Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] It should be understood that the orientation words in the present invention such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" etc. indicate the orientation or positional relationship It is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. In the absence of a contrary description, these orientation words do not indicate or imply that the referred device or element must have a specific Orientation or construction and operation in a specific orientation, so it cannot be construed as limiting the scope of protection of the invention; the orientation words "inner and outer" refer to the inside and outside relative to the outline of each component itself....

Abstract

The invention relates to a metal-powder removing device for 3D printing and aims to solve the problems of incomplete removing, potential safety hazards and serious waste, which are found in the existing powder removing devices or methods. The metal-powder removing device comprises an enclosed housing, a framework, a vibration device and a collection device, wherein the vibration device comprises astepper motor, a transmission rod, a deflecting plate, a vibration motor and a chuck; an output shaft of the stepper motor is connected with the transmission rod through a coupling; the transmissionrod is hinged with the deflecting plate; the chuck is connected to the deflecting plate through springs; the vibration motor is fixed on the chuck; an air pressure rod is arranged between the transmission rod and the deflecting plate; the collection device comprises a porous plate, a dust suction device and a powder collection container; the porous plate covers and connected to a dust suction inlet of the dust suction device; and the powder collection container is connected to a discharge outlet of the dust suction device. The enclosed housing is used to achieve a totally-enclosed design to reduce the direct contact between powder cleaning workers and powder; and the transmission rod is used to drive to-be-cleaned parts to rotate by nearly 720 degrees so as to achieve all-round powder removing.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, and in particular relates to a 3D printing metal powder cleaning equipment. Background technique [0002] 3D printing technology is a technology that can transform a three-dimensional model into a three-dimensional object in the shortest time. It is not limited by traditional processing. As long as the three-dimensional model can be designed, it can be produced in the shortest time. It is used in medical, aerospace, etc. fields are used. In the field of 3D printing technology, metal 3D printing (SLM) is the most widely used printing, which has the advantages of high material utilization rate, wide range of applicable materials, short production cycle, and the ability to manufacture parts with complex shapes. It has great advantages in the structural forming of pipelines, dense inclined holes, dense blind holes and complex cavities. However, after these complex structures are forme...
