Abstract
The present invention provides a kind of tubular member moulding process, it is characterised in that comprises the following steps that：（1）Pipe Cutting process：Required to carry out pipe fitting cutting according to the size of part；（2）Preforming operation：By the pipe fitting of well cutting by one or more processes such as bending, die mould, extruding, pre-production is into certain shape；（3）High pressure bulging process：Mould inside will be placed on by the pipe fitting of preforming operation, and seals pipe fitting both ends, highly pressurised liquid is injected into inside pipe fitting, pipe fitting is bonded with mould inner wall；（4）Cut off molding procedure：The excessive parts of high pressure bulging process rear tubular member are removed, obtain part.The present invention provides solution for the shaping of pipe part, significantly lifts stock utilization and the mechanical performance of product, and mechanical property is more perfect, promotes light-weight design, reduces the cost of raw material；Improve the strength and stiffness of part；Simplify production procedure, improve product quality；Improve the gas flow characteristic in pipe fitting, planform designs the lightweight that more becomes, flexible, optimization；R ＆ D design while having saved development cost also for other parts provides more spatial selectivities.
Description
Technical field
The invention mainly relates to pipe part, more particularly to a kind of tubular member moulding process.
Background technology
Tubular material hydroforming can save material compared with punch welding part, mitigate weight, and general structure part can subtract
Weight 20%-30%, axial workpiece can loss of weight 30%-50%, such as secondary car frame, general stamping parts weight is 12kg, internal high pressure forming zero
Part is 7-9kg, loss of weight 34%, radiator bearer, general stamping parts weight 16.5kg, and internal high pressure forming part is 11.5kg, loss of weight 24%,
And follow-up machining and group weldering workload can be reduced, the intensity and rigidity of component are improved, fatigue is improved because solder joint is reduced
Intensity.
Pipe part stock utilization is 95-98%, reduces production cost and die cost 30%, so increasing pipe
Class part applies to every field, but the shaping of pipe part is compared and is difficult to resolve certainly, and inner high voltage bulging technology solves well
This problem.
The content of the invention
The present invention provides a kind of tubular member moulding process, it is characterised in that：It is characterised in that it includes following technique step
Suddenly：
（1）Pipe Cutting process：Required to carry out pipe fitting cutting according to the size of part；
（2）Preforming operation：By the pipe fitting of well cutting by one or more processes such as bending, die mould, extruding, pre-production into
Certain shape；
（3）High pressure bulging process：Mould inside will be placed on by the pipe fitting of preforming operation, and seals pipe fitting both ends, by height
Press liquid injects inside pipe fitting, pipe fitting is bonded with mould inner wall；
（4）Cut off molding procedure：The excessive parts of high pressure bulging process rear tubular member are removed, obtain part.
Preferably, cut-out molding procedure carries out the cut-out of pipe fitting using laser or the mode of punching press.
Preferably, in addition to technological design process, the technological design process are arranged on before Pipe Cutting process.
Beneficial effects of the present invention：Low-temperature steel flange forge piece provided by the invention, solution is provided for the shaping of pipe part
Scheme, stock utilization and the mechanical performance of product are significantly lifted, mechanical property is more perfect, promotes light-weight design, drop
The low cost of raw material；Improve the strength and stiffness of part；Simplify production procedure, improve product quality；Improve the gas in pipe fitting
Flow behavior, planform design the lightweight that more becomes, flexible, optimization；Also it is other parts while having saved development cost
R ＆ D design provides more spatial selectivities.
