Description

Technical Field

[0001] This invention relates to the field of titanium alloy forming technology, specifically to a superplastic forming device and process for ultra-large irregularly shaped titanium alloy parts. Background Technology

[0002] Titanium alloys refer to various alloys made of titanium and other metals. Titanium is an important structural metal developed in the 1950s. Titanium alloys have high strength, good corrosion resistance, and high heat resistance. In the 1950s and 1960s, the main focus was on developing high-temperature titanium alloys for aero engines and structural titanium alloys for airframes.

[0003] Patent publication number CN117564178B discloses a superplastic forming device and process for ultra-large irregularly shaped titanium alloy parts. This invention relates to the field of titanium alloy forming technology and solves the problem of needing to change different specifications of feeding mechanisms to feed sheet metal when processing irregularly shaped titanium alloy parts. The device includes a base, on which a frame is fixedly connected. A first hydraulic telescopic rod is fixedly connected to the frame, and an upper mold is fixedly connected to the bottom end of the first hydraulic telescopic rod. A lower mold located below the upper mold is fixedly connected to the base. A control box is located above the base, and a horizontal position adjustment structure is fixedly connected to the base. The horizontal position adjustment structure drives the control box to move horizontally. The control box is a hollow structure with an open bottom. A support plate is located inside the control box, and the support plate and the top inner wall of the control box are connected by several first connecting columns. Several support frames are located below the support plate. This facilitates the feeding and processing of irregularly shaped sheet metal, improving its applicability and convenience.

[0004] While the above methods facilitate the loading and processing of irregularly shaped sheets, the following shortcomings remain: Currently, in superplastic molding production lines, the three main processes—sheet handling, mold cleaning, and release agent spraying—are typically completed by independent equipment. These processes operate sequentially and are strongly coupled, requiring each process to be fully completed before the next can start, resulting in lengthy production cycles and cumbersome operating procedures. Furthermore, the dispersed layout of multiple machines not only occupies a large area but also increases the complexity of system integration and collaborative control, hindering the improvement of overall production efficiency and automation levels. Summary of the Invention

[0005] The purpose of this invention is to provide a superplastic forming device and process for ultra-large irregular titanium alloy parts, which aims to solve the problem that the three major processes of plate handling, mold cleaning and release agent spraying are usually completed by independent equipment in the prior art, which makes the operation process cumbersome and occupies a large area.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: the superplastic forming device and process for ultra-large irregular titanium alloy parts includes a moving mechanism installed on the ground, a moving plate fixed at the bottom of the moving mechanism, and a multi-functional mechanism installed at the bottom of the moving plate.

[0021] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1 A superplastic forming device for ultra-large irregular titanium alloy parts includes a moving mechanism 1 installed on the ground, a moving plate 2 fixed to the bottom of the moving mechanism 1, and a multi-functional mechanism installed at the bottom of the moving plate 2. The multi-functional mechanism can clamp the plate. Then, the moving plate 2 and the multi-functional mechanism move under the action of the moving mechanism 1 to load and unload the plate. No manual operation is required, which improves work efficiency and reduces the labor intensity of workers.

[0023] In this embodiment, the plate is made of an extra-large irregularly shaped titanium alloy part.

[0024] like Figure 1 and Figures 4-6 As shown, the moving mechanism 1 can adjust the position of the multi-functional mechanism when it moves, so as to facilitate the handling of the plate.

[0025] Specifically, the moving mechanism 1 includes a gantry frame 101, a reciprocating track 102, a moving trolley, and a connecting rod 103. The gantry frame 101 slides on the ground. The crossbeam of the gantry frame 101 has a hollow structure inside. In this embodiment, the structure and principle of the gantry frame 101 are existing technologies and will not be described in detail here. The lower end of the gantry frame 1 is fixed with a moving wheel, which is not shown in the figure. The reciprocating track 102 is fixed on the inner wall of the hollow structure. The bottom of the gantry frame 101 has a guide hole that communicates with the hollow structure and allows the connecting rod 103 to slide. The moving trolley is inserted into the reciprocating track 102. The bottom of the moving trolley is fixedly connected to the connecting rod 103. The bottom of the connecting rod 103 is fixedly connected to the top of the moving plate 2, so that when the moving trolley moves along the reciprocating track 102, it can drive the moving plate 2 to move along the reciprocating track 102 through the connecting rod 103, thereby realizing the reciprocating movement of the multi-functional mechanism.

[0026] In this embodiment, the connecting rod 103 is an electric telescopic rod or a hydraulic telescopic rod. The structure and principle of the electric telescopic rod or the hydraulic telescopic rod are existing technologies and will not be described in detail here. When it is necessary to load or unload materials, the height of the moving plate 2 can be adjusted by the connecting rod 103.

[0027] The mobile trolley includes a frame 8, wheels 9, a first motor 10, gears 11, and racks 12. There are four wheels 9, rotatably mounted on both sides of the frame 8, rolling within a reciprocating track 102. The first motor 10 is mounted inside the frame 8. There are two gears 11; the output shaft of the first motor 10 is connected to a shaft via a first bevel gear set. Both ends of the shaft are fixedly connected to the two gears 11. In this embodiment, the first bevel gear set includes a first main bevel gear and a first auxiliary bevel gear. The first main bevel gear is connected to the first motor... The output shaft of motor 10 is fixedly connected. The first set of bevel gears is fixed with an axle. The two ends of the axle are fixedly connected to gear 11. When the first motor 10 is started, it can drive gear 11 to rotate. There are two racks 12, which are fixed on the inner bottom wall of the reciprocating track 102 respectively. When the first motor 10 is started, the frame 8 can move along the extension direction of the reciprocating track 102 because the gears 11 and racks 12 mesh with each other. This allows the wheels 9 to move along the extension direction of the reciprocating track 102. The bottom of the frame 8 is fixedly connected to the connecting rod 103.

[0028] In this embodiment, distance sensors are provided on both the front and rear sides of the frame 8. The distance sensors and the first motor 10 are both connected to the controller signal so that the distance sensors can monitor the distance between the frame 8 and the gantry frame 101 and avoid the frame 8 from hitting the side wall of the gantry frame 101. The structure and principle of the distance sensor are existing technologies and will not be described in detail here.

[0029] like Figures 4-6 As shown, the multi-functional mechanism includes a handling component 3, which is installed at the bottom of the movable plate 2 so that the handling component 3 can handle the plate.

[0030] In this embodiment, an internal ejector rod (not shown in the figure) is designed inside the lower mold. After molding, the ejector rod is driven by hydraulic or pneumatic means to lift the workpiece smoothly and evenly from the lower mold surface from below. After being lifted, the workpiece is separated from the lower mold, and the space above and to the side is released. Then, the conveying component 3 will carry away the workpiece that has been separated from the lower mold. The structure and principle of the ejector rod in the lower mold are existing technologies and will not be described in detail here.

[0031] Specifically, the handling assembly 3 includes two sets of first telescopic devices 301, two fixed plates 302, two guide rails 303, two sets of connecting rod components, and two clamping plates 304. In this embodiment, the first telescopic devices 301 are electric telescopic rods or hydraulic telescopic rods. The structure and principle of electric telescopic rods or hydraulic telescopic rods are existing technologies and will not be described in detail here. Several height-adjustable telescopic rods 13 are fixed below the moving plate 2. In this embodiment, the height-adjustable telescopic rods 13 are electric telescopic rods or hydraulic telescopic rods. The structure and principle of electric telescopic rods or hydraulic telescopic rods are existing technologies and will not be described in detail here. Through the setting of the height-adjustable telescopic rods 13, the height of the fixed plate 302 can be adjusted. The lower end of each height-adjustable telescopic rod 13 is fixedly connected to the upper end of the corresponding fixed plate 302. The first telescopic devices 301 are fixedly installed on the upper end of the fixed plate 302, the guide rails 303 are fixed on the lower end of the fixed plate 302, and the two clamping plates 304 slide on the two guide rails 303. The connecting rod components are installed on the fixed plate 304. At the bottom of plate 302, the connecting rod component is hinged to two clamping plates 304; the movable end of the first telescopic device 301 is fixedly connected to one of the clamping plates 304 through a first connecting plate, so that the first telescopic device 301 can be activated, and the first telescopic device 301 can drive the corresponding clamping plate 304 to move along the extension direction of the guide rail 303. A sleeve rod is fixed to the fixed end of the first telescopic device 301, and the sleeve rod is fixedly connected to another clamping plate 304 through a second connecting plate. The fixed plate 302 has a fork for the second clamping plate 304 to move. The first and second connecting plates are guided by limiting holes for sliding. When one of the clamping plates 304 moves along the extension direction of the guide rail 303, it can drive the other clamping plate 304 to move along the extension direction of the guide rail 303 through the connecting rod member, so that the two clamping plates 304 move in opposite or opposite directions. In this embodiment, the clamping plate 304 is L-shaped and has an inclined surface on the side close to the plate so that the clamping plate 304 can be inserted under the plate during the clamping process so that the two clamping plates 304 can clamp the plate.

[0032] Each linkage component includes two long linkages 14 and one short linkage 15. The short linkage 15 is hinged to the lower end of the fixed plate 302. Both ends of the short linkage 15 are hinged to the long linkages 14 respectively. The ends of the long linkages 14 away from the short linkages 15 are hinged to the corresponding clamping plates 304. When the first telescopic device 301 is activated, it drives the corresponding clamping plate 304 to move. Through the rotation of the two long linkages 14 and the short linkage 15, it drives one end of the other clamping plate 304, so that the two clamping plates 304 can move in opposite or opposite directions.

[0033] In this embodiment, a pressure sensor is provided on the side wall of the clamping plate 304. When the plate is clamped, it will squeeze the pressure sensor to monitor that the plate is clamped in place. The pressure sensor is connected to the controller signal. The structure and principle of the pressure sensor are existing technologies and will not be described in detail here.

[0034] Working principle: By operating the moving mechanism 1, the device is moved above the plate to be transported. The two sets of first telescopic devices 301 of the transport component 3 are activated. Through the linkage mechanism, the two clamping plates 304 are driven to move towards each other along the guide rail 303 to clamp the plate from both sides. After the plate is clamped, the moving mechanism 1 can be activated again, moving the transport component 3 with the plate clamped to a stable transport position and accurately placing it into the mold. This process can improve work efficiency and reduce the labor intensity of workers.

[0035] Example 2 In the structure of Embodiment 1, since the clamping plate 304 is L-shaped and there is no limit on the top of the plate, the plate may tilt and warp, causing the plate to be placed unevenly and easily resulting in damage to the plate during processing.

[0036] Based on the above problems, in this embodiment, as follows: Figures 6-8 As shown, each clamping plate 304 has a chamber 16 inside, and an auxiliary clamping component 17 is provided in the chamber 16. The auxiliary clamping component 17 and the clamping plate 304 can clamp the plate and limit the upper and lower sides of the plate to prevent it from warping.

[0037] Specifically, the auxiliary clamping assembly 17 includes a second motor 1701, a second bevel gear set 1702, a rotating shaft 1703, and a pressing plate 1704. In this embodiment, the second bevel gear set 1702 includes a second main bevel gear and a second auxiliary bevel gear. The second main bevel gear is fixedly connected to the output shaft of the second motor 1701, and the second auxiliary bevel gear is fixedly connected to the rotating shaft 1703. The second motor 1701 is fixed inside the chamber 16. The output shaft of the second motor 1701 is connected to the rotating shaft 1703 via the second bevel gear set 1702. The rotating shaft 1703 rotates inside the chamber 16. There are several pressing plates 1704, which are fixed on the rotating shaft 1703. When the second motor 1701 is started, it can drive the rotating shaft 1703 to rotate via the second bevel gear set 1702. When the rotating shaft 1703 rotates, it can drive the pressing plates 1704 to flip out from inside the chamber 16 and press them onto the plate, thereby pressing the pressing plates 1704 onto the plate.

[0038] In this embodiment, the pressure plate 1704 is an elastic pressure block made of silicone, polyurethane or rubber to avoid damage to the workpiece.

[0039] Compared to Embodiment 1, in this embodiment, the clamping plate 304 can clamp the plate laterally, and the auxiliary clamping component 17 can press on top of the plate. Through the coordinated action of the clamping plate 304 and the auxiliary clamping component 17, the plate can be firmly gripped, and it can be placed in case of slippage or falling during movement, thus improving safety. Example 3 In the structures of Embodiments 1 and 2, before the plates are placed, the mold needs to be cleaned and a release agent sprayed manually. This manual operation is slow and requires a lot of labor.

[0040] Based on the above problems, in this embodiment, as follows: Figure 1 , Figure 2 and Figure 9 As shown, the multifunctional mechanism also includes an auxiliary processing component and a transmission component 4. The transmission component 4 is installed at the bottom of the movable plate 2 and is located behind the transport component 3. The lower part of the transmission component 4 is connected to the auxiliary processing component, enabling the auxiliary processing component to clean and spray the mold, while the transmission component 4 can drive the auxiliary processing component to adjust different functions.

[0041] Specifically, the transmission assembly 4 includes a third motor 401, a rotating plate 402, and an auxiliary support component. The third motor 401 is installed below the moving plate 2, and the lower end of the output shaft of the third motor 401 is fixedly connected to the rotating plate 402. The auxiliary processing component is installed on the rotating plate 402. When the third motor 401 is started, the output shaft of the third motor 401 can drive the rotating plate 402 to rotate. When the rotating plate 402 rotates, it can adjust the different functions of the auxiliary processing component and realize the switching of different functions. In this embodiment, the third motor 401 is intermittently rotating in both forward and reverse directions and will not rotate 360° to avoid the problem of the auxiliary processing component's wiring getting tangled. The auxiliary support component is located between the rotating plate 402 and the moving plate 2 to improve the operational stability of the rotating plate 402.

[0042] The auxiliary support components include several round rods and several limiting wheels. The lower end of the round rod is fixedly connected to the corresponding limiting wheel, and the upper end of the round rod is fixedly connected to the lower end of the moving plate 2. The upper end of the rotating plate 402 is provided with an annular groove. The round rods and limiting wheels are guided and slid in the annular groove, so that when the rotating plate 402 rotates, the suspension force can be distributed on the round rods and limiting wheels, reducing the suspension force of the third motor 401 and extending the service life of the third motor 401.

[0043] like Figure 9As shown, the auxiliary processing components include a high-pressure blowing component 5, an extraction and collection component 6, and a spraying component 7. The high-pressure blowing component 5, the extraction and collection component 6, and the spraying component 7 are all installed below the transmission component 4, so that the high-pressure blowing component 5 can clean the impurities in the mold, and the extraction and collection component 6 can extract and recover the cleaned impurities so that the plate can be placed into the mold. Before the plate is placed into the mold, the release agent can be sprayed onto the mold by the spraying component 7.

[0044] Specifically, the high-pressure air blowing component 5 includes a second telescopic device 501, an air blowing nozzle 502, an air blowing pump 503, and an air box. In this embodiment, the second telescopic device 501 adopts an electric telescopic or hydraulic telescopic rod. The structure and principle of the electric telescopic or hydraulic telescopic rod are existing technologies and will not be described in detail here. The air box is fixed on the movable plate 2, and the second telescopic device 501 is fixed on the rotating plate 402. The movable end of the second telescopic device 501 is fixedly connected to the air blowing nozzle 502. The input end of the air blowing nozzle 502 is fixedly connected to the air blowing pump 503. The air blowing pump 503 is fixedly connected to the air box, which is not shown in the figure. When the air blowing pump 503 is started, it can spray high-pressure gas through the air blowing nozzle 502 so that the air blowing nozzle 502 can clean impurities in the mold. In this embodiment, the high-pressure air blowing component 5 can adopt a dust blowing gun. The structure and principle of the dust blowing gun are existing technologies and will not be described in detail here.

[0045] The suction and collection component 6 includes a third telescopic device 601, an air extraction pipe head 602, an air extraction pump 603, and a collection box. In this embodiment, the third telescopic device 601 is an electric telescopic or hydraulic telescopic rod. The structure and principle of the electric telescopic or hydraulic telescopic rod are existing technologies and will not be described in detail here. The collection box is installed on the movable plate 2, and the third telescopic device 601 is fixed on the rotating plate 402. The movable end of the third telescopic device 601 is fixedly connected to the air extraction pipe head 602, and the input end of the air extraction pipe head 602 is fixedly connected to the air extraction pump 603. The air extraction pump 603 is fixedly connected to the collection box, which is not shown in the figure. When the air extraction pump 603 is started, it can extract the debris through the air extraction pipe head 602. In this embodiment, the suction and collection component 6 can be a vacuum cleaner. The structure and principle of the vacuum cleaner are existing technologies and will not be described in detail here. The cleaned debris can be extracted into the collection box by the action of the air extraction pipe head 602.

[0046] The spraying component 7 includes a fourth telescopic device 701, a liquid spray nozzle 702, a suction pump 703, and a storage tank. In this embodiment, the fourth telescopic device 701 adopts an electric telescopic or hydraulic telescopic rod. The structure and principle of the electric telescopic or hydraulic telescopic rod are existing technologies and will not be described in detail here. The storage tank is installed on the movable plate 2, and the fourth telescopic device 701 is fixed on the rotating plate 402. The movable end of the fourth telescopic device 701 is fixedly connected to the liquid spray nozzle 702, and the input end of the liquid spray nozzle 702 is fixedly connected to the suction pump 703. The suction pump 703 is fixedly connected to the storage tank, which is not shown in the figure. When the suction pump 703 is started, it can spray the release agent onto the mold through the liquid spray nozzle 702. In this embodiment, the suction collection component 6 can adopt a water gun. The structure and principle of the water gun are existing technologies and will not be described in detail here, so that the release agent in the storage tank can be sprayed onto the mold through the liquid spray nozzle 702.
