Description

Technical Field

[0001] The present invention belongs to the technical field of steel bar processing, and in particular relates to an intelligent steel bar sawing, threading and grinding device. Background Art

[0002] Rebar threading refers to the process of machining external threads on the ends of rebars using mechanical equipment. Its core purpose is to achieve reliable connection of rebars through thread engagement, thereby replacing traditional welding or binding methods and improving construction efficiency and structural safety.

[0003] Traditionally, when threading rebar, the long strips are usually cut into the required length and then manually transferred to a threading machine. One end of the rebar is first threaded, and then the rebar is turned and the other end is threaded. After the rebar is threaded, it is manually transferred to a grinder to grind each end separately. This method is time-consuming and labor-intensive, with high labor costs, low work efficiency, and safety risks.

During transport, the piston rod of the electric cylinder 5322 extends, driving the receiving member 5324 upward, dragging the rebar. The travel motor 5316 is then activated, driving the gear 5317 to rotate on the rack 5311, thereby moving the transport mechanism 53. Once in position, the piston rod of the electric cylinder 5322 retracts, driving the rebar downward, completing the transport operation.

[0079] In a further embodiment, a photoelectric sensor is provided on the receiving member 5423 for detecting whether material enters.

[0080] The conveying mechanisms 53 are provided with three at intervals in the front and rear; by setting up three conveying mechanisms 53, continuous operation is realized. When the steel bars after fixed length are conveyed to the threading device 2, the conveying mechanism 53 on the front side is reset. During the threading process, the next steel bar continues to be loaded, and fixed-length cutting and residual material discharge are performed. When the threading of the steel bar in the threading device 2 is completed, the next steel bar is loaded synchronously, and the middle conveying mechanism 53 conveys the threaded steel bar to the grinding device 3, and the front conveying mechanism 53 conveys the next steel bar to the threading device 2. After the ground steel bar is unloaded through the rear conveying mechanism 53, the middle conveying mechanism 53 continues to convey the threaded steel bar to the grinding device 3, thereby realizing continuous operation and improving work efficiency.

[0081] All power components of this equipment are connected to the PLC control system and controlled by the PLC control system.

[0082] The method of use of the present invention is:

[0083] Take the example of a 12-meter steel bar processed into a 9-meter steel bar with threaded ends.

[0084] 12 meters of steel bars enter from the left side of the feeding device 1, and the right end thereof enters the residual plate 127 of the residual material turning mechanism 12. When the steel bars enter and the length of the steel bars from the sawing machine 112 to the right end reaches 3 meters, the sawing machine 112 starts to cut the right side of the steel bars, and the residual material remains in the residual material plate 127; then the turning cylinder 126 starts, driving the turning part 123 to rotate forward based on the hinge point of the residual material support 122, driving the residual material plate 127 to rotate forward, thereby discharging the residual steel bars remaining in the residual material plate 127, and completing the fixed length of the steel bars.

[0085] After the steel bar is fixed in length, it continues to be transported to the right and enters the active conveying plate 1331 of the left first conveying mechanism, and then moves to the right to enter between the active pressure wheel 1323 and the driven pressure wheel 1325, and then the piston rod of the tightening cylinder 1327 is extended, driving the movable plate 1324 to move forward, so that the driven pressure wheel 1325 moves forward and cooperates with the active pressure wheel 1323 to press the steel bar, and then the conveying motor 1322 is started, driving the active pressure wheel 1323 to rotate, so that the active pressure wheel 1323 and the driven pressure wheel 1325 drive the steel bar to continue to be transported to the right, so that the right side of the steel bar enters the right active conveying plate 1331, and as the first conveying mechanism on the left conveys the steel bar, the steel bar enters the first conveying mechanism on the right in turn, and finally the left side of the steel bar is located in the residual material plate 127, and the right side is located in the driven conveying plate 142 of the first driven conveying mechanism 14.

[0086] After the steel bar is loaded, the transport mechanism 53 at the front of the transport device 5 is started, the piston rod of the electric cylinder 5322 is extended, and the receiving part 5324 is driven to move upward, dragging the steel bar, and then the travel motor 5316 is started, driving the gear 5317 to rotate on the rack 5311, thereby moving the transport mechanism 53. After it is in place, the piston rod of the electric cylinder 5322 is retracted, driving the steel bar to descend to the second active transport mechanism 21 and the second driven transport mechanism 22 of the threading device 2. After the transport is completed, the transport mechanism 53 is reset; then the second active transport mechanism 2 The conveying assembly 132 of 1 compresses the rebar and first conveys the rebar to the left until the left end of the rebar contacts the positioning plate 2344 of the positioning assembly 234 in the left threading mechanism 23. Once in place, the fixing fixture 233 of the threading mechanism 23 clamps the rebar. At the same time, the piston rod of the positioning cylinder 2345 of the positioning assembly 234 contracts, driving the positioning plate 2344 to rotate upward based on the connection point with the rotating rod 2343, opening the positioning plate 2344, and the threading machine 232 moves toward the left end of the rebar, enclosing the rebar for threading, completing the threading of the left end of the rebar. After the left end of the rebar is threaded, the second active conveying mechanism 21 drives the rebar to move rightward and reset, while the left positioning assembly 234 and the threading machine 232 reset. Then, the second active conveying mechanism 21 moves the rebar to the right again, completing the threading of the right end of the rebar in the above manner. After the right end is threaded, the second active conveying mechanism 21 moves the rebar to the left and resets, completing the threading of the rebar.

[0087] After the steel bar is threaded, the middle conveying mechanism 53 conveys the steel bar to the third active conveying mechanism 31 and the third driven conveying mechanism 32 of the grinding device 3. After the conveying is completed, the middle conveying mechanism 53 is reset; the third active conveying mechanism 31 first conveys the steel bar to the left to the left grinder 33, and the grinder 33 grinds the left end of the steel bar; after the left end of the steel bar is ground, the third active conveying mechanism 31 first conveys the steel bar to the right and resets it, and then conveys the steel bar to the right to the right grinder 33 to grind the right end of the steel bar; after the right end of the steel bar is ground, the third active conveying mechanism 31 moves the steel bar to the left and resets it, and the steel bar grinding is completed.

[0088] After the steel bar grinding is completed, the conveying mechanism 53 on the rear side conveys the steel bar to the unloading rack 41 of the unloading device 4. After the lifting component 532 of the conveying mechanism 53 descends, the steel bar slides down along the unloading plate 411 of the unloading rack 41 and enters the storage area 421 of the storage rack 42 for storage, completing the processing of a single steel bar.

[0089] After the first steel bar is transported to the threading device 2, the second steel bar continues to be loaded, and fixed-length cutting and residual material discharge are carried out in the loading device 1. The first steel bar is threaded in the threading device 2. When the first steel bar is threaded, the second steel bar is synchronously cut to length and loaded into the first conveying mechanism and the first driven conveying mechanism 14. Then the front and middle conveying mechanisms 53 operate synchronously. The middle conveying mechanism 53 transports the first steel bar to the grinding device 3 for grinding, and the front conveying mechanism 53 transports the second steel bar to the threading device 2 for threading. Then the third steel bar continues to be loaded. When the first steel bar is ground, the second and third steel bars are synchronously threaded and loaded respectively. The rear conveying mechanism 53 transports the first steel bar to the unloading device 4, the middle conveying mechanism 53 transports the second steel bar to the grinding device 3, and the front conveying mechanism 53 transports the third steel bar to the threading device 2. Then the fourth steel bar continues to be loaded. In this way, continuous processing of multiple steel bars is achieved.

[0090] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
