Description
Technical field
The utility model belongs to casting technology field, relates in particular to tubing inserts in a kind of die castingCleaning, Rustproofing apparatus.
Background technology
Developing rapidly of auto industry, has higher requirement to the Design and manufacture of part, high collectionOne-tenth, high-performance, low cost are the trend of future development. Based on withstand voltage, heat-resisting, wear-resisting the wanting of productAsk, in aluminum alloy die casting, be bumped into iron or steel part and have very large for the serviceability that promotes aluminium alloyEffect, as inlayed Cast iron liner in cylinder body, improve heat-resisting, wearability; Thermostat, oil sump can be inlayedEnter steel pipe and improve withstand voltage properties etc. Taking the withstand voltage properties of oil duct in pack alloy product as example, conventionallyDetected pressures is 400KPa left and right, but in order further to improve the performance of product, oil duct detected pressures increasesBe added to 620Kpa, this internal soundness to product requires very high, the extrusion process of existing aluminium alloy andQuality cannot ensure. Therefore, one of solution is to adopt placing steel tubes inserts in die casting to doMethod ensures withstand voltage properties and the sealing property of high-pressure oil duct, but brings again the cleaning of steel pipe inserts and preventRust problem. Although use stainless steel inserts can remove these worries from, the consideration of cost and its machinedDifficulty do not allow again to carry out such selection. Although employing electroplating technology can be antirust, reducedThe wetability of steel pipe and aluminium liquid, after part forming, the combination between aluminium and steel pipe is bad, therebyHave influence on the use of foundry goods.
If only steel tube surface is carried out to electroplating processes, again because the shape restriction of steel pipe is difficult to realize, because ofThis can only be antirust by coating antirust oil, but before die casting, steel pipe need to toast preheating, press casting procedure is highTemperature loses antirust oil, and steel pipe inner chamber loses protection, gets rusty easily. In addition after product processing, produceThe residual cutting fluid of product surface meeting, aluminium bits and other impurity, have a strong impact on product and use function, and produceProduct have cleannes requirement, as die casting product residue thing weight≤7mg, high-pressure oil duct residue weightAmount≤3mg, need to clean to ensure the cleannes of product and high-pressure oil duct.
Because the antirust oil of steel pipe inserts surface of internal cavity loses in press casting procedure, product is in operation weekIn turning, get rusty very soon, no matter and employing fountain cleans or Ultrasonic Cleaning all can only clean up productProduct outer surface position, and steel pipe inner chamber rusty stain can not clean removal, and due to contact water, furtherAggravate to get rusty in pipe. Therefore be necessary to develop a kind of new cleaning, rust cleaning, Rustproofing apparatus, to carryHigh cleaning, rust cleaning, antirust quality and efficiency.
