Description

A steel coil inner ring defect cutting gun

technical field

The utility model belongs to the field of flame cutting tools, in particular to a steel coil inner ring defect cutting gun.

Background technique

After the steel coil is offline, it goes through several processes such as sampling inspection, packaging, warehouse delivery and finished product output under normal circumstances. However, during the rolling process, due to equipment failure, operation and other reasons, the steel coil has many defects such as tower shape, folding, overflowing and scratching. In order to revive these quality-defective steel coils into finished coils that meet the quality requirements, they need to be divided into coils and processed manually.

When the steel coil head has defects such as tower shape and folding, it needs to be cut with a cutting gun. However, since the maximum inner diameter of the steel coil is only 762MM, and the maximum width of the steel coil is nearly 2000MM, when using traditional cutting tools to cut and deal with defects, the space inside the steel coil is narrow, which is very difficult to work. The body also needs to probe into the steel coil for cutting operations, which is very prone to safety accidents such as scalding and burns, and it is easy to cut the next layer of steel plate, which increases the loss of the steel coil. The cutting operation is very slow, greatly reducing the efficiency of processing defective rolls. so. In order to ensure safety, avoid cutting steel coils, speed up the processing of defects, and improve the recovery efficiency of steel coils, it will become particularly important.

SUMMARY OF THE INVENTION

The utility model aims to provide a steel coil inner ring defect cutting gun which can avoid cutting damage to the steel coil, speed up the processing of defects, improve the yield of the steel coil and ensure safe operation.

For this reason, the technical solution adopted by the present utility model is:

A steel coil inner ring defect cutting gun includes a gun handle, a cutting head, an acetylene gas pipe, an air pipe, a mixing chamber and a control knob. A cutting head is installed obliquely at the front end of the cavity.

The included angle between the cutting head and the horizontal plane is 10°˜20°.

The beneficial effects of the present utility model are:

1. Due to the use of the original gun handle and control knob, the stability and safety of operation when dealing with defective steel coil cutting operations are guaranteed;

2. The obliquely installed cutting head can directly see the part to be cut, which speeds up the cutting speed and improves the efficiency of processing defective rolls.

3. The operator does not need to put his head and body into the steel coil to work, which avoids the danger of being scalded and burned, and ensures the safety of the operator.

4. The modified cutting gun is flexible and convenient to operate and easy to control, which can avoid the risk of cutting the next layer of steel coils and reduce the loss of steel coils.

Description of drawings

Figure 1 is a schematic diagram of the structure of the inner ring defect cutting gun of the steel coil.

In the picture: gun handle 1, control knob 2, acetylene gas pipe 3, air pipe 4, mixing chamber 5, cutting head 6.

Detailed ways

As can be seen from Figure 1, the inner ring defect cutting gun of the steel coil includes a gun handle 1, a control knob 2, an acetylene gas pipe 3, an air pipe 4, a mixing chamber 5 and a cutting head 6. First, the utility model changes the acetylene gas pipe 3 and the air pipe 4 from straight pipes to curved pipes, that is, the acetylene gas pipe 3 is bent into a right-angle bend, and the air pipe 4 is bent into two right-angle bends, and then connected to the horizontal on the mixing chamber. The second is to install the cutting head 6 at the front end of the mixing chamber 5, which is perpendicular to the horizontal plane, at an angle of 15° to the horizontal plane.

In the past, when cutting the internal defects of the steel coil, it was very difficult to cut the internal defects of the steel coil due to the small space inside the steel coil when using the original tool, and it was easy to cut the bottom steel plate of the steel coil. Burn the cutting personnel. By using the utility model, the appeal defect is overcome, the cutting is simple and easy, the time for cutting the defect is greatly shortened, not only the cutting efficiency is improved, but also the personal safety is ensured.

Claims (2)

1. The utility model provides a coil of strip inner circle defect cutting torch, includes gun handle, cutting head, acetylene gas pipe, air hose, hybrid chamber and control knob, its characterized in that, has the acetylene gas pipe and the air hose of quarter bend to connect respectively on horizontal hybrid chamber, and the cutting head is installed in hybrid chamber front end slope.

2. The steel coil inner ring defect cutting gun according to claim 1, wherein an included angle between the cutting head and a horizontal plane is 10-20 °.
