Abstract: Disclosed is a negative-angle forming die. The die has upper and lower halves. The upper die half has a supporting portion for receiving a sheet metal work, and an intrusion forming portion. The lower die half carries a plate-like cam which can be moved toward the lower die half for forming the work. The die also has a rotary cam, the ends of which terminate in first and second shafts journaled in the lower die half. The die also has a slide cam, which itself has an intrusion forming portion. This portion is slidably opposed to the rotary cam. The die is equipped with a cam follower arm centrally fastened to the supporting shaft. One end of the cam follower arm carries a cam follower in operable relationship with the plate-like cam carried by the upper die half. In operation moving contact between the plate-like cam and the cam follower causes the cam follower arm to rotate. This in turn causes rotation of the rotary cam. When the work is placed on the supporting portion of the lower die half, it is formed by the intrusion forming portion of the rotary cam and the intrusion forming portion of the slide cam.

Abstract: The movable blank-holder of a bending press includes a series of segments and a pair of motor-driven carriages each of which has an entraining member which can selectively engage and release the segments in order to move them for re-arrangement purposes. Each of two segments situated at opposite ends of the series includes a shoe-holder which supports a respective shoe by means of inclined guides. Each shoe-holder body carries a respective slide having a driving portion and each shoe has a driven portion. These driving and driven portions have facing cooperating pressure and sliding faces arranged in a manner such that a movement of the slide towards the center of the press is converted into an oblique movement of the respective shoe such that it is released from a lateral channel-shaped bend already formed in a metal sheet, without sliding on the sheet. Each carriage includes an entraining member and each slide includes an entrained member which can be engaged by the entraining member in order to move the slide selectively towards the center of the press. The two carriages are movable simultaneously in opposite directions upon command in order to simultaneously bring about the aforementioned movements of the shoes, by means of the slides, in directions such as to release them from the respective lateral bends. The shoes have respective resilient mechanisms for biasing them in directions to return each shoe to a working position to which it is moved away from the center of the press and from the movable blank-holder.

Abstract: A hydromechanical drive for a metal part forming machine includes an electric motor having a rotary output shaft, a drive shaft attached to the rotary output shaft and adapted to undergo rotational motion therewith about a rotational axis defined by the drive shaft, and a motion conversion mechanism coupled with the drive shaft and being movable between expanded and retracted positions along the drive shaft in response to the rotational movement of the drive shaft. The motion conversion mechanism has a first coupling element stationarily disposed at a fixed location offset from one side of the drive shaft and a second coupling element movably disposed at another location offset from another side of the drive shaft being angularly displaced from the one side thereof. The second coupling element is interconnected with a piston of a hydraulic transmitter of the forming machine such that movement of the motion conversion mechanism between the expanded and retracted positions along the drive shaft in response to rotation of the drive shaft about the rotational axis causes movement of the second coupling element toward and away from the fixed first coupling element and movement therewith of the remainder of the motion conversion mechanism, except for the fixed first coupling element, as well as movement of electric motor, drive shaft and the piston of the hydraulic transmitter connected to the second coupling element along a generally linear reciprocatory path extending in a generally orthogonal relationship to the rotational axis of the drive shaft.
