Technical Field

[0001] This application relates to the field of rolling machine equipment technology, and in particular to a mold and equipment for rolling forming. Background Technology

[0002] In modern industrial production, rolling forming equipment plays a crucial role, especially in the steel processing field. These machines bend steel into the desired circular cross-section through a series of precise mechanical actions. However, after this rolling process, the steel often needs to be transferred to another forming machine to ensure the accuracy of its shape and dimensions. This transfer process is not only laborious but also cumbersome, as operators must carefully move the processed steel to avoid any damage or deformation during handling.

[0003] Furthermore, frequent handling increases production costs and can impact the efficiency of the entire production line. Therefore, while roll forming equipment plays a significant role in improving steel processing efficiency, its subsequent transfer and shaping steps have become a bottleneck problem that urgently needs to be solved in industrial production. Utility Model Content

[0040] Reference Figure 1 A mold for rolling and forming includes a rolling punch 21 and a forming die 22. A forming mandrel 25 is provided between the rolling punch 21 and the forming die 22. The forming mandrel 25 has a circular cross-section. The lower center portion of the rolling punch 21 has a first arc groove 211 extending along the length of the rolling punch 21. The radius of the first arc groove 211 is the same as the radius of the forming mandrel 25. When the mold 20 is in use, a flat product that has not yet been rolled abuts against the forming mandrel 25 and the rolling punch 21. During forming, the rolling punch 21 moves downward, while the forming mandrel 25 remains stationary. The shape of the forming mandrel 25 and the first arc groove 211 bends the flat product in the first stage. Figure 1 As shown in the upper part, the top center of the forming die 22 has a second arc groove 221 extending along the length of the forming die 22. The radius of the second arc groove 221 is the same as the radius of the forming mandrel 25. The forming die 22 has ramp surfaces 222 on both sides of the second arc groove 221. The lower part of the ramp surface 222 and the surface of the second arc groove 221 continuously form a transition surface 223. The higher part of the ramp surface 222 extends toward the rolling punch 21 at a predetermined acute angle. At this time, the rolling punch 21 and the forming mandrel 25 move downwards. The part of the product that has not yet been rolled first contacts the ramp surface 222, so that the part performs the second stage of rolling. Until the rolling punch 21 and the forming die 22 are in contact, the rolling of the product is completed.

[0041] More specifically, the aforementioned predetermined acute angle ranges from 45° to 50°, with 50° being a more preferred setting. This angle setting allows for smoother and more efficient production during the second stage of product rolling, thereby improving production efficiency and product quality.

[0042] Based on the above structure, the mold 20 further includes:

[0043] The cutting punch 23 is installed on the side of the rolling punch 21 near the feeding direction and is used to cut off the material, remove the excess material and retain the material to be processed between the rolling punch 21 and the rolling die; the pressing punch 24 is installed on the side of the rolling punch 21 away from the feeding direction and is used to press the material when the cutting punch 23 cuts off the material.

[0044] The forming die 22 has receiving grooves on both sides of the second arc groove 221 for accommodating the cutting punch 23 and the pressing punch 24. When the forming die 22 and the rolling punch 21 are closed, the cutting punch 23 and the pressing punch 24 extend into the receiving grooves.

[0045] Mold 20 further includes:

[0046] The forming punch 27 has a first forming groove 271 at its lower center, which has an arc shape consistent with the radius of the forming mandrel 25. The forming die 28 has a second forming groove 281 at its lower center, which also has an arc shape consistent with the radius of the forming mandrel 25. When the forming punch 27 and the forming die 28 are closed, the first forming groove 271 and the second forming groove 281 can form a complete forming groove forming mandrel 26. The forming mandrel 26 is located between the forming punch 27 and the forming die 28. After the product is rolled, it needs to be placed on the forming mandrel 26 to shape the product.

[0047] An embodiment of this utility model also provides a device that employs a mold for rolling as described in any of the above claims, the device comprising:

[0048] The rolling machine 11 includes an upper rolling die holder 111 and a lower rolling die holder 112, with the upper rolling die holder 111 being movable up and down above the lower rolling die holder 112; the shaping machine 12 includes an upper shaping die holder 121 and a lower shaping die holder 122, with the upper shaping die holder 121 being movable up and down above the lower shaping die holder 122; the rolling machine 11 and the shaping machine 12 are arranged side by side along the feeding direction.

[0049] The forming mandrel 25 of the rolling machine 11 is supported by the first mandrel support 16, and the shaping mandrel 26 of the shaping machine 12 is supported by the second mandrel support 17. It should be noted that the forming mandrel 25 can move up and down on the first mandrel support 16, and the shaping mandrel 26 can move up and down on the second mandrel support 17. The specific movement is controlled by the equipment's computer software. This is prior art known to those skilled in the art, and the specific movement method will not be described in detail here.

[0050] The aforementioned equipment further includes a material transfer device, which comprises:

[0051] The transfer frame 13 is movable back and forth on the base 10 of the equipment along the feeding direction, such as... Figure 4 and Figure 5 As shown, the transfer frame 13 can move back and forth between the rolling machine 11 and the shaping machine 12. The specific movement method can be manual pushing or moving by electric push cylinder. A guide groove 15 is provided on the base 10, and a guide rail 133 is installed at the bottom of the transfer frame 13. The guide rail 133 is movably embedded in the guide groove 15, which makes it easy for the worker to push the transfer frame 13. The extension direction of the guide groove 15 is consistent with the feeding direction.

[0052] Furthermore, an adapter 131 is movably mounted on the transfer frame 13, and a rectangular groove 132 is formed on the adapter 131.

[0053] The material transfer device also includes a transfer shaft 14, which is mounted on the transfer frame 13. The first end of the transfer shaft 14 can be detachably connected to the forming mandrel 25 or the shaping mandrel 26, and the second end has a rectangular portion 141 that can be embedded in a rectangular groove 132 so that the transfer shaft 14 can be detachably connected to the transfer shaft 14. After the rectangular portion 141 is embedded in the rectangular groove 132, it is fixed or detached from the adapter seat 131 by bolts. The vertically movable adapter seat 131 can adapt to the vertical movement of the mandrel during the processing.

[0054] It should be noted that the diameter of the forming core 25 and the shaping core 26 are the same as the diameter of the transfer shaft 14, so as to ensure that the product can be pushed onto the transfer shaft 14 on the forming core 25 or the shaping core 26 by means of tools such as bamboo poles, or from the transfer shaft 14 onto the forming core 25 or the shaping core 26 by means of tools such as bamboo poles.

[0055] like Figures 3 to 5 As shown, during the rolling process, the forming mandrel 25 and the transfer shaft 14 are fixed by bolts. At this time, the forming mandrel 25 and the transfer shaft 14 are coaxial, and the vertically movable adapter 131 can adapt to the vertical movement of the mandrel during the process. Specifically, a spring cylinder 30 is installed in the transfer frame 13. The base end of the spring cylinder 30 is fixed in the adapter 131, and the moving end is connected to the adapter 131.

[0056] After the product rolling process is completed, the staff uses tools such as bamboo poles to push the product onto the transfer shaft 14, and then uses bolts to separate the transfer shaft 14 from the forming mandrel 25. Then, the transfer frame 13 is pushed to move the product onto the shaping machine 12, and the transfer shaft 14 is fixed to the shaping mandrel 26 with bolts. The staff uses tools such as bamboo poles to push the product from the transfer shaft 14 into the shaping mandrel 26, and then the shaping machine 12 performs the shaping process on it.

[0057] In addition, such as Figure 10 and Figure 11 As shown, the adapter 131 adopts a modular structure design. Because the diameters of the mandrels vary, the dimensions of the transfer shaft 14 also need to be adjusted accordingly, which directly affects the dimensions of the rectangular slot 132 and the rectangular section 141. Through modular design, modules of different sizes can be flexibly assembled according to the specific variations of the rectangular slot 132, thereby achieving a high degree of adaptability and customizability.

[0058] In the description of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0059] Those skilled in the art should understand that the above embodiments are merely for illustrative purposes and are not intended to limit the scope of this application. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of this application.
