Definitions
- the present invention relates to a pressure forming method for a steel sheet on which embossing is formed. More specifically, the present invention relates to a pressure forming method of a steel plate on which embossing for manufacturing a product that requires strength such as a structural member or a reinforcing member of an automobile is formed.
- the heated steel sheet is hot-pressed with a mold (for example, “hot press”), so that the steel sheet is made into high-tensile steel by quenching with the mold.
- a technique called induction hardening has been developed (see, for example, Patent Document 1).
- induction hardening requires advanced know-how in quenching and cooling methods, and has not been widely used.
- hot presses have become widely used because they have relatively few such problems.
- the conventional hot press is a process in which the material is heated to a temperature lower than the melting point (about 950 ° C.) by a facility such as a heating furnace before pressing, and the material put between the upper and lower molds is formed by pressing.
- a product with a high strength of about 1500 MPa is obtained for quenching.
- Young's modulus is a low tensile strength iron called general steel.
- the static rigidity is determined depending on the thickness after the material is determined. Therefore, there is a case where the sheet cannot be easily made thin even if the strength is increased. Therefore, hot presses can be applied only to products that originally have a sufficient margin for rigidity, or parts that have room to supplement rigidity by design methods such as expansion of cross-sectional area and cross-sectional shape. I was sorry.
- a steel plate with embossing is formed because a cooling medium passage to which a cooling medium is supplied is formed in a portion close to the cavity of the mold, and the cavity forming surface of the cooled mold is brought into contact with the plate material to exchange heat. In this case, there is a problem that the contact area is small, heat exchange cannot be expected, and the quenching conditions are not satisfied.
- an object of the present invention is to make it possible to cool an embossed steel plate under conditions sufficient for quenching.
- the present invention is a pressure forming method of a steel plate on which embossing is formed, and the steel plate is placed in a cavity formed by an upper mold and a lower mold, and is pressed by clamping the mold.
- the steel sheet is quenched by supplying and circulating a cooling medium.
- the present invention can provide a pressure forming method of a steel plate on which embossing is performed so that even a steel plate on which embossing is formed can be cooled under conditions sufficient for quenching.
- FIG. 1 is a partial perspective view of a center pillar reinforcing member 1 which is a reinforcing member of an automobile after forming and forming a convex portion 2 forming an emboss
- FIG. 2 is a partial plan view of the center pillar reinforcing member 1.
- the center pillar reinforcing member 1 is formed of a plate made of a rectangular steel plate with a thickness of 0.8 mm to 2.2 mm, for example.
- a manufacturing method of the center pillar reinforcing member 1, that is, a pressure forming method of the center pillar reinforcing member 1 will be described.
- a large number of convex portions 2 are formed on the plate body 10 made of steel by embossing.
- the flat plate portions HM are formed in an array state so as not to remain linear between the two.
- planar view exhibits a regular hexagon, for example, and the longitudinal cross section which passes along the vertex which forms a diagonal is exhibiting circular arc shape.
- the convex portion 2 may have a circular shape in plan view and a vertical cross section having an arc shape.
- the plate 10 may be formed with a concave portion instead of the convex portion 2, or with a convex portion and a concave portion.
- the convex part 2 of the said plate 10 is formed as follows, for example. That is, the width W1 of the convex portion 2 of the plate 10 is, for example, 10 mm to 50 mm, and the convex portion 2 has a height H of the convex portion / width W1 of the convex portion, for example, 12% to 20%.
- the flat plate portion HM does not remain linearly between the convex portions 2, and the interval C between the convex portions 2 is an interval C / 2 and the width W 1 of the convex portion 2.
- it is formed to be 75% or less of the base width W2, which is the sum.
- the convex portions 2 as described above are formed on the plate body 10.
- the present invention is not limited to this, and other shapes (in a plan view shape, a cross-sectional shape, etc.) or other arrangements are possible.
- the convex portion or the concave portion formed on the plate 10 may have various forms.
- the plate 10 on which the convex portions 2 as described above are formed is heated to a temperature of, for example, 850 ° C. or higher by a facility such as a heating furnace before pressing, and does not reach the melting point (850 ° C. to 1100 ° C.).
- An austenite transformation is performed within the following range), and the upper die 3 and the lower die 4 having a cavity S, which is a predetermined die gap that follows the final shape of the center pillar reinforcing member 1 of the plate body 10. Mold inside.
- the upper and lower mold surfaces are provided with predetermined cavities S, most of the plate body 10 pressed by clamping is pressed into a desired shape, for example, a cross-section, without the projections 2 being crushed. Is formed into a U-shape.
- a circulation pump not shown
- the cooling medium passages 5 and 6 are formed to communicate with the cavity S through the communication passages 7 and 8, respectively.
- the cooling medium passages 5B and 5C are communicated with 5D and 5E, and 5F and 5A are communicated, and the cooling medium passages 6B and 6C are communicated with 6D and 6E, and 6F and 6A are communicated.
- a plate body 10 having convex portions 2 formed between the upper press mold 3 and the lower press mold 4 is placed, and the mold is clamped and pressurized as shown in FIG. Then, the plate 10 is bent into a shape that follows the final shape.
- the plate body 10 is formed from the temperature of 630 ° C. or higher by pressing the upper mold 3 and the lower mold. Tighten, cool and start quenching. That is, after the mold clamping, the leftmost cooling medium passage 5A ⁇ communication passage 7A ⁇ cavity S ⁇ communication passage 7B ⁇ cooling medium passage 5B ⁇ cooling medium in FIG. Passage 5C ⁇ communication passage 7C ⁇ cavity S ⁇ communication passage 7D ⁇ cooling medium passage 5D ⁇ cooling medium passage 5E ⁇ communication passage 7E ⁇ cavity S ⁇ communication passage 7F ⁇ cooling medium passage 5F ⁇ cooling medium passage 5A.
- the plate body 10 placed in the cavity S of the upper press mold 3 and the lower press mold 4 is formed with a large number of convex portions 2 so that the cavity forming surfaces of the upper press mold 3 and the lower press mold 4 are formed. Even if the contact area is small, it is cooled sufficiently from both sides with circulating cooling water and quenched. This quenching is appropriately performed according to the type of the plate body 10 until the plate body 10 reaches a necessary temperature.
- the cooling water is circulated, the temperature of the plate 10 is decreased by 30 ° C. or more per second, and quenching is performed until the plate 10 reaches a temperature of 300 ° C. or less.
- the cooling water is discharged from the inside of the circulation path, and when the discharge is finished, the mold is opened, and the center pillar reinforcing member 1 as a martensitic transformed product is taken out from the cavity S.
- convex portions as in the above embodiment, the required rigidity can be ensured without increasing the plate thickness, and even a steel plate with convex portions formed can be cooled under conditions sufficient for quenching. it can.
- each cooling medium passage 5 and 6 are formed in the upper press mold 3 and the lower press mold 4, and each cooling medium passage 5 and 6 includes the cavity S and each communication passage 7 and 8.

- This is a method for pressing steel plates with embossing, and is used when manufacturing products that require strength, such as automobile structural members and reinforcing members.
