Description

  The present invention relates to a method for manufacturing a plate product cut by a plate processing machine on a surface inclined with respect to the thickness direction of the plate, and a plate processing machine using the manufacturing method.

  Conventionally, a steel plate is cut by a plasma processing machine, a laser processing machine, or a gas cutting machine using a thermal cutting method. Groove machining is performed by a 5-axis control machine that adds a torch swivel axis and a torch tilt axis to perform groove machining in addition to the 3-axis control of the X, Y, and Z axes corresponding to cutting of the outer periphery of the product. It has been broken.

  In groove processing having a root surface, first, the outer periphery of the product is thermally cut in a state where the torch is perpendicular to the steel plate, and then the groove surface is thermally cut with the torch being in an oblique state. After that, with the torch perpendicular to the plate material, cutting the plate material parallel to the thickness direction of the plate material is I-cut, and with the torch oblique to the plate material, the thickness direction of the plate material Inclination with respect to the cutting of the plate material will be referred to as V-cut.

  Patent Document 1 discloses a groove processing method capable of suppressing separation of a remaining material from a planned product portion when forming a groove shape portion in the planned product portion of the workpiece.

  In addition, when performing groove processing of a plate material by tilting the nozzle, prior to the groove processing, an opening window in which the inclined nozzle does not interfere with the plate material is formed by thermal cutting at a position where the groove processing is to be performed. Then, a groove processing method is disclosed in Patent Document 2 in which a nozzle is moved in the opening window to perform groove processing of a plate material.

JP 2009-241083 JP 9-155539 A

  Plasma processing machines, laser processing machines, and gas cutting machines using a thermal cutting method have a maximum cutting plate thickness that can be cut. The maximum cut plate thickness is the maximum plate thickness that can be cut when a plate material is cut vertically (I cut). For example, when a plasma processing machine is used to obliquely blow a plasma jet against a plate with the maximum cutting thickness, the equivalent plate thickness (cutting depth when cutting the plate diagonally) exceeds the maximum cutting thickness. So it can not be cut diagonally.

  Further, it is also impossible to perform groove processing by performing V-cut after performing I-cutting on a plate material having the maximum cut plate thickness because the equivalent plate thickness exceeds the maximum cut plate thickness. There is a problem that groove processing cannot be performed by I-cutting and then V-cutting unless the thickness of the equivalent plate is equal to or less than the maximum cutting thickness. The groove processing method using the thermal cutting method disclosed in Patent Document 1 cannot perform groove processing on a plate material having the same thickness as the maximum cutting plate thickness.

  As shown in FIG. 1, a processing machine using a thermal cutting method with a maximum cutting plate thickness of 25 mm is used to form a groove with a groove angle of 45 ° and a root surface of 8 mm on a plate material (S) having a plate thickness of 25 mm after I-cutting ( When the V-cut is performed, the remaining material (Z) after I-cutting is also partially processed, so the equivalent plate thickness is 35.4 mm, which is √2 times the plate thickness 25 mm, and the maximum cut plate thickness is 25 mm. Can not be grooved. The plate thickness that can be grooved with a groove angle of 45 ° is a plate material having an equivalent plate thickness of 25 mm or less, that is, a plate material having a plate thickness of 17.68 mm (25 / √2) or less.

  It is a processing machine that uses a thermal cutting method with a maximum cutting plate thickness of 25 mm. For plate materials with a plate thickness of 16 mm or less, V-cut after I-cut or I-cut after V-cut can be performed with a groove angle of 45 °. Is possible. However, in order to perform groove processing with a groove angle of 45 ° provided with a root surface on a plate material with a plate thickness exceeding 17.68 mm (25 / √2) or groove processing with a groove angle of 45 ° without a root surface. Beveling must be done in other ways. To perform groove processing by other methods, carry the I-cut product with a processing machine using a thermal cutting method into a dedicated machine and machine the groove, or manually gasify the groove. Must be cut. Therefore, there is a problem that the cost of carrying the groove processing product, the cost for groove processing with a dedicated machine, or the labor cost for manual groove processing are required.

  In the groove processing method of Patent Document 2, if the groove processing is performed on four sides of a square product, four opening windows must be processed around the four sides of the product. In other words, in order to perform groove processing on four sides of a square product, it is necessary to process the outer periphery of the square product and further process an opening window on four sides of the square. Therefore, there is a problem that the machining time is increased and the running cost is significantly increased.

  An object of the present invention is to solve the problems of the prior art as described above. Specifically, due to restrictions on the maximum cutting plate thickness in the plate material processing machine, cutting with a surface inclined with respect to the thickness direction of the plate material with respect to a plate material that could not be processed with a torch inclined until now An object of the present invention is to provide a manufacturing method of a plate material product that can be performed at a low running cost and a plate material processing machine that manufactures a plate material product using the manufacturing method.

  According to the first aspect of the present invention, the cutting is performed on the surface inclined with respect to the product after the remaining material is removed, so that the cutting is performed on the surface inclined with respect to the thickness direction of the product due to the restriction of the maximum cutting plate thickness. It becomes possible to manufacture plate products having a thickness that could not be processed. In addition, since it is not necessary to cut the opening window excessively in order to cut on the inclined surface with respect to the product after the remaining material is removed, the running cost for cutting the plate product can be manufactured at a low cost.

  According to the invention of claim 2, since the remaining material including the peripheral edge portion of the plate material is removed, a space is formed around each of a plurality of products to be processed obliquely. Since the space can be used to access the cut surface of the product after the torch has been I-cut, processing such as a back groove can be continuously performed on the lower surfaces of a plurality of products to be obliquely processed.

  According to the invention of claim 3, since the space is formed around the product after the remaining material is removed, the degree of freedom of the torch is increased, and the product when the torch is I-cut using the peripheral space of the product. Since the cutting surface can be approached, processing such as a back groove in which the lower surface of the product is cut obliquely can be performed.

  According to the invention of claim 4, the I-cut plate material can be removed by the apparatus for sorting, so that the productivity is improved.

  According to invention of Claims 5-6, since an I-cut board | plate material is mounted in the process pallet and a removal process is attained with the apparatus which sorts, productivity improves.

  The plate material processing machine 250 according to the embodiment of the present invention is a surface inclined with respect to the thickness direction of the plate material P in the three-axis control of the X axis, the Y axis, and the Z axis corresponding to the cutting of the outer periphery of the product S. In order to perform cutting processing, a 5-axis control laser processing machine to which a torch turning axis and a torch tilt axis are added is used. A processing pallet 255 is attached to the plate material processing machine 250. The processing pallet 255 transfers the plate material P placed on the skid 251 to the processing position at the plate material carry-in / out position. Thereafter, the plate material P on the skid 251 is cut by a torch 252 included in the plate material processing machine 250. Since laser processing machines are already well known, detailed description of laser processing machines is omitted.

  As the plate material P processed by the plate material processing machine 250, a regular plate material P is mainly used. Since the end of the regular plate P is bent or recessed, the product S having a closed loop outline is cut out (I cut), leaving the end of the plate P as shown in FIG. Therefore, the peripheral portion of the plate material P always becomes a remaining material Z (skeleton). The remaining material Z between the product S and the product S is connected to the remaining material Z in the peripheral portion. The processed plate material W is mainly divided into a remaining material Z (removed portion) including the peripheral portion of the plate material P and connected to each other, and a plurality of products S (non-removed portions). When the back groove is formed on the product S, the width dimension of the remaining material Z between the product S to be back and the other product S is such that the torch 252 interferes with the product S when the back groove is cut by V-cut described later. Not to be a width dimension.

  Next, a manufacturing method for manufacturing a plate product will be described. The processing pallet 255 of the plate material processing machine 250 is stopped at the plate material carry-in / out position. The plate material P is carried into a fixed position on the skid 251 of the processing pallet 255 of the plate material processing machine 250 by the sorting device. The processing pallet 255 is transferred to a processing position for cutting the plate material P by a transfer device (not shown) of the plate material processing machine 250. And the cutting process which cut | disconnects the outer periphery of the product S (I cut) in parallel with the thickness direction at the board | plate material P is performed. In the cutting step, the plate material P is cut to form the product S and the remaining material Z. After the cutting step, the processing pallet 255 is transferred to the plate material loading / unloading position by the transfer device.

  The processed plate material W formed into the product S and the remaining material Z on the processing pallet 255 is directly from the processed plate material W by the sorting device that sorts the processed plate material W into the product S and the remaining material Z. The removal process is performed by removing the residual material Z formed by cutting. In some cases, the processed plate material W is transported to a sorting device that sorts the processed plate material W into the product S and the remaining material Z, and the removal process is performed.

  The remaining material including the peripheral portion of the plate material P from the product S (non-removed portion) cut in the cutting process on the skid 251 of the processing pallet 255 and the remaining material Z (removal portion) including the peripheral portion of the plate material P. A removal step for removing Z (removal unit) is performed. After the removing step, the processing pallet 255 on which the product S is placed is transferred again to the processing position. And the inclination cutting process which cut | disconnects the product S by the surface which inclines with respect to the thickness direction (V cut) is performed. After the inclined cutting step, the processing pallet 255 is transferred to the plate material carry-in / out position by the transfer device, and the V-cut product S is carried out there. In this way, the plate product is manufactured.

  In the cutting step, the plate material P is placed in parallel to the thickness direction of the plate material P in a state where the torch 252 is perpendicular to the plate material P with respect to the plate material P placed on the skid 251 of the processing pallet 255. This is a process of cutting and forming the product S and the remaining material Z. The outer periphery of the product S is cut from the plate material P, and the product S is divided from the plate material P.

  In addition, the cutting step is a torch for the remaining material Z after the product S is processed on a part of the plate material P and the remaining material Z having a space for processing the product S and including the peripheral portion of the plate material P. It is also a step of forming the product S and the remaining material Z by cutting the plate material P in parallel with the thickness direction of the plate material P in a state where 252 is vertical.

  The conveyance process for conveying the product S and the remaining material Z together to the sorting apparatus will be briefly described with two examples.

  (1) The processing pallet 255 on which the processed plate material W formed on the product S and the remaining material Z is placed is transferred from the plate material processing machine 250 to the sorting device and conveyed.

  (2) The processing pallet 255 on which the processed plate material W formed on the product S and the remaining material Z is placed is transferred from the plate material processing machine 250 to the sorting device and conveyed to the storage shelf of the sorting device.

  The transporting process will be specifically described with reference to an example of a sorting apparatus to be described later.

  The removing step is a step of removing the remaining material Z including at least the peripheral edge portion of the plate material P cut in the cutting step without substantially changing the relative position of the products S to each other. By removing the remaining material Z including the peripheral edge of the plate material P, a space is formed around all the products S. Since the space can be used to access the cut surface of the product S after the torch 252 has been I-cut, processing such as a back groove can be continuously performed on the lower surfaces of the plurality of products S to be obliquely processed.

  The removal process for removing the remaining material Z will be briefly described with two examples.

  (1) The remaining material Z is removed directly from the processed plate material W placed on the skid 251 of the processing pallet 255.

  (2) The processed plate material W placed on the skid 251 of the processing pallet 255 is taken out and sorted into the product S and the remaining material Z, and the sorted product S is the same on the skid 251 of the processing pallet 255. Place in position.

  Further, the removing step may be a method of removing only the separated remaining material Z after separating only a part of the remaining material Z that interferes with the inclined cutting process of the product S from the remaining material Z. Regarding the removing step, a method of automatically removing the remaining material Z by an example of a sorting apparatus to be described later will be specifically described.

  In the inclined cutting process, the product S from which the remaining material Z has been removed is cut on a surface inclined with respect to the thickness direction of the product S with the torch 252 of the plate material processing machine 250 inclined (V cut). ). When oblique processing is performed on both the upper surface and the lower surface of the product S in the inclined cutting process, the torch 252 is in an inclined state and cut along the surface extending from the upper surface of the product S to the cutting surface when I-cut (V Cut). Then, in a state where the torch 252 is tilted in the direction opposite to the tilt of the first torch 252, cutting (V-cut) is performed on a surface extending from the cut surface at the time of I-cutting to the lower surface of the product S. Further, in the inclined cutting process, even if the outer periphery of the product S has a curved shape, the torch 252 of the plate material processing machine 250 is inclined and the torch 252 is moved along the outer peripheral curve of the product S. Cutting (V-cut) can be performed on a surface inclined with respect to the thickness direction of the product S. When V-cutting the product S having an unstable shape placed on the skid 251, a device for supporting the product S from below is provided so that the product S does not move and the product S does not tilt. May be processed.

  One side groove processing in the inclined cutting process will be described with reference to FIG. This occurs when the I-cut is performed if a groove processing is performed with a groove angle of 45 ° and a root surface of 8 mm on the product S with a plate thickness of 25 mm after the I-cut with a laser processing machine having a maximum cutting plate thickness of 25 mm. Since the remaining material Z is removed, the equivalent plate thickness is 24 mm, which is √2 times the root surface 8 mm drawn by 25 mm. Since the equivalent plate thickness is smaller than the maximum cut plate thickness, groove processing is possible. In the inclined cutting process of the one-side groove processing, the product S is cut by a surface inclined with respect to the cut surface on the outer periphery of the product S so that a part in the thickness direction of the cut surface when the product S is I-cut remains. When the groove surface is cut with respect to the lower surface of the product S (back groove), the remaining material Z is removed, so that the torch 252 is I-cut using the peripheral space of the product S formed by the removal process. It becomes possible to get close to the cut surface.

  The both-side groove processing in the inclined cutting process will be described with reference to FIG. On the product S with a plate thickness of 25 mm after I-cut with a laser processing machine with a maximum cutting plate thickness of 25 mm, groove processing (front groove) with a groove angle of 45 ° is performed upward from the center of the plate thickness. When groove processing (back groove) with a groove angle of 45 ° is performed from the center to the lower side, the equivalent plate thickness becomes 17.7 mm, which is √2 times half of the plate thickness of 25 mm. Since the equivalent plate thickness is smaller than the maximum cut plate thickness, groove processing is possible.

  The groove processing includes a front groove for processing a groove on the upper surface of the product S and a back groove for processing a groove on the lower surface of the product S. When cutting the product S having a groove with no root surface from the plate material P, the outer periphery without the groove processing is I-cut, and the portion to be groove processed is directly V-cut without the I-cut. When the groove processing is performed, the bottom surface of the back groove Z is processed so that the bottom surface is wider than the top surface. Therefore, even if an attempt is made to sort the product S and the remaining material Z by lifting the remaining material Z, the bottom surface of the remaining material Z becomes the product S. It is difficult to automatically sort by catching. From the viewpoint of sorting, the method of removing the remaining material Z and cutting the V into the product S after performing I-cutting is preferable from the viewpoint of increasing productivity.

  When nesting the product S for V-cutting the lower surface of the product S, a portion where the lower surface of the product S is V-cut may be disposed on the space 257 between the skid 251 and the skid 251. By doing so, when the torch 252 is tilted by the plate material processing machine 250 and the lower surface of the product S is V-cut, the upper part of the skid 251 can be simultaneously processed to prevent a part of the skid 251 from melting.

  The R chamfering process in the inclined cutting process will be described with reference to FIG. After the I-cut is performed by the plate material processing machine 250, the product S from which the remaining material Z has been removed is the angle (θ) from the cut surface of the I-cut to the inclined cut surface, that is, the angle (θ) from the so-called torch 252. When the V-cut is performed three times while changing the distance (L) from the cut surface of the I-cut to the torch 252, the edge processing is equal to or better than the 3-pass grinding processed at the free edge in the ballast tank Is possible. Further, in the inclined cutting process, the upper surface or the lower surface of the product S is changed a plurality of times, that is, at least three times by changing both the inclination angle of the surface to be inclined and cut with respect to the thickness direction of the product S and the position of the surface to be inclined and cut. By repeatedly cutting as described above, pseudo R chamfering with a larger R than 2R processing becomes possible. By changing the size of R at both ends of the pseudo R chamfering process, it becomes possible to process more complicated shapes.

  A slight positional deviation occurs in the I-cut product S within the range of the cut width generated when the plate material P is I-cut. After the remaining material Z is removed, V-cutting is performed on the product S in which a slight positional deviation has occurred. When the slight positional deviation affects the V-cut processing accuracy, an image of the product S may be taken with a CCD camera, and the positional deviation of the product S may be corrected to perform the V-cut. In addition, when the processed plate material W is taken out, sorted into the product S and the remaining material Z, and the product S is placed on the skid 251, the positional deviation of the product S affects the V-cut processing accuracy. In this case, an image of the product S may be taken with a CCD camera, and the position shift of the product S may be corrected to perform V-cut.

  At the upper part of the skid 251, there are a convex portion due to adhesion of dross generated when cutting the plate material P and a concave portion formed when the skid 251 is melted. Therefore, when the plate material P is I-cut, the position in the height direction of the product S may change with respect to the position in the height direction of the plate material P. After removing the remaining material Z, the product S in which the position in the height direction of the product S has been changed is V-cut. When the difference in the position in the height direction affects the processing accuracy of the V-cut, the V-cut start point and the V-cut end point are measured by a height measuring sensor. Then, the height and inclination of the product S are calculated based on the measured position value in the height direction and the measured position information. Correction may be made based on the position of the product S in the height direction and the inclination of the product S to perform V-cutting.

  Further, the processed plate material W is taken out, sorted into the product S and the remaining material Z, and the height of the product S when the product S is placed on the skid 251 and the plate material P before sorting. When the difference from the position in the height direction affects the V-cut machining accuracy, the groove machining start point and the groove machining end point are measured by a height measuring sensor. Then, the inclination of the product S is calculated from the measured height value and the measured position information. Correction may be made based on the position of the product S in the height direction and the inclination of the product S to perform V-cutting.

  The sorting apparatus according to the first embodiment will be described with reference to FIGS. 6 and 7. This sorting apparatus sorts the processed plate material W, which has been subjected to micro jointless processing (without the micro-connecting portion) by the plate material processing machine 250, into the product S and the remaining material Z. The sorting apparatus mainly includes a holding unit 400, a vertical movement unit 321, a sorting cart 281, and a table lifter 291.

  A table lifter 291 is installed at a position adjacent to the plate material processing machine 250. Rails 288 are respectively installed on both sides of the plate material processing machine 250 and the table lifter 291. In the sorting cart 281, the frame has a gate shape, and wheels described later roll on the rail 288 and can move between the table lifter 291 and the plate material processing machine 250. In the sorting cart 281, the plate material processing machine 250 side is referred to as a front side, and the table lifter 291 side is referred to as a rear side.

  Two bearing units 284 are attached to the left and right lower parts of the front side of the sorting cart 281 on the left and right sides, respectively, with the mounting surfaces facing upward. A wheel 282 is fixed to a shaft 285 that is rotatably supported by two bearing units 284 at the left front portion (see FIG. 6) of the sorting cart 281. A flanged wheel 283 is fixed to a shaft 285 that is rotatably supported by the two bearing units 284 at the right front portion of the sorting cart 281.

  A hollow shaft motor 286 and a bearing unit 284 are attached to the left and right lower portions of the left and right rear portions of the sorting cart 281 with the mounting surface facing upward. One end of the shaft 287 is fixed to the hollow shaft motor 286. The other end of the shaft 287 is rotatably supported by a bearing unit 284. A wheel 282 is fixed to the left rear shaft 287 of the sorting cart 281. A flanged wheel 283 is fixed to the right rear shaft 287 of the sorting cart 281. A vertical movement portion 321 is provided at the upper center of the gate-shaped frame of the sorting cart 281. The vertical movement part 321 includes a vertical cylinder 322, a connecting jig 323, and a pair of guides 324. An upper and lower cylinder 322 is attached to the upper surface of the frame of the sorting cart 281 with the rod facing downward, and a pair of guides 324 are attached to both sides thereof.

  The holding unit 400 includes a plurality of three-jaw chucks 401, a holder mounting frame 405, and a pair of guide bars 329. A holder mounting frame 405 is attached to the connecting jig 323 attached to the tip of the rod of the upper and lower cylinders 322. A guide bar 329 is vertically installed on the upper surface of the holder mounting frame 405. The holder attachment frame 405 is guided by a guide 324 attached in parallel to the upper and lower cylinders 322.

  A plurality of three-jaw chucks 401 are attached to the holder attachment frame 405 so that the claws of the three-jaw chucks 401 face downward. The inner nail 402 is attached to the nail. The inner claw 402 is tapered so that when the claw is closed, it is smaller than the hole diameter of the hole H processed in the remaining material Z and the tip is easily inserted into the hole H.

  When the product S is processed by the plate material processing machine 250, a plurality of holes H are processed at appropriate intervals in the peripheral portion of the plate material P. The hole H is machined to a position where it does not interfere with the skid 251 when the 3-jaw chuck 401 holds the remaining material Z. The 3-jaw chuck 401 inserts the inner claw 402 into the hole H, opens the inner claw 402 and holds the remaining material Z. Therefore, when the processed plate material W on the skid 251 is sorted, the center of the hole H processed in the peripheral portion of the plate material P and the axis of the 3-jaw chuck 401 mounted on the holder mounting frame 405 are obtained. The 3-jaw chuck 401 is disposed so as to coincide with each other vertically.
