Description

Technical Field

[0001] The utility model relates to the field of 3D printing, in particular to a steel plate used for a 3D printing platform. Background Art

[0002] 3D printing technology, also known as three-dimensional printing technology, is a technology that uses digital model files as the basis and uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. The surface of the existing platform steel plate used for 3D printing is usually flat and smooth, resulting in poor adhesion between the parts and the steel plate when 3D printing parts, which in turn causes the 3D printed parts to easily slide on the printing platform steel plate. For this reason, we propose a platform steel plate for 3D printing. Utility Model Content

[0003] The utility model aims to provide a 3D printing platform steel plate, comprising a platform steel plate main body, wherein a plurality of honeycomb holes are evenly penetrated through the platform steel plate main body, the bottom of the platform steel plate main body is fixedly connected to a support frame, and an auxiliary component is installed inside the support frame.

[0004] Preferably, a plurality of groups of honeycomb holes are combined on the platform steel plate body to form a honeycomb shape.

[0005] Preferably, the auxiliary component comprises an electric push rod, which is fixedly mounted on the bottom end of the inner wall of the support frame, the top of the support frame is fixedly connected to a lifting plate, and the top of the lifting plate is fixedly connected to a plurality of groups of evenly arranged top blocks.

[0006] Preferably: the number of the top blocks is the same as the number of the honeycomb holes, and the top blocks are aligned and matched with the honeycomb holes one by one. Preferably: four groups of guide components are arranged between the lifting plate and the support frame.

[0007] Preferably, the guide assembly comprises a guide sleeve, the guide sleeve is fixedly mounted on the bottom end of the inner wall of the support frame, the lower end of the T-shaped guide rod is slidably connected in the inner cavity of the guide sleeve, and the top end of the T-shaped guide rod is fixedly connected to the lifting plate.

[0008] Preferably, a limiting block is fixedly connected to the bottom end of the inner wall of the guide sleeve, and a limiting ring is fixedly connected to the top end of the inner wall of the guide sleeve.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The utility model forms a honeycomb shape by combining multiple groups of honeycomb holes on the platform steel plate body. The honeycomb shape is used on the platform steel plate body to increase the adhesion during printing, so that the adhesion between the parts and the platform steel plate body is increased during 3D printing of parts, so that the printed parts will not slide easily on the platform steel plate body; and the honeycomb shape on the platform steel plate body forms a honeycomb texture on the bottom of the printed parts, and the texture on the bottom of the printed parts is beautiful and smooth.

[0011] 2. When the 3D printing work is completed, some honeycomb holes will be attached with less oil or powder than the printing spray. At this time, starting the electric push rod will drive the lifting plate to move up, and the lifting plate will drive the top block to move up. The upward movement of the top block will push out the oil or powder attached to the honeycomb holes. When the T-shaped guide rod contacts the limit ring, the top of the top block will be flush with the top of the platform steel plate body 1, which is convenient for the user to clean the oil or powder on the top of the platform steel plate body.
