Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described below. The embodiments are provided to explain the present invention to a person having ordinary skill in the art to which the present invention belongs. Accordingly, the shape of each element shown in the drawings may be exaggerated to emphasize a clearer description.

Generally, the manufacturing process of the booth bar can be divided into a melting process, a heating process, an extrusion process, a surface treatment process, a drawing process, a calibration process, and a cutting process. The dissolving process is a process for making a cylindrical shaped billet by dissolving the raw material and is formed into a cylindrical shape so as to be easily extruded by a cylinder and a piston in an extrusion process to be described later.

In the heating process, the billet is heated to a temperature of 800 to 900 ° C. to facilitate the firing, thereby facilitating extrusion in a subsequent extrusion process. The heated billet is extruded by the cylinder and piston of the extruder in the extrusion process and has the shape of a plate-shaped bus bar. The booth bar extruded in plate form moves to the surface treatment process.

The surface treatment process is a process of washing the surface of the bus bar extruded in a plate shape. In order to remove the oxide film formed on the surface in the heating process and the extrusion process, the bus bar is immersed in dilute sulfuric acid and then cleaned with a mop.

After the surface treatment process, the busbar is passed through the drawing die of the drawing process, rounding the four corners, and the busbar is completed. The booth bar is calibrated by the calibrator of the calibration process for bending and camber deformation, cut to the desired length by the cutter in the cutting process, and then shipped.

However, in the above process, each of the individual processes proceeds, and there is a disadvantage that the worker directly moves the booth bar to which the individual process has been completed to the next process.

FIG. 1 is a flowchart schematically showing a booth bar manufacturing process according to an embodiment of the present invention. Unlike the booth bar manufacturing process described above, a booth bar is manufactured using the slab of the same material, and each process is connected to each other to manufacture the booth bar through the slab introduction. The slab is manufactured through a slitting process to a plurality of booths, and the rounding process for four edges and edges is completed through the rounding process of the busbar. Thereafter, the busbar is calibrated through the calibration process to twist and bend deformation, and is cut to the desired length through the cutting process. Hereinafter, the apparatus used in each step will be described in detail.

The upper conveying rollers 17a are spaced apart from each other on the upper rotary shaft 18a and the upper blade 16a is disposed on the upper rotary shaft 18a and disposed between the upper conveying rollers 17a. The upper blade 16a is in the shape of a disk, and the upper blade 16a has a larger diameter than the upper feed roller 17a. The upper blade 16a has a "V" shaped cutting edge formed on the edge. The upper blade 16a rotates together with the upper rotating shaft 18a and the upper surface of the slab 1 is processed through the cutting blade of the upper blade 16a during rotation to form a cut portion (or a notch) (N) (Fig. 4).

By the above-described method, the slits 1 are formed on the upper and lower surfaces of the slab 1, respectively, and burrs are not formed on the cut surfaces when the slab 1 is subsequently cut.

Since the upper blade 16a and the lower blade 16b may be damaged by the collision when forming the cut portion N, the cut portion should not have a depth more than half the thickness of the slab 1, And the lower blade 16b should be disposed with a certain distance therebetween. Then, the slab 1 is moved toward the main slitting unit 5 through the conveying rollers 17. Then,

Likewise, the lower rolling axis 24 is installed at the lower part of the bus bar 1a, and the lower rolling roll 25 is installed at the lower rolling axis 22. Although two upper rolls 23 and a lower rolling roll 25 are described in this embodiment, the upper rolling roll 23 and the lower rolling roll 25 may be three or more. Therefore, a rounding process for a plurality of bus bars 1a is possible, and a continuous rounding process is possible through the continuously rotating upper rolling roll 23 and the lower rolling roll 25.

The upper rolling shaft 22 and the lower rolling shaft 25 are connected to a separate driving motor (not shown) and rotated by a driving motor, 22 and the lower rolling axis 24, respectively.

The first and second processing rolls 32 and 34 are connected to a separate driving motor (not shown) and can be rotated by the driving motor. Although two sets of the first and second processing rolls 32 and 34 are described in this embodiment, the number of the first and second processing rolls 32 and 34 may be three or more. Accordingly, a rounding process can be performed with respect to the edges of the plurality of bus bars 1a, and a continuous rounding process is possible through the first and second processing rolls 32 and 34 which are continuously rotated.

The bus bar 1a is disposed between the first and second processing rolls 32 and 34 and can be advanced by the rotation of the first and second processing rolls 32 and 34.
