Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary equipment for ring rolling machines, and particularly to a transfer structure for use with ring rolling machines. Background Art

[0002] With the continuous progress of modern industrial technology, the requirements for the processing accuracy and efficiency of parts in the field of mechanical manufacturing are also increasing day by day. As a type of special forging equipment, ring rolling machines are mainly used to produce various types of ring-shaped parts, such as gears, flanges, bearing rings, etc. These parts are widely used in many important industries such as automobiles, aviation, ships, and energy. The ring rolling process gradually compresses a metal blank into the required ring shape under a strong pressure in a rotating state to obtain products with high precision and high strength.

[0003] In order to achieve an efficient production process, ring rolling machines usually need to be equipped with a transfer structure to assist in the loading and unloading of finished metal rings. This transfer structure can not only improve work efficiency, reduce errors caused by manual operations, but also ensure worker safety and reduce labor intensity. However, when transferring metal rings, the traditional transfer structure requires workers to complete the connection work between the transfer structure and the metal ring. Since the temperature of the metal ring is relatively high, it is extremely easy to cause harm to workers, and some transfer structures use power sources such as cylinders and motors to complete the connection work, and the high temperature will also damage such equipment. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a transfer structure for use with a ring rolling machine, and the specific technical solution adopted is as follows: According to a first aspect of the present invention, there is provided a transfer structure for use with a ring rolling machine, including a suspension rod and a plurality of support arms connected to the suspension rod. A support seat is provided on each support arm, and a sliding rod and a first threaded rod are provided at the bottom of the support seat. The sliding rod is vertical, and the top of the sliding rod slidably passes through the support seat. A clamping structure is provided at the top of the support seat. A moving plate is provided at the bottom of the sliding rod. The top of the first threaded rod is rotatably connected to the support seat, and a support plate for lifting the metal ring is provided at the bottom of the first threaded rod. The first threaded rod passes through the moving plate and is threadedly connected to each other; Wherein, when the sliding rod moves upward, the clamping structure locks the height position of the sliding rod.

[0005] Further, the clamping structure includes a slider slidably mounted horizontally on the sliding rod. An elastic telescopic rod is horizontally provided on the side wall of the slider, and the slider is connected to the sliding rod through a first elastic sheet; A side platform is fixed on the support base. An annular groove is formed on the side wall of the side platform facing the sliding rod. Both the upper and lower sides of the annular groove are inclined and parallel to each other. Both the front and rear sides of the annular groove are vertical. A deep groove is formed in the annular groove. One end of the deep groove is located in a vertical side of the annular groove and forms a stepped shape with the inner wall of the annular groove. The other end of the deep groove extends into the other vertical side of the annular groove and is transitioned with the inner wall of the annular groove through an inclined surface. Wherein, in the natural state, the first elastic sheet pulls the slider to be located in the middle of the slider stroke, and the movable end of the elastic telescopic rod slides in the annular groove.

[0006] Furthermore, a side plate is rotatably arranged at the end of the support plate away from the first threaded rod. A first pull rod is horizontally slidably arranged on the side wall of the support plate. The first pull rod and the side plate are rotatably connected through an inclined second pull rod.

[0007] Furthermore, a prism is slidably inserted through the bottom of the first threaded rod. The prism is fixedly connected with the support plate. A guide plate is inclinedly arranged on the outer wall of the first threaded rod. A guide sleeve is slidably sleeved on the guide plate. The guide sleeve is fixedly connected with the first pull rod. The guide plate and the guide sleeve are connected through a second elastic sheet.

[0008] Furthermore, the rotation axis of the side plate on the support plate is located above the rotation axis of the second pull rod on the first pull rod.

[0009] Furthermore, the support base is slidably installed on the support arm.

[0010] Furthermore, multiple support arms are circularly distributed. The length direction of the support arm is along the radial direction of the circle where the multiple support arms are located. The ends of the multiple support arms are butt-jointed with each other and form a central position. A second threaded rod is screwed and inserted through the central position. The second threaded rod and the central position are locked through a lock nut. A top plate is rotatably arranged at the end of the second threaded rod. Multiple first connecting arms are inclinedly rotatably arranged on the outer wall of the top plate. A second connecting arm is horizontally arranged on the side wall of each support base. The second connecting arm horizontally slides on the support arm. The second connecting arm is rotatably connected with the first connecting arm.

[0011] Furthermore, the suspension rod and each support arm are connected through a pull rope. The lengths of the multiple pull ropes are equal.

[0012] The beneficial effects of the present invention are as follows: This structure can automatically rotate the support plate under or away from the metal ring by utilizing the gravity of the support arm and the structures thereon, so as to realize the automatic connection work with the metal ring, thereby avoiding the harm to the human body caused by high temperature during manual operation. At the same time, its structure is simple and the operation is convenient. Since there is no need to adopt a traditional power source to provide power for the rotation of the support plate, the damage to the power source caused by high temperature can be avoided, and the service life of the equipment can be improved.

Detailed Description of the Invention

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0017] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings.

[0018] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. This embodiment is written in a progressive manner.

[0019] As Figures 1 to 5 shown, a transfer structure for use with a ring rolling machine according to the present invention includes a suspension rod 1 and a plurality of support arms 2 connected to the suspension rod 1. A support seat 3 is provided on each support arm 2. A slide bar 4 and a first threaded rod 5 are provided at the bottom of the support seat 3. The slide bar 4 is vertical, and the top of the slide bar 4 slidably passes through the support seat 3. A clamping structure is provided at the top of the support seat 3. A moving plate 6 is provided at the bottom of the slide bar 4. The top of the first threaded rod 5 is rotatably connected to the support seat 3. A support plate 7 for lifting a metal ring 27 is provided at the bottom of the first threaded rod 5. The first threaded rod 5 passes through the moving plate 6 and is threadedly connected to each other; Among them, when the slide bar 4 moves upward, the clamping structure locks the height position of the slide bar 4.

[0020] Specifically, the pallets 7 on the multiple support arms 2 can lift the metal ring 27 from multiple positions, which can ensure the stable transfer of the metal ring 27. The suspension rod 1 is used for hoisting the metal ring 27. During use, the length direction of the pallet 7 deviates from the suspension rod 1. The multiple support arms 2 and the structures thereon are hoisted above the metal ring 27 by the suspension rod 1 and then the support arms 2 and the structures thereon are lowered. At this time, since the length direction of the pallet 7 deviates from the suspension rod 1, the multiple first threaded rods 5 can smoothly move down to the outside of the metal ring 27, and the pallet 7 will not block the metal ring 27. When the metal ring 27 contacts the moving plate 6, the moving plate 6 stops moving. Due to the action of the self-weight of the support arms 2 and the structures thereon, relative movement will occur between the support seat 3 and the sliding rod 4, that is, relative movement will occur between the moving plate 6 and the first threaded rod 5. Since the first threaded rod 5 is threadedly connected to the moving plate 6, the first threaded rod 5 will rotate at the bottom of the support seat 3. At this time, the first threaded rod 5 drives the pallet 7 to rotate, and the pallet 7 moves from the outside of the metal ring 27 to below the metal ring 27. At this time, the preparation work for the pallet 7 to lift is completed. The clamping structure locks the position of the sliding rod 4. When the suspension rod 1 moves up and hoists, the pallet 7 moves up and lifts the metal ring 27. At this time, the metal ring 27 is transferred in position by being lifted by the multiple pallets 7. When the metal ring 27 moves to the target position, the suspension rod 1 and the support seat 3 move down a small distance to separate the pallet 7 from the metal ring 27. The clamping structure releases the locking work on the sliding rod 4, and the sliding rod 4 naturally moves down to the initial position due to gravity. At this time, the first threaded rod 5 and the pallet 7 rotate and the pallet 7 offsets outside the metal ring 27. The suspension rod 1 moves up again and moves the support arms 2 and the structures thereon away from the metal ring 27, thereby realizing the work of transferring the metal ring 27 from the ring rolling mill to the specified position. This structure can make the pallet 7 automatically rotate below the metal ring 27 or deviate from the metal ring 27 by using the gravity of the support arms 2 and the structures thereon, and can realize the automatic connection work with the metal ring 27, thus avoiding the harm of high temperature to the human body when manual operation is required. At the same time, its structure is simple and the operation is convenient. Since there is no need to use a traditional power source to provide power for the rotation of the pallet 7, the damage of high temperature to the power source can be avoided, and the service life of the equipment can be improved; During actual processing, since a part of the formed metal ring 27 extends outside the ring rolling mill, space can be provided for the movement of the pallet 7.

[0021] Further, the clamping structure includes a slider 8 horizontally slidably mounted on the sliding rod 4. An elastic telescopic rod 9 is horizontally arranged on the side wall of the slider 8. The slider 8 is connected to the sliding rod 4 through a first elastic sheet 10; A side platform 11 is fixed on the support base 3. An annular groove 12 is formed on the side wall of the side platform 11 facing the sliding rod 4. The upper and lower sides of the annular groove 12 are inclined and parallel to each other. The front and rear sides of the annular groove 12 are vertical. A deep groove 13 is formed in the annular groove 12. One end of the deep groove 13 is located in a vertical side of the annular groove 12 and forms a stepped shape with the inner wall of the annular groove 12. The other end of the deep groove 13 extends to the other vertical side of the annular groove 12 and is transitioned with the inner wall of the annular groove 12 through an inclined surface; Wherein, in the natural state, the first elastic piece 10 pulls the slider 8 to be located in the middle of the stroke of the slider 8, and the movable end of the elastic telescopic rod 9 slides in the annular groove 12.

[0022] Specifically, the elastic telescopic rod 9 can perform elastic telescopic movement. The fixed end of the elastic telescopic rod 9 is installed on the slider 8, and the movable end of the elastic telescopic rod 9 is located in the annular groove 12. When the moving plate 6 is lifted by the metal ring 27 and moves upward relative to the support seat 3, the slide rod 4 will push the elastic telescopic rod 9 to slide in the annular groove 12 through the slider 8 thereon. When the movable end of the elastic telescopic rod 9 moves to the step position between the annular groove 12 and the deep groove 13, the support plate 7 rotates to the lower side of the metal ring 27. At this time, the hanging rod 1 lifts. Due to the gravity of the slide rod 4 and the moving plate 6, the movable end of the elastic telescopic rod 9 will be stuck at the step position, thereby limiting the position of the moving plate 6. At this time, since the elastic telescopic rod 9 is located in a vertical side of the annular groove 12, the elastic telescopic rod 9 and the slider 8 deviate from the midpoint position of the slider 8 stroke, and the first elastic sheet 10 undergoes elastic deformation. When the metal ring 27 moves to the specified position, the hanging rod 1 moves downward and causes the support arm 2 and the structures thereon to move downward synchronously. The support plate 7 is separated from the metal ring 27, and the moving plate 6 comes into contact with the metal ring 27 again. At this time, the support seat 3 continues to move downward and moves relative to the moving plate 6, and the slide rod 4 slides relative to the support seat 3. The slide rod 4 pushes the elastic telescopic rod 9 thereon to move upward in a vertical side of the annular groove 12. When the elastic telescopic rod 9 moves to the inclined side on the upper side of the annular groove 12, due to the action of the first elastic sheet 10, the elastic telescopic rod 9 will tend to move towards the midpoint position of the moving stroke of the slider 8. At this time, the hanging rod 1 lifts the support seat 3. Due to the gravity of the slide rod 4 and the moving plate 6, and the guiding action of the inclined upper side of the annular groove 12, the elastic telescopic rod 9 will move from one vertical side to another vertical side. The inclined plane of the annular groove 12 and the deep groove 13 can make the elastic telescopic rod 9 slide into the annular groove 12 from the deep groove 13. At this time, the slide rod 4 and the moving plate 6 can move downward smoothly. The moving plate 6 pushes the first threaded rod 5 and the support plate 7 to rotate and reset. When the elastic telescopic rod 9 moves to the lowest point position of the annular groove 12, the slide rod 4 stops moving. When the metal ring 27 is transferred again, the metal ring 27 contacts the moving plate 6 and pushes the elastic telescopic rod 9 to slide from the inclined bottom edge of the annular groove 12 into the vertical side of the annular groove 12 and move to the step position between the annular groove 12 and the deep groove 13 again, thereby realizing the blocking work of the slide rod 4 and the support plate 7 again. This structural method can realize automatic unlocking and locking work without manual operation or power source providing power. Its structure is simple and the functionality is strong.

[0023] Further, a side plate 14 is rotatably provided at the end of the support plate 7 away from the first threaded rod 5. A first pull rod 15 is horizontally slidably provided on the side wall of the support plate 7. The first pull rod 15 is rotatably connected to the side plate 14 through an inclined second pull rod 16.

[0024] Specifically, when the pallet 7 contacts the bottom of the metal ring 27, the second pull rod 16 can be used to push the side plate 14 to rotate from the horizontal state to the vertical state by pulling the first pull rod 15 to move horizontally. At this time, the side plate 14 contacts the circumferential inner wall of the metal ring 27. In this way, the side plate 14 can be used to further limit the metal ring 27, prevent the metal ring 27 from detaching from the pallet 7, and prevent the metal ring 27 from moving randomly on the pallet 7.

[0025] Further, a prism 17 is slidably inserted through the bottom of the first threaded rod 5. The prism 17 is fixedly connected to the pallet 7. A guide plate 18 is inclined on the outer wall of the first threaded rod 5. A guide sleeve 19 is slidably sleeved on the guide plate 18. The guide sleeve 19 is fixedly connected to the first pull rod 15. The guide plate 18 and the guide sleeve 19 are connected by a second elastic sheet 20.

[0026] Specifically, when the hanging rod 1 lifts the pallet 7 upward, the pallet 7 contacts the bottom of the metal ring 27. At this time, the pallet 7 stops moving, and the first threaded rod 5 continues to move upward. Relative movement occurs between the guide plate 18 and the guide sleeve 19. Since the guide plate 18 is inclined, the guide sleeve 19 will displace in the horizontal direction. The guide sleeve 19 pulls the first pull rod 15 to move, thereby providing power for the side plate 14 to rotate on the pallet 7. The second elastic sheet 20 can help the guide plate 18 and the guide sleeve 19 to reset when idle. The setting of the prism 17 can keep the first threaded rod 5 and the pallet 7 in a synchronous rotation state.

[0027] Further, the rotation axis of the side plate 14 on the pallet 7 is located above the rotation axis of the second pull rod 16 on the first pull rod 15.

[0028] Specifically, by limiting the positions of the rotation axis of the side plate 14 on the pallet 7 and the rotation axis of the second pull rod 16 on the first pull rod 15, it is convenient to make the second pull rod 16 pull the side plate 14 to the horizontal state, thereby conveniently reducing the space occupied by the pallet 7 and the side plate 14 in the vertical direction, and facilitating the movement of the pallet 7 below the metal ring 27 or away from below the metal ring 27.

[0029] Further, the support seat 3 is slidably mounted on the support arm 2.

[0030] Specifically, by sliding the support seat 3 on the support arm 2, the horizontal distance between the pallet 7 and the hanging rod 1 can be adjusted, thereby facilitating the transfer of metal rings with different diameters.

[0031] Furthermore, a plurality of support arms 2 are circularly distributed, the length direction of the support arms 2 is along the radial direction of the circle where the plurality of support arms 2 are located, the ends of the plurality of support arms 2 are butt-jointed with each other to form a central position, a second threaded rod 21 is screwed and inserted through the central position, and the second threaded rod 21 is locked with the central position through a lock nut 22. A top plate 23 is rotatably arranged at the end of the second threaded rod 21, and a plurality of first connecting arms 24 are inclined and rotatably arranged on the outer wall of the top plate 23. A second connecting arm 25 is horizontally arranged on the side wall of each support seat 3, the second connecting arm 25 slides horizontally on the support arm 2, and the second connecting arm 25 is rotatably connected with the first connecting arm 24.

[0032] Specifically, by rotating the second threaded rod 21, the height position of the top plate 23 can be adjusted, so as to use the first connecting arm 24 and the second connecting arm 25 to pull the support seat 3 to move on the support arm 2, realizing the adjustment of the position of the support seat 3. At the same time, this adjustment method can ensure the synchronous movement of the plurality of support seats 3, so that the center position of the circle where the plurality of support seats 3 are located remains unchanged, which is convenient for limiting the center of gravity position during the transfer of the metal ring 27. The lock nut 22 can lock the second threaded rod 21.

[0033] Furthermore, the hanging rod 1 is connected with each support arm 2 through a pull rope 26, and the lengths of the plurality of pull ropes 26 are equal.

[0034] Specifically, by adopting the connection method of a plurality of equal pull ropes 26, it can be ensured that the plane where the plurality of support arms 2 are located remains horizontal during the transfer, avoiding the inclination of the metal ring 27 caused by the unequal lengths of the plurality of pull ropes 26, and improving the safety of the transfer work.

[0035] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
