Z28-40 Hydraulic Thread Rolling Machine

Z28-40 Hydraulic Thread Rolling Machine

A hydraulic thread‑rolling machine is a versatile cold‑extrusion forming machine tool. Within its specified rolling pressure range, it can perform thread‑rolling operations—producing straight or helical threads—on cold workpieces. This advanced non‑cutting process effectively enhances both the internal and surface quality of the workpiece; the radial compressive stresses generated during machining significantly improve its fatigue strength and torsional resistance, making it an ideal, energy‑efficient, low‑consumption hydraulic thread‑rolling process. First, adjust the pitch and set the distances between the three axes so that the three thread‑rolling dies form an approximately equilateral triangle relative to the workpiece. Then, engage the hydraulic manual gear and adjust the cylinder nut to press against the stopper, ensuring that the thread‑rolling die on the moving guide rail makes contact with the workpiece just as it exits.

Z28-16 Three-Axis Thread Rolling Machine

Z28-16 Three-Axis Thread Rolling Machine

What are the advantages of a three‑axis thread‑rolling machine? 1. High precision and high efficiency. Modern three‑axis thread‑rolling machines are far more “specialized” in thread production, producing threads with perfectly consistent shapes. 2. A single three‑axis thread‑rolling machine can save a great deal of money; hiring workers is becoming increasingly difficult these days. Ultimately, it’s better to invest in an automated machine that lasts for many years, significantly reducing costs in this regard. 3. In recent years, environmental protection and hygiene have received considerable attention. While some machines may cause environmental pollution to varying degrees, three‑axis thread‑rolling machines are characterized by zero emissions and no open flames, allowing operations anytime, anywhere, shortening project timelines without delay. 4. Excellent quality and high stability. For a three‑axis thread‑rolling machine to deliver reliable, worry‑free performance, its stability is paramount.

SJ-36 Type Diameter Reducing Machine

SJ-36 Type Diameter Reducing Machine

The SJ-36 diameter‑reducing machine is a non‑cutting machining device that offers high production efficiency, a simple process, ease of operation, material savings, and stable quality. It employs hydraulic technology to cold‑press and form the portion of round steel requiring diameter reduction by feeding it into a dedicated die cavity. This process significantly increases the density of the compressed section, thereby enhancing the material’s tensile strength, while maintaining its ductility and impact toughness. As a result, the strength of the threaded portion and the shank are uniform, eliminating the drawbacks associated with reduced tensile strength and impact toughness caused by lathe‑turned surface removal.

SJ-46 Type Diameter Reducing Machine

SJ-46 Type Diameter Reducing Machine

The SJ-46 diameter‑reducing machine is a non‑cutting machining device that offers high production efficiency, a simple process, ease of operation, material savings, and stable quality. It employs hydraulic technology to cold‑shrink and form the portion of round steel requiring diameter reduction by feeding it into a dedicated die cavity. This process significantly increases the density of the reduced section, thereby enhancing the material’s tensile strength, while maintaining its ductility and impact toughness. As a result, the strength of the threaded portion and the shank are uniform, eliminating the drawbacks associated with reduced tensile strength and impact toughness caused by lathe‑turned surface removal.

SJ-60 Type Diameter Reducing Machine

SJ-60 Type Diameter Reducing Machine

A diameter‑reducing machine is a non‑cutting machining device that offers high production efficiency, simple processes, convenient operation, material savings, and stable quality. It employs hydraulic technology to feed round steel, threaded steel, and similar workpieces into specialized dies for cold extrusion. This process significantly increases the density of the steel in the extruded parts, thereby enhancing their tensile strength—without compromising ductility or impact toughness. As a result, the strength of the screw shank and the rod section becomes uniform, addressing the drawback of lathe‑turned peeling, which typically reduces both tensile strength and impact toughness. The diameter‑reducing machine is an ideal solution for manufacturing anchor bolts, foundation screws, and long‑rod screws used in mining applications. 1. The diameter‑reducing machine is equipped with a lifting pile, on which wire ropes of appropriate length and diameter can be suspended.
