Further, Fig. 4 illustrates manufacturing of kitchen utensils according to another embodiment of the present invention, in which a strip is inserted into a 4- way roller to manufacture a knife, Fig. 5 illustrates manufacturing of kitchen utensils according to another embodiment of the present invention, in which a knife is manufactured by use of a 4-way roller, Fig. 6 is a fragmented view taken in the direction of the arrows along the line A-A of Fig. 5, Fig. 7 illustrates manufacturing of kitchen utensils according to another embodiment of the present invention, in which a rod wire is manufactured by use of a 4-way roller, and Fig. 8 is a fragmented view taken in the direction of the arrows along the line A-A of Fig. 7.
According to an embodiment of the present invention, a plurality of fine and thin strips 10 are firstly processed, and annealed in order to soften their structure, improving their plasticity, as shown in Figs. 1 and 2.
The resulting strips are then rapidly subjected to a rolling process. In details, the resulting strips are inserted between an upper and a lower roller, and a predetermined shape such as a knife, a chopstick, a power drill, or a pin is engraved in each roller.
In more details, a plurality of strips are inserted between the upper and lower roller, positioned opposite from each other, rotating by driving shafts (not shown in drawings) to form the initial shape of a kitchen utensil such as a knife, a chopstick, a power drill, or a pin, thereby being subjected to a preliminarily forming step 100. Thereafter, the strips are moved between an upper and a lower roller of a firstly processing step 102 to form a predetermined shape of kitchen utensils.
The kitchen utensils subjected to the firstly processing step 102 are then annealed to improve the plasticity of the kitchen utensils 103.
Subsequently, the strips subjected to the firstly processing step 102 and the annealing step 103 are moved between an upper and a lower roller of a secondly processing step, and moved between another upper and another lower roller having predetermined pattern to engrave the pattern on a grip of the resulting kitchen utensils, according to a pattern forming step 106, thereby accomplishing the resulting kitchen utensils 108.
In the present invention, in particular, manufacturing of a knife is exemplified.
With reference to Fig. 2, a plurality of strips 10 are rolled by upper rollers 12, 16, 20, and 24 and lower rollers 14, 18, 22, and 26 according to a preliminarily forming step 100, a firstly processing step 102, a secondly processing step 104, and a pattern forming step 106.
In the preliminarily forming step 100, the upper and lower roller 12 and 14 are oppositely positioned while rotating, and a predetermined shape 15 is engraved in the upper and lower roller 12 and 14, thus forming the predetermined shape 15 of kitchen utensils.
The upper and lower roller 12 and 14 are distant from each other by a predetermined gap Gl .
The gap is slightly thicker than a final kitchen utensil product. In the firstly processing step 102, an upper and a lower roller 16 and 18 are positioned opposite from each other while rotating, and a predetermined shape 19 is engraved in the upper and lower roller 16 and 18, thus forming the predetermined shape 19 of kitchen utensils.
The upper and lower roller 16 and 18 are distant from each other by a predetermined gap G2.
The strip 10 is processed by the rollers only during one rotation of the upper and lower rollers.
The gap G2 has the same thickness as the final kitchen utensil product.
After the firstly processing step, the strip is annealed by heating devices 21 positioned over and under the strip to improve the plasticity of the strip.
The strip softened by the heating devices 21 is subjected to the secondly processing step 104.
In the secondly processing step 104, an upper and a lower roller 20 and 22 are oppositely positioned while rotating, and a predetermined shape 23 is engraved in the upper and lower rollers 20 and 22, thus forming the predetermined shape 23 of kitchen utensils.
Furthermore, in the pattern forming step 106, an upper and a lower roller 24 and 26 are positioned opposite from each other while rotating, and a predetermined pattern 27 is engraved in the upper and lower roller 24 and 26, thus forming the predetermined pattern 27 on a grip of kitchen utensils.
As described above, the strip is processed by the upper and lower rollers 12, 14, 16, 18, 20, 22, 24, and 26 to manufacture the resulting kitchen utensil product 108.
The above method of manufacturing kitchen utensils, according to an embodiment of the present invention is advantageous in that manufacturing time of the kitchen utensils is reduced, and manufacturing effectiveness of the kitchen utensils is improved because of reduced manpower time, hence volume.
Fig. 3 illustrates manufacturing of kitchen utensils according to another embodiment of the present invention, in which a continuously wound strip steel sheet is used instead of an individual strip 10 as shown in Fig. 2. In the same manner as the primary embodiment of Figs. 1 and 2, the strip steel sheet in the embodiment of Fig. 3 is moved between the upper and lower roller and processed to manufacture the desired kitchen utensils.
Meanwhile, the strip subjected to the firstly processing step 102 is annealed to improve the plasticity of the strip. At this time, the strip is heated to a predetermined temperature by heating devices 103 positioned over and under the strip. After that, the process shown in Fig. 2 is repeated.
Turning now to Figs. 4 to 6, an upper and a lower roller 12 and 14 are positioned opposite from each other, and a strip 10 is moved between the upper and lower rollers 12 and 14.
At this time, the left and right rollers 28 and 30 are rotated by a driving shaft (not shown in drawings) operating by a motor (not shown in drawings) are separately positioned on the left and right of the strip. The left and right rollers 28 and 30 process the strip while rotating in conjunction with the upper and lower rollers 12 and 14, and a predetermined shape is engraved in the left and right rollers 28 and 30, thus forming the predetermined shape of kitchen utensils.
The process using a 4-way roller shown in Fig. 4 is the same as that shown in Fig. 3, thus not being separately described.
Fig. 6 is a fragmentary view taken in the direction of the arrows along the line A-A of Fig. 5. Predetermined shapes 15 are formed in the left and right rollers 28 and 30 as well as in the upper and lower rollers 12 and 14, and the strip is moved by the above rotating rollers 12, 14, 28, and 30.
Fig. 7 illustrates manufacturing of kitchen utensils according to another embodiment of the present invention, in which a rod wire with a desired diameter is manufactured by use of a 4-way roller.
Referring to Fig. 7, a method of manufacturing the rod wire comprises the steps of preliminarily forming the rod wire with an initial diameter by passing an annealed strip or coil through a four-way roller, firstly processing the preliminarily formed rod wire so as to reduce its diameter; secondly processing the firstly processed rod wire in order to give a predetermined diameter to the rod wire; and thirdly processing the secondly processed rod wire in order to give a desired diameter of 1.0 mm or less to the rod wire.
As described above, the strip 10 is gradually reduced in a diameter by the 4-way roller to obtain the strip with a desired diameter. Therefore, a rolling process of manufacturing the kitchen utensils conducted by the 4-way roller is advantageous in that an upper and a lower die are supported by the left and right roller 32 to precisely, stably, and effectively form products.
Fig. 8 is a fragmentary view taken in the direction of the arrows along the line A-A of Fig. 7, in which an upper and a lower roller 12 and 14 and a left and a right roller 42 and 44 each have circular arc shapes 17 and 19 so as to form a cylindrical rod wire.
The rod wire is processed using the upper and lower roller and the left and right roller according to the same procedure as Fig. 1. In comparison with a conventional drawing process, the rolling process of the present invention is advantageous in that a friction coefficient is dispersed, a smooth products having a desired illuminance and structure can be manufactured because a roll oil is inserted between products and a roller to rapidly cool the products, and a roller can be semi-permanently utilized. Furthermore, the rolling process has the advantages to reduce manufacturing time, to produce excellent manufacturing effectiveness, to decrease personnel expenses, and to improve product quality because the rod wire is processed using a continuous wire drawing machine with 3 or 4 blocks in the rolling process while the rod wire is processed using the continuous wire drawing machine with 8 blocks in a wire drawing process. In the case of rolling process, a diameter of the rod wire can be reduced to from 5.5 mm to 1.0 mm with the use of the continuous wire drawing machine with 4 blocks in a wet manner, while the diameter is just reduced to from 5.5 mm to 2 mm with the use of the continuous wire drawing machine with 8 blocks in a wet manner in the case of the wire drawing process.
