Description

Technical Field

[0001] This invention relates to the field of billet forging technology, and in particular to a billet forging apparatus for automobile parts production. Background Technology

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and dimensions. Forging can eliminate defects such as casting porosity generated during the smelting process, optimize the microstructure, and because it preserves complete metal flow lines, the mechanical properties of forgings are generally superior to those of castings made of the same material.

[0003] During forging, scale falls off the high-temperature steel billet. To avoid affecting subsequent forging, the scale is often scraped off manually using a scraper. Manual scraping not only increases labor intensity but also poses safety hazards due to the worker's proximity to the forging press. Furthermore, it is difficult to clean the scale adhering to the bottom surface of the forging plate manually, and there is no way to effectively collect and process the scale. The scraped-off scale also needs to be cleaned separately later, which is not convenient for recycling. Summary of the Invention

Example

[0021] Reference Figures 1-8 This is the first embodiment of the present invention, which provides a steel billet forging device for automobile parts production, including a forging table 1, used as a forging table; a forging plate 2 is installed above the forging table 1, used as a forging plate, and an electro-hydraulic rod is connected to the upper end of the forging plate 2 to provide power for forging; the forging table 1 and the forging plate 2 are supported on the ground by a bracket; a fan 5 is installed on one side of the bottom surface of the forging table 1, and the fan 5 provides airflow on one side; a forging plate cleaning mechanism 3 is used to scrape off the oxide scale adsorbed on the forging surface of the forging plate 2; a scraper 32 is provided in the forging plate cleaning mechanism 3, which slides along the slide rail 31, and the scraper 32 adheres to the bottom surface of the forging plate 2 during the movement; A forging table cleaning mechanism 4 is installed on one side of the forging table 1. The forging table cleaning mechanism 4 is used to clean the oxide scale on the forging table 1. The forging table cleaning mechanism 4 includes several pressure strips 41. The pressure strips 41 deflect only during the rising of the forging plate 2. The pressure strips 41 are embedded in the corresponding cleaning port 11 on the forging table 1 to clean the oxide scale retained on the forging table 1. The bottom surface of the forging table 1 is provided with a flattening mechanism 6, which can cooperate with the forging table 1 to make the upper surface of the forging table 1 flat.

[0022] The forging plate surface cleaning mechanism 3 includes two slide rails 31 located on both sides of the forging plate surface 2. The slide rails 31 are fixed to the forging plate surface 2 by a first connecting block 39. The slide rails 31 are hollow inside, one end of the slide rails 31 is arc-shaped, a first storage mechanism 36 is installed at the arc end of the slide rails 31, and a second storage mechanism 37 is installed at the other end. The scraper 32 is slidably embedded into the slide rail 31 at both ends through the sliding head 33. At least one sliding head 33 is connected to the two sides of the connecting rope 35, and the other ends of the two connecting ropes 35 are respectively connected to the first storage mechanism 36 and the second storage mechanism 37. A first rack 38 is installed on one side of the second storage mechanism 37, and a second gear 373 inside the second storage mechanism 37 meshes with the first rack 38.

[0023] Preferably, when the first storage mechanism 36 moves downward along with the forging plate 2, the first storage mechanism 36 will not interfere with the pressure bar 41.

[0024] Preferably, as the forging plate 2 moves downward, the scraper 32 moves from the parallel end of the slide rail 31 to the arc-shaped end at a speed faster than the downward movement speed of the forging plate 2, so that the scraper 32 will not interfere with the workpiece to be forged.

[0025] The forging table cleaning mechanism 4 includes several linearly arrayed pressure bars 41; One side of each pressure bar 41 is connected to a connecting plate 45, and both ends of the connecting plate 45 are connected to the upper ends of rocker arms 46. The lower ends of both rocker arms 46 are movably connected to the connecting frame 42. A return mechanism 44 is installed on one side of one of the rocker arms 46. The lower end of one of the rocker arms 46 is connected to a one-way damping bearing 48 through a movable shaft. A first gear 47 is installed on the other side of the one-way damping bearing 48. The first gear 47 meshes with a second rack 43. The upper end of the second rack 43 is connected to the forging plate surface 2.

[0026] Preferably, before forging, the rack on the second rack 43 is at a certain distance from the first gear 47.

[0027] The first storage mechanism 36 includes a coil spring 362, which is connected to the slide rail 31. The coil spring 362 has a first storage shell 361 installed inside. A shaft is installed in the middle of the first storage shell 361. A first storage roller 363 is installed on one side of the shaft. One end of the connecting rope 35 is connected inside the first storage roller 363. The connecting rope 35 passes through the slide rail 31 and the coil spring 362.

[0028] The second storage mechanism 37 includes a second storage shell 371; a second storage roller 372 is installed inside the second storage shell 371, one end of the second storage roller 372 is connected to a second gear 373, the other side of the second gear 373 is connected to a second connecting block 375 through a connecting column 374, and the second connecting block 375 is connected to the forging plate surface 2.

[0029] The return mechanism 44 includes an arc-shaped groove 441, which is installed on the forging table 1. The interior of the arc-shaped groove 441 is hollow and semi-enclosed. An arc-shaped slide bar 442 is slidably provided inside the arc-shaped groove 441. One end of the arc-shaped slide bar 442 is fixed to the rocker arm 46. The other end of the arc-shaped slide bar 442 is connected to a spring 443. The other end of the spring 443 is connected to the interior of the arc-shaped groove 441.

[0030] Preferably, the forging plate 2 moves downward, and the second rack 43 meshes with the first gear 47; the first gear 47 rotates freely under the action of the one-way damping bearing 48, without causing the rocker arm 46 to deflect; after forging is completed, the leveling mechanism 6 moves downward, the forging plate 2 moves upward, the first gear 47 causes the rocker arm 46 to deflect, and the pressure bar 41 removes the oxide scale on the forging table 1 from the cleaning port 11.

[0031] The forging table 1 is provided with a number of cleaning ports 11 arranged in a linear array. The cleaning ports 11 are provided with receiving grooves 12 on both sides, which can accommodate the slide rail 31.

[0032] The leveling mechanism 6 includes several linearly arranged leveling protrusions 61, with a base plate 62 installed on the bottom surface of the leveling protrusions 61, and an electric telescopic rod 63 installed on the bottom surface of the base plate 62. The cross section of the flat protrusion 61 is consistent with the cross section of the cleaning port 11; the flat protrusion 61 can be embedded in the cleaning port 11.

[0033] During use, the forging plate 2 moves downward, and the scraper 32 quickly slides from one end of the slide rail 31 to the other end, with the final position of the scraper 32 higher than the bottom surface of the forging plate 2. After forging is completed, the forging plate 2 moves upward, and the leveling mechanism 6 moves downward, freeing up the bottom surface of the cleaning port 11. The forging table cleaning mechanism 4 deflects, and the pressure bar 41 performs a cleaning operation of the oxide scale. At the same time, the scraper 32 slides in the opposite direction to complete a scraping operation of the oxide scale on the bottom surface of the forging plate 2. The oxide scale falls onto the bottom plate 62 and is finally blown to one side by the fan 5 for concentrated cleaning of the oxide scale.

[0034] In summary, the device utilizes the forging plate surface cleaning mechanism 3 and the forging table surface cleaning mechanism 4 to clean the oxide scale on the table surface and the bottom surface of the forging plate, respectively. This cleaning is performed after each forging operation, ensuring that the oxide scale does not affect subsequent forging of the steel billet. Without interfering with the existing forging process, the device triggers the forging plate surface cleaning mechanism 3 and the forging table surface cleaning mechanism 4 through the forging plate surface 2 to perform a cleaning operation after each forging operation. The device effectively removes accumulated oxide scale, and the leveling mechanism 6 performs centralized cleaning of the oxide scale.
