Description

Technical Field

[0001] The invention belongs to the technical field of metal plastic processing and forming, and particularly relates to a device and method for integrally forging and forming high-performance complex components. Background Art

[0002] High-rib and thin-web components are key main structural components widely used in the fields of mechanical engineering, aerospace, transportation equipment, etc. They usually need to work under harsh working conditions such as ultra-high temperature and overweight load. Therefore, higher requirements are imposed on their comprehensive properties such as mechanical properties and fracture properties. In addition, in order to meet the need of weight reduction, such components are usually designed with thin webs and structures such as longitudinal and transverse internal ribs and grounding ribs, which brings great difficulties to the processing of the components. The traditional forming method of high-rib and thin-web components mainly relies on machining after casting. However, defects such as slag inclusion, segregation, shrinkage cavity and porosity are likely to occur during the casting process, resulting in the quality of the produced components not meeting the expected effect; during the machining process, the internal streamline of the rib plate is cut, and the anti-fatigue and anti-corrosion capabilities of the component are reduced, making it difficult to meet the requirements of long life and high reliability of key components.

[0003] In addition, the grounding rib of the high-rib and thin-web component is in the shape of a curved convex platform, the induced tooth is in the shape of high-rib and thin-web, and the symmetric part of the double pin holes has thin walls and deep holes. The complex processing shape and high-precision processing requirements pose very high requirements on the streamline distribution of the formed part. A reasonable streamline distribution in metal parts can effectively improve their performance. A higher streamline continuity plays an important role in improving the bearing capacity, impact toughness, fatigue performance, etc. of the key parts of the component. If there are obvious defects in the metal streamline of the component, such as cross-flow, turbulence, and flow break, the mechanical properties of the formed part will also decrease accordingly. Therefore, ensuring the streamline continuity during the forming process plays a very important role in reducing the weight of the component and increasing the design limit.

[0004] Therefore, in order to avoid the defects generated during the casting process and improve the mechanical properties, surface quality and anti-fatigue performance of the component, it is necessary to propose a device and method for integrally forging and forming high-performance complex components. Summary of the Invention

[0005] The purpose of the invention is to provide a device and method for integrally forging and forming high-performance complex components, so as to solve various defects generated during the casting and forming process of high-performance complex components in the prior art, and further improve the mechanical properties, surface quality and anti-fatigue performance of the components.

The punch and the die are cooperated up and down. At least one pair of side surfaces of the die are provided with opposite extrusion channels. The forming main die slides oppositely at both ends of the extrusion channel. The forming main die penetrates into the extrusion channel and jointly encloses a die cavity with the punch and the die.

The limiting groove and the main die limiting block are in limiting cooperation.

[0012] Preferably, the punch is fixedly connected below a punch connecting plate. Guide pillars and guide sleeves are fixedly connected to the main die positioning plates at the bottoms of both sides of the punch connecting plate. Both sides of the punch connecting plate slide on the two guide pillars and guide sleeves.

[0013] The above structure aims to propose a high-performance integral forging forming device for complex components assisted by ultrasonic vibration. Ultrasonic vibration assistance can significantly reduce the deformation resistance of metals during the forming process, reduce or avoid defects such as cracks, fissures, and scratches in the components during the forming process; reduce the contact friction coefficient between the blank and the die, improve the filling property of the metal, and make the forming profile of the workpiece more precise; the coupling of ultrasonic vibration and pressure can reduce the grain size, refine the microstructure of the metal fiber microcrystals, and reduce the surface roughness of the formed workpiece. Therefore, introducing ultrasonic vibration assistance during the integral forging process can effectively improve the quality of the formed parts.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Refer to Figure 1 As shown, the present invention provides a high-performance complex component integral forging forming device, including a box structure, a forming structure, and an ultrasonic vibration assisting device; wherein, the box structure includes a box body 1 and a main die positioning plate 4, the box body 1 is fixedly connected to the upper surface of the main die positioning plate 4, and the box body 1 serves as a die for the forming of the blank 13, including a female die 11 and a male die 12. At least one pair of side surfaces of the female die 11 are provided with opposite extrusion channels, and a forming main die 5 slides oppositely at both ends of the extrusion channel. The forming main die 5 penetrates into the extrusion channel and jointly encloses a die cavity with the male die 12 and the female die 11; an ultrasonic vibration assisting device is installed above each of the two forming main dies 5, and the ultrasonic vibration assisting device has a side perforated die 10 that enters the female die 11.

[0036] In the above structure, the box structure is the base of the high-performance complex component integral forging forming device, providing protection and support functions, and the integral forging forming of the complex component is completed in the box structure. The forming structure is the main forming die for the high-performance complex component integral forging forming, and complex components such as grounding ribs, induction teeth, and pin ear holes are formed through this structure. The ultrasonic vibration assisting device is an auxiliary device for the forming and demoulding of the pin ear hole, mainly used to reduce the bonding force between the formed part and the die, and improve the demoulding ability and metal filling ability.

[0037] Specifically, in the above embodiment, the box structure includes a box body 1, a main die limiting block 2, a track 3, a main die positioning plate 4, and a guide pillar and guide sleeve 17; as Figure 2As shown in the figure, the box body 1 is fixedly installed above the center of the main die positioning plate 4 by bolts. On the upper surface of the main die positioning plate 4 on both sides of the box body 1, there are tracks 3, and the tracks 3 are perpendicular to the box body 1. At one end of the track 3 close to the box body 1, there is a main die limiting block 2 fixedly connected to the main die positioning plate 4, and the main die limiting block 2 is fixedly installed on the main die positioning plate 4 by bolts. The forming main die 5 slides left and right on the two tracks 3, and the bottom of the forming main die 5 has a limiting groove for the main die limiting block 2 to enter. The length direction of the limiting groove is the same as the direction of the track 3. When the forming main die 5 slides on the track 3, the limiting groove and the main die limiting block 2 form a limiting fit, so that the forming main die 5 can only slide reciprocally within the length range of the limiting groove. On the side wall of the box body 1 facing the two forming main dies 5, there is a side opening for the forming main die 5 to enter. When the two forming main dies 5 slide close to each other on the track 3 at the same time, the blank placed in the box body 1 is extruded.

[0038] In the above embodiment, the forming structure includes a forming main die 5, a main die side connecting plate 18, a side punching die 10, a female die 11, a male die 12, a male die connecting plate 14, a male die positioning flange 15, and a male die connecting rod 16. Among them, as Figure 2 shown, the male die 12 is located on the upper side of the die, the female die 11 is located on the lower side of the die, and the side punching dies 10 are symmetrically distributed on the left and right sides of the female die 11 respectively. The forming main dies 5 are also symmetrically distributed on the left and right sides of the die. The internal structure surrounded by the female die 11, the male die 12, the side punching die 10, the forming main die 5, and the main die side connecting plate 18 forms a die cavity. The die cavity can realize the integral forging forming of complex components with high filling and high streamline continuity through one upsetting forging. The female die 11 and the male die 12 form a matching relationship to achieve the purpose of forming the upper rib plate of the part with high streamline continuity. The female die 11 and the side punching die 10 form a matching relationship to achieve the purpose of forming the left and right side pin ear holes of the part. The male die 12, the female die 11, the forming main die 5, and the main die side connecting plate 18 form a matching relationship to achieve the purpose of forming the tooth-shaped structure with high streamline continuity.

[0039] In the above embodiment, the forming main die 5, the male die 12, and the side punching die 10 are respectively connected to a driving mechanism to generate acting forces in different directions, and multi-directional loading can be realized. Specifically, different driving mechanisms are respectively connected to the main die side connecting plate 18 and the male die connecting rod 16, and the driving mechanism provides the power required for forming.

[0040] As Figure 5 shown, during the actual operation process, the male die connecting rod 16 extrudes the blank downward along the direction indicated by F1, and the forming main die 5 and the ultrasonic vibration assisting device extrude the blank horizontally along the direction indicated by F2 to cooperate to complete the integral forging forming.

[0041] In the above embodiments, since the forming main die 5, the punch 12 and the side punching die 10 are respectively connected to different driving mechanisms, the effect of asynchronous loading can be achieved. Specifically, synchronous loading of the rib plate, pin ear holes and tooth-shaped structure can be realized; synchronous loading of the rib plate and pin ear holes first, and then asynchronous loading of the tooth-shaped structure; and various process schemes such as separate asynchronous loading of the rib plate, pin ear holes and tooth-shaped structure can be realized, and the forging forming scheme can be fully improved according to the process target requirements.

[0042] In the above embodiments, as Figure 1 and Figure 3 shown, both sides of the punch connecting plate 14 slide on two guide pillar bushings 17, and the guide pillar bushings 17 are vertically fixed on the main die positioning plate 4. The punch connecting plate 14, the punch positioning flange 15 and the guide pillar bushings 17 jointly ensure the centering of the punch 12 and the die 11.

[0043] In the above embodiments, the ultrasonic vibration assisting device includes an ultrasonic generator 6, an ultrasonic transducer 7, an ultrasonic horn 8, an ultrasonic protective shell 9 and an ultrasonic chuck 19; the ultrasonic generator 6, the ultrasonic transducer 7 and the ultrasonic horn 8 are arranged inside the ultrasonic protective shell 9. One side of the ultrasonic protective shell 9 away from the die 11 is connected to a driving mechanism. The ultrasonic horn 8 penetrates through the side of the ultrasonic protective shell 9 facing the die 11 and is connected to the side punching die 10 at the protruding end. The ultrasonic chuck 19 is connected to the ultrasonic protective shell 9 and is used for demolding and resetting of the ultrasonic vibration assisting device and the side punching die 10.

[0044] The ultrasonic vibration assisting device can greatly reduce the deformation resistance of the metal during the forming process, reduce or avoid defects such as cracks, fissures and scratches in the component during the forming process; reduce the contact friction coefficient between the blank 13 and the die, improve the filling property of the metal, and make the forming profile of the workpiece more precise; the coupling of ultrasonic vibration and pressure can reduce the grain size, refine the microstructure of the metal fiber microcrystals, and reduce the surface roughness of the formed part. Therefore, introducing ultrasonic vibration assistance during the overall forging process can effectively improve the quality of the formed parts.

[0045] When the ultrasonic vibration assisting device is started, the ultrasonic transducer 7 converts the electrical signal into mechanical vibration and transmits it to the ultrasonic horn 8. The ultrasonic horn 8 transmits the amplified ultrasonic vibration to the side punching die 10, and the side punching die 10 then transmits the vibration to the blank 13, so that the resonating side punching die 10 transmits the ultrasonic vibration to the blank 13. By adjusting the amplitude, frequency and vibration mode of the ultrasonic vibration, it is applicable to the forming of pin ear holes under different conditions; when the side punching die 10 punches and demolds, the ultrasonic vibration assisting device is turned on, which can reduce the bonding force between the formed part and the die and improve the demolding ability and metal filling ability.

[0046] In some embodiments, the ultrasonic transducer 7 is a sandwich transducer, including a metal electrode sheet and a piezoelectric ceramic sheet, and the metal electrode sheet is connected to the ultrasonic generator 6 via a wire.

[0047] In the above embodiment, the integrated forging and asynchronous loading integrated forming method is adopted to effectively reduce the processing procedures and avoid defects generated in the casting process as much as possible; the ultrasonic vibration auxiliary technology is combined with the multi-directional upsetting forming technology, and the blank 13 is plastically deformed through the upsetting process of three independent synchronous or asynchronous loading actions. By reasonably designing the shape of the blank 13 and appropriately selecting the forming parameters, the streamline continuity and filling integrity of the metal are maintained during the integrated forming process of the complex component, so as to obtain a formed component with strong mechanical properties, high surface quality and strong fatigue resistance.

[0048] It should be understood that, in practical applications, the driving mechanism may also be any driving structure or mechanical device capable of realizing linear motion function / rotational motion / telescopic motion, for example, it may be a servo motor, a hydraulic cylinder, an electric cylinder, and the like.

[0049] The present invention provides a method for integrally forging a high-performance complex component, using the above-mentioned device for integrally forging a high-performance complex component, the method comprising the following steps:

[0050] Step 1: Cut the bar material and make it into billet through heat treatment.

[0051] Step 2: Preform the blank by free forging to obtain the blank.

[0052] Step 3: Heat the blank to the target temperature, preheat the mold to a temperature close to the target temperature, specifically ±10°C from the target temperature, and keep it warm for 20 minutes; place the blank into the mold cavity and keep it warm together with the mold at the target temperature for 5 minutes.

[0053] In some embodiments, the blank is heated to a target temperature of 400°C, and the mold is preheated to 390°C to 410°C.

[0054] Step 4: Turn on the ultrasonic vibration auxiliary device and set the ultrasonic vibration amplitude, frequency and vibration mode.

[0055] Step 5: Forging.

[0056] In some embodiments, during forging, the forging body and rib plate are formed by vertical upsetting with a punch, the pin ear holes are formed by upsetting with ultrasonic vibration assistance using perforating dies on both sides, and the tooth structure is formed by upsetting with two forming main dies to complete the forging.

[0057] Step 6: Connect the ultrasonic claw to the driving mechanism, complete the demoulding and resetting of the side perforation mold, and turn off the ultrasonic vibration auxiliary device.

[0058] Step 7: Post-forming treatment to obtain high-performance complex components.

[0059] In some embodiments, the post-forming treatment includes deburring and flash removal.

[0060] After the blank undergoes the forming process proposed by the method of the present invention, plastic deformation occurs, and the metal filling degree and streamline continuity at the key parts of the interior and fillet transitions are high. Processing defects generated during the casting process are avoided as much as possible, realizing the integral forming of complex components and improving the mechanical properties, surface quality, and fatigue resistance of the components.

[0061] It should be noted that the integral forging forming device and method for high-performance complex components of the present invention are not limited to forming the typical complex structural parts mentioned in the present invention. By changing the die structure, it can be extended to form streamline continuous complex structural parts of various structural forms: multi-pin ear hole streamline continuous complex structural parts, double-tooth-shaped structure streamline continuous complex structural parts, etc.; by changing the die structure, it can be extended to form streamline continuous complex structural parts of various size specifications: streamline continuous complex structural parts with large and small height-to-thickness ratios of the tooth-shaped structure, streamline continuous complex structural parts with large and small width-to-diameter ratios of the pin ear holes.

[0062] The embodiments of the present invention disclose the following beneficial effects:

[0063] 1. For the integral forging forming method for high-performance complex components proposed by the present invention, the metal blank is formed by one-time upset forging. The rib plates, pin ear holes, and tooth-shaped structures are integrally forged, avoiding defects generated during the casting process as much as possible. The metal filling degree and streamline continuity are high, and the process is simple and easy to operate. A large amount of plastic strain accumulates inside the material during the upset forging process, which is beneficial to improving the internal tissue properties of the metal, refining the grains, and enhancing the mechanical properties, surface quality, and fatigue resistance of the forgings.

[0064] 2. In the forming device, the punch, side piercing die, and main die can achieve the effect of asynchronous loading, and various process schemes can be realized, such as rib plate - pin ear hole - tooth-shaped structure (synchronous) loading; first rib plate - pin ear hole (synchronous) and then tooth-shaped structure (asynchronous) loading; rib plate, pin ear hole, and tooth-shaped structure are respectively (asynchronous) loaded, etc., fully improving the streamline continuity and filling quality of the forgings according to the requirements of the process objectives.

[0065] 3. Ultrasonic vibration assistance is introduced during the forming process of the pin ear holes, effectively reducing the forming load, improving the metal filling property, and solving the problem of difficult demoulding in traditional die forging processes, providing feasibility for the batch production of high-performance complex components.
