Abstract
The utility model relates to a centrifugally-cast one-into-two cylinder sleeve blank body, and belongs to the technical field of manufacturing of cylinder sleeve blank bodies of engines. The centrifugally-cast one-into-two cylinder sleeve blank body comprises a cylinder sleeve blank body and a through hole; the through hole is formed in the center of the cylinder sleeve blank body; small-diameter circular rings are arranged at two ends of the cylinder sleeve blank body; large-diameter circular rings and medium-diameter circular rings are arranged in the middle of the cylinder sleeve blank body; the length of the cylinder sleeve blank body is 356 mm; the diameter of the through hole is 65 mm; the sizes of the small-diameter circular rings are 117 mm; and the sizes of the large-diameter circular rings are 125 mm. The centrifugally-cast one-into-two cylinder sleeve blank body can cast at least two cylinder sleeve blank components at a time, and is small in machining allowance, high in machining qualified rate and low in manufacturing cost and saves raw materials; and the problems that the conventional cylinder sleeve blank bodies are all slightly tapered hollow columns, only a single blank component can be manufactured, the machining allowance is large, the machining qualified rate is low and the machining and manufacturing cost of a producing enterprise is increased are solved.
Description
Technical field
The utility model relates to all two cylinder toison base substrates of a kind of centrifugal pressure casting, belongs to air cylinder sleeve of engine blank system technology for making field.
Background technique
Air cylinder sleeve of engine is one of most crucial component of motor, when the liner blank system is made all is to adopt centrifugal pressure casting, and existing cylinder liner blank body is because the release problems when considering centrifugal pressure casting; The structure of liner blank body all is one to have a little the tapering hollow cylinder; And can only make by single blank, the machining allowance of blank body is big, and passing rate of processing is low; Not only waste raw material, and increase the manufacturing cost of manufacturing enterprise.
Summary of the invention
The purpose of the utility model is, provides a kind of machining allowance of blank body little, reduces the raw material of blank body, and rational in infrastructure, machining allowance is little, all two cylinder toison base substrates of the centrifugal pressure casting that passing rate of processing is high.
The utility model is to realize above-mentioned purpose through following technological scheme:
All two cylinder toison base substrates of this centrifugal pressure casting are made up of cylinder liner blank body and through hole; It is characterized in that: the center of cylinder liner blank body is manufactured with a through hole; The two ends of cylinder liner blank body are manufactured with the path annulus; The middle part of cylinder liner blank body is manufactured with big footpath annulus, footpath annulus during the both sides of big footpath annulus are manufactured with; The length dimension of described cylinder liner blank body is 356mm, and the diameter dimension of through hole is 65mm, and the path annulus is of a size of 117mm, and big footpath annulus is of a size of 125mm.
The utility model beneficial effect compared with prior art is:
All two cylinder toison base substrates of this centrifugal pressure casting can at least two cylinder liner blank spares of once-cast, and machining allowance is little, saves material, and passing rate of processing is high, low cost of manufacture.Solved existing cylinder liner blank body and all be to having a little the hollow cylinder of tapering, and can only make by single blank, the machining allowance of blank body is big, and passing rate of processing is low, not only wastes raw material, and increases the problem of manufacturing enterprise's manufacturing cost.
Description of drawings:
Accompanying drawing 1 is all two cylinder toison blank structure schematic representation of a kind of centrifugal pressure casting.
Among the figure: 1, cylinder liner blank body, 2, through hole, 3, the path annulus, 4, middle footpath annulus, 5, big footpath annulus.
Embodiment:
All two cylinder toison base substrates of this centrifugal pressure casting are made up of cylinder liner blank body and through hole; The center of cylinder liner blank body is manufactured with a through hole; The two ends of cylinder liner blank body are manufactured with the path annulus; The middle part of cylinder liner blank body is manufactured with big footpath annulus, footpath annulus during the both sides of big footpath annulus are manufactured with; The length dimension of described cylinder liner blank body is 356mm, and the diameter dimension of through hole is 65mm, and the path annulus is of a size of 117mm, and big footpath annulus is of a size of 125mm (referring to accompanying drawing).
All two cylinder toison base substrates of this centrifugal pressure casting form through centrifugal casting machine cast, and it is few that the blank body carries out mach bite, add man-hour two cylinder liner blank bodies and process simultaneously, and the center that machines back annulus from big footpath is cut and is two cylinder sleeve finished products.
The above is the embodiment of this model utility; The above-mentioned flesh and blood that illustrates not model utility constitutes restriction; Under the those of ordinary skill of technical field after having read this specification, can make an amendment or be out of shape above-mentioned embodiment, and do not deviate from the essence and the scope of the utility model.
