Description

  The present invention relates to a profile processing apparatus for processing a profile cut to a predetermined length.

  Building materials such as sash window frames are manufactured by pressing or cutting an aluminum profile cut to a predetermined length. The cutting process is a process (for example, small-diameter drilling, salamomi, etc.) performed on a portion that requires higher accuracy than press processing, and a numerically controlled machine tool is usually used. In order to increase the accuracy of the cutting process, a mechanism for firmly holding the shape member at the target position is important.

  For example, a conventional processing device disclosed in Patent Document 1 includes a longitudinal positioning device that positions a workpiece in the longitudinal direction (X direction) with a predetermined stopper and a pressing member, and a slide rail attached to the main body. And a clamp device having four clamp units movable in the X direction. The two clamp units positioned at both ends in the longitudinal direction of the work piece sandwich the side faces of both ends of the work piece, and the two inner clamp units (the number can be increased) are the side faces of the intermediate part of the work piece. Pinch. The position in the X direction of each clamp unit other than both ends can be automatically adjusted by an interval adjusting device that operates in response to a command from the control device. The clamp unit at one end can be adjusted by a support length adjusting mechanism. The distance between the adjacent movable clamp units can be changed.

They are arranged in order at intervals of less than or equal to the length, and clamp the side portions of the profiles.

  The auxiliary vice adjacent to the main movable vise is movable, and when the length of the profile is shorter than the distance from the origin position to the main fixed vise, the control unit is connected to the profile holding unit. When holding the profile, the length of the profile protruding outward from the main movable vice and the auxiliary vice is set to the first length while the main movable vice is disposed in the vicinity of the origin position in the longitudinal direction.

  Hereinafter, an embodiment of a shape processing apparatus of the present invention will be described with reference to the drawings. The profile processing apparatus 10 of this embodiment is an apparatus for performing press working and cutting on the profile W1 cut to a predetermined length. As shown in FIGS. The carrying-in apparatus 12, the press processing part 14, the automatic transfer apparatus 16, the cutting process part 18, and the shape material carrying-out apparatus which is not shown in figure are provided.

  The shape material W1 is a long material obtained by, for example, extruding aluminum and cutting the size, and as shown in FIG. 3, the flat main body plate 1 and the protruding portion 2a extending at four locations on the main body plate 1 are formed. ~ 2d. For example, if it is for building materials, such as a sash, the length L of the longitudinal direction is cut | disconnected by about 300-3000 mm by the process after extrusion molding.

  As shown in FIG. 1 and FIG. 2, the shape material carrying-in device 12 is configured to load a loaded shape material W1 before processing in the Y direction (a direction perpendicular to the longitudinal direction of the shape material W1), and a loader 20. The first conveyor 22 that receives the profile W1 at the output end thereof and transfers it in the X direction (the longitudinal direction of the profile W1 or the direction extending in parallel to the longitudinal direction) toward the subsequent press working portion 14. ing.

  The press working unit 14 includes a plurality of press units 24 arranged in parallel in the X direction, and a different die 24a (punch, die, etc.) is attached to each press unit 24, and various press workings can be performed. . Here, as shown in the shape W2 after press working in FIG. 4, drilling is performed to open large-diameter holes B1 at a plurality of locations on the ridge 2c, and cutting is performed to cut off both ends B2 of the ridge 2c. Then, a cutting process for cutting off both ends and the central portion B3 of the protruding portion 2a, a protruding process of cutting the both ends and the central portion B4 of the protruding portion 2b, and the like are performed. Since the shape W1 is pressed while passing from the left side to the right side in the X direction in FIG. 1, a plurality of ridges 24a for cutting the central portion B4 are used to cut the shape material W1. The size of the part to be excised can be increased by the pressing process once. As a result, the number of molds 24a to be prepared can be reduced.

  The automatic transfer machine 16 includes a second conveyor 26 that transfers the profile W2 processed by the press processing unit 14 in the X direction, and a third conveyor that transfers the profile W2 toward the subsequent cutting processing unit 18 in the X direction. 28 and a transfer machine (not shown) for transferring the shape member W2 from the second conveyor 26 to the third conveyor 28. The third conveyor 28 includes a roller (not shown) and a cylinder that supports the roller so as to move up and down at a predetermined position. Since the shape material W2 on the second conveyor 26 is placed so as to be easily pressed, the transfer machine transfers the shape material W2 to the third conveyor 28, and the subsequent cutting portion 18 is moved. Place it so that it can be easily processed. For example, the upper surface and the lower surface of the shape member W2 are reversed. In other words, the shape W2 and the shape W2 on the second conveyor 26 have the protrusion 2a facing the lower surface side, and when the second conveyor 26 is transferred to the third conveyor 28, the protrusion 2a is the upper surface. Try to face to the side. This is because the processing at the press processing portion 14 is easier to perform when the protrusion 2a is on the lower surface side. The reason why the automatic transfer machine 16 is reversed is that the subsequent machining at the cutting unit 18 is easy to perform and the conveyance to the cutting unit 18 is easy to perform.

  As shown in FIG. 5, the cutting unit 18 includes a profile member 30 that holds the profile W2 in a predetermined position, and a profile that is movably attached to the rail 32 a and is held by the profile holder 30. The machining head 32 includes a machining head 32 that cuts W2 and a control unit (not shown) that controls the operations of the profile holding unit 30 and the machining head 32. The cutting unit 18 uses the various tools attached to the processing head 32 to perform precise cutting by numerical control. Here, as shown in the shape W3 after cutting in FIG. 6, the salami fir processing, the main body plate, in which the inner wall C1 of the hole (cylindrical hole B1 formed by pressing) of the protrusion 2c is conical. Drilling or the like that drills small-diameter holes C2 at multiple locations. In addition, a part of the portion cut by the press working unit 14 can be further cut.

  The profile holding unit 30 includes a stopper 34 and a pusher 36 for positioning the profile W2 carried in from the third conveyor 28 in the X direction, and six sets of vises 38 for holding the positioned profile W2. ing. As shown in FIG. 7, the shape member holding portion 30 is provided with a plurality of up and down rollers 40 that support the shape W2 so as to be movable in the longitudinal direction, in the feed direction of the shape W2. Each roller 40 is provided by a cylinder 42 so as to be set at a predetermined height in accordance with the thickness and cross-sectional shape of the shape member W2.

  The pusher 36 is a member that presses one end in the longitudinal direction of the shape member W2 toward the stopper 34 in the X direction according to a command from the control unit. The pusher 36 is an example, but can be attached to the processing head 32. By doing in this way, since the movement to the edge part of the shape member W2 for the press to a longitudinal direction can be performed with the motive power of the process head 32, cost reduction is possible. Although it is possible to press the stopper 34 with the power of the machining head 32, in this case, since the control of the machining head 32 becomes complicated, the direction from the end of the profile W2 toward the stopper 34 becomes complicated. In turn, it is preferable to drive by an air cylinder (not shown). Further, the pusher 36 is positioned on the extension line of the shape member W2 from the position retracted in the Y direction of the shape member W2 by an air cylinder different from the air cylinder. The stopper 34 is a member that moves in the X direction according to a command from the control unit and positions the other end of the shape member W2 pressed by the pusher 36. The six sets of vises 38 are units that are arranged at predetermined intervals in the X direction and clamp the side portions of the profile W2 positioned by the stopper 34 and the pusher 36 according to commands from the control unit. In the following, each vice is given the reference numerals 38 (1), 38 (2), 38 (3), 38 (4), 38 (5), 38 (6) in order from the side closer to the third conveyor 28. Are described separately.

  The vices 38 (1) and 38 (2) are movable vices whose positions in the X direction can be moved by commands from the control unit, and the vices 38 (3) to 38 (6) are fixed in the X direction. It is a fixed vise. The interval g0 where the fixed vices 38 (3) to 38 (6) are adjacent to each other is equal to or less than a second reference length Lk2 described later. The movable range of the movable vise 38 (2) in the X direction is a range that is not separated from the fixed vise 38 (3) by the second reference length Lk2 or more. The movable range in the X direction of the movable vise 38 (1) is a range that is not separated from the movable vise 38 (2) by the second reference length Lk2 or more. The movable range in the X direction of the stopper 34 is a range that is not separated from the movable vise 38 (1) by a first reference length Lk1 described later. 8 shows a state in which the stopper 34, the pusher 36, and the vise 38 (1) to the vice 38 (6) are retracted, and FIG. 9 shows the shape W2 positioned by the stopper 34 and the pusher 36 as the vise 38 ( 1) shows a state held by the vise 38 (6).

  Here, the first and second reference lengths Lk1 and Lk2 will be described. The first reference length Lk1 is a cantilever-like portion extending from the fixing position when the shape member W2 is fixed, and is the maximum length at which the shape member W2 can be processed with a desired accuracy. is there. If the length of the cantilevered portion is equal to or shorter than the first reference length Lk1, vibration and displacement of the shape member W2 during cutting can be suppressed to be small, and processing can be performed with high accuracy. Further, the second reference length Lk2 is the maximum length that allows the shape member W2 to be processed with a desired accuracy when both ends of the shape member W2 are fixed. If the length between both ends is fixed is equal to or shorter than the second reference length Lk2, vibration and displacement of the shape member W2 at the time of cutting can be suppressed to be small, and processing can be performed with high accuracy. The first and second reference lengths Lk1 and Lk2 are stored in the control unit.

  Next, the detailed operation of the cutting unit 18 will be described based on the flowchart of FIG.

  First, the control unit grasps the length L of the profile W2 that is a workpiece (step S11). As a method for acquiring the information on the length L, the length of the shape W1 can be easily detected by a conveyance device (not shown) that conveys the shape W1 from the shape carry-in device 12 to the automatic conveyance device 16. In addition, the operator may input the median value of the length L by computer, may input it by reading a bar code or the like, and may measure it with a sensor or the like each time the shape member W2 is loaded. .

  Next, according to the length L of the profile W2, the control unit holds the profile W2 by the X position where the stopper 34 locks the profile W2, and the movable vise 38 (1), 38 (2). The X position is determined (step S12). Then, according to a command from the control unit, the stopper 34 and the movable vise 38 (1), 38 (2) at the retracted position in FIG. 8 are moved to the X position determined in step S12 (step S13). At this time, the height position (Z position) of the stopper 34 is a position sufficiently lower than each vice 38 similarly to the retracted state. The height position (Z position) of the pusher 36 is the same as the height of the shape member W2, but is retracted in the Y direction and away from the shape member W2.

  Next, the shape member W2 is carried to a predetermined position of the height of each vise 38 of the shape member holding portion 30 (step S14), the stopper 34 is raised to the height of the shape member W2, and the pusher 36 moves in the Y direction. Then, it moves on the extension line of the shape member W2, the pusher 36 presses one end of the shape member W2, and the other end contacts the stopper 34, thereby positioning the shape member W2 (step S15).

  When the profile member W2 is positioned, each vice 38 is driven in the Y direction, and clamps the side surfaces of the profile member W2 from both sides (step S16). Then, after the stopper 34 and the pusher 36 have moved to the retracted position (step S17), the machining head 38 performs various types of cutting on the shape member W2 (step S18).

  When step S18 is completed, the clamps by the respective vices 38 are released, and the processed shape member W3 is unloaded from the cutting unit 18 by the shape material unloading device (step S19). Then, each vice 38 moves to the retracted position (step S20), and one cycle of cutting is completed.

  Next, the relationship between the X position of the stopper 34 and the movable vise 38 (1), 38 (2) and the X position of the fixed vise 38 (3) to 38 (6) determined in step S12 is shown in FIG. A detailed description will be given with reference to FIG.

  First, in the retracted state, as shown in FIG. 11, the stopper 34 is disposed such that the locking surface 34 a is at the origin position in the X direction (e0 = 0), and the movable vise 38 (1) The side surface on the side is arranged so as to be separated from the locking surface 34a by a distance h0. h0 is a value less than or equal to the first reference length Lk1. The fixed vise 38 (3) is fixed at a position where the side surface on the stopper 34 side is a distance f0 from the origin, and the movable vise 38 (2) is located between the movable vise 38 (1) and the fixed vise 38 (3). It is arranged at a predetermined position. The other fixed vises 38 (4), 38 (5), 38 (6) are fixed in order with a fixed distance g0 as described above. The clamp width (length in the X direction) of each vice 38 is constant at d0. The pusher 36 is disposed at a position sufficiently away from the outermost fixed vise 38 (6).

  The X position of the stopper 34 and the movable vise 38 (1), 38 (2) determined in step S12 varies depending on the length L of the profile W2 that is the workpiece.

  The holding state 1 in FIG. 11 represents a case where the length L is very long (L = L1). Here, the fixed vise 38 (6) functions as a main fixed vise, the movable vise 38 (1) functions as a main movable vise, and the movable vise 38 (2) and the fixed vise 38 (3) to 38 (5) assist. Work as a vice.

  The controller first determines the X position of the stopper 34 based on the length L of the profile W2. Specifically, with the shape W2 being held, the engagement of the stopper 34 from the origin so that one end of the shape W2 on the pusher 36 side protrudes outside the main fixed vise 38 (6) by a predetermined length k1. The distance e1 to the stop surface 34a is determined. k1 is a value less than or equal to the first reference length Lk1. In other words, when the X position of the stopper 34 does not move with the length L1 of the profile W2, the end of the profile W2 does not reach the fixed vise 38 (6), and the fixed vise 38 (5) is the main. Although the fixed vise is formed, the length of the main fixed vise 38 (5) protruding at this time is equal to or longer than the first reference length Lk1, and thus the stopper 34 is moved from the origin. When the X position of the stopper 34 is determined, the X position of the main movable vise 38 (1) is determined. Specifically, the main movable vise 38 (1) from the locking surface 34a of the stopper 34 so that one end of the shape member W2 on the stopper 34 side protrudes outside the main movable vise 38 (1) by a predetermined length h1. The distance h1 is determined. h1 is a value less than or equal to the first reference length Lk1, and may be the same value as h0 described above. When the X position of the main movable vise 38 (1) is determined, the X position of the auxiliary vise 38 (2) is determined. Specifically, the distance j1 between the main movable vise 38 (1) and the auxiliary vice 38 (2) is arranged at the center between the main movable vise 38 (1) and the auxiliary vice 38 (3). The interval j1 with the auxiliary vise 38 (3) is determined. j1 is a value equal to or smaller than the second reference length Lk2.

  In the holding state 1, as shown in FIG. 11, the shape member W2 has one end protruding outside the main fixed vise 38 (6) by the length k1, and the other end positioned outside the main movable vise 38 (1). It is held protruding by the length h1. The two protruding portions of the cantilevered body are firmly held because each length is equal to or shorter than the first reference length Lk1. Further, the inner portion other than the protruding portion of the shape member W2 has a gap j1 or a gap g0 by the main fixed vise 38 (6), the main movable vise 38 (1), and the auxiliary vise 38 (2) to 38 (5). Hold open. Each of the five portions fixed at both ends is securely held because each length is equal to or shorter than the second reference length Lk2. Even when the auxiliary vise 38 (2) is not arranged at the center of the main movable vise 38 (1) and the auxiliary vice 38 (3), the same effect can be obtained if the wider distance is equal to or smaller than the second reference length Lk2. Can be obtained.

  Here, the control unit is configured such that the distance h0 from the engaging surface 34a of the movable vise 38 (1) and the stopper 34, the distance f0 from the fixed vise 38 (3) to the origin, the adjacent fixed vise 38 (4), 38 ( 5) and a constant distance g0 between 38 (6) and d0 of the clamp width (length in the X direction) of each vise 38 are stored. Therefore, the control unit controls the position of the stopper 34 and the position of the main movable vise 38 (1) based on the above information stored in the control unit and the information on the shape member W2 to be processed. The main fixed vise 38 (6) is determined from the calculation result, and the stopper 34 and the main movable vise 38 (so that the projecting dimension from the main fixed vise 38 (6) is equal to or less than the first reference length Lk1. 1) and movement control.

  A holding state 2 in FIG. 11 represents a case where the length L of the shape member W2 is so short that the above holding state 1 cannot be realized (L = L2 <L1). Here, the fixed vise 38 (5) functions as a main fixed vise, the movable vise 38 (1) functions as a main movable vise, and the movable vise 38 (2) and the fixed vise 38 (3), 38 (4) are auxiliary vices. Work as. The fixed vise 38 (6) does not function substantially.

  The controller first determines the X position of the stopper 34 based on the length L of the profile W2. Specifically, the engagement of the stopper 34 from the origin so that the end of the shape W2 on the pusher 36 side protrudes by a predetermined length k2 outside the main fixed vise 38 (5) while holding the shape W2. The distance e2 to the stop surface 34a is determined. k2 is a value less than or equal to the first reference length Lk1, and may be the same value as k1 described above. When the X position of the stopper 34 is determined, the X position of the main movable vise 38 (1) is determined. Specifically, the main movable vise 38 (1) from the locking surface 34a of the stopper 34 so that one end of the shape member W2 on the stopper 34 side protrudes outside the main movable vise 38 (1) by a predetermined length h2. Determine the distance h2. h2 is a value equal to or shorter than the first reference length Lk1, and may be the same value as h0 described above. When the X position of the main movable vise 38 (1) is determined, the X position of the auxiliary vise 38 (2) is determined. Specifically, the distance j2 from the main movable vise 38 (1) so that the auxiliary vise 38 (2) is disposed at the center between the main movable vise 38 (1) and the auxiliary vice 38 (3). The interval j2 with the auxiliary vise 38 (3) is determined. J2 is a value equal to or smaller than the second reference length Lk2.

  In the holding state 2, the shape W2 is held with one end projecting by a length k2 outside the main fixed vise 38 (5) and the other end projecting by a length h2 outside the main movable vise 38 (1). Is done. The two protruding portions in the cantilever state are held firmly because the lengths of the two protruding portions are not more than the first reference length Lk1. Further, the inner portion other than the protruding portion of the shape member W2 has the interval j2 or the interval g0 by the main fixed vise 38 (5), the main movable vise 38 (1), and the auxiliary vise 38 (2) to 38 (4). Hold open. The four portions fixed at both ends are firmly held because each length is equal to or shorter than the second reference length Lk2.

  A holding state 3 in FIG. 11 represents a case where the length L of the shape member W2 is short enough to realize the holding state 2 (L = L3 <L2). Here, the fixed vise 38 (4) functions as a main fixed vise, the movable vise 38 (1) functions as a main movable vise, and the movable vise 38 (2) and the fixed vise 38 (3) function as auxiliary vices. The fixed vise 38 (5), 38 (6) does not function substantially. The flow in which the control unit determines the X positions of the stopper 34, the main movable vise 38 (1), and the auxiliary vice 38 (2) is the same as described above.

  In the holding state 3, the shape member W2 has one end projecting by a length k3 (= k1) outside the main fixed vise 38 (4) and the other end having a length h3 outside the main movable vise 38 (1). Projected and held by (= h0). The two protruding portions in the cantilever state are held firmly because the lengths of the two protruding portions are not more than the first reference length Lk1. Further, the inner portion other than the protruding portion of the shape member W2 has a gap j3 or a gap g0 by the main fixed vise 38 (4), the main movable vise 38 (1), and the auxiliary vise 38 (2), 38 (3). Hold open. The three parts fixed at both ends are firmly held because each length is equal to or shorter than the second reference length Lk2.

  A holding state 4 in FIG. 12 represents a case where the length L of the shape member W2 is short enough to realize the holding state 3 (L = L4 <L3). Here, the fixed vise 38 (3) functions as a main fixed vise, the movable vise 38 (1) functions as a main movable vise, and the movable vise 38 (2) functions as an auxiliary vise. The fixed vise 38 (4), 38 (5), 38 (6) does not function substantially. The flow in which the control unit determines the X positions of the stopper 34, the main movable vise 38 (1), and the auxiliary vice 38 (2) is the same as described above.

  In the holding state 4, the shape member W2 has one end projecting by a length k4 (= k1) outside the main fixed vise 38 (3) and the other end having a length h4 outside the main movable vise 38 (1). Projected and held by (= h0). The two protruding portions in the cantilever state are firmly held because each length is equal to or shorter than the first reference length Lk1. Further, the inner portion other than the protruding portion of the shape member W2 is held at a distance j4 by the main fixed vise 38 (3), the main movable vise 38 (1), and the auxiliary vise 38 (2). The two parts fixed at both ends are firmly held because each length is equal to or shorter than the second reference length Lk2.

  A holding state 5 in FIG. 12 represents a case where the length L of the shape member W2 is short to the extent that the above holding state 4 cannot be realized (L = L5 <L4). Here, the shape member W2 is held by two of the main movable vise 38 (1) and the movable vise 38 (2), and the other vices 38 (3) to 38 (6) do not substantially function.

  Based on the length L of the profile W2, the control unit maintains the X position of the main movable vise 38 (1) and the stopper 34 at the retracted position (e5 = 0, h5 = h0), and the movable vise 38 (2 ) X position is determined. Specifically, the main movable vise is configured such that one end of the shape W2 on the pusher 36 side protrudes by a predetermined length k5 (= k1) outside the movable vise 38 (2) while the shape W2 is held. An interval j5 between 38 (1) and the movable vise 38 (2) is determined. However, in order to simplify the structure of the drive mechanism of the movable vise 38 (2), the movable vise 38 (2) can move only within a range from the retracted position to the fixed vise 38 (3).

  In the holding state 5, the shape W2 has one end projecting by a length k5 (= k1) outside the movable vise 38 (2) and the other end having a length h5 (outside the main movable vise 38 (1). = H0) is projected and held. The two protruding portions in the cantilever state are firmly held because each length is equal to or shorter than the first reference length Lk1. Further, the inner portion other than the protruding portion of the profile W2 is held with a gap j5 by the main fixed vise 38 (3) and the main movable vise 38 (1). The portion of the dimension j5 that is fixed at both ends is firmly held because the length is equal to or shorter than the second reference length Lk2.

  The holding state 6 in FIG. 12 represents a case where the length L of the shape member W2 is short enough to realize the holding state 5 (L = L6 <L5). The shape W2 is held by the two main movable vise 38 (1) and the movable vise 38 (2) as in the holding state 5.

  Based on the length L of the profile W2, the control unit maintains the X position of the main movable vise 38 (1) and the stopper 34 at the retracted position (e6 = 0, h6 = h0), and the movable vise 38 (2 ) X position is also maintained at the retracted position. Therefore, since there is no member moved in the X direction, there are advantages that the time for movement is shortened and the burden on the drive mechanism is reduced.

  In the holding state 6, the shape member W2 has one end protruding outside the movable vise 38 (2) by a length k6 (<k5 = k1) and the other end extending outside the main movable vise 38 (1). Projected and held by h6 (= h0). The two protruding portions of the cantilevered body are held firmly because the individual lengths are not more than the first reference length Lk1. Further, the inner portion other than the protruding portion of the shape member W2 is held with a gap j6 by the movable vise 38 (2) and the main movable vise 38 (1). Since the length of the dimension j6 fixed at both ends is equal to or shorter than the second reference length Lk2, it is firmly held.

  The holding state 7 in FIG. 12 represents a case where the length L of the shape member W2 is short enough to realize the holding state 6 (L = L7 <L6). Here, the shape member W2 is held only by the main movable vise 38 (1), and the other vices 38 (2) to 38 (6) do not substantially function.

  Based on the length L of the shape member W2, the control unit maintains the X position of the main movable vise 38 (1) and the stopper 34 at the retracted position (e5 = 0, h7 = h0). Therefore, as in the holding state 6, since there is no member that moves in the X direction, there is an advantage that the time for movement is shortened and the burden on the driving mechanism is reduced.

  In the holding state 7, the shape W2 has one end protruding by a length k7 (<Lk1) on the pusher 36 side of the main movable vise 38 (1) and the other end on the stopper 34 side of the main movable vise 38 (1). And projecting by a length h7 (= h0). The two projecting portions in the cantilever state are each securely held because the length is equal to or shorter than the first reference length Lk1.

  In the description of the holding states 1 to 7 so far, both end portions of the shape member W2 are projected from the specific vise (k1 to k7> 0, h0 to h7> 0), but the end portion of the shape member W2 is specified. It may be accommodated inside without protruding from the vise 38 (k1 to k7 ≦ 0 <Lk1, h0 to h7 ≦ 0 <Lk1). However, in this case, since the portion for clamping the shape member W2 is small (the length in the X direction is short) and the clamping force may be reduced, a clamping force of a certain level or more is ensured. When the vise length d0 is very short, the end of the profile W2 is set to project (k1 to k7> 0, h0 to h7> 0) so that a predetermined clamping force can be obtained reliably. Is preferred. Further, the stopper 34 can be integrated with the movable vise 38 (1) so that h0 to h7 are always constant.

  As described above, according to the shape processing apparatus 10, the shape W2 having various lengths can be always stably held by the shape holding portion 30 including the six sets of vise 38. Cutting can be performed with high accuracy. In particular, the shape W2 has a predetermined rule (a rule in which the first reference length Lk1 and the second reference length Lk2 are set so that the length from each vice of the shape W2 is not more than a certain value). Therefore, the adjustment of the vise position is minimized, and the vice is reliably held with a constant holding strength, thereby enabling stable processing. In addition, the six sets of vises 38 have a large number of fixed vise (four sets in this embodiment), and the movable vise can be minimized (two sets in this embodiment). In addition, the control program for controlling the position of the movable vise and the stopper can be simplified.

  In addition, the profile processing apparatus 10 is provided with a press processing unit 14 in front of the cutting processing unit 18 and is connected by an automatic transfer machine 16 to perform consistent pressing and cutting on the profile W1. A line is constructed, and the process from obtaining the material (shape material W1) to obtaining the product (shape material W3) can be made efficient.

  The present invention is not limited to the above embodiment. For example, the plurality of vices in the shape member holding unit may have at least a fixed vise and a movable vice as a pair, and the movable vice may be a set. As for the auxiliary vice, if processing of a long profile is assumed, an appropriate number can be provided considering the second reference length, and whether the auxiliary vice is movable or fixed is also set appropriately It is possible. In the case of an apparatus that processes only short shapes, the auxiliary vice may be omitted.
