An embodiment of the present invention will be described below.
Although the wording "information" is used in this specification, the wording "information" can be rephrased as "data" and the wording "data" can be rephrased as "information."

FIG. 1 is a diagram for explaining an example of a press apparatus 1. As shown in FIG.

The press device 1 includes an upper mold device 10 and a lower mold device 20. A mold 30 is disposed in each of the upper mold device 10 and the lower mold device 20. The mold 30 is used to press a workpiece (work 100). The mold 30 has a mold that follows the shape of the workpiece 100 to be manufactured by press working. In the press device 1, when a workpiece 100 is placed in a mold 30 and at least one of the upper mold device 10 and the lower mold device 20 is operated, the workpiece 100 is pressed.

In a conventional press device, when at least one of the upper mold device and the lower mold device is operated, impact noise is generated due to collision of metal parts during press processing. In the press apparatus 1 of this embodiment, a weight 40 (see FIG. 2(A)) is disposed on the mold 30 in order to suppress such impact noise.

That is, the weight 40 has at least one of a weight and a shape depending on the natural frequency of the mold 30, and is disposed on the mold 30. That is, the weight 40 may have at least one of a shape and weight that attenuates the sound generated based on the natural frequency of the mold 30 when pressing the workpiece (work 100).

FIG. 2 is a diagram for explaining an example of the sound generated in the press device 1. As shown in FIG. FIG. 2(A) is a diagram (schematic diagram) for explaining an example of the mold 30 and the weight 40, and FIG. 2(B) is a graph regarding sound frequency (horizontal axis) and sound-related amplitude (vertical axis). FIG. 2(C) is a graph relating to the frequency of sound (horizontal axis) and the amplitude (vertical axis) of the sound, and is a diagram explaining the case where the amplitude is lowered.

Attenuating the sound may include at least one of relatively lowering the frequency of the generated sound and relatively lowering the level of the generated sound.

Workers often find sounds with relatively high frequencies unpleasant. Therefore, if the generated sound has a peak, the weight 40 (see FIG. 2(A)) placed on the mold 30 can be adjusted to adjust the frequency of the peak (frequency band near the peak). so that the peak band)) is relatively lower. In other words, by placing the weight 40 on the mold 30, the change can be made from the case shown by the solid line in FIG. 2(B) (when there is no weight 40) to the case shown by the broken line in FIG. 2(B) (when the weight 40 is present). I will make it happen. As a specific example, if the frequency of the generated sound (for example, the peak of the sound or the peak band of the sound) is relatively high, the frequency of the sound is lowered by about 2000 Hz. Or, as a specific example, if the frequency of the generated sound (for example, the peak of the sound or the peak band of the sound) is relatively high, the frequency of the sound (for example, the peak of the sound or the peak band of the sound) is 500 Hz. The frequency range should be 1000 Hz or more.

Further, when the sound level (volume) is relatively high, workers often find the sound unpleasant. For this reason, the weight 40 (see FIG. 2(A)) placed on the mold 30 is adjusted so that the level of the generated sound is relatively reduced (see FIG. 2(C)). That is, by placing the weight 40 in the mold 30, the case shown by the solid line in FIG. 2(C) (when there is no weight 40) is changed from the case shown by the broken line in FIG. 2(C) (when the weight 40 is present). I will make it happen.

There may be multiple types of weights 40 (for example, multiple types of weights 40 with different weights and shapes). At least one weight 40 may be selected depending on the frequency and level (volume) of the generated sound.
As a specific example, if the frequency of the generated sound is to be relatively lowered, a relatively heavy (or relatively light) weight 40 may be selected. As an example, when changing the frequency of sound, by making the weight 40 heavier (or lighter) (by increasing the amount of change in weight relatively), the change in frequency can be made relatively larger. It becomes possible to do so.

Alternatively, as a specific example, if the frequency of the generated sound is to be relatively lowered, the weight 40 having a shape with a large (or small) contact area with the mold 30 may be selected. As an example, when changing the frequency of sound, the frequency can be changed by increasing (or decreasing) the contact area between the mold 30 and the weight 40 (by relatively increasing the amount of change in the contact area). It becomes possible to make the change relatively large.

Similarly, as a specific example, if the level (volume) of the generated sound is to be relatively lowered, a relatively heavy (or relatively light) weight 40 may be selected. As an example, when changing the sound level, by making the weight 40 heavier (or lighter) (by increasing the amount of change in weight relatively), the change in the sound level can be relatively controlled. It becomes possible to increase the size to

Alternatively, as a specific example, if the level (volume) of the generated sound is to be relatively lowered, the weight 40 having a shape with a large (or small) contact area with the mold 30 may be selected. good. For example, when changing the sound level, by making the contact area between the mold 30 and the weight 40 larger (or smaller) (by making the amount of change in the contact area relatively larger), the sound level can be changed. It becomes possible to make the change in the level relatively large.

Note that the weight 40 is not limited to the example in which the shape and weight are determined by the above method, and various shapes and various weights may be determined by various methods.

When adjusting the weight 40, for example, shim adjustment may be performed. That is, the weight 40 may include a shim used for shim adjustment. Weight 40 can be adjusted by adding or subtracting one or more shims.

FIG. 3 is a diagram for explaining an example of placing the weight 40 on the mold 30.

First, as an example shown in FIG. 3(A), a cushioning member such as rubber 50 is attached to the side of the weight 40 that contacts the mold 30. In this case, the rubber 50 may be attached to the weight 40 using a member such as a bolt 60. The thickness of the rubber 50 is adjusted as appropriate.

Next, as an example shown in FIG. 3(B), a weight 40 is attached to the mold 30. The weight 40 is attached to the mold 30 so that the surface on which the rubber 50 is arranged is in contact with the mold 30. Even in this case, the weight 40 may be attached to the mold 30 using members such as bolts 60.

Thereby, the weight 40 is attached to the mold 30, as shown in an example in FIG. 3(C). Note that the size, quantity, etc. of the members such as the bolts 60 mentioned above are appropriately set according to the size of the weight 40, etc.

Furthermore, one or more weights 40 may be disposed on the mold 30. As an example, one or more weights 40 may be placed relatively close to the source of the sound. When a plurality of weights 40 are arranged in the mold 30, the weights of the plurality of weights 40 may be the same or different. In this case, as an example, a weight 40 is disposed on the mold 30 at a position relatively close to the sound source, and a relatively light weight 40 is disposed at a position relatively far from the sound source. 40 may be arranged.

The weight and shape of the weight 40 described above may be determined, for example, by conducting an experiment or the like. Alternatively, the weight 40 described above may be determined by, for example, performing a predetermined process in the information processing device 200, which will be described later.

As an example, if the weight of the mold 30 is approximately 10 tons, the weight 40 may be within about 10% (approximately 1 ton) of the weight of the mold 30. In this case, when a plurality of weights 40 are arranged in the mold 30, the total weight of the plurality of weights 40 may be within 1 ton, and the weight of each of the plurality of weights 40 may be within 1 ton. You can.

In this way, the press device 1 suppresses vibrations and reduces noise by attaching to the mold 30 a stabilizer (weight 40) that corresponds to the natural frequency of the mold 30. It is possible to move out of the range. The weight 40, which serves as a stabilizer, is of a shim adjustable type, and can be finely adjusted by modifying the mold 30 during preparation for production.

Next, the information processing device 200 will be explained.
The information processing device 200 is a device used when pressing a workpiece (work 100) using a mold 30. The information processing device 200 may be, for example, a computer (server, desktop, laptop, etc.).

FIG. 4 is a block diagram for explaining the information processing device 200 according to one embodiment.

The information processing device 200 includes a measurement section 221, a communication section 222, a storage section 223, a display section 224, an acquisition section 211, a calculation section 212, a determination section 213, and an output control section 214. The acquisition unit 211, the calculation unit 212, the determination unit 213, and the output control unit 214 may be realized as a function of the control unit 210 (for example, an arithmetic processing device) of the information processing device 200. The communication unit 222, the storage unit 223, and the display unit 224 may be an embodiment of the “output unit” of the information processing device 200.

The measurement unit 221 measures a physical quantity related to the impact generated on the mold 30 when press working is performed. The measurement unit 221 may measure, for example, a physical quantity related to sound as the physical quantity. That is, the measuring unit 221 measures, for example, the frequency of the sound generated when pressing is performed and the level (volume) of the sound generated when pressing is performed, as physical quantities (physical quantities related to sound). You can. When measuring a physical quantity, the measuring unit 221 outputs information regarding the measured physical quantity to the control unit 210.

Specifically, the measurement unit 221 measures the sound generated by the mold 30. The measurement unit 221 includes, for example, a microphone and an analysis unit (not shown). For example, the microphone may be placed relatively close to the press device 1 and may collect sounds generated during press processing. The analysis unit analyzes, for example, sound collected by a microphone. For example, the analysis unit performs at least one of analyzing the frequency of the sound collected by the microphone and the level (volume) of the sound collected by the microphone. The sound frequency analysis and the sound level analysis can be performed using, for example, various known techniques.
Note that the measuring unit 221 may measure the physical quantity in a state where the weight 40 is not placed on the mold 30, for example.

The communication unit 222 is capable of communicating with, for example, a device (external device) (not shown) outside the information processing device 200. The external device may be, for example, an external server and an external terminal (eg, a desktop, laptop, tablet, smartphone, etc.). For example, the communication unit 222 may transmit information regarding the weight 40 determined by the determination unit 213 (described later) to the external device based on the control of the output control unit 214 (described later).

The storage unit 223 stores, for example, various information and programs. The storage unit 223 may store information regarding the weight 40 determined by the determination unit 213 based on the control of the output control unit 214, for example.

The display unit 224 displays, for example, characters, symbols, images, and the like. The display section 224 may display characters, symbols, images, etc. based on the information regarding the weight 40 determined by the determination section 213, for example, under the control of the output control section 214.

The acquisition unit 211 acquires information regarding a physical quantity related to an impact generated on the mold 30 when press working is performed. The acquisition unit 211 acquires, for example, information regarding the physical quantity output from the measurement unit 221. Alternatively, the acquisition unit 211 may acquire the information regarding the physical quantity from the external server via the communication unit 222, for example, when the information regarding the physical quantity is stored in an external server (not shown).

When the physical quantity acquired by the acquisition unit 211 is equal to or greater than a preset threshold, the calculation unit 212 calculates an attenuation ratio of the physical quantity such that the physical quantity related to the impact generated on the mold 30 during press working falls within a predetermined range. For example, when the frequency of a sound as a physical quantity is equal to or higher than a threshold value, the calculation unit 212 calculates an attenuation ratio at which the frequency of the sound falls within a predetermined range (predetermined frequency range). In this case, for example, when the sound generated during press processing has a frequency peak and the frequency peak of the sound is greater than or equal to a threshold value, the calculation unit 212 calculates a damping ratio that makes the frequency peak within a predetermined frequency range. . Note that the calculation unit 212 may calculate the above-mentioned attenuation ratio, for example, when the sound has a plurality of frequency peaks and the highest frequency peak is equal to or higher than a threshold value. In addition, the calculation unit 212 calculates the frequency range of the sound, for example, when the frequency has a band, that is, when there is a plurality of peaks in the frequency band of the sound that the worker feels uncomfortable (frequency above the threshold), or when the frequency band (frequency above the threshold) is unpleasant to the worker. If the amplitude of the frequency in the frequency band is relatively high, the attenuation ratio may be calculated such that the peak of the sound in that frequency band is within a predetermined range (predetermined frequency range).

Here, the threshold value in this case may be, for example, the value (frequency) of the lower limit (substantially lower limit) of the frequency band of the sound that the worker finds unpleasant. As an example, the frequency serving as the threshold value may be, for example, any value within the range of 2500 Hz to 3000 Hz, or may be any other value. Further, the predetermined range (predetermined frequency range) may be, for example, a frequency range in which a worker is unlikely to feel uncomfortable. As an example, the predetermined range (predetermined frequency range) may be, for example, a range of 500 Hz to 1000 Hz, or a range of other values.

Further, for example, when the sound level (volume) as a physical quantity is equal to or higher than a threshold value, the calculation unit 212 calculates an attenuation ratio at which the sound level falls within a predetermined range (predetermined level range). In this case, for example, if the sound generated during press processing has a frequency peak (sound level (volume)), and the amplitude of the frequency peak of the sound is greater than or equal to the threshold, the calculation unit 212 calculates the amplitude of the frequency peak. An attenuation ratio within a predetermined amplitude range (predetermined volume range) is calculated. Note that the calculation unit 212 may calculate the above-mentioned attenuation ratio, for example, when there are multiple frequency peaks of sound and when the amplitude of the frequency peak with the highest amplitude is equal to or greater than a threshold value. Further, for example, when there are multiple frequency peaks of a sound having an amplitude equal to or higher than a threshold value, the calculation unit 212 calculates the frequency peak having the highest amplitude, at least one peak among the multiple frequency peaks in a predetermined frequency range, and , an attenuation ratio at which at least one of relatively more frequency peaks falls within a predetermined range (predetermined volume range) may be calculated.

Here, the threshold value in this case may be, for example, the lower limit (substantially lower limit) value (volume) of the level (volume) of the sound that the worker feels uncomfortable. The lower limit (approximately lower limit) of the volume may be, for example, a volume at which the worker begins to feel uncomfortable. Further, the predetermined range (predetermined volume range) may be, for example, a volume range in which the worker is unlikely to feel uncomfortable.

The calculation unit 212 may calculate the damping ratio using, for example, CAE (Computer Aided Engineering). The calculation unit 212 can calculate the damping ratio, for example, by performing eigenvalue analysis using CAE on the model to be analyzed. For example, if there is a sound range (frequency band) that the worker feels uncomfortable, the calculation unit 212 can calculate the attenuation ratio by preparing multiple patterns of the weights 40 and re-analyzing them using CAE. can.

Alternatively, the calculation unit 212 (or the control unit 210, etc.) calculates, for example, the mold 30, the frequency and volume of the sound generated when the mold 30 is used, and the physical quantity of the sound that is felt to be unpleasant among the sounds. A learning model is generated by learning in advance information (damping ratio, weight of the weight 40, shape of the weight 40, etc.) of the weight 40 that can change (at least one of frequency and volume) (can reduce noise). Good too. Further, the calculation unit 212 may acquire the above-mentioned learning model generated externally. When the information on the physical quantity is acquired by the acquisition unit 211, the calculation unit 212 may calculate (specify) the weight 40 that can reduce noise based on the information on the physical quantity and the learning model.

The determining unit 213 determines a weight 40 having at least one of a weight and a shape according to the damping ratio calculated by the calculating unit 212.
In this case, for example, the storage unit 223 may store setting information in which the weight and shape of the weight 40 are set in advance according to the damping ratio. For example, when the damping ratio is calculated by the calculation unit 212, the determining unit 213 refers to the setting information stored in the storage unit 223 and determines the weight 40 having the weight and shape according to the damping ratio. Good too.
Alternatively, when the weight 40 is specified using the learning model in the calculation unit 212 as described above (when the weight and shape of the weight 40 are specified), the determination unit 213 determines whether the weight 40 is specified by the calculation unit 212. A weight 40 having a weight and shape may be determined.

The output control unit 214 controls the output unit to output information regarding the weight 40 determined by the determination unit 213. The output unit may be, for example, the communication unit 222, the storage unit 223, and the display unit 224.
For example, the output control unit 214 may control the communication unit 222 to transmit information regarding the weight 40 determined by the determination unit 213 to an external device.
For example, the output control unit 214 may control the storage unit 223 to store information regarding the weight 40 determined by the determination unit 213.
The output control unit 214 may control the display unit 224 to display characters, symbols, images, etc. based on the information regarding the weight 40 determined by the determination unit 213, for example.

Next, a method for manufacturing a workpiece (work 100) according to an embodiment will be described.
The method of manufacturing the workpiece (work 100) is a method of manufacturing the workpiece by performing press working using the mold 30.
FIG. 5 is a flowchart for explaining a method for manufacturing a workpiece (work 100) according to an embodiment.

In step ST101, the measuring unit 221 of the information processing device 200 measures a physical quantity related to the impact generated on the mold 30 when press working is performed (measuring step). In this case, the measurement unit 221 may measure, for example, a physical quantity related to sound as the physical quantity. The measurement unit 221 may measure, for example, the frequency of the sound generated when pressing is performed and the level (volume) of the sound generated when pressing is performed, as physical quantities (physical quantities related to sound). good. When measuring a physical quantity, the measuring unit 221 outputs information regarding the measured physical quantity to the control unit 210.
Note that an external measuring unit located outside the information processing device 200 measures a physical quantity related to the impact (for example, a physical quantity related to sound) generated in the mold 30 when press working is performed, and transmits the measurement results to the information processing device 200 (or , an external server, etc.).

In step ST102, the acquisition unit 211 of the information processing device 200 acquires information regarding the physical quantity measured in step ST101 (acquisition step). In this case, the acquisition unit 211 may acquire information regarding the physical quantity transmitted from the measurement unit 221 (or external measurement unit), or may acquire information regarding the physical quantity stored in an external server or the like. .

In step ST103, when the physical quantity measured in step ST101 is equal to or greater than a preset threshold, the calculation unit 212 of the information processing device 200 calculates a physical quantity such that the physical quantity related to the impact generated on the mold 30 during press working falls within a predetermined range. Calculate the damping ratio (calculation step).
For example, when the frequency of a sound as a physical quantity is equal to or higher than a threshold value, the calculation unit 212 calculates an attenuation ratio at which the frequency of the sound falls within a predetermined range (predetermined frequency range). In this case, for example, when the sound generated during press processing has a frequency peak and the frequency peak of the sound is greater than or equal to a threshold value, the calculation unit 212 calculates a damping ratio that makes the frequency peak within a predetermined frequency range. .
Further, for example, when the sound level (volume) as a physical quantity is equal to or higher than a threshold value, the calculation unit 212 calculates an attenuation ratio at which the sound level falls within a predetermined range (predetermined level range). In this case, for example, if the sound generated during press processing has a frequency peak (sound level (volume)), and the amplitude of the frequency peak of the sound is greater than or equal to the threshold, the calculation unit 212 calculates the amplitude of the frequency peak. An attenuation ratio within a predetermined amplitude range (predetermined volume range) is calculated.

In this case, the calculation unit 212 may calculate the damping ratio using CAE or the like, for example. The calculation unit 212 can calculate the damping ratio, for example, by performing eigenvalue analysis using CAE on the model to be analyzed.
Alternatively, the calculation unit 212 calculates, for example, the mold 30, the frequency and volume of the sound generated when the mold 30 is used, and the physical quantity (at least one of the frequency and volume) of the sound that is felt to be unpleasant. Based on a learning model that has previously learned information about the weight 40 (damping ratio, weight of the weight 40, shape of the weight 40, etc.) that can change the noise (can reduce noise) and information about the physical quantity acquired in step ST102. The weight 40 that can reduce noise may be calculated (specified).

In step ST104, the determining unit 213 of the information processing device 200 determines a weight 40 having at least one of a weight and a shape according to the damping ratio calculated in step ST103 (determining step).
In this case, for example, when the damping ratio is calculated by the calculation unit 212, the determining unit 213 refers to the above-mentioned setting information stored in the storage unit 223, and selects a weight having a weight and shape corresponding to the damping ratio. 40 may be determined.
Alternatively, when the weight 40 is specified using the learning model in the calculation unit 212 as described above (when the weight and shape of the weight 40 are specified), the determination unit 213 determines whether the weight 40 is specified by the calculation unit 212. A weight 40 having a weight and shape may be determined.

In step ST105, the output control unit 214 of the information processing device 200 controls the output unit to output information regarding the weight 40 determined in step ST104 (output step). Here, the output section may be, for example, the communication section 222, the storage section 223, and the display section 224.

In step ST106, an installation device (not shown) or the like installs the weight 40 determined in step ST104 on the mold 30 based on the information regarding the weight 40 output in step ST105 (installation step).
After step ST106 (installation step), the press device 1 is used to manufacture the workpiece (work 100).

Next, the effects of this embodiment will be explained.
The press device 1 has a mold 30 used for press processing of a workpiece, and a weight 40 disposed on the mold 30, which has at least one of a weight and a shape depending on the natural frequency of the mold 30. , is provided.
Thereby, the press device 1 can suppress noise generated during press processing. In addition, the press device 1 can suppress the impact noise generated during press processing from being felt by the worker as unpleasant, and can improve the working environment for the worker.
In other words, the press device 1 can install the weight 40 in the mold 30 according to the natural frequency of the mold 30, thereby eliminating discomfort during press molding of the molds 30 of different types and in preparation for production. Noise can be prevented by shifting the sound range (for example, lowering the relatively high range so that the peak is between 500 and 1000 Hz).

In the press device 1, the weight 40 may have at least one of a shape and weight that attenuates the sound generated based on the natural frequency of the mold 30 when pressing a workpiece.
Thereby, the press apparatus 1 can install the weight 40 in the mold 30, which can reduce the noise generated during press processing.

In the press device 1, the weight 40 may include a shim used for shim adjustment.
Thereby, the press apparatus 1 can improve the degree of freedom when adjusting the weight 40, and can install the weight 40 in the mold 30, which can further reduce noise generated during press processing. That is, in the press device 1, the damping ratio can be easily adjusted by using the shim-adjustable weight 40.

The manufacturing method of the workpiece (work 100) is a manufacturing method in which press working is performed using a mold 30, and the physical quantity related to the impact generated on the mold 30 when press working is performed. and a calculation step of calculating an attenuation ratio of the physical quantity such that the physical quantity related to the impact generated on the mold 30 during press working falls within a predetermined range when the physical quantity measured by the measuring step is equal to or greater than a preset threshold value. a determining step of determining a weight 40 having at least one of a weight and a shape according to the damping ratio calculated in the calculating step; and an installing step of installing the weight 40 determined in the determining step in the mold 30; Execute.
In the method for manufacturing the workpiece 100, a weight 40 that suppresses noise generated during press working can be installed in the mold 30. As a result, the method for manufacturing the workpiece 100 can prevent the worker from feeling uncomfortable about the impact noise generated during press working, and can improve the working environment for the worker.
