Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive wheel arch outer panel processing technology, specifically an automotive wheel arch outer panel drawing die. Background Technology
[0002] As is well known, wheel arch panels are an indispensable outer covering on a vehicle. Their production materials include steel plates and plastics (glass fiber reinforced plastics, thermoplastic plastics, etc.). During the production process, the materials need to be processed using drawing dies to produce automotive wheel arch panels.
[0003] For wheel arch panels made of plastic, the current wheel arch panel drawing dies sometimes fail to completely cut and separate the edge material after processing. When workers manually pull this edge material off the wheel arch panel, the characteristics of the plastic material and the difficulty in precisely controlling the force and direction during operation easily cause scratches, deformation, and other damage to the edge areas. This damage not only affects the appearance quality of the wheel arch panel but may also alter its structural integrity, reducing its protective performance and stability during vehicle operation. Therefore, its practicality is not ideal, and there is room for improvement. Utility Model Content

[0012] Preferably, the workbench is provided with guide rods around its perimeter, and the upper mold is provided with through holes around its perimeter, which are arranged through the guide rods.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a drawing die for the outer panel of an automobile wheel arch, which has the following advantages:
[0015] This automotive wheel arch outer panel drawing die, when the wheel arch outer panel is processed and formed, drives the cutting device in the upper die groove to move downward by activating the electric push rod, cutting the material at the edge of the wheel arch outer panel, so that the material at the edge is completely separated from the wheel arch outer panel. Therefore, it is not necessary for the staff to manually pull these edge materials off the wheel arch outer panel, avoiding scratches and deformation of the wheel arch outer panel due to the staff's inability to accurately control the force and direction, thus improving its practicality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5 This utility model discloses a drawing die for an automotive wheel arch outer panel, comprising a worktable 1, a lower die 2 disposed in the middle of the worktable 1, on which the material to be processed is placed for subsequent processing. A support plate 3 is disposed on one side of the worktable 1, and a hydraulic cylinder 4 is installed in the middle of the support plate 3. An upper die 5 is disposed below the hydraulic cylinder 4. The hydraulic cylinder 4 extends and drives the upper die 5 to move downward, pressing the material into the lower die 2 for shaping and drawing into the finished wheel arch outer panel. A groove 6 is disposed in the lower part of the upper die 5, and a cutting device 7 is slidably connected thereto, used to cut off the edge material of the wheel arch outer panel, separating it from the drawn wheel arch outer panel. Extension plates 8 are disposed on both sides of the cutting device 7, and height adjustment devices are disposed on the upper part of several extension plates 8, used to drive the cutting device 7 to move up and down within the groove 6, facilitating the cutting of the edge material of the wheel arch outer panel.
[0024] The height adjustment device is a common electric push rod 9. When the electric push rod 9 is activated and extended, it can drive the extension plate 8 and the cutting device 7 to move downward to cut the edge material of the outer plate of the cutting wheel cover. There is a gap between the electric push rod 9 and the side wall of the upper mold 5 to prevent the electric push rod 9 from rubbing against the upper mold 5 when it extends or retracts.
[0025] The upper part of the electric push rod 9 is provided with a fixing plate 10. A first threaded hole is provided on one side of the fixing plate 10, and a bolt 11 is threadedly connected thereto. The upper part of the upper mold 5 is provided with several second threaded holes, which are threadedly connected to the corresponding bolts 11. By screwing the bolts 11 into the first threaded hole of the fixing plate 10 and the second threaded hole of the upper mold 5, the electric push rod 9 can be fixed on the upper mold 5.
[0026] A control box 12 is provided at the rear of the workbench 1 and is electrically connected to the electric push rod 9. It is used to control the operation of the electric push rod 9 so that the electric push rod 9 drives the cutting device 7 to move up and down.
[0027] The upper part of the worktable 1 is provided with a cutting groove 13. The cutting device 7 is matched with the cutting groove 13. The electric push rod 9 drives the cutting device 7 to move upward, cutting the edge material of the outer plate of the cutting wheel cover and entering the cutting groove 13, so that it will not collide with the worktable 1 and be damaged.
[0028] Guide rods 14 are provided around the workbench 1, and through holes are provided around the upper mold 5, which are connected to the guide rods 14. When the hydraulic cylinder 4 drives the upper mold 5 to move downward, the guide rods 14 and the through holes of the upper mold 5 move relative to each other, which guides the movement of the upper mold 5.
[0029] In summary, when using this automotive wheel arch outer panel drawing die, the operator places the material to be processed onto the lower die 2, then activates the hydraulic cylinder 4, which extends and moves the upper die 5 downward. The lower part of the upper die 5 presses against the upper part of the material and extends into the lower die 2 to shape the material. After shaping, the electric push rod 9 is activated, extending and moving the extension plate 8 and the cutting device 7 downward within the groove 6 of the upper die 5 to cut off the edge material that will become the wheel arch outer panel. The lower part of the cutting device 7 enters the cutting groove 13 of the lower die 2. Then, the electric push rod 9 retracts, moving the cutting device 7 into the groove 6. After that, the hydraulic cylinder 4 is activated, retracting and moving the upper die 5 upward. Finally, the operator removes the wheel arch outer panel and the cut edge material.
