다른형 띠부재의 제조법Manufacturing method of other band member

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명이 실시예에 의한 제조방치의 설명도.1 is an explanatory diagram of a manufacturing apparatus according to an embodiment of the present invention.

제2A도는 본 발명에 의한 실시예 펀치의 평면도.2A is a plan view of an embodiment punch according to the present invention.

제2B도는 그 측면도.2B is a side view thereof.

제2C도는 그 입면도.2C is an elevation view.

제2D도는 A-A' 단면도.2D is a cross-sectional view along the line A-A '.

제3A도는 피가공재의 프레스 가공중의 상황을 도시한 설명도.3A is an explanatory diagram showing a situation during press working of a workpiece.

제3B도는 프레스 가공중의 피가공재의 각 단면도.3B is a cross-sectional view of the workpiece during press working.

Claims (2)

측면의 일부에 경사면을 가진 가로로 봉형인 펀치를 사용하고 평면형 띠부재의 표면을 부분적으로 다른형상으로 프레스 가공하는데 있어서, 피가공재를 일정한 방향으로 이동시키면서 펀치의 가로방향을 그 부재의 이동방향에 대하여 직각보다 작은 각도로 유지한 상태에서 펀치를 피가공재에 반복하여 가압 하강하여 가공함으로써 그 부재에 두께가 다른 부분을 가지는 단면을 얻는 것을 특징으로하는 다른형 띠부재의 제조법.In the use of a horizontally punched punch with an inclined surface on a part of the side and partly press-forming the surface of the flat strip member, the transverse direction of the punch is shifted to the moving direction of the member while the workpiece is moved in a constant direction. A method for producing another band member, characterized in that a cross section having a portion having a different thickness is obtained by repeatedly pressing and punching the workpiece to a workpiece while the angle is kept smaller than the right angle. 제1항에 있어서, 상기 펀치의 가로 방향을 상기 피가공재의 이동간에 변동시킴으로써 그 부재의 프레스 가공된 두께가 다른 부분의 가로폭을 변화시키는 것을 특징으로하는 다른형 띠부재의 제조법.The method of manufacturing the other strip member according to claim 1, wherein the width of the pressed part of the member is varied by varying the width of the punched portion in the transverse direction between the movements of the workpiece. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
