Inner sleeve thickness, which can't generate, largely to be reduced, and the difficulty of production is also added.
Utility model content
The purpose of this utility model is to provide a kind of double-deck heat dissipation type cylinder sleeves, are double-deck and single layer structure by cylinder sleeve
At a cylinder sleeve so that air can directly circulate in cylinder sleeve, so that cylinder sleeve is in the collection middle section of piston press air
Single layer section guarantee cylinder sleeve possesses enough mechanical strengths, prevents detonation.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions:
The utility model is a kind of double-deck heat dissipation type cylinder sleeve, including liner body, and the liner body is by cylinder and flange
The single piece constituted, the cylinder include bitubular section and monotubular section, are equipped with several support arc panels, two institutes in the bitubular section
It states and forms an arc groove between support arc panel, the monotubular section is equipped with several through-holes, on several through-holes and bitubular section
Arc groove penetrates through between two barrels, and several through-holes are penetrated through by arc groove between two barrels in " V " type hole and bitubular section,
The through-hole runs through flange.
Further, described " V " type hole is opened in the contact position of support arc panel and monotubular section.
Further, the interior barrel thickness of the bitubular section is greater than outer barrel thickness.
Further, the length of the bitubular section is between the 1/2~2/3 of liner body length.
The utility model has the following beneficial effects:
The utility model structure is simple, and cylinder sleeve is the cylinder sleeve that double-deck and single layer is constituted, so that air can
It directly circulates in cylinder sleeve, so that cylinder sleeve possesses enough machines in the middle section that integrates of piston press air as single layer section guarantee cylinder sleeve
Tool intensity, prevents detonation, reduces the thickness of the bitubular layer inner cylinder while increasing device radiation, reduces the quality of cylinder sleeve, reduces
At the use for producing raw material.
Certainly, any product for implementing the utility model does not necessarily require achieving all the advantages described above at the same time.
