Abstract

The invention discloses a machining method for a high-strength automobile ECM support. The machining method includes the following operation steps that firstly, the ECM support obtained after die releasing is put into degreasing fluid to be soaked for 5 min to 7 min and then is taken out, and the surface is cleaned; secondly, the cleaned ECM support is put into coloring liquid, the to-be-treated ECM support serves as a cathode, and a saturated calomel electrode serves as an anode; and thirdly, the ECM support obtained after electrolytic coloring is put into boiling water to be boiled for 10 min to 15 min, alkali type lead silico-chromate is added into the boiling water, the weight of the alkali type lead silico-chromate is 0.05-0.07 time of that of the boiling water, a boiling water bath is conducted continuously for 30 min to 35 min, and then the high-strength automobile ECM support is manufactured. By the adoption of the method, the manufactured ECM support is smooth in surface and superior in corrosion resistance and oxidization resistance, in addition, the strength is high, the service life is long, and an automobile ECM part can be stably supported for a long time.

Description

technical field [0001] The invention belongs to a processing method for an automobile ECM bracket, in particular to a processing method for an automobile ECM bracket. Background technique [0002] The engine electronic control module (ECM for short) has the function of continuously monitoring and controlling the normal operation of the engine. In modern engine management system, ECM is its core control element. It can provide the engine with the best air-fuel ratio mixture and the best ignition time according to the different working conditions of the engine, so that the engine is always in the best working condition, and the performance of the engine (power, economy, emission) reaches the best good. In order to make the ECM work stably for a long time, the bracket needs to have high strength and oxidation resistance, so some metal alloy materials are often used to make the automotive ECM bracket, but the alloy material needs to undergo a series of surface treatments befor...
