摘要： A rotary bending device for bending workpiece includes a saddle, a rocker, and first and second alignment elements. The saddle includes a longitudinally extending cavity in which the rocker is received, and the rocker rotates relative to the saddle between a neutral position and a bending position for bending the workpiece. The first alignment element is provided on the rocker, and the second alignment element is positioned to engage the first alignment element to limit axial movement of the rocker relative to the saddle during rotation of the rocker between the neutral position and the bending position. The rocker may tangentially contact a bearing surface of the cavity at no more than two lines of tangential contact during rotation. The rocker may further include a longitudinally extending shoulder, and the device may further include a return element positioned to contact the shoulder for biasing the rocker toward the neutral position.

摘要： A filler cam assembly for use with a forming die generally including a center cam component, end cam components and a base assembly and being designed to transition between unloading and forming positions. The various cam components preferably have axial ends with helical surfaces such that rotation of one of the cam components causes a corresponding axial movement of an adjacent cam component. Some features of the filler cam assembly include removable work steels, standardized cam components, drive and lock out mechanisms, and being able to form negative angles, multiple corners and edges, and an entire formable periphery of a metal work piece in a single forming operation, to name but a few.

摘要： The present invention provides a bending die in which the fixed die 1 and the rotary die 2 are surface contacted to each other, the rotary die 2 is rotated rearward after press forming to cause the workpiece 3 to be moved away from the die, wherein the contact surface 9 between the fixed die 1 and the rotary die 2 is formed in a flat surface. In addition, the present invention is set such that the rotary center point P of the rotary die 2 is set outside the line 10 drawn from one end C1 of the linear line indicating the contact surface 9 of the rotary die 2 in a direction of right angle in respect to the linear line when the contact surface 9 is seen in a section of a direction perpendicular to the axis of the rotary die 2. With such an arrangement as above, a machining of the contact surface 9 can be facilitated more and under a lower cost than those as compared with those forming the arcuate surface as found in the prior art.

摘要： The present invention aims to simplify the negative-angle forming die as much as possible thereby reducing price, and at the same time aims to improve accuracy thereby making possible to provide a high-quality sheet-metal formed product. The present invention provides a rotary cam moving apparatus for a negative-angle forming die comprising a lower die half having a supporting portion for placing a sheet metal work, and an upper die half to be lowered straightly downward onto the lower die half for forming the work, an intrusion forming portion formed in the lower die half at an edge portion near the supporting portion inward of a downward stroke line of the upper die half, a rotary cam rotatably provided in the lower die half, a slide cam including an intrusion forming portion and slidably opposed to the rotary cam, and an automatic retractor provided in the lower die half for pivoting the rotary cam back to a position thereby allowing the work to be taken out of the lower die half after a forming operation, the work placed on the supporting portion of the lower die half being formed by the intrusion forming portion of the rotary cam and the intrusion forming portion of the slide cam, the slide cam forming the work by sliding, the automatic retractor pivoting back the rotary cam after the forming operation for allowing the work to be taken out of the lower die half, wherein a flange is formed at an end portion of the work in a direction across an axis of the pivoting, the work then undergoing an intrusion formation, the flange at the end portion of the work being protected from damage caused by retraction of the rotary cam, by dividing the rotary cam into an end rotary cam for placing the flange formed at the end portion of the work and the main rotary cam for the other portion, both of the divided rotary cams being disposed on a same axis of pivoting, the end rotary cam not being pivoted for an initial predetermined period of the retraction, thereafter the end rotary cam being moved axially toward the main rotary cam.

摘要： A press-forming die set including a first die and a second die which are linearly movable in a press-forming direction for mutual engagement to form a negative-angle portion on a workpiece placed on the second die, the press-forming die further including a rotary cam having a first negative-angle forming portion, and a forming cam having a second negative-angle forming portion. The first negative-angle forming portion is disposed such that the rotary cam is rotatable about an axis of rotation inclined with respect to a bottom surface of the workpiece. The rotary cam is engageable with the second die and is rotated about the axis of rotation in one of opposite directions when the first and second dies are moved toward each other, and is rotated in the other direction when the first and second dies are moved away from each other. The forming cam is held in engagement with the first negative-angle forming portion while the first and second dies are held in engagement with each other, and is disengaged from the first negative-angle forming portion when the first and second dies are spaced apart from each other.

摘要： This invention is comprised of a lower die having a groove-like cavity formed at its upper surface; a rotary die supported in the cavity of the lower die at both ends thereof by a shaft and rotatably stored in it; an upper die arranged above the rotary die; and a driving device for rotating said rotary die in a downward direction after the upper die is opened and for retracting it. The cavity is formed with some protrusion steps at its inner circumferential surface for use in supporting the rotary die when pressed. The rotary die is formed with a forming part for gathering and bending a metallic plate at its upper surface to be extended in a longitudinal direction of the rotary die. The gathering and bending blade to be fitted to the forming part of the rotary die is formed at the upper die. In the case of the present invention, the aforesaid rotary die is supported at the protrusion steps when pressed while the outer edge of the forming part is being abutted against the upper edge of the lower die and after pressing operation, it is rotated in a downward direction by the driving device.
