Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping technology, and in particular to a deep drawing stamping die for automotive sheet metal parts. Background Technology
[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. Its most obvious characteristic is that the parts have a uniform thickness after processing. Products processed by sheet metal processing are called sheet metal parts.
[0003] A search revealed that utility model patent CN220805190U discloses a deep-drawing stamping die for automotive sheet metal parts, comprising an upper mounting plate, multiple connecting pillars fixedly mounted on the lower surface of the upper mounting plate, a lower mounting plate fixedly mounted on the lower end of the connecting pillars, a formed part fixedly mounted on the lower mounting plate, a connecting shaft slidably connected to the upper mounting plate, an mounting sleeve rotatably mounted on the lower end of the connecting shaft, a movable plate fixedly mounted on the lower surface of the mounting sleeve, multiple through slots formed thereon, a driven gear fixedly mounted on the mounting sleeve, a driving gear provided on one side of the driven gear, the driving gear meshing with the driven gear, and a stamping assembly provided on the upper mounting plate.
[0004] Although the above-mentioned device can realize deep drawing and stamping of automotive sheet metal parts, in the actual stamping process, after the sheet material is stamped once, the area of the sheet material at the top of the movable plate will be reduced. At the same time, the part that passes through the slot due to stamping will not fit with the inner wall of the slot. At this time, because the sheet material after stamping lacks positioning, the sheet material is very easy to be misaligned inside the slot during the subsequent rotation of the movable plate, which leads to the inability to perform accurate stamping in the future, resulting in a reduction in stamping accuracy.
[0005] Therefore, it is necessary to invent a deep drawing and stamping die for automotive sheet metal parts to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a deep drawing and stamping die for automotive sheet metal parts. This die can position the sheet metal material before and after the first deep drawing and stamping process, thus preventing misalignment when it moves from the first stamping station to the second stamping station. This allows the subsequent deep drawing and stamping mechanism to accurately stamp the sheet metal material, effectively improving stamping accuracy. This addresses the problem mentioned in the background art where, after one stamping, the area of the sheet metal material at the top of the movable plate decreases, and the portion passing through the slot due to stamping does not adhere to the inner wall of the slot. Because the stamped sheet metal material lacks positioning, it is prone to misalignment within the slot during subsequent rotation of the movable plate, leading to inaccurate stamping and reduced stamping accuracy.
[0007] According to one aspect of this disclosure, the following technical solution is provided: a deep drawing and stamping die for automotive sheet metal parts, comprising:
[0008] Equipment frame, the equipment frame is used to install the deep drawing and stamping forming mechanism and the plate material transposition mechanism;

[0015] According to at least one embodiment of the present disclosure, a deep drawing stamping die for automotive sheet metal parts is provided, wherein a first upper die and a second upper die are fixedly disposed on both sides of the bottom of the lifting plate, and a first lower die and a second lower die are fixedly nested on both sides of the top of the worktable, respectively located directly below the first upper die and the second upper die.
[0016] The technical effects and advantages of this utility model are as follows:
[0017] This invention can position the sheet material before and after the first deep drawing and stamping process, thereby preventing misalignment when it moves from the first stamping station to the second stamping station. This allows the subsequent deep drawing and stamping forming mechanism to accurately stamp the sheet material, effectively improving stamping accuracy. Attached Figure Description

Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0027] Figure 1 This is a schematic diagram of the overall structure of a deep drawing and stamping die for automotive sheet metal parts according to one embodiment of the present disclosure.
[0028] Figure 2 This is a schematic diagram of the equipment frame 1 and the deep drawing and stamping mechanism 2 of an automotive sheet metal part deep drawing stamping die according to one embodiment of the present disclosure.
[0029] Figure 3 This is a schematic diagram of the sheet material repositioning mechanism 3 of a deep drawing and stamping die for automotive sheet metal parts according to one embodiment of the present disclosure.
[0030] like Figures 1-3 As shown, the deep drawing and stamping forming die for automotive sheet metal parts disclosed herein may include components such as: equipment frame 1, deep drawing and stamping forming mechanism 2, and sheet material transfer mechanism 3.
[0031] like Figure 2 As shown in this disclosure, the equipment frame 1 includes a workbench 11 and a fixed frame 12, wherein the fixed frame 12 is fixedly installed on the top of the workbench 11, and a support leg 13 is fixedly installed on the bottom of the workbench 11, and a base 14 is fixedly installed on the bottom of the support leg 13.
[0032] like Figure 2As shown, in a preferred embodiment, the deep drawing and stamping forming mechanism 2 includes two driving members 21, wherein the two driving members 21 are respectively fixedly disposed on the top two sides of the fixed frame 12, and a lifting plate 22 is fixedly disposed at the bottom end of the output shaft of the two driving members 21. A first upper die 23 and a second upper die 24 are respectively fixedly disposed on the bottom two sides of the lifting plate 22, and a first lower die 25 and a second lower die 26 are respectively fixedly nested on the top two sides of the worktable 11, which are located directly below the first upper die 23 and the second upper die 24.
[0033] Thus, the two driving components 21 can synchronously drive the lifting plate 22 to move down. When the lifting plate 22 moves down, it drives the first upper die 23 and the second upper die 24 to move down synchronously. As the first upper die 23 and the second upper die 24 move down continuously, the first upper die 23 and the second upper die 24, in cooperation with the first lower die 25 and the second lower die 26 respectively, perform deep drawing and stamping on the sheet material located below them.
[0034] like Figure 3 As shown, in this disclosure, the plate-shaped raw material transposition mechanism 3 includes a rotating shaft 31, which passes through the worktable 11 and is rotatably connected to the worktable 11 through a bearing. The motor 32 is fixedly installed at the bottom of the worktable 11 and is connected to the rotating shaft 31 for transmission. The transposition plate 33 is fixedly sleeved on the outside of the rotating shaft 31 and slides against the top of the worktable 11. Two stamping channels 34 are provided, and the two stamping channels 34 are respectively opened on both sides of the top of the transposition plate 33.
[0035] Three sets of positioning components arranged in a ring are provided on the outer side of any stamping channel 34. Each set of positioning components includes a fixing block 35, which is fixedly installed on the top of the shifting plate 33. The sliding shaft 36 passes through the fixing block 35 and is slidably connected to the fixing block 35. The positioning post 37 is fixedly installed on the inner end of the sliding shaft 36 and has a guide slope on the top. The return spring 38 and the outer ring 39 are both sleeved on the outer side of the sliding shaft 36. The return spring 38 is located between the fixing block 35 and the outer ring 39, and the outer ring 39 is fixedly connected to the sliding shaft 36.
[0036] Therefore, the guide slope at the top of the positioning post 37 is used to guide the sheet material, allowing it to enter the first stamping station between the first upper die 23 and the first lower die 25. At this time, the compressed return spring 38, through the outer ring 39 and the sliding shaft 36, pushes the return spring 38 to press the edge of the sheet material, thus achieving positioning. After the deep drawing and stamping forming mechanism 2 performs the first deep drawing and stamping of the sheet material, the edge of the sheet material contracts inward. Simultaneously, the return spring 38 moves inward through the outer ring 39 and the sliding shaft 36, advancing... With the cooperation of three return springs 38, the sheet material is repositioned. Subsequently, the motor 32 drives the shifting disk 33 to rotate through the rotating shaft 31, so that when the sheet material moves from the first stamping station to the second stamping station, the sheet material cannot move freely because it is positioned. Compared with the prior art, the sheet material can be positioned before and after the first deep drawing and stamping process, thereby avoiding the offset and misalignment when it moves from the first stamping station to the second stamping station. This allows the subsequent deep drawing and stamping forming mechanism 2 to accurately stamp the sheet material, effectively improving the stamping accuracy.
[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.
[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
