Description

A non-magnetic steel precision forging device and its forging process Technical Field

[0001] This invention relates to the field of non-magnetic steel forging technology, and more specifically, to a non-magnetic steel precision forging device and its forging process. Background Technology

[0002] Non-magnetic steel, especially austenitic stainless steel, is widely used in high-end equipment manufacturing fields such as medical devices, aerospace, marine engineering and energy due to its high strength, high toughness, high corrosion resistance and extremely low magnetic permeability.

[0003] Non-magnetic steel precision forging equipment is a specialized device that uses multiple hammers to synchronously forge billets radially symmetrically and at high frequency. The device typically integrates functional units such as precision guidance, multi-directional synchronous impact, and automatic flipping feeding, enabling precise control over the shape, size, and deformation process of forgings.

[0004] Chinese invention patent application number 202510141217.2 discloses a forging equipment and process for non-magnetic steel parts, including a support block. The support block has a rectangular hole in the middle and an annular groove in the middle. The four corners of the annular groove have circular sliding grooves. A first cylindrical block is slidably connected in the circular sliding groove. A U-shaped block is installed at one end of the first cylindrical block. A cylindrical strip is rotatably connected to the middle of the U-shaped block. A first rectangular block is fixed to the middle of the cylindrical strip. A first extrusion head is fixed to one side of the first rectangular block. A second extrusion head is fixed to the other side of the first rectangular block. By driving the first waist-shaped strip to rotate, the second extrusion head and the first extrusion head are rotated through the cylindrical strip. The positions of the second extrusion head and the first extrusion head are interchanged without disassembly. Different shaped hammer heads can be replaced, solving the problem of the cumbersome disassembly and replacement of hammer heads.

[0005] Although the invention solves the problems of disassembling and replacing hammer heads and the synchronization of hammer heads, the precision forging device mainly relies on high-frequency, low-energy forging in a single mode when forging non-magnetic steel. This makes it difficult for deformation energy to effectively penetrate into the core of the billet, resulting in uneven deformation of the forging cross section. The core is prone to retaining coarse grains and developing internal cracks, causing a serious gradient in structure and properties from the surface to the core, ultimately damaging the overall reliability and service life of the product.

[0006] This invention provides a non-magnetic steel precision forging device and its forging process, aiming to solve the problem that existing precision forging devices rely on a single mode of high-frequency, low-energy forging, which makes it difficult for deformation energy to effectively penetrate into the core of the billet, thus damaging the overall reliability and service life of the product.

[0016] Preferably, the electromagnetic drive assembly includes a first magnetic element embedded in the impact member, a second magnetic element embedded in the fifth piston member, and an electromagnet fixedly disposed and corresponding to the first magnetic element and the second magnetic element, wherein the electromagnet is electrically connected to the controller.

[0017] Preferably, the first piston is fixedly connected to a guide post on the side facing the guide cavity, and the impact member has an oil passage hole for the guide post to be inserted.

[0018] Preferably, the controller is used to control the opening and closing of the electromagnet and the direction of its magnetic poles based on the number of times the hammer strikes.

[0019] Preferably, the clamping mechanism is slidably mounted on the slide rail of the base, and the support frame of the forging mechanism is provided with a material passage hole for the workpiece to pass through, and a plurality of hammers are arranged around the material passage hole.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Existing precision forging equipment mainly relies on high-frequency, low-energy forging in a single mode when forging non-magnetic steel. This makes it difficult for deformation energy to effectively penetrate into the core of the billet, resulting in uneven deformation of the forging cross section. Coarse grains are easily left in the core, and internal cracks are generated, causing a serious gradient in microstructure and properties from the surface to the core, ultimately damaging the overall reliability and service life of the product.

[0041] Referring to Figures 1 to 10, an embodiment of the present invention provides a non-magnetic steel precision forging device, including a base 1, a forging mechanism 2, and a clamping mechanism 3. The forging mechanism 2 is disposed on the base 1, and slide rails 11 are provided on both sides of the top of the base 1. The clamping mechanism 3 is configured as two sets, symmetrically slidably connected to the two slide rails 11. The clamping mechanism 3 is used to clamp the non-magnetic steel and drive the non-magnetic steel to rotate and move axially. Supporting mechanisms 12 are provided on both slide rails 11 for supporting the non-magnetic steel. The clamping mechanism 3 and the supporting mechanism 12 are both prior art and will not be described in detail here.

[0042] Referring to Figures 1, 2, 3 and 6, the forging mechanism 2 includes a support frame 21 fixedly connected to the top of the base 1. The support frame 21 has a through-hole 22. Four cylinders 23 are fixedly connected to the support frame 21 at equal intervals. Each cylinder 23 has a hydraulic chamber 24 inside. Each hydraulic chamber 24 has a first piston 25 slidably connected inside. Each first piston 25 has a piston rod 26 fixedly connected to the side near the through-hole 22. Each piston rod 26 has a hammer head 27 for forging non-magnetic steel fixedly connected to one end extending from the hydraulic chamber 24.

[0043] Referring to Figures 2 and 3, each cylinder 23 is provided with a first oil port 28 and a second oil port 29 that communicate with the corresponding hydraulic chamber 24. The first oil port 28 and the second oil port 29 are respectively located at both ends of the hydraulic chamber 24 and are both connected to an external oil supply device for hydraulic oil to enter the hydraulic chamber 24 and drive the first piston 25 to reciprocate within the hydraulic chamber 24.

[0044] Referring to Figures 2 to 9, the system also includes a heavy-pressure mechanism 4 disposed within each cylinder 23. The heavy-pressure mechanism 4 includes a guide cavity 41 disposed inside the cylinder 23 and communicating with the interior of the hydraulic cavity 24. The guide cavity 41 is located at the end of the hydraulic cavity 24 away from the material passage 22. The diameter of the guide cavity 41 is smaller than that of the hydraulic cavity 24. An impact member 42 is slidably connected inside the guide cavity 41. A plurality of uniformly distributed first magnetic members 43 are fixedly embedded on the side of the impact member 42 away from the hydraulic cavity 24. An electromagnet 44, which is the same number as the first magnetic members 43 and corresponding in position, is fixedly embedded at the end of the guide cavity 41 away from the hydraulic cavity 24.

[0045] Referring to Figures 6 and 7, the impact member 42 is provided with an oil passage hole 423 for reducing fluid resistance during movement. The first piston member 25 is fixedly connected to a guide post 424 on the side near the guide cavity 41. The guide post 424 can be inserted into the oil passage hole 423 to guide the impact member 42. The guide post 424 is hollow and has multiple through-holes 425 on its outer wall.

[0046] Referring to Figure 5, the cylinder body 23 is provided with a first adjustment chamber 45 and a second adjustment chamber 46. A first channel 47 is provided between the first adjustment chamber 45 and the hydraulic chamber 24, and a second channel 48 is provided between the second adjustment chamber 46 and the hydraulic chamber 24. The first channel 47 and the second channel 48 are respectively provided at both ends of the hydraulic chamber 24.

[0047] A second piston 49 is slidably connected inside the first adjusting cavity 45. A first elastic element 410 is connected between the side of the second piston 49 away from the hydraulic cavity 24 and the first adjusting cavity 45. A third piston 411 is slidably connected inside the second adjusting cavity 46. A second elastic element 412 is connected between the side of the third piston 411 away from the hydraulic cavity 24 and the second adjusting cavity 46.

[0048] Referring to Figures 5 and 9, the cylinder body 23 has a first sealing groove 413 that penetrates the first channel 47 and a second sealing groove 414 that penetrates the second channel 48. Both the first sealing groove 413 and the second sealing groove 414 are slidably connected to a sealing element 415. The two sealing elements 415 are symmetrically arranged and each of the two sealing elements 415 has a connecting hole 416. A fourth piston element 417 is fixedly connected to the side of the two sealing elements 415 that are close to each other. A driven cavity 418 is formed between the first sealing groove 413 and the second sealing groove 414.

[0049] Referring to Figures 3, 4, and 8, a drive chamber 419 is provided inside the cylinder body 23. The drive chamber 419 is located on the side of the plurality of electromagnets 44 away from the guide chamber 41. The drive chamber 419 is filled with hydraulic oil. A fifth piston 420 is slidably connected inside the drive chamber 419. A plurality of evenly distributed second magnetic elements 421 are fixedly embedded on the fifth piston 420. Each second magnetic element 421 corresponds to one of the electromagnets 44. The driven chamber 418 and the drive chamber 419 are connected by a hydraulic pipe 422. The first magnetic element 43 and the second magnetic element 421 can be permanent magnets.

[0050] Electromagnet 44 is electrically connected to the controller, which controls the opening and closing of electromagnet 44 and the direction of its magnetic poles according to the preset number of forging times of hammer 27.

[0051] In actual operation, the non-magnetic steel is first sent to the clamping mechanism 3 by an external robotic arm, and then the clamping mechanism 3 is driven to move on the slide rail 11 to clamp the non-magnetic steel.

[0052] After clamping, the drive clamping mechanism 3 moves the non-magnetic steel along the slide rail 11 toward the forging mechanism 2, so that the non-magnetic steel enters the material passage hole 22 and is located between the four hammers 27. During the movement of the non-magnetic steel, the support mechanism 12 can be controlled according to the length of the non-magnetic steel to support the non-magnetic steel workpiece.

[0053] Then, the external oil supply device is activated to supply oil to the four hydraulic chambers 24, pushing the first piston 25 to reciprocate within the corresponding hydraulic chamber 24. This, in turn, drives the four hammers 27 to perform high-frequency forging of the non-magnetic steel in the material passage 22 via the piston rod 26. During the forging process, the clamping mechanism 3 can clamp the non-magnetic steel for rotation and feeding to adjust the forging position and achieve uniform forming.

[0054] During the high-frequency forging of non-magnetic steel by hammer 27, when the number of forgings reaches the set threshold, as the first piston 25 moves toward the material passage 22, the controller controls the electromagnet 44 to generate a magnetic force that is repulsive to the first magnetic component 43 and the second magnetic component 421.

[0055] The repulsive force between the electromagnet 44 and the first magnetic component 43 pushes the impact component 42 to move rapidly toward the first piston component 25 within the guide cavity 41, and impacts the first piston component 25 before it reaches its limit position. This impact force accelerates the first piston component 25, allowing the hammer head 27 to obtain greater forging pressure, thus enabling heavy hammer processing of non-magnetic steel. This allows the device to intelligently trigger intermittent high-intensity heavy impacts during continuous high-frequency precision forging. This composite process mode of high-frequency hammering and intermittent heavy pressure breaks the limitations of single-energy forging. The high-energy impact can effectively drive deformation to penetrate into the core of the billet, significantly improving the deformation uniformity of the forging cross section, thereby obtaining a fine and uniform grain structure from the surface to the core, fundamentally avoiding the generation of coarse grains and internal cracks in the core.

[0056] Simultaneously, the repulsive force between the electromagnet 44 and the second magnetic component 421 pushes the fifth piston component 420 to move away from the guide cavity 41, pressing the hydraulic oil in the guide cavity 41 into the driven cavity 418 through the hydraulic pipe 422. The hydraulic oil in the driven cavity 418 pushes the two fourth piston components 417, causing them to move away from each other and drive the corresponding sealing components 415, thereby aligning the two connecting holes 416 with the first channel 47 and the second channel 48 respectively, so that the first adjusting cavity 45 and the second adjusting cavity 46 are connected to the hydraulic cavity 24.

[0057] Since the impact of the impact member 42 on the first piston member 25 will accelerate its movement speed, the oil supply and return speed of the external oil supply device may not be matched in time. At this time, the second piston member 49 in the first adjustment chamber 45 is pulled and stretches the first elastic member 410, so that the hydraulic oil in the first adjustment chamber 45 is replenished to the hydraulic chamber 24 on the side of the first piston member 25 away from the feed hole 22.

[0058] Simultaneously, the third piston 411 in the second regulating chamber 46 is pressed and compresses the second elastic element 412, causing excess hydraulic oil in the hydraulic chamber 24 near the material passage 22 of the first piston 25 to temporarily flow into the second regulating chamber 46 for storage. This effectively adapts to the accelerated movement of the first piston 25, avoiding pressure fluctuations or system instability caused by untimely oil flow. By dynamically and quickly adjusting the oil volume at both ends of the hydraulic chamber 24, the flow difference caused by the instantaneous acceleration of the first piston 25 is compensated in a timely manner, effectively buffering the pressure shock and fluctuation of the system. This ensures the pressure stability of the entire hydraulic system under heavy pressure, avoids interference with the precision high-frequency forging rhythm, and achieves a smooth and stable switching between heavy pressure mode and precision forging mode, ensuring the reliability of the continuous forging process.

[0059] After the first piston 25 moves to its limit position, the external oil supply device continues to circulate oil, so that the pressure in the hydraulic chamber 24 gradually recovers. After the pressure is recovered, the first elastic element 410 and the second elastic element 412 respectively drive the second piston 49 and the third piston 411 back to their initial positions.

[0060] It should be noted that when the impact member 42 moves from the guide cavity 41 into the hydraulic cavity 24, the guide post 424 can be inserted into the oil passage 423 to continue guiding the impact member 42. Through the alternating guidance of the guide cavity 41 and the guide post 424, the impact member 42 is effectively prevented from deviating during the movement, ensuring the accuracy and reliability of the impact action.

[0061] After the hammer is completed, as the external oil supply device drives the first piston 25 to move away from the feed hole 22, the first piston 25 will drive the impact member 42 to retract synchronously. At the same time, the controller controls the electromagnet 44 to generate a magnetic force that attracts the first magnetic member 43 and the second magnetic member 421 with opposite polarities.

[0062] When the first piston 25 drives the impact member 42 back to its limit position, the attraction between the electromagnet 44 and the first magnetic member 43 pulls the impact member 42 back to its initial position; the attraction between the electromagnet 44 and the second magnetic member 421 drives the fifth piston 420 back to its initial position, creating a negative pressure in the drive chamber 419, thereby drawing back the hydraulic oil in the driven chamber 418 through the hydraulic pipe 422. During the process of drawing back the hydraulic oil, the two sealing members 415 will move closer to each other, re-sealing the first channel 47 and the second channel 48, preparing for the next heavy hammer impact, so that the heavy pressure mechanism 4 does not affect the normal forging process of the hammer head 27 when it is not inactive.

[0063] Furthermore, the controller can be set to execute the heavy hammer once before and once after the local forging of non-magnetic steel. The heavy hammer before forging can initially compact the billet, improve the uniformity of material density, and lay the foundation for subsequent uniform deformation. At the same time, the high-energy impact vibration generated by the heavy hammer helps to loosen and peel off the oxide scale on the surface of the billet, and improve the surface quality of the forging.

[0064] The strong stress wave generated by the heavy hammer after forging can promote the rearrangement and recovery of dislocations in the post-forging microstructure, help release residual stress, stabilize the microstructure, and improve the comprehensive mechanical properties of the material.

[0065] In summary, by setting up the heavy-pressure mechanism 4, on the one hand, when the number of forgings reaches the threshold, the impact member 42 can apply an impact acceleration to the first piston member 25, significantly increasing the instantaneous forging pressure of the hammer head 27, realizing the heavy hammer processing of non-magnetic steel. Through the coordination of the first adjustment chamber 45, the second adjustment chamber 46 and the second piston member 49, the third piston member 411 and the first elastic member 410, the second elastic member 412 within them, the hydraulic oil flow can be adaptively adjusted to ensure the system pressure is stable when the first piston member 25 accelerates its movement. On the other hand, the heavy hammers that can be triggered before and after forging can both compact and homogenize the material and shake off the oxide scale before forging to improve the subsequent forging quality, and promote the reorganization and recovery of the material's lattice dislocations after forging, thereby significantly improving the mechanical properties and long-term structural stability of the forging area of ​​non-magnetic steel.

[0066] Example 2

[0068] S1. Place the non-magnetic steel billet in the clamping mechanism 3 and transfer it to the forging station of the forging mechanism 2;

[0069] S2. Start the forging mechanism 2, drive multiple hammers 27 to perform high-frequency synchronous forging of the billet, and adjust the angle and feed of the billet through the clamping mechanism 3 during the forging process;

[0070] S3. During the high-frequency synchronous forging process, when the number of forging times reaches the preset threshold, the heavy pressure mechanism 4 is triggered, so that the hammer 27 applies heavy pressure to the billet for forging.

[0071] S4. Repeat steps S2 and S3 until the overall forging of the billet is completed.

[0072] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
