Description

Technical Field

[0001] This utility model relates to a steel structure cutting device, belonging to the field of building construction technology. Background Technology

[0002] Steel structure cutting equipment is a key piece of equipment that processes steel using different cutting principles. It is widely used in construction, machinery manufacturing, shipbuilding and other fields, and can improve efficiency, ensure accuracy, reduce costs, adapt to complex needs, reduce waste, expand the processing range and improve safety and environmental protection.

[0003] The core of steel structure cutting equipment revolves around five common modules: frame and worktable, cutting execution mechanism, drive and transmission device, control device, and auxiliary device. Different equipment has its own typical differences in composition, and the cooperation of all parts ensures efficient and precise cutting. The inability to adjust the saw blade position of steel structure cutting equipment has multiple negative impacts on processing, severely restricting equipment performance. The equipment struggles to adapt to diverse workpiece sizes, which vary greatly from a few centimeters to several meters. A fixed saw blade either cannot cut workpieces exceeding its default range or requires multiple repositioning and splicing, resulting in cumbersome operation and a high risk of errors. Furthermore, complex cutting requirements cannot be met. Operations such as beveling and multi-angle cutting rely on saw blade position adjustments, while a fixed saw blade can only perform simple straight-line cuts. It is ineffective for complex tasks such as node processing, and positioning errors easily accumulate. A fixed saw blade requires aligning the workpiece with the cutting path, but moving large workpieces is difficult, and fine adjustments are inaccurate. Errors accumulate after multiple cuts, affecting assembly accuracy. Moreover, worn saw blades cannot be compensated for by fine-tuning, leading to a continuous decline in accuracy. Therefore, a steel structure cutting equipment is proposed to address these problems. Utility Model Content

The drive shaft reciprocates along the guide rail 18 under the drive of the slide rod. A saw blade is rotatably connected to the outer side of the drive shaft. The saw blade rotates at high speed and reciprocates under the drive of the drive shaft.

[0006] Preferably, a conveyor belt is slidably connected to the outer side of the base plate, bases are slidably connected to both sides of the conveyor belt, and a centering clamping assembly is fixedly connected to the top of the base.

[0007] Preferably, the centering clamping assembly includes a base, the top of which is fixedly connected to two vertical rods that extend vertically upwards, and the top of each of the two vertical rods is threaded with a horizontal rod.

[0015] Preferably, a movable rod is slidably connected inside the support base, the movable rod passes through the support base and is connected to the rack.

[0016] The beneficial effects of the utility model are: 1. In this utility model, the rotation of the motor drives a series of components such as the turntable, connecting shaft, and connecting plate to rotate, thus forming a phenomenon of mechanical linkage motion. This achieves efficient power transmission, converting the electrical energy of the motor into mechanical energy. After the power of the motor is transmitted through the turntable, connecting shaft, and other components, it can stably drive the slide rod to perform reciprocating motion. Combined with the rotation of the drive shaft driven by the motor, the saw blade simultaneously possesses a composite motion of reciprocating motion and high-speed rotation, which greatly improves cutting efficiency, ensures that steel can be cut quickly, and reduces cutting time. The guide rail plays a strict role in limiting the movement trajectory of the slide rod, ensuring that the slide rod can only reciprocate along the preset path, thereby ensuring that the movement of the drive shaft and the saw blade is precise and controllable, and effectively avoiding the problem of skewed cuts caused by movement deviation.

[0017] 2. In this utility model, the meshing transmission between the sawtooth block and the small gear, large gear, and rack is tight. When the cylinder drives the sawtooth block to move up and down, it can be accurately converted into the linear motion of the rack through gear transmission, thereby driving the clamping plate to move closer or further away synchronously, ensuring accurate centering of the steel to be cut and avoiding cutting size errors caused by positioning deviations. At the same time, the clamping plate moves smoothly under the drive of the rack, with uniform clamping force, which can firmly fix the steel and prevent the steel from shaking during the cutting process, further ensuring the stability of the cutting. The horizontal bar and vertical bar are connected by threads, and the height of the horizontal bar can be easily adjusted by rotation to meet the clamping requirements of steel of different thicknesses. The connecting rod can slide along the horizontal bar, which is convenient for adjusting the position of the top plate and cylinder and other components, reducing the trouble of replacing equipment or components due to changes in steel specifications.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0020] Reference Figures 1 to 3The present invention provides an embodiment of a steel structure cutting device, including a base plate 1. The base plate 1 serves as the basic load-bearing component of the device, providing a stable installation reference for the components above and ensuring the overall structural stability of the device during operation. A motor 2 is fixedly connected to the top of the base plate 1. The motor 2 serves as the source of cutting power. After starting, the motor 2 can output a continuous and stable driving force, providing power support for the operation of the subsequent transmission structure. A turntable 3 is rotatably connected to the drive end of the motor 2. The turntable 3 can rotate stably under the drive of the motor 2.

[0021] The power of motor 2 is transmitted to the subsequent connecting parts through rotational motion, realizing effective power transmission. The inside of turntable 3 is rotatably connected to connecting shaft 13, which rotates synchronously with turntable 3. It can convert the rotational motion of turntable 3 into the motion of connecting plate 14, acting as a bridge for power transmission. The outside of connecting shaft 13 is rotatably connected to connecting plate 14. Connecting plate 14 moves in a circular motion under the drive of connecting shaft 13, and then transmits the motion to transmission shaft 15, realizing the conversion of motion direction and form. The other end of connecting plate 14 is rotatably connected to transmission shaft 15. Transmission shaft 15 rotates under the drive of connecting plate 14, and drives slide rod 16 to move accordingly, ensuring continuous power transmission. The outside of transmission shaft 15 is rotatably connected to slide rod 16. Driven by transmission shaft 15, slide rod 16 can reciprocate along guide rail 18, providing direct power for the motion of drive shaft 19.

[0022] A guide rail 18 is slidably connected to the outer side of the slide rod 16. The guide rail 18 strictly limits the movement trajectory of the slide rod 16, ensuring that the slide rod 16 can only reciprocate along the preset path, thus improving the accuracy of the movement. A limit ring 20 is slidably connected to the outer side of the guide rail 18. The limit ring 20 can limit the drive shaft 19, preventing the drive shaft 19 from deviating or slipping during reciprocating motion, thus ensuring the safety of the cutting process. The drive shaft 19 is slidably connected to the inner side of the limit ring 20. The drive shaft 19 reciprocates along the guide rail 18 under the drive of the slide rod 16, and can also rotate on its own under the drive of the motor 22, providing the composite motion required for cutting the saw blade 21. The saw blade 21 is rotatably connected to the outer side of the drive shaft 19. The saw blade 21 rotates at high speed and reciprocates under the drive of the drive shaft 19, enabling fast and accurate cutting of steel, improving cutting efficiency and cut quality.

[0023] A conveyor belt 4 is slidably connected to the outer side of the base plate 1. The conveyor belt 4 can be driven by power to realize the automatic conveying of steel, and smoothly transport the steel to be cut to the cutting area, reducing the trouble of manual handling. Bases 7 are slidably connected to both sides of the conveyor belt 4. The bases 7 support the centering clamping components above, and the slidable connection with the conveyor belt 4 can adapt to the conveying needs of steel of different specifications, enhancing the versatility of the equipment. The centering clamping components are fixedly connected to the top of the bases 7. When the steel is conveyed to the cutting position, the centering clamping components can quickly center and clamp the steel, prevent the steel from shifting during the cutting process, and ensure the accuracy of the cutting dimensions.

[0024] Reference Figure 1 , Figure 2 , Figure 4 The centering clamping assembly includes a base 7, which provides a stable mounting foundation for the entire centering clamping assembly, allowing each component to maintain a stable relative position during operation and ensuring precise execution of the clamping action. The top of the base 7 is fixedly connected to two vertical rods 8, which extend vertically upwards and provide reliable support for the horizontal bar 9 above, ensuring the horizontality and stability of the horizontal bar 9 after installation. The top of each of the two vertical rods 8 is threadedly connected to the horizontal bar 9, which is fixed to the vertical rods 8 through threaded connection. This not only ensures a firm connection but also allows for height adjustment by rotation to adapt to the clamping requirements of steel of different specifications.

[0025] A connecting rod 10 is slidably connected to the outside of the crossbar 9. The connecting rod 10 can slide flexibly along the crossbar 9 to facilitate the adjustment of the position of the top plate 11, ensuring that components such as the cylinder 24 are aligned with the area to be clamped on the steel. The bottom of the connecting rod 10 is fixedly connected to the top plate 11, which provides a stable mounting platform for the cylinder 24, preventing it from shaking during operation and ensuring the stability of the power output. The bottom of the top plate 11 is fixedly connected to the cylinder 24, which serves as the power source for the centering and clamping action. After starting, the cylinder 24 can drive the sawtooth block 30 to move up and down through telescopic movement, providing power for the subsequent transmission structure.

[0026] A sawtooth block 30 is fixedly connected to the drive end of the cylinder 24. The sawtooth block 30 moves up and down under the drive of the cylinder 24, which can convert the linear motion of the cylinder 24 into the rotational motion of the gear, realizing the transmission and conversion of power. Two large gears 26 are slidably connected to the rear side of the sawtooth block 30. This sliding connection method does not affect the rotation of the large gears 26, but also restricts the position of the large gears 26 to a certain extent, ensuring precise meshing with the small gears 27 and the rack 28. Small gears 27 are slidably connected to the front side of the two large gears 26. The sliding connection between the small gears 27 and the large gears 26 can ensure that the two rotate synchronously, while avoiding mutual interference and ensuring transmission efficiency.

[0027] Both small gears 27 are meshed with sawtooth blocks 30 on their outer sides. When the sawtooth blocks 30 move up and down, they drive the small gears 27 to rotate through meshing, thus smoothly converting linear motion into rotational motion. The bottoms of both large gears 26 are meshed with the tops of both racks 28. When the large gears 26 rotate, they drive the racks 28 to move linearly through meshing with the racks 28, thus realizing a further conversion of power. The bottoms of both racks 28 are fixedly connected with clamping plates 29. The linear motion of the racks 28 drives the clamping plates 29 to move synchronously, so that the two clamping plates 29 move closer or further apart, thereby clamping and releasing the steel and ensuring the stability of the steel during cutting.

[0028] Multiple brackets 17 are fixedly connected to the top of the base plate 1. The brackets 17 extend upward from the bottom and provide stable support for the guide rail 18 above, ensuring that the guide rail 18 will not wobble when the slide rod 16 and drive shaft 19 move, thus ensuring the accuracy of the cutting trajectory. The top of each bracket 17 is fixedly connected to the guide rail 18. After the guide rail 18 is supported and fixed by the brackets 17, it provides a stable path for the reciprocating motion of the slide rod 16 and drive shaft 19, enabling smooth movement along the preset direction.

[0029] Two power rollers 12 are slidably connected to the inner side of the conveyor belt 4. When the two power rollers 12 rotate, they generate friction with the inner side of the conveyor belt 4, driving the conveyor belt 4 to transmit steel. A base frame 6 is fixedly connected to the outer side of each of the two power rollers 12. The base frame 6 supports and fixes the power rollers 12, ensuring that the power rollers 12 can maintain a stable axial position when rotating, ensuring smooth transmission of the conveyor belt 4. A second motor 5 is fixedly connected to the outside of the base frame 6. The second motor 5 serves as the power source for the transmission of the conveyor belt 4. After starting, it can drive the power rollers 12 to rotate, providing continuous power for the operation of the conveyor belt 4.

[0030] A guide rail 18 is slidably connected to the outer side of the drive shaft 19. The guide rail 18 guides and restricts the movement of the drive shaft 19, so that the drive shaft 19 can only reciprocate along the guide rail 18, avoiding deviation from the trajectory and affecting the cutting. A motor 22 is fixedly connected to the outer side of the guide rail 18. The motor 22 is fixed to the outer side of the guide rail 18 and can directly provide rotational power to the drive shaft 19, driving the drive shaft 19 and the saw blade 21 to rotate at high speed to meet the cutting requirements. Multiple connecting rods 23 are fixedly connected to the bottom of the top plate 11. The multiple connecting rods 23 are vertically connected to the top plate 11 and the support plate 25, transferring the supporting force of the top plate 11 to the support plate 25 and ensuring the stability of the support plate 25.

[0031] Multiple connecting rods 23 are fixedly connected to support plates 25 at their bottoms. The support plates 25 are supported and fixed by the connecting rods 23, providing a stable track for the up-and-down sliding of the sawtooth block 30, ensuring that the sawtooth block 30 does not deviate during movement. The sawtooth block 30 is slidably connected to the bottom of the support plates 25, and the support plates 25 guide the sliding of the sawtooth block 30, allowing it to move up and down in a straight line under the drive of the cylinder 24, ensuring precise meshing with the pinion 27. Two pinions 27 are meshed on both sides of the sawtooth block 30. When the sawtooth block 30 moves up and down, it is connected by… The meshing relationship on both sides simultaneously drives the two pinions 27 to rotate, making the transmission structures on both sides operate synchronously and ensuring the symmetry of the centering and clamping. The pinions 27 are rotatably connected to two gear shafts 33, which provide the pinions 27 with a rotation axis, allowing the pinions 27 to rotate smoothly around the gear shafts 33, while driving the large gear 26 to move synchronously. The rack 28 is slidably connected to a support seat 32 on its rear side, which supports and guides the rack 28, allowing the rack 28 to move smoothly along a straight line under the drive of the large gear 26.

[0032] The support base 32 has a sliding connection to a movable rod 31. The movable rod 31 passes through the support base 32 and is connected to the rack 28, further restricting the movement direction of the rack 28 and ensuring that the rack 28 can only move in a straight line, thus ensuring the precise clamping action of the clamping plate 29.

[0033] Working principle: The worker places the steel on the conveyor belt 4 on the base frame 6 and starts the motor 5. The motor 5 drives the power roller 12 to rotate, which in turn drives the conveyor belt 4. The start cylinder 24 moves up and down, which drives the sawtooth block 30 to move up and down. The sawtooth block 30 moves up and down, which drives the meshing small gear 27 to rotate. The small gear 27 drives the gear shaft 33 to rotate. The gear shaft 33 rotates, which drives the large gear 26 to rotate. The large gear 26 rotates, which drives the rack 28 to move along the movable rod 31 on the support base 32, which in turn drives the clamping plate 29 to move, clamping and centering the material.

[0034] The motor 2 on the base plate 1 is started. The motor 2 drives the connecting shaft 13 on the turntable 3 to rotate. The rotation of the connecting shaft 13 drives the connecting plate 14 to make a circular motion, which in turn drives the transmission shaft 15 to rotate. The rotation of the transmission shaft 15 drives the slide rod 16 to reciprocate along the inside of the guide rail 18. Since the other end of the slide rod 16 is connected to the drive shaft 19, it drives the drive shaft 19 to reciprocate along the guide rail 18. The motor 22 starts and drives the drive shaft 19 to rotate, which in turn drives the saw blade 21 to rotate to cut the steel. The base 7 and vertical bar 8 on both sides of the conveyor belt 4 are used to support the horizontal bar 9. The connecting rod 10 connects the top plate 11 and the horizontal bar 9. The limiting ring 20 prevents the drive shaft 19 from slipping. The bracket 17 provides support. The connecting rod 23 connects the support plate 25 and the top plate 11.
