Description

Technical Field

[0001] The invention relates to the technical field of plate shearing machines, in particular to a plate shearing method for processing steel structures. Background Art

[0002] Shearing is required for steel structures primarily to meet the requirements of steel structure projects for plate cutting to length, hole processing, and precise and efficient processing of metal materials. Specifically, in steel structure projects, steel plates often need to be cut to length according to specific design requirements. Shearing equipment can accurately cut steel plates to the required length and width, ensuring that the steel plate dimensions meet project requirements and facilitate subsequent assembly and welding. Through precise shearing, the steel plate material can be maximized and waste can be reduced. At the same time, high-quality shearing ensures that the cut surface of the steel plate is smooth and burr-free, improving the overall quality and aesthetics of the product.

[0003] The shearing methods used in steel structure processing mainly include the following: 1. Manual shearing, which uses a manual shearing machine to cut the steel plate. However, this method easily causes the steel plate to curl during the shearing process and the cutting edge quality is poor, so it is not widely used now; 2. Mechanical shearing, which uses mechanical equipment such as shearing machines for shearing; 3. Cutting wheel cutting, which uses a high-speed rotating cutting wheel to cut steel; 4. Laser cutting, which uses the heat of a laser beam to cut steel plates; 5. Plasma arc cutting.

[0004] However, although laser cutting and plasma arc cutting can cut steel structures quickly and effectively, and the cut surface is smooth and burr-free, both are local thermal cutting. The molten steel accumulates at the incision and easily forms material nodules after cooling. Although manual shearing and mechanical shearing are low in cost, the resistance to deep cutting of the tool is large, which can easily cause the steel plate to curl and the cutting edge quality to be poor. At the same time, the blade is also easily damaged. Frequent replacement of blades not only wastes time and reduces production efficiency, but also increases costs. In summary, the method of cutting with a cutting wheel is a better choice. However, when using a cutting wheel to cut steel structures, the cutting quality not only depends on the quality of the cutting wheel, but also whether the steel structure can be stably clamped. Because when the tool is deeply shearing, the tool is similar to being embedded in the steel. Therefore, it is necessary not only to ensure that the material is stable during the cutting process, but also to ensure that the tool has a large instantaneous shear force when performing deep shearing.

The running cutting device will fix and cut the steel structure. During the cutting process, it is necessary to keep an eye on it to prevent deviations, accidents, etc. Step 4: Correction and adjustment.

[0035] See also Figure 1 In an embodiment of the present invention, a shearing method for steel structure processing includes the following steps: Step 1: Material inspection: carefully inspect the steel structure materials to ensure that the materials are free of cracks, rust and other defects, and meet the design requirements; Step 2: Equipment inspection and preparation: Place the steel structure to be processed on the cutting device, and then adjust and set the cutting device; Step 3: Shear the plate and start the cutting device. The running cutting device will fix and cut the steel structure. During the cutting process, it is necessary to keep an eye on it to prevent deviations, accidents, etc. Step 4: Correction and adjustment. After the cutting is completed, it is necessary to check whether the quality and size of the cut surface meet the requirements. If there are any problems, adjustments and corrections need to be made in time to ensure the quality and performance of the final product.

[0036] See also Figures 2 to 14 The cutting device in step 2 includes a machine tool 1 and a frame 2 fixedly provided on the machine tool 1, a guide rod 3 is fixedly provided on the frame 2 horizontally, a movable frame 4 is slidably provided on the guide rod 3, and a cutting wheel 6 is rotatably provided on the movable frame 4 via a rotating shaft 5; The frame 2 is provided with a reciprocating assembly, which is connected to the mobile frame 4. When the reciprocating assembly is running, the mobile frame 4 will drive the cutting wheel 6 to move horizontally back and forth. The frame 2 is provided with a rotating assembly, which cooperates with the mobile frame 4 and the rotating shaft 5 respectively, and is connected to the reciprocating assembly through a speed-increasing transmission structure. During the operation of the reciprocating assembly, the rotating assembly will drive the cutting wheel 6 to rotate rapidly under the drive of the speed-increasing transmission structure; The machine tool 1 is provided with an elastic pressing component, which can pressurize and fix the steel on the machine tool 1 when the elastic pressing component is in operation; The machine tool 1 is provided with a driving mechanism connected to the elastic pressing assembly, and the driving mechanism is connected to the reciprocating assembly through a synchronization structure. When the driving mechanism is running, the elastic pressing assembly and the reciprocating assembly will perform alternating actions.

[0037] In this solution, the driving mechanism and synchronization structure set up can drive the elastic clamping component and the reciprocating component to perform alternating movements. When the elastic clamping component is running, it can apply pressure to fix the steel on the machine tool 1 to prevent the steel from shifting during the cutting process, thereby affecting the cutting quality. When the reciprocating component is running, it can not only drive the cutting wheel 6 to move horizontally through the movable frame 4, but also the rotating component will cooperate with the reciprocating component through the speed-increasing transmission structure to make the cutting wheel 6 rotate at high speed. The high-speed rotating cutting wheel 6 cuts deeply and cooperates with its horizontal movement, thereby cutting the steel fixed on the machine tool 1 by the elastic clamping component.

[0038] See also Figure 4 、 Figure 5 The reciprocating assembly includes a first rotating column 7 and a second rotating column 8 respectively rotatably arranged on the frame 2, and a first sprocket 9 and a second sprocket 10 are fixedly provided at one end of the first rotating column 7 and the second rotating column 8 respectively, and the first sprocket 9 and the second sprocket 10 are connected by a chain 11; A slide 12 is rotatably provided on one of the links of the chain 11 , and a slide groove 401 is vertically opened on one side of the movable frame 4 close to the chain 11 . The slide 12 is located in the slide groove 401 and slides with each other.

[0039] In this embodiment, since the first sprocket 9 fixed to the first rotating post 7 and the second sprocket 10 fixed to the second rotating post 8 are connected by a chain 11, when the first rotating post 7 rotates, the first sprocket 9, the chain 11, the second sprocket 10 and the second rotating post 8 will rotate synchronously; Because the slide 12 rotatably arranged on one of the links of the chain 11 is located in the slide groove 401 provided on the movable frame 4 and slides with each other, and the movable frame 4 is slidably arranged on the guide rod 3, during the rotation of the chain 11, the movable frame 4 will move back and forth horizontally, thereby driving the rotating shaft 5 and the cutting wheel 6 to move back and forth horizontally after penetrating into the steel, and perform deep cutting.

[0040] See also Figure 7 、 Figure 11 、 Figure 14 The rotating assembly includes a rotating rod 13 rotatably provided on the frame body 2 and a sleeve 14 rotatably provided on the mobile frame 4 , and the sleeve 14 is movably sleeved on the outer wall of the rotating rod 13 ; The outer wall of the rotating rod 13 is fixedly provided with a protrusion 1301 along its length direction, and the inner wall of the sleeve 14 is provided with a groove 1401, and the protrusion 1301 is located in the groove 1401 and slides with each other; The rotating assembly further includes a first bevel gear 15 fixedly mounted on the sleeve 14 and a second bevel gear 16 fixedly mounted on the rotating shaft 5. A transmission rod 17 is vertically rotated on the movable frame 4. A third bevel gear 18 and a fourth bevel gear 19 are fixedly provided at both ends of the transmission rod 17 , respectively. The third bevel gear 18 and the first bevel gear 15 are meshed with each other, and the fourth bevel gear 19 and the second bevel gear 16 are meshed with each other.

[0041] In this embodiment, the sleeve 14 is movably mounted on the outer wall of the rotating rod 13, and the protrusion 1301 fixed on the outer wall of the rotating rod 13 is located in the groove 1401 provided on the inner wall of the sleeve 14 and slides with each other. Therefore, when the rotating rod 13 rotates, the sleeve 14 will also rotate accordingly, and the sleeve 14 can also slide horizontally on the outer wall of the rotating rod 13, thereby not interfering with the horizontal reciprocating movement of the movable frame 4. Because the fourth bevel gear 19 fixed on the transmission rod 17 and the second bevel gear 16 fixed on the rotating shaft 5 are meshed with each other, when the transmission rod 17 rotates at high speed, the rotating shaft 5 will rotate accordingly, thereby driving the cutting wheel 6 to rotate at high speed, ensuring that the cutting wheel 6 can have a large deep shear force during the movement; Since the third bevel gear 18 fixed on the transmission rod 17 and the first bevel gear 15 fixed on the sleeve 14 are engaged with each other, when the sleeve 14 rotates at a high speed, the transmission rod 17 will rotate with the high speed.

[0042] See also Figure 7 、 Figure 11 The speed increasing transmission structure includes a No. 3 rotating column 20 rotatably arranged on the frame 2 and a No. 5 bevel gear 21 fixedly arranged at one end of the rotating rod 13. The two ends of the No. 3 rotating column 20 are respectively fixedly provided with a No. 6 bevel gear 22 and a No. 1 transmission wheel 23; The sixth bevel gear 22 and the fifth bevel gear 21 are meshed with each other. A second transmission wheel 24 is fixedly provided at the other end of the second rotating column 8 . The second transmission wheel 24 is connected to the first transmission wheel 23 via a first belt 25 .

[0043] In this embodiment, since the sixth bevel gear 22 fixed on the third rotating column 20 and the fifth bevel gear 21 fixed on one end of the rotating rod 13 are engaged with each other, when the third rotating column 20 rotates at high speed, the rotating rod 13 will follow the high-speed rotation, thereby driving the sleeve 14 to rotate at high speed; Because the second transmission wheel 24 fixed at the other end of the second rotating column 8 and the first transmission wheel 23 fixed on the third rotating column 20 are connected by the first belt 25, when the second rotating column 8 rotates, the third rotating column 20 will rotate accordingly; The diameter of the second transmission wheel 24 is greater than the diameter of the first transmission wheel 23 , so the third rotating column 20 will rotate at a high speed, thereby achieving the function of increasing the speed.

[0044] See also Figure 9 、 Figure 10 The elastic pressing assembly includes a limit rod 26 fixed vertically on the machine tool 1 and a horizontal plate 27 with one end slidingly engaged with the limit rod 26. A screw rod 28 is vertically rotatably provided on the machine tool 1, and the other end of the horizontal plate 27 is threadedly engaged with the screw rod 28. A number seven bevel gear 29 is fixedly provided at the bottom end of the screw rod 28, and a clamping seat 30 is vertically slidably provided on the horizontal plate 27. A spring 31 is sleeved on the outer wall of the clamping seat 30, and the two ends of the spring 31 are respectively abutted against the clamping seat 30 and the horizontal plate 27, so that the clamping seat 30 always has a tendency to move toward the machine tool 1.

[0045] In this embodiment, one end of the cross plate 27 is in sliding engagement with the limiting rod 26 fixed to the machine tool 1, and the other end of the cross plate 27 is in threaded engagement with the screw rod 28. Therefore, when the seventh bevel gear 29 drives the screw rod 28 to rotate, the cross plate 27 will move closer to the machine tool 1. Because a clamping seat 30 is vertically slidably provided on the horizontal plate 27, and the spring 31 makes the clamping seat 30 always have a tendency to move toward the machine tool 1, therefore, in the process of the horizontal plate 27 approaching the machine tool 1, the clamping seat 30 will press the steel. During this process, the spring 31 will be further compressed. Due to the presence of the spring 31, the clamping seat 30 and the steel are in elastic contact, thereby avoiding damage to the equipment and the steel.

[0046] See also Figure 12 、 Figure 13 The driving mechanism includes a No. 1 driving rod 32 and a No. 2 driving rod 33 which are respectively rotatably arranged on the machine tool 1, and a slide plate 34 is provided on the outer wall sliding sleeve of the No. 1 driving rod 32 and the No. 2 driving rod 33; An electric push rod 35 is fixedly provided on the machine tool 1 , and an output end of the electric push rod 35 is fixedly connected to one side of the slide 34 . An end of the No. 1 driving rod 32 is fixedly provided with a No. 8 bevel gear 38 that meshes with the No. 7 bevel gear 29 .

[0047] In this embodiment, since the slide plate 34 is slidably arranged on the outer wall of the No. 1 drive rod 32 and the No. 2 drive rod 33, and the output end of the electric push rod 35 is fixedly connected to one side of the slide plate 34, when the output end of the electric push rod 35 is retracted, the slide plate 34 will slide on the outer wall of the No. 1 drive rod 32 and the No. 2 drive rod 33; Because one end of the No. 1 driving rod 32 is fixedly provided with the No. 8 bevel gear 38 that meshes with the No. 7 bevel gear 29, when the No. 1 driving rod 32 rotates, the No. 8 bevel gear 38 will drive the No. 7 bevel gear 29 to rotate, thereby causing the screw rod 28 to rotate.

[0048] See also Figure 13 The outer wall of the No. 1 driving rod 32 is provided with a No. 1 spiral groove 3201 and a No. 1 straight groove 3202 along its length direction, and the No. 1 spiral groove 3201 and the No. 1 straight groove 3202 are connected; The outer wall of the second driving rod 33 is provided with a second straight groove 3301 and a second spiral groove 3302 along its length direction, and the second straight groove 3301 and the second spiral groove 3302 are connected; The two ends of the slide plate 34 are respectively rollingly engaged with a first ball 36 and a second ball 37. The first ball 36 is also rollingly engaged in the first spiral groove 3201, and the second ball 37 is also rollingly engaged in the second straight groove 3301. Among them, the length of the No. 1 spiral groove 3201 along the length direction of the No. 1 driving rod 32 is equal to the length of the No. 2 straight groove 3301 and the position corresponds, and the length of the No. 2 spiral groove 3302 along the length direction of the No. 2 driving rod 33 is equal to the length of the No. 1 straight groove 3202 and the position corresponds.

[0049] In this embodiment, since the first and second balls 36 and 37 are respectively rollingly engaged at both ends of the slide plate 34, the first ball 36 is also rollingly engaged in the first spiral groove 3201, and the second ball 37 is also rollingly engaged in the second straight groove 3301, when the slide plate 34 drives the first and second balls 36 and 37 to move, the first drive rod 32 will rotate, while the second drive rod 33 will remain stationary. Because the length of the No. 1 spiral groove 3201 along the length direction of the No. 1 drive rod 32 is equal to the length of the No. 2 straight groove 3301 and the positions correspond, and the length of the No. 2 spiral groove 3302 along the length direction of the No. 2 drive rod 33 is equal to the length of the No. 1 straight groove 3202 and the positions correspond, therefore, when the No. 1 ball 36 enters the No. 1 straight groove 3202 from the No. 1 spiral groove 3201, the No. 2 ball 37 will also enter the No. 2 spiral groove 3302 from the No. 2 straight groove 3301. At this time, when the slide 34 continues to move, the No. 2 drive rod 33 will rotate and the No. 1 drive rod 32 will remain stationary.

[0050] See also Figure 4 、 Figure 11 、 Figure 12 The synchronization structure includes a third transmission wheel 39 fixedly set on the second driving rod 33, and a fourth transmission wheel 40 is fixedly set on the other end of the first rotating column 7. The third transmission wheel 39 and the fourth transmission wheel 40 are connected by a second belt 41.

[0051] In this embodiment, since the third transmission wheel 39 fixed to the second driving rod 33 and the fourth transmission wheel 40 fixed to the other end of the first rotating post 7 are connected by the second belt 41, when the second driving rod 33 rotates, the first rotating post 7 will rotate accordingly.
