Method for manufacturing cabin door of passenger car

Abstract

The invention discloses a method for manufacturing a cabin door of a passenger car. The method comprises the following steps of: A) manufacturing a door plank of the cabin door of the passenger car; B) manufacturing a skeleton of the cabin door of the passenger car; C) combining the skeleton and the door plank, namely tearing isolation paper of an adhesive tape from the skeleton off, placing the door plank on a long platform, correspondingly positioning position lines on the skeleton and the door plank, assembling the door plank and the skeleton, and pressing manually to ensure that the periphery of the door plank is bonded with the skeleton; turning the cabin door, tapping the surface of the cabin door manually and uniformly, so that the door plank is bonded with the skeleton, injecting glue at the bonding edge of the skeleton and the cabin door plank by using a glue nozzle, and clamping the skeleton and the door plank by using an S-shaped clamp quickly after glue injection; and D) performing ageing treatment on the cabin door and disassembling the clamp. By the method for manufacturing the cabin door, the surface quality of the cabin door of the passenger car can be improved obviously, the surface is smooth, and the glossiness of paint is also improved obviously.

Description

technical field [0001] The invention relates to a method for manufacturing a cabin door of a passenger car. Background technique [0002] At present, the production of rear hatch doors in my country's passenger car industry can be roughly divided into three categories: stamping structure, glass fiber reinforced plastic structure, and aluminum structure. As a large city bus, if the rear door is larger, if the stamping structure is used, the mold cost is relatively large, and not many manufacturers use it; if the glass fiber reinforced plastic structure is used, the mold cost is relatively reduced, but the deformation after forming is large, and the quality of the arc surface There is no effective guarantee, and rusty water leaks out of the process hole at the lower part of the door, which affects the appearance of the whole vehicle, and some manufacturers are still using it; relatively many manufacturers use aluminum structures, and the production process adopts welding and g...

As a large city bus, if the rear door is larger, if the stamping structure is used, the mold cost is relatively large, and not many manufacturers use it; if the glass fiber reinforced plastic structure is used, the mold cost is relatively reduced, but the deformation after forming is large, and the quality of the arc surface There is no effective guarantee, and rusty water leaks out of the process hole at the lower part of the door, which affects the appearance of the whole vehicle, and some manufacturers are still using it; relatively many manufacturers use aluminum structures, and the production process adopts welding and glue bonding or Riveting and glue bonding solve the phenomenon of rust and water, but the surface quality cannot be effectively guaranteed, especially at the welding and riveting parts. At the same time, cracking and printing will appear after the surface of the riveting part is painted.
