Background technique
Space product cover class class part category general assembly is with plate in space product by manual mould pressing directly under structural member
And the thin-walled parts completed, there is barrel-shaped depth deep, material thickness is thin, the big feature of manual spinning difficulty, can be divided by shape
Cone-shaped hood class, straight cylindrical cover class.
Due to the difference of product structure, design of part and size are also not quite similar, and still, all kinds of cover class element precisions are all right
Section final product structure size has vital effect, and part flange dimensional accuracy, intensity all would potentially result in portion
The overproof and possible potential hidden danger of quality of section Product Assembly.Design requirement part flange and tubular corner R radius of corner
Having a size of 2~3mm, due to being manual spinning during shaping its flange, part corner root can not completely and spinning
Core model fitting, therefore there are a transition regions having a size of 10~15mm, after spinning to detail drawing design height, it is necessary to
Part flange corner transition region is carried out using tooling to squeeze school shape, to meet the size requirement of the root drawing R.For a long time with
Come, part is not removed after manual mould pressing, but part is pressed into together with spinning mandrel in the shape tooling of school, passes through school shape
Tooling and spinning mandrel correct shape corner transition region biggish on part, and the school shape tooling generallyd use is such as 1 institute of attached drawing
Show the device like that there is no limit cavity heights, during the shape of school the corner of flange can due to extruding Free Transform, thus bright
It shows thinning, therefore causes that part thickness is overproof and height dimension is unstable.And craft spinning operation technical difficulty is big, and previous one
The straight processing method guaranteed the quality using quantity, needs more adjustment material, and the forming qualification rate of part is only 60%, and waste is big,
Production cycle is long, higher to operator's technical requirements, and the above problem restricts general assembly progress for a long time and cannot effectively solve.
Summary of the invention
Based on problem above, the purpose of the present invention is to provide a kind of cylinder part and its flange straightening methods.
In order to achieve the goal above, the technical solution adopted by the present invention are as follows: a kind of cylinder part and its flange straightening method, packet
Include following steps:
Blank spinning is formed the cylindrical body that opening has flange, the cylinder of cylindrical body using spinning apparatus by step 1
Height is higher than design requirement height, guarantees that biggish radius of corner, flange and cylinder corner are not present in design requirement height
The radius of corner at place is greater than design requirement size；
Cylindrical body is put into the cavity of cavity plate and is bonded with the inner wall of cavity and bottom by step 2, the shape of cavity with to
Shape adaptation outside the shape cylinder part of school, the height of cavity is identical as the height to be processed to school shape cylinder part, then by the convex of punch-pin
Portion is from the indentation of the opening of cylindrical body, the shape of protrusion and to the shape adaptation inside the shape cylinder part of school, wherein on the protrusion of punch-pin
The upper splenium that end setting projects radially outward, the cavity upper end of cavity plate are arranged the pressing down section projected radially outward, punch-pin are pressed into
During cylindrical body, upper splenium and pressing down section are by the flange of cylindrical body and flange and the correction of cylinder corner to making flange
Side is consistent with design requirement size with the radius of corner of cylinder corner, to obtain the cylinder part with flange.
Optimization, through-hole is arranged in order to the taking-up of cylinder part after the shape of school in the bottom of the cavity.
Optimization, it is to be processed higher than to school shape cylinder part that spinning portion axial height is set on spinning apparatus in the step 1
Then blank is installed on the spinning portion of spinning mandrel, then starts spinning apparatus, passes through manual spinning by the spinning mandrel of height
Method obtains the cylindrical body that cylinder height is higher than design requirement height.
Optimization, punch-pin is pressed by cylindrical body using press machine in the step 2, punch-pin is by being set to upper splenium upper end
Die shank connect with press machine.
Optimization, the position of practical school shape is that cylindrical body is higher than the cylinder section of design size and is attached thereto in the step 2
The flange with the radius of corner beyond design size, this method becomes the Forming Theory on conventional flange side by local elongation
Shape changes into local contraction deformation, and the flange of obtained cylinder part and the corner thickness of cylinder are uniform, proposes the quality of product, turns
Radius of corner is having a size of 2~3mm at angle.
The invention has the benefit that
(1), cylinder part and its flange straightening method provided by the invention, first pre- delivery lift is higher than to school shape cylinder part height
First cylinder, then by cavity plate and punch-pin by first cylinder correction at height, the satisfactory cylinder part of flange, process velocity
Fastly, product qualification rate is up to 100%, and is not in that part is overproof and scraps, to improve production efficiency, and its mold uses
Common material is made, and material utilization amount is few, and clever structure is simple.
