Description

Technical Field

[0001] The utility model relates to the technical field of ring rolling machines, in particular to a supporting plate for a ring rolling machine. Background Art

[0002] Ring rolling machines are mainly used for the processing of ring forgings. Ring rolling machines cause continuous local plastic deformation of the rings, thereby reducing the wall thickness, expanding the diameter, and forming the cross-sectional profile. The support table of the ring rolling machine is in contact with the ring forgings to provide support for the ring forgings. The support table is very prone to wear when it is in contact with the ring forgings for a long time during the processing of the ring forgings, so it needs to be replaced frequently.

[0003] The Chinese patent with publication number CN209632038U discloses a material support table for a ring rolling machine, which relates to the technical field of ring rolling machines and aims to solve the problem that the material table of the existing ring rolling machine needs to be frequently replaced, thereby increasing the production cost. The key points of its technical solution are that the material support table includes a core roller lower support seat arranged between the driving roller and the axial tapered roller and located below the ring blank, a material support plate is arranged between the core roller lower support seat and the ring blank, and two material support plates are arranged, and the two material support plates are respectively located on both sides of the core roller; a mounting groove is arranged on the top wall of the material support plate, and a material support roller is arranged in the mounting groove along the radial direction of the ring blank, which is against the bottom end of the ring blank and can rotate circumferentially. When the driving roller drives the ring blank to rotate, the material support roller provides support force for the ring blank and can rotate with the rotation of the ring blank, avoiding the use of a material table that is easy to wear, and has the advantage of being able to effectively reduce production costs.

[0004] The above technical solution facilitates the removal and replacement or cleaning of the support plate by setting through holes and threaded holes, but the support plate is very likely to be worn due to long-term contact with the annular forging, so it is necessary to replace the support plate frequently, and the support plate is connected to the lower support seat of the core roller by bolts. The bolt connection method is inconvenient to disassemble and install, and the removal and replacement of the support plate is inconvenient, and the disassembly efficiency is low. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a support plate for a ring rolling machine. The support plate body can be directly fixed by aligning the lower mounting plate with the slide groove. During disassembly, the moving rod is moved downward to make the limit rod clamped in the limit frame. The upper mounting plate squeezes the slide block so that the entire slide block is located inside the open groove. The support plate body can be directly lifted up to be replaced, making the disassembly of the support plate body more convenient.

[0006] The technical solution to achieve the purpose of the utility model is: a ring rolling machine support plate, including a support frame, the top wall of the support frame is provided with a support plate body, and also includes;

[0007] Multiple mounting components, multiple mounting components are arranged on the bottom end wall surface of the support plate body, the mounting components include a sleeve, the sleeve is fixedly mounted on the bottom end wall surface of the support plate body, a lower mounting plate is fixedly mounted on the bottom end of the side wall of the sleeve, the side wall of the sleeve is provided with two slots, a moving rod is slidably mounted on the inner side wall of the sleeve, a fixed rod is fixedly mounted on the side wall of the moving rod, an upper mounting plate is fixedly mounted on the side wall of the fixed rod, a limiting rod is fixedly mounted on the side wall of the moving rod, a limiting frame is fixedly mounted on the top wall surface of the support plate body, a limiting groove is provided on the top wall surface of the limiting frame, a plurality of sliding grooves are provided on the top wall surface of the support frame, open grooves are provided on both side wall surfaces of the inner part of the sliding groove, a second spring is fixedly mounted on the inner side wall of the open groove, and a slider is fixedly mounted on the other end of the second spring.

[0008] In some embodiments, a plurality of grooves are formed on the top wall of the supporting plate body, and rollers are rotatably mounted on the inner side walls of the grooves.

[0009] In some embodiments, a first spring is fixedly mounted on the inner bottom end wall of the sleeve, and the moving rod and the inner bottom end wall of the sleeve are connected via the first spring.

[0010] In some embodiments, the cross section of the lower mounting plate is in the shape of an inverted truncated cone, and the upper mounting plate and the lower mounting plate are distributed in a mirror-symmetrical manner.

[0011] In some embodiments, a limit plate is fixedly mounted on the side wall of the two sliders that are away from each other, and the side wall of the two sliders that are close to each other is inclined.

[0012] In some embodiments, a collar is fixedly mounted on the top wall of the moving rod.

[0013] Compared with the prior art, the utility model has the following significant advantages:

[0014] When the support plate is moved to the bottom of the slide, the slide is subjected to the reaction force of the second spring to move the slide in the original direction, resetting the slide so that the slide fixes the lower mounting plate, thereby fixing the support plate body. When disassembly is required, the moving rod is driven downward to make the limit rod pass through the limit groove. During the downward movement, the bottom wall surface of the upper mounting plate squeezes the inclined surface of the slide, and then the moving rod is rotated, and the limit rod rotates to the inside of the limit frame to fix the moving rod.

The setting of the first spring 5 facilitates the resetting of the moving rod 4. The first spring 5 is fixedly installed on the bottom wall. The other end of the first spring 5 is fixedly connected to the moving rod 4. The moving rod 4 penetrates the sleeve 3 and extends to the top wall of the supporting plate body 2. The side wall of the moving rod 4 is fixedly installed with a fixing rod 41. The fixing rod 41 penetrates the two card slots 31 and is slidably installed on the inner side walls of the two card slots 31. The side wall of the fixing rod 41 is fixedly installed with an upper mounting The upper mounting plate 42 is distributed in a mirror-symmetrical manner with the lower mounting plate 32.
