Description

Technical Field

[0001] The invention relates to the technical field of forging dies for cylindrical parts, in particular to a profiling forging method for complex cylindrical parts and a tooling die thereof. Background Art

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets to cause them to undergo plastic deformation in order to obtain forgings with certain mechanical properties, shapes, and sizes. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as as-cast porosity produced during the metal smelting process and optimize the microstructure. At the same time, because the complete metal flow lines are preserved, the mechanical properties of forgings are generally better than those of castings of the same material. For important parts with high loads and severe working conditions in related machinery, forgings are mostly used, except for simpler shapes that can be made of rolled plates, profiles, or welded parts. Complex cylindrical parts usually require the use of molds to assist in the rapid prototyping of complex cylindrical parts during forging production, so that the shape and specifications of the complex cylindrical parts meet the use requirements;

[0003] However, existing staff need to take out the forged complex cylindrical parts when forging the cylindrical parts using complex cylindrical parts forging dies. Traditional complex cylindrical parts forging dies usually adopt bottom-top discharge. Since the lower end of the complex cylindrical parts is narrower and contains less metal materials, while the upper end of the complex cylindrical parts is wider and contains more metal materials, the strength of the lower end of the complex cylindrical parts is reduced. When the traditional complex cylindrical parts forging dies adopt bottom-top discharge, the lower end of the complex cylindrical parts is easily deformed, affecting the quality of the complex cylindrical parts. Therefore, it does not meet the existing needs. In this regard, we propose a contour forging method for complex cylindrical parts and its tooling die. Summary of the invention

[0004] The purpose of the present invention is to provide a method for forging a complex cylindrical part and a tooling die thereof, so as to solve the problem raised in the above background technology that the staff needs to take out the forged complex cylindrical part after forging the cylindrical part using the complex cylindrical part forging die. The traditional complex cylindrical part forging die usually adopts the bottom top discharge. Since the lower end of the complex cylindrical part is narrower and has less metal material, and the upper end of the complex cylindrical part is wider and has more metal material, the strength of the lower end of the complex cylindrical part is reduced. Therefore, when the traditional complex cylindrical part forging die adopts the bottom top discharge, the lower end of the complex cylindrical part is easily deformed, thereby affecting the quality of the complex cylindrical part.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0031] The technical solution of the present invention aims at the problem that workers in the prior art solutions need to take out the forged complex cylindrical parts when forging the cylindrical parts is completed when using the complex cylindrical parts forging dies. The traditional complex cylindrical parts forging dies usually adopt the bottom top discharge method. Since the lower end of the complex cylindrical parts is narrower and contains less metal material, while the upper end of the complex cylindrical parts is wider and contains more metal material, the strength of the lower end of the complex cylindrical parts is reduced.
