Abstract
The present invention is a kind of circular foil member casted die mould with straight flange, belongs to material forming field.Including upper mold (1), lower die (2), pedestal (5), positioning sleeve (6)；Positioning sleeve (6) is connected through a screw thread with pedestal (5), the outer circle of upper mold (1) is slidably matched with the holding of positioning sleeve (6) inner circle, upper mold (1) keeps concentric with lower die (2), and the lower end surface SR size of upper mold (1) and the upper surface SR difference of lower die (2) are equal to a sheet thicknesses.Main body of the present invention is divided into upper and lower mould and edge pressing structure, is determined by experiment upper/lower die and edge pressing structure size, guarantees the compact dimensions of the circular foil member with straight flange by upper/lower die, to meet the molding demand of circular foil member.It is wrinkled when preventing shaping sheet metal by edge pressing structure, promotes surface quality of workpieces.
Description
Technical field
The present invention is a kind of circular foil member casted die mould with straight flange, belongs to material forming field.
Background technique
Existing circular foil member (hereinafter referred sheet metal) forming technique with straight flange: through the upper mold of mold under
Mould carries out punch forming to the circular foil member with straight flange, and the circular foil member edge with straight flange generates in forming process
Very big tangential pressure leads to construction instability, generates fold.Generate fold after upper mold carry out again push cannot be completely by pleated portions
Partial pressure is flat.So having to first edge be compressed before the circular foil member molding with straight flange, apply pressure-pad-force, then
Die mould.Due to the press machine that the circular foil member molding equipment with straight flange is tonnage very little, no liftout tank, and the size of mold
It is limited, so pressure-pad-force can not be provided to mold according to traditional thinking press machine.
Summary of the invention
Goal of the invention: in limited die space, meet formed product size and require while solving sheet metal straight flange pressure
Occurs the problem of fold when type.
Technical solution: a kind of circular foil member casted die mould with straight flange it is characterized in that, mold include upper mold 1, under
Mould 2, pedestal 5, positioning sleeve 6；Positioning sleeve 6 is connected through a screw thread with pedestal 5, and the outer circle and 6 inner circle of positioning sleeve of upper mold 1 keep sliding
Cooperation, upper mold 1 keep concentric with lower die 2, and the lower end surface SR size of upper mold 1 and the upper surface SR difference of lower die 2 are equal to a gold
Belong to piece thickness.
6 bore section of positioning sleeve increases blank holder 3, and blank holder lower end surface position increases elastic component, elasticity member
Device is between blank holder and pedestal 5.
The elasticity component is spring 4.
The blank holder 3 is acted on by spring force, and upper surface can be higher by lower die 2, height difference need according to sheet metal at
The coefficient of elasticity of theoretical pressure-pad-force and spring when type is calculated.
The advantages of advantages of the present invention: comparing with prior art in first part's technical background, the solution of the present invention
It is: fold occurs when 1. membrane products can be avoided to form by blank body.2. not limited by equipment and mold volume, only
Can meet the needs of pressure-pad-force with a Rectangular Spring.

Specific embodiment
Technical solution of the present invention is further described below with reference to drawings and examples,
Referring to shown in attached drawing 1 and attached drawing 2, sheet metal is put between upper and lower mould, makes gold by the extruding force of upper and lower mold
Belong to piece and generates plastic deformation.Blank holder contacts before the molding of upper and lower mould with upper mold, and by the compressing force of single spring to gold
The straight portion for belonging to piece is compressed.When mold clamping, the molding to dimension D and R in attached drawing 5 and attached drawing 6, straight portion are realized
Due to the pressure by spring, type variable reduces.To avoid the corrugated generation of side straight portion.
A kind of circular foil member casted die mould with straight flange referring to attached drawing 1, mold include upper mold 1, lower die 2, pedestal 5,
Positioning sleeve 6；Positioning sleeve 6 is connected through a screw thread with pedestal 5, and outer circle and the holding of 6 inner circle of positioning sleeve of upper mold 1 are slidably matched, upper mold 1
Keep concentric with lower die 2.The lower end surface SR size of upper mold 1 and the upper surface SR difference of lower die 2 are equal to a sheet thicknesses.
6 bore section of positioning sleeve increases blank holder 3, and blank holder lower end surface position increases elastic component, elasticity member
Device is between blank holder and pedestal 5.
Elastic component can be changed to the organic materials such as spring or polyurethane.Or apply flanging by way of air pressure
Power.
Special construction is referring to 3 upper mold of attached drawing and 4 lower die of attached drawing.Shaping metal sheets size leans on the spherical surface size of upper die and lower die
Control.Sheet metal can be generated after die mould and be sprung back to a certain degree, and upper and lower mould size, which needs to verify repeatedly, can just obtain exact value.
It is acted on referring to 1 blank holder 3 of attached drawing by spring force, upper surface can be higher by lower die 2, and height difference is needed according to metal
The coefficient of elasticity of theoretical pressure-pad-force and spring when sheetmolding is calculated.Blank holder upper end is placed into before shaping metal sheets
Face position.Sheet metal straight portion and blank holder upper end face contact, upper mold 1 are straight to sheet metal with blank holder 3 first in downlink
Rim portion generates pressing force, comes downwards to before 2 upper surface of lower die, due to compression deformation of the spring, pressure-pad-force can be become larger.Upper mold
1 continues traveling downwardly, in generation of the die mould moment straight portion due to being avoided fold by pressing force effect.
