Characteristics and principle of steel straight thread rolling machine
Provider： Source：Baoding Jindi Machinery Co., Ltd Time：2019-04-11
The straight steel thread rolling machine is now an indispensable and important equipment on the construction site, which allows the steel bars to be transferred out of the thread and then connected to the sleeve, so that the steel bars can be better combined. Today we will explain in detail the principles and features of the equipment.
Equipment principle,
The principle of hydraulic cold heading is applied to achieve the purpose of plastically deforming the ends of the steel bars, so that the diameter can be increased by 4 to 6 mm, and then the upper threads are processed. It is required that the actual cross-sectional area of the steel bar after machining the thread is larger than the original cross-sectional area, which greatly increases the tensile strength of the joint. This upset threaded joint is completely broken in the base metal by tensile test. It is suitable for high-demand engineering reinforced concrete upsetting machine with hydraulic technology, upsetting steel bar, for straight thread connection technology, using sleeve connection joint . The equipment is suitable for the upright straight threaded steel joint made of HRB335 (II grade steel) and HRB400 (III grade steel) hot rolled ribbed steel with diameter of 14~40mm.
Features,
Easy to operate, no professional technology is required, and you can operate it yourself in ten minutes of training.
High production efficiency, each can be up to 300-500 heads, processing length 65mm
Wide range of machinable steel bars, compounding various standard requirements for steel bars
The bottom diameter of the thread is not less than the diameter of the steel base material, and the tensile strength can be fully exerted.
Machine equipment failure rate is small, parts that are not easily damaged
