Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0020] like figure 1 Shown is a schematic diagram of the structure of the multifunctional inert gas protective atmosphere box. The interior of the box 1 is divided into two parts: an upper processing chamber and a lower powder collection chamber by a middle partition 18 . Exhaust holes 5 and temperature monitoring holes 6 are arranged on the left side panel of the box body 1, and air inlet holes 4 and air pressure monitoring holes 3 in the box are arranged on the right side panel. The opening positions of each hole can be determined according to the setting of the experimental equipment, and are not limited to the above positions. The upper cover of the box body 1 is a sealed soft top 2 that allows the laser head 10 and the coaxial powder feeding head 11 to pass through. There is an opening in the middle of the sealed soft top 2. The opening...

Abstract

A multifunctional gas protection atmosphere case for laser cladding formation. The case body mainly comprises two parts of a protection chamber and a powder collection chamber. The protection chamber is provided with a processing platform with an adjustable height. A processing chamber is enclosed by a front and a back baffle plate, a left side plate, a right side plate, an intermediate clapboard, and an upper sealing soft material. a gas outlet and a temperature monitoring hole are disposed on the left side plate, and a gas inlet and a pressure monitoring hole are disposed on the right side plate. Besides the processing platform, the intermediate clapboard is provided with a powder collection hole which can be opened or closed and is communicated with the power collection chamber at the lower layer. The invention is applicable to laser processing where the processing platform is fixed and a laser head freely moves with a robot, and especially applicable to the laser cladding and formation process of high-temperature easily-oxidized materials; as for powder feeding laser cladding formation, the invention also has the function of powder recovery, which saves experimental materials. Additionally, the case body has a small volume and a light weight, and has excellent characteristics of energy saving, environmental protection, and easy carrying.

Description

technical field [0001] The invention relates to a multi-functional gas protection device in the field of laser processing, in particular to a multi-functional protection box used for laser cladding forming by powder feeding using easily oxidized powder materials or base materials. Background technique [0002] In the field of laser processing, the high temperature oxidation of processed materials is an important issue that affects processing quality and product performance. In the laser cladding and laser forming processing using the powder feeding method, when the cladding material or the base material is a high-temperature easy-to-oxidize material such as a refractory metal, the problem of anti-oxidation during the processing must be solved. The anti-oxidation method in the prior art mainly relies on adding inert gas or vacuum protection device. One type is a vacuum protection room that includes the entire laser processing system (including laser head, platform, robot, et...
