Abstract
The invention discloses a rotary furnace for the nitriding of a tiny workpiece, and relates to gas nitriding equipment for tiny workpieces. The rotary furnace consists of a furnace body and a furnace pipe and is characterized in that the furnace body is arranged on a bracket; the furnace pipe is arranged in the furnace body; and a gas inlet and a gas outlet of the gas furnace are formed outside the furnace body. The furnace pipe can rotate, and the rotation speed is adjustable. The furnace pipe can tilt forward and backward. The rotary furnace disclosed by the invention has the advantages of novel and simple structure, advanced technology, uniform nitriding, improvement in productivity and the like, and is an economical and practical novel rotary furnace for the nitriding of a tiny workpiece.
Description
Technical field
Minimum workpiece nitriding rotary type stove of the present invention relates to a kind of gas nitriding equipment of minimal type workpiece.
Background technology
Traditional gas nitriding is to carry out in pit furnace or multipurpose furnace.Can guarantee quality product and productivity for large and medium-sized part.But for subminiature, external diameter is in 10mm, and thickness just needs frock clamp to assist to finish nitriding at 2mm with interior workpiece, but such way is so that the consumption of technique anchor clamps is very big, and can not guarantee minimum workpiece nitrided case uniformity, cause productivity greatly to reduce.
For existing problem in the above-mentioned prior art, a kind of novel minimum workpiece nitriding rotary type stove of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the objective of the invention is a kind of novel minimum workpiece nitriding rotary type stove of research and design.Exist in the prior art in order to solve: 1, technique anchor clamps consumption is very big; 2, can not guarantee that minimum workpiece nitriding is even; 3, the problem such as productivity losing.
Technical solution of the present invention is achieved in that
Minimum workpiece nitriding rotary type stove of the present invention is comprised of body of heater and flue; It is characterized in that body of heater is loaded on the support, flue is housed in body of heater, the inlet mouth of flue and air outlet are in the outside of body of heater.
Flue of the present invention can rotate, and rotating speed is adjustable.
Flue of the present invention can tilt forward and back.
Use procedure of the present invention is as follows:
At first minimum workpiece is loaded in the flue, flue is heated, but temperature is heated to 520-580 when spending, to ventilating in the flue, the gas that passes into is other gases that ammonia maybe can produce nitrogen, and the flow of ventilation is that the waste gas that overflows the air outlet can be lighted and gets final product; When nitriding body of heater as requested rotating speed carry out spinning, and can tilt forward and back; The nitriding soaking time is 30 minutes to 3 hours.
Advantage of the present invention is apparent, is mainly manifested in:
The present invention does not only need frock clamp, and because the rotation of the flue of rotary kiln, so that the workpiece homogeneous heating of nitriding, and the infiltration layer uniformity, not only guarantee quality product, and greatly reduced into the product cost.
The present invention has novel structure, simple, the advantage such as technique is advanced, nitriding is even, boost productivity, and it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
Description of drawings
The present invention has 1 width of cloth accompanying drawing, wherein:
Accompanying drawing 1 structural representation of the present invention.
In the drawings: 1, air outlet 2, body of heater 3, flue 4, inlet mouth 5, support
Embodiment
Specific embodiments of the invention are comprised of body of heater 2 and flue 3 as shown in drawings; It is characterized in that body of heater 2 is loaded on the support 5, flue 3 is housed in body of heater 2, the inlet mouth 4 of flue 3 and air outlet 1 are in the outside of body of heater 2.
Flue 3 can rotate, and rotating speed is adjustable.
Flue 3 can tilt forward and back.
The above; it only is better embodiment of the present invention; but protection scope of the present invention is not limited to this; all are familiar with those skilled in the art in technical scope disclosed by the invention, are equal to replacement or change and all should be encompassed within protection scope of the present invention according to technical scheme of the present invention and design of the present invention thereof.
