Problems solved by technology

However, this inert atmosphere protection box has the following obvious disadvantages: when forming and processing larger-sized parts, the size of the inert atmosphere protection box is also required to be large, so the processing and manufacturing requirements of this inert atmosphere protection box are very high, and the cost is expensive; at the same time , the inert atmosphere protection box needs to consume a large amount of inert gas to maintain the inert atmosphere in the box, and the operating cost is high
The advantages of this kind of inert atmosphere protection box are: flexible size design, small volume, and low cost, but the obvious disadvantages are: high work cost, and unsatisfactory protection effect

Embodiment Construction

[0024] The present invention provides an inert atmosphere protective box for laser preparation, processing and forming of metal materials. The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] attached figure 1 It is a schematic diagram of the CNC machine tool system using the present invention. The cylindrical box 1 is fixed on a bracket 9 with adjustable level and height, and straddles the bed surface of the CNC machine tool; a laser vertical laser that can reciprocate along the Z-axis direction is inserted in the first flange hole 2. Straight light guide tube, the lower end of the laser vertical light guide tube is equipped with a laser focusing lens holder and a powder feeding head, and 12 quick-connect jacks on the first flange hole 2 are inserted with cooling water pipes, air pipes and powder pipes. To cool the laser focusing mirror and deliver protective gas and powder to the powder feeding head; a...

Abstract

The invention belongs to the field of the metallurgical machinery, which more particularly relates to an inert atmosphere protective box used for preparing, processing and forming metallic materials by laser. The external circumferential wall of a box body is provided with 7 flange holes, and a motion small platform is arranged in the box body. A numeral control machine is connected with the motion small platform through connecting rods inserted into the flange holes. A workpiece is fixed behind the motion small platform and inert gases are pumped into the box body after the box body is vacuumized. The numeral control machine controls the track of the motion small platform, and a laser completes the processing and formation of parts. The box body can be designed in a target-oriented way according to the dimension of the processed parts, which has flexible design and small dimension. The consumed inert gas is little, and the operating cost is low; as the parts are fixed on the horizontal connecting rod which can rotate, the laser processing and formation of the rotational parts can be realized. The invention also has the characteristics of good protection effect and low cost.

Description

technical field [0001] The invention belongs to the field of metallurgical machinery, in particular to an inert atmosphere protection box used for laser preparation, processing and forming metal materials. Background technique: [0002] In the process of laser preparation, processing and forming metal materials, if the oxygen content in the ambient atmosphere is not well controlled (the oxygen content must be controlled below 100PPm), the high-temperature melt in the laser molten pool will interact with the oxygen in the ambient atmosphere. A chemical reaction occurs or active oxygen atoms diffuse into the lattice of the metal material, which increases the oxygen content of the metal oxide or metal material in the metal material prepared, processed and formed by laser, which greatly affects the laser preparation, processing materials and formed parts. mechanical properties. For example, when the oxygen content of the TC4 alloy does not exceed 0.2% (weight percent), its elon...
