What is Electrical Heating Upsetter Machine?

In electrical-upsetting a high electric current at low voltage is passed through a bar section which is limited by contact electrodes of different potential and heated due to high current density and ohmic resistance to be heating (W=I^2R). Axial force applied by a hydraulic piston simultaneously causes the gathering of volume which results in an increasing distance between the electrodes. At the same time the anvil electrode must retreat to allow the workpiece forming.

Electrical Heating Upsetter Machine Introduction

Upsetter is used by the resistance heating characteristic of round bar with hudraulic system, heating and upsetting the end or middle section of round bar. It's the necessary equipment for the workpiece processing and forming.

What industries can Electrical Heating Upsetter Machine be applied?

Auto Parts manufacturing industry, Ship Manufacturing Industry, Kitchen Appliances Processing Industry, Electricity Industry, Metal Fabrication Manufacturing Industry

When could you use Electrical Heating Upsetter Machine?

  • In order to save the material.
  • Heating and upsetting of finished-product before forming, and smoothly follow-up processing procedure.
  • Save power and consumption, the heating efficiency is better than high-frequency.
  • Parts of related life safety: auto transmisson shaft, cooking knife for food and beverage industry, special auto parts for various car type.

Features & advantages of Electrical Heating Upsetter Machine

  • Economic: the old manufacturer produced engine valves by steel bars, cut to the required sizes through by NC lathe, re-heatring and pressing. This traditional production way is not only spend much time and also waste material. Using Electrical Heating Upsetter Machine is simultaneous heating and upsetting in one machine, and it could save 50% material to prevent secondary machining and waste man-power.
  • No environmental pollution by radiant heat, smoke or other emissions; easy to operate, high working efficiency.
  • The heating procedure is from inside to outside to assure the material sturcture well mixed and deep the crystal in perfect condition.
  • The surface of forging parts are smooth & without bur. The constitute is average spread & with best tensile strength. No carbides on the surface of heating parts, which can improve the quality of products.
  • Accuracy controlling of upsetting speed & dimension, any length & diameter are availble to manufacture by demand.

How to operate the Electrical Heating Upsetter Machine?

Completed setting the data parameters→ workpiece puts into the mold → start → upper seat pushing to setting position, electrodes clamping mold, auxiliary mold starts and clamps the workpiece → bottom seat goes forward to press the workpiece → pre-heating discharge starting → upper seat goes backward, forging vlotage discharge → bottom seat goes forward to setting position and finish
