Five points to pay attention to when operating a cold heading machine
(1) The end of the cold heading machine steel bar should be ground flat to ensure the accurate shape of the cold heading anchor head;
(2) After the multi station cold heading machine and other steel bar upsetting machines, a tensile test must be conducted to verify whether the strength of the anchoring head is qualified.
(3) The diameter of steel bars or wires should meet the requirements of the cold heading machine, and steel bars (wires) that are too coarse or too fine cannot be cold headed;
(4) Within the allowable range of the cold heading diameter of the punching machine, the position of the fixture (screw in or screw out) can be adjusted according to the required anchor head size to obtain a suitable amount of steel bar (wire) extension allowance;
(5) In the 120-130mm area of the steel bar (wire) cold heading part of the multi station automatic cold heading machine, rust removal and straightening are required.
