- the cover 15 9 made of rubber, soft resin, or the like is used.
- the elevating member 13 7 is covered. Since the other mechanisms described above are also covered by the power members 15 3 and 15 55, contact with workers is avoided and safety is ensured.
- the servo motor 79 rotates, and the locating member 144 (navigating member) is moved in the left-right direction (Y-axis direction).
- the moving support is manually set.
- the current position of the locating member 144 in the left-right direction (Y-axis direction) is displayed.
- the manual pulsar was rotated to operate the moving servomotor 79, and the locating member 144 (navigating member) was located at a desired position.
- the operation of the manual pulser is stopped, and the rotation of the servomotor 79 is stopped (S4).
- an appropriate correction position of the locating member 144 was determined and positioned. Therefore, the operator manually pressed the execution button 163 as a setting button (S5).
- the correction value according to is input to the storage unit 37 (FIG. 13). Once the correction value is input to the storage section 37, the locating member 144 is automatically positioned at the above-described correction position in the next production lot. Therefore, if a veteran performs the correction work using the first manual pulse, even a beginner can perform bending work at the same level as a veteran in the next processing.
- the skilled operator displays 1 to 4 in the leftmost column of the table shown below the window 157 based on his / her own judgment. Instruct the “valid Z” (same screen) of the work navigation function along each bending order 1 to 4 and set the target position for work navigation positioning.
- either the left or right side of the work navigation abutment member should be brought into contact with the end face or end of the work, or how much each pull side (avoidance movement) should be, and For example, whether or not to raise the work navigation member by 5 millimeters from the normal work navigation position is set arbitrarily, and stored in the storage unit 37, and in the case of a repeat product, By calling the above values in the process from the storage unit 37, appropriate processing can be performed.
- FIG. 13 Since the same NC device as the NC device 95 in the bending machine according to the third embodiment can be used as the NC device, a detailed description of the configuration of the NC device will be omitted.
- the back gauges 1733 and 1775 are provided on a carriage 171, which is movable in the X-axis direction, so as to be movable in the Y-axis direction.
- Abutting members 177 and 179 are provided at the tips of the respective knock gauges 173 and 175. Further, as shown in FIG. 21, the abutting members 177, 179 are provided with port members 181, 183 movable in the X-axis direction, as shown in FIG.
- the abutting member 177 is moved to a position indicated by a two-dot chain line in FIG. Then, the operator slides the downward bending die 5 in the Y-axis direction and abuts against the abutting member 177, whereby the downward bending die 5 is moved to a predetermined position in the Y-axis direction.
- the mold 5 can be positioned and fixed.
- the positioning and fixing of the downward bending die 5 is performed.
- the workpiece W in the X-axis direction, is abutted against the abutting members 177 and 179, and in the Y-axis direction, the workpiece W is abutted on the locating member 183. This is done by striking.
- the other locating member 18 1 is retracted as shown in FIG. 22A.
- the positioning in the X-axis direction is performed in the same manner as described above.
- the positioning in the Y-axis direction is performed by abutting the workpiece W against the locating member 18 1. In this case, the other locating member 183 is retracted as shown in FIG. 22B.
- the moving servomotor control unit 97 shown in FIG. 13 is improved to have three axes, and three moving servomotors 79 are also provided.
- the total movement of the carriage 171 in the X-axis direction and the movement of the respective knock gauges 173 and 1775 in the Y-axis direction are obtained. Three axes will be controlled.
- the locating member 144 is so arranged that the locating member 144 avoids interference with the work W. A mode in which 1 4 5 is moved will be described.
- the bending order information, the mold layout information, the product information, and the work position information are input (S11), and in the CPU 33, an appropriate predetermined value for the lower bending mold of the work W is obtained. Calculate the position in the Y-axis direction that satisfies the relationship (S12).
- the CPU 33 shown in FIG. 13 calculates the amount of movement in the Y-axis direction for moving the location member 144 away from the work (S14).
- the CPU 33 calculates whether or not the locating member 144 interferes with the work. (S15).
- step 16 if it is determined in step 16 that there are two or more candidates for the work navigation abutment position, a weight is assigned to which of the plurality of candidates for the work navigation abutment position is the optimum position.
- the CPU 33 calculates the evaluation, determines the work navigation abutment position which is the most optimal position, and displays it on the display device 25 3 (FIG. 19) of the CPU 33 to display the operator. (S18).
- the operator should determine which side of the plurality of sides of the work should be abutted against the work navigation abutment member (left side or right side). This makes it easy to understand the position of the workpiece, making it possible to properly position the workpiece in the left-right direction.
- the operator strikes the workpiece against the locating member 144 in the Y-axis direction according to the determined work navigation abutting position. Positioning in the Y-axis direction with respect to the lower bending die 5 can be performed.
- a work follower as a device usually associated with a bending machine. Since both ends of the workpiece rotate upwards from the mold, the hand of the robot itself follows upwards from the force S that the hand of the mouth robot does not hold.
- the work follower can be moved to a predetermined position not only in the Y-axis direction but also in the X-axis direction as in the above-described back gauge. Therefore, by providing the above-mentioned locating member (navigating pin) on the above-mentioned robot hand, the same operation and effect as those of the second to fourth embodiments are achieved. Things.
- Japanese Patent Application No. 200-2 3008988 (filed on October 23, 2000).
- Japanese Patent Application No. 200-3 3 5 7 2 6 No. 9 (filed on Oct. 17, 2003) is incorporated herein by reference.
