SK508-2000t Tubing&Casing Necking Machine

SK508-2000T  Tubing&casing necking machine
Since there are the ellipticity and wall thickness error for tubing and casing,pipe end thread with black skin may occur during thread machining. Using necking machine to form the pipe end can eliminate black skin at pipe end, and improve the quality. It's especially suitable for special buckle thread processing.

Appearance of the pipe end after necking process

 Main functions and characteristics:


1.This series of necking machine can obtain large necking force under medium or low pressure system.
2.good work mobility in each cricle, can complete each circle in 12s.
3.Automatically control necking size, just enter the required necking size, to ensure that the necking error is within the rang of ±0.2mm
4.The design structure is compact;Compared with similar equipment, necking force is doubled under the same system pressure;
5.Realize the automatic and manual optional method, to facilitate customers to operate according to their needs;
6.For slightly curved tubes, the equipment provides an automatic centering mechanism to ensure accurate access to die cavity.
7.Use two-level transfer in the feeding process,to ensure accurate positioning of the feeding.
8.In the whole necking process of retraction, the pipe body is not subject to mechanical stress.
