Description

Technical Field

[0001] This utility model belongs to the technical field of flange processing equipment, and in particular, it is a flange scrap cutting device. Background Technology

[0002] During the flange production process, welded flanges often have excess material that needs to be cut. From a product quality perspective, flange scrap removal can remove excess material after welding, ensuring that the flange dimensions accurately meet standards and improving overall quality and performance. Traditional flange scrap cutting devices can meet basic usage requirements, but their rotational capacity is insufficient. The cutting device may jam or become unstable during rotation, which limits the increase in cutting speed and results in uneven cuts.

[0003] A search revealed a Chinese patent document (authorization announcement number CN212169356U), which discloses a flange cutting device, comprising a supporting base plate. Roller bearings are fixedly installed at the four corners of the upper surface of the supporting base plate. Connecting columns are snapped onto the upper ends of the roller bearings. A rotating handle is welded to one side of each connecting column. A threaded column is welded to the upper surface of each connecting column. A movable column is sleeved on the outer side of each threaded column. A threaded groove is provided on the inner side of each movable column. An operating platform is fixedly installed on the upper surface of the four movable columns. A slide rail is fixedly installed on one side of the upper surface of the operating platform. A drive box is slidably connected to the outer side of the slide rail. An electric push rod is fixedly installed on one side of the drive box. A laser is fixedly installed at one end of the electric push rod. This utility model has a simple structure, is easy to operate and use, and is convenient for fixing the workpiece to be cut, thus improving the cutting accuracy. At the same time, the height of the device can be adjusted as needed. The device can meet basic usage requirements, but its rotational capacity is insufficient. The cutting device may jam or become unstable when rotating, which limits the increase in cutting speed and results in uneven cuts. Utility Model Content

[0004] The purpose of this invention is to provide a flange scrap cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flange scrap cutting device, comprising a support platform for supporting flange scrap cutting, wherein a first motor for providing rotational power is provided on the top of the support platform, and the output shaft of the first motor is connected to a rotating disk via a coupling;

[0006] The rotating disk has a guide groove inside for guiding, and a threaded rod is rotatably installed inside the guide groove. A knob for rotation is installed at one end of the threaded rod, and a moving block is connected to the outer periphery of the threaded rod. A limiting plate for support is welded to the bottom of the moving block.

[0007] Preferably, a hollow block is welded to the end of the limiting plate away from the moving block, a spring is connected inside the hollow block, and one end of the spring is connected to the moving plate.

[0008] Preferably, a second motor is installed on the top of the movable plate, and the output shaft of the second motor is connected to a rotating column via a coupling. A grinding and cutting disc for cutting flange scrap is installed at the end of the rotating column.

[0009] Preferably, the hollow block has a guide groove on its side and U-shaped grooves on both sides, and the rotating column is slidably disposed inside the U-shaped grooves.

[0010] Preferably, a first lead screw mechanism is installed inside the support platform, and a movable cutting table for fixing flange components is installed on the moving part of the first lead screw mechanism.

[0011] Preferably, a fixed frame for support is welded to the side of the support platform, and a second lead screw mechanism is installed inside the fixed frame, with a first movable frame installed on the moving part of the second lead screw mechanism.

[0012] Preferably, a third lead screw mechanism is mounted on the side of the first movable frame, a second movable frame is mounted on the moving part of the third lead screw mechanism, and the first motor is mounted on the side of the second movable frame.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This flange scrap cutting device benefits from the structure of the rotating disk. The first motor drives the rotating disk to rotate, and the rotating disk drives the limiting plate and the grinding and cutting disk to rotate around the center of the rotating disk. Turning the knob drives the threaded rod to rotate, and the threaded rod drives the moving block to move. The moving block drives the limiting plate to move. Compared with the insufficient rotation capacity of traditional flange scrap cutting devices, this structure can improve the rotation capacity of the scrap cutting device, prevent the cutting device from jamming or becoming unstable during rotation, increase the cutting speed, and make the cut smoother.

[0015] This flange scrap cutting device, thanks to the structure of the hollow block and the moving plate, allows the flange components to compress the spring by driving the grinding and cutting disc and the moving plate when the grinding and cutting disc comes into contact with the flange components. This adapts to the contact pressure between the grinding and cutting disc and the flange components. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5The flange scrap cutting device shown includes a support platform 1 for supporting the cutting of flange scrap. A first motor 107 for providing rotational power is provided on the top of the support platform 1. The output shaft of the first motor 107 is connected to a rotating disk 108 through a coupling. When the first motor 107 is turned on, the first motor 107 drives the rotating disk 108 to rotate. The rotating disk 108 drives the limiting plate 3 and the grinding and cutting disk 308 to rotate around the center of the rotating disk 108.

[0027] The rotating disk 108 has a guide groove 2 for guiding. A threaded rod 201 is rotatably mounted inside the guide groove 2. A knob 202 for rotation is installed at one end of the threaded rod 201. A moving block 203 is connected to the outer periphery of the threaded rod 201. A limiting plate 3 for support is welded to the bottom of the moving block 203. If it is necessary to adjust the contact pressure between the grinding and cutting disk 308 and the flange components, the knob 202 is rotated. The knob 202 drives the threaded rod 201 to rotate, the threaded rod 201 drives the moving block 203 to move, and the moving block 203 drives the limiting plate 3 to move.

[0028] A hollow block 301 is welded to the end of the limiting plate 3 away from the moving block 203. A spring 302 is connected inside the hollow block 301, and damping is provided between the spring 302 and the hollow block 301. One end of the spring 302 is connected to the moving plate 303, and a second motor 304 is installed on the top of the moving plate 303. The output shaft of the second motor 304 is connected to a rotating column 307 through a coupling. A grinding and cutting disc 308 for cutting flange scrap is installed at the end of the rotating column 307. The grinding and cutting formed by the grinding and cutting disc 308 can usually achieve a relatively fine cut and can better control the size and shape of the cut. For some flange scraps requiring high precision, grinding and cutting can meet the requirements and reduce subsequent processing steps. The second motor 304 is turned on, which drives the rotating column 307 and the grinding and cutting disc 308 to rotate. The grinding and cutting disc 308 grinds and cuts the flange scraps. If it is necessary to adjust the contact pressure between the grinding and cutting disc 308 and the flange components, when the grinding and cutting disc 308 contacts the flange components, the flange components drive the grinding and cutting disc 308 and the moving plate 303 to squeeze the spring 302, which can adapt to the contact pressure between the grinding and cutting disc 308 and the flange components.

[0029] The hollow block 301 has a guide groove 306 on its side and U-shaped grooves 305 on both sides. The rotating column 307 is slidably disposed inside the U-shaped groove 305. The groove 306 and the U-shaped groove 305 can limit the movement of the second motor 304.

[0030] The support platform 1 is equipped with a first lead screw mechanism 102. The moving part of the first lead screw mechanism 102 is equipped with a movable cutting table 109 for fixing flange components. A fixing frame 101 for support is welded to the side of the support platform 1. The fixing frame 101 is equipped with a second lead screw mechanism 103. The moving part of the second lead screw mechanism 103 is equipped with a first moving frame 104. The side of the first moving frame 104 is equipped with a third lead screw mechanism 105. The moving part of the third lead screw mechanism 105 is equipped with a second moving frame 106. A first motor 107 is installed on the side of the second moving frame 106. The flange that needs to be cut is fixed on the movable cutting table 109. By adjusting the first lead screw mechanism 102, the flange on the movable cutting table 109 is moved to below the grinding and cutting disc 308. By adjusting the second lead screw mechanism 103 and the third lead screw mechanism 105, the edge of the grinding and cutting disc 308 is made to contact the edge of the flange component.

[0031] Working principle

[0032] In use, the flange scrap cutting device first fixes the flange to be cut onto the movable cutting table 109. By adjusting the first lead screw mechanism 102, the flange on the movable cutting table 109 is moved to below the grinding and cutting disc 308. By adjusting the second lead screw mechanism 103 and the third lead screw mechanism 105, the edge of the grinding and cutting disc 308 contacts the edge of the flange component. The first motor 107 is then turned on, driving the rotating disc 108 to rotate. The rotating disc 108 causes the limiting plate 3 and the grinding and cutting disc 308 to rotate around the center of the rotating disc 108. The second motor 304 is then turned on... The second motor 304 drives the rotating column 307 and the grinding and cutting disc 308 to rotate. The grinding and cutting disc 308 grinds and cuts the flange scrap. If it is necessary to adjust the contact pressure between the grinding and cutting disc 308 and the flange components, turn the knob 202. The knob 202 drives the threaded rod 201 to rotate. The threaded rod 201 drives the moving block 203 to move. The moving block 203 drives the limiting plate 3 to move. When the grinding and cutting disc 308 contacts the flange components, the flange components drive the grinding and cutting disc 308 and the moving plate 303 to squeeze the spring 302, which can adapt to the contact pressure between the grinding and cutting disc 308 and the flange components.
