A die includes a die body and a removable shell. The die body includes a supply flow channel formed inside the die body. One end of the supply flow channel opens at the surface of the die body. The supply flow channel is to be supplied with a fluid for temperature adjustment. The removable shell is mounted removably to the surface of the die body. The removable shell includes an outer surface that constitutes at least a part of the forming surface of the die. A temperature adjustment space is provided in the surface of the die body or in the removable shell. The temperature adjustment space is in communication with the supply flow channel. The removable shell is divided into a plurality of shell pieces. The plurality of shell pieces are arranged in a direction intersecting the longitudinal direction of the die on the surface of the die body.

Disclosed are an external, numerically controlled, rapid reconfigurable surface mold and forming method thereof In this mold, an external shape-adjusting component is composed of a height-regulating rod, a motor, and a sliding guide rail module. The height-regulating rod is connected to the sliding guide rail module, and the motor is coaxially connected to the height-regulating rod. In addition, the molding module consists of a plurality of basic body units with the same structure, the lower end of the basic body unit is installed in the mold box, the upper end of the basic body unit is matched with the lower end of the height-regulating rod, and the height of the basic body unit is adjustable. Subsequently, in the forming method, driven by the motor and under the action of the force of the lower end of the height-regulating rod, the height-regulating rod moves above the basic body units.

An object of the present invention is to provide a bending die that has a simple configuration and is capable of bending a rod-shaped body in a three-dimensional XYZ direction quickly and reliably, the bending die comprising a pair of forming dies clamped in a Z direction, wherein the forming dies have, respectively, rod-shaped body-forming recess portions, and rod-shaped body guide portions for guiding a rod-shaped body to the rod-shaped body-forming recess portions, the rod-shaped body-forming recess portions are each formed into a shape with a semicircular cross section that defines, between the forming dies when clamping the forming dies, a long, cylindrical cavity for forming the rod-shaped body bent in a three-dimensional XYZ direction, and the rod-shaped body guide portions are each formed into a V-shape that spreads outward from both sides of each of the rod-shaped body-forming recess portions having a semicircular cross section.

A die assembly for forming finished parts from blanks includes an upper die section and a lower die section. The upper die section includes an upper segmented die having a plurality of upper die segments releasably coupled to each other. The lower die section includes a lower segmented die having a plurality of lower die segments releasably coupled to each other. The die assembly is usable with a movable gantry press configured to move to a location of the die assembly and operate the die assembly.

A modular tooling die for an axle housing includes a plurality of separable and coaxially aligned die sets. Each die set may include a cam driver that is engageable with first and second cam slide assemblies. The cam slide assemblies move toward one another along an axis that extends perpendicularly to an axis along which the cam driver translates. Multiple die sets are provided for possible use in a single press depending on the particular axle housing geometry to be manufactured. A wide variety of different geometrical configurations may be formed by simply replacing one or more die sets and inserting a differently sized or shaped blank within the press. A method of manufacturing various axle housings and the associated modular tooling is described.

The present invention discloses a forming device for a large thin-walled part with a curved surface, which includes a punch, a blank holder, a die, a lower die plate, a first annular sleeve and second annular sleeves. The first annular sleeve is connected with first driving oil cylinders. An inner diameter of the die is greater than an outer diameter of the punch. The first annular sleeve is arranged in a gap between the punch and the die. The second annular sleeve is arranged at the bottom of the punch. The first annular sleeve is arranged outside the second annular sleeve. The second annular sleeve is connected with second driving oil cylinders. The first driving oil cylinders and the second driving oil cylinders are connected with a hydraulic system.

A hot-forming press (100) comprises a lower press assembly (102) and an upper press assembly (108). The lower press assembly (102) is movable along a vertical axis and comprises a lower die (106), and a lower hot-box portion (104), configured to receive the lower die (106). The upper press assembly (108) is movable along the vertical axis above the lower press assembly (102) and comprises an upper die (112), and an upper hot-box portion (110). The upper hot-box portion (110) is configured to receive the upper die (112) so that the upper die (112) is positioned opposite the lower die (106). The lower die (106) and the upper die (112) are configured to apply a forming pressure to a workpiece (114) that is received between the lower die (106) and the upper die (112). The lower hot-box portion (104) and the upper hot-box portion (110) are configured to heat the workpiece (114).

A hybrid stamping system for forming a work-piece includes a stamping press. The press includes first and second dies that have respective first and second die bases formed from a first material. The system also includes first and second inlays. Each inlay is formed from a second material and has opposing die and work-piece sides. The second material hardness is greater than the first material hardness. The die side of the first inlay is cast into the first base and the work-piece side of the first inlay is contoured to form one side of the work-piece. The die side of the second inlay is cast into the second base and the work-piece side of the second inlay is contoured to form another side of the work-piece. The first and second dies are mounted in the press opposite one another to form the work-piece between the first and second inlays.
