An auxiliary material supply synchronization mechanism for metal powder additive manufacturing equipment

Abstract

The invention discloses an auxiliary material supply synchronizing mechanism of metal powder additive manufacturing equipment. The auxiliary material supply synchronizing mechanism comprises a frame body, a disc-shaped transverse mounting plate is fixedly installed on the upper portion of the frame body, a barrel body is fixedly installed in the middle of the top of the mounting plate, a first vertical shaft is installed in the middle of the bottom of the barrel body, the lower end of the first vertical shaft is movably connected with a bottom bearing in the barrel body, a conical roller fixedly sleeves the position, close to the upper end, of the first vertical shaft, the small-diameter end of the conical roller faces upwards, the lower end of the first vertical shaft is fixedly sleeved with a driven gear, the inner bottom of the barrel body is fixedly provided with a vertical power motor, an output shaft of the power motor is fixedly provided with a driving gear, and the driving gearis matched with the driven gear in a meshed mode. According to the auxiliary material supply synchronizing mechanism, the output speeds of metal powder particles in different material cylinders can be linearly controlled through adjustment of corresponding electric telescopic rods, and the whole mechanism only needs one power motor to provide the power; and therefore, the auxiliary material supply synchronizing mechanism is simple in structure and convenient to use.

Description

technical field [0001] The invention belongs to the field of additive manufacturing equipment, in particular to an auxiliary material supply synchronization mechanism of metal powder additive manufacturing equipment. Background technique [0002] Existing methods for additive manufacturing of metal materials mainly use methods such as laser, electron beam heating, and arc heating to heat metal materials to complete rapid prototyping and additive manufacturing of parts. The existing selective laser sintering additive manufacturing method uses a laser to scan on the powder, melt the powder, accumulate and repeat the sintering molding layer by layer after solidification. There is also an additive manufacturing method that cooperates with an induction heating device to heat and melt metal powder particles. In this method, a variety of different metal powders can be used at the same time, and the process of additive manufacturing can be adjusted by controlling the feeding speed o...

Problems solved by technology

There is also an additive manufacturing method that cooperates with an induction heating device to heat and melt metal powder particles. In this method, a variety of different metal powders can be used at the same time, and the process of additive manufacturing can be adjusted by controlling the feeding speed of different metal powders. The ratio of different metal components in the forming layer, however, some equipment still needs a separate feeding device, and different metal powder feeding requires a separate feeding device to control the speed, which is not convenient enough
