Research on the processing technology of small car component bolts
The main mold design features a pre-formed head with a rounded pier. A cross-shaped exhaust groove is integrated into the right end face of the front core, and corresponding grooves are also formed around the circumference. This allows accumulated air to flow smoothly through the grooves, effectively eliminating air entrapment and significantly reducing quality issues. These improvements have played a crucial role in enhancing the flow of the material and improving the surface finish of the product's end face. Additionally, a vent hole has been added at the center of the convex mold cavity, which helps prevent air gaps from forming between the bottom of the mold and the workpiece's red ridge during forging. This feature is particularly important in eliminating surface scars at the head end of the part. The work position die incorporates a front guide mold that serves a dual purpose: it acts as both a reduced-diameter leading mold and a pre-forming mold for the head. The entire process and tooling have been implemented in mass production and have yielded highly satisfactory results. After the head is rounded into a spherical shape in the working position, the station directly performs the forging operation, resulting in a smooth, scar-free end face. There are no pits or other defects, and the surface roughness is well-controlled. Forged products exhibit straight grain structures, clear thread blanks, stable dimensions, and minimal taper in the billet. The contour of the cone at the intersection of the two rods is clearly defined, with excellent dimensional accuracy, surface finish, and overall appearance. These improvements have led to significant cost reductions and enhanced product quality, contributing to notable economic benefits for our plant. By refining the forging process, we have not only improved efficiency but also ensured consistent and high-quality output, making our production more competitive in the market.
