Technical Field

[0001] This utility model relates to the field of flange manufacturing, and in particular to a grinding device for a high-temperature resistant flat welding flange. Background Technology

[0002] In industrial production, high-temperature resistant slip-on flanges are widely used in pipeline connection systems under various high-temperature environments. With the continuous development of industrial technology, the quality requirements for high-temperature resistant slip-on flanges are becoming increasingly stringent. During the flange production process, grinding is a crucial step in ensuring its surface quality and dimensional accuracy.

[0003] In the production of high-temperature resistant slip-on flanges, grinding is a crucial step. Traditional slip-on flange grinding equipment often presents several problems. Firstly, when the flange needs to be flipped, manual adjustment is usually required, which is not only cumbersome and labor-intensive but also inefficient and poses safety hazards to workers. Secondly, manual flipping makes it difficult to guarantee accuracy and stability, potentially leading to uneven grinding and affecting the flange's quality.

[0004] Therefore, it is necessary to provide a new grinding device for high-temperature resistant flat-face welding flanges to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a grinding device for a high-temperature resistant flat welding flange.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 4 A grinding device for a high-temperature resistant flat-welded flange includes: a base 1, a back plate 11 fixedly connected to the base 1, protruding plates 12 at both ends of the base 1, a fixed rod 2 fixedly connected between the two protruding plates 12, a movable seat 3 slidably connected to the fixed rod 2, a placement groove on the movable seat 3, a drive rotating assembly 31 in the placement groove, a rotating shaft 32 rotatably connected between the two protruding plates 12, a motor 33 mounted on one end of the protruding plate 12, the output end of the motor 33 fixedly connected to the rotating shaft 32, the rotating shaft 32 being a threaded rod, the movable seat 3 being threadedly connected to the rotating shaft 32, and a grinding roller 4 mounted on the back plate 11; a built-in flipping mechanism, including a built-in ring 5, the built-in ring 5 being disposed in the placement groove on the movable seat 3, side support columns 51 at both ends of the built-in ring 5, short shafts 52 fixedly connected to one end of each side support column 51, a mating frame 53 below the movable seat 3, the two short shafts 52 being rotatably connected to both ends of the mating frame 53 respectively, and a control component at one end of the mating frame 53.

[0022] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the control assembly includes an extension shaft 6, which is fixedly connected to a short shaft 52 at one end. A small electric cylinder 61 is installed and connected to one end of the mounting bracket 53. A rack 62 is fixedly connected to the output end of the small electric cylinder 61. A gear 63 is installed and connected on the extension shaft 6, and the rack 62 and the gear 63 mesh with each other.

[0023] It should be noted that: the extension end of the small electric cylinder 61 drives the rack 62 to move, which in turn drives the gear 63 that meshes with it to rotate the extension shaft 6. The extension shaft 6 drives the inner ring 5 between the two short shafts 52 to rotate and reverse, so that the flange can be automatically flipped over for further grinding.

[0024] refer to Figure 1 and Figure 3 As shown, both ends of the placement groove are provided with limiting grooves, and the two side support columns 51 are respectively located in the two limiting grooves.

[0025] It should be noted that the two limiting slots are designed to accommodate the two side support pillars 51, allowing the inner ring 5 to be reset and placed into the slot in the movable seat 3.

[0026] refer to Figure 1 and Figure 2 As shown, a bracket plate 7 is fixedly connected to the movable seat 3, and a main electric cylinder 71 is installed on the bracket plate 7. The telescopic end of the main electric cylinder 71 is fixedly connected to the middle position of the cooperating frame 53.

[0027] It should be noted that the main electric cylinder 71 causes its telescopic end to move the mating frame 53 upward, so that the mating frame 53 can simultaneously drive the inner ring 5 upward, thereby moving the flange upward to leave the placement slot, which facilitates further flipping later.

[0028] refer to Figure 1 and Figure 3 As shown, the inner ring 5 has an inner groove on both sides of its inner wall, and a fitting piece 8 is provided at each of the two inner grooves.

[0029] It should be noted that the two mating pieces 8 move relative to each other and press against the flange in the placement groove, so as to facilitate the subsequent flipping of the flange.

[0030] refer to Figure 3 and Figure 4 As shown, an internal tube 81 is fixedly connected to one end of each of the two embedded slots. A slide rod 82 is slidably connected to one end of each of the two internal tubes 81. One end of each slide rod 82 is fixedly connected to one of the two fitting pieces 8. A magnetic block 83 is fixedly connected to the other end of each of the two slide rods 82. A spring 84 is sleeved on each of the two slide rods 82. An electromagnet 85 is fixedly connected to the inner wall of one end of each of the two internal tubes 81. The magnetic poles of the two electromagnets 85 are the same as those of the two magnetic blocks 83.

[0031] It should be noted that: controlling the energization of the two electromagnets 85 to generate magnetism, driving the two magnetic blocks 83 to move the two slide rods 82, which are equivalent to the sliding of the walls of the two built-in tubes 81. One end of the two slide rods 82 drives the two fitting pieces 8 to move relative to each other and press against the flange in the placement groove, thereby fastening the flange.

[0032] The working principle of the grinding device for a high-temperature resistant flat welding flange provided by this utility model is as follows: When it is necessary to flip the flange, the two electromagnets 85 are energized to generate magnetism, which drives the two magnetic blocks 83 to move the two sliding rods 82, which are equivalent to the pipe walls of the two built-in tubes 81. One end of the two sliding rods 82 drives the two fitting pieces 8 to move relative to each other and press against the flange in the placement groove, so as to facilitate the subsequent flipping of the flange.

[0033] The main electric cylinder 71 is activated so that its telescopic end moves the mating frame 53 upward, which in turn drives the inner ring 5 upward, moving the flange upward until it leaves the placement slot. Then, the small electric cylinder 61 is activated so that its telescopic end moves the rack 62, which in turn drives the gear 63 that meshes with it to rotate. The gear 63 drives the extension shaft 6 to rotate, and the extension shaft 6 drives the inner ring 5 between the two short shafts 52 to rotate in reverse. Then, the telescopic end of the main electric cylinder 71 retracts and resets, so that the flange can be automatically flipped for further grinding without manual adjustment, which is very convenient and quick.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
