Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial processing, in particular to a laser cutting equipment for fireplace shell surface processing. BACKGROUND

[0002] As a household product with both practical and decorative functions, the fireplace shell is not only a key component for protecting the internal combustion structure, but its appearance quality also directly affects the overall appearance and quality of the entire fireplace, thereby affecting the purchasing decision of consumers.

[0003] Traditional fireplace shell surface processing methods, such as mechanical cutting and stamping forming, have many limitations. During mechanical cutting, the cutter directly contacts the material, which can easily generate a large cutting force. This not only causes burrs and deformation on the edges of the material, affecting the flatness and precision of the shell, but also increases the production cost and time cost of replacing the cutter due to cutter wear. Although stamping forming can achieve processing of certain shapes, it has limited processing capacity for complex patterns and delicate structures, making it difficult to meet the market demand for diversified and personalized design of fireplace shells.

[0004] With the continuous development of laser technology, laser cutting has been widely used in the field of metal processing due to its unique advantages. Laser cutting uses a high-energy-density laser beam to irradiate the processed material, causing it to rapidly heat up to vaporization temperature, evaporating to form a hole. With the relative movement of the light beam and the material, the cutting is finally achieved. This method has the advantages of high cutting precision, fast cutting speed, good cutting surface quality, and the ability to process complex patterns. However, the existing laser cutting process uses a one-end feeding and the other-end discharging method, which is a single assembly line process, resulting in slow efficiency and long idle time for feeding and discharging. SUMMARY

[0005] To solve the above technical problems, the present application discloses a laser cutting equipment for fireplace shell surface processing. The present application discards the traditional one-end feeding and the other-end discharging method and adopts a rotary feeding and discharging method. Four feeding and discharging ports are provided, with two opposite ports in each group and synchronized. A double-head laser head is also provided, which can simultaneously cut two processing raw materials. While one group is cutting, the other group is feeding and discharging, eliminating idle time and allowing the two groups to work alternately, reducing processing time and increasing efficiency. When feeding and discharging, the magnetic attraction of the horizontal slide block I is moved to quickly move the processing raw materials between the preparation area and the processing area. The drive of the horizontal slide block I is achieved by rotating the rotating rod, which causes the sleeve slide block on the rotating rod to be connected to the horizontal slide block I, thereby driving the horizontal slide block I to slide. The two opposite horizontal slide blocks I can be simultaneously driven by the sleeve slide blocks at both ends of the rotating rod.

[0006] A laser cutting device for processing the surface of a fireplace casing includes a table, a feeding rack, and a door-shaped frame. Four cutting racks are fixedly installed on the upper part of the table. The upper edge of the cutting rack is rolled inward, and a guide rail is provided on the lower edge of the cutting rack. The cutting rack is hollow in the middle. A guide plate is fixedly installed on the lower edge of the inner ring of the cutting rack. A feeding plate is fixedly installed close to the lower edge of the outer side of the cutting rack. The raw material to be processed is also slidably placed on the cutting rack.

[0007] Preferably, the feeding rack is provided with a guide rail similar to that below the cutting rack, and the two guide rails are seamlessly connected. A limit frame is fixedly installed on the feeding rack, and the inner side of the limit frame contacts the outer side of the raw material being processed. A horizontal slider I is also slidably installed on the guide rail of the feeding rack.

[0008] Preferably, a side plate is also fixedly installed on the feed rack, and a slide rod is provided on the side plate. A horizontal slider II is slidably installed on the slide rod. The horizontal slider II is threadedly connected to a lead screw. Both ends of the lead screw are rotatably installed in the round holes of the fixed plate on the side plate. One end of the lead screw is also connected to the motor shaft of the stepper motor I. The stepper motor I is fixedly installed on the fixed plate on the side plate. A square hole is also provided in the middle of the horizontal slider II. A lever is inserted into the square hole and contacts the outermost processing raw material.

[0009] Preferably, a long shaft is fixedly installed at the middle of the lower edge of the platform, and a rotating rod is rotatably installed on the long shaft. A gear is provided at the lower edge of the rotating rod, and the gear meshes with the motor gear of stepper motor II. Stepper motor II is fixedly installed on a fixed plate on the long shaft. Sleeve sliders are slidably installed at both ends of the rotating rod. Strong magnets are embedded on the upper edge of the sleeve sliders, and magnetic shielding plates are slidably installed on the sleeve sliders. The lower edge of the magnetic shielding plates is fixedly connected to the piston rod of cylinder I. Cylinder I is fixedly installed at the lower edge of the sleeve sliders.

[0010] Preferably, a drive assembly is fixedly installed on the gantry frame, and a laser head is rotatably installed on the lower side of the drive assembly. The laser head has parallel heads that are opposite in direction.

[0011] Preferably, a stop bar is slidably mounted on the other side of the stepper motor I, one end of which is fixedly connected to the piston rod of the cylinder II, and the cylinder II is fixedly mounted on the stepper motor I.

[0012] Preferably, a strong magnetic component is installed on the upper side of the horizontal slider I. The strong magnetic component will hold the lower side of the raw material being processed and magnetically attract it. At the same time, a strong magnet is also embedded in the lower side of the horizontal slider I.

[0013] The beneficial effects of this invention compared with the prior art are: 1. When using this invention, the traditional method of feeding at one end and discharging at the other end is abandoned. Instead, a rotary feeding and discharging device is adopted, with a total of four loading and unloading ports. Two diagonally opposite ports are grouped together and operated synchronously. Combined with a dual-head laser head, it can simultaneously laser cut two raw materials. While one group is cutting, the other group is loading and unloading, eliminating downtime and allowing the two groups of working processes to alternate, reducing processing time and increasing efficiency.

[0014] 2. In the process of loading and unloading materials, the present invention uses a horizontal slider I to move the raw materials by magnetic attraction, so that the raw materials can move quickly between the preparation area and the processing area. The horizontal slider I is driven by the rotation of the rotating rod, so that the sleeve slider on the rotating rod connects with the horizontal slider I, thereby driving the horizontal slider I to slide. The horizontal sliders I on both sides diagonally can be synchronously driven by the sleeve sliders at both ends of the rotating rod. Attached Figure Description

[0030] In one optional embodiment of the present invention, such as Figure 3 , Figure 4 , Figure 5 As shown, four cutting frames 2 are fixedly installed on the table 1. The upper edge of the cutting frame 2 is rolled inward. The lower edge of the cutting frame 2 is equipped with a guide rail. The middle of the cutting frame 2 is hollow.

A material feeding plate 3 is fixedly installed close to the lower edge of the outer side of the cutting frame 2. The raw material 5 is also slidably placed on the cutting frame 2.

[0031] In one optional embodiment of the present invention, such as Figure 6 , Figure 7 As shown, the feeding rack 6 is equipped with a guide rail that is the same as the one below the cutting rack 2. The two guide rails are seamlessly connected. A limit frame 7 is fixedly installed on the feeding rack 6. The inner side of the limit frame 7 is in contact with the outer side of the raw material 5. A horizontal slider I 8 is also slidably installed on the guide rail of the feeding rack 6.

[0032] In one optional embodiment of the present invention, such as Figure 7 As shown, a side plate 9 is also fixedly installed on the feed rack 6. A slide rod is provided on the side plate 9, and a horizontal slider II 12 is slidably installed on the slide rod. The horizontal slider II 12 is threadedly connected to the lead screw 10. The two ends of the lead screw 10 are rotatably installed in the round holes of the fixed plate on the side plate 9. One end of the lead screw 10 is also connected to the motor shaft of the stepper motor I 11. The stepper motor I 11 is fixedly installed on the fixed plate on the side plate 9. A square hole is also provided in the middle of the horizontal slider II 12. A lever 13 is inserted into the square hole. The lever 13 contacts the outermost processing material 5.

[0033] In one optional embodiment of the present invention, such as Figure 9 , Figure 10 As shown, a long shaft 19 is fixedly installed at the middle of the lower side of the platform 1. A rotating rod 14 is rotatably installed on the long shaft 19. A gear is provided on the lower side of the rotating rod 14. The gear meshes with the motor gear of the stepper motor II 18. The stepper motor II 18 is fixedly installed on the fixed plate on the long shaft 19. Sleeve sliders 15 are slidably installed at both ends of the rotating rod 14. A strong magnet is embedded on the upper side of the sleeve slider 15. A magnetic shielding plate 16 is slidably installed on the sleeve slider 15. The lower side of the magnetic shielding plate 16 is fixedly connected to the piston rod of the cylinder I 17. The cylinder I 17 is fixedly installed on the lower side of the sleeve slider 15.

[0034] In one optional embodiment of the present invention, such as Figure 11 As shown, a drive assembly 21 is fixedly installed on the gantry frame 22, and a laser head 20 is rotatably installed on the lower side of the drive assembly 21. The laser head 20 has parallel heads with opposite directions.

[0035] In one optional embodiment of the present invention, such as Figure 8 As shown, a stop bar 23 is slidably mounted on the stepper motor I11 on the other side. One end of the stop bar 23 is fixedly connected to the piston rod of the cylinder II24, which is fixedly mounted on the stepper motor I11.

[0036] In one optional embodiment of the present invention, such as Figure 6 , Figure 10As shown, a strong magnetic component is installed on the upper side of the horizontal slider I8. The strong magnetic component will hold the lower side of the processing raw material 5 in place and magnetically attract it. At the same time, a strong magnet is also embedded in the lower side of the horizontal slider I8.

[0037] Working Principle: In use, this invention can simultaneously cut two raw materials 5. Multiple raw materials 5 are prepared on the four corner feed racks 6. The first raw material 5 is held in place by a strong magnet on the horizontal slider I8. First, the stepper motor II 18 starts, driving the rotating rod 14 to rotate counterclockwise. When the two sleeve sliders 15 on the rotating rod 14 rotate to below the diagonally opposite horizontal slider I8, the strong magnet below the horizontal slider I8 and the strong magnet above the sleeve slider 15 are attracted without contact. The rotating rod 14 continues to rotate, and the sleeve sliders 15 drive the horizontal slider I8 to slide on the guide rails on the feed rack 6 and the cutting rack 2. Due to the continuous rotation of the rotating rod 14, the sleeve sliders 1... 5 will slide inward on the rotating rod 14 to adapt to the trajectory of the guide rail until the raw material 5 is brought into the cutting frame 2, which is the working state. Then the laser head 20 is started, and the drive component 21 drives the laser head 20 to cut on the raw material 5. The raw materials 5 on both sides will be cut with the same pattern. The guide rail under the cutting frame 2 is slightly tilted outward, so the raw material 5 is also tilted outward. The waste material after cutting falls through the guide plate 4 to the unloading plate 3. This cutting method is only limited to cutting symmetrical patterns because the two raw materials 5 facing each other are placed symmetrically. If the pattern is not symmetrical, the cut-out position of the raw material 5 will be opposite.

[0038] During the cutting period, the magnetic shield 16 slides under the drive of the cylinder I17, blocking the sleeve slider 15 and the horizontal slider I8, thus disconnecting the sleeve slider 15 from the horizontal slider I8. After disconnection, the magnetic shield 16 can be reset, and the rotating rod 14 continues to rotate counterclockwise, moving to the bottom of the other two sets of symmetrical horizontal sliders I8. Similarly, it moves the other two sets of raw materials 5 into the cutting frame 2 for processing. After positioning, the rotating rod 14 rotates clockwise back to the bottom of the first set of horizontal sliders I8, and the sleeve slider 15 continues to be connected to the first set of horizontal sliders I8 through the action of the magnetic shield 16.

[0039] After the first set of cuts is completed, the laser head 20 will rotate 90 degrees to cut another set of raw materials 5. During the cutting process, the first set will be unloaded and reloaded. The rotating rod 14 will rotate clockwise, bringing the cut raw materials 5 back to their original position on the feed rack 6. Then, the cylinder II 24 will start, causing the stop rod 23 to extend and block the raw materials 5. Then, the rotating rod 14 will rotate counterclockwise. Since the raw materials 5 are blocked by the stop rod 23, the horizontal slider I 8 will be driven to slide off the raw materials 5. Then, the stepper motor I 11 will start, bringing... The moving screw 10 rotates, thereby driving the horizontal slider II 12 to slide. The lever 13 on the horizontal slider II 12 pushes the raw material 5 inward, which will push out the cut raw material 5. The pushed-out raw material 5 will fall onto the adjacent feed plate 3, waiting to be picked up manually. Then the sleeve slider 15 moves again to the bottom of the horizontal slider I 8, driving the horizontal slider I 8 to move to the bottom of the raw material 5 in the preparation area and suck it up. Repeat the initial steps to send the raw material 5 into the cutting frame 2. By repeating this process, the alternation of two sets of cutting can be completed.
