Automatic hydraulic anchor bolt steel bar reducing diameter shrinking necking thread rolling machine

Automatic machine works necking necking machine is not cutting equipment, in order to avoid having the production efficiency, simple process, easy to operate, saving raw materials, the advantages of stable quality. It is the use of hydraulic technology round, steel, etc. to be fed into the reduced diameter portion of the grinding wheel via a dedicated shrink molding, compression pressure portion can greatly improve the density of steel, thereby increasing the compressive strength. And ductility, impact toughness diminished, so that the threaded portion and the rod portion consistent strength, peeling lathe solved by reduced pressure and anti-punch toughness drawbacks can expand the diameter of round, anchor bolts, screws double construction, High-speed bridge screws, production of mining anchor, anchor bolts, screws pole of the ideal equipment.
