JPS63180457A - Welding burr removing device - Google Patents

Abstract

PURPOSE:To efficiently remove the welding burrs formed at a seam part in a short time and eliminate the quality disorder and improve yield by arranging polishing machines above and below a strip and moving said machines in reciprocation along the welding seam of a strip coil. CONSTITUTION:Columns 3 and 4 are erected at the both edges of a base 2, and the upper edge parts are connected by a transverse member 5. Screw shafts 6 and 7 are laid between the columns 3 and 4, and the screw shaft 6 is turning- driven by a reversible revolution motor 9, and at the same time, also the screw shaft 7 is turned together with a shaft 8 by the upper and lower bevel gears. Female screw sliders 11 and 12 are engaged with the screw shafts 6 and 7, and polishing members 13 and 14 are installed onto the sliders. Grinding wheels 15 and 16 are revolved through a belt, and attached onto the welding part of a strip S by a proper pressing force by balance weights 17 and 18. Therefore, the welding burrs on the upper and lower surfaces of the strip S can be removed efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deburring device for a strip coil seam weld.

[Prior Art] When high-carbon cold-rolled coils are connected by a narrow-wrap weld, cracks occur at the weld joint.

This spall will cause flaws on the process line roll, and secondarily will cause surface flaws on the cold rolled steel sheet. There, a worker was removing the debris using a hand grinder.

[Problems to be solved by the invention] However, in this case, it is almost impossible to remove the pars on the back side due to the structure and safety of the line, and it takes a considerable amount of time just to remove the pars on the front side. Ta.

It is an object of the present invention to provide a welding deburring device that can solve the above-mentioned problems.

[Means and operations for solving the problems] The weld deburring device of the present invention includes polishers that are driven reciprocatingly along the seam weld line of the strip coil and are disposed above and below the strip.

By moving Ig grinders placed above and below the strip along the weld seam, the welding spots on the top and bottom of the strip are simultaneously removed.

[Embodiment] An embodiment of the device of the present invention will be described with reference to FIG. In the figure, reference numeral 1 denotes a frame provided perpendicularly to the running direction of the strip S, and is constructed by standing pillars 3 and 4 at both ends of a base 2 and connecting their upper ends with a cross member 5. ing. A screw shaft 6.7 is installed above and below between the pillars 3.4. The screw shaft 6 is rotationally driven by a reversible rotary motor 9, and at the same time, the screw shaft 7 is also rotated synchronously by a shaft 8 and bevel gears provided above and below the shaft. Internally threaded sliders 11.12 engage these threaded shafts 6.7. Polishers 13, 14 are respectively attached to these sliders 11, 12 so as to be able to slide through a slight angle. These grinders 13, 14 each rotate a grinding wheel 15, 16 via a belt. The grinding wheels 15, 16 are brought into contact with the welded portion of the strip S with a suitable pressing force by means of balance weights 17, 18 respectively provided on the grinders 13, 14.

The apparatus is then placed on the exit side of the welding machine and the strip is moved to position the seam weld line at the polisher. By rotating the grinding wheels 15, 16 of the grinding machine 13, 14 and moving the grinding machine so that the grinding wheels 15, 16 are brought into contact with the weld burrs, the weld burrs on the upper and lower surfaces of the strip can be removed at the same time.

Note that the type of polishing machine is not limited to the belt-driven type. The grinding wheel may also be a brush containing an abrasive. Further, the reciprocating drive for polishing is not limited to the mechanical type, but may also be a hydraulic or pneumatic type.

Further, welding flashes can also be removed while transporting the welded strip S in the following manner.

A frame 1 provided perpendicular to the running direction of the strip S
is provided so as to be able to move at a variable speed in the running direction of the strip, and the moving speed of the frame 1 and the feed speed of the polishing machine moving in a direction perpendicular to this are adjusted in accordance with the transporting speed of the strip S. By setting this, it is possible to remove welding flashes while transporting the strip.

[Effect of the invention] The welding deburring device of the present invention is as described above,
Efficiently eliminates welding spots that occur at strip coil joints.
Can be removed in a short time.

In this way, the operating rate can be improved, quality defects caused by welding flashes can be eliminated, and yield can be improved.
