Abstract
An annealing device for screw threads comprises a heater and an induction coil, wherein the induction coil is wound through a copper tube; a wire passes through the copper tube, and the copper tube is connected with the heater; the induction coil is provided with a handheld device. The annealing device for the screw threads is formed by winding through the copper tube, so that the structure is simple; the handheld device enables convenient use; the annealing device is particularly suitable for annealing treatment of a small screw.
Description
Technical field
The present invention relates to a kind of annealing device, particularly relate to a kind of annealing device of screw silk tooth.
Background technology
Screw is conventional fastening piece, because it has higher hardness, therefore often understands owing to colliding with sleave or agomphosis in use, causes normally using.Although also there is the device about screw thread annealing at present, its complex structure, uses inconvenience, and cost is high.
Summary of the invention
The object of the present invention is to provide a kind of structure simple screw silk tooth annealing device.
The object of the present invention is achieved like this, and a kind of screw silk tooth annealing device, comprise well heater and induction coil, induction coil is copper pipe coiling, wears electric wire and be connected with well heater in copper pipe, and induction coil is provided with hand-held device.Annealing device of the present invention is formed by copper pipe coiling, and structure is simple, and is provided with hand-held device, easy to use, is particularly suitable for the anneal of the less screw of build.
In order to the screw silk tooth of applicable different size, the internal diameter of above-mentioned induction coil is 15-20mm, and length is 100mm.
In order to ensure that structure is reliable, the diameter of copper pipe is 5mm.
In order to ensure annealing effect, the power of above-mentioned well heater is 30kw.
In order to easy to operate, the two ends of above-mentioned copper pipe close up, and above-mentioned hand-held device is the insulation handle being packaged in copper pipe 3 two ends.
The present invention has following beneficial effect:
1, annealing device of the present invention is formed by copper pipe coiling, and structure is simple, and is provided with hand-held device, easy to use, is particularly suitable for the anneal of the less screw of build.
2, adopt annealing device of the present invention to realize short annealing, and only reduce the hardness of silk tooth, other performances of workpiece are not affected.
3, through the screw of annealing device anneal of the present invention, hardness reduces, and toughness strengthens, and is not easy to cause sleave or agomphosis phenomenon because collide with.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1. well heater, 2. induction coil, 3. copper pipe, 4. hand-held device.
Embodiment
