Description

Technical Field

[0001] The invention relates to three-dimensional braiding of composite materials, and in particular to a three-dimensional braided radial yarn implantation device and implantation method. Background Art

[0002] Preforms with three-dimensional woven structures are resistant to impact, internal corrosion, fatigue, and cracking, and are widely used in the aerospace field. In recent years, with the development of aerospace research in my country, the demand for three-dimensional woven preforms has gradually increased. Traditional three-dimensional weaving equipment has a low degree of mechanization and slow weaving speed. The insertion of radial yarns is further limited by factors such as the weaving space and yarn tension, and can only be done manually, which affects weaving efficiency and cannot guarantee the consistency of preform quality. Currently, there is no effective mechanized method for inserting radial yarns into three-dimensional weaving. Summary of the Invention

[0003] Purpose of the invention: In view of the above shortcomings, the present invention provides an efficient, accurate and automated three-dimensional braided radial yarn implantation device.

The inner ring gear is engaged with the teeth of the inner ring guide rail. The inner ring roller is in contact with both sides of the inner ring guide rail. The inner ring drive motor drives the inner ring gear to rotate, driving the inner ring slider to move along the inner ring guide rail. The yarn feeding linear guide rail is fixedly set on the inner ring slider.

[0014] Furthermore, several core molds are fixed above the outer annular guide rail and the inner annular guide rail, one end of the yarn is fixed on the core mold, and the other end passes through the annular area between the outer annular guide rail and the inner annular guide rail. All yarns are arranged in multiple rows in a circular direction, and the starting end of the radial yarn is fixed on the core mold.

[0040] like Figure 1 The figure shows the initial state of the implantation device. At this time, the yarn feeding device: the wire diverter plate driving cylinder 106-1 and the yarn feeding driving cylinder 106-2 are in the retracted state, the wire diverter plate rotating cylinder 109 is in the 0° state, the wire diverter plate 111 is facing upward in thickness direction, the limit plate driving motor 117 is in the 0° state, and the limit plate 118 is inserted into the limit bracket 119; the yarn splicing device: the support plate driving cylinder is in the extended state; the outer annular guide rail assembly 101 in the yarn feeding device 1 and the inner annular guide rail assembly 201 in the yarn splicing device 2 are adjusted to align the yarn feeding linear guide rail 113 with the yarn splicing linear guide rail 207 to ensure that they can be docked.

[0041] Figure 2 The figure shows the state when the yarn-carrying self-propelled moving trolley 3 moves from the yarn-feeding linear guide rail 113 to the yarn-receiving linear guide rail 207;

[0042] The specific process includes the following steps:

[0043] (1) The yarn-carrying self-propelled moving trolley is located on the yarn-feeding linear guide rail, and the radial yarn is wound on the yarn bobbin of the yarn-carrying self-propelled moving trolley;

[0044] (2) The thread plate driving cylinder 106-1 drives the thread plate fixing seat 104 to move, so that the thread plate 111 is inserted into the gap formed by the adjacent rows of yarns. The thread plate rotating cylinder 109 drives the thread plate 111 to rotate 90 degrees. The thread plate 111 expands the gap between the adjacent rows of yarns to the thread plate width;

[0045] (3) The yarn feeding drive cylinder 106-2 drives the yarn feeding guide rail mounting seat 112 to move, so that the yarn feeding linear guide rail 113 is docked with the yarn receiving linear guide rail 207. At this time, the limit plate 118 is inserted into the limit bracket 119 to prevent the yarn carrying self-propelled moving trolley from falling off as the yarn feeding linear guide rail 113 moves;

[0046] (4) The support plate driving cylinder 205 drives the yarn feeding guide rail support plate 203 to move, so that the yarn feeding guide rail support plate 203 is supported under the yarn feeding linear guide rail 113, thereby preventing the yarn feeding linear guide rail 113 from sagging due to the overhanging length being too long and not being at the same height as the yarn receiving linear guide rail 207, resulting in the yarn carrying self-propelled motion trolley being unable to pass;

[0047] (5) The limit plate driving motor 117 rotates 90° to lift the limit plate 118;

[0048] (6) The yarn-carrying self-propelled moving trolley is driven by a motor to move from the yarn-feeding linear guide rail 113 to the yarn-receiving linear guide rail 207, and the radially implanted yarn is collected and released as it moves, maintaining a constant tension;

[0050] (8) The outer ring drive motor 101-4 drives the outer ring gear 101-5 to rotate, and drives the outer ring roller 101-3 to move around the outer ring guide rail 101-1, so that the outer ring slider 101-2 rotates to the middle of the gap between the next yarn rows. The angle α that the outer ring slider needs to rotate can be determined according to the number of yarn rows; at the same time, the inner ring drive motor 201-4 drives the inner ring gear 201-5 to rotate, and drives the inner ring roller 201-3 to move around the inner ring guide rail 201-1, so that the inner ring slider 201-2 rotates in the same direction by the same angle α;

[0051] (9) The thread plate driving cylinder 106-1 drives the thread plate fixing seat 104 to move, so that the thread plate 111 is inserted into the gap formed by the adjacent rows of yarns. The thread plate rotating cylinder 109 drives the thread plate 111 to rotate 90 degrees. The thread plate 111 expands the gap between the adjacent rows of yarns to increase the width of the thread plate.

[0052] (10) The yarn feeding drive cylinder 106-2 drives the yarn feeding guide rail mounting seat 112 to move, so that the yarn feeding linear guide rail 113 is docked with the yarn receiving linear guide rail 207. At this time, the limit plate 118 is still in the raised state;

[0053] (11) The support plate driving cylinder 205 drives the yarn feeding guide rail support plate 203 to move, so that the yarn feeding guide rail support plate 203 is supported under the yarn feeding linear guide rail 113, thereby preventing the yarn feeding linear guide rail 113 from sagging due to the overhanging length being too long and not being at the same height as the yarn receiving linear guide rail 207, resulting in the yarn carrying self-propelled moving trolley 3 being unable to pass;

[0054] (12) The yarn-carrying self-propelled trolley is driven by a motor to move from the yarn receiving linear guide rail 207 to the yarn feeding linear guide rail 113, and then moves to the top of the outer ring slider 101-2. The radially implanted yarn is collected and released as it moves, maintaining a constant tension.

[0055] (13) The limit plate driving motor 117 rotates 90° so that the limit plate 118 is inserted into the limit bracket 119;

[0056] (14) The yarn feeding drive cylinder 106-2 drives the yarn feeding guide rail mounting seat 112 to move and return to the initial position, the thread plate rotating cylinder 109 is reset, and the thread plate driving cylinder 106-1 drives the thread plate fixing seat 104 to move and return to the initial position; the support plate driving cylinder 205 is reset;

[0057] (15) Repeat steps (2) to (14) until the implantation of a full circle of radial yarn is completed. Figure 6 The figure shows a cross-sectional view of the radial yarn after it has been implanted into a full circle.
