Description

Technical Field

[0001] The present invention relates to the technical field of metal casting equipment, and particularly to a positioning device for ship metal die forging. Background Art

[0002] In the field of shipbuilding, metal die forging is a crucial processing technology, which plays a decisive role in manufacturing various key components on ships. Ship metal components usually need to have high strength, high precision, and good toughness to adapt to the harsh conditions of the marine environment and the complex working conditions of ship operation. Traditional ship metal die forging processing mainly relies on manual operation to complete the clamping and movement of blanks. In this processing method, workers use simple clamping tools, such as pliers, fixtures, etc., to place the blanks into the forming die for forging.

[0003] Regarding the above related technologies, it is found that there are many disadvantages in manually clamping and moving the blanks. Firstly, the accuracy of manual clamping is difficult to guarantee. Due to the instability of human operation, it is very difficult to ensure the accurate placement of the blank in the die during the processing. Secondly, the safety of manual operation is relatively low. During the die forging process, the high-temperature blank and the strong forging pressure pose a threat to the personal safety of workers.

[0004] In order to improve the accuracy and efficiency of die forging processing, some existing die forging equipment has also begun to introduce some simple mechanical auxiliary devices. However, the functions of these devices are limited, and most of them can only operate at a single angle and position, and cannot be flexibly adjusted according to different working scenarios and die sizes. When processing different blank workpieces, these devices often cannot provide effective positioning and clamping. Summary of the Invention

[0005] The present invention solves the problems in the related technologies and provides a positioning device for ship metal die forging to solve the problems of poor positioning accuracy, low operation safety, and inability to meet the flexible forging of different blanks in the existing metal die forging.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions: A positioning device for ship metal die forging includes a die forging base and a forming die arranged above the die forging base. A mechanical base is arranged on the outer side of the die forging base. A rotating base is rotatably installed on the mechanical base, and a rotating oil cylinder one for driving the rotating base to rotate is fixedly installed at the lower end of the mechanical base. An adjustable machine base is horizontally fixed on the upper end surface of the rotating base. An equipment rotating frame is rotatably installed on the outer end surface of the adjustable machine base, and a rotating oil cylinder two for driving the equipment rotating frame to rotate is also installed on the adjustable machine base. Two groups of multi-functional frames are slidably installed on the front end surface of the equipment rotating frame, and a control component for adjusting the distance between the two groups of multi-functional frames is also arranged on the upper end surface of the equipment rotating frame. A positioning clamp group matched with the forming die is fixedly installed on the multi-functional frame.

[0007] By adopting the above technical solution, the forming die is arranged above the die forging seat to realize the forming processing operation of the blank. At the same time, a mechanical seat is arranged on the outer side of the die forging seat, which is convenient for installing the rotating seat through the mechanical seat. When in use, through the setting of the rotating seat and the first rotating oil cylinder, the adjustable machine base can rotate circumferentially around the mechanical seat, so as to adjust the overall use angle and position of the equipment and adapt to different working scenarios. For example, taking and placing the blank between the blank box and the forming die, and taking and placing the finished product between the forming die and the conveyor belt, which is easy to meet the flexible operation between different positions. At the same time, the adjustable machine base is horizontally fixed on the upper end face of the rotating seat. When in use, the equipment rotating frame can be installed through the adjustable machine base. In this way, during the positioning and clamping use process, it can move horizontally through the adjustable machine base, and at the same time, the second rotating oil cylinder can drive the equipment rotating frame to rotate on the adjustable machine base, further increasing the flexibility of the device, ensuring stable clamping of the blank and flexible angle adjustment during the forming process to meet different use requirements of forging. By sliding and installing two groups of multi-functional frames on the front end face of the equipment rotating frame, it is convenient to install the positioning clamp group through the two groups of multi-functional frames. At the same time, the distance between the two groups of multi-functional frames can be adjusted through the control component, which is convenient to install positioning clamp groups with different sizes and structures through the multi-functional frames. In this way, it is convenient for different positioning clamp groups to match the corresponding forging dies, increasing the applicable range of equipment use. When in use, the positioning clamp group cooperates with the forming die to realize the flexible control of the workpiece processed on the forming die, ensuring the accuracy of the die forging process.

[0008] As a preferred solution, the adjustable machine base includes a machine base plate, a horizontal sliding rod, and a vertical plate seat for the equipment rotating frame to be rotatably installed. The horizontal sliding rod is slidably installed in the machine base plate. The vertical plate seat is fixedly installed at the outer end of the horizontal sliding rod. And a first telescopic oil cylinder connected to the vertical plate seat is installed on the lower end face of the machine base plate. An annular seat for the equipment rotating frame to be rotatably installed is arranged on the outer side face of the vertical plate seat. The annular seat is integrally formed with the vertical plate seat. The second rotating oil cylinder is fixedly installed on the vertical plate seat, and the output end of the second rotating oil cylinder passes through the annular seat and is connected to the equipment rotating frame.

[0009] By adopting the above technical solution, when in use, the horizontal sliding rod in the adjustable machine base can slide in the machine base plate, and the first telescopic oil cylinder can drive the vertical plate seat to move horizontally, so as to adjust the horizontal position of the equipment rotating frame to meet the demand of horizontal position adjustment in use. The setting of the annular seat provides a stable support for the rotation of the equipment rotating frame. The second rotating oil cylinder is connected to the equipment rotating frame through the annular seat, and can accurately control the rotation angle of the equipment rotating frame.

[0010] As a preferred solution, the equipment rotating frame includes a main frame block and a slide rail seat for slidably mounting the multi-functional frame. One end of the main frame block is rotatably mounted on the annular seat, and the slide rail seat is fixedly mounted on the other end of the main frame block. A partition vertical plate is fixedly mounted in the middle of the slide rail seat. Support springs for supporting the multi-functional frame are fixedly mounted on both sides of the partition vertical plate. Outer covers are also mounted at both ends of the slide rail seat. The outer covers are fixedly connected to the slide rail seat, and a conduit seat is integrally formed in the middle of the outer covers.

[0011] By adopting the above technical solution, the equipment rotating frame is designed as a structure in which the main frame block and the slide rail seat cooperate. When in use, the main frame block of the equipment rotating frame is rotatably mounted on the annular seat, ensuring the rotational flexibility of the equipment rotating frame. The slide rail seat provides a track for the sliding of the multi-functional frame. The setting of the partition vertical plate and the support springs, on the one hand, plays a supporting role for the multi-functional frame, ensuring that the multi-functional frame can automatically slide to the outer side when not subject to external forces, and on the other hand, provides buffering when the multi-functional frame slides, reducing the impact of vibration on the equipment. The setting of the outer covers and the conduit seat protects the internal structure of the slide rail seat and at the same time provides a sliding guide for the linkage pressing frame of the control component.

[0012] As a preferred solution, the multi-functional frame includes a movable slider and an outer seat plate. The movable slider is slidably mounted in the slide rail seat. The outer seat plate is arranged on the outer side surface of the movable slider and is integrally formed with the movable slider. A number of connection holes are provided on the outer seat plate.

[0013] By adopting the above technical solution, the movable slider of the multi-functional frame can freely slide in the slide rail seat. The outer seat plate is integrally formed with the movable slider, ensuring the structural stability. The connection holes on the outer seat plate facilitate the installation of the positioning clip group, making it convenient to replace and adjust according to different positioning requirements.

[0014] As a preferred solution, the control component includes a disc seat, a double spiral rotating frame, and two groups of linkage pressing frames that cooperate with the movable slider. The disc seat includes a bottom plate and a central shaft. The bottom plate is fixedly mounted on the upper end surface of the slide rail seat, and the central shaft is vertically fixed at the center of the upper end surface of the bottom plate. The double spiral rotating frame is rotatably mounted on the central shaft, and a telescopic oil cylinder two for adjusting the angle of the double spiral rotating frame is mounted on the main frame block. Two groups of linkage pressing frames are mounted on both sides of the double spiral rotating frame, and the distance between the two groups of linkage pressing frames is adjusted by the rotation of the double spiral rotating frame.

[0015] By adopting the above technical solution, during use, the disk base is used as the positioning and installation mechanism of the double spiral frame. At the same time, by designing the disk base into a structure where the bottom plate and the central shaft cooperate, during use, the disk base is fixedly installed on the slide rail base, so as to ensure that the double spiral frame can be stably sleeved on the central shaft, realizing stable rotational installation. During use, the angle of the double spiral frame can be adjusted by the telescopic oil cylinder two. The double spiral frame adjusts the distance between the two groups of linkage pressure frames by rotation, thereby controlling the distance between the two groups of multi-functional frames, achieving precise adjustment of the distance between the multi-functional frames, and then controlling the clamping width of the positioning clamp group through the multi-functional frames to adapt to blanks and products of different sizes.

[0016] As a preferred solution, the double spiral frame includes a central sleeve, a driving disk and a limiting top disk. The central sleeve is sleeved and installed on the central shaft, and an outer arm rod connected to the telescopic oil cylinder two is fixedly installed on the outer side surface of the central sleeve. Both the driving disk and the limiting top disk are sleeved and fixed on the central sleeve, and two eccentric grooves are opened on the driving disk. The linkage pressure frame includes a right-angle frame, a pressing slide rod and a synchronous connecting rod slidably installed in the eccentric groove. The pressing slide rod is slidably installed in the conduit seat, and one end of the pressing slide rod supports on the movable slider. The other end of the pressing slide rod is fixedly connected to the right-angle frame. The synchronous connecting rod is fixedly installed at the end of the right-angle frame away from the pressing slide rod.

[0017] By adopting the above technical solution, the central sleeve of the double spiral frame is sleeved on the central shaft, ensuring the stable rotation of the double spiral frame. The outer arm rod is connected to the telescopic oil cylinder two, realizing the driving of the double spiral frame by the telescopic oil cylinder two. The eccentric groove on the driving disk cooperates with the synchronous connecting rod of the linkage pressure frame. When the double spiral frame rotates, the rotational motion can be converted into the linear motion of the linkage pressure frame, thereby controlling the sliding of the multi-functional frame, and the limiting top plate is arranged to ensure the upper end of the synchronous connecting rod is limited, ensuring that the synchronous connecting rod can slide stably in the eccentric groove.

[0018] As a preferred solution, the positioning clamp group includes a bent and expanded frame, a positioning table and an insertion plate rod. One end of the bent and expanded frame is fixedly installed on the outer side surface of the outer seat plate. The positioning table is fixedly installed at the other end of the bent and expanded frame. The insertion plate rod is fitted and installed on the inner side surface of the positioning table, and a rotary oil cylinder three for driving the insertion plate rod to flip is also fixedly installed on the outer side surface of the positioning table. A reinforcing bent plate is fixedly installed on the upper end surface of the insertion plate rod. A limiting slider is integrally formed at the head of the reinforcing bent plate, and a limiting arc groove for the limiting slider to slide and install is opened on the inner side surface of the positioning table.

[0019] By adopting the above technical solution, the bending and expanding frame of the positioning clamp group is used to connect the outer seat plate and the positioning table, increasing the working range of the positioning table and facilitating the positioning clamp group to clamp workpieces with larger sizes after being installed on the positioning table. At the same time, the rotary oil cylinder III can drive the insertion plate rod to turn over, facilitating the up and down fine adjustment of the head of the insertion plate rod when clamping the workpiece on the forming die, making it more convenient for the head of the insertion plate rod to insert into both sides of the workpiece for clamping. At the same time, the head of the insertion plate rod adopts an inclined surface structure, which further increases the ability of the insertion plate rod to insert into the gap. The insertion plate rod is slidably connected to the positioning table through the reinforcement bent plate and the limiting arc groove, making it more stable when the rotary oil cylinder III drives the insertion plate rod to turn over and adjust, and improving the stability of the insertion plate rod for clamping the workpiece.

[0020] As a preferred solution, the positioning clamp group includes a positioning seat, a guide shell, a telescopic rod and a jaw head. Clamping plates fixedly connected to the outer seat plate are arranged on both sides of the positioning seat, and the clamping plates are integrally formed with the positioning seat. The guide shell is fixedly installed on the front end face of the positioning seat. The telescopic rod is slidably installed in the guide shell, and an internally threaded tube is fixedly installed in the middle of the telescopic rod. A threaded rod matched with the internally threaded tube is arranged in the guide shell, and a built-in motor for driving the threaded rod to rotate is fixedly installed in the positioning seat. The jaw head is sleeved and fixedly installed at the outer end of the telescopic rod.

[0021] By adopting the above technical solution, when in use, the positioning seat of the positioning clamp group is fixedly connected to the outer seat plate through the clamping plate, and locking bolts can be installed on the lower end face of the clamping plate. After being installed on the outer seat plate, it can be locked by rotating the locking bolts, facilitating quick disassembly and assembly operations. The guide shell provides guidance for the sliding of the telescopic rod. The built-in motor drives the threaded rod to rotate, and drives the telescopic rod to expand and contract through the internally threaded tube, thereby realizing the expansion and contraction movement of the jaw head, and can be precisely adjusted according to the position of the forming die.

[0022] As a preferred solution, the jaw head includes a head seat, a bottom support plate and two groups of double-layer jaws. A sleeve shell connected to the telescopic rod is arranged on the rear end face of the head seat. The bottom support plate is fixedly installed on the lower end face of the head seat. Two rotating shaft rods for installing the double-layer jaws are rotatably installed on the head seat. The two rotating shaft rods are connected by two meshing gear discs. One end of the double-layer jaw is sleeved and fixedly installed on the rotating shaft rod, and an anti-slip clamping block is integrally formed at the other end of the double-layer jaw. A rotary oil cylinder IV for driving the rotating shaft rod to rotate is also fixedly installed on the bottom support plate.

[0023] By adopting the above technical solution, when in use, the head seat of the jaw head is connected to the telescopic rod through the sleeve housing. By rotatably installing the rotating shaft rod on the head seat, it is convenient to install the double-layer jaws through the rotating shaft rod, ensuring that the double-layer jaws can rotate and clamp during use. The two rotating shaft rods are connected through the gear disk, ensuring the synchronous rotation of the two double-layer jaws and facilitating stable rotational opening and closing clamping operations. The setting of the bottom support plate facilitates the stable installation of the rotary oil cylinder four. During use, the rotary oil cylinder four drives the rotating shaft rod to rotate, enabling the double-layer jaws to perform opening and closing actions. The setting of the anti-slip clamp blocks increases the stability of clamping and can firmly clamp the blank.

[0024] As a preferred solution, a positioning groove is formed in the lower end surface of the anti-slip clamp block. A buffer housing is fixedly installed in the positioning groove. One end of the buffer housing is provided with an arc-shaped housing that is communicated therewith, and a liquid inlet pipe that is matched therewith is arranged on the upper end surface of the buffer housing. A plurality of spray heads are evenly installed on the lower end surface of the arc-shaped housing. A temperature-resistant connecting pipe that is communicated with the liquid inlet pipe is fixedly installed between the double-layer jaws. Two box-shaped brackets are symmetrically installed on the upper end surface of the machine base plate. A liquid storage tank is fixedly installed between the two box-shaped brackets. A spray pump is also fixedly installed on the machine base plate. The suction port of the spray pump is connected to the liquid storage tank, and a spiral water supply hose that is communicated with the temperature-resistant connecting pipe is installed at the discharge port of the spray pump.

[0025] By adopting the above technical solution, by forming a positioning groove in the lower end surface of the anti-slip clamp block, it is convenient to stably install the buffer housing through the positioning groove. At the same time, the buffer housing and the arc-shaped housing on the lower end surface of the bottom support plate form a spray system. During use, the spray pump transports the demolding liquid in the liquid storage tank to the spray heads through the spiral water supply hose and the temperature-resistant connecting pipe, and sprays the forming die before die forging, which plays a role in improving the demolding effect and improves the die forging quality and operability.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: By arranging structures such as a mechanical base, an adjustable base, an equipment rotating frame, a multi-functional frame, a control component, and a positioning clamp group outside the forming die in this application, it is convenient to perform positioning clamping and auxiliary movement on the blank through the coordinated work of multiple adjustable components during use. Compared with the traditional manual clamping method for the blank, it can not only effectively improve the precision positioning, but also significantly increase the safety of processing. During actual operation, the setting of the rotating seat, the first rotary oil cylinder, and the second rotary oil cylinder enables the device to be adjusted at multiple angles to adapt to different working scenarios.

[0027] By designing the control component into three parts: a disk base, a double-spiral frame, and a linkage pressing frame, after fixing the disk base on the slide rail base during use, it can be rotatably installed on the disk base through the double-spiral frame, and the synchronous connecting rods at the upper ends of the two groups of linkage pressing frames are connected to the double-spiral frame. Through the cooperation of the eccentric groove and the synchronous connecting rod, the rotational motion is converted into the synchronous linear motion of the two groups of linkage pressing frames. When the telescopic oil cylinder two drives the double-spiral frame to rotate, it can drive the synchronous movement of the linkage pressing frames at both ends, that is, the two groups of linkage pressing frames can simultaneously clamp towards the center, thereby driving the synchronous clamping movement of the multi-functional frame, increasing the stability and operability of clamping use, and ensuring the stability of the overall horizontal movement of the linkage pressing frame by sliding the synchronous connecting rod at the lower end of the linkage pressing frame in the conduit base.

[0028] By designing both the control component and the equipment rotating frame into structures with multiple parts cooperating with each other, this not only facilitates the mutual assembly during installation, but also, compared with the overall structure, when a certain part is damaged, only the local part needs to be replaced, which can effectively reduce the equipment use and maintenance costs. The various structural designs of the positioning clamp group can meet the clamping requirements of blanks with different shapes and sizes. At the same time, by integrating the spraying system into the jaw head, the use position of the spraying system can be controlled through the jaw head during use. Before forging the die, the die can be sprayed with release agent, which can improve the release effect, and also improve the forging quality and the service life of the die.

[0035] Referring to Figure 5 , Figure 6 and Figure 7 As shown, the control component 6 includes a disk seat 61, a double-spiral rack 62, and two groups of linkage pressure racks 63 that cooperate with the movable slider 51. The disk seat 61 includes a chassis 611 and a central shaft 612. The chassis 611 is fixedly installed on the upper end surface of the slide rail seat 42. The central shaft 612 is vertically fixed at the center of the upper end surface of the chassis 611. The double-spiral rack 62 is rotatably installed on the central shaft 612, and a telescopic oil cylinder two 411 for adjusting the angle of the double-spiral rack 62 is installed on the main frame block 41. The two groups of linkage pressure racks 63 are installed on both sides of the double-spiral rack 62, and the double-spiral rack 62 adjusts the distance between the two groups of linkage pressure racks 63 by rotation. By designing the control component 6 into a disk seat 61, a double-spiral rack 62, and two groups of linkage pressure racks 63 that cooperate with the movable slider 51, the disk seat 61 is used as the positioning and installation mechanism of the double-spiral rack 62 during use. At the same time, by designing the disk seat 61 into a structure in which the chassis 611 and the central shaft 612 cooperate, the disk seat 61 is fixedly installed on the slide rail seat 42 during use, so that the double-spiral rack 62 can be stably sleeved on the central shaft 612 to achieve stable rotational installation. The angle of the double-spiral rack 62 can be adjusted by the telescopic oil cylinder two 411 during use. The double-spiral rack 62 adjusts the distance between the two groups of linkage pressure racks 63 by rotation, thereby controlling the distance between the two groups of multi-functional racks 5, achieving precise adjustment of the distance between the multi-functional racks 5, and then controlling the clamping width of the positioning clip group 7 through the multi-functional rack 5 to adapt to workpieces and products of different sizes.

[0036] Referring to Figure 5 , Figure 6 and Figure 7As shown in the figure, the double spiral frame 62 includes a central sleeve 621, a driving disk 622 and a limiting top disk 623. The central sleeve 621 is sleeved and installed on the central shaft 612. An outer arm rod 624 connected to the second telescopic oil cylinder 411 is fixedly installed on the outer side surface of the central sleeve 621. Both the driving disk 622 and the limiting top disk 623 are sleeved and fixed on the central sleeve 621. Two groups of eccentric grooves 625 are provided on the driving disk 622. The linkage pressing frame 63 includes a right-angle frame 631, a pressing slide rod 632 and a synchronous connecting rod 633 slidably installed in the eccentric groove 625. The pressing slide rod 632 is slidably installed in the conduit seat 431. One end of the pressing slide rod 632 supports on the movable slider 51, and the other end of the pressing slide rod 632 is fixedly connected to the right-angle frame 631. The synchronous connecting rod 633 is fixedly installed at the end of the right-angle frame 631 away from the pressing slide rod 632. By designing the double spiral frame 62 into a structure in which the central sleeve 621, the driving disk 622 and the limiting top disk 623 cooperate, when in use, the central sleeve 621 of the double spiral frame 62 is sleeved on the central shaft 612, ensuring the stable rotation of the double spiral frame 62. The outer arm rod 624 is connected to the second telescopic oil cylinder 411, realizing the driving of the double spiral frame 62 by the second telescopic oil cylinder 411. The eccentric groove 625 on the driving disk 622 cooperates with the synchronous connecting rod 633 of the linkage pressing frame 63. When the double spiral frame 62 rotates, the rotational motion can be converted into the linear motion of the linkage pressing frame 63, thereby controlling the sliding of the multi-functional frame 5. And the limiting top plate is provided to limit the upper end of the synchronous connecting rod 633, ensuring that the synchronous connecting rod 633 can slide stably in the eccentric groove 625.

[0037] By designing the control assembly 6 into a structure consisting of a disk seat 61, a double spiral frame 62 and a linkage pressing frame 63, after being fixed on the slide rail seat 42 through the disk seat 61 during use, it can be rotatably installed through the double spiral frame 62 on the disk seat 61, and the synchronous connecting rods 633 at the upper ends of the two groups of linkage pressing frames 63 are connected to the double spiral frame 62. Through the cooperation of the eccentric groove 625 and the synchronous connecting rod 633, the rotational motion is converted into the synchronous linear motion of the two groups of linkage pressing frames 63. When the second telescopic oil cylinder 411 drives the double spiral frame 62 to rotate, the synchronous movement of the two ends of the linkage pressing frames 63 can be realized. (The central sleeve 621, the driving disk 622 and the limiting top disk 623 are fixed to each other, so they can rotate synchronously on the central shaft 612 of the disk seat 61. The limiting top disk 623 limits the upper end of the synchronous connecting rod 633, ensuring that the lower end of the synchronous connecting rod 633 is stably inserted into the eccentric groove 625 of the driving disk 622), that is, the two groups of linkage pressing frames 63 can clamp towards the center simultaneously, increasing the stability and operability of the clamping use, and ensuring the stability of the overall horizontal movement of the linkage pressing frame 63 by slidably installing the synchronous connecting rods 633 at the lower ends of the linkage pressing frames 63 in the conduit seat 431.

[0038] Meanwhile, a set of telescopic oil cylinders cooperating with the double-spiral frame 62 is used as the driving source, which has better synchronization performance compared with the traditional method of installing two groups of oil cylinders on both sides for driving. Moreover, after installing the double-spiral frame 62 at the center of the upper end face of the slide rail base 42, no matter how the precision of the telescopic oil cylinders decreases (the precision will decrease due to wear and oil leakage after long-term use of the oil cylinders), the linkage pressure frames 63 on both sides can ensure that the multi-functional frames 5 at both ends are always in a symmetrical state, avoiding the situation of workpiece offset and instability during work.

[0039] Furthermore, by designing both the control component 6 and the equipment rotary frame 4 into structures composed of multiple parts cooperating with each other, it is not only convenient for better mutual assembly during installation, but also compared with the overall structure, when a certain part is damaged, only the local part needs to be replaced, which can effectively reduce the equipment use and maintenance costs.

[0040] Refer to Figure 8 、 Figure 9 and Figure 10 As shown, the positioning clamp group 7 includes a bent and expanded frame 71, a positioning table 72 and an insertion plate rod 73. One end of the bent and expanded frame 71 is fixedly installed on the outer side surface of the outer seat plate 52, the positioning table 72 is fixedly installed at the other end of the bent and expanded frame 71, the insertion plate rod 73 is fitted and installed on the inner side surface of the positioning table 72, and a rotary oil cylinder three 720 for driving the insertion plate rod 73 to flip is also fixedly installed on the outer side surface of the positioning table 72. A reinforcing bent plate 731 is fixedly installed on the upper end surface of the insertion plate rod 73. A limiting slider is integrally formed at the head of the reinforcing bent plate 731, and a limiting arc groove 721 for sliding and installing the limiting slider is formed on the inner side surface of the positioning table 72. By designing the positioning clamp group 7 into a structure composed of the bent and expanded frame 71, the positioning table 72 and the insertion plate rod 73 cooperating with each other, during use, the bent and expanded frame 71 of the positioning clamp group 7 connects the outer seat plate 52 and the positioning table 72, increasing the working range of the positioning table 72, and facilitating the positioning clamp group 7 to clamp larger-sized workpieces after being installed on the positioning table 72. At the same time, the rotary oil cylinder three 720 can drive the insertion plate rod 73 to flip, facilitating the up and down fine adjustment of the insertion plate rod 73 when clamping the workpiece on the forming die 10, making it more convenient for the insertion plate rod 73 to be inserted into both sides of the workpiece for clamping. At the same time, the head of the insertion plate rod 73 adopts an inclined surface structure, which further increases the ability of the insertion plate rod 73 to insert into the gap. The insertion plate rod 73 is slidably connected to the positioning table 72 through the reinforcing bent plate 731 and the limiting arc groove 721, making it more stable when the rotary oil cylinder three 720 drives the insertion plate rod 73 to flip and adjust, and improving the stability of the insertion plate rod 73 when clamping the workpiece.

[0041] Embodiment 2 Refer to Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15As shown, the positioning clamp group 7 includes a positioning base 701, a guiding shell 702, a telescopic rod 703 and a jaw head 8. On both sides of the positioning base 701, there are clamping plates 700 fixedly connected to the outer seat plate 52. The clamping plates 700 are integrally formed with the positioning base 701. The guiding shell 702 is fixedly installed on the front end face of the positioning base 701. The telescopic rod 703 is slidably installed in the guiding shell 702, and an internally threaded tube 704 is fixedly installed in the middle of the telescopic rod 703. A threaded rod 705 that cooperates with the internally threaded tube 704 is arranged in the guiding shell 702, and a built-in motor 706 for driving the threaded rod 705 to rotate is fixedly installed in the positioning base 701. The jaw head 8 is sleeved and fixedly installed at the outer end of the telescopic rod 703. By designing the positioning clamp group 7 into a structure in which the positioning base 701, the guiding shell 702, the telescopic rod 703 and the jaw head 8 cooperate, during use, the positioning base 701 of the positioning clamp group 7 is fixedly connected to the outer seat plate 52 through the clamping plates 700, and locking bolts can be installed on the lower end face of the clamping plates 700. After being installed on the outer seat plate 52, it can be locked by rotating the locking bolts, which is convenient for quick disassembly and assembly operations. The guiding shell 702 provides guidance for the sliding of the telescopic rod 703. The built-in motor 706 drives the threaded rod 705 to rotate, and drives the telescopic rod 703 to extend and retract through the internally threaded tube 704, so as to realize the telescopic movement of the jaw head 8, and can be precisely adjusted according to the position of the forming die 10.

[0042] Refer to Figure 11 , Figure 16 , Figure 17 and Figure 18As shown, the jaw head 8 includes a head seat 81, a bottom support plate 82, and two groups of double-layer jaws 83. A housing 811 connected to the telescopic rod 703 is provided on the rear end face of the head seat 81. The bottom support plate 82 is fixedly installed on the lower end face of the head seat 81. Two rotating shaft rods 812 for installing the double-layer jaws 83 are rotatably installed on the head seat 81. The two rotating shaft rods 812 are connected by two meshing gear disks 813. One end of the double-layer jaw 83 is sleeved and fixed on the rotating shaft rod 812, and an anti-slip clamping block 831 is integrally formed at the other end of the double-layer jaw 83. A fourth rotary oil cylinder 821 for driving the rotating shaft rod 812 to rotate is also fixedly installed on the bottom support plate 82. By designing the jaw head 8 into a structure in which the head seat 81, the bottom support plate 82, and the double-layer jaws 83 cooperate, when in use, the head seat 81 of the jaw head 8 is connected to the telescopic rod 703 through the housing 811. By rotatably installing the rotating shaft rod 812 on the head seat 81, it is convenient to install the double-layer jaws 83 through the rotating shaft rod 812, ensuring that the double-layer jaws 83 can rotate and be clamped during use. The two rotating shaft rods 812 are connected by the gear disks 813, ensuring the synchronous rotation of the two groups of double-layer jaws 83 and facilitating stable rotational opening and closing clamping operations. The setting of the bottom support plate 82 facilitates the stable installation of the fourth rotary oil cylinder 821. During use, the fourth rotary oil cylinder 821 drives the rotating shaft rod 812 to rotate, enabling the double-layer jaws 83 to perform opening and closing actions. The setting of the anti-slip clamping block 831 increases the stability of clamping and can firmly clamp the forming die 10.

[0043] Refer to Figure 11 、 Figure 12 and Figure 13As shown in the figure, a positioning groove 822 is formed on the lower end surface of the anti-slip clamping block 831. A buffer housing 91 is fixedly installed in the positioning groove 822. One end of the buffer housing 91 is provided with an arc-shaped housing 911 which is communicated therewith. And a liquid inlet pipe 912 which is matched therewith is arranged on the upper end surface of the buffer housing 91. A plurality of spray heads 914 are uniformly installed on the lower end surface of the arc-shaped housing 911. A temperature-resistant connecting pipe 913 which is communicated with the liquid inlet pipe 912 is fixedly installed between the double-layer clamping jaws 83. Two groups of box-shaped brackets 312 are symmetrically installed on the upper end surface of the machine base plate 31. A liquid storage tank 9 is fixedly installed between the two groups of box-shaped brackets 312. A spray pump 92 is also fixedly installed on the machine base plate 31. The liquid suction port of the spray pump 92 is connected with the liquid storage tank 9. And a spiral water supply hose 921 which is communicated with the temperature-resistant connecting pipe 913 is installed at the liquid discharge port of the spray pump 92. By forming the positioning groove 822 on the lower end surface of the anti-slip clamping block 831, it is convenient to stably install the buffer housing 91 through the positioning groove 822. At the same time, the buffer housing 91 and the arc-shaped housing 911 on the lower end surface of the bottom support plate 82 form a spray system. During use, the spray pump 92 transports the demolding liquid in the liquid storage tank 9 to the spray heads 914 through the spiral water supply hose 921 and the temperature-resistant connecting pipe 913, and sprays the forming die 10 before die forging, which plays a role in improving the demolding effect and improves the die forging quality and operability. And by uniformly installing a plurality of spray heads 914 on the lower end surface of the arc-shaped housing 911 to increase the spraying efficiency, and through the arrangement of the spiral water supply hose 921, it is convenient for the equipment rotating frame 4 not to affect the normal liquid supply use at a certain rotation angle.

[0044] Working principle: During actual installation, first install the die forging seat 1 at a suitable working position to ensure its stability. Then install the mechanical seat 2 on the outside of the die forging seat 1, rotatably install the rotating seat 201 on the mechanical seat 2, and connect the first rotating oil cylinder 202 so that the first rotating oil cylinder 202 can drive the rotating seat 201 to rotate. Horizontally and fixedly install the adjustable machine base 3 on the upper end surface of the rotating seat 201, rotatably install the equipment rotating frame 4 on the outer end surface of the adjustable machine base 3, and connect the second rotating oil cylinder 30 to ensure that the second rotating oil cylinder 30 can drive the equipment rotating frame 4 to rotate. Slide and install two groups of multi-functional frames 5 on the front end surface of the equipment rotating frame 4, install the control component 6 on the upper end surface of the equipment rotating frame 4, and finally install the positioning clamp group 7 on the multi-functional frame 5.

[0045] According to the position and size of the blank for forming, start the first rotary oil cylinder 202 to drive the rotary seat 201 to rotate and adjust the circumferential angular position of the adjustable machine base 3. Then start the second rotary oil cylinder 30 to drive the equipment rotary frame 4 to rotate on the adjustable machine base 3 to further adjust the angle of the equipment. At the same time, start the first telescopic oil cylinder 311 to drive the vertical plate seat 33 to move horizontally and adjust the horizontal position of the equipment rotary frame 4 to make the positioning clamp group 7 approach the workpiece blank. Then start the second telescopic oil cylinder 411 to adjust the angle of the double spiral rotary frame 62. When the double spiral rotary frame 62 rotates, it drives the linkage pressure frame 63 to move through the eccentric groove 625 and the synchronous connecting rod 633, thereby adjusting the distance between the two groups of multi-functional frames 5 so that the positioning clamp group 7 can accurately clamp the workpiece blank. After clamping the workpiece blank, place it in the forming die 10 and perform forging through the die. During the forging process, the angle and direction of the workpiece can be adjusted through the positioning clamp group 7. After forging is completed, take it out through the positioning clamp group 7 and place it in the subsequent section.

[0046] During use, it is necessary to select a suitable positioning clamp group 7 for installation and use according to the shape and positioning requirements of the forming die 10. When the workpiece size is large, it is necessary to use the positioning clamp group 7 including the bending and expanding frame 71, the positioning table 72, and the plug rod 73. Start the third rotary oil cylinder 720 to drive the front end of the plug rod 73 to turn downward so that the front end of the plug rod 73 can be better inserted between the workpiece and the die. When the workpiece size is small, the positioning clamp group 7 including the positioning seat 701, the guide shell 702, the telescopic rod 703, and the clamping jaw head 8 can be used. Start the built-in motor 706 to drive the threaded rod 705 to rotate, drive the telescopic rod 703 to expand and contract through the internal threaded pipe 704, and make the clamping jaw head 8 approach the forming die 10. Then start the fourth rotary oil cylinder 821 to drive the double-layer clamping jaw 83 to open and close to clamp the workpiece for processing.

[0047] During the die forging process, before the workpiece is placed in the forming die 10, the spraying pump 92 can be started to spray the release agent on the forming cavity of the die. After starting the spraying pump 92, the release agent in the liquid storage tank 9 can be transported to the spray head 914 through the spiral water supply hose 921 and the temperature-resistant connecting pipe 913 to spray the forming die 10.

Therefore, the present invention is not limited to the above specific embodiments. Any obvious improvements, substitutions, or variations made by those skilled in the art on the basis of the present invention fall within the protection scope of the present invention.
