Embodiment Construction

[0028] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0029] The embodiment of the present invention is an ultrasonic atomization spray forming system, which disturbs the molten metal flow through the vibration generated by the piezoelectric oscillator to break it into uniform droplets, and the metal droplets are accelerated by high-speed gas and quickly hit the receiver. By controlling the movement trajectory of the three-dimensional worktable, the metal droplets are deposited and solidified in different parts to prepare high-quality metal parts. The system consists of vacuum device, metal smelting device, atomization device, deposition device, control device and dust removal device, which respectively realize vacuum environment acquisition, metal smelting, metal melt atomization, deposition and solidification of metal droplets, three-dimensional workbench Functions such as stroke and motor switch control and colle...

Abstract

The invention relates to a spray forming system for preparing alloy and metal-based composite parts. The spray forming system is characterized in that: an intermediate frequency induction melting furnace, a transfer crucible, a high-pressure gas nozzle, a receiver, a three-dimensional workbench and an ultrasonic transducer tool head are arranged in a vacuum tank; the vacuum tank is connected witha vacuum machine through a pipeline, the side wall of the vacuum tank is provided with a feeding hole and a discharge hole, and the intermediate frequency induction melting furnace is fixed on a supporting plate through a melting furnace bracket and connected with a servo motor mechanism for controlling the movement of the intermediate frequency induction melting furnace; and the transfer crucible is arranged at the lower part of one side of the intermediate frequency induction melting furnace and connected with a diversion pipe through a threaded through hole in the bottom of the transfer crucible, and the ultrasonic transducer tool head is fixed on the fixed bracket. The spray forming system can effectively thin atomized granules and improve the metal yield, and is advanced and reliablein technical routes, low in production cost and easily controlled in product quality.

Description

technical field [0001] The invention relates to a spray forming system for preparing alloy and metal matrix composite material parts, and relates to a spray forming system for preparing high performance alloy and metal matrix composite material parts by applying ultrasonic atomization technology. Background technique [0002] Spray forming technology is an advanced forming technology developed in the past 30 years that uses rapid solidification method to directly prepare metal material blanks or semi-finished products. It mainly consists of continuous processes such as atomization of molten metal and deposition of atomized droplets. Spray forming technology belongs to the category of rapid solidification, which eliminates macro segregation and refines the structure, improves the performance of materials, especially the thermal processing performance of high-alloyed materials is improved; spray forming is directly transformed from molten metal into semi-finished products The ...
