摘要： The present invention aims with respect to a negative-angle forming die with a lower die half supporting a rotary cam and an upper die half having an intrusion forming portion cooperating with an intrusion forming portion of the rotary cam upon a descend of the upper die half to form a sheet metal product to avoid the problem that the work (W) is damaged by interference of the rotary cam (5) with portions of the work (W) protruding in a direction extending across the rotation axis during retraction of the rotary cam (5) after the intrusion forming. The rotary cam (5) is divided into at least an end rotary cam section (5 1 ) and a main rotary cam section (5 2 ), both of the divided rotary cam sections (5 1 , 5 2 ) being disposed on the same pivoting axis (L), and the end rotary cam section (5 1 ) being provided with means for restricting the end rotary cam section (5 1 ) from pivoting for a predetermined period of the pivoting during retraction of the rotary cam after the forming operation, and for axially moving the end rotary cam section (5 1 ) relative to the main rotary cam section (5 2 ) for a predetermined period of the pivoting during retraction of the rotary cam after the forming operation.

摘要： The present invention aims with respect to a negative-angle forming die having an air cylinder as retractor for a rotary cam to eliminate the need for the timing adjustment of the air cylinder operation at the time of pressing operation and to simplify the piping necessary for the air cylinder. The invention provides a negative-angle forming die comprising a lower die half (1) with an intrusion forming portion inward of a downward stroke line of an upper die half (3). A slide cam operated by the descending upper die half includes an intrusion forming portion and is slidably opposed to a rotary cam (5), wherein a sheet metal work placed on the lower die half is formed by the cooperation of the intrusion forming portions of the rotary cam and of the slide cam. The rotary cam (5) is rotatably supported in the lower die half (1) via supporting shafts (11) respectively projecting from the ends of the rotary cam. An automatic retractor is provided in the lower die half (1) for pivoting the rotary cam (5) back to a position where the work can be taken out of the lower die half (1) after the forming operation. A rotary cam driving apparatus comprises a cam follower arm (52) fastened with a center portion to one of the supporting shafts (11) of the rotary-cam (5), an end of the cam follower arm (52) is connected to a piston rod (57) of a cylinder (51) provided in the lower die half (1), and another end of the cam follower arm (52) is contacted with a driver means (53) provided on the upper die half (3).

摘要： The present application aims with respect to a negative-angle forming die with a lower die half (1) supporting a rotary cam (5) and an upper die half (3) having an intrusion forming portion cooperating with an intrusion forming portion (4) of the rotary cam upon a descend of the upper die half to form a sheet metal product (W) to avoid the problem that slight pivoting movement makes the rotary cam move slightly out of a predetermined forming position, thereby creating an unwanted step in a curved surface of the work or making it impossible to form the work into an accurate contour, particularly if accuracy in the order of 1/100mm is required. The present application aims to maintain the rotary cam at a predetermined forming position during the forming process in that the rotary cam (5) is provided with a receiving portion (31), a lock bar (34) having an engaging portion (33) for engagement with the receiving portion (31) is slidably disposed in the vicinity of the rotary cam (5) and the lock bar (34) is urged by a means (35) for providing a returning urging force in a direction such that said engaging portion (33) is out of engagement with the receiving portion (31). The slide cam (5) is provided with means (72,73) for providing an urging force on the lock bar (34) which is larger than that provided by the returning urging force providing means (35) in the direction such that the engaging portion (33) gets into engagement with the receiving portion (31) of the rotary cam (5) at the time of the intrusion forming performed by the slide cam (8) and the rotary cam (5).
