Example Embodiment

[0053] Such as figure 1 As shown, it includes a powder storage module 1, a powder spreading module 2, a symmetrical linear walking module 3, a residual material recovery module 4 and a horizontal workbench 5. The powder storage module 1 is located above the workbench 5 and is connected to the horizontal through supports 1-3 The workbench 5 is fixedly connected to store metal powder and deliver the metal powder to the powder spreading module 2 in time. Two identical linear electric cylinders 3-3 in the symmetrical linear walking module 3 are symmetrically arranged on both sides of the forming chamber 6. And fixedly connected to the horizontal workbench 5, while the moving connection end 3-3-1 of the linear electric cylinder is fixedly connected with the powder spreading module 2. The two linear electric cylinders 3-3 are carried out by the motor 3-1 and the corresponding transmission mechanism. Synchronous drive is used to drive the powder spreading module 2 to perform linear rec...

Abstract

The invention relates to a powder laying device for electron beam titanium alloy powder fusion forming, and belongs to the field of precision additive manufacturing. A powder storage module is locatedabove a workbench and fixedly connected with the horizontal workbench through a supporting part for storing metal powder and conveying metal powder to a powder laying module, two same linear electriccylinders in symmetrical linear walking modules are symmetrically arranged on the two sides of a forming chamber and fixedly connected to the horizontal workbench, meanwhile, the mobile connection ends of the linear electric cylinders are fixedly connected with the powder laying module, and two vertical recycling barrels in an excessive material recycling module are arranged on the two sides of apowder storage box correspondingly and fixedly connected with the workbench and the powder storage box. The device has the advantages that a powder layer is uniform, flat and high in density, the problem that a pressing roller cannot smoothly pass through metal splash particles and is locally warped is solved, the powder laying effect of the device is greatly improved, and meanwhile the experiment or product machining success rate is improved.

Description

technical field [0001] The invention belongs to the field of precision additive manufacturing, and in particular relates to a powder spreading device for melting and forming electron beam titanium alloy powder powder (hereinafter referred to as titanium alloy electron beam 3D printing). Background technique [0002] With the rapid development of intelligent additive manufacturing technology, metal 3D printing technology has been applied and developed in many industries. Metal 3D printing devices are classified according to the heat source, which can be mainly divided into laser type and electron beam type. Compared with laser 3D printing technology, electron beam 3D printing technology has advantages such as higher output power and scanning speed, and better preheating effect. It has great development prospects. Titanium alloy electron beam 3D printed human implants have extremely wide application requirements in biomedical fields such as stomatology, neurosurgery, cardiova...
