There are two positioning rods, which are of the same size and dimensions. The surface of the positioning rods is treated with anti-corrosion to significantly increase their service life. The positioning rods can move up and down under external force. The positioning rods are arranged vertically parallel to each other. The diameter of the upper connecting rod is larger than that of the lower connecting rod. The upper and lower connecting rods are round rods. The edge of the lower fixed template is blunted and ground. The upper and lower fixed templates are arranged horizontally parallel to each other. Compared with existing equipment, this setup can significantly increase the horizontality and stability of the cover.

[0004] The previous large-diameter segment production line used an integral casting cover plate device, which was prone to uneven pressure distribution during production, resulting in local inadequate pressing and insufficient density in some areas of the component. At the same time, excessive local pressure concentration may also cause excessive pressing of corresponding parts of the component, affecting the overall molding quality of the component.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1 to 5This utility model provides a technical solution: an integral casting cover plate device for a large-diameter pipe segment production line, including a workbench 1. Two side plates 4 are fixedly connected to the top of the workbench 1. A connecting plate 11 is fixedly connected to the top of each side plate 4. A top plate 5 is fixedly connected to the top of the connecting plate 11. A hydraulic rod 8 is fixedly connected to the top of the top plate 5. The output end of the hydraulic rod 8 passes through the top plate 5 and is fixedly connected to a mounting plate 9. A guide rod 7 is fixedly connected to the top of the mounting plate 9. The guide rod 7 slides through the interior of the top plate 5. There are two guide rods 7, located on the front and rear sides of the hydraulic rod 8, respectively. A pressing assembly 14 is provided at the bottom of the mounting plate 9. The pressing assembly 14 includes a rear support plate 142, which is fixedly connected to... At the bottom of mounting plate 9, a long support rod 143 is rotatably connected to the inner side of the rear support plate 142. A front support plate 141 is fixedly connected to the bottom of mounting plate 9. A short support rod 144 is rotatably connected to the inner side of the front support plate 141. A short support rod 144 is rotatably connected to the inner side of the long support rod 143. A gasket 145 is fixedly connected to the side of each of the two short support rods 144. A damping rod 146 and a return spring 147 are fixed between the two gaskets 145. The return spring 147 is sleeved on the outer side of the damping rod 146. An upper fixed mold 10 is fixedly connected to the center of the bottom side of mounting plate 9. There are four sets of pressing components 14. Pressing rollers 15 are rotatably connected between two adjacent long support rods 143. The two pressing rollers 15 are respectively close to the left and right sides of the top of the upper fixed mold 10. The hydraulic rod 8 fixed to the top of the top plate 5 provides vertical driving force for the device. When the hydraulic rod 8 is activated, its output end drives the mounting plate 9 connected to the bottom to move in the vertical direction. Two guide rods 7 fixed to the top of the mounting plate 9 are located on the front and rear sides of the hydraulic rod 8, respectively, and slide through the interior of the top plate 5. During the movement of the mounting plate 9, the guide rods 7 can limit the horizontal displacement of the mounting plate 9, ensuring that the mounting plate 9 always moves stably in the vertical direction. The four sets of pressing components 14 set at the bottom of the mounting plate 9 work together. In each set of pressing components 14, the rear support plate 142 is fixed to the bottom of the mounting plate 9 to provide rotational support for the long support rod 143, and the front support plate 141 is also fixed to the bottom of the mounting plate 9 to provide rotational support for the short support rod 144. The inner side of the long support rod 143 is rotatably connected to the short support rod 144 to form a movable linkage structure. Between the pads 145 fixed to the sides of the two short support rods 144, the damping rod 146 cooperates with the return spring 147. When the pressing component 14 contacts the component to be processed, the long support rod 143 and the short support rod 144 rotate around their respective pivot points. At this time, the return spring 147 can deform according to the force, providing a buffer for the pressing action. The damping rod 146 can slow down the deformation speed of the spring and avoid damage to the component due to excessive impact force. When the external force disappears, the return spring 147 returns to its original shape, driving the long support rod 143 and the short support rod 144 back to the initial position. The upper fixed mold 10, which is fixed in the center of the bottom side of the mounting plate 9, descends synchronously with the mounting plate 9 when the hydraulic rod 8 drives the mounting plate 9 to descend, realizing the positioning and pressing operation of the component.The pressing rollers 15, which are rotatably connected between two adjacent long support rods 143, are respectively attached to the left and right sides of the top of the upper fixed mold 10. When the long support rods 143 rotate, the pressing rollers 15 can roll along the surface of the component, which not only enhances the uniformity of pressing, but also reduces frictional damage between the component and the pressing assembly 14.

[0024] like Figures 1 to 5 As shown, multiple drive rollers 17 are rotatably connected to the inner side of the workbench 1, and a conveyor belt 18 is wound around the outer side of the drive rollers 17. A lower mold 16 is provided on the top of the conveyor belt 18. A drive motor 6 is fixedly connected to the outer side of the workbench 1. The output end of the drive motor 6 passes through the workbench 1 and is fixedly connected to the drive roller 17 on the left end. A buffer spring 12 is fixedly connected to the inner side of the side plate 4, and a guide plate 13 is fixedly connected to the outer side of the buffer spring 12. Support legs 2 are fixedly connected to the four corners of the bottom of the workbench 1, and anti-slip pads 3 are fixedly connected to the bottom of each support leg 2. The multiple drive rollers 17 rotatably connected to the inner side of the workbench 1, and the conveyor belt 18 wound around their outer sides form a material conveying channel. After the drive motor 6 fixed on the outer side of the workbench 1 starts, its output end drives the drive roller 17 on the left end to rotate. Since the multiple drive rollers 17 are linked through the conveyor belt 18, when the drive roller 17 on the left end rotates, it can drive the entire conveyor belt 18 to move in the horizontal direction, thereby realizing the smooth conveying of the lower mold 16 placed on the top of the conveyor belt 18, meeting the needs of continuous operation of the assembly line. The buffer spring 12 fixed inside the side plate 4 and the guide plate 13 connected to its outside play a guiding and buffering role during mold conveying. When the mold moves to the position of the guide plate 13 with the conveyor belt 18, if the mold deviates slightly, the guide plate 13 can correct the mold and keep it on the preset conveying path. If the mold collides with the guide plate 13, the buffer spring 12 will undergo elastic deformation to absorb the impact force generated by the collision, avoid the mold from direct rigid contact with the side plate 4 and thus prevent damage. At the same time, it can also reduce the noise generated by the collision. The support legs 2 fixed at the four corners of the bottom of the workbench 1 provide stable support for the entire device. The anti-slip pads 3 fixed at the bottom of the support legs 2 increase the friction between the support legs 2 and the ground, which can prevent the device from sliding due to vibration or external force during operation, and ensure the overall stability and safety of the device.

[0025] Working principle: After the device is started, the drive motor 6 fixed on the outside of the workbench 1 drives the transmission roller 17 on the left to rotate. Through the linkage of multiple transmission rollers 17 and the conveyor belt 18, the lower mold 16 at the top of the conveyor belt 18 is smoothly transported in the horizontal direction. During the transport process, the guide plate 13 connected to the buffer spring 12 on the inner side of the side plate 4 corrects the path of the lower mold 16. If a collision occurs, the buffer spring 12 absorbs the impact force to protect the mold. At the same time, the bottom support legs 2 and the bottom anti-slip pads 3 of the workbench 1 ensure the overall stability of the device. After the lower mold 16 is transported to the designated position, the hydraulic rod 8 at the top of the top plate 5 is activated. Its output end drives the mounting plate 9 to descend along the vertical guide direction of the guide rod 7. The upper fixed mold 10, centered on the bottom side of the mounting plate 9, descends accordingly to position and press the internal components of the lower mold 16. At the same time, among the four sets of pressing components 14 at the bottom of the mounting plate 9, the long support rod 143 supported by the rear support plate 142 and the short support rod 144 supported by the front support plate 141 rotate around the pivot point. The return spring 147 between the side pads 145 of the short support rod 144, together with the damping rod 146, provides pressing buffer. The pressing rollers 15 between the adjacent long support rods 143 are close to both sides of the upper fixed mold 10 and roll along the surface of the component to enhance the pressing uniformity and reduce friction damage. After the pressing operation is completed, the hydraulic rod 8 drives the mounting plate 9 to rise, the return spring 147 drives the long support rod 143 and the short support rod 144 to return to their original positions, and the conveyor belt 18 continues to transport the lower mold 16 to the next operation cycle.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
