TECHNICAL FIELD
[0001] The present application relates to the technical field of metal processing, in particular to a die steel forging equipment and a forging method thereof. BACKGROUND
[0002] In the field of high-end equipment manufacturing, the quality of large die steel forgings directly determines the service life and reliability of precision dies. With the development of industrial equipment towards large-scale, the demand for die steel forgings with cross-sectional size exceeding 500 mm is increasing, which poses unprecedented challenges to the forging process. The traditional forging mode widely adopted by the current industry has systematic defects, which seriously restricts product quality and production efficiency.
[0003] The mainstream equipment relies on the operation mode of single bearing groove cooperating with the hoisting of the overhead crane. Whenever the processing of a forging surface is completed, the forging process must be interrupted, and the heavy steel billet is transferred to a new station by hoisting equipment and manually adjusting the pose. This operation mode not only causes the forging equipment to be idle during the waiting process, but also exposes the high-temperature steel billet to the air during hoisting, causing the surface temperature to drop sharply. The sharp fluctuation of the temperature field hinders the recrystallization process of the material, and finally forms coarse grain structure in the forging, which becomes a hidden danger of early failure of the product.
[0004] The more difficult problem is the processing limitation of the shaped billet. For die steel billets with irregular cross sections such as multi-prism, the traditional hoisting and overturning can easily cause edge and corner damage and deformation of the steel billet. The operator has to repeatedly adjust the clamping scheme, and try to cover all the surfaces to be forged through multiple heating and hoisting cycles, which not only greatly prolongs the production cycle, but also thickens the oxidation layer on the surface of the steel due to repeated heating. The oxide skin is pressed into the forging body during subsequent forging, forming surface pits and subcutaneous cracks that are difficult to repair.
[0005] To solve the above problems, the on-site operator often needs to intervene in the slag removal and positioning process, but manual intervention brings new quality risks. The deviation of positioning accuracy leads to uneven distribution of forging allowance, which not only increases the burden of subsequent machining, but also may induce forging cracks due to local stress concentration. This vicious cycle makes the production of large die steel forgings fall into the double dilemma of "quality-efficiency", and the industry urgently needs an innovative technical solution that can simultaneously solve the problems of equipment idling, temperature out of control, processing limitation of shaped billets, and manual dependence. SUMMARY
[0006] (I) The technical problem to be solved by the present application is that the existing large die steel forging equipment has high idle rate due to interruption of hoisting, positioning deviation caused by manual adjustment of pose, grain coarsening caused by steel billet temperature drop, and difficult elimination of forging dead angles on the surface of shaped billets, resulting in low forging efficiency and high product defect rate.
[0007] (II) Technical solution To solve the above technical problems, the present application provides a die steel forging equipment, mainly used for the forging of multi-prism die steel blanks, comprising: a bearing table; a bearing member, including a first bearing member and a second bearing member, the first bearing member and the second bearing member are respectively arranged on both sides of the bearing table, each bearing member is provided with a positioning bearing groove with an open top and a through opening penetrating through both ends of the positioning bearing groove, and the inner wall profile of the through opening matches the outer periphery of the steel blank; a pressing mechanism, the pressing end is provided with a forging pressure part corresponding to the top opening of the positioning bearing groove; a turnover mechanism, which drives the first bearing member and / or the second bearing member to rotate, so that the through openings of the first bearing member and the second bearing member are coaxially connected to form a continuous channel for the steel blank, and when the connection is completed, the top opening of the positioning bearing groove of the first bearing member is oriented at an angle greater than 0° with the top opening of the positioning bearing groove of the second bearing member; a pushing mechanism, including a pushing member, the output end of the pushing member is used to push the steel blank from the first bearing member through the continuous channel into the second bearing member, so that the non-exposed surface of the part of the steel blank originally located in the positioning bearing groove of the first bearing member becomes the top exposed surface in the second bearing member.
[0008] According to an embodiment of the present application, the pushing member includes a push block arranged at the output end, and a scraping assembly arranged at the edge of the push block; When the through openings of the first bearing member and the second bearing member are connected, a transfer gap is formed between the connecting end faces of the two bearing members; When the push block pushes the steel blank to move, the scraping assembly scrapes the precipitates on the inner wall of the positioning bearing groove, so that the precipitates fall through the transfer gap and are separated from the positioning bearing groove.
[0009] By arranging the push block at the output end of the pushing member and the scraping assembly at the edge of the push block, the precipitates on the inner wall of the positioning bearing groove are scraped off synchronously during the transfer of the steel blank; the transfer gap formed by the connecting end faces of the two bearing members allows the scraped precipitates to fall immediately, realizing self-cleaning of the bearing groove and preventing secondary forging pollution. This design seamlessly integrates the cleaning process into the transfer process, eliminating the time loss of traditional shutdown cleaning, and avoiding the positioning deviation caused by manual intervention.
[0010] According to an embodiment of the present application, the pushing mechanism further comprises an axial vibrator rigidly connected to the input end of the push block; by rigidly connecting the axial vibrator to the input end of the push block, axial mechanical vibration is generated when the steel blank is pushed, which is transmitted to the scraping assembly to enhance the stripping effect, and at the same time promotes the falling of loose precipitates on the surface of the steel blank.
[0011] When the push block pushes the billet, the axial vibrator generates mechanical vibration parallel to the pushing direction of the billet, avoids interfering with the billet transfer trajectory, and realizes the synergistic improvement of cleaning efficiency and transfer accuracy.
[0012] According to one embodiment of the present application, the billet monitoring device further comprises: A monitoring frame is rigidly connected to the bearing table, surrounds the transfer gap between the first bearing member and the second bearing member, the central through-hole axis is coincident with the continuous channel axis, and the through-hole diameter is greater than the maximum diameter of the continuous channel; A multi-parameter sensing array is uniformly distributed along the circumference of the monitoring frame and is fixed to the inner wall of the frame, including an infrared temperature sensor and an ultrasonic density probe, the infrared temperature sensor is directed to the surface of the exposed section of the billet, and the emission direction of the ultrasonic density probe is perpendicular to the axis of the exposed section of the billet; A state analysis module is signal-connected to the multi-parameter sensing array, receives real-time data of the multi-parameter sensing array and calculates the temperature uniformity index and the core density of the billet; A pressing adjustment module is signal-connected to the state analysis module and the pressing mechanism, and dynamically adjusts the forging parameters of the pressing mechanism of the next station according to the temperature uniformity index and the core density of the billet.
[0013] By arranging the monitoring frame across the billet transfer path, the multi-parameter sensing array synchronously completes the surface temperature field scanning and core density detection of the billet section naturally exposed during the transfer process; the state analysis module calculates the quality index in real time and outputs it to the pressing adjustment module, so that the forging parameter optimization is completed when the billet reaches the second bearing member. The quality monitoring and process adjustment are deeply embedded in the transfer process, realizing zero additional time consumption for forging optimization.
[0014] According to one embodiment of the present application, the billet inlet end of the annular monitoring frame is provided with a circumferential scraper; When the billet passes through the monitoring frame, the circumferential scraper is in contact with the surface of the billet and scrapes off the precipitates adsorbed thereon, so that the precipitates fall through the transfer gap and are separated from the billet.
[0015] By arranging the circumferential scraper at the billet inlet end of the monitoring frame, the precipitates such as scale adsorbed on the surface of the billet are automatically scraped off when the billet enters the monitoring area, and the scraped impurities are immediately discharged through the transfer gap. This design synchronously completes surface cleaning during the billet transfer process, so that the subsequent infrared temperature measurement and ultrasonic density detection are not interfered with by pollution, ensuring the authenticity and reliability of the quality monitoring data.
[0016] According to one embodiment of the present application, the die steel forging equipment further comprises a precipitate receiving device, which is arranged on the bearing table and located at a collection station directly below the transfer gap; The precipitate receiving device comprises a receiving member comprising a top-opened collection cavity for receiving the precipitate falling from the transfer gap.
[0017] By arranging the top-opened receiving member collection cavity directly below the transfer gap, the precipitate stripped by the scraping assembly and the circumferential scraper is received to form a gravity self-flowing collection channel. This design enables all impurities falling from the transfer gap to directly flow into the centralized storage area, eliminating the accumulation of the load table and environmental pollution caused by the scattering of the oxide skin, and providing a complete sample source for subsequent component detection.
[0018] According to one embodiment of the present application, the die steel forging equipment further comprises a precipitate detection device fixed to the load table and located on one side of the transfer gap, comprising: a detection station provided with a component analyzer; a feedback control module signal-connected to the component analyzer and the pressing adjustment module; a sliding guide rail arranged between the collection station and the detection station for guiding and transferring the receiving member, so that the receiving member slides along the sliding guide rail between the collection station and the detection station; when the receiving member moves to the detection station along the sliding guide rail, the component analyzer detects the component of the precipitate and outputs data to the feedback control module, the feedback control module triggers parameter adjustment of the pressing adjustment module according to the precipitate component data.
[0019] By arranging the detection station on the side of the transfer gap, the receiving member can be moved from the collection station to the detection station along the sliding guide rail. When the receiving member is in place, the component analyzer rapidly detects the precipitate in the collection cavity, and the feedback control module triggers parameter optimization of the pressing adjustment module in real time according to the detection data. This design first realizes closed-loop control of the forging process based on the component of the precipitate: the loss rate of alloying elements is back-calculated based on the component of the precipitate in the first forging, and the temperature / pressure parameters are dynamically adjusted in subsequent forging, so that the alloying components retained in the billet body accurately reach the target threshold.
[0020] According to one embodiment of the present application, the load carrier further comprises a third load carrier, the second load carrier and the third load carrier are arranged side by side along a first horizontal direction, and the first load carrier is offset arranged along a second horizontal direction perpendicular to the first horizontal direction, so that the centers of the first load carrier, the second load carrier and the third load carrier in plan view are distributed in an isosceles triangle shape; The turnover mechanism comprises: a driving tilting unit embedded in a bidirectional push rod group of the load table and acting on both sides of the bottom of the first load carrier; a driven tilting unit embedded in a single-sided push rod group of the load table and acting on the outer sides of the second and third load carriers, respectively. The pivot coupling unit comprises an arc-shaped support part arranged at the bottom of each bearing part and a bearing seat arranged on the bearing platform and matched with the arc-shaped support part; When the bidirectional push rod group jacks up the first side of the first bearing part, The first bearing part is pivoted to the second bearing part with the second side arc-shaped support part as the axis, The driven tilting unit drives the second bearing part to tilt to the first bearing part, The through openings of the two bearing parts are butted, When the bidirectional push rod group jacks up the second side of the first bearing part, The first bearing part is pivoted to the third bearing part with the first side arc-shaped support part as the axis, The driven tilting unit drives the third bearing part to tilt to the first bearing part, The through openings of the two bearing parts are butted.
[0021] Through the arrangement of the three bearing parts in the shape of a "pin" and the pivot coupling design of the arc-shaped support part and the bearing seat, a unilateral jacking-contralateral supporting lever structure is formed during the overturning: when the push rod group jacks up one side of the bearing part, the contralateral arc-shaped support part naturally slides along the bearing seat to form a fulcrum, so that the bearing platform continuously bears the main load, and the overturning energy consumption is greatly reduced. This mechanical optimization makes the tilting operation of heavy steel billets convenient and reliable, and completely solves the pain points of the traditional overturning mechanism which is heavy and inefficient.
[0022] For three-prism steel billet forging, although the three sides are adjacent to each other, the traditional lifting needs to be clamped three times independently to cover the whole surface. The scheme realizes efficient forging cycle in the two tilting links through the cooperative transfer path of the three bearing parts: the steel billet first completes the first side forging in the second bearing part, is transferred to the first bearing part to process the second side, and finally is transferred to the third bearing part to complete the third side forging. The whole process does not need to be interrupted during lifting, each bearing part specializes in processing a specific surface, and the forging precision of the three sides is consistent and there is no dead angle omission.
[0023] The present application also provides a die steel forging method, which uses the die steel forging equipment of any one of the above-mentioned embodiments to perform the following steps: S1: placing the steel billet in the positioning bearing groove of the first bearing part, so that the first surface of the steel billet is exposed as the top surface; S2: starting the pressing mechanism to press the top exposed surface by the forging part; S3: driving the overturning mechanism to rotate the first bearing part and / or the second bearing part until the through openings of the two bearing parts are coaxially butted to form a continuous channel; S4: starting the jacking mechanism to push the steel billet from the first bearing part to the second bearing part through the continuous channel, so that the second surface originally located in the first bearing groove becomes the top exposed surface; S5: In the second carrier, the new top exposed surface is forged by the pressing mechanism.
[0024] By placing the steel billet in the first carrier positioning carrier groove, the first side is completed as the exposed surface for the first round of forging; the carrier is rotated to the through opening coaxial docking to form a continuous channel by driving the turnover mechanism; the steel billet is accurately pushed into the second carrier by starting the pushing mechanism, so that the second side in the original carrier groove is automatically converted into the exposed surface to perform the second forging. Through the continuous operation chain of forging-transferring-re-forging, the method completely eliminates the defects of equipment idling and temperature drop caused by hoisting interruption, and realizes efficient and high-quality manufacturing of large die steel forgings.
[0025] The application further provides a die steel forging method, which uses the die steel forging equipment with three carriers to perform the following steps: S1: Place the three-prism steel billet in the second carrier to perform the first round of forging with the first side as the exposed surface; S2: Transport the steel billet to the first carrier, and simultaneously perform the following during the transportation process: a. The annular monitoring frame monitors the steel billet temperature field and density field in real time; b. The state analysis module calculates the steel billet temperature uniformity index and core density; c. The scraping assembly removes the precipitates in the carrier groove; d. The circumferential scraper removes the precipitates on the surface of the steel billet; e. The receiver collects the precipitates and moves them to the detection station; f. The component analyzer detects the composition and quality of the precipitates; S3: In the first carrier, perform forging with the second side as the exposed surface, and dynamically adjust the forging intensity and pressure holding times of this time according to the temperature uniformity index, core density, and composition and quality values of the precipitates obtained in S2; S4: Transport the steel billet to the third carrier, and repeat the a-f detection of S2 during the transportation process; S5: In the third carrier, perform forging with the third side as the exposed surface, and dynamically adjust the forging intensity and pressure holding times of this time according to the detection data of S4.
[0026] Through the directional division of labor of the three carriers and the embedded detection during the transportation process, high-precision forging of the three-prism steel billet is realized: first, the first side is forged in the second carrier; during the transportation to the first carrier, temperature field monitoring, precipitate removal, and component analysis are simultaneously performed; the second side forging parameters are dynamically optimized in the first carrier based on real-time data; finally, the third side is finished in the third carrier. This method deeply integrates quality detection and process adjustment into the transportation process, optimizes the forging parameters of each side independently, and eliminates the compromise of traditional processes.
[0027] (Three) the beneficial effects of the present application: through the cooperative overturning design of the first bearing and the second bearing, a continuous channel through the billet is formed between the forging stations, so that the billet transfer process does not need to be interrupted, and the idle time of the equipment is shortened; based on the profile matching of the positioning bearing groove and the through opening, the self-positioning accurate transfer of the billet between the bearing grooves is realized, and the pose deviation caused by manual adjustment is completely eliminated; by using the angle change of the opening direction of the bearing groove after overturning, the original non-exposed surface of the billet is automatically converted into a forgeable surface, which synchronously covers the full surface of the cuboid and the dead angle area of the special-shaped billet; combined with the continuous pushing mechanism of the pushing mechanism, the temperature fluctuation range of the billet is reduced, and the grain coarsening defect is inhibited from the root. Finally, a seamless cooperative system of forging, transfer and re-forging is constructed, and the forging quality and efficiency of large die steel are improved. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0031] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments. In the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Embodiment 1 As Figure 1 and Figure 10As shown, this embodiment provides a die steel forging equipment, which is mainly used for forging die steel. The steel billet to be forged is a polygonal steel billet. Figure 16 Taking the forging of the rectangular steel billet 101 shown as an example, the die steel forging equipment includes a support platform 1, a support member, a pressing mechanism 3, a turning mechanism 4, a pushing mechanism 5, a billet monitoring device 6, and a precipitate collection and detection system. These components are interconnected and coordinated through a precise mechanical structure and control system. The core goal of their joint operation is to accurately expose the adjacent to-be-processed surfaces of the rectangular steel billet 101 in sequence for forging without relying on traditional lifting interruptions. This continuous, automated operation method is designed to significantly improve the internal microstructure uniformity and mechanical properties of the final die steel product, while greatly improving the efficiency of the overall forging operation.
[0032] like Figures 1 to 4 and Figure 6 As shown, the supporting platform 1 constitutes the main supporting structure of the equipment. It is rectangular in shape and is a rigid frame welded with high-temperature resistant alloy steel plates. In order to cope with the thermal radiation of the high-temperature steel billet during the forging process, the surface of the table is covered with a composite refractory lining, which is composed of a composite of thermal shock-resistant ceramic material and a metal matrix. The table is processed with two troughs 12 along the length direction that are adapted to the shape of the bottom of the supporting part. The two troughs 12 correspond to each other along the length direction of the table. A heating element 121 is provided at the bottom of the trough 12 for heat preservation and heating during the forging process. An array of high-strength heat-resistant alloy anchor bolts are arranged at the bottom of the trough 12, which pass through the table and are firmly connected to the foundation. This design enables the trough 12 to effectively restrain the horizontal displacement of the supporting part in a high-temperature environment, and decomposes and transmits the forging impact force to the foundation through the trough 12 structure, ensuring that the supporting part maintains structural stability during the repeated forging of the red-hot steel billet.
[0033] like Figures 1 to 4 、 Figure 8 and Figure 9As shown, the carrier includes a first carrier 21 and a second carrier 22, which are cast from high-temperature-resistant alloy and are firmly embedded in the fitting groove 12 on both sides of the carrier platform 1 in the length direction. The main structure of each carrier is provided with a positioning carrier groove 210 with a top opening 201. The groove 12 is designed in a U-shaped cross-section that precisely matches the profile of the lower half of the steel blank to be forged. When the steel blank is embedded, its top surface is completely exposed in the top opening 201 area. The through opening 202 penetrating through both ends of the positioning carrier groove 210 has an inner wall profile that strictly copies the geometric shape of the outer periphery of the steel blank, forming a controllable clearance fit relationship on the axial projection plane of the steel blank. When the steel blank is placed in the positioning carrier groove 210, the inner wall constraint mechanism of the through opening 202 cooperates with the bottom support of the positioning carrier groove 210 to achieve precise positioning and attitude locking of the steel blank in three-dimensional space, ensuring that the steel blank does not shift or twist during the forging process, and effectively constraining the steel blank laterally through the groove wall to actively guide the metal plastic flow direction, thereby limiting the forming profile of the steel blank during the forging process.
[0034] As shown in Figures 1 to 5 , the pressing mechanism 3 is provided with two groups of independently driven forging units, which are suspended above the first carrier 21 and the second carrier 22, respectively. The pressing end of each group of forging units is configured with a forging piece 31 that precisely matches the top opening 201 of the positioning carrier groove 210 of the corresponding carrier. When the carrier is in the horizontal forging station, the forging piece 31 can descend along the vertical axis, and its bottom forming surface completely covers the exposed top surface area of the steel blank. The forging piece 31 body is made of a high-temperature-resistant alloy forging base with a multi-layer gradient hard coating on the surface, and the profile edge is provided with a profiled guide chamfer to ensure that the opening side wall of the positioning carrier groove 210 forms a millimeter-level gap fit during the descending process. This design allows the forging pressure to act uniformly on the entire exposed surface of the steel blank, while automatically correcting the slight positional deviation through the profiled guide structure to achieve high-precision closed-die forging at high temperature.
[0035] As shown in Figure 3 , Figure 4 and Figure 6As shown, the flipping mechanism 4 is used to drive the first carrier 21 and / or the second carrier 22 to rotate, so that the through openings 202 of the two carriers are coaxially docked to form a continuous channel for the steel billet, and ensure that the top openings 201 of the positioning bearing grooves 210 of the two carriers after docking are oriented to form a specific angle. There are many ways to implement it. For example, an arc-shaped support portion 220 can be integrated at the bottom of the carrier, and an arc-shaped support seat 13 is set at the corresponding position of the carrier platform 1. The driving unit adopts a high-torque servo motor directly connected to a worm gear reducer, and the output shaft is rigidly connected to the fan gear at the bottom of the carrier. When the motor receives a rotation command, the worm gear pair converts the rotational motion into a precise angular displacement of the fan gear, driving the carrier to tilt along the trajectory of the arc-shaped support seat 13. The key control element is a high-precision angle encoder, which feeds back the tilting angle to the PLC control system in real time. When the encoder detects a 90° rotation of the first carrier 21 (or a 90° rotation of the second carrier 22), the system triggers the locating pin to insert into the locking hole of the arc-shaped support portion 220, ensuring that the through-openings 202 of the two carriers are precisely coaxial. At this point, the top opening 201 of the first carrier 21 faces upward, and the top opening 201 of the second carrier 22 faces forward, forming a 90° spatial angle. This method only requires rotating one carrier to transfer the billet, but there is a risk that the billet will be scratched by the top opening 201 during the transfer process of the rectangular billet 101. The specific implementation method of this embodiment is optimized as follows: like Figure 6 As shown, the two sets of troughs 12 of the support platform 1 are arranged parallel to each other along the length of the platform, but are offset laterally by a specific distance. The inner edges of the two troughs 12 are machined with coaxial arcuate seats 13, with a radius of curvature calculated to match the tilting trajectory of the support components. The inner sides of the bottoms of the first and second support components 21 and 22 are equipped with arcuate support portions 220 that precisely align with the seats 13, forming a linear contact sliding pair with the seats 13. Multiple sets of insertion and rotation slots 230 are distributed along the outer sides of the bottoms along the length, and the inner walls of the slots are quenched and hardened.
[0036] The push actuator unit comprises a single-sided push rod assembly 42, positioned along the length of the load element and partially embedded within the load platform 1. The end of the push rod is connected to a spherical rotating head via a universal joint. The spherical rotating head forms a revolving joint with the load element's insertion slot 230. The push rod passes through a hole in the thermal insulation bushing of the load platform 1 to act on the load element.
[0037] During tilting operation, the control system drives the push rod group 42 on one side, following the lever principle of unilateral force application and fixed fulcrum: The first bearing member 21 is extended by an outer hydraulic push rod, directly acting on the bottom insertion groove 230. At this time, the inner arc-shaped support portion 220 presses the bearing seat 13 of the bearing platform 1 to form a sliding support. Under the thrust of the push rod, the bearing member tilts inward precisely 45 degrees around the fulcrum.
[0038] Second carrier 22: by the outside hydraulic push rod extension, acting on its bottom plug slot 230. Inside the arc-shaped support 220 as a fixed fulcrum, the carrier around the fulcrum to the inside tilt 45 °.
[0039] When the two carriers are tilted 45 °, the through opening 202 is precisely coaxial docking to form a continuous channel for billets. At this time, the first carrier 21 positioning load groove 210 top opening 201 towards the second carrier 22 slot towards the space angle is 90 °, respectively with the adjacent two side of the cuboid billet 101 vertical correspondence.
[0040] As Figure 10 The pusher 501 is used to push the billet from the first carrier 21 through the continuous channel into the second carrier 22, so that the non-exposed surface of the billet originally located in the first carrier 21 positioning load groove 210 is converted into the top exposed surface in the second carrier 22. The pusher 501 adopts box type welded structure, the front end is provided with pressure bearing surface matched with the end surface of the billet, and a plurality of scraping assemblies 502 are circumferentially fixedly connected to the edge of the pusher 501. The scraping assembly 502 is composed of tungsten carbide scraper pre-tightened by spring, and the scraper blade edge protrudes 5-8 mm from the edge of the pusher 501, and forms interference fit with the inner wall of the positioning load groove 210.
[0041] When the first carrier 21 and the second carrier 22 are docked by the turnover mechanism 4, the transfer gap 11 is formed between the docking end surfaces of the two carriers. During the movement of the pusher 501 pushing the billet, the tungsten carbide scraper of the scraping assembly 502 scrapes off the inclusions such as scale adhered to the groove wall in a mechanical cutting manner, and the scraped waste slips backward under the pushing inertia of the billet and freely falls through the transfer gap 11.
[0042] The pusher mechanism 5 also includes an axial vibrator 503, and the shell of the vibrator is rigidly connected with the input end of the pusher 501 through a flange. The vibrator adopts eccentric wheel mechanical excitation principle, and generates linear vibration strictly parallel to the pushing direction when the pusher 501 pushes the billet. The vibration is transmitted to the scraper to enhance the stripping effect, and at the same time, the fine adhering particles are shaken off.
[0043] The inclusions receiving device is arranged on the bearing table 1 below the transfer gap 11, and includes receiving members 71 moving through slide rails. The receiving members 71 are provided with two open top surface collecting cavities 711, and the openings of the two collecting cavities 711 cover the outer edges of the extension plates 203 arranged at the through openings 202 of the transfer output of the two carriers, respectively. The bottom of the collecting cavity 711 is paved with replaceable ceramic lining plate, and the position of the ceramic lining plate is positioned by a photoelectric sensor, so that the inclusions falling through the transfer gap 11 can be completely dropped into the cavity.
[0044] As Figure 7As shown, the core of the billet monitoring device 6 is an annular monitoring frame 61, which is rigidly connected to the middle position of the transfer gap 11 of the supporting platform 1 by high-strength bolts. The axis of the central through hole of the frame is strictly aligned with the central axis of the continuous channel of the billet, and the diameter of the through hole is 15% larger than the maximum diameter of the channel to ensure that there is no contact when the billet passes freely. A multi-parameter sensor array 62 is evenly installed along the circumference of the inner wall of the frame, which includes infrared temperature sensors and ultrasonic density probes arranged alternately. The infrared temperature sensor points to the surface of the exposed section of the billet at an inclination angle of 15°, and calculates the surface temperature distribution by receiving the thermal radiation energy of the billet; the ultrasonic density probe transmitter is installed perpendicular to the axis of the billet, and measures the propagation speed and attenuation of the sound wave inside the billet by emitting high-frequency sound waves and receiving penetration signals.
[0045] As a billet passes through monitoring frame 61, a circumferential scraper 63 at the frame's entrance first contacts the billet's surface. This scraper comprises four sets of spring-loaded tungsten carbide blades, staggered 90° around the billet's circumference. Under constant contact pressure maintained by a pneumatic cylinder, the scraper removes scale and other deposits from the billet's surface. The scraped material falls directly to the transfer gap 11 below under gravity, ensuring the billet's surface cleanliness and creating ideal conditions for subsequent precise inspection.
[0046] Monitoring data is transmitted in real time to the status analysis module, which calculates key quality indicators. Based on the 128-point temperature data collected by the infrared sensor array, the module calculates the standard deviation of the axial and circumferential temperatures of the billet to produce a temperature uniformity index (on a scale of 0-1, with closer to 1 indicating uniformity). Simultaneously, the module analyzes the ultrasonic signal's transit time and amplitude attenuation, and, in conjunction with a material sound velocity-density model, calculates the core density percentage. These indicators directly reflect the uniformity and densification of the forged structure and have a decisive impact on the performance of the die steel. Uneven temperatures can lead to insufficient austenite recrystallization, resulting in coarse grains; insufficient core density reduces fatigue strength and shortens die life.
[0047] The press adjustment module dynamically adjusts the forging parameters of the next workstation based on the state analysis results. When the temperature uniformity index falls below a threshold, the forging heating temperature is automatically increased and the holding time is extended. When the core density is insufficient, the number of forging passes is increased and the strength of each forging pass is enhanced. The specific execution logic is as follows: a pressure sensor controls the hydraulic system flow valve in a closed loop, precisely adjusting the forging force (with an adjustment range of ±15%). A servo motor controls the rotary cam mechanism, varying the forging head's holding time (adjustable from 0 to 10 seconds). A counter relay records the number of forging passes and automatically applies one to three additional presses if the density deviation is significant. This adaptive control, based on real-time quality data, ensures that each billet receives the optimal, customized forging process.
[0048] The precipitate detection device 8 is fixed on the side of the bearing table 1 and keeps parallel distance with the transfer gap 11. Its core is composed of a detection station, double-station sliding guide 72 and feedback control system. The detection station is provided with a laser-induced breakdown spectroscopy (LIBS) component analyzer. The instrument is installed on the upper side of the bearing table 1 through a three-dimensional adjusting support. The pulse laser emission head is directly opposite the center of the collection cavity 711 of the receiving member 71. The focal length adjusting mechanism ensures that the laser beam is focused on the surface of the precipitate pile. The spectral collection optical fiber is directed to the detection point at an angle of 45°. The plasma radiation spectrum is analyzed through a grating spectrometer system.
[0049] The receiving member 71 simultaneously receives the precipitates pushed out by the scraping assembly 502 and the precipitates scraped off by the circumferential scraping plate, so that all the forging objects are collected, and the accuracy of the detection of the precipitate detection device 8 is improved. Specifically, the bottom roller group is arranged on the sliding guide 72. The guide rail is located in the two grooves embedded in the bearing table 1, and is connected between the detection station and the receiving station. The guide rail is matched with a double-V-shaped heat-resistant steel rail and a ceramic ball sliding block. The rail span is accurately matched with the wheel span of the receiving member 71. The two ends of the guide rail are respectively defined as the collection station (directly below the transfer gap 11) and the detection station (below the LIBS analysis point). The middle section is provided with a mechanical positioning slot. When the hydraulic push rod pushes the receiving member 71 to slide along the guide rail, the positioning slot triggers the microswitch at the detection station, so that the receiving member 71 is locked within ±0.2 mm below the LIBS analysis focal point.
[0050] The industrial computer built in the feedback control module realizes process self-adaptive adjustment through three-stage logic. First, component analysis is performed: the laser-induced breakdown spectrometer (LIBS) detects the characteristic spectral line intensity of key alloy elements such as chromium, molybdenum and vanadium in the precipitates. By comparing the reference intensity value of the standard sample, the oxidation loss percentage of each element is calculated. The chromium loss rate and the molybdenum loss rate are used as core control parameters.
[0051] When the chromium loss rate exceeds 12%, the system automatically generates a forging pressure temperature increase instruction. The target temperature is increased by 40 degrees Celsius based on the original set value. When the molybdenum loss rate exceeds 15%, the system generates a forging pressure frequency addition instruction. The forging frequency is increased by three times. If both conditions are met, the system will execute temperature increase and frequency addition simultaneously.
[0052] Finally, the temperature adjustment and the forging cycle increment are transmitted in real time to the programmable logic controller (PLC) of the pressing mechanism 3 through the PROFINET industrial bus network. Upon receiving the instructions, the PLC immediately modifies the forging program for the next station: the temperature control unit automatically adjusts the power output of the induction heater according to the increment value; the forging counter synchronously updates the cycle count setting value. The entire process is completed within 500 milliseconds, ensuring that the process optimization takes effect immediately in the next forging cycle.
[0053] The control system first establishes a quantitative correlation model between precipitate composition and forging parameters. In traditional processes, alloy element loss due to oxidation can only be detected through destructive testing. This solution compensates for element loss in subsequent forging by detecting the chromium and molybdenum loss rate online: the heating operation reduces the thickening of the oxidation layer, and the pressing process promotes the homogenization of the core alloy elements. After verification on the production line, this closed-loop control narrows the surface alloy composition fluctuation range of the die steel from ±1.5% to ±0.5%, significantly improving the service stability of precision molds.
[0054] The control logic converts spectral data into precise process compensation actions through a continuous processing chain of "composition detection - loss calculation - threshold judgment - parameter generation - instruction issuance." The hard-coded loss rate threshold and adjustment amount correspondence ensures optimal energy consumption control while safeguarding material performance, providing core technical support for the composition stability of high-end die steels.
[0055] The continuous forging method of the cuboid die steel forging equipment performs the following steps: S1: Steel billet loading and positioning After preheating, the die steel billet is placed in the positioning bearing groove 210 of the first bearing 21, so that the first face of the steel billet is completely exposed through the top opening 201.
[0056] S2: First face closed die forging The pressing mechanism 3 drives the forging part 31 to descend, and its profile cooperates with the opening of the positioning bearing groove 210 to guide the forging of the exposed first face.
[0057] S3: Bearing turnover and channel construction The turnover mechanism 4 drives the first bearing 21 and the second bearing 22 to rotate cooperatively until the through openings 202 of the two bearings are coaxially connected to form a continuous channel, and the top openings 201 of the two positioning bearing grooves 210 form a 90° spatial included angle.
[0058] S4: Integrated transfer operation The push mechanism 5 is started to push the steel billet from the first bearing 21 into the second bearing 22 through the continuous channel, and the process is performed synchronously: Real-time monitoring of the steel billet body state When the billet passes through the transfer gap 11, the multi-parameter sensing array 62 of the annular monitoring frame 61 scans the exposed section: The infrared temperature sensor acquires the surface temperature field distribution; The ultrasonic density probe measures the core sound speed and attenuation; The state analysis module calculates the temperature uniformity index and the core density.
[0059] Synchronization processing of precipitates The scraping assembly 502 of the pusher 50 scrapes the precipitates on the inner wall of the positioning and bearing groove 210; The circumferential scraper 63 at the entrance of the monitoring frame 61 peels off the oxide layer on the surface of the billet; The detached objects fall through the transfer gap 11 to the collection cavity 711 of the receiving member 71.
[0060] Fast feedback of precipitates The receiving member 71 moves to the detection station along the sliding guide rail 72; The composition analyzer detects the chromium / molybdenum element loss rate of the precipitates in the collection cavity 711; The feedback control module generates optimization instructions for the subsequent billet.
[0061] S5: Second station adaptive forging When the billet enters the second bearing member 22, its originally located second surface becomes the exposed top surface. The pressing mechanism 3 performs dynamic forging based on the dual-source data of S4: Adjust in real time according to the billet body monitoring data: Temperature uniformity index < 0.85 → Increase the forging temperature by 30°C this time; Core density < 90% → Add 2 forging cycles; Chromium loss rate > 12% → Preheat temperature increased by 40°C; Molybdenum loss rate > 15% → Increase the number of reference forging by 3 times.
[0062] The forging method provided by the embodiment synchronously performs body state monitoring and precipitate composition feedback in the steel billet transfer process, and builds a double closed-loop adaptive control system: the monitoring framework 61 integrated at the transfer gap 11 scans the steel billet temperature field and the core density in real time, drives the dynamic compensation of the second station forging pressure parameters, effectively inhibits the grain coarsening and density defects caused by temperature drop, and synchronously collects the precipitates to obtain the alloy element loss rate through rapid spectrum analysis, feeds back the optimized subsequent batch process preset value, and realizes accurate composition control. The method deeply embeds the traditional independent detection and cleaning process into the transfer process, eliminates the temperature drop and efficiency loss caused by hoisting interruption, improves the grain size uniformity of large die steel forgings to ASTM 6 level or above, narrows the alloy composition fluctuation to ±0.5%, reduces the scrap rate by more than 90%, and improves the equipment utilization rate by 300%.
[0063] Embodiment 2 As shown in Figures 11 to 15 , the scheme of the embodiment is basically the same as that of embodiment 1, and the difference lies in that the embodiment is forged into a triangular prism steel billet as shown in Figure 17 , the cross section of the steel billet is an isosceles triangle, and the number of the load bearing members and the shape of the groove body 12 of the positioning bearing groove 210 are correspondingly adapted.
[0064] Specifically, the load bearing member is additionally provided with a third load bearing member 23 on the basis of the original first load bearing member 21 and the second load bearing member 22, forming a three-load bearing member cooperative working system. The second load bearing member 22 and the third load bearing member 23 are arranged in parallel along the first horizontal direction, and the center axes of the two are kept at a fixed distance. The first load bearing member 21 is offset by a set distance along the second horizontal direction perpendicular to the first horizontal direction, so that the center points of the top view projection of the three load bearing members form an isosceles triangle spatial distribution, in which the second load bearing member 22 and the third load bearing member 23 are located at the two top vertices of the bottom side of the triangle, and the first load bearing member 21 is located at the top vertex, forming a stable "pin" shaped mechanical layout.
[0065] As shown in Figure 15 , the pressing mechanism 3 only includes one forging member 31, the support mechanism covers each load bearing member, and is provided with a moving mechanism 32 for transferring the forging member 31.
[0066] The overturning mechanism 4 comprises three groups of functional units working in coordination: the active tilting unit adopts a bidirectional push rod group 41 embedded in the carrier table 1, the rod body is provided with an arc consistent with the movement track of the pushing position, and the two groups of output ends are respectively applied to the thrust joint parts on the two sides of the bottom of the first carrier 21; the driven tilting unit is composed of two groups of unilateral push rod groups 42 embedded in the carrier table 1, and is respectively applied to the outer bottom of the second carrier 22 and the outer bottom of the third carrier 23; the pivotal coupling unit is provided with an arc-shaped support part 220 at the bottom of each carrier, and the carrier table 1 is fixedly installed with a precisely matched bearing seat 13 at the corresponding position, so as to form a rotating pair with low friction coefficient.
[0067] When the bidirectional push rod group 41 lifts the first side of the first carrier 21: the first carrier 21 tilts to the second carrier 22 side with the second side arc-shaped support part 220 as the shaft, and the second side arc-shaped support part 220 slides along the surface of the bearing seat 13 to form a transient rotating fulcrum; simultaneously, the driven tilting unit drives the second carrier 22 to tilt to the first carrier 21 side, so that the two carriers realize coaxial butt joint of the through opening 202 at a set inclination angle. When the reverse operation is performed, the bidirectional push rod group 41 lifts the second side of the first carrier 21: the first carrier 21 tilts to the third carrier 23 side with the first side arc-shaped support part 220 as the shaft, and the driven tilting unit synchronously drives the third carrier 23 to tilt to the first carrier 21 side to complete the butt joint. The pivotal coupling design forms a lever structure with unilateral lifting and opposite side support, and the carrier table 1 continuously bears the main tilting load through the bearing seat 13, so that the energy consumption of the overturning operation of the heavy steel billet is significantly reduced.
[0068] Based on the cooperation of the isosceles triangle layout and the tilting mechanism, an efficient forging path of the three-prism steel billet 102 is constructed: the steel billet first completes the first side forging on the second carrier 22, then is transferred to the first carrier 21 to process the second side, and finally is transferred to the third carrier 23 to complete the third side finish forging. The three carriers cover specific forging surfaces based on spatial position division, realize full-surface no-dead-angle processing in the two tilting links, do not need to be interrupted during hoisting and transporting in the whole process, and ensure the consistency of the forging precision of the sides of the three-prism.
[0069] The forging method of the three-prism die steel forging equipment executes the following steps: S1: first round reference surface forging The three-prism steel billet 102 preheated to 1150±10°C is placed in the positioning bearing groove 210 of the second carrier 22, so that the first side of the steel billet is completely exposed through the top opening 201. The closing mechanism 3 is started to execute closed die forging, a reference forging force of 1200 tons is applied, and three times of pressure maintaining operation is executed, with 8 seconds for each time. In this stage, the temperature fluctuation of the initial forging temperature is monitored in real time through the temperature measuring hole preinstalled in the groove bottom, so as to ensure that the temperature stability is controlled within a range of ±15°C.
[0070] S2: cooperative transfer and embedded detection After the first round of forging, the overturning mechanism 4 is started to make the second carrier 22 coaxially butt joint with the through opening 202 of the first carrier 21 to form a continuous channel, and the billet is transferred from the second carrier 22 to the first carrier 21 through the pushing mechanism 5. Six key operations are performed synchronously during the transfer process: When the billet passes through the transfer gap 11, the multi-parameter sensing array 62 of the annular monitoring frame 61 scans the surface temperature field distribution and the core acoustic characteristics of the exposed section of the billet in real time; The state analysis module calculates the axial / circumferential temperature uniformity index (target value ≥ 0.9) and the core density (target value ≥ 92%) based on the scanning data; The scraping assembly 502 at the edge of the pushing block 501 of the pushing piece 50 removes the oxide precipitates adhered to the inner wall of the positioning bearing groove 210 of the second carrier 22; The circumferential scraper 63 at the entrance of the monitoring frame 61 scrapes the precipitated layer adsorbed on the corners of the billet at a constant contact pressure; The receiving piece 71 collects all the precipitates falling through the transfer gap 11 and moves them to the detection station along the sliding guide rail 72; The laser-induced breakdown spectrometer detects the loss rate of Cr, Mo and the impurity content in the precipitates.
[0071] S3: Dynamic optimization of forging on the second side After the billet enters the first carrier 21, the originally non-exposed second side is converted into the top exposed surface. The forging parameters are dynamically adjusted according to the real-time data obtained in S2: If the temperature uniformity index is less than 0.9, the forging temperature is increased by 50°C and one additional forging cycle is added; If the Mo loss rate is greater than 15%, the forging force is increased to 115% of the reference value; If the core density is less than 90%, the single holding time is extended to 12 seconds. The pressure combination mechanism 3 performs adaptive forging according to the optimized parameters, and simultaneously feedbacks the contact stress distribution in real time through the in-groove pressure sensing array.
[0072] S4: Secondary transfer and iterative detection The billet is transferred from the first carrier 21 to the third carrier 23, and the detection operations a-f of S2 are repeated during the transfer process. The composition of the precipitates is compared and analyzed: if the Cr loss rate is detected to increase by more than 2% compared with the previous transfer, the spectrometer calibration program is triggered and the composition analysis model is corrected.
[0073] S5: Closed-loop control of final forging Final forging is performed in the third carrier 23 with the third side as the exposed surface: When the temperature field scanning shows that the edge temperature difference is greater than 100°C, the gradient forging mode is enabled: 1300 tons of pressure is applied to the center area, and the pressure of the edge area is reduced by 10%. According to the difference (ΔD) between the measured value and the target value of the core density, the number of forging is dynamically compensated: 1 additional forging for every 2% deviation (number of forgings = reference number + ΔD / 2); The laser displacement sensor is used to monitor the corner filling degree in real time, and the pressure holding is automatically terminated when the filling degree reaches 99.8%. After the final forging is completed, the surface temperature uniformity of the steel billet is improved to within ±25℃, and the grain size difference of the three sides is controlled within ASTM 0.5 level.
[0074] The method realizes independent process optimization of each side of the triangular prism through closed-loop control of embedded detection and dynamic parameter adjustment in the transportation process. Compared with the traditional process, the occurrence rate of corner cracks is reduced to below 0.05%, the segregation rate of alloy elements is compressed to 0.3%, and the single-piece forging cycle is shortened to 28 minutes.
[0075] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
