Description
Technical field
The present invention relates to a kind of gun stock base member, especially a kind of for the gun stock seat on panzer.
Background technology
Existing infantry's panzer front end is generally all provided with rotating machine gun, facilitates multi-angle to attack enemy.In existing various Vehicle De L'Avant Blinde By Creussot, the moving-coil of its gun stock seat ring and the general employing of fixed circle all-steel, the in-built steel ball of gun stock seat ring raceway, therefore its weight is very large, is unfavorable for the light activity of panzer and year moving payload.In the light wheel armoured vehicle of development, for alleviating vehicle body deadweight, the moving-coil of gun stock seat ring and fixed circle start to adopt the technical scheme of all aluminium alloy, the in-built nylon ball of gun stock seat ring raceway in the back.But in actual applications, the gun stock seat ring raceway in this scheme and the equal serious wear of nylon ball, gun stock race components is difficult to meet the requirements of service life, has a strong impact on use and the maintenance of panzer.
Gun stock seat ring adopted again the technical scheme of the casting of aluminium alloy edge steel bushing, the in-built steel ball of gun stock seat ring raceway afterwards.Because the thermal coefficient of expansion difference of aluminium alloy and steel is larger, in practical application, in the time of casting, cause that stress is concentrated, easily cause moving, the fixed circle of aluminium alloy and peeling off of steel bushing, especially in the situation that circumstance of temperature difference changes greatly, moving, the fixed circle circle of aluminium alloy will be peeled away completely with steel bushing, causes gun stock to lose efficacy.
By information retrieval, there is following known prior art scheme:
1, Li Fengyi etc. is at " development of cast iron/aluminium alloy compound castingin piston " (" casting " .1966,45-46 page) in a literary composition, announce a kind of method of cast iron/aluminium alloy compound castingin, but it operates the restriction complexity to material, need " pre-aluminising processing ", imbedding process complexity, the performance requirement of material is high, and the production cycle is long.
2, Chinese Patent Application No.: 201210014076.0, the applying date: 2012-01-17, Granted publication day 2013-08-28, a kind of aluminum alloy-clad cast iron liner compound material and preparation technology thereof are announced, first by HT250 Cast iron liner in Rare-Earth Ce, hot-dip in the fused solution of Pr and ZL 101 alloy, at 700～800 ℃ of hot-dip time 5-10 minute, HT250 Cast iron liner is taken out and is fixed in the die cavity of metal mold casting die, with Medium Frequency Induction Heating Furnace melting ZL 101 alloy and rare earth element ce, rare earth element Pr fused solution is built, complete whole casting cycle.The present invention is by rational surface pre-treating process and add two kinds of metallic surface tension force of rare earth element reduction, improve wetability, realized the metallurgical binding of ZL 101 alloy and two kinds of metals of HT250 cast iron by casting method, have more than 98% metallurgical binding face, method is with low cost, and technique is simple.On its basis above, increased in addition rare earth element, commercial Application cost is high, long flow path.
