Description

Technical Field

[0001] The invention relates to the technical field of sword forging, in particular to a sword forging device. Background Art

[0002] Swords have evolved from ancient Chinese weapons into collectible artifacts, exercise equipment, and martial arts training tools. Their nature and uses have undergone significant changes with the development of society. In Longquan, Lishui, sword production has been preserved as a cultural product and has gradually entered the industrialization stage.

[0003] Chinese swords are a rare craftsmanship. From raw material to finished product, a sword undergoes numerous processes, including refining, forging, scraping, filing, carving, inlaying, quenching, and grinding. Hammering, an essential step in sword crafting, is also known as forging in modern sword casting. To improve production efficiency, machine forging is often used to replace traditional manual forging. Forging, a combination of forging and stamping, involves applying pressure to a blank using a forging machine's hammer, anvil, punch, or die, causing plastic deformation to achieve the desired shape and size.

[0004] During forging, the entire blank undergoes significant plastic deformation, with a significant amount of plastic flow. In stamping, the blank is shaped primarily by changing the spatial position of its various areas, without significant internal plastic flow. Forging is primarily used to form metal parts, but can also be used to form certain non-metallic materials, such as engineering plastics, rubber, ceramics, bricks, and composite materials.

[0005] Patent document CN218873596U discloses a sword processing and forging machine with noise reduction function. The machine is equipped with a box and a noise reduction plate. The noise reduction plate includes a frame, a protective net and a sound-absorbing cotton. The plate can provide a relatively closed environment for the processing equipment. Not only is the noise effectively absorbed in the closed environment, greatly reducing the degree of equipment noise leakage into the workshop, but also the splashing of debris and dust is avoided, protecting the health of the workers. In addition, the vibration damping device makes the processing and forging machine have a certain noise reduction function, which is less likely to cause discomfort to the workers.

[0006] At the same time, the shock absorbing device includes a mounting seat and a buffer device, the mounting seat is arranged on the buffer device, the mounting seat is provided with a mounting column and a fixing nut, the mounting column is provided with a thread, the fixing nut and the mounting column are connected by a thread, the buffer device includes a device frame and a buffer assembly, the device frame is a cavity structure, the buffer assembly is arranged in the device frame, the buffer assembly includes an adjusting nut, a threaded column, a buffer seat and a buffer spring, the buffer seat is arranged in the device frame, one end of the threaded column is fixedly connected to the buffer seat and the other end passes through the fixing seat and is connected to the adjusting nut by a thread, the buffer spring is sleeved on the threaded column and the two ends are respectively connected to the buffer seat and the fixing seat.

[0007] However, in the process of implementing the above technical solution, it was found that the above technical solution had the following technical problems:

[0008] When the existing sword processing and forging machine with noise reduction function is in use, the buffer component on the shock absorbing device provides buffering during the forging process, thereby achieving the effect of noise reduction. However, in the actual forging process, due to the mutuality of the acting forces, part of the kinetic energy is easily applied to the buffer device in the form of shock absorption and buffering, thereby increasing the kinetic energy loss and reducing the force applied during the sword forging process, affecting the effect and efficiency of removing the internal structure and performance improvement, metal corrosion resistance improvement, and metal structure defects and residual stress during the sword forging process. Summary of the Invention

[0009] In order to overcome the problem that the existing sword processing and forging machines with noise reduction function are prone to cause part of the kinetic energy to act on the buffer device due to the mutuality of the forces during the actual forging process, thereby increasing the kinetic energy loss, reducing the force applied during the sword forging process, and affecting the effect and efficiency of the sword forging process, the embodiment of the present application provides a sword forging device, which is achieved by threading the forging head and the movable rod, and fixing the forging head and the movable rod.

[0018] In one possible implementation, a mounting sleeve is provided at the top of the movable rod, and holding arms are processed on both sides of the mounting sleeve. The two holding arms are movably connected to the inside of the horizontal plate and the hanging plate, and the multiple protective arc plates are located between the bottoms of the two holding arms, and the multiple protective arc plates are independently arranged.

[0019] In one possible implementation, the inner and outer surfaces of both sides of the plurality of protective arc plates are processed with limiting grooves, the two limiting grooves on the two connected protective arc plates are rollingly connected to the same roller, the interior of the roller is processed with an adaptor ring groove, and the two protective arc plates are suspended between the two rollers located on the inner and outer sides of the protective arc plates.

[0020] In one possible implementation, a first support arm is provided on both sides of the roller located on the outer side of the protective arc plate, and a second support arm is provided on both sides of the roller on the inner side of the protective arc plate. The tops of the two second support arms are fixedly connected to the inner ring seat, and the tops of the two first support arms are fixedly connected to the outer ring seat. The outer ring seat and the inner ring seat are coaxially arranged, and the outer ring seat and the inner ring seat are both assembled and connected to the bottom of the hanging plate by bolts. There are multiple rollers at the bottom of the inner ring seat and the bottom of the outer ring seat, and they respectively correspond to the connection points of multiple protective arc plates.

[0044] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0045] Example 1:

[0046] This embodiment introduces the specific structure of a sword forging device. Figures 1-10 As shown, it includes a forging device frame 1, a double-outlet shaft cylinder 4 arranged on the inner side of the top of the forging device frame 1, and a protective mechanism 3 arranged on the inner side of the bottom of the forging device frame 1 and located directly below the double-outlet shaft cylinder 4. A forging head 5 is provided at the bottom of the double-outlet shaft cylinder 4, and an adapter 9 is provided at the top of the double-outlet shaft cylinder 4. The double-outlet shaft cylinder 4 includes a cylinder seat 401, and a movable rod 402 is slidably connected to the interior of the cylinder seat 401;

[0047] Among them, one end of the movable rod 402 is threadedly connected to the forging head 5, and the other end of the movable rod 402 is threadedly connected to the adapter 9. By threading the forging head 5 and the movable rod 402, the forging head 5 and the movable rod 402 are connected and fixed. When the movable rod 402 is controlled by the cylinder seat 401 to work from top to bottom, it can drive the forging head 5 to directly forge the sword, and the kinetic energy conversion efficiency is high.

[0048] like Figure 1 As shown, the forging device frame 1 includes a bottom plate 103, both sides of the top of the bottom plate 103 are assembled and connected with vertical plates 101, one side of the middle part of the two vertical plates 101 is processed with a notch, a workbench 102 is assembled and connected between the bottom inner walls of the notches of the two vertical plates 101, a hanging plate 104 is provided between the middle parts of the vertical plates 101, and a horizontal plate 105 is assembled and connected between the tops of the two vertical plates 101;

[0049] Among them, the hanging plate 104 is located at the top of the notch of the two vertical plates 101, and the inner side of the hanging plate 104 is assembled and fixed to the bottom of the movable rod 402. By assembling the cylinder seat 401 between the two vertical plates 101, when the double-axis oil cylinder 4 controls the cylinder seat 401 to move up and down inside the movable rod 402, one end of the movable rod 402 drives the hanging plate 104 to move between the two vertical plates 101, which can drive the forging head 5 to forge the sword at the bottom, and the other end of the movable rod 402 is movably connected to the inside of the horizontal plate 105;

[0050] Secondly, in order to facilitate the support of the sword, the forging work is completed on the top of the workbench 102, such as Figure 1 and Figure 2 As shown, a receiving groove 6 is processed on one side of the top of the workbench 102, and a loading plate 2 is arranged inside the loading groove 6. By pin-connecting the loading plate 2 to the inside of the workbench 102 from one side of the receiving groove 6, the loading plate 2 can be connected and fixed to the workbench 102, and the sword blank to be processed is placed on the top of the loading plate 2 to be forged. When the loading plate 2 is worn and deformed due to long-term use, it is convenient to replace it, so as to ensure the forging effect of the sword blank.

[0051] Example 2:

[0052] Based on Example 1, this example introduces the specific structure of the protection mechanism 3. The protection mechanism 3 includes multiple protection arc plates 303. Each of the multiple protection arc plates 303 is embedded with a glass plate 311. The top of the movable rod 402 is provided with a mounting sleeve 302. Both sides of the mounting sleeve 302 are processed with a gripping arm 301.

[0053] Among them, multiple protective arc plates 303 are evenly spaced around the forging head 5 and are located between the bottoms of the two holding arms 301. When the cylinder base 401 moves up and down inside the movable rod 402, the two holding arms 301 can be driven by the mounting sleeve 302 to be movably connected to the inside of the cross plate 105 and the hanging plate 104, thereby driving the multiple protective arc plates 303 between the bottoms of the two holding arms 301 to slide up and down;

[0054] When the plurality of protective arc plates 303 are controlled to move toward the bottom and are positioned around the sword blank, the staff can observe the forging conditions through the glass plates 311 on the protective arc plates 303, which is helpful for the staff to adjust the forging conditions of the sword blank;

[0055] like Figure 4-Figure 9 As shown, the inner and outer surfaces of the two sides of the multiple protective arc plates 303 are processed with limit strip grooves 10, and the two limit strip grooves 10 on the two connected protective arc plates 303 are rollingly connected with the same roller 309, and the inside of the roller 309 is processed with an adapting ring groove 12;

[0056] The two rollers 309 located on the inner and outer sides of the protective arc plates 303 restrict the two protective arc plates 303 from moving away from each other through the adapter ring groove 12. The two protective arc plates 303 are suspended between the two rollers 309 on the inner and outer sides of the protective arc plates 303, which can prevent any protective arc plate 303 from falling to the bottom when the two holding arms 301 drive the multiple protective arc plates 303 to move up and down.

[0057] At the same time, multiple protective arc plates 303 are independently provided. When multiple protective arc plates 303 move toward the bottom along with the two holding arms 301 and are blocked by an object, one or more protective arc plates 303 can pause their movement toward the bottom. At this time, the rollers 309 on the relevant protective arc plates 303 roll within the corresponding limiting grooves 10, ensuring that the remaining protective arc plates 303 can continue to move toward the bottom, thereby forming a barrier on the outside of the forged sword.

[0058] In addition, in order to ensure that the two protective arc plates 303 connected to the two holding arms 301 will not be supported on the top of the workbench 102 or the loading plate 2 during the process of the holding arms 301 being controlled by the movable rod 402 to move up and down, affecting the movable rod 402 to drive the forging head 5 to forge the sword towards the bottom, such as Figure 4 and Figure 5 As shown, one end of each of the two embracing arms 301 is assembled and connected to a support slide 304. The outer surfaces of two of the multiple protective arc plates 303 are formed with a limiting slide 305. By symmetrically arranging the two limiting slides 305 and making the limiting slides 305 suspended inside the support slide 304 and sliding up and down inside the support slide 304, when the two embracing arms 301 move toward the top, the supporting slide 304 can be used to drive the limiting slide 305 to move toward the top, and the movable rod 402 can be used to drive the hanging plate 104, so that the multiple rollers 309 at the bottom of the hanging plate 104 drive the multiple protective arc plates 303 to move toward the top, maintaining the suspended state.

[0059] When the holding arm 301 is controlled by the movable rod 402 to move toward the bottom, the bottom of the protective arc plate 303 with the limiting slide 305 contacts the workbench 102 or the loading plate 2, and the supporting slide 304 slides toward the bottom outside the limiting slide 305.

[0060] Secondly, in order to ensure the suspension effect of the multiple rollers 309 on the multiple protective arc plates 303, as shown in FIG. Figure 4 、 Figure 6 and Figure 7As shown, first support arms 308 are provided on both sides of the roller 309 located on the outer side of the protective arc plate 303, and second support arms 310 are provided on both sides of the roller 309 on the inner side of the protective arc plate 303. The tops of the two second support arms 310 are fixedly connected to the inner ring seat 306, and the tops of the two first support arms 308 are fixedly connected to the outer ring seat 307. There are multiple rollers 309 at the bottom of the inner ring seat 306 and the bottom of the outer ring seat 307, and they correspond to the joint points of the multiple protective arc plates 303 respectively. By making the outer ring seat 307 and the inner ring seat 306 coaxially arranged, the outer ring seat 307 and the inner ring seat 306 are assembled and connected to the bottom of the hanging plate 104 by bolts, and the outer ring seat 307 and the inner ring seat 306 can be used to support the rollers 309 at the bottom of the multiple first support arms 308 and the second support arms 310, so that the multiple rollers 309 can stably support the multiple protective arc plates 303.

[0061] Furthermore, in order to facilitate the upward and downward movement of the oil cylinder seat 401 inside the movable rod 402, the holding arm 301 can be stably driven to move upward and downward. Figure 3 As shown, the top of the adapter 9 is threadedly connected to the limit sleeve 7, and control rods 8 are processed on both sides of the limit sleeve 7. By making the erection sleeve 302 sleeve-connected to the outside of the adapter 9, when the limit sleeve 7 is threadedly connected to the outside of the adapter 9, the erection sleeve 302 can be fixed between the limit sleeve 7 and the adapter 9;

[0062] Furthermore, in order to improve the noise blocking effect of the plurality of protective arc plates 303 during the sword forging process, as Figure 9 As shown, the inner surfaces of the plurality of protective arc plates 303 are fixedly connected with sound-absorbing cotton 13. By making the sound-absorbing cotton 13 sleeve-connected to the outside of one side of the glass plate 311, when the sound generated during the sword forging process is transmitted to the surroundings, it can be blocked by the ring formed by the plurality of protective arc plates 303 and absorbed by the plurality of sound-absorbing cotton 13.

[0063] At the same time, in order to prevent the multiple protective arc plates 303 from colliding with the top of the workbench 102 or the loading plate 2 and generating a large noise when the two holding arms 301 drive the multiple protective arc plates 303 to move to the bottom. Figure 9 As shown, the bottoms of the multiple protective arc plates 303 of the cylinder seat 401 are all connected with protective sleeves 11 in a sleeve-type manner. By adding the protective sleeves 11 at the bottoms of the protective arc plates 303, when they move toward the bottom, they can be protected by the protective sleeves 11 to avoid generating loud noise.

[0064] Specifically, when the sword forging device is used to forge a sword blank:

[0065] First, the carrier plate 2 is pinned to the inside of the workbench 102 through one side of the receiving groove 6, thereby fixing the carrier plate 2 to the workbench 102, and the sword blank to be processed is placed on the top of the carrier plate 2 to wait for forging;

[0066] Then, the double-outlet shaft cylinder 4 is started, so that the movable rod 402 on the double-outlet shaft cylinder 4 moves inside the cylinder seat 401. When the movable rod 402 moves toward the top inside the cylinder seat 401, on the one hand, the bottom of the movable rod 402 drives the forging head 5 away from the carrier plate 2, and drives the outer ring seat 307 and the inner ring seat 306 to move toward the top with the help of the hanging plate 104, so that the multiple rollers 309 between the multiple first support arms 308 and the multiple second support arms 310 are in the limiting grooves 10 on the two adjacent protective arc plates 303, pulling the multiple protective arc plates 303 to move toward the top synchronously, exposing the top of the carrier plate 2 to the staff's field of vision, so that the staff can load and unload sword blanks on the top of the carrier plate 2;

[0067] At the same time, the top of the movable rod 402 drives the two holding arms 301 to move toward the top through the adapter 9 and the mounting sleeve 302. The protective arc plates 303 connected to the two holding arms 301 through the limiting slide 305 and the supporting slide 304 are respectively suspended on the top of the supporting slide 304 by means of the limiting slide 305. The suspension height is the same as the height at which the corresponding roller 309 suspends the protective arc plates 303.

[0068] Next, the heated and softened sword blank is placed on top of the loading plate 2, and the double-outlet oil cylinder 4 is activated, causing the movable rod 402 to move from top to bottom inside the oil cylinder seat 401. The bottom of the movable rod 402 drives the forging head 5 toward the sword blank, and the hanging plate 104 drives the multiple first support arms 308 and second support arms 310 toward the bottom through the inner ring seat 306 and the outer ring seat 307. The protective arc plate 303 suspended by the multiple rollers 309 moves toward the bottom due to its own gravity, forming a barrier on the outside of the sword blank.

[0069] During this process, if the tongs holding the sword blank block one or more protective arc plates 303, the one or more protective arc plates 303 can stop moving toward the bottom, and the corresponding rollers 309 on the protective arc plates 303 roll inside the corresponding limiting grooves 10, ensuring that the remaining protective arc plates 303 can continue to move toward the bottom, forming a barrier on the outside of the forged sword, so that the noise generated by the forging head 5 forging the sword blank is absorbed by the silencer cotton 13 on the inner surface of the protective arc plates 303, and the noise reduction effect can be improved when multiple protective arc plates 303 form a circular blocking ring.

[0070] At the same time, the movable rod 402 moving toward the top drives the two holding arms 301 at the top to move toward the bottom. When the bottom of the protective arc plate 303 connected to it through the supporting slide 304 and the limiting slide 305 contacts the top of the work table 102 or the top of the loading plate 2, the supporting slide 304 continues to slide toward the bottom outside the limiting slide 305, which helps to prevent the protective arc plate 303 from being supported on the surface of the work table 102 or the loading plate 2, affecting the movement of multiple protective arc plates 303 toward the bottom, and forming protection on the outside of the sword blank;

[0071] In addition, by adding a protective cover 11 at the bottom of the protective arc plate 303, when it moves toward the bottom, it can be protected by the protective cover 11, thereby preventing multiple protective arc plates 303 from colliding with the top of the workbench 102 or the loading plate 2 and generating loud noise during the process of moving toward the bottom driven by the two holding arms 301.

[0072] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
