Description

TECHNICAL FIELD

[0001] The present application relates to the field of forging and rolling technology, in particular to a forging and rolling device for large steel processing and a forging and rolling process thereof. BACKGROUND

[0002] Rolling and forging are both methods of metal material processing. Rolling is a metal processing method that reduces the cross section of the material by extruding the material and increases the length. Forging is a processing method that applies pressure to metal to produce plastic deformation. Compared with rolling pieces, the deformation degree of forged pieces is greater than that of rolling pieces, and the mechanical properties and plasticity of forged pieces are higher than those of rolling pieces. However, the processing cost of forged pieces is relatively high, and the processing efficiency is relatively low.

[0003] Referring to the metal alloy material forging and rolling device disclosed in the patent application with the publication number CN116000112A, the device includes a processing box, three first supports are arranged in the processing box, two lifting screws are fixedly connected to the upper ends of the three first supports, threaded sleeves are threadedly connected to the outer surfaces of the lifting screws, the threaded sleeves penetrate the upper end of the processing box and are rotatably connected to the upper end of the processing box, the processing box is provided with a driving mechanism that drives the threaded sleeves to rotate, three second supports are arranged at the bottom of the processing box, and alloy material rolling mechanisms are fixedly installed on the three first supports and the three second supports and are arranged in an inclined manner. The present application can guide the rolling metal plate to ensure the accuracy and effect of rolling, guide metal plates of different widths, and set multiple inclined pressing rollers to press the metal plate in a stepped manner from left to right, thereby reducing the load borne by each pressing roller, ensuring the rolling effect, and protecting the pressing rollers.

[0004] During the liquid die forging process, if too much paint is applied or the paint is not dry before pouring, the paint may be brought into the liquid metal, forming slag. Meanwhile, part of the paint or scale may be squeezed into the surface layer of the workpiece when the punch is pressed, forming welding slag. When the surface of the steel billet has welding slag, if direct forging and rolling is performed, the welding slag may become a crack source during the forging and rolling process, causing cracks on the surface or inside of the steel billet, which seriously affects the performance of the steel billet. However, the existing manual polishing is too tedious and cannot guarantee safety, and if equipment polishing is used, it cannot effectively adjust the rectangular steel billet and the circular steel billet.

[0005] Therefore, it is necessary to provide a forging and rolling device for large steel processing and a forging and rolling process thereof to solve the above technical problems. SUMMARY

The multiple second lead screws (903) pass through the fixed disk (900) and are rotatably connected to the fixed disk (900). Each of the multiple second lead screws (903) has a lifting block (904) connected to its outer side via a ball nut pair. Each of the multiple cleaning plates (902) has a scraper (906) on both sides. The scraper (906) passes through the lifting block (904) and is slidably connected to the lifting block (904). A connecting rod (908) is fixedly connected between two scrapers (906). A guide plate (907) is provided between the second lead screw (903) and the guide plate (907) is fixedly connected to the fixed plate (900). A limiting groove is opened on the outer side of the guide plate (907). A connecting rod (908) is fixedly connected between the two scrapers (906). The connecting rod (908) passes through the limiting groove opened in the guide plate (907). A fourth gear (905) is fixedly connected to one end of each of the multiple second lead screws (903). A half gear ring (909) is fixedly connected to the bottom of the mounting plate (9). The half gear ring (909) meshes with the multiple fourth gears (905). The lifting block (904) descends forward under the action of the limiting groove on the guide plate (907) to make it fit against the cleaning plate (902) and clean the outside of the cleaning plate (902). When the cleaning plate (902) is reset, it will move backward to ensure that the cleaning plate (902) will not contact the steel billet when it is in contact with the steel billet. After the fourth gear (905) disengages from the half gear ring (909), the lifting block (904) will return to the upper part of the cleaning plate (902) to complete one cleaning stroke, ensuring that the cleaning plate (902) in contact with the steel billet is in the best cleaning state. The first transmission assembly includes a rotating gear ring (301) rotatably connected to one side of a fixed disk (3), a first gear (302) meshing with the outer side of the rotating gear ring (301), a first motor fixedly connected to one side of the fixed disk (3), the output shaft of the first motor fixedly connected to the first gear (302), and a locking frame (7) fixedly connected to one side of the rotating gear ring (301). The second transmission assembly includes four transmission gears (401) rotatably connected to one side of the rectangular frame (4). The transmission gears (401) are connected to each other by transmission belts (402). A second motor is fixedly connected to the other side of the rectangular frame (4).

A third motor (503) is fixedly connected to the top of the support frame (501). The output shaft of the third motor (503) is fixedly connected to the first lead screw (502).

2. A forging and rolling process for processing large steel products, applicable to the forging and rolling apparatus for processing large steel products as described in claim 1, characterized in that: Includes the following steps: Step 1: Use a chamber heating furnace to heat the steel billet. The steel billet is vertically loaded into the chamber heating furnace. The chamber heating furnace adopts top heating. After heating, the steel billet is transferred to the forging and rolling equipment (2) by a ground rail car material handling machine. Step 2: Forging and rolling equipment (2) The steel billet passes through the fixed disc (3) and the rectangular frame (4). When the steel billet is cylindrical, the rack (602) is moved by the drive component and inserted into the locking frame (7) inside the fixed disc (3). The mounting frame (6) is locked to the locking frame (7) on the fixed disc (3) by the locking component. Step 3: The mounting frame (6) on the locking frame (7) is moved by the first transmission component, and the grinding part is pushed by the electric telescopic rod (8) to grind the steel billet and remove the welding slag. Step 4: When the billet is rectangular, the mounting frame (6) is locked onto the locking frame (7) on the rectangular frame (4) by the driving component, and then the grinding component is moved by the second transmission component. Step 5: Finally, the product is forged and rolled using forging and rolling equipment (2).
