Embodiment 1

[0040] An active backflush cleaning device for selective laser melting manufacturing, such as figure 1 As shown, it includes a cabinet body 1 and a support mechanism 2 supporting the cabinet body 1 .

[0041] The support mechanism 2 includes adjustable foot cups 20 and casters 21. Four adjustable foot cups 20 are respectively installed at the apex of the lower surface of the cabinet body 1, and four casters 21 are respectively installed on the insides of the four adjustable foot cups 20. . Slide the active backflush cleaning equipment to the corresponding SLM equipment through the casters 21, adjust the height of the adjustable foot cup 20, and fix the active backflush cleaning equipment horizontally on the ground. The casters 21 are used in conjunction with the adjustable foot cups 20. When it is necessary to move the gas circulation purification continuous operation equipment used for laser selective melting manufacturing, the adjustable foot cups 20 are lifted so that the ...

Abstract

The invention discloses active back-blowing cleaning equipment for a selective laser melting manufacturing. The active back-blowing cleaning equipment comprises a cabinet body and a filtrating devicearranged in the cabinet body, wherein the filtrating device is connected between an air intake and an air return port of a forming chamber of a SLM equipment; the filtrating device comprises at leastone filter element; a back-blowing device which is used for blowing air from inside to outside is arranged in the filter element; an air inlet of the back-blowing device communicates with an air tankfor supplying inert gas to the air inlet of the back-blowing device; an air outlet communicates with the outside through a bleeding port arranged on the cabinet body; a valve set for selecting gas toenter the air return port or discharging the gas to air through the bleeding port is arranged between the bleeding port and the air return port; and the back-blowing device can be used for reversely blowing smoke dust particulate matter on the filter element so as to remove the particles blocked on the filter element, and replacement of the filter element during one-time printing process of the SLM equipment is avoided.

Description

technical field [0001] The invention relates to the field of additive manufacturing, in particular to an active back-blowing cleaning device for selective laser melting manufacturing. Background technique [0002] Selective Laser Melting SLM (Selective Laser Melting) technology is a method of metal additive manufacturing. The processing material used in SLM technology is metal powder with a particle size of about 15 μm-50 μm. During the processing, the laser emits laser light, which is processed by the optical system and then irradiates the processing plane. Under the control of the control system, the laser light is processed on the powder bed made of metal powder according to the contour curve calculated by the STL file imported into the system. Scanning, which melts the metal powder to form the finished product. [0003] Since the SLM equipment molding chamber cannot reach an absolutely airtight state, during the process of laser scanning the powder bed, the metal powde...
