[0001] This utility model relates to the field of plate rolling machine technology, and in particular to a large-diameter pipe anti-springback plate rolling machine. Background Technology

[0002] A plate rolling machine is a device that uses work rollers to bend and shape sheet metal. It can form parts of different shapes such as cylindrical and conical parts, and is a very important type of processing equipment.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When existing plate rolling machines roll and press large-diameter pipes, due to the large volume of the pipes, their rebound force is also relatively large. If they are not protected, they can easily cause injury to workers and damage to the plate rolling machine, reducing its service life. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing plate rolling machines have the disadvantage of easily injuring workers and damaging the plate rolling machine and reducing its service life when rolling large-diameter pipes due to the large volume and strong rebound force of the large-diameter pipes without protection. Therefore, we propose a large-diameter pipe anti-rebound plate rolling machine.

[0005] To achieve the above objectives, this application adopts the following technical solution: a large-diameter pipe anti-rebound plate rolling machine, comprising a frame: multiple rolling rollers are installed inside the frame, two hollow blocks are fixedly connected to both sides of the frame, a connecting rod is slidably connected inside the hollow block, a connecting plate is fixedly connected to the top of the connecting rod, a bulletproof plate is fixedly connected to the bottom of the connecting plate, a U-shaped block is fixedly connected to one end of the connecting rod, a through slot is opened on one side of the U-shaped block, an insertion rod is slidably connected inside the through slot, a pull plate is fixedly connected to one side of the insertion rod, multiple insertion slots are opened on one side of the hollow block, and a through groove is opened on one side of the hollow block.

[0006] Preferably, the interior of the insertion slot is slidably connected to the surface of the insertion rod, and the outer diameter of the insertion rod is adapted to the inner diameter of the insertion slot.

[0007] Preferably, a plurality of return springs are fixedly connected to one side of the pull plate, and one side of the return springs is fixedly connected to one side of the U-shaped block.

[0008] Preferably, the bulletproof plate is made of alloy steel.

[0009] Preferably, the hollow block has limit grooves at both ends of its inner cavity, and the connecting rod has limit blocks fixedly connected to both ends of its inner cavity.

[0010] Preferably, a buffer spring is fixedly connected to the bottom of the inner cavity of the hollow block, and a buffer plate is fixedly connected to the top of the buffer spring.

[0011] The technical effects and advantages of this utility model are as follows: In this invention, the operator moves the connecting rod to move the connecting plate and the bulletproof plate up and down. When it moves to the appropriate position, the operator can move the pull plate to insert the plug rod into the plug slot to fix the position of the bulletproof plate. At this time, the bottom of the bulletproof plate and the top of the rolling machine form a protective space, which can effectively prevent the large-diameter pipe from springing back when rolling the large-diameter pipe.

[0014] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and accompanying drawings are only exemplary descriptions of the technical solution of this utility model, and should not be regarded as the whole of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0015] Reference Figure 1 - Figure 4As shown, this utility model provides a technical solution: a large-diameter pipe anti-rebound plate rolling machine, including a frame 1; multiple rolling rollers 2 are installed inside the frame 1; two hollow blocks 3 are fixedly connected to both sides of the frame 1; a connecting rod 4 is slidably connected inside the hollow block 3; a connecting plate 5 is fixedly connected to the top of the connecting rod 4; a bulletproof plate 6 is fixedly connected to the bottom of the connecting plate 5; a U-shaped block 8 is fixedly connected to one end of the connecting rod 4; a through slot 9 is opened on one side of the U-shaped block 8; a plug-in rod 10 is slidably connected inside the through slot 9; the plug-in rod 10... A pull plate 11 is fixedly connected to one side. Multiple insertion slots 7 are opened on one side of the hollow block 3, and a through slot 17 is opened on one side of the hollow block 3. The operator moves the connecting rod 4 to move the connecting plate 5 and the bulletproof plate 6 up and down. When it moves to the appropriate position, the pull plate 11 can be moved to drive the insertion rod 10 to insert into the insertion slot 7 to fix the position of the bulletproof plate 6. At this time, the bottom of the bulletproof plate 6 and the top of the rolling machine form a protective space, which can effectively prevent the large-diameter pipe from springing back when rolling the large-diameter pipe.

[0016] Reference Figure 3 and Figure 4 As shown in this embodiment: the inside of the insertion groove 7 is slidably connected to the surface of the insertion rod 10, and the outer diameter of the insertion rod 10 is adapted to the inner diameter of the insertion groove 7. Since the outer diameter of the insertion rod 10 is adapted to the inner diameter of the insertion groove 7, the insertion rod 10 can be stably inserted into the insertion groove 7, fixing the position of the connecting rod 4, preventing the connecting rod 4 from shaking during use, and improving the overall stability.

[0017] Reference Figure 4 As shown in this embodiment: a plurality of return springs 12 are fixedly connected to one side of the pull plate 11. One side of the return spring 12 is fixedly connected to one side of the U-shaped block 8. By setting the return spring 12, when the worker pulls the pull plate 11 to drive the plug rod 10 out of the plug groove 7, the elasticity of the return spring 12 can make the pull plate 11 drive the plug rod 10 to automatically reset, which is convenient for the next use and improves work efficiency.

[0018] Reference Figure 2 As shown in this embodiment, the bulletproof plate 6 is made of alloy steel. Alloy steel has high strength and hardness, which can effectively resist external impact and protect the plate rolling machine from damage during operation. At the same time, alloy steel also has good wear resistance and corrosion resistance, which extends the service life of the bulletproof plate 6.

[0019] Reference Figure 3 and Figure 4As shown in this embodiment: both ends of the inner cavity of the hollow block 3 are provided with limiting grooves 13, and both ends of the connecting rod 4 are fixedly connected with limiting blocks 14. By setting the limiting blocks 14 and limiting grooves 13, the connecting rod 4 is limited, preventing the connecting rod 4 from shifting in the inner cavity of the hollow block 3, thus improving the overall stability.

[0020] Reference Figure 5 As shown in this embodiment: a buffer spring 15 is fixedly connected to the bottom of the inner cavity of the hollow block 3, and a buffer plate 16 is fixedly connected to the top of the buffer spring 15. By setting the buffer spring 15 and the buffer plate 16, a buffering effect can be formed on the bottom of the connecting rod 4. When the connecting rod 4 collides with the bottom of the inner cavity of the hollow block 3 during the movement, the elasticity of the buffer spring 15 can buffer the collision force and prevent the connecting rod 4 from being damaged.

[0021] Working Principle: The operator moves the connecting rod 4, causing the connecting plate 5 and the bulletproof plate 6 to move up and down. When they reach the appropriate position, the operator can move the pull plate 11 to insert the insertion rod 10 into the insertion slot 7, fixing the position of the bulletproof plate 6. At this time, the bottom of the bulletproof plate 6 and the top of the rolling machine form a protective space, effectively preventing the large-diameter pipe from springing back during rolling. Because the outer diameter of the insertion rod 10 matches the inner diameter of the insertion slot 7, the insertion rod 10 can be stably inserted into the insertion slot 7, fixing the position of the connecting rod 4 and preventing it from shaking during use, thus improving overall stability. A return spring 12 is provided so that when the operator pulls the pull plate 11 to disengage the insertion rod 10 from the insertion slot 7, the return spring 12 will return the rod to its original position. The elasticity of the pull plate 11 allows the plug rod 10 to automatically reset, facilitating future use and improving work efficiency. The alloy steel material has high strength and hardness, effectively resisting external impacts and protecting the plate rolling machine from damage during operation. At the same time, the alloy steel material also has good wear resistance and corrosion resistance, extending the service life of the bulletproof plate 6. By setting the limit block 14 and the limit groove 13, the connecting rod 4 is limited, preventing the connecting rod 4 from shifting in the inner cavity of the hollow block 3, thus improving the overall stability. By setting the buffer spring 15 and the buffer plate 16, a buffer effect can be formed on the bottom of the connecting rod 4. When the connecting rod 4 collides with the bottom of the inner cavity of the hollow block 3 during movement, the elasticity of the buffer spring 15 can buffer the collision force and prevent the connecting rod 4 from being damaged.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
