Abstract
The invention relates to a seal of a front sealing head of a high-pressure gas cylinder and a machining method of the seal. The seal comprises the front sealing head. Step holes are formed in the upper end of the front sealing head and comprise three steps of a sealing needle hole, a lock needle hole and a diffusion hole. The aperture of the sealing needle hole, the aperture of the lock needle hole and the aperture of the diffusion hole are gradually increased in sequence. The step holes are adopted, the two ends are drilled, the machining method of carrying out drilling, chambering and reaming in sequence is adopted, and therefore the surface smoothness of the holes can be guaranteed, the coaxiality of the holes can be guaranteed, and a matching needle can be easily sealed.
Description
Technical field
The present invention relates to a kind of gas cylinder processing method, particularly relate to the sealing of a kind of gas cylinder front head and processing method thereof.
Background technology
Gas cylinder is missile propulsive plant gas and oil circuit system key fitment, is the critical component ensureing to stablize in gas and oil loop air pressure, and wherein gas cylinder sealing is after inflation, enables gas be long-term stored in gas cylinder, ensures the major part of gas cylinder seal.All doing one's utmost to seek structure simply, hermetically-sealed construction easy to process and method to the sealing problem of gas cylinder always.Produce withstand voltage height, period of storage is long, stability is high gas cylinder is the target developing in the industry and pursue.
But prior art mesohigh gas cylinder front head enclosuring structure is complicated, and processing method is loaded down with trivial details, often occurs gas leakage, and sealing can not be guaranteed, and cannot ensure loop air pressure.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide the sealing of a kind of gas cylinder front head, solve the problem that prior art mesohigh gas cylinder front head sealing leak is not high.
Another object of the present invention is to the processing method providing a kind of gas cylinder front head to seal.
technical scheme of the present invention is as follows:
Gas cylinder front head seals, and comprise front head, the upper end of front head arranges shoulder hole, and described shoulder hole comprises envelope pin hole, purl hole and diffusion hole three rank, and the aperture of described envelope pin hole, purl hole and diffusion hole increases progressively successively.
Processing method of the present invention comprises the steps:
The aperture size of envelope pin hole, purl hole and diffusion hole is set to φ a, φ b and φ c respectively;
Step 1, bows with direction, front head lower end and sees, bore diffusion hole, aperture is φ c, and hole depth is 18-25mm;
Step 2, bows with direction, front head upper end and sees, boring A, and aperture is φ b-0.2, and hole depth is 8-12mm;
Step 3, carries out reaming by step 2 gained hole A, and expand aperture φ b-0.2 to φ b, reaming is 1-3mm deeply, obtains purl hole;
Step 4, carries out reaming by step 2 gained hole A, and expand aperture φ b-0.2 to φ b-0.1, reaming is 6-10mm deeply, obtains hole B;
Step 5, ream hole B to aperture φ a, the degree of depth is 6-10mm, obtains envelope pin hole, then carries out gating to envelope pin hole;
Step 6, enters to seal pin hole by envelope stylus printer, relies on the orifice ring footpath of envelope pin hole to seal gas cylinder.
advantageous effect of the present invention is as follows:
The present invention adopts shoulder hole, and carries out Drilling operation respectively to two ends, and employing is first holed, then reaming, finally carries out the processing method reamed, can not only ensure the surface smoothness in hole, and can ensure the axiality in hole, gating is sealed and easily realizes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1, front head, 2, envelope pin hole, 3, purl hole, 4, diffusion hole.
