New energy automobile bearing pedestal and manufacturing process thereof

Abstract

The invention discloses a new energy automobile bearing pedestal which comprises a shell. An inner cavity of the shell is sequentially provided with a first cylindrical cavity, a second cylindrical cavity and an upper sealing cover upwards from the end face of the shell, and the inner diameter of the first cylindrical cavity is larger than the inner diameter of the second cylindrical cavity; the part, between the shell end face and the shell upper sealing cover, of the shell outer wall is sequentially provided with a first outer round wall, a second outer round wall and a connecting block arranged on the second outer round wall, and the outer diameter of the first outer round wall is larger than the outer diameter of the second outer round wall; and the shell is of an overall structure andis formed by forging of an aluminum alloy. Metal streamline of the new energy automobile bearing pedestal cannot be cut off, the grain structure is compact, the mechanical property is high, the turning machining amount is greatly reduced due to forging molding, deformation is avoided in the machining process, the product accuracy is high, the material using rate is high, the production period isshort, efficiency is high, and the automobile part mating requirement can be met.

Description

technical field [0001] The invention relates to press forming technology, in particular to a manufacturing process and an extrusion die for a bearing seat of a new energy vehicle. Background technique [0002] The new energy vehicle bearing seat plays the role of fixing the bearing and carrying the moving load of the shaft. Existing production process: direct turning of 4032 round aluminum alloy material, low material utilization rate, waste of raw materials, low production efficiency, loose internal structure, metal streamlines are cut off during turning, poor mechanical properties, difficult to meet new energy requirements Supporting quality requirements for auto parts. Contents of the invention [0003] The invention provides a forging-formed new energy automobile bearing seat structure, the metal streamline of the new energy automobile bearing seat is not cut off, the grain structure is dense, and the mechanical performance is high. Due to forging and forming, the amo...
