Description

Technical Field

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

[0002] Ring rolling machines are divided into vertical and horizontal types according to the form of the frame and the position of the ring parts. Most small and medium-sized ring rolling machines adopt inclined vertical type for the convenience of operation. However, the lower end support of the current vertical ring rolling machines is mostly a fixed structure, which cannot be fine-tuned according to the ring rolling process, resulting in low ring rolling processing efficiency.

[0003] A Chinese patent with publication number CN210412370U was searched and disclosed, which discloses a vertical ring rolling machine for forging processing. It can realize multi-angle support of the forging ring and improve the processing accuracy. At the same time, it can fine-tune the support of the forging after ring deformation during the ring rolling process, which can prevent the ring deformation of the forging and improve the product quality.

[0004] Based on the above search and combined with the prior art, it is found that the above patent has certain defects. When the forging ring is rolled, multi-angle support is provided by the bottom support structure, but the outside of the forging ring is not limited. During the support and rolling process, part of it is easy to warp outward, the structure is no longer flat, and the structure is not convenient for unloading, which reduces the use efficiency of the vertical ring rolling machine. Utility Model Content

[0005] The utility model aims to provide a vertical ring rolling machine for forging processing to solve the problems raised in the above-mentioned background technology.

[0006] The technical scheme of the utility model is: a vertical ring rolling machine for forging processing, comprising a forging ring and a mounting frame, wherein electric push rods are installed on both side outer walls of one side of the top of the mounting frame, one end of the electric push rod piston rod is fixedly connected to a fixing block, rectangular grooves are opened on both side outer walls of one side of the mounting frame, and a support plate is fixedly connected to the outer wall of one side of the rectangular groove, and the outer wall of the support plate is slidably connected to a U-shaped frame, the inner walls of both side walls of one side of the U-shaped frame are slidably connected to a limiting frame 2, the inner walls of both side walls of the other side of the U-shaped frame are fixedly connected to a limiting frame 1, mounting holes are opened on both side outer walls of one side of the U-shaped frame, the inner walls of the mounting holes are fixedly connected to a telescopic rod, one end of the telescopic rod piston rod is respectively fixedly connected to the outer walls of both sides of the limiting frame 2, and a reset spring is sleeved on the outer wall of one end of the telescopic rod piston rod, and the reset spring is connected to the limiting frame 2 and the telescopic rod.

[0007] Preferably, the first limiting frame is adapted to the size of the rectangular groove, and the first limiting frame and the second limiting frame are adapted to the size of the forging ring.

[0008] Preferably, both outer walls on the other side of the U-shaped frame are provided with sliding grooves, and the support plates are slidably connected to the inner walls of the sliding grooves.

[0009] Preferably, both side outer walls of one side of the bottom of the mounting frame are fixedly connected with a fixing bracket, and the top outer wall of the fixing bracket is installed with an adjusting cylinder.

[0010] Preferably, one end of the adjusting cylinder piston rod is fixedly connected to a support block, the support block is located directly below the forging ring, and the support block is slidably connected to the outer walls on both sides of the bottom end of the forging ring.

[0011] Preferably, an outer wall on one side of the limiting frame 1 and an outer wall on the other side of the limiting frame 2 are both provided with mounting grooves, and rollers are installed on the inner walls of the mounting grooves, and the rollers are rollingly connected to the outer wall of the forging ring.

[0012] The utility model provides a vertical ring rolling machine for forging processing through improvement, which has the following improvements and advantages compared with the prior art:

[0013] First, the utility model is provided with a mounting frame, an electric push rod, a U-shaped frame, a support plate, a telescopic rod and a reset spring to maintain the flatness of the overall structure of the forging ring. When the width becomes wider, the second limit frame contracts under the action of the telescopic rod and the reset spring. After the rolling is completed, the electric push rod acts to push the U-shaped frame outward, and the U-shaped frame slides on the support plate of the mounting frame. At the same time, the limit frame in the rectangular groove of the mounting frame also pushes out the rolled forging ring. When the forging ring is completely separated from the support block and the rolling structure, it directly falls under the action of gravity to complete the unloading, which solves the problem that the outer part of the forging ring is not limited, and the part is easy to be tilted outward during the support and rolling process, and the structure is no longer flat. It is more convenient to unload the forging ring after rolling, and the use efficiency of the vertical ring rolling machine is improved;

[0014] Secondly, the utility model provides a limiting frame 1, a limiting frame 2 and a roller, and the inner walls of the limiting frame 1 and the limiting frame 2 are both installed with rollers. When limiting the forging ring, the friction force is reduced by rolling, the wear of the forging ring is reduced, and the practicality of the vertical ring rolling machine is improved.

[0025] Furthermore, the limit frame 1 8 is adapted to the size of the rectangular groove 13, the limit frame 1 8 and the limit frame 2 10 are adapted to the size of the forging ring 1, and the outer walls on both sides of the other side of the U-shaped frame 3 are provided with sliding grooves 14, and the support plates 12 are slidably connected to the inner walls of the sliding grooves 14.

[0026] Furthermore, the outer walls on both sides of the bottom side of the mounting frame 2 are fixedly connected with fixed brackets 16, the outer walls on the top ends of the fixed brackets 16 are installed with adjusting cylinders 5, one end of the piston rod of the adjusting cylinder 5 is fixedly connected with support blocks 6, the support blocks 6 are located directly below the forging ring 1, the support blocks 6 are slidably connected to the outer walls on both sides of the bottom end of the forging ring 1, one outer wall of one side of the limit frame 1 8 and the other outer wall of the limit frame 2 10 are respectively provided with mounting grooves, the inner walls of the mounting grooves are installed with rollers 9, the rollers 9 are rollingly connected to the outer wall of the forging ring 1, the inner walls of the limit frame 1 8 and the limit frame 2 10 are installed with rollers 9, the friction is reduced by rolling when the forging ring 1 is limited, and the wear of the forging ring 1 is reduced.

[0027] Working principle: When in use, the mounting frame 2 is fixedly installed on the outer wall of one side of the vertical ring rolling machine for rolling the forging ring 1, and the forging ring 1 to be rolled is placed on the rolling structure of the vertical ring rolling machine. At this time, the U-shaped frame 3 and the mounting frame 2 are close to each other, and the forging ring 1 is limited by the limiting frame 1 8 and the mounting frame 2 on the inner side, and is limited by the limiting frame 2 10 and the telescopic rod 7 on the outer side. The support block 6 on the adjustment cylinder 5 is supported on the outer wall of the bottom end of the forging ring 1. When rolling, the forging ring 1 continues to grow larger and wider, and the forging ring 1 rotates when being rolled. The outer side is limited by the limiting frame 2 10 to keep it stable. The limiting frame 2 10 is always restrained to prevent part protrusion, so as to keep the forging ring 1 stable. The overall structure of the forging ring 1 is flat. When it becomes wider, the limiting frame 10 shrinks under the action of the telescopic rod 7 and the reset spring 15. After the rolling is completed, the electric push rod 11 acts to push the U-shaped frame 3 outward, and the U-shaped frame 3 slides on the support plate 12 of the mounting frame 2. At the same time, the limiting frame 1 8 in the rectangular groove 13 on the mounting frame 2 will also push out the rolled forging ring 1. When the forging ring 1 is completely separated from the support block 6 and the rolling structure, it falls directly under the action of gravity to complete the unloading. The inner walls of the limiting frame 1 8 and the limiting frame 2 10 are both installed with rollers 9. When the forging ring 1 is limited, the friction is reduced by rolling, thereby reducing the wear of the forging ring 1.
