By the way that screw thread will be processed on the guide post of existing positioning core axle in present embodiment, then added by one group of 2 internal diameter of casing
Positioning core axle 1 is threaded together with one group of casing 2 with identical threaded interior hole, realizes that pipe end is automatic by the screw thread that work matches
The effect of positioning is welded, and when pipe end automatic welding needs the product using various calibers, does not need replacement specification and caliber
Identical positioning core axle only chooses the casing of the outer diameter to match in one group of casing 2 with identical threaded interior hole with caliber i.e.
The purpose to match with different size caliber product can be achieved.
In present embodiment, replacing has one group of casing, the 2 outer diameter mode of identical threaded interior hole can be by directly replacing not
Casing 2 with outer diameter same inner diameter realizes there is the side of one group of casing 2 of identical threaded interior hole in present embodiment using replacement
Formula replaces replacement positioning core axle, and because positioning core axle material is chromium-zirconium-copper, the cost is relatively high, and the process-cycle is long, in actual production
Wasting manpower and material resources, and one group of 2 material of casing with identical threaded interior hole is all chromium-zirconium-copper, but compared to replacement locating core
There is one group of casing 2 of identical threaded interior hole more to save material and reusable for axis, production and replacement.
