Rotary press die
11358201 · 2022-06-14 · ·

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°.

Tools, machines, and methods for machining planar workpieces

A tool for machining a planar workpiece, comprising an upper tool having a clamping shaft and an upper main body that lie on a common positioning axis, a tool body arranged opposite to the clamping shaft on the upper main body, the tool body comprising a bending edge, and a lower tool having a lower main body that receives a rotational body that is rotatable around an axis of rotation running in a direction of the bending edge of the tool body, wherein the upper tool and the lower tool are movable towards and away from each other in a stroke direction for machining the workpiece arranged therebetween, and wherein the upper main body defines a projection surface that is perpendicular to the positioning axis and the bending edge of the tool body is adjacent tangentially to the projection surface or is outside the projection surface.

Rotary slide with cooling and temperature-controlled zones

A device for a press for shaping a sheet metal part with a section which can be shaped out separately as an undercut in the device. The device includes a press-side ram, a swage and a die which can be driven separately, serves to shape out the undercut, and interacts with an undercut contour which is arranged substantially in a filler slide which is mounted such that it can be moved rotationally in the swage. The filler slide can be transferred from a shaping-out position into a position which exposes the undercut in the sheet metal part, and vice versa. At least one temperature-control device is provided in the filler slide, by way of which temperature-control device the filler slide can be temperature-controlled at least in sections.

Rotary bending devices

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.
