[0024] The processing technology of hot-rolled section steel includes the following steps:

[0025] S1: Prepare materials, check the hot-rolled section steel, and check whether the components of the band saw are normal;

[0026] S2: Clamp the workpiece, place the hot-rolled section steel on the steel loading unit of the band saw, and firmly clamp the section steel;

[0027] S3: Sawing process, the driving unit will drive the band saw unit to make reciprocating movements to saw the hot-rolled section steel;

[0028] S4: Quality inspection, measure the size of the sawn section steel and observe the roughness of the sawn surface after sawing.

[0029] The beneficial effects of the present invention are as follows:

[0030] 1. The present invention sets a tensioning mechanism. The detector will detect the tension on the surface of the saw blade. If the tension is too small, the servo motor will drive the reciprocating screw to rotate, and then drive the moving splint to move in the direction of the servo motor, so that the tension of the saw blade becomes larger. The adjusted tension force data is fed back to the control platform in real time to ensure that the tension force is always kept within the appropriate range.

[0031] 2. The present invention sets a monitoring mechanism and a vibration detector to detect the vibration frequency of the saw blade. If the vibration frequency is high, it means that the waste chips generated during cutting are attached to the guide rod 2, causing the reciprocating movement of the mobile platform to generate a large friction force and thus generate vibration. At this time, water is sprayed toward the entire reciprocating unit through the nozzle on the water pump. The impact force of the water will cause the waste chips on the guide rod 2 to fall off, and the water flow will also cool the saw blade.

[0032] 3. The present invention sets a monitoring mechanism. As water flows into the water accumulation plate, the weight in the water accumulation plate increases, thereby causing the rotating plate to rotate and driving the rubber scraper to come into contact with the side of the vibration detector that contacts the saw blade, scraping off the waste generated during cutting, so that the vibration detector can be in direct contact with the saw blade, avoiding the waste from being between the vibration detector and the saw blade, so that the vibration detector cannot correctly detect the vibration frequency of the saw blade.

[0033] 4. The present invention sets a control unit to allow the hot-rolled steel to pass through the control frame, so that the end of the hot-rolled steel that is about to be cut is supported by the control frame to avoid burrs on the bottom of the cut, and the telescopic spring plays a buffering role. When the telescopic rod 1 is retracted upward, that is, when the saw blade is reset, the light measuring device will detect the light beam emitted by the spectrometer, so that the telescopic rod 2 drives the support plate 2 to move upward, so that the cut hot-rolled steel slides onto the lower slide chute and finally falls into the collection box.

The embodiments are chosen and described in order to better illustrate the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0050] Example 1, using Figures 1 - 14 The band sawing machine and processing technology for hot-rolled steel sections in one embodiment of the present invention will be described as follows.

[0051] As Figures 1 - 3 shown, the band sawing machine for hot-rolled steel sections of the present invention includes a bed body 1 provided with a lower chute 12, a processing box 4 is provided on the top of the bed body 1, a main motor 5 is provided on the top of the processing box 4, the output end of the main motor 5 is connected to a transmission 6, and further includes:

[0052] A band saw unit 7 for cutting hot-rolled steel sections;

[0053] A driving unit 2 for driving the band saw unit 7 to reciprocate;

[0054] A control unit 8 for maintaining the stability when the hot-rolled steel section breaks and preventing burrs from being generated;

[0055] A steel bar loading unit 9 for placing steel bars and controlling the smooth movement of the steel bars;

[0056] A cutting table 3 is further provided on the top of the bed body 1, a first rotating shaft 13 is provided at the bottom of the transmission 6, and the end of the first rotating shaft 13 away from the transmission 6 is fixedly connected to the driving unit 2. The main motor 5 will drive the transmission 6 to operate and make the driving unit 2 work through the first rotating shaft 13;

[0057] When the present invention works, first, the saw blade 7567 is installed and fixed. The steel bar loading unit 9 will move the position of the hot-rolled steel section to be cut to the band saw unit 7. Then, the main motor 5 will drive the transmission 6 to operate and make the driving unit 2 rotate through the transmission of the first rotating shaft 13, and make the band saw unit 7 cut the hot-rolled steel section. During the cutting process, the control unit 8 will control the hot-rolled steel section to prevent it from tilting.

[0058] As Figure 4As shown in the figure, the driving unit 2 includes an outer frame 21. A first transmission wheel 22 is rotatably connected to the inner wall of the outer frame 21. A second transmission wheel 23 is also provided on the inner wall of the outer frame 21. The first transmission wheel 22 is located at the bottom of the second transmission wheel 23 and is linked together by a chain 24. An eccentric shaft 25 is fixedly connected to the outer surface of the second transmission wheel 23. A connecting rod 26 is fixedly connected to the outer surface of the eccentric shaft 25. One end of the connecting rod 26 away from the eccentric shaft 25 is fixedly connected to a universal shaft 27.

[0059] As the first rotating shaft 13 rotates, it will drive the first transmission wheel 22 to rotate. Through the transmission of the chain 24, the second transmission wheel 23 rotates and finally drives the eccentric wheel to rotate. Due to the connection of the connecting rod 26 and the universal shaft 27 to the moving platform 755, the moving platform 755 can reciprocate along the second guide rod 754.

[0060] A collection box 11 is provided at the bottom of the bed body 1 for collecting the cut hot-rolled steel sections. A control platform 10 for the operator to operate the band saw is also provided on the top of the bed body 1.

[0061] One side of the outer frame 21 is fixedly connected to the outer surface of the processing box 4. The end of the first rotating shaft 13 away from the transmission 6 is fixedly connected to the outer surface of the first transmission wheel 22.

[0062] As Figures 5 - 6 As shown in the figure, the band saw unit 7 includes a support frame 71. The number of support frames 71 is two. The support frames 71 are symmetrically arranged on the inner wall of the processing box 4. An oil cylinder 72 is provided on the outer surface of the support frame 71 for providing a downward thrust. A first telescopic rod 73 is provided at the output end of the oil cylinder 72. A reciprocating unit 75 is provided at the bottom of the first telescopic rod 73. First guide rods 76 are symmetrically arranged at the bottom of the processing box 4 for controlling the downward movement direction of the first telescopic rod 73.

[0063] During cutting, the oil cylinder 72 will first drive the first telescopic rod 73 to move downward. At the same time, the reciprocating unit 75 will also start to work, enabling the saw blade 7567 to cut the steel body.

[0064] The band saw unit 7 further includes a water pump 74. The water pump 74 is provided on the outer surface of the processing box 4. Nozzles 78 are evenly arranged on the outer surface of the water pump 74. The nozzles 78 face the reciprocating unit 75. A water pipe 77 for introducing water source is provided on the outer surface of the water pump 74.

[0065] During the cutting process, the nozzles 78 will spray cooling water on the reciprocating unit 75.

[0066] As Figure 7As shown in the figure, the reciprocating unit 75 includes a support block 751 provided with a circular groove 752 adapted to the first guide rod 76. A spectroscope 753 capable of emitting specific light is provided on the outer surface of the support block 751. Opposite surfaces of the support block 751 are fixedly connected with a second guide rod 754. A moving platform 755 is slidably connected to the outer surface of the second guide rod 754. A tensioning mechanism 756 is provided at the bottom of the moving platform 755 for keeping the cutting tool in a taut state. A monitoring mechanism 757 is provided on the outer surface of the tensioning mechanism 756 for detecting the vibration frequency of the tool during cutting.

[0067] The specific working process is as follows:

[0068] During operation, the main motor 5 drives the transmission 6 to operate and rotates the drive unit 2 through the transmission of the first rotating shaft 13. As the first rotating shaft 13 rotates, the first transmission wheel 22 rotates. Through the transmission of the chain 24, the second transmission wheel 23 rotates and finally drives the eccentric wheel to rotate. Due to the connection of the connecting rod 26 and the universal shaft 27 to the moving platform 755, the moving platform 755 can reciprocate along the second guide rod 754.

[0069] Embodiment 2, use Figures 1 - 14 A band sawing machine and processing technology for hot-rolled steel sections according to an embodiment of the present invention will be described as follows.

[0070] As Figure 8 As shown in the figure, based on Embodiment 1, the tensioning mechanism 756 of the band sawing machine for hot-rolled steel sections of the present invention includes a frame body 7561 provided with a gap 7562 allowing water to pass through. A servo motor 7563 is fixedly connected to the outer surface of the frame body 7561. The output end of the servo motor 7563 is fixedly connected with a reciprocating screw rod 7564. A moving clamping plate 7565 is threadedly connected to the outer surface of the reciprocating screw rod 7564. A fixed support plate 7566 is provided at one end of the frame body 7561 away from the servo motor 7563. The moving clamping plate 7565 and the fixed clamping plate jointly clamp the saw blade 7567. A tension detector 7568 is provided on the moving clamping plate 7565 for detecting the tension of the saw blade 7567.

[0071] During the process of the drive unit 2 driving the whole band saw unit to reciprocate, the saw blade 7567 cuts the hot-rolled steel section. At the same time, the tension detector 7568 detects the tension on the surface of the saw blade 7567. If the tension is small, the servo motor 7563 will drive the reciprocating screw rod 7564 to rotate, thereby driving the moving clamping plate 7565 to move towards the servo motor 7563, increasing the tension of the saw blade 7567, and real-time feedback of the adjusted tension data to the control platform 10 to ensure that the tension is always maintained within a suitable range.

[0072] As Figures 9 - 10As shown, the monitoring mechanism 757 includes a vibration detector 7571, a support plate 7572 is provided at the bottom of the vibration detector 7571, a support column 7573 is fixedly connected to the outer surface of the support plate 7572, a rotating plate 7574 is rotatably connected to the outer surface of the support column 7573, a rubber scraper 7575 is provided at the end of the rotating plate 7574 close to the saw blade 7567, a water accumulation plate 7576 is provided at the end of the rotating plate 7574 away from the rubber scraper 7575, a water accumulation plate 7576 is provided on the outer surface of the water accumulation plate 7576, a water leakage hole 7577 is provided, and a flap 7578 is rotatably connected to the inner wall of the water accumulation plate 7576;

[0073] During the hot-rolled steel cutting process, not only is the tension of the saw blade 7567 monitored, but the vibration frequency of the saw blade 7567 is also detected by setting a vibration detector 7571. If the vibration frequency is high, it means that the waste generated during cutting is attached to the second guide rod 754, causing the reciprocating movement of the mobile platform 755 to generate a large friction force, thereby generating vibration. At this time, water is sprayed toward the entire reciprocating unit 75 through the nozzle 78 on the water pump 74. The impact force of the water causes the waste to fall off the second guide rod 754.

[0074] Under normal circumstances, the weight of the rubber scraper 7575 is greater than the weight of the water accumulation plate 7576 as a whole, but as water flows into the water accumulation plate 7576, the weight of the water accumulation plate 7576 will increase, thereby causing the rotating plate 7574 to rotate and drive the rubber scraper 7575 to come into contact with the side of the vibration detector 7571 that is in contact with the saw blade 7567, scraping off the waste generated during cutting, so that the vibration detector 7571 can be in direct contact with the saw blade 7567, avoiding the presence of waste between the vibration detector 7571 and the saw blade 7567, so that the vibration detector 7571 cannot correctly detect the vibration frequency of the saw blade 7567.

[0075] The top of the vibration detector 7571 is fixedly connected to the bottom of the frame 7561 , and the vibration detector 7571 comes into contact with the side of the saw blade 7567 .

[0076] The top of the support block 751 is fixedly connected to the bottom of the telescopic rod 73, and the top of the frame 7561 is fixedly connected to the bottom of the mobile platform 755.

[0077] like Figures 11 - 12As shown in the figure, the control unit 8 includes a support rod 81. One end of the support rod 81 is provided with an outer box 82. The top of the outer box 82 is fixedly connected with a light measuring device 83. The light measuring device 83 can detect the light beam emitted by the spectroscope 753. The inner wall of the outer box 82 is fixedly connected with a second telescopic rod 84. The bottom of the second telescopic rod 84 is fixedly connected with a second support plate 85. The bottom of the second support plate 85 is evenly provided with telescopic springs 86. The bottom of the telescopic springs 86 is fixedly connected with a third support plate 87. The bottom of the third support plate 87 is provided with a limiting block 88. A control frame 89 adapted to a specific-shaped hot-rolled steel section is clamped in the limiting block 88;

[0078] During the cutting process, when the hot-rolled steel section is about to be cut off, because the weights on both sides of the steel body located on both sides of the cutting table 3 are different, it will tilt. Therefore, when cutting the hot-rolled steel section, the hot-rolled steel section will be passed through the control frame 89, so that the end that is about to tilt when the hot-rolled steel section is about to be cut off is blocked by the bottom column of the control frame 89. The telescopic spring 86 plays a buffering role. When the first telescopic rod 73 retracts upward, that is, when driving the saw blade 7567 to reset, the light measuring device 83 will detect the light beam emitted by the spectroscope 753, so that the second telescopic rod 84 drives the second support plate 85 to move upward, making the cut hot-rolled steel section slide onto the lower chute 12 and finally fall into the collection box 11.

[0079] The top of the support rod 81 is fixedly connected to the outer surface of the processing box 4.

[0080] As Figure 13 shown in the figure, the steel-carrying unit 9 includes a transfer plate 91. The bottom of the transfer plate 91 is evenly provided with support bases 92. One side of the transfer plate 91 is provided with a driver 93. The outer surface of the driver 93 is rotatably connected with a roller 94. The top of the driver 93 is also provided with a first abutting plate 95. The side of the transfer plate 91 away from the driver 93 is provided with a support platform 96. The top of the support platform 96 is evenly provided with hydraulic rods 97. The output ends of the hydraulic rods 97 are fixedly connected with second abutting plates 98;

[0081] Before cutting, the hot-rolled steel section will be placed on the transfer plate 91 first. When cutting is required, the driver 93 will drive the roller 94 to rotate, thereby driving the hot-rolled steel section to move, making the part to be cut move to the cutting table 3. Then the hydraulic rod 97 will drive the second abutting plate 98 to move towards the first abutting plate 95, fixing the hot-rolled steel section between the first abutting plate 95 and the second abutting plate 98.

[0082] The hot-rolled steel section is placed on the transfer plate 91 and is moved by the roller 94. When cutting, the first abutting plate 95 and the second abutting plate 98 will fix the hot-rolled steel section.

[0083] The specific working process is as follows:

[0084] During operation, the tension detector 7568 detects the surface tension of the saw blade 7567. If the tension is too low, the servo motor 7563 drives the reciprocating screw 7564 to rotate, thereby driving the movable splint 7565 to move toward the direction of the servo motor 7563, thereby increasing the tension of the saw blade 7567. At the same time, the vibration detector 7571 detects the vibration frequency of the saw blade 7567. If the vibration frequency is too high, the nozzle 78 on the water pump 74 sprays water toward the entire reciprocating unit 75. The impact force of the water will cause the guide When waste chips fall off the rod 2 754, water will flow into the water accumulation plate 7576. The weight in the water accumulation plate 7576 will increase, causing the rotating plate 7574 to rotate and drive the rubber scraper 7575 to come into contact with the side of the vibration detector 7571 and the saw blade 7567, thereby scraping off the waste chips generated during cutting. During the cutting process, the hot-rolled steel section will pass through the control frame 89, so that the end of the hot-rolled steel section that is about to be lifted up when it is about to be cut will be supported by the control frame 89 to avoid burrs at the bottom of the cut.

[0085] like Figure 14 As shown, the hot rolled steel processing technology includes the following steps:

[0086] S1: Prepare materials, inspect hot-rolled steel sections, and check whether all parts of the band saw are normal;

[0087] S2: Clamp the workpiece, place the hot-rolled steel on the steel loading unit of the band saw, and clamp the steel firmly;
