Embodiment Construction

[0018] A metal casting and forging method and casting and forging equipment according to preferred embodiments of the present invention will be described below with reference to related drawings, wherein the same elements will be described with the same reference symbols.

[0019] figure 1 For a flow chart of the steps of a method for casting and forging metal parts according to an embodiment of the present invention, please refer to figure 1 shown. A method for casting and forging metal parts in this embodiment may include the following steps: placing metal raw materials into a trough of a die-casting mold, and the metal raw materials form a molten state in the trough (S10); forming the mold and the die-casting mold closing each other to form an accommodating space (S20); injecting the molten metal raw material from the trough into the accommodating space (S30); cooling the molten metal raw material to form a first metal piece (S40); The metal part and the forming die are c...

Abstract

The invention discloses a casting and forging method of metal piece. The casting and forging method comprises the following steps of putting a metal raw material in a material-placing groove of a die-casting mold, the metal raw material forming a melt state in the material-placing groove; closing a forming mold and the die-casting mold to form an accommodate space; pouring the metal raw material in the melt state into the accommodate space from the material-placing groove; cooling the metal raw material in the melt state to form a first metal piece; placing the first metal piece and the forming mold in a forging mold accordingly; and forging the first metal piece in the forming mold by the forging mold to form a second metal piece. The invention also discloses a casting and forging apparatus of the metal piece. With the casting and forging method and the apparatus, an effect that can be achieved by forging five times with a known forging technology can be achieved in one forging time; tedious processes can be simplified; process time is shortened; and the metal piece has high strength and precision. Moreover, due to the the design of transferring the forming mold together with the first metal piece into the forging mold without replacing the forming mold, a processing reference point can be can further fixed.

Description

technical field [0001] The present invention relates to a metal forming method. Background technique [0002] The common forming methods of metal parts can be divided into die casting forming and forging forming. Among them, die-casting is formed under high pressure, so that liquid or semi-liquid metal is filled into the die-casting mold at a high speed, and formed and solidified under pressure to obtain metal castings. The process is time-consuming and can form a three-dimensional structure through the design of the mold. However, due to the fast filling speed of the liquid metal into the mold, the liquid metal cannot be filled into the mold stably, so that the molded metal casting is likely to have pores, and secondary processing must be performed. In addition, the shrinkage of the formed metal casting is relatively serious, so usually a large processing space must be reserved, and the strength and precision of the formed metal casting are poor. [0003] In addition, fo...
