[0002] Porous metal material is a metal material with a high porosity, usually composed of a metal matrix and pores distributed in the matrix. Due to its unique structure, porous metal materials are often used in aerospace, automobile and other fields. Laser welding, as an efficient and precise connection technology, is widely used in the connection and processing of metal materials, especially the processing of porous metal materials.

[0030] The anti-oxidation component includes a cylinder 34 and an air storage box 41. The outer side of the cylinder 34 is fixedly connected to the right side of the top cover 2. The cylinder 34 is used to extract and transport the anti-oxidation gas. The cylinder 34 is slidably connected to a piston 35. The piston 35 is used to slide to change the air pressure at the bottom of the cylinder 34. Two one-way valves 36 are fixedly connected to the bottom of the cylinder 34. The one-way valves 36 are used to ensure the one-way flow of gas. The bottom of the air storage box 41 is fixedly connected to the inner bottom wall of the chassis 1.

An air pipe 13 is installed between the left one-way valve 36 and the air storage box 41, and an air pipe 13 is installed between the right one-way valve 36 and the front side of the laser 10 to ensure that the anti-oxidation gas can be effectively transported from the inside of the air storage box 41 to the surface of the metal material during laser welding.

[0031] The end of the connecting rod 33 away from the rotating frame 32 passes through the cylinder 34 and is fixedly connected to the upper side of the piston 35, so that the piston 35 can slide back and forth through the reciprocating sliding of the connecting rod 33, thereby changing the air pressure at the bottom of the cylinder 34. The gas stored in the gas tank 41 is argon, which has good protective properties and can effectively prevent oxidation of materials during laser processing.

[0032] The cooling component includes a water tank 39 and a water pump 42. The water tank 39 is fixedly connected to the upper side of the base frame 1. The water tank 39 is used to store water. A filter 40 is fixedly connected to the upper side of the water tank 39. The filter 40 is used to filter the used water resources into metals. The water pump 42 is fixedly connected to the rear side of the base frame 1. The water pump 42 is used to extract water. A water pipe 14 is installed between the input end of the water pump 42 and the inside of the water tank 39. A water pipe 14 is installed between the output end of the water pump 42 and the front side of the laser 10 to ensure that during the laser welding process, water can be effectively transported to the welding point of the metal material through the water pipe 14 to cool it down.

[0033] A grille 38 is fixedly connected to the upper side of the base frame 1, and the grille 38 facilitates the flow of cooled water into the water tank 39. Two inclined plates 37 are fixedly connected to the bottom side of the top cover 2. The bottom of the inclined plate 37 fits in with the outer side of the baffle 18, so that the baffle 18 can make contact with the bottom of the inclined plate 37 for a certain period of time, so that the baffle 18 slides and drives the sliding rod 17 to slide to press the metal material.

[0034] Working principle: When it is necessary to perform laser welding on porous metal materials, the first electric push rod 4 is controlled to start through the control panel on the right side of the top cover 2. The first electric push rod 4 starts to drive the protective door 3 to slide, so that the metal material can be placed inside the top cover 2 for laser welding. By placing the metal material on the upper side of the grille 38 and using the second electric push rod 8 on the control panel, the second electric push rod 8 slides to drive the bracket 9 to slide, and further drives the laser 10 to slide. After the laser 10 is adjusted to the appropriate position, the first motor 6 and the second motor 11 are started again. The first motor 6 rotates to drive the screw rod 43 to rotate, and the screw rod 43 rotates to drive the mounting bracket 7 to slide linearly. The mounting bracket 7 slides and drives the laser 10 to perform sliding welding. At the same time, the sliding of the mounting bracket 7 will also drive the connecting block 15 to slide. The sliding of the connecting block 15 drives the fixed rod 16 to slide. The sliding of the fixed rod 16 drives the sliding rod 17 and the blocking rod 18 to slide. In the process of sliding, the blocking rod 18 will slide downward under the action of the inclined plate 37. The downward sliding of the blocking rod 18 further drives the sliding rod 17 to slide downward, causing the mounting block 23 to slide downward and drive the pressure plate 28 to slide. The pressure plate 28 will first contact the metal surface, and then drive the connecting rod 27 to rotate, causing the two slides 25 to slide and squeeze the second spring 26. At the same time, due to the elastic force of the second spring 26 itself, the two slide plates 25 are pushed to slide, driving the connecting rod 27 to rotate, so that the pressure plate 28 slides downward to press the metal material. During the pressing process, the soft plate 29 can reduce the damage caused by the pressing. The second motor 11 rotates to drive the grinding disc 12 to rotate, and the laser welded parts are polished. The screw rod 43 also drives the disc 44 to rotate while rotating. The rotation of the disc 44 drives the eccentric shaft 30 to rotate. The rotation of the eccentric shaft 30 drives the rotating frame 32 to slide up and down, further driving the connecting rod 33 to slide up and down. The connecting rod 33 slides up and down to drive the movable The plug 35 slides up and down, and the piston 35 slides up and down to change the air pressure at the bottom of the cylinder 34, and extracts the argon gas inside the air storage tank 41 through the one-way valve 36 and transports it to the surface of the metal material in front of the laser 10. During the laser welding process, the water pump 42 is started, and the water inside the water tank 39 is extracted by the water pump 42 and transported to the front of the laser 10 through the water pipe 14 to cool the welding part to prevent the metal material from being damaged by excessive temperature. The used water will follow the debris generated by welding through the grille 38 and fall into the upper side of the filter 40. The filter 40 will filter the debris and make the water fall into the water tank 39, thereby reducing the waste of water resources.
