Advantages of steel tube cold drawing machine compared to general mechanical pipe expanding machine
- Dec 11, 2018 -

Compared with ordinary mechanical pipe expanding machines, steel tube cold drawing machine equipment has many advantages in application. It belongs to the backward core device, and the drawn steel pipe has high concentricity. This is because the hydraulic transmission runs smoothly, and the structure ensures that the drawing force action line is completely consistent with the axis of the steel pipe, the axis of the inner and outer molds, and the axis of the core rod, thereby improving the accuracy of the product without causing radial runout, and its coaxiality. And straightness is high.


The overall structure of the steel tube cold drawing machine is simple in design and easy to manufacture, and its various components are simple sections and easy to process. In addition, the frame of the prestressed frame structure improves the strength, rigidity and bearing capacity of the drawing machine. The basic structure of the equipment is simple. Since the cylinder block, the mold base and the tailstock are integrally formed by the eight support pipes and the four tie rod assemblies, under the action load, the pulling force is closed in the entire frame, and the foundation is not subjected to pulling. Machine working load, only bear the weight of the equipment, thus saving a lot of equipment base costs.


In the process of operating the steel tube cold drawing machine, since the hydraulic system adopts the plug-in valve integrated block work, the stepless speed regulation is realized, that is, the drawing speed thereof can be smoothly adjusted in a wide range, and the operation is flexible and convenient.
