Description

Lug cutting device

The present invention relates to a lug cutting and cutting device capable of quickly cutting and cutting a lug to a desired height of an operator by having a rotary cutting disc equipped with a plurality of inserts without a separate finishing work.

In general, when a ship is built in the shipbuilding industry, the whole ship is divided into several large blocks, and then stacked and connected to complete the ship. As such, the process of stacking and connecting blocks is mounted, and a large crane for lifting or moving blocks is necessarily used for mounting. In this case, in order to connect the hook of the crane to the block, a plurality of lugs separately manufactured are installed. The lugs described above are very useful and necessary in the mounting process, but they must be removed again when the mounting process is completed. To do this, first mark the cutting line at a predetermined position from the bottom of the welded lug and then separate oxygen. Cut along the indicated cutting line using a welding machine or the like. In addition, after the lug is cut, the remaining part is processed to have the same height as the bottom surface of the block by using a separate machine tool, and then paint is completed.

However, the above-described lug removal method takes a long time to remove one lug and also requires a skilled worker, thereby increasing the cost of the work process.

The present invention is devised to solve the conventional problems as described above, the object of the present invention is a lug cutting and cutting device that can quickly cut and cut the lug to the desired height of the operator without a separate finishing work To provide.

Hereinafter, the lug cutting and cutting device 100 formed as described above will briefly describe the operating state.

First, the lug cutting and cutting device 100 is placed in front of the lug (not shown) to be removed. When the cutting device 100 is disposed in this way, the user calculates the cutting height to adjust the height of the rotary cutting disc 192. At this time, when the second handle 172 is rotated, the operation lever 170 and the cylindrical worm 168 connected to the second handle 172 are rotated, and the rotating cylindrical worm 168 rotates the wheel 164. When the wheel wheel 164 is rotated, the screw shaft 166 connected to the worm wheel 164 rotates to transfer the cutting housing 182 connected to the moving protrusion 184, and according to the transfer of the cutting housing 182, 186, the rotary cutting disc 192 and the first rotary pulley 193 are transferred. At this time, in order to level the first rotating pulley 193 with the second rotating pulley 198, the user selectively disassembles the first rotating pulley 193 and then mounts the cutting shaft 186 again. That is, the first rotary pulley 193 is slidably transported along the spline groove 190 formed in the cutting shaft 186.

When the cutting height is determined as described above, power is applied to the cutting motor 196 to fix the magnetic plate 114 to the floor, and the second rotating pulley 198 rotates, and the rotating second rotating pulley 198 is rotated. The pulley belt 199 and the first rotary pulley 193 are rotated, and the first rotary pulley 193 rotates the cutting shaft 186 and the rotary cutting disc 192. As a result, the cutting insert 194 of the rotary cutting disc 192 cuts the lugs. On the other hand, when the rotary cutting disk 192 is rotated to perform the cutting, the compressor 154 operates the guide cylinder 148. In this case, the guide cylinder 148 operates the guide rod 149 connected to the coupling piece 147, and the guide rod 149 advances the second guide plate 145. As the second guide plate 145 moves forward as described above, the first housing 152 and the second housing 158 connected to the second guide plate 145 are advanced, and the cutting mounted on the second housing 158 is performed. The unit 180 is also advanced to cut the lug.

On the other hand, in order to move the lug cutting and cutting device 100, the power is applied to the compressor 154 again to the first moving cylinder 116a, the second moving cylinder 116b, the third moving cylinder 116c and the fourth. The moving cylinder 116d is operated. As such, when the first moving cylinder 116a, the second moving cylinder 116b, the third moving cylinder 116c and the fourth moving cylinder 116d are operated, the first cylinder rod 117a and the second cylinder rod ( 117b, the third cylinder rod 117c and the fourth cylinder rod 117d operate to lower the first roller 122a, the second roller 122b, the third roller 132a and the fourth roller 132b. Will be pushed out. As a result, the magnetic plate 114 of the moving base 110 is separated from the bottom. As such, when the moving base part 110 is separated from the bottom, the power is applied to the moving motor 124 to rotate the second sprocket 129 connected to the moving motor shaft 124a, and the second sprocket 129 rotates. Rotates a first sprocket 127 connected with the first chain 128. When the first sprocket 127 is rotated as described above, the rotating shaft 126 rotates to drive the first roller 122a and the second roller 122b connected to the rotating shaft 126 to transfer the cutting device 100. At this time, the third roller 132a and the fourth roller 132b are guided along the first roller 122a and the second roller 122b.

In addition, in order to change the direction of the cutting and cutting device 100 is moved, the user grabs the first handle 139 and rotates the turning lever 134, the fifth sprocket mounted on the turning lever 134 ( 135a) and the sixth sprocket 135b are rotated, and the fifth sprocket 135a and the sixth sprocket 135b, which are rotated, rotate the second chain 136 and the third chain 138 to rotate the second chain 136. ) And the third sprocket 133a and the fourth sprocket 133b connected to the third chain 138 are rotated. As such, when the third sprocket 133a and the fourth sprocket 133b are rotated, the third roller 132a and the fourth roller 132b are rotated, and as a result, the moving lug cutting and cutting device 100 is Will change direction.

As described above, the lug cutting and cutting device 100 according to the present invention has a rotary cutting disc 192 equipped with a plurality of cutting inserts 194, so that the operator can quickly The advantage is that the lugs can be cut to height.

In addition, the lug cutting and cutting device 100 may change the direction of the cutting device 100 being moved by the third roller 132a and the fourth roller 132b which are rotated by the operation of the turning lever 134. There is an advantage to this.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the present invention described in the utility model registration claims. I can understand that you can.
