Grinder in welder
[14] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a welding line for welding and connecting strips and strips for continuous operation in a stainless production process, and more particularly, to a polishing apparatus of a welder for removing spatters and welding beads generated during welding.
[15] Generally, in order to produce stainless hot rolled or cold rolled coils, a number of processes are required. At the inlet of each process, a welding line is welded to connect the front end of the preceding strip and the rear end of the trailing strip so that continuous processing of the strip can be performed. Is installed.
[16] Due to the surface damage of various rolls and the generation of roll marks due to the generation of spatters and welding beads generated in the process of welding stainless steel in such a welding line, quality and productivity are deteriorated.
[17] In addition, when the welded portion is wound, line marks applied to the strip generate a stamp mark due to the welded portion on the surface of the strip, thereby degrading the quality.
[18] In addition, the stamp marks are a cause of plate breakage when reworking the stainless coil.
[19] In order to solve this problem, conventionally, a worker removes weld beads and spatters using a polishing machine.
[20] However, a lot of work maneuver due to the manual work, there is a problem that the weld bead and spatter is not removed neatly.
[21] SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a polishing apparatus for a welder, which can remove chips and chips generated at this time while cutting the beads of the weld portion in the welder.

It includes a clamp portion consisting of.
[23] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a perspective view showing the overall structure of a welding machine equipped with a polishing apparatus according to the present invention.
[24] The present invention includes a conveying part (11) for moving the polishing part to the left and right, a polishing part () for polishing the weld bead formed in the welded portion of the preceding strip and the trailing strip, and a clamp part for fixing the preceding strip and the trailing strip.
[25] The conveying unit 11 is a fixed frame 15 which is erected by four supports 14 between the feeding table 12 and the unfeeding table 13, and the rack frame 16 installed in the middle of the fixing frame 15. And a moving frame 17 movably mounted to the rack frame 16 and a transfer motor 18 installed on the moving frame 17.
[26] Here, the guide groove 19 is formed on the front side of the rack frame 16, the guide jaw 20 corresponding to the guide groove 19 is formed inside the moving frame 17.
[27] The first pinion gear 22 meshed with the rack gear 21 of the moving frame 17 is coupled to the rotation shaft of the transfer motor 18.
[28] The polishing unit 31 includes a plurality of lifting cylinders 32 installed in a direction perpendicular to the moving frame 17, a bogie 33 fixed to the rod end of the lifting cylinder 32, and a bogie 33. It is composed of a rotating motor 34 is installed, and the body 36, which can be lifted and lowered by the rotation of the rotary motor 34, the abrasive motor 35 is mounted.
[29] The rotary motor 34 is installed on the upper surface of the trolley 33, and the second pinion gear 37 is coupled to the rotary shaft of the rotary motor 34.
[30] The rack bracket 38 engaged with the second pinion gear 37 is erected perpendicularly to the body 36.
[31] The rack bracket 38 has rack gears 39 formed on both sides thereof, and installs idle gears 40 engaged with the rack gears 39 on the trolley 33.
[32] The wheel 41 is installed at the bottom of the trolley 33 and is movable on the upper surface of the upper plate which will be described later.
[33] The body 36 is provided with a polishing motor 35, the bottom stone 42 is fixed to the rotating shaft of the polishing motor 35.
[34] In order to discharge the chip chips generated during the rotation of the bottom stone 42 to the outside, the bottom stone cover 43 is installed on the outside, the suction line 44 is connected to the bottom stone cover 43.
[35] The clamp part 31 is installed such that the leading strip S1 and the trailing strip S2 can be fixed without moving while the polishing part 31 is being polished.
[36] The clamp unit 51 is a pair of the movable cylinder 52 installed on the four support 14 of the fixed frame 15, the upper plate 53 fixed to the fixed frame 15, and the upper plate 53 It consists of a lower plate 54 which moves up and down from the lower side of the strip (S1) (S2) to support the strip.
[37] Here, the up cylinder 52a and the down sensor 52b are installed in the moving cylinder 52 to limit the operating range of the moving cylinder 52.
[38] The lower plate 54 is fixed to the rod end of the moving cylinder 52.
[39] The polishing apparatus of the welding machine according to the present invention configured as described above exhibits the following actions.
[40] The front end of the leading strip S1 and the trailing strip S2 with the movable cylinder 52 extended to secure the leading strip S1 and the trailing strip S2 with the upper plate 53 and the lower plate 54. This is followed by welding.
[41] Then, by moving the transfer motor 18 to move the moving frame 17 to the position to start polishing.
[42] Then, the raising and lowering cylinder 32 is expanded until it is detected by the lower sensing sensor 32b. Then, the wheel 41 installed on the cart 33 is seated on the upper surface of the upper plate 53.
[43] When the wheel 41 is seated, as much as the thickness of the upper plate 53, the bottom stone 42 may be lowered further to polish the weld bead. To this end, by rotating the rotary motor 34 to rotate the second pinion gear 37, the rack bracket 38 meshed with the second pinion gear 37 is lowered, so that the body 36 is also lowered together. And lower until the bottom 42 is in contact with the weld.
[44] In this state, the polishing motor 35 is operated to rotate the bottom stone 42, and the transfer motor 18 is operated to move the moving frame 17 from one side to the other side to polish the welded part.
[45] As the polishing proceeds, the diameter of the bottom stone 42 is reduced. The bottom bracket 42 is rotated by rotating the rotary motor 34 so that the bottom stone 42 and the welding bead are always uniformly contacted.
[46] And the weld bead and chip crumb generated by the bottom stone 42 is discharged to the outside through the suction line 44 in the interior of the bottom stone cover 43.
[47] When polishing is finished, the lifting cylinder 32 is raised until the upper detection sensor 32a is detected.
[48] As described above, the polishing apparatus of the welding machine according to the present invention cuts the weld bead protruding from the surface of the strip to the same height as the thickness of the strip and simultaneously discharges it to the outside using a suction line to prevent roll marks by the welding spatter. And damage to the roll surface and the strip surface by the welding bead in advance.
[49] In addition, by removing the welding bead directly by the worker using a polishing device can reduce the work maneuver to improve the work efficiency.
