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
The invention belongs to technical field of composite material molding.
Technical background
The technology of fiber placement for composite materials forming technique is the general designation of automatic fiber placement beam forming technology and automatic arrowband laying forming technology, is a kind of full-automatic manufacturing technology that grows up on existing winding and automatic placement basis.The lay head is as core component in the laying apparatus, and its structure, performance are determining the quality of the placement performance and the lay product of laying apparatus.
Early start development laying apparatus Boeing company, Cincinnati Milacron company, Hercules company (predecessor of Alliant Techsystems) arranged, nineteen eighty-two begins all work such as equipment design, technology and material development.The mechanical engineer Quentin Wood of Boeing company has proposed " AVSD lay head " (Automated Vari2 able Sttraind Dispensing Head) imagination, has solved basic fibre bundle compacting, cut-out and the problem of heavily sending.Hercules company had developed first principle prototype in 1985, and Cincinnati Milacron company in 1989 designs its first fiber placement system and comes into operation in nineteen ninety; Nineteen ninety-five Ingersoll company develops its first layer.Through the development in surplus 20 years, the fiber placement technical equipment was mature on the whole, and can realize the laying forming of general member, but only depended on shop band lay head to be difficult to realize its lay for the lay of the less core of curvature.
Summary of the invention
The present invention aims to provide a kind of composite combination laying method and laying apparatus, by brand-new mixing lay header structure, make an equipment have the function of lay and shop silk simultaneously concurrently, compare and purchase lay and shop silk equipment simultaneously, it has not only saved equipment cost greatly, and can solve only according to a lay or a shop problem that can not solve.
The lay header structure of shop, shop band both sides silk in the middle of the present invention adopts, centre is the belt spreading machine structure, and both sides are yarn spreading mechanism, respectively two monolateral shop silk heads are fixed on the both sides of belt spreading machine structure by bolt and nut, and the three is interference mutually spatially; Can adjust two distances between the silk head of shop simultaneously, thereby guarantee not gap of lay according to the spacing of the width adjustment bolt of lay band.In reality processing, can select the shop band as required, or the shop silk, or spread band and monolateral shop silk simultaneously, or spread band and bilateral shop silk simultaneously; Aspect lathe operation control, can adopt same motion controller to realize the motion control of lay head and shop silk head simultaneously, define after the sign of each kinematic axis, when writing Machine Tool Control, needs according to reality processing enroll corresponding kinematic axis code, realize interlock control.
This lay header structure can be according to the width implementation structure width adjustment of composite material laying band, thereby the lay band that is fit to various width in addition, can also select only to adopt lay or shop silk according to the needs of technology, realize product manufacturing moulding, increase the flexibility of composite material forming greatly.

Number in the figure title: 1, lay head, 2, a shop silk head, 3, bolt, 4, press roller, 5, locating hole, 6, the lay band, 7, the composite silk.
The specific embodiment
The specific embodiment one: in conjunction with Fig. 1, Fig. 2 present embodiment is described, present embodiment presses roller 4, locating hole 5 and lay band 6 to form by lay head 1, shop silk 2, bolt 3, lay band; Power on to system, aim at initial position, combination laying head 1 moves down, and shop silk 2 wire feed, lay head 1 send band simultaneously, and the combination laying head is pressed by pressing 4 pairs of mandrel surface lay band applications of roller, operation numerical control program, control combination lay head shop band and the silk motion of shop, both sides; After operation finished, the cutter sweep of lay head 1 cut off the lay band, and the shear of shop silk 2 is cut off composite silk 7, and the combination laying head moves on one section and is attached to mandrel surface to guarantee that lay band 6 and silk 7 are pressed.
The specific embodiment two: in conjunction with Fig. 1, Fig. 2, Fig. 3 present embodiment is described, present embodiment presses roller 4, locating hole 5 and lay band 6 to form by lay head 1, shop silk 2, bolt 3, lay band; When actual production, if variation and original different has taken place for the width of lay band 6, at this moment, only need to adjust the bolt 3 in the combination laying head unit, be that the distance between shop, the both sides silk 2 gets final product with 6 width for the shop; Other composition and operating procedure are identical with the specific embodiment one.
The specific embodiment three: in conjunction with Fig. 1, Fig. 2, Fig. 3 present embodiment is described, present embodiment presses roller 4, locating hole 5 and lay band 6 to form by lay head 1, shop silk 2, bolt 3, lay band; When actual production, if only need use the lay function, so only need when generating control routine, only use the function of lay band 6 get final product, just no longer work at lay process middle berth silk 2; Other composition and operating procedure are identical with the specific embodiment one.
The specific embodiment four: in conjunction with Fig. 1, Fig. 2, Fig. 3 present embodiment is described, present embodiment presses roller 4, locating hole 5 and lay band 6 to form by lay head 1, shop silk 2, bolt 3, lay band; When actual production, as if only using a shop silk function, at first need adjust bolt 3, with a shop silk middle distance continuously of 2 modulation on both sides, need when generating control routine, only use the function of shop silk then, lay head 1 is just no longer worked in the lay process; Other composition and operating procedure are identical with the specific embodiment one.
Claims (2)
