Abstract

The invention discloses an electrophoresis pretreatment process for vehicle parts. The electrophoresis pretreatment process comprises the following steps in sequence: hot water washing, pre-greasing, greasing, primary water washing, surface conditioning, phosphorization, secondary water washing and purified water washing, wherein the secondary water washing step adopts a mode in which dipping is combined with spraying of a discharging bath, so that the removal effect of a residual phosphorization bath solution on a work piece is effectively removed; meanwhile, excluding the secondary water washing step, all the other steps adopt a dipping treatment mode on the premise of satisfying the technological quality requirements, so that the operation and maintenance difficulty and cost of technological equipment are effectively reduced, the technological implementation process is simple and easy to implement, and the treatment efficiency is relatively high.

Description

technical field [0001] The invention relates to the technical field of motor vehicle parts processing, in particular to a pre-electrophoresis treatment process for motor vehicle parts. Background technique [0002] In recent years, the automobile manufacturing industry has developed rapidly. While the production and sales volume has continued to rise, people have put forward higher quality requirements for the coating performance and corrosion resistance of automobile-related parts. Pre-treatment is a part of the electrophoretic coating process and an important link that affects the quality of the coating. In order to meet the high-standard manufacturing requirements of auto parts, people put forward higher requirements for the pre-treatment process technology. [0003] At present, there are three kinds of treatment methods widely used in the actual production and processing process of electrophoresis pretreatment process: dipping treatment method, spraying treatment method ...
