1. Equipment application

This equipment is mainly used to make straight pipe to cone pipe by medium frequency induction heating.

2. Specifications

2.1Main technical parameters

The processing procedure is as follows: Adjust each part (heating temperature, oil cylinder propulsion speed) to the appropriate data, a key activation. Each part start work, medium frequency power supply start, then heat the core rod to 800 ℃ begin to insulation. Steel pipe roller and feeding auxiliary oil cylinder will push and fix the steel pipe to process in processing position. The sensors and core rod move to the steel pipe by oil cylinder. Auxiliary oil cylinder and core rod will down after fixing the steel pipe, from the pipe expanding start to finish.

The feeding Carmen automatically move and fix steel pipe large elbow, the sensors and mandrel go back to proper distance, the feeding Carmen leave the steel pipe automatically the core rod and sensors return back to the origin place. The supporting roller rise and push the finished steel pipe, the finished steel pipe run automatically into finished products area. The pipe expanding work is finished.

2.2 Accessories

Medium frequency power supply, automatic load system, unload machine, automatic positioning system, push system, sensors, hydraulic system, automatic control system and so on.

2.3 Pipe expanding machine has two control modes for choose, PLC automatic control, save manpower; Semi-automatic buttons way, touch screen display real time monitoring the whole.

2.4 Up-down material system and pushing feeding machine adopt PLC control, without manual intervention, it can coordinate automatically to produce with the pushing system at the same time. The equipment has high degree automation, only one people can operate the system. And the equipment has continuous working ability, low failure rate.

2.5 Human-computer interaction part (such as: control handle, button, load indicator devices), meet ergonomic rule, and it is easy to identify and operate in emergency situation. All outer parts are marked nameplate logo, easy to identify and operate in emergency situation.
