Electric steel bar heading machine, professional steel bar cold heading machine, automatic heading machine
A pplication:
The upsetting straight thread connection technology uses the special upsetting pre-end of the bar to be processed to upset the threaded section so that the diameter of the rough upsetting part is larger than the diameter of the base material. Then the upsetting part is threaded with a special sleeve threading machine, and then the two steel-head threaded parts are connected with the same size socket wrench to complete the so-called steel butt joint. Upsetting straight thread connection technology has the characteristics of stable performance, quick connection and labor saving, and high inspection qualification rate. At the same time, the problem that the steel connection cannot be rotated is completely solved.
In principle:
Use the principle of cold heading to plastically deform the steel
end, increase the diameter by 4-6mm, and then process the thread.
The actual cross-sectional area after threading is larger than the
cross-sectional area of the original steel bar, which greatly
improves the tensile strength of the joint. Through the tensile
test, this thickened threaded joint completely breaks in the base
material and is used in demanding engineering
Advantage:
Rebar upsetting refers to the use of the principle of cold heading
to plastically deform the ends of the rebar, then increase the
diameter of the rebar by 4-6mm, and then process the rebar threads.
The actual cross-sectional area of the rebar node after processing
is greater than the cross-sectional area of the original rebar
node. The tensile strength of the joint is greatly improved. The
tensile test showed that the upset threaded joints all broke in the
base material. The hydraulic system of the double-cylinder
upsetting machine adopts ultra-high pressure, low flow and low
energy consumption. High precision, good performance, high quality,
simple and convenient operation are its main advantages. In
addition, workers can be employed after the shortest vocational
training.
