Cylinder diameter-adjustable lifting device

Abstract

The invention discloses a cylinder diameter-adjustable lifting device. The cylinder diameter-adjustable lifting device comprises a lifting cabin outside cylinder, a forming cabin lifting mechanism, apowder feeding cabin lifting mechanism and a diameter-variable mechanism, wherein the forming cabin lifting mechanism comprises a forming cabin lifting motor, a forming cabin screw, a forming cabin guide pillar, a forming cabin lifting supporting plate and a forming cabin lifting base plate, the forming cabin lifting motor provides power for the forming cabin screw, and the forming cabin lifting motor is used for driving the forming cabin lifting supporting plate, the forming cabin guide pillar and the forming cabin lifting base plate to ascend; the powder supply cabin lifting mechanism comprises a powder supply lifting motor, a powder supply cabin screw, a powder supply lifting supporting plate and a powder supply base plate, the powder supply cabin lifting motor provides power for the powder supply cabin screw and is used for pushing the powder supply lifting supporting plate and the powder supply cabin guide pillar to ascend, and then the powder supply base plate is driven to ascend. The diameter-variable mechanism is used for narrowing a printing width, the cylinder diameter-adjustable lifting device is reasonable in structural design, can meet the requirements of research anddevelopment, production and manufacturing can be further considered, and the cylinder diameter-adjustable lifting device is suitable for massive popularization.

Description

technical field [0001] The invention relates to the technical field of selective laser melting equipment, in particular to a variable bore lifting device. Background technique [0002] Selected area laser melting is a laser additive manufacturing technology, which uses point-line-surface-body layer-by-layer manufacturing technology to realize rapid and free forming of parts without molds. SLM equipment lays a layer of metal powder on the substrate in advance, and then controls the laser to scan the layer of metal powder. The metal powder scanned by the laser is melted and solidified to form a dense metallurgical bond, while the metal powder that has not been scanned is still loose. The powder, through layer-by-layer circulation, is finally piled up to manufacture three-dimensional solid parts. SLM technology is mainly used in direct manufacturing of complex metal parts in aviation, aerospace, medical, mold and other industries. [0003] The core of SLM equipment is a high-...

Problems solved by technology

However, the needs of users such as universities and research institutes for the size change of the forming format are not considered. During the development of new products, the printing format is fixed, resulting in serious waste of materials, waste of development time, and low utilization of equipment.
