AUTOMATIC PREPARATION APPARATUS FOR CERAMIC PARTICLE REINFORCED METAL-MATRIX COMPOSITE PREFORM

摘要

Provided is an automatic preparation apparatus for a ceramic particle reinforced metal-matrix composite preform. The automatic preparation apparatus comprises a machine seat, a feeding component, a stirring component, a material weighing component, a material filling component, a conveying device, a metal mold cavity (12), a vibrating table (16), a curing device and a processor. A horizontal slide groove is provided in a side wall of the top of the machine seat, a support plate is arranged in the horizontal slide groove, and the feeding component is fixedly arranged on the support plate. The stirring component comprises a stirring material barrel (5) and a stirring paddle (6), the top of the stirring material barrel (5) is fixedly arranged below the support plate by means of a connecting member, and a lower end of the feeding component is in communication with the stirring material barrel (5). A driving motor I (18) is arranged in the middle of the support plate, and an output shaft of the driving motor I (18) is connected to the stirring paddle (6). The material weighing component and the material filling component are successively fixedly arranged at a lower end of the stirring material barrel (5), the vibrating table (16) is arranged right below the material filling component, the metal mold cavity (12) is arranged on the vibrating table (16), and the conveying device and the curing device are respectively arranged on two sides of the vibrating table (16). Further provided is a method for preparing a ceramic particle locally reinforced metal-matrix composite preform. The apparatus can reduce labor costs and improve the mechanical properties of a preform.
