Abstract

The invention relates to a base plate dimension adjustment device for powder feeding under double cylinders. The base plate dimension adjustment device comprises a forming cylinder adjustment device (1) and a powder cylinder adjustment device (2), wherein the forming cylinder adjustment device (1) comprises a support frame I (4), a support plate I (5), an inner cylinder I (6), an inner cylinder bottom plate I (7), a connection rod I (8) and a base plate (9); the forming cylinder adjustment device is arranged in the outer cylinder (3) of a forming cylinder and located on the upper part of an outer cylinder bottom plate (10) of the forming cylinder; the powder cylinder adjustment device (2) comprises a support frame II (12), a support plate II (13), an inner cylinder II (14), an inner cylinder bottom plate II (15) and a connection rod II (16); and the powder cylinder adjustment device is arranged in the outer cylinder (11) of a powder cylinder and located on the upper part of an outer cylinder bottom plate (17) of the powder cylinder. The base plate dimension adjustment device disclosed by the invention increases the powder utilization rate of a powder spreading plane, reduces the powder use amount, and lowers the base plate expense and the powder use cost.

Description

technical field [0001] The invention relates to a 3D printing device, in particular to a double-cylinder bottom powder feeding type selection melting device. Background technique [0002] Additive manufacturing, also known as 3D printing, has become one of the most concerned advanced manufacturing technologies after nearly 30 years of rapid development. Compared with the traditional method of obtaining parts by removing materials, additive manufacturing technology does not require molds, has a shorter cycle from design to finished product, and is not limited by structure and materials. Due to the above advantages, additive manufacturing technology is praised by some European and American experts. In order to lead the disruptive technology of the "Third Industrial Revolution", a large amount of manpower and financial resources have been invested in research, and it has been widely used in aerospace, automotive, medical and other industries. [0003] Existing metal additive m...
