Abstract

The invention discloses a production process for a hydraulic suspension damper. The method comprises the following steps of 1, stamping, wherein roll materials are put into a stamping die, a hydraulic suspension is fixed on a fixing mechanism of a punching machine for position fixation, and a driving punch of a driving mechanism is utilized to conduct stamping on the hydraulic suspension; 2, trimming and polishing, wherein trimming treatment is conducted on the stamped hydraulic suspension, and then the surface of the hydraulic suspension is polished to be smooth; 3, aluminum casting, wherein the temperature of a resistance aluminum melting furnace is set to 600-800 DEG C, heating is conducted for 20-30 minutes at first, pure aluminum is added into the resistance aluminum melting furnace to be completely melted, the hydraulic suspension treated in the step 2 is placed into the stamping die, a hydraulic aluminum casting machine is turned on to conduct aluminum casting operation on the hydraulic suspension, and after the aluminum casting operation is finished, the aluminum-casted hydraulic suspension is detected. The production process is perfect, the production efficiency is high, the damping effect is good, and it is ensured that the hydraulic suspension damper is high in quality, stable in performance and long in service life.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a production process of a hydraulic suspension shock absorber. Background technique [0002] Mounts are used to reduce and control the transmission of engine vibration and play a supporting role in automotive powertrains.
