Preparations before stamping of stainless steel elliptical head

Test for several minutes before stamping, confirm that the equipment is in good condition for stamping.

Correct selection of die according to process regulations, avoid misuse, measure blank thickness, check whether the specifications of the die are appropriate (to prevent the lower die from cracking), and then use it after qualified inspection by inspectors.

After the upper and lower die of the ellipsoidal head is installed on the hydraulic press, check the position of the upper and lower die. The clearance between upper and lower dies should be even, and fasteners such as bolts and nuts should be tightened to ensure safety.

Lubricant should be applied on the die before stamping. Lubricants are made up of 40% graphite powder and 60% oil, or graphite powder and water.

When it is found that the working face of blank holder is brushed before or during stamping, it should be polished smoothly in time.

The clearance between blank and blank holder should be as small as possible to ensure no bulging.

When pressing flat head (tube sheet), after the upper die passes through the lower die ring, it can continue to the working platform of the press to ensure that the head plane is leveled once.

After demoulding, the head and tube sheet are not allowed to contact with the upper die again or press twice to prevent oversize size.
