[0043] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that discussions of these implementations are merely provided to enable those skilled in the art to better understand so as to be able to implement the subject matter described herein, and variations of elements discussed can be made by one skilled in the art without departing from the scope of the present specification. Various processes or components can be omitted, substituted, or added according to desired implementations. Additionally, features described with respect to some examples can be combined in other examples.

[0044] Referring to Figure 1 and Figure 2 The application discloses a metal processing forging forming machine tool, which comprises a support frame 100, wherein the bottom of the support frame 100 is provided with a forming unit 200.

[0045] Referring to Figure 3The forming unit 200 comprises a forming seat 210 fixed to the bottom of the support frame 100, and a forming cavity 211 is formed in the forming seat 210, and a raised rib plate 212 adapted to the formed part is arranged at the bottom of the forming cavity 211;

[0046] Please refer to Figure 4 、 Figure 5 and Figure 9 , the top material piece 220 is arranged at the bottom of the forming seat 210, the top material piece 220 comprises a movable top plate 221 penetrating the bottom of the forming cavity 211 and a sliding sleeve 222 fixed to the support frame 100, a top rod 223 is slidingly arranged in the sliding sleeve 222, the top of the top rod 223 is fixedly connected with the top plate 221, and a through slot 213 adapted to the top plate 221 is formed in the bottom of the forming cavity 211;

[0047] Specifically, in the initial state, the top plate 221 is just embedded in the through slot 213, and at this time, the upper end surface of the top plate 221 is flush with the bottom surface of the forming cavity 211; when the forging forming is completed, the top rod 223 is pushed upward along the sliding sleeve 222, so as to drive the top plate 221 to eject the formed part in the forming cavity 211, so as to realize the demolding of the formed part.

[0048] It should be noted that the upper end surface of the top plate 221 is flush with the bottom surface of the forming cavity 211 during forging, so as to ensure that there is no interference on the formed surface of the forging; when demolding, the top rod 223 is pushed upward, so that the formed part is stably and uniformly ejected from the cavity by the top plate 221, avoiding the damage to the forging or the die caused by the traditional prying or knocking method, and the method is particularly suitable for precision forgings with complex structures such as the raised rib plate 212;

[0049] The embedded design of the top plate 221 ensures that the forming cavity 211 has complete rigidity and structural integrity during forging, can effectively withstand the great impact force of the forging unit 300, prevents the weakening or deformation of the die strength, and thus guarantees the size precision of the forging.

[0050] Further, please refer to Figure 6 and Figure 7 , the support frame 100 is provided with a feeding unit 400 on one side, the feeding unit 400 comprises a feeding frame 410 and a fixed hopper 420 fixed to the top of the feeding frame 410, a movable hopper 430 linked with the top material piece 220 is horizontally slidingly installed below the fixed hopper 420, and a feeding cylinder 440 for driving the movable hopper 430 is installed on one side of the feeding frame 410;

[0051] Specifically, the fixed hopper 420 is used to store the blank for forging forming, when the feeding cylinder 440 retracts, the movable hopper 430 is driven to slide to the side away from the forming seat 210, at this time the opening above the movable hopper 430 just connects with the opening at the lower end of the fixed hopper 420, so that a blank in the fixed hopper 420 falls into the movable hopper 430, at the same time the linkage ejection part 220 synchronously ejects the formed part in the forming cavity 211; then the feeding cylinder 440 extends, horizontally pushes the movable hopper 430 to move towards the side of the forming seat 210, until the movable hopper 430 just reaches above the forming seat 210, so as to push the ejected formed part to the side, at the same time the blank in the movable hopper 430 just falls into the forming cavity 211, to realize automatic feeding of the blank; after feeding is completed, the feeding cylinder 440 drives the movable hopper 430 to slide and reset again.

[0052] It is worth noting that by driving the movable hopper 430 to reciprocate between the fixed hopper 420 and the forming seat 210 by the feeding cylinder 440, automatic circulation from blank storage, fixed-point receiving to precise feeding is realized, which seamlessly connects the feeding and forging core processes, and shortens the production rhythm;

[0053] The design of the fixed hopper 420 cooperating with the horizontally sliding movable hopper 430 ensures that the moving track of the movable hopper 430 can accurately dock with the lower end opening of the fixed hopper 420 at the feeding position to receive the blank, and eject the formed part; at the feeding position, the movable hopper 430 can be accurately moved above the forming seat 210 to push out the formed part, and at the same time the blank can be accurately dropped into the forming cavity 211, which provides a guarantee for subsequent forging of high-quality products.

[0054] In an embodiment, please refer to Figure 7 , the side of the movable hopper 430 away from the forming seat 210 is provided with an isolation sealing disc 450 matched with the bottom opening of the fixed hopper 420, and the guide rails 460 are horizontally fixed on both sides of the feeding frame 410, and the movable hopper 430 is provided with the rollers 470 matched with the guide rails 460 on both sides;

[0055] Specifically, the height of the movable hopper 430 can only accommodate one blank, when the feeding cylinder 440 extends horizontally, it can push the movable hopper 430 to slide horizontally, and the rollers 470 adaptively roll along the guide rails 460 towards the side of the forming seat 210, when the movable hopper 430 is staggered with the fixed hopper 420, the isolation sealing disc 450 can just block the lower end opening of the fixed hopper 420, so as to avoid the blank at the bottom of the fixed hopper 420 from falling, when the movable hopper 430 slides and resets, the isolation sealing disc 450 is staggered with the lower end opening of the fixed hopper 420, and so on, to realize feeding of the blanks one by one.

[0056] It should be noted that when the movable hopper 430 carries a blank to the forming seat 210, the isolation sealing disc 450 will move synchronously and immediately seal the bottom opening of the fixed hopper 420, ensuring that other blanks in the fixed hopper 420 will never accidentally fall during the movement of the movable hopper 430, so that only one blank is transported each time, avoiding equipment jamming or cavity damage caused by multiple blanks falling at the same time, and ensuring smooth production flow;

[0057] The sliding pair formed by the guide rail 460 and the roller 470 provides stable support for the horizontal movement of the movable hopper 430 with high rigidity and low friction, effectively preventing the movable hopper 430 from shaking, jamming or deviating during movement, and ensuring that it can accurately stop at the receiving and feeding positions each time.

[0058] Further, please refer to Figure 8 , the top of the support frame 100 is movably provided with a forging unit 300 adapted to the forming unit 200, the forging unit 300 includes a guide rod 310 vertically installed on the support frame 100, a lifting seat 320 is slidingly installed on the guide rod 310, a hydraulic cylinder 330 is provided at the top of the support frame 100 for driving the lifting seat 320, and a forging pressing plate 340 adapted to the forming seat 210 is installed at the bottom of the lifting seat 320;

[0059] Specifically, after the blank is placed in the forming cavity 211 of the forming seat 210, the lifting seat 320 is driven by the hydraulic cylinder 330 to slide downward along the guide rod 310, which drives the forging pressing plate 340 to descend until the forging pressing plate 340 enters the forming cavity 211 to press and form the blank.

[0060] Further, please refer to Figure 4 、 Figure 5 and Figure 8 , the lifting seat 320 is symmetrically provided with a lifting frame 350 on both sides, a clamping groove 351 is formed on one side of the lower end of the lifting frame 350, a counterweight seat 224 is fixedly connected to the lower end of the top rod 223, and a pull rod 225 is symmetrically provided on both sides of the counterweight seat 224 and adapted to the corresponding clamping groove 351;

[0061] Specifically, when the lifting seat 320 drives the forging press plate 340 to perform the press forging, the lifting frame 350 is driven to descend synchronously, and when the forging press plate 340 enters the forming cavity 211, the pull rods 225 on both sides of the counterweight seat 224 are just clamped into the corresponding clamping grooves 351 on the lifting frame 350, and then the forging forming is completed. During the upward resetting process of the lifting seat 320 driving the forging press plate 340, the pull rods 225 can be pulled upward synchronously by the lifting frame 350, thereby driving the counterweight seat 224 and the ejector pin 223 to ascend, so as to realize the synchronous ejection demolding of the blank by the top plate 221, and then the lifting frame 350 is separated from the pull rod 225, and the top material piece 220 automatically descends and resets under the gravity of the counterweight seat 224, so that the top plate 221 accurately falls back into the through groove 213, thereby preparing for the next forging;

[0062] It should be noted that after the lifting seat 320 drives the forging press plate 340 to complete the forging forming, the return upward movement can automatically and synchronously eject the formed piece by the clamping of the lifting frame 350 and the pull rod 225. The triggering of the ejection action is accurately limited in the upward stroke after the forging press plate 340 completely separates from the forming cavity 211, so as to realize the synchronization of the resetting process of the forging press plate 340 and the demolding process of the formed piece.

[0063] In addition, referring to Figure 4 and Figure 5 , the upper end of the lifting frame 350 is rotatably installed on the lifting seat 320, the lower end of the lifting frame 350 is provided with a wedge surface 352 matched with the pull rod 225, the movable hopper 430 is fixed with a push rod 490 matched with the lifting frame 350, and the side of the support frame 100 away from the movable hopper 430 is provided with a groove 101 accommodating the lifting frame 350;

[0064] Specifically, when the lifting seat 320 descends, the lifting frame 350 is driven to descend synchronously until the wedge surface 352 at the lower end of the lifting frame 350 abuts against the pull rod 225, and then the lifting frame 350 is forced to gradually turn to one side of the groove 101 due to the limitation of the pull rod 225 in the vertical direction, until the pull rod 225 and the wedge surface 352 slide relative to each other and are clamped into the clamping groove 351, and the lifting frame 350 is turned back to the vertical state again. Then, the lifting seat 320 ascends, and the pull rod 225 can be pulled upward by the lifting frame 350, so as to realize the automatic mold ejection of the top plate 221;

[0065] Then, when the movable hopper 430 slides horizontally to load, the push rods 490 on both sides of the movable hopper 430 can quickly push the lifting frame 350 to turn to one side of the groove 101 and enter the groove 101, so that the pull rod 225 and the clamping groove 351 are instantaneously separated, and the top plate 221 can fall back and reset under the gravity of the counterweight seat 224. After the loading is completed, the movable hopper 430 slides and resets, the push rod 490 is separated from the lifting frame 350, and the lifting frame 350 can be turned to the vertical state again.

[0066] It is worth noting that when forging down, the lifting frame 350 is automatically captured and clamped by the interaction of the wedge surface 352 and the pull rod 225; after ejection is completed, the movable hopper 430 in the feeding process automatically triggers the lifting frame 350 to flip through the push rod 490, realizing release and reset;

[0067] When the lifting seat 320 goes down, the wedge surface 352 can convert the kinetic energy of vertical downward into the force to force the lifting frame 350 to flip laterally, thereby forcibly guiding the pull rod 225 to slide into the clamping groove 351, avoiding the misalignment or clamping failure that may occur in the traditional hooking mechanism, and ensuring that the connection with the ejection part can be reliably completed in each forging stroke;

[0068] Through the push rod 490 fixed on the movable hopper 430, the push to the lifting frame 350 is completed synchronously in the feeding process, so that it is separated from the pull rod 225, ensuring that the ejection reset action and the feeding action are completely synchronized in time, and the backfall reset of the top plate 221 is completed before the billet is fed, clearing the way for smooth feeding and avoiding possible motion interference. This precise timing ensures seamless connection between processes from a mechanical structure, providing reliable protection for maximizing production rhythm.

[0069] Please refer to Figure 1 , Figure 2 and Figure 6 , the supporting frame 100 is provided with a discharging unit 500 away from the feeding unit 400, the discharging unit 500 includes a discharging frame 510 and a roller 520 rotatably installed on the top of the discharging frame 510, the discharging frame 510 is provided with a guide plate 530 near the supporting frame 100, the guide plate 530 is connected to the forming seat 210 and the roller 520, and the movable hopper 430 is provided with a push plate 480 near one end of the forming seat 210;

[0070] Specifically, when the top plate 221 ejects the formed part in the forming cavity 211, the bottom surface of the formed part is at the same height as the top surface of the forming seat 210 and the upper end surface of the guide plate 530. Then, during the feeding process of the horizontal sliding of the movable hopper 430 towards the forming seat 210, the push plate 480 pushes the ejected formed part through the guide plate 530 and into the roller 520 to discharge it. Then, the top plate 221 falls back to its original position, and the billet in the movable hopper 430 falls into the forming cavity 211 to complete the feeding process.

[0071] It is worth noting that the discharging action and the feeding action are integrated into the same horizontal sliding stroke of the movable hopper 430, and when the movable hopper 430 advances with new billets, the push plate 480 at the front end of the movable hopper 430 simultaneously pushes the ejected formed part away from the forming seat 210, so that the feeding and discharging processes are completely parallel in time, eliminating the separate discharging time.

[0072] The chute is constructed by the guide plate 530 between the top surface of the forming seat 210 and the roller 520, and precisely matches the ejection stroke of the top plate 221, ensuring that the ejected workpiece can enter the unloading process without obstruction. The core power of the unloading function is directly reused to drive the feeding cylinder 440 of the movable hopper 430, and the push plate 480 is an accessory of the movable hopper 430, which synchronously completes the action of pushing and unloading when performing the feeding task.

[0073] The top plate 221 remains in a high position after ejecting the workpiece, providing space for the push plate 480 to push the material. After the push plate 480 completes the push, the top plate 221 falls back to the original position, and a new blank falls into the forming cavity 211, avoiding interference between moving parts and the risk of jamming during the transfer process of the workpiece.

[0074] In further embodiments, please refer to Figure 9 and Figure 10 The bottom of the forming seat 210 is embedded with a heating unit 230 adapted to the forming cavity 211. The heating unit 230 includes a first heat exchange channel 231 and a second heat exchange channel 232 distributed in parallel below both sides of the raised rib plate 212. One side of the forming seat 210 is provided with a distribution cavity 236 communicating with the first heat exchange channel 231 and the second heat exchange channel 232. The distribution cavity 236 is eccentrically provided with a rotating drum 237. A plurality of inflation cavities 238 are circumferentially formed in the rotating drum 237. A sealing plate 239 is slidably embedded in the inflation cavity 238 and abuts against the inner wall of the distribution cavity 236.

[0075] Specifically, the blank to be forged is placed in the forming cavity 211, and the blank in the forming cavity 211 can be forged by the downward pressure of the forging unit 300.

[0076] The heating unit 230 can locally preheat the forming cavity 211 before forging and heat the entire forming cavity 211 during forging. Each inflation cavity 238 of the rotating drum 237 is pre-filled with gas. Under the action of the gas pressure in the inflation cavity 238, the sealing plate 239 is always active and extends out and tightly fits the inner wall of the distribution cavity 236, thereby separating the crescent-shaped space formed between the distribution cavity 236 and the rotating drum 237.

[0077] Please refer to Figure 12 Before forging, the rotating drum 237 is rotated to a specific position and remains stationary. At this time, the two groups of sealing plates 239 symmetrically distributed above and below the rotating drum 237 separate the crescent-shaped space, and only the inner part of the first heat exchange channel 231 and the corresponding second heat exchange channel 232 remain open. Figure 8The middle dotted arrow represents the heating liquid flow path, and the flow path between the outer first heat exchange flow channel 231 and the corresponding second heat exchange flow channel 232 is cut off, so that the heating liquid flowing in the inner first heat exchange flow channel 231 and the second heat exchange flow channel 232 is used to locally preheat the area of the raised rib plate 212 in the forming cavity 211, avoiding the occurrence of rib cracking in the corresponding area of the blank after forging;

[0078] Please refer to Figure 13 In the forging forming, the rotating drum 237 continuously rotates clockwise, so that the dynamic sealing space formed by the sealing plate 239 and the distribution cavity 236 continuously sucks the heating liquid in each first heat exchange flow channel 231, and then press into the corresponding second heat exchange flow channel 232, accelerate the flow rate of the heating liquid, improve the overall heating effect of the forming cavity 211, effectively prevent the surface cracks of the blank in the forging forming.

[0079] It should be noted that through the dynamic cooperation of the eccentric rotating drum 237 and the sealing plate 239 in the heating unit 230, the rotating drum 237 can be controlled to be stationary at a specific position before forging, and the sealing plate 239 thereon cuts off the outer flow channel, only the inner first heat exchange flow channel 231 and the second heat exchange flow channel 232 are conducted, so as to locally preheat the area of the raised rib plate 212 in the forming cavity 211, avoid the occurrence of rib cracking in this area due to large temperature difference after forging; During the forging process, the rotating drum 237 continuously rotates, and the sealing plate 239 thereon forms a dynamic pumping effect, forcibly accelerates the circulating flow rate of the heating liquid in all first heat exchange flow channels 231 and second heat exchange flow channels 232, and strengthens the overall uniform heating of the forming cavity 211, effectively preventing the generation of surface cracks of the blank;

[0080] By combining local preheating with overall intensive heating, the blank can always maintain an ideal plastic state during the forging process, not only effectively inhibiting crack defects, but also effectively improving the metal filling performance and uniformity of the metal, especially suitable for forming metal forgings with complex structures such as recessed rib cavities;

[0081] During the overall heating process, the rotating drum 237 and the sealing plate 239 can continuously suck and pressurize the heating liquid flowing through the distribution cavity 236, effectively improving the flow rate in the first heat exchange flow channel 231 and the second heat exchange flow channel 232, and strengthening heat transfer, so as to realize rapid and uniform heating of the formed blank during the forging process.

[0082] Further, please refer to Figure 9 and Figure 11The heating unit 230 further comprises a liquid inlet cavity 233 and a liquid return cavity 234 arranged in the forming seat 210, the liquid inlet cavity 233 is in communication with one end of the first heat exchange channel 231 away from the distribution cavity 236, and the liquid return cavity 234 is in communication with one end of the second heat exchange channel 232 away from the distribution cavity 236;

[0083] Specifically, the external heating liquid is introduced into the liquid inlet cavity 233, then the heating liquid enters the distribution cavity 236 through each first heat exchange channel 231, and then the heating liquid flows into the liquid return cavity 234 through the second heat exchange channel 232, and finally is discharged from the liquid return cavity 234.

[0084] It should be noted that the liquid inlet cavity 233 can uniformly distribute the externally introduced heating liquid to the inlet end of each first heat exchange channel 231, effectively avoiding the flow deviation phenomenon of each channel caused by the difference in flow path resistance, ensuring the uniform flow of heating liquid to the complex structure area such as the raised rib plate 212, thereby providing a more uniform and stable initial thermal field for the forming cavity 211, and improving the uniformity of preheating effect from the source.

[0085] By arranging the liquid return cavity 234 in communication with the second heat exchange channel 232, in cooperation with the liquid inlet cavity 233, a closed circulation passage is formed inside the forming seat 210, reducing the loss of heat energy in the transmission process, so that the heat carried by the heating liquid can be more concentrated and efficiently transmitted to the forming seat 210 and the blank, thereby improving the heat utilization efficiency of the entire heating unit 230.

[0086] Further, referring to Figure 11 The bottom of the forming cavity 211 is further provided with a plurality of heat exchange plates 235, and the heat exchange plates 235 are staggered distributed with the first heat exchange channel 231 and the second heat exchange channel 232.

[0087] Specifically, each heat exchange plate 235 is arranged between adjacent first heat exchange channels 231 and second heat exchange channels 232, and the heating liquid can quickly and uniformly transfer heat to the adjacent heat exchange plate 235 when flowing through the first heat exchange channel 231 and the second heat exchange channel 232. Then the heat is quickly introduced into the forming cavity 211 through the heat exchange plate 235 to realize the preheating of the forming cavity 211, especially the raised rib plate 212 area, and the subsequent full-area heating in the forging forming.

[0088] It is worth noting that by arranging a plurality of heat exchange plates 235 between the first heat exchange channel 231 and the second heat exchange channel 232, the original linear heat transfer limited to the channel wall is expanded to surface heat transfer through the entire plate, thereby constructing an efficient heat equalizing framework inside the forming seat 210, which can quickly and uniformly laterally conduct the heat carried by the heating liquid in the channel to the entire area at the bottom of the forming cavity 211, effectively eliminating local temperature difference and ensuring the extreme uniformity of preheating and heating effect.

[0089] The heat exchange plates 235 are vertically embedded into the bottom of the forming cavity 211, and their layout is staggered with the flow channels, forming a three-dimensional heat conduction matrix, which is conducive to efficiently directing and concentrating heat to the raised rib plate 212, which is a critical and easily cracked area. The heat is transferred to the heat exchange plates 235 through the flow channels, and then directly and rapidly acts on the blank through the heat bridge of the heat exchange plates 235, achieving precise and rapid heat supply for complex structures, and fundamentally preventing the occurrence of rib cracks;

[0090] A large number of heat exchange plates 235 themselves have significant heat capacity, and they are heated synchronously with the flow channels during the heating process, together forming a stable high-temperature heat reservoir. When the forging unit 300 presses the blank, the heat storage of the heat exchange plates 235 effectively compensates for the heat loss caused by contact conduction, maintains the stability of the blank temperature, and better adapts to the demand for instantaneous high heat load in the forging process;

[0091] The heat exchange plates 235 ensure that heat energy does not have to rely entirely on the slow longitudinal conduction of the steel body, ensuring that heat can cover the entire bottom of the forming cavity 211 without dead angles, thereby achieving global balanced heating of the blank in forging, effectively reducing the probability of surface cracks.

The above specific embodiments are only illustrative and not limiting. Those skilled in the art can make many forms under the inspiration of the present application, which are all within the protection scope of the present application.
