A composite additive manufacturing equipment for continuous fiber thermoplastic material structural parts

Abstract

The invention provides equipment for manufacturing a continuous fiber thermoplastic material structural component composite additional material. The equipment comprises a worktable, a Z axis motion unit, a printing platform, an XY axis motion unit, a thermoplastic material extrusion mechanism and a continuous fiber feeding mechanism, wherein the Z axis motion unit is arranged on the worktable; theprinting platform is arranged on a power output end of the Z axis motion unit; the XY axis motion unit is arranged on the worktable; the thermoplastic material extrusion mechanism and the continuousfiber feeding mechanism are arranged at the power output end of the XY motion unit and positioned above the printing platform; the printing platform comprises a mounting rack, a turning mechanism, a rotating mechanism and a molding support plate; the mounting rack is connected with the power output end of the Z axis motion unit; the turning mechanism is arranged on the mounting rack; the rotatingmechanism is arranged on the turning mechanism, and the rotating shaft is perpendicular to the turning shaft; the molding support plate is arranged on the rotating mechanism. According to the equipment disclosed by the invention, the mechanical property of the structural component manufactured from the thermoplastic additional material is greatly improved, and the problem that the traditional carbon fiber composite structural component is complicated in manufacturing process and long in production cycle and often needs molds and difficultly realizes manufacturing of complicated structures canbe solved.

Description

technical field

[0001] The invention relates to the technical field of continuous fiber composite material manufacturing, in particular to a continuous fiber thermoplastic material structural component composite additive manufacturing equipment. Background technique

[0002] In the past few decades, academia and industry have continuously innovated and developed a variety of additive manufacturing technologies. Among them, thermoplastic material fused deposition modeling technology has become one of the most widely used additive manufacturing technologies because of its low cost and easy operation. However, thermoplastic material fused deposition molding structural parts have obvious shortcomings in terms of mechanical properties. Most printed structural parts are still in the "similar" stage, and the lack of strength greatly limits their direct application in the terminal market, especially for high mechanical strength requirements. field.
