Description

Technical Field

[0001] The invention belongs to the field of steel bar processing equipment, in particular to a dual-motor threading and flat head integrated machine. Background Art

[0002] The all-in-one threading and flattening machine is a key piece of equipment that integrates rebar stripping, threading, and flattening, significantly improving rebar end processing efficiency. Existing dual-motor models utilize one motor to drive the stripping and threading components, while the other drives the flattening cutter head, enabling integrated multi-process operation.

[0003] However, the transmission systems of existing threading and flat head integrated machines mostly use cycloid transmission reducers or F-series hard-toothed wheel transmission reducers. When this type of reducer is used in conjunction with the through-going transmission guide rod, not only is the transmission efficiency limited, but the overall size of the equipment is also easily larger due to structural redundancy, and the vibration is obvious during high-speed operation, affecting the coaxiality and surface accuracy of steel bar processing; the cooling system design has limitations, and most of the time only the rib stripping area and flat head area are cooled, while the thread rolling processing area is often in a non-targeted cooling state. During the thread rolling process, the tool is in close contact with the steel bar and the friction is intense. Continuous high temperature can easily cause rapid wear of the thread rolling wheel, which not only shortens the tool life, but also causes a decrease in thread profile accuracy due to overheating, increasing the rework rate. Summary of the Invention
