Abstract

The invention discloses rapid cooling type double-laser printing equipment in the field of intelligent manufacturing. The rapid cooling type double-laser printing equipment comprises a working cavity mounted on a rack, a heat preservation cavity is arranged above the working cavity, a laser head is arranged at the top end of the heat preservation cavity, a powder bed is arranged at the bottom end of the heat preservation cavity, and a powder spreading mechanism used for spreading powder on the powder bed and a heating mechanism used for heating the interior of the heat preservation cavity are arranged in the heat preservation cavity. A supporting plate used for containing a workpiece is arranged in the working cavity, the supporting plate is fixedly mounted on a lifting mechanism, and the supporting plate slides up and down along the inner wall of the working cavity. A cooling mechanism is arranged in the working cavity and used for cooling the formed area of the workpiece when the workpiece is machined. According to the equipment, the formed area of the workpiece can be rapidly cooled while the equipment prints the workpiece, the temperature of the non-formed area of the workpiece is not affected, powder cannot fly, cooling can be synchronously completed when the workpiece is printed, and the forming efficiency of the workpiece is improved.

Description

technical field [0001] The invention belongs to the field of intelligent manufacturing, and specifically relates to a fast-cooling dual-laser printing device. Background technique [0002] 3D printing (3D printing) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Selective laser sintering (Selective Laser Sintering, SLS) is to lay a layer of non-metallic powder material on the workbench in advance. Under the control of the computer, the laser sinters the solid part of the powder according to the interface contour information, and then continuously circulates and accumulates layer by layer. forming. This type of forming method has the characteristics of simple manufacturing process, high flexibility, wide range of material selection, low material price, high material utilization rate, and fast forming speed. However, this ...
