Production method of hybrid vehicle swing arm casting

Abstract

The invention discloses a method for producing a swing arm casting of a hybrid electric vehicle. The method comprises the following steps: mixing recyclable sand, yellow sand, red sand, red pulverized coal, pottery clay, sodium carbonate, pulverized coal and water through a sand mixer; molding through a molding machine, and pouring through a balling bag by using molten iron; and after pouring is finished, performing cooling and knockout, removing broken iron blocks, arbor and core sand on a casting mold, grinding by virtue of a grinding machine, detecting and packaging to obtain the swing arm casting of the hybrid electric vehicle. The swing arm casting of the hybrid electric vehicle meets the basic requirements of five elements of Q10 cast iron, and is high in air permeability, so that the tension strength of the product is improved; the swing arm casting can be continuously molded and automatically produced by using the molding machine, so that the production efficiency and quality of the swing arm casting are greatly improved, the production link is simplified, the labor cost can be reduced, the energy consumption and the material consumption are reduced, and the comprehensive cost is reduced; meanwhile, the elongation and hardness of the product are improved, so that the product performance can be improved to the greatest extent.

Description

technical field [0001] The invention relates to a production method of an automobile swing arm casting with a tensile function, in particular to a production method of a hybrid electric automobile swing arm casting. Background technique [0002] The energy-saving and low-emission characteristics of hybrid vehicles have attracted great attention from the automotive industry, and have become a focus of automotive research and development, and the swing arm is an important casting of hybrid vehicles. It is the guide and support of the suspension. Its deformation affects the wheel alignment and reduces the driving stability; Master the direction. Therefore, the largest user of the swing arm casting industry is the automobile industry, followed by machinery, electrical equipment, metal molds, etc. With the development of the hybrid vehicle industry and technological progress, customers have higher and higher requirements for swing arm castings. At present, the hybrid vehicle sw...

AI Technical Summary

Problems solved by technology

At present, the hybrid vehicle swing arm castings on the market cannot meet the current use requirements, mainly in: 1. The tensile strength is weak and the guiding effect is poor; 2. The elongation is small, easy to deform and poor stability; 3. Low hardness , easy to break, the swing arm support effect is poor, the service life is greatly reduced, and the safety of the car is seriously affected
