Abstract

The invention discloses a long and thin-walled tube induction hardening deformation control device. A water inlet hole is arranged in a pressing rod, the side wall of the pressing rod is provided with a cooling liquid inlet, the lower end of the pressing rod is provided with an upper pressing head, a water outlet hole is arranged in the upper pressing head, the water outlet hole is corresponding to the water inlet hole, a device base corresponding to the upper pressing head is provided with a lower pressing head, the device base is provided with an induction electrode, the induction electrode is connected to an induction coil, the induction coil is connected to a cooling liquid pipe and a water outlet groove is arranged around the lower pressing head. The long and thin-walled tube induction hardening deformation control device has a simple structure, is affordable, can be operated by simple processes, has good universality, and can realize long and thin-walled tube induction hardening only by outside spraying and inside sprinkling so that the surface satisfies quenching requirements and the core is not heated and does produce integral deformation.

Description

Technical field [0001] The invention relates to the technical field of induction hardening, in particular to an induction hardening deformation control device for slender and thin-walled pipe fittings. Background technique [0002] Rocker shafts and other similar products deform seriously after quenching. In order to reduce the occurrence of waste, the control measures adopted are: increase the straightening process of the workpiece after quenching and increase the machining allowance of the grinding surface. This increases the surface margin of the workpiece, wastes materials, wastes processing man-hours, and is undesirable from the product technology. [0003] Application number: 200720103891.9 Application date: 2007-03-20 An anti-deformation composite automatic quenching device for thin-walled slender steel pipes related to the quenching treatment of oil casing in the field of petroleum machinery and anti-cooling deformation technology, including a feed roller table (1) , Feedi...
