Description

Technical Field

[0001] This invention relates to the technical field of mechanical forging, and in particular to a forging machine and forging method for metal products. Background Technology

[0002] Metal forging, a time-honored plastic forming process, is an indispensable core technology in modern manufacturing. With the rapid development of strategic emerging industries such as aerospace, high-end equipment, and new energy vehicles, the performance requirements for metal components are becoming increasingly stringent. Components not only need to possess high strength, high toughness, and excellent fatigue performance, but their geometries are also becoming increasingly complex, exhibiting characteristics such as multiple curved surfaces, deep cavities, and asymmetry. For example, aircraft engine turbine disks, aircraft landing gear load-bearing components, and integrated chassis components for new energy vehicles all place urgent demands on precision, multi-directional, and integral forging technologies.

[0003] In existing technologies, to address the multi-directional forging needs of complex workpieces, the industry generally adopts two main solutions. The first type uses traditional single-action or double-action hydraulic forging machines in conjunction with multiple sets of specialized dies. Its basic structure typically includes a fixed lower worktable and an upper movable crossbeam driven by a main hydraulic cylinder. The working principle is as follows: the heated billet is placed into the lower die cavity, and the upper crossbeam descends to complete one closed-die forging operation. If the workpiece needs to be forged from different directions, such as rough forging followed by partial upsetting, the workpiece must be removed from the die, repositioned, clamped, or even transferred to another machine or another set of dies for subsequent processes. This working method has significant limitations: repeated heating and cooling cycles easily lead to severe oxidation and decarburization of the workpiece surface, coarsening of the grain structure, and severely affect the final mechanical properties; repeated clamping and positioning operations introduce unavoidable repetitive positioning errors, resulting in decreased part contour accuracy, uneven allowances, and a huge amount of subsequent machining; furthermore, high equipment and die investment, long production cycles, and high energy consumption severely restrict the production efficiency and cost control of high-end complex forgings.

[0004] The second type of solution involves using a multi-directional forging press or a multi-hammer linkage forging machine with a certain angle adjustment function. This type of equipment typically has a vertical main cylinder and multiple horizontal side cylinders, which can simultaneously or sequentially apply pressure to the blank within the die from several fixed directions. Its structure and working principle are as follows: a main working cylinder is located in the center of a large, enclosed frame, with horizontal auxiliary working cylinders integrated on the sides of the frame. The die system design is complex, often including modular die blocks that can be separated. During operation, the blank is placed in the center, the main cylinder performs vertical compression, and simultaneously or sequentially drives the side cylinders to perform horizontal extrusion, achieving the forming of features such as branches and cavities. However, this type of equipment has several fundamental problems: First, its multi-directional capability is fixed and limited; the impact direction is usually limited to a preset orthogonal direction, making it difficult to forge inclined surfaces, resulting in a severe lack of process flexibility. Second, the actuators and support structures of the side working cylinders are directly integrated into the large and expensive integral frame, making their angle and position difficult to adjust. To forge a part with a non-orthogonal inclined plane, an extremely complex and expensive inclined plane mold needs to be designed to correct the direction of the force. At the same time, the overall structure of the equipment is relatively large and the manufacturing cost is high, and the complexity and cost of mold design, manufacturing and maintenance are also multiplied.

[0051] The present invention will be further described in detail below with reference to the accompanying drawings.

[0052] Please see Figure 1-5This invention discloses a forging machine for metal products, comprising a rectangular base 1. The base 1 can be made of high-rigidity cast iron or welded steel structure, and its bottom can be equipped with multiple leveling feet to adjust according to the flatness of the installation surface, ensuring the stability of the equipment during operation. The upper surface of the base 1 is milled, providing high flatness and levelness, thus providing a reliable mounting reference for the moving parts above it.

[0053] A forging table 2 is mounted on the upper surface of the base 1. This forging table 2 is primarily used to place and clamp the workpiece to be forged. The forging table 2 is rotatably mounted at the center of the base 1 via a large slewing bearing. This slewing bearing has high axial and radial load-bearing capacity, allowing the forging table 2 to rotate around a vertical axis under the drive of a drive device (not shown in the figure). Several clamping stations are evenly arranged along the circumference of the upper surface of the forging table 2, each station equipped with a set of clamping components 21. Each clamping component 21 includes a clamping column 211 vertically fixed to the forging table 2. The clamping column 211 is generally made of high-strength alloy steel, and a clamping cylinder 212 is mounted on its top. The clamping cylinder 212 is preferably a double-acting hydraulic cylinder or a pneumatic cylinder. When the workpiece is placed in the central area of ​​the forging table 2, the control system can instruct all clamping cylinders 212 to operate synchronously, causing the jaws to firmly clamp the workpiece from all sides, preventing it from shifting or lifting during the forging process. The rotating function of the forging table 2 allows the workpiece to undergo forging from different directions after a single clamping, eliminating the need for repeated disassembly and repositioning, which greatly improves processing efficiency and accuracy.

[0054] Located directly above the forging table 2 is the upper forging table 3, which is driven by an upper drive mechanism 31 and can move vertically relative to the forging table 2. The upper drive mechanism 31 mainly consists of several upper sliding columns 31 firmly installed at the four corners of the upper end face of the base 1. The upper sliding columns 31 are guide rods with hardened surfaces, and their axes are perpendicular to the upper plane of the base 1. The tops of all the upper sliding columns 31 are connected as one unit by an upper support platform 32, forming a gantry frame structure. An upper drive cylinder 33 is installed on the upper support platform 32. This cylinder is preferably a large-stroke, high-thrust servo hydraulic cylinder. Its cylinder body is fixed to the upper support platform 32, and its piston rod extends downward and is rigidly connected to the top center of the upper forging table 3. The upper forging table 3 is equipped with linear bearings or sliding bushings, which form a sliding pair with the upper sliding columns 31 to ensure that the upper forging table 3 moves smoothly and without jamming during the lifting and lowering process, and can withstand a large off-center load torque. By controlling the extension and retraction of the upper drive cylinder 33, the vertical distance between the upper forging table 3 and the workpiece on the forging table 2 can be precisely adjusted, thereby adapting to the forging requirements of workpieces of different heights and reserving space for the feeding of forging tools on the upper forging table 3.

[0055] Specifically, a slant forging table 4 is rotatably connected to the side of the upper forging table 3. The slant forging table 4 is generally plate-shaped and located diagonally above the forging table 2. Furthermore, a side forging table 5 is fixedly connected to the slant forging table 4, and the side forging table 5 can be fixed to the slant forging table 4 by bolts or welding. The side forging table 5 is located to the side of the forging table 2. Thus, the upper forging table 3, the slant forging table 4, and the side forging table 5 spatially constitute a hammering platform capable of simultaneously forging workpieces from above, diagonally above, and from the side. To perform the forging operation, at least one forging cylinder 6 is installed on the lower surface of the upper forging table 3, the workpiece-facing surface of the slant forging table 4, and the workpiece-facing surface of the side forging table 5. The forging cylinder 6, as the final forging actuator, has its piston rod detachably connected to various types of hammers, punches, or dies. The forging cylinder 6 can be a high-speed, high-frequency response hydraulic cylinder equipped with a precision servo valve to achieve precise control of forging force and impact speed.

[0056] At least one set of rotating connectors 7 are provided between the inclined forging table 4 and the upper forging table 3. Each set of rotating connectors 7 includes an outer sleeve 71 installed on the side of the upper forging table 3 and an inner sleeve 72 installed at the corresponding position on the inclined forging table 4. The inner sleeve 71 is a hollow cylindrical cavity, and the inner sleeve 72 is coaxially fitted inside the outer sleeve 71. The two are dynamically sealed by a high-performance sealing ring, allowing the inner sleeve 72 to slide axially within the outer sleeve 71 and swing relative to it within a certain angle. This sleeve-type hinge structure not only provides a rotation center, but the sealed chamber formed inside also constitutes an angle locking and buffering system. The outer sleeve 71 is connected to a balancing component 73 through a pipeline. The balancing component 73 is also a hollow container with an opening on one side. An adjusting component 74 is installed in the opening of the balancing component 73 in a sliding fit and can move axially. A seal is also provided between the adjusting component 74 and the inner wall of the balancing component 73. The balancer 73 is also equipped with a locking member 75 to limit the slippage of the adjusting member 74. In a preferred embodiment, a locking plate 731 is welded or integrally formed on the outer wall of the balancer 73. The locking plate 731 has a threaded hole, and the locking member 75 is a locking bolt that passes through the threaded hole of the locking plate 731, with its end abutting against the side of the adjusting member 74. When the locking bolt is rotated inward until it tightly abuts against the adjusting member 74, the adjusting member 74 can be fixed in the current position by friction.

[0057] The working principle of this rotary connection and locking system is as follows: When the angle of the inclined forging table 4 needs to be adjusted, it is driven to rotate around the hinge axis. This rotation forces the inner sleeve 72 to produce an axial relative displacement within the outer sleeve 71, thereby changing the volume of the sealed chamber inside the outer sleeve 71. When the inclined forging table 4 rotates in one direction, the volume decreases; when it rotates in the opposite direction, the volume increases. Since the outer sleeve 71 is connected to the balancer 73, their internal chambers together form a communicating vessel system. The chamber can be pre-filled with a liquid of a certain viscosity, such as hydraulic oil or special damping grease, and most of the air is removed. When the chamber volume changes, the internal liquid pressure changes. In order to balance the pressure and maintain a basic equilibrium with the external atmospheric pressure, the adjusting member 74 in the balancer 73 is pushed to slide along the opening. When the volume decreases, the adjusting member 74 is pushed out to increase the overall volume; when the volume increases, the external atmospheric pressure or spring force pushes the adjusting member 74 in to decrease the overall volume. This process provides controllable damping for the rotation of the inclined forging table 4, making its rotation smooth and shock-free. Once the slant forging table 4 has rotated to the required angle, the operator or the control system automatically tightens the locking bolts, causing the locking element 75 to firmly press against the adjusting element 74. Since the adjusting element 74 is fixed at this point, the volume within the balancing element 73 is fixed, and consequently, the volume inside the outer sleeve 71 is also locked through the fluid connection. The inner sleeve 72 can no longer move axially, thus firmly locking the angle of the slant forging table 4 in its current state. The filling fluid not only increases system damping, making angle adjustment smoother, but the near-incompressible nature of the fluid also makes the angle locking achieved through the locking adjusting element 74 extremely stable, resisting the enormous reverse torque generated during forging and ensuring the positional accuracy and rigidity of the slant forging table 4 during impact. Furthermore, the system also has a certain overload protection function. If unexpectedly subjected to abnormal external force, a sudden increase in fluid pressure can be released through a preset safety valve to prevent structural damage.

[0058] To achieve automated drive and control of the rotation of the slant forging table 4, a rotary cylinder 34 is also installed on the upper forging table 3. A side mounting plate 8441 is fixed on the slant forging table 4, and a driven column 411 is mounted on the side mounting plate 8441. A transmission rod 412 is connected between the piston rod end of the rotary cylinder 34 and the driven column 411. The two ends of the transmission rod 412 are hinged to the piston rod end and the driven column 411 respectively through ball joints or universal joints. This connection method allows for certain positional changes during the drive process. When the rotary cylinder 34 extends or retracts, it pushes or pulls the driven column 411 through the transmission rod 412, thereby providing a rotational torque to the slant forging table 4 about its hinge point with the upper forging table 3, realizing automatic and precise adjustment of the angle of the slant forging table 4. The rotary cylinder 34, along with the upper drive cylinder 33, clamping cylinder 212, etc., can be powered by a central hydraulic station or air source system and controlled collaboratively by a PLC or CNC system.

[0059] To further increase the flexibility and coverage of forging, a transverse movement assembly 8 is integrated on both the slant forging table 4 and the side forging table 5. The mounting plate 84 for installing the forging cylinder 6 can be adjusted horizontally. Taking the transverse movement assembly 8 on the slant forging table 4 as an example: the transverse movement assembly 8 mainly includes a transverse movement drive 81, a transverse movement screw 82, a transverse movement plate 83, and a mounting plate 84. The transverse movement drive 81 is mounted on the side wall of the slant forging table 4. The transverse movement screw 82 is rotatably connected to the slant forging table 4 via a bearing seat, and its axis is parallel to the direction of transverse movement required on the slant forging table 4. The output end of the transverse movement drive 81 is connected to the transverse movement screw 82 via a coupling, driving it to rotate in both directions. The transverse movement plate 83 engages with the transverse movement screw 82 through its threaded hole, forming a screw-nut pair. To ensure the linear accuracy of the movement of the transverse plate 83 and prevent it from rotating with the lead screw, a first sliding groove 42 is machined on the surface of the inclined forging table 4. The transverse plate 83 is embedded in the first sliding groove 42 and can slide along it. For further guidance, at least one parallel guide rod 85 is fixedly installed on the side wall of the first sliding groove 42, and a matching guide groove 831 is opened on the transverse plate 83, through which the guide rod 85 passes, ensuring the smoothness and torsional resistance of the movement of the transverse plate 83. With this structure, the transverse plate 83 can move precisely in a straight line along the first sliding groove 42 under the drive of the transverse drive member 81.

[0060] Mounting plate 84 is used to directly mount forging cylinder 6, and its connection with transverse plate 83 provides additional degrees of freedom for angle adjustment. Specifically, transverse plate 83 extends into mounting bracket 832 by bending. An adjusting cylinder 84 is mounted on each side of transverse lead screw 82 via a hinge shaft on mounting bracket 832. The piston rod ends of the two adjusting cylinders 84 are hinged to two points on the back of mounting plate 84. Simultaneously, the bottom or center area of ​​mounting plate 84 is connected to transverse plate 83 via a hinge shaft, allowing mounting plate 84 to swing around this hinge shaft. By coordinating the extension and retraction of the two adjusting cylinders 84, the pitch angle of mounting plate 84 can be precisely adjusted around its hinge point with transverse plate 83. In this way, the attack angle of forging cylinder 6 and its hammer, fixed on mounting plate 84, can be finely adjusted in a direction perpendicular to the plane of inclined forging table 4, ensuring that the hammer contacts the workpiece surface at the optimal angle.

[0061] The transverse movement assembly 8 on the side forging table 5 is structurally and functionally similar to that on the inclined forging table 4. It also includes a transverse movement drive 81, a transverse movement screw 82, a transverse movement plate 83, and an angle-adjustable mounting plate 84. Its guiding structure consists of a second sliding groove 51 on the side forging table 5 and guide rods 85 on the sidewall of the second sliding groove 51, which cooperate with the guide groove 831 on the transverse movement plate 83. This allows the forging cylinder 6 on the side forging table 5 to also perform precise horizontal position adjustments and independent adjustment of the attack angle.

[0062] This invention also discloses a forging method for metal articles, using the aforementioned forging machinery, including,

[0063] S1, clamp the workpiece.

[0064] The operator or automated loading and unloading mechanism places the metal workpiece to be forged, such as a billet or preform, in the central area of ​​the forging table 2. Then, the clamping system is activated, and all clamping cylinders 212 move synchronously, driving the grippers to reliably clamp the workpiece from all sides. It should be understood that the clamping force of the clamping cylinders 212 can be preset and adjusted according to the workpiece material and the magnitude of the forging force.

[0065] S2, initially positioned on forging platform 3.

[0066] Based on the initial height of the workpiece and the requirements of the first forging process, the control system instructs the drive cylinder 33 to lower the upper forging table 3 to a preset position at a suitable height from the upper surface of the workpiece. This position must allow space for the striking stroke of the forging cylinder 6, while minimizing idle strokes to improve efficiency.

[0067] S3, Adjust the angle of the side forging unit.

[0068] Based on the workpiece model or the preset forging process specifications, determine which sides or inclined surfaces of the workpiece need to be forged. If side forging is required, control the rotary cylinder 34 to drive the inclined forging table 4 to rotate around the hinge axis via the transmission rod 412 until the axis of the forging cylinder 6 on the inclined forging table 4 or the side forging table 5 is approximately aligned with the normal direction of the workpiece surface to be processed. Once in position, it is locked by the locking component 75.

[0069] S4, laterally fine-tunes the forging position.

[0070] After the angle is adjusted to the correct position, it may be necessary to precisely locate the specific striking point of the forging cylinder 6 on the workpiece contour line. At this time, the transverse drive 81 on the inclined forging table 4 and / or the side forging table 5 is activated respectively, driving the respective transverse plates 83 and the forging cylinder 6 mounted on them to move laterally until the center of the hammer head is aligned with the target forging point on the workpiece. Of course, this process can be controlled by closed-loop feedback through a position sensor.

[0071] S5, fine adjustment of the attack angle. For complex curved surface forging, horizontal lateral movement alone may not be sufficient to achieve an ideal fit between the hammer's working surface and the workpiece surface. In this case, by controlling the differential extension and retraction of the two adjusting cylinders 84 behind the mounting plate 84, the pitch angle of the mounting plate 84 and the forging cylinder 6 is finely adjusted, ensuring that the hammer's working surface maintains the largest possible contact area with the workpiece surface at the moment of contact. This avoids localized stress concentration, improves the forging flow line, and enhances the forming quality.

[0072] S6, execute the forging operation. After all position and angle parameters are set, the forging program starts. The control system controls one or more forging cylinders 6 on the upper forging table 3, the inclined forging table 4, and the side forging table 5 to perform the striking operation according to the set sequence, force, number of times, and rhythm. Under the rotational cooperation of the forging table 2, the workpiece can be forged from multiple directions in sequence. For example, the upper surface can be upset or leveled first, then rotated at a certain angle, and the side forging table 5 can be used for elongation or rolling, and then rotated again and the inclined forging table 4 can be used for the forming of the transition area. Throughout the process, the position and angle of each forging unit can be dynamically adjusted in real time according to the process requirements to achieve near-net-shape forming or local strengthening of complex parts.

[0073] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
