A rotary press die has a rotating die forming a negative angle part on a plate-like work and a fixed die arranged outside the rotating die and forming a molding part except for the negative angle part on the work. The rotating die is a press molding die which is formed such that the press molding die rotates about a rotating axis when the work is removed and can be retracted inside the fixed die. A rotating block is configured by a fixed piece arranged on the fixing table and having a concave slide surface having the rotating axis as a center. A moving piece is arranged on the rotating die and having a convex slide surface which can slide on the concave slide surface by using the rotating axis as a center. An opening angle between the concave slide surface and the convex slide surface is 80° to 100°.

An automatic production equipment includes a strip-material feeding device set, a continual stamping die set and a rivet providing mechanism. The strip-material feeding device set feeds a strip material. The continual stamping die set includes a upper stamping die group and a lower stamping die group. The lower stamping die group includes a lower die plate, a strip receiving groove formed on the lower die plate for receiving the strip material, a sliding block slidable on the strip receiving groove, and a guide groove formed on the sliding block to connect to the strip receiving groove. The upper stamping die group includes an upper clamping plate, a pushing lever and a riveting punch. The pushing lever and the riveting punch are located on the upper clamping plate. The rivet providing mechanism is connected to the sliding block, and feeds rivets into the guide groove in order.

A composite automatic production equipment for in-mold placement process includes a upper stamping mold having a upper die plate and punches, a lower stamping mold having a lower die plate, a punching strip feeding device sending out a punching material strip to the lower stamping mold, an insulating-sheet feeding device feeding out an insulating-film material strip intersecting to the punching material strip. The insulating-film material strip includes a main material strip and insulating sheet sets that are adhesive and detachably arranged along the main material strip. When the upper and lower die plates are closed, the punches punch the punching material strip to form semi-finished products arranged in sequence, and one of the semi-finished products is pressed to adhere to one of the insulating sheet sets. When they are separated, the insulating sheet set on the semi-finished product is torn off from the insulating-film material strip.

An electrostatic oiling system for use with single blanks in batch systems having an open spray chamber without the need for a negative vacuum chamber. Further, the provided electrostatic oiling system may utilize induction beams and a charge wall that allows for utilization of a smaller vacuum system. Further, the provided electrostatic oiling system may provide variable blank coverage without the need for metered pumps.
