A method for producing a forged component from a TiAl alloy is provided, in particular a turbine blade (10), in which method a blank of a TiAl alloy is provided and deformed by forging into a forged, semi-finished part (9). A usable volume is defined within the forged, semi-finished part, the usable volume corresponding to the forged component to be produced. The shape of the blank is selected such that within the usable volume of the forged, semi-finished part, the degree of deformation resulting from forging deviates by no more than 1 from a defined value.

Aluminum alloys described herein include silicon, iron, copper, manganese, magnesium, and chromium. In various implementations, the aluminum alloys also include one or more of zinc and titanium. Typically, a total amount of iron and manganese in the aluminum alloys is no less than 0.28% by weight and no greater than 0.45% by weight, and the grains in the aluminum alloys have an average grain length of no greater than 6 mm. Aluminum alloy billets can be forged for wheel production at selected temperatures.

Methods for forming fixed-cutter earth-boring drill bits include retrieving a forged steel drill bit body from an inventory of substantially identical forged steel drill bit bodies including fixed blades and junk slots between the fixed blades. Cutter pockets are formed in the blades. Nozzle holes are formed in the drill bit body to provide fluid communication from an interior of the forged steel drill bit body to the junk slots. Additional methods include forging first and second steel drill bit bodies substantially identical in shape and configuration, forming first cutter pockets in the first steel drill bit body in a first configuration, and forming second cutter pockets in the second steel drill bit body in a second, different configuration.

A wheel automatic closed die forging production line includes a sawing machine, a first transfer track, a bar heating furnace, a first manipulator, an oscillating rolling machine, a second manipulator, a primary forging hydraulic machine, an intermediate heating furnace, a third manipulator, a finish forging hydraulic machine, a wheel transfer block, a fourth manipulator, a cutting, expanding and punching hydraulic machine, a second transfer track, a spinning machine, a fifth manipulator, a third transfer track, a heat treatment furnace, a fourth transfer track, a machining unit, a sixth manipulator and a fifth finished product track, and can improve mechanical and the physical properties of the wheel product, the wheel forging effect and the yield. Aluminum and magnesium alloy wheel compression molding is realized, reducing cost, time and labor for secondary machining and reshaping, and improving production safety and efficiency.

A forging device for molten metal includes first and second die bodies that are linked by first and second power arms to move back and forth in a cavity of a die base so as to open and close a workpiece shaping space defined between first and second die faces of the first and second die bodies. When the workpiece shaping space is opened, a molten metal is poured, and then the workpiece shaping space is closed to cast a semi-finished workpiece. After that, the first and second power arms axially press and forge the semi-finished workpiece in the workpiece shaping space into a high-strength workpiece. The high-strength workpiece is shaped by casting and forging in the same process.

A method for manufacturing an insert for an aluminum piston comprises applying pressure to a composition that comprises aluminum. The composition is deformed to form the insert for aluminum piston. The insert comprises an aluminum alloy and the insert functions as a ring carrier. Disclosed herein too is an article that comprises an insert for a piston. The article is manufactured from a composition that comprises aluminum. The insert is manufactured by a process that comprises applying pressure to the composition to form the insert.

A cycle is repeated a plurality of times, which includes a forging process for placing a material to be forged in a lower die and pressing the material to be forged in this state and then separating an upper die from the material to be forged; an elevation process for lifting the material to be forged by using an elevation device to separate the material to be forged from the lower die; a rotation process for rotating the material to be forged around its center by using a rotation device; and a lowering process for placing the material to be forged rotated by the elevation device in the lower die.

A non-deforming structure of a wrench contains: a handle and at least one driving head arranged on at least one end of the handle. The handle includes an elongated body having four corners, a first length, a handle width, a handle thickness, and four elongated recesses. The handle width is 1.4 time to 2.6 time more than the handle thickness. Each elongated recess has a second length, a largest width, and a largest depth. Each of the largest width and the largest depth of each elongated recess shrinks from an intermediate portion thereof to two ends of each of the largest width and the largest depth until connects with each corner. The second length takes up at least of the first length, the largest width takes up 2/9 to 4/9 of the handle width, and the largest depth takes up 2/9 to 4/9 of the handle thickness.
