1. The Tube-end Upsetting Machine introduction

The principle of tube end thickening is to deform the heated pipe end by upsetting and extruding equipment, so as to achieve the purpose of pipe end thickening and improve the connection strength of steel pipe. Moreover, the plastic metal is in the state of three-dimensional compression in the process of deformation, which is conducive to the forging forming and to ensure that it is full of difficult forming edges and corners, and saves materials. Due to the stable performance and high connection reliability of upsetting and extruding steel pipe, it has been widely used in oil and gas industry.

The disadvantage is that the blanking accuracy is high. If the feeding is insufficient, the defects such as folding and insufficient filling are easy to occur. If the feeding is too much, it will form a high longitudinal flash between the punch and the female die, which is easy to lock the shaft core and form a huge drawing force, which is easy to tear and break the mandrel.

2. Tube-end Upsetting Machine servo energy saving retrofitting project

After the original hydraulic control system is reformed, because of its closed-loop control and high control accuracy, the disadvantages of traditional technology can be completely solved. At present, it has been successfully applied to production practice
