Description

Technical Field

[0001] This utility model relates to the field of rolling mill production technology, specifically to an alloy cast steel rolling mill forming and ejection device. Background Technology

[0002] Rolls are one of the key components in rolling equipment, mainly used in the rolling process of metal processing. Alloy cast steel rolls are high-strength wear-resistant parts mainly used in the metal rolling process. They are made of alloy cast steel material. The main function of alloy cast steel rolls is to withstand pressure and friction during the rolling process, ensuring that the material can pass smoothly through the rolls of the rolling mill to achieve the required shape and size. Due to the high temperature, pressure and wear generated during the rolling process, alloy cast steel rolls are required to have strong wear resistance, thermal fatigue resistance, compressive strength and good thermal conductivity. The rolls bear huge pressure and friction from the metal material during the rolling process. The wear resistance and high strength of alloy cast steel rolls enable them to perform this task efficiently and for a long time. During the rolling process, alloy cast steel rolls press the metal material into the required shape. The rolls must not only withstand mechanical loads, but also quickly and effectively conduct high temperatures.

[0003] In the production of alloy cast steel rolls, the rolls need to be ejected from the mold by an ejector plate. A certain amount of adhesion easily forms between the formed product and the ejector plate. Conventional ejection equipment cannot easily eliminate this adhesion, making unloading difficult and time-consuming, significantly reducing work efficiency. Furthermore, conventional ejection equipment struggles to apply uniform thrust, resulting in uneven force on one side of the product, which can damage it during ejection and reduce product quality. To address these issues, a new alloy cast steel roll forming and ejection device is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, an alloy cast steel roll forming and ejection device is provided. This device addresses the issues of current alloy cast steel roll production methods, which require an ejector plate to push the roll out of the mold. The resulting product often exhibits an adhesive force with the ejector plate, making it difficult to eliminate this force and hindering the unloading process. This unloading process is time-consuming and significantly reduces efficiency. Furthermore, conventional ejection devices struggle to apply uniform thrust, leading to uneven force on one side of the product and potential damage during ejection, thus reducing product quality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an alloy cast steel roll forming ejection device, including a bottom mold, a fixing groove is provided inside the bottom mold, a connecting plate is slidably connected to the lower side of the fixing groove, an ejection push rod is fixedly installed at the center of the lower side of the bottom mold, the output end of the ejection push rod passes through the lower side of the bottom mold and is fixedly connected to the lower side of the connecting plate, an installation port is provided at each of the four corners of the upper side of the bottom mold, an auxiliary push rod is fixedly installed inside the installation port, a locking block is fixedly connected to the output end of the auxiliary push rod, an L-shaped locking groove is provided through the front side of the locking block, lifting rods are slidably connected to the left and right ends of the upper side of the bottom mold, a limit plate is fixedly connected to the upper side of the lifting rod, a connecting rod is fixedly connected to the upper side of the limit plate, an installation plate is fixedly connected to the upper side of the connecting rod, an adjusting push rod is fixedly installed on the outer side of the installation plate, and the output end of the adjusting push rod passes through the outer side of the installation plate and is fixedly connected to a push rod.

[0006] Preferably, a mold groove is provided at the upper middle position of the bottom mold.

[0007] Preferably, the lower inner side of the mold groove is provided with several lifting grooves.

[0008] Preferably, the lifting groove is internally slidably connected to an arc-shaped top plate.

[0009] Preferably, a fixing plate is fixedly connected to the lower side of the arc-shaped top plate, and the lower end of the fixing plate is fixedly connected to the upper side of the connecting plate.

[0010] Preferably, a groove is provided at the upper middle position of the top rod.

[0011] Preferably, a fixing rod is fixedly connected to each of the four lower corners of the bottom mold.

[0012] Compared with the prior art, the advantages of this utility model are as follows: By setting up a lifting rod, a limiting plate, a mounting plate, an adjusting push rod, a top rod, an auxiliary push rod, and a locking block, this utility model can effectively fix the ejected product. The opposing forces from top and bottom eliminate the adsorption force between the product and the top plate, facilitating the unloading process and effectively reducing the time spent on unloading, thus greatly improving work efficiency. By setting up an arc-shaped top plate, a fixing plate, a fixing groove, a lifting groove, a connecting plate, and an ejection push rod, the pushing force can be evenly distributed, preventing uneven pushing force on one side of the product. During ejection, the product is protected from damage, ensuring product quality. Attached Figure Description

Detailed Implementation

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] Reference Figure 1-2 As shown, an alloy cast steel roll forming and ejection device includes a bottom mold 1. Fixed rods 2 are fixedly connected to the four corners of the lower side of the bottom mold 1. A mold groove 3 is formed at the middle of the upper side of the bottom mold 1. Several lifting grooves 4 are formed on the lower side of the interior of the mold groove 3. An arc-shaped top plate 5 is slidably connected inside the lifting groove 4. A fixed plate 6 is fixedly connected to the lower side of the arc-shaped top plate 5. The lower end of the fixed plate 6 is fixedly connected to the upper side of the connecting plate 8. A fixed groove 7 is formed inside the bottom mold 1. A connecting plate 8 is slidably connected to the lower side of the fixed groove 7. An ejection push rod 9 is fixedly installed at the center of the lower side of the bottom mold 1. The output end of the ejection push rod 9 passes through the lower side of the bottom mold 1 and is fixedly connected to the lower side of the connecting plate 8. This effectively distributes the thrust applied by the ejection push rod 9 evenly to each arc-shaped top plate 5, ensuring a smooth ejection of the formed roll and preventing damage to the roll during ejection.

[0019] The bottom mold 1 has four mounting openings 10 at the four corners of its upper side. An auxiliary push rod 11 is fixedly installed inside the mounting opening 10. A locking block 12 is fixedly connected to the output end of the auxiliary push rod 11. An L-shaped slot 13 is opened through the front side of the locking block 12 to facilitate engagement with the push rod 19. Lifting rods 14 are slidably connected to the left and right ends of the upper side of the bottom mold 1. A limiting plate 15 is fixedly connected to the upper side of the lifting rod 14 to effectively control the height of the push rod 19 and ensure that the push rod 19 can be inserted into the L-shaped slot 13. A connecting rod 16 is fixedly connected to the upper side of the limiting plate 15. A mounting plate 17 is fixedly connected to the upper side of the connecting rod 16. An adjusting push rod 18 is fixedly installed on the outer side of the mounting plate 17. The output end of the adjusting push rod 18 passes through the outer side of the mounting plate 17 and is fixedly connected to the push rod 19. A groove 20 is opened in the middle of the upper side of the push rod 19 to prevent the roller from rolling.

[0020] Working principle: After the product is formed, the ejector rod 9 pushes the connecting plate 8 upward. The fixed plates 6 on the upper side of the connecting plate 8 are subjected to a uniform upward thrust to the arc-shaped top plate 5. Several arc-shaped top plates 5 gently eject the product upward. When the left and right ends of the product are separated from the mold groove 3 to a certain height, the opening of the L-shaped slot 13 is flush with the height of the ejector rod 19. The adjusting rod 18 pushes the ejector rod 19 into the interior of the L-shaped slot 13. The ejector rod 19 and the locking block 12 are engaged. The ejector rod 9 drives the connecting plate 8 downward. The lower side of the product abuts against the interior of the groove 20. The auxiliary rod 11 drives the locking block 12 and the ejector rod 19 to apply an upward thrust to the product. The ejector rod 9 applies a downward pull to the arc-shaped top plate 5. Under the opposite forces, the adsorption force between the product and the arc-shaped top plate 5 can be effectively counteracted. At the same time, it ensures that the product can be ejected from the mold, reducing the time spent on unloading.
