GS Control Software
The Siemens controller used is PLC type S7-200 series with MP277 8” touch screen.
Hydraulic upsetting rams are servo controlled via the S7.
The use of a unique hydraulic module allows the main force axis to be controlled in the same manner and thus making the finite control of all weld parameter achievable to incredibly high repeatable levels.
The use of this control technology gives advantages in the fine setting of parameters and limits with the added bonus that operator use is easy via special front end menus and password protection of the process
TYPICAL APPLICATIONS:
Engine Valves
Drill pipe
A high current is passed into one portion of the material to be upset. Electrical resistance causes the component to heat up. Once this portion of the material reaches plastic state, cold material is pushed into the hot area via hydraulic force.
During open electrical upsetting, the bar material is positioned between the upsetting cylinder and the anvil plate or die. Two-part clamping jaws close around the bar and electrical current flows between the clamping jaws and anvil plate, heating the exposed portion of the component. The hydraulic cylinder exerts a controlled force on the cold end of the bar producing a shaped head. The material is upset to the required shape via the application of heat, pressure, flow and linear travel. In open upsetting techniques the component is then passed to a form tool (press) in the red hot state to finish. Closed techniques produce a finished component direct from the upsetting machine.
The upsetting axis is usually vertical and the stroke is hydraulically powered. The machines incorporate many features that ensure optimum cycle time, excellent repeatability, quick set-up and reliable operation for all types and sizes of valves.
