Description

Technical Field

[0001] This invention relates to the field of flange processing technology, specifically to a blank cutting device for flange processing and its operating method. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts to each other. It is used for connecting pipe ends, and also for connecting two pieces of equipment at the inlet and outlet. Before processing, the flange blank is a long cylindrical or tubular blank.

[0003] For example, a flange production cutting device (announcement number CN221064661U) uses cylinders (one on each side) to drive rotating rollers to clamp the seamless steel pipe raw material for cutting the flange. Motors at the top and bottom drive the rotating rollers to convey the raw material, transferring the seamless steel pipe to the lower end of the cutting blade. Cylinder three drives a limiting rod to limit and support the front end of the seamless steel pipe raw material, ensuring its stability during cutting and thus guaranteeing the dimensional accuracy of the cut flange. However, in practical use, most 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... It generates a lot of heat, and with the high-speed rotation of the cutting blade, it is difficult for cooling water to reach the cutting end face of the blank. When cutting blanks with a large diameter, it is not possible to fully cool the depth of the cut. If the blank is not cooled in time, it will cause the internal thermal stress of the material to increase, affecting the service life of the flange. Furthermore, if some blanks made of plastic are not sufficiently cooled, as the cutting depth increases, it is difficult for cooling water to enter the cutting surface, thus failing to cool the cutting position in time. The debris generated during cutting melts at high temperature, which can easily cause the cutting end face to stick together and adhere to the cutting blade, resulting in certain defects in use.

[0004] Therefore, we propose a blank cutting device and its operation method for flange processing in order to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a blank cutting device and its operating method for flange processing, so as to solve the problems mentioned in the background art, such as the inability to cool the cutting end face of the blank, the blank cutting end face having a lot of heat, and the difficulty of cooling water acting on the cutting end face of the blank as the cutting blade rotates at high speed, and the inability to fully cool the deep cutting depth of the blank when cutting blanks with a large diameter.

[0028] By adopting the above technical solution, the blank can be rotated during the cutting process.

[0029] A blank cutting device for flange processing and its operating method are disclosed below.

[0030] Step 1:

[0031] When cutting the blank, the electric push rod is activated, causing the movable plate to move downwards. The cutting mechanism, driven by a motor, rotates the cutting blade. As the movable plate moves downwards, it pulls a rope, which in turn rotates the first and second guide wheels, guiding the rope's movement. This, in turn, pulls two movable rods via a connecting plate, stretching the springs and moving the support frame and water spray pipe. The downward displacement of the cutting mechanism matches the displacement of the water spray pipe, allowing the cutting blade to cut the blank. During cutting, water is pumped from the water tank through a water pump pipe. The water then flows through a connecting hose into the water spray pipe, cooling the cut area of ​​the blank. The cooling water can then flow back into the water tank through a channel and filter. As the cutting process continues, the electric push rod gradually lowers the cutting mechanism, causing... As the cutting depth increases, the water spray pipe can extend further, ensuring sufficient cooling of the blank during cutting. The small cross-section of the water spray pipe allows for high water velocity; the water impact on the blank triggers a reaction force that rotates the connecting frame and rotating shaft, causing the torsion spring to deform. The torsion spring then resets the connecting frame, allowing the water spray pipe to oscillate and expand the spray range, effectively cooling the cut area. The cooling components ensure sufficient cooling of the blank's cut surface during cutting, and the water spray pipe's position can move with the cutting depth to ensure adequate cooling of the cut end face, preventing impact on the subsequent flange performance, avoiding debris adhesion, saving water, and improving practicality.

[0032] Step Two:

[0033] When cutting the blank, the blank is inserted into the cylinder. Then, the electric cylinder can be activated to retract it, which allows the rotating sleeve and push rod to pull two rotating rings to rotate outside the cylinder. As the rotating rings rotate, the movable frame slides on the limit frame through the cooperation of the movable groove and the column rod. This allows the two sets of rollers to clamp and fix the blank together. The friction of the rollers fixes the blank. If the blank needs to be moved, the two rotating motors below can be activated to rotate the two rollers below, allowing the blank to be moved. This facilitates continuous cutting of the blank, and also makes it easier to fix and move the blank for continuous cutting.

[0034] Step 3:

[0035] When cutting the blank, the drive motor can be started to rotate the rotating gear. The rotating gear, after engaging with the external gear ring on the outside of the cylinder, drives the cylinder to rotate clockwise, thus rotating the blank. This rotation of the blank during cutting improves cutting efficiency. Furthermore, when cooling the cutting area, the water spray pipe does not rotate. The clockwise rotation of the blank carries some cooling water to the cutting blade, and the cooling water flows within the cutting kerf, improving cooling uniformity and further cooling the cutting blade, extending its service life.

[0036] Compared with the prior art, the beneficial effects of the present invention are: the blank cutting device and its operation method for flange processing enable sufficient cooling of the blank cutting area during blank cutting, and the position of the water spray pipe can be moved with the change of cutting depth to ensure sufficient cooling of the cut end face of the blank, avoid affecting the subsequent flange performance, avoid chip adhesion, save water usage, and improve practicality.

[0037] 1. When cutting the blank, the electric push rod is activated, causing the movable plate to move downwards. The cutting mechanism, driven by a motor, rotates the cutting blade. Simultaneously, the movable plate pulls a rope, which in turn rotates the first and second guide wheels, guiding the rope's movement. This, in turn, pulls two movable rods via a connecting plate, stretching the springs and moving the support frame and water spray pipe. The downward displacement of the cutting mechanism matches the displacement of the water spray pipe, allowing the cutting blade to cut the blank. During cutting, water is pumped from the water tank via a pump pipe, then flows through a connecting hose into the water spray pipe. The water sprayed through the spray pipe cools the cut area of ​​the blank, and the cooling water flows back into the water tank through a channel and filter. As the cutting process continues, the electric push rod gradually lowers the cutting mechanism. This design allows for continuous increases in cutting depth, with the water spray pipe extending further into the material. This ensures adequate cooling of the blank during cutting. The small cross-section of the water spray pipe allows for high water velocity. The water impact on the blank triggers a reaction force that rotates the connecting frame and rotating shaft, causing the torsion spring to deform. The torsion spring then resets the connecting frame, allowing the water spray pipe to oscillate and expand the spray range, effectively cooling the cut area. The cooling components ensure sufficient cooling of the cut area during blank cutting. Furthermore, the water spray pipe's position can move with the cutting depth to ensure adequate cooling of the cut end face, preventing impact on the subsequent flange performance, avoiding debris adhesion, saving water, and improving practicality.

[0038] 2. When cutting the blank, the blank is inserted into the cylinder. Then, the electric cylinder can be activated to retract it, so that the rotating sleeve and push rod can pull the two rotating rings to rotate outside the cylinder. As the rotating rings rotate, 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. The friction of the rollers fixes the blank. If the blank needs to be moved, the two rotating motors below can be activated to rotate the two rollers below, so that the blank can be moved, which facilitates continuous cutting of the blank. This makes it easier to fix the blank and move the blank for continuous cutting.

[0039] 3. When cutting the blank, the drive motor can be started to drive the rotating gear to rotate. After the rotating gear rotates, it can drive the cylinder to rotate clockwise through the external gear ring on the outside of the cylinder, so that the blank can rotate. Thus, the blank can rotate during the cutting process, which can improve the cutting efficiency of the blank. When cooling the cutting position of the blank, the water spray pipe will not rotate. After the blank rotates clockwise, some of the cooling water can be carried 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.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Please see Figures 1-9 The present invention provides a technical solution: a blank cutting device for flange processing, including a workbench 1, support legs 101 symmetrically installed at the bottom of the workbench 1, and a fixed frame 102 fixedly installed at the top of the workbench 1, and an electric push rod 103 fixedly installed at the top of the fixed frame 102.

[0052] Also includes:

[0053] Guide rods 104 are symmetrically slidably connected to the inside of the fixed frame 102. The movable end of the electric push rod 103 passes through the fixed frame 102 and is fixedly installed with a movable plate 105. The bottom ends of the two guide rods 104 are fixedly connected to the movable plate 105. Mounting brackets 106 are symmetrically installed at the bottom of the movable plate 105. At the same time, a cutting mechanism 107 is provided below the two mounting brackets 106.

[0054] Cooling component 2 is disposed inside the fixed frame 102, and cooling component 2 includes a movable rod 201;

[0055] Movable rods 201 are symmetrically slidably connected to one side of fixed frame 102. A rotating shaft 202 is rotatably connected between the two movable rods 201 on one side. A connecting frame 204 is fixedly installed on the outside of the rotating shaft 202. Meanwhile, 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 springs 203 are fixedly connected to the connecting frame 204 and the movable rods 201 respectively.

[0056] Mounting plate 205 is fixedly installed on one side of connecting frame 204. Support frame 206 is fixedly installed on one side of mounting plate 205, and water spray pipe 207 is fixedly installed inside support frame 206.

[0057] One end of the water spray pipe 207 is connected to a connecting hose 208, and a through groove 108 is opened on 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 on the bottom of the workbench 1 below the through groove 108. A water pump 209 is fixedly installed on one side of the lower part 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 connected to the water delivery end of the water pump 209. A water pump 210 is connected to the water pump 209's suction end, and the water pump 210 is connected to the water tank 110.

[0058] Each of the two movable rods 201 is fitted with a telescopic spring 211 on one side of its outer side. One end of the telescopic spring 211 is fixedly connected to the fixed frame 102, and the other end of the telescopic spring 211 is fixedly installed with a fixing block 212. At the same time, the fixing block 212 is fixedly connected to the movable rod 201.

[0059] A connecting plate 213 is fixedly installed on one side of the top of the two movable rods 201, and a pull rope 214 is fixedly installed on one side of the connecting plate 213, and the end of the pull rope 214 away from the connecting plate 213 is fixedly connected to the movable plate 105.

[0060] A mounting groove 215 is provided on one side of the fixed frame 102 above the two movable rods 201. Support blocks 216 are symmetrically installed on the inner side of the mounting groove 215. A first guide wheel 217 is rotatably connected between the two support blocks 216. At the same time, mounting blocks 218 are symmetrically installed on the upper inner side of the fixed frame 102. A second guide wheel 219 is fixedly installed between the two mounting blocks 218. The pull rope 214 is rotatably connected to the first guide wheel 217 and the second guide wheel 219.

[0061] Example 1: As Figures 1-6As shown, when cutting the blank, the electric push rod 103 is activated to move the movable plate 105 downward. The cutting mechanism 107 drives the cutting blade to rotate via a motor. Simultaneously, the movable plate 105 pulls the pull rope 214, which in turn rotates the first guide wheel 217 and the second guide wheel 219, guiding the movement of the pull rope 214. This, in turn, allows the connecting plate 213 to pull the two movable rods 201, stretching the telescopic spring 211. This, in turn, moves the support frame 206 and the water spray pipe 207. The lowering of the cutting mechanism 107... The displacement is consistent with the displacement of the water spray pipe 207. The cutting mechanism 107 can cut the blank through the cutting blade. During the cutting process, water is pumped into the water tank 110 through the water pump 209's water suction pipe 210. The water then flows into the water spray pipe 207 through the connecting hose 208. The water sprayed through the water spray pipe 207 cools the cut area of ​​the blank. 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, so that the cutting depth will continuously increase. 07 can extend continuously as the cutting depth increases. After the cutting mechanism 107 completely cuts the blank, there is a certain gap between the water spray pipe 207 and the blade on the cutting mechanism 107. The cutting mechanism 107 will not contact the water spray pipe 207, which can ensure that the blank can be sufficiently cooled during the cutting process. Moreover, the cross-section of the water spray pipe 207 is small, and the water sprayed from the water spray pipe 207 has a high flow rate. After the water flow impacts the blank, it can drive the connecting frame 204 and the rotating shaft 202 to rotate through the reaction force, which can drive the torsion spring 203 to deform. The water spray pipe 207 moves away from the blank. After the impact force on the blank is reduced, the connecting frame 204 can be reset under the action of the torsion spring 203, so that the water spray pipe 207 can swing back and forth during the water spraying process to expand the water spraying range and fully cool the cutting area. The cooling component 2 can fully cool the cutting area of ​​the blank when cutting it, and the position of the water spray pipe 207 can move with the change of cutting depth to ensure that the cutting end face of the blank can be fully cooled, so as to avoid affecting the performance of the flange afterward, avoid the adhesion of debris, save water usage, and improve practicality.

[0062] The fixing component 3 is located on the top of the workbench 1 on the side near the fixing frame 102;

[0063] 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 positioning frame 301 is rotatably connected to the cylinder 302. Two sets of limiting frames 303 are symmetrically installed on the outside of the cylinder 302. The two sets of limiting frames 303 are slidably connected to the inside of each set of limiting frames 304. A U-shaped frame 305 is fixedly installed on one side of the movable frame 304. A roller 306 is rotatably connected to the inside of the U-shaped frame 305.

[0064] A rotating motor 307 is fixedly installed on one side of each of the two lower U-shaped frames 305, and the output end of the rotating motor 307 passes through the U-shaped frame 305 and is fixedly connected to the roller 306.

[0065] The outer side of the cylinder 302 is symmetrically connected to two sets of limiting frames 303 on both sides by rotating rings 308. One side of the rotating rings 308 is symmetrically provided with movable grooves 310. The two sets of limiting frames 303 are fixedly installed with column rods 309 on the side near the positioning frame 301. The column rods 309 are slidably connected to the movable grooves 310. A push rod 311 is fixedly installed on one side between the two rotating rings 308. An electric cylinder 312 is hinged to the outer side of the cylinder 302 near the positioning frame 301. A rotating sleeve 313 is fixedly installed on the movable end of the electric cylinder 312. The rotating sleeve 313 is rotatably connected to the push rod 311.

[0066] Example 2: Figures 1-2 and Figures 8-9 As shown, when cutting the blank, the blank is inserted into the cylinder 302. Then, the electric cylinder 312 can be activated to retract it, so that the rotating sleeve 313 and the push rod 311 can pull the two rotating rings 308 to rotate outside the cylinder 302. As the rotating rings 308 rotate, the movable frame 304 can be pushed to slide on the limit frame 303 through the cooperation of the movable groove 310 and the column rod 309, so that the two sets of rollers 306 can clamp and fix the blank together. The blank is fixed by the friction of the rollers 306. If the blank needs to be moved, the two rotating motors 307 below can be activated to rotate the two rollers 306 below, so that the blank can be moved, which facilitates continuous cutting of the blank, and also facilitates fixing and moving the blank to perform continuous cutting.

[0067] An external gear ring 314 is fixedly installed on one side of the electric cylinder 312 outside the cylinder 302, and a drive motor 315 is fixedly installed on the upper side of one side of the positioning frame 301. A rotating gear 316 is fixedly installed at the output end of the drive motor 315, and the rotating gear 316 meshes with the external gear ring 314.

[0068] Example 3: Figures 8-9As shown, when cutting the blank, the drive motor 315 can be started to drive the rotating gear 316 to rotate. After the rotating gear 316 rotates, it can drive the cylinder 302 to rotate clockwise through the external gear ring 314 on the outside of the cylinder 302, so that the blank can rotate. Thus, the blank can rotate during the cutting process, which can improve the cutting efficiency of the blank. When cooling the cutting position of the blank, the water spray pipe 207 will not rotate. After the blank rotates clockwise, some cooling water can be carried 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.

[0069] Working principle: When using the blank cutting device processed by this flange, firstly, according to Figures 1-9 As shown, when cutting the blank, the electric push rod 103 is activated to move the movable plate 105 downward. The cutting mechanism 107 drives the cutting blade to rotate via a motor. As the movable plate 105 moves downward, it can pull the pull rope 214. 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 connecting plate 213 can pull the two movable rods 201 to move, which stretches the telescopic spring 211, allowing 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, water is pumped from the water tank 110 through the water pump 209's water pipe 210. Then, the water flows into the water spray pipe 207 through the connecting hose 208. In step 7, water is sprayed through the water spray pipe 207 to cool the cutting area of ​​the blank. The cooling water can flow back into the water tank 110 through the channel 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 down, so that the cutting depth will continuously increase. The water spray pipe 207 can extend into the cutting depth, which can ensure that the blank can be fully cooled during the cutting process. The cross-section of the water spray pipe 207 is small and the water sprayed from the water spray pipe 207 has a high flow rate. After the water flow impacts the blank, it can drive the connecting frame 204 and the rotating shaft 202 to rotate through the reaction force, which can drive 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 the water spraying process to expand the water spraying range and fully cool the cutting area.

[0070] When cutting the blank, the blank is inserted into the cylinder 302. Then, the electric cylinder 312 can be activated to retract it, allowing the rotating sleeve 313 and push rod 311 to pull two rotating rings 308 to rotate outside the cylinder 302. As the rotating rings 308 rotate, the movable slot 310 and column rod 309 cooperate to push the movable frame 304 to slide on the limiting frame 303, allowing the two sets of rollers 306 to clamp and fix the blank together. The friction of the rollers 306 fixes the blank. If the blank needs to be moved, the two lower rotating motors 307 can be activated, causing the two lower rollers 306 to rotate, allowing the blank to move. This facilitates continuous cutting of the blank and, consequently, fixation. The design allows for stable and convenient movement of the blank, enabling continuous cutting. During cutting, the drive motor 315 can be activated to rotate the rotating gear 316. The rotating gear 316, in turn, engages with the external gear ring 314 on the outside of the cylinder 302, causing the cylinder 302 to rotate clockwise. This rotation of the blank during cutting improves cutting efficiency. Furthermore, when cooling the cutting area, the water spray pipe 207 remains stationary. The clockwise rotation of the blank carries some cooling water to the cutting blade, allowing the water to flow within the cutting kerf, thus enhancing cooling uniformity and extending the blade's lifespan.

A rotating gear (316) is fixedly installed at the output end of the drive motor (315), and the rotating gear (316) meshes with the external gear ring (314).

7. An operating method for a flange processing blank cutting device, comprising the flange processing blank cutting device as described in claim 6, characterized in that, The specific operating method is as follows: Step 1: When cutting the blank, the electric push rod (103) is activated to move the movable plate (105) downward. The cutting mechanism (107) drives the cutting blade to rotate via a motor. As the movable plate (105) moves downward, it pulls the pull rope (214) to move. After the pull rope (214) moves, it drives the first guide wheel (217) and the second guide wheel (219) to rotate, guiding the movement of the pull rope (214). Then, the connecting plate (213) pulls the two movable rods (201) to move, which stretches the telescopic spring (211) and drives the support frame. (206) moves with the water spray pipe (207). 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) cuts the blank. During the cutting process, water is pumped from the water tank (110) through the water pump (209) pump pipe (210). Then the water flows into the water spray pipe (207) through the connecting hose (208). Water is sprayed through the water spray pipe (207) to cool the cut part of the blank. The cooling water passes through the channel (108) and the filter screen (109) again. As the cutting process progresses, the electric push rod (103) gradually drives the cutting mechanism (107) to move downwards, increasing the cutting depth. The water spray pipe (207) extends further into the cutting depth to ensure sufficient cooling of the blank during the cutting process. The water spray pipe (207) has a small cross-section and a high water flow rate. After the water flow impacts the blank, the reaction force drives the connecting frame (204) and the rotating shaft (202) to rotate, causing the torsion spring (203) to deform. Then, under the action of the torsion spring (203), the connecting frame (204) is reset, and the water spray pipe (207) swings back and forth during the water spraying process to expand the water spraying range and fully cool the cutting area. The cooling component (2) ensures that the cutting area of ​​the blank is fully cooled when the blank is cut, and the position of the water spray pipe (207) moves with the change of cutting depth to ensure that the cutting end face of the blank is fully cooled, so as to avoid affecting the performance of the flange afterward, avoid the adhesion of debris, save water flow, and improve practicality. Step Two: When cutting the blank, the blank is inserted into the cylinder (302), and then the electric cylinder (312) is activated to retract, so that the two rotating rings (308) are pulled to rotate outside the cylinder (302) by the rotating sleeve (313) and the push rod (311). As the rotating rings (308) rotate, the movable frame (304) is pushed to slide on the limit frame (303) through the cooperation of the movable groove (310) and the column rod (309), so that the two sets of rollers (306) clamp and fix the blank together. The blank is fixed by the friction of the rollers (306). If the blank needs to be moved, the two rotating motors (307) below are activated, so that the two rollers (306) below rotate, so that the blank can be moved, which facilitates continuous cutting of the blank, and thus facilitates fixing of the blank and moving of the blank for continuous cutting. Step 3: When cutting the blank, the drive motor (315) is started to drive the rotating gear (316) to rotate. After the rotating gear (316) rotates, it drives the cylinder (302) to rotate clockwise through the external gear ring (314) on the outside of the meshing cylinder (302), which drives the blank to rotate. Thus, the blank rotates during the cutting process, which improves the cutting efficiency of the blank. When the blank is cooled at the cutting position, the water spray pipe (207) will not rotate. After the blank rotates clockwise, some cooling water is carried to the cutting blade. The cooling water flows in the cutting gap, which improves the uniformity of cooling and cools the cutting blade, thus improving the service life of the cutting blade.
