Title: Forming method for channel type parts
Inventor: TAKAGI MICHIO
IPC: B21D19/08
Filed: 1990-01-30
Abstract: PURPOSE:To easily improve the strength of a parts by turn bending a flange in width direction on the press forming method of a channel type parts having flanges and both closed ends. CONSTITUTION:By properly executing a shape design of products, a tendency of spring back is constricted forcibly. The spring back of side wall is reduced by turn bending back the flange to width direction. By setting a slit type opening 30 on a arbitrarily longitudinal direction on the base part 34 of the channel type parts, a resistance against a deflection i.e. the rigidity decreases, so the spring back of the side wall is also decreased. Further, when these two modes are utilized in combination, the more effective forming method can be realized. Therefore, the high tention steel plate with strong spring back tendency can be easily used, and the strength of parts can be improved.
