Description

Technical Field

[0001] This utility model relates to the field of forging equipment technology, and in particular to a forging device for large flat-head forgings of transmission components of steel mill rolling mill equipment. Background Technology

[0002] A rolling mill is a piece of equipment used for rolling metals. It mainly consists of a work stand, transmission system, and auxiliary equipment. It applies pressure to metal billets through rolls, causing plastic deformation and thus processing the metal into products of various shapes and sizes. It is widely used in many industries, including steel and non-ferrous metals. To ensure high reliability of the transmission system, most of the transmission components of the rolling mill are made of forgings. This ensures stable operation of the rolling mill under long-term, high-intensity working conditions, providing a solid guarantee for efficient metal rolling production.

[0003] Currently, free forging is generally used in the processing of large flat forgings for rolling mills. However, free forging mainly relies on manual operation, which is labor-intensive and has low production efficiency. At the same time, due to the large size of the forgings, die forging can be inconvenient for demolding.

[0004] Therefore, there is an urgent need for forging equipment for large flat-head forgings of transmission components in steel mill rolling mills to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to solve the problem that in the current process of processing large flat-head forgings for rolling mills, free forging is generally used. However, free forging mainly relies on manual operation, which is labor-intensive and has low production efficiency. At the same time, due to the large size of the forgings, die forging will cause problems with demolding. Therefore, a forging device for large flat-head forgings of transmission components of steel mill rolling equipment is proposed.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A forging apparatus for a large flat-head forging of a transmission component of a steel mill rolling mill includes:

[0008] The mold body includes an upper mold and a lower mold that cooperate with each other. The upper mold and the lower mold are respectively provided with a first chamber and a second chamber. The first chamber and the second chamber together form a molding cavity. The molding cavity is provided with a first channel and a second channel on both sides.

[0009] A blocking mechanism, located on one side of the mold body, is used to block the second channel located on one side of the molding cavity;

[0010] The demolding mechanism, located on the other side of the mold body, is used to push the forgings out of the forming cavity after forging is completed;

[0011] The drive assembly includes a first driver for driving the lower mold to move vertically and a second driver for driving the sealing mechanism to move horizontally.

[0012] Furthermore, the sealing mechanism includes a first base connected to the moving end of the second driver, a connecting rod fixedly connected to the first base, and a plug that cooperates with the second channel is installed at the end of the connecting rod away from the first base.

[0013] Furthermore, the demolding mechanism includes a support column, inside which a hydraulic telescopic cylinder is installed. The moving end of the hydraulic telescopic cylinder is provided with a pusher head that is slidably connected to the support column, and the pusher head passes through one end of the support column.

[0014] Furthermore, the interior of the support column is provided with an installation groove that cooperates with the hydraulic telescopic cylinder and the pusher head.

[0015] Furthermore, the end of the support column that contacts the upper mold and the lower mold is provided with a high-temperature resistant protective pad, and the protective pad is provided with a through hole that cooperates with the pusher head.

[0016] Furthermore, the forging device for the large flat-head forging of the transmission component of the steel mill rolling mill equipment mentioned above also includes a guide mechanism, wherein multiple guide mechanisms are provided and are evenly installed at the edge of the mold body.

[0017] Furthermore, the guiding mechanism includes multiple mounting plates connected to the lower mold and multiple guide blocks connected to the upper mold. A cylindrical guide rod is fixedly mounted on the top of the mounting plate, and a U-shaped opening that matches the guide rod is provided on the guide block.

[0018] Furthermore, both the upper mold and the lower mold are provided with mutually cooperating venting grooves.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model, by setting up an upper mold, a lower mold, a first chamber, and a second chamber, can extrude and form a steel billet located in the forming chamber through the upper and lower molds in conjunction with a first driver during use. This reduces the manual operation process, lowers the labor intensity of workers, and effectively improves production efficiency. At the same time, the dimensional accuracy of the forgings is higher, and they can approach or reach the final size.

[0021] This invention, by setting up a sealing mechanism, a demolding mechanism, a first channel, and a second channel, allows the sealing mechanism to reset after forging is completed. The moving end of the demolding mechanism can extend into the forming cavity through the first channel to push the forging out of the forming cavity, thus completing the demolding process. This eliminates the need for workers to use other tools to pry the forging out of the forming cavity, effectively improving production speed and preventing workers from damaging the upper and lower molds during demolding.

It should be understood that the specific embodiments described below are not intended to limit the specific implementation of the technical solution of this utility model, but are merely possible implementations of the technical solution of this utility model. It should be noted that the descriptions of the positional relationships of the components herein, such as component A being located above component B, are based on the relative positions of the components in the illustrations and are not intended to limit the actual positional relationships of the components. Example 1

[0030] See Figure 1-5 , Figure 1A schematic diagram of a forging device for a large flat-head forging of a transmission component of a steel mill rolling mill is shown in the figure. As shown, the forging device for a large flat-head forging of a transmission component of a steel mill rolling mill according to Embodiment 1 includes a mold body and a drive assembly. The mold body includes an upper mold 1 and a lower mold 2 that cooperate with each other. The upper mold 1 and the lower mold 2 are respectively provided with a first chamber 6 and a second chamber 7. The first chamber 6 and the second chamber 7 together form a forming cavity. By setting the upper mold 1, the lower mold 2, the first chamber 6 and the second chamber 7, the steel billet located in the forming cavity can be extruded and formed by the upper mold 1 and the lower mold 2 in cooperation with the drive assembly during use. This reduces the manual operation process, lowers the labor intensity of the workers, effectively improves production efficiency, and at the same time, the dimensional accuracy of the forging is higher, which can approach or reach the final size.

[0031] Both the upper mold 1 and the lower mold 2 are provided with mutually cooperating venting grooves 8 to facilitate the discharge of air from the forming cavity during the extrusion process. The forming cavity is provided with a first channel 9 and a second channel 10 on both sides. A sealing mechanism 3 is provided on one side of the mold body to seal the second channel 10 located on one side of the forming cavity. A demolding mechanism 4 is provided on the other side of the mold body to push the forging out of the forming cavity through the first channel 9. By setting the sealing mechanism 3, the demolding mechanism 4, the first channel 9 and the second channel 10, the sealing mechanism 3 is reset after forging, and the moving end of the demolding mechanism 4 can extend into the forming cavity through the first channel 9 to push the forging out of the forming cavity and complete the demolding process. There is no need for workers to use other tools to pry the forging out of the forming cavity, which can effectively improve the production speed and also avoid workers damaging the upper mold 1 and the lower mold 2 during demolding.

[0032] The drive assembly includes a first driver and a second driver. In use, the first driver can drive the upper mold 1 to move up and down, thereby realizing the mold opening and closing operations. The second driver can drive the sealing mechanism 3 to move horizontally. During the extrusion forging process, the second driver drives the sealing mechanism 3 to extend into the interior of the second channel 10 to block the second channel 10. When demolding, the second driver drives the sealing mechanism 3 to reset, so that the second channel 10 is in an open state, thereby facilitating the demolding mechanism 4 to push out the forging.

[0033] like Figure 1 , Figure 2 and Figure 4As shown, the sealing mechanism 3 includes a first base 301 connected to the moving end of the second driver. A connecting rod 303 is fixedly connected to the first base 301, and a plug 302 that cooperates with the second channel 10 is installed at the end of the connecting rod 303 away from the first base 301. It should be noted that in use, the second driver can drive the plug 302 to move through the first base 301 and the connecting rod 303, thereby realizing the closing and opening of the second channel 10.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, the demolding mechanism 4 includes a support column 401. A hydraulic telescopic cylinder 402 is installed inside the support column 401. A pusher head 403 is slidably connected to the support column 401 at the moving end of the hydraulic telescopic cylinder 402. The pusher head 403 passes through one end of the support column 401. The support column 401 has an installation groove that cooperates with the hydraulic telescopic cylinder 402 and the pusher head 403. A high-temperature resistant protective pad is provided at the end of the support column 401 that contacts the upper mold 1 and the lower mold 2. A through hole that cooperates with the pusher head 403 is provided on the protective pad. It should be noted that when in use, activating the hydraulic telescopic cylinder 402 can drive the pusher head 403 to move, thereby pushing the forging through the first channel 9 into the interior of the forming cavity and causing the forging to be ejected from the second channel 10. The installation groove facilitates the installation of the hydraulic telescopic cylinder 402 and the pusher head 403. The protective pad is placed between the demolding mechanism 4 and the upper mold 1 and the lower mold 2 to protect the upper mold 1 and the lower mold 2.

[0035] like Figure 1 and Figure 2 As shown in the figure, the forging device for a large flat-head forging of a transmission component of a steel mill rolling mill according to Embodiment 1 also includes a guide mechanism 5. Multiple guide mechanisms 5 are evenly installed at the edge of the die body. It should be noted that the guide mechanisms 5 guide the upper die 1 as it moves.

[0036] like Figures 3-5As shown, the guiding mechanism 5 includes multiple mounting plates 501 connected to the lower mold 2 and multiple guide blocks 503 connected to the upper mold 1. A cylindrical guide rod 502 is fixedly mounted on the top of each mounting plate 501. Each guide block 503 has a U-shaped opening that matches the guide rod 502. It should be noted that during use, the guide rod 502 can slide within the opening on the guide block 503, thereby guiding the opening and closing of the upper mold 1 and the lower mold 2. Furthermore, the edges of the U-shaped openings on the guide blocks 503 are rounded to ensure smoother sliding of the guide rod 502.

[0037] Working principle:

[0038] This utility model provides a forging device for large flat-head forgings of transmission components in steel mill rolling mills. In use, the billet is placed into the second chamber 7 on the lower die 2. Then, the second driver is activated to move the sealing mechanism 3 to block the second channel 10. Then, the first driver moves the upper die 1 towards the lower die 2, so that the billet is squeezed and formed in the forming cavity. After forming, the second driver drives the sealing mechanism 3 to reset, so that the second channel 10 is in an open state. The moving end of the demolding mechanism 4 extends into the interior of the forming cavity through the first channel 9 to push the forging to move, so that the forging is initially separated from the upper die 1 and the lower die 2. Then, the first driver drives the upper die 1 to rise, so that the upper die 1 and the lower die 2 are separated. The demolding mechanism 4 continues to push the forging to be removed from the forming cavity through the second channel 10.

[0039] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
