Description

Technical Field

[0001] This utility model relates to the field of forging processing technology, specifically to a forging surface polishing device. Background Technology

[0002] Forgings are workpieces or blanks obtained by forging and deforming metal billets. The forging process applies pressure to induce plastic deformation in metal, thereby improving its mechanical properties and eliminating porosity and voids within the metal. Surface polishing is one of the key steps in the forging process, aiming to remove burrs, scratches, and other defects from the surface, improving the surface quality and gloss of the forging.

[0003] When polishing cylindrical or square forgings, existing polishing methods are divided into manual polishing and simple mechanical polishing. Manual polishing is inefficient and it is difficult to guarantee consistent quality. Although mechanical polishing can improve polishing efficiency to a certain extent, it still requires manual operation of the polishing machine and cannot achieve comprehensive and uniform polishing, making it difficult to meet the growing production demands for high precision and high efficiency. Summary of the Invention

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 2 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a forging surface polishing device, including a base 1, a rotating table 3, a driving mechanism 4, a positioning fixture 5, a polishing mechanism 8, a lifting mechanism 7, and a moving mechanism 6;

[0030] A rotating platform 3 is disposed above the base 1. The rotating platform 3 is connected to the base 1 via a rotating shaft 2. One end of the rotating shaft 2 is fixedly connected to the rotating platform 3, and the other end of the rotating shaft 2 is rotatably connected to the base 1 via a bearing.

[0031] The drive mechanism 4 includes a drive motor 41, a drive pulley 43, a driven pulley, and a transmission belt 42. The drive motor 41 is fixed on the base 1. The output shaft of the drive motor 41 is connected to the drive pulley 43. The driven pulley is fixed on the outer side of the rotating shaft 2. The transmission belt 42 is sleeved between the drive pulley 43 and the driven pulley. The rotation of the rotary table 3 is controlled by the belt drive, so that the polishing wheel 82 polishes the surface of the forging around one revolution.

[0032] The positioning fixture 5 includes a fixed platform 51, a positioning groove 52, and a forging fixing mechanism 53. The fixed platform 51 is detachably fixed to the rotary table 3 by bolts. The positioning groove 52 is located in the middle of the upper surface of the fixed platform 51. The positioning groove 52 is adapted to the bottom shape of the forging to be polished. The fixed platform 51 can be replaced according to the shape of the forging to be polished. The positioning groove 52 can be a circular groove or a square groove.

[0033] To prevent the forging from shifting during polishing, forging fixing mechanisms 53 are evenly distributed around the circumference of the fixed table 51. The forging fixing mechanism 53 includes a fixing frame 531, a hydraulic cylinder 532, and a pressure block 533. The fixing frame 531 is fixed on the rotary table 3, and the hydraulic cylinder 532 is fixed on one side of the fixing frame 531. The telescopic end of the hydraulic cylinder 532 is connected to the pressure block 533. The pressure block 533 faces the forging to be polished. The hydraulic cylinder 532 drives the pressure block 533 to press and fix the surface of the forging.

[0034] Furthermore, in order to improve the stability of fixing the forging, there are four forging fixing mechanisms 53, which are evenly distributed along the central axis of the rotary table.

[0035] Polishing mechanism 8 includes polishing motor 81 and polishing wheel 82. Polishing wheel 82 is connected to the output shaft of polishing motor 81. Polishing wheel 82 is rotated by polishing motor 81 to polish the surface of forging.

[0036] The lifting mechanism 7 includes a frame 71, a screw 72, a lifting motor 73, and a lifting block 74. The frame 71 is fixed to the upper end of the linear motor 62. One side of the frame 71 has an opening facing the rotary table 3. The screw 72 is installed inside the frame 71, and its upper end is connected to the output end of the lifting motor 73. The lifting block 74 is threaded to the outer side of the screw 72. A mounting plate 75 is provided on one side of the lifting block 74. The polishing motor 81 is fixed to the lower end of the mounting plate 75. The screw 72 is rotated by the lifting motor 73, which in turn controls the lifting block 74 to move up and down. This controls the polishing wheel 82 to move up and down, polishing along the height direction of the forging to ensure the uniformity and consistency of the polishing on the surface of the forging.

[0037] Furthermore, it also includes a moving mechanism 6, which includes a linear slide rail 61 and a linear motor 62. The linear slide rail 61 is fixed on the upper surface of the base 1, and the linear motor 62 is mounted on the linear slide rail 61 and moves back and forth along the linear slide rail 61. The polishing wheel 82 is controlled to fit against the forging for polishing according to the size of the forging, thereby improving the versatility of the device.

[0038] In use: According to the shape of the forging to be polished, replace the fixed platform 51 with one that matches the bottom shape of the forging. Then place the lower end of the forging in the positioning groove 52. At this time, start the hydraulic cylinder 532 and fix the forging by the pressure block 533. Start the linear motor 62 to move it horizontally until the polishing wheel 82 contacts the surface of the forging. Then start the drive motor 41 and control the rotary table 3 to rotate under the action of the transmission belt 42 to polish the forging one revolution. By starting the lifting motor 73, control the screw 72 to rotate, and then control the polishing wheel 82 to move up and down to polish along the height direction of the forging.

[0039] To avoid polishing blind spots, after polishing is completed, the fixed end of the forging is rotated to perform full polishing.

[0040] This invention can polish cylindrical and square forgings of different sizes, improving the uniformity and consistency of polishing while ensuring polishing efficiency, meeting existing production cycles, and improving polishing quality.
