Several common nozzle treatment methods

1. Tip processing procedure: cold shrinkage technology can be used, capillary tube can be extruded multiple times, and finally sealed, but the tip will not be completely sealed; heat shrinkage technology can also be used, and high-frequency heating treatment with precision instruments After being beaten by the equipment, it is finally extruded into a pointed shape.

2. Reducing necking: The necking is divided into oblique and straight. It is a kind of processing that combines thin-walled stainless steel capillary material with liquid compression port machine, through rubber extrusion die or metal extrusion die, and narrows the nozzle. Process.

3. Expansion process: insert the expander into the tube, leave a proper device distance at the beginning, and then advance the expansion rod so that the expansion rod, the expansion beads, and the inner wall of the tube are close to each other, and then use a wrench or a tube expander to drive it. If the expanding rod rotates clockwise, the expanding beads will rotate in the opposite direction, rolling on the inner wall of the stainless steel capillary tube to force the tube wall to extend and the tube diameter to increase; or to put the tube into the flaring machine and the nozzle to align with the mold surface Carry out CNC flaring processing.

4. Slotting processing: The stainless steel pipe can be slotted by stamping, slotting machine or laser; the specific method mainly depends on the size of the slot.
