Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for removing slag, spatter, scale, etc. stuck to a long piece of melted steel plate cut by gas cutting or the like.

[Conventional technology]

For melt-cut products made by cutting steel plates using the gas cutting method,
Along the cut edges on both sides of the welded product, spatters of molten iron particles, slag with adhered iron slag, and high-temperature heating during gas cutting may cause damage.
Scale, etc. consisting of an oxide film formed on the surface is fixed to the surface.

When the melt-cut product is a long plate-like product, conventionally, in order to remove the adhered material, an operator manually grinds the product using a hammer or a grinder. Of these adherents, the largest amount of slag adheres along the cut edge on the back side of the fuse-cut product, so in order to remove it manually, the long fuse-cut product must be lifted up with a magnetic crane, etc. Grinding work was done by manually grinding the back side using a machine, or by lifting one side of the fused product using a magnetic crane and turning it over.

[Problem that the invention seeks to solve]

Conventional manual grinding and removal of adhered materials on melt-cut products is inefficient, and in the case of particularly heavy long plates, the grinding work must be carried out while hoisted with a magnetic crane, etc. When the machine was turned over, there was a risk of a falling accident, which posed a safety problem.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a processing device that can efficiently and safely remove stuck objects from long melt-cut products automatically and partially manually.

[Means for solving problems]

As a result of repeated research by the present inventor to achieve the above object, it has been found that by polishing both sides of the melted product with a rotating wire brush while conveying it on a conveyor, most of the spatter on the top surface of the melted product and the scales on both sides can be removed. All of the slag can be removed, but the slag that is strongly stuck to the cutting edge on the bottom surface cannot be completely removed with a wire brush alone, so after polishing with a wire brush,
The remaining deposits such as slag can be easily and completely removed by manually grinding with a grinder, etc., and the remaining deposits after being ground with a wire brush are mainly removed along the cut edges on the back side of the melt-cut product. To avoid this, the fused product is automatically turned inside out beforehand, passed between rotating wire brushes, and then manually polished off with a grinder to remove any remaining adhered materials on the surface. The present invention was completed by discovering that it is possible to carry out a removal process.

Next, the content of the present invention will be explained in detail with reference to the drawings.

The rotating wire brushes are arranged along the top and bottom of the conveyance path of the long plate by the chain conveyor so as to slide on the long plate being conveyed. be done. The rotating wire brushes 24 are formed into a cylindrical shape by installing steel wires or the like in a radial manner, and each of the rotating wire brushes 24 is rotationally driven by a motor (not shown). The rotating wire brushes 24 and 33 are rotated so that the long plates slide in the same direction as or in the opposite direction to the conveying direction.

[Effect]

Next, the operation of the processing apparatus for melt-cut long plates of the present invention will be explained. Fused long plates made of steel plates cut by a gas cutter or the like are stacked and placed at the position 30a in FIG. 1 by a forklift or the like.

First, the hydraulic cylinder 18 is activated to rotate the rotating arm 15 to a position parallel to the connecting rod 17, and the long plate 30 is lifted up and placed on the rotating frame 13 by the carrying magnetic crane 1. place The rotating arm 15 is rotated by 90 degrees by the fluid pressure cylinder 18,
After the long plate 30 is sandwiched between the rotating frame 13 and the rotating arm 15, the rotating frame 1 is moved by the motor 10.
3 and the rotating arm 15 are rotated 180 degrees around the rotating shaft 12 to invert the long plate 30 and place it on the first stage chain conveyor 20.

Since the chain conveyor 20 is constantly operated, the elongated plate 30 is forcibly conveyed by being held between the upper and lower chain conveyors 20 of the first stage, and the rotating wire brushes 2 arranged along the upper and lower sides of the conveyance path are used.
4, both sides of the long plate 30 are polished.

The long plates are conveyed from the first stage chain conveyor 20 to the second stage.
The plate is delivered to the chain conveyor 21 in the second stage and then conveyed, and the rotating wire brush 33 in the second stage polishes the parts that could not be polished by the rotating wire brush 24 in the previous stage, and the entire sides of the long plate 30 are polished. The scale on both sides of the shaku plate and most of the spatter and slag are removed.

The long plate carried out from the second chain conveyor 21 slides on the rotating table 27 and comes into contact with the stopper 31 and stops. In this state, any adhered substances such as slag remaining on the top surface of the long plate (the surface that was the bottom surface when cutting) are manually ground off using a portable grinder or the like.

If necessary, use the rotary actuator 28.
The L-shaped arm 29 is rotated 270 degrees by the operation of
After the long plate is held between the rotating table 27 and the L-shaped arm 29, the rotating table 27 is rotated 90 degrees together with the long plate to stand the long plate vertically. If there is any adhered material remaining on the top surface of the machine, remove it by manual polishing in the same way.

Thereafter, the rotating table 27 and the L-shaped arm 29 are sequentially rotated back to their original positions. Next, the elongated plates 30 are lifted up by the magnetic crane 32 for carrying out, lowered to a predetermined position, and stacked.

If there is no need to reverse the elongated plate 30, the elongated plate 30 can be directly placed on the first stage chain conveyor 20 by the carrying magnetic crane 1.

〔Effect of the invention〕

According to the processing apparatus for a long welded plate of the present invention, the stuck substances on both sides of the cut long plate are automatically removed leaving some slag and spatter, and most of the remaining stuck substances are carried out. Since it is stuck to the top surface of the long plate, it can be easily removed manually using a grinder, etc., and the stuck material can be removed extremely efficiently and accidents can be eliminated during the removal work. There is an effect that can be achieved.
