Description
Technical field
The present invention relates to composite material automatic placement molding technical fields more particularly to a kind of for double with rib revolving body
Pressure roller spreads automatically and twines molding machine.
Background technique
Mainstream manufacturing technology of the composite material automatic placement technology as high-performance composite materials complex large-scale component,
As the standard configuration manufacturing technology of large aerospace spacecraft, it is widely used in the automation paving of the large-scale components such as airframe, wing
Put molding.
Currently, automatic placement technology is also used for the molding of some composite material spars containing corner angle or special shaped gyrorotor,
The curvature of corner angle is larger, and there are more problems in crossing rib laying compacting process.In addition, since knuckle is relatively thin, cannot bear compared with
Big compaction force.
To sum up, lack the paving side's device for being suitable for meeting material containing corner angle in the prior art, avoid using common laying
The problem of when device, paving side is inefficient, and edges and corners cannot bear larger pressure.
Summary of the invention
The present invention provides a kind of spread automatically for the twin pressure roller with rib revolving body and twines molding machine, for composite element
Corner angle shaping characteristic and requirement realize that the automatic placement of edges and corners prepreg strap is compacted by spreading the mode of twining using twin pressure roller
Type.
In order to achieve the above objectives, the present invention adopts the following technical scheme:
A kind of spread automatically for the twin pressure roller with rib revolving body twines molding machine, comprising:
Main pressure roller, auxiliary pressure roller, main pressure roller cylinder, auxiliary pressure roller cylinder, stationary plane, auxiliary pressure roller linkage board, main pressure roller linkage board.
The central axis both ends of main pressure roller connect one group of main pressure roller linkage board, and the central axis both ends of auxiliary pressure roller connect one group of auxiliary pressure
Roller linkage board.Main pressure roller linkage board is also connected with main pressure roller cylinder and auxiliary pressure roller cylinder, the piston extension end of main pressure roller cylinder and master
The connection of pressure roller linkage board, the tail portion of main pressure roller cylinder is connected with stationary plane.
Auxiliary pressure roller linkage board is also connected with main pressure roller linkage board and auxiliary pressure roller cylinder, the piston extension end of auxiliary pressure roller cylinder and auxiliary
The connection of pressure roller linkage board, when the piston of auxiliary pressure roller cylinder stretches out, auxiliary pressure roller is rotated by shaft of main pressure roller.
Further, main pressure roller cylinder and auxiliary pressure roller cylinder are single-acting cylinder.
In the present invention, main pressure roller cylinder and auxiliary pressure roller cylinder provide compaction force respectively for main pressure roller and auxiliary pressure roller.Wherein, main
Pressure roller realizes compaction force using linear-movable manner, and the action direction of compaction force, action direction are adjusted using active control mode
It is determined according to mold surface shape by digital control system.Auxiliary pressure roller applies compaction force using swing mode, presses based on swing shaft
It is moved with the movement of main pressure roller the position of roll axis, auxiliary pressure roller cylinder supports point.
Prepreg strap is between main pressure roller and auxiliary pressure roller and mold, in the phase that main pressure roller and auxiliary pressure roller are turned round with mold
To in motion process, prepreg strap is compacted in die surface.
In the movement of non-corner region, main pressure roller and auxiliary pressure roller are bonded always and are compacted in die surface；When main pressure roller is transported
When dynamic corner region edge, main pressure roller cylinder controls main pressure roller break away from moulds, auxiliary pressure roller fitting and compaction tool surface；When auxiliary
When pressure roller moves to knuckle edge, by prepreg Fabric tape winding hanging between main pressure roller and auxiliary pressure roller to mold corner angle position,
Main pressure roller contacts die surface but is not compacted, and auxiliary pressure roller fitting die surface is servo-actuated and prepreg strap is compacted in mold table
Face；After auxiliary pressure roller leaves corner region completely, controls main pressure roller and prepreg is compacted in die surface, auxiliary pressure roller is in mould
It is servo-actuated to have surface, and prepreg strap is repeated to be compacted.Main pressure roller is compacted point position in die surface and is arranged according to specific mold.
The beneficial effects of the present invention are:
The debulking methods that the present invention uses main pressure roller and auxiliary pressure roller to match, in non-corner region based on main pressure roller, auxiliary pressure roller
Auxiliary compacting；Biggish compaction force cannot be born due to the special construction of corner angle in corner region, so main pressure roller is hanging, it is auxiliary
Pressure roller works independently, and paving side is high-efficient, so as to shorten the laying forming time of revolving body corner region, improves entire revolving body
Automatic placement molding efficiency.
