Abstract
The present invention is a kind of metal cylinder liner processing method, including：Sheet metal is cut into required shape and size with cutting machine, the sheet metal of well cutting is drawn into cylindrical member on forcing press through primary or Multi-step forming again, then cylindrical member is revolved by force bowl wall portion on Qiang Xuanji thinned, finally the cylindrical member of strong supination through spinning closing-in, heat treatment, bottleneck is processed, just forms single bottle mouth cylinder liner；Or after cylindrical member is revolved by force bowl wall portion on Qiang Xuanji is thinned, the bottom of cylindrical member is cut away to form tubular member with cutting machine, finally tubular member both ends through spinning closing-in, heat treatment, bottleneck are processed, just form double bottleneck liners.The present invention can produce the cylinder liner of plurality of specifications, while production cost is greatly reduced.
Description
Technical field
Production method more particularly to a kind of production method of metal cylinder liner the present invention relates to a kind of cylinder liner.
Background technology
Metal inner tube composite cylinder is widely applied in terms of fire-fighting, especially chemical industry, vehicle fuel.Metal at present
There are mainly two types of processing methods for cylinder liner：One kind is to be formed by seamless metal pipe through both ends spinning closing-in, and another kind is by gold
Belong to plate and pass through punching stretch, then spinning closing-in forms.
The producible product specification of first way is more, but seamless metal pipe cost is higher, and this processing method only may be used
For the liner of double bottlenecks, it is restricted in the case where client is strict with composite cylinder length；Second way compression function
Power is limited, and range of product size is relatively narrow, and only can work sheet bottleneck liner.
Invention content
The present invention provides a kind of metal cylinder liner processing method, by this to overcome the problems, such as that prior art exists
Method produces metal cylinder liner, can not only produce metal cylinder liner of different size and specifications, is also greatly reduced double
The cost that mouth seamless metal cylinder liner makes.
In order to achieve the above objectives, the present invention includes the following steps：
Cutting step：Sheet metal is cut into required shape and size with cutting machine；
Punching stretch step：The sheet metal of well cutting is drawn into tubular on forcing press through primary or Multi-step forming
Part；
Strong rotation step：Cylindrical member on Qiang Xuanji is revolved by force bowl wall portion thinned；
Closing in step：The cylindrical member oral area of strong supination is formed into single port metal after spinning closing-in, heat treatment, bottleneck processing
Cylinder liner；Or cut away to form tubular member with cutting machine by the bottom of strong supination cylindrical member, finally by tubular member both ends through rotation
Pressure closes up, is heat-treated, forms twoport metal cylinder liner after bottleneck processing.
Further, in order to enhance the crushing resistance of gas cylinder, during single bottle mouth cylinder liner is made, described by tubular
Part revolves bowl wall portion in thinning process by force on Qiang Xuanji, and the thickness of cylindrical member bottom keeps the cylinder body bottom after punching stretch
Wall thickness it is constant.
Further, in order to which bottleneck is firmer, before closing in step, i.e., rotation step is last by force, single bottle mouth cylinder liner
It makes to need to screw out by force in cylindrical member oral area and thickens section；Double bottleneck cylinder liners, which make, to be needed in cylindrical member oral area and close to bottom
Position screw out two sections by force and thicken section, this two sections thicken section for convenient for pair bottleneck cylinder liner both ends shell nosing treatment, thicken
The length of section needs to determine according to the size of cylinder liner bottleneck to be produced and the crushing resistance of gas cylinder with thickening the thickness root of section.
Further, in order to clearly produce the size of cylinder liner specification, the cylinder liner internal diameter is by the strong of Qiang Xuanji
Rotation core bar diameter determines that the periphery wall thickness of the cylinder liner is determined by revolving program by force.
Further, in order to mitigate the weight of cylinder liner, the sheet metal is preferably aluminum alloy plate materials.
Description of the drawings
Fig. 1 is the flow chart of the first embodiment of the invention
Specific embodiment
It will be with reference to illustrative reality to be easier to understand advantages of the present invention, feature and reaching the technical method of technique effect
It applies example to be explained in more detail, and the present invention can realize in different forms, therefore is understood not to that present invention is limited only to this
The embodiment of place statement, on the contrary, to those skilled in the art, the embodiment that is provided will more thoroughly with it is comprehensive and complete
Site preparation conveys scope of the invention, and the present invention will determine protection domain to apply for a patent the claim of file.
Constantly expand as aluminum liner carbon fiber winds composite cylinder application field entirely, the requirement to product specification is also more next
More, the form of product is also more and more.
As shown in Figure 1, the first embodiment of the present invention winds compound single bottle implication entirely to make aluminum liner carbon fiber
The process of bottle liner, including：
Cutting step：The plectane of diameter required for aluminum alloy plate materials are cut by plasma cutting machine；
Punching stretch step：On hydraulic press cylindrical member is formed after Multi-step forming drawing and forming；
Strong rotation step：Cylindrical member on Qiang Xuanji is revolved by force shell portion thinned, internal diameter is ensured by revolving core bar by force, cylinder
Wall thickness ensures that bottom wall thickness keeps the wall thickness after stretching, it can be achieved that bottom wall thickness is more than cylinder in product design by revolving program by force
The requirement of wall thickness；It is screwed out by force in cylindrical member oral area and thickens section, ensure the completion of follow-up spinning closing-in；
Closing in step：By the cylindrical member of strong supination through spinning closing-in, aluminium alloy is formed after then thermally treated, bottleneck processing
Single bottle mouth cylinder liner.
Second of embodiment of the present invention is to make the mistake that aluminum liner carbon fiber winds Composite Double bottleneck cylinder liner entirely
Journey：
Cutting step：The plectane of diameter required for aluminum alloy plate materials are cut by plasma cutting machine；
Punching stretch step：On hydraulic press cylindrical member is formed after Multi-step forming drawing and forming；
Strong rotation step：Cylindrical member on Qiang Xuanji is revolved by force shell portion thinned, internal diameter is ensured by revolving core bar by force, cylinder
Wall thickness is ensured by revolving program by force；Two sections are screwed out in cylindrical member oral area and tail portion by force and thickens section, ensure the completion of follow-up spinning closing-in；
Cut cylinder bottom step：Cylindrical member bottom is cut away with cutting machine, forms tubular member；
Closing in step：Tubular member progress spinning closing-in, heat treatment, bottleneck are processed to be formed in the double bottleneck gas cylinders of aluminium alloy
Courage.
