AI Technical Summary

Technical Problem

Existing automatic wire feeding devices for metal additive manufacturing are cumbersome to hold and fix the material rollers, require hydraulic pumps, have complex structures and high costs, are inconvenient to move, and have a small adjustment range.

Method used

It employs a clamping assembly and a displacement assembly. The clamping assembly uses a dual-head motor to drive the lead screw to rotate, thereby moving the moving block. Combined with a pressure sensing mechanism and controller, it achieves convenient clamping. The displacement assembly uses an electric push rod to push the mounting bracket to slide on the slide rail, increasing the range of motion.

Benefits of technology

It enables convenient clamping and movement of material rollers, avoids damage from clamping, expands the adjustment range of wire supplementation, and improves ease of use.

Abstract

This utility model discloses an automatic wire feeding device for metal additive manufacturing, belonging to the field of metal additive manufacturing technology. It includes a chamber, with a displacement component installed in an internal groove. A mounting frame is installed on the side of the displacement component, and a clamping component is installed in the middle of the mounting frame. A first self-driving slide rail is installed on the top of the side of the chamber away from the displacement component. The clamping component is used in this utility model. A roller wound with wire is placed in the middle of the mounting frame. A dual-head motor rotates, driving a lead screw to rotate. The lead screw drives a moving block to move. A clamping disc connected to the side of the moving block moves to clamp the roller wound with wire. Clamping is convenient. The pressure block moves within the clamping disc under the pressure of the roller. A buffer spring compresses, and the pressure block contacts a pressure sensor. The pressure sensor receives pressure and transmits a pressure signal to the controller. The controller stops the dual-head motor, allowing the clamping disc to hold the roller wound with wire, preventing damage.
