CN104046756A - Inductor capable of realizing induction quenching of three shaft-type parts of different diameters - Google Patents

Abstract

The invention relates to an inductor capable of realizing induction quenching of three shaft-type parts of different diameters. The inductor is composed of a contact plate, a transition wire and an active wire, and is characterized in that the active wire is composed of three arcs of different diameters and is quincunx-shaped. The invention has advantages as follows: induction quenching can be carried out on three shaft-type parts of different diameters in one device; quality of parts is raised; processing efficiency is enhanced and investment cost is minimized; and market demand for the inductor is wide.

Description

One can realize the induction hardened inductor block of the different axial workpieces of three sections of diameters

Technical field

The present invention designs a kind of inductor block, and particularly relating to one can be to the induction hardened inductor block of the different axial workpieces of three sections of diameters.

Background technology

To producing, to have three sections of diameters to differ method that larger component heat-treat be to change three times inductor block when the induction quenching in thermal treatment factory, adjust three times processing parameter, very inconvenience, What is more, if wheel box two axles are parts of a spline type, material is that middle carbon alloy is firm, tempering as early as possible after quenching, otherwise there is the danger of crackle, so as will keep the safety in production, need there be three equipment respectively to three sections of axle journals induction quenching simultaneously, the timely tempering of guarantee, although such heat treating method also can meet the demands, but working (machining) efficiency is low and the cost of labor of processing and the input of equipment larger, so can realize the induction hardened inductor block of the different axial workpieces of three sections of diameters in the urgent need to one

Summary of the invention

The present invention be exactly in order to address the above problem, overcome in prior art and there is no a kind of inductor block that three sections of different axial workpieces of diameter are quenched, the invention provides a kind of can be to a kind of inductor block that three sections of different axial workpieces of diameter are quenched.

For achieving the above object, technical scheme of the present invention is: described inductor block is made up of contact plate, excessively wire and active wires, it is characterized in that, described active wires is by the circular arc of three sections of different diameters and be the setting of " quincunx " shape and form.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

Fig. 1 has shown respectively with Fig. 2 that the present invention is a kind of can realize three sections of induction hardened inductor blocks of the different axial workpieces of diameter and three sections of axial workpiece front views that diameter is different, inductor block is by contact plate (1), excessively wire (2) and active wires (3) formation, and active wires (3) is by the circular arc of active wires A section, active wires B section and three sections of different diameters of active wires C section and be the setting of " quincunx " shape and form.In the time that the axial workpiece A section (4A) in axial workpiece (4) is quenched, inductor block can move to the lower end of axial workpiece A section (4A), axial workpiece A section (4A) axis is overlapped with the geometric centre A1 of active wires A section (3A), subsequently axial workpiece A section (4A) is heated from the bottom up and sprayed water, quench and end when axial workpiece A section (4A), stop immediately heating and water spray, digital control system moves to inductor block the lower end of axial workpiece B section (4B), and axial workpiece B section (4B) axis is overlapped with the geometric centre B1 of active wires B section (3B), start induction heating from the bottom up, spray quenching subsequently, quench to end until axial workpiece B section (4B) and stop after heating and water spray, digital control system moves to inductor block again the lower end of axial workpiece C section (4C), and axial workpiece C section (4C) axis is overlapped with the geometric centre C1 of active wires C section (3C), start from the bottom up heating, spray quenching, end until quench.

Claims (1)

1. can realize the induction hardened inductor block of the different axial workpieces of three sections of diameters for one kind, described inductor block is made up of contact plate (1), excessively wire (2) and active wires (3), it is characterized in that, described active wires (3) is by the circular arc of three sections of different diameters and be the setting of " quincunx " shape and form.
