Reinforced Steel Pipe Upsetting Hydraulic Press

Reinforced steel pipe upsetting hydraulic press

Upsetting and pressing straight thread connection technology is to use a special upsetting machine to upset the thread section to be processed at the end of the steel bar in advance to increase the diameter of the upsetting part to be larger than the diameter of the base material. Then use a matching special threading machine to thread the upsetting part, and then use the same specification sleeve to connect the threaded parts of the two steel bars with a wrench to complete the so-called butt joint of the steel bars. The strong straight thread connection technology such as upsetting has the advantages of stable performance, labor-saving and fast connection, and high inspection qualification rate. It can also completely solve the problem of non-rotatable connection of steel bars.

Working principle:

 Use the principle of cold heading to plastically deform the end of the steel bar, increase the diameter by 4~6mm, and then process the thread. The actual cross-sectional area after processing the thread is greater than the cross-sectional area of the original steel bar, which greatly improves the tensile strength of the joint. The threaded joints after upsetting are all broken from the base material after tensile test, which is suitable for projects with higher requirements.

use:

Rebar straight thread rolling machine. It is mainly used for rolling straight threaded thread ends of ribbed steel in construction engineering, and is a key equipment for realizing steel bar connection. It can process HRB335 and HRB400 ribbed steel bars with a diameter of 16-40mm.

Features:

The steel bar straight thread rolling machine can complete the processing process from rib stripping to thread rolling in one clamping. The processed thread has full profile, high dimensional accuracy and high mechanical strength.

Both positive and negative threads can be processed.

The machine is simple to operate, compact in structure, reliable in work, and has a unique automatic opening and closing mechanism.
