Description

Technical Field

[0001] The invention relates to the technical field of steel bar rolling, and in particular 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 processing methods will affect its performance. The shape of steel bars is generally round or long. The rolling of steel bars is mainly carried out by hot rolling. When hot rolling, 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 device in the prior art is usually unable to heat the steel bars, and needs to be manually placed into the rolling mill one by one, and it is impossible to achieve fully automatic rolling of steel bars. At the same time, the positioning accuracy of the steel bars during the rolling process is low, and the conveying wheel needs to be adjusted during the steel bar conveying process. The conveying wheel cannot automatically stick to the steel bar, and the degree of automation is low. Summary of the invention

When the steel bar reaches above the discharge pipe, it 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.

By rotating the left and right adjusting disks, the left and right driven wheels are driven to rotate through the left and right transmission belts, thereby driving the two horizontal screw shafts to rotate, thereby driving the two left and right rolling seats to move closer or farther away, thereby adjusting the distance between the two left and right rolling rollers, thereby adjusting the size of the rolled steel bar. The conveying rollers pass the steel bar between the upper and lower rolling rollers and the left and right rolling rollers, and the steel bar is rolled by the upper and lower rolling rollers and the left and right rolling rollers.

[0014] Furthermore, the discharging device comprises a top slope block fixedly mounted on the discharging rack, a sliding slope rack is slidably mounted on the discharging rack, and a sliding slope spring is arranged between the sliding slope rack and the discharging rack.

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 drum 103 to rotate, and driving the steel bars 104 to rotate. When the steel bars 104 reach the top of the discharge pipe 105, the steel bars 104 fall into the discharge pipe 105 and then reach the bottom support plate 222.

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

[0033] like Figure 4-Figure 6 As shown, two pressing mechanisms are arranged on the conveying frame 202, and the pressing mechanism includes a side rotating rod 220 rotatably mounted on the conveying frame 202, and the rotation center of the side rotating rod 220 is the same as that of the middle transmission wheel 214. An outward push roller 221 is rotatably mounted on the side rotating rod 220, and a transmission shaft 210 is rotatably mounted on the side rotating rod 220. An outer transmission wheel 216 and a small transmission wheel 209 are fixedly mounted on the transmission shaft 210. An upper transmission belt 215 is wound around the outer transmission wheel 216 and the middle transmission wheel 214, and a transmission belt 108 is wound around the small transmission wheel 209 and the rotating shaft gear 107, and the small transmission wheel 209 is meshed with the inner teeth of the transmission belt 108.

A conveying gear 218 is fixedly mounted on the conveying roller 219, and an inner transmission wheel 217 is wound around the conveying gear 218 and the outer transmission wheel 216.

[0034] like Figure 4-Figure 6 As shown, a pressure roller mechanism is provided on the conveying frame 202, and the pressure roller device includes a side guide column 226 fixedly installed on the side of the conveying frame 202, a lifting block 225 is slidably installed on the side guide column 226, a pressure roller 224 is rotatably installed on the lifting block 225, and 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 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.

[0036] like Figure 7 , Figure 8 As shown, the rolling device includes an upper and lower rolling frame 302 fixedly mounted on a rolling seat 301, two upper and lower rolling seats 303 are slidably mounted on the upper and lower rolling frames 302, upper and lower rolling rollers 304 are rotatably mounted on the upper and lower rolling seats 303, two vertical screw shafts 306 are rotatably mounted on the upper and lower rolling frames 302, upper and lower adjusting disks 307 are fixedly mounted on the vertical screw shafts 306, and upper and lower driven wheels 309 are fixedly mounted on the other vertical screw shaft 306.

[0037] like Figure 7 , Figure 8As shown, a left and right mechanism is arranged on the rolling seat 301, and the left and right mechanism includes a left and right rolling stand 305 fixedly mounted on the rolling seat 301, two horizontal screw shafts 312 are rotatably mounted on the left and right rolling stands 305, two left and right rolling stands 310 are slidably mounted on the left and right rolling stands 305, left and right rolling rollers 311 are rotatably mounted on the left and right rolling stands 310, two sections of threads with opposite thread directions are arranged on the horizontal screw shaft 312, and the two sections of threads respectively form thread transmission with the two left and right rolling stands 310, left and right adjusting disks 313 are fixedly mounted on the horizontal screw shaft 312, and left and right driven wheels 315 are fixedly mounted on another horizontal screw shaft 312, and left and right transmission belts 314 are wound around the left and right driven wheels 315 and the left and right adjusting disks 313.

[0038] By rotating the upper and lower adjustment disks 307, the upper and lower driven wheels 309 are driven to rotate through the upper and lower transmission belts 308, thereby driving the two vertical screw shafts 306 to rotate, thereby driving the two upper and lower rolling seats 303 to move closer or farther away, thereby adjusting the distance between the two upper and lower rolling rollers 304. By rotating the left and right adjustment disks 313, the left and right driven wheels 315 are driven to rotate through the left and right transmission belts 314, thereby driving the two horizontal screw shafts 312 to rotate, thereby driving the two left and right rolling seats 310 to move closer or farther away, thereby adjusting the distance between the two left and right rolling rollers 311, thereby adjusting the size of the rolled steel bar 104. The conveying roller 219 passes the steel bar 104 between the upper and lower rolling rollers 304 and then passes it between the left and right rolling rollers 311, and rolls the steel bar 104 through the upper and lower rolling rollers 304 and the left and right rolling rollers 311.

[0039] like Fig. 9 As shown, the discharging device includes a top slope block 402 fixedly mounted on a discharging frame 401 , a sliding slope frame 403 is slidably mounted on the discharging frame 401 , and a sliding slope spring 404 is provided between the sliding slope frame 403 and the discharging frame 401 .

[0040] When the rolling is completed, the steel bar 104 will be continuously pushed forward by the steel bar 104 to be rolled at the rear. After the steel bar 104 passes through the left and right rollers 311, it will fall onto the sliding ramp 403, driving the sliding ramp 403 to slide along the discharge rack 401, and the sliding spring 404 will be compressed. When the steel bar 104 contacts the ejection ramp block 402, it will be ejected by the ejection ramp block 402, and the steel bar 104 will leave the sliding ramp 403, and then the sliding spring 404 will rebound 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 adjustment disks 307, the upper and lower driven wheels 309 are driven to rotate through the upper and lower transmission belts 308, thereby driving the two vertical screw shafts 306 to rotate, thereby driving the two upper and lower rolling seats 303 to move closer or farther away, thereby adjusting the distance between the two upper and lower rolling rollers 304. By rotating the left and right adjustment disks 313, the left and right driven wheels 315 are driven to rotate through the left and right transmission belts 314, thereby driving the two horizontal screw shafts 312 to rotate, thereby driving the two left and right rolling seats 310 to move closer or farther away, thereby adjusting the distance between the two left and right rolling rollers 311, thereby adjusting the size of the rolled steel bar 104. The conveying roller 219 passes the steel bar 104 between the upper and lower rolling rollers 304 and then passes it between the left and right rolling rollers 311, and rolls the steel bar 104 through the upper and lower rolling rollers 304 and the left and right rolling rollers 311. When the rolling is completed, the steel bar 104 will be continuously pushed forward by the steel bar 104 to be rolled at the rear. After the steel bar 104 passes through the left and right rollers 311, it will fall onto the sliding ramp 403, driving the sliding ramp 403 to slide along the discharge rack 401, and the sliding spring 404 will be compressed. When the steel bar 104 contacts the ejection ramp block 402, it will be ejected by the ejection ramp block 402, and the steel bar 104 will leave the sliding ramp 403, and then the sliding spring 404 will rebound to its initial position.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the protection scope of the present invention.
