The causes and solutions of cold drawing honing pipe concave folding phenomenon

First, cold drawing honing pipe concave folding disadvantages

With the transparency and openness of the market, the user's requirements for the cylinder are becoming higher and higher, so the requirements for the cold-drawn honing pipe as the user of the cylinder manufacturing are also becoming higher and higher.

The use of poor quality cold drawn honing pipes will have the following effects:

Short service life of hydraulic cylinder;

The cylinder is prone to oil leakage;

The clearance of piston rod, guide sleeve and cylinder is not easy to match;

Influence the accumulation of long-term partners.

Second, the reasons for this situation may be:

Due to the empty drawing thin-walled pipe, the diameter reduction is too large or the transition of the steel pipe hammer head is too urgent.

Raw material steel pipe situation is too thin.

The honing equipment is too old.

Third, cold drawing honing pipe concave folding phenomenon our specific treatment method:

It is necessary for the manufacturer to allocate the reducing amount reasonably;
