Abstract
The present invention is a kind of fire-fighting spraying head production method peculiar to vessel, and step includes: step 1 punches spray head part with drill bit；Step 2 carries out cutting hole processing using the inner hole that fluted drill makes step 1 since the tail portion of spray head part.The drill bit of 8mm is used in the step 1.The slope of the head of fluted drill used in the step 2 to tail portion is equal to 0.0437, and, the diameter of fluted drill tail portion is greater than 22mm, and the diameter on fluted drill head is less than 8mm.The producing efficiency of fire-fighting spraying head peculiar to vessel can be greatly improved through the invention, and guarantees finish in fire-fighting spraying head bore peculiar to vessel.Reach the production requirement of spray head by the improvement to technique while being greatly reduced production cost.
Description
Technical field
The present invention relates to the manufacture craft improvement of fire-fighting spraying head on certain naval vessel.
Background technique
As shown in attached drawing 1, attached drawing 2, fire-fighting spraying head is the water injector used on certain naval vessel, and head is spherical, tail
Portion is bar shaped.Defined fire-fighting spraying head internal holes are cone-shaped inside standard, and head is equipped with the hole of 8mm, and tail portion is equipped with
The hole of 22mm, and the hole on head to tail portion hole slope be 0.0437.The device is mainly used for deck plane and equipment surface
Daily cleaning, its main feature is that it is light and handy it is convenient be easy to one-handed performance, therefore the spray area of bed is smaller and internal has waterflow boosting to set
Meter, since its smaller interior cone compression portion difficulty of processing of component overall dimensions is very big and interior cone surface has finish to want
It asks, so being unable to satisfy the design requirement of component with traditional manufacturing process.
Shown in attached drawing 3, the inside of spray head is gradually transitioned into top diameter 8mm length from base diameter 22mm to be cone-shaped
It for 160mm, can not be processed since interior cone length is too long with traditional machine cut Boring cutter, knife when tool sharpening is to middle part
Can encounter inner wall can not feed again, after to Boring cutter carry out it is a series of repacking be all unable to complete processing.As shown in Fig. 4, right
Tool arm lengthening attenuates finds cutting Boring cutter when processing spray head inner wall due to part rotation and cutting resistance after repacking is handled
Lower tool arm, which is deformed, is unable to complete processing operation, so the repacking to tool arm ends in failure.It is mentioned again by repeatedly discussion afterwards
Gone out several production programs, such as be directly changed to steel-casting, but due to casting expense it is excessive and also cast after inner hole finish without
Method guarantees so also without implementing to adopt.
Summary of the invention
The present invention solves the problems, such as that above-mentioned prior art exists, and design provides a kind of safety valve toucher tooling.
A kind of fire-fighting spraying head production method peculiar to vessel, step includes:
Step 1 punches spray head part with drill bit；
Step 2 carries out cutting hole processing using the inner hole that fluted drill makes step 1 since the tail portion of spray head part.
Preferably, in the step 1, drill bit passes through the central axis of the spray head part, and the size in hole is less than or equal to
8mm。
Preferably, the drill bit of 8mm is used in the step 1.
Preferably, the slope of the head of fluted drill used in the step 2 to tail portion is equal to as defined in spray head standard
Slope.
Preferably, the head of fluted drill used in the step 2 to tail portion slope be equal to 0.0437, and,
The diameter of fluted drill tail portion is greater than 22mm, and the diameter on fluted drill head is less than 8mm.
Preferably, in the step 2, after the fried dough twist drawbore, the head of spray head part is equipped with 8mm's
Hole, the tail portion of spray head part are equipped with the hole of 22mm, and the slope in hole of the hole on spray head part head to tail portion is
0.0437。
Preferably, the fluted drill is equipped with flute, to go out to consider to be worth doing when cutting hole.
The producing efficiency of fire-fighting spraying head peculiar to vessel can be greatly improved through the invention, and guarantees fire-fighting spraying head peculiar to vessel
Finish in hole.

Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Closing the drawings and specific embodiments, the present invention will be further described in detail, the range of but do not limit the invention in any way.
As shown in Fig. 4, the step of the method for the present invention includes:
Step 1 punches spray head part with drill bit；Drill bit passes through the central axis of the spray head part, through spray
The head to tail portion of head part.
Step 2 carries out cutting hole processing using the inner hole that fluted drill makes step 1 since the tail portion of spray head part.
Wherein, the drill bit of 8mm is used in the step 1.The head of fluted drill used in the step 2 is to the oblique of tail portion
Rate is equal to 0.0437, and, the diameter of fluted drill tail portion is greater than 22mm, and the diameter on fluted drill head is less than 8mm.
In the present invention, the restructuring polishing of fluted drill requires very high, it is necessary in the slope and spray head of fluted drill
The slope of portion's pressurization cone is consistent, and in addition to guarantee the cutting hardness and flute of its drill bit blade after fluted drill polishing
Consider function to be worth doing out.Reach the production requirement of spray head by the improvement to technique while being greatly reduced production cost.
It is discussed in detail although the contents of the present invention have passed through above-mentioned preferred embodiment, but it should be appreciated that above-mentioned retouches
It states and is not considered as limitation of the invention.After those skilled in the art have read above content, for of the invention a variety of
Modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be by the attached claims.
