Description

Technical Field

[0001] This utility model relates to the technical field of rebar threading machines, and in particular to a large-diameter rebar threading machine. Background Technology

[0002] In the field of building construction, steel bars are used in large quantities, and large-diameter steel bars are generally connected using straight threaded sleeves. This involves splicing longer steel bars with several shorter ones, where sleeves are fitted onto the ends of adjacent short steel bars for threaded connection. This achieves the bridging of round steel bars.

[0003] In the prior art, patent document CN221435213U discloses a rebar threading machine, including a table, a guide rail, a first support plate, and a second support plate. The guide rail is laid on the table. The first support plate and the second support plate are slidably mounted on the guide rail by sliders. The sliders of the first support plate and the second support plate are movably connected by a first connecting rod and a second connecting rod. A connector is connected to the connecting shaft of the first connecting rod and the second connecting rod. The connector is connected and fixed to the output end of a cylinder by a tension spring. A motor is provided on the first support plate. The output end of the motor is equipped with a threading head through a reducer. A slide is movably mounted on the second support plate.

[0004] During use, it was found that when installing and threading long steel bars, the steel bars would tilt during the fixing process, which would affect the subsequent threading process. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a large-diameter rebar threading machine.

[0006] This utility model discloses a large-diameter rebar threading machine, including a worktable and support legs. Multiple sets of support legs are provided at the bottom of the worktable. The machine also includes a clamping and fixing component, a threading component, and an auxiliary support component. The clamping and fixing component and the threading component are respectively provided at the top of the worktable, and the auxiliary support component is installed on the worktable. In use, when the rebar is long, it is placed behind the auxiliary support component and fixed by the clamping and fixing component. Then, the threading component is operated to thread one end of the rebar. With the cooperation of the auxiliary support component, the balance of the rebar clamping is ensured, improving processing efficiency.

[0007] Preferably, the clamping and fixing assembly includes upright plates, a guide rod, a bidirectional lead screw, a No. 1 motor, moving blocks, clamping plates, and guide rollers. Two sets of upright plates are installed at the top of the worktable. A guide rod is fixed between the two sets of upright plates, and a bidirectional lead screw is rotatably mounted between them. A No. 1 motor is installed on one set of guide rods, and the output end of the No. 1 motor is connected to one end of the bidirectional lead screw. Two sets of moving blocks are threadedly connected to the bidirectional lead screw and slidably connected to the guide rod. A clamping plate is installed at the inner end of each of the two sets of moving blocks. Guide rollers are rotatably mounted between the two sets of upright plates. The reinforcing bar is placed on the two sets of guide rollers, and its position is adjusted. The two sets of guide rollers rotate adaptively. After adjustment, the No. 1 motor is started, causing the bidirectional lead screw to rotate. The two sets of moving blocks drive the two sets of clamping plates to move closer together in a mirror image. The two sets of clamping plates clamp and fix the reinforcing bar on the two sets of guide rollers, improving stability.

[0008] Preferably, the threading assembly includes a servo electric cylinder, a slide rail, a slider, a movable base, a second motor, a reducer, and a threading head.

A second motor and a reducer are mounted at the top of the movable base. The output end of the second motor is connected to the input end of the reducer, and the threading head is located at the output end of the reducer. Starting the second motor causes the reducer to drive the threading head to rotate, and the servo electric cylinder extends, causing the movable base to move the threading head closer to one end of the rebar while the threading head performs threading on that end of the rebar.

[0009] Preferably, the auxiliary support assembly includes a support plate, bolts, and a bracket. A slot is provided on the side of the workbench, and the support plate is slidably disposed in the slot. A bolt is provided on the top of the workbench, and a bracket is installed on the top of the support plate away from the workbench. A guide wheel is rotatably disposed on the bracket.
