Fixture selection skills for induction hardening machine tools

The early induction hardening machine tools often use metal cutting machine tools to transform, because the basic requirement of induction hardening machine tools is to be able to rotate and move the workpiece. In order to improve productivity, it has been proposed that the speed of the working stroke is variable, and the return stroke is required to be fast. With the advancement of machinery manufacturing technology, the particularity of induction hardening machine tools has also been more fully guaranteed. ,

The characteristics of induction hardening machine tools are as follows:

⑴The machine tool only bears electromagnetic induction and does not bear the cutting load. Therefore, it basically runs at no load. The main shaft drive requires low power, but the no-load stroke requires fast speed to reduce maneuvering time and improve productivity. ,

⑵The adjacent parts of the machine tool, inductors and busbar transformers are affected by high and medium frequency electromagnetic fields, so keep a certain distance, and should be made of non-metallic or non-magnetic materials. If the metal frame is close to the electromagnetic field, it should be made into an open circuit structure to prevent the generation of eddy currents and heat. ,

⑶ Anti-rust and splash-proof structure. All parts such as guide rails, guide pillars, brackets, and bed frames that can be splashed by quenching liquid should be rust-proof or splash-proof. . Therefore, the parts of hardening machine tools are made of stainless steel, aluminum alloy, bronze, and plastic materials. Protective covers, splash-proof glass doors, etc. are indispensable.
