Upset forging machine|Steel Bar Reinforced|cold forged

The upsetting and straight thread connection technology uses a special upsetting machine to rough up the thread section to be machined at the end of the reinforcement so that the diameter of the upsetting part is increased to be larger than the diameter of the parent material. Afterwards, the upsetting part of the special steel pipe threader is used for threading, and then the threaded parts of the two rebar head threading threads processed by the same specification sleeve are connected with a wrench to complete the so-called rebar connection. The upsetting and straight thread connection technology has the advantages of stable performance, quick and easy connection, high qualification rate, and can also completely solve the problem of non-rotatable connection of steel bars.
