Abstract

PURPOSE: A knob manufacturing method for cold forging and machining is provided to improve the quality of a product by accurately forming a handle with zinc and separately assembling a screw unit. CONSTITUTION: A knob manufacturing method for cold forging and machining comprises the following steps: cold forging the knob(1); machining the knob(2); forming a screw unit on the knob(3); and plating the knob(4). The cold forging step is performed at a temperature under 250 deg C. The knob is manufactured using a heading machine and an exclusive cutting machine.

Description

냉간 단조 및 절삭가공병행 손잡이 볼트(노브) 제조방법{Knob manufacturing method in parallel cold heading and cutting}  Knob manufacturing method in parallel cold heading and cutting

본 발명은 냉간단조와 절삭가공을 병행하여 생산성 향상 및 제조원가 절감을 위한The present invention is a combination of cold forging and cutting to improve productivity and reduce manufacturing costs

제조 공법이다. It is a manufacturing method.

도 1과같이 손잡이 볼트 제조방법은 요철부분이 있어 수량이 적은 경우 절삭가공을 하며 수량이 많은 경우 정밀주조 방법으로 제조하였으나 이를 냉간단조 후 As shown in Fig. 1, the manufacturing method of the handle bolt has an uneven portion, so when the quantity is small, the cutting process is performed, and when the quantity is large, it is manufactured by the precision casting method.

요철부분을 절삭가공 함으로써 제조원가 절감 및 생산성 향상을 기할 수 있다. By cutting the uneven parts, it is possible to reduce manufacturing cost and improve productivity.

정밀주조(다이캐스팅)에 의한 제조 방법은 아연으로 손잡이 부분을 정밀주조하고 나사부를 별도로 만들어 조립하여 생산함으로 생산비용이 높다.    The manufacturing method by precision casting (die casting) has high production cost by precision casting the handle part with zinc and assembling and producing the screw part separately.

단조공정으로 손잡이 볼트를 만들고 오목부분을 절삭가공함으로써 정밀주조(다이캐스팅)에 의한 제조 방법의 단점을 개선하여 생산원가 절감 및 대량생산이 가능함 By making the handle bolt in the forging process and cutting the recessed part, it is possible to reduce the production cost and mass production by improving the disadvantages of the manufacturing method by precision casting (die casting).

생산원가 절감 및 품질향상    Cost reduction and quality improvement

도 2 와 같이 소재를 절단하여 단조방법으로 두부 및 볼트 몸체를 만들고 다음은 벤치레스등 전용기로 오목부분을 절삭가공하고 마지막으로 나사 부를 롤링하여 제조한다. To cut the material as shown in Figure 2 to make the head and bolt body by the forging method, and then cut the recessed portion with a dedicated benches and the like, and finally manufactured by rolling the screw.

도 1의 1과같이 준비된 소재를 절단한다.The prepared material is cut as shown in FIG. 1.

도 1의 2와 같이 절단한 소재를 1차 단조하여 중간재를 만들고,1 forging the cut material as shown in 2 of 1 to make an intermediate material,

도 1의 3과 같이 중간재를 단조 가공하여 두부(머리)를 형성한다.As shown in Figure 3, the intermediate material is forged to form a head (head).

도 1의 4와 같이 형성된 두부 주의를 절삭가공한다.Head treatment formed as shown in 4 of FIG. 1 is cut.
