Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically to a spraying device for automotive body hardware. Background Technology

[0002] Automotive hardware typically refers to metal parts manufactured using stamping processes, primarily used in automobile production. These parts are shaped by applying pressure to metal using molds and are widely used in categories such as body panels, decorative parts, and fasteners. Painting is an indispensable step in the production of automotive hardware.

[0003] Chinese patent CN222057767U discloses a hardware flipping structure for a hardware spraying device, including a spraying box. The inner wall of the spraying box is rotatably connected to a connecting pipe, and the outer wall of the connecting pipe is fixedly connected to a frame. The outer wall of the connecting pipe is rotatably connected to a turntable. The device rotates the turntable to make the arc groove on the turntable press against the clamping plates, so that the clamping plates come together and separate. It can fix hardware parts of different sizes without the need to use different clamps for fixing, which improves the hardware processing to a certain extent. However, existing spraying devices directly clamp and limit the hardware parts inside the spraying box using clamps. Since the lengths of the hardware parts vary, and only one spray gun is set up in a fixed position, if the hardware parts are long, simply rotating the hardware parts can easily cause uneven spraying or areas that are not sprayed, reducing the spraying effect and affecting the spraying quality. This utility model designs a spraying device for automotive body hardware parts to solve the above problems. Utility Model Content
