[0004] The present invention aims to provide a combined laying method and laying equipment for composite materials. 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 wire alone

specific Embodiment approach 1
[0011] Specific implementation mode 1: Combination figure 1 , figure 2 To illustrate this embodiment, this embodiment consists of laying head 1, silk laying head 2, positioning bolt 3, laying belt pressure roller 4, positioning hole 5 and laying belt 6; power on the system and align the initial position , The combined placement head 1 moves down, while the wire placement head 2 feeds the wire, and the placement head 1 feeds the tape. The combined placement head presses the core mold surface placement belt through the pressure roller 4, runs the CNC program, and controls the combined placement The first belt and both sides spreading movement; after the operation is completed, the cutting device of the laying head 1 cuts the laying tape, the cutting device of the laying head 2 cuts the composite material wire 7, and the combined laying head continues to advance for a while to ensure the laying The tape 6 and the wire 7 are pressed to the surface of the mandrel.
specific Embodiment approach 2
[0012] Specific implementation manner two: combination figure 1 , figure 2 , image 3 To illustrate this embodiment, this embodiment consists of laying head 1, silk laying head 2, positioning bolt 3, laying belt pressure roller 4, positioning hole 5 and laying belt 6; in actual production, if the laying belt The width of 6 has changed, which is different from the original. At this time, you only need to adjust the positioning bolt 3 in the combined laying head device, so that the distance between the wire laying heads 2 on both sides is the width of the belt 6; others The composition and operation steps are the same as the first embodiment.
specific Embodiment approach 3
[0013] Specific implementation mode three: combination figure 1 , figure 2 , image 3 To illustrate this embodiment, this embodiment is composed of laying head 1, silk laying head 2, positioning bolt 3, laying belt pressure roller 4, positioning hole 5 and laying belt 6; in actual production, if you only need to use When it comes to the laying function, you only need to use the laying belt 6 function when generating the control code, and the laying head 2 will no longer work during the laying process; the other components and operation steps are the same as the first embodiment.

Abstract
A composite material combined laying method and a special combined laying head pertain to the technical field of composite material molding. The invention is characterized by including the following processes of: 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 or the thread laying is carried out according to the requirements, or the band laying and the thread laying are carried out simultaneously. The special combined laying head is characterized by including 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 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 layingor thread laying.
Description
Technical field [0001] The invention belongs to the technical field of composite material molding. technical background [0002] Composite fiber placement molding technology is a collective term for automatic tow placement molding technology and automatic narrow-band placement molding technology. It is a fully automaticmanufacturing technology developed on the basis of existing winding and automatic placement. The placement head is the core component of the placement equipment, and 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 develop placement equipment. In 1982, they began equipment design, process and material development. Quentin Wood, a mechanical engineer at Boeing, put forward the idea of "AVSD able Sttraind Dispensing Head" (Automated Vari2 able Sttraind Dispensing Head), ...
