Abstract
Spin forming process is rushed the invention discloses a kind of stainless steel end socket, the step of this rushes spin forming process is as follows: a, selecting steel plate according to the material and size of wanted molding stainless steel end socket and cut；B, welding is carried out to the steel plate being cut into and butt welding seam weld seam carries out polishing processing；C, the steel plate after being polished using stamping die to welding is carried out punching press and constitutes a hat-shaped, and R part punching press is in place；D, rotary press modelling is carried out to the position r using spinning machine；E, the groove of the end socket obtained after punch forming and rotary press modelling is repaired；F, weld seam is carried out non-destructive testing；G, acid wash passivation processing or or heat treatment are carried out to the stainless steel surface of end socket；H, the perimeter, section, total height for measuring end socket, are modified, required end socket is then made in zero deflection if any deviation.The of the invention spin forming process that rushes can save material, reduce cost and improve production efficiency, and have good facilitation for the control of R part shape profile.
Description
Technical field
The present invention relates to seal head molding technical field, specifically one kind can save material, reduce cost and energy
That enough improves the stainless steel end socket of production efficiency rushes spin forming process.
Background technique
All cold formings processing can all generate certain residual stress and cold work reinforced, and end socket is no exception.Such as meet container
Mount stress, welding residual stress, thermal stress when, Stress superposition will be generated, if using in the environment for having stress corrosion,
It is possible to that stress corrosion cracking (SCC) can be generated in a short time.
Summary of the invention
In light of the defects in the prior art, the purpose of the invention is to provide one kind to save material, reduces cost
And the stainless steel end socket that can be improved production efficiency rushes spin forming process.
The purpose of the present invention is what is solved by the following technical programs:
A kind of stainless steel end socket rushes spin forming process, it is characterised in that: it is as follows that this rushes the step of spin forming process:
A, selection is cut: being selected steel plate according to the material and size of wanted molding stainless steel end socket and is cut；
B, welding polishes: carrying out welding to the steel plate being cut into and butt welding seam weld seam carries out polishing processing；
C, punch forming: the steel plate after being polished using stamping die to welding is carried out punching press and constitutes a hat-shaped, R part punching
It is pressed onto position and R part template makes section configuration control within 5mm；
D, rotary press modelling rotary press modelling: is carried out to the position r using spinning machine；
E, it repairs groove: the groove of the end socket obtained after punch forming and rotary press modelling is repaired；
F, seam inspection: weld seam is carried out non-destructive testing；
G, acid wash passivation processing or or heat treatment pickling or heat treatment: are carried out to the stainless steel surface of end socket；
H, measurement amendment: the perimeter, section, total height of end socket are measured, is modified if any deviation, required envelope is then made in zero deflection
Head.
Welding in the step (b), which polishes, requires weld seam that must not be below or above base material 0.5mm or more.
Non-destructive testing in the step (f) refers to that carrying out 100%RT detection to weld seam complies with JB/T4730.2-
2005 standards；Repair, the non-destructive testing qualification if zero defect are needed as defective.
The perimeter of end socket in the step (h) can control within ± 2mm.
Steel plate in the step (a) uses austenite stainless steel plate.
The present invention has the following advantages compared with prior art:
Of the invention rushes for spin forming process comparison punch forming, and blank size is smaller, can save material, punch forming
End socket in punching course due to the longevity of service of machine, generate that also result in size after heat inaccurate, and need to revolve
Pressure adjustment size, and rushing the molding end socket of rotation can be by perimeter control within ± 2mm, the end socket high for tolerance is not
It only saves material, can also save process time.
Of the invention rushing for spin forming process compares drum pressure spinning is exactly greatly to have saved process time, and drum pressure is one
A process time longest manufacturing procedure, smooth R part could be extruded by needing constantly to adjust compacting, and punching press is instead of pressure
Bulging lengthy procedure has not only been saved a large amount of process time, the processing efficiency of raising, and for R part shape profile
Control has good facilitation.
Specific embodiment
Below with reference to embodiment, the present invention is further illustrated.
The step of a kind of stainless steel end socket rushes spin forming process, this rushes spin forming process is as follows:
A, selection is cut: being selected austenite stainless steel plate according to the material and size of wanted molding stainless steel end socket and is cut
It cuts；
B, welding polishes: carrying out welding to the steel plate being cut into and butt welding seam weld seam carries out polishing processing, it is desirable that weld seam must not
Below or above base material 0.5mm or more；
C, punch forming: the steel plate after being polished using stamping die to welding is carried out punching press and constitutes a hat-shaped, R part punching
It is pressed onto position and R part template makes section configuration control within 5mm；
D, rotary press modelling rotary press modelling: is carried out to the position r using spinning machine；
E, it repairs groove: the groove of the end socket obtained after punch forming and rotary press modelling is repaired；
F, seam inspection: carrying out non-destructive testing weld seam, and non-destructive testing refers to that carrying out 100%RT detection to weld seam complies with JB/
T4730.2-2005 standard；Repair, the non-destructive testing qualification if zero defect are needed as defective；
G, acid wash passivation processing or or heat treatment pickling or heat treatment: are carried out to the stainless steel surface of end socket；
H, measurement amendment: the perimeter, section, total height of end socket are measured, is modified if any deviation, required envelope is then made in zero deflection
Head.
Of the invention rushes for spin forming process comparison punch forming, and blank size is smaller, can save material, punching press
Molding end socket due to the longevity of service of machine, generates that also result in size after heat inaccurate in punching course, and needs
Spinning adjustment size is wanted, and rushing the molding end socket of rotation can be by perimeter control within ± 2mm, the envelope high for tolerance
Head not only saves material, and can also save process time.This is exactly greatly to save for rushing spin forming process comparison drum pressure spinning
About process time, drum pressure is a process time longest manufacturing procedure, need constantly to adjust compacting could extrude it is smooth
R part, and punching press has not only been saved a large amount of process time instead of the lengthy procedure of drum pressure, the processing efficiency of raising, and
And there is good facilitation for the control of R part shape profile.
The above examples only illustrate the technical idea of the present invention, and this does not limit the scope of protection of the present invention, all
According to the technical idea provided by the invention, any changes made on the basis of the technical scheme each falls within the scope of the present invention
Within；The technology that the present invention is not directed to can be realized by the prior art.
