Description

ROLLER HAMMER FOR SEPARATING STICKED STRIP COIL ON EDGE}

The present invention relates to a temper rolling method of an annealed cold rolled steel sheet, and more particularly, to an apparatus for easily removing the edge welded portion of the iron plate and the iron plate generated during the annealing operation, which is a heat treatment of the cold rolled coil.

In general, temper rolling is a work process that gives shape improvement, mechanical property improvement and roughness of plate surface after cold rolling, which is the most problem in tempering rolling coil after batch annealing. In the outer diameter of the outer diameter portion of the coil edge due to poor shape, winding and width failure, that is fusion.

The cold rolled coil is excellent in workability and annealing, which is a heat treatment process, is essential to obtain a beautiful surface and shape.

However, when the edge wave is severely generated, when the thickness or width defect of the inner diameter part and the outer diameter part occurs, and when the winding failure occurs due to a hole that is a defect of the steel plate, these coils are subjected to electrolytic cleaning. After degreasing by electrolytic debris) and then applying three-stage and four-stage vertically in a batch annealing furnace, which is a cylindrical annealing furnace, and annealing them for a long time, coils wound around 0.15 to 0.5mm thick steel plate are fused or edged Comes out bulging in the shape of a trumpet.

In particular, due to the characteristics of the cold rolling portion of the outer winding caused a failure, more fusion and plate overlap occurs.

These coils should be replaced with new rolls because they cannot loosen the leading edges, and even if the plate is not made until the temper mill, even if the plate is made, the edge plate may be torn or torn, causing scratches on the roll of the mill to produce the correct quality.

Therefore, the plate generating part and the trumpet-shaped outer winding part should be pre-worked before mailing. In general, the fusion-produced coil can be easily visually identified and drawn into the pay-off reel of the temper rolling mill as shown in FIG. In the transfer conveyor, tap the fusion part with a hammer 21 to loosen the fusion between the iron plate and the iron plate, and then lift it up with a crane and remove the fusion part by separating edge defects using a welding rod removal rod and cutting with scissors. .

After the severe part is removed, it is inserted into the pay-off reel, and then released by pressing and releasing it by using steel 22 on the upper part of the pay-off reel as shown in FIG. 1B. Use a hammer to tap the weld again.

This fusion control work requires a lot of labor, and the worker may be injured by tapping the edge 23 with the hammer 21 close to the thin coil, or may lose the balance of the body and fall. Many safety hazards are also inherent.

And the plate pressing by the steel roll 22 as shown in Figure 1b is also pressed to the fusion unoccupied portion in the middle of the iron plate can be damaged rather than deteriorate quality and does not give a hammering effect properly.

In addition, since the width of the coil is varied from 700 to 1230mm, there is no pressure hammer device suitable for the width and pressure control is not possible depending on the degree of fusion.

All these problems significantly reduce work efficiency.

The present invention is designed to ultimately solve the above-mentioned problems, and is operated by hydraulic pressure on the pay-off reel, and can be hammered in a state in which it can be adjusted according to the width of the coil to prevent breakage at the center of the coil. A hammer device is needed to maximize the effect than a direct vertical hammer, and a device capable of fully separating and controlling the left and right welds even under unbalanced coiled left and right coils is designed to improve work efficiency and restore stability. There is this.
