Description

[Detailed Description of the Invention] This invention relates to an automatic fusing machine for fusing and cutting materials such as steel plates into predetermined shapes.

As is well known, fusing cutting of steel plates, etc. is a cutting method that is often used when the material is thick and the area of the product to be obtained is large, but fusing cutting takes more time than other cutting methods. In addition, due to the poor working environment, automatic fusing machines using numerical control (NC) have recently come into use.

By the way, fusing work requires that the material be relatively large and heavy as mentioned above, and that the fusing station will not only hold cut products but also residual materials and slag, etc. In addition to this, when using an automatic NC fusing machine, it may take time to program the fusing data, resulting in long setup times and reduced machine availability. There is a risk of Particularly in the case of high-variety, low-volume production or single-item production, the number of programs increases, so programming takes time, which can further reduce the machine's operating rate, making NC automatic fusing machines and copying fusing machines expensive. Considering that, it is not profitable,
There is a risk that the original purpose of introducing these automatic fusing machines will be lost.

This idea was made in view of the above circumstances, and the purpose is to provide an automatic fusing machine that can improve the operating rate. Two fusing stations are arranged at approximately the same height, and a gate-shaped support is provided that moves reciprocally across these fusing stations, and a fusing torch and a drilling drill head are attached to the portal-shaped support in the direction of movement. It is attached so that it can reciprocate in a direction orthogonal to the cylinder, and is equipped with an external storage medium that stores fusing data, and a removable control device controls the portal support, the drilling drill head, and the fusing torch to obtain predetermined data. The present invention is configured to suitably cut the material on each of the cutting stations along the cutting line.

Next, the operation of the automatic fusing machine configured as described above will be explained.

First, the creation of the fusing data will be explained. The fusing data is for controlling the movement and stopping of the portal support 8 and the moving table 14, as well as the operations of the drilling drill head 18, the fusing torch 19, etc. It is preferable to use a programming device with a tube display (CRT programming device). By using such a programming device, you can program the fusing data interactively while looking at the display, and you can also check its reliability, so you can easily and quickly program the fusing data without any special knowledge. can be created. The fusing data created by the CRT programming device is stored in an external storage medium, for example, a magnetic bubble cassette 24, and then the magnetic bubble cassette 24 is transferred to the data reader 25 of the pendant operation panel 23 described above.
Set to . In this state, the pendant operation panel 23
When you press the start switch, magnetic bubble cassette 2
The fusing data stored in 4 is read and sent to the NC board 29 via the microcomputer 28.
and the programmable control panel 26, and as a result, the gate-shaped support 8, the movable table 14, etc. move to the first fusing station 1 where the material 3 is installed in advance, and start fusing. That is, first, the drill head 18 for drilling is positioned at the starting point of fusing, and a hole is drilled at the starting point of fusing. In addition, during drilling, the portal support 8
is clamped to the base 6, and the movable table 14 is clamped to the portal support 8. After drilling is completed, the fusing torch 19 is positioned at the edge of the hole, where low pressure gas is injected and combusted to preheat it, and high pressure gas is injected and combusted to start fusing. Thereafter, the portal support 8 and the moving table 14 are moved so that the fusing torch 19 is moved along the predetermined fusing line.
is moved based on the fusing data.

While the material 3 is being cut by fusing on the first fusing station 1 as described above, the other fusing station 2 is removing products obtained from the previous fusing operation and removing residual materials, slag, etc. At the same time as removing it, a new material 4 is installed, and in parallel, the fusing data for the next fusing is sent to the CRT.
Created by a programming device. As mentioned above, the programming can be done easily and quickly.

When the fusing at the first fusing station 1 is completed, the end buzzer sounds, and the operator attaches the magnetic bubble cassette 24 storing new fusing data to the data reader 25 of the pendant operation panel 23. fix. Next, after confirming the entire set state of the material 4, etc., press the start button, and the portal support 8 moves to the other fusing station 1 side, and the drilling drill head 18 and fusing torch 19 are activated based on the new fusing data.
The material 4 is fused and cut in the same manner as before.

While fusing is being performed at the other fusing station 2 in this way, the products and remaining materials on the first fusing station 1 that were obtained by fusing earlier are removed, and the slag is removed, etc. Organize and program new fusing data.

However, according to the above-mentioned automatic fusing machine, while cutting the material at one of the fusing stations, it is possible to organize the other fusing station, set the material, and create new fusing data. can.

It should be noted that the external storage medium in this invention is of course not limited to the magnetic bubble cassette shown in the above embodiment, and any storage medium that can be attached to and removed from the control device with a single touch may be used. .

As is clear from the above explanation, according to the automatic fusing machine of this invention, two fusing stations for setting the fusing material are installed at almost the same height, and the drilling drill head for drilling, the fusing torch, etc. are moved. In addition, since the fusing data for operation is stored in an external storage medium that can be attached to and removed from the control device, while fusing is being performed at one of the fusing stations, the other fusing station is being cut. It is possible to remove products and leftover materials, organize slag, and set new materials.Especially in the case of high-mix, low-volume production or one-piece production, new fusing data can be created during the drilling work. Therefore, according to the automatic fusing machine of this invention, it is possible to prepare for the next fusing operation while the previous fusing operation is being carried out, thereby shortening the downtime of the machine and increasing the operating rate. can be significantly improved compared to conventional methods.
