밸런스 웨이트의 제조방법 및 그에 따라 제조된 밸런스 웨이트{MANUFACTURE METHOD FOR BALANCE WEIGHT AND THEREOF PRODUCT}MANUFACTURE METHOD FOR BALANCE WEIGHT AND THEREOF PRODUCT}

본 발명은 밸런스 웨이트의 제조방법 및 그에 따라 제조된 밸런스 웨이트에 관한 것으로, 더욱 상세하게는 산업폐기물을 재활용하여 제조원가를 절감하고 환경보호에 기여할 수 있으며, 양질의 제품을 생산할 수 있는 밸런스 웨이트의 제조방법 및 그에 따라 제조된 밸런스 웨이트에 관한 것이다.The present invention relates to a method for manufacturing a balance weight and a balance weight produced accordingly, and more particularly, to reduce the production cost and contribute to environmental protection by recycling industrial waste, and to produce a balance weight that can produce high quality products. And to a balance weight produced accordingly.

일반적으로 밸런스 웨이트는 회전체의 회전시 진동을 감소시켜 안정감을 줄 수 있도록 하기 위한 것으로, 드럼 세탁기나 엘리베이터 등에 많이 사용되고 있다.In general, the balance weight is to reduce the vibration during rotation of the rotating body to give a sense of stability, and is widely used in drum washing machines or elevators.

첨부된 도 1은 일반적인 드럼 세탁기의 구조를 나타낸 단면도이다.1 is a cross-sectional view showing the structure of a general drum washing machine.

도 1에 나타낸 바와 같이, 드럼 세탁기는 캐비닛(2) 내측에 세탁물의 세정이 이루어지는 터브(4) 및 상기 터브(4) 내에서 회전되어 내부에 놓여진 세탁물의 세정작용이 이루어지는 드럼(6)이 설치되고, 상기 캐비닛(2)의 전방에는 세탁물이 상기 드럼(6) 내부로 출입되는 투입홀(h)이 형성된 캐비닛 커버(3)가 설치되고, 상기 캐비 닛 커버(3)에는 상기 드럼(6)으로부터 세탁물이 이탈되는 것을 방지하기 위해 도어(미도시)가 도어 힌지 어셈블리(미도시)에 의해 개폐 가능하게 설치된다.As shown in FIG. 1, the drum washing machine includes a tub 4 for washing laundry inside the cabinet 2 and a drum 6 for rotating laundry inside the tub 4 to perform washing of the laundry placed therein. The cabinet cover 3 is provided at the front of the cabinet 2 in which laundry is introduced into and out of the drum 6, and the cabinet 6 is provided at the drum cover 3. A door (not shown) is installed to be opened and closed by a door hinge assembly (not shown) to prevent the laundry from being separated from the laundry.

그리고, 상기 캐비닛(2)는 상측에 상기 터브(4)로 세탁수를 안내하는 급수호스(8) 및 상기 급수 호스(8)를 개폐하는 급수밸브(10)가 장착되고, 하측에 터브(4)에 채워진 세탁수를 외부로 배출시키기 위한 배수펌프(12) 및 배수호스(14)가 장착되며, 전방 상측에는 세제를 저장하는 세제통(26) 및 드럼세탁기의 작동을 제어하는 컨트롤러(미도시)가 장착된다.The cabinet 2 is equipped with a water supply hose 8 for guiding the wash water to the tub 4 and a water supply valve 10 for opening and closing the water supply hose 8 on the upper side, and a tub 4 on the lower side. Equipped with a drain pump 12 and a drain hose 14 for discharging the washing water filled in the outside to the outside, and the controller (not shown) to control the operation of the detergent container 26 and the drum washing machine to store the detergent in the front upper side Is fitted.

상기 터브(4)에는 후방에 상기 드럼(4)과 회전축(15)으로 연결되어 상기 드럼(6)을 회전시키는 모터(16)가 장착되며, 상측 및 하측에는 각각 드럼 세탁기의 탈수 행정시 발생되는 진동을 완충시키는 스프링(17) 및 댐퍼(18)가 장착되고, 상기 터브(4) 내부에 채워지는 세탁수의 온도를 조절하는 히터(20)가 장착된다.The tub 4 is equipped with a motor 16 connected to the drum 4 and the rotary shaft 15 at the rear thereof to rotate the drum 6, and the upper and lower sides of the tub 4 are generated during the dehydration stroke of the drum washing machine, respectively. A spring 17 and a damper 18 for damping vibration are mounted, and a heater 20 for controlling the temperature of the wash water filled in the tub 4 is mounted.

여기서, 상기 모터(16)는 보통 무게가 5~8㎏정도이므로 터브(4)의 무게 중심이 후방으로 편심되어 드럼세탁기의 작동시 드럼(6)의 회전이 원활하게 이루어지지 않는다. 따라서, 상기 터브(4)의 전방에는 터브(4)의 무게 불균형을 해소하기 위해 소정의 무게를 갖는 2개의 밸런스 웨이트(22)가 상하 장착된다.Here, the motor 16 is usually about 5 ~ 8kg weight, so the center of gravity of the tub 4 is eccentric to the rear does not smoothly rotate the drum (6) during the operation of the drum washing machine. Therefore, two balance weights 22 having a predetermined weight are mounted up and down in front of the tub 4 to eliminate the weight imbalance of the tub 4.

한편, 세탁/건조 드럼세탁기의 경우 상기 터브(4)의 전방에는 세정이 완료된 세탁물을 건조하기 위한 건조덕트(24) 및 응축덕트(미도시) 등이 장착되는 바, 상기 밸런스 웨이트(22)는 모터(16) 뿐만 아니라 건조덕트(22), 응축덕트 등을 고려하여 무게가 결정된다.Meanwhile, in the case of a washing / drying drum washing machine, a drying duct 24 and a condensation duct (not shown) are installed at the front of the tub 4 to dry the washed laundry. The weight is determined in consideration of not only the motor 16 but also the drying duct 22, the condensation duct, and the like.

그러나, 종래 밸런스 웨이트는 반원형이며 체결용 홀이 형성되고, 내부에 공 간을 갖도록 플라스틱으로 성형된 브로와의 내부에 콘크리트를 주입하여 양생시키는 방법으로 제조된다.However, conventional balance weights are semicircular and have fastening holes formed therein, and are manufactured by a method of curing concrete by injecting concrete into a brow formed of plastic so as to have a space therein.

그러나, 상기와 같은 종래 제조방법에 의해 제조된 밸런스 웨이트는 콘크리트에 수분이 침투하여 내구성이 약화되므로 크랙이 발생되고, 주입구를 통해 분진이 외부로 발생되는 문제점이 있었다.However, the balance weight manufactured by the conventional manufacturing method as described above has a problem that cracks are generated because moisture is penetrated by concrete and durability is weakened, and dust is generated through the injection hole to the outside.

또한, 상기 종래 제조방법은 브로와 내에 수작업으로 콘크리트를 주입하므로 작업시간이 많이 소요되고, 건조 및 경화시간이 5일 이상 소요되어 오래 걸리는 문제점이 있었다.In addition, the conventional manufacturing method takes a lot of work time because the concrete is manually injected into the broach, and the drying and curing time takes 5 days or more, there is a problem that takes a long time.

한편, 이를 개선하기 위해 제안된 종래 기술로써 플라스틱과 쇳가루를 혼합하여 성형함으로써 밸런스 웨이트를 제조하는 방법이 제안된 바 있다. On the other hand, as a conventional technique proposed to improve this has been proposed a method of manufacturing a balance weight by mixing and molding plastic and powder.

그러나, 상기 종래 제조방법으로 제조된 밸런스 웨이트는 표면에 녹이 발생되는 문제점이 있으며, 특히 1개당 제조시간이 너무 길어 생산성이 낮은 문제점이 있고, 단가도 매우 고가인 문제점이 있었다.However, the balance weight produced by the conventional manufacturing method has a problem that rust occurs on the surface, in particular, the production time per one is too long, there is a problem of low productivity, there is a problem that the unit price is also very expensive.

도 2에 나타낸 바와 같이, 본 발명의 제조방법은, 압연 및 단조스케일과 수지 접착제를 혼합하는 1단계(S1)와, 상기 혼합물을 교반시키는 2단계(S2)와, 상기 혼합물을 성형틀에 주입하고 프레스에 의해 압착시키는 3단계(S3)와, 상기 압착된 1차 성형물을 탈형시킨 후 가열 건조시키는 4단계(S4)와, 상기 건조된 1차 성형물의 외면에 외피를 코팅시키는 5단계(S5)로 구성된다.As shown in Figure 2, the production method of the present invention, the first step (S1) of mixing the rolling and forging scale and the resin adhesive, the second step (S2) of stirring the mixture, and the mixture is injected into the mold And step 3 (S3) to be pressed by a press, the step 4 and step (S4) for demolding the compressed primary molding and heat-dried, and the step 5 (S5) for coating the outer surface of the dried primary molding It is composed of

도 2 및 도 3을 참조하여 보다 상세하게 설명하면,In more detail with reference to Figures 2 and 3,

<1단계(S1)><Step 1 (S1)>

압연 및 단조공정에서 발생된 압연스케일 및 단조스케일을 수거하여 혼합하여 원료로 사용한다.The rolling scale and forging scale generated in the rolling and forging process are collected and mixed to be used as raw materials.

쇳가루의 경우 단가가 매우 고가이고, 구입하기도 어려운 문제점이 있다. 그러나 본 발명은 산업폐기물로써 처리비용이 발생되는 압연스케일을 수거하여 재활용함으로써 저렴한 비용에 원료의 구입이 가능하며 환경보호에도 기여하게 된다.In the case of kelp powder, the unit price is very expensive, and there is a problem that it is difficult to purchase. However, the present invention collects and recycles a rolling scale that generates treatment costs as industrial waste, thereby enabling the purchase of raw materials at low cost and contributing to environmental protection.

상기 압연스케일 및 단조스케일은 적절히 혼합하면 비중 3 이상을 얻을 수 있고, 이를 압착시키면 필요한 비중인 4 이상을 얻을 수 있다. When the rolling scale and the forging scale are properly mixed, specific gravity 3 or more may be obtained. When the rolling scale and forging scale are compressed, the specific gravity of 4 or more may be obtained.

압착시키기 전에 압연 및 단조스케일 입자 간의 접착력을 갖도록 하기 위해 압연스케일과 수지접착제를 혼합한다.Before pressing, the rolling scale and the resin adhesive are mixed to have an adhesive force between the rolled and forged scale particles.

바람직한 혼합비율은 압연스케일 1kg에 대해 수지접착제 90~100g를 혼합한다.The preferred mixing ratio is 90 to 100 g of the resin adhesive is mixed with respect to 1 kg of the rolling scale.

<2단계(S2)><Step 2 (S2)>

상기 압연 및 단조스케일과 수지접착제를 혼합시킨 혼합물을 드럼에 넣고 교반시킨다. The mixture obtained by mixing the rolled and forged scales with the resin adhesive is placed in a drum and stirred.

이때, 압연 및 단조스케일 입자들 간의 결합력이 강화될 수 있을 정도의 약한 온도로 가열해주면 좋다. At this time, it is good to heat to a temperature that is weak enough to enhance the binding force between the rolling and forged scale particles.

따라서, 연속적인 교반에 의해 압연 및 단조스케일의 입자들이 균일하게 수지 접착제와 혼합될 수 있다.Therefore, the rolling and forging scale particles can be uniformly mixed with the resin adhesive by continuous stirring.

<3단계(S3)><Step 3 (S3)>

상기 혼합물을 성형틀에 주입하고 프레스에 의해 압착시킨다.The mixture is poured into a mold and pressed by a press.

성형장치는 소정 형상의 홈을 갖는 성형틀과, 상기 성형틀의 상부에서 승강되는 가압대와, 상기 가압대에 가압력을 제공하는 유압펌프로 구성된다.The molding apparatus includes a molding mold having a groove having a predetermined shape, a pressurizing table which is lifted from the upper part of the forming mold, and a hydraulic pump that provides a pressing force to the pressurizing table.

따라서, 성형틀의 홈에 상기 2단계에서 배합된 혼합물을 일정량 충진시킨 후 가압대를 하강시켜 가압함으로써 1차 성형물을 제조한다.Therefore, after filling a predetermined amount of the mixture blended in the second step into the groove of the mold, the pressing unit is lowered to press the primary molded product is produced.

<4단계(S4)><Step 4 (S4)>

상기 3단계(S3)에서 제조된 1차 성형물(2)을 탈형시킨 후 가열로에서 건조시킴과 아울러 단단하게 경화시킨다.After demolding the primary molded product (2) prepared in step 3 (S3) and dried in a heating furnace and hardened.

<5단계(S5)><Step 5 (S5)>

상기 4단계(S4)에서 경화된 1차 성형물(2)은 단단하기는 하나 낙하충격시 체결용 홀부분이 취약해서 쉽게 깨지는 특성이 있다.Although the primary molded product 2 cured in the fourth step (S4) is hard, the fastening hole part is vulnerable at the time of the drop impact, so it is easily broken.

이를 보완하기 위해 1차 성형물(2)의 외면에 외피(4)를 코팅시킴으로써 충격에 견딜 수 있고, 녹 발생을 방지할 수 있다.In order to compensate for this, by coating the outer shell 4 on the outer surface of the primary molding 2, it can withstand the impact and prevent the occurrence of rust.

상기 1차 성형물(2)의 외면에 외피(4)를 코팅시키는 방법은 다양할 것이나, 본 실시예에서는 인서트 방식의 성형을 실시하였다.The method of coating the outer shell 4 on the outer surface of the primary molding 2 will be various, but in the present embodiment was performed by the insert molding.

즉, 1차 성형물(2)을 금형에 삽입하고, 상기 금형 내에 PP복합합성수지를 투입한 후 사출시키게 된다.That is, the primary molded product 2 is inserted into the mold, and the PP composite resin is injected into the mold and then injected.

바람직하게는 사출된 외피(4)의 두께는 1.3mm ~ 1.5mm가 적정하다.Preferably, the thickness of the injected shell 4 is appropriately 1.3 mm to 1.5 mm.

따라서, 인서트 사출에 의해 1차 성형물(2)과 외피(4)가 일체화될 수 있으므로, 박리될 우려가 없어 내부에서 1차 성형물(2)이 파손될 위험이 최소화될 수 있다. Therefore, since the primary molded part 2 and the outer shell 4 may be integrated by the insert injection, there is no fear of peeling, thereby minimizing the risk of breaking the primary molded part 2 therein.

상기한 제조공정에 의해 제조된 본 발명의 밸런스 웨이트(A)는 내부에 습기가 침투할 수 없는 밀폐된 구조이므로 녹이나 부식이 발생될 우려가 없고, 충격에도 강하여 내구성이 향상될 수 있다.Since the balance weight A of the present invention manufactured by the above-described manufacturing process is a sealed structure in which moisture cannot penetrate inside, there is no fear of rust or corrosion, and it is also resistant to impact, thereby improving durability.

비록 본 발명이 상기 언급된 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 청구의 범위에 속함은 자명하다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, all such modifications and modifications being attached It is obvious that the claims belong to the claims.
