Abstract

The invention discloses a vacuum insulation induction heating furnace for forging. The vacuum insulation induction heating furnace for forging is characterized by comprising a heating part and a workpiece access part; the heating part includes an induction heating device and a vacuum pumping system; the induction heating device includes a bracket, a vacuum insulation cover, an induction oil and temperature measurers; the vacuum insulation cover is positioned at the upper end of the bracket; the lower end of the vacuum insulation cover is opened; an induction coil is positioned in the vacuum insulation cover; the temperature measurers are uniformly distributed on the vacuum insulation cover; the vacuum pumping system is communicated with the vacuum insulation cover; and the workpiece access part includes a lifting mechanism, an access driving mechanism and an operation car. The vacuum insulation induction heating furnace for forging adopts an induction heating mode to a workpiece under vacuum condition, is higher in heating speed, heat utilization rate and temperature uniformity, can save the resource, and facilitates to save the cost.

Description

technical field [0001] The invention relates to a heating device for forging, in particular to a vacuum heat preservation induction heating furnace for forging. Background technique [0002] Forging processing is a common processing method for metal materials. Through forging, defects such as as-cast looseness produced in the metal smelting process can be eliminated, the microstructure can be optimized, and a complete metal flow line can be obtained at the same time, so that the processed workpiece has a better quality. mechanical properties. At present, most of the heating methods in the metal forging process are direct flame heating or resistance heating. These two heating methods are carried out in the air, and the forging process in the air can easily lead to Oxidation occurs on the new surface, which will not only affect the performance of the metal, but also increase the workload of forging, resulting in waste of resources, especially for some precious metals, and was...
