Embodiment Construction

[0025] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0026] The present invention provides a method of laying silk to increase the laying stroke of a concave cylindrical surface, and laying silk on a curved surface includes the following steps:

[0027] Step 1, design the trajectory according to the shape of the surface

[0028] Step 2, convert the trajectory into mechanical language, and control the operation of the equipment. In this step, for the curved surface that needs to be laid, the inclined angle is used to press and lay the shape. The curved surfaces include but are not limited to the following types: semi-cylindrical concave curved surfaces, cylindrical surfaces, elliptical cylindrical surfaces, vertica...

Abstract

The invention discloses a silk laying method for enlarging the laying stroke of a concave cylindrical surface, which can effectively change the stroke of the lifting shaft by applying pressure at an inclination angle and expand the processing range of the equipment. The present invention adopts inclination angle pressure laying for semi-cylindrical concave curved surface, cylindrical surface, elliptical cylindrical surface, vertical surface, inclined plane and other curved surfaces, and controls the pressing direction of the pressure roller on the curved surface, and the addition energy of the inclination angle of the laying head Effectively reduce the stroke of the lifting shaft, expand the working margin of the lifting shaft, and increase the processing range of the equipment, so as to realize the silk laying of a larger curved surface within the limited travel range of the lifting shaft. Within the specific processing range of the equipment, the method of applying pressure at an inclination angle can maximize the laying area.

Description

technical field [0001] The invention belongs to the technical field of automatic wire laying and molding, and relates to a wire laying method for increasing the laying stroke of a concave cylindrical surface. Background technique [0002] Due to its high quality, high efficiency and strong adaptability, automatic wire laying technology has been widely used in the automatic forming process of advanced composite components with complex shapes. At present, the automatic wire laying forming technology has become the standard manufacturing technology of large aerospace vehicles, and is widely used in foreign large aircraft manufacturing companies. In view of the sensitivity of this technology in completed fields such as aerospace and foreign technology blockades, my country is still in the initial stage of independent research and development in this area, and only a few research institutes have carried out related research work. [0003] During traditional laying, the pitch axi...
