[0004] However, when stamping auto parts using the above method, the operator needs to first place the sheet metal on the lower die, then start the press to press down the upper die to complete the stamping process. Finally, the press rises and resets, and the operator takes out the sheet metal and stamps the next part. During this stamping process, the operator can only wait for the press to rise and reset before placing the next part for stamping, resulting in low work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a stamping forming device for auto parts, which solves the problem that when stamping auto parts, the operator needs to first place the sheet metal on the lower die body, then start the press to make the upper die body press down to complete the stamping process, and finally the press rises and resets, and the operator takes out the sheet metal and stamps the next part. In this stamping process, the operator can only wait for the press to rise and reset before placing the next part for stamping, resulting in low work efficiency.

[0006] To achieve the above objectives, this utility model provides a stamping forming device for automotive parts, including a worktable and a forming assembly. The forming assembly includes a stamping rod, a rotating plate, a mounting plate, a fixed shaft, and two workstation structures. The mounting plate is fixedly installed on the upper end of the worktable. One end of the fixed shaft is fixedly connected to the mounting plate. The rotating plate is rotatably connected to the fixed shaft, and the fixed shaft passes through the rotating plate. The stamping rod is movably disposed above the rotating plate. The two workstation structures are respectively disposed below both ends of the rotating plate. Each workstation structure includes a guide sleeve, a stamping column, an upper die body, a lower die body, a connecting block, and an elastic element. The guide sleeve is disposed below the rotating plate. The stamping column is slidably disposed inside the guide sleeve. The connecting block is fixedly connected to the stamping column and is located inside the guide sleeve. The elastic element is located below the connecting block. The upper die body is fixedly installed at the bottom of the stamping column. The lower die body is fixedly installed on the upper end of the worktable and is located below the upper die body.

[0011] This utility model discloses a stamping forming device for automotive parts. When stamping automotive parts is required, two automotive parts are placed in two lower die bodies respectively. The stamping rod moves downward, driving the rotating plate to rotate. One end of the rotating plate rotates downward and presses the stamping column below it downward, causing the stamping column to move downward and bring the upper die body into contact with the lower die body, thereby stamping the automotive parts in the lower die body. Subsequently, the stamping rod moves upward, driving the rotating plate to rotate back. Since the stamping column at this end is no longer... Supported by the rotating plate, the stamping column is reset under the action of the elastic element, causing the upper die body at this end to separate from the lower die body. This facilitates the removal of the formed auto parts and the placement of new auto parts requiring stamping. As the rotating plate rotates, the other end of the plate gradually rotates downwards, causing the stamping column at this end to descend. This brings the upper die body at this end into contact with the lower die body to stamp the auto parts, thus enabling the sequential stamping of auto parts in the two lower die bodies. After one station structure finishes stamping, the other station structure begins stamping the auto parts. At this time, the stamped auto parts in the lower die body can be removed and replaced with new auto parts requiring stamping, thus continuously stamping the auto parts and improving work efficiency.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a stamping forming device for automotive parts according to this utility model. Figure 2 This is a structural cross-sectional view of a stamping forming device for automotive parts according to this utility model. Figure 3 This is a cross-sectional view of the structure of an auto parts stamping and forming device according to this utility model from another direction.

[0019] This utility model provides a stamping forming device for auto parts, including a worktable 100 and a forming assembly. The forming assembly includes a stamping rod 210, a rotating plate 220, a mounting plate 230, a fixed shaft 240, two workstation structures, and a connecting seat 340. The workstation structures include a guide sleeve 250, a stamping column 260, an upper die body 270, a lower die body 280, a connecting block 290, an elastic element, and an L-shaped mounting bracket 310. The elastic element includes a spring 320 and a rubber pad 330.

[0020] In this specific embodiment, the mounting plate 230 is fixedly mounted on the upper end of the workbench 100, one end of the fixed shaft 240 is fixedly connected to the mounting plate 230, the rotating plate 220 is rotatably connected to the fixed shaft 240, the fixed shaft 240 passes through the rotating plate 220, the stamping rod 210 is movably disposed above the rotating plate 220, two workstation structures are respectively disposed below both ends of the rotating plate 220, the guide sleeve 250 is disposed below the rotating plate 220, the stamping column 260 is slidably disposed inside the guide sleeve 250, the connecting block 290 is fixedly connected to the stamping column 260, the connecting block 290 is located inside the guide sleeve 250, the elastic element is located below the connecting block 290, the upper die body 270 is fixedly mounted on the bottom of the stamping column 260, the lower die body 280 is fixedly mounted on the upper end of the workbench 100, and the lower die body 280 is located below the upper die body 270. The rotating plate 220 is rotatable relative to the fixed shaft 240. The stamping rod 210 drives the rotating plate 220 to rotate. The two workstation structures are spaced apart below both ends of the rotating plate 220. The stamping column 260 can slide up and down inside the guide sleeve 250, which guides the movement of the stamping column 260. The elastic element is elastic and supports the connecting block 290 upward, so that there is a certain distance between the upper die body 270 and the lower die body 280 when no external force is applied, so that the worker can place the auto parts to be stamped in the lower die body 280. The stamping rod 210 can be driven by a hydraulic cylinder or other driving device to move up and down. When stamping automotive parts is required, two automotive parts are placed in the two lower die bodies 280 respectively. The stamping rod 210 moves downward, causing the rotating plate 220 to rotate. The downward rotating end of the rotating plate 220 presses the stamping column 260 below it downward, causing the stamping column 260 to move downward and bring the upper die body 270 into contact with the lower die body 280, thereby stamping the automotive parts in the lower die body 280. Subsequently, the stamping rod 210 moves upward, causing the rotating plate 220 to rotate back. Since the stamping column 260 at this end is no longer subjected to the rotation plate 270, the stamping rod 210 moves upward, causing the rotating plate 220 to rotate back. With the support of 20, the stamping column 260 is reset under the action of the elastic element, so that the upper die body 270 at this end separates from the lower die body 280, so as to remove the formed auto parts and put in a new auto parts that need to be stamped. When the rotating plate 220 rotates, the other end of the rotating plate 220 gradually rotates to the bottom, thereby driving the stamping column 260 at this end to move downward, so that the upper die body 270 at this end contacts the lower die body 280 to stamp the auto parts, thereby realizing the stamping of the auto parts in the two lower die bodies 280 in sequence.After one of the workstation structures completes the stamping process, the other workstation structure begins stamping the auto parts. At this time, the auto parts in the lower die 280 after stamping can be removed and replaced with new auto parts that need to be stamped, thus continuously stamping the auto parts and improving work efficiency. This solves the problem that when stamping auto parts, the operator needs to place the sheet metal on the lower die 280, then start the press to make the upper die 270 press down to complete the stamping process, and finally the press rises and resets, and the operator removes the sheet metal and stamps the next part. In this stamping process, the operator can only wait for the press to rise and reset before placing the next part for stamping, resulting in low work efficiency.

[0021] Furthermore, one end of the L-shaped mounting bracket 310 is fixedly connected to the worktable 100, and the other end of the L-shaped mounting bracket 310 is fixedly connected to the outer side of the guide sleeve 250. The L-shaped mounting bracket 310 is used to mount the guide sleeve 250 to fix the guide sleeve 250.

[0022] Specifically, the rubber pad 330 is fixedly connected to the guide sleeve 250, and the rubber pad 330 is located inside the guide sleeve 250 and below the connecting block 290. The two ends of the spring 320 are fixedly connected to the connecting block 290 and the guide sleeve 250, respectively. During the downward movement of the stamping column 260, the spring 320 is compressed, generating a restoring force. Therefore, when the rotating plate 220 no longer supports the stamping column 260, the stamping column 260 will move upward and reset under the action of the spring 320, thereby causing the upper mold body 270 to separate from the lower mold body 280.

[0023] The connecting seat 340 is slidably connected to the rotating plate 220, and the connecting seat 340 is located above the rotating plate 220. The bottom of the stamping rod 210 is rotatably connected to the connecting seat 340. A movable support 341 is provided at the bottom of the connecting seat 340. The upper end of the rotating plate 220 has a groove 221 adapted to the movable support 341, and the movable support 341 is located inside the groove 221. The connecting seat 340 connects the rotating plate 220 and the stamping rod 210. The movable support 341 at the bottom of the connecting seat 340 can slide inside the groove 221, and the bottom of the stamping rod 210 can rotate relative to the connecting seat 340.

[0024] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
