[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a servo press in which a slide is driven by an electric servo motor.Slide position setting methodAbout.
[0002]
[Prior art]
The servo press has a slide that is driven up and down by an electric servo motor at the top of the press machine, and the speed of the electric servo motor is controlled by a servo amplifier. And it is comprised so that a press work may be performed between the upper mold | type attached to the lower surface of the said slide, and the lower mold | type attached to the upper surface of the bolster provided in the lower part of the servo press.
[0003]
In the case of press working with the servo press as described above, a predetermined motion curve of the slide is set in advance, and the slide is controlled according to this motion curve. FIG. 6 shows an example of this motion curve. In the figure, the vertical axis represents the stroke length of the slide, and the horizontal axis represents the elapsed time.
[0004]
As shown in the figure, first, in the descending region, the slide is lowered from the upper limit position A to the pressurization start position B at a high speed. Here, the pressurization start position B represents a position in the vicinity of the material placed on the upper surface of the lower mold, and is usually set immediately before the lower surface of the upper mold contacts the material. Next, while lowering the slide from the pressurization start position B to the lower limit position C at a low speed, this material is press-molded and pressed. This lower limit position C is a position where the material is pressed between the upper mold and the lower mold to complete the molding. Then, while the slide is positioned at the lower limit position C, a predetermined pressure is maintained for a predetermined pressurizing time. A region from the pressurization start position B to the pressurization holding end point D is referred to as a molding region. After completion of this processing, the slide is raised at a low speed to a predetermined pressurization end position E, and then raised at a high speed to a stroke completion position F (equal to the upper limit position A) to complete one stroke. Note that the region from the pressurization pressure holding end point D to the stroke completion position F is referred to as an ascending region.
[0005]
Then, a position that becomes a switching point (hereinafter referred to as a point) of the slide control in each of the above areas is set in advance and stored in a controller (not shown), and this set position is used in subsequent press working. The slide is automatically controlled based on the above.
[0006]
Conventionally, as one method for setting each point of the motion curve, a method of providing limit switches and the like at the upper limit position A, the lower limit position C, the pressurization start position B, and the like is well known. In this case, the point of each area is detected by the operation of the limit switch.
[0007]
In addition, as another setting method, in the same operation as in the case of a mechanical press, a press test is performed, and while actually observing the positional relationship with the mold and the processing quality of the test workpiece, There is a method for setting the optimum position of each point on the slide. Below, the setting method of each point by this trial hitting operation is demonstrated. Normally, the press operation mode at the time of such setting work is performed in the “inching mode”, but this mode keeps pressing the operation button (generally, by left and right hand operation to ensure safety). In this mode, the slide can be moved at a predetermined low speed.
[0008]
First, in the inching mode, the operator moves the slide to a predetermined position that should be the upper limit position A, and stores this position in the controller (not shown) as the upper limit position A. Next, in order to set the pressurization start position B, the operation button is continuously pressed to lower the slide from the upper limit position A to the vicinity of the pressurization start position B, and when the slide approaches the pressurization start position B. In order to prevent interference between the upper mold and the lower mold, the operation button is pushed down for a short time like an inching operation to lower the slide by a minute distance. Then, when it is visually confirmed that the slide has come to a position where the upper mold is substantially in contact with the material placed on the upper surface of the lower mold, this position is set as a pressurization start position B.
[0009]
Next, the operator performs the same inching operation from the pressurization start position B, gradually lowers the slide while pressurizing the material, and can be regarded as the completion of molding immediately before the position where the upper mold substantially contacts the lower mold. Search for the lower limit position C. At this time, in order to confirm that the quality of the workpiece molded product at the time of this trial hitting is the best, the slide is lifted by a predetermined distance and the molded product is visually observed to obtain an optimum quality that provides good quality. This trial operation is repeated until the lower limit position C is found. Then, when it is determined that it is good, this lower limit position C is stored.
[0010]
When the setting of the lower limit position C is completed, the operator raises the slide to a predetermined pressurization end position E by an inching operation. The pressurization end position E is a position where the upper mold and the molded product are sufficiently separated, and the pressurization end position E is stored in the controller. Thereafter, the operator continues to push the operation button to raise the slide 3 at a predetermined low speed, and moves to the stroke completion position F (upper limit position A) to complete a series of setting operations.
[0011]
[Problems to be solved by the invention]
However, the following problems have arisen in the setting method of the upper limit position A, the lower limit position C, etc. concerning the above prior art.
In the method of setting the upper limit position A, the lower limit position C, etc. by the limit switch, the position of the limit switch cannot be fixed with high accuracy, so the setting of the lower limit position C often varies. For this reason, the upper mold and the lower mold interfere with each other at the lower limit position C, and in the worst case, the mold may be damaged.
[0012]
Further, the method for obtaining and setting the optimum position of each point by trial hitting as described above has the following problems.
The pressurization start position B is a position where the upper die substantially contacts the upper surface of the material, and the slide is lowered at a predetermined low speed to the pressurization start position B in the lowering region. On the other hand, in order to shorten the press working time, it is desired to set the pressurization start position B as close to the material as possible. Therefore, in order to move the slide as close to the material as possible, the operator needs to perform the inching operation very carefully while observing the gap between the lower surface of the upper die and the material when the upper die reaches the vicinity of the material. is there.
However, in the inching operation using the operation button, it is very difficult to control the amount of slide movement, and skill is required. In particular, when the worker is an unskilled person, the variation in the movement amount is large, and it is very difficult to accurately operate the movement amount for each minute movement amount. For this reason, workability | operativity and operativity are falling.
[0013]
Further, when setting the lower limit position C, the operator needs to lower the slide by a minute distance by an inching operation as described above to a position that seems to be optimal. At this time, if the setting position of the lower limit position C is mistaken, the mold may be damaged due to interference, so a considerable degree of skill is also required for this work. Moreover, since even a skilled person must carry out very carefully, it takes a lot of time, the workability is poor, and the mental burden is also large, so there is a problem that the degree of fatigue is large.
[0014]
  The present invention has been made paying attention to the above problems, and even an unskilled worker can easily and accurately set the slide position.Servo press slide position setting methodThe purpose is to provide.

Furthermore, since the lower limit position can be set to an optimum position while visually checking the gap between the upper mold and the lower mold and the quality of the molded product, a good quality of the molded product can be obtained. As a result, the operability and workability during the position setting operation can be improved, and the quality of the molded product can be improved.

DETAILED DESCRIPTION OF THE INVENTION
  The servo press according to the present invention will be described below.Slide position setting methodWill be described in detail with reference to FIGS.
[0021]
FIG. 1 shows a side view of an essential part showing an example of a servo press.
A bed 9 is provided in the lower front portion of the frame 2 of the main body of the servo press 1, and a bolster 7 is installed on the upper portion of the bed 9. In addition, a power conversion device 4 configured by, for example, a ball screw or the like that converts rotational power into a linear motion in the vertical direction is disposed on the upper portion of the frame 2, and a linear motion portion of the power conversion device 4 (for example, a ball screw) The slide 3 is arranged at the lower end of the nut portion of the apparatus and at a position facing the bolster 7 so as to be movable up and down. The upper end portion of the rotating portion of the power conversion device 4 (for example, the ball screw portion of the ball screw device) is connected to the output rotating shaft 15 b of the electric servo motor 15 via the rotation transmitting member 16. In the present embodiment, a belt (hereinafter referred to as belt 16) is used as illustrated as an example of the rotation transmission member 16, and the upper end portion of the rotating portion of the power conversion device 4 and the electric servo motor 15. A belt pulley 16a and a belt pulley 16b that engage with the belt 16 are attached to the output rotating shaft 15b. In this way, the slide 3 is driven up and down by the rotation of the electric servo motor 15 and operates according to a predetermined motion curve set in advance. The slide 3 moves up and down to the upper surface of the bolster 7. Press work is performed between the lower mold (not shown) provided and the upper mold (not shown) provided on the lower surface of the slide 3.
[0022]
A speed sensor 15a such as an encoder is attached on the opposite side of the output rotation shaft 15b of the electric servo motor 15 and coaxially with the output rotation shaft 15b. A speed signal from the speed sensor 15a will be described later. Input to servo amplifier. The electric servo motor 15 may be constituted by either an AC servo motor or a DC servo motor.
[0023]
In addition, an opening 2a opened in a C shape is provided on the front surface of the frame 2, and an auxiliary frame 5 having a C shape substantially similar to the opening 2a is disposed in the vicinity of the opening 2a. And this auxiliary | assistant frame 5 is attached to the side surface of the flame | frame 2 by the pin 8 so that it can displace up and down freely. Further, a slide position detecting means 6 comprising a linear sensor or the like is disposed between the upper end side of the auxiliary frame 5 and the rear side of the slide 3.
[0024]
The slide position detecting means 6 has a sensor rod 6a whose axial center direction is parallel to the moving direction of the slide 3 and supported by the rear portion of the slide 3, and is fitted into the sensor rod 6a, and the auxiliary frame 5 and a sensor head 6b attached to the upper end side. As the slide 3 moves up and down, the sensor rod 6a moves up and down with respect to the sensor head 6b. As a result, the position of the slide 3 is raised from the upper surface of the bolster 7 by the position detector inside the sensor head 6b. It is supposed to be detected as. A position signal detected by the slide position detecting means 6 is input to a controller which will be described later, and the controller drives the electric servo motor 15 based on the position signal to control the position of the slide 3.
Note that the detection accuracy of the slide position detecting means 6 enables control of the minute movement of the slide 3, and is a distance (for example, a smaller distance than the minimum unit necessary for setting the upper and lower limit positions, for example) 1/10 of the minimum moving distance).
[0025]
FIG. 2 is a block diagram of the hardware configuration of the servo press position setting apparatus according to the present invention.
The movement amount command input means 10 outputs a movement amount command for moving the slide 3 by a predetermined minute movement amount to the controller 13, and this movement amount command corresponds to the operation amount of the operator of the movement amount command input means 10. Proportionally output. That is, when the movement amount command input means 10 is composed of, for example, a manual pulser, a movement command pulse train having a predetermined number of pulses corresponding to the magnitude of the operation rotation angle of the manual pulser is output. The pulse is configured to correspond to a predetermined minimum movement amount. The slow speed operation switch 11 enables minute movement by the movement amount command input means 10 and outputs a movement permission command to the controller 13 while this switch is operated. Further, the mode selection switch 12 is a switch for selecting an operation mode. At least a “setup inching mode” that allows a minute movement by the movement amount command input means 10 can be selected. It is output to the controller 13.
[0026]
The position setting means 18 stores the current slide position data in association with each upper limit position A, lower limit position C, pressurization start position B, and pressurization end position E shown in FIG. The position setting means 18 is composed of, for example, a position selection switch for selecting a type to be set from among the position types to be taught at the time of setting, a storage switch for instructing to capture and store the current position, and the like. The position selection signal and the storage command output from each of these switches are output to the controller 13.
[0027]
The controller 13 is composed mainly of a microcomputer, for example. The controller 13 moves the movement amount only when the setup inching mode signal from the mode selection switch 12 is input and while the movement permission command from the slow speed operation switch 11 is input. A speed command for moving the slide 3 by a distance proportional to the magnitude of the movement amount command from the command input means 10 (in the case of a manual pulser, the number of movement command pulses) is output to the servo amplifier 14. During movement in the setup inching mode, the controller 13 inputs the slide position signal fed back from the slide position detecting means 6 and determines whether the target position separated by the moving distance has been reached. Further, when a position selection signal and a storage command are input from the position setting means 18, the controller 13 takes in the slide position signal and uses this position data as position data of the teaching position type corresponding to the position selection signal. Remember.
[0028]
The servo amplifier 14 inputs the speed command from the controller 13 and also inputs the speed signal from the speed sensor 15a as a feedback signal so that the speed deviation between the speed command and the feedback signal is reduced. Speed servo control is performed by controlling the current of the electric servo motor 15. This servo amplifier 14 can be constituted by a general servo amplifier that drives a servo motor, and is mainly composed of an analog servo circuit using an operational amplifier or the like, or a computer or a digital signal processing IC (so-called DSP). The digital servo circuit can be used.
[0029]
FIG. 3 shows a functional block diagram of the position setting device.
The movement amount command input means 10 includes, for example, a manual pulser 20, a pulse detection means 21, and a command value generation means 22. The manual pulser 20 has an operation unit such as a manually operated handle that can be rotated. When the manual handle is rotated by a predetermined angle by an operator, a predetermined number of pulses proportional to the rotation angle are arranged in time series. The pulse train signal is output to the pulse detection means 21. The pulse detecting means 21 detects the level change of the pulse train signal, counts the number of pulses, and outputs the count value of the number of pulses to the command value generating means 22. The command value generating means 22 outputs a movement amount command proportional to the magnitude of the input count value to the command output validity determining means 23.
[0030]
Further, as described above, the slow speed operation switch 11 enables minute movement of the slide 3 by the movement amount command input means 10 (that is, the manual pulser 20 or the like), and a movement permission command is issued while this switch is operated. It outputs to the command output validity judgment means 23. Similarly, the mode selection switch 12 outputs the setup dimensioning mode signal to the command output validity determining means 23 when the “setup dimensioning mode” is selected.
[0031]
The command output validity determining means 23 is configured so that the slide 3 moves by a distance proportional to the magnitude of the movement amount command only when the setup dimensioning mode signal and the movement permission command are input. And a position command is output to the speed command output means 24.
The speed command output means 24 inputs this position command and the position feedback signal from the slide position detection means 6 to calculate the position deviation between them, and outputs the speed command to the servo amplifier 14 so as to reduce this position deviation. To do. The magnitude of the speed command at this time may be, for example, a predetermined constant speed value set in advance, or may be a value proportional to the cycle time of the pulse train from the manual pulser 20. When the speed command is a constant speed value, the speed of the slide 3 may be selectively controllable within a range of (1/100) mm / s to 1 mm / s.
[0032]
The servo amplifier 14 controls the speed of the electric servo motor 15 based on this speed command as described above. As a result, the slide 3 is driven up and down at a predetermined fine speed by a distance corresponding to the magnitude of the movement amount command from the movement amount command input means 10.
[0033]
When the manual pulser 20 is used, the slide movement amount per unit pulse of the output is set to an extremely minute distance of, for example, about (1/100) mm, so that the minute movement can be controlled.
[0034]
Further, the storage device 28 stores the slide position at this time based on a command from the position setting means 18. That is, when the operator operates the position setting unit 18, the position selection signal and the storage command are output from the position setting unit 18 to the storage device 28. Then, the position data from the slide position detecting means 6 is taken into the storage device 28 and stored in the storage area for the position data of the teaching position type corresponding to the position selection signal.
[0035]
FIG. 4 is an explanatory diagram of the position setting means 18. In the present embodiment, an example is shown in which the position setting means 18 is configured by a character display and a setting switch.
In the figure, the position setting means 18 comprises a character display 31, a cursor movement key 32, and a storage switch 33. The character display 31 is composed of, for example, an EL display, a plasma display, a liquid crystal display, a CRT, or the like, and the figure shows a table in which a setup dimension moving image screen for position setting is displayed on the character display 31. An example is shown. The cursor movement key 32 is a key for moving the displayed cursor 34, and the storage switch 33 is an operation switch for capturing and storing the current position data of the slide 3 as described above.
[0036]
The setting operation by the position setting means 18 is performed according to the following procedure. First, the cursor movement key 32 is operated to move the cursor 34 in the vertical direction, and the teaching position type is selected. In the present embodiment, the teaching position type is displayed in the order of a lower limit position, a pressurization start position, a pressurization end position, and an upper limit position. When the storage switch 33 is operated after this position selection, the current position data is stored in the storage area corresponding to the selected teaching position type in the storage device 28. In addition, after all the position data is set, there is no contradiction in the positional relationship between the set data (for example, the lower limit position C is below the upper limit position A, or the pressurization start position B is the upper limit position A). And the lower limit position C, etc.) are checked, and if there is a contradiction, an error is displayed on the character display 31.
[0037]
Next, a processing flowchart representing the setting method by the position setting device described so far will be described with reference to FIG.
First, in step 101 (command output validity determination means 23), the controller 13 receives whether a setup inching mode signal of the mode selection switch 12 is input and whether a movement permission command of the slow speed operation switch 11 is input. Determine whether. When both are input, the process proceeds to step 102, and when at least one of them is not input, the process proceeds to end processing and ends without processing.
[0038]
In step 102 (command output validity determination means 23), the controller 13 inputs a movement amount command from the movement amount command input means 10, that is, a movement amount command proportional to the number of command pulses from the manual pulser 20, and then In step 103, a target position command is calculated so as to move by a movement amount proportional to the magnitude of the movement amount command. Thereafter, in step 104 (speed command output means 24), a position deviation between the target position command and the position feedback signal input from the slide position detection means 6 is calculated. In step 105 (speed command output means 24), a speed command is calculated so that the calculated position deviation becomes zero, and this speed command is output to the servo amplifier 14. As a result, the servo amplifier 14 controls the speed of the electric servo motor 15 based on the speed command. Then, by repeating the processing of steps 104 to 105 in the same manner as the normal feedback control loop processing, the slide 3 is accurately moved by the amount of movement commanded by the manual pulser 20 and positioned at the target position.
[0039]
Next, in step 106, the operator moves the cursor 34 by the cursor movement key 32 as described above, and selects the teaching position type. In step 107, the controller 13 determines whether or not the storage switch 33 is turned on, that is, whether or not a storage command is input from the storage switch 33. If not, the controller 13 repeats step 107 and waits until it is turned on. . When the storage switch 33 is turned on, in step 108 (storage device 28), the controller 13 inputs the position signal from the slide position detecting means 6, and the position data at this time is the teaching selected in the previous step 106. Store in the storage area corresponding to the position.
[0040]
As described above, according to the position setting device and method of this servo press, in the setup inching mode, it is proportional to the operation amount of the movement amount command input means 10 (for example, the operation rotation angle of the manual pulser 20). Since the slide 3 can be moved by a minute movement amount, the minute movement can be easily and accurately performed by adjusting the operation amount. In addition, since the slide is driven by servo control by an electric servo motor, when the operator inputs the operation amount, the slide is positioned with good response according to the operation amount, and a predetermined position on the motion curve is set. Sometimes operability is improved. Therefore, since the operator can easily and accurately perform the minute movement of the slide 3 regardless of the skill level, the operability and workability in moving the slide position at the time of trial strike can be improved. Then, it is possible to set the optimum slide position while confirming the quality of the molded product when the test is actually performed. For example, the pressurization start position and pressurization end position can be set as close as possible to the material, so that the high-speed descending region and the high-speed ascending region can be set long, and the press working time can be shortened. In addition, since the lower limit position C can be set at an optimal position where the molding quality is good and the mold interference can be prevented, the molding quality can be improved and the mold breakage can be prevented. .
[0041]
In this embodiment, the position setting means 18 includes the character display 31, the cursor movement key 32, and the storage switch 33. However, the present invention is not limited to this, and the teaching position type can be selected. There may be a storage switch that can store position data corresponding to the selected position type.
