[Reference 1] Domestic Patent No. 10-0576058, April 26, 2006.

In general, the cooling fin is installed in an air conditioner and a radiator for cooling and heating to cool the heat generated from the device to enable the device to operate safely and smoothly.

The cooling fin has a shape in which the pleats are continuously formed in the upper and lower portions of the metal plate having a predetermined length, which continuously supplies a certain shape of the pleats to the upper and lower portions while supplying a material such as a round metal plate to maintain a constant tension. It is manufactured by going through a process of cutting to a certain length after molding.

The cooling fin manufacturing apparatus for manufacturing the cooling fins by such a process is disclosed in Document 1 above, and briefly describes the structure thereof as follows.

The cooling fin manufacturing apparatus has a supply part for supplying a material wound round, a tension holding part for maintaining a constant tension of the material supplied from the supply part, and a constant shape of the upper and lower parts of the material supplied with a constant tension from the tension holding part It consists of a molding part for continuously forming the wrinkles, a gap adjusting part for adjusting the wrinkles of the material formed by the molding part at regular intervals, and a cutting part for cutting the material whose wrinkles are adjusted at a constant interval by the gap adjusting part. It is.

Therefore, the material wound round through the supply part is supplied in a state of maintaining a constant tension by the tension retaining part, and then zigzag is continuously formed in the upper and lower parts in the molding part, and then the gap is properly adjusted through the gap adjusting part. After cutting to a certain length in the cut portion, a cooling fin of a predetermined length is formed in the upper and lower folds of a predetermined shape molded at regular intervals.

Here, the spacing adjusting part consists of a plurality of spacing adjusting rollers installed in multiple stages with a predetermined interval while forming two sets, and two spacing adjusting rollers forming a pair are rubbed with both sides of the material and between two spacing adjusting rollers of the other end. Using the difference in rotation speed, the gap between the upper and lower portions of the material is adjusted to the desired interval.

In addition, the two gap adjusting rollers are installed to be moved to the left and right in the opposite direction with respect to the center of the material by different moving blocks so that the distance between them is adjusted according to the width of the material.

 Therefore, when it is necessary to adjust the spacing of the two spacing rollers, use the operation handle installed in the moving block. Then, the moving block on one side moves in one direction along the lead screw, and the moving block on the other side moves in the other direction along the lead screw and the gap between the two gap adjusting rollers is adjusted.

However, as described above, the gap adjusting rollers of the gap adjusting part move the same distance in the left and right directions at the same time so that the gap is adjusted. In the case of deformation such as bending of the material to one side, there was a problem that can not be corrected. As a result, the defective products are mass-produced, resulting in a drop in manufacturing efficiency.

And if one of the gap adjusting rollers has more wear than the other gap adjusting rollers, even if only one of the gap adjusting rollers is replaced, the center of the rollers will not be centered. There was also a problem that needs to be replaced. This also results in costly maintenance.

The present invention has been invented to solve the above problems, to correct the deformation of the material such as bending in the longitudinal direction in the spacing adjuster to prevent the occurrence of defective products and increase the service life of the spacing adjusting roller to reduce the maintenance cost A supply unit for supplying a material wound roundly so as to be possible; A tension holding unit for maintaining a constant tension of the material supplied from the supply unit; A molding part which continuously forms wrinkles of a predetermined shape on the upper and lower portions of the material supplied at a constant tension from the tension holding part; The gap is controlled by a moving block in which two interval adjusting rollers, which are installed in multiple stages and are rotated integrally by a drive shaft with a drive motor, are screwed in different screw directions to the lead screw at regular intervals. A spacing adjusting unit which is installed so as to adjust wrinkles of the material formed by the forming unit at a predetermined interval; Cutting portion for cutting to a certain length of the material, the wrinkles are adjusted at regular intervals by the interval adjusting portion; In the configured cooling fin manufacturing apparatus, the drive shaft of the spacing adjusting unit is composed of a spline shaft so that the moving block can move freely in the left and right direction, the moving block of the spacing adjusting unit is screwed to each of the different lead screws It is an object to provide a cooling fin manufacturing apparatus.

The present invention has a structure in which the two spacing rollers as a pair are moved independently of each other to adjust the spacing between each other, so that the spacing between the two spacing rollers can be properly adjusted when deformation such as bending of the material in the longitudinal direction occurs. As it can be adjusted, it is very easy to correct the deformation of the material, which significantly lowers the incidence of defects.There is no need to replace both the gap adjusting rollers when the wear level of the two gap adjusting rollers is different. There is also a significant savings.

A spacing adjusting unit 4 installed to adjust the spacing between the two by 8b and adjusting the wrinkles R of the material M formed by the shaping unit 3 at a predetermined interval; A cutting section 5 for cutting the material whose wrinkles R are adjusted at regular intervals by the interval adjusting section 4 to a predetermined length; In the configured cooling fin manufacturing apparatus, the drive shaft of the gap adjusting portion 4 is composed of a spline shaft (9) the drive shaft so that the movable blocks (8a) (8b) can move freely in the left and right direction, the gap adjusting portion (4) The moving blocks 8a and 8b are characterized in that they are screwed to different lead screws 10a and 10b, respectively.

Horizontal bevel gears 13a and 13b meshed with vertical bevel gears 12a and 12b provided on the roller shafts 11a and 11b of the spacing adjusting rollers 7a and 7b on both sides of the spline shaft 9. Is extrapolated, and a drive motor 6 is connected to one end of the spline shaft 9 via a coupling 14.

At one end of the lead screws 10a and 10b, operation handles 15a and 15b for adjusting the position of each of the gap adjusting rollers 7a and 7b are provided.

At the lower ends of the movable blocks 8a and 8b, sliding blocks 18a and 18b that slide freely along the guide rails 17 installed on the horizontal frame 16 to be slidable in the left and right directions are installed.

Upper and lower guide plates 19 and lower guide plates 20 are installed at upper and lower portions between the gap adjusting rollers 7a and 7b to prevent separation of the material M, and the upper guide plate 19 is opened and closed. It is comprised so that it may be interrupted by the valve 21.

In the figure, reference numeral 22 denotes a vertical frame 22 that supports the spline shaft 9 and the lead screws 10a and 10b.

Cooling fin manufacturing apparatus 100 of the present invention configured as described above is a device for manufacturing a cooling fin used in air conditioners and radiators for cooling and heating, as shown in FIG.

In particular, the cooling fin manufacturing apparatus 100 of the present invention after the continuous forming of the pleats (R) in the upper and lower portions of the material (M) in the molding section (3) interval adjusting unit for adjusting the interval of the pleats (R) Its major feature is its improved structure, which reduces the incidence of defects and reduces maintenance costs.

This is achieved by the structure in which the two space adjusting rollers 7a and 7b provided in multiple stages of the space adjusting unit 4 move independently of each other to adjust the space between each other.

That is, as shown in Figs. 2 to 4, the drive shaft to which the power of the drive motor 6 is transmitted is composed of a spline shaft 9 in which gears are formed in the longitudinal direction, and the two gap adjusting rollers 7a and 7b. The movable blocks 8a and 8b, respectively, are screwed to different lead screws 10a and 10b.

Therefore, when adjusting the distance between the two gap adjusting rollers 7a and 7b to fit the various widths of the material M, the lead screws 10a and 10b are rotated using the respective operation handles 15a and 15b. By rotating, the two gap adjusting rollers 7a and 7b can be moved independently to adjust the gap between them.

This is because as the movable blocks 8a and 8b with the space adjusting rollers 7a and 7b are screwed to the lead screws 10a and 10b, respectively, the lead screws are operated through the operation of the operation handles 15a and 15b. As the 10a and 10b are rotated, the movable blocks 8a and 8b are independently horizontally moved along the spline shaft 9 which becomes the drive shaft.

In this case, as the sliding blocks 18a and 18b are installed at the lower ends of the movable blocks 8a and 8b, the movable blocks 8a and 8b can be slid smoothly along the guide rails 17 installed on the horizontal frame 16. do.

Accordingly, the two gap adjusting rollers 7a and 7b move independently of each other so that the gaps are arbitrarily adjusted so that the material M entering the gap adjusting unit 4 in the state in which the wrinkles R are molded in the forming unit 3 is formed. It can be located at different distances from the center of the.

As a result, the two gap adjusting rollers are integrally moved by the same distance from the center of the material M, and the gaps are adjusted. It is also possible to completely solve the conventional problem that has been shortened.

That is, since the positions of the two gap adjusting rollers 7a and 7b installed in multiple stages can be freely moved as shown in FIG. 5, the deformation of the raw material M is immediately corrected. Even if the wear level of the two gap adjusting rollers 7a and 7b is different, the gap between the two gap adjusting rollers 7a and 7b is adjusted without replacing all of them, or only the gap adjusting rollers 7a and 7b with heavy wear are replaced. Just do it.
