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. 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 existing technology, 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 publication number CN118455782B, which is titled as a pipe laser cutting device, the device includes a cutting table, multiple support components and a shielding rod. The support component can support the cut pipe, so that the shielding rod can be suspended inside the pipe, thereby protecting the inner wall of the pipe and reducing the probability of metal chips adhering to the inner wall of the pipe.

[0005] With reference to the above technical solution, the tail end of the pipe is supported by a support 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 smaller diameters and longer lengths, such as the square beams of the bed frame, the shielding rod is more difficult to install during use, and during subsequent cutting, the shielding rod needs to be pulled out from the inside of the pipe, which requires a larger operating space and makes 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. However, when cutting the square beam of the bed frame, due to its small diameter and long length, the cooling gas is difficult to blow the molten metal and slag out of the pipe. Instead, it will blow the molten metal and slag deeper into the pipe, making it more troublesome to clean the metal chips inside the pipe later, 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 debris adhering to the inner wall of the pipe after cutting the cross beam of the bed frame, thus affecting the production efficiency and quality of the bed frame.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the Figures 1-8 of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present application fall within the scope of protection of the present application.

[0038] Refer 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 component 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.

[0039] Refer to Figure 1 and Figure 2, the adjusting mechanism includes a mounting base 2, a turntable 21, a positioning disk 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 disk 3 is hinged to the left side of the turntable 21. The positioning disk 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 disk 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 disk 3. The pin shaft 411 is located inside the corresponding notch 42 on the same side.

[0040] [[ID=e3]]Refer to Figure 3 and Figure 4 , a gas ring 32 is rotatably connected to the middle of the positioning disk 3. The gas ring 32 is communicated with the air hole 33 in the middle of the positioning disk 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.

[0041] The pipe to be cut is conveyed from left to right by 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 disk 3 are in a horizontally misaligned state, which can ensure 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 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 disk 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 subsequent injecting 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 subsequent cleaning of the metal chips adhered to the inner wall of the pipe.

[0042] Refer to Figure 5 , Figure 6 and Figure 7The clamping assembly 6 includes a mounting bracket 61, an adjusting bolt 63 and a locking unit 7. The mounting bracket 61 is slidably connected to the left side of the positioning plate 3. There are two mounting brackets 61. The interiors of the two mounting brackets 61 are rotatably connected to rollers 62. The adjusting bolts 63 are rotatably connected to the interiors of the mounting brackets 61. The adjusting bolts 63 are respectively threadedly connected to the corresponding screw holes at the edge of the positioning plate 3. The adjusting bolts 63 are used to adjust the positions of the mounting bracket 61 and the roller 62 so that the roller 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 gear 621 arranged at the end of the rotating shaft of the roller 62 to lock the roller 62, so that the tube is clamped and fixed by the roller 62; the locking unit 7 includes a slide plate 71, a slide plate 72, a limit rack 73 and a spring pin 74. The slide plate 71 is arranged at the left edge of the positioning disk 3, the slide plate 72 is slidably connected to the inside of the slide plate 71, and the limit rack 73 is adjustably mounted on the slide plate 7 by bolts. 2, there are two limiting racks 73, which are respectively engaged with the transmission gear 621 corresponding to the end of the roller 62, and the spring pin 74 is arranged inside the slide plate 71. The outer side of the slide plate 72 is provided with a card slot that cooperates with the spring pin 74, and the middle part of the slide plate 72 is provided with a shift rod 721, which is located in the limiting groove 711 provided in the middle of the slide plate 71. The upper end of the frame 1 is provided with a limiting plate 75 corresponding to the positions of the spring pin 74 and the shift rod 721.

[0043] When the pipe is transported to abut against the positioning disk 3, the outer side surface of the pipe first contacts the roller 62 inside the mounting frame 61. As the pipe is transported, the roller 62 rotates under the action of friction. At the same time, the transmission gear 621 on the outside of the roller 62 drives the limiting rack 73 and the slide plate 72 to slide to the right along the slide plate 71 until the end of the pipe abuts against the positioning disk 3. At this time, the end of the spring pin 74 engages with the slot on the outer side of the slide plate 72, thereby limiting the slide plate 72 and locking the roller 62 through the cooperation of the limiting rack 73 and the transmission gear 621, thereby clamping and fixing the end of the pipe through the roller 62.

[0044] Reference Figure 1 and Figure 3 A first motor 8 is provided in the middle of the mounting base 2. The first motor 8 can drive the turntable 21 to rotate through gear transmission, drive the pipe to rotate, and facilitate the cutting of the pipe; a second motor 9 is provided at the upper end of the mounting base 2. The second motor 9 can drive the mounting base 2 to slide left and right through the cooperation of gears and racks.

[0045] Reference Figure 1 and Figure 2, inside the frame 1, grating bars 5 are arranged in a left-right array. The grating bars 5 are made of aluminum, which can protect against the collision of the pipe. The grating 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 grating bars 5 is provided for collecting the debris discharged from the inside of the pipe.

[0046] When the pipe is being cut, 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. 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 grating bars 5 inside the frame 1 (refer to Figure 8 ), facilitating the discharge of the waste inside the pipe when the pipe is cut; when the pipe is being cut, 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 grating bars 5 and continuously collides with the grating bars 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.

[0047] When the mounting seat 2 moves to the right to a suitable position, the limiting plate 75 at the upper end of the frame 1 first contacts the hemispherical surface arranged inside the groove on the outer side of the spring pin 74, causing the spring pin 74 to move outward and separate from the clamping groove 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 limiting 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 undergo relative displacement, driving the transmission gear 621 to rotate through the limiting rack 73, and then causing the two rollers 62 to rotate relatively, conveying the pipe outward and making the pipe fall on the upper end of the grating bars 5, realizing the automatic blanking of the cut pipe.

[0048] 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.

[0049] The implementation principle of a laser cutting machine for bed frame production in an embodiment of the present application is as follows: The pipe to be cut is conveyed from left to right through an external feeding mechanism, so that the pipe sequentially passes through the first rotating chuck 102 and the second rotating chuck 103. At this time, under the driving action of the cylinder 43, the insertion rod 41 slides to the right, so that the pin shaft 411 at the end of the insertion rod 41 moves to the right end of the notch 42, and the pin shaft 411 of the insertion rod 41 is horizontally misaligned with the hinge shaft of the positioning disk 3, which can ensure 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 extended 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.

[0050] 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 slide 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 slide plate 72, thereby limiting the slide 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.

[0051] 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 insertion rod 41 to slide to the left, so that the pin shaft 411 at the end of the insertion rod 41 moves to the left end of the notch 42. At this time, the pin shaft 411 of the insertion rod 41 is in a coaxial state with the hinge shaft of the positioning disk 3. 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 tilts 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 reduce 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 beneficial to the discharge of the metal chips on the inner wall of the pipe.

[0052] When the mounting base 2 moves to the right to an appropriate 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 outwards and separate from the card slot on the outer side of the sliding plate 72, releasing the limit of the sliding 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 sliding plate 72 is limited through the lever 721. At this time, relative displacement occurs between the sliding plate 72 and the chute plate 71, and the driving gear 621 is rotated through the limiting rack 73, thereby causing the two rollers 62 to rotate relatively, conveying the pipe outwards, making the pipe fall on the upper end of the grid bar 5, and realizing the automatic blanking of the cut pipe.

[0053] 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.

[0054] The above is the preferred embodiment of the present application. It should be noted that for those of ordinary skill in the art in this 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.
