High-precision forging die suitable for deep hole machining

Abstract

The invention belongs to the technical field of forging dies, and particularly relates to a high-precision forging die suitable for deep hole machining. The high-precision forging die comprises a lower bottom plate, an upper bottom plate, a discharging plate, an upper die plate, elastic air cylinders, a lower die assembly and a punch assembly, wherein the upper bottom plate and the lower bottom plate are slidably connected; the discharging plate is connected to the lower portion of the upper bottom plate through a set of elastic air cylinders; the upper die plate is fixed to the lower end faceof the discharging plate; and the lower die assembly is fixed to the lower bottom plate and corresponds to the upper die plate up and down, the upper die plate can cover the lower die assembly to form a closed die cavity, and a punch hole is reserved in the center of the upper die plate. The punch assembly comprises an upper base plate, a protective block and a punch, wherein the upper base plateis fixed to the lower end face of the upper bottom plate, and the punch vertically penetrates through the protective block downwards and is fixed to the lower end face of the upper base plate throughthe protective block. According to the high-precision forging die suitable for deep hole machining, deep hole forging can be conducted on a shaft workpiece, the forging precision is high, the overallstrength of a product is high, and the subsequent machining workload and machining cost are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of forging dies, and in particular relates to a high-precision forging die suitable for deep hole processing. Background technique [0002] In the prior art, conventional forging equipment and techniques can only use partial forging for inner hole processing of shaft parts with small and deep inner holes, such as figure 1 As shown, the forging of the inner hole part is made up by machining. Not only is the process complicated and the cost is high, but it is also not conducive to improving the overall strength and precision of the product. Therefore, it is of great practical significance to design a mold capable of forging deep holes for such parts. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a high-precision forging die suitable for deep hole machining. [0004] In order to achieve the above object, the present invention is achieved through the ...
