Description

  The present invention relates to a clamping device for a cutting device that holds a workpiece to be sequentially sent to a cutting position when the workpiece to be cut is mechanically cut at a plurality of locations, and particularly has a cross-sectional shape depending on an axial position. The present invention relates to a feed clamp device for a cutting device suitable for holding a changing workpiece.

  For example, when a long round bar is mechanically cut to an appropriate length, a rotating circular saw is moved forward and backward with respect to the round bar, cut with a saw blade when moving forward, and moved backward to move the round bar to its axis. The next cutting position is positioned in the moving area of the circular saw by moving in the direction, and continuous cutting is performed. When cutting, the workpiece is held and fixed by the clamp device so that the workpiece, which is a workpiece, does not move carelessly.

  FIG. 9 and FIG. 10 explain the schematic structure of the swing arm type circular saw cutting machine 1 for cutting a solid round bar as the workpiece W. FIG. 9 shows a plan view and FIG. 10 shows a front view. ing. The workpiece W is cut by moving the rotating circular saw 2 from the initial position indicated by the solid line in FIG. 10 to the cutting completion position indicated by the imaginary line, thereby moving the workpiece W forward and backward. Since the workpiece W is inadvertently moved from the circular saw reference position S at the time of cutting, it is inconvenient to hold the workpiece W by the main clamp means 3 and 4 directly connected to the hydraulic cylinder that advances and retreats in the horizontal and vertical directions. And fixed by being pressed. Note that the feed clamping means 5 is capable of reciprocating in the direction indicated by the arrow P in FIG. 9 for a constant-size feed operation of the workpiece W, and the direction of the circular saw reference position S with the workpiece W being clamped. The workpiece W is sent to the cutting position, moved in the direction opposite to the circular saw reference position S in the opened state, and then the workpiece W is pressed again. The clamping means 4 clamps the workpiece W during cutting.

  If the cross-sectional shape is uniform at any position, such as a round bar or shape steel, it is easy to press the workpiece W with the clamping means 3, 4, 5. However, it is difficult for the workpiece W having a non-uniform cross-sectional shape to be securely clamped at any position by the clamping means 3, 4, and 5.

  By the way, as a work having a non-uniform cross-sectional shape, there is an abandoned chemical shell that was abandoned by the former Japanese army. Japan is obligated to detoxify and dispose of this abandoned chemical shell based on the Chemical Weapons Convention. Detoxification / disposal treatment of chemical cannonballs involves high-temperature heat pyrolysis in a combustion furnace, but for efficient pyrolysis treatment, the chemical cannonballs should be sized appropriately for pyrolyzing the contained chemical agent. Need to cut. This abandoned chemical cannonball may explode as it is still filled, so it was said that mechanical cutting could not be performed. However, in recent years, it is technically necessary to reliably remove the filled glaze. As a result, the mechanical cutting process was reviewed, and the adoption of cutting processing by a cutting machine was promoted. When the abandoned chemical shell is mechanically cut, the cross-sectional shape is not uniform, and there is a risk that it is difficult to securely press the chemical shell. In particular, because it is a chemical shell and the outer shell is hardened to a high hardness, it must be cut using a carbide circular saw. May cause the position to shift. If the position of the shell is shifted at the time of cutting, the saw blade may be distorted, the blade or the carbide tip may be severely worn out or damaged, and the life may be shortened. In addition, most of the abandoned chemical shells are excavated and collected from buried pits, so deterioration and deformation due to the occurrence of red rust etc. are expected, so this kind of abandoned chemical shells can be reliably pressed and clamped Thus, the present applicant has previously proposed the cutting device clamping device described in Patent Document 1.

  The clamping device for a cutting device includes a gantry on which the workpiece is placed in a clamping device for a cutting device that holds a workpiece having a substantially circular cross section at a cutting position by a saw blade of a circular saw cutter. A receiving plate having a holding surface that intersects the mounting surface at an appropriate angle, and a workpiece placed on the gantry can be moved forwards and backwards. The moving pressure-clamping means having a pressing portion that presses against the base plate is provided.

Japanese Patent Application No. 2004-052599

  With the cutting device clamping device disclosed in Patent Document 1 described above, the object to be cut can be pressed in two places by the moving pressing means and clamped in three directions, so that it can be stably fixed. Even chemical shells with different cross-sectional shapes depending on the position in the axial direction can be securely fixed. On the other hand, in order to improve the efficiency of the thermal decomposition treatment of the abandoned chemical shell, it is necessary to cut it to an appropriate size. For this purpose, it is necessary to move the chemical shells so that they are sequentially positioned at the cutting positions. As a moving mechanism for this purpose, a mechanism similar to that provided in a conventional cutting device can be used, but a clamping device for moving a chemical cannonball with a non-uniform long cross-sectional shape in a clamped state. There are the following problems to hold the warhead.

  Fig. 11 shows the main forms of abandoned chemical shells: (a) 75mm red bullet 6, (b) 90mm red bullet 7, (c) 105mm red bullet 8, (d) 150mm red bullet 9 Is shown respectively. The warheads of each of these shells were removed in the pretreatment process to remove the glaze, but the joints 6a, 7a, 8a, 9a to which the warheads were attached differed due to the different warhead shapes. . The clamp device for moving the chemical shells holds these joints 6a, 7a, 8a, 9a, and presses a part of the clamp device against the end surface on the joints 6a, 7a, 8a, 9a side to thereby move the chemical shells. Must be pushed. In addition, there is a risk that chemical agents may remain in the shell because chemical agents may remain in the shell, but it is required to be automated without human intervention. However, it is possible to easily clamp different types of chemical shells. Necessary. In addition, since the amount of burial is substantial, it is required to reduce the time for detoxification and disposal, and it is necessary to reduce the time required for the cutting process, and it is desirable to reduce the time required for clamping the shell. . Furthermore, since abandoned chemical shells have been buried for more than 60 years, they are prone to deterioration and deformation due to corrosion. As mentioned above, the warhead is removed by the water jet when removing the glaze, but the deformed part is also deleted at that time, but all the shells cannot be made into a uniform shape, and the clamping device Now we need to keep these deformed shells. That is, there are several types of cannonballs themselves, and each has been deformed, so the clamping device must be able to cope with them.

  Therefore, the present invention is particularly suitable for holding and moving a workpiece having a different cross-sectional shape at an axial position, such as a chemical cannonball, and also quickly and reliably holding various cross-sectional shapes. It is an object of the present invention to provide a feed clamp device for a cutting device that can be used.

As a technical means for achieving the above object, a feed clamp device for a cutting apparatus according to the present invention comprises a main clamp means for holding and fixing an object to be cut at a cutting position by a saw blade of a circular saw cutting machine, In a cutting device feed clamp device for holding and moving the workpiece in connection with a moving mechanism of a cutting device that cuts the workpiece at the cutting position while sequentially moving the workpiece in the axial direction, A receiving vise for receiving the workpiece in a direction perpendicular to the axis thereof, a receiving vise base for detachably fixing the receiving vise, a pressing vise for pressing the workpiece to the receiving vise, and the pressing vice a pedestal for pressing devices to freely fix, one or provided in both one of the receiving device or pressing device, and can abut against abutment on the end face of the object to be cut, for the pressing device A vise pressing means for supporting the seat in a direction perpendicular to the axis of the workpiece, and pressing the workpiece against the receiving vise when moving forward; the receiving vise base, the pressing vise base and the vice pressing means; And a pedestal that is movable in the axial direction of the object to be cut by the moving mechanism, and sandwiches the end of the object to be cut by the receiving vise and the pressing vice, and the end surface of the object to be cut is The contact portion is contacted to position the receiving vise and the pressing vise with respect to the workpiece, and the workpiece is moved in the axial direction by the moving mechanism.

  When the end of the workpiece, which is a workpiece, is set at a position where it can be brought into contact with the receiving vise, and the vice pressing means is advanced, the end of the workpiece is moved by the pressing vice and the receiving vise. Part will be held. And if it moves with the said moving mechanism, a workpiece | work will be moved to the axial direction, and the desired cutting location of this workpiece | work can be located in a cutting position. Next, the work is clamped by the main clamping means, and the work is cut by operating the saw blade. If the said part is cut | disconnected, the clamping state by a main clamp means will be cancelled | released and a workpiece | work will be open | released. Next, the moving mechanism is operated to move the workpiece in the axial direction so that the next cutting position is positioned at the cutting position, and the cutting is performed again by pressing with the main clamp means.

  According to a second aspect of the present invention, there is provided a feed clamp device for a cutting device, wherein the receiving vise base is provided with a torso receiving vise for receiving a body portion at an intermediate position of the object to be cut, and a part of the pressing vise base. A body pressing vise is provided at a position facing the body receiving vise, and the body portion of the object to be cut is sandwiched between the body receiving vise and the body pressing vice.

  In addition to the receiving vise and the pressing vise, the body portion of the work is clamped.

  According to a third aspect of the present invention, there is provided a feed clamp device for a cutting device that supports one or both of the receiving vise and the pressing vise with an elastic means interposed between the receiving vise base and the pressing vise base, respectively. The receiving vise and the pressing vise are each urged in the direction of pressing the object to be cut by the accumulated force of the elastic means.

  Since the work is securely held by the main clamping means at the time of cutting, the holding state by the receiving vice and the press vist may be such that there is no problem in moving the work. On the other hand, when the workpiece is an abandoned chemical cannonball, it is deformed due to corrosion or the like, so that the receiving chemical cannonball can be reliably held by the freedom of the receiving vise and the pressing vise. In order to ensure this degree of freedom, an elastic means is interposed in one or both of the receiving vise and the pressing vise.

  According to a fourth aspect of the present invention, there is provided a feed clamp device for a cutting device, wherein the receiving vise base and the pressing vise base can be detachably attached to the pedestal portion.

  Regardless of the size of the workpiece, it can be securely held. In particular, there are various types of abandoned chemical shells, and it is difficult to make a small and a large one correspond to the same receiving vice and pressing vice. For this reason, the receiving vice and the pressing vice may be exchanged depending on the form of the abandoned chemical shell. At this time, the receiving vise base and the pressing vise base can be exchanged so that the receiving vise and the pressing vice suitable for the work to be held are securely supported, and the receiving vise and the pressing vice securely support the work. It can be held.

  Further, the feed clamp device for a cutting device according to the invention of claim 5 is characterized in that the object to be cut is an abandoned chemical shell.

In addition, since the receiving vise and the pressing vice are made detachable, the shape of the workpiece can be exchanged according to the size, and the range of the size of the workpiece that can be cut by the cutting machine can be widened. it can.

  Further, according to the feed clamp device for a cutting device according to the invention of claim 2, even when the end portion of the workpiece and the cutting position are in a separated state, the intermediate position of the workpiece can be held. It can be held stably. Therefore, it can move stably and can position a cutting location in a cutting position reliably.

  Further, according to the feed clamp device for a cutting device according to the invention of claim 3, since the receiving vise or the pressing vise is pressed by the elastic means to hold the workpiece, the outer shape of the workpiece is slightly different from the reference one. However, it can be reliably held. Therefore, even when the workpiece is deformed, the pressing vice and the like can be held without being exchanged, and the smoothing of the cutting process is not impaired.

  Moreover, according to the feed clamp device for a cutting device according to the invention of claim 4, when the receiving vise and the pressing vise are changed according to the size of the workpiece, the receiving vise and the pressing vice are also sized. Since the receiving vise base and the pressing vise base can be exchanged, the range of the shape and size of the work that can be cut can be widened.

  Hereinafter, based on a preferred embodiment shown in the drawings, a feed clamp device for a cutting device according to the present invention will be described in detail.

  FIGS. 1 to 4 show an embodiment in which the 105 mm scissors 8 is a workpiece W as an object to be cut, and this workpiece W is cut. FIG. 1 is a plan view, FIG. 2 and FIG. FIG. 4 is a perspective view and FIG. 4 is an AA arrow view and a BB arrow view in FIG. 1. A receiving main vise 3a and a pressing main vise 4a constituting the main clamp means 3 and 4 are arranged at a position sandwiching the circular saw reference position S, and the pressing main vise 4 is a piston-cylinder (not shown). The apparatus is capable of moving back and forth in the direction perpendicular to the axis of the workpiece W3 indicated by the arrow Q. The receiving vise 11 and the pressing vice 12 are arranged facing the joint 8a where the warhead of the 105mm red bullet 8 as the work W is joined.

This cutting machine is provided with a gantry 10 that is guided by a guide rod 10a by a moving mechanism (not shown) and is movable in the axial direction of the workpiece W. A receiving vise pedestal 13 is detachably attached to the gantry 10, and a receiving vise support member 14 is detachably attached to one end of the receiving vise pedestal 13. One end of a spring plate 15 is fixed to the receiving vise support member 14 as an elastic means, and the receiving vice 11 is fixed to the other end of the spring plate 15. A pedestal 16 for pressing vise is detachably attached to the gantry 10 and is slidable in the arrow Q direction, that is, in the direction perpendicular to the axis of the workpiece W. Thus, the workpiece W is advanced or retracted. A pressing vise support member 17 is detachably attached to one end of the pressing vise base 16. One end of a spring plate 18 as an elastic means is fixed to the pressing vise support member 17, and the pressing vice 12 is fixed to the other end of the spring plate 18. For example, as shown in FIG. 4, it is preferable to use a fixing bolt 14a, 17a or an insertion rod 36 as the detachable structure because it is easy to attach and detach and can be quickly performed. The pressing vise base 16 is connected to a piston-cylinder device (not shown), and the sliding operation is performed by this operation. Note that the receiving vise 11 and the pressing vice 12 are arranged so as to be opposed to each other as shown in FIGS. 1 and 2. An abutting portion 11a is provided at the end of the receiving vise 11 on the side that is the end portion side of the workpiece W so as to face the end surface of the workpiece W.

  The receiving vise pedestal 13 has a trunk receiving vise (not shown) at the end opposite to the end to which the receiving vise support member 14 is attached, and the pressing vise pedestal 16 has the pressing vice. A body pressing vice 20 is fixed to the end opposite to the end to which the support member 17 is attached. The cylinder receiving vise and the cylinder pressing vice 20 may be provided as necessary. As shown in FIGS. 1 and 3, the receiving vise base 13 or the trunk receiving vise and the trunk pressing vice 20 are provided at opposing positions.

  Further, a kicking device 40 including a kicking plate 41 and a piston-cylinder mechanism 42 for discharging the cut workpiece W from the cutting machine is provided. That is, when the piston-cylinder mechanism 42 is actuated, the kick-out plate 41 advances and retreats in the axial direction of the workpiece W, and by moving forward, the workpiece W is pushed out from the cutting machine and discharged.

  The operation of the embodiment in the case where the workpiece W configured as described above is the 105 mm red bullet 8 will be described below.

  The 105mm red bullet 8 is loaded as a workpiece W into a predetermined position where the receiving vice 11 of the cutting device faces, and the end surface on the side of the joint 8a faces the contact portion 11a. When a piston-cylinder device (not shown) is operated to advance the pressing vise 12, the pressing vise 12 and the receiving vise 11 hold the joint 8a of the 105 mm bullet 8. Further, an appropriate position of the body portion of the workpiece W is held by the receiving vise base 13 or the body receiving vise (not shown) and the body pressing vice 20. At this time, since the receiving vise 11 and the pressing vise 12 are supported by the spring plates 15 and 18 respectively, the workpiece W is received by the bending of the spring plates 15 and 18, the pressing vise 12, and the receiving vise base 13. Alternatively, it can be securely held by the cylinder receiving vise and the cylinder pressing vice 20. Then, when a moving mechanism (not shown) is operated to move the gantry 10 by guiding it to the guide rod 10a, the receiving vise pedestal 13 and the pressing vise pedestal 16 move, and the receiving vise 11 and the connected vice 11 Since the pressing vice 12 and the like move, the workpiece W held by them moves in the axial direction.

  When the cut portion of the workpiece W is located at the circular saw reference position S, the moving mechanism is stopped, and a piston-cylinder device (not shown) is operated to advance the main clamp means 4. Thus, the pressing main vice 4a of the main clamping means 4 presses the work W against the receiving main vice 3a, and the work W is sandwiched between the receiving main vise 3a and the pressing main vice 4a, It will be tightened. When the circular saw 2 is operated in this state, the workpiece W is cut. Next, when the main clamping means 4 is moved backward by operating a piston-cylinder device (not shown), the clamping state between the receiving main vice 3a and the pressing main vice 4a is released, and the workpiece W can be moved. It becomes. When the moving mechanism (not shown) is operated to move the gantry 10, the workpiece W moves in the axial direction, and the next cutting position to be cut can be positioned at the circular saw reference position S. Further, since the previously cut portion is pushed by the movement of the workpiece W and removed from the circular saw reference position S, it is dropped from, for example, the cutting device and sent to the next process. The main clamp means 4 is again advanced to clamp the workpiece W and cut by the circular saw 2. After the cutting, the main clamp means 4 is moved backward to move the workpiece W. In this way, by repeatedly moving and cutting the workpiece W, the workpiece W can be cut into a size suitable for the thermal decomposition treatment. Then, if the workpiece W is cut to a desired size, a piston-cylinder device (not shown) is operated to retract the pressing vise base 16, and the pressing vise 12 is detached from the end of the workpiece W. Work W is released. In this state, when the piston-cylinder mechanism 42 of the kicking device 40 is operated to advance the kicking plate 41, the end portion of the workpiece W is discharged from the cutting machine. Next, the moving mechanism is operated to move the gantry unit 10 so that the receiving vise 11 and the pressing vice 12 are positioned at positions where the workpiece W to be processed next can be clamped.

  The 105 mm red bullet 8 described above has a larger outer diameter than the 90 mm red bullet 7 and the 75 mm red bullet 6 and is longer, so that the workpiece W can be held only by the receiving vise 11 and the pressing vise 12. The long work W can be stabilized by increasing the distance between the receiving vise pedestal 13 or the cylinder receiving vise and the cylinder pressing vise 20 and the receiving vise 11 and the pressing vise 12 (not shown). It can be held, so that it can be moved stably.

  On the other hand, depending on the length and weight of the workpiece W, a structure without the receiving vise 11 and the pressing vice 12 may be used. 5 to 8 show an embodiment in which the 90 mm red bullet 7 is cut as a workpiece W, FIG. 5 is a plan view, and FIGS. 6 and 7 are views taken along arrows CC in FIG. FIG. 8 is a perspective view taken along the line DD, and FIG. 8 is a perspective view. In addition, the same code | symbol is attached | subjected about the site | part same as embodiment shown in FIGS. As shown in FIG. 5, the structure without the vices 11 and 12 as in the case of cutting the 90 mm bullet 7, without interposing the spring plates 15 and 18 and the vice support members 14 and 17, The receiving vise base 13 may be detachably attached to the receiving vise base 13 and the pressing vise 33 may be detachably attached to the pressing vise base 16. In the case of this structure, it is possible to cope with deterioration and deformation of the workpiece W by utilizing a buffering action of a piston-cylinder mechanism (not shown) for moving the pressing vise base 16 forward and backward. Further, an abutting portion 31a is provided on the end portion of the receiving vise 31 on the side of the end portion of the workpiece W so as to face the end surface of the workpiece W. That is, the receiving vise 31 is attached to the receiving vise base 13 and the pressing vise 33 is attached to the pressing vise base 16. In this case, as shown in FIGS. 6 and 7, the receiving vise 31 is attached to a position where a trunk receiving vise (not shown) is attached, and the pressing vise 33 is attached to a position where the trunk pressing vice 20 is attached, thereby shortening the length. The position where the workpiece W is held by the vices 31 and 33 is preferably close to the circular saw reference position S. Also, as shown in FIG. 8, it is desirable that these vices 31 and 33 be attached by hinge pins 35 or insertion rods 36 because they can be attached and detached easily and quickly. Further, a kicking device 40 including a kicking plate 41 and a piston-cylinder mechanism 42 for discharging the cut workpiece W from the cutting machine is provided. That is, when the piston-cylinder mechanism 42 is actuated, the kick-out plate 41 advances and retreats in the axial direction of the workpiece W, and by moving forward, the workpiece W is pushed out from the cutting machine and discharged.

  According to the feed clamp device for a cutting device according to the present invention, the workpiece can be reliably held even when the shape of the workpiece is slightly deformed due to corrosion or the like, and the receiving vise and the pressing vise can be exchanged even when the outer dimensions of the workpiece are different. This makes it possible to easily deal with these vise replacements, and this makes it possible to quickly replace these vices. It can contribute to detoxification and disposal.
