Abstract
The utility model discloses a cast steel piston top which comprises an inner cavity which is arranged in the center, a cooling cavity which encircles the inner cavity, and a plurality of reinforcing ribs which are evenly distributed in the cooling cavity. Two ends of each reinforcing rib are respectively connected with two side walls of the cooling cavity. Due to the fact that the plurality of the reinforcing ribs are arranged between the two side walls of the cooling cavity. Under the circumstance that outer wall thickness of the piston top is not increased because of the structure, strength and toughness of the outer wall of the piston top are effectively increased, and materials are saved, weight is reduced and cost is reduced. Meanwhile, steel top distortion which is caused by internal stress because of nonuniform wall thickness by casting is overcome.
Description
Technical field
The utility model relates to a kind of cast-steel piston top.
Background technique
The advantage on cast-steel piston top is that casting cooling inner chamber can save " car inner chamber " this cumbersome manufacturing procedure, has so just greatly saved the mach time.But also there is the lower shortcoming of strength and toughness of outer wall in the cast-steel piston top, and casting can cause the piston top wall unevenness even in addition, and the even internal stress of bringing of wall unevenness can cause the distortion of steel top.Although present existing problem can solve by the wall thickness that increases piston top, this method but can increase the weight of material consumption and piston top, and cost of production also can increase thereupon.
The model utility content
Technical problem to be solved in the utility model provides a kind of intensity height, good toughness, lightweight, cast-steel piston top that cost is low.
In order to solve the problems of the technologies described above, technological scheme provided by the utility model is: a kind of cast-steel piston top comprises the inner chamber at the center of being arranged at, around the cooling chamber of inner chamber and be evenly distributed on several stiffening ribs in the cooling chamber; The two ends of described stiffening rib are fixedly connected with the two side of cooling chamber respectively.
Be provided with cavity between the bottom surface of described stiffening rib and cooling chamber.
After having adopted technique scheme, the utlity model has following beneficial effect: (1) the utility model arranges several stiffening ribs between the two side of cooling chamber, this structure is in the situation that does not increase the piston top wall thickness, effectively increased the strength and toughness of piston top outer wall, reached economical with materials, weight reduction, the effect of reduction cost can also overcome the steel top distortion that causes the even internal stress of bringing of wall unevenness to cause because of casting simultaneously.
(2) be provided with cavity between the bottom surface of stiffening rib of the present utility model and cooling chamber, this structure has promoted cooling effect so that whole cooling chamber is connected as a single entity.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.

Embodiment
(embodiment 1)
See Fig. 1 and Fig. 2, the cast-steel piston of present embodiment top comprises the inner chamber 1 at the center of being arranged at, around the cooling chamber 2 of inner chamber 1 and be evenly distributed on several stiffening ribs 3 in the cooling chamber 2.
The two ends of stiffening rib 3 are fixedly connected with the two side of cooling chamber 2 respectively.Be provided with cavity 4 between the bottom surface of described stiffening rib 3 and cooling chamber 2.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
