A manufacturing process of automobile insert damping block

Abstract

The invention relates to a manufacturing technique for car insert damping blocks. The manufacturing technique comprises the following steps that produced-in-advance stainless steel framework pieces for the damping blocks and with the material model being 301 are taken for later use; grease dirt of the surfaces of the stainless steel framework pieces for the damping blocks are removed; the stainless steel framework pieces for the damping blocks are subjected to activating treatment; the activated stainless steel framework pieces for the damping blocks are placed into a drying oven to be dried; the stainless steel framework pieces for the damping blocks are heated in a vacuum furnace under the oxygen environment; the stainless steel framework pieces for the damping blocks are subjected to closing treatment; the stainless steel framework pieces for the damping blocks are dried; sulfuration is conducted; and cutting is conducted. Through the manufacturing technique, the surfaces of obtained good-color-and-lustre stainless steel framework unit plates are each provided with a golden oxidation film, corrosion resistance is excellent, the tensile strength is large, and the Vickers hardness is high; damping rubber blocks are high in hardness, large in tensile strength and high in elongation; after high-temperature ageing is conducted at the temperature of 90 DEG C for 94 h, change of the hardness is small, and the elongation is large; heat resistance is high; and stainless steel damping block units meet the requirement that the damping rubber blocks are not bounced off from the stainless steel framework unit plates under the effect of 20 N.

Description

technical field

[0001] The invention relates to a manufacturing process of an automobile insert damping block, which belongs to the technical field of automobile parts manufacturing technology. Background technique

[0002] At present, the research on stainless steel coloring is mainly chemical coloring method and electrochemical coloring method, both of which can get bright stainless steel, but chemical coloring method generally uses chromic acid and sulfuric acid solution as the coloring solution, and high concentration chromic acid is easy to volatilize during the coloring process, which is harmful to the environment. and the human body cause great harm, while the electrochemical coloring solution still uses chromic acid and sulfuric acid solutions; and some small and medium-sized enterprises cannot afford expensive equipment;

[0003] Vulcanization molding can only produce one product at a time, and the product will have flashes, which cannot be punched. Silicone and sta...
