[0006] Technical Problem to be Solved by the Invention

[0007] Here, in recent years, there has been a demand for energy saving of equipment due to the global warming effect. In the forming apparatus described in the above technology, not only stamping is performed, but also forming processes such as heating the metal material and supplying a fluid to the heated metal material are added. Therefore, in a forming system accompanied by heating or a forming system accompanied by fluid supply, the energy consumption becomes large, and thus energy saving needs to be achieved. And, as a prerequisite for this, it has become very important for the equipment owner who introduces such equipment to understand the energy consumption of the equipment under the trend of Sustainable Development Goals (SDGs).

[0008] The present invention has been completed to solve such problems, and an object thereof is to provide a display device capable of achieving energy saving of a forming system.

[0009] Means for Solving the Technical Problem

[0010] The present invention relates to a display device used in a forming system that heats and / or expands a metal material and moves a die to form the metal material, and at least displays the energy consumption corresponding to each part accompanying the forming of the metal material.

[0011] The display device is a display device in a forming system that performs at least one of heating and expanding a metal material and moves a die to form the metal material. In contrast, the display device at least displays the energy consumption corresponding to each part accompanying the forming of the metal material. Therefore, by visually confirming this energy consumption, an operator can modify the used device or improve the usage method to achieve energy saving. Thus, energy saving of the forming system can be achieved.

[0012] It may be as follows, that is, the forming system has multiple energy-consuming devices, and the display device displays the energy consumption of each device by distinguishing the states of the multiple devices. At this time, the operator can easily visually identify the energy consumption of each device classified into a specified type.

[0013] For example, it may be as follows, that is, the multiple devices at least include an electric heating device, a high-pressure gas generating device, a bending device, and a cutting device.

[0014] It may be as follows, that is, the forming system has multiple energy-consuming devices, and each of the devices has its constituent components, and the display device can adjust and display the hierarchy of the constituent components of the device. At this time, according to the hierarchy that the operator wishes to confirm, the situation of the energy consumption in the forming system can be visually identified.

[0015] It may be as follows, that is, the forming system has multiple energy-consuming devices, and the display device can display the cumulative energy consumption of each device. At this time, by visually confirming the past actual energy consumption, the current situation of the device can be judged.

[0016] It may be as follows, that is, the display device displays the energy consumption of the metal material in the forming of each part. At this time, the operator can directly confirm the energy consumption accompanying the forming of each part.

[0017] It may be as follows, that is, the display device displays the cumulative energy consumption of the metal material in the process of part forming. At this time, the operator can confirm the past actual energy consumption.

[0018] It may be as follows, that is, the display device displays the energy consumption of the metal material at regular time intervals during part forming. At this time, by confirming the energy consumption within the specified time interval, the operator can confirm the energy consumption accompanying the forming of each part with the metal material.

[0019] It may be as follows, that is, the display device displays the cumulative energy consumption accompanying the metal material in the process of part forming at regular time intervals. At this time, by confirming the cumulative energy consumption within the specified time interval, the operator can confirm the past actual energy consumption accompanying the forming of each part with the metal material.

[0020] The forming system is a forming system equipped with the above display device.

[0021] This forming system has an effect with the same purpose as the display device.

[0033] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In addition, in each drawing, the same parts or corresponding parts are denoted by the same reference numerals, and redundant description is omitted.

[0034] Figure 1 is a schematic structural diagram showing the structure of the forming system 100 according to the present embodiment. The forming system 100 is a system for forming a metal material. As Figure 1 shown, the forming system 100 includes a forming device 10, a bending device 101, a feed-side transfer robot 102, a discharge-side transfer robot 103, a laser cutting device 104 (cutting device), and a display device 105. In the present embodiment, as the metal material, a metal tube material 5 is used.

[0035] The forming device 10 is a device for processing the heated metal tube material 5. In the present embodiment, the forming device 10 performs stamping on the heated metal tube material 5. In the present embodiment, as the forming device 10, a forming device is adopted which forms and quenches a metal tube with a hollow shape by supplying a fluid to the heated metal tube material 5 to bring it into contact with the forming surface of the forming die. The forming device 10 includes a stamping device 50, an electric heating device 51, a high-pressure gas generating device 52, and a cooling water cooler 53.

[0036] Figure 2 is a schematic diagram showing the structure of the forming device 10. As Figure 2 shown, in the present embodiment, the forming device 10 is provided on a horizontal plane. The forming device 10 includes a forming die 11, a holding portion 12, a fluid supply portion 13, a heating portion 14, and a cooling portion 15. In addition, in this specification, the metal tube material 5 refers to a hollow object before forming in the forming device 10. The metal tube material 5 is a tube material made of a quenchable steel type. When the metal tube material 5 is set in the forming device 10, the direction in which the reference axis of the metal tube material 5 extends is sometimes referred to as the "axial direction D1". And in the horizontal direction, the direction orthogonal to the axial direction D1 is sometimes referred to as the "width direction D2".

[0037] The forming die 11 is a die for forming a metal tube from the metal tube material 5, and includes a lower die 16 and an upper die 17 that face each other in the vertical direction. The lower die 16 and the upper die 17 are made of steel blocks. Recesses for accommodating the metal tube material 5 are provided in the lower die 16 and the upper die 17 respectively. When the lower die 16 and the upper die 17 are in a state of being in close contact with each other (closed die state), a space for forming the target shape of the metal tube material 5 to be formed in each recess is formed. Therefore, the surface of each recess becomes the forming surface of the forming die 11. The lower die 16 is fixed to the base 18 via a die holder or the like. The upper die 17 is fixed to the slider of the drive mechanism via a die holder or the like. In addition, the drive mechanism is a mechanism that moves at least one of the lower die 16 and the upper die 17. The stamping device 50 is composed of the forming die 11, the drive mechanism of the forming die 11, and the surrounding base 18, frame, etc.

[0038] The holding part 12 is a mechanism for holding the metal tube material 5 disposed between the lower die 16 and the upper die 17. The holding part 12 includes a holding member 21A that holds the metal tube material 5 at one end side in the axial direction D1 of the forming die 11 and a holding member 21B that holds the metal tube material 5 at the other end side in the axial direction D1 of the forming die 11. The holding members 21A and 21B on both sides in the axial direction D1 are divided into upper and lower members, and hold the metal tube material 5 by clamping the vicinity of the end of the metal tube material 5 in the vertical direction. A drive mechanism (not shown) is provided in the holding members 21A and 21B, and can move in the vertical direction. In addition, the holding members may not be divided into upper and lower sides, and may be divided into left and right sides, for example.

[0039] The fluid supply part 13 is a mechanism for supplying high-pressure fluid into the metal tube material 5 held between the lower die 16 and the upper die 17. The fluid supply part 13 supplies high-pressure fluid to the metal tube material 5 in a high-temperature state to expand the metal tube material 5. The fluid supply part 13 is provided at both end sides in the axial direction D1 of the forming die 11. The fluid supply part 13 includes: nozzles 22A and 22B that supply fluid into the metal tube material 5 from the opening parts at the ends of the metal tube material 5; and drive mechanisms 23A and 23B that move the nozzles 22A and 22B forward and backward with respect to the opening parts of the metal tube material 5. In addition, the fluid supply part 13 may supply a gas such as high-pressure air or inert gas as the fluid. The fluid supply part 13 has a high-pressure gas generating device 52 for supplying high-pressure fluid to the nozzles 22A and 22B. The high-pressure gas generating device 52 supplies high-pressure fluid to the nozzles 22A and 22B. And the fluid supply part 13 may be set as the same device together with the holding part 12 having a mechanism for moving the metal tube material 5 in the vertical direction.

[0040] The heating part 14 is a device for heating the metal tube material 5. The heating part 14 heats the metal tube material 5 by energizing the metal tube material 5. The heating part 14 uses the holding members 21A and 21B as electrodes. The heating part 14 allows current to flow from the power source 56 through the holding members 21A and 21B as electrodes to the metal tube material 5 in a state where the metal tube material 5 is held by the holding members 21A and 21B used as electrodes. The heating part 14 constitutes an electric heating device 51.

[0041] The cooling part 15 is a mechanism for cooling the forming die 11. The cooling part 15 includes a cooling water cooler 53 that supplies cooling water to the dies 16 and 17. The cooling part 15 has flow paths formed inside the dies 16 and 17. The cooling part 15 cools the dies 16 and 17 by causing the cooling water to flow through the flow paths.

[0042] As Figure 1As shown, the bending device 101 is a device for bending the metal tube material 5 in the pre-processing stage of the forming device 10. For example, in the case where the forming device 10 has a forming die 11 for stamping the metal tube material 5 in a bent state, the bending device 101 bends the metal tube material 5 provided before the forming device 10. The feeding-side transfer robot 102 is a device for transferring the metal tube material 5 bent by the bending device 101 from the bending device 101 to the forming device 10. The discharging-side transfer robot 103 is a device for transferring the formed metal tube from the forming device 10 to the laser cutting device 104. The laser cutting device 104 is a device for cutting a desired part of the formed metal tube using a laser.

[0043] The display device 105 is a device for displaying various information in the form of an image. In a forming system that performs at least one of heating and expanding the metal tube material 5 and moves the die to form the metal tube material 5, the display device 105 displays at least the energy consumption associated with the forming of the metal tube material 5 corresponding to each part. Among the multiple metal tube materials 5 formed by the forming system 100, a single metal tube material 5 corresponds to the metal tube material 5 related to one part. In addition, displaying the energy consumption associated with the forming of the metal tube material 5 corresponding to each part includes not only directly displaying the energy consumption associated with the forming of the metal tube material 5 related to one part, but also indirectly displaying it in a form after data processing of the energy consumption associated with the forming of the metal tube material 5 for each part. The display device 105 can visualize the energy consumption associated with the hot forming of the metal tube material 5. The display device 105 can visualize the energy consumption of at least the devices used for hot forming in the forming system 100. And, the display device 105 can visualize the energy consumption associated with forming the metal tube material 5 using a fluid. The display device 105 can visualize the energy consumption of at least the devices used for forming using a fluid in the forming system 100. In addition, of course, each part includes one part, multiple parts, one batch (the number of batches can be determined arbitrarily), etc.

[0044] Specifically, the display device 105 displays an image GF1 as shown in Figure 3 . The image GF1 shows the schematic power supply lines LX and windows W1, W2A, W2B corresponding to the respective devices in the forming system 100.

[0045] The power supply line LX includes a supply source line L1, a main line L2, and branch lines L3. The supply source line L1 is a line extending from the power supply source of the forming system 100. The main line L2 is a line for distributing the power supplied from the supply source line L1 to the respective branch lines L3. The branch lines L3 are lines branching from the main line L2 to the respective devices.

[0046] Window W1 is a window that displays the content of each device in the forming system 100. Window W1 is displayed as being connected to a branch line L3 extending from the main line L2. In the present embodiment, device names such as "bending device", "feeding-side handling robot", "discharging-side handling robot", and "laser cutting device" are displayed in each window W1, and device names such as "stamping device", "electrical heating device", "high-pressure gas generating device", and "cooling water cooler" of the forming device 10 are also described.

[0047] Windows W2A and W2B are windows that display the energy consumption consumed through each line. In the present embodiment, the energy consumption is displayed in terms of electric energy, i.e., "kWh". Window W2A is arranged beside the supply source line L1. Window W2A displays the energy consumption consumed by the entire forming system 100. Window W2B is arranged beside each branch line L3. Window W2B displays the energy consumption consumed by each device. In addition, in windows W2A and W2B, the values of measuring instruments provided at corresponding positions in the forming system 100 can be displayed, or calculated values calculated based on the values of other measuring instruments can be displayed. In windows W2A and W2B, values that change in real time can be displayed, or operation values such as the average value over a specified period can be displayed.

[0048] In addition, when the display device 105 visualizes the energy consumption associated with the hot forming of the metal tube material 5, it is sufficient to display at least the energy consumption of the "electrical heating device", and the display of the energy consumption of other devices can be omitted. When the display device 105 visualizes the energy consumption associated with the forming of the metal tube material 5 using a fluid, it is sufficient to display at least the energy consumption of the "high-pressure gas generating device", and the display of the energy consumption of other devices can be omitted. This is because the present forming device 10 is equivalent to a device in which the heating step and the gas supply step in the forming device 10 easily consume energy, and different from other forming devices, it is necessary to detect aging or abnormalities.

[0049] Moreover, the display device 105 can display each energy consumption separately while distinguishing the states of multiple devices in the forming system 100. For example, the display device 105 can display the energy consumption of each device separately while distinguishing the states of multiple devices using voltage. Alternatively, the display device 105 can display the energy consumption of each device separately while distinguishing the states of multiple devices by type.

[0050] As Figure 4As shown in (a), the supply source line L1 branches into a main line L2A of 440V and a main line L2B of 220V. Windows W1 and W2B of the devices operating at 440V are shown on the 440V main line L2A side. Windows W1 and W2B of the devices operating at 220V are shown on the 220V main line L2B side. Thus, the energy consumption of the devices operating at 440V and the energy consumption of the devices operating at 220V can be respectively displayed. And, as Figure 4 shown in (b), the electric heating device can be displayed in a branching manner different from other devices on the supply source line L1. At this time, the electric heating device and other devices can be respectively displayed. In this way, the energy consumption can be displayed according to the preferences of the equipment owner or operator.

[0051] And, the shaping system 100 has a plurality of energy-consuming devices, and each device has its constituent components. The display device 105 can adjust and display the hierarchy of the constituent components of the device. For example, the electric heating device 51 has four energizing parts, namely, an upper holding part 21A and a lower holding part 21A, and an upper holding part 21B and a lower holding part 21B, as its constituent components. Therefore, the display device 105 can, as Figure 3 shown, only display the energy consumption at the overall hierarchy level of the electric heating device 51, or, as Figure 5 shown, display the energy consumption at the hierarchy level of each energizing part.

[0052] Specifically, as Figure 5 shown in (a), the window W1A of the "electric heating device" and the window W2B of the energy consumption can be displayed at the hierarchy level of the branch line L3 branched from the main line L2, and the window W1B of the "energizing parts 1 - 4" and the window W2C of the energy consumption can be displayed at the hierarchy level of the branch line L4 further branched from the branch line L3. Or, as Figure 5 shown in (b), the display of the "electric heating device" can be omitted, and directly the window W1B of the "energizing parts 1 - 4" and the window W2C of the energy consumption at the hierarchy level of the branch line L4 branched from the main line L2 can be displayed. In this way, by displaying the energy consumption in a state where the lower layer hierarchy is refined, for example, abnormalities in the energizing parts can also be detected in advance.

[0053] And, the display device 105 can display the cumulative energy consumption of each device. As Figure 6As shown, the display device 105 displays an image GF2 that shows the cumulative energy consumption of each device in chronological order. In column A1 at the left end of the table in the image GF2, the names of the devices of the forming system 100 are recorded. In column A2 at the upper end of the table of the image GF2, the date and time of recording are recorded. If the "Current Value Record" button is clicked, the display device 105 records the current date and time and the cumulative power values of each device and displays them in the leftmost column. The leftmost column in the table is the latest data. The farther to the right, the earlier the date and time. The recording can be performed up to a predetermined number (for example, 10 items). If the predetermined number is exceeded, the earliest record is deleted.

[0054] The display device 105 can, for example, display information as Figure 9 shown. On the left side of the Figure 9 screen, each part of the metal tube material 5 is identified by "Product Number". As Figure 9 shown in the upper left chart, the display device 105 displays the energy consumption associated with the forming of each part. The horizontal axis of this chart is the product number (identification of the part) of the metal tube material 5, and the vertical axis is the power consumption (energy consumption) associated with the forming of the corresponding product number. As Figure 9 shown in the lower left chart, the display device 105 displays the cumulative energy consumption associated with the part forming process. The horizontal axis of this chart is the product number (identification of the part) of the metal tube material 5, and the vertical axis is the cumulative value of the power consumption (energy consumption) associated with the forming of the corresponding product number and the power consumption (energy consumption) associated with the forming up to now.

[0055] As Figure 9 shown in the upper right chart, the display device 105 displays the energy consumption during the forming of the part at a specified time interval. Here, a chart is shown at an interval of one hour. The horizontal axis of this chart is the time, and the vertical axis is the power consumption (energy consumption) used during the period of the time interval from each time. When the metal tube material 5 related to multiple parts is formed during the time interval, the total power consumption associated with the forming of this number of metal tube materials 5 is displayed. As Figure 9 shown in the lower right chart, the display device 105 displays the cumulative energy consumption associated with the part forming process at a specified time interval. Here, a chart is shown at an interval of one hour. The horizontal axis of this chart is the time, and the vertical axis is the cumulative value of the power consumption (energy consumption) used during the period of the time interval from each time and the power consumption (energy consumption) associated with the forming up to now.

[0056] In addition, the display device 105 can display the energy consumption (cumulative energy consumption) of the product numbers and times in the range selected by the operator. For example, in Figure 9On the left side, a chart with product numbers "1 to 20" is shown, but it is also possible to select a part of the range and display the energy consumption of the selected product numbers.

[0057] Next, the effects of the display device 105 according to this embodiment will be described.

[0058] The display device 105 is the display device 105 in the forming system 100 that heats and / or expands the metal tube material 5 (metal material) and moves the mold to form the metal tube material 5. In contrast, the display device 105 at least displays the energy consumption associated with the forming of each part of the metal tube material 5. Therefore, by visually confirming this energy consumption, the operator can modify the devices used or improve the usage method to achieve energy savings. Thus, energy savings of the forming system can be achieved.

[0059] The display device according to this embodiment is the display device 105 in the forming system 100 that forms the metal tube material 5 by heating the metal tube material 5 (metal material), and visualizes the energy consumption associated with the hot forming of the metal tube material 5.

[0060] The display device 105 is the display device in the forming system 100 that forms the metal tube material 5 by heating the metal tube material 5. In contrast, the display device 105 visualizes the energy consumption associated with the hot forming of the metal tube material 5. Therefore, by visually confirming this energy consumption, the operator can grasp the energy consumption of the actual equipment. And the devices used can be modified or the usage method can be improved to achieve energy savings. Thus, energy savings of the forming system 100 can be achieved.

[0061] The display device 105 according to this embodiment is the display device in the forming system 100 that forms the metal tube material 5 by supplying fluid to the metal tube material 5, and visualizes the energy consumption associated with forming the metal tube material 5 using the fluid.

[0062] The display device 105 is the display device in the forming system 100 that forms the metal tube material 5 by supplying fluid to the metal tube material 5. In contrast, the display device 105 can visualize the energy consumption associated with forming the metal tube material 5 using the fluid. Therefore, by visually confirming this energy consumption, the operator can grasp the energy consumption of the actual equipment. And the devices used can be modified or the usage method can be improved to achieve energy savings. Thus, energy savings of the forming system 100 can be achieved.

[0063] It may be as follows, that is, the forming system 100 has a plurality of energy-consuming devices, and the display device 105 displays the energy consumption of each device by differentiating the states of the plurality of devices. At this time, the operator can easily visually recognize the energy consumption of each device classified into a specified type.

[0064] For example, it may be as follows, that is, the plurality of devices at least include an electric heating device, a high-pressure gas generating device, a bending device, and a cutting device.

[0065] It may be as follows, that is, the forming system 100 has a plurality of energy-consuming devices, the devices have their constituent components, and the display device 105 can adjust and display the hierarchy of the constituent components of the devices. At this time, the operator can visually recognize the status of the energy consumption in the forming system 100 according to the hierarchy to be confirmed.

[0066] It may be as follows, that is, the forming system 100 has a plurality of energy-consuming devices, and the display device 105 can display the cumulative energy consumption of each device. At this time, by visually confirming the past actual energy consumption, the status of the current device can be judged.

[0067] It may be as follows, that is, the display device 105 displays the energy consumption generated during the forming of each part of the metal tube material 5. At this time, the operator can directly confirm the energy consumption accompanying the forming of each part.

[0068] It may be as follows, that is, the display device 105 displays the cumulative energy consumption of the metal tube material 5 during the part forming process. At this time, the operator can confirm the past actual energy consumption.

[0069] It may be as follows, that is, the display device 105 displays the energy consumption of the metal tube material 5 during the part forming at a specified time interval. At this time, by confirming the energy consumption within the specified time interval, the operator can confirm the energy consumption accompanying the forming of the metal tube material 5 corresponding to each part.

[0070] It may be as follows, that is, the display device 105 displays the cumulative energy consumption of the metal tube material 5 during the part forming process at a specified time interval. At this time, by confirming the cumulative energy consumption within the specified time interval, the operator can confirm the past actual value of the energy consumption accompanying the forming of the metal tube material 5 for each part.

[0071] The forming system 100 is a forming system equipped with the above-mentioned display device 105.

[0072] This forming system 100 has an effect similar to that of the display device 105.

[0073] The present invention is not limited to the above embodiments.

[0074] In the above-described embodiment, the display device 105 related to the forming system 100 having the forming device 10 as shown in Figure 2 is illustrated. Alternatively, the display device 105 may also display the forming system 100 having a forming device (for example, a forming device for hot stamping) that performs heating without fluid supply. The forming device for hot stamping does not perform electric heating but performs furnace heating, and does not perform hydroforming using fluid. Therefore, the metal material may not be a metal tube material but may be a metal sheet or the like. At this time, the display device 105 may display an image GF3 as shown in Figure 7 . As shown in Figure 7 , device names such as "heating furnace", "loading side handling robot", "unloading side handling robot", and "laser cutting device" are displayed in the window W1, and device names such as "stamping device" and "cooling water cooler" of the forming device 10 are also described. In addition, the power consumption of the heating furnace is displayed in Figure 7 , but the CO 2 emission amount consumed by the heating furnace may also be displayed. At this time, for the stamping device or the handling robot, the power consumption can be converted into the CO 2 emission amount and displayed.

[0075] The display device 105 may display the forming system 100 having a forming device (for example, a forming device for hydroforming) that performs fluid supply without heating. The forming device for hydroforming does not perform heating. At this time, the display device 105 may display an image GF4 as shown in Figure 8 . As shown in Figure 8 , device names such as "loading side handling robot", "unloading side handling robot", and "laser cutting device" are displayed in the window W1, and device names such as "stamping device" and "high-pressure pump" of the forming device 10 are also described.

[0076] Moreover, a manufacturing number or a QR code (registered trademark) may be engraved on the metal material, and the energy consumption amount associated with the forming of each part (single-piece metal material) on the metal material may be displayed on the display device. And, the processes required for producing the metal material (molten iron melting process, tube manufacturing process for processing a metal plate into a tube, preforming process for preforming the tube (including bending process, etc.)) may be additionally displayed on the display device.

[0077] Moreover, the energy consumption amount consumed in the material processing processes (cutting process, trimming process) after the metal material is formed may be displayed on the display device.

[0078] The unit of the energy consumption amount may be displayed in terms of electric power or may be displayed in terms of the CO 2 emission amount. Moreover, the CO2 Both emissions and electricity, or switch to one of them.

[0079] In this way, it is possible to immediately grasp the energy consumption of each metal material forming based on the manufacturing number or QR code, etc., which can contribute to the grasp of energy consumption or the improvement of equipment, etc.

[0080] The forming device according to this embodiment describes a device that heats, expands, stamping, cools, etc. without moving the metal tube material within the mold, but it can also be applied to other forming devices. For example, it is self-evident that the present application can also be applied to a forming device that moves the metal tube material and heating table, expansion table, stamping table, cooling table, etc. within the forming device for forming. That is, the specific structure of the forming device applying the present application is not limited within the scope not departing from the gist of the present application, and can also be widely applied to devices with changes in each component of the forming device.
