A clamping device has an actuator that moves linearly and is actuated by a drive. A pivoting clamping element is operatively connected, via a toggle lever mechanism, with the actuator. The toggle lever mechanism includes a drive-side adapter and a hand lever-side adapter. The drive side adapter and hand lever side adapter can be adjusted relative to one another to define an opening angle of the clamping element. One of the adapters has a profiled bar extending in a direction of actuation. The other adapter has an insertion region to accommodate the bar. A fixing element is provided in one of the adaptors to define the location of the adapters relative to one another. The fixing element can be clamped against the profiled bar and also against an insertion region.

To provide a method for producing a tire vulcanizing mold capable of obtaining a tire vulcanizing mold having excellent durability and high precision at low cost and to provide such a tire vulcanizing mold, the method includes producing a tire vulcanizing mold by assembling a pattern molding segment, produced by rapid prototyping, on a metal base segment, the method further includes a step of producing the pattern molding segment from a metal based on a shape of a surface layer part including a pattern shaping surface in a basic model of the tire vulcanizing mold.

A tool for forming a shaped product has a support body that is fabricated from a first material, such as for instance cast iron. The first material defines a first portion of a forming surface of the tool and has a feature supported thereon. The feature has a layer of a second material that is supported on the first material of the support body, a layer of a third material that is supported on the layer of the second material and a layer of a fourth material that is supported on the layer of the third material. The layer of the fourth material, such as for instance a tool steel alloy, defines a second portion of the forming surface of the tool. During use the first portion of the forming surface and the second portion of the forming surface cooperate to form a desired shape of the shaped product.

A part formed by additive manufacturing includes a plurality of layers including a first layer and a second layer, the first layer and the second layer being stacked along a stacking direction, and a work surface formed on an upper surface of the first layer and an upper surface of the second layer. The part also includes a first through-hole formed in the first layer, a second through-hole formed in the second layer, the second through-hole being at least partially aligned with the first through-hole, and a wall extending from the first through-hole to the work surface.

Forging dies are formed from a plurality of layers stacked together to form an assembly, or laminate. Each respective layer may be cut to form a portion of a die cavity, and the layers may be stacked together such that the cut portions are aligned to form the die cavity. The layers are fastened together to form a first die half and/or a second die half of disclosed forging dies. Each layer may be selectively removable from the die half for maintenance and/or replacement. Disclosed forging dies may be formed of lower grade materials as compared to conventional forging dies, and the number and thickness of layers may be varied to accommodate the specific part geometry of the part being forged. Related methods of making said forging dies and using said forging dies to make parts are also disclosed.

A system for additive manufacturing of a three-dimensional object, comprising: a controller for identifying a set of planar cross-sectional shapes of the three-dimensional object, the set extending in a sequence from a first end of the three-dimensional object to a second end of the three-dimensional object; a three-dimensional scanner, associated with the controller, configured to scan a prototype of the three-dimensional object to generate a computer-aided design model; at least one cutting station for cutting at least one barbed metal sheet into a plurality of individual planar barbed metal pieces corresponding to the cross-sectional shapes; and for cutting at least one substrate sheet into a plurality of individual planar substrate pieces corresponding to the cross-sectional shapes, wherein the at least one substrate is penetrable by the barbs; and a binding station for receiving and pressing the individual barbed metal pieces and the individual substrate pieces together.
