Abstract
The invention relates to the technical field of machining, and discloses a manufacturing process for an aluminum alloy tooling plate for titanium rod punching. According to the manufacturing process,the aluminum alloy tooling plate is manufactured. The manufacturing process has the advantages that an aluminum alloy raw material plate is subjected to material preparation, numerical control machining and grinding machine machining to manufacture the special tooling plate suitable for titanium bar punching machining clamping, so that the problem of the blank of an existing special clamp for titanium bar punching machining can be solved, the purpose of stably clamping a titanium bar is achieved, oil stains on the tooling plate are cleared through cleaning and chemical polishing, the tooling plate is subjected to pretreatment before hard anodizing, finally, in an oxidation treatment tank with an oxidation solution composed of 5-10% sulfuric acid and 95-96% of distilled water, the direct current of 20 V-24 V, the current density of 2 A / dm<2>-2.8 A / dm<2> and the oxidation temperature of -5 DEG C-+5 DEG C, after 90 min-100 min of oxidation reaction, a layer of hard oxidation film is generated on the surface of the tooling plate, the strength, the wear resistance and the corrosion resistance of the tooling plate are improved, furthermore, the tooling plate can be recycled, and the machining cost is lowered.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a manufacturing process of an aluminum alloy tooling plate for drilling titanium rods. Background technique [0002] Titanium rod has the advantages of excellent strength, hardness, low density, light weight, high temperature resistance, low temperature resistance, good machining performance, excellent corrosion resistance, non-magnetic and five poisonous, good heat transfer performance, etc., and has memory , Superconductivity, titanium rod products are widely used, such as aerospace, navigation, automobile industry, mobile phone case production in life, computer case and spare parts production, etc. [0003] At present, during the drilling process of titanium rods, due to the high strength, high hardness and strip shape of the titanium rod itself, it can only be clamped and drilled one by one, which has low processing efficiency and high labor intensity. In the p...
