Abstract

The utility model relates to a frock is made to cold change of big specification aluminum alloy cylinder, including the saddle support, saddle support upper portion horizontal direction supports installs the plug, the plug mid -mounting has aluminum alloy cylinder, is located the spacing ring of installing the symmetry on the plug at aluminum alloy cylinder both ends respectively, and the top that is located aluminum alloy cylinder is provided with the hydraulic press. The utility model discloses compact structure, reasonable, convenient operation through the underreamed method of saddle support, carries out radial reaming to the big specification aluminum alloy cylinder of this class on hydraulic press equipment, reach the purpose of eliminating residual stress.

Description

A kind of cold change fabricating tools of large-size aluminum alloy cylindrical member
Technical field
This utility model relates to forging and forming technology technical field, especially a kind of cold change fabricating tools of large-size aluminum alloy cylindrical member.
Background technology
After the heat treatment, there is very big residual stress in alloy product, it will causes that product deforms when final processed finished products, cause product rejection.For this problem, in prior art, aluminium alloy cold deformation technology mainly has: by shape expanding machine cold expanding shape and axial cold press technique, it is possible to abatement residual stress.Both approaches has the good effect of comparison for smaller workpiece, and for big barrier part with a high standard (height more than 1m, more than diameter 1.5m) alloy product, the power that bulging needs, disclosure satisfy that this requirement currently without shape expanding machine;Due to highly relatively big, axially colding pressing, deformation is only effective in the very small part of upper and lower end face, it is impossible to reaches cold deformation entirety and eliminates the requirement of residual stress.
Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, a kind of cold change fabricating tools of large-size aluminum alloy cylindrical member is provided, thus realizing the cold deformation to large-size aluminum alloy cylindrical member (height more than 1m, more than diameter 1.5m), reach to eliminate the purpose of product residual stress.
The technical scheme that this utility model adopts is as follows:
A kind of cold change fabricating tools of large-size aluminum alloy cylindrical member, including saddle support, described saddle support upper level direction supports and is provided with plug, aluminium alloy cylindrical member is installed in the middle part of described plug, being positioned on the plug at aluminium alloy cylindrical member two ends and be separately installed with symmetrical spacing ring, the top being positioned at aluminium alloy cylindrical member is provided with hydraulic press.
The end face of the side of described spacing ring and aluminium alloy cylindrical member is close to.
The beneficial effects of the utility model are as follows:
This utility model compact conformation, rationally, easy to operate, by the method for saddle support reaming, such large-size aluminum alloy cylindrical member is carried out by hydraulic press equipment radially reaming, reach to eliminate the purpose of residual stress.
The face of original cold press technique is contacted and changes linear contact lay into by this utility model, reduces the requirement to equipment.
This utility model adopts bulk deformation: by process control, finally make product entirety homogeneous deformation, is conducive to overall elimination residual stress.
This utility model is applicable to large-size aluminum alloy cylindrical member (height more than 1m, more than diameter 1.5m), it is achieved that overall cold deformation.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As depicted in figs. 1 and 2, the cold change fabricating tools of large-size aluminum alloy cylindrical member of the present embodiment, including saddle support 2, saddle support 2 upper level direction supports and is provided with plug 1, aluminium alloy cylindrical member 4 is installed in the middle part of plug 1, being positioned on the plug 1 at aluminium alloy cylindrical member 4 two ends and be separately installed with symmetrical spacing ring 3, the top being positioned at aluminium alloy cylindrical member 4 is provided with hydraulic press.
The end face of the side of spacing ring 3 and aluminium alloy cylindrical member 4 is close to.
The manufacturing process of large-size aluminum alloy cylindrical member cold change fabricating tools is as follows:
The first step: aluminium alloy cylindrical member 4 is mounted on plug 1, installs spacing ring 3 in the both sides of aluminium alloy cylindrical member 4;
Second step: drive plug 1 to rotate by driving device, the frictional force between plug 1 and aluminium alloy cylindrical member 4 can drive it and then to rotate, and in rotation process, carries out radially colding pressing to aluminium alloy cylindrical member 4 by hydraulic press;The velocity of rotation of plug 1 is 5 °-10 °/times, hydraulic press drafts 1mm/ time.
3rd step: by constantly rotating and radial deformation, accurately measures aluminium alloy cylindrical member 4 wall thickness in process, when final products wall thickness is equal with spacing ring 3 wall thickness, and end of colding pressing.
Lubricating method of the present utility model is particularly as follows: on hydraulic press, by saddle support 2 and plug 1, carry out radially colding pressing deformation to large-size aluminum alloy cylindrical member 4, controls forging wall thickness by spacing ring, is finally reached elimination residual stress and ensures product size.
Above description is to explanation of the present utility model, is not the restriction to utility model, and this utility model limited range is referring to claim, within protection domain of the present utility model, it is possible to do any type of amendment.
