Etc.

Conventionally, processing such as press processing using a processing device such as a die pressing device has been performed on a processing target (object) such as metal or resin. In mold processing such as press working, the quality of the mold affects the processing accuracy of the object. The quality of the mold deteriorates due to the increase in the number of times of use and the deterioration of the usage environment, and as a result, the processing accuracy also deteriorates. Therefore, it is important to maintain and improve the processing accuracy by properly maintaining the usage environment of the mold.

In order to maintain the usage environment of the mold, it is desirable to grasp and manage the mechanical characteristics generated between the mold and the processing target. For example, in Patent Document 1, a press machine capable of detecting the elongation of a frame by a strain sensor and converting the press load based on the correspondence between the detection value of the strain sensor stored in advance and the actual press load. The load measuring device of the above is disclosed.

[Embodiment 1]
<Explanation of die press equipment>
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of a die pressing apparatus (hereinafter, abbreviated as pressing apparatus) S as a processing apparatus according to the first embodiment. The press device S includes a drive motor 4, a transmission mechanism 6, a crankshaft 8, a connecting rod 10, and a slide 12 inside and outside the housing 2. Further, the press device S has a control unit 14, a display screen (display means) 16, an input unit (input means) 18, and a sensor (detection means) 24. The press device S of the first embodiment is a progressive press device, and further includes a plurality of processing stages 5 and a transfer mechanism (transport means) 28.

The drive motor 4 is, for example, a servomotor that is servo-controlled, and moves a mold 3 described later via a transmission mechanism 6, a crankshaft 8, and a connecting rod 10 while controlling a rotation amount and a rotation direction. The transmission mechanism 6 is configured to include, for example, a transmission member such as a gear or a belt, and transmits the rotation of the motor shaft of the drive motor 4 to the crankshaft 8. The control signal to the drive motor 4 is sent from the control unit 14.

The crankshaft 8 and the connecting rod 10 are for converting the rotational movement of the motor shaft transmitted by the transmission mechanism 6 into reciprocating movement (up and down movement in the first embodiment). The crankshaft 8 rotates due to the rotation of the motor shaft, and the rotation is transmitted to the connecting rod 10 whose one end is connected to the crankshaft 8 so that the connecting rod 10 moves up and down (moves up and down).

A slide 12 is connected near the other end of the connecting rod 10. As the connecting rod 10 moves up and down, the slide 12 moves up and down along a guide (not shown). As shown in the schematic view in FIG. 2, the slide 12 faces the bolster 22. In the press device S, the bolster 22 is arranged so as to face the slide 12. The upper mold 3a as a part of the mold 3 is mounted on the surface of the slide 12 facing the bolster 22 (lower surface in the first embodiment). The lower mold 3b as a part of the mold 3 is mounted on the surface of the bolster 22 facing the slide 12 (the upper surface in the first embodiment).

By arranging the work W as a processing target between the upper mold 3a and the lower mold 3b and pressing the work W with the upper mold 3a and the lower mold 3b, the work W is pressed by the press device S. Specifically, the drive motor 4 rotates under the control of the control unit 14. The rotation of the drive motor 4 is transmitted to the connecting rod 10 via the transmission mechanism 6 and the crankshaft 8, and the slide 12 moves up and down. The upper die 3a and the lower die 3b are pressed by the downward movement of the slide 12, and the work W is pressed. That is, in the press device S, the drive motor 4, the transmission mechanism 6, the crankshaft 8, the connecting rod 10, and the slide 12 form the press unit.

This press device S has a plurality of processing stages 5. The plurality of processing stages 5 include, for example, a processing stage (first processing stage) 51, a processing stage (second processing stage) 52, and a processing stage (third processing stage) 53. The press device S may have more machining stages (fourth and subsequent machining stages).

A mold 3 for each processing stage 5 is installed in each of the plurality of processing stages 5. For example, on the processing stage 51, a mold (first mold) 31 composed of an upper mold (first upper mold) 31a and a lower mold (first lower mold) 31b is installed. For example, a mold (second mold) 32 composed of an upper mold (second upper mold) 32a and a lower mold (second lower mold) 32b is installed on the processing stage 52. For example, on the processing stage 53, a mold (third mold) 33 composed of an upper mold (third upper mold) 33a and a lower mold (third lower mold) 33b is installed. If the press device S has more machining stages, a die is installed for each of those machining stages. Since the upper molds 31a to 33a are mounted on the same slide 12 and the lower molds 31b to 33b are mounted on the same bolster 22, a plurality of machining stages can be obtained by one press operation (one vertical movement) of the press portion. The machining in 51 to 53 is executed in parallel.

The dies 31 to 33 installed in each of the plurality of processing stages 51 to 53 realize different processing for the work W (processing target). For example, the die 31 is drawn, the die 32 is bent, and the die 33 is punched. The plurality of processing stages 51 to 53 are arranged in a series in the press device S. For example, as shown in FIG. 2, the plurality of processing stages 51 to 53 may be linearly arranged in a row. Further, as another example, a plurality of processing stages 51 to 53 may be arranged in a series in an arc shape.

The transport mechanism 28 is for sequentially transporting the work W toward the plurality of processing stages 51 to 53. The transport mechanism 28 has, for example, a drive motor, a drive transmission mechanism, and the like. The roll-shaped or sheet-shaped metal material WS as the raw material of the work W is drawn into the pressing device S by the transport mechanism 28 and sent to the processing stage 51. The work W temporarily stopped at the processing stage 51 is processed by the mold 31 and sent to the processing stage 52 by the transport mechanism 28. The work W temporarily stopped at the processing stage 52 is processed by the mold 32 and sent to the processing stage 53 by the transport mechanism 28. The work W temporarily stopped at the processing stage 53 is processed by the die 33 and sent to the subsequent processing stages by the transfer mechanism 28, or discharged to the outside of the press device S.

The display screen 16 is for displaying the operating status of the press device S, setting parameters, and the like. The display screen 16 is composed of, for example, a liquid crystal monitor, an LED display device, a CRT, or the like. The input unit 18 is for inputting an operation command (for example, on, off, etc.) of the press device S, a setting parameter, and the like. The input unit 18 is composed of, for example, a keyboard, buttons, switches, a touch panel, and the like. Both the display screen 16 and the input unit 18 are connected to the control unit 14. The information input from the input unit 18 is sent to the control unit 14, and the display screen 16 displays the information based on the display information sent from the control unit 14.

The display screen 16 also displays machining information regarding the mechanical properties generated between the dies 31 to 33 and the work W for each of the plurality of machining stages 51 to 53. In the first embodiment, the mechanical property is the compressive force generated between the molds 31 to 33 and the work W. The display screen 16 displays information on the surface pressure and load factor for each of the machining stages 51 to 53 as machining information on the compressive force, which will be described in detail later. Of course, mechanical properties and processing information are not limited to these.

The sensor 24 is for detecting the mechanical characteristics (compressive force in the first embodiment) generated between the die 3 and the work W when the press device S presses the work W. The sensor 24 does not detect the compressive force of each of the machining stages 51 to 53, but detects the compressive force of the entire plurality of machining stages of one press working by the press device S. That is, the total compressive force when the press device S performs press working is detected in a state where a plurality of work Ws are arranged in each of the plurality of machining stages 51 to 53. The sensor 24 may be, for example, a strain gauge installed in the housing 2. Further, when detecting a mechanical characteristic other than the compressive force, a sensor corresponding to each mechanical characteristic to be detected is used. The sensor 24 may be installed at any position of the connecting rod 10 (for example, a position near the center).

As shown in FIG. 3, the control unit 14 has a CPU 14a as an arithmetic processing means and a memory 14b as a storage means inside. The CPU 14a is connected to the drive motor 4, the display screen 16, and the input unit 18. The control unit 14 has a function of calculating the compressive force for each processing stage 51 to 53 based on the detection result by the sensor 24. Further, a function of calculating the surface pressure on the molds 31 to 33 for each processing stage 51 to 53 based on the mold area of the molds 31 to 33 for each processing stage 51 to 53 and the above-mentioned compressive force is provided. Have. Further, each processing stage 51 to 53 has a function of calculating a load factor which is a ratio of the compressive strength and the surface pressure of the molds 31 to 33. These details will be described later.

<Detection process>
In the press device S, the roll-shaped or sheet-shaped metal material WS as the raw material of the work W is sent to the processing stage 51 by the transport mechanism 28. At this time, the upper die 3a and the lower die 3b are in an open state in the processing stage 51, and the work W is conveyed and placed between them. The head work W at the start of machining is referred to as work W1. When the work W1 stops at a predetermined position on the machining stage 51, the press portion operates, the upper die 3a and the lower die 3b are closed, and machining of the work W1 on the machining stage 51 is executed.

The processing on the work W1 is realized by press processing at a high pressure by the press unit. The compressive force (also referred to as press load) on the work W1 during press working is detected by the sensor 24 installed in the housing 2. When the sensor 24 is a strain gauge, the sensor 24 detects the strain (elongation) of the housing 2 during press working (detection step). Then, the detection result is sent to the control unit 14, and the CPU 14a calculates the compressive force generated between the mold 3 and the work W1 based on the detection result. Including the process of calculating the compressive force by the CPU 14a, it is said that "the compressive force is detected by the sensor 24". When the work W1 exists only in the machining stage 51, this compressive force is the compressive force between the mold 31 and the work W1 in the machining stage 51.

When the machining of the work W1 on the machining stage 51 is completed, the press portion opens the die 3. The transport mechanism 28 transports the work W1 to the machining stage 52, and at the same time, transports the next work W2 to the machining stage 51. When the work W1 is placed between the upper and lower dies 32 of the machining stage 52 and the work W2 is placed between the upper and lower dies 31 of the machining stage 51 and the transfer is stopped, the press portion operates and the upper die 3a and the lower die 3a are placed. The mold 3b is closed. As a result, the press working on the work W1 at the machining stage 52 and the press working on the work W2 at the machining stage 51 are executed.

The processing on the workpieces W1 and W2 is realized by press processing at high pressure by the press unit. The compressive force on the workpieces W1 and W2 at the time of press working is detected by the sensor 24 installed in the housing 2 as described above. When the work W1 is present in the machining stage 52 and the work W2 is present in the machining stage 51, this compressive force is the compressive force between the mold 32 and the work W1 in the machining stage 52 and the mold in the machining stage 51. It is the sum of the compressive force between 31 and the work W2.

When the machining of the workpieces W1 and W2 on the machining stages 52 and 51 is completed, the press portion opens the die 3. The transport mechanism 28 transports the workpieces W1 and W2 to the machining stages 53 and 52, respectively, and also transports the next work W3 to the machining stage 51. The work W1 is placed between the upper and lower dies 33 of the machining stage 53, the work W2 is placed between the upper and lower dies 32 of the machining stage 52, and the work W3 is placed between the upper and lower dies 31 of the machining stage 51. When the transfer is stopped, the press portion operates and the upper die 3a and the lower die 3b are closed. As a result, press working on the work W1 on the machining stage 53, press working on the work W2 on the machining stage 52, and press working on the work W3 on the machining stage 51 are executed.

The processing on the workpieces W1 to W3 is realized by press processing at a high pressure by the pressing portion. The compressive force on the workpieces W1 to W3 during the press working is detected by the sensor 24 installed in the housing 2 as described above. When the work W1 is present in the machining stage 53, the work W2 is present in the machining stage 52, and the work W3 is present in the machining stage 51, this compressive force is applied between the mold 33 and the work W1 in the machining stage 53. It is the sum of the compressive force of the above, the compressive force between the mold 32 and the work W2 in 52, and the compressive force between the mold 31 and the work W3 in the machining stage 51.

Hereinafter, each time the metal material WS is transferred to the processing stage 5 on the downstream side one after another by the transfer mechanism 28, the sensor 24 detects the compressive force generated between the mold 3 and the work W. The compressive force generated between the mold 3 and the work W by the sensor 24 is detected as a total value even when a plurality of work Ws are present in the plurality of machining stages 5. The compressive force F detected by the sensor 24 is F (1) for the compressive force at the machining stage 51, F (2) for the compressive force at the machining stage 52, and F (3) for the compressive force at the machining stage 53. When you do
-When only the work W1 exists in the machining stage 51: F = F (1)
-When the work W1 exists in the machining stage 52 and the work W2 exists in the machining stage 51: F = F (1) + F (2)
When the work W1 exists in the machining stage 53, the work W2 exists in the machining stage 52, and the work W3 exists in the machining stage 51: F = F (1) + F (2) + F (3)
Will be.

である。ここで、Ｆ（ｎ）は、ｎ番目の加工ステージでの圧縮力である。 When rewritten,
-When the work W exists up to the nth machining stage 5:
F = F (1) + F (2) + F (3) + ... + F (n-1) + F (n)

Is. Here, F (n) is the compressive force at the nth processing stage.

A coil spring (not shown) for releasing the work W from the mold 3 when the mold is opened may be arranged on each processing stage 5. In this case, the sensor 24 detects the compressive force (press load) including the compressive force (release force) by the coil spring at each processing stage 5.

<Calculation process>
When the compressive force from the sensor 24 is sent to the control unit 14, the CPU 14a calculates the compressive force for each machining stage 5 (calculation step). The compressive force for each processing stage 5 is obtained by the difference between the current value of the compressive force detected by the sensor 24 and the immediately preceding value of the compressive force detected by the sensor 24. Specifically, based on the total value of the compressive forces of the machining stages 5 in which the work W exists, the individual compressive forces of each machining stage 5 are calculated by the following equation (1).

となる。 F (n) = F- {F (1) + F (2) + F (3) + ... + F (n-1)}

Will be.

FIG. 4 is a data structure diagram of a mold information database (hereinafter, simply referred to as a database) D stored in the memory 14b of the control unit 14. The database D is stored in the memory 14b in advance by inputting information via the input unit 18, for example. The database D stores information on the mold area A for each mold 3 mounted on each processing stage 5 and information on the compressive strength T for each mold 3. For example, in FIG. 4, the mold area of the mold 31 of the processing stage 51 is A (1), and the compressive strength is T (1). The mold area of the mold 32 of the processing stage 52 is A (2), and the compressive strength is T (2). The mold area of the mold 33 of the processing stage 53 is A (3), and the compressive strength is T (3).

Here, the die area A of the die 3 is an area to which a press load is applied between the die 3 and the work W when the work W is pressed by the die 3. In general, the mold area A does not mean the area of the entire mold 3, but is a value close to the area of the work W processed by the mold 3. The compressive strength T of the mold 3 is a mechanical property peculiar to the material of the mold 3. When a compressive force F exceeding the compressive strength T is applied to the mold 3, the mold 3 may be deformed, distorted, or broken.

The CPU 14a calculates the surface pressure (compressive stress) P for each mold 3 of each processing stage 5 based on the compressive force F detected by the sensor 24 and the value of the mold area A of the database D. The surface pressure P is the pressure due to the press load applied to the die, and is given by (press load F on the die) / (mold area A). For example, as shown in FIG. 5, the surface pressure P (n) in the mold 3 of the nth processing stage 5 is P (n) = F (n) / A (n).

The CPU 14a calculates the load factor R for each mold 3 of each processing stage 5 based on the surface pressure P of the mold 3 and the value of the compressive strength T of the database D. The load factor R is given by the ratio of the surface pressure P to the mold and the compressive strength T (surface pressure P / compressive strength T), and the compressive strength T of the mold 3 is applied to the press load F applied thereto. It is a value indicating how much margin there is. For example, as shown in FIG. 5, the load factor R (n) in the die 3 of the nth machining stage 5 is R (n) = P (n) / T (n).

Here, the case where the press load is not applied (F = P = 0) is the state of the load factor R = 0. When the press load F becomes large and the load factor R ≧ 1 (= 100%), the surface pressure P is at least the compressive strength T. At this time, the compressive strength T has no margin with respect to the press load F, and the die 3 may be deformed, distorted, or broken.

<Display process>
Based on the detection result detected by the sensor 24 and the calculation result calculated by the control unit 14, the machining information 11 for each machining stage 5 is displayed on the display screen 16 (display process). FIG. 6 is a diagram showing a display example on the display screen 16 of the press device S. In FIG. 6, the compressive force (press load) F, the mold area A, the surface pressure P, the compressive strength T, and the load factor R are listed for each of the machining stages 51, 52, 53 ... By visually recognizing the display screen 16 by the user of the press device S, the margin of the compressive strength T of the die 3 with respect to the press load F for each processing stage 5 can be easily grasped. Here, the compressive force F is the processing information 11. Of course, the surface pressure P and the load factor R displayed on the display screen 16 together with the compressive force F are also machining information 11. The load factor R is also load factor information.

Since it is possible to easily grasp which processing stage 5 the compressive strength T of the mold 3 has a small margin with respect to the press load F, the material of the mold 3 can be appropriately selected for each processing stage 5. .. For example, when the margin is small or absent, the mold 3 in the processing stage 5 can be changed to a material having a higher compressive strength T.

FIG. 7A is a diagram showing another display example on the display screen 16 of the press device S. In FIG. 7A, the load factor R is displayed by the bar display 13 as a load factor meter for each mold 3 (for each machining stage 5). In FIG. 7A, the bar display 13 is the load factor information as the machining information 11. The bar display 13 visually displays the degree of the load factor R as a ratio of the length to the total length when the load factor is 100%.

For example, in the range of the load factor of 0 to 50%, the die 3 has a sufficient compressive strength T with respect to the press load F, and the die 3 may be deformed or broken by the load press load F. There is no area (safety area). The range of the load factor of 51% to 74% is a region (elastic deformation region) in which the mold 3 may be elastically deformed by the press load F. The range of the loading factor of 75% to 90% is a region (plastic deformation region) in which the mold 3 may undergo plastic deformation. The range of the load factor of 91% or more is a region (dangerous region) where the mold 3 may be seriously damaged such as plastic deformation and breakage.

In FIG. 7A, the bar display 13 corresponds to green in the range corresponding to the load factor R of 0 to 50%, and the bar display 13 corresponds to yellow and 75% to 90% in the range corresponding to 51% to 74%. In the range, the bar display 13 is displayed in red. When the load factor R is 91% or more, the bar display 13 is displayed in red, and the characters “Danger !!” are displayed in the bar display 13. By presenting the load factor R on the bar display 13 as described above, the user can intuitively and easily grasp the margin for the press load F of the die 3 for each machining stage 5.

FIG. 7B is a diagram showing still another display example on the display screen 16 of the press device S. In FIG. 7B, the load factor R is displayed as a load factor meter on the meter display 15 by the rotating needle for each mold 3 (for each machining stage 5). In FIG. 7B, the meter display 15 is the load factor information as the machining information 11. The meter display 15 visually displays the degree of the load factor R by the ratio of the rotation angle of the rotating needle to the center angle from the load factor 0 to the load factor 100%.

In the meter display 15, for example, the range of the load factor 0 to 50% is the "safety region", the range of the load factor 51% to 74% is the "elastic deformation region", and the range of the load factor 75% to 90% is "plasticity". It is displayed in characters that the range of "deformation area" and load factor of 91% or more corresponds to "danger area". By presenting the load factor R on the meter display 15 as described above, the user can intuitively and easily grasp the margin for the press load F of the die 3 for each machining stage 5.
