Description
Technical field
It is the utility model relates to stamping die field, in particular to a kind of for forming the stamping die of vehicle seat connection
Group.
Background technique
Stamping die is also one kind of mold, is used for batch forming part.Itself and injection mold, the maximum area of die casting
Be not, material is not necessarily to heat and soften before shaping, i.e. plastic at room temperature, so have it is energy saving, when molding without
Need to consider material cool and solidify, without setting oil cooling or water cooling system the advantages that.
Existing a kind of connector for vehicle seat, as shown in Figure 1, it includes orthogonal riser 101 and transverse slat
102, riser 101 is connected with the end of transverse slat 102, and the two junction is connected with the wing plate 103 of outwardly convex 3.Vertical version and cross
Plate 102 is folded upward at backwards to the side of wing plate 103, forms the first flange 104, and the two other side is then folded upward at, and forms the
Two flange 105 have third flange 106 around wing plate 103.Wherein the height of the first flange 104 is smaller, the height of the second flange 105
Larger, the height maximum of third flange 106 is spent, and is greater than the width of wing plate 103.The junction of transverse slat 102 and the second flange 105
It is additionally provided with two reinforcing ribs 107.
The small volume of this vehicle seat connector, thickness is little, mostly uses the raw material using sheet greatly, passes through punching
Compression mould carries out processing and fabricating.In process, because the height of the second flange and third flange is larger, transition between the two
Section distance from top riser and transverse slat farther out, along with the radius of curvature very little of changeover portion, so that material molding mistake at this
Biggish stretcher strain is had in journey.If each flange of straight forming, the changeover portion between the second flange and third flange holds
Yi Yin, which is stretched, excessively acutely to crack, it is difficult to form qualified vehicle seat connector.
Utility model content
