Next, other components of the metal piece cutting apparatus 1 will be described.
As shown in FIGS. 1 and 2 (a), the metal piece cutting device 1 is for electrically measuring the load applied to the cutting blade 92 due to friction between the cutting blade 92 and the metal piece M during cutting. The display device A may be included. The display device A is preferably provided on the support column 12 on the side where the operation handle 63 is provided. Thus, the operator can adjust the feed rate of the installation table 80 (cutting tool 90) by the operation handle 63 while visually checking the load value applied to the cutting blade 92 displayed on the display device A. As the display device A, for example, an ammeter can be used.

  Next, the metal piece cutting system 200 provided with the cooling dust collecting apparatus 110 used by being connected to the metal piece cutting apparatus 1 will be described with reference to FIGS. 1 and 5. In FIG. 5, the installation table 80 is omitted for convenience of explanation.

  The cooling dust collecting device 110 is for cooling the cutting blade 92 when cutting the metal piece M, and for collecting chips and the like near the cutting portion. And a peripheral wall sealing material 112 for storing water and chips.

  The tank 111 has a two-layer structure, a recovery hose 113 is connected to the upper layer portion, and a supply hose 114 is connected to the lower layer portion. The recovery hose 113 has one end connected to the tank 111 and the other end connected to the peripheral wall sealing material 112, and sucks air and cooling water in the vicinity of the other end, thereby collecting the cooling hose 113 in the peripheral wall sealing material 112. Water is collected along with chips. The supply hose 114 has one end connected to the tank 111 and the other end fixed near the cutting blade 92, and supplies cooling water to the cutting blade 92.

  Further, a filter (not shown) is built in the upper layer portion of the tank 111, and the chips and the like contained in the recovered cooling water are filtered by allowing the cooling water recovered by the recovery hose 113 to pass therethrough. . Then, the filtered cooling water is stored in the lower layer portion and supplied again to the cutting blade 92 from the supply hose 114. Furthermore, a plurality of moving casters 111 a are attached to the lower end of the tank 111. As such a cooling device, for example, a liquid circulating device for a drilling machine described in Japanese Patent No. 3521399 can be used.

  The peripheral wall sealing material 112 is for accumulating cooling water supplied to the cutting blade 92, and for example, a first pad 115 that surrounds the cutting blade 92 from the front side when the metal piece cutting device 1 is positioned. The second pad 116 surrounding the cutting blade 92 from the rear side is connected to surround the cutting blade 92. The peripheral wall sealing material 112 is connected to the tank 111 via a recovery hose 113.

  Further, a part of the front side and both sides of the peripheral wall sealing material 112 are covered with a plastic scattering prevention plate 119 (see FIG. 5) for preventing the scattering of cooling water and chips. The scattering prevention plate 119 is formed wider than the frame width of the peripheral wall sealing material 112 so as to protrude toward the inside of the space surrounded by the peripheral wall sealing material 112.

  When the cooling dust collecting device 110 configured in this way is installed in the metal piece cutting device 1, it supplies cooling water from the supply hose 114 of the tank 111 to the cutting blade 92 and seals the used cooling water on the peripheral wall. It accumulates inside the material 112. Then, the recovery hose 113 collects a part of the cooling water collected inside the peripheral wall sealing material 112 and the chips generated at the cut portion from the water passage 118 to the tank 111. Then, the cooling water collected in the tank 111 is filtered through a filter (not shown) built in the tank 111 and supplied again to the cutting blade 92 from the supply hose 114. The cooling dust collector 110 repeats this series of operations.

  According to such a cooling dust collecting apparatus 110, it is possible to prevent the cutting blade 92 from being heated at the time of cutting, and to suppress the generation of metal sound due to friction between the cutting blade 92 and the metal piece M. can do. Moreover, scattering of chips and the like generated from the cut portion can be prevented. In addition, the amount of cooling water used can be reduced. Further, by collecting a part of the chips or the like generated from the cut portion, it is possible to reduce the burden of the post member attaching work after the work.

  A metal piece cutting system 200 is constructed by such a cooling dust collecting device 110 and the metal piece cutting device 1.

  Next, with reference to FIG. 6 and appropriate FIGS. 1 to 5 regarding the operation and procedure for the operator to cut the metal piece M from the metal plate P using the metal piece cutting device 1 and the cooling dust collecting device 110 as described above. To explain. In the drawings to be referred to, FIGS. 6A to 6H are diagrams for explaining an operation in which an operator cuts a metal piece by a metal piece cutting system including a metal piece cutting device and a cooling dust collecting device. It is. In the following description, it is assumed that the cutting blade 92 is attached to the drive device 91 in advance.

  First, as shown in FIGS. 6 (a) and 4 (a), the operator moves the rear moving wheels from the state in which all the moving wheels 21 of the metal piece cutting apparatus 1 are in contact with the metal plate P. The support frame 10 is tilted rearward by the second arm 13b with the second arm 13b as a fulcrum 21. In this state, the second arm 13b is gripped and pushed forward, and the metal piece cutting device 1 is advanced in the direction approaching the metal piece M. Then, the auxiliary beam (contact beam) 14 of the support frame 10 is moved to a position where it contacts (externally contacts) the metal piece M. At this time, if the base frame 11 is formed in a circular shape in plan view, the metal piece M is allowed to pass while the support frame 10 is inclined so that the base frame 11 or the abutting beam 14 is not shown. Abut so that it touches. If it does in this way, the metal piece cutting device 1 can be easily transported by one worker.

  Next, as shown in FIG. 6B and FIG. 1, the worker raises the support frame 10 of the metal piece cutting device 1 and moves it to the first contact portion 71 of the contact means 70 shown in FIG. 1. The metal piece M is brought into contact. When finely adjusting the position of the support frame 10 so that the first contact portion 71 contacts the metal piece M, the support frame 10 is raised by the four moving wheels 21 (in FIG. 4A). This is done by holding and operating the first arm 13a in the phantom line state) and transferring the support frame 10. Then, the operator steps on the foot lever 25 (see FIGS. 1, 2A, and 4A) of the lifting mechanism 22 to support the support shaft 24 (FIGS. 1, 2A, and 4A). )) Is reduced so that the moving wheel 21 is separated from the metal plate P, and the support frame 10 is attached to the metal plate P by magnetizing the magnet case 31 to the metal plate P as shown in FIG. Secure to. When the position of the support frame 10 is fixed, the operator places the second contact portion 72 at a position facing the first contact portion 71 with respect to the metal piece M that contacts the first contact portion 71. Then, the metal piece M is fixed via the engaging portion 73.

  Next, as shown in FIG. 6C, the operator rotates the operation handle 63 of the metal piece cutting apparatus 1 to move the installation table 80 (cutting tool 90) along the guide member 61 in FIG. By moving in the arrow direction shown in c), that is, in the direction approaching the metal piece M, the cutting blade 92 is disposed at the cutting start position.

Next, the operator, as shown in FIG. 6 (d) and FIG. 3 (c), rotating the lifting handle 52 of the vertical movement means 50 of the metal strip cutting device 1 (see FIGS. 1 and 2) Then, the installation base 80 (cutting tool 90) is lowered along the lifting shaft 51 (see FIGS. 1 and 2), and the height position of the cutting blade 92 from the metal plate P is adjusted. In this case, the installation base 80 is lowered from the position shown in FIG. 6C to the arrow direction shown in FIG. 6D, that is, the position close to the metal plate P. In this case, by adjusting the height position so that the surface of the cutting blade 92 facing the metal plate P is close to the metal plate P as much as possible, the burden of the cutting operation after the cutting operation can be reduced. .

Next, the worker installs the cooling dust collecting apparatus 110 as shown in FIG.
First, the peripheral wall sealing material 112 is installed so as to surround the cutting blade 92. Then, the supply hose 114 of the tank 111 is connected to the drive device 91, and the recovery hose 113 is connected to the water passage 118 (see FIG. 5) provided in the peripheral wall sealing material 112.
In this state, the operator drives the drive device 91 to rotate the drive shaft 93 at a high speed, thereby rotating the cutting blade 92 at a high speed and driving the cooling dust collecting device 110.
Then, by rotating the operation handle 63, the installation base 80 and the cutting tool 90 are moved while being cut in the direction of the arrow shown in FIG. 6 (f), and the metal piece M is cut from one end side by the cutting blade 92. (See FIG. 3 (d)).

  At this time, as shown in FIG. 6G, the operator can confirm the state of the load applied to the cutting blade 92 by the value displayed on the display device A, so that the load applied to the cutting blade 92 is excessive. In order to prevent this, the rotation amount of the operation handle 63 is adjusted, and cutting is performed while adjusting the feed rate of the cutting blade 92.

  Then, the operator confirms that the installation table 80 (cutting tool 90) has come into contact with a stopper (not shown), and stops the driving device 91. In the present embodiment, the stopper (not shown) is arranged slightly closer to the front side (left side in FIG. 1) than the other end of the metal piece M. According to this, the operator stops the driving device 91 just before the cutting blade 92 of the metal piece cutting apparatus 1 cuts the other end portion of the metal piece M. This is because the metal piece M falls on the cutting blade 92 and the damage to the cutting blade 92 is prevented by cutting the metal piece M.

  6 (f) and FIG. 6 (g), the cooling dust collector 110 sprays the cooling water on the cut portion as described above, and the cooling water sprayed on the work position and A series of operations of circulating the cooling water in which the chips are collected, filtered and circulated again is repeated.

  Next, the operator releases the abutment means 70 from the metal piece M, moves the cutting blade 92 from below the metal piece M by operating the operation handle 63, and retracts, as shown in FIG. 6 (h). Then, the metal piece M is separated from the metal plate P and removed by hitting one end of the metal piece M in an uncut state with a hammer H or the like.

In this way, the metal piece M can be removed from the metal plate P.
When a part of the metal piece M remains on the metal plate P after cutting the metal piece M from the metal plate P, the metal plate can be replaced by replacing the cutting blade 92 with a grindstone (not shown). By cutting the surface of P, the metal piece M can be more reliably removed from the metal plate P.

As mentioned above, although one Embodiment of this invention was described, this invention is implemented in various forms, without being limited to the said embodiment.
In this embodiment, the guide member 61 is rotated by the operation handle 63 so that the installation table 80 is manually moved horizontally along the rotation direction of the feed screw 62. However, the present invention is not limited to this. You may make it horizontally move automatically. If the control of the motor at this time is controlled by fluctuations in the current (voltage, power) applied to the cutting blade 92, the burden on the cutting blade 92 can be reduced.

  Further, the peripheral wall sealing material 112 of the cooling dust collecting apparatus 110 may cover the lower surface portion that comes into contact with the metal plate P with a rubber mat (not shown). According to this, since the rubber mat (not shown) is interposed between the peripheral wall sealing material 112 and the metal plate P, the degree of adhesion between the peripheral wall sealing material 112 and the metal plate P can be increased. For this reason, it is possible to reliably prevent the cooling water after use from leaking out of the peripheral wall sealing material 112.

  Further, as shown in FIG. 3C, the support ring 101 (see FIGS. 1 and 2B) of the suspension arm 100 (see FIGS. 1 and 2B) and the through hole M1 of the metal piece M. As shown in FIG. 3D, the wire 102 (see FIG. 1) is passed through the wire 102 (see FIG. 1), and the cutting operation may be performed in a state where tension is applied to the wire 102 so as to lift the metal piece M upward. .

  Of course, the problem of the present invention can be solved by having only the support frame 10, the moving means 40, the fixing means 30, and the transfer means 20 of the metal piece cutting apparatus 1.

It is a general view of a metal piece cutting device and a cooling dust collecting device.
