[0014] The beneficial effects of the present invention are as follows: 1. The present invention sets a tensioning mechanism, and the detector detects the tension on the surface of the saw blade.

[0015] 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.

[0016] 3. The present invention sets a monitoring mechanism. As water flows into the water accumulation plate, the weight in the water accumulation plate will increase, so that the rotating plate will rotate and drive the rubber scraper to contact the side of the vibration detector that contacts the saw blade, so as to scrape off the waste generated during cutting, so that the vibration detector can be in direct contact with the saw blade, avoiding the existence of waste between the vibration detector and the saw blade, and making it impossible for the vibration detector to correctly detect the vibration frequency of the saw blade.

[0017] 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 lifted up when it is about to be cut is held by the control frame, thereby avoiding burrs at 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 driven to 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 sliding groove and finally falls into the collection box.

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

[0036] like Figure 4 As shown, the driving unit 2 includes an outer frame 21, the inner wall of the outer frame 21 is rotatably connected to a transmission wheel 1 22, the inner wall of the outer frame 21 is also provided with a transmission wheel 23, the transmission wheel 1 22 is located at the bottom of the transmission wheel 23 and is linked together through a chain 24, the outer surface of the transmission wheel 23 is fixedly connected to an eccentric shaft 25, the outer surface of the eccentric shaft 25 is fixedly connected to a connecting rod 26, and the end of the connecting rod 26 away from the eccentric shaft 25 is fixedly connected to a universal shaft 27.

[0037] As the rotating shaft 13 rotates, the transmission wheel 1 22 will be driven to rotate, and the transmission wheel 2 23 will be rotated through the transmission of the chain 24 and finally the eccentric wheel will be driven to rotate. Due to the connection between the connecting rod 26 and the universal joint 27 and the mobile platform 755, the mobile platform 755 can reciprocate along the guide rod 2 754.

[0038] A collecting box 11 is provided at the bottom of the bed 1 for collecting the cut hot-rolled steel sections, and a control platform 10 for an operator to operate the band saw is also provided on the top of the bed 1; One side of the outer frame 21 is fixedly connected to the outer surface of the processing box 4 , and one end of the rotating shaft 13 away from the transmission 6 is fixedly connected to the outer surface of the transmission wheel 22 .

[0039] like Figure 5-Figure 6As shown, the band saw unit 7 includes a support frame 71, the number of the support frames 71 is two, the support frames 71 are symmetrically arranged on the inner wall of the processing box 4, the outer surface of the support frame 71 is provided with a cylinder 72 for providing a downward thrust, the output end of the cylinder 72 is provided with a telescopic rod 73, the bottom of the telescopic rod 73 is provided with a reciprocating unit 75, and the bottom of the processing box 4 is symmetrically provided with a guide rod 76 for controlling the downward movement direction of the telescopic rod 73; When cutting, the oil cylinder 72 will first drive the telescopic rod 73 to move downward, and at the same time the reciprocating unit 75 will also start working, so that the saw blade 7567 can cut the steel body.

[0040] The band saw unit 7 also includes a water pump 74 , which is arranged on the outer surface of the processing box 4 , and the outer surface of the water pump 74 is evenly provided with nozzles 78 , the nozzles 78 face the reciprocating unit 75 , and the outer surface of the water pump 74 is provided with a water pipe 77 for introducing a water source.

[0041] During the cutting process, the nozzle 78 sprays cooling water to the reciprocating unit 75 .

[0042] like Figure 7 As shown, the reciprocating unit 75 includes a support block 751 provided with a circular groove 752 adapted to the guide rod 1 76, the outer surface of the support block 751 is provided with a spectrometer 753 capable of emitting specific light, the opposite surface of the support block 751 is fixedly connected with a guide rod 2 754, the outer surface of the guide rod 2 754 is slidably connected with a moving platform 755, the bottom of the moving platform 755 is provided with a tensioning mechanism 756 for keeping the tool in a taut state, the outer surface of the tensioning mechanism 756 is provided with a monitoring mechanism 757 for detecting the vibration frequency of the tool during cutting.

[0043] The specific workflow is as follows: During operation, the main motor 5 drives the transmission 6 to operate and rotates the drive unit 2 through the transmission of the rotating shaft 13. As the rotating shaft 13 rotates, the transmission wheel 22 is driven to rotate, and the transmission wheel 2 23 is rotated through the transmission of the chain 24 and finally drives the eccentric wheel to rotate. Due to the connection between the connecting rod 26 and the universal joint 27 and the mobile platform 755, the mobile platform 755 can reciprocate along the guide rod 2 754.

[0044] Embodiment 2, use Figure 1-Figure 14 A band saw machine and a processing process for hot-rolled steel processing according to an embodiment of the present invention are described below.

[0045] like Figure 8As shown, the band saw machine for hot-rolled steel processing of the present invention is based on the first embodiment, and the tensioning mechanism 756 includes a frame 7561 provided with a gap 7562 allowing water to pass through, the outer surface of the frame 7561 is fixedly connected to a servo motor 7563, the output end of the servo motor 7563 is fixedly connected to a reciprocating screw rod 7564, the outer surface of the reciprocating screw rod 7564 is threadedly connected to a movable clamping plate 7565, and a fixed frame plate 7566 is provided at one end of the frame 7561 away from the servo motor 7563, and the movable clamping plate 7565 and the fixed clamping plate jointly clamp the saw blade 7567, and a tension detector 7568 is provided on the movable clamping plate 7565 for detecting the tension of the saw blade 7567.

[0046] When the driving unit 2 drives the whole band saw unit to make reciprocating motion, the saw blade 7567 will cut the hot-rolled steel, and the tension detector 7568 will detect 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, and then drive the moving clamp 7565 to move in the direction of the servo motor 7563, so that the tension of the saw blade 7567 becomes larger, and the adjusted tension force data is fed back to the control platform 10 in real time to ensure that the tension force is always kept within the appropriate range.

[0047] like Figure 9-10 As 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 leakage hole 7577 is provided on the outer surface of the water accumulation plate 7576, and a flap 7578 is rotatably connected to the inner wall of the water accumulation plate 7576; In the process of cutting the hot-rolled steel, not only the tension of the saw blade 7567 is monitored, but also the vibration frequency of the saw blade 7567 is detected by setting a vibration detector 7571. If the vibration frequency is high, it means that the waste generated during cutting adheres to the second guide rod 754, so that the reciprocating movement of the mobile platform 755 generates a large friction force and thus generates vibration. At this time, water is sprayed toward the overall reciprocating unit 75 through the nozzle 78 on the water pump 74, and the impact force of the water causes the waste on the second guide rod 754 to fall off; Under normal circumstances, the weight of the rubber scraper 7575 is greater than the overall weight of the water accumulation plate 7576. However, as water flows into the water accumulation plate 7576, the weight of 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 that is in contact with the saw blade 7567, thereby scraping off the waste generated during cutting and allowing the vibration detector 7571 to come into direct contact with the saw blade 7567, thereby avoiding the presence of waste between the vibration detector 7571 and the saw blade 7567, which would prevent the vibration detector 7571 from correctly detecting the vibration frequency of the saw blade 7567.

[0048] The top of the vibration detector 7571 is fixedly connected to the bottom of the frame 7561 , and the vibration detector 7571 will come into contact with the side of the saw blade 7567 .

[0049] 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.

[0050] like Figure 11-Figure 12 As shown, the control unit 8 includes a support rod 81, an outer box 82 is provided at one end of the support rod 81, a light measuring device 83 is fixedly connected to the top of the outer box 82, and the light measuring device 83 can detect the light beam emitted by the spectrometer 753, and a telescopic rod 84 is fixedly connected to the inner wall of the outer box 82, and a support plate 85 is fixedly connected to the bottom of the telescopic rod 84, and a telescopic spring 86 is evenly arranged at the bottom of the support plate 85, and a support plate 3 87 is fixedly connected to the bottom of the telescopic spring 86, and a limit block 88 is provided at the bottom of the support plate 3 87, and a control frame 89 adapted to a specific shape of hot-rolled steel is clamped in the limit block 88; During the cutting process, when the hot-rolled steel is about to be cut off, the weight of the steel body on both sides of the cutting table 3 is different, so it will tilt. Therefore, when cutting the hot-rolled steel, the hot-rolled steel will pass through the control frame 89, so that the end of the hot-rolled steel that is about to be lifted up when it is about to be cut is controlled by the bottom column of the control frame 89, and the telescopic spring 86 plays a buffering role. When the telescopic rod 1 73 is retracted upward, that is, the saw blade 7567 is driven to reset, the light measuring device 83 will detect the light beam emitted by the spectrometer 753, so that the telescopic rod 2 84 drives the support plate 2 85 to move upward, so that the cut hot-rolled steel slides onto the lower slide groove 12 and finally falls into the collection box 11.

[0051] The top of the support rod 81 is fixedly connected to the outer surface of the processing box 4 .

[0052] like Fig.13As shown, the steel carrying unit 9 includes a transmission plate 91, a support base 92 is evenly arranged at the bottom of the transmission plate 91, a driver 93 is arranged on one side of the transmission plate 91, a roller 94 is rotatably connected to the outer surface of the driver 93, a first abutment plate 95 is also arranged on the top of the driver 93, a support platform 96 is arranged on the side of the transmission plate 91 away from the driver 93, a hydraulic rod 97 is evenly arranged on the top of the support platform 96, and an output end of the hydraulic rod 97 is fixedly connected to a second abutment plate 98; Before cutting, the hot-rolled steel will be placed on the transmission plate 91. When cutting is required, the driver 93 will drive the roller 94 to rotate, thereby driving the hot-rolled steel to move, so that the part that needs to be cut is moved to the cutting table 3. Then the hydraulic rod 97 will drive the second plate 98 to move toward the first plate 95, so that the hot-rolled steel is fixed between the first plate 95 and the second plate 98.

[0053] The hot-rolled steel is placed on the transmission plate 91 and is moved by the roller 94. The first abutment plate 95 and the second abutment plate 98 fix the hot-rolled steel during cutting.

[0054] The specific workflow is as follows: During operation, the tension detector 7568 detects the surface tension of the saw blade 7567. If the tension is small, the servo motor 7563 drives the reciprocating screw rod 7564 to rotate, thereby driving the movable clamping plate 7565 to move in the direction of the servo motor 7563, so that the tension of the saw blade 7567 increases. At the same time, the vibration detector 7571 detects the vibration frequency of the saw blade 7567. If the vibration frequency is high, the nozzle 78 on the water pump 74 sprays water to the overall reciprocating unit 75, and the impact force of the water causes the guide When waste chips fall off the rod 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 that contacts 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, thereby avoiding burrs at the bottom of the cut.

[0055] like Fig.14 As shown, the hot-rolled steel processing technology includes the following steps: S1: Prepare materials, inspect hot-rolled steel sections, and check whether all parts of the band saw are normal; S2: Clamp the workpiece, place the hot-rolled steel on the steel loading unit of the band saw, and clamp the steel firmly; S3: Sawing process, the driving unit drives the band saw unit to do reciprocating motion to saw the hot-rolled steel; S4: Quality inspection: after sawing, measure the size of the steel section and observe the roughness of the sawn surface.
