Technical Field

[0001] The present invention relates to the technical field of metal cutting equipment, and particularly provides a laser punching device for metal composite plates. Background Art

[0002] A metal composite plate is a composite material formed by combining two or more different metal materials through physical or chemical methods. It usually has excellent mechanical properties, corrosion resistance, and light weight, and is widely used in fields such as aerospace, automobile manufacturing, and construction. During the laser processing, the laser beam will generate high temperature on the material surface, causing rapid heating of the local area, which is likely to lead to thermal deformation or phase change of the material. Moreover, the metal composite plate is usually composed of different types of metals, and there are significant differences in the melting point, thermal conductivity, and mechanical properties of various metals, making it difficult to control the heat-affected zone during laser processing, resulting in thermal stress concentration of the material, and thus more likely to occur deformation or cracking.

[0040] For example, in one embodiment: The air inlet hole 18 is connected to an external air pump through a pipeline.

[0041] 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. Subsequently, two clamping adjustment motors 421 are started, so that the two adjustment clamps 42 move towards the side of the fixture mounting frame 41, so that the adjustment clamps 42 are clamped on the conveyor belt 32. Subsequently, 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 towards one end of the driving wheel 112 until it moves to the punching position. Subsequently, the longitudinal driving motor, the transverse driving motor and the vertical regulator are started in sequence to drive the laser cutter 21 to move to the position to be cut. At the same time, the preheating and warming lamp 22 will be started to preheat and warm the metal composite plate below. When the temperature rises to the preheating temperature, the laser cutter 21 will be started for punching and cutting. At the same time, an external air pump will be started to convey a uniform temperature air flow, and it will be conveyed into the cavity inside the ventilation frame 15 along the air inlet hole 18. Subsequently, two air volume adjustment cylinders 153 will be started, so that the output shafts of the air volume adjustment cylinders 153 retract, so that the air volume adjustment plug 152 moves accordingly, thereby opening the air volume adjustment groove 151, so that the uniform temperature air flow will be conveyed along the cavity inside the ventilation frame 15 to the plurality of air outlet triangular frames 16, and then flow out from the plurality of air outlet strip-shaped grooves 17 to blow the bottom of the metal composite plate evenly.

[0042] When the metal composite plate is placed on multiple plate placement strips 44, the metal composite plate will push the multiple vertical abutting strips 451 to move downward along the vertical sliding groove 447, so that the bottom surface of the metal composite plate abuts against the top corners of the placement triangular pieces 442. At the same time, when the vertical abutting strips 451 move downward, the abutting push rods 455 will move accordingly, so that the abutting thrust of the abutting push rods 455 on the linkage rotating strips 453 disappears, and the linkage rotating strips 453 will rotate and move downward under the action of the torsion spring, and then pull the linkage rotating columns 456 to move accordingly, and further make the arc-shaped air guiding blocks 452 slide along the arc-shaped sliding grooves 454. When the uniform temperature air flow blows on the bottom of the metal composite plate to be cut, the uniform temperature air flow will impact the air guiding net 444, so that the uniform temperature air flow will impact the air guiding net 444, making the air guiding net 444 rotate slightly upward, guiding the uniform temperature air flow to move obliquely upward, and through the guiding of the two inclined diffusing surfaces 459 and the arc-shaped air guiding grooves 458, directly impact the metal composite plate to be cut, uniformly heat the metal composite plate to be cut intensively and quickly, and prevent the metal composite plate from overheating due to too high laser power or too slow cutting speed.

[0043] For example, in one embodiment: after the uniform temperature air flow impacts the metal composite plate to be cut, it will wind back to the outer end of the air guiding net 444, so that it remains in a slightly inclined upward position. When punching the metal composite plate, the punched and disconnected position will be sprung open under the elastic force of the return springs 450 of the multiple vertical abutting strips 451. At the same time, the multiple vertical abutting strips 451 will move upward along the vertical sliding groove 447, and then the abutting push rods 455 will move accordingly, and then push the linkage rotating strips 453 to rotate accordingly, and then make the arc-shaped air guiding blocks 452 move upward along the arc-shaped sliding grooves 454, and then guide the uniform temperature air flow to move to the cutting position, improving the uniformity of the temperature during cutting. At the same time, since the punched and disconnected position is pushed open, the uniform temperature air flow winding back to the outer end of the air guiding net 444 is reduced, and the air guiding net 444 will rotate downward under the action of the adjusting spring 446, and then becomes inclined downward, further improving the intensity and uniformity of the uniform temperature air flow guiding to the cutting position, and ensuring the uniformity of the cooling speed of the material during the cutting process.

[0044] Installation process: Install the cutting bed body 11 at one end of the ground. The two sides of the bottom surface of the horizontally placed adjusting beam 12 are respectively slidably installed in two longitudinal adjusting slide rails 111.

The laser cutter 21 is installed in the vertical sliding plate 132. The preheating and warming lamp 22 is installed at the bottom of the horizontally placed adjusting beam 12. Install the lifting and conveying assembly 30 at the other end of the installation ground.

[0045] The present invention can achieve:

[0046] 1.

At the same time, through the concentrated blowing of the uniform temperature air flow and the guiding of the punching jig 40, it can effectively prevent the material from overheating caused by too high laser power or too slow cutting speed, and reduce the risk of thermal deformation.

[0047] 2. The present invention can effectively guide the uniform temperature air flow to the cutting position to reduce the temperature of the heat affected zone. At the same time, it can also adjust the uniform temperature air flow at the cut position and guide it to the position to be cut, maintaining the temperature uniformity of the cutting area, so as to provide uniform cooling and precise temperature control, avoiding embrittlement or other performance degradation of some materials in the metal composite plate caused by overheating, and extending the service life of the material.
