Description

Technical Field

[0001] The utility model relates to the technical field of stamping forming dies, and more specifically to a side outer panel forming tool. Background Art

[0002] The traditional stamping process usually includes four steps: 1. Drawing process, in which most of the appearance of the part is formed; 2. Trimming process, to remove excess waste; 3. Shaping process, to shape the surface of the part that fits with other parts of the car body and overlaps and welds; 4. Punching process, to punch out all the holes that need to be punched, so that the part is formed.

[0003] Among the large-scale exterior covering parts of automobiles, the stamping process of the side panel is the most difficult to form and has the most complex stamping die structure. For different parts of the side panel, each process corresponds to its own forming process scheme. Among them, the flange surface forming where the upper crossbeam overlaps the rear windshield is usually achieved by the following schemes: 1. Drawing the appearance surface; 2. Trimming; 3. Oblique punching and shaping of the flange surface. This scheme can successfully manufacture a side panel with only one step flange surface. However, if there is a side panel with two step flange surfaces, due to the inconsistent depths of the two steps, when performing the third process of oblique punching and shaping, the shaping mechanism first touches the part used to form the secondary step, and then touches the part used to form the primary step. This sequence difference causes uneven stress at the intersection of the steps of the part, resulting in wrinkles and waves in the part forming and deformation of the appearance surface, affecting the quality of the part.

[0004] For example, the prior art discloses a movable insert shaping mechanism and shaping method, the shaping mechanism includes a punch provided on the lower die body, a material pressing core and a shaping insert for shaping the sheet metal relative to the punch connected to the upper die body, and a punching mechanism for punching with the upper die body, the shaping insert is provided with a through hole corresponding to the punch, and the shaping insert is connected to the upper die body through a floating mechanism. In this scheme, the shaping insert is shaped in place at one time, and a side panel with only one step flange surface can be smoothly manufactured. However, if there is a side panel with two step flange surfaces, due to the inconsistent depths of the two steps, when performing oblique punching shaping, the shaping mechanism first touches the part used to form the secondary step, and then touches the part used to form the primary step. This sequence difference causes uneven stress at the intersection of the steps of the part, resulting in wrinkles and waves in the formed part and deformation of the appearance surface, affecting the quality of the part.

[0032] The above-mentioned side panel forming tool is used to shape the part 9 that has been drawn and trimmed. The side panel has a first step 91 and a second step 93.

During the first shaping, the height difference between the first step 91 and the sinking part 92 is small, which can reduce the wrinkling, wave and appearance deformation of the part 9 caused by the stress imbalance at the intersection of the first step 91 and the sinking part 92. Since the sinking part 92 is first formed on the first shaping die, the shaping height when the sinking part 92 is formed into the second step 93 can be reduced, and the appearance deformation caused by the material flow when the shaping amount is too large can be reduced. This embodiment can avoid wrinkling, wave and appearance deformation when forming the side panel with two steps of different depths, and ensure the quality of the part 9.

[0033] like Figure 1 , Figure 2 As shown, the first shaping mold includes a first upper mold 1, a first lower mold 2, a first pressure plate 3 and a first side shaping mechanism 4. The first upper mold 1 and the first pressure plate 3 can respectively move up and down along the first lower mold 2. The first pressure plate 3 cooperates with the first lower mold 2 to clamp the part 9. The first upper mold 1 is provided with a first driving seat 11.

Among them, the first lower die 2 is provided with a first die and a second die, and the first side shaping mechanism 4 is provided with a first punch and a second punch, the first punch cooperates with the first die to form the first step 91, and the second punch cooperates with the second die to form the sinking part 92.

[0036] Embodiment 2

[0037] This embodiment is similar to the first embodiment, except that Figure 4 , Figure 5 As shown, the second shaping mold includes a second upper mold 5, a second lower mold 6, a second pressure plate 7 and a second side shaping mechanism 8. The second upper mold 5 and the second pressure plate 7 can respectively move up and down along the second lower mold 6. The second side shaping mechanism 8 is connected to the second upper mold 5. The second pressure plate 7 cooperates with the second lower mold 6 to clamp the part 9. The second lower mold 6 is provided with a second driving seat 61. The second driving seat 61 is connected to the second upper mold 5 to enable the second upper mold 5 to move and push the second side shaping mechanism 8. The second side shaping mechanism 8 cooperates with the second lower mold 6 to form the sinking portion 92 into a second step 93.

[0038] Specifically, it also includes a second press, which includes a second machine platform and a second slide block located above the second machine platform, the second slide block is slidably connected to the second machine platform, the second lower mold 6 is installed on the second machine platform, and the second upper mold 5 and the second pressing plate 7 are hoisted and connected to the second slide block respectively.

[0039] During implementation, the part 9 formed with the first step 91 and the sinker 92 is placed on the top of the second lower die 6, and the second pressing plate 7, the second upper die 5 and the second side shaping mechanism 8 are moved downward by the second sliding block. The second pressing plate 7 first contacts the part 9 and cooperates with the second lower die 6 to clamp the non-machined surface of the part 9. The second upper die 5 continues to move downward, and the second driving seat 61 contacts and squeezes the second upper die 5. The second side shaping mechanism 8 moves and squeezes the part 9 through the second upper die 5. When the second side shaping mechanism 8 moves into place, the second side shaping mechanism 8 cooperates with the second lower die 6 to form a second step 93.

[0040] Among them, Figure 4As shown, the second driving seat 61 is provided with a first inclined surface 611, the second upper mold 5 is provided with a second inclined surface 51, and the first inclined surface 611 cooperates with the second inclined surface 51. During implementation, through the cooperation of the first inclined surface 611 and the second inclined surface 51, when the second upper mold 5 contacts the second driving seat 61 and continues to move downward, the second inclined surface 51 slides relative to the first inclined surface 611. Since the first inclined surface 611 is fixed, the second upper mold 5 provided with the second inclined surface 51 moves in the horizontal direction while moving downward, pushing the second side shaping mechanism 8 to extrude the part 9.

[0041] Embodiment 3

[0042] This embodiment is similar to the second embodiment, except that Figure 4 , Figure 7 As shown, the second side shaping mechanism 8 includes a body 81, a side pressure insert 82 and a side shaping insert 83. The second upper die 5 can contact the body 81 and drive the body 81 to move. The side pressure insert 82 is connected to the body 81 through a pressure spring 84, and the side shaping insert 83 is fixedly connected to the body 81. During implementation, the body 81 is driven to move, the side pressure insert 82 first contacts the part 9, and the pressure spring 84 provides pressure to press the first step 91 of the part 9 against the second lower die 6. The body 81 continues to move, and the side shaping insert 83 contacts and squeezes the part 9. During this process, the pressure spring 84 is gradually compressed. When the body 81 moves into place, the shaping is completed, and the sinking part 92 of the part 9 is formed into the second step 93.

[0043] like Figure 7 As shown, the second side shaping mechanism 8 further includes a limiting column 85, one end of which is connected to the body 81, and the other end of which is engaged with the side pressure material insert 82. The side pressure material insert 82 is provided with a limiting hole 86, and the limiting column 85 is slidably penetrated through the limiting hole 86. In this embodiment, the limiting column 85 is engaged with the side pressure material insert 82 to prevent the side pressure material insert 82 from falling off the body 81, and the side pressure material insert 82 is limited. At the same time, the side pressure material insert 82 can be guided by the cooperation of the limiting column 85 and the limiting hole 86.

[0044] like Figure 7As shown, the body 81 is also provided with a punch 87, and the side pressure material insert 82 is provided with a processing hole 88, and the punch 87 is slidably penetrated in the processing hole 88. During implementation, the body 81 is driven to move, and the side pressure material insert 82 first contacts the part 9, and provides pressure through the pressure spring 84, pressing the first step 91 of the part 9 against the second lower die 6, and the body 81 continues to move, and the side shaping insert 83 contacts and squeezes the part 9 to start shaping. During this process, the pressure spring 84 is gradually compressed, and the body 81 continues to move, and the pressure spring 84 continues to compress, and the punch 87 gradually extends from the processing hole 88 to start punching. When the body 81 moves into place, the sinking part 92 of the part 9 is formed into the second step 93 and the side punching is completed at the same time. Since the second step 93 is first shaped into a sinking hole by the first shaping die and then shaped into place by the second shaping die, the shaping amount is small during the second shaping, which reduces the material flow and avoids the phenomenon of hole position deformation and other appearance surface deformation during side punching.

In order to make the description concise, not all possible combinations of the above-mentioned technical features are described.
