Description

Technical Field

[0001] This utility model belongs to the field of flange corner grinding technology, and specifically relates to a flange corner grinding device. Background Technology

[0002] Angle iron is bent using specialized equipment, ensuring that the angle steel retains its two sides at 90° angles after processing, without any folds or wrinkles. This processing method allows angle steel flanges to maintain their original structural strength while providing better connectivity and sealing, making them widely used in various structures requiring angle steel connections. During flange production, to avoid burrs, grinding equipment is used to improve the quality of the flanges.

[0003] Problems with existing technology:

[0004] Current grinding equipment has certain limitations. It cannot grind both sides of the flange corner simultaneously, which greatly limits the grinding efficiency. In addition, the equipment does not have the function of flexibly adjusting according to the flange corner thickness, making it difficult to adapt to the grinding needs of flange corners of different specifications in practical applications, thereby reducing the versatility and practicality of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a flange corner grinding device that can simultaneously grind both sides of the flange corner and has the ability to make precise adjustments according to the specific thickness of the flange corner, thus significantly improving the effectiveness of the equipment.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A flange angle grinding device includes a base plate. Two guide rods are fixed to one side of the top of the base plate. A movable plate is slidably installed between the outer walls of the two guide rods. A moving assembly for driving the movable plate is provided on the top of the base plate. Two arc-shaped grooves are symmetrically opened on one side of the movable plate. Arc-shaped blocks are slidably installed inside the two arc-shaped grooves. A limit block is fixed to one side of the arc-shaped blocks. A push plate is slidably installed on the outer wall of the movable plate between the two arc-shaped grooves. A limit groove is opened on the outer wall of the push plate and slidably connected to the limit block. A second hydraulic cylinder connected to the push plate is provided on the outer wall of the movable plate. A shaft is rotatably installed on the other side of the arc-shaped blocks. A first gear is fixed to the outer wall of each shaft. A motor is provided on one side of the movable plate. A second gear meshing with the two first gears is fixed to the output shaft of the motor. A detachable grinding roller is provided on the outer wall of the shaft and on the side of the first gear.

[0008] A baffle is fixed to the outer wall of the two shafts on one side of the first gear. A plurality of plug-in blocks are arranged on one side of the baffle along the circumferential direction. An installation tube fixed to the grinding roller is sleeved on the outer wall of the shaft. A limiting hole that cooperates with the plug-in block is opened on one side of the installation tube. A fixing disc is threaded to one end of the shaft on the side of the grinding roller.

[0009] The moving component includes a first hydraulic cylinder fixed to the top of the base plate.

[0010] A movable block is slidably mounted on the top of the base plate, and a third hydraulic cylinder is provided on the top of the base plate to drive the movable block to move. The movable block is provided with a clamping mechanism that can clamp the flange corner.

[0011] The clamping mechanism includes a fourth hydraulic cylinder on each of the top two sides of the moving block. The output shaft of the fourth hydraulic cylinder is fixed with a gripper, and one side of the gripper is bent at ninety degrees to form a limiting protrusion.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This invention utilizes a motor to drive a second gear, which in turn drives two first gears to rotate synchronously. This, in turn, drives the grinding wheels on the shafts to rotate synchronously, enabling simultaneous grinding of both sides of the flange angle. Simultaneously, a second hydraulic cylinder moves a limiting groove on a push plate, which, in conjunction with an upper limit block, pushes an arc-shaped block. The arc-shaped block drives two shafts to move synchronously, adjusting the distance between the grinding rollers on the two shafts to accommodate flange angles of varying thicknesses. This allows for simultaneous grinding of both sides of the flange angle and provides precise adjustment based on the specific thickness of the flange angle, significantly improving the equipment's performance. The grinding rollers, through the cooperation of the mounting tube, limiting holes, baffle, and fixing plate, facilitate easy installation, fixing, disassembly, and replacement, extending the equipment's service life.

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a flange angle grinding device includes a base plate 1. Two guide rods 2 are fixed to one side of the top of the base plate 1. A movable plate 3 is slidably installed between the outer walls of the two guide rods 2. A movable assembly for driving the movable plate 3 is provided on the top of the base plate 1. Two arc-shaped grooves 5 are symmetrically opened on one side of the movable plate 3. Arc-shaped blocks 6 are slidably installed inside the two arc-shaped grooves 5. A limit block 7 is fixed to one side of the arc-shaped blocks 6. A push plate 9 is slidably installed on the outer wall of the movable plate 3 between the two arc-shaped grooves 5. A limit groove 10 is opened on the outer wall of the push plate 9 and slidably connected to the limit block 7. A second hydraulic cylinder 8 connected to the push plate 9 is provided on the outer wall of the movable plate 3. The other arc-shaped block 6... A shaft 11 is rotatably mounted on one side, and a first gear 12 is fixed to the outer wall of the shaft 11. A motor 13 is provided on one side of the moving plate 3, and a second gear 14 that meshes with the two first gears 12 is fixed to the output shaft of the motor 13. A detachable grinding roller 15 is provided on the outer wall of the shaft 11 and on one side of the first gear 12. Two arc-shaped grooves 5 and the second gear 14 are set on the same concentric circle to facilitate the two first gears 12 to always mesh with the second gear 14 during the movement. The moving assembly includes a first hydraulic cylinder 4 fixed to the moving plate 3 on the top of the base plate 1. The moving assembly is not limited to a hydraulic cylinder, but can be a screw moving mechanism or a linear motor.

[0023] According to the above structure, during use, the second hydraulic cylinder 8 is activated based on the thickness of the flange angle. The second hydraulic cylinder 8 drives the push plate 9 to move. Through the cooperation of the limit block 7 and the limit groove 10, the arc block 6 is pushed to move along the arc groove 5. The arc block 6 drives the shaft 11 to move. The shaft 11 drives the grinding roller 15 to move. The distance between the two grinding rollers 15 is adjusted according to the thickness of the flange angle. During the movement, the first gear 12 and the second gear 14 are always meshed. Then the motor 13 is activated. The motor 13 drives the second gear 14. The second gear 14 meshes with the first gear 12, causing the grinding roller 15 on the shaft 11 to rotate and grind the flange angle.

[0024] like Figures 3-4 As shown, a baffle 18 is fixed on the outer wall of the two shafts 11 and on one side of the first gear 12. A plurality of plug-in blocks are arranged on one side of the baffle 18 along the circumferential direction. An installation tube 16 fixed to the grinding roller 15 is sleeved on the outer wall of the shaft 11. A limiting hole 17 that cooperates with the plug-in block is opened on one side of the installation tube 16. A fixing plate 19 is threadedly connected to one end of the shaft 11 and on the side of the grinding roller 15.

[0025] According to the above structure, by unscrewing the fixing plate 19, removing the damaged grinding roller 15, replacing it with a new grinding roller 15 and fitting it onto the shaft 11, inserting the plug into the limiting hole 17, and finally screwing the fixing plate 19 back on, the grinding roller 15 is fixed. The structure is simple, making it convenient to replace the grinding roller 15 and improving the service life of the equipment.

[0026] like Figure 1-Figure 2 As shown, a movable block 20 is slidably mounted on the top of the base plate 1. A third hydraulic cylinder 21 is provided on the top of the base plate 1 to drive the movable block 20 to move. The movable block 20 is provided with a clamping mechanism that can clamp the flange corner, which can drive the flange corner on the movable block 20 to move, so as to push the flange corner between the two grinding rollers 15. The clamping mechanism includes a fourth hydraulic cylinder on both sides of the top of the movable block 20. The output shaft of the fourth hydraulic cylinder is fixed with a gripper 22. One side of the gripper 22 is bent at ninety degrees to form a limiting protrusion, which improves the stability of clamping the flange corner.

[0027] The working principle of this utility model is as follows: During use, according to the thickness of the flange angle, the second hydraulic cylinder 8 is activated, which drives the push plate 9 to move. Through the cooperation of the limiting block 7 and the limiting groove 10, the arc block 6 is pushed to move along the arc groove 5. The arc block 6 drives the shaft 11 to move, and the shaft 11 drives the grinding roller 15 to move. According to the thickness of the flange angle, the distance between the two grinding rollers 15 is adjusted. During the movement, the first gear 12 and the second gear 14 are always meshed. The fourth hydraulic cylinder is activated, which drives the gripper 22 to clamp the flange angle. Then, the third hydraulic cylinder 21 pushes the moving block 20 to move, and moves the flange angle between the two grinding rollers 15. Then, the motor 13 is activated, which drives the second gear 14. The second gear 14 meshes with the first gear 12 to rotate the grinding roller 15 on the shaft 11 and grind the flange angle.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
