A billet transfer device

Abstract

This invention discloses a billet transfer device, including a drive mechanism for providing pushing force during billet transfer, a frame, and a transmission mechanism for conveying the billet. The drive mechanism passes through the middle of the frame, and the transmission mechanism is located on both sides of the upper end of the frame. This invention utilizes the rotation of the transfer frame to drive a first and second pusher frame towards the middle of the conveyor roller sleeve via a transfer gear. Then, a tapered seat pushes the ejector frame inside the conveyor roller sleeve outwards, and the ejector frame pushes steel balls outwards from the outside of the conveyor roller sleeve to lift the billet. This reduces the friction between the billet and the conveyor roller sleeve during transfer. By using steel balls to lift the billet and reduce friction, the transfer frame experiences less force when pushing the billet, thus allowing for more effortless billet transfer.

Description

Technical Field

[0001] This invention relates to the field of metal casting production, and in particular to a billet transfer device. Background Technology

[0002] The production process of continuously casting molten steel at high temperatures into billets with specific cross-sectional shapes and dimensions is called continuous steel casting. The equipment required to complete this process is called a complete set of continuous casting equipment. The electromechanical-hydraulic integration of the steel casting equipment, the continuous casting machine body, the cutting area equipment, and the dummy bar collection and conveying equipment constitutes the core equipment of continuous steel casting, which is conventionally referred to as a continuous casting machine. A search of patent document CN 113263153 A reveals "a billet transfer device on a continuous casting production line, including a roller conveyor with conveying rollers, and several support rods. A single support rod is positioned between two conveying rollers of the roller conveyor. A first support and a second support are positioned below the support rod. A rotatable first support shaft is mounted on the first support, and a first connecting rod is mounted on the first support shaft. The first connecting rod is rotatably connected to the first support side of the support rod. A rotatable second support shaft is mounted on the second support, and a second connecting rod is mounted on the second support shaft." The connecting rod is connected to the second support side of the support rod. The first connecting rod is parallel to the second connecting rod, and the rotation distance between the first support shaft and the first connecting rod connecting the support rod is equal to the rotation distance between the second support shaft and the second connecting rod connecting the support rod. A drive device is provided to control the rotation of the second support shaft. In this patent, multiple support seats are used to lift the billet and push it outward. In this process, the billet needs to be fully lifted before it is pushed. During this process, there will be friction between the billet and the support seats. When the pushing is about to be completed, the friction may cause the billet to be driven back, which is very dangerous. Summary of the Invention

[0003] The purpose of this invention is to provide a billet transfer device in order to solve the above-mentioned problems.

[0004] The present invention achieves the above objectives through the following technical solutions: A billet transfer device includes a drive mechanism for providing pushing force during billet transfer, a frame, and a transmission mechanism for conveying the billet. The drive mechanism passes through the middle of the frame, and the transmission mechanism is located on both sides of the upper end of the frame. It also includes a conveying mechanism for reducing the friction of the billet during transfer and a transfer mechanism for pushing the billet during transfer. The conveying mechanism is located at the upper end of the frame, and the transfer mechanism is located inside the frame below the conveying mechanism.

[0005] Preferably, the conveying mechanism includes a conveying roller sleeve, a conical seat, a support frame, an ejector frame, and a return spring. Two of the support frames are fixed inside the conveying roller sleeve on both sides. One end of the support frame extending out of the conveying roller sleeve is rotatably connected to the frame. The conical seat is sleeved outside the support frame and located at the end of the conveying roller sleeve. Eight ejector frames are arranged in a ring-like structure inside the conveying roller sleeve. The return spring is fixed at one end of the conical seat near the conveying roller sleeve.

[0006] Preferably, the conveying mechanism further includes steel balls, and the inside of the conveying roller sleeve is provided with a guide groove for the movement of the ejector frame at the end position of the ejector frame. The steel balls are located between the ejector frame and the conveying roller sleeve. The outside of the conveying roller sleeve is provided with a rolling hole corresponding to the steel balls. The contact position between the steel balls and the ejector frame is provided with a groove for fixing the steel balls, and the steel balls are nested in the rolling hole of the conveying roller sleeve.

[0007] Preferably, the drive mechanism includes a drive hydraulic rod, a drive rack, a drive gear, and a drive fixing frame. The drive fixing frame is fixed on the frame. The fixed part of the drive hydraulic rod is bolted to one side of the drive fixing frame. The drive rack is fixed to the telescopic part of the drive hydraulic rod, and the lower end of the drive rack is slidably connected to a groove opened in the drive fixing frame. The drive gear is connected to the transfer mechanism and meshes with the drive rack.

[0008] Preferably, the transfer mechanism includes a transfer frame, a transfer gear, a first pusher frame, and a second pusher frame. The transfer frame passes through the interior of the frame. The first pusher frame and the second pusher frame are respectively located on the conical seats at both ends of the conveying roller sleeve, and the first pusher frame is located on one side of the second pusher frame.

[0009] Preferably, the transfer frame has two push rods welded to the inner side of the frame, and the two push rods are respectively located on both sides of the conveying roller sleeve. The transfer gear is provided between the two push rods of the transfer frame, and the first push frame and the second push frame have teeth that mesh with the transfer gear at the ends near the transfer gear.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The rotation of the transfer frame drives the first and second push frames to move towards the middle position of the conveying roller sleeve through the transfer gear. Then, the ejector frame inside the conveying roller sleeve is pushed outward through the conical seat. The ejector frame then pushes the steel balls outward through the outside of the conveying roller sleeve to lift the billet. This reduces the friction between the billet and the conveying roller sleeve during the transfer process. 2. By using steel balls to lift the billet, the friction is reduced, which reduces the force on the billet when the transfer frame pushes it, thus making it easier to transfer the billet.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-8 As shown, a billet transfer device includes a drive mechanism 3 for providing pushing force during billet transfer, a frame 4, and a transmission mechanism 5 for conveying the billet. The drive mechanism 3 passes through the middle of the frame 4, and the transmission mechanism 5 is located on both sides of the upper end of the frame 4. It also includes a conveying mechanism 1 for reducing the friction of the billet during billet transfer and a transfer mechanism 2 for pushing the billet during transfer. The conveying mechanism 1 is located at the upper end of the frame 4, and the transfer mechanism 2 is located inside the frame 4 below the conveying mechanism 1.

[0017] In this embodiment: the drive mechanism 3 includes a drive hydraulic rod 31, a drive rack 32, a drive gear 33, and a drive fixing frame 34. The drive fixing frame 34 is fixed on the frame 4. The fixed part of the drive hydraulic rod 31 is bolted to one side of the drive fixing frame 34. The drive rack 32 is fixed to the telescopic part of the drive hydraulic rod 31, and the lower end of the drive rack 32 is slidably connected in a groove opened for it in the drive fixing frame 34. The drive gear 33 is connected to the transfer mechanism 2 and meshes with the drive rack 32. The telescopic part of the drive hydraulic rod 31 pushes the drive rack 32 to move in the groove of the drive fixing frame 34. The movement of the drive rack 32 drives the drive gear 33 to rotate, and then the drive gear 33 drives the transfer mechanism 2 to perform a flipping and conveying action.

[0018] In this embodiment: the conveying mechanism 1 includes a conveying roller sleeve 11, a conical seat 12, a support frame 13, an ejector frame 14, steel balls 15, and a return spring 16. Two support frames 13 are fixed inside the conveying roller sleeve 11 on both sides. One end of the support frame 13 extending out of the conveying roller sleeve 11 is rotatably connected to the frame 4. The conical seat 12 is sleeved on the outside of the support frame 13 and located at the end of the conveying roller sleeve 11. Eight ejector frames 14 are arranged in a ring structure inside the conveying roller sleeve 11. A return spring 16 is fixed at the end of the conical seat 12 near the conveying roller sleeve 11. A guide groove for the movement of the ejector frame 14 is opened inside the conveying roller sleeve 11 at the end of the ejector frame 14. The steel balls 15 are located at the ejector... Between the frame 14 and the conveying roller sleeve 11, the outer side of the conveying roller sleeve 11 is provided with a rolling hole corresponding to the steel ball 15. The contact position between the steel ball 15 and the ejector frame 14 is provided with a groove for fixing the steel ball 15, and the steel ball 15 is nested in the rolling hole of the conveying roller sleeve 11. The support frame 13 at both ends of the conveying roller sleeve 11 is used to support it. At the same time, the movement of the conical seat 12 on the support frame 13 is used to push the ejector frame 14 to move outward of the conveying roller sleeve 11, thereby ejecting the steel ball 15 at the upper end of the ejector frame 14 out of the rolling hole of the conveying roller sleeve 11. Then, the steel ball 15 is used to lift the billet, thereby reducing the friction between the billet and the conveying roller sleeve 11 during the transfer process.

[0019] In this embodiment: the transfer mechanism 2 includes a transfer frame 21, a transfer gear 22, a first pusher frame 23, and a second pusher frame 24. The transfer frame 21 penetrates the interior of the frame 4. The first pusher frame 23 and the second pusher frame 24 are respectively located on the conical seats 12 at both ends of the conveyor roller sleeve 11. The first pusher frame 23 is located on one side of the second pusher frame 24. Two push rods are welded to the inner side of the transfer frame 21, and the two push rods are respectively located on both sides of the conveyor roller sleeve 11. A transfer gear 22 is provided between the two push rods of the transfer frame 21. The first pusher frame 23 and the second pusher frame 24... The pusher 24 has teeth that mesh with the transfer gear 22 at one end. The rotation of the drive gear 33 drives the transfer frame 21 to rotate inside the frame 4. Then, the push rod on the transfer frame 21 pushes the billet on the conveying roller sleeve 11 to move. At the same time, as the transfer frame 21 rotates, the transfer gear 22 drives the first pusher 23 and the second pusher 24 to move towards the middle position. Then, the first pusher 23 and the second pusher 24 drive the ends of the conical seats 12 on both sides of the conveying roller sleeve 11 to extend into the conveying roller sleeve 11.

[0020] In this embodiment, the transmission mechanism 5 includes a geared motor 51, a pulley 52, and a belt 53. The geared motor 51 is bolted to one side of the frame 4. The rotating part of the geared motor 51 is connected to the support frame 13 at one end of the conveying roller sleeve 11. The pulley 52 is mounted on the support frame 13 at the other end of the conveying roller sleeve 11. The rotating part of the geared motor 51 drives the support frame 13 on one side of the conveying roller sleeve 11 to rotate. The transmission of the conveying roller sleeve 11 drives the support frame 13 on the other side to rotate as well. Then, the transmission of the pulley 52 and the belt 53 drives multiple conveying roller sleeves 11 to rotate synchronously, thereby completing the process of conveying the billet.

[0021] Working principle: In use, the rotating part of the reduction motor 51 first drives the connected support frame 13 to rotate. The support frame 13 drives the conveying roller sleeve 11 and the support frame 13 at its other end to rotate. At the same time, the transmission action of the pulley 52 and belt 53 drives multiple conveying roller sleeves 11 to rotate synchronously, thereby completing the conveying process of the billet. When the billet is transferred, the extension part of the drive hydraulic rod 31 pushes the drive rack 32 to move in the slide groove of the drive fixed frame 34. Then the drive gear 33 meshing with the drive rack 32 starts to rotate. Then the transfer frame 21 starts to rotate under the drive of the drive gear 33. At this time, the push rod on the outside of the transfer frame 21 starts to flip. At the same time, the transfer gear 22 on the transfer frame 21 drives the first push frame 23 and the second push frame 24 to move to the middle position at the same time. Then the first push frame 23 and the second push frame 24 drive the conical seat 12 on the support frame 13 to move towards the conveying roller sleeve 11 at the same time. The support 12 pushes the ejector 14 inside the conveyor roller sleeve 11 outward. Then, the steel ball 15 between the ejector 14 and the conveyor roller sleeve 11 is ejected from the rolling hole of the conveyor roller sleeve 11, and the billet is lifted by the steel ball 15. The billet can then easily move on the upper side of the conveyor roller sleeve 11. As the transfer frame 21 rotates, the transfer gear 22 completely disengages from the teeth of the first pusher 23 and the second pusher 24, and simultaneously, the push rod of the transfer frame 21 abuts against... On one side of the billet, the billet is then transferred. After the transfer is completed, the driving hydraulic rod 31 drives the driving rack 32 to retract, and at the same time the driving gear 33 rotates in the opposite direction to the transfer frame 21. The push rod on the outside of the transfer frame 21 is reset in the opposite direction. In addition, the elastic force of the reset spring 16 is used to make the teeth of the second push frame 24 and the first push frame 23 mesh with the transfer gear 22 through the conical seat 12. Then the steel ball 15 that extends outward will follow the ejector frame 14 and fall into the inside of the conveying roller sleeve 11.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
