Description

  The present invention relates to a plate material processing machine that processes a plate material with a punch press or the like, and a plate material processing method and a plate material processing program using the plate material processing machine.

  Conventionally, in Japanese Patent Publication No. 54-37350 (Patent Document 1), a plurality of clamping devices for clamping materials are arranged on the X-axis and Y-axis on a slide table movable in the X-axis and Y-axis directions of a press machine. Thus, there is disclosed a press machine that is configured to clamp a material from two directions and that can arbitrarily set intervals between the plurality of material clamping devices according to the size of the material.

  Further, JP 2007-54875 A (Patent Document 2) discloses a plate material feeding member that is movable back and forth and right and left, and a plate material that is installed on the plate material feeding member and can be moved forward and backward with respect to the plate material feeding member.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a plate material processing machine, a plate material processing method, and a plate material processing program according to the present invention will be described in detail with reference to the accompanying drawings. The plate material processing method according to the present invention is implemented using the plate material processing machine and the plate material processing program according to the present invention.

  First, an embodiment of the plate material processing machine 1 will be described with reference to FIGS. 1 to 4. 1 is a plan view for explaining a plate material processing machine 1 according to an embodiment of the present invention, FIG. 2 is a left side view of the plate material processing machine 1 shown in FIG. 1, and FIG. 3 is a plate material processing machine 1 shown in FIG. FIG. 4 is a diagram for explaining a state in which the Y-axis clamps 50a and 150b are moved in the plate material processing machine 1 shown in FIG.

  As shown in FIGS. 1 and 2, the plate material processing machine 1 of the present embodiment includes a press device 10 and a plate material positioning device 30. The press apparatus 10 includes a mold unit 12 and a press mechanism (only the striker 11 is illustrated). The mold unit 12 includes a mold bed 13 and a processing head 20. The mold bed 13 is provided on a frame (not shown), and the processing head 20 is installed on the mold bed 13.

  The machining head 20 includes a yoke 21 having an opening 22 that is substantially U-shaped in a side view, and a punch unit 23 provided near the tip of the yoke 21. As the punch unit 23, various types such as for punching, for punching to remove a part of the plate material, or for cutting can be employed. Further, a plurality of machining heads 20 are provided in parallel in the X-axis direction on the mold bed 13, and any machining head 20 is moved in the Y-axis direction using the slide groove 14 to be pulled out to the machining position. Can be fixed. Then, the striker 11 is used by operating the upper die of the punch unit 23.

  The plate material positioning device 30 includes a positioning bed 31, a slide table 32, an X-axis drive mechanism 33 and a Y-axis drive mechanism 34 that move the slide table 32 in the X-axis direction and the Y-axis direction, and a slide table 32 in the Z-axis direction. A Z-axis drive mechanism (not shown) to be moved, a plurality of X-axis clamps 40a and 40b, a plurality of Y-axis clamps 50a and 50b, a Y-axis clamp slide mechanism 55, and a second X-axis clamp 60. .

  The positioning bed 31 supports an X-axis drive mechanism 33, a Y-axis drive mechanism 34, and a Z-axis drive mechanism provided on the upper surface or the left side surface thereof.

  The X-axis drive mechanism 33, the Y-axis drive mechanism 34, and the Z-axis drive mechanism are configured by known air cylinders, ball screws, linear motion bearings, and the like, and support the slide table 32 and the X-axis, Y-axis, and Z-axis. It is moved to a desired position. When the plate material wo1 on the slide table 32 is moved to the machining position, the Z-axis drive mechanism slightly raises the plate material wo1 so as not to interfere with the lower mold of the punch unit 23, and when the plate material wo1 reaches the machining position. The plate material wo 1 is lowered and placed on the lower mold of the punch unit 23. Since the X-axis drive mechanism 33 is provided on the Y-axis drive mechanism 34, the X-axis drive mechanism 33 moves in the Y-axis direction together with the slide table 32 when the Y-axis drive mechanism 34 is operated.

  The slide table 32 can be moved to desired positions on the X, Y, and Z axes as described above, and the X axis clamps 40a and 40b, the Y axis clamps 50a and 50b, and the like are provided thereon.

  Two X-axis clamps 40a and 40b are provided in parallel in the X-axis direction of the slide table 32. The upper claw 41, a clamp body 42 having a lower claw, an upper claw drive mechanism 43, and an X-axis clamp forward / reverse mechanism 44. Then, by opening and closing the upper claw 41 with the upper claw driving mechanism 43, the plate material wo1 can be grasped or released between the clamp main body 42 including the upper claw 41 and the lower claw. Further, the X-axis clamps 40 a and 40 b can be advanced or retracted individually by the X-axis clamp forward / reverse mechanism 44.

  Two Y-axis clamps 50a and 50b are provided in parallel in the Y-axis direction of the slide table 32, and include a clamp body having an upper claw and a lower claw, an upper claw drive mechanism, a Y-axis clamp forward / reverse mechanism (both (Not shown), and has the same configuration as the above X-axis clamp. Then, by opening and closing the upper nail with the upper nail driving mechanism, the plate material wo1 can be held or released between the clamp main bodies having the upper nail and the lower nail. Further, the Y-axis clamps 50a and 50b can be moved forward or backward individually by the Y-axis clamp forward / backward moving mechanism. The Y-axis clamps 50a and 50b are shown by broken lines in FIG. 2 because the configuration is substantially the same as the X-axis clamps 40a and 40b and other configurations are easy to see.

  Further, as shown in FIG. 4, the Y-axis clamp farthest from the X-axis 70 in which the X-axis clamps 40a and 40b are arranged in parallel, which is the processing head 20 side (back side) of the two Y-axis clamps 50a and 150b. The claw 151 of 150b can be extended to the opposite side to the X axis 70.

  Similarly, as shown in FIG. 4, the Y-axis clamp slide mechanism 55 moves the Y-axis clamps 50a and 150b in the Y-axis direction. In the plate material processing machine 1 of this embodiment, the Y-axis clamps 50a and 150b are processed. It can be moved to the X-axis clamps 40a, 40b, which are the opposite side (front side) of the head 20, and can be substantially parallel to the X-axis clamps 40a, 40b in the X-axis direction. Although not shown, as another embodiment, the Y-axis clamp slide mechanism 55 can be extended to the processing head 20 side, and the Y-axis clamps 50a and 50b can be moved to the processing head 20 side.

  Returning to FIG. 1, the distance d1 between the farthest ends of the two X-axis clamps 40a and 40b and the two Y-axis clamps 50a and 50b is preferably 150 mm or less, and more preferably 130 mm or less. In the plate material processing machine 1 of this embodiment, the distance d1 is set to 125 to 130 mm. Further, the distance d2 between the two X-axis clamps 40a and 40b and between the two Y-axis clamps 50a and 50b is preferably 60 mm or less and 30 mm or more. In the plate material processing machine 1 of the present embodiment, the distance d2 is set to 35 to 40 mm. By setting the distances d1 and d2 between the two X-axis clamps 40a and 40b and between the two Y-axis clamps 50a and 50b in this way, the length of one side is 200 mm, and the plate material is about 100 to 80 mm. Even so, it can be gripped and processed by four clamps. Further, by using only two clamps, that is, the X-axis clamp 40a and the Y-axis clamp 50a, without using four clamps, even a plate material having a side length of about 30 mm can be directly processed.

  In addition, although it is the lower limit of the distance d1 between the ends of the two X-axis clamps 40a and 40b and the two Y-axis clamps 50a and 50b, the clamp has a strength capable of gripping the plate material with a sufficient force. Depends on the width dimension. A preferable distance for the lower limit is a dimension obtained by adding the widths of the individual clamps and the above-mentioned separation distance d2, and an absolute lower limit is a dimension obtained by adding the widths of the individual clamps. The lower limit of the width of the clamp is, for example, about 10 mm. Accordingly, the preferable lower limit of the distance d1 between the end portions is 55 to 60 mm, and the absolute lower limit is 20 mm.

  Similarly, as shown in FIG. 1, the width d3 of the portion of the punch unit 23 that abuts against the plate material is preferably smaller than the separation distance d2 between the plurality of X-axis clamps 40a and 40b. Thereby, when processing the intermediate position of the plurality of X-axis clamps 40a and 40b or in the vicinity of the intermediate position, the plate material wo1 can be gripped by at least one of the two X-axis clamps 40a and 40b. .

  Further, as shown in FIG. 2, the yoke 21 of the machining head 20 has a distance d4 from the back of the substantially U-shaped opening 22 to the punch unit 23 in the side view, which is the largest of the plurality of Y-axis clamps 50a and 50b. The plate material wo1 to be processed from the end on the processing head 20 side is longer than the distance d5 in the Y-axis direction from the end farthest from the processing head 20 and longer than the Y-axis dimension d6 of the plate material wo1 to be processed. Is preferred. Thus, when the front Y-axis clamp 50 a is moved backward to avoid a dead zone and the place is processed by the punch unit 23, the back-side Y-axis clamp 50 b can be inserted into the opening 22 of the yoke 21. Thus, interference between the Y-axis clamp 50b and the yoke 21 can be prevented.

  As shown in FIG. 3, the second X-axis clamp 60 is provided in the X-axis drive mechanism 33 and is configured to be independently movable in the X-axis direction. The second X-axis clamp 60 is movable in the X-axis direction relative to the X-axis clamps 40 a and 40 b and the Y-axis clamps 50 a and 50 b provided on the slide table 32. The second X-axis clamp 60 is configured to be retractable when not in use, such as when the plate member wo2 is not gripped, by a second X-axis clamp forward / reverse mechanism (not shown).

  Next, referring to FIG. 1 to FIG. 7, based on each component of the plate material processing machine 1 described above, the operation of the plate material processing machine 1, the plate material processing method and the plate material processing program using the plate material processing machine 1 explain. 1 to 4 are as described above. 5 to 7 are views for explaining a plate material processing method according to an embodiment of the present invention. The plate material processing program is executed by a control unit, a storage unit, a display unit, an operation unit, and the like provided on a control panel (not shown) of the plate material processing machine 1 to operate the plate material processing machine 1 to realize a plate material processing method. .

  First, with reference to FIG. 1, a method for processing a plate material cut in advance to a predetermined dimension will be described. Before starting the processing, the slide table 32 is in the retracted position, and the X-axis clamps 40a and 40b and the Y-axis clamps 50a and 50b on the slide table 32 are all opened. In this state, when the plate material wo1 is gripped by the X-axis clamps 40a and 40b and the Y-axis clamps 50a and 50b and the plate material processing machine 1 is operated, the necessary processing head 20 is pulled out to the processing position. Next, the slide table 32 is raised to a position where the plate material wo1 does not interfere with the lower mold of the punch unit 23 by the Z-axis drive mechanism. Next, the slide table 32 is moved by the X-axis drive mechanism 33 and the Y-axis drive mechanism 34, and the plate material wo1 is moved to the processing position. Next, the slide table 32 is lowered by the Z-axis drive mechanism so that the plate material wo <b> 1 is placed on the lower mold of the punch unit 23.

  Then, the punch unit 23 provided in the processing head 20 performs processing such as drilling and chamfering the plate material wo1. Here, if necessary, the used processing head 20 can be retracted to the mold bed 13, and another processing head 20 can be pulled out to the processing position to process the plate material wo <b> 1 using the plurality of punch units 23. Next, when the slide table 32 is moved onto a shooter (not shown) and the X-axis clamps 40a and 40b and the Y-axis clamps 50a and 50b are opened, the processed plate material wo1 is discharged.

  5 to 7, when processing the plate material wo1, when the processing head 20 and the X-axis clamps 40a, 40b or the Y-axis clamps 50a, 50b interfere continuously at a plurality of processing positions, A plate material processing method for avoiding these interferences will be described. 5 to 7 are enlarged views around the slide table 32 in FIG. As shown in FIG. 5A, when the machining head 20 and the right X-axis clamp 40b interfere with each other at the first machining position p1, the interfering right X-axis clamp 40b is moved backward by the X-axis clamp forward / reverse mechanism. Let Thus, the plate material wo1 can be gripped and processed by the remaining three X-axis clamps 40a and Y-axis clamps 50a and 50b.

  Next, as shown in FIG. 5B, when the machining head 20 and the left X-axis clamp 40a interfere at the next machining position p2, the interfering left X-axis clamp 40a is moved forward and backward by the X-axis clamp. Retreat by. Then, the slide table 32 is moved to the next processing position p2 with the shortest distance. Thus, the plate material wo1 can be held by the remaining two Y-axis clamps 50a and 50b, and the plate material can be moved and processed. Further, when the movement of the plate material wo1 is finished, the right side X-axis clamp 40b may be advanced as needed to hold the plate material wo1 (in the plate material processing method of FIGS. 6A and 6B described later). The same is true.)

  Next, different patterns will be described. As shown in FIG. 6A, the machining head 20 and the right X-axis clamp 40b interfere with each other at the first machining position p1, and the machining head 20 and the front Y-axis clamp 50a at the next machining position p3. In the case of interference, the right X-axis clamp 40b and the front Y-axis clamp 50a are retracted when the plate material wo1 is moved after the processing at the processing position p1 is completed. Accordingly, the plate material can be moved to the next processing position by the shortest distance while the plate material wo1 is gripped by the remaining two X-axis clamps 40a and Y-axis clamps 50b.

  The plate material processing machine 1 of the present embodiment includes a yoke 21 having a substantially U-shaped opening 22 in a side view and a punch unit 23 provided in the vicinity of the tip of the yoke 21, As shown in FIG. 6A, even if the Y-axis clamp 50b holding the plate material wo1 is on the far side from the processing position p3, the Y-axis clamp 50b enters the space of the opening 22 of the yoke 21, and the yoke 21 And the rear Y-axis clamp 50b do not interfere with each other.

  Next, as shown in FIG. 6B, the machining head 20 and the right X-axis clamp 40b interfere at the first machining position p1, and the machining head 20 and the rear Y-axis clamp at the next machining position p4. When 50b interferes, the right X-axis clamp 40b and the back Y-axis clamp 50b are retracted when the plate material wo1 is moved. Thereby, the plate material can be moved to the next processing position by the shortest distance while the plate material wo1 is gripped by the remaining two X-axis clamps 40a and Y-axis clamps 50a.

  Further, different patterns will be described. As shown in FIG. 7A, when the machining head 20, the left X-axis clamp 40a and the front Y-axis clamp 50a interfere with each other at the first machining position p5, the two clamps are already retracted. If the plate material wo1 is moved in the direction of the arrow in the drawing, the machining head 20 interferes with any remaining X-axis clamp 40b or Y-axis clamp 50b at the next machining position, and these clamps are retracted. If it does, the clamp which hold | grips board | plate material wo1 will become one. In such a case, the direction of the plate material wo1 is rotated by 180 degrees, and the first processing position p5 is set to a position where none of the processing head 20, the four X-axis clamps 40a and 40b, and the Y-axis clamps 50a and 50b interfere. Thus, wherever the next processing position is, it is possible to always hold the plate material with a plurality of clamps while moving the plate material wo1 at the shortest distance to the next processing position. In addition, also when moving from the processing position p1 shown in FIG. 5 (A) to the processing position p5 shown in FIG. 7 (A), by rotating the direction of the plate material wo1 by 180 degrees, the plate material is always held by a plurality of clamps. It can be gripped.

  Next, with reference to FIG.3 and FIG.4, the board | plate material processing method of a elongate material is demonstrated. In FIG. 3, the plate material wo2 whose length in the X-axis direction is shorter than the moving distance of the slide table 32 in the X-axis direction is processed. Here, the vicinity of the left end of the plate material wo2 is held by the X-axis clamps 40a and 40b and the Y-axis clamps 50a and 50b. Further, the vicinity of the right end of the plate material wo2 is held by the second X-axis clamp 60. The second X-axis clamp 60 prevents the right end of the plate material wo2 from drooping due to the weight of the plate material, and improves the positioning accuracy of the plate material wo2.

  Next, when the processing near the right end of the plate material wo2 is finished by the processing head 20 equipped with the punch unit 23 for drilling or the like, the processing head 20 is returned to the mold bed 13. Next, another processing head 20 equipped with the cutting punch unit 23 is pulled out from the mold bed 13, and the plate material wo2 is cut at, for example, a broken line c in the drawing. And the cut | disconnected board | plate material should just be discharged | emitted from the shooter which is not shown in figure. Next, only the second X-axis clamp 60 is opened, the slide table 32 is moved to the right in the X-axis direction, the plate material wo2 is sent to the right, and the second X-axis clamp 60 is closed. Then, the processing of the plate material by the processing head 20 may be repeated. Further, the plate material wo2 can be processed as a long material without being cut.

  Moreover, in FIG. 4, the board | plate material processing method of a longer elongate material is demonstrated. 4, the configuration is the same as that of FIG. 3 except for the Y-axis clamps 50a and 150b. The Y-axis clamps 50 a and 150 b are moved to the near side by the Y-axis clamp slide mechanism 55 and are substantially parallel to the X-axis clamps 40 a and 40 b and the X-axis 70. Of the two Y-axis clamps 50a and 150b, the claw 151 of the Y-axis clamp 150b on the back side is extended to the back side.

  As a result, even if a long material longer than the moving distance of the slide table 32 in the X-axis direction, for example, a long material wo3 such as a roll material, the Y-axis clamps 50a and 150b do not get in the way, and the top of the slide table 32 Can pass through. Further, the plate material wo3 can also be gripped by the Y-axis clamp 150b, and the plate material wo3 can be stabilized. Moreover, even if it is not a long material, since the variation of the position of Y-axis clamp 50a, 150b increases, it can respond to various processes. The specific processing method is the same as that in FIG. 3 except that the positions of the Y-axis clamps 50a and 150b are different.

  As described above, according to the plate material processing machine, the plate material processing method, and the plate material processing program of this embodiment, the processing head is provided in the vicinity of the front end of the yoke having a substantially U-shaped opening in side view. Since the punch unit is provided, the plate material can be processed while avoiding the clamp on the processing head side from the processing position, and there is no dead zone. In addition, since multiple machining heads are provided and any machining head can be pulled out to the machining position, various punch units can be installed for drilling, chamfering, and cutting, and various machining can be performed. .

  Furthermore, two X-axis clamps and two Y-axis clamps are provided for the X-axis and Y-axis, respectively, so that the plate material can be retracted individually, so that the plate material can always be held by a plurality of clamps, and when the plate material is moved and processed A shift in time can be prevented. In addition, the plate material can be moved to the next processing position at the shortest distance while always gripping the plate material with a plurality of clamps, and the processing time can be shortened.

  In a general processing device called a turret punch, it is possible to punch a small product from a large plate while using a plurality of punch units, but there is a bridge between the peripheral parts of the plate and between products, generating scrap. It was inevitable. Further, even if a small plate material is directly processed, the turret interferes with a clamp holding the plate material, and the processing is difficult.

  On the other hand, according to the plate material processing machine, the plate material processing method, and the plate material processing program of the present embodiment, even if the length of one side of the plate material to be processed is as small as 100 mm or less, the plate material is directly gripped with a plurality of clamps. It can be processed, and a dead zone can also be avoided, and only a portion where scrap is generated by punching with a punch unit.

  Furthermore, since the second X-axis clamp and the Y-axis clamp slide mechanism are provided, it is possible to use a long material obtained by extending only the dimension in the X-axis direction without changing the dimension in the Y-axis direction of the plate material. Thereby, it is possible to perform continuous processing while sequentially feeding the plate material in the X-axis direction while maintaining the feature that there is no dead zone and there is little scrap. Furthermore, since a small plate material or a long material short in the Y-axis direction can be directly processed, it is suitable for the production of a small variety of products.

  Note that the plate material processing machine, the plate material processing method, and the plate material processing program of the above-described embodiment are examples of the present invention, and the configuration thereof can be changed as appropriate without departing from the spirit of the invention.
