Description

Technical Field

[0001] The utility model belongs to the technical field of forging, and in particular relates to a hammer forging device for sleeve forging. Background Art

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause them to undergo plastic deformation in order to obtain forgings with certain mechanical properties, shapes and sizes. Forging and stamping are two major components. Forging can eliminate defects such as loose cast metal produced during the smelting process, optimize the microstructure, and because the complete metal flow lines are preserved, the mechanical properties of forgings are generally better than those of castings of the same material. The general forging method is to use a handheld fixture to flip the forging and continuously hammer it into shape on a hammering machine. However, this method is not only extremely wasteful of labor costs, the forged workpiece cannot be stable and consistent, and it also requires a high level of technical skills from the operator.

[0003] In the prior art, the patent document with the announcement number CN 216027821 U discloses a hammering device for composite forging of a left steering arm, in which a front baffle cover is arranged in front of the forging hammering device base, a front end face of the forging hammering device base is provided with a reserved mounting hole groove, and the reserved mounting hole groove is integrally built with the forging hammering device base, one end of the front baffle cover is installed inside the reserved mounting hole groove, an observation window is arranged above the inside of the front baffle cover, and the observation window is integrally built with the front baffle cover, and a door panel is arranged below the observation window, the door panel is rotatably connected to the front baffle cover through a rotating shaft body, and two rotating shaft bodies are provided, and a handle bar is arranged on the front end face of the door panel, and the handle bar is fixedly connected to the door panel. The above scheme solves the problem of injuries caused by splashing of high-temperature materials, but does not solve the problem of stable and consistent size, shape and performance of forged workpieces and labor costs.

Other shapes are also acceptable, but the moment bearing is prone to imbalance and instability. The hydraulic cylinder mechanism 2 has a piston rod that moves back and forth in the vertical direction, and a counterweight hammer installation upsetting 3 is installed at the bottom of the piston rod. A forging hammer punch structure 4 is detachably installed on the lower surface of the counterweight hammer installation upsetting 3, and a forging pedestal 5 is provided below the forging hammer punch structure 4, and a forging die structure 6 is detachably installed in the middle of the forging pedestal 5.

[0025] An installation cavity 51 is provided in the middle of the forging pedestal 5 , a boss structure 52 is provided in the middle of the bottom wall of the installation cavity 51 , and a mold installation telescopic frame 7 is provided on the top of the forging pedestal 5 for installing the forging mold structure 6 .

[0026] The above-mentioned mold installation telescopic frame 7 includes a mounting ring structure 71 and a telescopic connection mechanism 72. The telescopic connection mechanism 72 is arranged in the forging pedestal 5, wherein the telescopic connection mechanism 72 is a hydraulic cylinder or an adjusting threaded rod. The adjusting threaded rod is more stable by rotation adjustment, but the operation is inconvenient, while the hydraulic cylinder is the opposite. The mounting ring structure 71 is installed on the top of the forging pedestal 5 through the telescopic connection mechanism 72, and the mounting ring structure 71 is arranged around the edge of the mounting cavity 51. The inner ring of the mounting ring structure 71 is evenly surrounded by mounting threaded holes 73 for mounting the forging mold structure 6 through a bolt structure.

[0027] T-slot structures 31 are evenly opened on the lower surface of the counterweight hammering mounting upsetting 3, and the forging hammering punch structure 4 has a hammering punch 41 and a mounting plate frame 42. The hammering punch 41 is arranged in the center of the mounting plate frame 42, and the hammering punch 41 is arranged downward. A plurality of mounting holes are provided on the mounting plate frame 42, and the mounting holes are evenly distributed around the hammering punch 41. A bolt structure is installed in the mounting hole, and the bolt structure cooperates with the T-slot structure 31. The forging hammering punch structure 4 cooperates with the T-slot structure 31 through the bolt structure, so that it is stably and detachably installed on the lower surface of the counterweight hammering mounting upsetting 3.

[0028] The principle is as follows: the counterweight hammering installation upsetting 3 is driven by the hydraulic cylinder mechanism 2 to move up and down in the vertical direction, so that the forging hammering punch structure 4 continuously hammers the forging in the forging die structure 6. The gravity of the counterweight hammering installation upsetting 3 makes the hammering effect more stable when it falls, avoiding the punch rigid bouncing, which makes the forging effect poor, and cooperates with the forging die structure 6 to form, so the size, shape and performance of the forged workpiece are stable and consistent, saving labor costs; and the bottom of the forging die structure 6 is also movably matched with a boss structure 52, so that the chain segments can be ventilated, avoiding Excessive sealing causes air holes to form during the forging process, wherein the forging die structure 6 is movably mounted on the die mounting telescopic frame 7. When the forging die structure 6 is moved downward by the die mounting telescopic frame 7, the forging is ejected by the bottom boss structure 52, thereby facilitating demolding. At the same time, the forging base 5 with the mounting cavity 51 ensures the stability of the installation of the forging die structure 6, avoids sparks, and maintains temperature stability. The forging die structure 6 and the forging hammer punch structure 4 are detachable and replaceable, so they can adapt to the manufacture of different forgings and have strong applicability.
