Forging process for automobile part blank and forging equipment thereof

Abstract

The invention discloses forging equipment for an automobile part blank. The forging equipment for the automobile part blank comprises a top plate, an upper die holder, an upper die plate, a lower die plate, a lower die holder and a lower bottom plate, wherein the lower die holder with the lower die plate is fixed onto the lower bottom plate; the lower die plate is matched with the upper die plate; the upper die plate is connected with the top plate through the upper die holder; a hydraulic driving device for driving the top plate to reciprocate up and down and a buffering and damping base are arranged at the end part of the top plate; and the buffering and damping base is fixedly arranged at the bottom of the lower bottom plate and plays a role in supporting the lower bottom plate.

Description

technical field [0001] The invention belongs to the field of forging technology, in particular to a forging process and forging equipment for blanks of auto parts. Background technique [0002] Auto parts forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes, and is one of the two major components of forging, forging and stamping. Forging can eliminate defects such as as-cast porosity produced in the metal smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than castings of the same material. For important parts with high loads and severe working conditions in related machinery, forgings are mostly used, except for plates, profiles or weldments that can be rolled with simpler shapes. However, most forg...

Problems solved by technology

However, most forging equipment directly use springs to absorb the vibration force generated during die-casting. The direct setting of springs is prone to distortion due to the long-term stretching process and excessive die-casting force, that is, the spring in the center of the spring protrudes. Here If the situation continues to press down, the spring will be damaged and can no longer be used, and the spring's absorption effect on vibration is not good, and it is easy to affect the overall quality of the forging and the loosening of parts in the forming equipment.
