Description

Technical Field

[0001] The utility model relates to the technical field of threading machines, in particular to a threading machine with adjustable feeding speed. Background Art

[0002] With the continuous development and progress of society, there are more and more high-rise buildings with reinforced concrete frame shear wall structures. The traditional beam-column node steel bar anchorage steel bar consumption is large, the load increases, the beam-column steel bar end is not easy to operate during construction, the binding is difficult, the construction cost increases, and the construction period is extended. The steel bar anchor plate is easy to process and install, and can replace the traditional 90° standard bent steel bar anchorage length. Compared with traditional construction, it can save 40% of the anchor steel bar, thereby saving costs. Therefore, it is increasingly favored by the construction industry. In order to install the steel bar anchor plate, it is necessary to process the threaded head that matches the steel bar anchor plate at the end of the steel bar to achieve mechanical anchoring of the steel bar.

[0003] At present, a rebar threading machine is disclosed in the patent number "CN217193086U", which includes a machine base, a rebar clamp for clamping the rebar to be processed, a translation device and a threading device, wherein the rebar clamp is arranged at one end of the machine base; the translation device includes a U-shaped translation frame, two horizontal guide rods and a translation drive mechanism, wherein the horizontal guide rods are arranged between the end of the machine base away from the rebar clamp and the rebar clamp, and the entities on both sides of the U-shaped translation frame are respectively adapted to the two horizontal guide rods, and can be driven by the translation drive mechanism to reciprocate along the horizontal guide rods; the U-shaped bend of the U-shaped translation frame faces the rebar clamp, and the threading device is arranged in the U-shaped bend of the U-shaped translation frame. By setting a U-shaped translation frame with a U-shaped bend facing the rebar clamp, and making the entities on both sides of the U-shaped translation frame respectively adapted to the horizontal guide rods and reciprocatingly movable, the threading device has good movement stability when processing the rebar thread head, and the processed thread head has high consistency, which can effectively improve the qualified rate of the rebar thread head;

[0004] However, the two existing construction steel bars are butt-jointed through threaded pipes, but in actual applications, there are threaded pipes of different lengths. In order to better butt-join the two construction steel bars, it is necessary to turn a thread head of suitable length on the construction steel bar. If the turning is too short, it will easily break, and if the turning is too long, the time consumed will also increase appropriately. In long-term processing operations, the work efficiency is reduced to a certain extent. Utility Model Content
