Abstract

The invention relates to a pneumatic cutting method of an automobile acoustic part ceiling, and belongs to the technical field of automotive upholstery. The pneumatic cutting method comprises the following steps of firstly setting a pneumatic cutter cutting tool condition, placing the ceiling on a tire film of a tool, locating the ceiling, compacting the ceiling by a frame pressing device, lowering a cutting head device of a cutting machine into a rail groove, starting a pneumatic button, cutting to the end through the cutting head device of the cutting machine according to a running path, taking in a blade after cutting, locking a bolt, loosening the frame pressing device through the pneumatic button, lifting the frame pressing device until the frame pressing device rotates to the original position, pulling a base material on a cutting edge of a product off from a lining, uniformly spraying glue on the lining of the base material removing part of the product, straining the lining to cover the base material, and pasting. As innovation and breakthrough of technology, the pneumatic cutting method provided by the invention has the advantages of simple, compact and reasonable structure, coherent technology movement and high automation degree, input cost of equipment can be lowered, and positioning of products is accurate. According to the pneumatic cutting method, the mechanism is light and handy, the fabricating cost of a product is reduced, an energy source is saved, the product quality is improved, the requirements of clients are met, the cost is reduced, and more economic benefits can be created.

Description

technical field [0001] The invention relates to a pneumatic cutting method for the canopy of an automobile acoustic component, in particular to a pneumatic cutting tool with a cutter, which can cut the unnecessary residual part of the canopy base material cleanly under the action of pneumatic control, and can The fabric is preserved intact and meets the new technology of hemming and assembling, which belongs to the technical field of automotive interior parts. Background technique [0002] With the improvement of people's living standards and aesthetic viewpoints, the requirements for the appearance of automobile interiors are getting higher and higher. In order to meet people's aesthetic requirements, the roof of some high-end models needs to be wrapped around the sunroof and the front and rear edges, in order to cover the appearance defects caused by the leakage of the base material on the cut surface of the product, which will affect the appearance of the whole vehicle. ...
