Description

Technical Field

[0001] This utility model relates to the technical field of rebar production equipment, and in particular to a steel billet unloading and steel transfer device. Background Technology

[0002] In the production process of rebar, steel billets are usually transported to the unloading platform using conveyor rollers. The steel billets are then pulled onto the unloading platform by a steel transfer device on the rollers. Nowadays, steel rolling mills mainly use a drive cylinder to push them. Large, front-mounted drive cylinders are commonly used on-site. These cylinders experience significant wear and require the billet to be pushed and reset before the next billet can be conveyed. Furthermore, the drive cylinder and the billet are prone to interference, which further reduces the lifespan of the equipment. Utility Model Content

[0003] The purpose of this utility model is to provide a steel billet unloading and steel transfer device, which facilitates the pushing of steel billets by pushing them with push blocks and can also realize the automatic retraction of push blocks. Subsequent steel billets do not need to wait; they can be transported first and then pushed after the push blocks are reset and pushed, thereby improving the fault tolerance rate and service life of the device.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A steel billet unloading and steel moving device includes a push rod assembly. One end of the push rod assembly is connected to a driving device, and the other end is connected to a stop device. The stop device pushes the steel billet, and the driving device drives the push rod assembly to move axially. The stop device includes a thrust block and a stop block. The thrust block is hinged to the push rod assembly and includes a weight at the lower end of the hinge shaft and a push block at the upper end of the hinge shaft. The rotational position of the thrust block includes pushing and yielding. The stop block is located outside the weight block. The thrust block rotates to the push position under its own weight. The weight block in the push position abuts against the stop block, while the push block is blocked on the movement path of the steel billet. The steel billet in the direction of the push block pushes the thrust block to rotate to the yield position, and the yielded push block leaves the movement path of the steel billet.

[0005] By adopting the above technical solution, the thrust block rotates to the push position under its own weight. The weight of the push position abuts against the stop block, and the push block is blocked on the movement path of the steel billet. This facilitates pushing the steel billet and completing the material feeding by pushing the push block. At the same time, when there is a steel billet inside the push block, it can push the thrust block to rotate to the yield position. The yielded push block leaves the movement path of the steel billet, realizing the automatic retraction of the push block. This allows the steel billets that are subsequently transported to be transported first without waiting, and then pushed once the push block is reset. This improves the fault tolerance and service life of the device.

[0006] Furthermore, an inclined surface is provided on the upper inner side of the push block, and the steel billet in the inner direction of the push block pushes the thrust block to rotate to the desired position through the inclined surface.

[0007] By adopting the above technical solution, the pusher block is easily retracted under the action of the steel billet, saving equipment materials.

[0008] Furthermore, the driving device includes a rotating base, on which a rotating long shaft is rotatably connected. A connecting shaft is hinged to the outer end of the rotating long shaft, and the other end of the connecting shaft is hinged to a push rod assembly. The rotating long shaft is connected to a power source, and the power source drives the rotating long shaft to rotate actively.

[0009] By adopting the above technical solution, the power source drives the rotating long shaft to rotate actively, thereby driving the push rod assembly to move axially through the connecting shaft.

[0010] Furthermore, the power source includes a fixed base, on which a drive cylinder is rotatably connected, and the output end of the drive cylinder is hinged to the free end of the rotating long shaft.

[0011] By adopting the above technical solution, the output end of the drive cylinder is hinged to the free end of the rotating long shaft, thereby realizing the active rotation of the rotating long shaft.

[0012] Furthermore, the rotating base is also connected to a limiting component that restricts the path of the long axis of rotation.

[0013] By adopting the above technical solution, the rotation path of the rotating long shaft is restricted, thereby achieving its accurate movement.

[0014] Furthermore, the limiting component includes a limiting arc groove, a limiting shaft is fixed on the rotating long shaft, and the outer end of the limiting shaft is connected to a limiting block located in the limiting arc groove. The rotation of the rotating long shaft causes the limiting block to move within the limiting arc groove.

[0015] By adopting the above technical solution, the rotation of the long shaft drives the limiting block to move within the limiting arc groove, thereby restricting the movement path of the long shaft.

[0016] Furthermore, it also includes a guide device, which guides the axial movement of the guide push rod assembly.

[0017] By adopting the above technical solution, the axial movement of the guide push rod assembly of the guide device is improved in terms of accuracy and stability.

[0018] Furthermore, the guiding device includes a plurality of rollers abutting against the upper and lower sides of the push rod assembly.

[0019] By adopting the above technical solution, multiple rollers abut against the upper and lower sides of the push rod assembly to achieve its guiding function.

[0020] In summary, this utility model has the following beneficial effects: The thrust block rotates to the push position under its own weight. The weight of the push position abuts against the stop block, and the push block is positioned on the movement path of the steel billet. This facilitates pushing the steel billet and completing the material feeding by pushing the push block. At the same time, when there is a steel billet inside the push block, it can push the thrust block to rotate to the yield position. The yielded push block leaves the movement path of the steel billet, realizing the automatic retraction of the push block. This allows the steel billets that are subsequently delivered to be delivered first without waiting, and then pushed once the push block is reset, which improves the fault tolerance and service life of the device. The output end of the drive cylinder is hinged to the free end of the rotating shaft, enabling the active rotation of the rotating shaft. This, in turn, drives the push rod assembly to move axially via the connecting shaft. The limiting assembly restricts the rotation path of the rotating shaft, thus achieving accurate and stable pushing operation. Attached Figure Description

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation on this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0025] A steel billet unloading and steel transfer device, such as Figure 1 As shown, it includes a push rod assembly 5 and a guide device 4. One end of the push rod assembly 5 is connected to a drive device, and the other end is connected to a backstop device 8. The backstop device 8 pushes the steel billet 6, and the drive device drives the push rod assembly 5 to move axially. Among them, such as Figure 2As shown, the push rod assembly 5 moves axially through the guidance of the guide device 4. The guide device 4 includes a body, and a number of rollers 7 are symmetrically arranged and abut against the upper and lower sides of the push rod assembly 5. The outer circumferential surface of the rollers 7 can be V-shaped or arc-shaped to match the push rod assembly 5.

[0026] like Figure 1 As shown, the driving device includes a rotating base, on which a rotating long shaft 3 is rotatably connected. A connecting shaft is hinged to the outer end of the rotating long shaft 3, and the other end of the connecting shaft is hinged to a push rod assembly 5. The rotating long shaft 3 is connected to a power source, which drives the rotating long shaft 3 to rotate actively. The power source can be a rotary drive structure such as a motor. In this embodiment, the power source includes a fixed base, on which a drive cylinder 1 (hydraulic cylinder or electric cylinder, etc.) is rotatably connected. The output end of the drive cylinder 1 is hinged to the free end of the rotating long shaft 3. The rotation of the rotating long shaft 3 is driven by the extension and retraction of the drive cylinder 1. In this embodiment, the hinge point of the output end of the drive cylinder 1, the rotating long shaft 3, and the connecting shaft is the same, and they can be connected by a pin or the like and easily disassembled.

[0027] like Figure 1 As shown, a limiting component that restricts the path of the rotating long shaft 3 is also connected to the rotating base. The limiting component includes a fixed plate welded to the rotating base and a limiting arc groove 2 opened in the fixed plate. A limiting shaft (screw) is fixed on the rotating long shaft 3. The outer end of the limiting shaft is connected to a limiting block located in the limiting arc groove 2. The rotation of the rotating long shaft 3 drives the limiting block to move in the limiting arc groove 2. The inner end of the limiting shaft is fixed at the rotation center position of the rotating long shaft 3. The limiting arc groove 2 is coaxially set with the rotation center of the rotating long shaft 3 to realize the rotation limit. It can also replace or add a corresponding proximity switch, etc., to realize the extension and retraction limit of the drive cylinder 1, which is convenient for adjustment.

[0028] like Figure 1 and Figure 3 As shown, the anti-reverse device 8 includes a thrust block and a stop block 10. A pin 9 is connected to the middle of the thrust block, and the thrust block is hinged to the push rod assembly 5 around the pin 9. The pin 9 is easily disassembled to replace the thrust block, which can be replaced by a rotating shaft assembly or other fixed rotating mechanism. The thrust block includes a weight at the lower end of the hinge shaft (pin 9) and a push block at the upper end of the hinge shaft. The weight and push block are integrally connected. The rotational positions of the thrust block include pushing and yielding. The stop block 10 is located outside the weight block and welded to the push rod assembly 5. The thrust block rotates to the push position under its own weight. The weight block in the push position abuts against the inside of the stop block 10, and the push block is blocked on the moving path of the steel billet 6 to push the steel billet 6 in front. The steel billet 6 in the direction of the push block pushes the thrust block to rotate to the yield position (clockwise rotation). The yielded weight block leaves the stop block 10 and the push block leaves the moving path of the steel billet 6 to go around the steel billet 6 behind and move to its rear. Finally, the push block resets under its own weight and pushes the corresponding steel billet 6 forward. In this embodiment, an inclined surface is opened at the upper end of the inner (rear) side of the push block. The steel billet 6 in the direction of the inner side of the push block pushes the thrust block to rotate to the yield position through the inclined surface.

[0029] When the billet 6 passes through the conveyor roller and stops, the output end of the drive cylinder 1 extends, driving the rotating long shaft 3 to rotate. The rotating long shaft 3 drives the connecting shaft and the push rod assembly 5 to extend forward. At this time, the thrust block rotates to the push position under its own weight. The weight of the push position abuts against the stop block 10, and the push block is blocked on the moving path of the billet 6. As the push rod assembly 5 pushes the billet 6 forward to the furnace or the designated position, the drive cylinder 1 retracts and the push rod assembly 5 resets. During the reset process, if there is a steel billet 6 inside the push block, the steel billet 6 pushes the thrust block to rotate to the clearance position. The clearance push block leaves the movement path of the steel billet 6, realizing the automatic retraction of the push block. This allows the steel billet 6 that is subsequently delivered to not have to wait. It can be delivered first, and then pushed once after the push block is retracted and reset, which improves the fault tolerance and service life of the device.
