Description

Technical Field

[0001] The present invention relates to the technical field of steel bar rolling, and particularly relates to a fully automatic steel bar rolling device. Background Art

[0002] Steel bars are a common building and manufacturing material, usually made of steel, with good strength and toughness. Steel bars are usually made of alloy steel or carbon steel, and the specific steel composition and treatment method will affect their performance. The shape of steel bars is generally round or long strip. The rolling of steel bars is mainly carried out by hot rolling. When hot rolling steel bars, the steel bars need to be heated to a certain temperature first, and then the heated steel bars are pushed into the hot rolling mill for hot rolling. The steel bar rolling devices in the prior art usually cannot heat the steel bars, and at the same time, the steel bars need to be manually placed into the rolling mill one by one, and the full-automatic rolling of steel bars cannot be realized. At the same time, the positioning accuracy of the steel bars during the rolling process is relatively low, and the conveying wheels need to be adjusted during the steel bar conveying process, and the conveying wheels cannot automatically cling to the steel bars, resulting in low automation. Summary of the Invention

The feeding device includes a fixed cylinder. The feeding device is used for heating and feeding steel bars. A conveying device is arranged on the feeding device. The conveying device includes a conveying base. The conveying device is used for positioning and conveying steel bars. A rolling roll device is arranged on the conveying device. The rolling roll device includes a rolling seat, and the rolling seat is fixedly installed on the conveying base. The rolling roll device is used for hot rolling steel bars. An unloading device is arranged on the rolling roll device. The unloading device includes an unloading rack, and the unloading rack is fixedly installed on the rolling seat. The unloading device is used for sending out the rolled steel bars.

[0004] Further, the feeding device includes a discharge pipe fixedly installed on the fixed cylinder. A rotating cylinder is rotatably installed on the fixed cylinder. The rotating cylinder is made of quartz glass. A heating coil is arranged outside the rotating cylinder. The heating coil is connected to an external power supply. An inner rotating shaft is fixedly installed on the rotating cylinder. A rotating shaft gear is fixedly installed on the inner rotating shaft. A transmission belt is wound outside the rotating shaft gear. Meshing teeth are arranged on the inner side of the transmission belt. The rotating shaft gear meshes with the inner teeth of the transmission belt, and the transmission belt is elastic.

[0005] Further, eight through holes are arranged on the rotating cylinder. Steel bars are placed in the through holes. The holes above the discharge pipe have the same size as the through holes on the rotating cylinder. When the steel bars reach above the discharge pipe, they will fall into the discharge pipe.

[0006] Eight steel bars are placed in the through holes of the rotating drum. The heating coil heats the steel bars so that they reach the temperature required for hot rolling. The transmission belt drives the rotating shaft gear to rotate, thereby driving the inner rotating shaft and the rotating drum to rotate, and driving the steel bars to rotate. When the steel bars reach the top of the discharge pipe, they fall into the discharge pipe and then reach the bottom support plate.

[0007] Furthermore, the conveying device includes a conveying frame and a bottom support plate fixedly mounted on the conveying base, a conveying motor fixedly mounted on the conveying frame, a motor bevel gear fixedly mounted on the motor shaft of the conveying motor, a top gear shaft rotatably mounted on the conveying frame, a docking bevel gear and an outer bevel gear fixedly mounted on the top gear shaft, the docking bevel gear meshes with the motor bevel gear, a side vertical shaft rotatably mounted on the conveying frame, a side drive wheel and an upper bevel gear fixedly mounted on the side vertical shaft, the upper bevel gear meshes with the outer bevel gear, a middle drive wheel rotatably mounted on the conveying frame, a short drive belt is wrapped around the middle drive wheel and the side drive wheel.

[0008] Furthermore, two clamping mechanisms are provided on the conveying frame, and the clamping mechanism includes a side rotating rod rotatably installed on the conveying frame, the rotation center of the side rotating rod is the same as that of the middle transmission wheel, an outward push roller is rotatably installed on the side rotating rod, a transmission shaft is rotatably installed on the side rotating rod, an outer transmission wheel and a small transmission wheel are fixedly installed on the transmission shaft, an upper transmission belt is wrapped around the outer transmission wheel and the middle transmission wheel, a transmission belt is wrapped around the small transmission wheel and the rotating shaft gear, and the small transmission wheel is meshed with the inner teeth of the transmission belt, a conveying roller frame is fixedly installed on the side rotating rod, a conveying roller is rotatably installed on the conveying roller frame, a conveying gear is fixedly installed on the conveying roller, and an inner transmission wheel is wrapped around the conveying gear and the outer transmission wheel.

[0009] Furthermore, a pressure roller mechanism is provided on the conveying frame, and the pressure roller device includes a side guide column fixedly installed on the side of the conveying frame, a lifting block is slidably installed on the side guide column, a pressure roller is rotatably installed on the lifting block, and a lower spring and an upper spring are provided between the lifting block and the conveying frame.

[0010] When the steel bar falls onto the bottom pallet, it will push the outward pushing roller outwards, and at the same time lift the pressing roller upwards. The outward movement of the outward pushing roller drives the side rotating rod to rotate along the conveying frame, so that the conveying roller frame and the conveying roller move inwards, making the two conveying gears closely adhere to the steel bar. The side guide post makes the pressing roller press the steel bar, and the lower spring provides support to prevent the steel bar from bouncing or jamming during the rolling process. The conveying motor rotates to drive the motor bevel gear to rotate, which drives the top gear shaft and the docking bevel gear to rotate, thereby driving the outer bevel gear to rotate, driving the upper bevel gear and the side vertical shaft to rotate, driving the side transmission wheel to rotate, driving the middle transmission wheel to rotate through the short transmission belt, driving the outer side transmission wheel to rotate through the upper transmission belt, driving the conveying gear and the conveying roller to rotate through the inner transmission wheel, conveying the steel bar towards the rolling seat through the conveying roller, continuously conveying the subsequent arriving steel bars through the conveying roller, continuously pushing the previous steel bar, the rotation of the outer side transmission wheel drives the transmission shaft and the small transmission wheel to rotate, driving the rotating shaft gear to rotate through the transmission belt. Since the transmission belt is provided with internal teeth meshing with the rotating shaft gear and the small transmission wheel, and the transmission belt has a certain elasticity, when the side rotating rod rotates, it will not affect the small transmission wheel driving the rotating shaft gear to rotate through the transmission belt. And because the middle transmission wheel and the rotation center of the side rotating rod are the same, the rotation of the side rotating rod will not affect the middle transmission wheel driving the conveying gear and the conveying roller to rotate.

[0011] Further, the rolling mill device includes upper and lower rolling frames fixedly installed on the rolling seat. Two upper and lower rolling seats are slidably installed on the upper and lower rolling frames. Upper and lower rolling rollers are rotatably installed on the upper and lower rolling seats. Two vertical lead screw shafts are rotatably installed on the upper and lower rolling frames. Upper and lower adjusting disks are fixedly installed on the vertical lead screw shafts. An upper and lower driven wheel is fixedly installed on the other vertical lead screw shaft. An upper and lower transmission belt is wound around the upper and lower driven wheel and the upper and lower adjusting disks. Two sections of threads with opposite thread directions are provided on the vertical lead screw shaft, and the two sections of threads respectively form a threaded drive with the two upper and lower rolling rollers.

[0012] Further, a left - right mechanism is provided on the rolling seat. The left - right mechanism includes left - right rolling frames fixedly installed on the rolling seat. Two horizontal lead screw shafts are rotatably installed on the left - right rolling frames. Two left - right rolling seats are slidably installed on the left - right rolling frames. Left - right rolling rollers are rotatably installed on the left - right rolling seats.

An left - right adjusting disk is fixedly installed on the horizontal lead screw shaft. An left - right driven wheel is fixedly installed on the other horizontal lead screw shaft. An left - right transmission belt is wound around the left - right driven wheel and the left - right adjusting disk.

[0013] By rotating the upper and lower adjustment disks, the upper and lower driven wheels are driven to rotate through the upper and lower transmission belts, thereby driving the rotation of the two vertical lead screw shafts, driving the two upper and lower rolling seats to approach or separate, thereby adjusting the distance between the two upper and lower rolling rolls. Rotating the left and right adjustment disks drives the left and right driven wheels to rotate through the left and right transmission belts, thereby driving the rotation of the two horizontal lead screw shafts, driving the two left and right rolling seats to approach or separate, thereby adjusting the distance between the two left and right rolling rolls, thereby adjusting the size of the steel bar rolling. The conveying roller feeds the steel bar between the upper and lower rolling rolls and then through between the left and right rolling rolls, and the steel bar is rolled by the upper and lower rolling rolls and the left and right rolling rolls.

[0014] Furthermore, the discharging device includes a top-out slope block fixedly installed on the discharging rack, and a sliding slope rack is slidably installed on the discharging rack. A landslide spring is arranged between the sliding slope rack and the discharging rack.

[0015] When the rolling of the steel bar is completed, the steel bar will be continuously pushed forward by the steel bar to be rolled behind. When the steel bar passes through the left and right rolling rolls, it will fall onto the sliding slope rack, driving the sliding slope rack to slide along the discharging rack, and the landslide spring is compressed. When the steel bar contacts the top-out slope block, it will be ejected by the top-out slope block, and the steel bar leaves the sliding slope rack. Subsequently, the landslide spring rebounds back to the initial position.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: (1) The feeding device provided by the present invention can automatically heat the steel bar to the temperature required for hot rolling and automatically and continuously convey the steel bar into the conveying device, with a high degree of automation; (2) The conveying rollers of the conveying device provided by the present invention automatically press against the steel bar under the action of the steel bar pushing the outer pushing roller, making the conveying of the steel bar more reliable.

Detailed implementation manners

[0027] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0028] Example: Refer to Figures 1-9, A fully automatic rolling device for steel bars, including a feeding device. The feeding device includes a fixed cylinder 101. The feeding device is used to heat and feed the steel bars. A conveying device is arranged on the feeding device. The conveying device includes a conveying base 201.

[0029] As Figure 2 , Figure 3 shown, the feeding device includes a discharge pipe 105 fixedly installed on the fixed cylinder 101. A rotating cylinder 103 is rotatably installed on the fixed cylinder 101. The rotating cylinder 103 is made of quartz glass. A heating coil 102 is arranged outside the rotating cylinder 103. The heating coil 102 is connected to an external power supply. An inner rotating shaft 106 is fixedly installed on the rotating cylinder 103. A rotating shaft gear 107 is fixedly installed on the inner rotating shaft 106. A transmission belt 108 is wound outside the rotating shaft gear 107. Meshing teeth are arranged on the inner side of the transmission belt 108. The rotating shaft gear 107 meshes with the inner teeth of the transmission belt 108, and the transmission belt 108 is elastic.

[0030] As Figure 2 , Figure 3 shown, eight through holes are arranged on the rotating cylinder 103. Steel bars 104 are placed in the through holes. The holes above the discharge pipe 105 have the same size as the through holes on the rotating cylinder 103. When the steel bars 104 reach above the discharge pipe 105, they will fall into the discharge pipe 105.

[0031] Eight steel bars 104 are placed in the through holes of the rotating cylinder 103. The heating coil 102 heats the steel bars 104 so that the steel bars 104 reach the temperature required for hot rolling. The transmission belt 108 drives the rotating shaft gear 107 to rotate, thereby driving the inner rotating shaft 106 and the rotating cylinder 103 to rotate, driving the steel bars 104 to rotate. When the steel bars 104 reach above the discharge pipe 105, the steel bars 104 fall into the discharge pipe 105 and then reach the bottom support plate 222.

[0032] As Figures 4-6As shown in the figure, the conveying device includes a conveying frame 202 and a bottom pallet 222 fixedly installed on a conveying base 201. A conveying motor 203 is fixedly installed on the conveying frame 202. A motor bevel gear 204 is fixedly installed on the motor shaft of the conveying motor 203. A top gear shaft 205 is rotatably installed on the conveying frame 202. A docking bevel gear 206 and an outer bevel gear 207 are fixedly installed on the top gear shaft 205. The docking bevel gear 206 meshes with the motor bevel gear 204. A side vertical shaft 211 is rotatably installed on the conveying frame 202. A side transmission wheel 212 and an upper bevel gear 208 are fixedly installed on the side vertical shaft 211. The upper bevel gear 208 meshes with the outer bevel gear 207. A middle transmission wheel 214 is rotatably installed on the conveying frame 202. A short transmission belt 213 is wound around the middle transmission wheel 214 and the side transmission wheel 212.

[0033] As Figures 4-6 shown in the figure, two pressing mechanisms are provided on the conveying frame 202. Each pressing mechanism includes a side rotating rod 220 rotatably installed on the conveying frame 202. The rotation center of the side rotating rod 220 is the same as that of the middle transmission wheel 214. An outer pushing roller 221 is rotatably installed on the side rotating rod 220. A transmission shaft 210 is rotatably installed on the side rotating rod 220. An outer side transmission wheel 216 and a small transmission wheel 209 are fixedly installed on the transmission shaft 210. An upper transmission belt 215 is wound around the outer side transmission wheel 216 and the middle transmission wheel 214. A transmission belt 108 is wound around the small transmission wheel 209 and a rotating shaft gear 107, and the small transmission wheel 209 meshes with the internal teeth of the transmission belt 108. A conveying roller frame 223 is fixedly installed on the side rotating rod 220. A conveying roller 219 is rotatably installed on the conveying roller frame 223. A conveying gear 218 is fixedly installed on the conveying roller 219. An internal transmission wheel 217 is wound around the conveying gear 218 and the outer side transmission wheel 216.

[0034] As Figures 4-6 shown in the figure, a pressing roller mechanism is provided on the conveying frame 202. The pressing roller device includes a side guide post 226 fixedly installed on the side of the conveying frame 202. A lifting block 225 is slidably installed on the side guide post 226. A pressing roller 224 is rotatably installed on the lifting block 225. A lower spring 227 and an upper spring 228 are provided between the lifting block 225 and the conveying frame 202.

[0035] When the steel bar 104 falls onto the bottom pallet 222, it will push the outward pushing roller 221 outwards and simultaneously push the pressing roller 224 upwards. The outward movement of the outward pushing roller 221 drives the side rotating rod 220 to rotate along the conveying frame 202, thereby causing the conveying roller frame 223 and the conveying roller 219 to move inwards, making the two conveying gears 218 closely adhere to the steel bar 104. The side guide post 226 causes the pressing roller 224 to press on the steel bar 104, and the lower spring 227 provides support to prevent the steel bar 104 from bouncing or jamming during the rolling process. The conveying motor 203 rotates to drive the motor bevel gear 204 to rotate, thereby driving the top gear shaft 205 and the docking bevel gear 206 to rotate, thereby driving the outer bevel gear 207 to rotate, thereby driving the upper bevel gear 208 and the side vertical shaft 211 to rotate, thereby driving the side transmission wheel 212 to rotate. The middle transmission wheel 214 is driven to rotate through the short transmission belt 213, the outer side transmission wheel 216 is driven to rotate through the upper transmission belt 215, the conveying gear 218 and the conveying roller 219 are driven to rotate through the inner transmission wheel 217, and the steel bar 104 is conveyed towards the rolling seat 301 through the conveying roller 219. The subsequent arriving steel bars 104 are continuously conveyed through the conveying roller 219, and the previous steel bar 104 will be continuously pushed. The rotation of the outer side transmission wheel 216 drives the transmission shaft 210 and the small transmission wheel 209 to rotate, and the rotating shaft gear 107 is driven to rotate through the transmission belt 108. Since the transmission belt 108 is provided with internal teeth that mesh with the rotating shaft gear 107 and the small transmission wheel 209, and the transmission belt 108 has a certain elasticity, when the side rotating rod 220 rotates, it will not affect the small transmission wheel 209 driving the rotating shaft gear 107 to rotate through the transmission belt 108. And since the middle transmission wheel 214 and the rotation center of the side rotating rod 220 are the same, the rotation of the side rotating rod 220 will not affect the middle transmission wheel 214 driving the conveying gear 218 and the conveying roller 219 to rotate.

[0036] As Figure 7 、 Figure 8 shown, the rolling mill device includes upper and lower rolling frames 302 fixedly installed on the rolling seat 301. Two upper and lower rolling seats 303 are slidably installed on the upper and lower rolling frames 302. Upper and lower rolling rollers 304 are rotatably installed on the upper and lower rolling seats 303. Two vertical lead screw shafts 306 are rotatably installed on the upper and lower rolling frames 302. Upper and lower adjusting disks 307 are fixedly installed on the vertical lead screw shafts 306. An upper and lower driven wheel 309 is fixedly installed on the other vertical lead screw shaft 306. An upper and lower transmission belt 308 is wound around the upper and lower driven wheel 309 and the upper and lower adjusting disks 307. Two sections of threads with opposite thread directions are provided on the vertical lead screw shaft 306, and the two sections of threads respectively form a threaded drive with the two upper and lower rolling rollers 304.

[0037] As Figure 7 、 Figure 8As shown in the figure, a left-right mechanism is provided on the rolling seat 301. The left-right mechanism includes a left-right rolling frame 305 fixedly installed on the rolling seat 301. Two horizontal screw shafts 312 are rotatably installed on the left-right rolling frame 305. Two left-right rolling seats 310 are slidably installed on the left-right rolling frame 305. Left-right rolling rollers 311 are rotatably installed on the left-right rolling seats 310. Two sections of threads with opposite thread directions are provided on the horizontal screw shaft 312. The two sections of threads are respectively in threaded transmission with the two left-right rolling seats 310. A left-right adjusting disc 313 is fixedly installed on the horizontal screw shaft 312. A left-right driven wheel 315 is fixedly installed on the other horizontal screw shaft 312. A left-right transmission belt 314 is wound around the left-right driven wheel 315 and the left-right adjusting disc 313.

[0038] By rotating the up-down adjusting disc 307, the up-down driven wheel 309 is driven to rotate through the up-down transmission belt 308, thereby driving the two vertical screw shafts 306 to rotate, thereby driving the two up-down rolling seats 303 to approach or separate, thereby adjusting the distance between the two up-down rolling rollers 304. Rotating the left-right adjusting disc 313 drives the left-right driven wheel 315 to rotate through the left-right transmission belt 314, thereby driving the two horizontal screw shafts 312 to rotate, thereby driving the two left-right rolling seats 310 to approach or separate, thereby adjusting the distance between the two left-right rolling rollers 311, thereby adjusting the rolling size of the steel bar 104. The conveying roller 219 feeds the steel bar 104 between the up-down rolling rollers 304 and then through between the left-right rolling rollers 311. The steel bar 104 is rolled by the up-down rolling rollers 304 and the left-right rolling rollers 311.

[0039] As Figure 9 shown, the discharging device includes a top-out slope block 402 fixedly installed on the discharging frame 401. A sliding slope frame 403 is slidably installed on the discharging frame 401. A landslide spring 404 is provided between the sliding slope frame 403 and the discharging frame 401.

[0040] When the rolling of the steel bar 104 is completed, it will be continuously pushed forward by the steel bar 104 to be rolled behind. When the steel bar 104 passes through the left-right rolling rollers 311, it will fall onto the sliding slope frame 403, driving the sliding slope frame 403 to slide along the discharging frame 401, and the landslide spring 404 is compressed. When the steel bar 104 contacts the top-out slope block 402, it will be ejected by the top-out slope block 402, and the steel bar 104 leaves the sliding slope frame 403. Subsequently, the landslide spring 404 rebounds to its initial position.

[0041] The working principle of a fully automatic steel bar rolling device disclosed in the present invention is: eight steel bars 104 are placed in the through holes of a rotating drum 103, a heating coil 102 heats the steel bars 104 so that the steel bars 104 reach the temperature required for hot rolling, a transmission belt 108 drives the rotating shaft gear 107 to rotate, thereby driving the inner rotating shaft 106 and the rotating drum 103 to rotate, and driving the steel bars 104 to rotate, and when the steel bars 104 reach above the discharge pipe 105, the steel bars 104 fall into the discharge pipe 105, and then reach the bottom support plate 222. When the steel bar 104 falls onto the bottom support plate 222, the outward push roller 221 will be pushed outward and the pressure roller 224 will be lifted upward. The outward movement of the outward push roller 221 drives the side rotating rod 220 to rotate along the conveying frame 202, so that the conveying roller frame 223 and the conveying roller 219 move inward, so that the two conveying gears 218 are close to the steel bar 104, and the side guide column 226 makes the pressure roller 224 press the steel bar 104. The lower spring 227 provides support to prevent the steel bar 104 from bouncing or getting stuck during the rolling process. The conveying motor 203 rotates to drive the motor bevel gear 204 to rotate, thereby driving the top gear shaft 205 and the docking bevel gear 206 to rotate, thereby driving the outer bevel gear 207 to rotate, thereby driving the upper bevel gear 208 and the side vertical shaft 211 to rotate, thereby driving the side transmission wheel 212 to rotate, driving the middle transmission wheel 214 to rotate through the short transmission belt 213, and driving the outer transmission wheel through the upper transmission belt 215 216 rotates, and drives the conveying gear 218 and the conveying roller 219 to rotate through the inner transmission wheel 217, and conveys the steel bar 104 toward the rolling seat 301 through the conveying roller 219, and continuously conveys the subsequent steel bar 104 through the conveying roller 219, which will continuously push the front steel bar 104, and the rotation of the outer transmission wheel 216 will drive the transmission shaft 210 and the small transmission wheel 209 to rotate, and drive the rotating shaft gear 107 to rotate through the transmission belt 108. Since the transmission belt 108 is provided with internal teeth that mesh with the rotating shaft gear 107 and the small transmission wheel 209, and the transmission belt 108 has a certain elasticity, when the side rotating rod 220 rotates, it will not affect the small transmission wheel 209 to drive the rotating shaft gear 107 to rotate through the transmission belt 108, and since the middle transmission wheel 214 and the side rotating rod 220 have the same rotation center, the rotation of the side rotating rod 220 will not affect the middle transmission wheel 214 to drive the conveying gear 218 and the conveying roller 219 to rotate.By rotating the upper and lower adjusting disc 307, the upper and lower driven wheels 309 are driven to rotate through the upper and lower transmission belts 308, thereby driving the rotation of the two vertical lead screw shafts 306, driving the two upper and lower rolling seats 303 to approach or move away from each other, thereby adjusting the distance between the two upper and lower rolling rolls 304. By rotating the left and right adjusting disc 313, the left and right driven wheels 315 are driven to rotate through the left and right transmission belts 314, thereby driving the rotation of the two horizontal lead screw shafts 312, driving the two left and right rolling seats 310 to approach or move away from each other, thereby adjusting the distance between the two left and right rolling rolls 311, and thus adjusting the size of the steel bar 104 during rolling. The conveying roller 219 feeds the steel bar 104 between the upper and lower rolling rolls 304 and then through between the left and right rolling rolls 311, and the steel bar 104 is rolled by the upper and lower rolling rolls 304 and the left and right rolling rolls 311. When the rolling of the steel bar 104 is completed, it will be continuously pushed forward by the steel bar 104 to be rolled behind. When the steel bar 104 passes through the left and right rolling rolls 311, it will fall onto the sliding slope frame 403, driving the sliding slope frame 403 to slide along the discharging frame 401, and the landslide spring 404 is compressed.
