Description
Technical field
The present invention relates to metallic packing ring processing technique fields, specifically, be a kind of metallic packing ring process equipment and
Numerically-controlled machine tool.
Background technique
Existing radial direction metallic packing ring generallys use the positive circule method of forging and casting, coiling forming positive round method or forging and casting profile lathing
Mode completes the process.
It is that the blank of forging or casting is passed through to turning inside and outside circle, is cut that the positive circule method of forging and casting, which processes radial metallic packing ring,
Piece, opening, thermal finalization, carries out the processes completions such as mill inside and outside circle, mill Double End, grinding, honing at heat treatment again.Forging and casting positive round
The method processing radial metallic packing ring production cycle is long, at high cost.The defects of being also easy to produce shrinkage cavity, crackle due to forging and casting material produces
Product qualification rate is usually 60% or so.Radial metallic packing ring being also easy to produce embrittlement, fractureing in processing, assembly and use process
Problem.
It is to shape the strip of customization by way of around positive round that coiling, which shapes positive round method to process radial metallic packing ring, is saved
The links such as turning inside and outside circle, slice, heat treatment have been gone, after thermal finalization, repairing mouth, then mill inside and outside circle has been carried out, mill Double End, grinds
The processes such as mill, honing are completed.Coiling shapes positive round method and processes the production cycle of radial metallic packing ring compared to the positive circule method of forging and casting
Substantially shorten.Strip is processed by way of drawing, and fault in material is few, and the qualification rate of product can be promoted to 80% or so.
The method of forging and casting profiling Vehicle Processing radial direction metallic packing ring is that the blank of forging or casting is passed through contour turning
Inside and outside circle, heat treatment, opening, thermal finalization, carries out the processes completions such as mill inside and outside circle, mill Double End, grinding, honing at slice again.Forging
The issuable fault in material of casting so that product qualification rate is less than 60%, the sealing ring of production in processing, assemble and used
In journey be also easy to produce embrittlement, fracture problem.
The metallic packing ring that the positive circule method processing of forging and casting and coiling forming positive round method complete the process cannot form free state
Under equal pressure curves, therefore deposit in the operating condition, the border pressure of sealing pair is uneven, the undesirable disadvantage of sealing effect.
It will appear sealing ring border in use process and wear inconsistent problem, cause sealing ring service life short.
The radial metallic packing ring that forging and casting profile lathing completes the process although be capable of forming under sealing ring free state etc.
Pressure curve, guarantees the border equalization of pressure of sealing ring sealing pair in the operating condition, but it is long to still remain the production cycle, cost
High disadvantage, and there is also the problem of reserving biggish chipping allowance is needed in process, the processing of usually interior outlet
Surplus in 3~5mm or more, and due to everywhere in interior outlet machining allowance differ, residualinternal stress everywhere in part after processing
It differs greatly, haves the shortcomings that production efficiency is low, part qualification rate is not high.
Summary of the invention
It is an object of the invention to design a kind of metallic packing ring process equipment and numerically-controlled machine tool, it is able to solve positive circule method
The radial metallic packing ring of processing cannot form the technical issues of equal pressure curves under free state, while solve profile lathing
The technical issues of residualinternal stress differs greatly everywhere in part after processing existing for radial metallic packing ring is processed, positive round is evaded
Disadvantage present in method and profiling Vehicle Processing metallic packing ring combines positive circule method and profiling Vehicle Processing metallic radial sealing ring

Step S13: sealing ring is packed and stored.
By taking φ 136 shown in FIG. 1 seals the pressure curves such as folded ring as an example, the unit of each numerical value in Fig. 1 is mm, horizontal axis axis
To being X to the longitudinal axis is axially Y-direction, and respectively equal certain point of the pressure curves at outer circle having a size of sealing ring is relative to sealing ring
X at center to apart from coordinate and Y-direction apart from coordinate.Had using the metallic packing ring numerical control machine for processing processing of embodiment 3
When φ 136 seals the sealing rings of pressure curves such as folded ring, control system is according to driven wheel on the inside of the revolving speed real-time control of driving wheel 2
3 and outside driven wheel 4 floating movement, for example lighted from the right side of opening first, control system control inside 3 He of driven wheel
Outside driven wheel 4 floats to corresponding position, and driving wheel 2 continues feeding, inside driven wheel 3 and outside driven with the steering in Fig. 2
Wheel 4 floats to corresponding position and obtains second point and thirdly, and so on, up to obtaining last on the left of sealing ring opening
It is a, then obtain equal pressure curves sealing ring.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.
