Description

Technical Field

[0001] This invention belongs to the field of metal additive manufacturing, and specifically relates to a composite material arc additive manufacturing device based on adjustable rocker arm lateral reciprocating wire laying. Background Technology

[0002] Conventional electric arc additive manufacturing (EAC) technology uses a high-temperature electric arc generated between a deposited filament and the deposited part as a heat source, simultaneously melting the filament and heating the deposited part. This allows for rapid part manufacturing through layer-by-layer material deposition. This technology offers advantages such as low cost, high deposition rate, high material utilization, and high density of the deposited part. However, existing EAC equipment, limited by the strength of the deposited filament material, still cannot meet the material properties of the deposited parts required for harsh operating conditions. This restricts the widespread adoption and application of EAC technology. Furthermore, the development of novel high-performance deposited filaments requires significant time and cost. Therefore, to improve the material properties of EAC deposited parts, reinforcing fibers must be added to the existing deposition process to form a composite material. Traditional reinforcing fiber placement devices lack precise control over the placement and positioning of the reinforcing fibers, easily leading to fiber misalignment and stacking. Simultaneously, the electric arc can easily burn the reinforcing fibers, affecting the final composite material properties of the deposited part.

[0003] The present invention discloses a composite material arc additive manufacturing device based on an adjustable rocker arm lateral reciprocating filament arrangement. The adjustable rocker arm lateral reciprocating filament arrangement mechanism enables the reinforcing fiber filaments to be reciprocated and arranged in the deposition part as needed. At the same time, the swing amplitude and swing frequency of the filament oscillation guide rod can be dynamically adjusted according to the shape changes and performance requirements of the deposition part, so as to achieve the on-demand or uniform arrangement of the reinforcing fiber filaments and improve the material properties of the deposition part.

The outer right side wall of the yarn tensioning and storage reel contacts the shoulder of the central shaft of the yarn tensioning and storage reel, for axial positioning of the right end of the yarn tensioning and storage reel. The yarn tensioning and storage reel is used to wind and store the reinforcing fiber yarn. After the reinforcing fiber yarn is led out through the yarn tensioning and storage reel, it enters the yarn inlet of the yarn swing adjustment guide rod for subsequent output of the reinforcing fiber yarn. This product is used for high-strength fiber filament operations. The filament tensioning damping block base is mounted on the inner side of the left support frame of the filament tensioning base.

Continuous clamping force; when the reinforcing fiber moves along the discharge direction, the reinforcing fiber pushes the top V-shaped notch of the upper and lower clamping plates of the fabric filament clamping slightly open, and slides out smoothly after overcoming part of the clamping force; when the reinforcing fiber moves in the opposite direction, the upper and lower clamping plates of the fabric filament clamping continue to tighten under the action of clamping force, preventing the reinforcing fiber from moving back, forming a one-way self-locking effect of the reinforcing fiber during fabric feeding.

[0011] Preferably, in the composite material arc additive manufacturing process, the wire feeder continuously feeds welding wire into the welding torch through the wire feed tube.

The heating effect of the electric arc causes a molten pool to form on the surface of the deposited part. Simultaneously, the adjustable rocker arm lateral reciprocating wire feeding mechanism operates under the drive of the wire feeding amplitude adjustment drive motor and the wire feeding frequency adjustment drive motor. The wire feeding amplitude adjustment drive motor drives the wire feeding arm through the wire feeding amplitude adjustment rigid coupling. The rotation of the fabric sway adjustment screw causes the fabric sway adjustment slider to move axially along the fabric sway adjustment screw under the constraint of the fabric sway adjustment guide rail, thereby driving the position of the fabric sway adjustment guide rod to change, thus adjusting the transverse fabric width of the reinforcing fiber; the fabric sway frequency adjustment drive motor drives the fabric sway frequency adjustment crank to rotate, causing the fabric sway adjustment guide rod to oscillate periodically, thereby enabling the reinforcing fiber to be reciprocated within the molten pool area; by changing the rotation speed of the fabric sway frequency adjustment drive motor, the oscillation frequency of the fabric sway adjustment guide rod is adjusted, thereby adjusting the transverse fabric density of the reinforcing fiber; the welding wire tip melts under arc heating to form molten droplets and transitions into the molten pool, covering and encapsulating the reinforcing fiber, and solidifying to form a composite material; the support beam pitch angle adjustment ring adjusts the angle between the upper support beam and the lower support beam, thereby adjusting the height and angle between the fabric sway adjustment guide rod and the deposition piece; the fabric tensioning structure uses the fabric tensioning damping spring to tension the fabric. The damping block is pressed against the outer left side of the fabric tensioning storage tray, applying tension force to the fabric tensioning storage tray during the fabric feeding process to prevent excessive fabric feeding due to inertia. The fabric clamping structure supports the upper and lower clamping plates of the fabric clamping structure through the base of the fabric clamping structure, and applies clamping force to the reinforcing fiber under the action of the fabric clamping hook spring, so that the reinforcing fiber can pass smoothly in the discharge direction, but is blocked in the reverse direction, realizing the unidirectional discharge of the reinforcing fiber.
