Description

Technical Field

[0001] This utility model relates to the technical field of high neck flange production, and in particular to a high neck flange liquid forging forming device. Background Technology

[0002] High neck flanges refer to flanges with a higher neck height, which improves the rigidity and load-bearing capacity of the flange. Compared with welding flanges, high neck flanges require more welding work and consume more welding rods. They cannot withstand high temperature and high pressure, repeated bending and temperature fluctuations. However, they are easier to install on site and can omit the step of radiographic testing of the weld.

[0003] Liquid forging is also a commonly used forging method in the forging of high neck flanges. Currently, after the high neck flange is formed, it needs to be cooled for a period of time before the formed high neck flange can be taken out of the mold and the next high neck flange can be produced. This process wastes a lot of time, seriously affects the production efficiency of high neck flanges, and is quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a high-neck flange liquid forging forming device to solve the problems mentioned in the background art.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This utility model provides, for example Figure 1-5 The high-neck flange liquid forging forming device shown includes a worktable 1, a mounting frame 2 fixedly connected to the top of the worktable 1, and an upper mold 3 that can be vertically moved back and forth on the mounting frame 2.

[0037] Furthermore, a bearing mechanism 4 is provided at the top of the workbench 1. The bearing mechanism 4 includes: a slider 41, a bearing plate 42, a lower die 43, an ejection assembly 44, and a positioning assembly 45. The top of the workbench 1 is provided with equidistant grooves, and the slider 41 is slidably inserted into the inner cavity of the groove. The slider 41 is fixedly connected to the bearing plate 42. Multiple lower dies 43 are symmetrically fixedly connected to the top of the bearing plate 42. The ejection assembly 44 is located inside the lower die 43. The positioning assembly 45 is located inside the workbench 1 and is used to position the bearing plate 42 at multiple points. By setting multiple lower dies 43 on the bearing plate 42, after one lower die 43 has been liquid forged and cooled for a period of time, another lower die 43 can be directly replaced to the bottom of the upper die 3 to continue production. The formed high neck flange will be ejected by the ejection assembly 44. While continuing to cool, it is also convenient for subsequent workers to remove it, which speeds up the production efficiency of the high neck flange and makes it easy to use.

[0038] Specifically, the ejector assembly 44 includes: an ejector plate 441, a synchronization plate 442, a connecting rod 443, a limiting rod 444, a first compression spring 445, a pressing rod 446, and a pressing plate 447. An ejector groove is formed at the bottom end of the inner wall of the lower mold 43, and the ejector plate 441 is slidably inserted into the inner cavity of the ejector groove. A groove is formed at the bottom end of the lower mold 43, and the synchronization plate 442 is located inside the groove. One end of the connecting rod 443 is fixedly connected to the ejector plate 441, and the other end of the connecting rod 443 is fixedly connected to the synchronization plate 442. One end of the limiting rod 444 is fixedly connected to the top end of the inner wall of the groove. The other end is slidably connected to the synchronous plate 442, and the cross section of the limiting rod 444 is T-shaped; the first compression spring 445 is sleeved on the outside of the limiting rod 444, one end of the first compression spring 445 is fixedly connected to the synchronous plate 442, and the other end of the first compression spring 445 is fixedly connected to the top of the inner wall of the groove. The first compression spring 445 is always in a compressed state, so that the synchronous plate 442 can provide a stable downward elastic force to the ejector plate 441 on the connecting rod 443, so that the ejector plate 441 can be stably stored inside the ejector groove without affecting the normal production of the high neck flange. One end of the extrusion rod 446 is fixedly connected to the synchronous plate 442, and the other end of the extrusion rod 446 is slidably connected to the bearing plate 42. The extrusion plate 447 is symmetrically arranged at the top of the workbench 1. An inclined surface is opened on the opposite side of the extrusion plate 447. The extrusion plate 447 and the extrusion rod 446 cooperate with each other. Under the elastic force of the first compression spring 445, the extrusion rod 446 will be in close contact with the table surface of the workbench 1. When it slides to the position of the extrusion plate 447, the inclined surface of the extrusion plate 447 can be used to make the extrusion rod 446 rise under force, and the ejector plate 441 can eject the high neck flange after it has been formed and cooled for a period of time, which is convenient for subsequent heat dissipation and removal, and is convenient for use.

[0039] Specifically, the positioning component 45 includes: a sliding plate 451, a positioning rod 452, and a second compression spring 453. A sliding groove is provided at the top of the worktable 1. The sliding plate 451 is slidably inserted into the inner cavity of the sliding groove, and the cross-section of the sliding plate 451 is T-shaped. Multiple positioning holes are provided on the outer wall of the bearing plate 42. One end of the positioning rod 452 is fixedly connected to the sliding plate 451, and the other end is slidably inserted into the inner cavity of the positioning hole. The second compression spring 453 is located inside the sliding groove. One end of the second compression spring 453 is fixedly connected to the sliding plate 451, and the other end is fixedly connected to the inner wall of the sliding groove. The second compression spring 453 is always in a compressed state, thus providing a stable elastic force to the positioning rod 452 through the sliding plate 451. This allows the positioning rod 452 to stably insert into the positioning hole. There are two positioning holes. When the positioning rod 452 inserts into one of the positioning holes, it positions one of the lower molds 43, placing it precisely below the upper mold 3, facilitating the production of high-neck flanges.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
