The present invention provides a forging and pressing production management method, comprising the steps of: A. acquiring at least one characteristic of a fed material; B. correspondingly selecting, according to the characteristic of the material, at least one of the temperature, the pressure or a mold from among operating factors of the forging and pressing process; C. transporting the material according to the selection result; and D. processing the material until a finished product is produced. The present invention enables at least one material to be formed by hot melt and forging and pressing by itself without human operation, thereby completing the mass production of the material. Operating factors such as the pressure, temperature and mold required for formation are taken into account, and the identification requirements for the material are reduced, thereby realizing large-scale production.

A method for manufacturing an operation rod of a wrench assembly for disassembling a fan clutch, including following steps of: preparing a rod material; fixing the rod material on a forging mold; carrying out a forging process to produce a semi-finished head; carrying out a cutout process, cutting the remainder structure out of the semi-finished head; obtaining a finished product of a head portion, the head portion including two wing plates and a shaft which are integrally formed.

A method for manufacturing a forged component includes: performing hot forging on a material; heating the hot forged material to a first set temperature; and performing warm coining to correctly shape the heated material. The material may be heated to a second set temperature before hot forging. The material heated to the second set temperature may be hot forged. The second set temperature may be higher than the first set temperature. The hot forged material may be subjected to controlled cooling to a third set temperature at a predetermined cooling rate. The controlled cooled material may be heated to the first set temperature. The third set temperature may be lower than or equal to the first set temperature.

Provided is a press forming method for a semi-solid material, including: a semi-solid material carrying step of carrying a semi-solid material into a lower die; a first press forming step of regulating, under a Z-direction regulation state in which a change in the Z direction's dimension corresponding to a pressing direction is regulated by an upper die, a change in one of the dimensions in X and Y directions by compressing the material with a transverse punch so that the one becomes equal to a dimension of the product, and then stopping the punch at a position of the compression; and a second press forming step of moving, under a state in which the change in the one is regulated in the above step, the upper die in the pressing direction to compress the material so that the Z direction's dimension becomes equal to the product's dimension.

A method of manufacturing a trailer hitch receiver tube with an integral reinforcing collar is described. A two piece die having an interior shape and dimensions conforming to the shape and dimensions of a selected trailer hitch receiver tube is provided, the two pieces of the die being a right half and a left half. Each of the right and left halves of the die are provided with means to forcefully move the die from an open position to a closed position around a workpiece. The die, around an upper edge thereof is provided with a relief cavity around its perimeter having the shape of a reinforcement collar. A base mandrel is provided between the right and left halves of the die, the base mandrel having a size and shape conforming to the size and shape of the interior of a trailer hitch receiver tube, and the base mandrel having a height less than the die. A steel receiver tube is positioned on the base mandrel, the tube having a height greater than the die halves. The die halves are then closed forcefully against the receiver tube. A forming mandrel is provided above the receiver tube. The forming mandrel has a longitudinal portion that conforms in shape to the interior of the receiver tube, and a lateral, forming portion for bearing against the upper edge of the receiver tube to form the upper portion of a receiver tube into a reinforcing collar by deforming the upper end of said tube into the relief cavity. An upper edge of the receiver tube is then forcefully struck with the forming portion of the forming mandrel, to form the collar, wherein the longitudinal portion of the forming mandrel closely approaches an upper surface of the base mandrel after the collar is formed.

Provided is a production method, including a first preforming process for obtaining a first preform from a billet, a second preforming process for obtaining a final preform from the first preform, and a finish forging process for forming the final preform into a finishing dimension of a forged crankshaft. In the first preforming process, a plurality of flat parts are formed by pressing pin-corresponding parts and journal-corresponding parts in a direction perpendicular to an axial direction of the billet. The second preforming process includes: a process of pressing regions to be a plurality of journals with a width direction of the flat part as a pressing direction by using a pair of first dies; and a process of, after starting pressing by the first dies, decentering regions to be a plurality of pins with the width direction of the flat part as a decentering direction by using second dies.

A forging device for producing a piston blank has a forging mold that has an essentially cylindrical cavity matching the radial outer surface of the piston blank, a forging base delimiting the cavity, and a central die consisting of a mandrel that has a conically tapering extension which is mounted on the mandrel and the shape of which matches the inner surface of the piston blank. In order to form the radially outer surfaces of the piston slipper walls and a peripheral cooling pocket located radially outside the slipper walls in the piston head, the forging device has two lateral jaws which are mounted in the forging device so as to be movable at an angle to the longitudinal axis of the forging device.
