[0004] The present invention aims to provide a composite laying head and a combined laying method. Through a new hybrid laying head structure, one piece of equipment can have the functions of laying and silk laying at the same time. Compared with the simultaneous purchase of laying and laying Silk equipment, which not only greatly saves equipment costs, but also solves problems that cannot be solved by laying or laying silk alone

specific Embodiment approach 1
[0012] Specific implementation mode one: combine figure 1 , figure 2 To illustrate this embodiment, this embodiment is composed of a laying head 1, a silk laying head 2, a positioning bolt 3, a laying belt pressure roller 4, a positioning hole 5 and a laying belt 6; power on the system and align it with the initial position , the combination laying head 1 moves down, and at the same time, the wire laying head 2 feeds the wire, and the laying head 1 feeds the belt. The combined laying head presses the laying belt on the surface of the mandrel through the pressure roller 4, and runs the numerical control program to control the combined laying Tape laying at the head and wire laying movement on both sides; after the operation is completed, the cutting device of the laying head 1 cuts the laying tape, and the shearing device of the laying head 2 cuts the composite material filament 7, and the combined laying head continues to move forward for a section to ensure laying The tape ...
specific Embodiment approach 2
[0013] Specific implementation mode two: combination figure 1 , figure 2 , image 3 To illustrate this embodiment, this embodiment is composed of a laying head 1, a silk laying head 2, a positioning bolt 3, a laying belt pressure roller 4, a positioning hole 5 and a laying belt 6; in actual production, if the laying belt The width of 6 has changed, and it is different from the original one. At this time, it is only necessary to adjust the positioning bolt 3 in the combined laying head device, so that the distance between the laying heads 2 on both sides is the width of the tape 6; other The composition and operation steps are the same as those in Embodiment 1.
specific Embodiment approach 3
[0014] Specific implementation mode three: combination figure 1 , figure 2 , image 3 To illustrate this embodiment, this embodiment consists of a laying head 1, a laying head 2, a positioning bolt 3, a laying belt pressure roller 4, a positioning hole 5 and a laying belt 6; in actual production, if you only need to use To the laying function, then only need to use the function of the laying belt 6 when generating the control code, and the silk laying head 2 will no longer work during the laying process; other components and operation steps are the same as the specific embodiment one.

Abstract
The present invention relates to a composite material combined laying head and a combined laying method, belonging to the technical field of composite material molding. The combined laying head is characterized by: a band laying mechanism, two unilateral thread laying heads which are respectively fixed at the two sides of the band laying mechanism by locating bolts and nuts. The three parts are not interfered by one another, and the distance between the two thread laying heads is adjusted by the locating bolts and the nuts, and the distance equals to the width of the band laying. The combined laying method comprises the following steps: compounding the processes of band laying and thread laying, and utilizing a same motion controller to control the motion of the laying head and a thread laying head; and in practical processing, the band laying and the thread laying are carried out simultaneously. The invention causes one piece of equipment to have the functions of both laying and thread laying. Compared with the method of buying laying equipment and thread laying equipment simultaneously, the invention greatly saves the cost of the equipment and solves the problems which can not be solved by single laying or thread laying.
Description
technical field [0001] The invention relates to a composite material combined laying head and a combined laying method, belonging to the technical field of composite material forming. technical background [0002] Composite fiber laying and forming technology is a general term for automatic tow laying and forming technology and automatic narrow tape laying and forming technology. It is a fully automaticmanufacturing technology developed on the basis of existing winding and automatic laying. The placement head is the core component of the placement equipment, its structure and performance determine the placement performance of the placement equipment and the quality of the placement products. [0003] Boeing, Cincinnati Milacron, and Hercules (the predecessor of Alliant Techsystems) were the first to start developing laying equipment. In 1982, they started equipment design, process and material development and other work. Quentin Wood, a mechanical engineer at Boeing, propo...
