Abstract
The invention belongs to the technical field of composite material manufacturing and relates to a method for controlling the jointing gap of prepreg cloth in the prepreg cloth paving and pasting process of automatic belt paving equipment. Unidirectional prepreg belts are not allowed to be overlapped during paving and pasting, and according to the technical requirement, the overlapping gap between cloth blocks is 0-2 mm; and while, during practical production, the gap value of paving layers of the unidirectional prepreg belts is not stable and cannot meet the designed technical requirement, and the product quality is seriously influenced. According to the provided method for controlling the jointing gap of unidirectional prepreg belts, the initial paving point of one unidirectional prepreg belt on the paving base level of a mold is set and located on the center line of the unidirectional prepreg belt paving track; after paving and pasting of the last unidirectional prepreg belt are completed, shearing is conducted in the direction perpendicular to the unidirectional prepreg belt, and then paving and pasting of the next unidirectional prepreg belt are conducted; and accordingly, the technical requirement is met, so that normal operation of production is ensured.
Description
Technical field
The invention belongs to manufacture technology of composite material, relate to a kind of control automated tape-laying equipment paving prepreg cloth mistake
The method splicing gap in journey.
Background technology
The paving of prepreg one-way tape does not allow overlap joint, and the overlap joint gap technology requirement between cloth and cloth is
0-2mm, in order to meet this requirement, is generally 1mm ± 1mm by theory setting value.But in actual production, in advance
Leaching material one-way tape laying gap numerical value is unstable, it is impossible to meet the technology requirement of design.Have a strong impact on product
Quality.
Summary of the invention
The technical problem to be solved is to propose a kind of side controlling prepreg one-way tape splicing gap
Method, to meet technical requirement on design, thus ensures that produce is normally carried out.
A kind of method controlling prepreg one-way tape monolayer splicing gap, forms multilamellar for paving in a mold
The product of structure, the process employs following steps:
Step one, by prepreg one-way tape and mould founding mathematical models, the mathematical model of prepreg one-way tape
Including ply stacking-sequence and the laying direction of every layer and gap, the mathematical model of mould includes laying datum level；
Step 2, setting prepreg one-way tape, in the lay starting point laid on datum level of mould, are laid
Initial point is on the centrage of prepreg one-way tape laying track；
Step 3, from lay starting point, determine that the paving track of every prepreg one-way tape is phase Tongfang
To；
Step 4, adjust according to the order of laying and start paving, complete in a upper prepreg one-way tape paving
Tailing edge is perpendicular to the direction of prepreg one-way tape and carries out cutting, then carries out the paving of next prepreg one-way tape
Patch.
The invention has the beneficial effects as follows: present invention determine that a kind of effective paving process, in advance
During leaching material one-way tape paving, splicing seams cannot meet the problem of 0-2mm and improved, thus eliminates paving
Accessory size deviation.
Detailed description of the invention
Enumerate the detailed description of the invention implementing foregoing invention content,
1. the CPD module tool under CATIA environment by product and mould, set up product mathematical model and
The mathematical model of mould, the mathematical model of product includes laying information and ply stacking-sequence, the mathematical model of mould
Including laying datum level, laying datum level and refer to the binding face of mould and product surface, laying information includes often
The laying boundary line of one layer and laying angle 45 ° or 90 °, ply stacking-sequence refers to that product is opened from laying datum level
The stacking sequence of the lay successively begun；
2. set the prepreg one-way tape lay starting point laid on datum level at the mathematical model of mould,
The width of the paving block that this starting point is laid is consistent with the bandwidth of prepreg one-way tape, and lay starting point is in preimpregnation
On the centrage of material one-way tape laying track, and the gap between prepreg one-way tape is set；
3., from laying starting point, determine the paving track of prepreg one-way tape；
4. the order adjusting laying is adjusted to same direction and starts paving；
5. carry out track optimizing, the head end of the initial end of the second layer Yu ground floor is optimized process；
6. carry out laying simulation according to the track after optimizing；
7. the operation that Program transformation becomes coordinate figure input equipment performs system, makes equipment complete assigned operation.
