Description

Technical Field

[0001] The utility model relates to the field of steel rolling production, in particular to a rolled piece segmented hot sawing machine used in steel rolling production. Background Art

[0002] The hot sawing machine for steel production is an important auxiliary equipment in hot rolling workshops. It is widely used in metallurgical plants for steel sections, especially in the rolling production line of special-section steel sections. It is usually installed on the production line behind the rolling mill. Its main function is to cut the heads, tails and lengths of the rolled products rolled out of the rolling mill. The hot sawing machine has the advantages of simple equipment, light weight and high production efficiency. The cut surface is flat and the cut edge of the rolled product is high in precision.

[0003] Chinese patent publication number CN116475491B discloses a hot saw machine, including fan blades, an air distribution duct fixed on the inner side wall of the casing to guide the wind to move toward the inner top wall of the casing, a gap is left between the air distribution duct and the inner top wall of the casing, and the inner top wall of the casing is fixed with an air guide plate 1 to guide the wind downward. On the one hand, the rotating shaft drives the saw blade to rotate and cut, and on the other hand, it drives the fan blades to rotate and blow. The generated wind moves downward under the guidance of the air distribution duct, the inner top wall of the casing and the air guide plate 1, thereby blowing the waste water to be discharged faster and drying the internal environment of the casing, thereby reducing the residue inside the casing and causing rust.

[0004] During the cutting process, the hot saw machine of the above patent can only perform stable rolled steel cutting after being clamped by a splint. The rolled steel is in a high temperature state during the cutting process. After the equipment repeatedly cuts and is repeatedly clamped by the splint, contact with the high-temperature rolled steel will cause damage to the splint, affecting the service life of the equipment and requiring frequent replacement of the splint. Utility Model Content

[0005] The purpose of the present utility model is to provide a hot sawing machine for segmented rolled pieces for steel rolling production. The rotation of the connecting shaft drives a pair of clamping plates to rotate and replace the clamping plates close to the pump. After the pump is started, the extension and retraction of the first telescopic rod can push the transmission pipe to fit the connecting pipe, so that the liquid extracted by the pump is transmitted to the inside of the clamping plate and the clamping plate is efficiently cooled. The replaced clamping plate is cooled independently to avoid damage to a single clamping plate caused by repeated contact with high-temperature materials, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hot sawing machine for rolled pieces used in steel rolling production, comprising a saw blade and conveying rollers at both ends, first brackets fixed by bolts are provided on both sides of the outside of the conveying rollers, a pair of second brackets are horizontally provided in the middle of the upper ends of the two first brackets, a connecting shaft is provided between the pair of second brackets, a first telescopic rod is provided at one end of the connecting shaft, a pump is provided on one side of the outside of the first telescopic rod, liquid is extracted by the pump and transmitted to the inside of the clamping piece, the replaced clamping piece can be actively cooled so that the replaced clamping piece can be subsequently brought into contact with high-temperature materials, thereby avoiding repeated contact of a single clamping piece with high-temperature materials.

[0007] Preferably, clamping plates are provided on both sides of the connecting shaft, a transmission tube is sealedly provided at one end of the pump discharge outlet facing the clamping plate, and a connecting frame welded and fixed to the telescopic position of the first telescopic rod is provided on one side of the outside of the transmission tube. The connecting frame can be pushed by the extension and contraction of the first telescopic rod, and the extension and contraction of the connecting frame can drive the transmission tube to move, so that the liquid transmitted by the transmission tube can flow into the contacted clamping plate.

[0008] Preferably, one end of the clamping piece is sealed with a first one-way valve, one end of the first one-way valve is sealed with a connecting pipe, and the side of the clamping piece facing the first bracket is sealed with a second one-way valve. The liquid transmitted by the transmission pipe is connected by the connecting pipe and passes through the first one-way valve and flows into the interior of the clamping piece. The liquid flowing into the interior of the clamping piece will be discharged from the position of the second one-way valve. The liquid flows in the clamping piece and can actively cool the clamping piece.

[0009] Preferably, a water tank is welded to the lower end of the first bracket, and the lower end of the water tank is sealed with the water pumping position of the pump. The liquid discharged from the second one-way valve position will flow into the water tank, and the liquid flowing into the water tank can also be repeatedly extracted by the pump.

[0010] Preferably, a heat sink is welded inside the clamping plate. When the high-temperature material contacts the clamping plate, the heat is transferred to the inside of the heat sink. The heat sink can improve the contact surface between the heat and the liquid, making it easier for the liquid to flow into the clamping plate and discharge the heat.

[0011] Preferably, a rubber ring fixed by glue is provided around the side of the connecting tube facing the transmission tube. The transmission tube can contact the connecting tube after the first telescopic rod is extended and retracted. The rubber ring fills the gap between the connecting tube and the transmission tube to prevent liquid from leaking out.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] When the saw blade of the utility model rotates and presses down to complete the cutting, it is clamped by the clamping piece and after completing the cutting, the cut rolled steel is pushed to move horizontally by the rotation of the transmission roller. At the same time, the connecting shaft is driven by the motor and rotates under the support of the second bracket. The rotation of the connecting shaft will replace the clamping piece, and the replaced clamping piece will move and approach the pump. The pump can extract the liquid inside the water tank and transport it to the inside of the clamping piece after being transmitted through the transmission pipe. The liquid flows from the first one-way valve position and is finally discharged from the second one-way valve position. The liquid flows inside the clamping piece and can contact the heat sink welded and fixed to the clamping piece. The liquid can efficiently cool the clamping piece. When clamping the gap between the high-temperature rolled steel, the clamping piece used for clamping is replaced, and the replaced clamping piece is actively cooled to avoid damage to the clamping piece due to repeated contact with the high-temperature rolled steel for a long time.

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] Example 1

[0021] like Figure 1 As shown, the hot sawing machine for rolling steel production of this embodiment includes a saw blade 1, and transmission rollers 2 are provided at both ends of the saw blade 1. The transmission of the transmission rollers 2 can drive the rolled steel to be cut at the upper end to move horizontally. The horizontal movement of the rolled steel can adjust the cutting position of the saw blade 1.

[0022] Wherein, first brackets 3 are provided on both sides of the outside of the conveying roller 2, and the first brackets 3 are fixedly connected to both sides of the outside of the conveying roller 2 by bolts, such as Figure 1 and Figure 2As shown, a pair of second brackets 7 are horizontally arranged in the middle of the upper ends of the two first brackets 3, and a connecting shaft 15 is provided between the pair of second brackets 7. The outer portion of the connecting shaft 15 is rotatably connected to the inner portion of the two second brackets 7, and a clamping piece 9 is provided on both sides of the connecting shaft 15. The clamping piece 9 can be adjusted after the rotation and transmission of the connecting shaft 15. Alternating the use of the clamping piece 9 can prevent the clamping piece 9 from being continuously in contact with high-temperature materials and being damaged after continuous use.

[0023] In addition, if Figure 2 As shown, a second telescopic rod 8 is provided between the clamping piece 9 and the connecting shaft 15, and both ends of the second telescopic rod 8 are fixedly connected to the clamping piece 9 and the connecting shaft 15 by bolts. After the connection shaft 15 is driven, the second telescopic rod 8 can drive the clamping piece 9 to adjust its position, and the clamping piece 9 can be pushed by the extension and contraction of the second telescopic rod 8, and the clamping piece 9 can be pushed to clamp the rolled steel;

[0024] In order to facilitate the fixing of the rotating connecting shaft 15, as shown in FIG. Figure 2 and Figure 4 As shown, a first telescopic rod 6 is provided at one end of the connecting shaft 15, a pump 5 is provided on one side outside the first telescopic rod 6, a transmission pipe 10 is provided on one end of the pump 5 discharge port facing the clamping piece 9, and the transmission pipe 10 is sealedly connected to the pump 5, a connecting frame 11 is provided on one side outside the transmission pipe 10, and the connecting frame 11 is welded and fixed to the telescopic position of the first telescopic rod 6. The extension and contraction of the first telescopic rod 6 can be achieved by the connecting frame 11 contacting the connecting shaft 15, and the connecting frame 11 can also be achieved by the connecting frame 11 being in contact with the connecting pipe 12;

[0025] Among them, one end of the clamping piece 9 is provided with a first one-way valve 13, and one end of the first one-way valve 13 is provided with a connecting pipe 12, and the connecting pipe 12, the first one-way valve 13 and the clamping piece 9 are sealed and connected in sequence, such as Figure 2 and Figure 3 As shown, the second one-way valve 14 is sealed on one side of the clamping piece 9 facing the first bracket 3. After the clamping piece 9 rotates, the clamping piece 9 can drive the second one-way valve 14 toward the first bracket 3, so that the liquid can flow into the clamping piece 9 after being extracted by the pump 5, along the transmission pipe 10, the connecting pipe 12 and the first one-way valve 13. Finally, the liquid inside the clamping piece 9 can be discharged through the second one-way valve 14:

[0026] In addition, a water tank 4 is provided at the lower end of the first bracket 3, and the water tank 4 is welded and fixed to the first bracket 3. The lower end of the interior of the water tank 4 is sealedly connected to the pumping position of the pump 5. After the liquid inside the water tank 4 is pumped out by the pump 5 and transferred to the inside of the clamping piece 9, it will fall through the position of the second one-way valve 14 and be pumped out again, realizing the circulation of the liquid;

[0027] In order to improve the heat dissipation effect of the clamping piece 9, as Figure 2 and Figure 3 As shown, a heat sink 16 is provided inside the clamping piece 9, and the heat sink 16 is welded to the clamping piece 9. When the clamping piece 9 clamps and contacts the high-temperature rolled steel, the temperature is transferred to the clamping piece 9 and then to the heat sink 16 inside the clamping piece 9. After the liquid flows into the clamping piece 9, it contacts the heat sink 16 that transfers heat. The heat sink 16 can increase the heat dissipation area, increase the area of the liquid contacting the heat-generating position, and improve the heat dissipation efficiency of the clamping piece 9.

[0028] Example 2

[0029] In order to improve the fit between the transmission tube 10 and the connecting tube 12 and avoid the situation where, after the first telescopic rod 6 is extended and retracted, the gap between the transmission tube 10 and the connecting tube 12 causes the liquid discharged from the transmission tube 10 to flow out from the gap between the transmission tube 10 and the connecting tube 12, a rubber ring 17 is provided around the side of the connecting tube 12 facing the transmission tube 10, and the rubber ring 17 is fixed to the connecting tube 12 by glue.

[0030] Working principle: When the device is used to clamp and cut the high-temperature rolled steel, the saw blade 1 rotates and cuts the rolled steel on the upper end of the conveyor roller 2. At the same time, the second telescopic rod 8 near the two sides of the conveyor roller 2 is started. The corresponding extension and contraction of the second telescopic rod 8 can push the clamping piece 9. The clamping of the two clamping pieces 9 can fix the rolled steel to be cut on the upper end of the conveyor roller 2. After the cutting and clamping are completed in a single time, after the conveyor roller 2 rotates and drives the rolled steel to move horizontally, the pump 5 can drive the clamping piece 9 near the conveyor roller 2 and the spare clamping piece 9 distributed in a mirror image after the output of the motor, replacing the two clamping pieces. After the plate 9 is clamped, the first telescopic rod 6 is started. The extension and contraction of the first telescopic rod 6 can push the connecting frame 11. The lateral movement of the connecting frame 11 can simultaneously fit a section of the connecting shaft 15, and the connecting frame 11 can drive the transmission pipe 10 to fit closely to the connecting pipe 12 close to the pump 5. The pump 5 is started and the pump 5 can extract the liquid inside the water tank 4. The liquid is transmitted to the inside of the connecting pipe 12 through the transmission pipe 10. The liquid inside the connecting pipe 12 flows into the inside of the clamping plate 9 through the first one-way valve 13. The liquid inside the clamping plate 9 contacts the heat sink 16 and is discharged from the second one-way valve 14. The discharged liquid is stored in the water tank 4.
