Description

Technical Field

[0001] This utility model relates to the field of ring rolling machine technology, specifically a vertical ring rolling machine. Background Technology

[0002] The ring rolling mill is a long-established rotary forging equipment. The vertical ring rolling mill is driven by an electric motor to rotate the main rolling roller. During the downward pressure process, it forms a pair of rollers with the passively rotating mandrel. The ring blank on the mandrel is repeatedly rolled in a cycle, and the inner and outer diameters of the ring are expanded and the wall thickness is reduced to gradually form the ring.

[0003] A ring rolling mill is equipped with a main rolling roller, a core roller, and auxiliary rolling rollers. When the main rolling roller descends and applies pressure to work with the core roller to roll the ring blank fitted on the core roller, the auxiliary rolling roller rotates to a suitable position under the drive of the adjusting cylinder. This assists the main rolling roller and the core roller in performing a more comprehensive and stable rolling operation on the ring blank. There are usually two sets of auxiliary rolling rollers, each driven and adjusted by two sets of adjusting cylinders. This increases the cost of the drive equipment, reduces the cost of the ring rolling mill drive equipment, and decreases the economic efficiency of the ring rolling mill. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical ring rolling mill to solve the problem mentioned in the background art that the existing ring rolling mill has two sets of auxiliary rolling rollers, which are driven and adjusted by two sets of adjusting cylinders, thus increasing the cost of the driving equipment and reducing the economic efficiency of the ring rolling mill.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical ring rolling mill, comprising a base plate, a support plate fixedly connected to the surface of the base plate, a drive motor fixedly connected to the surface of the support plate, a core roller fixedly connected to the output shaft of the drive motor, an adjustment mechanism provided on the surface of the base plate, the adjustment mechanism including a guide rod fixedly connected to the surface of the base plate, a lifting rod slidably connected to the surface of the guide rod, an adjustment frame rotatably connected to the surface of the support plate, a secondary rolling roller rotatably connected to the surface of the adjustment frame, and an adjustment connecting rod rotatably connected to the surface of the lifting rod, the end of the adjustment connecting rod away from the lifting rod being rotatably connected to... An adjusting cylinder is fixedly connected to the surface of the base plate, and the bottom of the lifting rod is fixedly connected to the piston rod of the adjusting cylinder. A switching mechanism is provided on the surface of the support plate. The switching mechanism includes a crushing cylinder, which is fixedly connected to the surface of the support plate. A lifting block is fixedly connected to the piston end of the crushing cylinder. A rotating shaft is rotatably connected to the bottom of the lifting block. A connecting block is fixedly connected to the surface of the rotating shaft. A main crushing roller is rotatably mounted on the surface of the connecting block. A return spring is fixedly connected to the surface of the lifting block. A limit rod is fixedly connected to the surface of the return spring and slidably connected to the surface of the lifting block.

[0006] Preferably, the guide rod is provided in two sets, and the lifting rod moves horizontally up and down on one side of the support plate via the guide rod, and the adjusting cylinder drives the lifting rod to slide horizontally up and down.

[0007] Preferably, there are two sets of adjusting rods and adjusting frames, and the two sets of adjusting frames are symmetrically distributed on the support plate. During the lifting process, the lifting rod drives one end of the two sets of adjusting rods to rotate and move, and the adjusting rod drives the adjusting frame to rotate on the surface of the support plate through rotation.

[0008] Preferably, the adjusting frame is triangular in shape, and the two sets of adjusting frames rotate in opposite directions, with the adjusting frame driving the auxiliary rolling roller to rotate synchronously.

[0009] Preferably, a guide groove is formed on the surface of the support plate, and the rolling cylinder drives the lifting block to slide and rise on the guide groove of the support plate through the piston rod. The lifting block is in the shape of a "U".

[0010] Preferably, the connecting block is T-shaped, and there are two sets of main rollers, which are symmetrically distributed on the connecting block. The connecting block rotates on the lifting block via a rotating shaft.

[0011] Preferably, a limiting hole is formed on the surface of the connecting block, and the limiting rod is inserted into the limiting hole of the connecting block by the elastic force of the return spring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This ring rolling mill uses an adjusting cylinder to drive a lifting rod to move horizontally up and down along a guide rod. The lifting rod drives the symmetrically distributed adjusting frame to rotate through an adjusting connecting rod, so that the auxiliary rolling rollers rotate synchronously to the appropriate position to assist in rolling. Compared with the traditional method of using two sets of adjusting cylinders to drive separately, this method reduces the use of one set of driving equipment, significantly reduces costs, and effectively improves the economy of the ring rolling mill.

[0013] 2. This ring rolling mill uses a reset spring to push a limit rod into the limit hole of the connecting block, fixing the connecting block and ensuring the stable operation of the main rolling roller. When the main rolling roller needs to be replaced, the operator pulls out the limit rod, the connecting block rotates 180 degrees around the shaft, so that the spare main rolling roller is moved to the working area, and then the limit rod is inserted to fix the connecting block. This process is quick and convenient, greatly reducing equipment downtime and effectively improving the working efficiency of the ring rolling mill. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: A vertical ring rolling mill includes a base plate 1, a support plate 11 fixedly connected to the surface of the base plate 1, a drive motor 12 fixedly connected to the surface of the support plate 11, a core roller 13 fixedly connected to the output shaft of the drive motor 12, an adjustment mechanism on the surface of the base plate 1, the adjustment mechanism including a guide rod 2 fixedly connected to the surface of the base plate 1, a lifting rod 21 slidably connected to the surface of the guide rod 2, an adjustment frame 23 rotatably connected to the surface of the support plate 11, a secondary rolling roller 24 rotatably connected to the surface of the adjustment frame 23, an adjustment connecting rod 22 rotatably connected to the surface of the lifting rod 21, one end of the adjustment connecting rod 22 away from the lifting rod 21 rotatably connected to the surface of the adjustment frame 23, an adjustment cylinder 25 fixedly connected to the surface of the base plate 1, the bottom of the lifting rod 21 fixedly connected to the piston rod of the adjustment cylinder 25, and a switching mechanism on the surface of the support plate 11, the switching mechanism including a rolling air... Cylinder 3, the crushing cylinder 3 is fixedly connected to the surface of the support plate 11. A lifting block 31 is fixedly connected to the piston end of the crushing cylinder 3. A rotating shaft 32 is rotatably connected to the bottom of the lifting block 31. A connecting block 33 is fixedly connected to the surface of the rotating shaft 32. A main crushing roller 34 is rotatably mounted on the surface of the connecting block 33. A return spring 35 is fixedly connected to the surface of the lifting block 31. A limit rod 36 is fixedly connected to the surface of the return spring 35. The limit rod 36 is slidably connected to the surface of the lifting block 31. Its adjustment mechanism can be driven and adjusted by a set of adjustment cylinders 25, reducing the use of a set of drive equipment and improving the economy of the ring crushing machine. Its switching mechanism can rotate the spare main crushing roller 34 on the side of the connecting block 33 to the working area when the main crushing roller 34 needs to be replaced, thereby replacing the main crushing roller 34 that needs to be replaced, reducing the downtime of the ring crushing machine and improving the working efficiency of the ring crushing machine.

[0018] Furthermore, the guide rod 2 is provided in two sets. The lifting rod 21 moves horizontally up and down on one side of the support plate 11 via the guide rod 2. The adjusting cylinder 25 drives the lifting rod 21 to slide horizontally up and down. The two sets of guide rods 2 are parallel and vertically fixed to the surface of the base plate 1. Their surfaces are finely polished to reduce the friction between them and the lifting rod 21, ensuring that the lifting rod 21 can slide smoothly along the guide rod 2.

[0019] Furthermore, there are two sets of adjusting rods 22 and adjusting frames 23, and the two sets of adjusting frames 23 are symmetrically distributed on the support plate 11. During the lifting and lowering process, the lifting rod 21 drives one end of the two sets of adjusting rods 22 to rotate and move. The adjusting rods 22 drive the adjusting frames 23 to rotate on the surface of the support plate 11 through rotation. When the lifting rod 21 is lifted and lowered, the adjusting rods 22 will rotate and move accordingly with the movement of the lifting rod 21, thereby transmitting force to the adjusting frames 23 and driving the adjusting frames 23 to rotate around their rotation center, so as to achieve precise adjustment of the position of the auxiliary rolling roller 24.

[0020] Furthermore, the adjusting frame 23 is triangular in shape, and the two sets of adjusting frames 23 rotate in opposite directions. The adjusting frame 23 drives the auxiliary rolling roller 24 to rotate synchronously. The two sets of adjusting frames 23 rotate in opposite directions so that the two auxiliary rolling rollers 24 can apply pressure to the ring blank from different directions, thereby making the ring blank more uniformly stressed during the rolling process and improving the rolling quality.

[0021] Furthermore, a guide groove is provided on the surface of the support plate 11. The rolling cylinder 3 drives the lifting block 31 to slide and rise on the guide groove of the support plate 11 through the piston rod. The lifting block 31 is in the shape of a "U". This shape design can provide sufficient installation space for the internal rotating shaft 32 and connecting block 33, and can ensure the stability of the lifting block 31 when sliding in the guide groove.

[0022] Furthermore, the connecting block 33 is T-shaped, and two sets of main rollers 34 are provided. The two sets of main rollers 34 are symmetrically distributed on the connecting block 33. The connecting block 33 rotates on the lifting block 31 via the rotating shaft 32. The two sets of main rollers 34 are installed at both ends of the connecting block 33 via bearings to ensure that the main rollers 34 can rotate flexibly.

[0023] Furthermore, a limiting hole is formed on the surface of the connecting block 33. The limiting rod 36 is inserted into the limiting hole of the connecting block 33 by the elastic force of the return spring 35. When the connecting block 33 rotates to the appropriate position, the elastic force of the return spring 35 will push the limiting rod 36 into the limiting hole of the connecting block 33, fixing the connecting block 33 in the current position, preventing the connecting block 33 from rotating unexpectedly during the rolling process, and ensuring that the main rolling roller 34 can work stably.

[0024] Working principle: When the regulating cylinder 25 is activated, the piston rod extends and retracts, driving the lifting rod 21 to move horizontally up and down along the guide rod 2. Two sets of regulating connecting rods 22 are rotatably connected to the surface of the lifting rod 21. The other end of the regulating connecting rod 22 is rotatably connected to the regulating frame 23. The two sets of regulating frames 23 are symmetrically distributed on the support plate 11 in a triangular shape and can rotate around the support plate 11. When the lifting rod 21 moves up and down, it drives one end of the regulating connecting rod 22 to rotate and move. The regulating connecting rod 22 transmits force to the regulating frame 23, driving the regulating frame 23 to rotate. The two sets of regulating frames 23 rotate in opposite directions, thereby driving the auxiliary rolling rollers 24 to rotate synchronously to the appropriate position to assist rolling. The entire process uses only one set of regulating cylinders 25 to drive and adjust the two auxiliary rolling rollers 24. Compared with using two sets of regulating cylinders to drive them separately, this reduces the use of one set of drive equipment, lowers costs, and improves the economy of the ring rolling mill.

[0025] The limit rod 36 is inserted into the limit hole of the connecting block 33 by the return spring 35, and the connecting block 33 is fixed. When the main roller 34 needs to be replaced, the operator overcomes the elastic force of the return spring 35 and pulls out the limit rod 36. The connecting block 33 can rotate around the rotating shaft 32. Rotating the connecting block 33 180 degrees makes the spare main roller 34 turn to the working area. The limit rod 36 is released, and the return spring 35 pushes the limit rod 36 to insert into the new limit hole, fixing the connecting block 33 and completing the replacement of the main roller 34. This reduces equipment downtime and improves work efficiency.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
