Abstract
Description
Technical Field
[0001] This utility model belongs to the field of forging tooling processing technology, and specifically relates to a forging hole expansion support frame. Background Technology
[0002] Forging is a processing method that uses forging machinery to apply pressure to a metal billet, causing it to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and dimensions.
[0003] Existing methods for forging ring-shaped workpieces include three stages: upsetting, punching, and reaming. This method involves placing the punched cylindrical blank onto a reaming rod, which is then placed on a frame on the hammer anvil before the reaming operation can proceed. However, because the frame is placed directly on the hammer anvil, it is prone to movement and displacement when the hammer strikes the workpiece on the reaming rod. This movement affects the reaming efficiency, requiring repeated hammer operations and constant adjustments by the operator, thus increasing the operator's workload and prolonging the forging time. Summary of the Invention
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a forging hole enlargement support frame with a simple structure that enables the support frame to be installed more stably on the hammer anvil, thereby improving work efficiency.
[0005] The technical solution for the purpose of this utility model is:
[0006] A forging hole enlargement support frame includes a frame and a lever. The frame has grooves on its two support blocks for placing the lever. The lower end face of the frame has downwardly bent support feet for mounting on a hammer anvil. Both support blocks of the frame have outwardly extending support rods.
[0007] Furthermore, the groove is an arc-shaped groove.
[0008] Furthermore, the support foot is an arc-shaped support foot.
[0009] Furthermore, the horse frame has a U-shaped structure.
[0010] Furthermore, the lower end face of the horse frame is provided with four downward-bending support legs.
[0011] Furthermore, it also includes a counterweight, which is sleeved on the support rod.
[0012] The above technical solution has the following beneficial effects:
[0013] This invention features a simple structure. A support frame on the lower end of the frame is mounted on the anvil, securing the frame firmly and preventing movement during the reaming process. Both support blocks of the frame have outwardly extending support rods. These support rods, distributed on both sides of the frame, not only facilitate the placement of the punching workpiece to be reamed and allow for quick workpiece loading and unloading, but also allow for the placement of counterweights and the pressing of the support rods, thus stabilizing the frame. In short, this invention achieves a more stable fixation of the frame to the anvil and improves work efficiency.
[0014] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description
[0015] Figure 1 This is a schematic diagram of the structure of specific embodiment 1.
[0016] In the attached diagram, 1 is the frame, 2 is the support leg, 3 is the support rod, and 4 is the groove. Detailed Implementation
[0017] See Figure 1 As shown, a forging hole-expanding support frame includes a frame 1 and a support bar. The frame is U-shaped, and the two support blocks of the frame 1 have grooves 4, which are arc-shaped grooves. The grooves are used to place the support bar, and the workpiece to be expanded is placed on the support bar between the two support blocks. The lower end face of the frame 1 has downwardly bent support legs 2, which are arc-shaped and match the shape of the upper end face of the hammer anvil. The support legs 2 are used to support the frame on the hammer anvil, allowing the frame to be installed more stably and firmly on the hammer anvil. In this specific embodiment, the lower end face of the frame 1 has four downwardly bent support legs 2. Compared with existing frames that are placed directly on the hammer anvil without a support frame, this utility model makes the frame more stable.
[0018] The frame 1 has outwardly extending support rods 3 on both support blocks, ensuring even force distribution on both sides of the support blocks. These support rods 3 not only place the workpiece to be enlarged, facilitating quick workpiece placement and removal, but also increase the weight of the frame, improving its stability. Furthermore, pressing down on the frame with the support rods further enhances its stability, preventing it from bouncing and improving work efficiency.
[0019] It may also include a counterweight, which is fitted onto the support rod to increase the weight of the frame, prevent the frame from jumping during hammering, and improve work efficiency and processing accuracy.
