Description

Technical Field

[0001] This invention relates to the field of ring forging machine technology, specifically to a mechanical device structure for a ring forging machine with inclined main roll support. Background Technology

[0002] When rolling ring forgings of different specifications and cross-sectional shapes, the tilt angle of the main roll is often adjusted according to the process requirements to ensure the forming quality and processing adaptability of the rings. Most of the existing ring forging mills have a simple main roll tilt angle adjustment mechanism and the adjustment method is relatively cumbersome, which makes it difficult to meet the needs of rapid changeover of diverse rings.

[0003] Currently, most common main roll drive and support structures use a single power source to drive the main roll to move on one side to achieve tilt angle changes. This is prone to problems such as asynchronous lifting and lowering at both ends of the main roll, movement deviation, and uneven force. Not only is the tilt angle adjustment accuracy low, but it also easily causes the main roll to wobble and jam, affecting the roundness and wall thickness uniformity of the rolled ring. At the same time, traditional structures are complicated to operate when adjusting the tilt angle of the main roll, and the adjustment response is slow. They cannot easily and flexibly switch the tilt angle according to the processing requirements of different rings, resulting in low equipment versatility and production efficiency. In addition, although some fixed tilt support structures have good stability, the tilt angle is not adjustable and can only be adapted to the processing of a single type of ring. They have poor adaptability to irregularly shaped rings and variable angle rolling conditions, which limits the scope of equipment use. Summary of the Invention

[0004] The purpose of this invention is to provide a mechanical device structure for a ring forging mill with a tilted main roll support, in order to solve the problems mentioned in the background art. The common main roll drive and support structures often use a single power source to drive the main roll to move on one side to achieve tilt angle changes. This easily leads to problems such as asynchronous lifting and lowering at both ends of the main roll, movement deviation, and uneven force. Not only is the tilt angle adjustment accuracy low, but it also easily causes the main roll to wobble and jam, affecting the roundness and wall thickness uniformity of the rolled ring. Furthermore, traditional structures are complex to operate when adjusting the tilt angle of the main roll, with slow adjustment response, and cannot easily and flexibly switch tilt angles according to the processing requirements of different rings. This results in low equipment versatility and production efficiency. In addition, while some fixed tilt support structures have good stability, the tilt angle is not adjustable, and they can only be adapted to processing a single type of ring. They have poor adaptability to irregularly shaped rings and variable angle rolling conditions, limiting the scope of equipment application.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mechanical device structure for a ring forging machine with inclined main roll support, comprising a base frame supported on a support surface, wherein a front frame, a support frame, and a bottom cylinder are vertically fixed to the upper wall of the base frame from left to right, and connecting pieces are movably connected to the end walls of the support frame and the front frame in a vertical direction, a motor is driven to the bottom cylinder, a drive shaft is driven to the end of the motor, a main roll is fixed to the end of the drive shaft, a pair of guide rolls for rolling ring forgings are arranged on the lower side of the main roll and are rotatably connected to the base frame and the front frame, the main roll is rotatably connected to the connecting pieces, and a top cylinder is invertedly fixed to the top side wall of the support frame, and a connecting piece movably connected to the front frame is driven to the end of the top cylinder.

[0006] Preferably, the base frame is rectangular, while the support frame is L-shaped, and the support frame and the front frame end wall are respectively provided with a rear sliding groove and a front sliding groove.

[0008] Preferably, there are two front slide rails and two rear slide rails, and the end walls of the front slide block and the rear slide block are connected to a bearing shaft that is connected to the front slide rail and the rear slide rail.

[0009] Preferably, a motor mount is fixedly connected to the end wall of the motor, the motor mount is driven to the end of the bottom cylinder, and the bottom end of the top cylinder is driven to the front connecting seat fixedly connected to a pair of front slide rails.

[0010] Preferably, the support frame and the front frame are respectively provided with connection ports near the top of the rear slide groove and the front slide groove, and the connection ports are internally threaded to the connecting cylinder.

[0011] Preferably, the connecting cylinder has an annular recess on its outer wall at the middle part, a circular cavity inside the connecting cylinder, and an inlet communicating with the cavity on the upper wall near the center of the connecting cylinder.

[0012] Preferably, the connecting cylinder has a threaded annular sealing sleeve at the concave end wall, which rotates and moves laterally to open and close the inlet.

[0013] Preferably, a ring-shaped cotton sleeve made of sponge material is glued to the outer wall of both ends of the connecting cylinder near the cylinder recess, and a mesh hole communicating with the cavity opening is opened in a ring shape on the end wall of the connecting cylinder near the cotton sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the top cylinder and bottom cylinder drive downwards synchronously, driving the connecting parts to move downwards synchronously, allowing the main roller to feed downwards for ring forging. The top cylinder and bottom cylinder drive upwards and downwards, changing the tilt of the connecting parts and driving the main roller to change the tilt angle to adapt to different tilt processing requirements of ring forgings. This provides greater controllability during processing.

Tighten the threaded connection of the connecting cylinder in the connection port. At the cotton sleeve on the end wall of the connecting cylinder, lubricant slowly seeps down. The lubricant flows into the rear slide groove and the front slide groove to lubricate and maintain the rear slide groove, the front slide groove, the front slide rail, and the rear slide rail, thus playing a role in the auxiliary maintenance of the front slide rail and the rear slide rail. 4. The sealing sleeve is used for rotational lateral movement and opening / closing of the inlet. The inlet is used to add lubricant towards the cavity opening. Attached Figure Description

[0021] Please see Figure 1-5This invention provides a technical solution: a mechanical device structure for a ring forging machine with inclined main roller support, including a base frame 1 supported on a support surface. From left to right, a front frame 8, a support frame 3, and a bottom cylinder 2 are vertically fixed to the upper wall of the base frame 1. Connectors are vertically connected to the end walls of the support frame 3 and the front frame 8. A motor 5 is driven to the bottom cylinder 2, and a drive shaft 6 is driven to the end of the motor 5. A main roller 15 is fixed to the end of the drive shaft 6. A pair of guide rollers, rotatably connected to the base frame 1 and the front frame 8 and used to crush ring forgings, are arranged on the lower side of the main roller 15. The main roller 15 is rotatably connected to the connecting components. A top cylinder 22 is invertedly fixed to the top side wall of the support frame 3. The connecting parts at the front frame 8 of the head transmission are movably connected. The top cylinder 22 and the bottom cylinder 2 drive downward synchronously, driving the connecting parts to move downward synchronously, allowing the main roller 15 to feed downward for ring forging. The top cylinder 22 and the bottom cylinder 2 drive up and down, which changes the tilt of the connecting parts and drives the main roller 15 to change the tilt angle to adapt to different tilt processing requirements of ring forgings. The controllability during processing is stronger. At the same time, when the top cylinder 22 and the bottom cylinder 2 drive up and down, the connecting parts and the transmission shaft 6 rotate relative to each other to assist in the tilt adjustment of the drive shaft 6 and the main roller 15. The main roller 15 is driven to rotate by the motor 5 and cooperates with the guide roller to process the ring forging. The base frame 1 is rectangular, while the support frame 3 is L-shaped. The support frame 3 and the front frame 8 are respectively provided with a rear slide groove 7 and a front slide groove 9. The support frame 3 is L-shaped, which facilitates the fixed connection of the top cylinder 22 to the top side wall. The top cylinder 22, along with the rear slide groove 7 and the front slide groove 9, are used to movably connect the rear slide rail 13 and the front slide rail 12, thereby moving the rear slide block 11 and the front slide block 10 to change the height position, so as to drive the drive shaft 6 and the main roller 15 to move, so as to facilitate the feeding of the rolling ring forging by the main roller 15. The connecting parts include the front slide rail 12 and the rear slide rail 13 that are respectively fitted into the rear slide groove 7 and the front slide groove 9, the front slide block 10 that is rotatably connected to the inner side of the front slide rail 12, and the rear slide block 11 that is rotatably connected to the inner side of the rear slide rail 13. Two front slide rails 12 and two rear slide rails 13 are provided. At the same time, the end walls of the front slide block 10 and the rear slide block 11 are connected to the bearing shafts 14 connected to the front slide rails 12 and the rear slide rails 13. The front slide block 10 and the rear slide block 11 can rotate so that when the front slide block 10 and the rear slide block 11 are driven up and down, the front slide block 10 and the rear slide block 11 rotate to change the tilt angle of the transmission shaft 6 and the main roller 15, thereby using forgings with different rolling ring requirements. Motor base 4 is fixedly connected to the end wall of motor 5. Motor base 4 is connected to the end of bottom oil cylinder 2 via transmission. At the same time, the bottom end of top cylinder 22 is connected to the front connecting seat 23, which is fixedly connected to a pair of front slide rails 12 via transmission. The support frame 3 and the front frame 8 are respectively provided with connection ports 16 near the top of the rear slide groove 7 and the front slide groove 9. The connection port 16 is internally threaded to the connecting cylinder 17. The middle outer wall of the connecting cylinder 17 is provided with an annular cylindrical recess 18. The connecting cylinder 17 is provided with a circular cavity. The connecting cylinder 17 is provided with an inlet 19 near the center upper wall, which communicates with the cavity. The connection port 16 is used to thread the end walls of the two ends of the connecting cylinder 17, which facilitates the disassembly and assembly of the connecting cylinder 17 and makes it easy to use. The inlet 19 of the connecting cylinder 17 is used to add lubricant towards the cavity. A circular sealing sleeve 20 is threaded to the end wall of the recess 18 of the connecting cylinder 17. The sealing sleeve 20 rotates and moves laterally to open and close the inlet 19. The sealing sleeve 20 rotates and moves laterally to change its position at the inlet 19. It moves laterally away from the inlet 19, and the inlet 19 is opened. Lubricant can be added or cleaned. It moves to the inlet 19 to protect the inlet 19 and facilitates simple sealing of the lubricant in the inlet 19. Both ends of the connecting cylinder 17 have annular sponge sleeves 21 attached to the outer walls near the cylinder recesses 18. The end walls of the connecting cylinder 17 near the sleeves 21 have annular mesh openings that communicate with the cavity openings. Lubricating fluid slowly seeps into the sponge sleeves 21 along the mesh openings. After absorbing the lubricating fluid, the sleeves 21 slowly seep down along the rear slide groove 7 and the front slide groove 9, lubricating the end walls of the rear slide groove 7 and the front slide groove 9, making the front slide rail 12 and the rear slide rail 13 move more smoothly and stably.

[0022] In summary, the mechanical structure of this ring forging machine with inclined main roll support is suitable for use... The base frame 1 is supported on the support surface. The front frame 8, the support frame 3, and the bottom oil cylinder 2 are all vertically fixed to the base frame 1. During use, the forging is placed between the guide roller and the main roller 15. The main roller 15 is driven by the transmission shaft 6 driven by the motor 5 to rotate. Then, the top cylinder 22 and the bottom oil cylinder 2 move synchronously, driving the front slide 10 and the rear slide 11 to move and displace, thereby driving the transmission shaft 6 and the main roller 15 to move and displace, allowing the main roller 15 to feed in and extrude and roll the ring forging, which facilitates the ring processing. During adjustment, the front slide block 10 and the rear slide block 11 are moved up and down respectively to change the angle of the main roller 15 when it is fed, so as to facilitate the adjustment of the tilt angle and perform different tilt angle processing on the forging. The front slide block 10 is connected to two front slide rails 12 via a bearing shaft 14, and the rear slide block 11 is connected to two rear slide rails 13 via a bearing shaft 14. The rear slide rails 13 move in the rear slide groove 7, and the front slide rails 12 move in the front slide groove 9, which is used to change the stable movement of the front slide block 10 and the rear slide block 11 and change their position and height. The connecting sleeve 17 is connected to the screw thread in the connecting port 16. At the cotton sleeve 21 on the end wall of the connecting sleeve 17, lubricating fluid slowly seeps down and flows into the rear slide groove 7 and the front slide groove 9 to lubricate and maintain the rear slide groove 7, the front slide groove 9, the front slide rail 12, and the rear slide rail 13, and to assist in the maintenance of the front slide rail 12 and the rear slide rail 13. The sealing sleeve 20 is used for rotational lateral movement to open and close the inlet 19, which is used to add lubricant toward the cavity opening.
