Along with developing of automobile industry, the operating mode of engine trends towards high pressure, improves at a high speed.Piston to one of engine heart part also has more and more higher requirement.When keeping the conventional aluminum alloy material, improving aluminum alloy materials by surface treatment is a kind of very important means in the performance under the engine behaviour.
At the problem of engine consumption, many designs have been done improvement to structure of piston, have improved the position of the first road annular groove, increase the piston ring cause and the adhesion problems of piston ring groove but equally also derived because of top pressure.Move under the situation of engine with higher specified property parameter and low overhead height, the temperature of the first road annular groove will be greater than 250 ℃.This temperature can cause the trickle weldering company of generation between the annular groove side and the first road annular groove, and especially new engine more is easy to generate.Till today, first annular groove that solves best protection measure that trickle weldering connects and be piston carries out anodic oxidation.In the first road annular groove, carry out anodic oxidation and can improve wear resistance and protective, also improved the thermal load of annular groove simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of piston ring groove hard anodic oxidation device, this device can be realized the anodic oxidation of piston ring groove small area more exactly, greatly reduce the anodised cost of piston ring groove, and can not influence the actual use and the performance of piston because of the variation of anode region, and the anode surface that comes out by this device oxidation is evenly attractive in appearance, has improved the exterior quality of piston greatly.
Of the present utility model being characterised in that: a kind of piston ring groove hard anodic oxidation device, comprise that top has the oxidation container of being inverted piston installation port, described piston crown is provided with first annular groove, second annular groove and the 3rd annular groove and top land, the second ring bank and the 3rd ring bank, it is characterized in that: be provided with ring bank sealing-ring between perimembranous and the piston second ring bank on the described port, buckled the head seal lid on the described piston termination, be folded with the head grommet type seals between described head seal lid and the top land, the potted line of described head grommet type seals and top land to the zone between the potted line that encircles the bank sealing-ring and the second ring bank is an oxide regions, between described ring bank sealing-ring and head grommet type seals and the head seal lid annular space of going into oxide regions in order to the oxidation hydrorrhea is set.
Above-mentioned the 3rd annular groove and the 3rd ring are provided with the compacting ring that is used for clamp ring bank sealing-ring on the bank.
Be loaded with sulphuric acid soln in the above-mentioned oxidation container.
Advantage of the present utility model: the one, this piston ring groove hard anodic oxidation device simple in structure, the processing and fabricating cost is cheap, and general interchangeability is strong, helps reducing the input of business equipment fund, improves economic benefit of enterprises; The 2nd, can effectively reduce the anodised cost of piston ring groove, anode region is attractive in appearance simultaneously, has promoted the exterior quality of piston greatly.
