[0002] Metal composite plate is a composite material formed by combining two or more different metal materials by physical or chemical methods. It usually has excellent mechanical properties, corrosion resistance and lightweight characteristics, and is widely used in aerospace, automobile manufacturing, construction and other fields.

Metal composite plates are usually composed of different types of metals. The melting points, thermal conductivity and mechanical properties of various metals vary greatly, making it difficult to control the heat-affected zone during laser processing, resulting in thermal stress concentration in the material, which makes it more prone to deformation or cracking.

[0038] For example, in one embodiment: the air inlet 18 is connected to an external air pump through a pipeline.

[0039] For example, in one embodiment: when laser punching is required, the metal composite plate is placed on the punching fixture 40 located at the top of the lifting and conveying assembly 30, and then the two clamping and adjusting motors 421 are started, so that the two adjusting clamps 42 move to the side of the clamp mounting frame 41, so that the adjusting clamps 42 are clamped on the conveyor belt 32, and then the conveying motor is started to drive the driving wheel 112 to rotate, thereby driving the conveyor belt 32, and then driving the punching fixture 40 to move to one end of the driving wheel 112 until it moves to the punching position, and then the longitudinal drive motor, the transverse drive motor and the vertical regulator are started in sequence to drive the laser cutter 21 to move to the position to be cut, and at the same time, the preheating lamp 22 will be started to preheat the metal composite plate below. When the temperature is raised to the preheating temperature, the laser cutter 21 will start to perform punching cutting. At the same time, the external air pump will start to deliver uniform temperature airflow and deliver it into the cavity inside the ventilation frame 15 along the air inlet 18. Then, the two air volume regulating cylinders 153 will start, causing the output shaft of the air volume regulating cylinder 153 to retract, causing the air volume regulating plug plate 152 to move accordingly, thereby opening the air volume regulating slot 151, so that the uniform temperature airflow will be delivered along the cavity inside the ventilation frame 15 to the multiple air outlet triangular frames 16, and then flow out from the multiple air outlet strip slots 17 to blow the bottom of the metal composite plate at a uniform temperature.

[0040] When the metal composite plate is placed on multiple plate placement strips 44, the metal composite plate will push the multiple vertical supporting strips 451 to move downward along the vertical slide groove 447, so that the bottom surface of the metal composite plate is supported on the top corner of the placement triangle piece 442. At the same time, when the vertical supporting strip 451 moves downward, the push rod 455 will follow the movement, so that the push force of the push rod 455 on the linkage rotating strip 453 disappears, so that the linkage rotating strip 453 will rotate and move downward under the action of the torsion spring, so as to pull the linkage rotating column 456 to follow the movement, so that the arc-shaped air guide block 452 follows and slides along the arc-shaped slide groove 454. When the uniform temperature airflow blows the bottom of the metal composite plate to be cut, the uniform temperature airflow will impact the air guide net 444, causing the air guide net 444 to slightly rotate and move upward, guiding the uniform temperature airflow to move obliquely upward, and guided by two inclined expansion surfaces 459 and the arc-shaped air guide groove 458, directly impacting the metal composite plate to be cut, and centrally and quickly equalizing the temperature of the metal composite plate to be cut, thereby preventing the metal composite plate from overheating due to excessive laser power or too slow cutting speed.

[0041] For example, in one embodiment, after the uniform temperature airflow impacts the metal composite plate to be cut, it will go back to the outer end of the air guide net 444 so that it remains in a slightly inclined upward position. After the metal composite plate is cut and punched, the position where the punching is disconnected will be bounced open under the elastic force of the rebound spring 450 of the multiple vertical supporting strips 451. At the same time, the multiple vertical supporting strips 451 will move upward along the vertical slide groove 447, so that the push rod 455 will move accordingly, and then push the linkage rotating strip 453 to rotate accordingly, so that the arc-shaped air guide block 452 will move upward along the arc-shaped slide groove 454, and then guide the uniform temperature airflow to move toward the position to be cut, thereby improving the temperature uniformity during cutting. At the same time, since the position where the punching is disconnected is pushed open, the uniform temperature airflow that returns to the outer end of the air guide net 444 is reduced, so that the air guide net 444 will rotate downward under the action of the adjusting spring 446, and then become inclined downward, further improving the intensity and uniformity of the uniform temperature airflow directed to the position to be cut, and ensuring the uniform cooling rate of the material during the cutting process.

[0042] Installation process: Install the cutting bed 11 on one end of the ground, slide the two sides of the bottom surface of the horizontal adjustment beam 12 in the two longitudinal adjustment rails 111 respectively, slide the top of the longitudinal adjuster 13 away from the end of the conveying motor in the horizontal adjustment rail 121, install the laser cutter 21 in the vertical sliding plate 132, install the preheating lamp 22 at the bottom of the horizontal adjustment beam 12, install the lifting and conveying assembly 30 at the other end of the installation ground, stack the two punching fixtures 40 in the lifting and conveying assembly 30 at intervals along the height direction, slide the inner sides of the two adjustment clamps 42 on both sides of the fixture mounting frame 41 adjacent to the driving wheel 112, and install the two longitudinal adjustment beams 13 in the vertical sliding plate 132.

At the same time, the concentrated blowing of the uniform temperature airflow and the guidance of the punching fixture 40 can effectively prevent the material from overheating due to excessive laser power or slow cutting speed, thereby reducing the risk of thermal deformation.
