Abstract

The invention discloses a spring wire electromagnetic heating and annealing device. The spring wire electromagnetic heating and annealing device comprises a hollow shell, an electromagnetic coil positioned inside the shell, and two lampblack filter draught fans fixed in the shell and located at the two ends of the electromagnetic coil; air inlets of the lampblack filter draught fans downwards facethe electromagnetic coil; and air outlets of the lampblack filter draught fans face an exhaust outlet. A heating area is arranged inside the electromagnetic coil, the shell is provided with the exhaust outlet and a main air inlet, the annealing device is not in the mode of heating air in a furnace chamber, a spring wire is put into the heating area of the shell, the spring wire is heated by itself through magnetic induction, the heating power can be adjusted in real time in the heating mode, and the advantages of rapid temperature rise, high heat response speed and low energy consumption areachieved. A heat dissipating system is arranged inside the device and discharges heat energy generated by copper consumption of the electromagnetic coil in time, heat energy and lampblack generated bythe spring wire are sucked in from the air inlet and discharged from the exhaust outlet in the shell, and accordingly the better cooling and lampblack removing effects are achieved.

Description

technical field

[0001] The invention relates to the technical field of industrial heat treatment, in particular to a spring wire electromagnetic heating annealing device. Background technique

[0002] Spring is one of the most common and most used basic parts in daily life and industrial production. Springs are used in everything from children's toys to automated production equipment. The production process of spring generally includes the following steps: winding forming-heat treatment-end surface treatment-strengthening treatment-heat treatment-surface treatment, wherein winding forming refers to the initial winding of steel wire into a helical spring wire, the periphery of the spring wire The cross-section of the profile is roughly W-shaped, and the heat treatment can be one or more of oil quenching, annealing and other treatment methods.

[0003] Annealing refers to slowly heating the metal to a certain temperature and keeping it for a sufficient time, and then cooling ...

Embodiment Construction

[0026] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0027] Such as figure 1 , figure 2 As shown, the present invention provides a spring wire electromagnetic heating and annealing device for heating and annealing the spring in the spring production process. The housing of the device is a six-sided hollow cuboid structure, and includes a bottom plate 11, a The opposite top board 12, the left side board 13, the right side board 14 and the two end boards 15 located at the two ends in the length direction. Two support plates 10 are fixed under the bottom plate 11, and the width of the support plates 10 is obviously larger than the width of the housing. The support plates 10 can assist the installation and positioning of the device, but the support plates 10 are not necessary components. The main air inlet 151 is provided on the end panel 15, and the spring wire is put into the device from the main ai...
