Description

Technical Field

[0001] The present application relates to the technical field of bed frame production, and in particular to a laser cutting machine for bed frame production. Background Art

[0002] When producing a bed frame, it is necessary to select suitable metal materials according to the design and purpose of the bed frame, such as cold-rolled steel plates, angle irons, square tubes, round tubes, etc.; then, according to the bed frame design drawings, use a cutting machine to cut the metal materials into the required size and shape, such as columns, beams, guardrails and other accessories; finally, use welding equipment to weld and assemble the metal parts to form the main structure of the bed frame.

[0003] When producing the bed frame of an apartment bed, the crossbeams of the bed frame are usually welded and assembled with square tubes, and the square tubes are usually cut and cut by a laser cutting machine. When cutting, the rotating chuck inside the laser cutting machine clamps the square tube so that the square tube is suspended and extended to a certain length, and then the laser cutting head emits a laser beam to melt the cut part of the pipe, and at the same time blows out the molten metal liquid through a high-pressure airflow. At this time, the molten metal liquid is easy to splash and adhere to the inner wall of the square tube under the action of the high-pressure airflow. In the prior art, a shielding rod is usually placed inside the pipe to reduce the probability of metal chips adhering to the inner wall of the pipe.

[0004] Referring to the Chinese patent document with the announcement number CN118455782B, the name is a tube laser cutting device, which includes a cutting table, multiple support components and a shielding rod. The support component can support the cut tube, so that the shielding rod can be suspended inside the tube, which can protect the inner wall of the tube and reduce the probability of metal chips adhering to the inner wall of the tube.

[0005] With reference to the above technical solution, the rear end of the pipe is supported by a supporting assembly so that the shielding rod can be suspended inside the pipe to protect the inner wall of the pipe; since the shielding rod needs to be installed inside the pipe, for pipes with a small diameter and a long length, such as the square beam of the bed frame, the shielding rod is difficult to install during use, and during subsequent material cutting, the shielding rod needs to be pulled out from the inside of the pipe, which requires a large operating space and makes material cutting more troublesome; in addition, cooling gas can be introduced into the pipe through the feeding end of the pipe to quickly blow the molten metal and slag generated during the cutting process away from the cutting area to prevent them from solidifying or adhering to the inner wall of the pipe again, but when cutting the square beam of the bed frame, due to its small diameter and long length, it is difficult for the cooling gas to blow the molten metal and slag out of the pipe. Instead, it will blow the molten metal and slag to deeper into the pipe, making the subsequent cleaning of metal chips inside the pipe more troublesome, affecting the efficiency and quality of the bed frame production. Summary of the invention

[0006] In view of this, the present application provides a laser cutting machine for bed frame production, which is used to solve the problem that it is difficult to clean the metal chips adhering to the inner wall of the pipe after cutting the cross beam of the bed frame, thereby affecting the production efficiency and quality of the bed frame.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will combine the Figures 1-8 of the embodiments of the present application to clearly and completely describe the technical solutions of the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present application.

[0030] Referring to Figure 1 and Figure 2 and, this embodiment provides a laser cutting machine for bed frame production, including a frame 1, an adjusting mechanism, and a clamping assembly 6; a laser cutting head 101 for cutting pipes is arranged at the upper end of the frame 1, a first rotating chuck 102 and a second rotating chuck 103 are respectively arranged inside the frame 1, the first rotating chuck 102 and the second rotating chuck 103 are used to support the cutting part of the pipe, the first rotating chuck 102 cooperates with an external feeding mechanism to support and feed the pipe to be cut, and a driving source can drive the first rotating chuck 102 to rotate actively, so as to realize the rotary cutting of the pipe.

[0031] Referring to Figure 1 and Figure 2, the adjusting mechanism includes a mounting base 2, a turntable 21, a positioning disc 3 and a limiting component 4. The mounting base 2 is slidably connected to the upper end of the frame 1 through a slide rail. The turntable 21 is rotatably connected to the inside of the mounting base 2. The positioning disc 3 is hinged to the left side of the turntable 21. The positioning disc 3 is used to position the extending length of the pipe. A scraping knife 31 is provided on the convex shaft at the center of the left side surface of the positioning disc 3. The scraping knife 31 can be inserted into the inside of the pipe to clean the inner wall of the pipe; the limiting component 4 includes a plug rod 41 and a cylinder 43. The plug rod 41 is slidably connected to the inside of a square hole provided at the center of the turntable 21. The cylinder 43 is fixedly installed at the center of the right side surface of the mounting base 2 through a U-shaped frame. The end of the telescopic shaft of the cylinder 43 is rotatably connected to the right end of the plug rod 41. The cylinder 43 is used to drive the plug rod 41 to slide left and right. A pin shaft 411 is provided at the left end of the plug rod 41. A notch 42 is provided on the right side of the positioning disc 3. The pin shaft 411 is located inside the corresponding notch 42 on the same side.

[0032] Referring to Figure 3 and Figure 4 , a gas ring 32 is rotatably connected to the middle of the positioning disc 3. The gas ring 32 is communicated with an air hole 33 in the middle of the positioning disc 3. External cooling gas can enter the inside of the pipe through the gas ring 32 and the air hole 33 to cool down the metal chips entering the inside of the pipe.

[0033] The pipe to be cut is conveyed from left to right through an external feeding mechanism, so that the pipe passes through the first rotating chuck 102 and the second rotating chuck 103 in sequence. At this time, under the driving action of the cylinder 43, the plug rod 41 slides to the right, so that the pin shaft 411 at the end of the plug rod 41 moves to the right end of the notch 42, so that the pin shaft 411 and the hinge shaft of the positioning disc 3 are in a horizontally misaligned state, which can ensure that the positioning disc 3 and the turntable 21 are in a parallel state. When the pipe is conveyed to abut against the positioning disc 3, it can play a role in positioning the maximum extending position of the pipe, which is convenient for the fixed-length cutting of the pipe; at the same time, the scraping knife 31 at the center of the left side surface of the positioning disc 3 is inserted into the inside of the pipe, which can clean the inner wall of the pipe and make the right end of the pipe communicate with the air hole 33, which is convenient for subsequently introducing gas into the pipe to cool down the molten metal chips and blowing the metal chips to the left side of the pipe cut, which is convenient for subsequently cleaning the metal chips adhered to the inner wall of the pipe.

[0034] Referring to Figure 5 , Figure 6 and Figure 7, the clamping assembly 6 includes a mounting bracket 61, adjusting bolts 63 and a locking unit 7. The mounting bracket 61 is slidably connected to the left side of the positioning disk 3. The number of mounting brackets 61 is two. Inside both of the two mounting brackets 61, there is a rotatably connected roller 62. The adjusting bolts 63 are rotatably connected inside the mounting brackets 61. The adjusting bolts 63 are respectively threadedly connected to the screw holes correspondingly arranged at the edge of the positioning disk 3. The adjusting bolts 63 are used to adjust the positions of the mounting brackets 61 and the rollers 62, so that the rollers 62 can abut against the outer side of the pipe. The locking unit 7 is arranged at the left edge of the positioning disk 3. The locking unit 7 cooperates with the transmission gears 621 arranged at the ends of the rotating shafts of the rollers 62 to lock the rollers 62, thereby realizing clamping and fixing of the pipe through the rollers 62. The locking unit 7 includes a chute plate 71, a sliding plate 72, a limiting rack 73 and a spring pin 74. The chute plate 71 is arranged at the left edge of the positioning disk 3. The sliding plate 72 is slidably connected inside the chute plate 71. The limiting rack 73 is adjustably mounted on the outer side of the sliding plate 72 by bolts. The number of limiting racks 73 is two. The two limiting racks 73 are respectively meshed and connected with the transmission gears 621 correspondingly arranged at the ends of the rollers 62. The spring pin 74 is arranged inside the chute plate 71. There is a card slot on the outer side of the sliding plate 72 that cooperates with the spring pin 74 for clamping. In the middle of the sliding plate 72, there is a lever 721. The lever 721 is located in the limiting groove 711 arranged in the middle of the chute plate 71. At the upper end of the frame 1, there is a limiting plate 75 corresponding to the positions of the spring pin 74 and the lever 721.

[0035] When the pipe is conveyed to abut against the positioning disk 3, the outer side of the pipe first contacts the roller 62 inside the mounting bracket 61. As the pipe is conveyed, under the action of friction, the roller 62 rotates. At the same time, the transmission gear 621 on the outer side of the roller 62 drives the limiting rack 73 and the sliding plate 72 to slide to the right along the chute plate 71 until the end of the pipe abuts against the positioning disk 3. At this time, the end of the spring pin 74 cooperates with the card slot on the outer side of the sliding plate 72 for clamping, thereby limiting the sliding plate 72 and locking the roller 62 through the cooperation of the limiting rack 73 and the transmission gear 621, and further realizing clamping and fixing of the end of the pipe through the roller 62.

[0036] Refer to Figure 1 and Figure 3 , in the middle of the mounting seat 2, there is a first motor 8. The first motor 8 can drive the turntable 21 to rotate through a gear transmission method, driving the pipe to rotate self - sufficiently, which is convenient for cutting the pipe. At the upper end of the mounting seat 2, there is a second motor 9. The second motor 9 can drive the mounting seat 2 to slide left and right through the cooperation of a gear and a rack.

[0037] Refer to Figure 1 and Figure 2, inside the frame 1, the bars 5 are arranged in left and right arrays. The bars 5 are made of aluminum, which can protect against the collision of the pipes. The bars 5 are all inclined upward from front to back, facilitating the automatic arrangement of the pipes after they fall. Inside the frame 1, a collecting plate 104 corresponding to the vertical position of the bars 5 is provided for collecting the debris discharged from the inside of the pipes.

[0038] When cutting the pipe, the mounting bracket 61 and the rollers 62 can support the tail end of the pipe, preventing the pipe from dropping directly when it is cut and improving the precision of the cutting part of the pipe; after the pipe is cut, the mounting seat 2 moves to the right, and at the same time, the cylinder 43 works, driving the plug rod 41 to slide to the left, so that the pin shaft 411 at the end of the plug rod 41 moves to the left end of the notch 42. At this time, the pin shaft 411 and the hinge shaft of the positioning disk 3 are in the same axis state. At this time, since the right end of the pipe is in a clamped state, under the action of the self-weight of the pipe, the left side of the cut pipe inclines downward and contacts the bar 5 inside the frame 1 (refer to Figure 8 ), facilitating the discharge of the waste inside the pipe when the pipe is cut; when cutting the pipe, under the action of the cooling gas, most of the metal debris can be blown to the left end of the cutting part, while a small amount of debris remains at the right end of the pipe cutting. Moreover, the cooling gas can reduce the temperature of the metal debris and the adhesion between the metal debris and the inner wall of the pipe. At this time, as the mounting seat 2 continues to move to the right, the left end of the pipe (the end with a small amount of metal debris adhered) abuts against the bar 5 and continuously collides with the bar 5 as the mounting seat 2 moves, thereby causing the pipe to vibrate, which is beneficial to the discharge of the metal debris on the inner wall of the pipe.

[0039] When the mounting seat 2 moves to the right to a suitable position, the limit plate 75 at the upper end of the frame 1 first contacts the hemispherical surface arranged inside the outer groove of the spring pin 74, causing the spring pin 74 to move outward and separate from the card slot on the outer side of the slide plate 72, releasing the limit of the slide plate 72 and enabling the rollers 62 to rotate freely; then as the mounting seat 2 continues to move, the limit plate 75 abuts against the lever 721, limiting the maximum moving position of the slide plate 72 through the lever 721. At this time, the slide plate 72 and the chute plate 71 have a relative displacement, driving the transmission gear 621 to rotate through the limit rack 73, and then causing the two rollers 62 to rotate relative to each other, conveying the pipe outward and making the pipe fall on the upper end of the bar 5, realizing the automatic blanking of the cut pipe.

[0040] Finally, the mounting seat 2 resets, and the pipe is conveyed to the right again, making the right end of the pipe abut against the positioning disk 3. At this time, the scraper 31 can scrape off the metal debris adhered to the right side of the inner wall of the pipe (the side with more metal debris adhered), facilitating the subsequent discharge of the debris inside the pipe.

[0041] The implementation principle of a laser cutting machine for bed frame production in an embodiment of this application is as follows: The pipe to be cut is conveyed from left to right through an external feeding mechanism, passing through the first rotating chuck 102 and the second rotating chuck 103 in sequence. At this time, under the driving action of the cylinder 43, the inserting rod 41 slides to the right, causing the pin shaft 411 at the end of the inserting rod 41 to move to the right end of the notch 42, so that the pin shaft 411 and the hinge shaft of the positioning disk 3 are in a horizontally misaligned state, ensuring that the positioning disk 3 and the turntable 21 are in a parallel state. When the pipe is conveyed to abut against the positioning disk 3, it can play a role in positioning the maximum protruding position of the pipe, facilitating the fixed-length cutting of the pipe; at the same time, the scraping knife 31 on the left side of the positioning disk 3 is inserted into the interior of the pipe, which can clean the inner wall of the pipe.

[0042] When the pipe is conveyed to abut against the positioning disk 3, the outer side of the pipe first contacts the roller 62 inside the mounting frame 61. As the pipe is conveyed, the roller 62 rotates under the action of friction. At the same time, the transmission gear 621 outside the roller 62 drives the limit rack 73 and the sliding plate 72 to slide to the right along the chute plate 71 until the end of the pipe abuts against the positioning disk 3. At this time, the end of the spring pin 74 is engaged with the slot on the outer side of the sliding plate 72, thereby limiting the sliding plate 72 and locking the roller 62 through the cooperation of the limit rack 73 and the transmission gear 621, and then clamping and fixing the end of the pipe through the roller 62.

[0043] When the pipe is cut, the mounting frame 61 and the roller 62 can support the tail end of the pipe, preventing the pipe from directly falling when it is cut and improving the accuracy of the cutting part of the pipe; after the pipe is cut, the mounting seat 2 moves to the right, and at the same time the cylinder 43 works, driving the inserting rod 41 to slide to the left, causing the pin shaft 411 at the end of the inserting rod 41 to move to the left end of the notch 42. At this time, the pin shaft 411 and the hinge shaft of the positioning disk 3 are in a coaxial state. At this time, since the right end of the pipe is in a clamped state, under the action of the self-weight of the pipe, the left side of the cut pipe inclines downward and contacts the grid bar 5 inside the frame 1, facilitating the discharge of the waste inside the pipe when the pipe is cut; when the pipe is cut, under the action of the cooling gas, most of the metal chips can be blown to the left end of the cutting part, while a small part of the chips remain at the right end of the pipe cutting. Moreover, the cooling gas can reduce the temperature of the metal chips and the adhesion between the metal chips and the inner wall of the pipe. At this time, as the mounting seat 2 continues to move to the right, the left end of the pipe (the end with a small amount of metal chips adhered) abuts against the grid bar 5 and continuously collides with the grid bar 5 as the mounting seat 2 moves, thereby causing the pipe to vibrate, which is conducive to the discharge of the metal chips on the inner wall of the pipe.

[0044] When the mounting base 2 moves to the right to a proper position, the limiting plate 75 at the upper end of the frame 1 first contacts the hemispherical surface arranged inside the outer groove of the spring pin 74, causing the spring pin 74 to move outward and separate from the card slot on the outer side of the slide plate 72, releasing the limit on the slide plate 72 and enabling the roller 62 to rotate freely; then as the mounting base 2 continues to move, the limiting plate 75 abuts against the lever 721, and the maximum moving position of the slide plate 72 is limited through the lever 721. At this time, a relative displacement occurs between the slide plate 72 and the chute plate 71, and the transmission gear 621 is driven to rotate through the limiting rack 73, thereby causing the two rollers 62 to rotate relatively, conveying the pipe outward, making the pipe fall on the upper end of the grid bar 5, and realizing the automatic blanking of the cut pipe.

[0045] Finally, the mounting base 2 resets, and the pipe is conveyed to the right again, making the right end of the pipe abut against the positioning disk 3. At this time, the scraper 31 can scrape off the metal debris adhered to the right side of the inner wall of the pipe (the side with more adhered metal debris), facilitating the discharge of the internal debris of the pipe in the subsequent process.

[0046] The above is the preferred implementation manner of the present application. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the principle described in the present application, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
