Description

Technical Field

[0001] The utility model relates to the technical field of beam part processing, in particular to a beam part with a flange, a forming die and a vehicle. Background Art

[0002] After the beam part formed by stamping is unloaded, the workpiece will produce reverse elastic recovery deformation, commonly known as springback. Springback is a technical problem faced in the processing and forming of beam parts, especially structural parts made of ultra-high strength steel. In order to control stamping springback, currently, the springback control at the process design end is mainly carried out through springback compensation technology. One is to add a sizing process and use a sizing die for side sizing; the other is through the draw reverse rib forming technology, by adding a reverse rib on the outer side of the workpiece flange to offset the difference between the internal and external tensile and compressive stresses, thereby reducing springback. However, these two technical solutions have problems of increased production processes and low material utilization rate, resulting in an increase in the cost of a single part. When the part is applied to a vehicle, it will greatly increase the cost of the entire white body. Content of the Utility Model

[0032] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0033] Reference is made below to the attached Figures 1 - 6 Describe a beam-like part according to an embodiment of the present invention.

[0034] When the beam-like part 100 is applied to a vehicle, it is used to lap with a counterpart to form the vehicle body.

[0035] Refer to Figures 1 - 3 , the beam-like part 100 according to an embodiment of the present invention includes a beam-like part body 10 and a flange 20 bent from the beam-like part body and extending in a direction away from the beam-like part body. A plurality of convex ribs 21 for preventing springback are provided on the flange 20, and the plurality of convex ribs 21 are uniformly arranged on the flange 20.

[0036] Specifically, the beam-like part body 10 and the flange 20 are integrally formed by stamping. A plurality of uniformly arranged convex ribs 21 are provided on the flange 20, and the convex ribs 21 are used to prevent springback after the parts are formed. Therefore, the beam-like part of this embodiment can effectively improve the plastic deformation generated after the parts are formed due to the formation of a plurality of uniformly arranged convex ribs on the flange 20, especially for beam-like parts above the high-strength steel level. The beam-like part of this embodiment can avoid the problem of material waste existing in the existing process by providing a plurality of convex ribs on the flange, thereby reducing the blank size, improving the material utilization rate of the product, reducing costs; it can also reduce a sizing process, reduce the use of sizing dies, simplify the die structure, reduce processes, and achieve a good springback control effect.

[0037] To achieve the object of the present invention, the convex ribs 21 are uniformly arranged on the flange 20, which means that the distance between adjacent two convex ribs 21 is equal, or the distance between adjacent two convex ribs 21 is approximately equal.

[0038] As an embodiment, the number of the convex ribs 21 ≥ 2. In the thickness direction of the flanging, the flanging 20 includes a first surface and a second surface. The convex rib 21 is a protrusion formed by being recessed inward from the second surface and protruding toward the first surface. The maximum height of the protrusion from the first surface is h1, and 0.1 mm ≤ h1 ≤ 0.5 mm; the maximum height of the recess from the second surface is h2, and 0.1 mm ≤ h2 ≤ 0.5 mm.

[0039] The number of the convex ribs 21 can be set according to the width requirement of the flanging 20 so as to be evenly arranged on the flanging 20. The flanging 20 includes a first surface and a second surface. As Figure 1 shown, the first surface can be the lower surface of the flanging, and the second surface can be the upper surface of the flanging; or, the first surface is the upper surface of the flanging, and the second surface is the lower surface of the flanging.

[0040] The convex rib 21 is a protrusion formed by being recessed inward from the second surface and protruding toward the first surface. The maximum height of the protrusion from the first surface is h1, that is, the maximum height distance between the convex rib 21 and the first surface is h1, and 0.1 mm ≤ h1 ≤ 0.5 mm. The maximum height of the recess from the second surface is h2, that is, the maximum height distance between the recess and the second surface is h2, and 0.1 mm ≤ h2 ≤ 0.5 mm. The purpose of such a setting is to improve the stability when the beam-like part 100 is lapped with the mating part, and to avoid the poor welding problem caused by too large a gap in the lap of the beam-like part due to too high a convex rib height when lap-welding with the mating part. Thus, while effectively reducing costs, the quality of the parts is ensured; when the beam-like part is applied to a vehicle, the stability of the lap structure of the beam-like part can be improved, and while reducing costs, the quality of the vehicle is ensured, so that the vehicle meets the increasingly stringent collision regulations.

[0041] As an embodiment, for example, as Figure 2 and Figure 3 shown, a first arc edge 30 is formed between the beam-like part body 10 and the flanging 20. The first arc edge 30 is located between the beam-like part body 10 and the flanging 20 and serves as a transition between the beam-like part body 10 and the flanging 20. The flanging 20 includes a first side edge and a second side edge. The first side edge is located at the adjacent position of the flanging 20 and the first arc edge 30, and the second side edge is located at the outermost side edge of the flanging 20 away from the beam-like part body. The distance between the first side edge and the second side edge of the flanging is L0; wherein, the convex rib closest to the first side edge is the first convex rib 211, and the distance between the first side edge and the first convex rib 211 is L1; the convex rib closest to the second side edge is the second convex rib 212, and the distance between the second side edge and the second convex rib is L2; the ratio between L0 and L1 or L2 is: 0.02 ≤ L1 / L0 ≤ 0.5, 0.02 ≤ L2 / L0 ≤ 0.5.

[0042] In the width direction of the flanging 20, that is, from the side close to the beam - like part body 10 to the side far from the beam - like part body 10, the flanging 20 includes a first side and a second side. The first side is the adjacent side of the flanging 20 and the first arc - shaped side 30, and the second side is the outermost side of the flanging 20 far from the beam - like part body 10. The distance between the first side and the second side of the flanging 20 is L0, the distance between the first side and the first convex rib 211 is L1, and the distance between the second side and the second convex rib is L2. The ratio between the distance L0 and L1 or L2 satisfies the following conditions: 0.02 ≤ L1 / L0 ≤ 0.5, 0.02 ≤ L2 / L0 ≤ 0.5.

[0043] The ratio between the distance L0 and L1 or L2 satisfies the conditions: 0.02 ≤ L1 / L0 ≤ 0.5, 0.02 ≤ L2 / L0 ≤ 0.5. By setting this way, the arrangement of the convex ribs 21 on the flanging 20 is more reasonable, which can effectively improve the plastic deformation generated after the forming of the beam - like part. Especially for beam - like parts above the high - strength steel level, by setting multiple convex ribs on the flanging, the material waste problem existing in the existing process can be avoided, thereby reducing the blank size, improving the material utilization rate of the product, and reducing the cost; it can also reduce a sizing process, reduce the use of sizing dies, simplify the die structure, reduce the process, and achieve a good springback control effect.

[0044] As an embodiment, among the multiple convex ribs 21, the distance between adjacent convex ribs is L3, and the width distance between the first side and the second side of the flanging 20 is L0. The ratio between L0 and L3 satisfies the relational expression 0.02 ≤ L3 / L0 ≤ 0.5.

[0045] The distance L3 between adjacent convex ribs and the width distance L0 between the first side and the second side of the flanging 20 satisfy the following conditions: 0.02 ≤ L3 / L0 ≤ 0.5. By restricting the ratio of the distance between adjacent convex ribs to the width of the flanging, the width and density of the convex ribs are reasonably limited, so as to effectively improve the springback problem in part processing and ensure the stability when the beam - like part is lapped with the mating part.

[0046] According to some embodiments of the present utility model, the convex rib 21 is configured as an arc - shaped protrusion. The arc radius of the arc - shaped protrusion is R3, and 1 mm ≤ R3 ≤ 5 mm. On both sides where the arc - shaped protrusion intersects with the first surface, a second arc - shaped side and a third arc - shaped side are respectively formed. The arc radius of the second arc - shaped side is R1, and 0.5 mm ≤ R1 ≤ 5 mm. The arc radius of the third arc - shaped side is R2, and 0.5 mm ≤ R2 ≤ 5 mm.

[0047] The convex rib 21 is configured as an arc-shaped protrusion, which can facilitate the processing of the mold and also enable the stamped parts to have a better anti-rebound effect; the radius of the arc of the arc-shaped protrusion is R3, and 1 mm ≤ R3 ≤ 5 mm, so that the formed beam-like parts are more firmly welded to the opponent parts during application. Since the convex rib is formed by protruding from the second surface to the first surface, therefore, a second arc-shaped side and a third arc-shaped side located on the left and right sides of the protrusion are formed between the arc-shaped protrusion and the first surface. The radius of the arc of the second arc-shaped side is R1, and the size of the radius of the arc of the second arc-shaped side is preferably 0.5 mm ≤ R1 ≤ 5 mm. The radius of the arc of the third arc-shaped side is R2, and the size of the radius of the arc of the third arc-shaped side is preferably 0.5 mm ≤ R2 ≤ 5 mm.

[0048] The above is only the best embodiment for limiting the circular radius, and it is not an absolute limitation on the size of the arc radius. Any adjustment of the arc radius size can be made according to the actual application needs based on the purpose of the present invention; similarly, the sizes of L0, L1, L2, and L3 can also be adaptively adjusted according to the implementation application needs.

[0049] As an embodiment, the beam-like part body 10 includes a body top surface 11 and a bent edge 12, and the included angle between the body top surface 11 and the bent edge is greater than 0° and less than 180°.

[0050] The bent edge 12 is bent from the body top surface 11 to the side by an arbitrary angle. In this embodiment, there are two bent edges, and the two bent edges are respectively located on the opposite sides of the body top surface. For example, a beam-like part with a cross-section in the shape of a "several" character.

[0051] According to the forming die 200 of the second aspect embodiment of the present invention, the forming die 200 is used for stamping the beam-like part described in the first aspect embodiment above.

[0052] Referring to Figure 4 、 Figure 5 , the forming die 200 includes a first die body 210 and a second die body 220; the second die body 220 cooperates with the first die body; the first die body 210 has a first flanging forming part 213, and the second die body 220 has a second flanging forming part 221. The first flanging forming part 213 and the second flanging forming part 221 are used to cooperate to process the flanging of the beam-like part in the first embodiment above. The first flanging forming part 213 is provided with a plurality of convex ribs evenly distributed, and the second flanging forming part 221 is provided with a plurality of grooves corresponding thereto. Based on the purpose of the present invention, it can also be that the first flanging forming part 213 is provided with a plurality of grooves evenly distributed, and the second flanging forming part 221 is provided with a plurality of convex ribs corresponding thereto.

[0053] As an embodiment, the first die body 210 includes a first flanging forming portion 213 and a punch core 214. The punch core 214 is used to process and form the body of the beam-like part, and the first flanging forming portion 213 and the punch core 214 are an integral body. Alternatively, the first flanging forming portion 213 is a blank holder of the first die body 210, and the blank holder is independent of the punch core 214 and together they form the first die body 210.

[0054] In the forming die of this embodiment, by being set to process the beam-like part of the above first aspect embodiment, during processing, when the first die body is fixed on the stamping bed as the lower die, the second die body is installed on the upper die, and the second die body is driven to move by the upper die slider to process and form the blank placed on the first die body. By providing a first flanging forming portion 213 on the first die body 210 and a second flanging forming portion 221 on the second die body 220, the formed part has a body top surface 11 and a bent edge 12; by providing a plurality of convex ribs or grooves evenly distributed on the first flanging forming portion 213 and a plurality of corresponding grooves or convex ribs on the second flanging forming portion 221, the formed beam-like part has a flanging, and there are a plurality of evenly arranged convex ribs on the flanging. The convex ribs act as draw beads during stamping production to lock the product flanging after stamping and avoid product springback; at the same time, since the flanging is an essential part of the beam-like part product, it does not need to be cut as waste, and the material utilization rate can be improved. Therefore, the forming die of this embodiment has a plurality of convex ribs evenly distributed on the flanging of the beam-like part, so the sizing process in the stamping process can be saved, the processing efficiency of the part can be effectively improved, the material utilization rate can be improved at the same time, and the processing cost of the part can be effectively reduced.

[0055] The vehicle according to the third aspect embodiment of the present invention includes the beam-like part of the above first aspect embodiment.

[0056] Specifically, the beam-like part 100 includes a beam-like part body 10 and a flanging 20 that extends from the beam-like part body and bends away from the beam-like part body. A plurality of convex ribs 21 for preventing springback are provided on the flanging 20, and the plurality of convex ribs 21 are evenly arranged on the flanging 20. The number of convex ribs 21 ≥ 2. In the thickness direction of the flanging, the flanging 20 includes a first surface and a second surface. The convex rib 21 is a protrusion formed by being recessed inward from the second surface and protruding toward the first surface. The height of the protrusion from the highest point away from the first surface is h1, 0.1 mm ≤ h1 ≤ 0.5 mm; the height of the depression from the highest point away from the second surface is h2, 0.1 mm ≤ h2 ≤ 0.5 mm.

[0057] A first arc edge 30 is formed between the beam-like part body 10 and the flange 20. The first arc edge 30 is located between the beam-like part body 10 and the flange 20 and serves as a transition between the beam-like part body 10 and the flange 20. The flange 20 includes a first side edge and a second side edge. The first side edge is adjacent to the first arc edge 30 of the flange 20, and the second side edge is the outermost side edge of the flange 20 away from the beam-like part body. The distance between the first side edge and the second side edge of the flange is L0. Among them, the rib closest to the first side edge is the first rib 211, and the distance between the first side edge and the first rib 211 is L1. The rib closest to the second side edge is the second rib 212, and the distance between the second side edge and the second rib is L2. The ratio between L0 and L1 is: 0.02 ≤ L1 / L0 ≤ 0.5. The ratio between L0 and L2 is: 0.02 ≤ L2 / L0 ≤ 0.5. Among the multiple ribs 21, the distance between adjacent ribs is L3, and the width distance between the first side edge and the second side edge of the flange 20 is L0. The ratio between L0 and L3 satisfies the relationship 0.02 ≤ L3 / L0 ≤ 0.5.

[0058] According to an embodiment of the present invention, the rib 21 is configured as an arc-shaped protrusion. The cross-section of the arc-shaped protrusion is a circular arc. The radius of the circular arc of the arc-shaped protrusion is R3, and 1 mm ≤ R3 ≤ 5 mm. Second arc edges and third arc edges are respectively formed on both sides where the arc-shaped protrusion intersects the first surface. The radius of the circular arc of the second arc edge is R1, and 0.5 mm ≤ R1 ≤ 5 mm. The radius of the circular arc of the third arc edge is R2, and 0.5 mm ≤ R2 ≤ 5 mm.

[0059] The beam-like part body 10 includes a body top surface 11 and a bent edge 12. The included angle between the body top surface 11 and the bent edge is greater than 0° and less than 180°.

[0060] Refer to Figure 6 , when the beam-like part 100 is applied to a vehicle, the beam-like part 100 is welded to the first mating part 300 and the second mating part 400 to form a welded assembly and is connected into the white body of the vehicle. By designing and integrating multiple small and low ribs on the beam-like part 100, multiple ribs forming a wavy shape are processed on the forming die 200. Subsequently, during the stamping process, the ribs bite the flange on the die like nails, reducing its springback and also reducing waste usage. In particular, it is suitable for improving the stamping springback problem of parts above the high-strength steel level. In addition, setting the height of the ribs below 0.5 mm can avoid the problem of poor welding caused by too large a gap in the overlap welding of sheet parts due to too high a rib height when overlapping with the mating part. Therefore, the beam-like part of the present invention can effectively solve the problem of low utilization rate of stamping materials and can also significantly control the springback of ultra-high-strength steel.
