Description

[0001] The present invention relates to a busbar manufacturing apparatus using a sequential round-forming apparatus,

The present invention relates to a booth bar manufacturing apparatus using a sequential round forming apparatus, and more particularly, to a booth bar manufacturing apparatus using a sequential round forming apparatus, To " a bus bar manufacturing apparatus using a sequential round molding apparatus "

Generally, a bus bar (BB) is also referred to as a copper band. The bus bar is mainly installed in a cubicle inside a transformer room, and may be installed in many places. In addition, as shown in FIG. 1, bus ducts are installed in a large number of rows to transfer a large amount of current.

That is, the bus bar BB is a connecting piece used for an electric distribution board, a distribution board, a control board, etc., and connects the terminals to the terminals, and is made of a thick plate such as a copper plate or aluminum. Busbar (BB) has the advantage of delivering more electricity from the same volume of conductors, and is now widely used as a replacement for cables in large capacity distribution systems.

2, the manufacturing process of the booth bar BB includes a melting process YH, a heating process HT, an extrusion process PC, a surface treatment ST, a drawing process SS, A calibration process (RP), and a cutting process (CT).

The dissolution process YH is a process for making a cylindrical bullet BL by dissolving the raw material and is a process for producing a bullet BL in a cylindrical form so as to facilitate extrusion by a cylinder CY and a piston PT in an extrusion process .

In the heating process (HT), the billet (BL) is heated to a temperature of 800 to 900 ° C. to facilitate firing, thereby facilitating extrusion in a subsequent process, ie, an extrusion process (PC). The heated billet BL is extruded by the cylinder CY and the piston PT of the extruder PM in the extrusion process PC and has the shape of a plate-shaped bus bar. The booth bar extruded in plate form moves to the surface treatment process (ST).

The surface treatment process (ST) is a process of washing the surface of the bus bar extruded in a plate shape. To remove the oxide film formed on the surface in the heating process (HT) and the extrusion process (PC), the bus bar is immersed in diluted sulfuric acid Wash with a mop.

After the surface treatment process (ST), the bus bar is passed through the drawing die (DS) of the drawing process (SS) to round the four corners, and the bus bar (BB) is completed. The bus bar BB is calibrated by the calibrator RM of the calibration process RP to correct twist and bending deformation and is cut to a predetermined length by the cutter CM in the cutting process CT and then shipped.

However, each of the above-described processes has a disadvantage in that the individual process is carried out and the worker moves directly to the next process of the individual process-completed bus bar.

Therefore, in order to solve the above-mentioned problem, Korean Patent Registration No. 10-1500618, which is a continuous booth bar manufacturing apparatus using a slab, has been proposed.

3 and 4, the booth bar manufacturing apparatus includes an upper rolling shaft 21a and a lower rolling shaft 21b respectively installed on upper and lower portions of a plurality of booth bars, The upper and lower rolling shafts 21a and 21b are rotatable together with the upper and lower rolling shafts 21a and 21b respectively. One or more upper rolling rolls 23a formed so as to correspond to the machining grooves 25b and rounded in a state that each of the bus bars is accommodated in the upper machining groove 25a and the lower machining groove 25b, Rolling roll 23b. "

As described above, the above-mentioned prior art processes the angled portions and the like of the corners of the bus bar by using the upper and lower rolling rolls 20 having the upper rolling roll 23a and the lower rolling roll 23b .

However, the conventional art has the following problems as shown in FIG.

First, there is a problem that the shape of the bus bar protrudes to the left and right depending on the degree of pressing of the upper and lower rolling rolls, or the round of the bus bar is incompletely formed.

Second, there is a problem in that it is not possible to adjust the degree of pressurization according to the width of the slitted bus bar.

Third, since there is a pressing deviation according to the right and left positions on the upper and lower rolling rolls, there is a problem that the cross section of the bus bar is bent downward.

Korean Patent Laid-Open Publication No. 10-2011-0122324, entitled " Manufacturing Method of Busbar, " Korean Patent Registration No. 10-1500618 entitled "Device for Continuous Production of Busbars Using Slabs" (Registered on Mar.

Further, the rounding roll presses the side of the booth bar to round-shape the corner of the booth bar.

In addition, the first to n-th rounding rolls (n is a natural number of 2 or more) are formed in correspondence with the first to n-th rounding grooves, one by one in a bilaterally symmetrical manner along the traveling direction of the bus bar.

Also, the first to nth rounding grooves gradually increase in radius of the forming curvature to be rounded corresponding to the corners of the bus bar in accordance with the traveling direction of the bus bar.

According to the embodiment of the present invention, since the bus bar is sequentially rounded, there is an advantage that the occurrence of bending is remarkably reduced.

Further, even if the width of the slitted busbars is not constant, it is possible to solve the problem by side pressure, which is advantageous in that the quality of the busbars can be kept constant.

In addition, there is an advantage that a side edge or a round-ungenerable portion that can be generated in the related art can be solved.

With reference to the conveying direction of the slab S, (120) is located next to the preliminary slitting unit (110). The slab S passes through the preliminary slitting unit 110 and the main slitting unit 120 in order to cut (or slit) into a plurality of bus bars s1.

On the other hand, the slab S can be fed in one direction while being unwound from the uncoiler through a feeding device (not shown) while being wound around an uncoiler (not shown), and the preliminary slitting unit 110 and the main slitting Unit 120. < / RTI >

The slitting device 100 can cut and adjust the width (width) of the bus bar s1 according to the purpose.

8, the preliminary slitting unit 110 is provided with a cutting rotary shaft (not shown), a cutting conveying roller 111, and a cutting blade 113. The incision rotary shaft is connected to the incision frame 115 installed on both sides of the slab S, and the incision frame 115 supports both sides of the incision rotary shaft. The incision rotary shaft is connected to a separate drive motor (not shown) and rotated by the drive motor. The incision transfer roller 111 and the incision blade 113 are installed on the incision rotation axis and rotate together with the incision rotation axis.

The cutting blade 113 is a circumferential blade that cuts the slab S and is located at the top or bottom of the slab S. [ The incision transfer rollers 111 are spaced apart from each other and are provided on the incision rotation axis, and the incision blade 113 is disposed on the incision rotation axis and disposed between the incision transfer rollers 111. The cutting blade 113 is in the shape of a disk, and the cutting blade 113 has a larger diameter than the cutting feed roller 111. The cutting blade 113 has a circular cutting edge. The incision blade 113 rotates together with the incision rotary shaft and inclines the surface of the slab S along the moving direction through the cutting edge of the incision blade 113 at the time of rotation to form the incision.

On the other hand, at the time of forming the cut portion, the cut portion may have a depth of half or more of the thickness of the slab S. Thereafter, the slab S is moved toward the main slitting unit 120 through the incision conveying roller 111.

8, the main slitting unit 120 includes a cutting rotary shaft (not shown) and a cutting conveying roller 121, and a cutting disk 123. The cutting rotary shaft (not shown) is connected to a cutting frame 125 provided on both sides of the slab S, and the cutting frame 125 supports both sides of the cutting rotary shaft. The cutting rotary shaft is connected to a separate drive motor (not shown) and rotated by the drive motor. The cutting feed roller 121 and the cutting disc 123 are provided on the cutting rotation axis and rotate together with the cutting rotation axis.

The cutting disc 123 is in the shape of a disc and is provided on the cutting rotary shaft as shown in FIG. 9, and constitutes a plurality of cutting discs 123.

Similarly, the cut feed roller 121 is located at the upper and lower portions of the slab S, respectively. The cut conveying roller 121 contacts the surface of the slab S and rotates together with a cutting rotary shaft (not shown) to convey the slab S. The cut feed roller 121 is provided on the cutting rotary shaft, and the cut feed roller 121 is disposed between the cut disks 123.

8, the slab S having passed through the preliminary slitting unit 110 moves to the main slitting unit 120, and the cutting disc 123 is disposed on one side of the cut-out portion. As described above, the cutting disk 123 presses one side of the incision portion of the slab S, which is drawn in during the rotation, downward. Accordingly, the slab S is pressed on one side of the incision portion, and the slab S is cut along the incision portion to form a plurality of the bus bars s1.

In other words, the cutting disc 123 separates the slab S by a rotating plate when passing through the slab S, and the separated plurality of the bus bars s1 are separated by the cut feed roller 121 Conveyed and discharged. Through such a method, the slab S can be continuously separated (or slit), and a plurality of the bus bars s1 can be continuously formed.

The cut surface of the bus bar s1 is formed in the process of forming the cut through the cutter blade 113. The edge of the cutout minimizes burrs when the slab S is separated , But prevents deformation of the bus bar (s1). Thereafter, the cutting disk 123 can separate the slab S along the incision with the bus bar s1. That is, by minimizing the portion processed through the cutting disk 123, deformation of the bus bar s1 can be prevented, and occurrence of burrs can be minimized. Therefore, the additional operation of removing the burr of the bus bar s1 can be omitted or minimized.

2. ROUNDING Process (S200)

Fig. 11 is a schematic perspective view showing a round molding apparatus 200 according to an embodiment of the present invention, and Fig. 12 is a diagram showing a schematic cross-sectional view of Fig.

FIG. 13 is a cross-sectional view taken along the line A-A 'in FIG. 11, FIG. 14 is a cross-sectional view taken along the line B-B' in FIG. 11, and FIG. 15 is a cross-sectional view taken along the line C-C 'in FIG.

As shown in FIG. 11, the bus bar s1 manufactured through the slitting apparatus 100 passes through the round molding apparatus 200 and is processed into a streamlined round at angled portions with respect to the corners.

As described above, in the prior art, the corners of the booth bar s1 are rounded by pressing the upper and lower portions by the upper and lower rolling apparatuses. However, as shown in Figs. 5A, 5B and 5C, There have been problems such as burrs occurring along the middle point of the bar, less rounding of the corners, or left and right twist.

More specifically, when the bus bar can not be slit in a certain width in the slitting process, since the width of the round groove is fixed in the conventional vertical rolling apparatus of the rounding process, if the width of the slitted bus bar is large, 5 (a), if the width of the slit busbars is small, the round is incompletely formed as shown in FIG. 5 (b) due to the upward and downward pressures, and the left and right sides Twisted phenomenon occurred.

That is, it is difficult for the booth bar produced in the slitting process to maintain a constant width due to the blade of the slitter, the tolerance between the blade and the blade, cutting by pressing, and the like. The above-mentioned problems with respect to the round molding occur.

Accordingly, these problems are solved through the round molding apparatus 200 of the present invention.

Further, when rounding the corners of the bus bar, the round molding apparatus 200 of the present invention presses the round molding sequentially several times, so that the quality can be improved as compared with the conventional one.

As shown in Figs. 11 and 12, the round molding apparatus 200 includes a rounding shaft 201, a rounding roll 203, and a support frame 207.

The rounding axis 201 may be divided into a left rounding axis 201a and a right rounding axis 201b on both sides of the bus bar s1.

The rounding roll 203 may be divided into a left rounding roll 203a provided on the left rounding shaft 201a and a right rounding roll 203b provided on the right rounding shaft 201b.

That is, the left rounding shaft 201a is installed on the left side of the bus bar s1, and the left rounding roll 203a is installed on the left rounding shaft 201a. Likewise, the right rounding shaft 201b is provided on the right side of the bus bar s1, and the right rounding roll 203b is provided on the right rounding shaft 201b.

In the present embodiment, the round molding apparatus 200 includes a pair of left and right rounding rolls 203a and 203b, and is provided with a pair of left and right symmetrically symmetrical They are arranged in three rows.

The left rounding shaft 201a and the right rounding shaft 201b are connected to a separate driving motor (not shown) and rotated by a driving motor. The left rounding roll 203a and the right rounding roll 203b are connected to a left rounding shaft 201a and the right rounding axis 201b.

11 and 12, the bus bar s1 is disposed between the left rounding roll 203a and the right rounding roll 203b to rotate the left rounding roll 203a and the right rounding roll 203b Lt; / RTI >

As shown in Fig. 12, the left rounding roll 203a has a left rounding groove 205a recessed from the outer circumferential surface, and likewise, the right rounding roll 203b has a right rounding groove 205b recessed from the outer circumferential surface. At this time, the left rounding groove 205a and the right rounding groove 205b are arranged to correspond to each other.

Each of the left rounding groove 205a and the right rounding groove 205b has a rounded cross section formed on a side parallel to the rounding shaft 201. [

The bus bar s1 is accommodated in the left rounding groove 205a and the right rounding groove 205b so that the left side face of the bus bar s1 contacts the inner face of the left rounding groove 205a, And the right side surface contacts the inner surface of the right rounding groove 205b. The left corner of the bus bar s1 is in contact with the rounded top surface in the left rounding groove 205a and the right corner of the bus bar s1 is in contact with the rounded top surface in the right rounding groove 205b. The left rounding roll 203a and the right rounding roll 203b rotate while pressing the bus bar s1 in a substantially horizontal direction so that the four corners and edges of the bus bar s1 are aligned with the left rounding groove Can be round-processed by the right rounding groove 205a and the right rounding groove 205b.

11, in the round molding apparatus 200, the rounding rolls 203 sequentially move the first, second, and third rounding rolls 210, 220, and 220 along the traveling direction of the bus bar s1, 230).

Each of the first, second, and third rounding rolls 210, 220, and 230 has a left rounding groove 205a and a right rounding groove 205b that can round corners of the bus bar s1 A rounding groove 205 is formed.

The forming radius of curvature R of the first rounding roll 210 positioned near the entrance according to the traveling direction of the bus bar s1 is greater than the forming radius of curvature R of the second rounding roll 220, And the forming radius of curvature R of the second rounding roll 220 is formed to be smaller than the forming radius of curvature R of the third rounding roll 230 located next.

That is, the rounding grooves 205 are sequentially formed deeply along the traveling direction of the bus bar s1 so that a final streamlined round is formed.

This is because it is not possible to round the four corners of the bus bar s1 to a desired shape when rounding once by the vertical rolling as in the prior art and it is not smooth to form rounded corners due to the limitation of the actual bus bar width .

Therefore, by sequentially rounding the bus bar s1 through the first to third rounding rolls 210, 220, 230 according to the embodiment of the present invention, the conventional incomplete round shape or the remaining burrs or burrs It is possible to round off the booth bar s1 in a desired shape while removing an edge.

Meanwhile, in the present invention, the first to third rounding rolls 210, 220 and 230 are exemplary quantities, and the number of the rounding rolls 203 can be added according to the degree of pressing, It is obvious that more precise round molding is possible.

12, the rounding apparatus 200 can be finely adjusted up and down on the rounding shaft 201 so that the minute turning of the bus bar s1 and the fine turning of the bus bar s1 ), The rounding of the bus bar s1, and the like.

On the other hand, as shown in FIG. 16, round processing results can be understood through the schematic cross-section of the bus bar s1 after the slitting (a) or the rounding (b).

The apparatus is provided on the support frame 207 and the support frame 207, A rounding shaft 201 having a vertical axis formed on both sides of the bar s1, a vertical columnar body 201 formed on the rounding shaft 201 and formed with a rounding groove 205 which is rotated together with the rounding shaft 201, A rounding roll 203 is provided.

Further, the rounding roll 203 presses the side surface of the bus bar s1 to round-shape the corner of the bus bar s1.

In addition, the rounding rolls 203 may include a first rounding roll 210 having a first rounding groove sequentially in pairs horizontally symmetrically along the traveling direction of the bus bar s1, a second rounding roll 210 having a second rounding groove 220, and a third rounding roll 230 having a third rounding groove are formed.

In addition, the first, second, and third rounding grooves gradually increase in the radius of curvature R of the shape to be rounded corresponding to the corners of the bus bar s1 in accordance with the traveling direction of the bus bar s1. (The forming depth for the corners of the bus bar gradually increases.)

That is, the first to nth rounding rolls (n is a natural number of 2 or more) are formed in the rounding rolls 203 corresponding to the first to nth rounding grooves, and the first to nth rounding grooves are formed in the bus bars s1, the radius of curvature R of the molding to be rounded is gradually increased in accordance with the advancing direction of the bus bar s1.

The left and right calibration rolls 313a and 313b are arranged alternately on the right and left sides along the conveying direction of the bus bar s1 and the calibration vertical axis 311 moves left or right by the rotation of the calibration screw 315, The right or left movement of the left and right calibration rolls 313a and 313b can press the left or right side of the booth bar and the interval between the left calibration roll 313a and the right calibration roll 313b can be adjusted may be smaller than the width (W) of the slit (s1).

Therefore, the bus bar s1 is pressed to the left and right sides by the left and right movement of the left and right calibration rolls 313a and 313b in accordance with the rotation of the calibration screw 315, whereby the bus bar s1 is corrected .

The left and right calibration rolls 313a and 313b are installed around the left and right calibration vertical axes 311a and 311b and the calibration screw 315 is connected to the left and right calibration vertical axes 311a and 311b, (Not shown) and can be rotated by a driving motor. The bus bar s1 can be rotated by the left and right movement of the associated left and right calibration rolls 313a and 313b in accordance with the rotation of the calibration screw 315, It can be pressed to the right side.

In the embodiment of the present invention, five left calibrating rolls 313a and five right calibrating rolls 313b are illustratively constructed. In another embodiment of the present invention, 16 left and right calibration rolls 313a and 313b were tested and obtained satisfactory results.

That is, although the quantity of the calibrating rolls 313 may be variable depending on the installation space, it is possible to correct the lateral bending or bending because it increases the possible quantity.

In particular, in the past, vertical bending correction for the twist and bending deformation of the bus bar s1 was possible using a vertically correcting device, but there was no separate device for correcting the lateral bending, and it was difficult to bend the left and right.

10, the upper and lower thicknesses t of the bus bar s1 are relatively small as compared with the width W of the right and left sides, Even if the side was pressed, it was possible to correct the shape without deforming the shape.

However, when the bus bar s1 is pressed to both sides of the width W, the shape of the bus bar s1 is deformed and deformed rather than correcting the bending of the right and left sides of the bus bar s1. In order to solve the lateral bending of the bus bar s1, a plurality of pairs of horizontal rolls symmetrically arranged on the side of the bus bar s1 are pressed and pressed. However, the lateral bending can not be solved, Only the protruding problem occurred.

Therefore, in the related art, side correction to the booth bar s1 has been performed to the extent that it can not press the solenoid valve body s1 to the right and left sides so as to proceed to the next process.

That is, the side of the bus bar s1 was guided by a pair of horizontally symmetrical horizontal rolls, and the left and right guides were arranged to face each other in correspondence with each other to constitute a plurality of rows.

Therefore, as shown in Fig. 18, the side calibration leveler 310 is arranged so that the plurality of left calibration rolls 313a and the plurality of right calibration rolls 313b are staggered in a staggered manner without facing each other, It is more effective in correcting bending or warping.

Particularly, when the lateral correction leveler 310 is arranged to face each other like the left and right guide bars of the conventional bus bar s1 to correct lateral bending or bending, the same effect as the present invention can not be obtained.

It is determined that the right and left calibration rolls 313 which are arranged alternately with respect to the bus bar s1 are mutually leaned to induce the calibration according to the side pressure of the bus bar s1 to be performed more smoothly do.

20 is a view of a clearing device 320 according to an embodiment of the present invention.

The clearing device 320 may optionally be installed in front of the side calibration leveler 310.

The clearing device 320 located at the front end of the side calibration leveler 310 prevents the deterioration of the quality of the bus bar s1 due to foreign matter or other impurities adhering to the surface of the bus bar s1 during calibration of the bus bar s1 It is a device that is installed to do.

20, the clearing device 320 is an apparatus for removing various foreign substances, rolling oil, etc., which are adhered to or generated on the surface of the bus bar s1 while passing through the above-described devices, The surface of the bus bar s1 is cleaned by fixing a plurality of urethane elastic materials to the center 321 disposed above the surface 321 and fixing the surface 322 which can be wiped with a wipe or the like on the surface thereof.

The surface cleaning operation by the clearing device 320 may be performed by cleaning the surface of the metal material, that is, the surface of the booth bar s1 according to the present invention, by a physical treatment method or the like, Work can be done and it helps to produce a quality bus bar (s1).

As shown in FIGS. 21 and 22, a side calibration leveler 310 and a clearing device 320 according to an embodiment of the present invention can be identified illustratively.

23 is a view showing an up-down correcting apparatus 330 according to an embodiment of the present invention.

As shown in Fig. 23, the bus bar s1 passes through the side correction leveler 310 and then passes through the upper and lower straightening rollers 331 and 332 to correct the vertical deformation. The upper correcting roller 331 is installed on the upper part of the bus bar s1 and the lower correcting roller 332 is installed on the lower part of the bus bar s1. The upper and lower calibrating rollers 331 and 332 may be connected to a separate driving motor (not shown) and rotated by a driving motor, and the bus bar s1 may be rotated by the rotation of the upper and lower calibrating rollers 331 and 332 Lt; / RTI > The upper and lower calibrating rollers 331 and 332 are arranged alternately in accordance with the traveling direction of the bus bar s1 and the interval between the upper calibrating roller 331 and the lower calibrating roller 332 is different (T). Accordingly, the bus bar s1 is pressed upward and downward by the upper and lower straightening rollers 331 and 332, whereby the bus bar s1 can be vertically corrected.

In another embodiment of the present invention, the booth bar s1 passes through the vertical straightening device 330 and then passes through the secondary side correction leveler to correct the lateral bending deformation.

This allows the length of the production line to be allowed on the production floor to be limited or the side correction leveler 310 to be divided for easy equipment placement.

That is, the side correction leveler 310 can be divided into a first side correction leveler and a second correction leveler before and after the vertical correction device 330.
