Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Field of Use" The present invention is utilized when, for example, a long object such as a skin plate, which is a member of a box column, is beveled along its longitudinal direction.

"Prior Art" Conventionally, when manufacturing a box column used as a column for architecture, it is generally constructed by combining four elongated plate-like members called skin plates. At this time, in order to weld the abutment surfaces of the longitudinal edges of the skin plates to be joined together, and also to weld multiple reinforcing plates called diaphragms or rib plates to the skin plates that partition the column space. First, prepare a predetermined bevel on the skin plate to be joined.

Specifically, it is as shown in FIGS. 6 and 7. These figures show the state in which the edges of the grooved skin plates are assembled so as to vertically abut and before welding.

FIG. 6 shows a groove shape generally called a dosing groove. Reference numerals 1 and 2 are skin plates; skin plate 1 is not beveled, and only skin plate 2 is beveled. These skin plates 1
．． 2 are arranged so that they abut each other vertically at their ends. In the case of this wedge-shaped groove, one skin plate, l, is not beveled;
The edge of the other skin plate 2 is beveled to form beveling surfaces 2a and 2b. These grooved surfaces 2a and 2b are mutually continuous surfaces, and the surface 2b
is formed into a deeper cut than the surface 2a. In addition, a rectangular cut 2 formed in the skin plate 2
c is formed so as to be located a little further away than the end of the groove surface 2b. These grooved surfaces are 2m long.
.

The skin plates 1.2 are joined by injecting solvent into 2b, 2c.

Here, the reason why the groove shape is varied is, for example, in order to reinforce the parts that particularly require joint strength when a beam or the like is further provided on the skin plates 1 and 2.

FIG. 7 is a diagram showing a groove shape generally called a V-shaped groove. In the figure, reference numeral 3.4 indicates a beveled skin plate e, and similar to that shown in FIG. 1, these skin plates 1 and 3.4 are abutted vertically at their ends It is arranged. skin plate 3
．． The mutually abutted edges of 4 are beveled to form a beveled surface 3a.

3b, 3c% 4a, 4b, 4c, 4d are formed.

In this case as well, skin plate 3.4 is
join.

When groove-processing the longitudinal edge of a skin plate in this way, the operator writes the groove shape and its range on the workpiece in advance, sets the port of the portable gas cutting machine to the groove conditions, The groove was machined, and areas where the groove shape changed were finished later.

``Problem to be Solved by the Invention J'' However, in this type of groove processing, continuous processing is not possible because the groove shape differs depending on the location.

Also, when creating a beveling on a workpiece, the operator writes down the bevel shape and its range, uses the port of the portable gas cutting machine to process the beveling, and then finishes the areas with different bevel shapes later. Because of this process, work efficiency was poor, and at the same time,
There were drawbacks such as differences in the groove shape depending on the level of skill of the operator. Furthermore, since it is difficult to process two sides at the same time, there is a drawback that the workpiece is bent.

Therefore, an object of the present invention is to simultaneously and continuously form a bevel on both sides of a workpiece.

The operation of the control device will be explained with reference to FIG.

5TEP l receives processing information created in advance by the computer 40 shown in FIG. At this time, data is received via a communication circuit.

In 5TEP 2, machining is started in response to a machining start signal from the operation panel 50 shown in FIG. When machining is started, commands are given to each of the traveling vehicle 6, lateral movement table 8.9.1O111, vertical movement shaft 16, and rotation movement table 19 so that the tip of the torch is positioned at the position specified by the processing information. give. Target position of the tip of the cutting torch 21 (cutting position)
When reaching , a 5TEP3 cut is made. When making a cut, a command is given to the gas output control circuit 46 by the judgment circuit 41, and the workpiece 30, 31 is beveled while controlling the output of the cutting torch 21.

Next, bevel processing is started at 5TEP4.
The fixed beveling process continues until 5TEP5 when the bevel changes. At this time, the traveling vehicle 6 is the only moving means that operates.

Next, when the present device reaches a change point of the groove shape in 5TEP5, the groove shape is changed within the change section specified by the processing information.

At this time, in order to obtain a smooth groove surface in the section where the groove shape changes, the judgment circuit 41 determines whether each moving means (vehicle 6,
Lateral moving table 8.9.10.11. The respective moving means are controlled so that the vertical movement shaft 16 and the rotary movement table 19) simultaneously end their operations at the end point of the groove change section.

When the change in the groove shape is completed, only the traveling vehicle 6 continues to run while maintaining the current groove shape until the next change point or the end point of the groove machining, as shown in 5TEP6.

Next, at 5TEP7, if the groove shape is to be further changed depending on the contents of the machining information, the machining is temporarily interrupted at 5TEP5, and if the machining is to be resumed from a newly specified point, the operation returns to 5TEP3 and continues.

According to the above-described beveling method and processing apparatus, beveling can be performed continuously even when the groove shapes are different.
