Description

Technical Field

[0001] This utility model relates to the field of ring rolling machine technology, and in particular to a ring rolling machine core roller lifting device. Background Technology

[0002] Ring rolling is a plastic processing technology that uses a ring rolling mill to induce continuous localized plastic deformation in a ring, thereby reducing wall thickness, increasing diameter, and shaping cross-sectional contours. Therefore, ring rolling mills are suitable for producing ring-shaped mechanical parts of various shapes and sizes, such as bearing rings, gear rings, flanges, wheel hubs, and other seamless ring forgings. They are widely used in many industrial fields such as machinery, automobiles, trains, and wind power generation. The core roller lifting device of the ring rolling mill is the core mechanism responsible for adjusting the position of the core roller in the ring rolling mill (a key piece of equipment used for rolling ring parts). Its main function is to achieve precise lifting, positioning, and stable support of the core roller to meet the rolling requirements of rings of different sizes.

[0003] An existing ring rolling mill core roller lifting device (publication number: CN206676920U) has at least the following drawbacks:

[0004] In the aforementioned patent, the core roller can move up and down by pushing the first slider with a hydraulic cylinder, and the core roller can move left and right quickly by pushing the second slider with a lead screw. The adjustment is flexible and improves production efficiency. However, when producing ring blanks, the ring blanks will generate smoke and heat radiation, which will pollute the surrounding air and increase the air temperature. At the same time, the rotating ring blanks will throw out debris that falls to the bottom and needs to be cleaned manually, which is quite troublesome. Therefore, there is an urgent need for a core roller lifting device for ring rolling machines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a ring rolling mill core roller lifting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ring rolling mill core roller lifting device includes: a ring rolling mill body, a ring blank movably sleeved on the outer circular wall of the support roller of the ring rolling mill body, a PLC controller fixedly installed on one side of the ring rolling mill body, and a dust suction assembly for sucking away the generated smoke and dust. The dust suction assembly is disposed on one side of the ring rolling mill body, and the dust suction assembly includes: a dust suction hood, the dust suction hood is fixedly installed on one side of the core roller lifting platform of the ring rolling mill body, an air suction pipe is connected to the top surface of the dust suction hood, the core roller of the ring rolling mill body is disposed inside the dust suction hood, and a collection mechanism is provided on one side of the ring rolling mill body for collecting the debris thrown out during the ring rolling process.

[0008] As a further embodiment of this utility model, the collecting mechanism includes: a support frame, which is fixedly installed on one side of the ring rolling mill body. Two first circular through holes are opened on one side of the support frame. A rotating roller is movably sleeved on the inner wall of the first circular through hole. A conveyor belt is rotatably connected to the outside of the rotating roller. Several first support plates are fixedly installed inside the support frame. A drive motor is fixedly installed on one side of the support frame. The drive shaft of the drive motor is fixedly installed with the rotating roller.

[0009] As a further embodiment of this utility model, a support pipe is fixedly installed on one side of the ring rolling mill body, a movable limiting frame is movably sleeved inside the support pipe, a hydraulic cylinder is installed inside the support pipe, the telescopic shaft of the hydraulic cylinder is fixedly installed with the movable limiting frame, the other end of the hydraulic cylinder is fixedly installed with the ring rolling mill body, and a limiting hole is opened on one side of the movable limiting frame, the limiting hole being movably sleeved with the support roller of the ring rolling mill body.

[0012] As a further embodiment of this utility model, a collection compartment is provided on the bottom surface of the support frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By using the coordinated operation of the ring rolling mill body, ring blank, dust hood, air suction pipe, and movable limit frame, a dust suction effect can be achieved.

The dust suction assembly is located on one side of the ring rolling mill body 1 and includes a dust suction hood 3, which is fixedly installed on one side of the core roller lifting platform of the ring rolling mill body 1. An air suction pipe 4 is connected to the top surface of the dust suction hood 3, the core roller of the ring rolling mill body 1 is located inside the dust suction hood 3, and a collection mechanism is provided on one side of the ring rolling mill body 1 for collecting the debris thrown out during the ring rolling of the ring blank 2.

[0025] In this embodiment, the collection mechanism includes: a support frame 9, which is fixedly installed on one side of the ring rolling mill body 1. Two first circular through holes are opened on one side of the support frame 9. A rotating roller 12 is movably sleeved on the inner wall of the first circular through hole. A conveyor belt 11 is rotatably connected to the outside of the rotating roller 12. Several first support plates 10 are fixedly installed inside the support frame 9. A drive motor 14 is fixedly installed on one side of the support frame 9. The drive shaft of the drive motor 14 is fixedly installed with the rotating roller 12. A ring rolling mill body 1 is fixedly installed on one side of the support frame 9. The device is equipped with a support pipe 6, and a movable limiting frame 5 is movably sleeved inside the support pipe 6. A hydraulic cylinder 7 is installed inside the support pipe 6.

[0026] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0027] During production, the suction pipe 4 of the ring rolling mill body 1 can be extended and connected to a blower to discharge hot air to the processing equipment. The suction pipe 4 is supported by a support member. When the operator needs to roll the ring blank 2, the hydraulic cylinder 7 is activated to push the moving limit frame 5 to move laterally under the support of the support pipe 6, so that the limit hole 8 moves out from the outside of the support roller of the ring blank 2. Then, the ring blank 2 is placed on the support roller of the ring rolling mill body 1. The hydraulic cylinder 7 is activated to retract, so that the moving limit frame 5 is reset and the limit hole 8 is placed on the support roller of the ring rolling mill body 1. Then, the hydraulic cylinder of the ring rolling mill body 1 is activated to push the core roller support frame to move the core roller downward. At the same time, other settings are made, and the ring rolling of the ring blank 2 can begin.

[0028] While the ring is being rolled, the blower is activated to draw air through the suction pipe 4 and the dust hood 3, creating a negative pressure at the bottom of the dust hood 3 for dust collection. Simultaneously, the debris thrown out by the rotating ring blank 2 falls onto the top of the support frame 9, passes through the gaps between several first support plates 10, and falls onto the top surface of the conveyor belt 11. Larger pieces are manually broken and fall. The drive motor 14 is activated to drive the rotating roller 12, which in turn drives the conveyor belt 11 to transport the debris. The conveyor belt 11 is made of stainless steel or other suitable high-temperature resistant materials to prevent burns from high temperatures. The debris moves and falls into the collection bin 16 for collection, eliminating the need for manual cleaning. At the same time, the U-shaped first support plate 10 increases the support strength, and it is not obstructed by personnel standing on it, making it quite practical.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
