Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more schemes or examples in a suitable manner.

[0033] As shown in Figures 1-10 The utility model discloses a high strength ball forming die for steelmaking, which comprises a support 1, a pre-pressing roller sleeve 3 and a forming roller sleeve 5. The pre-pressing roller sleeve 3 and the forming roller sleeve 5 are identical in shape, size and internal structure. The pre-pressing roller sleeve 3 is sleeved on a pre-pressing roller core 2, and the forming roller sleeve 5 is sleeved on a forming roller core 4. The pre-pressing roller core 2 and the forming roller core 4 provide mounting bases and rotating power for the pre-pressing roller sleeve 3 and the forming roller sleeve 5, respectively.

[0034] Sliding grooves are formed on the vertical columns on both sides of the support 1 for placing an upper bearing seat 9 and a lower bearing seat 12. The upper bearing seat 9 is used for supporting the pre-pressing roller core 2, and the lower bearing seat 12 is used for supporting the forming roller core 5. The upper bearing seat 9 is located directly above the lower bearing seat 12. The lower end of the lower bearing seat 12 is fixed on the crossbar of the support 1 by bolts. A plurality of cylindrical grooves are formed on the upper end of the lower bearing seat 12. The upper end of the upper bearing seat 9 is connected to the hydraulic rod of a hydraulic device 11 by bolts and connecting pieces. The base of the hydraulic device 11 is fixed on the bottom of the crossbeam, and the crossbeam is fixed on the top of the support 1 by bolts.

[0035] The upper end of the upper bearing seat 9 is provided with a plurality of cylindrical grooves, which are consistent in number and size with the grooves on the lower bearing seat 12, and are one-to-one corresponding in position. A strong spring 10 is arranged between the upper and lower grooves. The main function of the hydraulic device 11 is to adjust the position of the upper bearing seat 9 to control the distance between the upper bearing seat 9 and the lower bearing seat 12, thereby achieving the function of controlling the forming pressure of the ball. The main function of the strong spring 10 is to provide an upward supporting force for the upper bearing seat 9, thereby reducing the load of the hydraulic device 11, and ensuring that the pre-pressing roller sleeve 3 and the forming roller sleeve 5 will not easily collide, thereby avoiding the problem of damaged parts.

[0036] The pre-pressing roller sleeve 3 and the forming roller sleeve 5 are cylindrical, and a plurality of module grooves 13 are uniformly distributed on the surfaces thereof. Each module groove 13 is the same in shape and size, and the opening thereof is flush with the surface of the roller sleeve. A module 6 that completely matches the module groove 13 is precisely embedded in each module groove 13. The module 6 and the lower end of the module groove 13 are both provided with a pin hole that is consistent in size. After assembly, the axial lines of all the pin holes are collinear. A plurality of pin holes are arranged in a circumferential arrangement at both ends of the pre-pressing roller sleeve 3 and the forming roller sleeve 5, which are the same in shape and size as the module groove 13 and consistent in number with the number of module grooves 13. Each row of module grooves 13, modules 6, and corresponding pin holes at both ends are fixed by a positioning pin 8. The upper surface of each module 6 is arc-shaped, and after assembly, the arc surfaces of all the modules 6 can smoothly connect with the surfaces of the pre-pressing roller sleeve 3 and the forming roller sleeve 5. A ball bowl groove 7 is arranged at the central position of the upper end of each module 6, which is a semispherical groove.

[0037] The modules 6 embedded in the pre-pressing roller sleeve 3 and the forming roller sleeve 5 correspond to each other in position. The pre-pressing roller sleeve 3 and the forming roller sleeve 5 rotate relative to each other at the same speed. With the relative rotation of the pre-pressing roller sleeve 3 and the forming roller sleeve 5, the corresponding modules 6 can move synchronously and relatively to a specific position with extremely high precision, so that the openings of the ball bowl grooves 7 on the upper and lower modules 6 are tightly and perfectly pressed together, thereby achieving the expected forming or processing function.

[0038] The pre-pressing roller sleeve 3, the forming roller sleeve 5, and the module 6 are all made of metal with high strength and high wear resistance, so as to achieve good pressure resistance and wear resistance, and prolong the service life of the mold. Since the positioning pin 8 is mainly used to prevent the module 6 from falling off, it does not directly bear high-strength force, so a metal with general strength can be used.

[0039] Working principle: when the pre-press roller core 2 and the forming roller core 4 rotate relatively, the pre-press roller sleeve 3 and the forming roller sleeve 5 are rotated relatively, and the rotation speeds of the two are completely consistent, at this time, according to the pre-pressing requirements, the pressure of the hydraulic device 11 is adjusted, the upper bearing seat 9 is moved to the appropriate position, so as to ensure that the upper and lower modules 6 have enough pressing force. After the adjustment is completed, the raw materials are fed, when the raw materials pass through the pre-press roller sleeve 3 and the forming roller sleeve 5, they are accumulated in the ball bowl groove 7 on each module 6, when the corresponding ball bowl grooves 7 on the upper and lower sides rotate to the corresponding position, the raw materials in the ball bowl grooves 7 on the upper and lower sides begin to extrude each other, until the slots of the ball bowl grooves 7 on the upper and lower sides are tightly pressed together, the internal raw materials are compressed into a block, forming a spherical shape, and finally forming. Since the pre-press roller sleeve 3 and the forming roller sleeve 5 are still rotating, the formed ball is loosened, and due to the expansion force of the ball itself, it expands rapidly in the ball bowl groove 7, so that it is automatically discharged from the ball bowl groove 7. Because the raw materials have been formed under high pressure, even if they are loosened and discharged, they will not easily become loose.

[0040] If the module 6 is seriously worn, you only need to remove the corresponding positioning pin 8, then take out the module 6 that needs to be replaced, replace the new module 6, and finally install the positioning pin 8.

[0041] Each embodiment in the specification is described in a progressive manner, and the same and similar parts between each embodiment can be referred to each other. Each embodiment mainly describes the difference from other embodiments. Especially, for the system embodiment, since it is basically similar to the method embodiment, it is described more simply, and the related parts can be referred to the part of the method embodiment.

[0042] The above only describes the embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
