Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically a production line for sawing, threading, milling, and bending steel bars. Background Technology

[0002] Rebar sawing is a processing method that uses equipment such as a saw to cut rebar to a specific length requirement. The purpose is to cut long rebar raw materials into lengths that meet the needs of architectural design or engineering construction. Rebar sawing, threading, milling, capping, and bending are carried out in three processes. Specifically, a CNC sawing and threading production line is used to cut the rebar, thread it, and grind off burrs. Then, the thread protection cap is installed manually, and the rebar is bent into shape using a bending machine.

[0003] When collecting finished products, multiple sets of collecting rods are needed to organize and limit the finished products. Especially when adjusting the spacing, if the collecting rods are simply connected by plugs or threads, after long-term use, the plug-in type will wear out and wobble, and the threaded type will also loosen to a certain extent, affecting the collecting effect.

[0036] Specifically, the working process or principle of this steel bar sawing, threading, milling, and cap bending production line is as follows: During use, the steel bar raw material is placed on the stepped feeding rack 3, the steel bar packaging straps are untied, processing data is edited on the operating table 2, and processing begins. The feeding stair 4 pushes the steel bars one by one into the feeding trough 6. When the number of processed bars reaches the set quantity, the feeding stair 4 stops feeding. At this time, the feeding trough 6 transports the steel bars to the sawing position, and the saw 8 cuts the steel bars. After cutting, the tailing rack 7 flips out the remaining tail material. The steel bars to be processed are then transported forward to a fixed position through the discharge rack 9. When threading is required, the cut rebar on the discharge rack 9 is flipped into the unloading and receiving bin 10. When threading is needed, the horizontal moving frame 11 moves the rebar to the position of the conveying trough 12. The horizontal moving frame 11 is equipped with a rebar flipping plate, which flips the rebar into the conveying trough 12. The conveying trough 12 has six slots: two threading slots, two milling slots, and two capping slots. The horizontal moving frame 11 conveys the rebar to the threading machine 13 for threading. After one end of the rebar is threaded, the horizontal moving frame 11 flips it into the threading slot to process the thread on the other end. After threading is completed, the horizontal moving frame 11 flips the rebar into the milling machine 14. The conveyor trough 12 is used for deburring, and then the milling machine 14 mills the burrs on the other end. After processing, the steel bar is turned into the conveyor trough 12 of the capping machine 15. The conveyor trough installs a protective cap on the end of the steel bar. After installation, the steel bar is turned into the capping groove to install a protective cap on the other end. After installation, the steel bar is turned into the bending feed trough 16. If bending is not required, the bending feed trough 16 will turn the steel bar into the threading receiving bin 17. When bending is required, the bending feed trough 16 will convey the capped steel bar to the bending storage trough 18. When the steel bar is conveyed to the set position, the three sets of robotic arms 2 of the bending loading gantry 20 are activated. 001 will clamp the steel bar and move it onto the bending head 21. The bending clamp 23 will clamp the steel bar, and the bending head 21 will bend the steel bar into shape. After bending, the two sets of robotic arms 2401 of the unloading gantry 24 will clamp the steel bar, move it, and put it into the finished product receiving bin 25. The final processing is completed. When adjusting the spacing of the receiving rods 2503 or simply installing and disassembling the receiving rods 2503, you only need to rotate the threaded frustum 3022 with a screwdriver to insert the top of the threaded frustum 3022 between the bottom of the pressing rod 3034, so that it presses the support ring 3011, and the installation is completed. The reverse is disassembly.
