What is thread rolling cylindrical dies?2021-04-15T10:06:53+00:00

Overview

Thread Rolling Cylindrical Dies is also called Thread Rolling Dies, mainly used for external thread processing, specifications include Metric, UNC / UNF, NPT / NPTF, RC / RP, BSW, BSF, Whit.s., Whit., PT & PS, US Tube NPT & NPS, Trapezoidal threads (English and metric) and bicycle threads, etc. Its precision level is classified into levels 1, 2, and 3, It has 2- and 3-Die Systems, so cylindrical Die mechanism can be classified as “Two rollers Die” and ”Three rollers Die”, meaning two or three areas of insertion.

Cylindrical Dies are ideal for a wide range of precision threaded parts. They are made for through-feed rolling and In-feed rolling. The quality of Thread Rolling Dies is stable and directly affects the production speed, yield, and efficiency of threads, and has a significant impact on the overall performance of the product.

Thread rolling cylindrical dies use precautions

  • The accuracy of the screw rolling machine, the vibration is large, and the operation is not working properly.
  • Thread rolling dies is aligned, the axial displacement of the rolling parts is axially displaced, and the screw thread is subjected to two stress of shear and extrusion.
  • The size of the rolled threaded wire blank is uneven, the surface is not cleared, sand wheels, oxidized skin, and dirty products.
  • The hardness of the rolling parts is uneven (8.8 bolts should be at 27~30 HRC; 10.9 should be at 35~37 HRC), preventing the high hardness (50~55 HRC) of the high hardness (50~55 HRC) of the non-backfire (50~55HRC) is mixed due to the harmonizing parts of the high hardness (50~55 HRC) of the non-return fire. In the backfire, its hardness is similar to the hardness of the thread rolling dies, causing a strapping.
  • The lubricant did not add a lubricant when rolling, causing dry friction, so that the temperature of the tip temperature increased to more than the thread rolling dies tempering temperature, the excessive tempering of the screw thread was softened, screw thread stack.
  • Thread rolling cylindrical dies must be fully demagnetized before the factory, and there is no residency, otherwise, it will accelerate the abrasive oil due to the addition of the screw-absorbent fine iron.

How to choose the material of the thread rolling dies?

Thread rolling cylindrical dies is a mold that deforms the metal at normal temperature, and the accuracy requires high. When rolling the metal, the frictional force of a large periodic extrusion and circumferential direction is subjected to a large periodic extrusion, and the working conditions are harsh, and the damage form is: wear, break, and disintegration.

Therefore, the choice of thread rolling dies material is very important. At present, the main materials in the market have Cr12MoVo or CR12, and there are 9SiCr, CrWMn, with high temperatures, river, and high wear resistance, the latter is quenching. Less use. In order to improve steel tissue, improve its toughness, to further increase the wear-resistant thread rolling dies preferably the material is CD53, better than Cr12MoVo, good toughness.

How many kinds of thread manufacturing processes?2021-04-19T02:47:31+00:00

Thread products sampleThe thread processing method mainly has two major categories: cutting and rolling processing. Cutting generally refers to a method of processing a thread on a workpiece with a molded tool or abrasive. Rolling is to use a forming rolling mold (for example: Thread Rolling Dies) to generate plastic deformation to obtain a threaded process.

  • Thread Cutting
    Generally referring to a method for processing threads on a workpiece with a forming tool or abrasive, mainly turning, milling, tapping, sleeve, grinding, grinding and cyclone cutting. When turning, milling, and grinding threads, the workpiece rotates each turn, the drive train of the machine, the mill, mill or grinding wheel moves accurately and uniformly and uniformly and uniformly.When tapping or sleeve, the tool (tap or blade) is relatively rotationally movable with the workpiece, and guided the tool (or workpiece) as axial movement by the first threaded groove. Generally, more threaded cutting tools are taps.
  • Thread Rolling
    The workpiece is plastically deformable with a thread rolling dies to obtain a process for obtaining a thread. Threads are typically carried out on a thread rolling machine or a flat-die thread rolling machine or an automatic lathe that is attached automatically, suitable for large quantities of standard fasteners and other threaded coupling.The rolled threaded surface can improve strength and hardness due to cold work, high materials utilization, and productivity are multiplied by cutting, and is easy to achieve automation, and the rolling die is long time. However, the rolling thread requires the hardness of the workpiece material to exceed HRC30, and the blank material used to roll the workpiece of different materials is different. The need for blank size accuracy is high, and the accuracy and hardness of the thread rolling dies is also high. The rolling dies can be divided into Thread Rolling Dies ( Thread Rolling Cylindrical Dies ) and Thread Flat Dies and Thread Planetary Dies.
