Specific embodiment
In the accompanying drawings, represent same or similar element using same or similar label or with identical or The element of similar functions.Embodiments of the invention are described in detail below in conjunction with the accompanying drawings.
In the description of the invention, term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear", " left side ", The orientation or position relationship of the instruction such as " right side ", " vertical ", " level ", " top ", " bottom " " interior ", " outward " It is, based on orientation shown in the drawings or position relationship, to be for only for ease of the description present invention and simplify description, and Be not indicate or imply meaning device or element must have specific orientation, with specific azimuth configuration and Operation, therefore it is not intended that limiting the scope of the invention.
Fig. 1 is the schematic diagram of the cavity plate of covering drawing die according to an embodiment of the invention.Institute in figure It is shown as the cavity plate 1 of covering drawing die.There is raised corner 2 on cavity plate 1, raised corner 2 has The outer side edges 2a for the closing on outside and inner side edge 2b for closing on inner side.Outer side edges 2a and the big body phases of inner side edge 2b It is mutually vertical.It is pointed out that raised corner refers to raised corner on final stamping forming covering. Actually to cavity plate 1 itself, the corner that raised corner 2 is generally downwardly concave.But, in order to just In description, in the present invention, by the recess for forming the raised corner on product on punch-pin 1, referred to as Raised corner.
Covering drawing die according to an embodiment of the invention includes cavity plate 1 and holding pad (not shown). The covering has raised corner, for example, the covering is wheel cover.In the cavity plate 1 and holding pad On the non-product position for closing on the raised corner portion at be provided with bead, to control the feeding of plate.
It is provided with the non-product position for closing on the raised corner portion on the cavity plate 1 and holding pad Bead, the bead includes that the basic bead 3a being sequentially connected, adjustment bead 3b and end are drawn Prolong muscle 3c.Basic bead 3a, adjustment bead 3b and the end generally linear extensions of bead 3c, But extension can also be bent, for example, for circular arc extends.In the case of bending, between each section of bead Angle refers to then the angle of line between each section of bead end points.
Bead refers to, in the muscle set by the non-product position of mould, to be generally arranged at cavity plate and holding pad On.Bead plays very important effect in drawing.Referring to Fig. 2, basic bead 3a substantially along And extend parallel to cavity plate outboard wheel profile.Additionally, the cross sectional shape of bead is also very important. In one alternative, the cross sectional shape of the bead is square.In another alternative embodiment, institute It is semicircle to state the cross sectional shape of bead.Semicircular bead has easy to process, compression effect good Advantage.
Found by contrast test, the bead of inside lateral bending folding of the invention, with preferably having prevented Wrinkle effect.That is, it is preferable that, the inside lateral bend of bead.Inner side herein refers to close on most The side of finished product.
Advantageously, basic bead and its extended line exist with raised corner 2 closest to the distance at place Between 10mm-20mm.
Advantageously, the angle between the outer side edges in adjustment bead 3b and raised corner is less than or equal to 15 Degree, parallel to the basic bead 3a, adjustment bead 3b draws end bead 3c with basic respectively Prolong muscle 3a, the end bead 3c circular sliding slopes.Due to adjustment bead 3b and raised corner 2 Angle between outer side edges 2a is smaller, general parallel orientation, thus, it is possible to relatively evenly control raised corner 2 The plate feeding at place, advantageously reduces or even eliminates plate corrugation.
In a preferred embodiment, extend to the end bead 3c from the adjustment bead 3b Direction on, the distance between the adjustment bead 3b and the outer side edges in the raised corner are dull gradually Increase.This is conducive to the smooth shaping in raised corner.It is outstanding that this has the raised inclination angle being added in raised corner Its is favourable.It may further be preferable that the connection between the adjustment bead 3b and basic bead 3a Half of the radius of circular arc more than the connection circular arc between the outer side edges 2a and inner side edge 2b in the raised corner 2 Footpath.
Referring to Fig. 2, removable cavity plate adjustment insert 4 is provided with cavity plate 1, wherein, the adjustment Bead 3b is at least partially disposed in the cavity plate adjustment insert 4.Preferably, the whole adjustment Bead 3b is arranged in the cavity plate adjustment insert 4.It is thus possible to change different inserts to exchange The set location of whole bead 3b is adjusted.In an alternative embodiment, end bead is also provided with In cavity plate adjustment insert 4.It is understood that cavity plate adjusts the concrete shape and mounting structure of insert 4 Any appropriate configuration can as needed be used.Alternatively, it is also possible to set adjustment insert on holding pad.
Preferably, the minimum range between the cavity plate adjustment insert 4 and final products edge is more than or equal to 8 Millimeter.
Preferably, on the cavity plate, bead is arranged into convex, and on the holding pad, correspondence is drawn Prolong muscle concavity arrangement.It is understood that being also correspondingly formed with holding pad and bead on cavity plate Corresponding correspondence bead.
Bead on cavity plate 2 is advantageously set with welding manner.So as to be easy to this in the holding pad On be provided with parallel at least two correspondences adjustment beads, the cavity plate 1 is provided with an only adjustment Bead 3b, when in use, on adjustment bead 3b on the cavity plate 1 and the holding pad at least A cooperation in two correspondence adjustment beads.
In one alternate embodiment, at least two correspondences adjustment bead phase on the holding pad Mutually it be arranged in parallel.For example, at least two correspondences adjustment bead can be with spaced set.The spacing For example, 3 millimeters.In another alternative embodiment, on holding pad it is described at least two correspondence adjustment muscle it Between into uniform angle interval setting.For example, basic with corresponding in described at least two correspondence adjustment beads Bead junction is intersected, and the angle that adjacent correspondence is adjusted between bead is 5 degree.Correspondence adjustment drawing The particular number of muscle, can be arranged as required to.
Preferably, if the adjustment bead 3b of the cavity plate 1 is right with least two on the holding pad One in bead should be adjusted to coordinate when carrying out drawing, in the covering there is raised corner 2 to occur Wrinkle, the adjustment bead 3b on the processing removal cavity plate, and another adjustment bead of setting is welded, Coordinated with adjustment bead another corresponding on the holding pad.
In the present invention, the bead of raised corner positions is closed on by setting to control the feeding of plate, And adjustment bead is substantially parallel to the outer side edges in raised corner, thus, it is possible to preferably control raised angle Charging at portion, thus reduces or even avoids corner wrinkling.
It is last it is to be noted that:The above embodiments are merely illustrative of the technical solutions of the present invention, rather than right Its limitation.It will be understood by those within the art that:Can be to the technology described in foregoing embodiments Scheme is modified, or carries out equivalent to which part technical characteristic;These modifications are replaced, The spirit and scope of the essence disengaging various embodiments of the present invention technical scheme of appropriate technical solution are not made.
