Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and more particularly to a cutting device for steel structure steel materials. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. The raw materials of steel structure need to be cut before use during production and processing.

[0003] At present, some cutting devices require workers to push the steel. Since there is no limit on the steel, the steel is easily offset during the pushing process, causing damage to the steel. This is time-consuming and labor-intensive, and can easily cause certain dangers to the workers.

[0004] The Chinese patent with authorization announcement number: CN218693290U discloses a cutting device. Through the coordinated use of a first threaded rod, a first motor, a threaded block, a connecting block, a push plate, a limit plate, a vertical plate, and a second threaded rod, the steel can be pushed forward by the movement of the push plate, avoiding manual pushing by the staff, reducing the work intensity, and improving the work efficiency. At the same time, through the limiting of two sets of limit plates, the steel is prevented from being offset during the cutting process, thereby causing damage to the steel. Through the coordinated use of a fixing plate, a second hydraulic rod, a pressing plate, and a spring, the steel can be fixed, and the spring is set to provide a buffering effect on it.

[0005] Although the above patent can improve work efficiency and cutting effect, it has certain limitations. In the process of advancing the steel pipe, it is necessary to manually rotate the second threaded rod, which is cumbersome. At the same time, the first motor is required to drive the pushing plate to move back and forth. In the process of fixing the steel pipe, it is necessary to operate the fixing mechanism to fix it. After the cutting is completed, the fixing mechanism needs to be operated again to contact and fix it. As a result, a lot of time needs to be spent on advancing and fixing the steel pipe, which seriously affects the cutting efficiency. Summary of the invention

[0018] Furthermore, a mounting groove connected to the vertical groove is provided on the side wall of the collection box, a sealing rod is slidably installed in the mounting groove, a connecting port connected to the vertical groove is provided on the sealing rod, and a second spring is fixedly installed between the sealing rod and the mounting groove.

[0019] Furthermore, the bottom wall of the groove forms an angle of sixty degrees with the horizontal plane.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) This solution sets an elastic airbag, which drives the second connecting pipe to gradually contact the air groove during the upward movement of the connecting rod. When the connecting rod is completely retracted into the sliding groove, the second connecting pipe contacts the air groove. At this time, the elastic airbag sucks air from the arc groove through the second connecting pipe, the air groove, and the first air pipe, and creates a negative pressure in the arc groove. Then, under the action of pressure, the arc groove sucks air through the air hole. At this time, the steel pipe fits tightly with the air hole, and then the steel pipe and the arc plate are sucked together under the action of pressure. Since the surface of the steel pipe is an arc surface, the arc plate and the steel pipe are sucked together, which can prevent the steel pipe from rotating during the cutting process to affect the cutting effect, thereby improving the cutting effect.

[0022] (2) In this solution, the arc plate is driven by the gas cylinder and the piston rod to gradually contact the steel pipe and exert pressure on the steel pipe during the downward movement of the mounting plate. Since the bottom wall of the arc plate is an arc surface, the steel pipe gradually moves toward the middle under the combined action of pressure and the arc surface, which means that the user does not need to spend a lot of time to straighten the steel pipe. At the same time, although the piston rod moves upward along the inner wall of the gas cylinder and squeezes the first spring during the downward movement of the gas cylinder, the arc plate is driven by the piston rod to clamp and fix the steel pipe under the action of the elastic force of the first spring, thereby improving the cutting efficiency.

[0023] (3) In this scheme, the first connecting pipe is provided. When the connecting rod moves upward, the gas between the top wall of the connecting rod and the slide groove is squeezed and blown toward the steel pipe through the first connecting pipe, the gas groove, the first gas pipe, the arc groove, and the gas hole. Then, under the action of the gas, the debris remaining on the surface of the steel pipe is separated from the steel pipe. Then, when the connecting rod moves upward, the first connecting pipe is gradually separated from the gas groove. When the first connecting pipe is separated from the gas groove, the second connecting pipe is in contact with the gas groove, which ensures that the steel pipe and the arc plate can be sucked together.

[0024] (4) In this solution, a brush plate is provided. When the piston rod moves upward along the air cylinder, the air flow in the air cylinder is driven to flow into the installation cylinder through the second air pipe. Then, under the action of the air flow, the push rod drives the brush plate to move downward. When the brush plate moves downward, the bristles are driven to move and clean the debris on the surface of the filter screen, thereby effectively preventing the filter screen from being blocked by debris, thereby ensuring the normal operation of the filter screen.

[0025] (5) This solution drives the impact rod to rotate during the rotation of the rotating rod through the cooperation between the impact rod and the inclined block. During the rotation of the rotating rod, the impact rod gradually contacts the inclined surface of the inclined block and applies thrust to the inclined block. Then, under the action of the thrust, the inclined block drives the filter to move and stretch the elastic pad. When the impact rod is out of contact with the inclined block, the elastic pad contracts and drives the filter to reset. That is, during the rotation of the rotating rod, the filter can be driven to shake back and forth. During the shaking of the filter back and forth, the debris on the filter can be loosened, which makes it easier for the brush to clean the debris on the filter, thereby achieving a cleaning effect.

[0026] (6) This scheme opens a cavity. During the extension of the elastic pad, the cavity draws air from the outside through the air inlet valve. During the contraction of the elastic pad, the gas in the cavity flows into the elastic membrane through the exhaust valve and the horizontal tube, causing the elastic membrane to expand. Then, during the downward movement of the brush plate, the gas gradually contacts the sealing rod and applies a thrust to the inclined surface on the sealing rod. Under the action of the thrust, the sealing rod moves into the mounting groove and squeezes the second spring. During the movement of the sealing rod, the connecting port is driven to move. When the side wall of the brush plate fits with the collecting port, the connecting port contacts the vertical groove. At this time, the gas in the elastic membrane is blown toward the bristles through the horizontal tube, the vertical groove, the horizontal groove, and the groove, causing the debris adhering to the bristles to break away from the bristles, thereby improving the cleaning effect of the bristles.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 8 , a cutting device for steel structure steel, comprising a workbench 1;

[0039] The cutting machine 7 includes a first conveyor belt 2 and a second conveyor belt 3 rotatably mounted on a workbench 1. A mounting frame 4 is fixedly mounted on the top wall of the workbench 1. An electric telescopic rod 5 is fixedly mounted on the top wall of the mounting frame 4. A mounting plate 6 is fixedly mounted on the output end of the electric telescopic rod 5. A cutting machine 7 is fixedly mounted on the bottom wall of the mounting plate 6. A cutting disc 8 is fixedly mounted on the output end of the cutting machine 7. After the first conveyor belt 2 transports the steel pipe to the bottom of the cutting disc 8, the steel pipe is cut by the cutting disc 8.

[0040] Fixing mechanism: An air cylinder 9 is fixedly installed on the bottom wall of the mounting plate 6, a piston rod 10 is slidably installed in the air cylinder 9, a first spring 11 is fixedly installed between the top wall of the piston rod 10 and the air cylinder 9, an arc plate 12 is fixedly installed on the bottom wall of the piston rod 10, and during the downward movement of the mounting plate 6, the arc plate 12 gradually contacts with the steel pipe to align and fix the steel pipe.

[0041] An arc-shaped groove 13 is provided on the arc plate 12, and air holes are evenly provided on the bottom wall of the arc-shaped groove 13. An air groove 14 is provided on the piston rod 10, and a first air pipe 15 connected to the arc-shaped groove 13 is inserted on the bottom wall of the air groove 14. A slide groove 16 connected to the air groove 14 is provided on the piston rod 10, and a connecting rod 17 is slidably installed in the slide groove 16. A first connecting pipe 18 connected to the air groove 14 is inserted on the top wall of the connecting rod 17.

[0042] An elastic airbag 19 is fixedly installed between the linkage rod 17 and the slide groove 16 . A second connecting pipe 20 communicating with the air groove 14 is inserted into the elastic airbag 19 . A one-way valve 21 communicating with the outside is inserted into the elastic airbag 19 .

[0043] When in use, place the steel pipe on the top wall of the first conveyor belt 2, then start the first conveyor belt 2 and the second conveyor belt 3, and convey the steel pipe to the bottom of the cutting disc 8 during the operation of the first conveyor belt 2. Then the user can close the first conveyor belt 2 and the second conveyor belt 3 and start the electric telescopic rod 5. Then the output end of the electric telescopic rod 5 drives the cutting disc 8 to contact the steel pipe through the mounting plate 6 and the cutting machine 7. At this time, the user can start the cutting machine 7 and drive the cutting disc 8 to cut the steel pipe. At the same time, during the downward movement of the mounting plate 6, the air The cylinder 9 and the piston rod 10 drive the arc plate 12 to gradually contact the steel pipe and apply pressure to the steel pipe. Since the bottom wall of the arc plate 12 is an arc surface, the steel pipe gradually moves to the middle under the combined action of pressure and the arc surface, that is, the user does not need to spend a lot of time to straighten the steel pipe. At the same time, although the piston rod 10 moves upward along the inner wall of the cylinder 9 and squeezes the first spring 11 during the downward movement of the cylinder 9, at this time, under the action of the elastic force of the first spring 11, the piston rod 10 drives the arc plate 12 to clamp and fix the steel pipe, which improves the cutting efficiency.

[0044] In the process of the arc plate 12 moving downward, the connecting rod 17 is driven to gradually contact with the steel pipe and exert a thrust on the steel pipe. Then, under the action of the thrust reaction force, the connecting rod 17 slides upward along the slide groove 16. In the process of the connecting rod 17 moving upward, the elastic airbag 19 is stretched and has a tendency to inhale air through the second connecting pipe 20. In the process of the connecting rod 17 moving upward, the second connecting pipe 20 is driven to gradually contact with the air groove 14. When the connecting rod 17 is completely retracted into the slide groove 16, the second connecting pipe 20 and the air groove 14 are separated. At this time, the elastic airbag 19 draws air from the arc groove 13 through the second connecting pipe 20, the air groove 14, and the first air pipe 15, and makes the arc groove 13 have negative pressure. Then, under the action of pressure, the arc groove 13 draws air through the air holes. Since the steel pipe is tightly fitted with the air holes at this time, the steel pipe and the arc plate 12 are sucked together under the action of pressure. Since the surface of the steel pipe is an arc surface, by sucking the arc plate 12 and the steel pipe together, the steel pipe can be prevented from rotating during the cutting process to affect the cutting effect, thereby improving the cutting effect.

[0045] During the upward movement of the connecting rod 17, the gas between the top wall of the connecting rod 17 and the slide groove 16 is squeezed and blown toward the steel pipe through the first connecting pipe 18, the air groove 14, the first air pipe 15, the arc groove 13, and the air hole. Then, under the action of the gas, the debris remaining on the surface of the steel pipe is separated from the steel pipe. Then, during the upward movement of the connecting rod 17, the first connecting pipe 18 is gradually separated from the air groove 14. When the first connecting pipe 18 is separated from the air groove 14, the second connecting pipe 20 is in contact with the air groove 14, which ensures that the steel pipe and the arc plate 12 can be sucked together.

[0046] When the cutting is completed, the output end of the electric telescopic rod 5 contracts and drives the mounting plate 6 to move upward. In the process of the mounting plate 6 moving upward, the air cylinder 9 and the piston rod 10 are driven to move upward. In the process of the piston rod 10 moving upward, the elastic airbag 19 contracts and drives the linkage rod 17 to move downward and reset. In the process of the linkage rod 17 moving downward, the second connecting pipe 20 is driven to break contact with the air groove 14. At this time, the gas in the elastic airbag 19 flows to the outside through the one-way valve 21. At the same time, in the process of the second connecting pipe 20 breaking contact with the air groove 14, the first connecting pipe 18 gradually contacts with the air groove 14, and then the slide groove 16 inhales air from the outside through the first connecting pipe 18, the air groove 14, the first air pipe 15, the arc groove 13, and the air hole, thereby preparing for work again.

[0047] like Figure 2 , Figure 3 , Figure 5As shown, a collecting box 22 is fixedly installed on the workbench 1, and a collecting port cooperating with the cutting disc 8 is opened on the top wall of the collecting box 22. A partition 23 is fixedly installed in the collecting box 22, and a filter screen 24 is slidably installed on the partition 23. A motor 25 electrically connected to the cutting machine 7 is fixedly installed on the side wall of the collecting box 22, and a rotating rod 26 is fixedly installed on the output end of the motor 25. The rotating rod 26 is provided with a fan blade 27, and an exhaust net 28 is embedded in the collecting box 22 near the motor 25.

[0048] A mounting tube 29 is fixedly mounted on the side wall of the partition 23, a push rod 30 is slidably mounted in the mounting tube 29, a brush plate 31 is fixedly mounted on the bottom wall of the push rod 30, bristles 32 are evenly fixedly mounted on the side wall of the brush plate 31, and a second air pipe 33 connected to the air cylinder 9 is inserted into the mounting tube 29.

[0049] A mounting frame 34 is fixedly mounted on the inner wall of the collecting box 22 , an elastic pad 35 is fixedly mounted on the side wall of the mounting frame 34 , the side wall of the elastic pad 35 is fixedly connected to the filter screen 24 , an impact rod 36 is fixedly mounted on the rotating rod 26 , and an inclined block 37 is fixedly mounted on the filter screen 24 .

[0050] A collection box 38 is detachably mounted on the bottom wall of the collection box 22, and the bottom wall of the collection box 22 on the side of the filter 24 away from the motor 25 is an inclined surface. A collection port is provided on the bottom wall of the collection box 22, and a sealing plate 39 is hinged on the side wall of the collection port, and a clockwork 40 is fixedly mounted between the rotating shaft of the sealing plate 39 and the collection box 22.

[0051] By adopting the above technical scheme, during the startup of the cutting machine 7, the motor 25 is energized and drives the rotating rod 26 to rotate, and then drives the fan blades 27 to rotate during the rotation of the rotating rod 26. During the rotation of the fan blades 27, the external airflow is driven to enter the collection box 22 through the collection port and flow to the outside through the filter 24 and the exhaust net 28. During the airflow flowing to the collection box 22, the metal smoke generated during the cutting process can be driven to flow into the collection box 22, thereby effectively preventing the metal smoke from being inhaled by the staff and affecting their health. At the same time, during the airflow entering the collection box 22, the debris generated during the cutting process can be driven into the collection box 22, thereby reducing the cleaning frequency of the user, that is, reducing the time wasted by the user on cleaning the debris. In addition, during the rotation of the fan blades 27, the airflow around the cutting disk 8 can be accelerated, thereby accelerating the heat dissipation effect of the cutting disk 8, that is, effectively preventing the cutting disk 8 from being overheated and deformed, resulting in rapid wear of the cutting disk 8, thereby reducing the frequency of replacement of the cutting disk 8 by the staff, thereby improving the cutting effect.

[0052] In the process of the piston rod 10 moving upward along the air cylinder 9, the air flow in the air cylinder 9 is driven to flow into the mounting cylinder 29 through the second air pipe 33, and then the push rod 30 drives the brush plate 31 to move downward under the action of the air flow. In the process of the brush plate 31 moving downward, the bristles 32 are driven to move and clean the debris on the surface of the filter screen 24, thereby effectively preventing the debris from clogging the filter screen 24, thereby ensuring the normal operation of the filter screen 24. In the process of the piston rod 10 moving downward along the air cylinder 9, the air cylinder 9 inhales air from the mounting cylinder 29 through the second air pipe 33, and then the push rod 30 drives the brush plate 31 to reset under the action of the air flow, thereby preparing for work again.

[0053] During the rotation of the rotating rod 26, the impact rod 36 is driven to rotate. During the rotation of the impact rod 36, it gradually contacts the inclined surface of the inclined block 37 and applies a thrust to the inclined block 37. Then, under the action of the thrust, the inclined block 37 drives the filter 24 to move and stretch the elastic pad 35. When the impact rod 36 is out of contact with the inclined block 37, the elastic pad 35 contracts and drives the filter 24 to reset. That is, during the rotation of the rotating rod 26, the filter 24 can be driven to shake back and forth. Then, during the shaking back and forth of the filter 24, the debris on the filter 24 can be loosened, which makes it easier for the bristles 32 to clean the debris on the filter 24, thereby achieving a cleaning effect.

[0054] Under the action of gravity, the debris on the bottom wall of the collection box 22 gradually moves toward the top wall of the sealing plate 39 along the inclined surface of the bottom wall of the collection box 22, and then gradually contacts the sealing plate 39 during the downward movement of the brush plate 31 and applies a downward thrust to the sealing plate 39. Under the action of the thrust, the sealing plate 39 rotates around the hinge point and causes the spring 40 to start storing force. During the rotation of the sealing plate 39, the sealing plate 39 gradually loses contact with the collection port. At this time, the debris moves downward along the collection port into the collection box 38, and then gradually loses contact with the sealing plate 39 during the upward movement of the brush plate 31. At this time, the spring 40 stretches and drives the sealing plate 39 to reset, thereby effectively preventing the debris from adhering to the surface of the filter screen 24 again, thereby improving the cleaning effect. At the same time, when there are too many debris in the collection box 38, the user can directly clean the collection box 38 without stopping the cutting work, thereby improving the cutting efficiency.

[0055] like Figure 3 , Figure 4As shown, a horizontal groove 41 is provided on the collecting box 38, a groove communicating with the outside is provided on the side wall of the horizontal groove 41, a vertical groove 42 is provided on the top wall of the horizontal groove 41, a cavity is provided on the elastic pad 35, an air inlet valve 43 communicating with the outside is inserted on the side wall of the cavity, an exhaust valve 44 is inserted on the bottom wall of the cavity, a horizontal tube 45 communicating with the vertical groove 42 is inserted on the collecting box 38, and the horizontal tube 45 is connected to the exhaust valve 44, and an elastic membrane 46 communicating with the horizontal tube 45 is fixedly installed on the side wall of the collecting box 38.

[0056] A mounting groove connected to the vertical groove 42 is provided on the side wall of the collecting box 38, a sealing rod 47 is slidably installed in the mounting groove, a connecting port 48 connected to the vertical groove 42 is provided on the sealing rod 47, and a second spring 49 is fixedly installed between the sealing rod 47 and the mounting groove.

[0057] The bottom wall of the groove forms an angle of sixty degrees with the horizontal plane.

[0058] By adopting the above technical solution, during the extension of the elastic pad 35, the cavity inhales air from the outside through the air inlet valve 43. During the contraction of the elastic pad 35, the gas in the cavity flows into the elastic membrane 46 through the exhaust valve 44 and the horizontal tube 45, causing the elastic membrane 46 to expand. Then, during the downward movement of the brush plate 31, the gas gradually contacts the sealing rod 47 and applies a thrust to the inclined surface of the sealing rod 47. Under the action of the thrust, the sealing rod 47 moves into the installation groove and squeezes the second spring 49. During the movement of the sealing rod 47, the connecting port 48 is driven to move. When the side wall of the brush plate 31 is fitted with the collecting port, the connecting port 48 contacts the vertical groove 42. At this time, the gas in the elastic membrane 46 passes through the horizontal tube 45. 45, the vertical grooves 42, the horizontal grooves 41, and the grooves blow toward the bristles 32 and make the debris adhered to the bristles 32 separate from the bristles 32, thereby improving the cleaning effect of the bristles 32; at the same time, by setting the elastic membrane 46, the gas in the cavity when the elastic pad 35 shakes can be collected, and then the impact force of the airflow when cleaning the brush, and by setting the sealing rod 47, when the side wall of the brush plate 31 is in contact with the collecting port, the connecting port 48 can be connected with the vertical groove 42, that is, the collecting port is sealed by the brush plate 31 at this time, thereby effectively preventing the debris adhered to the bristles 32 from adhering to the surface of the filter 24 again, and preventing the debris in the collecting box 38 from entering the collecting box 22 through the collecting port.

[0059] When the airflow passes through the groove and blows toward the bristles 32, the bottom wall of the groove is made to form an angle of sixty degrees with the horizontal plane, so that the air blowing from the groove toward the bristles 32 can be tilted downward, thereby driving the debris on the bristles 32 to move forward, thereby improving the cleaning effect.

[0060] Instructions for use: During use, place the steel pipe on the top wall of the first conveyor belt 2 of the conveyor, then start the first conveyor belt 2 and the second conveyor belt 3, and convey the steel pipe to the bottom of the cutting disc 8 during the working process of the first conveyor belt 2, then the user can close the first conveyor belt 2 and the second conveyor belt 3 and start the electric telescopic rod 5, and then the output end of the electric telescopic rod 5 drives the cutting disc 8 to contact the steel pipe through the mounting plate 6 and the cutting machine 7. At this time, the user can start the cutting machine 7 and drive the cutting disc 8 to cut the steel pipe; in the process of the mounting plate 6 moving downward, the air cylinder 9 and the piston rod 10 drive the arc plate 12 to gradually contact the steel pipe and apply pressure to the steel pipe. Since the bottom wall of the arc plate 12 is an arc surface, the steel pipe gradually moves to the middle under the joint action of the pressure and the arc surface; in the process of the arc plate 12 moving downward, it drives The connecting rod 17 gradually contacts with the steel pipe and moves the connecting rod 17 upward along the slide groove 16. At this time, the elastic airbag 19 is stretched and tends to inhale air through the second connecting pipe 20. In the process of the connecting rod 17 moving upward, it drives the second connecting pipe 20 to gradually contact with the air groove 14. At this time, the elastic airbag 19 inhales air from the arc groove 13 through the second connecting pipe 20, the air groove 14, and the first air pipe 15, and creates negative pressure in the arc groove 13. Then, under the action of pressure, the steel pipe and the arc plate 12 are sucked together; in the process of the piston rod 10 moving upward along the air cylinder 9, it drives the airflow in the air cylinder 9 to flow into the mounting cylinder 29 through the second air pipe 33. Then, under the action of the airflow, the push rod 30 drives the brush plate 31 to move downward. In the process of the brush plate 31 moving downward, it drives the bristles 32 to move and clean the debris on the surface of the filter screen 24.
