Outline of pipe nipple threading machine :
pipe nipple threading machine is a multi-function cold extrusion machine. pipe nipple threading machine in its rolling pressure range of cold, the workpiece for thread, ruled, twill and other treatment; straight, helical and oblique spline gear rolling; straightening, reducing diameter, rolling and various forming rolling. The machine has a safe and reliable electro-hydraulic execution and control system. Each work cycle can be selected in manual, semi-automatic and automatic ways.
Rolling wire cold rolling process is an advanced non-cutting processing, can effectively improve the internal and surface quality of the workpiece.
When processed, the radial compression stress generated, can significantly improve the fatigue strength of the workpiece and the reverse strength. It is an efficient, energy saving, low consumption of the ideal process.
Processing principle of pipe nipple threading machine :
The principle of involute spline of small modulus on cold rolling machine.
L, R is a pair of involute rolling wheels with the same parameters, respectively installed in the rolling machine on the two main shaft. And can be rotated in the same direction as the drive mechanism.
R wheel can be driven by the cylinder for radial feed movement,
The L wheel can be adjusted by the adjustment mechanism, coinciding with the indentation of the R wheel on the surface of the workpiece P.
The workpiece P is clamped with two center holes,
Adjust the fixture can move the workpiece axial, when the force can be around the fixture on the O point and the machine axis parallel to the axis of a swing angle.
To ensure that the workpiece in the cold rolling process is always maintained with the two rolling wheel in the free roll state, while easy to clamp the workpiece.
Rolling wheel structure size, shape and position tolerance and technical requirements with reference to the rolling wheel and cylindrical measuring gear development, rolling wheel of the length of the common line or across the distance between the gears in the gears to calculate the material, the required material can be used Cr12MoV (Hardness 59 ~ 62HRC).
The pipe nipple threading machine can equipped the auto feeding and loading machine. pls inquiry for details.
