A cutting device for processing steel components for iron towers

Abstract

This invention discloses a cutting device for processing steel components of iron towers, belonging to the field of steel cutting and processing. The cutting device includes a frame, a sliding table slidably connected to the left side of the top of the frame, a sliding limiting block slidably connected to the top of the sliding table, and a fixed platform fixedly installed on the right side of the top of the frame. This invention uses steel feed to drive rollers to rotate, which in turn drives a rubber arc-shaped pressure plate to automatically press down via a linkage mechanism, forming symmetrical clamping forces on both sides of the circular saw. This effectively suppresses workpiece vibration and stress release during the cutting process, preventing safety hazards such as workpiece bounce and saw blade impact at the moment of cutting. The roller rotation synchronously pulls a steel cable, causing a rectangular pressure plate to press down, forming additional constraints on both sides of the cutting area. This avoids burr growth caused by material rigidity instability at the moment of cutting, thereby obtaining a smooth, low-burr cut, reducing subsequent grinding processes, and thus improving processing quality and efficiency.

Description

Technical Field

[0001] This invention relates to the field of steel cutting and processing technology, and in particular to a cutting device for processing steel components of iron towers. Background Technology

[0002] In the construction of steel structure facilities such as power transmission towers and communication towers, a large amount of cutting and blanking operations are required for profiles such as angle steel, channel steel, and I-beams, as well as plates. Circular saw table saws are widely used in this field because of their high cutting efficiency and good cut quality.

[0003] The steel components of the iron tower are heavy and have varying rigidity. Especially during the cutting process, the release of internal stress can easily cause the workpiece to twist or bounce. Existing fixtures often only fix the workpiece from one side or a few points, which cannot provide comprehensive and stable rigid constraints throughout the entire cutting process, especially at the moment of cutting. This can easily lead to the workpiece loosening or being thrown out, or violently colliding with the high-speed rotating saw blade, causing serious safety accidents such as saw blade breakage and workpiece splashing, posing a great threat to the personal safety of operators. In addition, in the final stage of the cutting process, the supporting rigidity of the remaining material of the workpiece drops sharply, resulting in a large number of hard burrs or slag on the lower edge of the cut. This will seriously affect the accuracy and quality of subsequent welding and assembly, and additional grinding and cleaning processes are required, reducing overall production efficiency and increasing production costs.

[0004] Therefore, it is necessary to invent a cutting device for processing steel components of iron towers to solve the above problems. Summary of the Invention

[0034] Reference Figure 1 - Figure 9 A cutting device for processing steel components for iron towers includes a frame 1. A sliding table 11 is slidably connected to the left side of the top of the frame 1, and a sliding limiting block 12 is slidably connected to the top of the sliding table 11. A fixed table 13 is fixedly installed on the right side of the top of the frame 1. A fixing plate that cooperates with the sliding limiting block 12 is fixedly installed on the top of the fixed table 13 for fixing the steel between the sliding limiting block 12 and the fixing plate. A circular saw 14 is provided inside the fixed table 13. Pushing the sliding table 11 can move the steel towards the circular saw 14 for cutting. In actual use, a protective cover needs to be installed on the top of the fixed table 13 for... For safety protection, a support block 4 is provided above the frame 1, and also includes: a roller 53, which is located on the front side of the bottom of the support block 4. The surface of the roller 53 has grooves to increase friction. Both ends of the roller 53 are fixedly connected to connecting rods 54. The bottom of the connecting rods 54 is provided with rubber arc-shaped pressure plates 59; a hollow plate 6, which is fixedly installed on the rear side of the bottom of the support block 4. A sliding plate 62 is slidably connected to the bottom of the hollow plate 6. A return spring 63 is fixedly installed on the top of the sliding plate 62. A connecting ring 64 is fixedly connected to the top of the front end of the sliding plate 62. A steel cable 67 is fixedly connected to the surface of the connecting ring 64.

[0035] Specifically, during the steel cutting process, one side of the steel can be first attached to the side of the fixed plate, and then the position of the sliding limiting block 12 can be adjusted to attach it to the other side of the steel, thus completing the steel limiting; then the sliding table 11 can be pushed to move the steel on its top towards the circular saw 14, and then the circular saw 14 can be started to prepare to cut the steel.

[0036] Reference Figure 2 - Figure 5A support frame 2 is fixedly installed at the top of the fixed platform 13, and a fixed block 3 is fixedly installed at the bottom of the support frame 2. Two bearing blocks 4 are provided and fixedly installed on the left and right sides of the bottom of the fixed block 3 respectively. A support rod 5 is rotatably connected to the front side of the bottom of the bearing block 4. A support shaft 51 is fixedly connected to the inside of the bottom of the support rod 5. A connecting counterweight plate 52 is rotatably connected to the surface of the support shaft 51. A torsion spring 511 is sleeved on the surface of the support shaft 51. The two ends of the torsion spring 511 are fixedly connected between the support rod 5 and the connecting counterweight plate 52 respectively. A roller 53 is rotatably connected to the bottom of the connecting counterweight plate 52. The axis of the roller 53 is used for... A support plate rotatably connected to the surface of the central shaft is fixedly installed at the bottom of the counterweight plate 52, which provides support for the central shaft. A connecting rod 54 is fixedly connected to the left and right sides of the central shaft of the roller 53. The connecting rod 54 is Ω-shaped, and a connecting device 55 is rotatably connected to the surface of the connecting rod 54. The connecting device 55 consists of a fixed sleeve rotatably connected to the surface of the connecting rod 54 and a straight rod fixedly connected to the bottom. When the connecting rod 54 rotates, it pushes the connecting device 55 to move downwards periodically. A connecting piece 56 is rotatably connected to the bottom end of the connecting device 55. The connecting piece 56 consists of two inclined rods, one at the front and one at the back. The bottom ends are fixedly installed on the front and rear sides of the top of the connecting plate 57, forming a stable triangular structure. The bottom end of the connector 56 is fixedly installed with the connecting plate 57. The internal thread of the connecting plate 57 is connected to the threaded adjusting rod 58. The rubber arc-shaped pressure plate 59 is rotatably connected to the bottom end of the threaded adjusting rod 58. The initial height of the rubber arc-shaped pressure plate 59 can be adjusted by rotating the threaded adjusting rod 58, so that the rubber arc-shaped pressure plate 59 can limit steel of different heights. In actual use, the operator can also disassemble the threaded adjusting rod 58 to install a connection with greater resistance between the connecting plate 57 and the rubber arc-shaped pressure plate 59. The spring clip is selected such that the bottom of the rubber arc-shaped pressure plate 59 initially fits against the top of the steel. During use, the rubber arc-shaped pressure plate 59 can also press and limit the left and right sides of the steel cut. The left and right sides of the support shaft 51 are fixedly installed with telescopic support rods 510. There are two telescopic support rods 510 on each side, which are symmetrically arranged. The bottom ends of the two telescopic support rods 510 are rotatably connected to the front and rear sides of the side wall of the rubber arc-shaped pressure plate 59. The telescopic support rods 510 can extend and retract, and can stably support the rubber arc-shaped pressure plate 59.

[0037] Specifically, during the process of moving the steel towards the circular saw 14 by pushing the sliding table 11, the front end of the steel first contacts the roller 53 during its movement. At this time, the steel will push the roller 53 to rotate through friction. Simultaneously, as the steel pushes the roller 53 forward, the roller 53 and the connecting counterweight plate 52 as a whole will rotate along the axis of the support shaft 51. That is, the roller 53 rotates on its own axis while the connecting counterweight plate 52 rotates. During the rotation of the roller 53, its central axis will drive the fixed connecting rod 54 to rotate accordingly. The connecting rod 54 rotates up and down. During the process, the connecting device 55, which is rotatably connected to it, will be pushed downward. At this time, the connecting device 55 will push the connecting plate 57 downward through the connecting piece 56, and the connecting plate 57 will push the rubber arc-shaped pressure plate 59 downward. At this time, the deformation of the rubber arc-shaped pressure plate 59 itself will limit the steel below. Since the two rubber arc-shaped pressure plates 59 are respectively set on the left and right sides of the circular saw 14, the two rubber arc-shaped pressure plates 59 will limit the steel on the left and right sides of the cutting part of the circular saw 14, thereby achieving the effect of limiting the left and right sides of the steel cutting part.

[0038] Reference Figure 6 - Figure 8 A guide rod 61 is fixedly installed inside the hollow plate 6. A circular groove that slides and connects with the guide rod 61 is opened inside the top of the sliding plate 62. The front end of the guide rod 61 is connected to the outside. The front end of the sliding plate 62 extends through the guide rod 61 to the outside. A return spring 63 is sleeved on the surface of the guide rod 61 and fixedly connected to the top wall of the hollow plate 6. A rectangular pressure plate 68 is fixedly installed at the bottom end of the sliding plate 62. A fixing rod 65 is fixedly installed on the bottom surface of the guide rod 61. A guide wheel 66 is fixedly installed at the front end of the fixing rod 65. The end of the steel cable 67 away from the connecting ring 64 passes through the bottom surface of the guide wheel 66 and is wound and connected to the central shaft of the roller 53. A winding ring is rotatably connected to the surface of the central shaft. The winding ring is rotatably connected to the surface of the central shaft through a bearing. Anti-loosening buckles are provided at the edge to prevent the steel cable 67 from loosening. The end of the steel cable 67 away from the connecting ring 64 is wound and connected to the surface of the winding ring. The steel cable 67 is made of stainless steel wire.

[0039] Specifically, during the process of roller 53 rotating due to friction in contact with the steel, roller 53 and the central shaft will rotate. At this time, the central shaft will drive the winding ring to rotate due to friction, and the winding ring will wrap the steel cable 67, thereby pulling the connecting ring 64. Since the fixed rod 65 and guide wheel 66 set at the bottom of the hollow plate 6 are located below the connecting ring 64, the connecting ring 64 will pull down, thereby driving the sliding plate 62 to move downward. At this time, the sliding plate 62 will stretch the return spring 63 inside the hollow plate 6 and drive the rectangular pressure plate 68 to move downward until the rectangular pressure plate 68 contacts the steel below. At this time, the rectangular pressure plates 68 on the left and right sides can further limit the two sides of the steel cutting point, so as to avoid the steel's rigid support disappearing instantly when the last part of the steel is cut through, which would cause slight vibration or sagging, resulting in the circular saw 14 squeezing and plastic deformation of the last bit of material being greater than the cutting, thereby avoiding the formation of larger burrs.

[0040] Reference Figure 6 - Figure 9 A fixed bent rod 7 is fixedly connected to the bottom surface of the hollow plate 6. Electromagnets 71 are fixedly installed inside the left and right sides of the fixed bent rod 7. A hollow guide plate 72 is fixedly installed on the surface of the electromagnet 71. A magnet 73 is slidably connected inside the hollow guide plate 72. The near ends of the magnet 73 and the electromagnet 71 have the same magnetic poles. An anti-slip plate 74 is fixedly installed at the end of the magnet 73 away from the electromagnet 71. A damping block 75 is fixedly installed at the top of the hollow guide plate 72. The top of the magnet 73 and the damping block 75 are slidably connected and adapted to each other. Rectangular openings are provided on the left and right sides of the bottom of the hollow plate 6. Pressure sensors 77 are fixedly installed inside the groove 76 and the left and right sides of the rectangular pressure plate 68. The bottom end of the pressure sensor 77 is flush with the bottom end of the rectangular pressure plate 68. The pressure sensor 77 is electrically connected to the electromagnet 71 and is connected to the microcontroller via signal connection. A mobile power supply for powering the pressure sensor 77 is installed at the top of the rectangular pressure plate 68. Before use, the pressure threshold of the pressure sensor 77 can be set according to the type of steel to be cut to avoid deformation of the steel due to excessive pressure when the rectangular pressure plate 68 presses on hollow or thin steel.

[0041] Specifically, during the process of the rectangular pressure plate 68 driving the pressure sensor 77 to lower the steel, when the pressure sensor 77 detects that the pressure has reached the threshold, the pressure sensor 77 will energize the electromagnet 71 through the microcontroller. At this time, the electromagnet 71 will repel the magnet 73 with the same magnetic pole, and the magnet 73 will drive the anti-slip plate 74 through the rectangular groove 76 to abut against the surface of the sliding plate 62. The friction between the anti-slip plate 74 and the sliding plate 62 will limit the sliding plate 62, thereby preventing the sliding plate 62 from moving further downward. This will prevent the sliding plate 62 from driving the rectangular pressure plate 68 to press the steel excessively and causing it to deform. Before the magnet 73 is repelled by the electromagnet 71, the damping effect of the damping block 75 will also prevent the magnet 73 from shaking and ensure the stability of subsequent movement.

[0042] Furthermore, after the rectangular pressure plate 68 can no longer move downwards, if the steel is pushed to overcome the resistance of the rectangular pressure plate 68 and the rubber arc pressure plate 59 and move slowly to cut, that is, at this time the roller 53 is still slowly rotating under the action of the friction of the steel, while the sliding plate 62 can no longer move downwards and the steel cable 67 can no longer be pulled, the winding wheel that winds the steel cable 67 will overcome the friction with the central axis of the roller 53 and rotate on the surface of the central axis, so that the roller 53 can still continue to rotate on the surface of the steel.

[0043] In this invention, during the cutting of steel, one side of the steel can be first attached to the side of the fixed plate, and then the position of the sliding limiting block 12 can be adjusted so that it is attached to the other side of the steel, thus completing the limitation of the steel; then the sliding table 11 can be pushed to move the steel on its top towards the circular saw 14, and then the circular saw 14 can be started to prepare to cut the steel.

[0044] During the process of moving the steel material towards the circular saw 14 via the sliding table 11, the front end of the steel material first contacts the roller 53. The steel material then pushes the roller 53 to rotate due to friction. Simultaneously, as the steel material pushes the roller 53 forward, the roller 53 and the connecting counterweight plate 52, as a whole, rotate along the axis of the support shaft 51. That is, the roller 53 rotates on its own axis as the connecting counterweight plate 52 rotates, until the roller 53, along with the connecting counterweight plate, rotates to contact the top of the steel plate. At this point, the connecting counterweight plate 52 stops rotating, and only the roller 53 rotates on its own axis. During the rotation of the roller 53, its central axis drives the solid... The fixed connecting rod 54 rotates accordingly. During the up-and-down rotation, the connecting rod 54 periodically pushes the connecting device 55, which is rotatably connected to it, to move downward. At this time, the connecting device 55 pushes the connecting plate 57 downward through the connecting piece 56, and the connecting plate 57 pushes the rubber arc-shaped pressure plate 59 downward. At this time, the deformation of the rubber arc-shaped pressure plate 59 itself restricts the steel below. Since the two rubber arc-shaped pressure plates 59 are respectively set on the left and right sides of the circular saw 14, the two rubber arc-shaped pressure plates 59 restrict the steel on the left and right sides of the cutting part of the circular saw 14, thereby achieving the effect of restricting the left and right sides of the steel cutting part.

[0045] As the roller 53 rotates due to friction in contact with the steel, the roller 53 and the central shaft rotate. At this time, the central shaft drives the winding ring to rotate due to friction, and the winding ring winds the steel cable 67, thereby pulling the connecting ring 64. Since the fixed rod 65 and guide wheel 66 set at the bottom of the hollow plate 6 are located below the connecting ring 64, the connecting ring 64 will pull downward, thereby driving the sliding plate 62 to move downward. At this time, the sliding plate 62 will stretch the return spring 63 inside the hollow plate 6 and drive the rectangular pressure plate 68 to move downward until the rectangular pressure plate 68 contacts the steel below. At this time, the rectangular pressure plates 68 on the left and right sides can further limit the two sides of the steel cutting point, so as to avoid the steel's rigid support disappearing instantly when the last part of the steel is cut through, which would cause slight vibration or sagging, resulting in the circular saw 14 squeezing and plastic deformation of the last bit of material being greater than the cutting, thereby avoiding the formation of larger burrs.

[0046] During the process of the rectangular pressure plate 68 driving the pressure sensor 77 to lower the steel, when the pressure sensor 77 detects that the pressure has reached the threshold, the pressure sensor 77 will energize the electromagnet 71 through the microcontroller. At this time, the electromagnet 71 will repel the magnet 73 with the same magnetic pole, and the magnet 73 will drive the anti-slip plate 74 through the rectangular groove 76 to abut against the surface of the sliding plate 62. The friction between the anti-slip plate 74 and the sliding plate 62 will limit the sliding plate 62, thereby preventing the sliding plate 62 from moving further downward. This will prevent the sliding plate 62 from driving the rectangular pressure plate 68 to press the steel excessively and causing it to deform. Before the magnet 73 is repelled by the electromagnet 71, the damping effect of the damping block 75 will also prevent the magnet 73 from shaking and ensure the stability of subsequent movement. Furthermore, after the rectangular pressure plate 68 can no longer move downwards, if the steel is pushed to overcome the resistance of the rectangular pressure plate 68 and the rubber arc pressure plate 59 and move slowly to cut, that is, at this time the roller 53 is still slowly rotating under the action of the friction of the steel, while the sliding plate 62 can no longer move downwards and the steel cable 67 can no longer be pulled, the winding wheel that winds the steel cable 67 will overcome the friction with the central axis of the roller 53 and rotate on the surface of the central axis, so that the roller 53 can still continue to rotate on the surface of the steel.
