Description

Technical Field

[0001] This invention relates to the field of flange processing technology, and more specifically to a flange cutting device with burr removal function. Background Technology

[0002] A flange, also called a flange disc or flange, is a part used to connect shafts, for connecting pipe ends, and also for connecting two pieces of equipment at their inlets and outlets. Before processing, the flange blank is a long cylindrical blank, which needs to be cut on a saw. Because the blank is long and large, the cutting process is inconvenient and prone to warping, which seriously affects the cutting accuracy of the saw. Moreover, the cut surface is prone to burrs, which need to be ground in the later processing, reducing the efficiency of flange processing. Therefore, this invention proposes a flange cutting device with burr removal function.

[0003] In the prior art, a Chinese patent document with publication number CN116079148A and publication date of May 9, 2023 was proposed to solve the above-mentioned technical problem. The technical solution disclosed in the patent document is as follows: A blank cutting device for flange processing, relating to the field of blank cutting technology, includes a frame, a blank collection box fixedly installed on one end of the bottom plate of the frame, and a lower support mechanism, which is fixedly installed on the top plate of the frame for supporting and conveying long flange blanks. The lower support mechanism includes a fixed-length moving part, which is installed on the lower support frame. A clamping and rotating mechanism is fixedly installed on the top plate of the frame and located in front of the lower support mechanism. The clamping and rotating mechanism includes a clamping and rotating part and a clamping and fixing part for clamping and fixing the long flange blank and making the long flange blank rotate stably.

[0004] To address the problem of long and large blanks making the cutting process inconvenient, prone to warping, and severely affecting the cutting accuracy of the saw, existing technology employs a lower and upper support mechanism. A screw drive is used to change the positions of the conveyor rollers and support rollers, supporting the long flange blank in both upper and lower positions.

[0005] While the material can be processed in a way that ensures the horizontal stability of the flange blank, there is still a situation where burrs after cutting cannot be removed, which leads to inconvenience in the subsequent flange processing. Summary of the Invention

[0006] The present invention provides a flange cutting device with burr removal function to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] A flange cutting device with burr removal function includes a flange cutting device body, a processing base at the bottom of the flange cutting device body, a flange blank conveying and clamping mechanism above the processing base, and a cutting and grinding assembly mechanism at the front end of the flange blank conveying and clamping mechanism. The flange blank conveying and clamping mechanism includes a flange blank conveying unit and a cutting support unit. The flange blank conveying unit is located at the rear end of the processing base, and the cutting support unit is located at the front end of the processing base. The cutting and grinding assembly mechanism includes a movable gantry unit and a cutting and grinding unit. The movable gantry unit is located on both sides of the cutting support unit, and the cutting and grinding unit is located above the movable gantry unit.

[0018] Using the above technical solution, the V-shaped bearing long support and the V-shaped bearing short support have the same basic structure to support the flange blank. The flange blank stabilizing baffle has a continuous pressing force on the extrusion gasket, so that the compression ring tightens the flange blank.

[0019] A further improvement of the technical solution of the present invention is that: the movable gantry unit includes a gantry that is slidably installed on the upper surface of the front end of the processing base, and a rack is provided below the gantry, the lower surface of the rack being fixedly connected to the upper surface of the front end of the processing base.

[0021] A further improvement of the technical solution of the present invention is that: a driving gear and a driven gear are rotatably mounted on the bottom outer surface of the gantry frame, the driven gear meshes with the driving gear, and the lower surface of the driven gear meshes with the upper surface of the rack.

[0022] Using the above technical solution, the driving gear is driven by a motor installed on the side wall of the gantry, and the rotation of the driving gear drives the driven gear to rotate.

[0023] A further improvement of the technical solution of the present invention is that: the cutting and grinding unit includes a threaded rod II fixedly installed between the inner side walls above the gantry frame, and a movable slide rail is provided in the middle of the threaded rod II, and the two ends of the movable slide rail are respectively rotatably connected to the side walls of the gantry frame.

[0025] A further improvement of the technical solution of the present invention is that: the cutting and grinding unit further includes a movable platform slidably installed between the two threaded rods, the inner wall of the movable platform is threadedly connected to the outer surface of the movable slide rail, a high-pressure water jet cutting equipment assembly is fixedly installed on the front surface of the movable platform, a grinding equipment mounting bracket is fixedly installed on the rear surface of the movable platform, a telescopic rod is fixedly installed above the grinding equipment mounting bracket, and a grinding equipment assembly is fixedly installed at the output end of the telescopic rod.

[0026] Using the above technical solution, the upper and lower ends of the mobile platform are respectively equipped with rollers that are compatible with the threaded rod. The grinding equipment components include a mounting frame, a drive motor, a rotating shaft, grinding rollers and other accessories.

[0027] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0028] 1. This invention provides a flange cutting device with burr removal function. A threaded rod is driven to rotate by a motor installed on the side of the processing base. A limiting rod limits the movement of the fixed block at the tail of the flange blank. The tail end of the flange blank passes through the center clamping triangle between the fixed block at the tail of the flange blank. Under the elastic action of the limiting spring, the clamping triangle is pressed against the surface of the flange blank. The clamping triangle is a triangular block, which minimizes the contact area and increases the pressure between the clamping triangle and the flange blank to fix the flange blank. The rotation of the threaded rod causes the connecting rod to move the fixed block at the tail of the flange blank, clamping the flange blank, under the limiting action of the limiting rod, so as to realize automatic cutting and feeding.

[0029] 2. This invention provides a flange cutting device with burr removal function. A water tank is provided on the upper surface of the cutting water tank. The V-shaped long support and the V-shaped short support serve to support the flange blank at the cutting point. The gap between the V-shaped long support and the V-shaped short support is the cutting groove. The flange blank stabilizing baffle has a continuous pressing force on the extrusion folding pad, so that the compression ring tightens the flange blank and avoids shaking during cutting. At the same time, it fixes the cut flange blank, which is convenient for burr grinding on the cut surface.

[0030] 3. The present invention provides a flange cutting device with burr removal function. The driving gear is driven to rotate by a motor installed on the side wall of the gantry, and meshes with the driven gear to drive the driven gear to rotate. The driven gear, in cooperation with the rack, causes the gantry to move back and forth, switching between cutting and grinding processes, thereby improving the practicality of the device.

[0031] 4. This invention provides a flange cutting device with burr removal function. The moving slide rail is driven by a motor installed above the side wall of the gantry frame. The moving platform moves left and right under the limiting cooperation of the threaded rod two to meet the processing requirements of cutting and grinding. The pulleys set at the upper and lower ends of the moving platform reduce the sliding friction with the threaded rod two. The high-pressure water jet cutting equipment assembly installed on the front side of the moving platform uses high-pressure water jet to cut the flange blank. The telescopic rod on the grinding equipment mounting frame installed on the rear side of the moving platform descends to allow the motor and grinding roller installed on the grinding equipment assembly to grind the burrs on the cut section, thereby improving the efficiency of flange processing.

A limiting rod 211 is provided on one side of the threaded rod 21. The two ends of the limiting rod 211 are fixedly connected to the other side of the processing base 11. The threaded rod 21 is driven to rotate by a motor installed on the side of the processing base 11. The limiting rod 211 has the function of limiting the movement of the flange blank tail fixing block 22. The flange blank conveying unit also includes a flange blank tail fixing block 22. Connecting rods 223 are fixedly installed on both sides of the flange blank tail fixing block 22. The inner wall of one side of the connecting rod 223 is threadedly connected to the outer surface of the threaded rod 21. The inner wall of the other side of the connecting rod 223 is slidably connected to the outer surface of the limiting rod 211. The tail end of the flange blank is passed through the central clamping triangle 221 of the flange blank tail fixing block 22. The clamping triangle 221 is pressed against the surface of the flange blank under the elastic action of the limiting spring 222.

[0043] Furthermore, the clamping tripod 221 is a triangular block, which minimizes the contact area and increases the pressure between the clamping tripod 221 and the flange blank, thus fixing the flange blank. The rotation of the threaded rod 21 causes the connecting rod 223 to move while the flange blank is clamped by the fixed block 22 at the tail of the flange blank under the limiting cooperation of the limiting rod 211. Example

[0044] like Figure 1-8As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a clamping tripod 221 is symmetrically slidably installed on the inner side wall of the flange blank tail fixing block 22.

A flange blank stabilizing baffle 26 is fixedly installed on the upper surface of both the V-shaped bearing long support 24 and the V-shaped bearing short support 25. A pressure ring 262 is hinged to the inner wall of the flange blank stabilizing baffle 26. A compression folding pad 261 is fixedly installed between the outer surface of the compression ring 262 and the inner surface of the flange blank stabilizing baffle 26. The gap between the V-shaped bearing long support 24 and the V-shaped bearing short support 25 is the cutting groove. The flange blank stabilizing baffle 26 exerts a continuous pressing force on the compression folding pad 261, so that the pressure ring 262 tightens the flange blank, preventing shaking during cutting. At the same time, it fixes the cut flange blank, which is convenient for grinding the burrs on the cut surface. Example

[0045] like Figure 1-8 As shown, based on embodiments 1-2, the present invention provides a technical solution: Preferably, the movable gantry unit includes a gantry 31 slidably mounted on the upper front surface of the processing base 11. A rack 32 is provided below the gantry 31, and the lower surface of the rack 32 is fixedly connected to the upper front surface of the processing base 11. The drive gear 33 is driven to rotate by a motor mounted on the side wall of the gantry 31. The drive gear 33 and the driven gear 331 are rotatably mounted on the outer bottom surface of the gantry 31, respectively. The driven gear 331 meshes with the drive gear 33, and the lower surface of the driven gear 331 meshes with the upper surface of the rack 32. The meshing of the drive gear 33 and the driven gear 331 drives the driven gear 331 to rotate. With the cooperation of the rack 32, the driven gear 331 causes the gantry 31 to move back and forth, switching between cutting and grinding processing programs, thus improving the practicality of the device. Example

[0046] like Figure 1-8As shown, based on embodiments 1-3, the present invention provides a technical solution: Preferably, the cutting and grinding unit includes a threaded rod 34 fixedly installed between the inner sidewalls above the gantry frame 31. A movable slide rail 35 is provided in the middle of the threaded rod 34. The two ends of the movable slide rail 35 are respectively rotatably connected to the sidewalls of the gantry frame 31. The movable slide rail 35 is driven by a motor installed above the sidewalls of the gantry frame 31. The moving platform 36 moves left and right under the limiting cooperation of the threaded rod 34 to meet the processing requirements of cutting and grinding. The cutting and grinding unit also includes a moving platform 36 slidably installed between the threaded rods 34. The inner wall of the moving platform 36 is threadedly connected to the outer surface of the moving slide rail 35. A high-pressure water jet cutting equipment assembly 37 is fixedly installed on the front surface of the moving platform 36, and a grinding equipment mounting bracket 38 is fixedly installed on the rear surface of the moving platform 36. A telescopic rod 39 is fixedly installed above the grinding equipment mounting bracket 38, and a grinding equipment assembly 391 is fixedly installed at the output end of the telescopic rod 39. The pulleys set at the upper and lower ends of the moving platform 36 reduce the sliding friction with the threaded rod 34. The high-pressure water jet cutting equipment assembly 37 installed on the front of the moving platform 36 uses high-pressure water jet to cut the flange blank. The telescopic rod 39 on the grinding equipment mounting bracket 38 installed on the rear of the moving platform 36 descends so that the motor and grinding roller installed on the grinding equipment assembly 391 can deburr the cut section.

[0047] The working principle of this flange cutting device with burr removal function will be explained in detail below.

[0048] like Figure 1-8 As shown, firstly, the tail end of the flange blank is passed through the central clamping triangle 221 between the flange blank tail fixing block 22. Under the elastic action of the limiting spring 222, the clamping triangle 221 presses against the surface of the flange blank, fixing the flange blank. The motor drives the threaded rod 21 to rotate, causing the connecting rod 223 to move and cut the flange blank with the flange blank clamped by the flange blank tail fixing block 22 under the limiting cooperation of the limiting rod 211. Then, the V-shaped bearing long support 24 and V-shaped bearing short support 25 support the flange blank at the cutting point. The flange blank stabilizing baffle 26 exerts a continuous pressing force on the compression folding pad 261, causing the compression ring 262 to be aligned with the flange blank. The flange blank is tightened, and the motor drives the drive gear 33 to rotate, causing the driven gear 331 to rotate. With the cooperation of the rack 32, the gantry 31 moves forward, and the high-pressure water jet cutting equipment assembly 37 moves to the cutting groove between the V-shaped long support 24 and the V-shaped short support 25. The flange blank is cut using a high-pressure water jet. Finally, the motor drives the drive gear 33 to rotate in the opposite direction, causing the driven gear 331 to rotate. With the cooperation of the rack 32, the gantry 31 moves backward, and the telescopic rod 39 moves to the cutting groove between the V-shaped long support 24 and the V-shaped short support 25. The telescopic rod 39 descends, and the motor and grinding roller installed on the grinding equipment assembly 391 deburr the cut section.

[0049] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
