Description

Technical Field

[0001] The present invention relates to the technical field of forging and rolling, and in particular to a forging and rolling device and a forging and rolling process thereof for processing large steel materials. Background Art

[0002] Rolling and forging are both methods of processing metal materials. Rolling is a metal processing method that reduces the cross-section of the material and increases the length by extruding the material. Forging is a processing method that applies pressure to the metal to cause the metal to undergo plastic deformation. Compared with rolled parts, the deformation degree of forgings is greater than that of rolled parts. The mechanical properties and plasticity of forgings are higher than those of rolled parts. However, the processing cost of forgings is higher and the processing efficiency is relatively low.

[0003] A metal alloy material forging and rolling device disclosed in the patent application with reference publication number CN116000112A includes a processing box, three first brackets are arranged in the processing box, the upper ends of the three first brackets are fixedly connected with two lifting screws, the lifting screws are covered with threaded sleeves, the threaded sleeves pass through the upper end of the processing box and are rotatably connected thereto, the processing box is equipped with a driving mechanism for driving the threaded sleeves to rotate, three second brackets are arranged at the bottom of the processing box, and the three first brackets and the three second brackets are fixedly equipped with inclined alloy material rolling mechanisms. The present invention can guide the rolled metal plate to ensure the accuracy and effect of the rolling, and can guide metal plates of different widths, and at the same time, multiple inclined pressing rollers are arranged to press the metal plate in a stepped manner from left to right, which can reduce the load borne by each pressing roller, and at the same time, can ensure the rolling effect and realize the protection of the pressing rollers.

[0004] During the liquid die forging process, if there is too much coating or pouring is performed before it is dried, the coating may be brought into the liquid metal to form slag inclusions. At the same time, part of the coating or oxide scale may be squeezed into the surface of the workpiece when the punch is pressurized to form welding slag. When there is welding slag on the surface of the billet, direct forging may cause the welding slag to become a crack source during the forging process, resulting in cracks on the surface or inside of the billet, seriously affecting the performance of the billet. However, the existing manual grinding is too cumbersome and cannot guarantee safety. If equipment grinding is used, effective adjustment cannot be made for rectangular and round billets.

[0029] During specific implementation, when it is necessary to select the first transmission component or the second transmission component according to the shape of the steel billet, the driving motor is started, and the driving motor drives the rack 602. When the rack 602 passes through the installation frame 6 and is inserted into one of the locking frames 7, the rack 602 meshes with the third gear 702 inside the corresponding locking frame 7, and the third gear 702 drives the fixedly connected bidirectional screw rod 701 to rotate, and the bidirectional screw rod 701 drives the two outer sliding blocks 703 to move relative to each other.

When the locking plate 705 is close to the mounting frame 6, the plug plate 707 is inserted into the card slot provided on the outer side of the mounting frame 6, and the locking plate 705 on the other locking frame 7 is away from the mounting frame 6, thereby achieving the switching processing of the two groups between the first transmission assembly and the second transmission assembly, which can be adjusted and selected as needed; The switching process is performed when the two locking frames 7 on the first transmission assembly and the second transmission assembly are in a relative state.

[0033] In this embodiment, the adjustment component includes a base plate 504 set on the ground, and two support frames 501 are fixedly connected to the top of the base plate 504.

[0036] During specific implementation, by starting the fourth motor 910 on the mounting plate 9, the output shaft of the fourth motor 910 drives the fixedly connected rotating rod 901 to rotate, and the rotating rod 901 drives the cleaning sheet 902 between the two fixed disks 900 to rotate. The telescopic end of the electric telescopic rod 8 is extended and retracted, so that the cleaning sheet 902 continuously processes the surface of the steel billet, and drives the mounting frame 6 to move through the first transmission assembly or the second transmission assembly, thereby performing processing.

[0038] In specific implementation, when multiple cleaning sheets 902 are being polished, a large number of particles will inevitably adhere to the surface. Therefore, in this solution, when the rotating rod 901 drives the fixed plate 900 to rotate, it also drives the second rod 903 on one side of the cleaning sheet 902 to rotate around the rotating rod 901. When the cleaning sheet 902 contacts the steel billet, the fourth gear 905 on the second rod 903 meshes with the half gear ring 909.
