The Main Points And Maintenance Of Cold Heading Machine

Cold heading machines mainly include screw cold heading machines and nut cold heading machines. Cold heading is mainly used to manufacture parts such as bolts, nuts, nails, rivets and steel balls. The forging material can be copper, aluminum, carbon steel, alloy steel, stainless steel and titanium alloy, etc. The material utilization rate can reach 80~90%. Cold heading is mostly carried out on a dedicated cold heading machine, which facilitates continuous, multi-station, and automated production.

Key points of using manual cold heading machine

1. The diameter of the steel bar or steel wire should meet the requirements of the cold heading machine, and the steel bar (wire) that is too thick or too thin should not be cold-headed;

2. Derusting and straightening must be carried out in the 120～130mm area of the cold heading part of the steel bar (wire);

3. Within the allowable range of the cold heading diameter of the punching machine, the position of the clamp can be adjusted (screw in or out) according to the required anchoring head size, so as to obtain a suitable amount of steel (wire) extension;

4. After the steel bar is upset, it must undergo a tensile test to check whether the strength of the anchoring head is qualified;　

5. The end of the steel bar should be ground flat to ensure the accurate shape of the cold heading anchor;

Operate the cold heading machine in a safe condition, operate the cold heading machine according to the correct operation method, do not overload the use, check regularly, find the root cause of the problem and solve it in time, do not wait until the machine is completely unusable before remembering to repair it , Usual maintenance and maintenance can also increase the service life of the product.
