Description
Technical field
The present invention relates to control of two-dimensional braided technology, specifically a kind of T-shaped prefabricated component integrally covers volume method and apparatus.
Background technology
Control of two-dimensional braided is with a long history, in 18 th Century Germans and French can manufacture control of two-dimensional braided machine.Control of two-dimensional braided machine one
As be used to produce rope, band, the fabric such as pipe.The moulding process of control of two-dimensional braided machine relative maturity at present is straight in general etc.
Footpath pipe can reach relevant art requirement using common two-dimentional circular knitting machine.With the development of composite, two dimension is compiled
Knit technology and the effect to become more and more important is played in the development of composite.Substantial amounts of polymer matrix composites have used two-dimentional volume
Technology is knitted, it has following main feature：1. the mechanization degree of control of two-dimensional braided is higher, production efficiency is high；And it is adapted to two dimension to compile
The moulding process species of Woven composite also compares more.2. the designability of control of two-dimensional braided is stronger, it is straight that braid angle, mandrel can be changed
Footpath and section etc. change the structure of prefabricated component.But the conventional sleeve of control of two-dimensional braided compiles method and has complicated shape and one for manufacture
The prefabricated component for determining thickness is relatively difficult.Presently mainly complicated shape complicated shape and certain thickness pre- is manufactured with 3 D weaving
Product, but 3 D weaving automaticity is low, braiding is difficult, low production efficiency.
The content of the invention
For the technology for existing control of two-dimensional braided, the technical problem that the present invention intends to solve is to provide a kind of T-shaped threeway
The set of control of two-dimensional braided prefabricated component weaves into type method and apparatus.This method can not only realize cylindrical cross-section or other cross sectional shapes
T-shaped threeway, the overall set of T-shaped four-way or T-shaped five prefabricated component such as logical compiles., can be with and yarn is not broken in prefabricated component
Ensure the overall integrity of preform structure.
The technical scheme that the present invention solves methods described technical problem is to design a kind of set of T-type two-dimensional woven preform
Volume method, equipment include conventional control of two-dimensional braided machine, mechanical commutation draft arm and forming ring, there is drawing-off regulation dress on mechanical arm
Put.
The drawing-off regulation of core is realized by the mechanical arm in front of prefabricated component forming direction, passes through programming
It can make mechanical arm that direction set in advance and speed are installed and drawing-off is carried out to core.
A kind of set of T-type two-dimensional woven tubular prefabricated component compiles method, comprises the following steps：
The first step：According to the performance requirement of product, suitable yarn is selected.
Second step：Measure the broadening of yarn tow, for coverage rate needed for reaching and surface density, according to the number of spindles of yarn with
And fabric construction parameters, the core diameter of design.
3rd step：According to required product, T-shaped composite core formwork is formed with two tubular core molds.
4th step：With above-mentioned core in braiding woven preform.
5th step：After fabric reaches the required number of plies, prefabricated component is removed, two cores are separated, taking out core is
It can obtain required T-shaped prefabricated component.
Compared with prior art, forming method of the invention and device can control core with specific by mechanical arm
Direction and speed motion, prevent yarn to core on yarn in the presence of forming ring along forming ring radial outward expansion
Motion, which is formed, to be hindered.The present invention has following technological merit：(1) forming ring is added on ordinary two dimensional braider, beneficial to control
The motion of coremaking mould.(2) carry out reciprocal set by drawing-off core to compile, obtain the prefabricated component of required thickness, and the yarn in prefabricated component
Line splits, so the globality of prefabricated component is preferable without fracture.(3) compared to three-dimensional weaving method, technique is simple, easy making process, raw
It is low to produce cost.

Embodiment
The present invention is further described with reference to example and accompanying drawing.
The set for the T-shaped threeway control of two-dimensional braided prefabricated component that the present invention designs compiles method, after product demand selection yarn
Carry out corresponding technology Calculation, from wider tow yarn when (yarn linear density selected here is consistent), in other conditions
In the case of consistent, same equipment can weave larger sized prefabricated component.
Technology Calculation：Here T-shaped prefabricated component is tubulose (figure), and the diameters of two cylindric cores is all mutually R, yarn 3
Broadening be w, line density t, braid angle θ, the number of spindle unit of braider knitting yarn is m, and axle yarn is n, is generally woven
The quantity of arbor yarn is the half of knitting yarn, then in theory and coverage rate as big as possible in core preferably when core diameter
For：
If product requirement, using surface density ρ as basic principle, core is a diameter of：
Then the flower byte wide f of fabric construction is：
Then the stitch length h of fabric construction is：
Carry out weaving preceding preparation, after being ready to complete, start to weave by the technological parameter calculated.
The A ends (such as Fig. 3) that mechanical arm 1 first starts drawing-off core 6 take up one's knitting, and the direction of arrow is the motion side of core 6
To, when being woven into D ends, mechanical arm 1 adjusts the direction of core 6 and starts drawing-off D ends (such as Fig. 4), when being woven into B ends, machinery
Arm 1 adjusts the direction of core 6 and starts drawing-off B ends (such as Fig. 5)；When being woven into D ends again, mechanical arm 1 adjusts the direction of core 6 and opened
Beginning drawing-off A ends (such as Fig. 6), when being woven into C-terminal, mechanical arm 1 adjusts the direction of core 6 and starts drawing-off C-terminal (such as Fig. 7), works as volume
When knitting A ends, the once set for now completing prefabricated component is compiled, and set, which is organized on core, every time forms two-layer fabrics.If necessary to more
The prefabricated component of more numbers of plies, repeat above step.
