Technical Field

[0001] This utility model relates to the field of metal smelting technology, specifically a metal smelting and rolling mechanism. Background Technology

[0002] Metal smelting and rolling is a key process that uses mechanical pressure to induce plastic deformation in metal materials, thereby altering their geometry and mechanical properties. This process is widely used in the production of metal products such as sheets and pipes, and its core lies in achieving material densification and performance optimization through pressing and forming.

[0003] Publication number CN218903083U describes a metal rolling positioning mechanism that solves the problem that existing positioning mechanisms can only be used for rolling operations on metal workpieces of one specification, resulting in low versatility of the entire device. However, applying pressure with a single pressure bar can easily lead to local stress concentration on the workpiece, causing deformation or cracks.

[0004] Therefore, in order to address the shortcomings of the existing system, a metal smelting and rolling mechanism was proposed. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model achieves uniform transmission of metal calendering pressure by using a pressure plate, a central pressure rod, and an auxiliary pressure rod to work together, with the center and outer periphery acting synchronously.

[0029] Working principle: When using this metal smelting and rolling mechanism, the base 1 is first used as the basic support component. The support column 2 and the upper crossbeam 3 form a stable frame structure. The metal workpiece to be rolled is placed on the rolling base 9. The base plate 16 provides support and stability for the rolling base 9. The upper crossbeam 3 drives the pressure plate 4 to move downward. The pressure plate 4 drives the central pressure rod 5 and the auxiliary pressure rod 6 to descend synchronously. The central pressure rod 5 applies force to the center of the workpiece, and the auxiliary pressure rod 6 is evenly distributed around the central pressure rod 5, applying pressure to the outer periphery of the workpiece synchronously, thus realizing the pressure transmission of metal rolling.

[0030] Then, the pressure plate 4 cooperates with the limiting pressure plate 7 through the transition connecting plate 10. The ball bearing 11, buffer spring 12 and spring fixing seat 13 at the bottom of the pressure plate 4 constitute a buffer structure. During the descent of the pressure plate 4, the buffer spring 12 is fixed by the spring fixing seat 13, which, together with the ball bearing 11, reduces the friction between the pressure plate 4 and the transition connecting plate 10, and at the same time buffers the pressure to avoid the instantaneous impact of pressure causing workpiece deformation or equipment damage.

[0031] The limiting pressure plate 7 is connected to the long pressing base 9 through the support column 15. The limiting fit structure 8 ensures that the positions of the limiting pressure plate 7 and the long pressing base 9 correspond. The positioning slot 14 on the limiting pressure plate 7 performs initial positioning of the workpiece. The anti-deviation ear plate 17 restricts the displacement of the workpiece during the long pressing process to ensure the long pressing position accuracy. When the pressure plate 4 completes the pressure application, the return spring 18 on the limiting pressure plate 7 plays a role in pushing the limiting pressure plate 7 to reset and return to the initial position. The wear-resistant pad 19 reduces the friction loss of the limiting pressure plate 7 during the reset process and extends the service life of the component.

[0032] Throughout the entire rolling process, the frame consisting of base 1, support column 2, and upper crossbeam 3 provides stable support; pressure plate 4, central pressure rod 5, and auxiliary pressure rod 6 apply pressure; buffer structure ensures smooth pressure transmission; limit pressure plate 7, positioning slot 14, and anti-deviation ear plate 17 ensure accurate workpiece positioning; support column 15 and limit matching structure 8 maintain the positional relationship between components; base chassis 16 stabilizes the rolling base 9; and return spring 18 and wear-resistant pad 19 complete component reset and wear control.
