Description

Technical Field

[0001] This utility model relates to the field of steel rolling production technology, and more specifically, to a partitioned discharge device for steel rolling furnace exit. Background Technology

[0002] Round steel is a solid, long strip of steel with a circular cross-section. It is primarily produced through a hot-rolling process. A steel billet (usually a small square billet) is heated to a high temperature (typically above 1000°C) and then continuously passed between a series of specially designed rolls. These rolls have circular grooves or are designed to gradually roll the billet into a circular cross-section. The diameter range of round steel is very wide, from very small Φ5.5mm (or even smaller) to Φ300mm or even larger. Different sizes may be produced on different rolling mills (such as wire rod mills, small mills, medium mills, and large mills).

[0003] Common steel rolling furnace discharge devices can only transport round steel. In actual production, round steel bars need to be transported to the rolling mill for processing after exiting the furnace. The steel tapping rhythm of the heating furnace can usually be relatively fast, but the rolling mill takes much longer to roll a steel billet. If the steel billets are continuously exiting the furnace and rushing directly to the rolling mill, the rolling mill cannot process all the steel billets, which will inevitably cause serious blockage and accumulation at the inlet. The accumulation will not only interrupt production, but may also cause equipment damage or safety accidents.

[0004] In summary, in order to ensure continuous and safe production and improve production efficiency, it is necessary to solve the problem of steel billets accumulating and blocking at the entrance of the rolling mill, so that the production rhythm between the heating furnace and the rolling mill can be effectively matched and coordinated. Utility Model Content

[0005] The present invention provides a partitioned discharge device for steel rolling furnace, which aims to solve the problem that the continuous discharge of steel billets directly into the rolling mill will inevitably cause serious blockage and accumulation at the inlet. The accumulation will not only interrupt production, but may also cause equipment damage or safety accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a partitioned discharge device for steel rolling furnace, comprising a fixed plate, a top material plate installed on the upper end of the fixed plate, two lifting grooves equally spaced on the surface of the top material plate, a material holding groove at the upper end of the top material plate, a fixed guide plate installed on the surface of the top material plate, a lifting mechanism provided on the fixed plate, two upward guide plates provided on the lifting mechanism, two material blocking guide plates provided on the lifting mechanism, the material blocking guide plates being slidably connected to the lifting grooves, and an infeed and outfeed conveying mechanism provided on the top material plate and the fixed guide plate.

[0007] In a preferred embodiment, the output end of the lifting mechanism is connected to the upward guide plate and the stop guide plate. The lifting mechanism is used to control the lifting and lowering movement of the upward guide plate and the stop guide plate. The lifting mechanism includes a power component and a limiting component. The output end of the power component is connected to the upward guide plate and the stop guide plate. The power component is used to control the lifting and lowering movement of the upward guide plate and the stop guide plate. The sliding end of the limiting component is connected to the stop guide plate. The limiting component is used to control the stability of the lifting and lowering of the upward guide plate and the stop guide plate.

[0008] In a preferred embodiment, the power assembly includes a cylinder mounted on the upper end of a fixed plate and a lifting bar mounted on the output end of the cylinder. The lower end of the upward push guide plate is connected to the lifting bar, and the end of the baffle guide plate near the upward push guide plate is connected to the lifting bar. The cylinder is used to control the lifting movement of the lifting bar.

[0009] In a preferred embodiment, the limiting component includes a limiting groove formed at the lower end of the baffle guide plate and two limiting rods symmetrically mounted on the upper end of the fixed plate, with the upper ends of the limiting rods inserted into the limiting groove.

[0010] In a preferred embodiment, the feeding and discharging conveying mechanism is used to convey the rolled pieces. The feeding and discharging conveying mechanism includes a feeding component and a discharging component. The discharging end of the feeding component is connected to a fixed guide plate. The feeding component is used to convey the rolled pieces that have just come out of the furnace to the separating discharging structure. The feeding end of the discharging component is connected to a top plate. The discharging component is used to convey individual rolled pieces.

[0011] In a preferred embodiment, the feeding assembly includes a feeding arc plate mounted on the surface of a fixed guide plate, a feeding frame mounted on the end of the feeding arc plate away from the fixed guide plate, and two upward push grooves formed on the surface of the feeding arc plate, wherein the upward push guide plate is slidably connected to the upward push grooves.

[0012] In a preferred embodiment, the discharge assembly includes a discharge arc plate mounted on the surface of the top plate, a discharge frame mounted on the end of the discharge arc plate away from the top plate, and two baffle grooves formed on the surface of the discharge arc plate, with the baffle guide plate slidably connected to the baffle grooves.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention uses a cylinder-driven lifting bar to synchronously drive the upward guide plate and the baffle guide plate to move vertically. The upward inclined groove lifts a single rolled piece to the guide inclined groove at the top of the fixed guide plate. At this time, the baffle guide plate forms a physical barrier to prevent the rolled piece from continuing to roll. After the lifting mechanism descends, the single rolled piece rolls into the holding trough along the inclined groove for temporary storage. Then, the rising baffle guide plate pushes the rolled piece to achieve single-piece release. Attached Figure Description

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual appendix Figures 1 to 6A separate discharge device for steel rolling furnace includes a fixed plate 1, a top material plate 11 installed on the upper end of the fixed plate 1, two lifting grooves 12 equally spaced on the surface of the top material plate 11, a material holding trough 13 at the upper end of the top material plate 11, a fixed guide plate 14 installed on the surface of the top material plate 11, a lifting mechanism provided on the fixed plate 1, two upward guide plates 15 provided on the lifting mechanism, two material blocking guide plates 16 provided on the lifting mechanism, the material blocking guide plates 16 being slidably connected to the lifting grooves 12, and an infeed and outfeed conveying mechanism provided on the top material plate 11 and the fixed guide plate 14.

[0025] It should be noted that the fixed plate 1 serves as the basic support of the device, and the material holding trough 13 of the top plate 11 is used to temporarily store single rolled pieces. The lifting mechanism synchronously drives the upward guide plate 15 and the baffle guide plate 16 to realize the sorting, interception and release of rolled pieces. The baffle guide plate 16 can precisely control the timing of the rolled pieces entering the material holding trough 13 by sliding along the lifting groove 12. The feeding and discharging conveying mechanism is connected with the fixed guide plate 14 and the top plate 11 to form a continuous rolling piece channel.

[0026] It is worth noting that the lifting bar 212 is driven upward by the cylinder 211, and the lifting bar 212 simultaneously drives the upward guide plate 15 and the baffle guide plate 16 to move upward. During this process, the upward guide plate 15 pushes the rolled piece that has rolled from the top of the feed frame 312 upward until the top of the upward guide plate 15 is aligned with the top of the fixed guide plate 14. At this time, the rolled piece rolls to the guide chute 19 by the guide of the upward chute 18. After the rolled piece rolls to the guide chute 19, it is blocked by the baffle guide plate 16, thereby preventing the rolled piece from rolling to the material receiving trough 1. Inside 3, the lifting bar 212 is driven to move downward by the cylinder 211. The lifting bar 212 simultaneously drives the upward guide plate 15 and the baffle guide plate 16 to move downward. At this time, the rolled piece will not be blocked by the baffle guide plate 16, and thus rolls into the inside of the material holding trough 13. When feeding is required, the cylinder 211 drives the baffle guide plate 16 to move upward again through the lifting bar 212. The baffle guide plate 16 pushes the rolled piece inside the material holding trough 13 upward. Then the rolled piece rolls into the inside of the discharge frame 322 through the guide of the feeding arc groove 17.

[0027] Refer to the instruction manual appendix Figures 3 to 4 The output end of the lifting mechanism is connected to the upper guide plate 15 and the stop guide plate 16. The lifting mechanism is used to control the lifting and lowering movement of the upper guide plate 15 and the stop guide plate 16. The lifting mechanism includes a power component and a limiting component. The output end of the power component is connected to the upper guide plate 15 and the stop guide plate 16. The power component is used to control the lifting and lowering movement of the upper guide plate 15 and the stop guide plate 16. The sliding end of the limiting component is connected to the stop guide plate 16. The limiting component is used to control the stability of the lifting and lowering of the upper guide plate 15 and the stop guide plate 16.

[0028] It should be noted that the power component provides the lifting driving force, and the limit component ensures that the push guide plate 15 and the stop guide plate 16 remain vertically synchronized during high-speed lifting by constraining the displacement trajectory of the stop guide plate 16, thus preventing the rolled piece from jamming due to skew.

[0029] Refer to the instruction manual appendix Figures 3 to 4 The power assembly includes a cylinder 211 mounted on the upper end of the fixed plate 1 and a lifting bar 212 mounted on the output end of the cylinder 211. The lower end of the upward guide plate 15 is connected to the lifting bar 212. The end of the baffle guide plate 16 near the upward guide plate 15 is connected to the lifting bar 212. The cylinder 211 is used to control the lifting movement of the lifting bar 212.

[0030] It should be noted that the cylinder 211 drives the lifting bar 212 to move linearly. The lifting bar 212 acts as a common load-bearing beam, so that the upward guide plate 15 and the stop guide plate 16 form a rigid linkage.

[0031] Refer to the instruction manual appendix Figures 3 to 4 The limiting component includes a limiting groove 221 opened at the lower end of the baffle guide plate 16 and two limiting rods 222 symmetrically installed on the upper end of the fixed plate 1. The upper end of the limiting rod 222 is inserted into the interior of the limiting groove 221.

[0032] It should be noted that the limiting rod 222 is inserted into the limiting groove 221 to form a sliding pair, which restricts the degree of freedom of the baffle guide plate 16 in the horizontal direction. The depth of the limiting groove 221 is greater than the lifting stroke to avoid the risk of dislodging.

[0033] Refer to the instruction manual appendix Figures 5 to 6 The feeding and discharging conveying mechanism is used to convey the rolled pieces. The feeding and discharging conveying mechanism includes a feeding component and a discharging component. The discharging end of the feeding component is connected to the fixed guide plate 14. The feeding component is used to convey the rolled pieces that have just come out of the furnace to the separation discharging structure. The feeding end of the discharging component is connected to the top plate 11. The discharging component is used to convey individual rolled pieces.

[0034] It should be noted that the feeding assembly guides the continuous rolled pieces output from the heating furnace to the fixed guide plate 14, where they are sorted by the lifting mechanism. The discharge assembly only transports the rolled piece to the rolling mill after it has fallen into the material trough 13.

[0035] It is worth noting that the feeding and discharging paths are physically isolated by the fixed guide plate 14 and the top plate 11, realizing the process of continuous feeding of rolled pieces to single-piece temporary storage and then sequential discharging, which seamlessly matches the processing rhythm of the rolling mill.

[0036] Refer to the instruction manual appendix Figures 5 to 6The feeding assembly includes a feeding arc plate 311 mounted on the surface of the fixed guide plate 14, a feeding frame 312 mounted on the end of the feeding arc plate 311 away from the fixed guide plate 14, and two upper push grooves 313 formed on the surface of the feeding arc plate 311. The upper push guide plate 15 is slidably connected to the upper push grooves 313.

[0037] It should be noted that the curvature of the feed arc plate 311 matches the rolling trajectory of the workpiece, and the upper push groove 313 allows the upper push guide plate 15 to pass through and slide up and down. When the upper push guide plate 15 rises, its top end extends out from the groove to push the workpiece.

[0038] Refer to the instruction manual appendix Figures 5 to 6 The discharge assembly includes a discharge arc plate 321 installed on the surface of the top plate 11, a discharge frame 322 installed on the end of the discharge arc plate 321 away from the top plate 11, and two baffle grooves 323 formed on the surface of the discharge arc plate 321. The baffle guide plate 16 is slidably connected to the baffle grooves 323.

[0039] It should be noted that when the baffle guide plate 16 rises, its top end extends out from the baffle groove 323, pushing the rolled piece located inside the material holding groove 13 upward. Then, the rolled piece rolls into the interior of the discharge frame 322 through the guide of the feeding arc groove 17.

[0040] Refer to the instruction manual appendix Figures 1 to 6 The upper end of the material guide plate 16 is provided with a feeding arc groove 17, the upper end of the push guide plate 15 is provided with a push inclined groove 18, and the upper end of the fixed guide plate 14 is provided with a guide inclined groove 19.

[0041] It should be noted that the feeding arc groove 17 ensures smooth rolling of the rolled piece, and the upward pushing sloping groove 18 and the guide sloping groove 19 use gravity to assist in the transfer of the rolled piece.

[0042] Working principle: The rolled piece produced by the heating furnace enters the feeding frame 312 and rolls along its surface to the upward push groove 18 of the upward push guide plate 15. At this time, the cylinder 211 drives the lifting bar 212 to move upward, simultaneously driving the upward push guide plate 15 to rise through the upward push groove 313. The upward push groove 18 at its top pushes the rolled piece upward to the top of the fixed guide plate 14. At the same time, the baffle guide plate 16 rises through the baffle groove 323 driven by the lifting bar 212, and its top prevents the rolled piece from entering the holding trough 13. Then the cylinder 211... The lifting bar 212 moves downward, causing the push guide plate 15 and the baffle guide plate 16 to descend synchronously. After the baffle guide plate 16 releases its obstruction, the rolled piece rolls along the guide chute 19 into the material holding trough 13 of the top material plate 11 for temporary storage. When discharge is required, the cylinder 211 drives the lifting bar 212 to rise again, and the feeding arc groove 17 of the baffle guide plate 16 pushes the rolled piece in the material holding trough 13 upward, causing it to roll to the discharge frame 322 and finally be transported to the rolling mill, thereby realizing the rhythm control of the rolled piece from continuous feeding to single piece separation discharge.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
