Problems solved by technology
And in this process, argon only plays the role of protection, not the role of powder delivery
[0005]
Usually, both the synchronous method and the preset method are tested on the same machine, which leads to a problem, that is, during the preset cladding, the shielding gas is still sprayed from the powder feeding nozzle and meets the laser beam on the substrate. At this time, the protective gas does not play the role of conveying powder, and it is easy to blow off the pre-coating that has been preset and bonded to the substrate, resulting in random splashing of powder during preset and waste of powder

Embodiment Construction
[0026] refer to Figure 1 to Figure 5 , the preset operation box for laser cladding, the box body 1 is at least surrounded by a closed enclosure structure, and a cladding work area is set in the center of the box body, that is, a workbench 2 is set on the central work area of the bottom 11 of the box body. The No. 1 sensor 3 is set at the same height on the side of the workbench 2, the No. 2 sensor 4 is set on the top of the box body 1, and the No. 3 sensor 5 is set at the bottom corner of the box body 1; a plurality of air intake holes 12 are also set in the box body 1 , the plurality of air intake holes 12 surround the work area, more precisely, the air intake holes 12 are set on the bottom of the box, and surround the workbench 2, so that the working space is filled with protective gas; the plurality of air intake holes 12 Divided into areas, the protective gas tank 15 is connected through the area pipeline 13 and the flow electric valve 14; different areas can be provide...

The invention relates to an operation box for presetting of laser cladding. The periphery of a box body is at least of a closed enclosure structure, a cladding operation area is arranged in the middleof the box body, a first sensor is arranged on the operation area, a second sensor is arranged at the top of the box body, and a third sensor is arranged at the corner of the bottom of the box body;multiple gas inlet holes are further formed in the box body and surround the operation area; the multiple gas inlet holes pass through area pipelines and flow electric valves in a regional manner to be connected with a protection gas tank; and the first sensor, the second sensor and the third sensor are all oxygen sensors, signals collected by the oxygen sensors are connected with a plc, and the plc outputs and controls action of the area flow electric valves. According to the operation box, based on the argon use function principle during presetting of cladding, the conveying path of protection gas is changed, the content of gas in the box is monitored in real time to adjust the conveying amount of the protection gas, on one hand, direct blowing of powder is avoided, secondly, waste of the protection gas is reduced, and environment friendliness is good.
Description
Technical field: [0001] The invention belongs to the technical field, and in particular relates to a preset operation box for laser cladding. Background technique: [0002] Laser cladding principle: Laser cladding uses high-energy-density laser beams to rapidly fuse the added cladding material with the substrate, thereby improving the surface properties of the substrate. According to the different ways of adding materials, it is divided into two types: preset method and synchronous powder feeding method. [0003] Synchronous powder feeding method: At the beginning of the test, the laser emits laser light, so that the laser spot is irradiated on the substrate; the protective gas tank delivers the protective gas to the powder feeder, and the powder is sent to the powder feeding nozzle, and the gas and powder are sprayed from the powder feeding nozzle to the substrate together On the other hand, the laser spot converges on the substrate to realize the coaxiality of powder, lig...
