The technical problem that the present invention mainly solves is to provide a kind of blasting craft of aviation fire-suppression bottle end socket, can effectively control the evenness of wall thickness in seal head forming process, on the basis that guarantees properties of product, alleviates product weight.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the blasting craft that a kind of aviation fire-suppression bottle end socket is provided, comprise the following steps: a. pretreatment: check sand-blasting machine, air compressor and blast nozzle, and pass into compressed air to air compressor; B. sandblast: the end socket of fire-suppression bottle is carried out to sandblast, in blast nozzle both sides, baffle plate is set, in sandblast process, blast nozzle slowly moves, and fire-suppression bottle at the uniform velocity rotates; C. cleaning: the sand grains and the sand-lime that clean out fire-suppression bottle end socket surface; D. check: the roughness on check fire-suppression bottle end socket surface.
In a preferred embodiment of the present invention, in described step a, in air compressor, pass into the compressed air of 0.5-0.6MPa.
In a preferred embodiment of the present invention, in described step b, fire-suppression bottle rotary speed is 1-3 rev/min.
In a preferred embodiment of the present invention, in described step c, by the dry compressed air of air compressor, blow away sand grains and the sand-lime on bottle surface.
In a preferred embodiment of the present invention, in described steps d, the roughness on fire-suppression bottle end socket surface is Sa2.5.
The invention has the beneficial effects as follows: the blasting craft of aviation fire-suppression bottle end socket of the present invention, can effectively control the evenness of wall thickness in seal head forming process, on the basis that guarantees properties of product, alleviate product weight.
