Description

[0001] Embossed steel manufacturing apparatus using embossing cartridge and method [0002]

More particularly, the present invention relates to an apparatus and method for manufacturing an embossed steel sheet using an embossing cartridge, and more particularly, to a method and apparatus for manufacturing an embossed steel sheet using an embossing cartridge, To an apparatus and a method for manufacturing an embossed steel sheet using an embossing cartridge for forming a special curved line with an embossed or embossed shape and reducing a manufacturing process to reduce costs and productivity.

The embossing cartridge 100 is configured such that when the steel plate 170 is passed between the embossing work roll 110 and the elastic roll 140, the elastic roll 140 The embossed pattern is projected toward the elastic roll 140 on the steel plate 170 and the embossed pattern is impressed on the back surface of the steel plate 170. This is the most significant feature of the present invention.

That is, an apparatus and method for manufacturing an embossed steel sheet using an embossing cartridge according to a preferred embodiment of the present invention includes a temper rolling mill 200 and an embossing cartridge 100.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings for explaining an embossed steel sheet manufacturing apparatus and method using an embossing cartridge according to embodiments of the present invention.

FIG. 1 is a view showing the construction of an embossing cartridge of an embossing steel sheet manufacturing apparatus using an embossing cartridge according to a preferred embodiment of the present invention, and FIGS. 2 and 3 are cross-sectional views illustrating an embossing steel sheet manufacturing process using an embossing cartridge according to a preferred embodiment of the present invention. Fig.

1 to 3, an embossing steel plate manufacturing apparatus according to the present invention is manufactured by attaching an embossing cartridge 100, which is specially manufactured to a body of a skin pass mill (hereinafter referred to as SPM) 200, (Not shown).

Here, the temper rolling machine 200 is a device that adjusts the hardness of the steel plate 170 and smoothens the surface to withstand the machining.

The embossing cartridge 100 mounted on the roughing mill 200 includes an embossing work roll 110, a first support roll 120, a first support roll 130, an elastic roll 140, a second support roll 150, And a second support roll 160.

The embossing work roll 110 engraves the embossing pattern desired by the customer, and applies pressure to engage the embossed pattern on the steel plate 170.

The first support roll 120 is composed of a plurality of rolls and is positioned on the upper side of the embossing work roll 110 to prevent warping of the embossing work roll 110.

The first support rolls 130 are composed of a plurality of first support rolls 130 and are positioned in contact with the upper side of the first support rolls 120. At this time, the first support roll 130 is provided on the upper center portion of the first support roll 120. This is to prevent the first support roll 120 from being warped to prevent a fear of a slight crown phenomenon, thereby preventing a double bending phenomenon and preventing a bending phenomenon in which both sides of the roll are bent.

The elastic roll 140 is positioned below the embossing work roll 110 to be symmetrical with the embossing work roll 110 and contacts the underside of the embossing work roll 110 and is made of an elastic material such as rubber. At this time, since the elastic roll 140 has a great influence on the depth and contour of the pattern pattern imprinted on the embossing work roll, the elastic roll 140 is replaced with the corresponding elastic roll 140 according to the strength of the load of the embossing work roll 110, Pattern patterns can be implemented. That is, the embossing cartridge 100 can be freely replaced with the corresponding hardness elastic roll 140 according to the strength of the load and the embossing pattern pattern, so that various pattern patterns can be easily realized.

The second support rolls 150 are composed of a plurality of support rolls 150 and are positioned below the elastic rolls 140 to support the elastic rolls 140.

The second support rolls 160 are positioned on the lower side of the second support rolls 150, and a plurality of the second support rolls 160 are provided on the lower center. The second support roll 160 serves to prevent a bending phenomenon and a banding phenomenon of the second support roll 120.

First and second operation levers (not shown) are provided on the main body of the embossing cartridge 100 to precisely adjust the first support roll 130 and the second support roll 160, have. Thus, pattern patterns imprinted on the embossing work roll 110 can be variously embodied in the steel sheet 170. This creates the same effect as the Laser Cutter Presser method, which is expensive to manufacture.

That is, when the first operation lever is operated, the first support roll 130 can be pressed toward the embossing work roll 110. When the second operation lever is operated, the second support roll 160 is moved toward the elastic roll 140 side It is possible to pressurize. Accordingly, the pressure load applied to the elastic roll 140 of the embossing work roll 110 is adjusted so that the degree to which the embossed pattern protrudes toward the elastic roll can be adjusted on the steel strip.

In addition, the embossing cartridge 100 further includes an oil jetting section 180.

The oil injector 180 is installed on both sides of the embossing work roll 110 and the elastic roll 140 to spray the oil toward the steel plate 170 in a mist spraying manner. This is a structure that is absolutely necessary for the color and cold workability inherent in the steel plate 170 due to the importance of cooling and gloss of the heat generated during the rolling operation. The stabilized pattern is maintained by spraying the volatile special oil without mist, So that it is possible to manufacture a clean and beautiful embossed steel plate 170 by removing various dusts on the surface of the plate.

In addition, since the oil injecting unit 180 does not require a storage facility and a filter system, and a relatively small amount of mist is injected unlike the conventional apparatus, the mist injecting unit of 15 to 20 liters can be installed and used in small amounts.

Therefore, the embossing plate manufacturing apparatus using the embossing cartridge of the present invention can be manufactured by simply attaching the embossing cartridge 100, which is specially manufactured to the apparatus for rolling the steel sheet, The embossing cartridge 100 is provided with an embossing work roll 110 and an elastic roll 140 made of a rubber material so that the lower embossing work roll 110 can be lowered by the pressure load of the upper side embossing work roll 110. [ The elastic roll 140 is pressed, and the pattern is impressed on the steel plate 170 to the back surface, that is, the elastic roll 140 side.

In addition, when the steel sheet 170 having the embossed pattern is stamped and then switched to the SPM operation, the embossing cartridge 100 is pulled out from the body of the rough rolling mill (SPM) 200 using the rails, It is easy to use two functions. That is, the present invention can be used quickly and conveniently in two modes, SPM mode and embossing pattern stamping mode, which are originally functions of the temper rolling mill 200.

4 is a view illustrating a method of manufacturing an embossed steel sheet using an embossing cartridge according to a preferred embodiment of the present invention.

Referring to FIG. 4, an embossed steel sheet manufacturing method using the embossing cartridge of the present invention comprises the steps of: drawing an SPM roll from a body of a roughing mill 200, and then embossing the embossing work roll 110 with an embossing pattern 100) (step S101).

Then, the steel sheet 170 is rolled and then heat-treated, and the heat-treated steel sheet is passed to both side reels provided in the temper rolling mill (step S102).

Next, the oil is sprayed toward the steel plate in the mist spraying mode, and the steel plate is driven to move the steel plate so that the steel plate 170 passes between the embossing work roll 110 and the elastic roll 140 (step S103).

Then, a certain load is applied to the steel plate 170 while the steel plate 170 passes through the embossing cartridge 100, and the embossed pattern is projected and stamped on the back side of the steel plate 170 (step S104).

Then, the flatness of the steel plate 170 in the leveler is corrected (step S105).

Finally, the steel sheet 170 imprinted with the embossed pattern is pre-cut and then packaged (step S106).

The method of manufacturing the embossed steel sheet using the embossing cartridge according to the present invention can reduce the manufacturing cost by shortening the number of steps compared with the conventional method and reduce the manufacturing cost by mounting the embossing cartridge 100 on the roughing mill 200, The embossed pattern can be imprinted on the back surface of the steel plate 170 in an indirect manner rather than directly imprinting the embossed pattern on the concave portion 170,

FIG. 5 is a view showing a procedure for producing an embossing work roll in the embossing steel sheet manufacturing apparatus using the embossing cartridge according to the preferred embodiment of the present invention.

Referring to FIG. 5, in order to make the embossing work roll 110, a pattern of a desired pattern is first produced by a consumer (step S201).

Then, the surface of the work roll is subjected to polishing and acid treatment (step S202).

Then, the photosensitive liquid is evenly applied to the work roll through a whirler (step S203).

Then, a film made of the pattern pattern requested by the consumer is attached to the surface of the work roll (step S204).

Then, the pattern is left on the surface through ultraviolet exposure (step S205).

Then, the embossing work roll 110 is finished by etching (step S206).

The embossing work roll 110 manufactured in the above step is mounted on the embossing cartridge 100 so that the embossing pattern can be engraved on the steel plate 170.

Hereinafter, the method of manufacturing the embossed steel sheet and the method of manufacturing the embossed steel sheet using the embossing cartridge of the present invention will be described as follows.

Table 1 shows the primary rolling process of the conventional method.

Table 2 is a table showing the secondary rolling process of the conventional method.

In a general rolling mill, after annealing a steel sheet, a steel sheet having a hardness of Hv 180 (200 or 300 series) is subjected to a rolling reduction of 4 to 7% at a load of about 40 to 80 tons in a rolling mill, Work.

The steel plate after 9 steps in the primary rolling process has a hardness of Hv 450 ~ 500 in normal hardness. Therefore, annealing (softening heat treatment) must be performed.

The hardness of the steel sheet after one heat treatment process is about Hv 150-175, and the embossing work roll engraved with the embossing pattern pattern desired by the consumer is put into the second roll. At this time, the rolling method is carried out in the same manner as the first step, but the embossing rolling is performed only once at the final step, and the rolling load is applied at a maximum of 50 to 80 tons in order to transfer the embossed pattern pattern engraved on the embossing work roll Should be.

The finished steel sheet in the second rolling process has a hardness of Hv 250 ~ 280, and therefore, the steel sheet must be further heat treated again. At this time, if the heat treatment process is not carried out, there is a problem that the moldability is low and the possibility of bending is high and it is difficult to meet the desired hardness of the consumer. Therefore, the conventional method requires a minimum of two rolling processes and two heat treatment processes.

6, the conventional embossing steel sheet manufacturing apparatus includes an embossing work roll and a basic work roll made of the same material, and a steel sheet is sandwiched between the embossing work roll and the basic work roll, The pattern is impressed on the front face of the steel sheet by the pressure load of the embossing work roll. In this case, when the rolling speed is increased, the basic work roll serves to discharge the steel sheet. However, since there is no separate elastic force, cracks or pattern deformation may occur at the interface between the embossing work rolls contacting with the steel sheet, min You should work at low speed. Thus, there is a disadvantage in that production loss due to low-speed operation must be paid.

In addition, the rolling process in conventional processes is performed by spraying over 3,000 liters of rolling oil per minute through a rolling oil injection nozzle for the desired plasticity, high temperature cooling and surface gloss. A large amount of rolling oil of about 70,000 to 120,000 liters is stored and operated using a rolling oil storage tank and a filter system. At this time, if foreign matter or residue on the surface of the steel sheet passes through the embossing work roll, marks are generated on the embossing work roll or the basic work roll, so that the expensive work roll can not be used, Occurs.

Table 3 is a table showing the rolling process using the embossing cartridge of the present invention.

The embossing steel sheet manufacturing method using the embossing cartridge of the present invention reduces the manufacturing cost by shortening the rolling process and the heat treatment process from one rolling process to one final heat treatment process. Further, since the embossing cartridge 100 adopts a low pressure method of 15 to 30 kg, the service life of the embossing work roll 110 is long and can be easily removed when foreign matter is mixed, The defects are remarkably reduced, and the hydraulic device capable of adjusting a desired pattern is advantageously very simple.

The embossing work rolls 110 and the elastic rolls 140 made of a rubber material are provided on the upper side embossing work rolls 110 The lower side elastic roll 140 is pressed by the pressure load of the embossing work roll 110 and the pattern is projected on the back side of the elastic roll 140, Since the pattern is not deformed, the working speed can be increased to 50 m / min or more, and productivity is improved.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
