Description

  The present invention provides a metal thin plate suitable for manufacturing a plate component by continuously feeding a workpiece in which a long thin strip of an extremely thin metal plate is wound in a hoop shape at a high speed and press forming. The present invention relates to a feeding device.

  When the strip plate is pitched to the press machine and processed into a predetermined shape sequentially, it is necessary to supply the processing oil that is punching oil to guarantee the die life, and the strip plate processed by this processing oil is the processing equipment. It is attached to the surface. The effect of the adhesion is greater as the metal plate is thinner.

  As a feed mechanism for pitch feed for sequentially processing strip-like plates (workpieces) that are workpieces, a feed method, a pull method, a roll method, a grip method, and the like are commonly used. Below, these basic structures and operations will be outlined.

  The feeding method is a method in which workpieces are sequentially fed by a feeding device provided at the front stage of the press device. In this way, in the case of a flexible material such as an ultrathin plate, the material depends on the flexibility. However, it is difficult to smoothly feed them in such a manner that they are bent and overlapped, and it is troublesome because a special guide device is required.

  The pulling method is a method in which the workpiece is fed by sequentially pulling the workpiece into the pressing device by a pulling device provided at the latter stage of the pressing device. There is no problem like the system, which is convenient.

  In the roll method, the surfaces of the driving roller and the driven roller are brought into pressure contact with each other, and the workpiece is sequentially transferred by rotating the driving roller with the workpiece sandwiched therebetween. However, intermittent driving is also relatively difficult. Applying this roll method in combination with the feed method has the problems described above, and it is possible to apply it in combination with the pull method.

  The grip system is a system in which the workpiece is repeatedly held or released by the gripper, the transfer distance required in the holding state is moved, and the gripper is returned to the holding start position in the opened state. Similarly, there is a problem in applying in combination with the feeding method as described above, and it is possible to apply in combination with the pulling method.

  As described above, in addition to this, work adhesion and bending occur in the mold and in the transfer mechanism, and therefore, in the press process, the processing speed was 300 spm (shot per minute) or less. If the transfer mechanism is a roll system, it will be in a clamped state with line contact, so even if it is intermittent pitch feed, the work will be extended by submicrons.

  In view of the above-mentioned conventional problems, it is an object of the present invention to provide a sheet metal feeding device that eliminates these problems and that can perform stable feed positioning at a higher speed. Is.

  The means of the present invention for solving the above-mentioned problems is that the metal thin plate is provided in a press device that is provided on the rear stage side of the press device and continuously processes the metal thin plate to manufacture a metal thin plate part. A feeding device that feeds in, a clamper that presses and holds the thin metal plate from above and below in a fixed position, and a clamper that presses and holds the thin metal plate from above and below on the rear side of the clamper. A gripper that moves in the feed direction when the metal plate is released and moves the metal thin plate a predetermined distance and returns to a position where the metal thin plate should be held again, and jets of compressed gas to the upper and lower surfaces of the gripper. A thin metal plate that comes into contact with the gripper surface by an air flow of compressed gas supplied to the inside as the metal thin plate in the holding state is opened. A feeding device for a metallic thin plate so as to space the spatial positions.

  According to this means, when the metal sheet is processed by the press device by the forward feeding, the forward feeding is performed by the reciprocating reciprocating movement of the gripper. Since it is indispensable, it can be separated by compressed gas ejected from the gripper surface, for example, compressed air, and pitch feed can be performed at high speed.

  As described above in detail, according to the feeding device for a thin metal plate of the present invention, the pressing device is provided on the rear side of the pressing device and continuously feeds and processes the thin metal plate to manufacture a metal plate part. A feeding device for feeding a thin metal plate, wherein the feeding device presses and holds the thin metal plate from above and below at a fixed position, and a clamper that presses and holds the thin metal plate at the fixed position and the rear side of the clamper. The gripper moves in the feed direction when the clamper is released, and is released after the metal sheet is moved by a predetermined distance, and then returns to the position where the metal sheet should be held again. As the compressed gas ejection hole is provided and the metal thin plate in the holding state is opened, it comes into contact with the gripper surface by the compressed gas ejection air flow supplied under pressure. The metal sheet is to be separated into spatial positions.

  In this way, the compressed gas ejected from the gripper surface when the held thin metal plate is released in order to cause the forward feed to be performed by reciprocating reciprocating movement of the gripper according to the molding process by the forward feeding of the thin metal plate by the press device, For example, it can be simultaneously or instantaneously separated by compressed air, and pitch feed can be performed at high speed.

  As described above, according to the present invention, the practical effects are extremely remarkable, and the present invention can be applied to various pressing devices or metal sheet feeding devices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the metal sheet feeder according to the present invention will be described in detail below with reference to the drawings.
Throughout the drawings, the same parts are denoted by the same reference numerals for the sake of convenience in order to facilitate understanding.

  FIG. 1 is a schematic front view showing the overall configuration of the present invention, in which an extremely thin belt-like metal plate, for example, a winding frame 2 in which a long stainless steel plate 1 having a plate thickness of 30 μm is wound in a hoop shape is used as a motor. The stainless steel plate 1 to be fed is supported in a vertical posture on the support base 3 to be rotated and fed, and the stainless steel plate 1 to be fed is pulled into the press device 5 in a slack state without being strained.

  The press device 5 is provided with a press molding processing portion 8 including a lower die 6 and an upper punch 7, and the stainless steel plate 1 is sequentially processed by the vertical movement of the punch 7.

  On the right side of the press device 5 in the figure, a first feeding device 11 for pitch-feeding the formed strip-shaped stainless steel plate 1 and on the right side of the first feeding device 11 the stainless steel plate 1 is smoothly fed without stagnation. And a second feeding device 12 for transporting.

  The stainless steel plate 1 delivered from the second feeder 12 is taken up by the take-up device 13 in a slackened state, and is again wound in a hoop shape by a take-up device (not shown).

  FIG. 2 shows a plan view of a portion of the die 6 on the lower side of the press-molding section 8 in the press device 5. The base 15 made of steel for molds has a first die 16, a second die 17, and first and second lift devices 18, 19 and a third lift device 21 on both sides thereof, Are provided on a straight line in the horizontal direction in the figure. The stainless steel plate 1 is moved from the left side in the figure to the right arrow direction. Reference numeral 22 denotes a cylindrical guide that guides and supports the base on the upper punch 7 side and the base 15 (not shown) in the vertical direction. The top surfaces of the first die 16, the second die 17, and the substrate 15 are set to be the same surface.

  The outline of the operation of the press-molding section 8 will be described. The stainless steel plate 1 passes through the first lift device 18 at the left end and passes over the first die 16, and the second lift device 19 in the center portion. It passes through the inside of the second die 17 and passes through the inside of the third lift device 21 at the right end.

  As the stainless steel plate 1 is moved in the right direction in the figure, the punch 7 side of the base plate is lowered so that the punch dies corresponding to the dies 16 and 17 hold the stainless steel plate 1 in pressure contact with both ends in the width direction. A reference hole 25 serving as a guide is drilled, and press processing is performed by predetermined punching with reference to the position of the reference hole 25 sequentially by subsequent feeding at predetermined pitch intervals.

At the same time, the base on the punch 7 side pushes down the first, second, and third lift devices 18, 19, and 21 by a predetermined amount, and the position of the stainless steel plate 1 is lowered.
As the base on the punch 7 side rises, the first, second, and third lift devices 18, 19, and 21 are also raised. The position of the stainless steel plate 1 is lifted by raising the first, second, and third lift devices 18, 19, and 21, whereby the stainless steel plate 1 is spaced apart from the first and second dies 16 and 17 surfaces. Become position. That is, the first position is the same position.

  This is performed by the elastic biasing means in the upward direction built in the first, second, and third lift devices 18, 19, and 21, and the depression is resisted by the elastic force of the elastic biasing means. It is done.

  Regarding the shape according to the processing step of the stainless steel plate 1, referring to the enlarged view of FIG. 3, in order from the left end side in the drawing, first reference holes 25 at both ends in the width direction and second reference holes 26 at the inner side. Are formed at predetermined intervals that are accurate for each pair of states.

  Thereafter, a rectangular hole 27 that divides adjacent portions in the right direction in the figure, and various shapes for forming a required part shape between the rectangular holes 27 are sequentially punched out, and the first process as shown at the right end in the figure in the last step. The portion of the reference hole 25 is removed, and a narrow and continuous stainless steel plate strip 1-1 is formed with the second reference hole 26 left. FIG. 3 does not show details, and in practice, the first die 16 and the second die 17 are each processed into a shape as shown in the figure by a multi-step process.

  As described above, the stainless steel plate 1 and the stainless steel plate strip 1-1 are forced from the surfaces of the first and second dies 16, 17 by the first, second, and third lift devices 18, 19, and 21. By being in the raised spatial position, it is possible to reliably perform forward feeding easily.

  That is, in this way, the first and second lift devices 18 and 19 are disposed before and after the first die 16, and the second and third lift devices 19 and 21 are disposed before and after the second die 17. This makes it possible to do the above.

  Only one piece portion of the stainless steel plate strip 1-1 is shown in FIG. 4A, and the metal plate component 28 is shown in FIG. That is, the metal plate part is aligned with a frame (not shown) with a jig or the like and attached by welding or the like with reference to the second reference hole 26 in FIG. It becomes possible to attach both to the exact position by cutting | disconnecting.

  The first, second, and third lift devices 18, 19, and 21 will be described with reference to FIGS. 5, 6, and 7. Since the first and second lift devices 18, 19 have the same configuration, Reference numeral 18 is representatively used. The basic structure of the third lift device 21 is the same, and the first and second lift devices 18 and 19 can support the width of the stainless steel plate 1, whereas the third lift device 21 is supported by the third lift device 21. Since the device 21 is different in that the opposing widths are different so that the width of the stainless steel strip 1-1 can be supported, the description of the third lift device 21 is omitted, and is understood as such. I want.

  5A and 5B show the lift device main body 31. FIG. 5A is a plan view, FIG. 5B is a front view taken along the line A-A in FIG. Show. Since the pair of lift device main bodies 31 have the same configuration and are arranged opposite to each other, the same portions are denoted by the same reference numerals.

  The main body 32 is in the form of a block made of a steel material, and is provided with protrusions 33 and 34 extending in the vertical direction on the front and rear sides thereof, and between the protrusions 33 and 34, the upper surface is close to the left and right. Ball bearings 35, which are small and precise rollers, are fitted on the support shafts 36 in a straight line, and are prevented from coming off by the flange portions 37 of the support shafts. The support shaft 36 passes through the main body 32 and is locked by an E-shaped retaining ring 38 on the rear surface.

  A step portion 41 is formed on the upper portion of the main body 32 so as to be slightly lower than the upper surface of the roller 35, and an upper surface plate 43 with a guide surface 42 protruding so as to contact the step portion 41 is a screw 44. It is fixed by mounting.

  With such a configuration, a minute gap 45 is formed between the guide surface 42 and the upper surface around the outer ring of the ball bearing 35 as a roller, which is sufficient to allow the stainless steel plates 1 and 1-1 to pass sufficiently. Similarly, the interval between the standing surfaces 46 of the opposed step portions 41 is set to an interval sufficient to allow the stainless steel plates 1 and 1-1 to pass through.

Inclined surfaces 47 extending in a plan view are formed at the left and right ends of the step portion 41 of the main body 32, and consideration is given so as not to affect the passage of the stainless steel plates 1 and 1-1.
Moreover, the edge part of the left-right direction of the upper surface board 43 is formed shorter than the main body 32, and consideration is given so that the protrusion 34 may protrude also about the rear surface side.

  In the first and second lift devices 18 and 19, the opposing portion between the roller 35 and the guide surface 42 can pass through the continuous portion of the first reference hole 25 of the stainless steel plate 1. In the apparatus 21, the continuous part of the second reference hole 26 of the stainless steel plate strip 1-1 can be passed.

  Accordingly, the stainless steel plate 1 or the stainless steel plate strip 1-1 passing through the space comes into contact with the outer ring peripheral surface of the ball bearing 35 that is a roller, and is in a state of being supported by the rotating roller and without being in close contact with the minimum. The contact resistance ensures very reliable and stable movement. The upper guide surface 42 prevents the stainless steel plates 1, 1-1 from jumping up due to vibration or the like.

  6 is a cross-sectional view of the lift device 18 corresponding to the view (b) of FIG. 5, in which the base 15 has a laminated structure, and each of them is positioned and connected by an accurate alignment means. It is integrated.

A rectangular hole 51 is formed in the upper first base 15-1, and the main body 32 is precisely fitted in the rectangular hole 51 so that it can move in the vertical direction.
The contact of the main body 32 is only on the surfaces of the protrusions 33 and 34 and both end surfaces in the left-right direction, and the contact resistance is minimized. Further, a groove 52 having a width slightly wider than the width of the stainless steel plates 1, 1-1 is formed on the upper surface in the left-right direction in the drawing, and a passage for the stainless steel plate is secured.

  A circular through hole 53 is formed in two places on the second intermediate base 15-2, a cylindrical shaft 54 is fitted, and a screw 56 penetrating the shaft 54 via a washer 55 below the shaft 54. As a result, the moving distance in the vertical direction of the main body 32 is regulated by screwing the tip end of the screw 56 into the screw hole on the bottom surface of the main body 32.

  Since the length of the shaft 54 is longer than the thickness of the second base 15-2 by a predetermined amount, the shaft 54 can move in the vertical direction by the longer length.

  The lower third base 15-3 is formed with a through hole 57 concentric with the center of the washer 55, and a female screw 58 formed at the lower end thereof. The end face is blocked. A compression coil spring 61 is fitted in advance in the through hole 57 as an elastic means, and is elastically biased in a compressed state in contact with the upper surface of the screw plug 59 and the lower end surface of the washer 55.

  With this compression coil spring 61 as an elastic biasing means, the washer 55 is positioned in pressure contact with the lower surface of the second base 15-2, and the main body 32, that is, the lift device 18 is set at the uppermost position. The lift device 18 can move to a position where the lower surface of the main body 32 is in contact with the upper surface of the second base 15-2 by pressing the upper side with an urging force or more, and immediately by elasticity by removing the pressing force. Restored to the illustrated position.

  The stainless steel plates 1, 1-1 are shown in a two-dot chain line so as to be in contact with the upper end surface of the roller 35, and are secured at a position slightly raised from the upper surface of the base 15. Well shown. That is, this state is nothing but the same as the upper surfaces of the first and second dies 16 and 17.

  FIG. 7 is a side sectional view in the state of FIG. 6, and a pair of lift devices 18 are opposed to each other. Similarly, the stainless steel plates 1, 1-1 shown at two-dot chain lines are also at the highest position. , At a position raised above the upper surface of the base 15.

  When the punch-side base is lowered in the press working step, the punch-side reference pin is fitted and positioned in the reference hole 25 of the stainless steel plate 1, and the stainless steel plate 1 is pressed against the surfaces of the die and the punch. The lift device 18 is pushed down to the position indicated by the state 8, and predetermined processing is performed.

  8 is a position where the compression coil spring 61 is compressed when the main body 32 and the upper surface plate 43 are pressed down, and the lower end surface of the main body 32 approaches the upper surface of the second base 15-2. As a result, the stainless steel plates 1, 1-1 come into contact with the guide surface 42, and the position thereof coincides with the upper surface of the base 15 or slightly enters the groove 52. However, there is no influence of resistance or deformation on the pressure between the die and the punch.

  As press working is completed and the base on the punch side rises in accordance with the movement to the next process, the press contact of the stainless steel plates 1 and 1-1 is released, and the lift device 18 also rises to the position shown in FIG. To do. The stainless steel plates 1, 1-1 are instantaneously reliably lifted and separated without being in close contact with the die surface by the upper surface of the roller 35. Such a thing is reliably performed because the lift devices 18, 19, and 21 are provided at the front and rear positions close to both sides of the die 6 as shown in FIG. It can be performed at high speed and accurately.

  FIG. 9 is a schematic front view of the first feeding device 11 that conveys the stainless steel plates 1 and 1-1 as work materials at a predetermined pitch interval. As described above, the pressing device shown in FIG. 5 is provided adjacent.

  A clamper 66 is provided on the left side of the figure along the substrate 65, and a gripper 67 is provided at the center, and a drive mechanism unit and setting operation unit 68 for various operations are provided below. By operating the operation unit 68, for example, the pitch feed distance can be set precisely.

Further, the detailed mechanism and structure of the feed are not described here, but this device is manufactured by Sankyo Seisakusho Co., Ltd. and is well known.
The clamper 66 has a function of fixing the work piece in a stationary position and capable of opening it movably, and a gripper 67 works in conjunction with the clamper 66 to hold the work piece in a fixed and accurate distance. It is movable and has a function of repeatedly reciprocating in the horizontal direction in the figure as an open state. Such an operation function is configured to be accurately interlocked with the processing operation of the press device.

  The structure of the clamper 66 and the gripper 67 is the same for the functional part that holds the workpiece. As described above, the position of the clamper 66 is fixed, whereas the position of the gripper 67 is repeated. It differs in reciprocating motion. This common part will be described with reference to FIG. 10. FIG. 10 (a) is a front view, and FIG. 10 (b) is a side view.

  An S-shaped buffer member 72 is attached to the upper arm 71 with a screw 73, and an upper plate 74 is attached to the lower side with a screw 75, and a lower plate is placed on the upper side of the lower arm 76. 77 is attached with screws 78. The upper plate 74 and the lower plate 77 are set so as to face each other.

  The upper arm 71 does not move up and down and is fixed in position, and the lower arm 76 moves up and down so that the lower plate 77 approaches and separates from the upper plate 74. . At this time, the S-type buffer member 72 made of high-stiffness special steel relaxes the impact force when the lower plate 77 approaches, and the stainless steel plates 1 and 1 which are workpieces disposed and transferred therebetween. It functions to prevent adverse effects such as compressing and deforming -1.

  The operational relationship between the clamper 66 and the gripper 67 will be described with reference to FIG. In FIG. 11, for the sake of convenience, the upper plate including the upper arm 71, the S-type buffer member 72, and the upper plate 74 is simply shown as an upper plate. The clamper 66 side is indicated by reference numeral 66-1, and the gripper 67 side is indicated by reference numeral 67-1.

  Further, the lower plate including the lower arm 76 and the lower plate 77 is simply referred to as a lower plate, the clamper 66 side is indicated by reference numeral 66-2, and the gripper 67 side is indicated by reference numeral 67-2. .

  First, in the state of FIG. 1A, the lower plate 66-2 of the clamper is raised and the stainless steel plate 1-1 is pressed and fixed between the upper plate 66-1. The gripper 67 is located at the left end position, and the lower plate 67-2 is lifted to press and fix the stainless steel plate 1-1 with the upper plate 67-1. In this state, a slight space (gap) is provided between the lower surface of the stainless steel plate strip 1-1 and the upper surface of the substrate 65.

  Next, in the state of FIG. (B), the lower plate 66-2 of the clamper is lowered and separated from the upper plate 66-1, and the stainless steel plate strip 1-1 is opened. In this state, the gripper 67 is It moves a predetermined distance (pitch) in the direction of the arrow on the right side of the drawing while holding the stainless steel strip 1-1. That is, the stainless steel plate strip 1-1 is transported and moved.

At the position where the gripper 67 is moved by a predetermined distance, the lower plate 66-2 of the clamper is raised and the stainless steel plate strip 1-1 is sandwiched and fixed between the upper plate 66-1 and the stainless steel plate strip 1- The position of 1 is fixed. At the same time, the lower plate 67-2 of the gripper is lowered and separated from the upper plate 67-1 to open the stainless steel strip 1-1, and as shown in FIG. To return to the position shown in FIG.
Thus, during the process of fixing the position of the stainless steel plate 1-1 by the clamper 66 and restoring the gripper 67, the punch 7 side of the press device is lowered and the press working process is performed as described above.

  Further, depending on the pitch feeding process of the stainless steel plate 1 due to the rise of the punch 7 side and the completion of the press working process, the stainless steel plate 1 is lifted by the lifting devices 18, 19, 21 and lifted from the die 6 surface. Since the pitch feeding by the first feeding device 11 is performed as described above, the stainless steel plate 1 can be moved instantaneously without any problem.

  However, according to the purpose of the invention, it is necessary to shorten the time for conveyance and release by the gripper 67 according to the processing at a higher speed. It has been found that it is necessary to instantly and reliably open the flexible stainless steel strip 1-1 with an extremely thin plate to be adhered or adhered. Therefore, we decided to take measures as detailed below.

It is blocked by an adhesive material or a stopper 107. Therefore, the space from the screw hole 102 to the air ejection hole 96 is a closed and closed space.

  FIG. 14 shows a state in which the upper plate 81 and the lower plate 95 face each other so as to be in a vertical relationship. That is, as a state in which the positions of the AA lines in FIG. 12 and FIG. 13 are matched, FIG. 12 (a) is a plan view, FIG. 12 (b) is a front view, FIG. Each is shown as an arrow sectional view.

The positions of both counterbore holes 85 and 99 coincide, and the positions of the concave grooves 83 and 97 and the air ejection holes 82 and 96 also coincide with each other in the opposing positional relationship.
However, the screw hole 86 formed in the side surface of the upper plate 81 and the screw hole 102 formed in the protruding step portion 101 of the lower plate 95 have different positions, and the directions thereof are also different. It is well understood that the positions are set so as not to interfere with each other so that they do not coincide at all even if the directions differ by 90 °.

  FIG. 15 shows a state in which the upper plate 74 and the lower plate 77 of the gripper 67 shown in FIG. 10 are replaced with the upper plate 81 and the lower plate 95 in the state shown in FIG. .

At the same time as the upper and lower plates 81 and 95 start to be separated so that the gripper 67 opens the stainless steel plate strip 1-1, the compressed air ejected from the air ejection holes 82 and 96 moves from the vertical direction to the intermediate space portion. And the stainless steel plate strip 1-1 are pushed instantaneously.

  The stainless steel strip 1-1 is sandwiched between the continuous portions in which the second reference holes 26 are formed, but the central portion may be in contact with the surfaces of the upper and lower plates 81, 95 by the concave grooves 83, 97. Therefore, it is considered that there is no problem by separating only the continuous part even though it is opened.

  Compressed air is pressurized and supplied to the inside of the guide hole so that it can always be ejected from the air ejection holes 82 and 96, but the ejection hole is sealed while the gripper 67 is sandwiching and pressing the stainless steel plate 1-1. It is not ejected by being performed, but it is ejected immediately according to the process of separating and releasing.

  The air ejecting means is not provided on the clamper 66 side, but it can be arbitrarily applied if necessary. However, depending on the pitch feed by the gripper 67, the pulling force of the gripper 67 acts, so even if it sticks to the surface of the clamper 66, the gripper 67 is moved immediately, so it is not always necessary.

  FIGS. 16A and 16B are external views of the second feeding device 12 of the present invention, and are shown in a plan view and a front view in FIG. FIG. 17 shows an enlarged view of the main part of FIG. 16, FIG. 17A shows a state where the upper guide plate is removed, and FIG. 17B shows a sectional view.

  The second feeding device 12 includes an upper guide plate 111 and a lower guide plate 112 that form a rectangular rectangle. A screw insertion hole 113 is formed at an important point, and the screw insertion hole 113 is fastened with a screw. While being fixed and integrated, it is also attached to the surface of the substrate 65.

  The upper guide plate 111 is a flat plate, but is formed with a screw insertion hole 113 and an inclined surface 114 having an extension at the center of both end portions thereof.

  The lower guide plate 112 is formed with a guide groove 115 having a rectangular cross section extending in the length direction in the center portion on the upper surface side of a flat plate, and the left end in the drawing is a tapered slope whose both side surfaces expand in the opening direction. A surface 116 and an inclined surface 117 extending in the lower surface direction are formed. The inclined surface 117 is also provided on the right end side in the figure.

  On the opening side of the tapered engaging inclined surface 116, two grooves 118 are provided on both sides, and ends of a pair of air supply pipes 119, for example, flexible vinyl chloride tubes, are provided in the grooves 118. Fit into each. The depth of the concave groove 118 is slightly shallower than the outer diameter of the air pipe. Thus, the adjacent facing distance between the pair of air supply pipes 119 is equal to or slightly wider than the width of the guide groove 115.

  A guide wire 121 as a protrusion made of a hard metal thin wire, for example, a piano wire or a stainless steel wire is attached to the bottom surface in the guide groove 115 at a position slightly intruded from both side surfaces. . This attachment method is formed by repeatedly forming through holes 122 penetrating through the bottom surface, inserting guide wires 121 therethrough, and drawing out again from the through holes 122 through the groove 123 on the back surface. The Both end portions are bent and terminated in the groove 123 on the back side. Special consideration is given so that the guide wire 121 does not wave or bend in the guide groove 115. Incidentally, the wire diameter of the guide wire 121 is 0.3 to 0.4 mm.

  In FIG. 16A, the guide line 121 is indicated by a dotted line only within the guide groove 115, and the back side is not illustrated by a dotted line.

  Although it is the above structures, the width | variety of the guide groove 115 is suitably slightly wider than the width | variety of the stainless steel plate strip 1-1, and the position of a pair of guide wire 121 is the 2nd reference | standard hole of the stainless steel plate strip 1-1. It is made to correspond to the continuous part to the length direction in which 26 was formed. Further, the depth of the guide groove 115 is appropriately set deeper than the value obtained by adding the guide wire 121 to the thickness of the stainless steel plate strip 1-1.

  By combining and coupling the upper guide plate 111 and the lower guide plate 112, the guide groove 115 is hermetically sealed to form a flat guide, and the air supply pipe 119 is positioned by being pressed between the upper and lower guide plates. The

  In addition, since the upper and lower guide plates 111 and 112 are made of a hard and transparent vinyl chloride plate, the guide groove 115, that is, the inside of the guide can be visually recognized, and the internal state can be confirmed.

  FIG. 17 is an enlarged view showing only the left end portion of FIG. 16 for easier understanding. FIG. 17A is a plan view with the upper guide plate 111 removed, and FIG. ) In AA arrow sectional view. The inner end portion of the concave groove 118 that accommodates the air supply tube 119 forms a semicircular shape 124 and is opened without closing the opening end of the air supply tube 119.

  The compressed air delivered from the open end is supplied to the tapered inclined surface 116 from the semicircular portion 124 by supplying pressurized air to the air supply pipes 119 on both sides with a clean compressed gas from which dust or the like is removed, for example, compressed air. As a result, the gas flows into a guide groove 115 blocked by the upper guide plate 111, that is, a space serving as a guide, and a rapid flow is generated in the guide from the left side to the right side in the figure.

  FIG. 18 is a plan view of a state in which the upper guide plate 111 is removed from FIG. A cross-sectional view is shown in FIG. It should be noted that in the drawing (b), the right side is the upper side and the left side is the lower side.

  As well shown in FIG. 1A, the guide groove 115 is a flat guide by the upper and lower guide plates 111 and 112, and the stainless steel plate strip 1-1 in the guide groove 115 contacts the guide wire 121. Although it seems to be supported, it is actually moved so as to be lifted or contacted by the air current. In addition, since a large number of processed holes are punched and the airflow is brought into contact with the end surfaces of the holes so as to be pushed in the transfer direction, the holes can be smoothly flowed without wobbling or meandering.

  Since the position of the guide wire 121 which is a protrusion seems to contact the continuous part in the length direction on both sides of the stainless steel plate 1-1, there is no problem of being caught. In this embodiment, the guide wire 121 is formed in a zigzag shape in the vertical direction. However, a protrusion having the same function as the guide plate 112 itself is continuously formed integrally in the length direction with a cross section of a triangle shape or a mountain shape. It may be. It is also possible to provide the guide plate 111 as required.

  The metal plate component 28 in the present embodiment is an MR head suspension component for a hard disk drive (HDD). However, according to the present invention, the present invention is not limited to such a component, but various metal thin plate components. It goes without saying that it is applicable to the above.

  Metal materials can also be applied to metal thin plates other than stainless steel plates and alloy thin plates, and the thickness is not limited to thin materials other than 30 μm. The processing shape can be applied to any shape.

  By applying the present invention, a processing speed of about 300 spm can be achieved at a high speed of about 500 spm, but it is considered that it can be further increased.
