[0012] The present invention provides a laser cutting device for the production and processing of mechanical components. It has the following beneficial effects:

[0013] 1. For the laser cutting device for the production and processing of mechanical components, an electric water pump is provided. The water flow is driven by the electric water pump and sprayed through the water spraying component. The water spraying component sprays the water flow on the surface of the arc-shaped guide plate, and under the action of gravity, it spontaneously flows on the surface of the arc-shaped guide plate, thereby driving the metal jet after cutting to move, cooling the metal jet and driving the metal jet to move along the flow of water, so as to bring the metal debris formed by cooling the metal jet into the interior of the filtering device, thereby filtering the water flow, separating the water from the metal debris. When the electric water pump is started, the electric water pump pumps the water from the interior of the filtering device, driving the water flow to reach the interior of the water spraying component from the bottom of the filtering device through the first water pipe for the recycling of water.

[0014] 2. For the laser cutting device for the production and processing of mechanical components, a water inlet housing is provided. The water flow passes through the interior of the water inlet housing and is filtered through the surface of the loop-shaped filter screen under the action of gravity. The loop-shaped filter screen filters the water body, separating the water body from the metal debris. The loop-shaped design of the loop-shaped filter screen increases the contact area with the water body, so that the amount of debris that can be carried is larger, and at the same time, it avoids the blockage of the filter screen caused by the accumulation of debris, thereby prolonging the service life. The filter guide plate cooperates with the fixing frame to fix the position of the filter housing. The arc-shaped design of the water collecting pool makes the water flow spontaneously gather on one side of the water collecting pool under the action of gravity, facilitating the extraction by the electric water pump. The design of the filter box and the first slide bar enables the filter box to be directly pulled out for convenient cleaning of the filter housing.

[0015] 3. For the laser cutting device for the production and processing of mechanical components, an electric water pump is provided. The water flow moves under the driving action of the electric water pump, flows through the interior of the second water pipe, enters the interior of the rotary joint and is discharged from the water outlet hole through the water outlet pipe, so as to discharge the water flow. Under the reaction force of the discharged water, the rotary joint is driven to rotate, so that the water flow rotates and sprays spontaneously when spraying, so that the water covers the surface of the arc-shaped guide plate and continuously flushes the surface of the arc-shaped guide plate, thereby driving the metal jet to move and driving the water to flow at the same time. The rotary spraying of water is realized, so that the water covers the surface of the arc-shaped guide plate to cool the metal jet received on the surface of the arc-shaped guide plate.

[0016] 4. The laser cutting equipment for the production and processing of mechanical parts is provided with a fan assembly. The air inside the heat dissipation blades enters the inside of the porous pipe through the inside of the heat dissipation housing under the driving action of the fan assembly, reaches the inside of the filter assembly for filtration, and then enters the air outlet pipe along the bottom of the fan assembly to eject the filtered air. When the laser emitter moves, the laser emitter drives the air outlet pipe to move. The bottom of the air outlet pipe directly contacts the top of the workpiece. The first telescopic rod provides elasticity to make the air outlet pipe closely adhere to the surface of the workpiece, so that the air is ejected through the holes provided on the side of the air outlet pipe and directly sprayed on the cutting position to clean the metal jet. The air enters the inside of the air opening through the side of the porous pipe and is filtered through the surface of the concave filter net under the driving action of the fan assembly to separate the air from the dust. The fixing ring is used to limit the position of the concave filter net, and the positioning block is used to fix the angle of the filter pipe, so that the air opening cooperates with the holes opened on the side of the porous pipe. The first handle facilitates the overall extraction of the filter pipe for cleaning, and the second handle facilitates the removal of the concave filter net for cleaning. The concave design of the concave filter net is beneficial to increasing the contact area with the air, thereby prolonging the service life of the concave filter net. And after filtration, the concave design is beneficial to dust collection. And the design of multiple concave filter nets is beneficial to grading and cumulative treatment of dust, so as to be beneficial to prolonging the service life and avoiding dust accumulation on the same filter net causing blockage.

The rotation of the first gear ring drives the reversing gear to rotate. The rotation of the reversing gear drives the second gear ring to rotate. The rotation of the second gear ring drives the reverse fan blades to rotate. The electric fan and the reverse fan blades rotate to drive the air to reach the inside of the conical air duct through the top of the fan housing and enter the inside of the air outlet pipe for discharge. The electric fan makes the rotation directions of the electric fan and the reverse fan blades opposite through the cooperation of the first gear ring and the reversing gear. Through the angle design of the electric fan and the reverse fan blades, the air is introduced into the inside of the conical air duct from the top of the fan housing, thereby increasing the air flow rate. And the rotation centers of the electric fan and the reverse fan blades are on the same straight line, and the rotation speeds of the electric fan and the reverse fan blades are the same, so as to cancel out the eccentric force brought by the torque to keep the operation state of the fan housing stable and reduce the influence of the vibration brought by the electric fan on the laser emitter, thereby improving the cutting accuracy.

[0030] The bottom plate bracket 1 provides overall support for the device. The cooling device 2 makes the water flow and filters it, so that the metal jet directly enters the water flow for cooling. The moving device 3 drives the laser emitter 4 to move to different positions. The heat dissipation device 5 dissipates heat from the laser emitter 4, drives the air on the surface of the laser emitter 4 to flow, thereby reducing the temperature of the laser emitter 4 for long-term operation, and filters the air and then sprays the air near the cutting part, so as to blow away the metal fluid in the first time to accelerate the cutting progress, and at the same time cool the cutting part in time to improve the cutting efficiency.

[0031] The cooling device 2 includes a water tank frame 201, an arc-shaped guide plate 202 is fixedly connected to the inner wall of the water tank frame 201, an electric water pump 203 is fixedly connected to the side of the water tank frame 201, a first water pipe 204 is connected to the bottom of the electric water pump 203, one end of the first water pipe 204 away from the electric water pump 203 is connected to a filtering device 205, the side of the filtering device 205 is connected to the side of the water tank frame 201, a water spraying assembly 206 is fixedly connected to the top of the arc-shaped guide plate 202, the water spraying assembly 206 penetrates through the side of the water tank frame 201 and is fixedly connected to the side of the water tank frame 201, the side of the water spraying assembly 206 is connected to the side of the electric water pump 203, the bottom of the water tank frame 201 is fixedly connected to the top of the bottom plate bracket 1, and the top of the filtering device 205 is fixedly connected to the bottom of the moving device 3.

[0032] Start the mobile device 3 and the laser emitter 4 to cut the metal sheet. The metal jet generated during cutting directly falls on the top of the arc-shaped deflector 202. The water flow is ejected through the water spraying assembly 206 driven by the electric water pump 203. The water spraying assembly 206 sprays the water flow on the surface of the arc-shaped deflector 202, and spontaneously flows on the surface of the arc-shaped deflector 202 under the action of gravity, thereby driving the cut metal jet to move, cooling the metal jet and driving the metal jet to move along the flow of water, so as to bring the metal debris formed by cooling the metal jet into the interior of the filtering device 205, thereby filtering the water flow, separating the water from the metal debris. Start the electric water pump 203, and the electric water pump 203 pumps the water from the interior of the filtering device 205, thereby driving the water flow to reach the interior of the water spraying assembly 206 from the bottom of the filtering device 205 through the first water pipe 204 for recycling of the water flow.

[0033] Please refer to Figure 1 - Figure 5 , the present invention provides a technical solution: the filtering device 205 includes an inlet housing 2051, a first slide bar 2052 is fixedly connected to the side surface of the inlet housing 2051, a filter box 2053 is slidably connected to the inner wall of the inlet housing 2051 through the first slide bar 2052, a fixing frame 2054 is fixedly connected to the inner wall of the filter box 2053, a filter box assembly 2055 is slidably connected to the inner wall of the fixing frame 2054, a sump 2056 is communicated with the bottom of the inlet housing 2051, the side surface of the sump 2056 is communicated with the side surface of the first water pipe 204, the side surface of the inlet housing 2051 is fixedly connected to the side surface of the water tank frame 201, and the top of the inlet housing 2051 is fixedly connected to the bottom of the laser emitter 4.

[0034] The filter box assembly 2055 includes a filter housing 20551, a return filter screen 20552 is fixedly connected to the inner wall of the filter housing 20551, a filter deflector 20553 is fixedly connected to the top of the filter housing 20551, and the side surface of the filter housing 20551 is slidably connected to the inner wall of the fixing frame 2054.

[0035] The water flow passes through the inside of the water inlet housing 2051 and is filtered through the surface of the loop-shaped filter screen 20552 under the action of gravity. The loop-shaped filter screen 20552 filters the water body, separating the water body from the metal debris. The loop design of the loop-shaped filter screen 20552 increases the contact area with the water body, enabling a larger amount of debris to be carried, while preventing debris accumulation from clogging the filter screen, thereby extending the service life. The filter guide plate 20553 cooperates with the fixing frame 2054 to fix the position of the filter housing 20551. The arc-shaped design of the water collecting pool 2056 causes the water flow to spontaneously gather on one side of the water collecting pool 2056 under the action of gravity, facilitating extraction by the electric water pump 203. The design of the filter box 2053 and the first sliding strip 2052 enables the filter box 2053 to be directly pulled out for easy cleaning of the filter housing 20551.

[0036] The water spraying assembly 206 includes a second water pipe 2061. A rotary joint 2062 is connected to the top of the second water pipe 2061. A water outlet pipe 2063 is connected to the side of the rotary joint 2062. Water outlet holes 2064 are formed in the side of the water outlet pipe 2063. The side of the second water pipe 2061 penetrates through the side of the pool frame 201 and is connected to the side of the electric water pump 203.

[0037] The water flow moves under the driving action of the electric water pump 203, flows through the inside of the second water pipe 2061. The water enters the inside of the rotary joint 2062 and is discharged from the water outlet holes 2064 through the water outlet pipe 2063, thereby discharging the water flow. Under the reaction force of the water discharge, the rotary joint 2062 is driven to rotate, causing the water flow to rotate and spray spontaneously when spraying, so that the water covers the surface of the arc-shaped guide plate 202 and continuously flushes the surface of the arc-shaped guide plate 202, thereby driving the metal jet to move and driving the water to flow simultaneously. The rotary spraying of water is achieved, so that the water covers the surface of the arc-shaped guide plate 202 to cool the metal jet received on the surface of the arc-shaped guide plate 202.

[0038] Please refer to Figure 1 - Figure 8 , the present invention provides a technical solution: The heat dissipation device 5 includes a heat dissipation housing 501. Heat dissipation fins 502 are fixedly connected to the side of the heat dissipation housing 501. A fan assembly 504 is connected to the bottom of the heat dissipation housing 501. The bottom of the laser emitter 4 is fixedly connected to the fixed end of a first telescopic rod 505. The movable end of the first telescopic rod 505 is fixedly connected to an air outlet pipe 506.

A first handle 5033 is fixedly connected to the middle position at the top of the filter tube 5031. An air opening 5034 is formed in the side surface of the filter tube 5031. A fixing ring 5035 is fixedly connected to the inner wall of the filter tube 5031. A concave filter net 5036 is slidably connected to the inner wall of the filter tube 5031. A second handle 5037 is fixedly connected to the top of the concave filter net 5036. The bottom of the concave filter net 5036 contacts the top of the fixing ring 5035. The side surface of the filter tube 5031 is slidably connected to the inner wall of the porous tube 507.

[0040] During the process of the laser emitter 4 emitting laser, the laser emitter 4 continuously operates to generate heat and transfer it to the heat dissipation fins 502. The fan assembly 504 is started. The air inside the heat dissipation fins 502 enters the inside of the porous tube 507 through the inside of the heat dissipation housing 501 under the driving action of the fan assembly 504, reaches the inside of the filtering component 503 for filtering, and then enters the air outlet pipe 506 along the bottom of the fan assembly 504, so as to eject the filtered air. When the laser emitter 4 moves, the laser emitter 4 drives the air outlet pipe 506 to move. The bottom of the air outlet pipe 506 directly contacts the top of the workpiece. The first telescopic rod 505 provides elasticity to make the air outlet pipe 506 closely adhere to the surface of the workpiece, so that the air is ejected through the holes provided on the side surface of the air outlet pipe 506 and directly sprayed on the cutting position to clean the metal jet. The air enters the inside of the air opening 5034 from the side surface of the porous tube 507 and is filtered through the surface of the concave filter net 5036 under the driving action of the fan assembly 504, so as to separate the air from the dust. The fixing ring 5035 is used to limit the position of the concave filter net 5036. The positioning block 5032 is used to fix the angle of the filter tube 5031, so that the air opening 5034 cooperates with the holes opened on the side surface of the porous tube 507. The first handle 5033 facilitates the overall extraction of the filter tube 5031 for cleaning. The second handle 5037 facilitates the removal of the concave filter net 5036 for cleaning. The concave design of the concave filter net 5036 is beneficial to increasing the contact area with the air, thereby prolonging the service life of the concave filter net 5036. And after filtering, the concave design is beneficial to the collection of dust. And the design of multiple concave filter nets 5036 is beneficial to the hierarchical accumulation treatment of dust, thereby being beneficial to prolonging the service life and avoiding the blockage caused by the accumulation of dust on the same filter net.

Through the cooperation of the first toothed ring 5043 and the reversing gear 5044, the rotation directions of the electric fan 5042 and the reverse fan blade 5047 are opposite. Through the angle design of the electric fan 5042 and the reverse fan blade 5047, air is introduced from the top of the fan housing 5041 into the inside of the conical air duct 5048, thereby increasing the air flow rate. Moreover, the rotation centers of the electric fan 5042 and the reverse fan blade 5047 are on the same straight line, and the rotation speeds of the electric fan 5042 and the reverse fan blade 5047 are the same, thereby canceling out the eccentric force brought by the torque, thus maintaining the stable operation state of the fan housing 5041 and reducing the influence of the vibration brought by the electric fan 5042 on the laser emitter 4, thereby improving the cutting accuracy.
