2results about How to "Stable wire feeding" patented technology

The application belongs to the technical field of additive manufacturing, and particularly relates to a metal 3D printing fine wire feeding device and an additive manufacturing equipment comprising the same. The fine wire feeding device comprises a shell assembly, a metal wire guiding assembly and a metal wire driving assembly. The shell assembly surrounds the metal wire driving assembly. The metal wire guiding assembly is installed in the shell assembly along the longitudinal direction. The metal wire penetrates through the metal wire guiding assembly and is fed by the metal wire driving assembly. The metal wire driving assembly comprises a driving wheel assembly, a driven wheel assembly and an anti-rolling assembly. The driving wheel assembly and the driven wheel assembly jointly constitute a clamping and conveying mechanism for the metal wire. The anti-rolling assembly comprises two side wall supporting discs which are symmetrically arranged on both sides of the metal wire and used for limiting the rolling of the metal wire in the horizontal plane. The problems of poor stability of fine metal wire conveying and difficulty in guaranteeing the quality of finished parts are solved.

This utility model relates to the technical field of wire feeding devices, and discloses a wire feeding device for the displacement of the wire feeding arm in a medium-speed wire cutting machine. It includes a base plate, a wire unloading device fixedly connected to the top left side of the base plate, a support frame fixedly connected to the top right side of the base plate, a guide tube two fixedly connected to the bottom left side of the support frame, a movable conductive block fixedly connected to the left side of the guide tube two, and an opening / closing wire clamping cylinder fixedly connected to the left side of the movable conductive block. A guide tube one is provided on the left side of the opening / closing wire clamping cylinder. In this utility model, the device uses the base plate as a foundation, and a stable frame is constructed through connecting plates and support plates. The height of the top plate one or the support plate is adjusted by a screw to change the wire feeding path. A displacement limiting block is used to limit the maximum movement distance of the wire. The entire device achieves efficient and stable wire feeding and cutting functions through precise control and coordination of the operation of each component, thus facilitating operation by the operator.
