Description

Technical Field

[0001] This invention relates to the field of metal forging and polishing technology, specifically to a forging device for metal processing and manufacturing that improves the contact fatigue strength of tooth surfaces. Background Technology

[0002] Fluid polishing technology is a processing method used for surface treatment and surface finish improvement. It uses a mixture of abrasive particles and liquid to remove defects on the workpiece surface, improve surface quality, and increase gloss. It is commonly used in manufacturing, especially in the processing of materials such as metals, plastics, and ceramics. Polishing fluids are important materials for surface polishing and surface finish improvement. Depending on different application requirements and workpiece materials, there are various types of polishing fluids to choose from.

[0003] Chinese patent CN117182669A, authorized and published on December 8, 2023, discloses a fluid polishing device for the inner surface of valve castings, including a polishing mechanism. The polishing mechanism has a polishing cylinder mounted on it for clamping the workpiece to be polished, and permanent magnets are mounted on both sides of the polishing cylinder to drive the magnetic fluid for polishing. In the aforementioned application, when the device is used for polishing parts such as gears that require full-angle polishing, the magnetic fluid flow of the original device cannot cover all angles of the part, easily leading to a decrease in the polishing effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a forging apparatus for metal processing and manufacturing that improves the contact fatigue strength of tooth surfaces, thus solving the problems mentioned in the background art. To achieve the above objectives, this invention provides the following technical solution: a forging apparatus for metal processing and manufacturing that improves the contact fatigue strength of tooth surfaces, comprising: The box has a control panel on its side, a forging device with forging gears on its front top, a support frame on its rear top, a rotary drive device movably connected inside the box, and a polishing cylinder movably connected to the top of the rotary drive device. An electric push rod is fixedly connected to the top of the support frame, and a hollow rod is fixedly connected to the bottom of the electric push rod. A reciprocating lead screw is movably connected inside the hollow rod, and a motor is fixedly connected to the top of the reciprocating lead screw. A threaded slider is threadedly connected to the outer side of the reciprocating lead screw. The outer side of the threaded slider is slidably connected to the hollow rod through a sliding groove. Multiple spherical grooves are formed on the inner surface of the sliding groove. A guide block is rotatably connected to the outer side of the threaded slider through a rotating shaft. The rotating shaft is movably connected to the guide block through a transmission component. The guide block is designed so that when the equipment is started, the threaded slider moves up and down, causing the guide block to follow the movement of the threaded slider. Simultaneously, the guide block continuously changes its angle, causing the polishing cylinder and the magnetic field generating device to drive the magnetic needles and parts to rotate. This allows the surface of the parts to be polished by the magnetic needles. When the parts are heavy, they cannot be completely polished. The up-and-down movement of the guide block agitates the accumulated parts, ensuring that the parts can be polished from multiple angles by the magnetic needles, resulting in a more thorough polishing process and improved equipment efficiency.

Multiple fixed plates three are fixedly connected to the surface of the guide plate, and a collection plate is fixedly connected between the fixed plates three.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1, please refer to Figures 1-5 A forging apparatus for improving the contact fatigue strength of tooth surfaces in metal processing and manufacturing, comprising: The enclosure 100 has a control panel 200 on its side, which functions as a control device. A forging press 300 with forging gears is located on the top front side of the enclosure 100. A support frame 400 is located on the top rear side of the enclosure 100. A rotary drive 800 is movably connected inside the enclosure 100, driving a magnetic field generating device 600 to rotate. A polishing cylinder 700 is movably connected to the top of the rotary drive 800, allowing parts to be polished. The polishing cylinder 700 is polished inside. A fixed device 500 is movably connected to the top of the rotary drive device 800. The fixed device 500 is set to fix the polishing cylinder 700. A magnetic field generating device 600 is fixedly connected to the top of the fixed device 500. The magnetic field generating device 600 is set to rotate with the rotary drive device 800, thereby forming a changing magnetic field. A turbulence assembly 1000 is movably connected to the outside of the hollow rod 902. An impurity collection assembly 1100 is fixedly connected inside the turbulence assembly 1000. An electric push rod 901 is fixedly connected to the top of the support frame 400. A hollow rod 902 is fixedly connected to the bottom of the electric push rod 901. A reciprocating screw 905 is movably connected inside the hollow rod 902. The reciprocating screw 905 is set to make the threaded slider 904 move up and down reciprocally. A motor is fixedly connected to the top of the reciprocating screw 905. The threaded slider 904 is threadedly connected to the outside of the reciprocating screw 905. The outside of the threaded slider 904 is slidably connected to the hollow rod 902 through a sliding groove 903. Multiple spherical grooves are opened on the inner surface of the sliding groove 903. The outside of the threaded slider 904 is rotatably connected to a guide block 906 through a rotating shaft 907. The rotating shaft 907 is movably connected to the guide block 906 through a transmission component. The transmission components include push block 908, hydraulic block 909, hose 910, hydraulic block 911, push block 912, and rotating block 913. The top of the threaded slider 904 is fixedly connected to hydraulic block 909. The front side of hydraulic block 909 is movably connected to push block 908. The bottom of hydraulic block 909 is fixedly connected to one end of hose 910. The other end of hose 910 is fixedly connected to the top of hydraulic block 911. The hose 910 is provided so that the inside of hydraulic block 909 communicates with the inside of hydraulic block 911. The outside of hydraulic block 911 is fixedly connected to the inside of threaded slider 904. The bottom of hydraulic block 911 is movably connected to push block 912. The front side of push block 912 is fixedly connected to rotating block 913. The rear side of rotating block 913 is fixedly connected to rotating shaft 907. There are two hollow rods 902, eight sliding grooves 903, and four sliding grooves 903 form a group. The sliding grooves 903 in each group are distributed around the center of the hollow rod 902. There are two threaded sliders 904, two reciprocating screws 905, eight guide blocks 906, four rotating shafts 907, eight push blocks 908, eight hydraulic blocks 909, eight hoses 910, eight hydraulic blocks 911, eight push blocks 912, and eight rotating blocks 913. The guide block 906 is set up so that when the equipment is turned on, the threaded slider 904 moves up and down, and the guide block 906 moves up and down with the threaded slider 904. At the same time, the guide block 906 continuously changes its angle, so that the polishing cylinder 700 and the magnetic field generating device 600 drive the magnetic needle and the part to rotate, so that the surface of the part is polished by the magnetic needle. When the part is heavy, it cannot be polished completely. The guide block 906 moves up and down to stir up the accumulated parts, so that the part can be polished by the magnetic needle from multiple angles, thus making the polishing process more thorough and improving the working efficiency of the equipment.

[0021] In use, when the equipment starts working and the die-cast parts need to undergo the next polishing process, the operator puts a mixture of multiple parts and magnetic fluid into the polishing cylinder 700, activates the magnetic field generating device 600, and causes the magnetic fluid in the polishing cylinder 700 to rotate following the magnetic field, thereby polishing the surface of the parts. At this time, the electric push rod 901 is activated, causing the hollow rod 902 to move downwards. The motor is started, causing the reciprocating screw 905 inside the hollow rod 902 to rotate, causing the threaded slider 904 to move up and down along the sliding groove 903. The guide block 906 follows the threaded slider 904 up and down. Simultaneously, as the threaded slider 904 moves, the push block... When push block 908 contacts the spherical groove, it moves outward, reducing the internal pressure of hydraulic block 909. This pressure is then transmitted through hose 910 to hydraulic block 911, increasing its internal pressure. This causes push block 912 to retract inward, rotating block 913 to follow push block 912, rotating shaft 907, and guide block 906. This allows heavy parts to be polished thoroughly, and guide block 906 moves up and down, agitating the accumulated parts. This ensures that the magnetic needle can polish the parts from multiple angles, resulting in a more thorough polishing process and improved equipment efficiency.

[0022] Example 2, please refer to Figures 1-7 Based on Embodiment 1, the turbulence assembly 1000 includes a push block 3 1001, a spring 1002, a hydraulic block 3 1003, a hose 2 1004, a fixing plate 1005, a hydraulic block 4 1006, a push block 4 1007, a rotating block 2 1008, a rotating shaft 2 1009, a fixing plate 2 1010, and a guide plate 1011. A hydraulic block 3 1003 is fixedly connected to the outer side of the hollow rod 902. A push block 3 1001 is movably connected to the bottom of the hydraulic block 3 1003. A spring 1002 is fixedly connected between the push block 3 1001 and the hydraulic block 3 1003. The spring 1002 allows the push block 3 1001 to automatically reset. The bottom of the hydraulic block 3 1003 is fixedly connected to one end of the hose 2 1004, and the other end of the hose 2 1004 is fixedly connected to the hydraulic block 3 1005. The rear side of block 4 1006 is fixedly connected to a hose 2 1004, so that the interior of hydraulic block 3 1003 communicates with the interior of hydraulic block 4 1006. The outer side of hollow rod 902 is fixedly connected to a fixing plate 2 1010. The rear side of hydraulic block 4 1006 is fixedly connected to the top of fixing plate 2 1010 through fixing plate 1 1005. The front side of hydraulic block 4 1006 is movably connected to push block 4 1007. The front side of push block 4 1007 is fixedly connected to rotating block 2 1008. The interior of fixing plate 2 1010 is rotatably connected to rotating shaft 2 1009. The top of rotating shaft 2 1009 is fixedly connected to the bottom of rotating block 2 1008. The outer side of rotating shaft 2 1009 is fixedly connected to guide plate 1011. The length of guide plate 1011 is less than the length of fixing plate 2 1010. There are eight push blocks 3 1001, and four push blocks 3 1001 form a group. Each group of push blocks 3 1001 is distributed around the center of the hollow rod 902. There are eight springs 1002, two hydraulic blocks 3 1003, eight hoses 2 1004, eight fixing plates 1 1005, eight hydraulic blocks 4 1006, eight push blocks 4 1007, eight rotating blocks 2 1008, eight rotating shafts 2 1009, eight fixing plates 2 1010, and eight guide plates 1011. The turbulence component 1000 is set up so that when the threaded slider 904 moves to the uppermost position during operation, the rotating shaft 1009 rotates, which in turn drives the guide plate 1011 to rotate, thereby generating turbulence in the fluid inside the polishing cylinder 700, thus increasing the polishing efficiency of the magnetic needle and improving the polishing efficiency of the equipment.

[0023] In use, based on Embodiment 1, when the threaded slider 904 moves upward to its highest position, the push block 1001 moves upward, increasing the internal pressure of the hydraulic block 1003. This internal pressure is then transmitted through the hose 1004 to the hydraulic block 1006, increasing the internal pressure of the hydraulic block 1006. This causes the push block 1007 to push outward, rotating the rotating block 1008. The rotating shaft 1009 then rotates with the rotating block 1008, causing the guide plate 1011 to rotate and open. This creates turbulence in the polishing cylinder 700, increasing the polishing efficiency of the magnetic needle and thus improving the overall polishing efficiency of the equipment.

[0024] Example 3, please refer to Figures 1-9 Based on Embodiment 1 and Embodiment 2, the impurity collection assembly 1100 includes a fixing plate 1101, a collection plate 1102, a filter hole 1103, and a collection groove 1104. Multiple fixing plates 1101 are fixedly connected to the surface of the guide plate 1011. The fixing plates 1101 are set so that the collection plate 1102 can be fixed on the surface of the guide plate 1011. The collection plate 1102 is fixedly connected between the fixing plates 1101. The surface of the collection plate 1102 is provided with a filter hole 1103. The filter hole 1103 is provided so that the fine metal impurities generated during the polishing process are filtered out. The aperture of the filter hole 1103 is smaller than the diameter of the magnetic needle. A collection groove 1104 is provided between the guide plate 1011 and the collection plate 1102. The spacing between the three fixing plates 1101 is the same as the length of the collecting plate 1102; An impurity collection component 1100 is provided so that when the guide plate 1011 is rotated and opened, the collection plate 1102 rotates with the guide plate 1011, so that the collection plate 1102 collects the fine metal impurities polished by the magnetic needle in the polishing cylinder 700 through the filter hole 1103 into the collection tank 1104, thereby allowing the magnetic fluid in the equipment to be recycled, extending the service life of the equipment, and protecting the parts from being scratched by impurities.

[0025] In use, based on Embodiment 1 and Embodiment 2, when the guide plate 1011 is rotated and opened, the collection plate 1102 rotates with the guide plate 1011 via the fixing plate 3 1101. The collection plate 1102 collects the fine metal debris generated during the polishing process of the mixed liquid. The metal debris passes through the filter hole 1103 and is stored inside the collection tank 1104. At the same time, since the size of the filter hole 1103 is smaller than the diameter of the magnetic needle in the magnetic fluid, the filter hole 1103 will not collect the magnetic needle into the collection tank 1104. This allows the magnetic fluid in the equipment to be recycled, extending the service life of the equipment and protecting the parts from being scratched by impurities.

[0026] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
