What are the maintenance contents of the wire rolling machine?

Even when the wire rolling machine is not in use, maintenance should be carried out on the equipment to prevent malfunctions that may delay work. Equipment that has not been used for too long is likely to malfunction, so it is important to pay attention to maintenance when idle. Below, we will intro......

What are the precautions for using hydraulic thread rolling machines?

When using a hydraulic wire rolling machine, we need to pay attention to the following ten key points. 1. The cooling liquid must use water-soluble emulsified coolant, and the use of oily coolant is strictly prohibited, and ordinary lubricating oil cannot be used as a substitute...

As the part “rolls” through the dies, the pressure applied by the plates creates the thread without cutting or removing material. A cut thread (also called a machined thread) is made by machining away the material in order to create the thread form. Cut threads, as the name implies, are made by cutt......

For the same reason, rolled threads are often much smoother, and damage resistant during handling than cut threads. Thread rolling changes the mechanical properties of the material by work hardening it, resulting in increased wear and fatigue resistance, as well as enhanced shear, tensile, and yield......

Thread rolling is a metal forging process that forms screw threads by passing material under high pressure through a set of hardened dies. In the thread rolling machine, dies are skewed or pitched relative to one another, so their axes are not parallel.

The materials most commonly used to make thread-rolling dies are high-speed tool steels, high-chromium tool steel, medium-alloy cold-work steel. Which are mostly Ferrous but other ductile materials such as brass, aluminium are also used with compromise in quality of the thread.
