1. The occurrence of cold-drawn honing tube concave
The reasons for this situation may be:
When drawing thin-walled tubes, the diameter reduction is too large or the transition of the steel pipe hammer head is too rapid.
The tube material is too thin.
The honing equipment is too old.
2. Disadvantages of cold-drawn honing tube concave
With the transparency and openness of the market, users have higher and higher requirements for oil cylinders, so as oil cylinder manufacturers, users have higher and higher requirements for cold-drawn honing tubes.
The use of inferior cold-drawn honing tubes will have the following effects:
The service life of hydraulic cylinders is short;
The cylinder barrel is prone to oil leakage;
The clearance between the piston rod, guide sleeve and cylinder barrel is not easy to match;
Affects the accumulation of long-term partners;
3. Treatment and solution of cold-drawn honing tube concave
The manufacturer needs to reasonably allocate the diameter reduction;
Check the hammer head to confirm whether the hammer head is flat and wrinkle-free;
Check whether the length and width of the tube material grinding position are necessary;
It is also important to timely repair and update the product equipment.
