Information

It is known that many pipe fittings and fasteners have threads, but few people know the machining method of threads.This is certainly not of interest to people outside the industry, but it is helpful to know a little about threading methods and precautions.

For example, the pipe hoop is generally cold machined so that the thread blank within a certain diameter can be formed by the screw plate pressure.The plastic streamline of the thread part can be obtained without being cut, the strength is increased, the precision is high, and the quality is uniform, so it is widely used.In order to produce the thread diameter of the final product, the thread diameter of the blank is required to be different, because it is limited by factors such as the thread precision, whether the material is plated or not.Rolling thread is a process in which a thread is formed by plastic deformation.It is to use a rolling die with the same pitch and shape of the thread as the processed thread, while squeezing the cylindrical screw blank, while turning the screw blank,* will eventually transfer the tooth shape of the rolling die to the screw blank, so as to form the thread.

According to the method of processing the thread, the steel pipe external thread machining machine can be divided into: thread cutting machine.Such as thread lathe, milling machine, thread grinding machine, tapping machine, set of silk machine, etc., including thread lathe, milling machine and grinding machine with thread processing tool or grinding wheel processing various precision thread, thread cutting tool and measuring tool, workpiece and tapping machine with a specially designed respectively and a set of silk machine hand tap and plate processing production in a large number of nut and screw, etc.;

2. Thread rolling machine.Plastic deformation of the workpiece by forming the rolling die to obtain threads, such as wire rolling machine, wire rolling machine, etc., high productivity, suitable for large and large production of standard fasteners and other thread joints of the external thread.
