Description

Technical Field

[0001] The utility model relates to the technical field of forging equipment, and particularly relates to a forging automatic blanking device. Background Art

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing plastic deformation to obtain forgings with certain mechanical properties, certain shapes and dimensions. It is one of the two major components of forging and pressing (forging and stamping). Through forging, defects such as as-cast porosity generated during the smelting process of metals can be eliminated, and the microstructural organization can be optimized. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings made of the same material. For important parts with high loads and severe working conditions in related machinery, except for those with relatively simple shapes that can use rolled plates, profiles or welded parts, forgings are mostly used.

[0003] Publication (Announcement) Number: CN216705821, which discloses a forging automatic blanking device. After the workpiece is completed, the automatic blanking device and the processing punch move upward. Driven by the machine, two closed moving sliders and the main blanking rod separate the two moving sliders, and the finished workpiece is ejected. Then, through the spring, the automatic reset of the moving slider is realized, achieving automation. The structure of this automatic blanking device is reasonably designed, convenient to use, and has high practicability.

[0004] In the above patent, although the blanking function can be realized, there is no buffering effect during the stamping process, it is difficult to ensure the integrity of the object during forging, and the blanking is a single-rod ejection, which cannot ensure the perfect ejection of the object. Therefore, it is necessary to provide a forging automatic blanking device. Summary of the Utility Model

[0011] Preferably, the lifting unit further includes a stamping hole penetratingly opened at the center of the bottom of the mounting frame, fixed sliding plates fixedly connected to both sides of the mounting frame, through holes penetratingly opened at the top of one end of the fixed sliding plates, and a fixed rod fixedly connected between the upper and lower walls of the sliding grooves.

[0012] Preferably, the ejection unit further includes a spring groove opened at the top of the ejection rod, an abutting column movably arranged inside the spring groove, a limiting plate fixedly connected to the bottom end of the abutting column, and a return spring fixedly connected to the bottom of the limiting plate.

[0013] Preferably, the forging machine is installed inside the mounting frame, the end width of the fixed sliding plate is adapted to the inner width of the sliding groove, and the outer diameter dimension of the through hole is adapted to the outer diameter dimension of the fixed rod.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] In the present utility model, the mold is placed inside the mold placement groove, and the mold contacts the tops of the two abutting columns. Then, the hydraulic cylinder is started to push the mounting frame to descend. Among them, the fixed sliding plates arranged on both sides of the mounting frame slide and are limited by the outer surface of the fixed rod inside the sliding groove to provide stability. The descent of the mounting frame drives the forging machine installed inside it to descend. After descending to a suitable position, the forging machine is started so that the stamping head at its bottom passes through the stamping hole to perform forging operations on the forging. This structure can stably lift and lower the forging machine, improves the stability of the forging machine during forging operations, ensures the forging quality of the forging, and has good practicability.

[0017] Second, in the present utility model, by placing the mold inside the mold placement groove, and the mold being in contact with the tops of two abutting columns, and under the action of the limiting plate and the return spring, the buffering effect on the mold is achieved. And when the forging machine descends, the U-shaped rod descends inside the rod hole, and the descent of the U-shaped rod drives the two ejection rods to descend inside the mold placement groove, so that the abutting columns follow and descend, and drive the mold to descend and be limited inside the mold placement groove. Then start the forging machine to make the stamping head descend to perform forging operation on the object. After forging is completed, as the mounting frame ascends, the U-shaped rod is driven to ascend by the fixed slide plate, thereby driving the two ejection rods to ascend to eject the mold and the forged object, thus completing the ejection operation. This structure can realize the function of automatically ejecting and discharging the object after forging, and has the buffering effect during forging, ensuring the integrity of the forging, facilitating the discharging quickly, and improving the forging efficiency and quality.
