Fuse deposition type 3D printing wire shearing device and operation method

Abstract

The invention relates to a fuse deposition type 3D printing wire shearing device and an operation method. The fuse deposition type 3D printing wire shearing device comprises a bottom plate, a blade mounting plate and a top plate, a motor is fixed on the upper surface of the top plate, and a cam is mounted on an output shaft at the tail end of the motor after penetrating through the top plate; a pit is formed in the upper surface of one end of the bottom plate, a blade mounting plate is placed at the pit, a roller is mounted on the top surface of the blade mounting plate, the roller and the cam are located at the same plane position, and the roller is in contact with a base ring of the cam; a first blade and a second blade which are opposite to each other are mounted on the bottom surface of the blade mounting plate, and the first blade and the second blade form a V-shaped cutting edge; and a flat blade is fixed to the upper surface of the bottom plate, and the cutting edge of the flat blade corresponds to the V-shaped cutting edge. Working is reliable, operation is easy and convenient, working efficiency is improved, and use requirements are met.

Description

technical field [0001] The invention relates to the technical field of shearing devices, in particular to a fused filament deposition type 3D printing wire shearing device and an operation method. Background technique [0002] 3D printing technology has gradually expanded from the initial mold manufacturing, industrial design and other fields to the direct manufacturing of some products. At present, this technology is widely used in many fields such as jewelry, footwear, industrial design, construction, automobile, aerospace, dentistry and medical industries. Applied. In aerospace and other fields, due to the high requirements for the strength of 3D printed parts, continuous fibers or other materials need to be added to the printed materials for modification. [0003] Fused filament deposition type 3D printing system, the filament is melted in the high-temperature nozzle, and filling materials are required during the printing process. The system feeds the filament into the ...

AI Technical Summary

Problems solved by technology

[0005] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a fused filament deposition type 3D printing wire shearing device and operation method, so that by adding a shearing device to the 3D printing system, the whole system can complete the processing of different materials. The cutting of filaments of different sizes effectively solves the problem of cutting filaments containing continuous fibers, expands the types of filaments that can be adapted to the 3D printing system, improves the stability of the 3D printing system, and improves the quality and performance of printed products
