Description

Automatic iron plate cutting machine

The present invention relates to a steel sheet automatic cutting device, and more particularly, to an automatic cutting device to automate the cutting work for the steel plate to improve the workability, and to improve the accuracy of the cutting angle to produce a good quality base material. .

In general, a large ship is composed of a plurality of ship blocks are assembled, each ship block is made by combining a plurality of base materials by mutual welding.

As such, most of the base materials constituting the ship block are coupled to each other by welding, so that the reliability of the welding serves as an important factor in determining the safety of the ship.

On the other hand, when welding the base material and the base material is to perform an improved process to be formed to be inclined at a predetermined angle the edge of the base material located in the joint portion to be welded evenly with respect to the thickness surface of the base material as a whole.

At this time, for cutting and improving the iron plate for manufacturing the base material to perform the operation using a gas torch, it will be described with reference to the accompanying FIG.

Conventional operation of cutting the iron plate with gas to obtain a cut is performed by using a gas cutting device as shown in Figure 1, the first of the circular cutting using a compass (not shown) on the iron plate to be cut Mark the point and assemble the round bar 12 of the torch fixture 11 mounted at the tip of the torch 10 to the conical center 13 to coincide with the cutting point indicated for cutting, and then the conical center ( Fix the tightening bolt (13a) on the 13) to maintain the adjusted cutting position.

Thereafter, oxygen and gas are supplied through the hose 14 from an external fuel supply source (not shown), and the oxygen and gas are blocked and supplied by the valve 15 of the torch 10.

Accordingly, the operator performs the cutting operation by opening the high pressure oxygen valve 16 provided on the torch 10 while controlling the opening to the valve 15 to oxidize the cutting point through the high pressure oxygen.

When the worker starts to move the torch 10 at the same time as the cutting operation starts, the torch 10 is rotated about the conical center 13 to cut the steel plate.

Thereafter, when the position of the torch is located at the initial starting point, when the high pressure oxygen valve 16 is locked and the valve 15 is sequentially locked, when the flame is extinguished, the cutting work for the iron plate is completed and the circular cutting material, that is, the base material Will be obtained.

On the other hand, the circular base material obtained by the cutting operation as described above by adjusting the angle of the torch 10 for the complete welding of the other structure assembled to the outer diameter to finish the improved angle cut surface is formed on the edge of the base material, The cutting operation for is completed.

However, the above-described series of working processes for cutting a conventional iron plate have the following problems.

First, since the operator performed the cutting operation while holding the torch 10 directly while the worker was in close proximity to the torch 10, there is a high risk of burn injury of the worker due to the high temperature flame and the gross scattered during the cutting operation. There was.

Secondly, since the worker grasps the torch 110 and moves by the circumferential direction along the marked cutting point of the iron plate, it is made by hand to perform the cutting operation, so that the distribution of flame discharge is uneven, and the dragline of the cutting surface after cutting line) was rough.

Accordingly, there is a problem in that work productivity is lowered because additional grinding occurs.

Third, since the cutting operation is made by hand, the angle of the improved angle cut surface formed on the outer diameter portion of the cut base material is poor, there is a disadvantage that can not produce a good base material.

Fourth, there is a problem that it is not easy to cut the thick plate (40t or more) because a separate device for the preheating operation is not provided.

The present invention is devised to solve the above problems, the object of the present invention is to improve the workability by improving the workability as well as the outer diameter cutting operation and improvement angle cutting operation of the steel sheet to produce the base material at the same time, It is to provide an automatic cutting device that can provide high quality base materials by increasing the accuracy of the angle of improvement through automation.

In addition, the rotation member is provided between the sub-torch and the flow bar. It is desirable to allow the angle of the subtorch to be adjustable.

According to the automatic cutting device according to the present invention has the following effects.

First, since the worker does not have to approach the flame during the cutting operation for the iron plate, there is an effect that a safety accident such as a burn does not occur.

Second, since the cutting operation is made automatically, since the finishing of the cutting surface is smooth and the angle of the improved angle cutting surface can be made precisely, a good base material can be produced.

In addition, since additional work such as finishing work is not required, work productivity is improved.

Third, since the cutting of the outer diameter and the angle of improvement are made at the same time in one cutting operation, the work productivity can be maximized and the manpower input can be minimized, thereby reducing the waste of manpower.

Fourth, since the sub-torch for cutting the angle of improvement also has a preheating operation, there is an effect that the thick plate can be easily cut.
