Forming Process of Hydraulic Thread for Thread Rolling Machine
Rolling is a process method in which the billets of certain metal materials are rolled by rolling tools with a certain cross-section, resulting in rational deformation in the production area
Rolling is a process method in which the billets of certain metal materials are rolled by rolling tools with a certain cross-section, resulting in rational deformation in the production area, thereby forming the corresponding cross-section of the workpiece.
From this, it can be seen that hydraulic screw thread is a kind of chip free threading method. The essence of a thread rolling machine is to use the plasticity of certain materials in the cold state to thread, causing the blank to undergo plastic deformation and create corresponding threads under the pressure of the rolling limit tool.
The process of rolling threads in a cold state has been in progress since 1831, when a thread control machine was first used to twist the drill bolts used to fasten railway sleepers. However, it was not widely used for rolling precision threads until 1940. This is mainly due to the fact that in the late 19th and early 20th centuries, the blank material was not suitable for rolling. With the further improvement of the mechanical properties of blank materials, as well as the successful development of precision hydraulic tools and higher technological performance thread rolling machines, the rolling processing technology of thread rolling machines has gained greater popularity, and can be used in carbon sodium "Alloy steel (including stainless steel, tool steel, bronze, brass, aluminum, stainless steel, drill, nickel, powder metallurgy, and plastic) is used for rolling processing various types of threads (including precision threads) on various blank materials, such as taps, engine anchor bolts, power drill bolts, spindle and screw threads, and threads on hollow thin-walled parts.".
In the process of hydraulic threading, the processed thread is the result of redistribution of the blank metal extruded from the working thread of the rolling tool.
