Description

Technical Field

[0001] The present invention relates to the technical field of flange processing, and specifically provides a blank cutting device for flange processing and an operation method thereof. Background Art

[0002] A flange, also known as a flange plate or a protruding flange, is a part used for connecting shafts to each other and is used for connecting pipe ends. There are also flanges used at the inlets and outlets of equipment for connecting two pieces of equipment; before processing, a flange blank is a relatively long cylindrical blank or a tubular blank.

[0003] For example, a cutting device for flange production with the publication number CN221064661U can drive a rotating roller to clamp the seamless steel pipe raw material for cutting a flange plate through cylinders one in the up, down, left, and right directions. Motors one at the upper and lower ends drive the rotating rollers at the upper and lower ends to rotate respectively to convey the raw material, and convey the seamless steel pipe to the lower end of the cutting blade. Cylinder three can drive a limiting rod to limit and support the front end of the seamless steel pipe raw material to ensure the stability of the seamless steel pipe raw material during cutting, thereby ensuring the dimensional accuracy of the cut flange plate. However, in actual use, most of the existing technologies can spray water to cool the cutting saw blade or the cutting position, but cannot cool the cutting end face of the blank. The cutting end face of the blank will have a lot of heat. And with the high-speed rotation of the cutting blade, it is difficult for the cooling water to act on the cutting end face of the cut blank. Moreover, when cutting a blank with a larger diameter, it is impossible to fully cool the deep part of the blank being cut. If the blank is not cooled in time, it will cause an increase in the internal thermal stress of the material, affecting the service life of the subsequent flange. And when cutting a blank made of some plastic materials, if it is not fully cooled, as the cutting depth increases, it is difficult for the cooling water to enter the inside of the cutting surface, and thus it is impossible to cool the cutting position in time. The chips generated by cutting melt at a high temperature, easily causing adhesion of the cutting end face and easily adhering to the cutting blade, having certain defects in use.

[0004] Therefore, we propose a blank cutting device for flange processing and an operation method thereof to solve the problems raised above. Summary of the Invention

[0022] By adopting the above technical solution, the blank can be rotated when cutting the blank.

[0023] A blank cutting device for flange processing and an operation method thereof, the specific operation method is as follows: Step 1: When the material blank is cut, the electric push rod is started to drive the movable plate to move downward, and the cutting blade on the cutting mechanism is driven to rotate by the motor. The movable plate can pull the pull rope to move while moving downward, and the pull rope can drive the first guide wheel and the second guide wheel to rotate after moving, so as to guide the movement of the pull rope, and then the two movable rods can be pulled to move by the connecting plate, so that the telescopic spring can be stretched, so that the support frame and the water spray pipe can be driven to move. The downward displacement of the cutting mechanism is consistent with the displacement of the water spray pipe, and the material blank can be cut by the cutting blade on the cutting mechanism. During the cutting process, water is pumped into the water tank through the water pump on the water pump, and then the water flows into the water spray pipe through the connecting hose. Water is sprayed through the water spray pipe to cool the cutting part of the material blank, and the cooling water can flow back into the water tank through the through groove and the filter. As the cutting work proceeds, the electric push rod will gradually drive the cutting mechanism to move downward. The cutting depth is continuously increased, and the water spray pipe can be continuously extended as the cutting depth increases, which can ensure that the blank can be fully cooled during the cutting process, and the cross-section of the water spray pipe is small, and the water flow rate of the water spray pipe is high. After the water flow impacts the blank, it can drive the connecting frame and the rotating shaft to rotate through the reaction force, which can drive the torsion spring to deform, and then the connecting frame can be reset under the action of the torsion spring, so that the water spray pipe can swing back and forth during the water spraying process to expand the water spraying range and fully cool the cutting part. The cooling component can be used to fully cool the cutting part of the blank when cutting the blank, and the position of the water spray pipe can be moved with the change of the cutting depth, ensuring that the cutting end face of the blank can be fully cooled, avoiding affecting the performance of the subsequent flange, avoiding the adhesion of debris, and saving the use of water flow, thereby improving practicality; Step 2: When cutting the blank, the blank is inserted into the cylinder, and then the electric cylinder can be started to retract it, so that the two rotating rings can be pulled by the rotating sleeve and the push rod to rotate outside the cylinder. As the rotating ring rotates, the movable frame can be pushed to slide on the limit frame through the cooperation of the movable groove and the column rod, so that the two sets of rollers can clamp and fix the blank together, and the blank is fixed by the friction force of the rollers. If the blank needs to be moved, the two rotating motors below can be started to rotate the two rollers below, so that the blank can be moved, which is convenient for continuous cutting of the blank, and then convenient for fixing the blank, and convenient for moving the blank to continuously cut the blank; Step 3: When cutting the blank, the driving motor can be started to drive the rotating gear to rotate. After the rotating gear rotates, it can drive the cylinder to rotate clockwise by meshing with the external gear ring outside the cylinder, so that the blank can be driven to rotate. Thus, during the cutting process, the blank can rotate, which can improve the cutting efficiency of the blank. And when cooling the cutting position of the blank, the position of the water spray pipe does not rotate. After the blank rotates clockwise, it can bring part of the cooling water to the cutting blade, and the cooling water can flow in the cutting gap, improving the uniformity of cooling and cooling the cutting blade, thereby extending the service life of the cutting blade. Compared with the prior art, the beneficial effects of the present invention are as follows: The blank cutting device for flange processing and its operation method enable sufficient cooling of the cutting part of the blank during cutting, and the position of the water spray pipe can move with the change of the cutting depth to ensure sufficient cooling of the cutting end face of the blank, avoiding affecting the subsequent use performance of the flange and preventing chip adhesion. Moreover, it can save the use of water flow, improving the practicability. 1. When cutting and processing the blank, start the electric push rod to drive the movable plate to move downward. The cutting mechanism drives the cutting blade to rotate through the motor. While the movable plate moves downward, it can pull the pull rope to move. After the pull rope moves, it can drive the first guide wheel and the second guide wheel to rotate to guide the movement of the pull rope. Then, it can drive two movable rods to move through the connecting plate, stretching the telescopic spring, so as to drive the support frame and the water spray pipe to move. The downward displacement of the cutting mechanism is the same as the displacement of the water spray pipe. The blank can be cut by the cutting blade on the cutting mechanism. During cutting, the water pump pumps water from the water tank through the water suction pipe, and then the water flows into the water spray pipe through the connecting hose. The water spray pipe sprays water to cool the cutting part of the blank, and the cooling water can flow back into the water tank through the through groove and the filter screen. As the cutting work progresses, the electric push rod will gradually drive the cutting mechanism to move downward, increasing the cutting depth continuously. The water spray pipe can extend continuously with the increase of the cutting depth, ensuring sufficient cooling during the cutting process of the blank. Moreover, the cross-section of the water spray pipe is small, and the water flow velocity sprayed by the water spray pipe is high. After the water flow impacts on the blank, it can drive the connecting frame and the rotating shaft to rotate through the reaction force, causing the torsion spring to deform. Then, under the action of the torsion spring, the connecting frame can be reset, enabling the water spray pipe to swing reciprocally during water spraying to expand the spraying range and fully cool the cutting part. Through the cooling component, sufficient cooling of the cutting part of the blank can be achieved during cutting, and the position of the water spray pipe can move with the change of the cutting depth to ensure sufficient cooling of the cutting end face of the blank, avoiding affecting the subsequent use performance of the flange and preventing chip adhesion. Moreover, it can save the use of water flow, improving the practicability. 2. When cutting the blank, insert the blank into the cylinder. Then, the electric cylinder can be activated to retract, so that the two rotating rings can be pulled to rotate outside the cylinder through the rotating sleeve and the push rod. As the rotating rings rotate, the movable frame can be pushed to slide on the limiting frame through the cooperation of the movable groove and the column rod, so that the two groups of rollers can jointly clamp and fix the blank. The blank is fixed by the friction force of the rollers. If the blank needs to be moved later, the two rotating motors below can be activated, so that the two rollers below rotate, and the blank can be moved, which is convenient for continuous cutting of the blank. Furthermore, it is convenient to fix the blank, and it is convenient to move the blank to continuously cut the blank; 3. When cutting the blank, the driving motor can be activated to drive the rotating gear to rotate. After the rotating gear rotates, it can drive the cylinder to rotate clockwise by engaging with the external gear ring outside the cylinder, so that the blank can be driven to rotate. Thus, during the cutting process, the blank can rotate, which can improve the cutting efficiency of the blank. Moreover, when cooling the cutting position of the blank, the position of the water spray pipe does not rotate. After the blank rotates clockwise, part of the cooling water can be brought to the cutting blade, and the cooling water can flow in the cutting gap, improving the uniformity of cooling and cooling the cutting blade, thus prolonging the service life of the cutting blade.

At the same time, torsion springs 203 are symmetrically sleeved on both sides of the connecting frame 204 on the outside of the rotating shaft 202. The two ends of the torsion spring 203 are fixedly connected to the connecting frame 204 and the movable rod 201 respectively; The mounting plate 205 is fixedly installed on one side of the connecting frame 204. A support frame 206 is fixedly installed on one side of the mounting plate 205. A water spray pipe 207 is fixedly installed inside the support frame 206; One end of the water spray pipe 207 is penetrated and connected with a connecting hose 208. A through groove 108 is penetrated and opened at the top of the workbench 1 below the cutting mechanism 107. A filter screen 109 is fixedly installed inside the through groove 108. A water tank 110 is fixedly installed below the through groove 108 at the bottom of the workbench 1. A water pump 209 is fixedly installed below one side of the water tank 110. The end of the connecting hose 208 away from the water spray pipe 207 passes through the workbench 1 and is penetrated and connected with the water supply end of the water pump 209. The water suction end of the water pump 209 is penetrated and connected with a water suction pipe 210. At the same time, the water suction pipe 210 is penetrated and connected with the water tank 110; One sides of the outside of the two movable rods 201 are both sleeved with telescopic springs 211. One end of the telescopic spring 211 is fixedly connected to the fixed frame 102. The other end of the telescopic spring 211 is fixedly installed with a fixed block 212. At the same time, the fixed block 212 is fixedly connected to the movable rod 201; One sides of the tops of the two movable rods 201 are fixedly installed with a connecting plate 213. A pull rope 214 is fixedly installed on one side of the connecting plate 213. The end of the pull rope 214 away from the connecting plate 213 is fixedly connected to the movable plate 105; An installation groove 215 is penetrated and opened above the two movable rods 201 on one side of the fixed frame 102. Support blocks 216 are symmetrically installed inside the installation groove 215. A first guide wheel 217 is rotatably connected between the two support blocks 216. Installation blocks 218 are symmetrically installed above the inside of the fixed frame 102. A second guide wheel 219 is fixedly installed between the two installation blocks 218. The pull rope 214 is rotatably connected to the first guide wheel 217 and the second guide wheel 219.

[0028] Example 1: As Figures 1-6As shown in the figure, when cutting the blank, start the electric push rod 103 to drive the movable plate 105 to move downward. The cutting mechanism 107 drives the cutting blade to rotate through a motor. While the movable plate 105 moves downward, it can pull the pull rope 214 to move. After the pull rope 214 moves, it can drive the first guide wheel 217 and the second guide wheel 219 to rotate, guiding the movement of the pull rope 214. Furthermore, it can pull the two movable rods 201 to move through the connecting plate 213, stretching the telescopic spring 211, so as to drive the support frame 206 and the water spray pipe 207 to move. The downward displacement of the cutting mechanism 107 is consistent with the displacement of the water spray pipe 207. The cutting blade on the cutting mechanism 107 can cut the blank. During the cutting process, the water pump 209 pumps water from the water tank 110 through the water suction pipe 210. Then the water flows into the water spray pipe 207 through the connecting hose 208, and the water spray pipe 207 sprays water to cool the cutting part of the blank. And the cooling water can flow back into the water tank 110 through the through groove 108 and the filter screen 109. As the cutting work progresses, the electric push rod 103 will gradually drive the cutting mechanism 107 to move downward, increasing the cutting depth continuously. The water spray pipe 207 can continuously extend as the cutting depth increases. After the cutting mechanism 107 completely cuts the blank, at this time, there is a certain interval between the water spray pipe 207 and the blade on the cutting mechanism 107, and the cutting mechanism 107 will not contact the water spray pipe 207, which can ensure sufficient cooling during the blank cutting process. And the cross-section of the water spray pipe 207 is small, and the water flow rate sprayed by the water spray pipe 207 is high. After the water flow impacts on the blank, it can drive the connecting frame 204 and the rotating shaft 202 to rotate through the reaction force, and can drive the torsion spring 203 to deform. After the water spray pipe 207 moves away from the blank, the impact force decreases. Then under the action of the torsion spring 203, the connecting frame 204 can be reset, so that the water spray pipe 207 can swing reciprocally during the water spraying process to expand the water spraying range and fully cool the cutting part. Through the cooling component 2, when cutting the blank, the cutting part of the blank can be fully cooled, and the position of the water spray pipe 207 can move with the change of the cutting depth, ensuring that the cutting end face of the blank can be fully cooled, avoiding affecting the use performance of the subsequent flange, and avoiding debris adhesion, and can save the use of water flow, improving the practicability.

[0029] The fixing component 3 is arranged on one side of the top of the workbench 1 close to the fixing frame 102; The fixing component 3 includes a positioning frame 301 fixedly installed on the top of the workbench 1 on one side of the fixing frame 102. The inside of the positioning frame 301 is rotatably connected with a cylinder body 302. Two groups of limiting frames 303 are symmetrically installed on the outside of the cylinder body 302. At the same time, two movable frames 304 are slidably connected inside the two groups of limiting frames 303. Moreover, one side of the movable frame 304 is fixedly installed with a U-shaped frame 305, and a roller 306 is rotatably connected inside the U-shaped frame 305; Rotating motors 307 are fixedly installed on one side of each of the two lower U-shaped frames 305, and the output ends of the rotating motors 307 pass through the U-shaped frames 305 and are fixedly connected to the roller wheels 306; Rotating rings 308 are symmetrically and rotatably connected to both sides of the outer part of the cylinder body 302 and located outside the two limiting frames 303. One side of each rotating ring 308 is symmetrically provided with movable slots 310. Column rods 309 are fixedly installed on one side of the two limiting frames 303 close to the positioning frame 301. The column rods 309 are slidably connected to the movable slots 310. A push rod 311 is fixedly installed on one side between the two rotating rings 308. An electric cylinder 312 is hinged to one side of the outer part of the cylinder body 302 close to the positioning frame 301. The movable end of the electric cylinder 312 is fixedly installed with a rotating sleeve 313, and the rotating sleeve 313 is rotatably connected to the push rod 311.

[0030] Example 2: As Figures 1-2 and Figures 8-9 shown, when cutting the blank, the blank is inserted into the cylinder body 302. Then, the electric cylinder 312 can be started to retract, so that the two rotating rings 308 can be pulled to rotate outside the cylinder body 302 through the cooperation of the rotating sleeve 313 and the push rod 311. As the rotating rings 308 rotate, the movable frame 304 can be pushed to slide on the limiting frame 303 through the cooperation of the movable slot 310 and the column rod 309, so that the two roller wheels 306 can jointly clamp and fix the blank. The blank is fixed by the frictional force of the roller wheels 306. If the blank needs to be moved later, the two lower rotating motors 307 can be started to make the two lower roller wheels 306 rotate, so that the blank can be moved, which is convenient for continuous cutting of the blank. Furthermore, it is convenient to fix the blank and move the blank to continuously cut the blank.

[0031] An external gear ring 314 is fixedly installed on one side of the outer part of the cylinder body 302 and located on the side of the electric cylinder 312. A driving motor 315 is fixedly installed above one side of the positioning frame 301. The output end of the driving motor 315 is fixedly installed with a rotating gear 316, and the rotating gear 316 is meshed with the external gear ring 314.

[0032] Example 3: As Figures 8-9As shown in the figure, when cutting the blank, the driving motor 315 can be started to drive the rotating gear 316 to rotate. After the rotating gear 316 rotates, it can drive the cylinder body 302 to rotate clockwise by engaging with the external gear ring 314 outside the cylinder body 302, so as to drive the blank to rotate. Thus, during the cutting process, the blank can rotate, which can improve the cutting efficiency of the blank. And when cooling the cutting position of the blank, the position of the water spray pipe 207 does not rotate. After the blank rotates clockwise, part of the cooling water can be brought to the cutting blade, and the cooling water can flow in the cutting gap, improving the uniformity of cooling and cooling the cutting blade, thus extending the service life of the cutting blade.

[0033] Working principle: When using the blank cutting device for flange processing, first, according to Figures 1-9 As shown in the figure, when cutting and processing the blank, the electric push rod 103 is started to drive the movable plate 105 to move downward. The cutting blade on the cutting mechanism 107 is driven to rotate by a motor. While the movable plate 105 moves downward, it can pull the pull rope 214 to move. After the pull rope 214 moves, it can drive the first guide wheel 217 and the second guide wheel 219 to rotate, guiding the movement of the pull rope 214. Then, the two movable rods 201 can be pulled through the connecting plate 213, stretching the telescopic spring 211, so as to drive the support frame 206 and the water spray pipe 207 to move. The downward displacement of the cutting mechanism 107 is the same as the displacement of the water spray pipe 207. The blank can be cut by the cutting blade on the cutting mechanism 107. During the cutting process, water is pumped from the water tank 110 through the water suction pipe 210 on the water pump 209. Then the water flows into the water spray pipe 207 through the connecting hose 208, and the cutting part of the blank is cooled by spraying water through the water spray pipe 207. And the cooling water can flow back into the water tank 110 through the through groove 108 and the filter screen 109. As the cutting work progresses, the electric push rod 103 will gradually drive the cutting mechanism 107 to move downward, increasing the cutting depth continuously. The water spray pipe 207 can extend continuously as the cutting depth increases, ensuring sufficient cooling during the blank cutting process. And the cross-section of the water spray pipe 207 is small, and the water flow rate sprayed by the water spray pipe 207 is high. After the water flow impacts on the blank, it can drive the connecting frame 204 and the rotating shaft 202 to rotate through the reaction force, driving the torsion spring 203 to deform. Then, under the action of the torsion spring 203, the connecting frame 204 can be reset, so that the water spray pipe 207 can swing back and forth during water spraying to expand the spraying range and fully cool the cutting part. When cutting a billet, the billet is inserted into the cylinder body 302. After that, the electric cylinder 312 can be started to retract, so that the two rotating rings 308 can be pulled to rotate outside the cylinder body 302 through the rotating sleeve 313 and the push rod 311. As the rotating ring 308 rotates, the movable frame 304 can be pushed to slide on the limiting frame 303 through the cooperation of the movable groove 310 and the column rod 309, so that the two groups of roller wheels 306 can jointly clamp and fix the billet. The billet is fixed by the frictional force of the roller wheels 306. After that, if the billet needs to be moved, the two rotating motors 307 below can be started to make the two roller wheels 306 below rotate, so that the billet can be moved, which is convenient for continuous cutting of the billet. Furthermore, it is convenient to fix the billet and move the billet to continuously cut the billet. When cutting the billet, the driving motor 315 can be started to drive the rotating gear 316 to rotate. After the rotating gear 316 rotates, it can drive the cylinder body 302 to rotate clockwise by meshing with the external gear ring 314 outside the cylinder body 302, so that the billet can be driven to rotate. Thus, the billet can rotate during the cutting process, which can improve the cutting efficiency of the billet. Moreover, when cooling the cutting position of the billet, the position of the water spray pipe 207 does not rotate. After the billet rotates clockwise, part of the cooling water can be brought to the cutting blade, and the cooling water can flow in the cutting gap, improving the uniformity of cooling and cooling the cutting blade, thus prolonging the service life of the cutting blade.

10. An operating method of a blank cutting device for flange processing, using a blank cutting device for flange processing as described in claim 9, characterized in that, The specific operation method is as follows: Step 1: When cutting a billet, start the electric push rod (103) to drive the movable plate (105) to move downward. On the cutting mechanism (107), the cutting blade is driven to rotate by a motor. While the movable plate (105) moves downward, it can pull the pull rope (214) to move. After the pull rope (214) moves, it can drive the first guide wheel (217) and the second guide wheel (219) to rotate, guiding the movement of the pull rope (214). Then, it can pull the two movable rods (201) to move through the connecting plate (213), stretching the telescopic spring (211), so as to drive the support frame (206) and the water spray pipe (207) to move. The downward displacement of the cutting mechanism (107) is consistent with the displacement of the water spray pipe (207). The billet can be cut by the cutting blade on the cutting mechanism (107). During the cutting process, the water tank (110) is pumped through the water suction pipe (210) on the water pump (209). Then, the water flows into the water spray pipe (207) through the connecting hose (208). The water spray pipe (207) sprays water to cool the cutting part of the billet. And the cooling water can flow back into the water tank (110) through the through groove (108) and the filter screen (109). As the cutting work progresses, the electric push rod (103) will gradually drive the cutting mechanism (107) to move downward, increasing the cutting depth continuously. The water spray pipe (207) can continuously extend as the cutting depth increases, ensuring that the billet can be fully cooled during the cutting process. Moreover, the cross-section of the water spray pipe (207) is small, and the water flow velocity sprayed by the water spray pipe (207) is high. After the water flow impacts on the billet, it can drive the connecting frame (204) and the rotating shaft (202) to rotate through the reaction force, driving the torsion spring (203) to deform. Then, under the action of the torsion spring (203), the connecting frame (204) can be reset, enabling the water spray pipe (207) to swing reciprocally during water spraying to expand the water spraying range and fully cool the cutting part. Through the cooling component (2), when cutting the billet, the cutting part of the billet can be fully cooled. And the position of the water spray pipe (207) can move with the change of the cutting depth, ensuring that the cutting end face of the billet can be fully cooled, avoiding affecting the use performance of the subsequent flange, and preventing chip adhesion. Also, it can save the use of water flow, improving the practicability; Step Two: When cutting the blank, the blank is inserted into the cylinder body (302). After that, the electric cylinder (312) can be started to retract, so that the two rotating rings (308) can be pulled to rotate outside the cylinder body (302) through the rotating sleeve (313) and the push rod (311). As the rotating rings (308) rotate, the movable frame (304) can be pushed to slide on the limiting frame (303) through the cooperation of the movable groove (310) and the column rod (309), so that the two groups of rollers (306) can jointly clamp and fix the blank. The blank is fixed by the frictional force of the rollers (306). If the blank needs to be moved later, the two rotating motors (307) below can be started, so that the two rollers (306) below rotate, and the blank can be moved, which is convenient for continuous cutting of the blank. Furthermore, it is convenient to fix the blank, and it is convenient to move the blank to continuously cut the blank; Step Three: When cutting the blank, the driving motor (315) can be started to drive the rotating gear (316) to rotate. After the rotating gear (316) rotates, it can drive the cylinder body (302) to rotate clockwise by meshing with the external gear ring (314) outside the cylinder body (302), so that the blank can be driven to rotate. Therefore, the blank can rotate during the cutting process, which can improve the cutting efficiency of the blank. Moreover, when cooling the cutting position of the blank, the position of the water spray pipe (207) does not rotate. After the blank rotates clockwise, part of the cooling water can be brought to the cutting blade, and the cooling water can flow in the cutting gap, improving the uniformity of cooling and cooling the cutting blade, thus prolonging the service life of the cutting blade.
