Photo-curing gradient material forming device and method

Abstract

The invention discloses a photo-curing gradient material forming device and method. The method is characterized in that a photo-curing groove is formed at a lower end of a forming platform, the forming platform is arranged at an upper end of the photo-curing groove through a vertical driving device, a photo-curing forming lamp panel is arranged at a lower end of the photo-curing groove, and a photo-curing forming material needed by printing is placed in the photo-curing groove; a mixing tank is connected with a feeding mechanism, density adjustment of the photo-curing forming material is realized, the mixing tank communicated with the photo-curing tank through a circulating pipeline is used for achieving flowing of a photo-curing forming material in the photo-curing tank, preparation of agradient material is achieved. The device is simple in structure, the preparation process of a traditional gradient material is simplified, manufacturing cost is reduced, conditions needed by formingof the gradient material are reduced, operation is easy, the device can realize preparation of density gradient materials with different performance requirements, only different fillers need to be added into the filler tank, and different fillers are added to improve performance requirements of different parts.

Description

technical field [0001] The invention relates to the technical field of gradient material preparation devices, in particular to a photocuring gradient material forming device and method. Background technique [0002] With the continuous development of high technology and the continuous change in the field of material science, density gradient materials have emerged as the times require. Density gradient material is a kind of functionally gradient material whose density changes gradually along the thickness direction. According to specific requirements, the functions of two or more sides can be realized under the premise of ensuring the integrity of the material, so as to meet the performance requirements of parts in different occasions. [0003] The preparation methods of density gradient materials include: chemical vapor deposition method, self-propagating high temperature synthesis method, plasma spraying method, powder metallurgy method, centrifugal casting method and film...

AI Technical Summary

Problems solved by technology

For example, there are problems such as the interface with a sudden change in composition and the low bonding strength of each coating between the coatings of the plasma spraying method; the vapor deposition method can only prepare thin layers, and it is difficult to obtain large-scale materials with a certain thickness; in addition, this type of preparation method process Complex, requires large equipment, cannot be carried out in the laboratory, and the cost is high, which is not conducive to research and production
