It is platy structure to state molding concave die 8, and top has the projection portion of triangular structure, and the two sides of the projection portion are recessed
Arcuate structure, the molding concave die 8 are vertically arranged, and the first cavity plate type face 10 is stretched out on the top of the molding concave die 8, is had into
Type cavity plate 8 forms the intermediate projections structure of preforming sheet blanks, passes through stretching for the first cavity plate type face 10 and molding concave die 8
A preforming cavity plate type face with intermediate projections is collectively formed in the type face for going out part；The upper die holder includes the first punch-pin 3,
The bottom of first punch-pin 3 matches with preforming cavity plate type face and is correspondingly arranged.Two locating pieces 9 are set with blanking piece spacing
It sets, and includes U-shaped gap shape structure on the locating piece 9, blanking piece is positioned by U-shaped gap shape structure and is arranged, passes through two
A locating piece 9 carries out plate the positioning of four corners, ensures that its molding is accurate, and the first cavity plate type face 10 is U-shaped shape,
And the open end in the first cavity plate type face 10 is flaring arcuate shape, and it is flared the U-shaped gap shape of arcuate shape and locating piece
Structure connects.When positioning, blanking piece is supported by two flaring arcuate shapes on the first cavity plate, and at the same time, it is closing
When mould, the edge of blanking piece both sides is formed along the flaring arcuate shape to be bent.First cavity plate type face 10 of U-shaped shape, it is curved
Pars convoluta is arc, and the length of the symmetry axis of U-shaped shape to the bending section is less than the perimeter of edge rolling, about 3/4 or so, ensure in advance at
The plate of type forms tool, and there are two the plate side edges of arc warpage, to facilitate subsequent edge rolling molding procedure.
The outer sheath of first cavity plate 7 be equipped with stripper 4, the stripper 4 by several resetting springs 11 relatively under
1 up and down displacement of template, stripper 4 supports blanking piece, under die opening state, 4 support blanking piece of the stripper, and the discharging
The upper surface of plate 4 is higher than preforming cavity plate type face, and less than the upper surface of locating piece 9.When molding, stripper with upper die holder fortune
It is dynamic and move down, in die sinking, by stripper jack up it is preforming after sheet blanks, prevent it to be adhered on the first cavity plate, simultaneously
Also preforming sheet blanks can rapidly be taken out.
As shown in attached drawing 4, attached drawing 8 to attached drawing 11, the edge rolling forming module includes the second cavity plate, slide 16, inclined wedge 17
With the second punch-pin, second cavity plate includes the second cavity plate A20 being disposed adjacent and the second cavity plate B28, and second cavity plate is solid
Fixed to be arranged in lower template 1, second cavity plate is correspondingly arranged with the second punch-pin for being arranged in 2 bottom of cope plate, and described second
Punch-pin include the second punch-pin A21 and the second punch-pin B22, the second punch-pin A21, the second punch-pin B22 respectively with the second cavity plate
A20, the second cavity plate B28 are correspondingly arranged, by two groups of punch-pin cavity die structures respectively to the two side walls of preforming sheet blanks into
Row edge rolling is processed, and the outer sheath of the second punch-pin is equipped with holding pad 12, is compressed to preforming sheet blanks, is prevented from loosening and be moved
Position is disposed with slide 16 and fixed seat 19 outward from the side of second cavity plate, and the slide 16 is with setting in upper mold
The inclined wedge 17 of 2 bottom of plate is equipped with, and side is provided in the fixed seat 19 and takes out component 24, the slide 16 takes out component by side
24, inclined wedge 17 slides between the second cavity plate and fixed seat 19；It is provided with semicircle side on the slide 16 and pushes into type type face 26,
The side pushes into type type face 26 and crimps preforming sheet blanks, and preforming sheet blanks are by slide 16 relative to the second cavity plate
It is mobile, so that preforming sheet blanks is bent to circular configuration.Side is carried out by the interaction of inclined wedge and slide to push away, and makes sheet blanks
Side wall be crimped, it is simple in structure, it is easy to operate, be swift in motion, and ensure the dynamics that enough sides pushes away.
The side pushes into type type face 26 and is arranged in slide 16 towards the side of the second cavity plate, and second punch-pin is towards slide
16 side is provided with secondary edge rolling type face 27, and it is equal that the pair edge rolling type face 27 pushes into the radius of curvature in type type face 26 with side,
When slide 16 and the second cavity plate contact, the pair edge rolling type face 27 pushes into type type face 26 with side and engages, and preforming plate
The curving of part forms circular shape.Molding plate is oriented to by secondary edge rolling type face 27, while ensureing edge rolling
Molding, the bottom end in secondary edge rolling type face with it is preforming when plate middle section triangular hill top clearance be arranged, in edge rolling
In the process, it is not only limited by the stroke of slide, also the side wall body of plate is limited by the protrusion, prevents from becoming
Anisotropic shape in shape and reduction forming process.
By the second punch-pin, the second cavity plate and slide, a circular type face is formed, is moved to the second cavity plate in slide 16
When, the side wall of preforming sheet blanks is squeezed by the end portion in the concave face on slide, so that it is generated and is directed toward circle
The vectorial force at arc center promotes sheet metal bending edge rolling, easy to operate, and molding is rapid, and molding effect is good, ensure that repetition adds
Uniformity, the consistency of work.
The side pushes into the radius of curvature in type type face 26 more than the radius of curvature for the circular shape that sheet blanks curl into, side
The initiating terminal in type type face 26 and the lower surface of plate are pushed into same level height, when slide 16 is slided and squeezed, side pushes into
Type type face constantly generates abrasion with plate friction, and diameter of a circle is rolled up after abrasion and will produce bigger than normal and irregular cycle, facilitates processing
When find in time, and be adjusted replacement.
Further include block 18, second cavity plate 20 is arranged by fixed plate 14 in lower template, the fixed plate 14
Side fitting is provided at least one block 18, and the block is fixed in lower template, the moving direction of the slide 16
Perpendicular to the block 18.Since in edge rolling, lateral force is larger, easily shifts the second cavity plate, can be increased by several blocks 18
Add the stability of the second cavity plate.
The above is only the preferred embodiment of the utility model, it should be pointed out that：For the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
