Linear cutting device for 3D printing metal false tooth

Abstract

The invention relates to the field of false tooth machining, in particular to a wire cutting device for 3D printing of metal false teeth, which comprises an annular conveying track arranged on a support and a wire cutting machine, a machined part is specifically a false tooth printed on a base disc, and the annular conveying track is respectively provided with a feed port and a discharge port. An adjusting arm with a clamping mechanism is further arranged on the support, a rotating driving device and a lifting driving device which are used for driving the adjusting arm to rotate and driving the adjusting arm to vertically move are further arranged on the support, and the fixing device comprises a containing mechanism, a freezing mechanism and a pressing mechanism. According to the denture cutting machine, through cooperation between the containing mechanism and the freezing mechanism and downward pressing of ice blocks frozen together through the downward pressing mechanism, stability of a basal disc and a denture is achieved when the denture cutting machine cuts the denture, the situation that the root of the denture is uneven when the denture is cut is avoided, the denture cutting efficiency is improved, and the denture cutting machine is suitable for large-scale production. And the completeness of the false tooth is ensured.

[0002] 3D printing (3DP) is a kind of rapid prototyping technology. 3D printing is usually realized by using digital technology material printers. It is often used to manufacture models in mold manufacturing, industrial design and other fields, and is gradually used for direct manufacturing of some products. , There are already parts printed using this technology. Since this technology can produce objects of almost any shape, and the accuracy and restoration are extremely high, it is quickly applied in the field of denture production. Using 3D printed dentures, and repairing The position of the teeth and gums fits extremely well, and has been widely used by denture manufacturing companies. In the prior art, dentures are generally manufactured by metal 3D printing. After the metal 3D printing is completed, the root of the denture will be fixed. On the base plate integrally formed with the denture, in the final processing, it is necessary to use a wire cutting machine to cut off each denture from the base plate, and finally polish the surface of the denture. The problem with this method is that one On the one hand, due to the irregular curved surface structure of the bottom of the denture during cutting, it is easy to cut out the perforation at the bottom of the denture, and it is easy to make it shake during the cutting process, resulting in uneven cutting

[0004] According to the above-mentioned patent, when cutting and processing dentures in this patent, it is only necessary to place multiple pieces of substrates to be cut on the storage table at one time, and then use the retrieving mechanism to intermittently take out each piece of substrates to be cut. Put it on the fixing device, and the fixing device using electromagnetic adsorption can automatically absorb the substrate to be cut and processed, so that the cutting device set on the workbench can cut the denture integrally formed on the substrate, and the denture after cutting is directly Falling, after the cutting is completed, control the fixing device to cut off the power to release the adsorption and fixing effect on the cut substrate, so that the substrate can fall automatically, and finally use the pick-up mechanism to pick and place the substrate to be cut again. However, this The patent cannot guarantee the stability of the denture when cutting the denture. When the denture is gradually separated from the base plate, the denture is prone to deflection, which eventually leads to uneven cutting of the denture. Steady denture cutter while cutting
