Description

Technical Field

[0001] The invention relates to the technical field of section steel cutting, in particular to a steel structure cutting method. Background Art

[0002] Steel structure construction refers to structural engineering that is mainly made of steel, and is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. These components or parts are usually connected by welds, bolts or rivets, and are one of the main types of building structures.

[0003] Common types of steel used in steel structure construction include I-beams, angle steels, channel steels, etc. The length of steel in steel structure construction is not uniform, and most of them are composed of steels of different lengths to ensure the stability of the steel structure; and shorter I-beams are mostly cut from longer I-beams. Common cutting methods include laser cutting machines, cold chain cutting machines, etc.

[0004] During the cutting process of I-beams by the laser cutting machine, no force is generated to move the I-beams, so the cutting surface after cutting by the laser cutting machine is relatively flat and meets the use requirements; the common cutting process is that the operator first draws positioning lines on the I-beam at equal intervals, and then aligns the positioning lines of the I-beam with the laser cutting machine before performing the cutting action. The whole process is relatively cumbersome. It can complete the cutting process well when a small number of cutting actions are performed, but its production efficiency is not high in the mass production mode. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1 to Figure 11 In an embodiment of the present invention, a steel structure cutting method includes the following steps: Step 1: Remove rust from the surface of the I-beam and clean the stains on the surface of the I-beam; Step 2: Place the cleaned I-beam into the cutting device, and then start the cutting device; Step 3: The cutting device cuts the I-beam; Step 4: Collect the cut I-beams and conduct steel strength tests.

[0031] In another embodiment of the present invention, the cutting device described in step 2 cuts the I-beams at equal intervals to obtain steel structure construction parts of shorter length.

[0032] In another embodiment of the present invention, the cutting device described in step 2 comprises a base 1; and a housing 2 fixedly mounted on the base 1; a laser cutting machine 19 is disposed on the base 1; The base 1 is provided with a walking mechanism, a clamping mechanism and a cutting mechanism that cooperate with each other; The walking mechanism includes a plurality of rollers 903 symmetrically arranged on the base 1; the clamping mechanism includes a clamping plate 13; the cutting mechanism includes an engaging slider 17 fixedly connected to the laser cutting machine 19; When the I-beam is placed on the base 1, the roller 903 is driven to rotate through the walking mechanism to drive the I-beam to move along the length direction of the base 1; and after the I-beam walks to the set length, the clamping mechanism will drive the clamping plate 13 to gradually approach the I-beam to clamp the I-beam; and after the clamping plate 13 is in tight contact with the I-beam, the cutting mechanism can drive the engaging slider 17 to slide along the width direction of the base 1 to drive the laser cutting machine 19 to move synchronously to perform laser cutting on the I-beam.

[0033] Taking the embodiment combining all the features described in the present application as an example, when in use, the I-beam with a cleaned surface is horizontally inserted into the cutting device along the length direction of the base 1; the I-beam and the roller 903 are pressed and collided with each other.

[0034] The roller 903 is driven to rotate by the traveling mechanism, so that the I-beam is driven to move from one end of the base 1 to the other end through the extrusion friction between the roller 903 and the I-beam; a baffle is fixedly installed on the shell 2; the baffle is used to contact one end of the I-beam in the traveling direction to fix the length of the cut I-beam.

[0035] When one end of the I-beam collides with the baffle, the walking mechanism stops moving. At this time, the clamping mechanism will drive the clamping plate 13 to approach the I-beam. When the clamping plate 13 collides with the I-beam, the clamping plate 13 will limit the position of the I-beam to prevent the I-beam from being offset during the cutting process, which will cause the cut I-beam to fail to meet the use requirements.

[0036] When the clamping mechanism completes clamping, the cutting mechanism will drive the engaging slider 17 to move back and forth along the width direction of the base 1, thereby driving the laser cutting machine 19 to move synchronously to cut the I-beam; the cut I-beam will fall to the ground and be collected by the operator; during this process, the clamping mechanism will always keep the I-beam clamped.

[0037] After the cutting mechanism completes the cutting action, the clamping mechanism will drive the clamping plate 13 away from the I-beam to release the clamping state; then the walking mechanism restarts the action to continue to drive the I-beam to move for the next cutting action.

[0038] Through the alternating actions of the traveling mechanism, the clamping mechanism and the cutting mechanism, the longer I-beams can be automatically cut into shorter I-beams at equal intervals, which can effectively improve the cutting efficiency and avoid the cumbersome cutting process caused by repeated positioning, fixing and cutting, thereby improving the production efficiency; since the travel of the traveling mechanism is fixed and assisted by a baffle, the length error between the cut I-beams is small, which meets the actual use requirements.

[0039] In another embodiment of the present invention, a motor 3 is fixedly mounted on the shell 2; a main shaft 4 is fixedly mounted on the output end of the motor 3; an incomplete gear 401 is fixedly mounted on the main shaft 4; three groups of drive shafts 5 are rotatably mounted on the shell 2; the three groups of drive shafts 5 are equidistantly distributed along the circumference of the main shaft 4; a full gear 501 that can mesh with the incomplete gear 401 is fixedly mounted on the drive shaft 5.

[0040] Taking the embodiment of the invention in which all the features are combined as an example, when in use, the motor 3 can reciprocate, thereby driving the main shaft 4 to reciprocate. One driving shaft 5 is connected to the walking mechanism; another driving shaft 5 is connected to the clamping mechanism; and the last driving shaft 5 is connected to the cutting mechanism; When the main shaft 4 rotates forward, it will drive the incomplete gear 401 to rotate synchronously. During the rotation process, the toothed part of the incomplete gear 401 will alternately mesh with the three full gears 501, thereby driving the full gears 501 to rotate alternately; thereby driving the driving shaft 5 to rotate forward; according to the meshing order: the incomplete gear 401 will first drive the driving shaft 5 connected to the walking mechanism to rotate (walking action), and then drive the driving shaft 5 connected to the clamping mechanism to rotate (clamping action), and then drive the driving shaft 5 connected to the cutting mechanism to rotate (cutting action).

[0041] When the main shaft 4 rotates in the opposite direction, it will drive the incomplete gear 401 to rotate synchronously, so as to drive the driving shaft 5 to rotate in the opposite direction through the meshing action, according to the meshing order: first drive the driving shaft 5 connected to the cutting mechanism to rotate in the opposite direction (cutting action), then drive the driving shaft 5 connected to the clamping mechanism to rotate (releasing action), and then drive the driving shaft 5 connected to the traveling mechanism to rotate (the driving shaft 5 and the traveling mechanism are connected by a one-way rotating component, which can only drive the traveling mechanism to move forward. When the driving shaft 5 rotates in the opposite direction, the traveling mechanism does not move).

[0042] Through the alternating actions of the traveling mechanism, the clamping mechanism and the cutting mechanism, the longer I-beams can be automatically cut into shorter I-beams at equal intervals, which can effectively improve the cutting efficiency and avoid the cumbersome cutting process caused by repeated positioning, fixing and cutting, thereby improving the production efficiency; since the travel of the traveling mechanism is fixed and assisted by a baffle, the length error between the cut I-beams is small, which meets the actual use requirements.

[0043] In another embodiment of the present invention, a rotating column 6 is rotatably mounted on the shell 2; a fixed block 7 is fixedly mounted on the driving shaft 5; a thorn groove 601 is opened on the rotating column 6; a plurality of ratchet teeth 701 cooperating with the thorn groove 601 are rotatably mounted on the fixed block 7; and a first pulley 602 is fixedly mounted on the rotating column 6.

[0044] Taking the embodiment combining all the features described in the present application as an example, when in use, a torsion spring for resetting is arranged between the ratchet 701 and the fixing block 7; the ratchet 701 and the thorn groove 601 constitute a one-way transmission component.

[0045] When the driving shaft 5 rotates forward, it will drive the fixed block 7 to rotate synchronously, thereby driving the ratchet 701 to rotate synchronously. Through the extrusion fit between the ratchet 701 and the thorn groove 601, the rotating column 6 will rotate synchronously, thereby driving the first pulley 602 to rotate synchronously, thereby driving the walking mechanism to rotate synchronously.

[0046] When the driving shaft 5 rotates in the reverse direction, the ratchet 701 will be driven to rotate synchronously. At this time, after the rotating ratchet 701 conflicts with the thorn groove 601, the ratchet 701 will rotate to make way, so the rotating column 6 does not rotate, and the first pulley 602 does not rotate, thereby preventing the walking mechanism from rotating in the reverse direction, causing the I-beam to separate from the cutting device.

[0047] In another embodiment of the present invention, the walking mechanism also includes a walking shaft 8 rotatably mounted on the shell 2; a large walking pulley 801 and a second pulley 802 are fixedly mounted on the walking shaft 8; the first pulley 602 and the second pulley 802 are connected by a belt; multiple groups of first shafts 9 fixedly connected to the roller 903 are rotatably mounted on the shell 2; a small walking pulley 901 is fixedly mounted on the first shaft 9; the large walking pulley 801 and the small walking pulley 901 are connected by a belt; a synchronous gear 902 is fixedly mounted on the first shaft 9; and two adjacent synchronous gears 902 are meshed with each other.

[0048] Taking the embodiment combining all the features recorded in the present application as an example, when in use, when the first pulley 602 rotates, the second pulley 802 will be driven to rotate through the belt, thereby driving the travel shaft 8 to rotate, thereby driving the large travel pulley 801 to rotate, and driving the small travel pulley 901 to rotate through the belt, thereby driving the first shaft 9 to rotate.

[0049] The size of the first pulley 602 is larger than that of the second pulley 802, and the size of the large traveling pulley 801 is larger than that of the small traveling pulley 901, so the first rotating shaft 9 can rotate several times.

[0050] The first rotating shafts 9 rotate synchronously through the meshing action of the synchronous gears 902, thereby driving the rollers 903 to rotate synchronously, thereby driving the I-beam to travel a certain distance through the extrusion friction between the I-beam and the rollers 903.

[0051] Since the travel of the traveling mechanism is fixed and assisted by a baffle, the length error between the cut and formed I-beams is small, which meets the actual use requirements.

[0052] In another embodiment of the present invention, the clamping mechanism also includes a clamping shaft 10 rotatably mounted on the shell 2; an engaging groove is provided on the clamping shaft 10; a connecting rod 11 is slidably connected to the clamping shaft 10; the connecting rod 11 is fixedly mounted with a protruding column 1101 slidably engaged with the engaging groove; a guide rod 1102 passing through the shell 2 is fixedly mounted on the connecting rod 11; a push plate 12 connected to the clamping plate 13 is fixedly mounted on the guide rod 1102; the clamping shaft 10 is connected to one of the driving shafts 5 via a belt.

[0053] Taking the embodiment combining all the features recorded in the present application as an example, when in use, when the driving shaft 5 connected to the clamping mechanism rotates, the clamping shaft 10 is driven to rotate through the belt, thereby driving the matching groove to rotate synchronously, thereby driving the protruding column 1101 to slide with the matching groove, thereby driving the connecting rod 11 to move closer to or away from the base 1, so as to drive the push plate 12 to move synchronously through the guide rod 1102, thereby driving the clamping plate 13 to move closer to or away from the I-beam to clamp or release the I-beam.

[0054] By clamping the I-beam with a clamping mechanism, it is possible to prevent the I-beam from being displaced due to external force during the cutting process of the laser cutting machine 19, causing the preset cutting position of the I-beam to be misaligned with the laser cutting machine 19, resulting in the I-beam after cutting not meeting the use requirements.

[0055] In another embodiment of the present invention, the mating groove includes a first flat groove 1001, an inclined groove 1002 and a second flat groove 1003; wherein one end of the first flat groove 1001 is connected to one end of the inclined groove 1002; and the other end of the inclined groove 1002 is connected to one end of the second flat groove 1003.

[0056] Taking the embodiment combining all the features recorded in the present application as an example, when in use, when the clamping shaft 10 rotates in the forward direction, the protruding column 1101 will first slide in the first flat groove 1001, and the position of the connecting rod 11 remains unchanged; then the protruding column 1101 will slide in the inclined groove 1002, and the inclined groove 1002 will squeeze the protruding column 1101, driving the base 1 of the connecting rod 11 to approach, thereby driving the push plate 12 to move synchronously, so as to drive the clamping plate 13 to contact the I-beam to perform a clamping action; finally, the protruding column 1101 will slide in the second flat groove 1003, and the position of the connecting rod 11 remains unchanged, so as to keep the clamping state unchanged.

[0057] When the clamping shaft 10 rotates in the opposite direction, the protruding column 1101 will first slide in the second flat groove 1003, and the position of the connecting rod 11 remains unchanged; then the protruding column 1101 will slide in the inclined groove 1002, and the connecting rod 11 will be driven away from the base 1 through the extrusion effect of the inclined groove 1002 and the protruding column 1101, so as to drive the push plate 12 to move synchronously, thereby driving the clamping plate 13 to separate from the I-beam and gradually move away from the I-beam to release the clamping state, thereby reducing the resistance of the walking mechanism to drive the I-beam to walk, so as to avoid slipping, thereby ensuring that the length error between the cut and formed I-beams is not large; then the protruding column 1101 will slide in the first flat groove 1001, and the connecting rod 11 remains unchanged; and because the first flat groove 1001 limits the protruding column 1101, it can avoid the clamping mechanism from moving toward the I-beam autonomously due to its own weight or other external interference factors, which causes the walking resistance of the walking mechanism to increase, thereby ensuring that the travel of the I-beam driven by the walking mechanism remains relatively uniform.

[0058] In another embodiment of the present invention, a telescopic column 1201 is fixedly installed on the push plate 12; a telescopic sleeve 1301 slidably engaged with the telescopic column 1201 is fixedly installed on the clamping plate 13; a spring 14 is arranged in the telescopic sleeve 1301; and both ends of the spring 14 respectively contact the telescopic column 1201 and the clamping plate 13.

[0059] Taking the embodiment combining all the features recorded in the present application as an example, when in use, when the connecting rod 11 approaches the base 1, it will drive the push plate 12 to move synchronously, thereby driving the clamping plate 13 to collide with the I-beam, and after the collision, the push plate 12 drives the telescopic column 1201 to slide inward in the telescopic sleeve 1301, compressing the spring 14, and the elastic force of the spring 14 acts on the clamping plate 13 to clamp the I-beam, and can avoid the squeezing force between the clamping plate 13 and the I-beam to cause structural damage to the clamping mechanism, thereby increasing the service life of the device.

[0060] When the connecting rod 11 moves away from the base 1, the push plate 12 will drive the telescopic column 1201 to slide outward in the telescopic sleeve 1301, and the compression of the spring 14 will gradually decrease; when the telescopic column 1201 slides to the maximum stroke, it will drive the telescopic sleeve 1301 to move synchronously, so that the clamping plate 13 is separated from the I-beam, and the release action is completed, thereby reducing the resistance of the walking mechanism to drive the I-beam to move.

[0061] In another embodiment of the present invention, the cutting mechanism includes a cutting shaft 15 rotating on the shell 2; the cutting shaft 15 is connected to one of the driving shafts 5 by a belt; a rotating rod 16 is fixedly installed on the cutting shaft 15; a protruding column 1601 is fixedly installed on the rotating rod 16; a guide rail 201 slidably engaged with the engaging slider 17 is fixedly installed on the shell 2; a connecting plate 18 is fixedly installed on the engaging slider 17; a sliding groove 1801 slidably engaged with the protruding column 1601 is provided on the connecting plate 18.

[0062] Taking the embodiment combining all the features recorded in the present application as an example, when in use, when the driving shaft 5 connected to the cutting mechanism rotates, the driving shaft 5 will drive the cutting shaft 15 to rotate through the belt, thereby driving the rotating rod 16 to rotate, thereby driving the raised column 1601 to rotate, and through the extrusion fit between the raised column 1601 and the connecting plate 18, the connecting plate 18 is driven to slide, thereby driving the embedded slider 17 to slide on the guide rail 201, thereby driving the laser cutting machine 19 to translate, and during the translation process, the I-beam is cut.

[0063] When the driving shaft 5 rotates in the reverse direction, the engaging slider 17 is driven to slide in the reverse direction on the guide rail 201, thereby driving the laser cutting machine 19 to translate in the reverse direction to cut the I-beam again to prevent adhesion caused by the first cutting action.

[0064] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
