Description

Technical Field

[0001] This application relates to the field of casting correction and shaping technology, and in particular to a casting shaping device. Background Technology

[0002] Casting is a processing method in the machinery manufacturing industry that provides blanks for mechanical parts. Through casting, not only can the shape of mechanical parts be obtained, but the internal structure of the metal can also be improved, and the mechanical and physical properties of the metal can be enhanced. However, during the metal casting process, deformation of the raw materials themselves due to external forces or deformation caused during the processing often occurs, so straightening processing of the castings is necessary.

[0003] During the casting or heat treatment process, aluminum alloy castings, due to significant variations in wall thickness and large dimensions, are prone to thermal stress and deformation. To ensure the product dimensions meet the drawing requirements, deformed castings generally need to be reshaped using shaping equipment. Currently, for mass-produced castings, especially medium to large die-cast shells, dedicated shaping equipment is typically designed during product development. However, for multi-variety, small-batch, or rapidly prototyping prototypes, especially easily deformable pipe fittings, shaping currently relies mostly on manual hammering or simple back-pressing with pressure equipment. This shaping process suffers from uncontrollable precision and is prone to causing additional deformation during the process.

[0004] Therefore, there is an urgent need for a shaping device that can accommodate complex and varied pipe fittings and shells, and can precisely control the dimensions of the shaping process. Utility Model Content

[0005] The purpose of this application is to overcome the shortcomings of the prior art and provide a casting shaping device.

The main moving frame is mounted on the support base and moves along a first direction via a first driving mechanism. A main shaping cylinder is mounted on the main moving frame and slidably mounted on the main moving frame via a second driving mechanism. The main shaping cylinder moves along a second direction. The main shaping cylinder includes a shaping part for shaping the casting, which is capable of extending and retracting along a third direction. At least two lateral shaping mechanisms are symmetrically arranged on both sides of the shaping platform. Each lateral shaping mechanism includes a mounting base and a lateral cylinder mounted on the mounting base.

The threaded rod passes through the adjustment hole and is threadedly engaged with the adjustment hole.

[0010] Furthermore, the second drive mechanism includes a second drive motor and a transmission shaft connected to the second drive motor. The second drive motor is mounted on the main moving frame, and at least a portion of the main shaping cylinder is threadedly engaged with the transmission shaft.

[0011] Furthermore, the support base also includes mounting brackets symmetrically arranged on both sides of the shaping platform. The mounting brackets include support rods and limiting rods connected to the support rods. The support rods are installed perpendicularly to the shaping platform, and the axis of the limiting rods extends along a first direction. The mounting base is movably sleeved on the limiting rods through mounting holes.

[0012] Furthermore, the mounting base is provided with a vertical slide rail, and the lateral cylinder is provided with a slide groove that cooperates with the vertical slide rail, and the slide groove moves along the slide rail.

[0013] Furthermore, the shaping device also includes a rotary mechanism, which includes a first rotating gear and a second gear meshing with the first rotating gear. The first rotating gear is rotatably connected to the shaping platform, and the second gear is located at the end of the vertical rod away from the upper horizontal rod. The main moving frame rotates horizontally around the shaping platform through the rotary mechanism.

[0014] Furthermore, the casting forming device also includes a limiting component, which can cooperate with a T-slot provided on the forming platform to fix the casting.

[0015] Furthermore, the shaping platform is provided with a plurality of T-shaped grooves, at least one of the T-shaped grooves extending along a first direction and at least one of the T-shaped grooves extending along a second direction.

[0016] Furthermore, the limiting assembly includes at least two T-bolts and a connecting rod, one end of the T-bolt slidingly abutting against the T-slot, and the other end of the T-bolt being fixedly connected to the connecting rod.

[0017] The beneficial effects of this application are:

[0018] The casting forming device of this application achieves high flexibility, adaptability, and high-precision control against deformation through multi-degree-of-freedom mechanical design. The combination of the main moving frame, main forming cylinder, and lateral forming mechanism provides full-area pressure point coverage, enabling the forming of various complex castings. Simultaneously, the main forming cylinder and lateral cylinder apply force synchronously, avoiding casting distortion or deformation caused by unilateral force application and reducing the risk of stress concentration. Furthermore, the main moving frame can move along the first direction to one side of the forming platform, facilitating the hoisting of heavy castings and minimizing interference with the forming space. In addition, precise control via PLC enables precise control of cylinder stroke, pressure, and speed, preventing stress concentration during the forming process and further improving the casting forming quality.

[0030] like Figures 1 to 4 As shown in the figure, this application discloses a casting shaping device, including a support base 100, a main moving frame 300, and at least two lateral shaping mechanisms 700. The support base 100 is provided with a shaping platform 200 for placing the casting. The main moving frame 300 is slidably mounted on the support base 100 via a first driving mechanism 400, and the main moving frame 300 moves along a first direction. A main shaping cylinder 500 is provided on the main moving frame 300, and the main shaping cylinder 500 is slidably mounted on the main moving frame 300 via a second driving mechanism 600. The main forming cylinder 500 moves along a second direction; the main forming cylinder 500 includes a forming part 510 for forming the casting, the forming part 510 being able to extend and retract along a third direction; the lateral forming mechanisms 700 are symmetrically arranged on both sides of the forming platform 200, each of the lateral forming mechanisms 700 includes a mounting base 710 and a lateral cylinder 720 disposed on the mounting base 710, the mounting base 710 being movable along the first direction, the lateral cylinder 720 being slidably connected to the mounting base 710, and the sliding direction of the lateral cylinder 720 being a third direction.

[0031] like Figures 1 to 3As shown, the support base 100 serves as the basic frame of the entire forming device, capable of supporting all moving parts and the casting to be formed. The forming platform 200 is mounted on the support base 100 and is used to place the casting. The main moving frame 300 slides along the first direction (Y-axis direction) via the first drive mechanism 400, achieving horizontal movement along the forming platform 200. When hoisting heavier castings, the main moving frame 300 can be moved to the side of the forming platform 200 via the first drive mechanism 400, freeing up space above the forming platform 200 for workers to move the casting onto it. Furthermore, by moving the main moving frame 300, the position range of the main forming cylinder 500 on the forming platform 200 can be adjusted, ensuring that the main forming cylinder 500 can cover different areas of the forming platform 200. The main forming cylinder 500 is mounted on the upper crossbeam of the main moving frame 300. The main forming cylinder 500 can move along the second direction (X-axis direction) via the second drive mechanism 600. The forming part 510 of the forming cylinder can directly act on the surface of the casting to be formed along the third direction (Z-axis direction), applying pressure to complete the forming. Therefore, through the cooperation of the main moving frame 300 and the main forming cylinder 500, the forming part 510 can be positioned in three-dimensional space, thereby precisely controlling the position of the force application point and meeting the multi-area forming requirements of complex castings.

[0032] The casting forming device of this application also includes at least two lateral forming mechanisms 700, wherein the mounting bases 710 are symmetrically arranged on both sides of the forming platform 200 and can move along the first direction (Y-axis direction) to achieve position adjustment. The lateral cylinders 720 are mounted on the bases and can move along the third direction (Z-axis direction) to adjust the height of the lateral cylinders 720 on the forming platform 200 to adapt to the support or force application requirements of different lateral parts of the casting. At the same time, the pressure head of the lateral cylinders 720 can extend and retract along the second direction (X-axis direction) to achieve lateral limiting and forming adjustment of the casting.

[0033] By setting up a lateral forming mechanism 700, the casting to be formed can be laterally limited. Simultaneously, when the main forming cylinder 500 applies force to the casting, the lateral cylinder 720 provides lateral support, preventing the casting from twisting and deforming due to unilateral pressure. Furthermore, the position of the lateral cylinder 720 can be adjusted in multiple directions relative to the forming platform 200, providing support or applying forming force to various lateral parts of the casting, achieving full coverage of the casting. The extension distance of the forming section 510 of the main forming cylinder 500 and the extension distance of the pressure head of the lateral cylinder 720 in this application can be precisely controlled by a PLC control unit, preventing damage to the casting and ensuring forming quality.

[0034] The casting forming device of this application achieves high flexibility, adaptability, deformation prevention, and high-precision control through multi-degree-of-freedom mechanical design. The combination of the main moving frame 300, the main forming cylinder 500, and the lateral forming mechanism 700 provides full-area pressure point coverage, enabling the forming of various complex castings. Simultaneously, the main forming cylinder 500 and the lateral cylinder 720 apply force synchronously, avoiding casting distortion or deformation caused by unilateral force application and reducing the risk of stress concentration. Furthermore, the main moving frame 300 can move along the first direction to one side of the forming platform 200, facilitating the lifting of heavy castings and minimizing interference with the forming space. In addition, precise control via PLC enables precise control of the cylinder stroke, pressure, and speed, preventing stress concentration during the forming process and further improving the casting forming quality.

[0035] In one embodiment of this application, the main moving frame 300 includes vertical rods 310 symmetrically arranged on both sides of the support base 100 and an upper horizontal rod 320 connected to the vertical rods 310, and the main shaping cylinder 500 is slidably arranged on the upper horizontal rod 320 through a second driving mechanism 600.

[0036] like Figures 1 to 3 As shown, the main moving frame 300 adopts a gantry structure consisting of vertical rods 310 symmetrically arranged on both sides of the support base 100 and an upper horizontal rod 320 connecting the top of the two vertical rods 310. The main forming cylinder 500 is slidably set on the upper horizontal rod 320 through the second drive mechanism 600, which can build a high rigidity and high stability bearing platform to meet the process requirements of precise and safe forming of medium and large aluminum alloy tube castings.

[0037] The main moving frame 300 adopts a gantry structure. Specifically, vertical rods 310 are symmetrically arranged on both sides of the support base 100 and connected by horizontal rods 320 to form an overall frame. This gives the main moving frame 300 good mechanical symmetry and torsional resistance, which can increase the overall stability of the casting forming device. When the main forming cylinder 500 applies a large forming force, it can effectively suppress the elastic deformation and vibration of the main moving frame 300, ensuring a smooth and accurate force application process, avoiding positioning deviations caused by structural deformation of the main moving frame 300, and ensuring the forming accuracy of the casting by the main forming cylinder 500.

[0038] Furthermore, the main forming cylinder 500 is positioned on the upper crossbar 320, directly above the casting, with the force applied vertically downwards, aligning with the direction of gravity. This facilitates force transmission and control, while also providing ample space for casting hoisting and the operation of the lateral forming mechanism 700, enhancing operational convenience. The second drive mechanism 600 enables smooth sliding along the X-axis. This layout allows the main forming cylinder 500 to be freely positioned along the entire length of the upper crossbar 320, thus covering multiple force application points of the forming platform 200 in the X-direction.

[0039] In one embodiment of this application, the first drive mechanism 400 includes a first drive motor 410 and a threaded rod 420. The output shaft of the first drive motor 410 is fixedly connected to a transmission gear 430. The main moving frame 300 also includes a moving base rod 330. The moving base rod 330 is installed at the end of the vertical rod 310 away from the upper horizontal rod 320. The threaded rod 420 meshes with the transmission gear 430. The moving base rod 330 is provided with an adjustment hole. The threaded rod 420 passes through the adjustment hole and is threadedly engaged with the adjustment hole.

[0040] In one embodiment of this application, the first drive mechanism 400 includes a first drive motor 410, a transmission gear 430, and a threaded rod 420. Through the mutual cooperation between the threaded rod 420 and the movable base rod 330, the main moving frame 300 can move smoothly and accurately along the Y-axis direction.

[0041] Specifically, the first drive mechanism 400 employs a transmission method involving a motor, gears, and a screw. Power is output from the first drive motor 410 to drive the transmission gear 430 to rotate, which in turn drives the threaded rod 420, which meshes with it, to rotate synchronously. Since the threaded rod 420 and the adjusting hole on the movable base rod 330 are threadedly engaged, when the threaded rod 420 rotates, its helical motion is converted into linear movement of the movable base rod 330 along the Y-axis, thereby driving the entire main moving frame 300 to move linearly along the Y-axis. This process efficiently and stably converts the rotational motion of the motor into the linear feed motion of the main moving frame 300. The movable base rod 330, as a key component connecting the main moving frame 300 and the threaded rod 420, has an adjusting hole that forms a precise screw-nut transmission relationship with the threaded rod 420, ensuring smooth movement and positioning accuracy.

[0042] By using gear transmission to drive the threaded rod 420 to rotate, compared to directly driving the screw, the transmission torque can be effectively improved, enhancing the driving capability. This is particularly suitable for driving the heavy main moving frame 300, improving the load-bearing capacity and operational reliability of the casting forming device. Secondly, the threaded engagement of the threaded rod 420 with the adjusting hole forms a self-locking mechanism, which effectively prevents the main moving frame 300 from accidentally slipping due to external forces when the motor stops working or is powered off, ensuring the safety of the equipment in non-working states and during the forming process. Thirdly, this transmission method has high transmission accuracy and repeatability. Combined with the servo control system, it can achieve precise positioning of the main moving frame 300 in the Y-axis direction, providing a foundation for accurate alignment of the forming force application point. In addition, the drive mechanism is arranged at the bottom of the main moving frame 300, resulting in a compact structure that makes full use of the space under the support base 100, avoiding the occupation of the upper operating space of the forming platform 200, which is beneficial for the hoisting and unloading of castings. Furthermore, the mechanical transmission structure is mature and easy to maintain. Compared with hydraulic or pneumatic drives, it has higher response speed and control precision, and operates smoothly with low noise.

[0043] In one embodiment of this application, the second drive mechanism 600 includes a second drive motor 610 and a transmission shaft 620 connected to the second drive motor 610. The second drive motor 610 is mounted on the main moving frame 300, and the main shaping cylinder 500 is threadedly engaged with the transmission shaft 620 in at least a portion of its area.

[0044] like Figure 3 As shown, the second drive mechanism 600 includes a second drive motor 610 and a transmission shaft 620 connected to the output shaft of the motor. The axial direction of the transmission shaft 620 is consistent with the axial direction of the upper crossbar 320. The second drive motor 610 is fixedly mounted on the main moving frame 300. At least a portion of the mounting base of the main shaping cylinder 500 is threadedly engaged with the transmission shaft 620. The rotation of the transmission shaft 620 drives the main shaping cylinder 500 to move along the X-axis.

[0045] Specifically, when the second drive motor 610 starts, its output shaft drives the transmission shaft 620 to rotate. Since the mounting base of the main shaping cylinder 500 is threadedly connected to the transmission shaft 620, the rotational motion of the transmission shaft 620 is converted into linear movement of the main shaping cylinder 500 along the axial direction (i.e., the X-axis direction) of the transmission shaft 620. By controlling the forward and reverse rotation and the number of rotations of the second drive motor 610, the position of the main shaping cylinder 500 on the X-axis can be precisely controlled, achieving flexible coverage of the shaping force point in the width direction of the shaping platform 200.

[0046] By employing a motor-driven threaded transmission, high-precision positioning of the main shaping cylinder 500 can be achieved. Combined with a servo control system, micron-level repeatability can be achieved, ensuring the accuracy of the shaping force application point. Secondly, this transmission structure has high rigidity and stability, effectively resisting reaction forces when the main shaping cylinder 500 applies significant pressure, preventing positioning failure due to structural loosening or retraction, and ensuring the reliability of the shaping process. Thirdly, the drive motor is directly integrated into the main moving frame 300, forming a modular drive unit with a compact structure and short power transmission path, reducing energy loss and error accumulation in intermediate transmission links, and improving transmission efficiency and response speed. Furthermore, the threaded transmission itself has a certain self-locking capability, effectively preventing displacement of the main shaping cylinder 500 due to external forces or vibrations when the motor is stopped, enhancing the safety of equipment operation. Finally, this design allows the main forming cylinder 500 to move continuously within the full length of the upper crossbar 320, breaking through the limitations of fixed points or limited strokes, greatly improving the equipment's adaptability to castings of different sizes and structures, and truly achieving the technical goal of "flexible full-area coverage".

[0047] In one embodiment of this application, the support base 100 further includes mounting brackets 110 symmetrically arranged on both sides of the shaping platform 200. The mounting brackets 110 include support rods 111 and limiting rods 112 connected to the support rods 111. The support rods 111 are installed perpendicularly to the shaping platform 200. The axis of the limiting rods 112 extends along a first direction. The mounting base 710 is movably sleeved on the limiting rods 112 through mounting holes.

[0048] like Figure 1 As shown, the support base 100 also includes mounting brackets 110 symmetrically arranged on both sides of the shaping platform 200. Each mounting bracket 110 consists of a support rod 111 fixed perpendicularly to the shaping platform 200 and a limiting rod 112 connected to the support rod 111. The axial direction of the limiting rod 112 is consistent with the moving direction of the main moving frame 300 (i.e., the first direction, the Y-axis direction). The mounting base 710 of the lateral shaping mechanism 700 is movably sleeved on the limiting rod 112 through the mounting hole thereon.

[0049] Specifically, the mounting bracket 110 is vertically fixed to both sides of the forming platform 200 via support rods 111, forming a stable vertical support structure to ensure that the position of the limiting rod 112 in space is fixed and its direction is accurate. The limiting rod 112 extends along the Y-axis and serves as a guide rail for the mounting base 710. The mounting base 710 is fitted onto the limiting rod 112 through mounting holes and can slide along the limiting rod 112 under external force, thereby achieving position adjustment of the mounting base in the Y-axis direction. This structure allows the mounting base 710 of the lateral forming mechanism 700 to move freely within the lateral range of the forming platform 200, so as to flexibly adjust the layout of the lateral hydraulic cylinder 720 according to the length, shape, and deformation position of the casting to be formed, ensuring that its point of action is aligned with the key parts of the casting.

[0050] In the casting forming device of this application, the limiting rod 112 provides precise linear guidance for the mounting base 710, ensuring its stability and straightness when moving in the Y-axis direction, avoiding positioning deviations caused by skewness or swaying, and improving the accuracy of lateral support or force application. Secondly, this structure realizes the adjustability of the position of the lateral forming mechanism 700, which can adapt to pipe or shell castings of different lengths and structures, significantly improving the flexibility and versatility of the equipment. Thirdly, the mounting frame 110 is vertically fixed by the support rod 111, with a simple structure and high rigidity, which can effectively withstand the reaction force generated by the lateral cylinder 720 when applying pressure, ensuring the stability and safety of the forming process. In addition, the movable sleeve connection method makes the adjustment operation of the mounting base 710 simple, and the position adjustment can be completed without disassembly, improving the efficiency and ease of operation of the equipment. Finally, the symmetrically arranged mounting bracket 110, in conjunction with the double-sided lateral forming mechanism 700, can provide symmetrical or asymmetrical lateral support for the casting, effectively suppressing the torsion or lateral instability of the casting caused by uneven force on one side during the forming process, preventing the casting from deforming, and improving the forming quality of the entire forming device.

[0051] In one embodiment of this application, the mounting base 710 is provided with a vertical slide rail, and the lateral cylinder 720 is provided with a slide groove that cooperates with the vertical slide rail, and the slide groove moves along the slide rail.

[0052] like Figure 1As shown, the mounting base 710 is equipped with a vertical slide rail, and the lateral hydraulic cylinder 720 is equipped with a sliding groove that mates with the slide rail. The sliding groove can slide along the slide rail. Specifically, the vertical slide rail extends along the length (i.e., the vertical direction) of the mounting base 710, serving as a guide reference. The lateral hydraulic cylinder 720 forms a sliding engagement with the slide rail through its own sliding groove, allowing the lateral hydraulic cylinder 720 to slide up and down along the slide rail under external force, thereby adjusting its height. In actual operation, the operator can manually push the lateral hydraulic cylinder 720 along the slide rail to the target height according to the structural characteristics and deformation position of the casting to be shaped. Then, it is fixed in that position using a locking device (such as bolts, pressure blocks, etc.) to ensure that no displacement occurs during the application of force.

[0053] The casting forming device of this application provides high-precision vertical guidance for the lateral hydraulic cylinder 720 through the cooperation of the slide rail and the slide groove, ensuring smooth and undulating movement during height adjustment. This avoids uneven force distribution or localized stress concentration caused by tilted installation, ensuring the accuracy and safety of force application. Secondly, this structure achieves continuous height adjustment of the lateral hydraulic cylinder 720, covering multiple action points from low to high, and is suitable for pipe or shell castings with different wall thicknesses and structural heights, significantly enhancing the compatibility of the forming device with diverse castings. Thirdly, the slide rail and slide groove structure has high rigidity and load-bearing capacity, effectively resisting bending moment and shear force when the lateral hydraulic cylinder 720 applies lateral pressure, preventing deformation or failure, and ensuring the stability of the forming process. Finally, this design, combined with the ability of the mounting base 710 to move in the Y-axis direction, together constitutes a two-dimensional adjustable mechanism of the lateral forming mechanism 700 in the YZ plane, providing comprehensive lateral support and forming capability for complex castings, and effectively preventing twisting or secondary deformation caused by lateral instability during the forming process.

[0054] In one embodiment of this application, the shaping device further includes a rotary mechanism 800, which includes a first rotating gear 810 and a second gear 820 meshing with the first rotating gear 810. The first rotating gear 810 is rotatably connected to the shaping platform 200, and the second gear 820 is located at one end of the vertical rod 310 away from the upper horizontal rod 320. The main moving frame 300 rotates horizontally around the shaping platform 200 through the rotary mechanism 800.

[0055] like Figure 1 , Figure 2As shown, the forming device also includes a rotary mechanism 800, which consists of a first rotating gear 810 fixedly connected to the forming platform 200 and a second gear 820 installed at the bottom of the vertical rod 310 of the main moving frame 300. The two gears mesh with each other, and the rotational movement of the main moving frame 300 relative to the forming platform 200 is achieved through gear transmission. This structure can overcome the limitations of traditional forming equipment in the direction of force application, enabling the main forming cylinder 500 to apply force to the casting in a non-vertical direction, thereby adapting to the forming needs of castings with inclined structures, inclined surface deformation, or complex spatial contours, and significantly improving the process adaptability and spatial flexibility of the device.

[0056] Specifically, the second gear 820 serves as a fixed reference and is securely mounted on the lower end of the vertical rod 310 of the main moving frame 300 via a key or interference fit, forming a stationary center of rotation. The first rotating gear 810 is rotatably connected to the support structure of the shaping platform 200 (such as the moving base rod 330), and the second gear 820 precisely meshes with the first rotating gear 810. When it is necessary to adjust the angle of the main moving frame 300, the operator can manually rotate the first rotating gear 810, thereby causing the second gear 820 to roll along the gear ring of the first rotating gear 810, thus driving the entire main moving frame 300 to rotate horizontally (i.e., rotate in the XY plane) around the shaping platform 200. By controlling the rotation angle, the main moving frame 300 and the main shaping cylinder 500 mounted on it can be adjusted from their original orthogonal vertical state to a certain tilt angle, achieving precise force application to oblique or asymmetrical parts.

[0057] In one embodiment of this application, the casting forming device further includes a limiting component 900, which can cooperate with a T-slot 210 provided on the forming platform 200 to fix the casting. The forming platform 200 is provided with a plurality of T-slots 210, at least one of the T-slots 210 extending along a first direction and at least one of the T-slots 210 extending along a second direction. The limiting component 900 includes at least two T-bolts 910 and a connecting rod 920, one end of each T-bolt 910 slidingly abutting against the T-slot 210, and the other end of each T-bolt 910 being fixedly connected to the connecting rod 920.

[0058] like Figures 1 to 4As shown, the casting forming device also includes a limiting component 900, which cooperates with the T-slots 210 on the forming platform 200 to reliably fix the casting. Specifically, the forming platform 200 has multiple T-slots 210, extending in a first direction (Y-axis direction) and a second direction (X-axis direction), forming a grid layout on the forming platform 200. The limiting component 900 consists of at least two T-bolts 910 and a connecting rod 920. The head of the T-bolt 910 can slide and be positioned within the T-slot 210, and its rod extends upward and is fixedly connected to the connecting rod 920. The connecting rod 920 presses the casting to achieve clamping and fixing. This technical solution provides a casting clamping method that is simple in structure, flexible in adjustment, and highly adaptable, ensuring that the casting remains stable under multi-directional forces during the forming process and preventing displacement or loosening.

[0059] When the casting is moved onto the forming platform 200, the operator can select a suitable T-slot 210 based on the shape and key fixing points of the casting, slide the T-bolt 910 along the slot to the target position, and then install the connecting rod 920 on top of the T-bolt 910 and lock it. By adjusting the positions of multiple T-bolts 910 in the T-slots 210 in the X and Y directions, the layout of the connecting rod 920 can be flexibly configured to precisely cover the area of ​​the casting to be clamped. This process can achieve rapid clamping of castings of different shapes and sizes without changing fixtures or performing complex adjustments, and is especially suitable for multi-variety, small-batch samples or trial products.

[0060] By distributing the T-slots 210 in a grid pattern, the clamping flexibility is greatly improved, allowing the T-bolts 910 to be positioned at any location in the plane. This adapts to irregular, non-standard, or complex pipe and shell castings, solving the problem of poor compatibility of traditional fixing fixtures. Secondly, the sliding fit structure between the T-bolts 910 and the T-slots 210 allows for continuous adjustment of the clamping points without the need for pre-designed fixing holes, significantly improving the equipment's versatility and flexibility. Furthermore, this clamping method provides ample vertical and lateral space for the castings, without affecting the movement trajectory of the main forming cylinder 500 and the lateral cylinder 720, thus avoiding interference problems.
