Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shaped steel processing machine capable of performing cutting, drilling, and groove processing on steel frame building members such as H-shaped steel and columns.

[0002]

2. Description of the Related Art Generally, steel frame building members are roughly classified into H-shaped steel, columns and plates. Among the steel frame building members, particularly for H-shaped steel, a hole punching machine, a cutting machine, and a groove machine are used to separately perform drilling, cutting, and groove machining. Furthermore, welding is performed by a welding machine as needed.

[0003]

By the way, in the case where the H-shaped steel is machined as described above, when the punching machine, the cutting machine and the beveling machine are lined up and arranged in series, at least one person is provided for each machine. Workers are required. Further, when considering the processing tact, the space is required at least for the length of the H-shaped steel to be processed on the carry-in and carry-out side of the punching machine, and the same can be said for the cutting machine and the groove machine.
Therefore, there is a problem that a large number of operators and spaces are required to process the H-section steel. Further, since the drilling machine performs various drilling operations, it is necessary to replace the drill and deburring work. Furthermore, the setup work was required between the machines.

The object of the present invention is to save labor and space and to change tools in order to solve the above problems.
It is an object of the present invention to provide a die-steel processing machine that reduces setup work and is capable of performing drilling, cutting, and beveling with a single machine.

[0005]

In order to achieve the above object, the present invention is directed to a work table on which a section steel is placed, a gate frame provided over the work table, and the gate frame. And a support frame having a heat cutting processing head provided in the heat cutting processing head, wherein the heat cutting processing head is movable in the X, Y, and Z-axis directions, and the tip of the heat cutting processing head is the longitudinal direction of the shaped steel material. It is characterized in that it is provided so as to be swingable so as to be oriented in the direction, the width direction and the height direction.

In the die steel processing machine, it is desirable that the die steel on the work table and the gate frame be relatively provided in the longitudinal direction of the die steel. Further, the support frame is movably provided on the left and right portions and the upper portion of the gate type frame, or is fixedly provided on each of them.

[0007]

[Operation] By adopting the die steel machine of the present invention,
The shape steel to be processed is placed on the work table. The thermal cutting head provided on the support frame provided on the gate frame is moved in the X-, Y-, and Z-axis directions on the model steel placed on the work table, and the tip of the thermal cutting head is moved. The shaped steel is swung so as to be oriented in the longitudinal direction, the width direction and the height direction, and drilling, cutting and groove processing are performed. Moreover, the supporting frame provided with the thermal cutting head is moved to the left and right parts and the upper part of the portal frame, and the mold steel on the work table and the portal frame are relatively moved in the longitudinal direction of the mold steel. , On the required length of the mold steel in the longitudinal direction, and on the left and right of the mold steel,
Drilling from the top, cutting, and groove processing are performed efficiently.

Further, if the supporting frames provided with the heat cutting heads are respectively provided on the left and right portions and the upper portion of the gate-shaped frame, three heat cutting heads are provided on the left and right sides of the die steel.
Since drilling, cutting, and groove processing are performed simultaneously from above, processing is performed more efficiently than moving by moving one thermal cutting processing head left and right and upward.

Will be moved by itself while being guided by the guide rail 45. As a result, the support frame 49 is moved and positioned to the A position on the upper frame 9U of the gate type frame 9 and the B and C positions on the side frames 9R and 9L.

On the support frame 49, for example, a laser processing head body 77 as a thermal cutting processing head body is X,
It is provided so as to be movable in the Y and Z axis directions. More specifically, when the support frame 7 is in the A position,
As shown in FIG. 1, the support frame 7 is provided with a Y-axis moving body 79 that is movable in the Y-axis direction by, for example, a drive system of a drive motor, a ball screw, and a nut member. The Y-axis moving body 79 is also provided with an X-axis moving body 81 which is movable in the X-axis direction by, for example, a drive system of a drive motor, a ball screw and a nut member.

7 is moved in the X-, Y-, and Z-axis directions, and the tip of the laser processing head 87 is further swung in the longitudinal direction, the width direction, and the height direction of the H-shaped steel W, so that the H-shaped steel W is punched and cut. Alternatively, groove processing can be easily performed. Further, by sending the H-shaped steel W to the gate-shaped frame 9, the H-shaped steel W can be continuously punched, cut and grooved. In the present embodiment, the example in which the H-shaped steel W is moved forward with respect to the gate-shaped frame 9 has been described, but the gate-shaped frame 9 is moved with respect to the H-shaped steel W by a drive system such as a ball screw and a nut member. Alternatively, both may be moved relative to each other.

Since the laser processing head 87 can be used for punching, cutting and groove processing, it is possible to save manpower and space, and it is possible to reduce the setup work as compared with the conventional case. ..

FIG. 6 shows another embodiment as an alternative to FIG. 6 is different from FIG. 1 in that the inside of the gate-shaped frame 9 has a normal shape, and the upper frame 9U, the side frames 9R and 9L of the gate-shaped frame 9 are
The support frame 49 is fixed to the positions B and C, and the Y-axis, X-axis and Z-axis moving bodies 79,
81 and 83 are moved in the X, Y and Z axis directions,
The laser processing head 87 is swingably provided so as to direct the laser processing head 87 in the longitudinal direction, the width direction, and the height direction of the H-shaped steel W.
Since other configurations are almost the same, detailed description will be omitted.

Therefore, although the same operation and effect as those shown in FIG. 1 are obtained, compared with FIG. 1, since three laser processing heads 87 are fixedly provided in three directions, holes are formed, Since cutting and groove processing can be performed at the same time, they can be performed more efficiently.

It should be noted that. The present invention is not limited to the embodiments described above, but can be implemented in other modes by making appropriate changes. In this embodiment, the laser cutting head has been described as an example of the thermal cutting processing head, but a plasma processing head using a plasma or gas beam or a gas processing head is also applicable.
