Description

Apparatus for changeing wheel of strip welder}

The present invention relates to a welder for welding a seam in the width direction so as to perform a continuous process of a strip. More specifically, a movement of a welder's wheel mounted on a seam of a strip to perform a substantial welding operation is performed. The present invention relates to a wheel replacement apparatus for a strip welder, in which a replacement of the welder's wheels is carried out by using a car, so that the operation rate of the welder can be improved.

In general, in the manufacturing process of strips, a series of continuous operations such as rolling, plating, surface treatment and processing are performed. In order to perform such a continuous process of strips, seam welding for connecting strip coils continuously is performed. The seam welding operation of such strips is usually used in the case of strips having a small width, and the seam welding of such strips is schematically shown in FIG.

That is, as shown in FIG. 1, the strip S of the coiled coil 110 unwound from the payoff reel (POR) 100 is transferred as a pinch roll 130 on the table 120, and The welding wheel 210 of the welder 200 installed at one side of the table 120 welds the seam S 'portion of the strip S to perform a continuous strip process.

On the other hand, the welder 200 as described above is shown in more detail in Figures 2 and 3, the drive shaft 222 installed in the bottom of the straddle shaft 222 between the base 220 on both sides of the base 220 The welding main body 226 moving along the central support 228 of the coupling unit 226 is moved when the screw shaft 222 is rotated, and the welding main body 226 moves left and right, vertically to both sides of the welding main body 226. The welding wheel 210 is coupled to the fixing bolt 234 through the moving block 232 installed at the lower portion of the internal air cylinder 230, and the nut 234 ′.

Therefore, in the conventional welder 200 as described above, as the welding wheel 210 moves up and down as the air cylinder 230 of the main body 236 operates, the strip S seam welding on the table 120 is performed. And, the welding wheel 210 is to adjust the lowering width by the stopper 236 installed on both sides of the main body 236.

However, in the above conventional welding machine, in particular, the welder wheel, when the seam welding of the strip is continuously performed, the welding wheel 210 is worn by the friction between the welding wheel 210 and the strip S, and thus The same welding wheel 210 should be replaced periodically, as shown in Figure 3, because the fixing bolt 234 and the nut 234 'is fixed to both sides of the main body 236, once of the welding wheel 210 When disassembling, the worker dismantles the nut 234 'in a narrow space in the state of holding the wheel 210 by hand, and the replacement of the welding wheel 210 is extremely delayed.

As a result, the stopping of the welding machine for the replacement of the welding wheel 210 is continued, which delays the seam welding of the strip and lowers the overall acidity, in particular, when the worker manually replaces the welding wheel 210, the wheel falls. There is a risk of frequent equipment damage and safety accidents caused by workers.

The present invention has been made to improve the various problems as described above, the object of the present invention is to use a mobile car equipped with a wheel of the welder that performs a substantial welding operation in contact with the seam of the strip, according to the wheel wear of the welder It is to provide a wheel replacement device for a strip welder which makes the replacement work extremely easy and improves the welding machine operation rate.

In addition, another object of the present invention, the operator does not need to tighten the operation in a narrow space on the side of the main body of the welder, such as safety accidents such as stenosis of the operator occurs when replacing the welding wheel and equipment damage due to the falling wheel To provide a wheel replacement device for a strip welder.
