Description

Technical Field

[0001] The present invention relates to the technical field of bearing ring production, in particular to a forging device for bearing ring production. Background Art

[0002] Bearing rings are the core components of bearings, usually referring to the inner and outer rings of bearings. Together with rolling elements (such as balls and rollers), they constitute the basic structure of the bearing and undertake key functions such as supporting the rotating shaft, reducing friction, and transmitting loads. Forging devices are key equipment in the production of bearing rings. They increase material density and improve the organizational structure through plastic deformation, thereby enhancing the mechanical properties of the bearing rings.

[0003] Prior art 1 (Chinese patent with announcement number CN110369659B and announcement date of 2020-10-13) is a bearing forging equipment, whose structure includes: a forging seat, a hydraulic pipe, an air hammer, a hydraulic device, a lubrication bin, a pressure seat, a power frame, and a base. The height change of the extension frame can be extended upward along the slider during lifting to form a protective cover similar to a cone-shaped structure. When the air hammer falls, it can not only form a cone-shaped structure to surround the bearing ring blank to prevent the workpiece from flying to the side, but also the structure on the balance guard frame has the effect of multiple shock absorption, which can play a role in progressively weakening the vibration force layer by layer until it is eliminated. The two completely different shock absorption structures of bounce shock absorption and dispersion shock absorption can achieve all-round shock absorption for the balance guard frame, reducing the high-intensity impact generated by the edge of the workpiece being hit from the side to cause it to fly. The protective cover-shaped structure can block and reset the workpiece while it flies up. There is also prior art 2 (Announcement No. CN115055630A, Announcement Date 2022-09-16 Chinese Patent) A forging device for forging parts, comprising: a forging base, the middle part of which is horizontally arranged on the forging table, and the forming mold is arranged on the forging table; a forging power part, which is fixedly arranged above the forging base and is used to provide power for forging; a forging plate, which is movably arranged above the forming mold, and the forging plate is pressed toward the forming mold under the action of the forging power part; a sliding sleeve assembly, which is fixedly arranged on the forging base and guides the downward pressing path of the forging plate. It does not require a lot of time to position the mold, which can greatly improve production efficiency, and has good stability after forging, and the production precision of forged parts is high.

[0004] Although existing technologies can significantly improve production efficiency, they will produce impurities such as metal oxide scale and scraps that fall or splash from the hammer during forging. If these impurities are not cleaned in time, they may be pressed into the forgings, forming surface pits or internal slag inclusions, thereby affecting the quality of the forgings, the life of the mold and even safe production.

[0005] Therefore, we propose a forging device for bearing ring production in order to solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: the swing plate swings back and forth around the fixed axis under the action of the driving mechanism, and the blow box driven by the linked air supply mechanism realizes dynamic cleaning of the entire work surface, eliminating the interference of waste chips on the forging operation; during the lifting process of the lifting module, the fixed rod drives the push plug to slide, and the left and right fixed cylinders alternately supply air, so that the blow box can be continuously cleaned over a large area during the entire forging process, avoiding impurities from being pressed into the forgings and ensuring the quality of the forgings; the swing plate swings around the fixed axis to realize multi-angle dynamic adjustment of the blow box and improve the cleaning coverage rate; the second magnetic block drives the fixed plate to slide under the action of the magnetic field repulsion, and the resistance rod resists the lifting block to realize vertical lifting of the bearing ring forging, preventing forging sticking: (1) A swing plate is provided on the side of the work surface. The swing plate swings back and forth around a fixed axis under the action of a driving mechanism. After the air supply mechanism connected to the outer end of the blow box is started synchronously, the swing plate drives the blow box to swing in conjunction, realizing full-range dynamic cleaning of the work surface, effectively preventing waste chips from interfering with subsequent forging operations.

[0017] (2) Whether the lifting module is in the process of rising or falling, the fixed rod can drive the push plug to slide along the inner wall of the fixed cylinder. When the lifting module is displaced, the fixed cylinders on the left and right sides supply air alternately, so that the blow box can achieve large-scale dust cleaning during and after forging. This design significantly improves the cleaning effect of the forging operation, effectively avoids impurities from remaining or being pressed into the forging, thereby ensuring the quality of the forging.

[0018] (3) When the push plug moves back and forth, it squeezes the gas in the fixed cylinder, and the gas is transported to the receiving cylinder through the connecting air pipe. The gas pressure drives the built-in fan to rotate, which in turn drives the coaxial shaft to rotate. The turntable fixed on the upper end of the shaft rotates synchronously, causing the friction shaft to slide back and forth along the slide groove of the swing plate. During the sliding process, the friction shaft continuously applies force to the swing plate, driving it to swing around the fixed axis, and finally realizing multi-angle dynamic adjustment of the blow box.

[0019] (4) When the lifting module drives the fixed rod to slide, it simultaneously drives the external fixed electrical contact piece to move horizontally into the electrical contact ring. After the two are in contact and connected, power is supplied to the electromagnetic block to magnetize it, and then the adjustment mechanism is driven to lift the bearing ring, effectively preventing the bearing ring from sticking to the work surface.

[0020] (5) After the electromagnetic block is energized, the second magnetic block drives the fixed plate to slide in a limited direction away from the electromagnetic block under the action of the magnetic field repulsion. During the sliding process of the fixed plate, the resistance rod slides along the movable groove and applies a vertical upward force to the lifting block. After the lifting block is pressed, it is lifted upward along the work surface, realizing the reliable separation of the bearing ring and the work surface, and effectively preventing forging and pressing from sticking.
