20 The motion of the slide block 3 provided in the figure can be expressed as two striking action curves 77. The slide block 3 descends from the top dead center 70 and rises at the bottom dead center 72, descends again at the reversal point 13 and rises again at the bottom dead center 72.

[0138] In order to allow the operator to confirm the change in the settings of the band-shaped areas 30, 300, 310, 320, the display unit 22 also displays the Figure 9 、 Figure 10 、 Figure 16 、 Figure 19 and Figure 21 motion curve diagram.

[0139] The operator of the press machine 1 can easily set the movement of the slide 3 while visually confirming the two striking actions through the band-shaped area 320 .

[0140] 6. Choice of exercise

[0141] Figure 2 The press machine 1 shown in the figure stores the shapes of a plurality of band-shaped areas 30, 300, 310, and 320 in the storage unit 64. The display unit 22 selects any one of the plurality of band-shaped areas 30, 300, 310, and 320 from the storage unit according to the input operation to the operation unit 60 and displays it. The input operation to the operation unit 60 may also be, for example, by long pressing Figures 4 to 7 The pendulum motion selection button 26b is shown to display the bottom dead center stop motion selection button 26f on the display unit 22, or to press the pendulum motion selection button 26g twice. By pre-setting a plurality of band-shaped areas 30, 300, 310, and 320 in the storage unit 64, the operating panel 20 can flexibly accommodate various motion settings.

[0142] The types of the band-shaped regions 30 , 300 , 310 , and 320 stored in the storage unit 64 are not limited to those described in the above embodiment, and may be prepared in accordance with other sports.

[0143] 7. How to set up the press

[0144] For use Figures 1 to 21 The installation method of the press machine 1 will be described.

[0145] A method according to an embodiment of the present invention is a method for setting up the press machine 1 using the operation panel 20 of the press machine 1.

By moving the boundaries (51, 52, 53, etc.) of the slider motion areas (41, 42, 43, 44, 45, 46, etc.) for which the speed of the slider 3 is set, the height range of the slider 3 corresponding to the slider motion area (41, 42, 43, 44, 45, 46, etc.) can be set. Therefore, the operator can set the movement of the slider 3 while visually recognizing the movement of the slider 3 after the setting.
