Description

마찰 압접기 및 마찰 압접 방법{FRICTION WELDING APPARATUS AND FRICTION WELDING METHOD}FRICTION WELDING APPARATUS AND FRICTION WELDING METHOD}

본 발명은 가공물끼리 마찰 압접하기 위한 마찰 압접기 및 이것을 이용한 마찰 압접 방법에 관한 것이며, 특히 외경(外徑)이 상이한 가공물 간이나 길이가 긴(長尺) 가공물 간의 마찰 압접 및 기계 가공의 연속화에 적합하다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a friction welding machine for friction welding between workpieces and a friction welding method using the same, and particularly, to continuous friction welding and machining between workpieces having different outer diameters or long workpieces. Suitable.

가공물끼리의 접합면에 회전 마찰력을 발생시키고, 이 회전 마찰로 발생한 열 에너지를 이용하여, 가압, 고상압접합(固相壓接合)하는 마찰 압접법이 공지되어 있다(특허문헌 1).The friction welding method which pressurizes and solid-phase-pressure-bonds using the thermal energy which generate | occur | produces a rotational friction force on the joining surface of workpieces, and uses this thermal friction is known (patent document 1).

이러한 마찰 압접법에 있어서, 높은 접합 강도를 얻으려면 접합면의 품질이 중요하며, 또한 접합면이 발열에 의해 연화 상태로 된 가공물끼리 업세팅 추력(upsetting thrust)에 의해 가압하므로, 전체 길이의 치수 변화나 접합부에 발생하기 쉬운 버(burr)도 고려할 필요가 있다(특허문헌 2).In this friction welding method, in order to obtain a high bond strength, the quality of the joint surface is important, and also the workpieces are pressed by upsetting thrust between workpieces that are softened by heat generation, so that the overall length is measured. It is also necessary to consider the burr which is easy to generate | occur | produce a change and a junction part (patent document 2).

한편, 예를 들면 도 4(a)에 나타낸 바와 같이, 플랜지부(W1)를 가지는 길이가 긴 제품을 가공하는 경우에 플랜지부의 분기 부분의 가공에는, 스핀들(146)에, 돌출된 길이가 긴 블레이드(147)를 부착하여 가공하게 되는데, 블레이드 선단에 진동이 발생하기 쉬워, 가공 정밀도가 저하하는 문제가 있다.On the other hand, for example, as shown in Fig. 4A, in the case of processing a long product having the flange portion W1, the length of the protruding portion of the spindle portion 146 is used to process the branch portion of the flange portion. Although the long blade 147 is attached and processed, there is a problem that vibration is liable to occur at the tip of the blade and the machining precision is lowered.

따라서, 이러한 제품의 경우에 플랜지부(W1)와 샤프트부(W2)를 별도로 가공하고, 그 후에 W1와 W2를 마찰 압접하는 방법이 유효하지만, 종래는 가공기와는 상이한 별도의 마찰 압접기에 각각 가공물을 척킹하여 마찰 압접하고 있었기 때문에, 예를 들면 도 4(c)에 나타낸 바와 같이 플랜지부(W1)의 단면을 가공할 때에, 가공물이 척 지그(chuck jig)로부터 일단 분리되어 있기 때문에, 다시 회전 방향의 위상 결정을 해야만 하는 문제가 있었다.Therefore, in the case of such a product, the method of separately processing the flange portion W1 and the shaft portion W2, and then friction welding the W1 and W2 is effective, but in the prior art each of the workpieces in a separate friction welding machine different from the machine Since the workpiece was separated from the chuck jig when the end face of the flange portion W1 was processed, for example, as shown in FIG. There was a problem that the phase determination of the direction had to be made.
